Abstract: A unified assembly of a mounting cup and valve stem assembly for aerosol containers. The mounting cup contains a flat central portion having an inner section extending downward from its periphery. An outer section extends upward from the lower edge of the inner section and abuts the inner section. The inner and outer sections constitute the lower wall. The outer section extends above the flat central portion and ends in a channel which can fit onto the bead of an aerosol container. The flat central portion has at least one hole through it. The valve stem assembly contains a flat circular upper piece having holes corresponding to those in the mounting cup. The holes are the open top ends of chambers for springs and plungers. Valve stems are below the chamber. The lower wall of the mounting cup is crimped to hold the mounting cup to the valve stem assembly.

Abstract: An aerosol container containing a propellant and a highly hydrogenated mineral oil lubricant for the lubrication of gaskets in pipe segments. Preferred propellants are normally gaseous hydrocarbons. The preferred lubricant is the compound identified by the Chemical Abstracts Registry No. 8042-47-5. Preferred gaskets are those made of SBR, BR, EPM. And EPDM. A preferred actuating valve is an omnidirectional valve.

Abstract: A stub-out assembly includes a stub-out conduit that defines a major diameter and a minor diameter. The minor diameter defines an attachment groove for receipt of a mount housing and a valve housing. An internal structure such as a multitude of splines, are engageable with an anti-rotation disc within the valve assembly to rotationally fix the valve housing on the stub-out conduit. Another external anti-rotation structure may be achieved through the use of various geometric shapes that interlock or interface with mating geometry located within the quick connect fitting.

Abstract: A flexible tube for use in a water supply system is formed of a material, such as cross-link polyethylene, which bonds best with a relatively flexible plastic. Thus, an end form that is molded or otherwise attached to the flexible tube is typically formed of a relatively flexible plastic; often also cross-link polyethylene. The flexible tubing and its end form is then connected to a housing formed of a second plastic, which is more rigid than the plastic of the end form. A water supply connection is then connected to the second housing through a quick connect fluid connection.

Abstract: An adaptor is threaded to a threaded nipple on a water shutoff valve in a water supply system. The adaptor has a surface for being captured by a quick connect fluid coupling. The quick connect fluid coupling is in turn connected to a flexible tubing. In this manner, the adaptor can connect the flexible tubing to the threaded surface on the nipple of the shutoff valve, such that the existing shutoff valve design can be utilized with flexible tubing having quick connect fluid couplings.

Abstract: A stub-out assembly includes a stub-out conduit that defines a major diameter and a minor diameter. The minor diameter defines an attachment groove for receipt of a mount housing and a valve housing. The mount housing includes a multitude of circumferential fingers which each include a barbed end that engage a corresponding internal groove within the valve housing of the valve assembly. The mount housing fits over the minor diameter and a retainer in the mount housing is aligned with the attachment groove. The retainer includes a partially annular set of conduit attachment legs and a set of housing attachment legs. The conduit attachment legs engage the attachment groove to axially retain the conduit therein. The housing attachment legs each include a barbed end which engage a corresponding surface located within the slot.

Abstract: An overmolded end form for flexible tubing includes windows that are formed to reduce the thickness of the end form, and increase its flexibility. The windows are spaced from each other to provide an area for display of information, such as a logo or part number.

Abstract: A pressure cap assembly snaps onto a stubout tube in a plumbing supply system through a quick connect coupling. The pressure cap assembly may include two parts, with the first part snap fitting to the stubout tube and a second part snap fitting to the first part.

Abstract: The technical field is that of simultaneous dispensing of viscous materials. Many compositions comprise viscous components which must be kept separate until they are used. Known methods of application of separate components do not guarantee proper ratios. This invention solves this problem by presenting a single aerosol container (4) having a multi-valve body (8) wherein the valves (10, 12) are activated by a single actuator (26) and the viscous materials are kept separate until used. The system (2) may use multiple collapsible bags (16), a barrier liner (42), a dip tube (46), and a spray-any-direction valve (50) having an omnidirectional attachment (60) which contains a check valve container (122) made up of a constricted lower end (132), a top surface (134), a lateral opening (136), and a check ball (138) for opening and closing passageways.

Abstract: An aerosol solvent weld cement composition for joining ends of plastic pipe. The composition contains at least one polymer capable of welding the plastic pipes to each other, at least one solvent for the polymer, and at least one propellant for the polymer/solvent solution. The composition is maintained under pressure greater than atmospheric pressure in an aerosol container. A female omnidirectional valve is disclosed for use in the aerosol container. This valve allows the solvent weld cement composition to be applied to pipes from any angle.

Abstract: A dispenser for simultaneously dispensing at least two viscous materials to be mixed. The dispenser contains an outer cartridge and an inner container. The cartridge has an open rear end having a rear thrust wall which will be pushed forward by the conventional dispensing gun. The cartridge has a front end containing a nozzle for connecting with a mixing nozzle. The container extends from the front end to the rear end and is made of telescoping sections. Viscous materials are present within the container and in the space between the wall of the container and the wall of the cartridge. As the rear thrust wall is pushed forward. the telescopic sections are captured in recesses of the rear thrust wall. More than one concentric container may be present.

Abstract: A collapsible dispensing system for viscous fluids which should not be mixed until the time of application. The system comprises a cartridge and a container which fits into the cartridge. The cartridge is designed to fit into conventional caulking guns. The cartridge has a forward end cap having a central circular orifice and a rear thrust wall. The container fits into the cartridge and is made up of a plurality of collapsible chambers which hold the viscous fluids. The chambers may take the form of closed bags or accordion cylinders. At the front end of each chamber is a forward end piece. The forward end pieces fit snugly together and form a circular periphery. The forward end piece contains a neck which fits through the forward end cap and attaches to a mixing nozzle. Chambers having predetermined ratios of ingredients may be used in this system.
