Definitions

  • the present invention generally relates to closure arrangements for polymer packages, such as, plastic bags.
  • the present invention relates to resealable closure mechanisms or zipper-type closures for resealable packages.
  • resealable containers to store or enclose various types of articles and materials. These packages may be used to store food products, non-food consumer goods, medical supplies, waste materials, and many other articles. Resealable packages are convenient in that they can be closed and resealed after the initial opening to preserve the enclosed contents. The need to locate a storage container for the unused portion of the products in the package is thus avoided. In some instances, providing products in resealable packages appreciably enhances the marketability of those products.
  • the slider device typically includes a separator or spreader-type structure at one end that opens a closure mechanism, having profiled elements or closure profiles, when the slider device travels in a first direction along the mechanism.
  • the sidewalls of the slider device are configured so that the sidewalls engage the closure profiles and progressively move them into engagement to close the resealable package when the slider device is moved along the closure mechanism in a direction opposite the first direction.
  • This slider device includes a housing of two convergent side walls having a central partition therebetween. The partition extends between the profile elements of profiles of the closure mechanism.
  • a further example of a slider device is shown in U.S. Patent No. 5,010,627 to Herrington.
  • This slider device includes a central partition that only extends between the upper flanges of the closure members while not penetrating between an interlocking part thereof.
  • a slider device for use with a resealable closure mechanism having a first closure profile and a second closure profile.
  • One preferred slider device includes a top wall; a spreader depending from the top wall, first and second sidewalls, first and second hook constructions; and a guide construction projecting beyond at least one of a first end and a second end of the first sidewall.
  • the guide construction includes first and second fingers, with at least one of: (a) the first finger projecting beyond the first end; and (b) the second finger projecting beyond the second end. In some embodiments, both: (a) the first finger projects beyond the first end of the first sidewall; and (b) the second finger projects beyond the second end of the first sidewall. In other embodiments, only one of the fingers projects beyond a respective end of the first sidewall.
  • the slider device further includes first and second standoffs in projection from the first and second sidewalls, respectively.
  • the disclosure also concerns a reclosable zipper arrangement.
  • the zipper arrangement includes a first closure profile defining a first shoulder and a second closure profile defining a second shoulder.
  • a slider device is provided with a spreader to separate the first and second closure profiles.
  • First and second hook constructions on the slider device slidably engage with the first and second shoulders of the first and second closure profiles, respectively.
  • a guide construction preferably projects beyond at least one of a first and second end of a sidewall of the slider device.
  • Flexible packages comprise a package surrounding wall having first and second side seals and a mouth therebetween.
  • a reclosable zipper is provided along the mouth for selective opening and closing of the mouth.
  • a slider device of the type characterized above is operably mounted on the package.
  • One preferred zipper includes first and second closure profiles defining first and second shoulders, respectively.
  • First and second hook constructions on the slider device are included for sliding along the first and second shoulders, respectively.
  • a guide construction is provided on the slider device.
  • Methods of using a resealable package include a step of moving a slider device along a mouth a first direction from a side seal of the resealable package until a projecting finger on the slider device engages a first side seal on the resealable package.
  • Packages and slider devices as described herein may be usable in this method.
  • FIG. 1 illustrates an example packaging arrangement in the form of a resealable, flexible package 110, for example, a polymeric package such as a plastic bag, having a resealable closure mechanism 114, for example, interlocking profiled elements, constructed in accordance with the present invention.
  • the flexible package 110 includes first and second opposed panel sections 116, 118, typically made from a flexible, polymeric, plastic film. With some manufacturing applications, the first and second panel sections 116, 118 are heat-sealed together along two side edges 120, 122 and meet at a fold line 123 in order to form a three-edged containment section for a product within an interior 124 of the package 110.
  • the fold line 123 comprises the bottom edge 125 of the package 110.
  • two separate panel sections 116, 118 of plastic film may be used and heat-sealed together along the two side edges 120, 122 and at the bottom edge 125.
  • Access is provided to the interior 124 of the package 110 through a mouth 126 at a top edge 127 of the package.
