Embodiments of the present disclosure generally relate to the field of collation shrink films. More specifically, embodiments of the disclosure relate to a perforated top panel of a shrink-wrapped bottle pack.
Collation shrink films are films that are wrapped around one or more objects to be packaged and shrunk to keep the objects together. The most common use of these films is in the packaging of multiple containers, such as bottles containing beverages, food, and the like. The wrapping process generally involves a shrink oven or a shrink tunnel wherein the film and the containers covered by the film are briefly heated to cause the shrink-wrapping to occur. The plastic film then collapses around the containers and holds the units in place.
Films that are used as collation shrink films generally possess properties that make them commercially feasible. For example, films much exhibit good shrinkage, as well as possess excellent strength after shrinkage, referred to as load retention resistance. Further, films must resist puncture and must not be sticky so as to inhibit the film sticking to the packaged containers. Further, in some instances, the collation shrink films are cut during the wrapping process so amenability to cutting is important.
Sealing properties are also important. In some cases, during the wrapping process, the two sides of the film are passed around the object being wrapped and are contacted, typically underneath the product being wrapped. These two film edges must be sealed, and the seal strength needs to be high. Since the whole packaged ensemble is often carried simply by grabbing hold of the packaging film, the seal strength must ideally be strong enough to hold the weight of the packaged containers.
Systems and methods for application identification in accordance with embodiments of the invention are disclosed. In one embodiment, a perforated top panel is disposed in a shrink-wrapped bottle pack for containing water bottles, the perforated top panel including an easy-open panel, and a semi-circular portion disposed at a terminal end of the easy-open panel.
In a further embodiment, the easy-open panel is partially bordered by an alternating series of cuts and lands.
In another embodiment, the alternating series of cuts and lands are configured to allow the easy-open panel to tear away from the top panel upon being pulled by a practitioner.
In a still further embodiment, each of the cuts has a length of substantially 0.125 inches and each of the lands has a length of substantially 0.250 inches.
In still another embodiment, each of the lands has a length ranging between substantially 0.250 inches and substantially 0.375 inches.
In yet another embodiment, each of the cuts has a length of substantially 0.125 inches and each of the lands has a length of substantially 0.3125 inches.
In a further embodiment again, the easy-open panel includes a parallel portion that extends to a tapered portion that terminates at the semi-circular portion.
In another embodiment again, the parallel portion has a width of 7.5 inches and is disposed substantially 2.25 inches from opposite sides of the bottle pack.
In a further additional embodiment, the semi-circular portion is configured to be grasped and pulled to separate the tapered portion and the parallel portion from the top panel and thus expose the water bottles.
In another additional embodiment, the tapered portion begins at a distance of about 4.75 inches from the semi-circular portion, opposite sides of the tapered portion each approaching the midline of the easy-open panel by a distance of substantially 3.75 inches before terminating at the semi-circular portion.
In a still yet further embodiment, the tapered portion includes one or more portions that are increasingly tapered toward the semi-circular portion.
In still yet another embodiment, the tapered portion includes a first tapered portion that beings at about 5.125 inches from the semi-circular portion, each of the opposite sides of the first tapered portion narrowing by substantially 0.25 inches.
In a still further embodiment again, the first tapered portion transitions to a second tapered portion at about 3.625 inches from the semi-circular portion, opposite sides of the second tapered portion each narrowing by about 0.75 inches.
In still another embodiment again, the second tapered portion transitions to a third tapered portion at about 1.5 inches from the semi-circular portion, opposite sides of the third tapered portion narrowing by about 1.625 inches before terminating at the semi-circular portion.
In a still further additional embodiment, the semi-circular portion includes a cutout portion of the top panel having a radius of substantially 0.53 inches and being disposed roughly 1.5 inches from a side portion of the bottle pack.
In still another additional embodiment, the semi-circular portion is centrally disposed along a midline of the easy-open panel.
In a yet further embodiment again, the parallel portion is bordered on opposite sides by parallel perforations.
In yet another embodiment again, the parallel portion has a width and a length suitable to allow access to the water bottles once the easy-open panel is torn open.
In a yet further additional embodiment, the parallel portion has a width of 6.25 inches and is disposed substantially 1.625 inches from opposite sides of the shrink-wrapped bottle pack.
In yet another additional embodiment, the length of the parallel portion extends substantially 12 inches from the side of the bottle pack nearest the semi-circular portion.
In many embodiments, a method for a perforated top panel disposed in a shrink-wrapped bottle pack containing water bottles includes shrink-wrapping a multiplicity of water bottles to form a pack of the water bottles, perforating an easy-open panel in a top panel including the shrink-wrapped bottle pack, and forming a semi-circular portion at a terminal end of the easy-open panel.
In a further additional embodiment again, forming the semi-circular portion includes cutting the semi-circular portion into the shrink-wrapping by way of a blade or a laser coder.
In another additional embodiment again, perforating includes forming cuts in the shrink-wrapping by way of a blade or a laser coder.
