Abstract
Abstract An apparatus for measuring and dispensing liquid is provided by the combination of a reservoir container having a flexible wall and measuring and dispensing means disposed on the reservoir container. The measuring and dispensing means comprises an outer wall member and an inner wall member, the inner wall member being disposed within the outer wall member and spaced therefrom to define liquid passage means between the outer wall member and the inner wall member, and the inner wall member defines a measuring chamber therewithin. Liquid passage means are provided in liquid communication with the liquid passage and the measuring chamber, and conduit means are disposed in the reservoir container and in liquid communication with the liquid passage means.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
129 words
Apparatus for measuring and dispensing liquid comprising a reservoir container having a flexible wall; measuring and dispensing means disposed on said reservoir container, said measuring and dispensing means comprising an outer wall member and an inner wall member, said inner wall member being disposed within said outer wall member and spaced therefrom to define liquid passage means between said outer wall member and said inner wall member, said inner wall member defining a measuring chamber therewithin; liquid communication means between said liquid passage means and said measuring chamber; and liquid transfer means in communication with said reservoir container and said liquid passage means, whereby liquid may be transferred into said measuring chamber from said reservoir container, through said liquid transfer means, said liquid passage and said liquid communication means.
Claim 2
Dependent Claim
129 words
Apparatus for measuring and dispensing liquid comprising a reservoir container having a flexible wall; measuring and dispensing means disposed on said reservoir container, said measuring and dispensing means comprising an outer wall member and an inner wall member, said inner wall member being disposed within said outer wall member and spaced therefrom to define liquid passage means between said outer wall member and said inner wall member, said inner wall member defining a measuring chamber therewithin; liquid communication means between said liquid passage means and said measuring chamber; and liquid transfer means in communication with said reservoir container and said liquid passage means, whereby liquid may be transferred into said measuring chamber from said reservoir container, through said liquid transfer means, said liquid passage and said liquid communication means.
Claim 3
Dependent Claim
72 words
Apparatus for measuring and dispensing liquid as defined in claim 1 wherein said inner wall member defining said measuring chamber is cup shaped, said cup shaped inner wall member spaced from said outer wall member, and seal means disposed around the upper circumference of said wall members, and wherein said means providing communication between said liquid passage means and said measuring chamber comprises at least one opening through said inner wall chamber.
Claim 4
Dependent Claim
90 words
Apparatus for measuring and dispensing liquid as defined in claim 1, wherein said reservoir container and said outer wall member are integral, said outer wall member and said reservoir container defining a throat where said outer member integrally joins said reservoir container, and plug means disposed in said throat, said plug means having a bore therein adapted to receive one end of said liquid transfer means, whereby liquid may be transferred from said reservoir container through said liquid transfer means and said plug means and into said liquid passage means.
Claim 5
Dependent Claim
82 words
Apparatus for measuring and dispensing liquid as defined in claim 1, wherein said reservoir container includes a neck portion having threads thereon said outer wall member having threads thereon adapted to engage said threads on said neck portion, said outer wall member also having a boss disposed thereon, said boss having a bore therein adapted to receive one end of said liquid transfer means, whereby liquid may be transferred from said reservoir through said conduit means and into said liquid passage means.
Claim 6
Dependent Claim
77 words
Apparatus for measuring and dispensing liquid as defined in claim 3, wherein said inner wall member defining said measuring chamber is cup shaped, seal means around the upper circumference of said cup shaped inner wall member, said seal means providing communication between said liquid passage means and said measuring chamber comprising at least one opening through said inner wall member and wherein the bottom of said cup shaped inner wall member is spaced from said plug means.
Claim 7
Dependent Claim
42 words
Apparatus for measuring and dispensing liquid as defined in claim 4, additionally comprising: closure engaging means disposed around the upper circumference of said outer wall member; and closure means including means adapted to secure said closure means to said outer wall means.

Apparatus for measuring and dispensing liquid as defined in claim 6, wherein said closure means has a portion thereof connected to said outer wall means.
Claim 9
Dependent Claim
25 words
Apparatus for measuring and dispensing liquid as defined in claim 2 wherein said seal means comprises a collar integrally defined on said inner wall member.
Claim 10
Dependent Claim
26 words
Apparatus for measuring and dispensing liquid as defined in claim 2 additionally comprising spacing means to space said inner and outer wall members from one another.
Claim 11
Dependent Claim
69 words
Apparatus for measuring and dispensing liquid as defined in claim 1 wherein said inner wall member defines an integral depending plug means received in a throat defined by said reservoir container, said plug means having a bore for receiving one end of said liquid transfer means, and said plug means defining a portion of said liquid passage means to provide communication between said reservoir and said liquid passage means.
