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.
Claims4
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.
