Abstract: A stabilized and extrudable paste or gel dentifrice comprises two dentifrice portions, each of which includes a component which is chemically reactive with the other such component in the other portion, with the portions being maintained separate from each other in a dispensing container from which they are dispensable together through a closable opening therein in response to pressure. One of the reactive components is an alkali metal fluorine-containing salt such as sodium fluoride or sodium monofluorophosphate, used for its effect in hardening tooth enamel, and the other is a water insoluble calcium salt, such as dicalcium phosphate, tricalcium phosphate or calcium carbonate, used as a polishing agent. The dentifrice portions are preferably separated by an extrudable material, such as a polyhydric alcohol-water gel of a gum, such as sodium carboxymethyl cellulose. Also within the invention is a method for the manufacture of the mentioned dentifrice.

Abstract: An improved animal food wherein synthetic proteins comprise all or a significant part of the protein content of the animal food. The animal food is characterized by a high degree of palatability and high nutritional and caloric value.

Abstract: A bleaching composition and method utilizing a percompound, an acyl-alkyl ester, and an ester-hydrolyzing enzyme, the ester and the enzyme being adapted to react to form an activator for the percompound.

Abstract: A device for confining an aerosol spray containing a deodorant or antiperspirant to the axilla area, including a tubular shield which is separably coaxially coupled to the spray end of an aerosol container provided with an axially directed spray nozzle and a depressible valve actuating lever. An opening is formed in the proximate section of the shield to provide finger access to the valve actuator. The edge of the discharge end of the shield may be contoured to mate a corresponding border of the axilla area and the proximate borders of the shield may be shaped to engage aerosol containers of various configurations.

Abstract: A shield device for restricting the spray from an aerosol container to a limited area used in applying an antiperspirant or deodorant to the axilla, which includes a sleeve releasably coupled to the top of and projecting above an aerosol container having an axial upwardly directed nozzle and a concentric depressible valve actuator. A frustoconical tubular shield member is coaxially supported by the sleeve for downward movement to depress the valve actuator, and projects above the sleeve and is releasably lockable in its raised position. By pressing the upper edge of the shield member against the axilla, the valve is depressed and opened.

Abstract: A spray confining aerosol dispensing device includes a pressurized aerosol container provided with an upwardly directed discharge tube coupled to a coaxial spray nozzle having a venturi shaped bore to effect the divergence of the spray. An axially movable spray confining tubular shield having an end discharge opening slightly greater than the spray pattern at such opening projects axially from the container, and axial depression of the shield effects the depression of the container valve actuator to open the valve. In one form the shield is alternatively movable to an extended operative position and to a contracted inoperative position with the container telescoping the shield and in another form the shield carries the venturi nozzle on a transverse wall so that the shield may be alternatively employed as a closure cap or a valve actuating spray confining shield.

Abstract: A spray confining aerosol dispensing device, includes a pressurized aerosol container provided with an upwardly directed axial nozzle on its top wall and a valve actuator including a pair of depressible opposite radial arms extending beyond the container periphery. A shield sleeve slidably engages the container and is horizontally rotatable and vertically movable between upper and lower positions. A pair of peripherally spaced ribs are formed on the sleeve inside face and are above the actuator arm level when the sleeve is extended, so that the sleeve may be rotated to bring the ribs in vertical registry with the actuator arms. Depression of the sleeve when pressed against a surface to be sprayed, opens the spray valve and the spray is confined by the sleeve. Stop members are provided on the sleeve to limit its axial movement on the container.
