A closure assembly (38) includes a zipper (42) with the slider device. A method of using a package includes grasping a slider device and pushing a clip down to engage the clip against a portion of a zipper closure arrangement and then moving the slider device in a first direction while the clip squeezes the portion of the zipper closure arrangement to close the mouth .

Description

RECLOSABLE PACKAGE AND METHOD Technical Field

The present disclosure relates generally to closure arrangements packages, and, in particular, to a closure arrangement for recloseable tamper-evident packages, and methods of using tamper-evident packages.

Background

Reclosable packages are convenient because they can be closed and sealed to preserve and contain the enclosed contents. Reclosable packages are also advantageous because they may be opened and closed multiple times. However, in certain applications such as where it is desired to maintain the security and integrity of the contents of the package, it may be desired that a reclosable package be capable of being opened and closed multiple times, and also be capable of being closed in such a way that it cannot be readily opened again without providing an indication that it has been opened or tampered with, hi this way, the package is tamper-evident, such that an indication, such as a visual indication, is apparent if the package is opened after having been closed in such a way to prevent re-opening without providing an indication of tampering. For example, it may be desired to place evidence for use in a legal proceeding in a package. This may require opening and closing the package multiple times to deposit contents into the package, and when it is desired that the contents no longer be accessed, then closing the package in a manner that prevents the evidence contained within from being accessed or tampered without an indication being provided. Similarly, it may be desired to place cash or financial instruments in a package where the package is capable of being opened and closed multiple times before being closed in a manner that provides an indication if the contents are later accessed. Other applications for tamper-evident packages exist.

Consequently, a need exists for a package that can be opened and closed multiple times, and can be closed in such a way that an indication is provided if the package is re-opened. Summary

In one aspect, there is disclosed a slider device for use with a zipper closure arrangement for a recloseable package that has a top wall, a first sidewall depending from the top wall, and a second sidewall depending from the top wall. Together, the top wall, first sidewall, and second sidewall define a cavity adapted to receive the zipper closure arrangement. The slider device also includes a clip that is secured to at least one of the top wall, first sidewall, and second sidewall. The clip is moveable from a first, inoperative position to a second position, where the second position includes the clip being oriented to operatively engage the zipper closure arrangement.

Detailed Description

The present invention is believed to be applicable to a variety of packaging arrangements. The invention has been found to be particularly advantageous for use in sealing mechanisms for polymeric packages. An appreciation of various aspects of the invention is best gained through a discussion of an application example for such a packaging arrangement.

Figure 1 illustrates a package 20, which includes a first panel section 22 and second, opposed, panel section 24, typically made from a flexible, polymeric film. For some manufacturing applications, the first and second panel sections 22, 24 are heat-sealed together along two edges 26, 28 and meet at a fold line in order to form a three-edged containment section for a product within the interior 30 of the package 20. The fold line comprises the bottom edge 32. Alternatively, two separate panel sections 22, 24 of polymeric film may be used and heat-sealed together along the two edges 26, 28 and at the bottom 32. Together, panel sections 22, 24 comprise a surrounding wall 34 that defines the package interior 30. Access is provided to the interior 30 of the package 20 through a mouth 36. A closure assembly 38 is part of package 20 adjacent to mouth 36. Figure 2 illustrates an example closure assembly 38 constructed in accordance with the present disclosure. Closure assembly 38 comprises a slider device 40 and a zipper closure arrangement 42. Closure assembly 38 is shown in Figure 1 attached to surrounding wall 34 along mouth 36. For example, closure assembly 38 may be heat sealed to surrounding wall 34. Other methods of attachment are possible.

Zipper closure arrangement 42 includes a first zipper profile 44 defining a first closure 46 and a second zipper profile 48 defining a second closure 50. First closure 46 is constructed and arranged to selectively interlock. Many embodiments of closure 46 are useable. One embodiment of closure 46 is a reclosable closure 46 shown in Figure 9. In the embodiment shown in Figure 9, reclosable closure 46 comprises first and second opposing surfaces 52, 54. Attached to first opposing surface 52 is a first hooked profile member 56. Attached to the second opposing surface 54 is a second hooked profile member 58. Specifically, in the particular embodiment shown, the first and second hooked profile members 56, 58 have a J- shaped cross section.

