Abstract
Abstract A dispersing valve comprises a disc having a sinuous slit which is cut at an angle with respect to the face of the disc to form at least two, and preferably three, valve members, one of which is larger than the other one or two and is designed to permit passage of fluid when the container to which the valve is attached is compressed. The at least one other valve permits excess fluid and air to return to the interior of the container when it is released. The multiple valve arrangement is formed by the angular nature of the slit, permitting highly efficient dispensing and resealing action.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
A multiple valve structure comprising a planar body of resilient material; and a continuous, nonorthogonal cut extending through said body from one major surface thereof to the other major surface thereof, said cut opening at one major surface in a first line having a generally sinuous pattern and having at least two lateral reversals in direction in the plane of said one major surface, said cut opening at the other major surface in a second line having a generally sinuous pattern and having at least two lateral reversals in direction in the plane of said other major surface, and the lateRal excursions of said first line being significantly greater than the lateral excursions of said second line, each of said excursions forming an independently operable valve member, adjacent ones of said valve members being operable by fluid pressure applied to opposite major surfaces of said planar body.
Claim 2
Dependent Claim
147 words
A multiple valve structure comprising a planar body of resilient material; and a continuous, nonorthogonal cut extending through said body from one major surface thereof to the other major surface thereof, said cut opening at one major surface in a first line having a generally sinuous pattern and having at least two lateral reversals in direction in the plane of said one major surface, said cut opening at the other major surface in a second line having a generally sinuous pattern and having at least two lateral reversals in direction in the plane of said other major surface, and the lateRal excursions of said first line being significantly greater than the lateral excursions of said second line, each of said excursions forming an independently operable valve member, adjacent ones of said valve members being operable by fluid pressure applied to opposite major surfaces of said planar body.
Claim 3
Dependent Claim
37 words
A structure according to claim 1 wherein the valve member formed by one excursion of said first and second lines is characterized by a significantly greater surface area than the valve member formed by an adjacent excursion.
Claim 4
Dependent Claim
27 words
A structure according to claim 1 wherein said cut extends through said body at an angle of between 20* and 70* with respect to said major surfaces.
Claim 5
Dependent Claim
16 words
A structure according to claim 1 wherein each end of said cut lies within said body.
Claim 6
Dependent Claim
27 words
A structure according to claim 1 wherein each of said first and second lines forms a sawtooth pattern in which each lateral reversal is an acute angle.
