Abstract: The present invention is a thin, soft resilient pad or gasket having a durometer rating of less than or equal to 30, scale shore A, releasably mountable to a rough (or at least non-smooth) or smooth surface by reason of its resiliency and inherent surface tackiness, and may be made of hydrated cross-linked silicone polymer, or of aromatic or aliphatic base urethane or polyurethane, advantageously with bound migrating plasticizers to reduce oily surface residue on the gasket.

Abstract: A molded structure formed in a mold having a space, the molded structure itself constituting a molding body when combined with an upper mold. The molded structure has a substrate which may be a carrier frame for an electrical connector. An insert which may be an elastomer is disposed on the substrate and formed in the space in the mold. A deformable (preferably elastic) molding seal is disposed directly on the substrate and under the elastomer, the molding seal preventing elastomer flash during molding. The molding seal may be a ridge surrounding the space of the mold in which the elastomer is formed. The substrate may also have a datum surface on which the mold locates, with the molding seal disposed in a plane which differs from the plane of the datum surface of the substrate. A process of molding the insert on the substrate is also provided.

Abstract: A container mouth (21) is sealed with an inner seal which comprises a reseal liner (9) fitted inside of a cap (23) and a seal cover (10) separably laminated to the reseal liner and remaining on the container mouth after the container (20) is uncapped. The seal cover comprises a metal foil (5), a glassine paper (7) layered on the underside of the metal foil, and a hot-melt adhesive layer (8) coated on the underside of the glassine paper by gravure roll coating process. A polyethlene film (6) is preferably layered between the metal foil and the glassine paper to provide a better peel-off strength therebetween. The glassine paper may be replaced with an easy-peelable plastic film, such as a PET (polyethlene terephthalate resin) film. The inner seal fitted in the cap is placed onto the container mouth, and then the cap is subjected to a high frequency of 20-600 KHz to melt the hot-melt adhesive layer, whereby the seal cover hermetically seals the container mouth.

Abstract: The invention relates to a stopper for use in a substantially cylindrical bottle opening. The stopper has a substantially cylindrical shape to seal the bottle opening and includes a first polymer portion and a second material portion, wherein the second material portion coaxially overlies the first polymer portion. In another embodiment, the stopper includes a third polymer portion wherein the first polymer portion coaxially overlies the third polymer portion. The invention also relates to a method of protecting liquid in a bottle with a substantially cylindrical bottle opening. The method includes providing a stopper having a substantially cylindrical shape to seal the bottle opening and closing off the bottle by insertion of the stopper into the bottle opening. The invention also relates to a method of producing a stopper for use in a substantially cylindrical bottle opening.

Abstract: A self-adhesive reinforced foam gasket comprising a release liner having an upper surface which is a release surface, a layer of pressure sensitive adhesive applied to the release surface, a layer of flexible polymeric film, preferably polyester film, applied to the pressure sensitive adhesive layer, and a layer of flexible foam, preferably closed cell PVC flexible foam, thermally bonded to the flexible polymeric film layer. A length of material for die-cutting the gasket therefrom is provided, along with a method of making the length of material. The gasket may be used in automobiles and other applications.

Abstract: By achieving an extruded, foamed core formed from plastic material peripherally surrounded and integrally bonded with a cooperating synthetic, plastic, extruded, outer layer, a unique, multi-component, multi-layer synthetic closure is provided which may be employed as a bottle closure or stopper for any desired product, whether the product is a liquid, a viscous material, or a solid distributed in a bottle or container and dispensed through the open portal of the container neck. The present invention achieves a mass producible, resilient, synthetic bottle closure which is employable for any desired bottle, including wine. By employing the present invention, a multi-component or multi-layer synthetic closure is attained which possesses physical properties substantially equal to or better than the physical properties found in cork material, which has caused such cork material to be the principal closure material for wine bottles.

Abstract: The invention relates to polymer blends which can be used both in foamed and unfoamed states as a replacement for conventional EPDM and other elastomers. The composition of the blend includes a single-site catalyzed polyolefin resin having a density of below 0.878 g cm−3 and up to 40 weight percent a polyolefin including ethylene and propylene. The polymer blend is cross-linked. The polymer blends are formable and foamable. The use of sulfur to vulcanize the polymer blend is not necessary. The polymer blends can be used to make foam for floatation or for making gaskets.

Abstract: In order to provide a liner which can be used in place of existing type liners used in a closure for a container, a multiple layer liner sheet is coextruded in a manner wherein the outer layers are skin layers formed of a gas permeable material. These layers enclose a gas barrier layer and a foamed layer which respectively prevent the invasion of oxygen from the ambient atmosphere and remove oxygen from the head space to safeguard the contents of the container. The foamed layer provides the liner with the required resiliency, provides space for the inclusion of an adequate amount of oxygen scavenging material, and also provides a cellular structure which allows the gas molecules the freedom to move and quickly come into contact with the oxygen scavenging material.

Abstract: A self-adhesive reinforced foam gasket comprising a release liner having an upper surface which is a release surface, a layer of pressure sensitive adhesive applied to the release surface, a layer of flexible polymeric film, preferably polyester film, applied to the pressure sensitive adhesive layer, and a layer of flexible foam, preferably closed cell PVC flexible foam, thermally bonded to the flexible polymeric film layer. A length of material for die-cutting the gasket therefrom is provided. The gasket may be used in automobiles and other applications.

Abstract: A lid for foodstuff containers includes a shell shaped so that it can be fitted over an opening in a container, and a PVC-free seal, bearing an inscription, attached to the bottom of the shell and able to seal the lid to the container; the seal is applied to the bottom of the lid by applying adhesive paint between the bottom and the seal; this paint which can be used to control the adherence of the seal to the bottom, consists of a mixture of synthetic resins and hydrocarbons with added metallic pigment; a film bearing the inscription is applied over the paint, said inscription made using an ink which has a given chemical-physical affinity with the material used for the seal; it is, therefore, easy to detach the seal from the bottom of the lid upon which the inscription is clearly reproduced.