In the specific embodiment shown, the reclosable closure further includes a first closure post 60 attached to first opposing surface 52 adjacent to the first hooked profile member 56. The first closure post 60 and first hooked profile member 56 form a gap 61 along first surface 52 that is configured to receive second hooked profile member 58 within gap 61. First and second hooked profile members 56, 58 are constructed and arranged to selectively interlock and separate. Specifically, an end region 62 of the first hooked profile member 56 engages with an opposing end region 64 of the second hooked profile member 58 to interlock the first and second hooked profile members 56, 58. To separate the first and second profile members 56, 58, sufficient force must be applied to closure 46 in a separating direction to cause first hooked profile member 56 and second hooked profile member 58 to deform and to slide out of contact. In some embodiments, a slider device is used to separate the members 56, 58, as described further below. Second closure 50 is also constructed and arranged to selectively interlock.

Many embodiments of closure 50 are useable. Closure 50 may be proximate to first reclosable closure 46 along first and second opposing surfaces 52, 54. In one embodiment, closure 50 may be a closure constructed in accordance with the embodiment depicted in Figure 9. In another embodiment, closure 50 is a tamper- evident closure that includes a tamper-evident structure to provide a signal when closure 50 has been interlocked and then separated at least once after being interlocked. An embodiment of a tamper-evident closure is depicted in Figure 10. In reference now to Figure 10, closure 50 includes a first zipper profile 66 defining a male profile member 68 and a second zipper profile 70 defining a female profile member 72. Male profile member 68 and female profile member 72 are constructed and arranged to selectively interlock. The male profile member 68 includes a head 74, having a wedge-shaped forward portion 76 and a straight rearward portion 78, and a stem 80 connecting the head 74 to the remaining portion of the first zipper profile 66. Still in reference to Figure 10, female member 72 comprises first and second arms 82, 84 that form a receiving void 86 sized to receive the forward portion 76 of head 74 of male member 68. Each of the arms 82, 84 of female member 72 includes fingers 88, 90 extending into void 86 to engage with rearward portion 78 of head 74 when head 74 is oriented in the void 86 of the female member 72.

In Figure 10, second closure 50 also includes first and second posts 92, 94 on first zipper profile 66, where the first post 92 is adjacent to and against the first arm 82 of female member 72, and the second post 94 is adjacent to and against the second arm 84 of female member 72 when the male member 68 is operably oriented in the female profile member 72. Stem 80 is frangible, such that a sufficient force applied in a separating direction to second closure 50 will cause stem 80 to break before male profile member 68 disengages from female profile member 72. The breaking of stem 80 separates head 74 from the remaining portion of first zipper profile 66, thereby providing an indication that the second closure 50 has been tampered with.

Closure assembly 38 includes a slider device 40. Slider device 40 is oriented to slide along the zipper closure arrangement 42 and is constructed to selectively squeeze one or more of first and second closures 46, 50. Many embodiments of slider device 40 are usable. A perspective view of one useable embodiment of a slider device 40 is shown in Figure 3. In the embodiment depicted in Figure 3, slider device 40 comprises a top wall 96, a first side wall 98 depending from top wall 96, and a second side wall 100 depending from top wall 96. Together, the top wall 96, first side wall 98, and second side wall 100 define a cavity 102 to operatively receive a zipper closure arrangement 42. Top wall 96 comprises an exterior surface 104 and an interior surface 106. Interior surface 106 is apparent in Figure 5.

Slider device 40 also comprises a clip 108 that is movable from a first, inoperative position to a second position. By "inoperative," it is meant that when in the first position, the clip 108 does not affect the operation of the slider device 40 relative to the zipper closure arrangement 42. Many embodiments of clip 108 are possible. A perspective view of one embodiment of clip 108 is shown in Figure 3. In the embodiment depicted in Figure 3, clip 108 is secured to at least one of the top wall 96, first side wall 98, and second side wall 100. In the embodiment shown in Figure 3, clip 108 includes a first wall 110, a first leg 112 depending from the first wall 110, and a second leg 114 depending from the first wall 110. The embodiment shown in Figure 3 depicts the clip 108 secured to the top wall 96. A living hinge 116 is depicted in this embodiment as securing the top wall 96 of the slider device 40 to the clip first wall 110. In the embodiment shown, top wall 96 of slider device 40 includes an aperture or opening 118 extending through top wall 96. Opening 118 is sized or dimensioned to allow the first and second legs 112, 114 of clip 108 to move through the cavity 102. First sidewall 98 of slider device 40 defines a first groove 134 sized to receive first leg 112 of clip 108. Second sidewall 100 of slider device 40 defines a second groove 136 sized to receive second leg 114 of clip 108.

