Abstract: An improved instrumentation and method for manufacturing from film wrapping material hermetically sealed packages containing an untangled, unknotted segment of flaccid filament, and packages produced by the instrumentation and method. Instrumentation improvements include a gripper assembly for impeding uncut filament from backing up during filament loading in the course of package construction, an improved piston also impeding filament backup and facilitating deposition of a filament segment into an open package compartment, and a sealing mechanism for superimposing a seal over the top and bottom package seals.

Abstract: A first embodiment of a package including superimposed flexible opaque and transparent sides and a circumferential peripheral seal determining an interior sealed enclosure for storing a liquid material includes two contiguous depending seals separated by a preformed slot dividing the enclosure bilaterally into a storage reservoir and a dispensing channel in fluid communication. The dispensing channel includes a closed lower end contiguous to a notch in the peripheral seal. Tearing the package at the notch results in collaterally tearing open the channel lower end and a contiguous portion of the peripheral seal, thereby enabling removal of package contents. Use of a ruled scale imprinted on the opaque side proximate to the dispensing channel and viewing through the transparent side the disposition of material in the channel enable the selection of a measured quantity of material to be expelled from the channel.

Abstract: A peripherally sealed, juxtaposed, multi-compartment, flexible package is provided which includes a pair of outer walls and at least one separator wall disposed between the outer walls for dividing the package into a plurality of compartments. All of the walls are sealed at a common peripheral terminus, and flowable material is disposed within each of the compartments. The package is adapted to be torn open to simultaneously dispense and admix the flowable material. The multi-compartment dispensing package is manufactured by feeding at least three sheetings of heat sealable flexible film through a first embodiment of form-and-fill packaging instrumentation. A two-compartment dispensing package is manufactured by feeding two sheetings of film through a second instrumentation embodiment including an assembly dividing one sheet into two halves which become outer walls.

A first preferred sealant consists of a resin including by weight: 20.0% Epon 862 novolac epoxy resin; 30.0% SU-2.5 Epon novolac epoxy resin; 20.0% Heloxy 48; 19.5% Epon 826 bisphenol A resin; 10.0% Heloxy 505; and 0.5% silane, and a hardener including: two cycloaliphatic amines, 94.0%; and an aromatic tertiary amine, 6.0%. A second preferred sealant consists of a resin including by weight: 39.5% aromatic epoxide resin; 40.0% Heloxy 48; 20.0% SU-2.5 Epon novolac epoxy resin; and 0.5% silane, and a hardener including: two cycloaliphatic amines, 94.0%; an aromatic tertiary amine, 5.5%; and an amino silane, 0.5%.

Abstract: A package includes opposed flexible sides and a circumferential peripheral seal determining an interior sealed enclosure for storing a material, typically a viscous liquid. The package includes a depending seal which divides the enclosure into a storage reservoir and a dispensing channel in fluid communication. The dispensing channel includes an open upper end and a closed lower end, the upper end being in fluid communication with the storage reservoir, and the lower end being contiguous to the peripheral seal and to an aperture within the depending seal that is adapted to be torn open. Tearing the aperture results in collaterally tearing open the lower end of the dispensing channel and the contiguous portion of the peripheral seal, thereby enabling removal of package contents.

Abstract: A device for repetitively cleaning the tips, edges and blades of dental instruments during prophylaxis. A first embodiment includes two substantially parallel, contiguous rolls made from a rough, absorbent material and attached to an adhesive strip including a lower surface which adhesively attaches to a dental tray. Second, third and fourth embodiments include, respectively, three, four and five substantially parallel, contiguous rolls.

Abstract: Hydro-activated and/or oxygen activated aqueous, enzymatic, antimicrobial dentifrices are stabilized against enzymatic activation prior to oral application of the dentifrice by incorporating a thickener into the dentifrice formulation so as to provide the formulation with an enzyme immobilizing viscosity which inhibits enzymatic action during processing and in the dentifrice package. An illustrative, thickened, enzymatic dentifrice with this enhancement contains glucose oxidase, glucose, lactoperoxidase and potassium thiocyanate together with carboxymethylcellulose in an amount to provide the dentifrice with a viscosity of at least about 800 centipoises.

Abstract: A powdered magnesium composition is mixed with lithium dispersed in an inert, non-water absorbent, liquid medium to produce a substantially homogenous admixture that is heated to melt the lithium and vaporize the liquid medium to thereby obtain a decovered powdered alloy comprising aluminum and lithium. The liquid medium has first and second liquid constituents, wherein the first liquid constituent has a boiling point below the melting point of lithium and the second liquid constituent has a boiling point above the melting point of lithium but below the melting point of the alloy being produced.

Abstract: An orally chewable, enzymatically coated product is provided which, upon chewing, produces an anti-bacterial and bacteriostatic effect in the oral cavity by activation of an enzymatic system contained within the coating. The enzymatic surface coating is developed, in substantially dry form, from a thickened, aqueous coating solution having a viscosity from about 1,000 to about 50,000 centipoises and containing oxidizable substrate and oxidoreductase enzymes specific to such substrate for producing hydrogen peroxide upon oral chewing of the coated product and optionally, but advantageously, further containing peroxidatic peroxidase and an alkali metal salt of an oxygen accepting anion for interacting with hydrogen peroxide to produce oxidized anionic bacterial inhibitor. An illustrative enzymatic system for this purpose contains glucose, glucose oxidase, potassium thiocyanate and lactoperoxidase.
