Abstract: An easy-open beverage container and opening system therefor includes an opening provided in a barrier wall. Covering the opening is a tamper-evident pull tab having a holding portion and a topmost free end portion. An adhesive adheres the holding portion to an outside surface of the barrier wall so that the hole is sealed. A pair of slits is provided in the holding portion at opposite lateral edges of the holding portion adjacent the free end portion and the respective slits extend inwardly and downwardly away therefrom. The consumer grasps and pulls the non-adhered free end portion downwardly toward an opposite end of the holding portion to expose the opening. This causes a peeled part of the holding portion initially to be pulled from the barrier wall until the slits are reached; at which time the peeled part laterally separates from a remainder of the holding portion initially along the slits and then further along tear lines beginning at the lowermost ends of the slits to expose the opening.

Abstract: A reclosable plastic bag comprises first and second opposing panels fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. The bag is provided with a reclosable zipper extending along a mouth formed opposite the sealed bottom. The zipper includes a male track with a male profile and a female track with a female profile. A slider is slidably mounted to the zipper for movement between a closed position and an open position. The male and female profiles are engaged to each other while the slider is in the closed position. The male and female profiles are disengaged from each other in response to movement of the slider to the open position. To prevent tampering with the contents of the plastic bag prior to being initially opened, the slider is initially parked in the closed position at one end of the zipper, and upper edges of the male and female profiles are detachably connected to each other, except at the one end of the zipper supporting the parked slider.

Abstract: A package closure for such packages as reclosable plastic bags includes male and female interlocking profiles and a tear bead on one side of a zipper tape film. On the other side of the zipper tape film are two tear containing strips, preferably of ethylene vinyl acetate. In use, the zipper tape film is in a folded condition with male and female profiles interlocked. This places the tear containing strips on opposite sides of the outside of the folded zipper tape film, where they cooperate in serving to seal and bond packaging film to the zipper tape film, and to prevent the tear formed when the package is initially opened from running to the profiles.

Abstract: A method and an apparatus for applying a reclosable profile element and a tear strip element to a packaging film is disclosed. Packaging film is formed into a tubular form about a forming tube. The tubular shaped packaging film is advanced along the length of the forming tube and over a product fill tube having an outer perimeter less than the outer perimeter of the forming tube. The packaging film is deformed to conform to the outer perimeter of the product fill tube. Excess packaging film, made available due to the differences in outer perimeters of the forming tube and product fill tube, is formed into a loop. A reclosable profile element is guided into the loop and adhered to the inner surface of the loop. A tear strip is also provided which may be adhered to the packaging film prior to said film into a tubular shape about said forming tube, or may be guided into the loop of said film.

Abstract: A zipper closure strip for attachment to the top of a formed, filled and sealed package is provided. The zipper strip has a pair of interlocking profile members that extend from bowed webs which conform generally to the cross section of the top of the filled package. The strip may thus straddle the top of the package, gable fashion, and be bonded to the top of the package by heat seals, adhesive or the like. A slider seats on the profile members for urging them into engagement or forcing them apart. A blade protrudes through the slider from a plunger to enable the film at the top of the package beneath the closure strip to be slit. The zipper may be cuffed to expose the top end of the package to facilitate opening.

Abstract: An easy-open container includes guide strips to limit tearing to areas adjacent to the intended line of tearing with a tear strip.

Abstract: Stacks of folded paper tissues are usually enwrapped with a thin foil, thus forming a soft pack. Lately these packs are provided with a reclosable opening aid. This opening aid can be arranged in the region of a narrow longitudinal face of the pack, with an outer folding flap (18) at the same time serving as closing flap (23). In order to facilitate handling and to ensure a higher stability of the pack, the opening aid is designed such that only a portion of the outer folding flap (18) is formed as a closing flap (23), while the inner continuous folding flap (17) remains in the original pack position even when the pack is opened. The ends of the folding flap (17) are anchored to marginal side cross-strips (28, 29) of the outer folding flap (18). A recess (29) arranged preferably central in the region of the inner folding flap (17) and being open towards the free edge expediently enlarges the extraction opening (30) for the paper tissues.

Abstract: An easy-open container includes a membrane forming the top edge of the container and hermetically sealing the contents thereof. Elements for opening the container are disposed on the membrane, and includes a first bead of thermoplastic material and a first perforated line for tearing across the membrane. In one embodiment the membrane is disposed inward from the mouth of the bag, leaving portions of the bag walls extending upward beyond the container top edge to form guide rails which facilitate opening of the container. One guide rail is removed as the bag is opened and remaining portions of the bag walls are offset to enhance access to the bag contents. A membrane for sealing the mouth opening of a bag-like structure is also provided, as are methods for making an easy-open container and for making a membrane having the strcutures aforesaid.
