Abstract
Abstract A device for storage and dispensation of measured quantities of pasty material. The device is formed from two juxtaposed formable sheets including, respectively, a compartment forming a volume housing the measured quantity and a passage forming a duct for ejection of the measured quantity, as well as deformable membrane constituting a sealing mechanism which separates the compartment from the passage. The invention is applicable to packaging and dispensation of measured quantities of a pasty material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
172 words
Device for storage and dispensation of measured quantities of a pasty material, including a housing for the measured quantity of the material and a mechanism for sealing the housing, which is openable for each action of the measured quantity of material, wherein the device comprises: first and second juxtaposed formable sheets having first and second deformations, respectively, extending away from a connection surface joining the first and second sheets wherein the first deformation comprises a compartment forming a volume which houses the measured quantity of the pasty material, and the second deformation in the second sheet comprises a duct for the ejection of the measured quantity of pasty material, wherein the ejection duct is continuously opened at one end thereof and terminates at another end thereof at a position next to the compartment; and said sealing mechanism includes a deformable membrane which separates the compartment from the duct wherein the first and second formable sheets are assembled in at least the peripheral area of the compartment for holding the membrane in place.
Claim 2
Dependent Claim
172 words
Device for storage and dispensation of measured quantities of a pasty material, including a housing for the measured quantity of the material and a mechanism for sealing the housing, which is openable for each action of the measured quantity of material, wherein the device comprises: first and second juxtaposed formable sheets having first and second deformations, respectively, extending away from a connection surface joining the first and second sheets wherein the first deformation comprises a compartment forming a volume which houses the measured quantity of the pasty material, and the second deformation in the second sheet comprises a duct for the ejection of the measured quantity of pasty material, wherein the ejection duct is continuously opened at one end thereof and terminates at another end thereof at a position next to the compartment; and said sealing mechanism includes a deformable membrane which separates the compartment from the duct wherein the first and second formable sheets are assembled in at least the peripheral area of the compartment for holding the membrane in place.
Claim 3
Dependent Claim
41 words
Device for storage and dispensation of measured quantities of a pasty material according to claim 1, wherein the connection surface of the two sheets lies in one plane, and wherein the deformable membrane is a flat membrane lying in said plane.
Claim 4
Dependent Claim
54 words
Device for storage and dispensation of measured quantities of a pasty material according to claim 2, wherein the deformable membrane comprises an extensible film which is, when subjected to the pressure exerted on the pasty material by crushing the compartment, deformable so as to allow the pasty material to flow into the ejection duct.
Claim 5
Dependent Claim
65 words
Device for storage and dispensation of measured quantities of a pasty material according to claim 2, wherein the flat deformable comprises a pre-cut film having a weakened area located in the area of the duct which is torn when subjected to the pressure exerted on the pasty material by crushing the compartment, in order to allow the pasty material to flow into the ejection duct.
Claim 6
Dependent Claim
116 words
Device for storage and dispensation of measured quantities of a pasty material according to claim 3, wherein the deformable membrane has edges, taken in the longitudinal direction of the duct, which are located in immediate proximity to a peripheral area of the compartment, do not form part of the connection between the sheets of formable material and are slidable between said sheets when subjected to pressure exerted on the pasty material when the compartment is crushed, thereby assuming the shape of the duct, said membrane being attached, at an end thereof opposite the duct, to at least the sheet in which the passage is formed, so as to avoid being carried away by the pasty material.
Claim 7
Dependent Claim
49 words
Device for storage and dispensation of measured quantities of a pasty material according to claim 1, wherein the first and second formable sheets and the membrane are assembled together in at least the peripheral areas of the compartment and the duct and wherein the peripheral areas comprise non-deformed areas.
Claim 8
Dependent Claim
52 words
Device for storage and dispensation of measured quantities of a pasty material according to claims 3 or 4, wherein the membrane is attached in the area of the duct to the sheet in which the compartment is formed by an adhesive so as to form a point of attachment which is breakable.
