Abstract: There is provided a container having both male and female sealing regions disposed about its periphery in a pattern making it possible to seal a container with another container having substantially identical sealing regions. The male sealing regions used in the practice of the present invention may take the form of a U-shaped ridge which is undercut along at least one leg of the U in a radial direction. Typically, a container will be thermoformed from lightweight thermoplastic material giving the U-shaped ridge considerable flexibility. The female sealing regions used in the practice of the invention may take the form of an undercut channel adapted to receive and match the undercut U-shaped ridges found in the male portion of the container wherein the walls and base of the channel are sufficiently flexible that the undercut portions of the U-shaped ridge are urged into engagement with the undercut portions of the channel.

Abstract: A reclosable cup lid thermoformed from a polymeric material includes a domed member and an elongate closure panel. The thermoformed domed member is provided with a sidewall and a top wall, the top wall having upper and lower surfaces and a drinking aperture at a periphery of the top wall. The top wall further defines a pair of slide tracks depending from the lower surface of the top wall and also defines a post aperture disposed inwardly with respect to the drinking aperture. The elongate closure panel has opposed engagement edges, an upper surface provided with a post projecting upwardly therefrom, and a drinking aperture sealing area. As assembled, the domed member and elongate closure panel are configured such that the opposed engagement edges of the elongate closure panel are slidingly mounted in the slide tracks for generally radial displacement.
Abstract: A dispenser for inter-folded sheet includes a replaceable cartridge. In preferred embodiments, the replaceable cartridge includes a generally planar rectangular core having a stack of inter-folded food service sheets wrapped around the core in a U-shape and retained in position by shrink wrap.

Abstract: An improved paperboard has been bulk enhanced by retaining a substantial portion microspheres in a suitable distribution within the paperboard. As in one embodiment, the high retention of the bulk enhancing additives is believed to result from the incorporation of suitable retention aids. The paperboard is able to be formed into suitable paperboard containers without loss of integrity. The resulting containers have increased hold times when they contain hot or cold food or drink.

Abstract: A paper product with absorbency and moisture strike through resistance is disclosed. More particularly, a multi-ply paper product with improved strike through resistance is disclosed, wherein at least one ply is a wetting resistant ply comprising at least one wetting resistant compound and at least one ply is an absorbent ply possessing greater absorbency than the wetting resistant ply. In addition, a two-ply paper napkin with improved moisture strike through resistance is disclosed, wherein the wetting resistant ply comprises alkyl ketene dimer and the two plies are separately microembossed, glue laminated together in a point to point configuration, and macroembossed with coin edging. Furthermore, a multi-ply paper product with improved strike through resistance is disclosed, wherein a first ply comprises at least one wetting resistant compound and a second ply possesses greater absorbency than the first ply.

Abstract: A process for making absorbent sheet material from recycle furnish includes treatment with a synergistic debonder composition. The debonder is capable of reducing tensile strength by 40 percent or more by way of a quaternary ammonium surfactant component and a nonionic surfactant component.
Abstract: An auto-start dispensing container for sheet products includes a sealing member secured to a first sheet to be dispensed from the container. In a preferred embodiment, there is provided an auto-start dispenser for dispensing moistened inter-folded wipes which includes: (a) a container provided with a dispensing aperture for receiving a plurality of moist wipes; (b) a removable sealing member affixed to said container to seal the aperture wherein the sealing member and the container form an enclosure adapted to retain moisture; and (c) a lead sheet engaged with the plurality of moist wipes and secured to said removable sealing member, the removable sealing member and the lead sheet being adapted to draw a moist wipe partially through the aperture upon removal of the sealing member from the container. Preferably, the lead sheet is affixed to the removable sealing member by way of a hot-melt adhesive.

Abstract: A drink-thru lid for a drinking cup including an annular mounting portion for sealingly engaging the drinking cup, wherein the annular mounting portion includes a downwardly extending annular skirt. The lid further includes a tear-back section extending from the annular skirt to a hinge portion located in a medial portion of the lid. The tear-back section includes a raised protrusion extending outwardly from an upper surface of the lid. A recess is further formed in a medial portion of the lid on the opposite side of the hinge portion from the raised protrusion, wherein the tear-back section may be torn away from the lid on its sides and pivoted about the hinge portion until the raised protrusion is received within the recess for holding said pivotal flap open. The raised protrusion and the recess are shaped such that the raised protrusion is frictionally engaged by the end walls of the recess.
Abstract: Easy starting rolls of perforated tissue product which have a reduced tendency to ply separate are formed with an adhesively secured doubled over tail tab folded against the roll. The strength and location of the bonds are controlled by controlling the penetration of the adhesive into the tissue. The dry tensile strength of the projecting folded over tail tab exceeds 400 g/in and the caliper thereof exceeds one mil The adhesive bonds are spaced away from lines of perforation joining sheets in the initial sheets of the roll.

Abstract: An adjustable portion cup includes a bottom and a sidewall defining a scooped perimeter about the upper aperture of the cup. The sidewall is provided with an invertible sidewall panel which defines, in part, the contained volume of the cup in a first position and is operative to reinforce the opposite portion of the sidewall in a second position. The invertible panel is configured so that when displaced from a first position to a second position, it is detached from a lower portion of the sidewall to which it is joined and is in contact with an opposing portion of the cup sidewall, whereby the contained volume of the cup is reduced and the opposing portion of the cup sidewall is reinforced.
