Abstract: A receptacle liner for gripping the receptacle and method of making. A liner may be formed by one or more panels including at least one resilient segment extending from a bottom to a top of the liner. The liner segment can be coextruded so that the resilient segment is made from resilient material and other portions of the liner are made from another material that is less resilient. When the liner is placed in a receptacle, the liner can be expanded by resiliently stretching the resilient segment so that the liner may apply a gripping force to the receptacle. The liner can include gusseted side panels. A mouth can be formed as a recess in the top ends of front and rear panels and extend through the gusseted side panels to define handle portions and form apertures in the handle portions that open to the mouth.

Abstract: An adaptor, system, and method for collecting for a breast pump. A breast milk bag has a hole adjacent an end margin. The bag can have a reclosable seal and a zone of weakness for separating a sealed portion from a header. An adaptor has inlet end and an outlet end and defines a flow passage. The inlet end is securable to the outlet of the breast pump so liquid therefrom can flow through the flow passage. A slot extends through the adaptor wall to at least partially define a retainer for extending through the hole to mount the bag on the adapter. In a method of use, the bag is secured to the adaptor using the retainer, filled with breast milk, sealed while secured to the adaptor, and the sealed portion of the bag can be removed by tearing the bag along the zone of weakness.

Abstract: A plastic bag has a closure comprising first and second mutually interlocking profiles and a slider on the closure adapted to engage the interlocking profiles in locking relationship when the slider is moved across the profiles in a locking direction and to disengage the interlocking profiles when the slider is moved across the profiles in an opening direction opposite the locking direction. Topographical features are spaced periodically along the width of the closure. The topographical features are arranged for engagement with the slider as the slider moves across the profiles. Engagement between the topographical features and the slider produces a locking tactile and audible sensation upon closing the closure which is different from an opening tactile and audible sensation upon opening the closure.

Abstract: A plastic bag having a zipper-type closure which includes opposing closure members which each has a plurality of projections. The projections of the closure members are configured for interlocking and sealing engagement when the zipper is closed. At least one of the projections on one of the closure members is in one embodiment made of a softer material than at least one of the other projections. In some embodiments, the soft projection(s) are not configured for close tolerance fit with complementary mating projections. In some embodiments, the closure is used in combination with a slider. The closure can include deformations for providing tactile or audible feedback against movement of the slider. The closure can include slider rails at a top edge margin to minimize the size of the slider.

Abstract: A temporary adhesive band provides a releasable sealing structure and a tearing structure in a plastic bag. The band can be coextruded with one or more panels of the bag and can be made from a polymer blend. It can have a relatively thick tear section that defines a tear line at a zone of weakness in the bag so that a closed end of the bag can be easily removed. The band also can have a releasable sealing section that remains attached to the bag after the closed end of the bag has been removed by tearing the bag along the tear line so that the bag can be resealed once it has been opened. The releasable sealing section of the temporary adhesive band is preferably made from a coextruded material with tacky properties so that no additional adhesive is required for resealing the bag.

Abstract: A system and method for extruding film with a thickened profile section. In some embodiments, the film forms bags with integral zipper profiles. Plastic film is extruded to form a tube. During extrusion, cooling jets direct cooling gases toward the thickened profile section below the frost line to preferentially cool the thickened profile sections. In some embodiments, warm air is drawn out of the tube interior through hot air intakes located below the frost line. In certain embodiments, the film is extruded at a higher rate of speed than conventional processes. Likewise, the extruded film tube is expanded at a lower blow up ratio than conventional processes in certain preferred embodiments. In some embodiments, the extrusion system includes an air flow surface oriented relative to the film tube to define an air flow gap of substantially uniform thickness.
