DESC:FIELD
The present disclosure generally relates to fluid dispensing packaging.
DEFINITION
Fluid: The term ‘fluid’ hereinafter refers to fluids, liquids or slurries including semi-viscous material such as gels, soap slurries, creams and lotions.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Nowadays, to lower the hazardous effects of plastic, products are packed in packaging made of recyclable material which could be plant-based or starch-based materials, cardboards, virgin or recycled papers. However, hitherto it has not been possible to practically make dispensers out of these materials because such materials can easily be deformed, especially when forces are applied thereon. Further, packaging made of recyclable material does not allow storage of fluids for a very long period of time as the fluid seeps into the material.
There is therefore felt a need for a dispenser that can be industrially made with recyclable materials to alleviate the aforementioned drawbacks.
OBJECTS
Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:
It is an object of the present disclosure to ameliorate one or more problems of the prior art or to at least provide a useful alternative.
One object of the present disclosure is to provide a fluid dispenser.
Another object of the present disclosure is to provide a fluid dispenser that can be industrially manufactured.
Yet another object of the present disclosure is to provide a fluid dispenser that can be manufactured on automatic machines.
Still another object of the present disclosure is to provide a fluid dispenser that is manufactured from recyclable materials.
Another object of the present disclosure is to provide a process for making a fluid dispenser.
Another object of the present disclosure is to provide a process for making a fluid dispenser which allows manufacturing of the dispenser in a simplified manner in an automatic machine.
Other objects and advantages of the present disclosure will be more apparent from the following description when read in conjunction with the accompanying figures, which are not intended to limit the scope of the present disclosure.

A fluid dispenser (10), of the present disclosure, will now be described in detail with reference to Figure 1 through Figure 31.
Figure 1 illustrates the fluid dispenser (10) (hereinafter referred to as ‘the dispenser (10)’). Figure 2 illustrates an exploded view of the dispenser (10) of Figure 1.
The dispenser (10) comprises a carton (100) configured to store fluid therein. The carton (100) is formed from a laminated blank folded to form a set of sections which in their operative folded configuration are folded towards each other using a machine folding process to form base panels (137A, 137B), side panels (125A, 125B, 125C, 125D) and top panels (130A, 130B) of the carton, wherein the top panels (130A, 130B) form a multilayered resisting platform against deforming forces applied from top.
Figure 3 illustrates a blank (105) for the dispenser (10) of Figure 2.
In an embodiment, the blank is made from a packaging substrate is of a partially recyclable or completely recyclable material that is not only light in weight but also eco-friendly and is non-toxic.
In another embodiment, the packaging substrate comprises a plurality of layers including a layer of paper board and a composite layer. The substrate is laminated by at least one outermost polyethylene layer provided on both the inner surface and the outer surface of the substrate. The different layers of the substrate contribute to the above desired characteristics and further can be used to make the dispenser (10) last till at least four refills.
In an embodiment, rolls of a packaging substrate are passed through a cutting machine that cuts out blanks (105) of the desired shape from the substrate.
In an embodiment, the composite layer acts as an oxygen barrier to prevent reaction of outside air with the fluid stored in the dispenser (10). The polyethylene layer helps prevent seepage of the fluid from inside the carton (100). In an embodiment, the polyethylene layer provided on operative outer surface of the substrate helps in binding the side panels (125), and the bottom panels (137A, 137B) and top panels (130A, 130B) with each other, thus eliminating need for dependence on adhesives for binding. In another embodiment, the panels are heat sealed with each other, wherein the heat sealing is enabled by the polyethylene layer. The configuration of the blank (105) as mentioned above, helps in making the carton eco-friendly.
In one embodiment, the paper board has varying thicknesses varying between 0.35mm to 0.60mm depending on the cross section or size.
In one embodiment, the polyethylene layer can vary in thickness depending on the paperboard thickness. In yet another embodiment, the polyethylene layer provided on the outer surface can also vary in thickness depending on the paperboard thickness.
In an embodiment, the blank (105) has a set of first fold lines configured thereon to extend from an operative top edge of the blank (105) to an operative bottom edge of the blank (105), a set of second fold lines configured on an operative bottom portion of the blank (105), and a set of third fold lines configured on an operative top portion of the blank (105). The blank (105) is configured to be folded along the first fold lines to define side panels (125A, 125B, 125C, 125D) of the carton (100). Figure 4 illustrates the blank (105) of Figure 3 in a partially-folded configuration. Figure 5 illustrates the blank of Figure 4 in a folded configuration defining a sleeve. The side panels (125), after being folded, are attached to each other as shown in Figure 6 to form an open carton. The blank (105) further is configured to be folded along the second fold lines to define a first base panel (137A) and a second base panel (137B) of the carton (100), and along the third fold lines to define a first top panel (130A) and a second top panel (130B) of the carton (100). The first base panel (137A) is configured to be folded over the second base panel (137B) to form a flat base (135) of the carton (100), as shown in Figure 7 through Figure 12. The first top panel (130A) is configured to be folded over the second top panel (130B) to form a substantially rigid flat top (130) of the carton (100).