Clip 108 is moveable from a first position, as shown in Figure 3, wherein the clip 108 is inoperative, to a second position, as shown in Figure 5, wherein the clip 108 is operatively oriented to engage the zipper closure arrangement 42. In the embodiment shown in Figure 3, in the first position of clip 108, the first and second legs 112, 114 are outside of opening 118, and the clip first wall 110 is angled relative to the top wall 96. As shown in Figure 4, when the clip 108 is in the second position, the first and second legs 112, 114 are at least partially inside of cavity 102. In particular, in the illustrated embodiment, the first and second legs 112, 114 are substantially all the way inside of cavity 102, and the clip first wall 110 is against top wall 96. Clip 108 is brought to the second position by moving clip 108 through opening 118 in top wall 96.

In some embodiments, slider device 40 includes a plow or splitter 120. Splitter 120 is constructed and arranged to at least partially separate the zipper closure arrangement 42 when the slider device 40 is slid along the zipper closure arrangement 42. One embodiment of a splitter 120 is depicted in Figure 5. The depicted splitter 120 depends from interior surface 106 of top wall 96, and is generally wedge-shaped. Splitter 120 is characterized by a splitter depth 121, defined as the distance that splitter 120 protrudes away from surface interior surface 106. Splitter depth 121 is generally not greater than the distance from top surface 138 of zipper closure arrangement 42 to the uppermost hooked profile member, such as hooked profile member 56.

In use, as the slider device 40 is slid or moved in an opening direction A (Figure 1), the splitter 120 urges the first hooked profile member 56 and second hooked profile member 58 (Figure 9) to deform and move out of engagement, causing the first closure 46 to unmate and open. In the embodiment depicted in Figure 9, splitter 120 contacts first and second opposing surfaces 52, 54 associated with first closure 46, so that motion of splitter 120 in an opening direction causes a separating force to be applied to opposing surfaces 52, 54. This separating force is transmitted through surface 52 to the first hooked profile member 56, and through surface 54 to second hooked profile member 58, causing each hooked profile member 56, 58 to deform and move out of engagement.

When the slider device 40 is slid along the zipper closure arrangement 42, splitter 120 does not operatively affect the second closure 50. In the embodiment of the zipper closure arrangement 42 depicted in Figure 8, surfaces 52, 54 of zipper closure arrangement 42 are sufficiently flexible that the separating force applied to them by splitter 120 near top surface 138 is significantly transmitted to first closure 46 but is not significantly transmitted to second closure 50.

Referring now to the embodiment of slider device 40 depicted in Figure 6, the first and second sidewalls 98, 100 of slider device 40 define a first width 122 therebetween to define a zipper squeezing region 124. The first width 122 is sized to cause the first and second sidewalls 98, 100 to squeeze at least a portion of the zipper closure arrangement 42. For example, in certain embodiments, the zipper squeezing region 124 is sized to cause the first and second sidewalls 98, 100 to squeeze first closure 46 of zipper closure arrangement 42 to cause first hooked profile member 56 and second hooked profile member 58 to interlock. First and second sidewalls 98, 100 also define a second width 126 therebetween to define a zipper non-squeezing region 128. Second width 126 is typically greater than first width 124. Furthermore, in the embodiment shown in Figure 6, the first and second sidewalls 98, 100 each has a hook construction 130, 132 at an end remote from the top wall 96. Zipper non-squeezing region 128 is between each hook construction 130, 132 and the zipper squeezing region 124.

Slider device 40 is configured to engage with zipper closure arrangement 42. Referring to the particular embodiment depicted in Figure 8, zipper closure arrangement 42 includes end or top surfaces 138, a first region 140 corresponding to first closure 46, a second region 142 corresponding to second closure 50, and package-side or bottom surfaces 144. In one embodiment, the second region 142 projects outwardly relative to the first region 140. hi the embodiment shown, the bottom surfaces 144 intersect with an outer portion 146 of the zipper closure arrangement 42 to define projecting corners 148. The corners 148 and the bottom surfaces 144 together result in rails 150 that are used for retaining the slider device 40 in sliding relation on the zipper closure arrangement 42.

In use, interior surface 102 of slider 40 engages with and slides along top surfaces 138 of zipper closure arrangement 42. Zipper squeezing region 124 engages with and slides along first region 140, and zipper non-squeezing region 128 engages with and slides along second region 142. Zipper squeezing region 124 generally contacts first region 140 and applies a compression load or squeezing force to first closure 46. Zipper non-squeezing region 128 generally provides a clearance with second region 142 or makes light contact with second region 142, such that zipper non-squeezing region 128 does not cause significant squeezing force to be applied to second closure 50. Hook construction 130, 132 engages with and slides along rails 150.

