Abstract: A reclosable pouch is provided having front and back walls and an opening along its upper edge. A first fastener profile is sealed on its ends to the exterior of the front wall of the pouch. The fastener profile extends longitudinally near the pouch opening. A second fastener profile is sealed on its ends to the exterior of the back wall of the pouch. The first and second fastener profiles each have a rib member extending longitudinally thereon and a groove for reception of the oppositely disposed rib. The fastener profiles are adapted for interlocking with the front and back walls of the pouch being interposed therebetween. A method and apparatus for manufacturing the aforesaid pouches are also described herein.

Abstract: A disposable bag mouth opener is equipped to a bag (1) in a stage of charge and packing or in a stage of purchase by a consumer, the bag being sealed after charge of contents. This opener has a simple design comprising a bag attachment plate (2) and a holding device (3) for hold. The bag attachment plate (2) is provided with a mouth end (20) and a plate section (22) having characteristic of contact and separation and forming a cause of contact and separation of inner surfaces of the mouth end (20). The holding device is provided with an inner wall narrow portion (30) having a design which can hold and support the mouth end (20). The attachment plate (2) is attached by suitable means to the bag (1) at a section of bag mouth level of a projecting edge surface (10) previously provided or additionally provided on the bag (1) in the form of a projection.

Abstract: Disclosed are bags especially adapted to be made from plastic material and in which the bag body film or material and extruded plastic zippers are fusibly incompatible. A pair of extruded plastic zipper strips having reclosable zipper profiles facing toward one another along the lower sides of pull flanges of the bag have the opposite ends of the strips sandwiching opposite side seal seams of the bag therebetween. The opposite side seal seams have holes therethrough, and fused connecting anchors formed from the material of the zipper strip ends extend through the holes. The bag may be closed by squeezing the zipper strips together so that the profiles interlock with one another and interlock the intervening area of the bag walls therebetween. A method of making the bags is also disclosed.

Abstract: A closure device for a surgical post-operative drainage bag comprises a first panel which is curved and a second panel. The two panels are joined by a hinged connection. The second panel comprises two strip-like portions joined together by an intermediate hinge. When the device is closed, the free edge of the second panel tightly engages within the inside of the lip so as to be placed in a stressed condition and so that a portion of the bag positioned between the inside of the lip and the free edge of the second panel may be secured.

Abstract: An elongated, plastic resealing clip is provided for a bag containing a flowable product and comprising a plurality of panels hingedly coupled along fold lines, an opening at one end of the bag, and a flap hingedly coupled to one panel along a fold line for overlapping an opposite panel and closing the opening. The clip is U-shaped in transverse cross section with a bight for engaging the flap fold line and depending legs for pressing the flap against the opposite panel. An adhesive layer extends across the entire width of the flap to seal the flap to the opposite panel. The adhesive layer seal can have a reduced bonding strength adjacent one end of the flap to facilitate opening of the flap at the reduced bond strength section. The reduced bonding strength is provided by an adhesive coating comprising kaolin clay. This arrangement is particularly useful in heavy weight bags which are sealed by a hot melt adhesive.

Abstract: A closure device adapted for clamping a flexible bag has a pair of hinged jaws including slideably mounted extension pieces adjustably retained in pre-selected positions of extension. The jaws are movable between a closed position to grip a bag and an open position to release the bag. A clasp mechanism releasably retains the jaws in the closed position. Mating sets of longitudinal teeth may be provided to grip the bag more positively.