  • the mouth 126 extends the width of the package 110.
  • the resealable closure mechanism 114 is illustrated in FIG. 1 at the mouth 126 of the flexible package 110. In the embodiment shown, the resealable closure mechanism 114 extends the width of the mouth 126. Alternatively, the closure mechanism 114 could be positioned on the package 110 at a location different from the mouth 126 of the package 110, depending on the application needs for the package 110.
  • the resealable closure mechanism 114 can be one of a variety of closure mechanisms. In the particular embodiment illustrated in FIG. 2, the resealable closure mechanism 114 is shown in the specific form of a zipper-type closure mechanism.
  • the zipper-type closure mechanism is not a rolling action type zipper. That is, preferably the closure is not one that closes by movement from a 6 o'clock position to a 12 o'clock position. It is noted, however, that slider devices 150 of the types described herein are usable with rolling action type zippers. Preferred zipper-type closure mechanisms described herein close by movement from a 9 o'clock to a 3 o'clock position.
  • the zipper-type closure mechanism in FIG. 2 is an illustration of one example of a closure mechanism 114.
  • the closure mechanism 114 includes an elongated first closure profile 130 and an elongated second closure profile 131.
  • the closure profiles 130, 131 are manufactured separately from each other.
  • the preferred first closure profile 130 depicted includes a sealing flange or bonding strip 132, a base strip 133, a first closure member 134, first and second guide posts 136, 137, and an upper flange 139.
  • the closure member 134 extends from the base strip 133 by way of a stem 134a and is generally projecting from the base strip 133.
  • a hook or catch 140 At a free end of the stem 134a (the tip of the closure member 134) is a hook or catch 140.
  • the guide posts 136, 137 also extend from the base strip 133 and are generally projecting from the base strip 133.
  • the guide posts 136, 137 aid in holding the closure mechanism 114 closed and in aligning the first closure profile 130 with the second closure profile 131 for interlocking.
  • the bonding strip 132 depends or extends downward from the second guide post 137 and can be attached to a first panel section, such as the first panel section 116 of the package 110 of FIG. 1 at region 135 (FIG. 1).
  • a first shoulder 138 is defined by the intersection of the base strip 133 and bonding strip 132. In the example illustrated, the bonding strip 132 is spaced a distance laterally from the base strip 133 to define a comer forming the shoulder 138.
  • the upper flange 139 extends upwardly from the base strip 133 and first guide post 136.
  • the preferred second closure profile 131 depicted includes a bonding strip 142, a base strip 143, a first closure member 144, a guide post 146, and an upper flange 147.
  • the closure member 144 extends from the base strip 143 by way of a stem 144a and is generally projecting from the base strip 143.
  • a hook or catch 149 At a free end of the stem 144a (or tip of the closure member 144) is a hook or catch 149.
  • the guide post 146 also extends from the base strip 143 and is generally projecting from the base strip 143. The guide post 146 aids in holding the closure mechanism 114 closed and aids in aligning the second closure profile 131 with the first closure profile 130 for interlocking.
  • the bonding strip 142 depends or extends downward from the guide post 146 and can be attached to a second panel section, such as the second panel section 118 of the package 110 of FIG. 1.
  • a shoulder 148 analogous to the shoulder 138, is formed at the comer of the bonding strip 142 and guide post 146.
  • the first and second closure profiles 130, 131 are designed to engage with one another to form the resealable closure mechanism 114.
  • the closure member 134 of the first closure profile 130 extends from the base strip 133 a first distance.
  • the closure member 144 of the second closure profile 131 also extends from the base strip 143 a first distance. These first distances that the closure members 134, 144 extend are sufficient to allow mechanical engagement, or interlocking, between the first closure member 134 of the first closure profile 130 and the first closure member 144 of the second closure profile 131.
  • the catches 140, 149 hook or engage each other.
  • the closure profiles 130, 131 are sealed together at their ends, such as regions 196, 198 of FIG.
  • the closure profiles 130, 131 are formed by two separate extrusions or through two separate openings of a common extrusion.
