Abstract: A simple and versatile pocket wrap for a comestible product which is frequently hand held during consumption. The wrap is constructed to provide a pocket adapted to enclose the comestible product, with the pocket being formed by front and back sheets which are joined along both a first side edge and a bottom edge, and which are openable and detached along both a second side edge and a top edge. The relatively open pocket enables a comestible product to be easily inserted therein, and also allows the comestible product to be conveniently relocated in the pocket to extend therefrom during consumption while still remaining wrapped therein. An overwrap sheet is formed integrally with the pocket back sheet, and extends upwardly therefrom, with the overwrap sheet being designed to be folded downwardly over the pocket front sheet after insertion of a comestible product into the pocket, thereby wrapping and packaging the comestible product in a manner suitable for initial delivery to a customer.
Abstract: A disposable plastic bag is provided having a closure formed by a plurality of ripple strips where each ripple strip comprises a band of rows of adjoining waves, the waves being shaped and positioned such that the highest amplitude of one row is adjacent to the lowest amplitude of the nearest rows. In one embodiment, the highest and lowest points of each row have flanges extending therefrom which interlock with the waves of a facing strip. In a second embodiment, the width of each row is regularly varied and the widest portions of each strip interlock with the widest portions of a similar facing strip.
Abstract: This invention relates to compact, easily transportable, moist tissue or towelette dispensers which are so designed that they maintain the tissues contained within the dispenser in moist condition for exceptionally long periods of time, thus providing long shelf life for merchants, who stock the dispensers, as well as a long life span of the dispensers for the consumer.
Abstract: Adjoining strata of pressure-sensitive adhesive are transferred to a package substrate. The two outermost adhesive strata have different adhesion to the substrate. The adhesive strata are used as a reclosable fastener and are intermixed in the course of reclosing and reopening the package, the action being such as to advantageously compensate for contamination occurring at the reseal interface while maintaining the status quo at the permanent interface.
Abstract: A closure suitable for use with a flexible bag, such as a sandwich bag where the closure comprises at least one female strip affixed to a first surface, the channel having a layer of pressure sensitive adhesive less than the depth or the interior height of the channel and located on an internal portion of the channel, and a second surface, whereby the seal is formed by contacting the pressure sensitive adhesive layer in the channel with a portion of the second surface.
Abstract: Articles are provided that include pressure sensitive adhesive compositions which are especially suitable for forming contact bonds that are resealable at room temperature. Such adhesive compositions include a blend of a linear or a radial block copolymer, an end-block modifying resin compatible with the end or thermoplastic block of the copolymer and incompatible with the mid or elastomeric block, a plasticizing process oil compatible with the mid or elastomeric block; and, only if desired, not more than about 14 weight percent of a mid block or elastomeric block associating or modifying resin compatible with the mid or elastomeric block and incompatible with the end or thermoplastic block. Articles that particularly advantageously utilize these compositions are thin-walled storage or sandwich bag products made of a polyolefin or other film that has a releasable and resealable sealing strip. Others include peelable labels and note pads and dispensers for thin storage wrap products.
Abstract: A bag for containing a flowable product comprises 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. An adhesive layer extends across the entire width of the flap to seal the flap to the opposite panel. The adhesive layer seal has a reduced bonding strength adjacent one end of the flap to facilitate opening of the flap at the reduced bond strength section. The flap after being sealed to the opposite panel, is reversely bent 180.degree. along with the sealed opposite panel about a lower fold line and portions of the fold extending inwardly from opposed distal ends of the bag are either adhesively tacked or stapled to the one panel to form a finger grip handle therebetween for carrying the bag and its contents.
Abstract: A resealable bag for containing a flowable product comprises a plurality of panels hingedly coupled along fold lines, an opening at one end of the bag, a flap hingedly coupled to one panel along a fold line for overlapping an opposite panel and closing the opening, and a strip of adhesive tape for opening and resealing the flap. 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 abhesive coating comprising kaolin clay. This arrangement is particularly useful in heavy weight bags which are sealed by a hot melt adhesive.
Abstract: A bag device A is disclosed having a waterproof enclosure D contained within an outer case B having a cover flap C which fastens over a closure 18 by means of a yieldable fastener 20, 22 to seal an article within enclosure D in a generally airtight waterproof environment. Air entrapped therein provides buoyancy and a safety fastener E maintains the closure 18 sealed should cover flap C become unfastened under pressure such as when fallen upon during whitewater boating.
Abstract: A multi-purpose holding device including a receptacle or pouch and a fastener particularly advantageous for use in moving vehicles. The surface of the pouch and one side of the fastener are constructed of complementary a hook and loop material which allows the pouch to be attached to and removed from the fastener. The other side of the fastener contains an adhesive for securing the fastener to an object base. The device is useful for holding many different objects. The holding device is also adapted to hold and insulate an open beverage container without spilling its contents. The pouch also preferably contains a second compartment and a slot between the surface of the pouch and a strip of light-reflecting material. As a result of the strip of light-reflecting material and the construction of the pouch and fastener the holding device is also adapted for use as a warning device.
Abstract: An improved adhesive system for forming resealable channel closures for flexible bags such as thermoplastic bags made from polyethylene, e.g. sandwich bags. The adhesive system comprises a layer of hot melt adhesive over which a thin second layer of a liquid-based adhesive such as a water-based pressure sensitive acrylate is applied.

Abstract: An improved Z-fold closure for flexible bags such as thermoplastic bags comprising polyethylene film comprising a pressure sensitive adhesive strip and a protective strip having one or more ribs of sufficient stiffness and dimension so that the strip of adhesive is substantially contacted by only the top portion(s) of the rib(s) when the bag closure is in a stored or "z" fold position.
