Abstract: This invention relates to a hinge type pressure sensitive resealable closure system for a container. The invention comprises an essentially flat strip of suitable material that is permanently adhered at one surface to the container, such adherence normally by a permanent pressure sensitive adhesive, but it could be heat sealed or otherwise attached to the container in a permanent manner. Another surface of the strip is adapted by virtue of a removable pressure sensitive adhesive to be repeatedly removably attached to the container with the respective permanent and removable attachments closing the container in a repeatable resealable mode. The strip can include printing thereon, and other suitable surfaces could include more removable pressure sensitive adhesive for various more sophisticated closure techniques.

Abstract: A seal for a bottle and cap assembly. The seal is formed from a heat shrink sheet which is adhesively coated on one side. A pull tab is formed by a pair of cuts in one edge of the sheet forming the seal and a tear strip is adhesively secured to the back of the sheet in registration with the pull tab. After being adhesively secured to a bottle and cap assembly, the sheet is heat shrunk to conform to the contour of the bottle and to provide a flange over the bottle cap. In one embodiment the pull tab is in registration with the area of joinder between the cap and the bottle and in another, the sheet is devoid of adhesive in an area extending from the pull tab and bridging the joinder between the cap and bottle. In either case, pulling of the pull tab separates the sheet into a first piece adhered to the cap and a second piece adhered to the bottle allowing for the only possible access to the bottle without evidence of tampering showing in the sheet.

Abstract: A protective, easily removable laminate for application to the carpeting, and decorative seat and wall covering material of vehicles includes a plastic film coated on one surface with an acrylic resin based pressure sensitive adhesive. The film, in one form of the invention, is comprised of unoriented polypropylene capable of stretching and withstanding deep drawing and resisting the heat involved in thermoforming. The pressure sensitive adhesive is essentially of the type which does not adversely affect paint or trim material and which has preferential adhesion failure to the carpeting or seat or wall covering rather than to the film. In another form of the invention, the film, where it is not to be subjected to thermoforming operations, may be of a different composition such as polyethylene terephthalate, oriented polypropylene, polyethylene, or polyvinyl chloride. The method of employing the film in all forms of the invention is to apply the pressure sensitive adhesive to one surface of the film.

Abstract: A composite pressure sensitive adhesive construction has an adhesive portion located laterally on each side of a carrier. The central portion of the carrier is free from adhesive. A split release liner covers each adhesive portion. In use, the adhesive construction can be applied to any article, for example an insulation tube, and especially articles having a split or opening so that the article can be secured in a closed position. Moreover, the adhesive construction can have one laterally adhesive portion applied to the article, with the remaining adhesive portion having the release liner thereon which is readily removed and the remaining adhesive portion securely engaged to the article.

Abstract: A moisture and oxygen barrier laminate which can be applied to a surface of photographic or printed material. The laminate also has an adhesive layer containing ultraviolet light absorbers therein. In the one embodiment, the laminate is transparent, thus allowing continuous display of a photographic or printed material. In another embodiment, the multilayer device is opaque, thus completely blocking the transmission of both ultraviolet and visible light to the photographic film or print. In the latter embodiment, the multi-layer device is removed for display of the photographic print or film and subsequently reattached during storage.

Abstract: A transmissive reflector which both reflects light and lets light pass therethrough. The transmissive reflector comprises a nacreous pigment in combination with a transparent adhesive. The nacreous pigment and the transparent adhesive can be separately coated on a clear or transparent substrate or combined as a blend or mixture thereon. The transmissive reflector imparts lustre or a pearlescent effect to light as well as diffuses the light and, thus, enhances the appearance of various articles such as transparencies, rear projection screens, projection television, and the like. Also, when utilized as a reflector as for a background, the reflected light has a lustre imparted thereto and thus any article displayed is distinctly set forth, as for example, a liquid crystal readout, and the like.

Abstract: A composite pressure sensitive adhesive construction contains a central release liner, a layer of an adhesive on each side thereof, and optionally, an exterior release liner on at least one of the adhesive layers. The central release liner and the exterior release liner contain release coatings on surfaces thereof which contact the adhesive layer. The pressure sensitive adhesive construction may be utilized in sealing pipe insulating jackets wherein the exterior release liners are removed and the adhesive construction is applied to the opposite longitudinal ends or sides of the insulating jacket cover. The insulating jacket may then be stored until utilized whereupon the central release liner is removed, the jacket inserted about the pipe, and a sealing connection then made by pressing the two exposed adhesive layers together.

Abstract: A phosphorescent safety tread made from a laminate including a backing layer, a layer of pressure sensitive adhesive on the backing layer, and a carrier film and which includes, on the surface of the carrier film, a layer of light-colored grit bonded to a face surface of the carrier film and a size coat applied over the grit and aiding in bonding the grit to the carrier film, which size coat includes phosphorescent pigment particles embedded therein for light storage and reflective action and use of the laminate as a phosphorescent safety tread or other similar purpose.

Abstract: A pressure sensitive adhesive composition comprising the solids deposited from a mixture of solvents, synthetic rubber and tackifiers and also including a polysiloxane additive in about 6 to 10 percent of the resultant composition, which composition has reduced edge ooze or flow when on sheets subjected to a cutting action.

Abstract: A composite pressure sensitive adhesive construction contains a central release liner, a layer of an adhesive on each side thereof, and an exterior release liner on at least one of the adhesive layers. The central release liner and the exterior release liner contain release coatings on surfaces thereof which contact the adhesive layer. The composite construction may be made up in the form of a roll for easy dispensing or in the form of a precut tape. The pressure sensitive adhesive construction is generally useful for making any type of sealing connection wherein an initial releasable connection is desired. For example, the pressure sensitive adhesive construction may be utilized in sealing pipe insulating jackets wherein the exterior release liners are removed and the adhesive construction is applied to the opposite longitudinal ends or sides of the insulating jacket cover.

Abstract: The laminate includes a partially cured flexible acrylic face sheet having a primer layer on one surface thereof bonded to a binder layer having a layer of reflective glass beads embedded therein and protruding therefrom. The laminate being completed with the spacer layer bonded to a bead embedded binder layer. A reflective mirror-like thin metal coating is provided on the outer surface thereof. The improvement resides in using a supported spacer layer so that no stretching of the spacer layer occurs during lamination, thus resulting in lessening of visual defects such as wrinkles and the like and crossbanding in the reflectant characteristics. The process further eliminates the use of a seal coat as well as combining bead coating and lamination into one step rather than two as in the prior art.

Abstract: An in-line method of forming a laminate of a heat sensitive foam sheet material, and a hot extruded polymeric product comprising hot extruding a polymeric material into a shaped product and while still hot contacting the shaped product with a face of the heat sensitive foam sheet material and thereafter cooling the resulting product. Such face is previously coated with a layer of a heat sealing substance which is activated at a temperature below the softening point of the heat sensitive foam sheet. The heat seal contact takes place under minimal pressure when the surface temperature of the shaped product is still high enough to activate the heat sealing substance but not high enough to damage the heat sensitive sheet. The laminates so made are part of the invention.
