FIELD OF THE INVENTION

The invention relates to the field of packaging surgical equipment.

The present invention relates more particularly to a packaging for suture.

STATE OF THE ART

Two-part suture packages are known from the state of the art, comprising a base and a cover. The base includes a receiving area for receiving a suture. The package further comprises means for locking the lid to the base to form a closed package.

Various means of locking the cover to the base have been proposed.

In a first type of suture packaging, the cover is glued to the base after a fusion process.

One disadvantage of such a bond is the use of chemicals and solvents which can migrate over the suture. Another drawback is that one or more sufficiently large flat areas are needed on the base for it to come into contact with the cover.

In a second type of suture package, the base has a peripheral wall, and a plurality of studs projecting from an inner surface of the peripheral wall toward the center of the base. The cover is made of a cardboard material, the outer periphery of which is substantially complementary to the inner surface of the peripheral wall. To close the package industrially, the lid is placed above the base, so that the edge of the lid is aligned with the inner surface of the peripheral wall. A tool provided with teeth presses the cover against the pins, so that the cover deforms slightly to pass the pins and get stuck under them. Thus, the cover is kept attached to the base at its outer edge,

However, the establishment of the cover of such a package is industrially difficult to implement; a large number of pins are in fact necessary for the cover to be securely attached to the base, which complicates the shape of the base and therefore its manufacture. In addition, the edge of the cover must be perfectly aligned with the peripheral wall of the base, otherwise the toothed tool presses too hard on the cardboard cover and leaves unsightly marks there, or presses too hard on the suture. itself at the risk of damaging it.

In a third type of suture package, a plurality of slits are formed in the base, and the cover includes a plurality of rectangular tabs. To attach the cover to the base, each rectangular tab is engaged in a corresponding slot.

However, the tabs are liable to slip out of the slots and thus lead to accidental separation of the cover and the packaging.

DETAILED DESCRIPTION OF THE INVENTION

Referring to Figure 1, a suture package comprises a base 1 forming a support for a suture.

The base 1 extends in a plane defined by two axes X1 and Y1.

Base 1 is racetrack-shaped in this plan.

The base 1 comprises an upper side 2, visible in FIG. 1, and a lower side 4 opposite the upper side 2.

The base 1 includes, on the upper side 2, a receiving area for receiving the suture.

The receiving area comprises a retaining channel 6 of the suture in a coiled position, and a parking area 8 of at least one end of the suture coiled in the channel, the parking area 8 being surrounded by the retaining channel 6.

The retaining channel 6 is defined by an outer peripheral wall 10 and at least one inner wall 1 1, the two walls 10, 1 1 projecting from the upper side 2. In other words, the retaining channel 6 is defined between the walls. 10, 1 1.

The peripheral wall 10 has an outer surface 12 forming a free outer edge of the base 1. This free edge 12 is graspable by an operator. The peripheral wall 10 also has an interior surface 14 opposite to the exterior surface 12. The interior surface 14 externally defines the retaining channel 6.

The inner wall 11 comprises a plurality of wall elements surrounded by the outer wall 12; in other words, the wall 11 is discontinuous. Alternatively, the wall 1 1 is continuous.

Retaining fingers 16 extend cantilevered from wall 11 to wall 12 in a plane parallel to the plane (X1, Y1). A day is left between a free end of each retainer finger 16 and the peripheral wall 10, so as to allow the insertion of a suture into the retainer channel through these holes. However, each finger 16 overhangs the retaining channel 6 so as to prevent an unexpected exit of a suture received in the retaining channel 6. A more detailed description of such fingers can be found in document WO2016066767.

The outer peripheral wall 10 has a height greater than the height of the inner wall 11.

The base 1 also has a through opening 18 between its two opposite sides, lower 4 and upper 2. This through opening 18 has a first part extending into the central parking area 8. The first part is extended by a second part which extends in the peripheral zone so as to locally interrupt the retaining channel 6. The second part of the through opening 18 further extends to the peripheral wall 10 so as to interrupt it locally. The through opening 18 thus forms an opening in the plane (X1, Y1) of the base 1, the opening being accessible from the free edge 12 of the base 1 formed by the peripheral wall 10.