Referring to Figures 1 and 2, when clip 108 is in the first position, engaging the slider device 40 by moving it transversely in a first direction B (Figure 1) across the zipper closure arrangement 42 causes a squeezing pressure to be applied by zipper squeezing region 124 to first closure 46. In one embodiment, the squeezing pressure causes first hooked profile member 56 to engage with second hooked profile member 58, causing first closure 46 to be closed. Subsequently, engaging slider device 40 by moving it transversely in a second direction (A, Figure 1), reverse of the first direction, causes splitter 120 to engage with first and second opposing surface 52, 54 of first closure 46 and apply a disassembling force to first and second hooked profile members 56, 58, causing first closure 46 to be opened. While the clip 108 is in the first position, no squeezing pressure is applied to the second closure 50, and the male and female profile members 66, 70 are unaffected.

When clip 108 is moved to the second position (Figure 4), engaging the slider device 40 by moving it transversely in a first direction (B) across the zipper closure arrangement 42 causes both a first squeezing pressure to be applied by zipper squeezing region 124 to first closure 46 and a second squeezing pressure to be applied by first and second legs 112, 114 of clip 108 to second closure 50.

Specifically, the legs 112, 114 engage the second region 142. In one embodiment, the first squeezing pressure causes first hooked profile member 56 to engage with second hooked profile member 58, causing first closure 46 to be closed. The second squeezing pressure causes male profile member 66 and female profile member 70 to engage and interlock, causing second closure 50 to be closed. Subsequently, engaging slider device 40 by moving it transversely in a second direction (A, Figure 1), reverse of the first direction, causes splitter 120 to engage with first and second opposing surfaces 52, 54 of first closure 46 and apply a disassembling force to first and second hooked profile members 56, 58, causing first closure 46 to be opened. However, because of the configuration of second closure 50, for example by being sufficiently remote from first closure 46, engaging slider device 120 in the second direction does not cause a sufficient force to be applied to second closure 50 to cause it to be opened. Accordingly, once the male and female profile members 66, 70 of the second closure 50 are engaged and interlocked, further motion of slider device 40 will not cause second closure 50 to open.

To open second closure 50, it is necessary to apply force in a separating direction to second closure 50, such as by manually spreading zipper closure arrangement 42. When applying a tensile load or separating force to second closure 50, the amount of force required to disengage male profile member 66 from female profile member 70 is greater than the amount of force required to break male profile member 66 at neck 80. Thus, applying a sufficient separating force will break male profile member 66 at neck 80, releasing the connection between male profile member 66 and female profile member 70, and causing second closure 50 to be opened. However, the broken male profile member 66 will provide an indication that the package 10 has been opened at least once after the second closure 50 has been closed, providing evidence of tampering.

Zipper closure arrangement 42 typically comprises a polymeric material. Alternatively, as shown in Figure 7, zipper closure arrangement 42 may comprise a plurality of materials. For example, the first closure 46 of zipper closure arrangement may comprise a first material, such as polyethylene, and the second closure 50 of zipper closure arrangement 42 may comprise a second material, such as polypropylene.

A method of using a package such as package 20 is provided. The package 20 includes a package surrounding wall 34 defining an interior volume 30, a mouth 36, and a closure assembly 38 oriented at the mouth 36. Closure assembly 38 includes a zipper closure arrangement 42. In one embodiment, the method of using a package includes grasping a slider device such as slider device 40 and pushing a clip such as clip 108 down toward the slider device 40, and moving the slider device 40 in a first direction while the clip 108 squeezes a portion of the zipper closure arrangement 42 to close the mouth 36. In the embodiment of closure assembly 38 depicted in Figure 2, pushing clip 108 down causes first and second legs 112, 114 of clip 108 to engage against a portion of zipper closure arrangement 42, such as second region 142 associated with second closure 50. Slider device 40 is moved in a first direction along zipper closure arrangement 42, and in doing so, legs 112, 114 of clip 108 apply a squeezing force to second region 142, typically causing male profile member 66 to interlock with female profile member 70. When male profile member is interlocked with female profile member 70, the second closure 50 cannot be opened without breaking a portion of the second closure 50. The method may also include applying a separating force to second closure 50 so that a portion of the second closure 50 breaks, allowing access to the interior 30 of package 20.

The method of using a package also includes a step, before the step of grasping a slider device and pushing a clip down, where the earlier step includes grasping a slider device and moving the slider device in a first direction to squeeze only a portion of the zipper closure and releasably close the mouth. For example, where the clip 108 is not pushed down toward top face 96 of the slider device 40, but rather is removed from opening 118 and in an inoperative position and slider device 40 is moved in a first direction along zipper closure arrangement 42, then first and second sidewalls 98, 100 of slider device 40 apply a squeezing force only to first region 140.
