Abstract: An applicator for fluid products includes a bottle enclosed by a cap having a partition defining in the cap an enclosed chamber. The partition includes an aperture which forms a passage between the enclosed chamber in the cap and the interior of the bottle. Rotating the cap for assembly to the bottle will place this passage in an unoccluded condition. As the bottle is inverted or shaken prior to use, the fluid contents of the bottle will travel through the passage and into the enclosed chamber in the cap. As the cap is rotated for removal from the bottle, a valve element will occlude the passage, trapping the fluid in the cap. Squeezing the cap to deform the sidewalls will force the fluid through a narrow bore in a supply stem leading to a dispensing tip.

Abstract: A dispenser for smoothly and reliably dispensing flowable or particulate matter such as fish food is provided, in which dynamic gravity of the matter itself is utilized to regulate dispensing of the same in an uncomplicated manner. The dispenser has a container adapted to be mounted upon a rotatable shaft and having a hollow interior with two openings therethrough for communicating with external surroundings. A partition is mounted within the container interior for dividing a portion of the container interior into a plurality of compartments. The partition extends between the openings to limit quantity of matter falling into one of the compartments as the container rotates. A duct is mounted to rotate with the container and communicates with one of these openings. As the container rotates, the partition regulates the quantity of matter falling into the dispensing compartment and directs matter not discharged from the dispensing compartment back into the other compartment.

Abstract: A replaceable cartridge for a dispenser comprises an elongated collapsible envelope for containing the material to be dispensed. The cartridge includes a tubular body portion and two end walls which are of one-piece with the tubular body portion. The cartridge is constituted by a thin-walled, flexible, limp and collapsible material. A cap portion having a discharge outlet faces one end wall of the cartridge, and a movable compression disc faces the other end wall of the cartridge. In response to movement of the disc, the cartridge is collapsed to thereby cause rupture of the end wall adjacent the discharge outlet. Alternatively, a puncture needle is provided on the cap portion for puncturing the end wall adjacent the discharge outlet. Once opened, the material within the cartridge is free to escape through the discharge outlet in response to such movement of the disc.

Abstract: A dispenser unit includes a container formed from a tubular member having a constant transverse cross-sectional configuration which is adapted to contain an extrudable material. One end of the tube is closed by an end wall having a discharge nozzle therein which can be selectively sealed by a closure cap. The other end of the tubular member is sealed by an air-tight end wall. Disposed within the tubular member is a compression arrangement which includes a threaded shaft adapted for rotational non-longitudinal motion within the tubular member and a compression element mounted on the shaft and adapted for longitudinal motion within the tubular member when the threaded shaft rotates to exert an expelling or compression force on the extrudable material. An operating structure adapted for longitudinal non-rotational reciprocating motion on a support associated with the container has an idle position and an actuated position, and is constantly urged to its idle position.

Abstract: A plastic film mirror is formed by attaching a highly reflective, metallized polyester film to a frame having a rigid base section and a resilient upper section capable of bending inwardly towards the interior of the mirror, and subjecting said film to an elevated temperature for a specific period of time to cause the film to shrink in at least one direction. The shrinking of the film urges the resilient upper section of the frame inwardly thereby causing said film to be maintained in a state of constant tension by the restoring tendency of the resilient upper section. The plastic film mirror may be further provided with a means for modifying the reflective characteristics of a portion of the mirror. The means preferably comprises a shallow dish located behind the mirror which when evacuated draws the reflective film inward and thereby causes a concave indentation.
