Abstract

Abstract A container for storing and dispensing products is disclosed which features a substantially fluid-tight seal for preventing or inhibiting the loss of any volatile component(s) contained in the product and/or for preventing air, water vapor, microorganisms or other agents which might adversely affect the product from freely coming into contact therewith. The container of this invention is especially adapted for storing and dispensing a solid or semi-solid cosmetic product containing at least one component which is relatively volatile and/or susceptible to chemical and/or microbial spoilage and comprises: (a) a base member provided with a chamber for storing product; (b) a cover member; and, (c) a laterally compressible sealing means disposed between a downwardly projecting rigid element associated with or forming part of the cover member and an upwardly projecting rigid element associated with or forming part of the base member or chamber, the sealing means extending continuously about the chamber such that when the base member is in closing engagement with the cover member, the downwardly and upwardly projecting rigid elements cooperate to subject the sealing means disposed therebetween to a substantially fluid-tight lateral compression.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 180 words
A container for storing and dispensing a solid or semi-solid product containing at least one component which is relatively volatile and/or susceptible to chemical and/or microbial spoilage which comprises: (a) a base member provided with a chamber for storing the product, said chamber having a rigid, continuous, upwardly projecting wall; (b) a cover member connected to the base member by a hinge, said cover member having a rigid, continuous, downwardly projecting element extending continuously about the upwardly projecting wall of the chamber; (c) locking means for maintaining the base member in closing relationship with the cover member; and, (d) a resilient, laterally compressible gasket or O-ring member extending about the exterior wall of the chamber within a peripheral groove or channel defined therein and positioned below the upper edge of the chamber wall, a substantially fluid-tight seal resulting when the base member, being in closing engagement with the cover member, causes the upwardly projecting rigid wall of the chamber to cooperate with the downwardly projecting rigid element or exert a lateral compressive force against the gasket or O-ring disposed therebetween.
Claim 2
Dependent Claim 180 words
A container for storing and dispensing a solid or semi-solid product containing at least one component which is relatively volatile and/or susceptible to chemical and/or microbial spoilage which comprises: (a) a base member provided with a chamber for storing the product, said chamber having a rigid, continuous, upwardly projecting wall; (b) a cover member connected to the base member by a hinge, said cover member having a rigid, continuous, downwardly projecting element extending continuously about the upwardly projecting wall of the chamber; (c) locking means for maintaining the base member in closing relationship with the cover member; and, (d) a resilient, laterally compressible gasket or O-ring member extending about the exterior wall of the chamber within a peripheral groove or channel defined therein and positioned below the upper edge of the chamber wall, a substantially fluid-tight seal resulting when the base member, being in closing engagement with the cover member, causes the upwardly projecting rigid wall of the chamber to cooperate with the downwardly projecting rigid element or exert a lateral compressive force against the gasket or O-ring disposed therebetween.
Claim 3
Dependent Claim 20 words
The container of claim 10 wherein the gasket or O-ring is held within the groove or channel under elastic tension.
Claim 4
Dependent Claim 15 words
The container of claim 1 wherein the chamber is sealed with a removable barrier film.
Claim 5
Dependent Claim 17 words
The container of claim 3 wherein the barrier film is a laminate of metal on synthetic resin.
Claim 6
Dependent Claim 18 words
The container of claim 1 wherein the chamber for storing the product is integral with the base member.
Claim 7
Dependent Claim 22 words
The container of claim 1 wherein the chamber for storing the product is separate from the base member and is bonded thereto.