  • the resealable closure mechanism 114 is made of conventional materials, such as a polymeric, plastic material, for example, polyethylene or polypropylene.
  • the closure arrangement illustrated in FIG. 2 is manufactured using conventional extrusion and heat sealing techniques.
  • FIG. 1 note that there is a cutout or notch 128 formed in the upper flanges 139, 147 (FIG. 2) of the resealable closure mechanism 114.
  • the preferred notch 128 shown includes two straight edges or sides 129a, 129b, generally perpendicular to each other, and a side 129c that extends at, in a preferred embodiment, an oblique angle relative to side 129b.
  • oblique angle it is meant an angle that is not substantially perpendicular or straight.
  • the side 129a preferably is generally parallel to side edge 120, while the side 129b preferably is generally parallel to the bottom edge 125.
  • the side 129c can extend at an angle relative to side 129b of at least 30 degrees, typically between about 100-150 degrees, typically no greater than about 160 degrees, and in the preferred embodiment about 135 degrees.
  • the notch 128 serves as a "parking place" for a slider device 150 and also facilitates mounting the slider device 150 onto the resealable package 110 during initial assembly.
  • the edge 129a closest to the side seal 120 helps to create a stop member for the slider device 150.
  • the angle that the side 129c extends helps to reduce friction between the slider device 150 and the resealable closure mechanism 114, when the slider device 150 is being moved from the notch 128 to open the closure mechanism 114. This contributes to an easier opening, more convenient package 110.
  • the slider device 150 is provided to open and close the resealable closure mechanism 114. Attention is directed to FIGS. 3 and 4.
  • One preferred slider device 150 is illustrated in FIGS. 3 and 4 in perspective view and preferably comprises a one-piece unitary, molded plastic member with no moveable parts that are moveable with respect to one another.
  • the slider device 150 includes a housing 152 for slidably engaging the closure mechanism 114.
  • the housing 152 is movable between a closed position of the resealable package 110 when the housing 152 is adjacent the side edge 120 and an open position of the resealable package 110 when the housing 152 is adjacent the side edge 122.
  • FIG. 1 illustrates the resealable package 110 in an open position.
  • the housing 152 slides over the resealable closure mechanism 114 relative to the top edge 127 of the resealable package 110 to open and close the mouth 126.
  • the housing 152 is preferably a multi-sided container configured for engaging or locking onto or over the resealable closure mechanism 114.
  • the housing 152 includes a top wall 154.
  • top it is meant that in the orientation of the slider device 150 shown in FIG. 1, the wall 154 is oriented above the remaining portions of the housing 152. It should be understood, of course, that if the housing 152 is moved from the orientation shown in FIG. 1, the top wall 154 will not be in a top orientation.
  • the top wall 154 defines a first end 155 and an opposite second end 156.
  • the top wall 154 also defines an open aperture 158.
  • the open aperture 158 divides the top wall 154 between a first portion 160 and a second portion 161.
  • the first portion 160 generally comprises a flat, planar portion in extension from a periphery of the open aperture 158 to the edge defined by the first end 155.
  • the second portion 161 generally comprises a flat, planar portion in extension from a periphery of the open aperture 158 to the edge defined by the second end 156.
  • Each of the first and second portions 160, 161 defines a groove 163, 164 respectively.
  • the aperture 158 and grooves 163, 164 aid in providing a structure that may be more easily injection molded.
  • the housing 152 includes a separation structure for separating the first and second closure profiles 130, 131. That is, when the resealable closure mechanism 114 is in a closed state such that the closure members 134, 144 are interlocked, the separation structure will apply a force to wedge open and pull the closure members 134, 144 apart from each other.
  • the housing 152 includes a spreader 166 operating as a separation structure.
  • the spreader 166 in the preferred embodiment shown, extends or depends from the top wall 154.
  • the spreader 166 comprises first and second angled wedges 168, 169 separated by a gap 170 (FIG. 5) therebetween.
  • first and second wedges 168, 169 are angled toward each other, from the first end 155 of the slider device 150 to an opposite end of the wedges 168, 169, to form an overall triangle shaped spreader 166, in plan view, with an apex of the triangle pointing toward the second end 156 of the housing 152.
