An aerosol container having a body formed of substantially circular cross-section at the upper end and gradually tapered intermediate the ends thereof and merging with a substantially V-shaped trough at the lower end.

A method for producing a fast drying high solids adhesive and the adhesive composition are described herein whereby a water based polymer emulsion known as latex is modified with unemulsified plasticizing oils and reinforcing-tackifying resins, and a stable final emulsion of polymer, oil and resin is achieved without the use of additional emulsifiers or volatile organic solvents. The method takes advantage of the inherent solubility of the oils and resins in the polymer and of the emulsion-stabi...

A dispensing valve is secured to a standard dome of a pressurized dispenser through a lock ring and a depending plug portion of the dispensing valve housing. The lock ring, around an undercut section on its external radial surface, lies in conforming and compressive engagement with the inner radial surface of a bead which bounds the opening through the dome. The lock ring is forced tightly against the bead by the plug through complementary tapered surfaces of the two. The taper of the lock ring ...

A nylon or similar material ring insensitive to a product stored in a container is disposed imperviously between a valve and the inner wall of the container so as to protect the sealing gasket against chemical reactions with the stored product.

An aerosol package has a container that includes an optimum volume of a gas producing compound, such as an oxidizing compound, without exceeding the potential burst pressure of the container under a worse case scenario. A method for determining the optimum volume of the head space within the container under these conditions and a method for empirically testing the determined volume is described.

A mounting cup for aerosol valves comprising a cupola member having an annular base, means provided said cupola for receiving an aerosol valve, a cylindrical shoulder integral at its bottom edge with the base of said cupola member and concentric with the side of said cupola member so as to form an annular space between said cupola member and said annular shoulder, a ring collar integral with the top edge of said cylindrical shoulder, the peripheral edge of said collar being downwardly curved to ...

A glass container is molded with a recessed outlet end having a sharp outer edge and an enlarged lip. The outside surfaces of the lip of the container from a point adjacent the recessed opening are straight in part and convexly shaped in another part and terminate in a portion of reduced diameter at the neck of the container. A closure assembly centrally housing an aerosol "or pump-type" valve is formed with a depending flange, an annular stepped portion adjoining the central housing, and a conc...

A liquid supply apparatus (10) is provided. The liquid supply apparatus (10) has a cylinder (12), a piston (14) and a piston pushing apparatus. The cylinder (12) is provided with a head portion (20) with outlet (24). The cylinder (12) has a rear end opened. The piston (14) is inserted into the cylinder (12). The piston moves along the longitudinal direction of the cylinder (12) so as to inject liquid contained in the cylinder (12). The piston pushing apparatus (16) pushes the piston (14). The pi...

A vapor permeable pressurized package is disclosed. The package includes a container defining an interior space and a partition dividing the interior space of the container into a first compartment for storing a product to be dispensed from the container and a second compartment for storing a propellant employed to selectively force the product through the outlet of the container. The partition includes pores selectively permitting propellent vapor to pass from the second compartment to the firs...