The dispenser (10) further comprises a depression (115) configured on the carton along a longitudinal fold line defined between a first side panel (120A) and a second side panel (120B). The depression (115) allows locating of the thumb of a user thereon while gripping the carton (100). The depression (115) also prevents slippage of the carton (100) while being gripped by the user.
A fitment hole (110) is configured on the first top panel (130A) by punching method or otherwise defined at a predetermined location on the first top panel (130A).
As shown in Figure 13, the fitment unit, consisting of a fitment spout (140A) and a cap closure (140B), is fitted through the hole (110) and attached to the carton (100). In an embodiment, the fitment spout (140A) includes a flange which is fused to the insides of the carton (100). In another embodiment, the fitment spout (140A) is welded to the insides of the top portion of the carton (100). As shown in Figure 12, a cap (140B) may be threadably and/or sealably engaged with the fitment unit.
In an operative configuration, once the base is formed and the fitment spout (140A) is attached to the carton, the carton (100) is placed beneath a nozzle (200) dispensing a fluid, as shown in Figure 12, to fill the carton (100) to a desired volume.
Only thereafter, is the formation of the top of the carton (100) initiated, as shown in Figure 14 through Figure 25.
The formation of the top of the carton is described as below:
The set of third fold lines configured on an operative top portion of the blank (105) is folded according to a predefined sequence such that the first top panel (130A) overlaps the second top panel (130B). Figure 15 shows the first top panel (130A), having the fitment and cap unit, about to be folded and pressed on the second top panel (130B). Figure 16 through Figure 19 shows the first top panel (130A) folded and pressed on top of the second top panel (130B). The top panel (130A, 130B) are attached to each other by heat sealing.
When pressed, the top portions (130) form a flat top of the carton (100) along with ear flaps (132A, 132B) extending out of the carton periphery (as seen in Figures 20 through 23). The ear flaps (132A, 132B) are affixed to the side body panels (125A, 125C) of the carton (100) to make the carton (100) as illustrated in Figure 20.
In yet another embodiment, the panels (125,130, 135) are attached by heat sealing or by other sealing methods.
The dispenser (10) further comprises a fitment unit mounted on the fitment hole (110) to facilitate fluid dispensation therethrough. The dispensing pump (150), as shown in Figure 2, is threadably attached to the fitment unit (140) to form the fluid dispenser (10). The pump (150) can be detached to allow a user to refill the dispenser (10) the cap (140B) may be removed from the fitment unit (140) prior to attachment of the pump (150) to the fitment unit (140).
In an embodiment, the second fold lines and the third fold lines include longitudinal, angular and transverse lines. In another embodiment, the section of the carton for the second top panel (130B) is configured to be folded along a transverse fold line to form a bi-layered second top panel (130B).
In an embodiment, the configuration of the first top panel (130A), when folded over the second top panel (130B), forms a multi-layered reinforced surface configured to resist deforming pumping forces in an operative configuration of the dispensing pump (150). More specifically, the multiple layers are defined by two layers formed by folding the second top panel (130B) over itself, and the third layer is formed by the first top panel (130A) overlapped on top of the second top panel (130B). The multilayered resisting platform formed by the top panels (130A, 130B) is not only an anti-deforming platform but is also resilient in nature as it dampens the deforming forces applied from the top, thereby maintaining the integrity of the carton (100). Resistance to deformation to the pumping forces is essential especially because the carton (100) is made of recyclable material that can easily crumple under such forces. Further, an air gap is defined by the panels (130A, 130B) that gives the resilient effect.
In an embodiment, the ratio of the overall width of the carton (100) to the distance between the free top edge of second top panel (130B) and the transverse fold line of the second top panel (130B) lies in the range of 0.45 to 0.53. In another embodiment, the dimension of the hole is half the overall width of the carton (100).
The result of such configuration and geometry of the fold lines and the dimensions of the hole (110) eliminates the need for configuring more than one fitment hole (110) on the top portion of the blank (105). More specifically, when the second top panel (130B) is folded along the transverse fold line, the folded second top panel (130B) does not come below the outline of the hole (110). As a result, there is no need for punching a hole on the second top panel (130B) as well. Further, any issues related to weakening of the substrate due to punching it is also reduced.
In an embodiment, the dispenser (10) is configured to dispense fluids or semi-fluids such as water, juices, milk and oil or slurries that include semi-viscous fluids such as soap slurries, adhesives, food pastes, gels, creams and lotions.
In an embodiment, the dispenser (10) is configured to be manufactured industrially in bulk amounts with the help of automatic machines.
In one embodiment, as shown in Figure 26 through Figure 28, the cap closure (140B) has a circular configuration. The fitment hole (110) has a circular configuration to complement the configuration of the cap closure (160).
In another embodiment, as shown in Figure 29 through Figure 31, the cap closure (140B) has an ovular configuration. The fitment hole (110) has an oval configuration to complement the configuration of the cap closure (160).
The present disclosure also envisages a process of making a fluid dispenser (10). The method comprises the steps:
a) preparing a blank (105) from a laminated recyclable substrate;
b) punching a fitment hole (110) at a predetermined location on an operative top portion of the blank (105);