The base 1 furthermore comprises a movable shutter 20 between an open position to reveal the through opening 18 between its two sides 2 and 4, and a closed position to partially block the through opening 18. The movable shutter 20 has a connection. 22 pivotally mounted to a portion of the base 1 integral with the peripheral wall 10, and a free edge 24 opposite the connection 22 and arranged to be aligned with the peripheral wall 12 when the movable shutter 20 is positioned in its closed position, as this can be seen in figure 1.

Being interrupted locally by the through opening 18, the retaining channel 6 has two orifices 26, 28 opening directly into this through opening (at the level of the second part of the through opening 18 interrupting the retaining channel 6). The two orifices 26, 28 are formed in two rectilinear sections 30, 32 aligned with the retaining channel 6.

The retaining channel 6 comprises the following successive sections: the rectilinear section 32 terminated by the orifice 28, a first curved section 34 rotating at 180 degrees, a rectilinear section 36 parallel to the section 22, then another curved section 38 rotating at 180 degrees, then finally the section 30 terminated by the orifice 26. The two curved sections 34 and 38 are for example symmetrical and located on either side of the parking zone 8. The curved sections 34 and 38 generally have a shape in C.

The two orifices 26 and 28, separated by the through opening 18, face each other and are aligned, so as to allow the suture to be wound in the retaining channel 6 in an ellipsoid path, devoid of abrupt deviations liable to locally wear the suture when it is unwinding and / or to cause resistance during its unwinding.

The base 1 further comprises a stiffening rib 40 projecting from the upper side 2 of the base 1.

The stiffening rib 40 extends between the through opening 18 and the retaining channel 6, at its curved section 34. Such a rib 40 makes it possible to increase the rigidity of the section 34 despite the presence of the through opening. 18, and also makes it possible to facilitate the filling of a mold used for the manufacture of the base 1, support 1.

The stiffening rib 40 comprises a curved wall 42 in the form of a C, which runs along the retaining channel 6 and more precisely the inner wall 11 of the latter.

The stiffening rib 40 further comprises a wall 44, a substantially rectilinear edge 46 of which extends inside the C formed by the curved wall 42 of the stiffening rib 40.

The base 1 further comprises a boss 48 projecting from the upper side 2 of the base 1, in the parking area 8.

The boss 48 has a top 50. The top 50 is substantially flat, rectangular in shape with rounded corners. The vertex extends in a plane parallel to the plane (X1, Y1).

The boss 50 further comprises a side wall 52 connecting the top to the base 1. The side wall 52 extends substantially perpendicular to the body of the base 1 in the parking zone 8, and relative to the top 50.

The boss 48 is hollow. It defines a cavity accessible from the lower side 4 of the base 1. The bottom of this cavity is formed by an internal surface 54 of the boss 48 (not visible in FIG. 1 but visible in FIG. 5). The boss 48 is a locally raised portion of the base 1 relative to the rest of the parking area 8, this raised portion being intended to serve as a support for a cover 62 of the packaging which will be described later. This locally raised portion also offers a gripping area for a

user. The user can in fact pinch this portion by means of a finger placed on the top 50 and another finger placed on the internal surface 54.

The base 1 further comprises a support 56 for one end of a suture. The support 56 is fixed to the upper side 2, in the parking zone 8. The support 56 is located between the boss 48 and the through opening 18. The support 56 is for example a foam in which a needle forming one end of the. a suture can be stitched and the needle can be easily pulled out. The support 56 is positioned in the parking zone 8 so that a needle inserted in this support 56 can partially overhang the through opening 18 (typically 1/3 of the needle). In this way, such a needle stuck in the support 56 can be grasped by means of an instrument introduced into the through opening 18 from the lower side 4,

Furthermore, the base 1 has a first slot 58 and a second slot 60. As will be seen below, these two slots 58, 60 have the function of locking the cover 62 of the packaging to the base 1.

By convention, the length of each slot 58, 60 is measured parallel to the Y1 axis, their width is measured parallel to the X1 axis, and their height is measured perpendicular to the plane (X1, Y1).

