Abstract

A combination mold and carrier for seamless suppositories. The dispenser has an elongated rectangular one-piece body of a flexible material that is dimensionally stable at ordinary temperatures. A plurality of suppository cavities of uniform constant tapers with rounded bottoms are formed in tubular members extending from the top side of the body. The body side surfaces are tapered with circular cross sections concentrically with the cavities. These side surfaces merge together adjacent the topside and separate into the individual tubular members towards the bottoms of the cavities. The cavities have rounded bottoms to facilitate ejection of suppositories by a manual pinching action. A circular flat base formed on the rounded walls support the body upright on a work surface with the cavities upright to receive a suppository mixture. A rectangular cover with open ends can be slideably mounted over the body in a telescoped relationship. In addition, the body can have identical cavities or cavities varying in axial dimension so that identical and graduated doses can be provided in the suppositories from the same medicinal casting compound.

Dependent claims

A combination mold and a carrier for suppositories, comprising:

(a) an elongated rectangular body of flexible material that is dimensionally stable at ordinary temperatures;
(b) said body having a width substantially less in dimension than in height, and a length substantially greater than both its width and height;
(c) said body having parallel planar top and bottom surfaces, and tapered side surfaces that merge together adjacent said top surface and separate into individual tubular members as they extends towards said bottom surfaces;
(d) a plurality of tapered cavities formed side-by-side within said body and said cavities uniformly spaced laterally along said top surface and extending axially in a uniform constant taper within each tubular member through said body towards said bottom surface;
(e) said cavities each having rounded walls defining a rounded bottom of said cavities to facilitate suppository ejection from each cavity by a manual pinching action upon said rounded walls and said tubular members, said rounded bottom beginning in curvature at a predetermined dimension above said bottom surface of said body whereby said volumetric capacity of each cavity can be adjusted;
(f) said rounded walls at their apex carrying flat supporting bases in parallel to said top surface to receive a suppository mixture downwardly into said cavities;
and
(g) said rounded walls connected by tubular walls to said top surface and said tubular walls about said cavities forming a common wall of uniform thickness between said cavities in said body.