  • the gap 170 between the first wedge 168 and second wedge 169 helps to contribute to convenient use of the slider device 150.
  • the spreader 166 only extends partially in the resealable closure mechanism 114. More preferably, the spreader 166 only extends between the open flanges 139, 147 and does not penetrate the closure members 134, 144. This helps to reduce likelihood of leaks in the closure mechanism 114. In the preferred embodiment shown, the spreader 166 preferably extends about 0.125 inches from the first portion 160 of the top wall 154.
  • the preferred housing 152 shown also includes first and second sidewalls 172, 174.
  • each of the first and second sidewalls 172, 174 extends from and is cantilevered from the top wall 154 to form a slide channel 177 therebetween.
  • the first and second sidewalls 172, 174 are injection molded with the remaining parts of the housing 152.
  • the housing 152 comprises a single, unitary, integral piece of material with no additional materials welded, fastened, or bolted together.
  • the sidewalls 172, 174 can include texturization, such as ribs, 173, 175 to help improve gripping and handling by the user.
  • the housing 152 includes a system for permitting the housing 152 to slide along the resealable closure mechanism 114 without becoming disengaged from the resealable package 110.
  • the system of the slider housing 152 engages or interlocks with certain structure of the resealable closure mechanism 114.
  • the housing 152 has a first and a second hook construction 176, 178.
  • the first hook construction 176 preferably extends from the first sidewall 172 in a portion of the housing 152 that is under the open aperture 158.
  • the first hook construction 176 preferably includes a flange 180 in lateral extension from the first sidewall 172. Extending or projecting from flange 180 is a tip 182 oriented toward the top wall 154. As such, the tip 182, in combination with the flange 180, forms a hook or catch for slidable engagement with the shoulder 148 of the second closure profile 131.
  • the second hook construction 178 preferably includes a flange 184 in extension from the second sidewall 174 and in a region of the housing 152 below the open aperture 158.
  • a tip 186 projects or extends from flange 184 in a direction oriented toward the top wall 154.
  • the flange 184 and tip 186 cooperate to form a hook or catch for engaging in a slidable manner with the shoulder 138 of the first closure profile 130.
  • the first hook construction 176 is located closer to the top wall 154 than the second hook construction 178. This is generally because, in the embodiment shown, the second sidewall 174 is longer than the first sidewall 172.
  • FIGS. 14 and 15 depict alternate embodiments for hook constructions 176, 178 at 176' and 176".
  • the tip 182' has a smooth, rounded corner 182a.
  • the tip 182" has a bevel or chamfered corner 182a". It has been found that in certain applications, the alternate tips 182', 182" reduce friction and drag of the slider device 150 across the closure mechanism 114.
  • the first and second hook constructions 176, 178 each has circular, partial cavities 187, 188, respectively, formed therein. These cavities 187, 188 help facilitate convenient manufacturing techniques, such as injection molding.
  • the slider device 150 preferably includes a system for guiding the slider device 150 between the side edges 120, 122 (FIG. 1) and for preventing the slider device 150 from sliding off the edge of the package 110 (FIG. 1).
  • the system includes a guide construction 190 (FIG. 4).
  • the guide construction 190 shown is designed to project beyond the first and second ends 155, 156 of the top wall 154. This ensures that the guide construction 190 detects the regions of ultrasonic crushing 196, 198 before any other structure on the housing 152 engages the sides 120, 122 of the package 110.
  • the guide construction 190 depends from the top wall 154, but could depend from other portions of the housing 152 in other embodiments.
  • the guide construction 190 comprises first and second bumpers or elongate fingers 192, 194.
  • the first bumper or finger 192 preferably is molded as part of the housing 152 to extend a distance of at least about 0.06 inches (1.5 mm) beyond the first end 155 of the first portion 160.
  • the second bumper or finger 194 likewise is preferably molded as part of the housing 152 to extend a distance of at least 0.06 inches (1.5 mm) beyond the second end 156 of the second portion 161.
