Abstract: In a preferred embodiment, a system for dispensing semi-liquid materials in predetermined ratios, which system includes two cartridges having the same or selected different diameters, but proportional to the ratio of the materials to be dispensed, the cartridges being rigidly snapped together by interfitting male and female elements. In another aspect of the invention, there is provided a seal for a cartridge for dispensing semi-liquid material which seal includes a resilient wiping lip formed around the outer periphery of the seal which is forced against the inner surface of a cartridge by the flattening of the convex face of the seal.

Abstract: Apparatus for dispensing of beverages contained in deformable bottles, particularly family-size conventional PET bottles of more than one brand or taste. The apparatus comprises a housing with one or more beverage dispensing valves at the outside, an openable lid, and one or more pressure vessels with openable lid(s) thereinside. Each pressure vessel is configured to receive one or more of the bottle(s) in an upright position. A fitting is mountable to the bottle(s), and is extended by a conduit leading to the respective dispensing valve(s). Air pressure introduced into the vessel(s) cause the squeezing of the bottle(s) thereunder following discharge of the contents of the respective bottle(s) through the dispensing valve.

Abstract: A dosing unit for concentrate in a post-mix beverage dispenser is described which includes an enclosed cylinder space, and a pump piston with a bore running parallel with the axis. A control piston which is in contact with the input side shutoff of the cylinder space is disposed within and movable longitudinally of the bore in the pump piston. The control piston includes an intake opening, and in contact with the pump piston, forms an outlet opening, where the intake and the outlet openings are alternately opened or closed through axial movement of the control piston with respect to the cylinder space and the pump piston. The control piston movement is restricted with respect to the accelerator piston and constrained by axial impact points, so that an axial movement forced upon the control piston causes an impulse in both directions to open or close the intake or the outlet openings, after which by carry-over of the particular impact, the pump piston is moved axially the same distance.

Abstract: A self-closing push-pull top for a bottle includes a threaded collar adapted to engage a threaded bottle neck. A hollow stem extends from the threaded collar and engages a cylindrical guide aperture of a cap. The cap is slidable along the hollow stem about the guide aperture to a first position in which the hollow stem and the cap are positioned with respect to one another to prevent fluid flow from the bottle. The cap is further slidable along the hollow stem about the guide aperture to a second position in which the hollow stem and the cap are positioned to allow fluid flow therethrough. A biasing member is provided for biasing the cap in the first position. Since the cap is biased in this first position, it normally remains closed. Upon application of working pressure, the biasing member deforms to allow the cap to slide to the second position in which fluid may be dispensed from the bottle.

The removable container, which itself is comprised of top and bottom portions, is adapted to hold a tube of toothpaste therein. Additionally, one portion of the removable container can be adapted to hold and dispense dental floss and to be used as a cup.

Abstract: The trigger operated pumping mechanism for a fluid dispensing device comprises a body. The pumping mechanism comprises a cylinder in the body of the dispensing device, a piston received in the cylinder, a trigger movably mounted to the body and having a front side and a back side, and being coupled to the piston, and a non-metal biasing mechanism for biasing the trigger away from the body to bias the piston coupled to the trigger out of the cylinder. The biasing mechanism includes a separate, non-coiled elongate, generally flat, spring having elongate, opposed flat surfaces and opposite ends and being positioned between the body and the trigger. The trigger back side has a back wall. The spring has one flat surface of one end portion at one end of the spring positioned adjacent the back wall of the trigger and has the other end of the spring positioned rearwardly of the trigger and engaging against the body.

Abstract: A projectile for releasing a gas or other suitable fluid to initiate operation of an inflator in a motor vehicle inflatable safety system. In one embodiment, the projectile has a plurality of intersecting, concave, and inclined faces which taper to a point at the tip of the projectile. This projectile is positioned on the convex side of a dome-shaped disk which isolates the inflator from an expandable confinement. When a condition is detected requiring operation of the inflator, the projectile is freely propelled toward the disk to controllably separate the disk along lines coinciding with the edges defined by the intersecting faces of the projectile to reduce the potential for portions thereof breaking or tearing off and entering the flow from the inflator to the confinement.

Abstract: A bulb actuator for a dropper closure wherein an overcap is mounted on the dropper closure. A bulb squeeze member is slidably mounted in the overcap and has a pair of fingers engaging and straddling the bulb. The fingers are cammed inwardly to squeeze the bulb when the bulb squeeze member is pressed inwardly of the overcap.

Abstract: Methods of and apparatus for adding toner to an electrostatographic development station from a flat-flanged container containing toner minimizes spillage of toner by automatically uncovering and recovering the container. The flat-flanged container has a mouth surrounded by a peripheral flange which is covered by a flexible cover folded upon itself and adhered to the flange. A slide cover is slidably mounted on the flange with the flexible cover attached at one end to the slide cover. The container is emptied by inserting the container into a sump lid positioned over a hopper within the electrostatographic development station and moving the container so that the mouth of the container is in alignment with an opening through the sump lid. As the container is moved into alignment with opening, the slide cover is automatically removed from the container simultaneously peeling the flexible cover from the flange and opening the container to empty the toner.