The two slits open into the upper side 2, that is to say the side of the base 1 on which the suture receiving zone is formed. They also open into the lower side 4 of the base 1.

More particularly, the two slots 58, 60 are formed in the parking zone 8 of the base 1, surrounded by the retaining channel 6.

The first slot 58 is formed in the side wall 52 of the boss 48. The first slot 58 is more precisely formed in a portion of the side wall of the boss 48 facing the through opening 18.

The first slot 58 is rectangular in shape. We denote by L1 its length. Its height is small compared to its length L1.

The second slot 60 forms part of the through opening 18.

The second slot 60 is delimited by the movable flap 20 and the stiffening rib

40. More specifically, the second slot 60 is formed between the substantially rectilinear edge 46 of the wall 44 of the stiffening rib 40, and an edge of the movable flap 20 substantially parallel to the edge 46.

Preferably, the wall 44 has a small rounded recess, so that the substantially rectilinear edge 46 has a curved central portion.

The first slot 58 is substantially rectangular in shape. It has a length L1 and a width of small dimension compared to its length L1.

The two slots 58, 60 are substantially parallel to the axis Y1.

The base 1, in one piece, is made by molding. The base 1 is for example made of plastic.

Referring to Figure 2, the packaging further comprises a cover 62.

The cover 62 is a sheet made of flexible material, typically of paper or cardboard, where appropriate plasticized. The sheet extends in a plane defined by two axes X2 and Y2.

The cover 62 is intended to at least partially cover the suture receiving area formed on the upper side 2 of the base 1.

The cover performs the following functions in particular:

• help protect a suture received in the reception area of ​​the base, and in particular,

· Bring moisture to a suture contained in the packaging, during a process of sterilization of this suture with ethylene oxide;

• in the case of absorbable sutures, ensure a low level of moisture in the absorbable suture contained in the package. In fact, the humidity will be fixed in priority on the cardboard of the cover rather than on the suture.

· Serve as an information medium.

The cover 62 has an upper side 64 and a lower side 66 opposite the upper side 64. The lower side 66 is intended to be pressed against the base 1, and the upper side 64 is intended to form an outer surface of the package formed. by assembling the base 1 and the cover 62. On the upper side 66 is typically written information relating to a suture intended to be received in the package.

The cover 62 has an outer peripheral edge 68 which is substantially complementary to the inner surface 14 of the outer peripheral wall 10 of the base 1. Thus, the cover 62 can be placed on the upper side 2 of the base 1 so as to be surrounded by the outer peripheral wall 10, without there being a gap between the outer peripheral edge 68 of the cover 62 and the peripheral wall 10 of the base 1. In such a position of the cover 66 relative to the base 1, called the closed position, the orientation of the cover 62 relative to the base 1 is such that the axis X2 is parallel to the axis X1, the axis Y2 is parallel to the Y1 axis, and the lower surface 66 of the cover 62 rests against the top 50 of the boss 48 and against the retaining fingers 16.

The cover 62 also has a through opening 70 having the same shape as the through opening 18 formed in the base 1.

The through opening 70 is arranged so as to be superimposed at least in part with the through opening 18 of the base 1, when the cover 62 is positioned on the base 1 in the closed position.

The cover 62 includes a first tab 72 as well as a second tab

74.

In what follows, the geometry, location and dimensions of the tabs 72, 74 are discussed. By convention, the length of part of one of the tabs is measured parallel to the Y2 axis and its width is measured parallel to the X2 axis.

The first tongue 72 is intended to be engaged across the first slot 58 of the base 1.

The first tab 72 is formed by simply cutting the sheet 62.

Referring to Figure 3, the first tab 72 has an L-shape.

The first tongue 72 comprises an intermediate portion 76 and a free end portion 78.

The intermediate portion 76 is intended to extend across the first slot 58. The intermediate portion 76 is connected to the rest of the sheet of the cover 62 by a straight fold line 80. The fold line 80 is parallel to the line. Y2 axis. The fold line 80 facilitates pivoting of the first tab 72.

