Abstract

Abstract The invention relates to a composite dispenser for materials in paste form which are intended to be admixed with a diluent prior to use, comprising a flexible container consisting of a lower material-containing section and of an upper section forming an open receptacle when separated from the lower section by a perforable wall whereby, after perforation, application of pressure upon the lower section will cause a controlled quantity of the material contained therein to be dispensed through the perforation into the upper receptacle for admixture in situ with a suitable diluent.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 170 words
A composite container-dispenser for holding small quantities of coloring paste adapted to be diluted prior to use comprising in combination: a central paste container made from deformable material; a flat annular zone surrounding an opening of the central container; cylindrical sides contiguous with said annular zone forming a shallow cup; a disk having a diameter slightly smaller than the internal diameter of the cup adapted to form an air-tight seal across the opening of the central container and prevent the paste contained therein from drying; the disk having an opening means to allow a desired quantity of paste to be squeezed out of the central container into the area of the shallow cup so that the paste can be diluted in said cup; the material remaining in the cup area after use being adapted to form a film which re-closes the preformed opening and prevents air from coming into contact with the paste material remaining in the central container; and a frusto-conical main body integrally formed with said cylindrical sides.
Claim 2
Dependent Claim 170 words
A composite container-dispenser for holding small quantities of coloring paste adapted to be diluted prior to use comprising in combination: a central paste container made from deformable material; a flat annular zone surrounding an opening of the central container; cylindrical sides contiguous with said annular zone forming a shallow cup; a disk having a diameter slightly smaller than the internal diameter of the cup adapted to form an air-tight seal across the opening of the central container and prevent the paste contained therein from drying; the disk having an opening means to allow a desired quantity of paste to be squeezed out of the central container into the area of the shallow cup so that the paste can be diluted in said cup; the material remaining in the cup area after use being adapted to form a film which re-closes the preformed opening and prevents air from coming into contact with the paste material remaining in the central container; and a frusto-conical main body integrally formed with said cylindrical sides.
Claim 3
Dependent Claim 38 words
The composite container-dispenser as claimed in claim 1, wherein the disk is formed of two layers of equal diameter, the opening means comprises a preformed opening in a first layer and a second upper layer without an opening.
Claim 4
Dependent Claim 28 words
The composite container-dispenser as claimed in claim 1, wherein the opening means comprises a small preformed opening in the disk which is closed with a removable adhesive tab.
Claim 5
Dependent Claim 29 words
The composite container-dispenser as claimed in claim 1, wherein the opening means comprises a hollow upwardly-extending integral portion in the disk which can be cut to dispense the paste.
