Complete specification:
The following specification particularly describes the invention and the manner in which it is to be performed.
BACKGROUND
[0001] Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to being prior art by inclusion in this section.
FIELD OF THE INVENTION:
[0002] The subject matter in general relates to packaging closures. More particularly, but not exclusively, the subject matter relates to a tamper-evident closure system for containers.
DISCUSSION OF THE RELATED FIELD:
[0003] The safeguarding of packaged goods, especially those intended for direct consumption or use by consumers, such as foods, beverages, and medications, is of utmost importance. The inception of tamper-evident packaging represents a significant stride toward ensuring consumer safety and trust. Tamper-evident closures are designed to provide a visible indication if a product has been opened or altered after leaving the manufacturing facility, thereby alerting consumers to potential tampering or contamination.
[0004] Traditionally, a range of methods have been employed to ensure security of container closures. Yet, these approaches frequently fail to strike a perfect balance among ensuring security, maintaining ease of use, and optimizing manufacturing efficiency. For instance, adhesive labels used for the tamper-evidence purposes, that are already available in the market, can be easily mimicked or reapplied, making them unreliable indicators of tampering. Mechanical seals, on the other hand offer greater security, but can be challenging for consumers to open and might necessitate considerable alterations to conventional container designs, leading to escalated production costs. Additionally, the subtlety of tamper indication in many existing closures can lead to oversight by consumers, undermining the effectiveness of the tamper-evident feature and potentially endangering consumer safety.
[0005] A significant drawback of the existing tamper-evident closures is the reliance on the manufacturing and subsequent assembly of multiple components to create a tamper-evident closure. This process is not only time-consuming but also adds to the complexity and cost of production. The need for assembling these components post-manufacture represents a bottleneck in the production process, delaying time-to-market and inflating overheads.
[0006] In view of the foregoing, there is need for an improved tamper-evident closure that address the shortcoming of the existing closures, while maintaining the product’s integrity.
SUMMARY
[0007] In one aspect of the embodiment, a tamper-evident closure is disclosed. The tamper-evident closure is configured to be operably received by a bottle neck, to offer tamper evidence and facilitate controlled dispensing. The tamper-evident closure defines a first longitudinal axis. The tamper-evident closure comprises of a first member, a second member and a third member, wherein the first member, the second member and the third member are disposed along the first longitudinal axis. The second member is disposed between the first member and the third member. At least a portion of the first member is provided with internal threads for operably engaging the first member with the bottle neck and disengaging the first member from the bottle neck, wherein at least a portion of the bottle neck is provided with external threads 216. At least a portion between the second member and the first member is provided with first perforations, and at least a portion between the second member and the third member is provided with second perforations. At least a portion of the second member is connected to at least a portion of the first member towards the first perforations, and at least a portion of the second member is connected to at least a portion of the third member towards the second perforations.
[0008] The second member is provided with a plurality of first protruding members, wherein the plurality of first protruding members are disposed along an inner circumference of the second member, and the third member is provided with a plurality of second protruding members, wherein the plurality of second protruding members are disposed along an inner circumference of the third member.

The sealing member 140 may gradually taper away from the first longitudinal axis 108 of the tamper-evident closure 100. The taper enables better sealing of bottle opening, when the first member 102 is engaged onto the bottle neck 200.
[0021] In an embodiment, at least a portion of the first member 102 may be provided with internal threads 110 for operably engaging the first member 102 with the bottle neck 200 and disengaging the first member 102 from the bottle neck 200.
[0022] In an embodiment, at least a portion between the second member 104 and the first member 102 may be provided with a plurality of first perforations 112, and at least a portion between the second member 104 and the third member 106 may be provided with second perforations 114.
[0023] In an embodiment, the first perforations 112 and the second perforations 114 may be provided along the first longitudinal axis 108 in different horizontal planes.
[0024] In an embodiment, the first perforations 112 comprises of a first set of slots 128 and a first set of bridges 130, similarly the second perforations 114 comprises of a second set of slots 132 and a second set of bridges 134. The slots 128 and bridges 130 of the first set of slots and bridges may be, but not limited to, provided at equal intervals, similarly, the slots 132 and bridges 134 of the second set of slots and bridges may be, but not limited to, provided at equal intervals.
[0025] In an embodiment, length of each slot 128 of the first set of slots may be smaller than the length of each slot 132 of the second set of slots.
[0026] In an alternate embodiment, length of each slot 132 of the second set of slots may be smaller than the length of each slot 128 of the first set of slots.
[0027] In an embodiment, width of each bridge 130 of the first set of bridges may be smaller than the width of each bridge 134 of the second set of bridges.
[0028] In an alternate embodiment, width of each bridge 134 of the second set of bridges may be smaller than the width of each bridge 130 of the first set of bridges.
[0029] In an alternate embodiment, length of each slot of the first set of slots and width of each bridge of the first set of bridges may be equal to the length of each slot of the second set of slots and width of each bridge of the second set of bridges, respectively.
