Abstract:
A package having two or more compartments, adjacent compartments being seperated by a peel seal tape. A peel seal is formed by joining peel seal material coated on one surface of a substrate to one package wall, the other surface being coated with sealant material for hard sealing the substrate to the package wall. The substrate and coatings are formed by extrusion. The adjacent compartments of the package are filled with different materials. When one compartment is squeezed with sufficient pressure, that pressure breaks open the peel seal, allowing the respective contents of the two compartments to be mixed without removing the contents from the still externally sealed package.
Abstract:
A well drilling bit or equivalent tool is provided with a protective carrying case in the form of an open bottom conically shaped plastic hollow bucket with embedded flexible cords or cables extending out of the upper wide mouth to receive plastic sleeve handles for manually carrying the awkward weight of the drilling bit in a protective case thereby preventing damage to the tool. The drill bit is held in place by two opposed endless flexible cord or cable arrays which are fastened together over the drill bit to hold it in mating registration with cutting edges against the conical interior plastic surface of the carrying case. The bit edges thus engage the soft plastic walls for a protective fit, and the awkward weight of the drill bit can be easily manually carried without fear of damage by dropping. Also the plastic protective cover shields the drill bit from damage from any object striking the bit.
Abstract:
A bundle of fasteners, such as screws, are held in parallel relation between two strips. One of the strips is substantially planar and the second strip is connected against the planar strip so as to partially encase the individual fasteners therebetween. The second strip is formed of an elastic material capable of stretching to the configuration of the individual fasteners. The package retains the accuracy of positioning of the individual fasteners. A layer of plastic material makes the bundle moisture resistant and avoids leaving any residue from the strips on the work.
Abstract:
1. A multi-layer web of packaging material for forming the walls of a packaging container, comprising: a substrate layer; a covering layer of thermoplastic material place on and in juxtaposition with said substrate layer; the covering layer having at least two zones extending substantially parallel to each other and substantially continuous in the direction of the length of the web; one of said zones being permanently secured to said substrate; the other of said two zones constituting a heat seal responsive seam zone releasable secured to said substrate; and a separating agent between said seam zone and said substrate.
Abstract:
An improved metal foil composite sheet and method of fabricating the same for heating and/or cooling food products. Metal foil is coated on one surface with a heat stable, thermoplastic, epoxy and on its second surface with a heat resistant, dielectric, thermosetting base coat and a top coat of a heat resistant, heat absorptive, thermosetting material. The top coat may be applied in zones of distinct thicknesses simultaneously. Such application provides for legible printing, while preserving the desired heat absorptive properties on the entire foil pouch stock including both the printed and unprinted regions. A completed foil pouch composed of the foil composite sheet permits uniform heating and/or cooling of foods over an extended range of temperatures and times while resisting undesired deterioration.
Abstract:
This invention comprises a corrugated package material wherein the corrugated fluting is attached to one or more sheets of heat shrinkable polymeric film. The heat shrinkable film is preferably on only one side of the corrugated fluting, but may be on both sides of the corrugated fluting. This packaging material is then formed into a carton and this carton filled; or is used to bundle a series of containers, and the final assembly, whether a carton or bundle, heat shrunk, whereby the strength of the corrugate is increased.
Abstract:
This disclosure is directed to an article of manufacture comprising of preformed synthetic water insoluble resins which may be either soluble or insoluble in an organic solvent that is subsequently impregnated with a volatile substance by contact with an aqueous emulsion of an essential oil and a surfactant wherein the impregnated resin article with gradually yield the volatile substance in a chemically unchanged, dry state to the surrounding atmosphere over a considerable period of time. The impregnated volatile substance may be either a fragrance, a flavor, or a combination of both, a sanitizing agent, or a medicinal agent.
