An improved two-piece container seal suitable for sealing a container having a removable closure and for lining the closure comprises a flexible sealant sheet and a flexible liner sheet bonded thereto. The sealant sheet and liner sheet are of the same size and shape. The sealant sheet has a sealing surface and a first thermoplastic surface, and the liner sheet has an outer surface and a second thermoplastic surface. The first and second thermoplastic surfaces are in opposed, congruent contact with each other, and the first thermoplastic surface is ultrasonically welded to the second thermoplastic surface by an array of spaced, frangible ultrasonic welds, forming an adhesive-free interface therebetween. A method of manufacturing a two-piece container seal and a sealed container comprising a two-piece container seal are also described.

An container sealing material suitable for sealing a container comprises a liner sheet (liner), a sealant sheet, and an interlayer portion (interlayer) bound between the liner and the sealant sheet by individual layers of wax. The material has a closure-contacting surface and a heat-sealable surface. At least one of the surfaces of the liner and the interlayer that contacts a layer of wax is capable of absorbing liquid wax when the layer of wax is melted. At least one of the surfaces of the sealant sheet and interlayer which contacts a layer of wax is capable of absorbing liquid wax when the layer of wax is melted. The liner and the sealant sheet each release from the interlayer when sufficient heat is applied to the container sealing material to melt the layers of wax. The interlayer can include printed matter visible on one or both of its surfaces (e.g., a logo, proof-of-purchase indicator, and the like). The printed matter can include promotional indica for a product, a service, a game and the like. Accordingly, the container sealing material provides a means for including a promotional token, such as a redeemable coupon within a container closure between the liner and the sealant sheet.

The impregnation of a composite tape (56) having a porous matrix with HTC particles provides for permeating a fabric substrate layer (51) of the composite tape with HTC particles and impregnating an impregnating resin into the composite tape (51). The HTC particles in the fabric (51) layer are comprised of a meso-micro mixture, which is between 1:4 to 4:1 meso sized particles to micro sized particles. Other smaller particles may also be included at lesser concentrations. The impregnating resin itself may also contain HTC particles.

The invention relates to a felt material comprising at least one felt layer and an absorbing layer, to a method for producing the felt material, and to the use of the felt material in textiles, shoes, technical application or medical applications. The felt material according to the invention has the advantages of conventional felt materials regarding the warming and damping properties and is permeable to air in the dry state. Due to the special design, however, it is waterproof in the wet state and thus it is suitable for sealing many materials. The felt material according to the invention binds more humidity or binds water in a different way than common felt materials.

Curable material comprising silylated polymers containing urethane groups, and use thereof in sealants, adhesives, binders and / or surface modifiers.

An integral multilayer joint seal. Layers of foam, layered co-planar to the adjacent surface, are interspersed with a barrier layer which extends beyond the foam layers to provide a protective surface, a surface for attachment atop adjacent substrates, or a connecting tab for use with adjacent joint seals. The foam layers may be uncompressed or partially compressed at the time of joint formation and may be composed of open or closed, or hybrid, cell foam. The foam may be impregnated with a fire retardant or may be composed of a fire retardant material, if desired. The barrier may have a tensile strength greater than the adjacent foam. The joint seal may have an elastomer, such as silicone, at its top and / or bottom, and may even include an elastomer layer within or about the barrier.

A low stress to seal, unitary gasket tape is provided that is particularly suited for use in form-in-place gaskets. The gasket tape preferably comprises at least two joined porous expanded polytetrafluoroethylene (ePTFE) tapes aligned along tape side surfaces and a substantially air impermeable layer there between. The plane of expansion of the ePTFE is substantially parallel to the flange surface providing longitudinal and transverse strength. The substantially air impermeable layer prevents fluid from permeating through the gasket in the radial direction.