[0030] In an embodiment, one or more bridges 130 among the first set of bridges may be provided at an offset from one or more bridges 134 among the second set of bridges along the first longitudinal axis 108. This structural configuration enables easy detachment of the second member 104 from the tamper-evident closure 100 as the force applied to detach the second member 104 may be applied to break a single bridge 130, 134 among the bridges of the first set of bridges and the second set of bridges, at a given instance.
[0031] In an embodiment, at least a portion of the second member 104 may be connected to at least a portion of the first member 102 towards the first perforations 112, and similarly, at least a portion of the second member 104 may be connected to at least a portion of the third member 106 towards the second perforations 114.
[0032] In an embodiment, the second member 104 may be provided with an extending member 136, wherein the extending member 136 may extend from at least one end of the second member 104. The extending member 136 may be configured to enable detachment of the second member 104 from the tamper-evident closure 100. The extending member 136 may act a pull-off tab, which enables detachment of the second member 104.
[0033] In an embodiment, the first member 102 and the third member 106 may be separated into two different members, when the second member 104 is completely detached from the tamper-evident closure 100.
[0034] In an embodiment, the second member 104 may be provided with a plurality of first protruding members 116, wherein the plurality of first protruding members 116 may be horizontally disposed along an inner circumference of the second member 104.
[0035] In an embodiment, the plurality of the first protruding members 116 may be disposed closer to the second perforations 114 as compared to the first perforations 112.
[0036] This arrangement of the first protruding members 116 towards the second perforations 114 offers a comparatively higher strength to the second perforations 114, when compared to the first perforations 112, which in turn enables easy detachment of the second member 104 along the first perforations 112.
[0037] In an embodiment, each of the plurality of first protruding members 116 comprises of at least a first surface 120 and a second surface 122. The first surface 120 may extend away from an inner surface of the second member 104 towards the first longitudinal axis 108. The second surface 122 may extend away from the inner surface of the second member 104 towards at least a portion of the extended first surface 120. At least the second surface 122 may be provided at a first angle, wherein the first angle may be defined with respect to the inner surface of the second member 104, in a manner that the second surface 122 may be inclined away from the inner surface of the second member 104 towards the first longitudinal axis 108.
[0038] In an embodiment, the first surface 120 may extend in, but not limited to, a horizontal plane, wherein the first surface 120 may be provided perpendicular to the first longitudinal axis 108.
[0039] In an alternate embodiment, the first surface 120 may also be provided at an angle.
[0040] In an embodiment, the third member 106 may be provided with a plurality of second protruding members 118, wherein the second protruding members 118 may be disposed along an inner circumference of the third member 106. The positioning of the plurality of second protruding members 118 on the inner circumference of the third member 106 may be based on the requirements.
[0041] In an embodiment, each of the plurality of second protruding members 118 comprises of at least a third surface 124 and a fourth surface 126. The third surface 124 may extend away from an inner surface of the third member 106 towards the first longitudinal axis 108. The fourth surface 126 may extend away from the inner surface of the third member 106 towards at least a portion of the extended third surface 124. At least the fourth surface 126 may be provided at a second angle, wherein the second angle may be defined with respect to the inner surface of the third member 106, in a manner that the fourth surface 126 may be inclined away from the inner surface of the third member 106 towards the first longitudinal axis 108.
[0042] In an embodiment, the third surface 124 may extend in, but not limited to, a horizontal plane, wherein the third surface 124 may be provided perpendicular to the first longitudinal axis 108.
[0043] In an alternate embodiment, the third surface 124 may also be provided at an angle.
[0044] In an embodiment, the plurality of first protruding members 116 and the plurality of second protruding members 118 may be disposed in different horizontal planes, wherein said horizontal planes may be disposed perpendicular to the first longitudinal axis 108. The plurality of first protruding members 116 and the plurality of second protruding members 118 may be configured to restrict movement of the tamper-evident closure 100 along the first longitudinal axis 108, when the tamper-evident closure 100 is engaged to the bottle neck 200.
[0045] In an embodiment, the first protruding members 116 and the second protruding members 118 may be provided in a manner that each of the first protruding member may be interstitially disposed between two adjacent second protruding members 118, wherein the first protruding members 116 and the second protruding members 118 are disposed in different horizontal plane along the first longitudinal axis 108.
[0046] The strategic placement of the first protruding members 116 and the second protruding members 118 facilitates a simplified manufacturing process. This is particularly advantageous since tamper-evident closures 100 are predominantly produced through injection moulding, and the incorporation of the interstitial arrangement in the mould design not only streamlines manufacturability but also leads to reduced manufacturing and operational costs associated with the mould.
