Abstract: Device for applying liquid materials to the skin, said device having a liquid container, a poromeric plastic applicator head, and a diaphragm spring holding the applicator in said device. The diaphragm spring provides a liquid tight seal between the poromeric applicator head and the liquid container and also allows movement of the poromeric applicator head in a vertical direction to create a pressure within the liquid container and provide force to aid in moving the liquid through the poromeric applicator head to its outer surface. The poromeric applicator head is also provided with a capillary pressure compensating valve to maintain substantially equal pressure within and without the dispensing container.

Abstract: A flexible package preferably comprised of paper and having an opening system that controls and reduces the initial removal forces required to withdraw the compressed flexible articles from the package after the opening device portion of the system has been activated. A reinforcement sheet located at the lowermost end of the opening system protects the flexible articles contained within the package prior to activation of the opening device, and provides additional support for the package prior to opening. A substantially vertically oriented line of weakness located in the reinforcement sheet ruptures automatically when the opening device is activated permitting the flexible articles to fan out further from the package. This automatic rupturing of the reinforcement sheet reduces the compressive forces acting upon the compressed flexible articles. This in turn permits easier removal of the first few flexible articles from the package either one at a time or in multiples.
Abstract: A squeeze bottle foam dispenser with improved foam consistency throughout the range of manual squeeze conditions. The foamer includes a pressure operated valve for simultaneously restricting flow of the compressible and incompressible fluids until a predetermined threshold pressure is developed within the bottle by manual deformation thereof. Thus, foam is not dispensed from the container until a pressure is developed within the bottle sufficient to produce a desirable foam. The disclosed foamer is for storage and operation in the inverted orientation. This avoids the necessity of an extended spout and its concomitant problems.
Abstract: A child resistant box which is composed of a base, a lid and a hinge connecting the base and lid together. A latching mechanism is located on each of the two sides of the box for releasably retaining the lid to the base. The box can be moved between open, intermediate, and closed positions. The box also includes a means for biasing the lid from the intermediate position toward the closed position. To open the box the lid is compressed to the intermediate position. In this intermediate position, the latching mechanism may be disengaged by exerting manual pressure thereon toward the center of the box. Once pressure is exerted simultaneously on both latching mechanisms the lid is released and the biasing means moves the lid at least partially toward the open position. The operation of this box is particularly well-suited for the elderly.

Abstract: A container for housing granular materials and a blank for forming the container. The container is a six sided enclosure including a top wall, a back wall, a bottom wall, a front wall and two end walls. The front wall has an inner layer and an outer layer. The outer layer has a transverse tear strip therein and is attached to the inner layer below this tear strip. A glue flap is attached to the interior surface of the top wall and also attached to the top edge of the inner layer of the front wall along a perforated cut line. This configuration prevents the granular material from migrating between the layers of the front wall during shipping. Each end wall is comprised of several layers. Included are two main layers which together have a top edge. A tear strip panel extension is attached to the main layers below the tear strip. An ear is attached to the tear strip panel extension above the tear strip and also attached to the top wall.

Abstract: A dispensing package which automatically relieves residual pressure on a cream product and dispenses this product in incremental doses is disclosed. The package uses a feed screw to drive an elevator which impels the cream product in a unidirectional manner. The drive of the feed screw is superimposed with reciprocatory motion caused by internal cams which retract the elevator. By intermittently retracting the elevator a suitable distance, discrete amounts of the product are dispensed for each cycle and the residual pressure on the product is relieved, preventing it from weeping onto the applicating surface of the dispenser. The dispensing package is well suited to contain and dispense cream deodorants and antiperspirants.