Alternatively, the line 80 is not a fold line but simply a line of demarcation between the second tongue 74 and the rest of the cover 62, so as to allow the tongue to return naturally to a position substantially parallel to the rest of the cover. 62, and also make the tongue more robust.

The intermediate portion 76 is of length L3 less than or equal to the length L1 of the first slot 58.

The free end portion 78 extends the intermediate portion 76 opposite the fold line 80; an elbow 82 of the first tongue 72 is formed in the portion 78 (this elbow 82 can also be considered as a point of the L).

The free end portion 78 is of length L4 greater than the length L1 of the first slot 58. As will be seen below, this makes it possible to prevent the first tab 72 from coming out of the first slot 58, once the tongue 72 has been engaged in the slot 58 so that the free end portion 78 of the tongue 72 opens out of the slot 58 on the lower side 4 of the base 1, and this when the cover 62 is in the position of closing.

The free end portion 78 has a side edge 83 perpendicular to the fold line 80.

More precisely, the two intermediate portions 76 and 78 of the free end are separated by a line 77 parallel to the fold line 80. They are also delimited by lateral edges 760, 761 for the intermediate portion 76 and 780, 83 for the free end portion 78 which extend perpendicular to the fold line 80. The two side edges 760 and 780 are aligned.

On the other hand, the free end portion 78 being longer than the intermediate portion 76, considered parallel to the axis Y2, the edges 761 and 83, mutually parallel, are not aligned. The edge 83 of the free end 78 is located beyond the free edge 761 of the intermediate portion 76. The edges 761 and 83 are separated by the length of the elbow 82.

The free end portion 78 has a width 14 less than the length L1 of the first slot. This allows insertion of the free end portion 78 in the first slot, when the cover 62 is oriented at 90 degrees relative to the base 1 (that is to say when the axes X1 and X2 are perpendicular and when the axes Y1 and Y2 are also perpendicular, the two planes X1, Y1 and X2, Y2 remaining parallel to each other).

The two portions 76, 78 of the first tongue 72 are for example of rectangular shape.

Returning to FIG. 2, the second tab 74 is intended to be engaged in the second slot 60.

The second tongue 74 is of length L5 less than the length L2 of the second slot 60.

The second tongue 74 also has a curved free edge 86 that is convex, for example in the form of a portion of a circle.

The second tab 74 is formed in the sheet of the cover 62 after cutting a C-shaped hole 84 therein. The curved free edge 86 of the second tab 74 is part of the edge of this C-shaped hole.

Alternatively, the second tab is formed by a simple cutout of the cover, for example in the shape of a C, without forming an orifice 84.

The second tongue 74 is connected to the base by a second line extending parallel to the fold line 80. The second line is not, however, a fold line; it is simply a line of demarcation between the second tab 74 and the rest of the cover 62. It is nevertheless possible to provide that the second line is a second fold line parallel to the fold line 80.

The distance, measured parallel to the axis X2, between the two lines is substantially equal to the distance separating the complementary slots which receive the tongues 58, 60. Thus the tongues 72 and 74 extend on the outside of the slots after introduction. .

The two tongues 72, 74 extend in two opposite directions. In this way, while the cover 62 is in its closed position, an accidental exit of the second tab 74 from the second slot 60 by bending the cover is made less easy.

The two slots and the two complementary tongues are arranged in the vicinity of the longitudinal ends of the base and of the cover of elongated racetrack shape.

The packaging comprises means for locking the cover 62 at the base 1.

These locking means comprise the slots 58, 60 formed in the base 1 and the tongues 72, 74 formed in the cover 62. This locking function is more fully described below.

Locking method of the cover at the base

The cover 62 is locked to the base 1, so as to form a closed package for suturing, as follows.

A suture has previously been wound into the retaining channel 6. At least one end of the suture comprising a needle (for example two opposite ends of the same suture) escapes out of the retaining channel 6 through one of the holes 24 and 26. The needle of this suture is stuck in the support arranged in the parking zone 8.