  • the first finger 192 will abut or engage side edge 129a and the region 196 to inhibit the housing 152 from sliding off of the resealable package 110.
  • the second finger 194 will abut or engage the region 198 to inhibit the housing 152 from sliding off of the resealable package 110.
  • the guide construction 190 helps to keep the housing 152 within the boundaries or periphery defined by the side edges 120 and 122. Further detail regarding this is explained in conjunction with FIGS. 8 and 9.
  • the slider housing 152 is shown in a position where the resealable closure mechanism 114 is closed.
  • the first finger 192 is shown engaged with the side edge 129a of the notch 128. In usual operation, the first finger 192 will stop when it engages the side edge 129a of the notch 128. In some circumstances, however, the first finger 192 may abut and engage the region 196 of ultrasonic crushing, depending on the configuration of the region 196 and the force used by the operator of the slider 150.
  • the housing 152 is shown in a position where the reclosable closure mechanism 114 is in an open position.
  • the second finger 194 of the guide construction 190 (FIG. 5) is illustrated as abutting the region 198 of ultrasonic crushing. Note that the abutment or engagement occurs either below the top edge 127 or even with the top edge 127.
  • the housing 152 includes a system for reducing drag. That is, the housing 152 is designed such that the surface area contact between the housing 152 and the resealable closure mechanism 114 is minimal.
  • the system includes first and second standoffs 201, 202.
  • the first standoff 201 preferably projects or extends from the first sidewall 172 in the form of a first pin or rod 203.
  • the second standoff 202 projects or extends from the second sidewall 174 in the form of a second pin or rod 204.
  • the first and second rods 203, 204 project at least about 0.0085 inches (0.22 mm) from their respective sidewalls 172, 174.
  • the first rod 203 extends the entire length between the bottom of the first sidewall 172 and the top wall 154.
  • the second rod 204 extends the entire length between the top wall 154 and the bottom edge of the second sidewall 174.
  • the standoffs 201, 202 slidably communicate with the first and second closure profiles 130, 131, respectively. Because of the projection and extension of the standoffs 201, 202 relative to the remaining portions of the housing 152, the amount of surface area contact or material inducing friction between the housing 152 and the resealable closure mechanism 114 is reduced relative to a housing construction that does not have standoffs 201, 202. This permits easier manipulation of the slider device 150 by the user.
  • one preferred technique for manufacturing the slider housing 152 is injection molding. While other methods are possible, injection molding is convenient and preferred. In addition, injection molding allows for ornamental features to be molded as part of the housing 152. As such, the resulting housing 152 illustrated in FIGS. 3 and 4 is distinctive, eye-catching, and attractive.
  • the package 110 can be formed by either a blown extrusion process or by using a pre-formed roll of film.
  • the film is folded in the form shown in FIG. 1.
  • the resealable closure mechanism 114 can be applied to the film panel sections 116, 117 by heat sealing the bonding strips 132, 142 to the film sections.
  • the notch 128 can be cut into the upper flanges 139, 147.
  • the side seals including the regions 196, 198 of ultrasonic crushing can be formed.
  • the housing 152 can then be mounted over the resealable closure mechanism 114 by sliding it onto the notch 128.
  • the notch 128 is formed twice as long as the length of the spreader 166. This is because when the slider housing 152 in moved into the closed position (FIG. 8), the widest part of the spreader 166 will be situated in the open area represented by the notch 128. As a result, the spreader 166 will not spread the walls of the closure mechanism 114 at this location. This ensures that when the slider housing 152 is moved all the way to the closed position, as shown in FIG. 8, the closure mechanism 114 will be completely closed and, even in the part of the closure mechanism 114 located under the separator 166, will not be spread or biased open.
  • the housing 152 is pressed onto the receivable closure mechanism 114 until the first and second hook constructions 176, 178 snap over the shoulders 138, 148, respectively, of the closure profiles 130, 131, respectively.
  • the slider device 150 is slid relative to the resealable closure mechanism 114 from the closed position of FIG. 8 to the open position of FIG. 9.
  • the spreader 166 forces the closure members 134, 144 apart from each other.
