Abstract: Apparatus 10 has breachable flow conduit 12 for discharging stored fluid 12F contained in storage chamber 10C out to the ambient. Chamber access region 10R is positioned proximate perimeter 10P of the apparatus. The breachable flow conduit is within the access region, and has an inner end 12C proximate the storage chamber and an outer end 12P proximate the perimeter of the apparatus. The flow conduit has outer pressed seal 14P between the outer end of the flow conduit and the perimeter of the apparatus. The flow conduit also has inner pressed seal 14C between the inner end of the flow conduit and the edge of the storage chamber. The flow conduit expands towards the perimeter of the apparatus under external pressure, typically applied by the consumer. The pressure causes the flow conduit to breach at the perimeter of the apparatus. The flow conduit also expands towards the storage chamber. The pressure causes the flow conduit to breach at the edge of the storage chamber.

Abstract: The present invention relates to an airbag cushion which exhibits a low amount of seam usage (in order to attach at least two fabric panels or portions of a panel together) in correlation to an overall high amount of available inflation airspace within the cushion itself. These correlated elements are now combined for the first time in what is defined as an effective seam usage index (being the quotient of the length of overall seams on the cushions and the available inflation airspace volume). The inventive cushion must have at least one substantially straight seam and must possess an effective seam usage factor of less than about 0.11. A cushion exhibiting such a low seam usage factor and also comprising an integrated looped pocket for the disposition of an inflator can is also provided as well as an overall vehicle restraint system comprising the inventive airbag cushion.

Abstract: A tamper indicating, resealable closure for a package includes first and second film layers releasably adhesively joined together such that the first and second film layers are at least partially separable when the second film layer is pulled away from the first film layer. The first film layer includes first and second tear lines formed thereon to define first and second panel sections respectively. The first panel section defines an access opening through the first film layer when it is separated along the first tear line during an initial separation of the first and second film layers. The second panel section also becomes separated from the first film layer when the second film layer is separated from the first film layer to provide an indication of an initial opening of the closure. Subsequently, the second film layer may be re-adhered to the first film layer to reseal the access opening, while the second panel section remains separated from the first film layer.

Abstract: A tamper-evident reclosable package having a header that is tack sealed to the zipper. A light tack, in the form of a light weld, is made at the end of the package header. The header is the top portion of the package and is designed to shroud the zipper. The header serves as a tamper-evident feature, and also serves to maintain cleanliness and aesthetics of the package. The header must be tom before a person can gain access to the contents of the package. Typically, means for preferential tearing are provided for easy removal of the header. The tack seal contributes to the maintenance of the cleanliness and aesthetics of the package, while still allowing easy removal of the header. The tack is light (i.e., low bond strength or pull-off force) in order to not make it significantly more difficult to open the package.

Abstract: Merchandise container (10) has location specific breaching at breaching focus (12F) when shaped breaching bubble (12S) is in compression. Base lamina (10B) and opposed cover lamina (10C) are selectively pressed together into a double convex receptacle (see FIG. 1B). Product chamber (12P) and the breaching bubble are included within a perimeter seal (14P). Inner seal (14I) extends across the container, isolating the product chamber from the breaching bubble. Bubble incursion zone (12Z) shifts the perimeter seal inward toward the breaching bubble. Breaching focus (12F) initiates the breach at the inward most point or location of the incursion zone. Breaching flanks (14K) adjacent to the breaching focus form the breaching edge. The breaching bubble is compressed under external pressure applied by the end user, indicated by arrows (12C) and (12B) in FIG. 1B, causing the opposed laminae to separate. Opposed peel flaps, cover peel flap (14C) and base peel flap (14B) (see FIG.

Abstract: Breaching access structure 10S provides easy access to sealed interior 10I containing contents 10C. Access region 12A proximate edge 12E of package 10, provides entrance into the interior and access to the contents. Band seal 14 formed by upper lamina 14U and lower lamina 14L extends along the access region, enclosing breaching bubble 16. The band seal has inner seal portion 14I between the bubble and the interior, and outer seal portion 14O between the bubble and edge 12E of the package. The bubble is expandable to open the package in response to bursting detonator 18. The detonator is burst by external pressure applied by a user. Opposed pair of peel flaps, upper flap 16U and lower flap 16L, are formed by the opposed laminae of the outer seal along the edge breach as the bubble breaches. These small initial flaps are grasped by the user and manually peeled apart to initiate opening the band seal.

Abstract: Breachable product container 10 is formed by first lamina 10B and opposed second lamina 10C selectively pressed together. Perimeter seal 10S extends around the perimeter of the container. Product chamber 12P and inflatable breaching bubble 12 are between the selectively pressed opposed laminae, within the perimeter seal. Product 16 is contained within the product chamber. Inner divider 14D extends between the product chamber and the breaching bubble. Transfer passage 14 through the inner divider permits inflation of the breaching bubble in response to moderate pressure applied to the product chamber during an extended inflation period. Breaching edge 12E forms part of the perimeter seal around the breaching bubble. The breaching edge provides an edge breach by separating the opposed laminae along the breaching edge in response to substantial pressure applied to the breaching bubble during a brief breaching period.