In a still yet further embodiment again, forming includes for fling 0.125 inch-long cuts in the shrink-wrapping, adjacent cuts being separated by lands ranging between substantially 0.250 inches and substantially 0.375 inches.
In still yet another embodiment again, perforating includes including a parallel portion and a tapered portion including the easy-open panel, the tapered portion terminating at the semi-circular portion.
The drawings refer to embodiments of the present disclosure in which:
While the present disclosure is subject to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will herein be described in detail. The invention should be understood to not be limited to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure.
A drawback to conventional collation shrink films, however, is they are often strong enough to hinder a consumer opening shrink-wrapped packages. A knife or scissors generally are required to cut open the shrink-wrapped package. In absence of such a tool, the consumer is left with pulling, ripping and tearing at the film to access the containers within the package. Embodiment presented herein correct these drawbacks and provide consumers with shrink-wrapped beverage packages that are easy to open without falling apart beforehand.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be apparent, however, to one of ordinary skill in the art that the invention disclosed herein may be practiced without these specific details. In other instances, specific numeric references such as “first panel,” may be made. However, the specific numeric reference should not be interpreted as a literal sequential order but rather interpreted that the “first panel” is different from a “second panel.” Thus, the specific details set forth are merely exemplary. The specific details may be varied from and still be contemplated to be within the spirit and scope of the present disclosure. The term “coupled” is defined as meaning connected either directly to the component or indirectly to the component through another component. Further, as used herein, the terms “about,” “approximately,” or “substantially” for any numerical values or ranges indicate a suitable dimensional tolerance that allows the part or collection of components to function for its intended purpose as described herein.
In general, the present disclosure provides a perforated pattern disposed on a top panel of a shrink-wrapped bottle pack configured to provide an easy-open feature for consumers. The perforated pattern may be applied after the bottle pack is shrink-wrapped. Further, the perforated pattern may be formed by way of various blades, or by way of one or more laser coders.
Both the perforation pattern and the shape of the easy-open panel are critical to the functionality of the perforated pattern. If the perforations, or “cuts,” or the distance between the cuts, called “lands,” is too large, the ease of opening may be adversely influenced. For example, if the perforation pattern is too aggressive there is risk that the easy-open feature may operate prematurely, whereas if the perforation pattern is too conservative the feature may be difficult to open and result in jagged edges on the film. The shape of the easy-open panel also is crucial to performance. Experimentation has demonstrated that a tapered configuration generally provides optimal results, as shown and described herein.
Turning specifically to the drawings,
With continuing reference to
The parallel portion 120 is bordered on opposite sides by parallel perforations (i.e., the cuts 112 and lands 116), as shown in
As mentioned hereinabove, the parallel portion 120 extends of a tapered portion 124 that terminates at the semi-circular portion 128. It is contemplated, however, that the tapered portion 124 may include one or more portions that are increasingly tapered toward the semi-circular portion 128. For example, in the illustrated embodiment of
As will be recognized, opposite sides of the first, second, and third tapered portions 136, 140, 144 approach the midline of the easy-open panel 108 with increasing degrees of taper. As shown in
The perforated top panel 164 comprises an easy-open panel 168 that is partially bordered by an alternating series of cuts 112 and lands 116. The series of cuts 112 and lands 116 are configured to allow the easy-open panel 168 to tear away from the top panel 164 upon being pulled by a practitioner. In the illustrated embodiment of
The easy-open panel 168 comprises a parallel portion 172 that extends to a tapered portion 176 that terminates at a semi-circular portion 180. As will be appreciated, a practitioner desiring access to the bottles 102 may grasp the semi-circular portion 180 and pull to separate the tapered portion 176 and the parallel portion 172 from the top panel 164 to expose the bottles 102. The semi-circular portion 180 is substantially similar to the semi-circular portion 128 and thus comprises a cutout portion of the top panel 164 having a radius of substantially 0.53 inches. Further, the semi-circular portion 180 may be disposed roughly 1.5 inches from a side portion of the bottle pack 160 and is centrally disposed along a midline of the easy-open panel 168.
The parallel portion 172 is bordered on opposite sides by parallel perforations, as shown in
The tapered portion 176 extends from the parallel portion 172 and terminates at the semi-circular portion 180. In the illustrated embodiment of
While the invention has been described in terms of particular variations and illustrative figures, those of ordinary skill in the art will recognize that the invention is not limited to the variations or figures described. In addition, where methods and steps described above indicate certain events occurring in certain order, those of ordinary skill in the art will recognize that the ordering of certain steps may be modified and that such modifications are in accordance with the variations of the invention. Additionally, certain of the steps may be performed concurrently in a parallel process when possible, as well as performed sequentially as described above. To the extent there are variations of the invention, which are within the spirit of the disclosure or equivalent to the inventions found in the claims, it is the intent that this patent will cover those variations as well. Therefore, the present disclosure is to be understood as not limited by the specific embodiments described herein, but only by scope of the appended claims.