  • the spreader 166 is spaced between the upper flanges 139, 147 of the profile members 130, 131 and opens the mouth 126 as the slider housing 152 is moved along the resealable package 110 in the direction toward where the triangle of spreader 166 "points.”
  • the opening happens because the triangular shape of the spreader 166 operates as a cam to force the profile members 130, 131 apart, and thus to disengage the interlocking members 134, 144.
  • the slider housing 152 is moved relative to the resealable closure mechanism 114 from the position of FIG. 9 to the position of FIG. 8.
  • the closing happens because the slide channel 177 between the sidewalls 172, 174 is narrower at end 156 (the end away or remote from the spreader 166) and is wider at the end 155 (the end near or adjacent to the spreader 166).
  • the spreader 166 does not depend very far downwardly into the closure mechanism 114, and it never actually passes between the interlocking members 134, 144. Thus, this helps to prevent leaks in the closure mechanism 114, when the slider device 150 is in the closed position.
  • the slider device housing 152 may be moved until the first finger 192 abuts the side seal or region of ultrasonic crushing 196 or, in some embodiments, the edge 129a of the notch 128.

  • FIGS. 16 and 17 show a slider device 350 in perspective views.
  • the slider device 350 is generally constructed analogously to the embodiment of FIGS. 3-9, but with some modifications, to be discussed below.
  • the slider device 350 has a housing 352, which includes a top wall 354 having a first end 355 and a second end 356.
  • the top wall 354 has an open aperture 358, which divides the top wall 354 into a first portion 360 and a second portion 361. Note that the first portion 360 and second portion 361 of the top wall 354 are smooth and planar. Note the absence of grooves in top wall 354.
  • the slider device 350 includes a plow 366. Attention is directed to FIG. 18.

  • the housing 352 also includes a first sidewall 372 with a texturized surface to enhance gripping, for example ribs 373.
  • the housing 352 also has a second sidewall 374 with ribs 375.
  • the first sidewall 372 has a first end 372a that is adjacent to the plow 366 and an opposite, second end 372b.
  • the second sidewall 374 has a first end 374a adjacent to the plow 366 and a second, opposite end 374b.
  • the slider 350 includes the first hook construction 376 and a second hook construction 378.
  • the first hook construction 376 includes a flange 380 in extension from the first sidewall 372. Note that in this embodiment, there are no tips or projections extending from the flange 380.
  • the second hook construction 378 has a flange 384 extending from the second sidewall 374. There is no tip or any other extension projecting from the flange 384.
  • the slider device 350 includes a system for guiding the slider device 350 between the side edges 420, 422 (FIG. 23) and for preventing the slider device 350 from sliding off of the edge of the package 410 (FIG. 23).
  • the system includes a guide construction 390 (FIG. 18).
  • the guide construction 390 of this embodiment differs somewhat from the embodiment of FIGS. 3-9.
  • the guide construction 390 shown is constructed and arranged to detect regions of ultrasonic crushing 396, 398 (FIGS. 22 and 23) before any other structure on the housing 352 engages sides 420, 422 (FIGS. 22 and 23) of package 410.
  • the guide construction 390 depends or extends from the top wall 354, but could depend from other portions of the housing 352 in other embodiments.
  • the guide construction 390 comprises first and second bumpers or elongate fingers 392, 394 (FIGS. 18 and 19).
  • the first finger 392 preferably is molded as part of the housing 352. In this embodiment, the first finger 392 extends or projects a distance beyond a recesses portion 397 (FIG. 19) of the top wall 354, but is otherwise even with the first end 355 of the top wall 354. This construction is preferred because, among other reasons, during the assembly process, the slider housings 352 do not jam or stack on top of each other. As can be seen in FIG. 18, the first finger 392 extends or projects a distance beyond the first end 372a of the first sidewall 372. Likewise, the first finger 392 extends or projects beyond the first end 374a of the second sidewall 374.
  • the first finger 392 is constructed and arranged to extend or dig into the region of ultrasonic crushing 396, if the slider housing 352 is moved past a notch 428 (FIG. 22).