The lower surface 66 of the cover sheet 62 is positioned against the upper side 2 of the base 1. The cover 62 oriented at 90 degrees relative to the cover 62 (that is to say when the axes X1 and X2 are perpendicular and when the axes Y1 and Y2 are also perpendicular). In this orientation, the lateral edge 83 of the free end portion 78 of the first tongue 72 is engaged in the first slot 58 of the base 1 by the upper side 2, by translation of the cover 62 relative to the base 1.

To enter the first slot 58, the first tab 72 is slightly inclined relative to the rest of the sheet forming the cover 62, by folding along the fold line 80, as can be seen in Figure 4. However, as the first slot 58 is formed in the side wall 52 of the boss 48, this engagement is effected without the first tongue 72 being strongly stressed in bending. The engagement of the first tongue 72 in the first slot 58 is thus facilitated.

The side edge 83 of the free end portion 78 of the first tongue 72 emerges from the slot 58 through the lower side of the base 1, and thus lies in the internal cavity defined by the boss 48, on the lower side 4 of the base 1. base 1, as shown in figure 5.

The cover 62 is then rotated around an axis perpendicular to the planes (X1, Y1) and (X2, Y2), over an angle of approximately 90 degrees, so that the cover 62 reaches the closed position described above. . During this rotation, the free end portion 78 of the first tab 72 is fully engaged in the first slot 58 of the base 1 by the upper side 2, then comes fully out of the slot 58 of the lower side 4 of the based. The elbow 82 formed in this free end portion is aligned with the internal surface of the side wall of the boss 48 in the vicinity of the first slot 58, thus forming a stop which prevents the first tab 72 from exiting the first slot. 58, as can be seen in figure 6.

Furthermore, during this rotation, the second tab 74 is brought closer to the second slot 60 until the curved edge of the second tab 74 comes into contact with the wall 46 of the rib defining an edge of the second slot 60. The second tab 74 is engaged in the second slot 60 by slightly bending the second tab 74 relative to the remainder of the cover sheet 62. The second tab 74 is engaged in the second slot 60 by slightly bending the second tab 74 by with respect to the remainder of the cover sheet 62. This flexing can be initiated either during rotation to the closed position or after the cover has reached the closed position.The fact that the second tongue 74 is of curved shape makes it possible to facilitate sliding of the second tongue 74 under the wall 44 defining the edge 46 of the second slot 60.

Figure 7 shows the second tab 74 engaged in the second slot 60 while the cover 62 is in the closed position, and Figure 8 is a more general view of the packaging while the cover 62 is in the closed position .

Once the second tab 74 has been engaged in the second slot 60, the cover is locked in rotation, which has the effect of locking the cover 62 more securely to the base 1.

In the closed position, the cover 62 covers at least part of the suture reception area, in order to protect the latter.

There is shown in Figure 9 a packaging for suture according to a second embodiment, in which most of the features of the first embodiment are found, in particular the first slot 58 and the first tab 72. This packaging however differs from the packaging according to the first embodiment shown in Figures 1 to 8 in that it comprises a second tab 75 formed in its cover, and a second slot 61 formed in its base, which are oriented differently from the tab 74 and the slot 60. In fact, the second tab 75 of the packaging according to the second

embodiment is oriented in the same direction as the first tab 72, and not in an opposite direction. Furthermore, the second slot 61 is arranged to allow a double insertion of the two tabs 72, 75 in the two slots 58, 61, as was already the case in the packaging according to the first embodiment. In other words, the packaging according to this second embodiment comprises two tongues 72, 75 extend so as to be able to be inserted respectively into the two slots 58, 61 formed in the base in the same direction. Such an arrangement of the tabs has the advantage of preventing even more effectively an accidental exit of the second tab 75 from the second slot 61, compared to the first embodiment. Indeed,

The invention is not limited to the embodiments shown in the figures. In particular, although an L-shape is particularly advantageous for the first tab because of its easy character to manufacture and to engage in the first slot 58, the first tab may have other shapes adapted to be blocked across the body. the first slot 58 following a rotation of the cover relative to the base.

Provision can be made for the first tab to be of a suitable shape so that its locking can be implemented after a rotation at an angle less than or greater than 90 degrees relative to the cover.
