Single Dose Dispensing Package

Abstract

A single dose dispensing package (100) having a backing (102) for maintaining the package in a substantially flat orientation is disclosed. A score (106) through the backing allows the package to open upon flexure. At least one additional score on the opposite side provides at least one metered opening in the package. Absorbent material (112) placed over the score, and adhered to the dispensing package only in the area of the score, provides controlled dispensing and application of the contents using essentially an entire surface of the absorbent material as an applicator.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of provisional U.S. patent application No. 60 / 955,918, filed Aug. 15, 2007, and provisional U.S. patent application No. 60 / 947,730, filed Jul. 3, 2007.FIELD OF THE INVENTION[0002]The present invention generally pertains to single dose packaging of one or more compositions, and to dispensing packages further comprising an applicator for the one or more compositions.BACKGROUND OF THE INVENTION[0003]Various designs have been used to package different types of compositions. Prior devices, however, generally have been unable to provide packages that are capable of dispensing liquids, gels, creams, dispersions, pastes and other types of fluid and semi-fluid compositions in a controlled and easy to use fashion. In addition, many packages require the use of two hands to open the package. Further, many packages require fine dexterity or the use of fingernails to peel off coverings to access the contents of the p...

AI Technical Summary

Benefits of technology

[0005]The present invention is directed to an economical, easy to use dispensing package that contains one or more reservoirs of a composition. In embodiments containing two or more reservoirs of a composition, the compositions can be incompatible, either physically or chemically. The contents of the reservoirs are dispensed onto an absorbent material when the dispensing package is opened, and essentially an entire surface the absorbent material acts as an applicator for simultaneous application of the compositions. After the dispensing package is opened, and the contents of a reservoir is released, the absorbent material remains attached to the remainder of the dispensing package for ease of application to a surface, for example, human skin. In embodiments wherein two or more reservoirs of compositions are present, the compositions can be applied directly to the skin in the absence of an applicator.

[0006]In one embodiment, the present invention is directed to a package for compositions and dispensing the compositions through at least one opening, said package comprising a backing of sufficient rigidity to maintain the package in a substantially flat configuration; a first score formed extending at least partially into a first side of the backing; a coating formed on a second side of the plastic backing having an elastic limit that is greater (i.e., is more flexible) than the elastic limit of the backing; a pouch formed on the second side of the backing that is adapted to hold the contents of the package; and at least one second score extending from an interior portion of the pouch and at least partially into the second side of the backing, the at least one second score substantially aligned with the first score on the backing such that flexure of the backing by a first amount is sufficient to cause the backing to exceed the first elastic limit and break along the first score, while flexure to a folded position is insufficient to cause the coating to exceed the second elastic limit.

[0007]In another embodiment, the present invention is directed to a package for two or m

Problems solved by technology

Prior devices, however, generally have been unable to provide packages that are capable of dispensing liquids, gels, creams, dispersions, pastes and other types of fluid and semi-fluid compositions in a controlled and easy to use fashion.

Opening these types of packages requires additional time, and may require skills not possessed by various segments of the population.

Prior devices also have been unable to easily and economically allow the simultaneous application of two or more incompatible compositions.