  • Side edge 429c is angled at least about 10°, typically about 20-70°, and preferably about 45° from a line parallel to a top edge 427 of package 410.
  • the angled side edge 429c extends at an angle of at least about 10°, typically about 20-70°, and preferably about 45° from a line parallel to the side edge 420.
  • side edge 429b is angled slightly from the horizontal.
  • the inside edges 368a and 369a (FIG. 18) of the first and second wedges 368, 369 will engage the side edges 429c of the notch 428. This will act as a stop member and provide a tactile indication that the housing 352 is "parked” or in a closed position. If, however, the slider housing 352 is forcibly moved toward the side edge 420, then the first finger 392 will engage or bump into the region of ultrasonic crushing 396.
  • the shape of the first finger 392 allows the first finger 392 to engage the region of ultrasonic crushing 396 without having other portions of the slider housing 352 from engaging the region of ultrasonic crushing 396. This also stops the slider housing 352 from being pushed off the end of the package 410.
  • the first finger 392 in cross section has a first portion 412 that extends from the top wall 354, and preferably, is normal to the top wall 354.
  • the preferred embodiment has the first portion 412 being straight and generally parallel to the first end 374a of the second sidewall 374. Extending from the first portion 412 is an angled edge 413. In preferred embodiments, the angle between the first portion 412 and the angled edge 413 is at least about 90°, typically about 120-170°, and in preferred embodiments about 150°.
  • Edge 414 is generally parallel to the top wall 354.
  • the angled edge 413 and edge 414 cooperate to form a nose 415 of the first finger 392.
  • the nose 415 is the structure that will, in preferred embodiments, engage the region of ultrasonic crushing 396, if the slider housing 352 is forced all of the way it can be toward the side edge 420 and into the region of ultrasonic crushing 396.
  • the angle between edge 413 and edge 414 to form nose 415 is at least about 15°, typically about 30-80°, and in preferred embodiments about 60°.
  • the second finger 394 is illustrated in cross section. Note that the second finger 394, in preferred arrangements, at its outermost portion or nose 416 extends about even with the second ends 372b and 374b (FIG. 18). The nose 416 also extends about even with the second 356 of the top wall 354.
  • the second finger 394 does extend or project beyond the recessed region 417 of the top wall 354. This construction is preferred because, among other reasons, during the assembly process, the slider housings 352 do not jam or stack on top of each other. While a variety embodiments for the second finger 394 are contemplated, in the particular embodiment shown in FIG. 20, the second finger 394 has a first portion 424 extending perpendicularly or normal to the top wall 354. An angled edge 425 is adjacent to and angled from the first portion 424. In typical embodiments, the angle between the first portion 424 and angled edge 425 will be between at least about 90°, typically about 120-170°, and preferably about 150°. Immediately adjacent to and intersecting the angled edge 425 is edge 426.
  • the edge 426 preferably is generally parallel to the top wall 354.
  • the edge 426 and the angled edge 425 intersect to form the nose 416.
  • the angle between edge 425 and edge 426 is at least about 15°, typically about 30-80°, and in preferred embodiments about 60°.
  • first and second sidewalls 372, 374 include sloped or beveled edges 418, 419, respectively.
  • the nose 416 extends or projects beyond the beveled edge 419.
  • the nose 416 also extends beyond the beveled edge 418, although not illustrated in FIG. 20.
  • the nose 416 acts to engage or bump into the second region of ultrasonic crushing 398. This engagement between the nose 416 and the second region of ultrasonic crushing 398 prevents someone from forcibly sliding the slider housing 352 off of the end of the package 410.
  • the slider housing 352 includes first and second standoffs 401, 402.
  • Standoffs 401, 402 are constructed and function analogously to standoffs 201, 202 described previously.
  • the first standoff 401 in the illustrated embodiment, includes a rod 403 extending or projecting from the first sidewall 372.
  • the second standoff 402 includes a rod 404 extending or projecting from the second sidewall 374.
  • the slider device 350 is operated in a similar manner as described above for slider device 352.