[0047] In an embodiment, at least a portion of the third member 106 may be provided with a chamfer 138, wherein the chamfer 138 may be disposed away from the second perforations 114 towards an opening of the tamper-evident closure 100. The chamfer 138 may be provided in a manner that it may extend away from the first longitudinal axis 108. The chamfer 138 may enable easy assembly of the tamper-evident closure 100 onto the bottle neck 200, when the tamper-evident closure 100 is initially pushed over the bottle neck 200 during assembly.
[0048] In an embodiment, direction of detachment of the second member 104 may be opposite to the direction of unscrewing of the first member 102 from the bottle neck 200. The direction of detachment of the second member 104 and the direction of unscrewing of the first member 102 from the bottle neck 200 may be along the first longitudinal axis 108. For example, if the second member 104 is configured to be detached from the tamper-evident closure 100 in a clockwise direction, then the direction of unscrewing of the first member 102 from the bottle neck 200 is in anti-clockwise direction, and vice-versa. As the directions are opposite to each other, the first member 102 tightens more securely around the bottle neck 200 rather than loosening or unscrewing from it, at the time of detachment of the second member 104 from the tamper-evident closure 100.
[0049] Furthermore, the first set of bridges 130 of the first perforations 112 may be configured to break when someone tries to tamper the tamper-evident closure 100.
[0050] In an embodiment, the first member 102 may be a cap, the second member 104 may be a tamper-evident band, and the third member 106 may be a sleeve.
[0051] In an embodiment, the tamper-evident closure 100 may be a unibody design.
[0052] In an embodiment, the tamper-evident closure 100 discussed in the foregoing may be configured to be engaged onto a bottle neck 200 with a specific structural configuration. Referring to FIGs. 2A-2B, structural configuration of the bottle neck 200 shall now be discussed in greater detail. Also, refer to FIG. 3 for the cross-sectional view of an assembly 300 of the tamper-evident closure 100 and the bottle neck 200.
[0053] In an embodiment, the bottle neck 200 may define a second longitudinal axis 206 along a height of the bottle neck 200, wherein the second longitudinal axis 206 may define a central axis of the bottle neck 200.
[0054] In an embodiment, the bottle neck 200 comprises of a first protruding ring 202 and a second protruding ring 204, wherein the first protruding ring 202 and the second protruding ring 204 may be spaced apart along the second longitudinal axis 206. The first protruding ring 202 and the second protruding ring 204 of the bottle neck 200 may be configured to interface with the plurality of first protruding members 116 and the plurality of second protruding members 118 respectively, when assembling the tamper-evident closure 100 onto the bottle neck 200.
[0055] In an embodiment, the first protruding ring 202 comprises of at least a fifth surface 208 and a sixth surface 210. The fifth surface 208 of the first protruding ring 202 may extend away from an outer surface of the bottle neck 200. The sixth surface 210 may extend away from the outer surface of the bottle neck 200 towards at least a portion of the extended fifth surface 208 in a manner that at least the fifth surface 208 may be provided at a third angle. The third angle may be defined in a manner that the fifth surface 208 may be inclined away from the outer surface of the bottle neck 200.
[0056] In an embodiment, the sixth surface 210 may extend in, but not limited to, a horizontal plane, wherein the sixth surface 210 may be provided perpendicular to the second longitudinal axis 206.
[0057] In an alternate embodiment, the sixth surface 210 may also be provided at an angle.
[0058] In an embodiment, the second protruding ring 204 comprises of at least a seventh surface 212 and an eighth surface 214. The seventh surface 212 of the second protruding ring 204 may extend away from the outer surface of the bottle neck 200. The eighth surface 214 may extend away from the outer surface of the bottle neck 200 towards at least a portion of the extended seventh surface 212 in a manner that at least the seventh surface 212 may be provided at a fourth angle. The fourth angle may be defined in a manner that the seventh surface 212 may be inclined away from the outer surface of the bottle neck 200.
[0059] In an embodiment, the eighth surface 214 may extend in, but not limited to, a horizontal plane, wherein the eighth surface 214 may be provided perpendicular to the second longitudinal axis 206.
[0060] In an alternate embodiment, the eighth surface 214 may also be provided at an angle.
[0061] In an embodiment, at least a portion of the bottle neck 200 may be provided with external threads 216, wherein at least the portion of the bottle neck 200 with the external threads 216 may be configured to operably receive at least the portion of the first member 102 with the internal threads 110, wherein the external threads 216 of the bottle neck 200 and the internal threads 110 of the first member 102 interface enable screwing and unscrewing of the first member 102 onto the bottle neck 200.
[0062] In an embodiment, upon assembly of the tamper-evident closure 100 onto the bottle neck 200, in a first state, the plurality of second protruding members 118 of the tamper-evident closure 100 may be configured to interface with the second protruding ring 204 of the bottle neck 200, while a first gap, along the first longitudinal axis 108, may be maintained between the plurality of the first protruding members 116 of the tamper-evident closure 100 and the first protruding ring 202 of the bottle neck 200. In the first state, the first surface 120 of each of the first protruding members 116 interface with the sixth surface 210 of the first protruding ring 202.
