Abstract: A blow molding apparatus is provided including a blow mold, an extrusion apparatus, a locator mechanism, and a blow pin. The blow mold has first and second blow mold halves which are engageable and disengageable with one another. The first and second blow mold halves define first and second inner cavities when the mold halves are engaged. The first cavity has a first shape and the second cavity has a second shape which differs from the first shape. The extrusion apparatus has a die head through which a parison is extruded. The locator mechanism is associated with one of the blow mold and the extrusion apparatus for changing the positioning between the blow mold and the die head to allow capture of an extruded parison by the first and second mold halves within a desired one of the first and second inner cavities such that the extruded parison can be formed into an article having substantially the same shape as the desired cavity.

Abstract: Disclosed is a translucent prespotting composition containing a single phase liquid microemulsion at the processing temperature. The single phase microemulsion comprises a gelling agent, one or more surfactants, a water immiscible solvent or a mixture of water immiscible solvents which may contain no more than about 2 weight percent water at 25.degree. C. when the organic solvent is saturated with water in absence of surfactants or other additives, and water in amounts greater than about 15 percent by weight and less than about 60 percent by weight of the composition. The microemulsions before gelling or solidifying may be oil continuous, water continuous, or bicontinous.

Abstract: This invention relates to a trigger sprayer dispenser which can be used to dispense liquids in multidirections. The present invention incorporates a mechanism in a conventional trigger sprayer to allow the sprayer to be used in an inverted position without the dispenser contents leaking through a sprayer vent orifice. The mechanism comprises a by pass chamber in communication with the chamber of the dip tube. The by pass chamber then creates an auxiliary fluid path to the dip tube fluid path when the dispenser is inverted. When the dispenser is inverted, the fluid remaining in the dip tube acts as a fluid lock thereby preventing internal dispenser air from escaping out from the dip tube into the trigger sprayer. The by pass mechanism therefore, also allows for more efficient evacuation of the dispenser contents.

Abstract: This invention relates to a spraying apparatus comprising a detachable refill pouch said pouch designed to contain fluid, and a sprayer device detachably connected to the refill pouch and a receptacle device held therebetween the refill pouch and sprayer. The pouch is held in place by detachably connecting the pouch directly to the sprayer with the receptacle held therebetween. The pouch has a neck portion made of material to provide sufficient integrity to allow for mounting of the neck to a cap on a sprayer.

Abstract: Disclosed is an improved reducing solution comprising: a) from about 1.0% to about 11.0% by weight of cysteamino hydrochloride; b) from about 1.0% to about 24% by weight of a reducing agent selected from a group consisting of salts and esters of thioglycolic acid, L-cysteine, thiolactic acid, and thiomaleic acid, dithioerythreitol, and dithiothyreitol; c) from about 0.5% to about 7% by weight of isoascorbic acid; d) a base in amounts sufficient to adjust the pH from about 6.5 to about 8.5; and e) water in amount sufficient to total 100 percent of the solution; the weight percents being based upon the total weight of the solution.

Abstract: Self-building laundry detergents are organic polyamine amides, which contain a plurality of carboxylate radicals and an amide ester. These compounds are useful individually as detergents or as components in detergent compositions.

Abstract: Free edge-sealed film articles and a method for making such, wherein the articles comprise a plurality of film portions and contain a free edge-seal between two of such portions, with one or both of the two free edge-sealed portions consisting essentially of a plurality of layers of diverse thermoplastic materials which are so ordered that on sealing the two portions together, the ordered layered film portion is curled toward the other of the two free edge-sealed portions.

Abstract: A battery operated hand-held dispenser which operates efficiently at lower power levels than prior art devices. The dispenser as included therein has spray, foam or stream, dispensing capabilities coupled with pump mechanisms, vent mechanisms and positive closures.

Abstract: A process for forming a reclosable closure profile, wherein the configuration of the closure profile is mechanically altered and, while mechanically confined, is simultaneously cooled.

Abstract: Disclosed is a zipper for a reclosable thermoplastic bag having opposing rib and groove profiles wherein at least one of the opposing zipper profiles has an longitudinally extending part interlockable and substantially free of interdigitation with the opposing profile and wherein the part is structurally discontinuous along its length. When the rib and groove profiles are interlocked, an audible clicking sound and/or a vibratory or bumpy feel perceptible to the touch is imparted.Further disclosed is a process and apparatus for making the zipper wherein a zipper profile is extruded and indentions are formed within and along it.

Abstract: Disclosed are a process and apparatus for eliminating the problem of color contamination during product recycle in the manufacture of reclosable thermoplastic bags having zippers of a color different than that of the remainder of the bag. Process and apparatus for effecting same include extrusion of the colored thermoplastic material from a separate, smaller secondary extruder to avoid process shutdown during recycle, encapsulation of the colored thermoplastic material within the colorless flow melt to enhance transport of the colored flow melt, and placement of a dump valve between the secondary extruder and the feedblock to controllably interrupt the flow of the colored flow melt as desired. Further disclosed are an apparatus and process for effecting encapsulation of the colored flow melt.

Abstract: A hand held, dip-tube style liquid spray dispenser comprising a container having an inclined bottom, sidewalls extending upwardly from the bottom, and an upper end, a dispensing device positioned adjacent this upper end for dispensing a liquid held in the container and communicated upward to the dispensing device, and a tube for communicating liquid upward from a lower end of the tube to the dispensing device. The tube being of a sufficient length such that the lower end of the tube is urged toward the lowermost portion of the bottom when the container is oriented as in use.

Abstract: A dispensing package for dispensing discrete portions of a vaporizable material in the form of prewetted absorbent pads, wherein the dispensing package broadly comprises a container and a plurality of such absorbent pads. The absorbent pads are closely stacked within the container, and generally comprise an absorbent pad portion with a flexible film backing which is resistant to permeation of the vaporizable material therethrough, and a collapsible tab- or ring-like structure joined to the backing opposite the absorbent pad portion. In other embodiments, the absorbent pad portion is preferably sub-divided into sub-portions having different fluid absorbing characteristics, which sub-portions are separated by the same flexible film as used in the backing, and less than all of the sub-portions are initially prewetted with the vaporizable material or are prewetted with different materials.
