Abstract
Abstract A dispenser for liquids and solids or the like includes a container body with inter-connected top and bottom walls to form the container with a break-open aperture formed in the top wall and a hollow spout located within the dispenser beneath the aperture so that it can be pulled therethrough after the aperture is opened to form a spout for the dispenser. When the aperture is opened the spout is usually lifted or pulled out of the container body with the portion of the aperture broken free from the top wall and the spout is tapered so the periphery of the aperture will wipe the exterior of the spout clean of and liquids or solids as it is pulled from the container to form a pourable spout through which the contents within the container body may be dispensed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
217 words
A fluid tight dispenser for materials which has a pop-open feature with a self-contained spout comprising: a container having a hollow body portion closed at its opposite ends respectively by a plate-like top wall and a bottom wall; a break-away portion formed in said top wall; pull means attached to said break-away portion on its outer surface operable when manually manipulated to force a partial separation between said break-away portion and said top wall thereby forming an aperture in said top wall when the breakaway portion is removed; and tubular hollow rigid spout means located within said hollow body portion, said spout means having a smooth outer wall and also having one end thereof attached to the inside surface of said break-away portion so said spout means can be extracted through the aperture formed as said break-away portion is separated from said top wall, said spout means sized to said aperture so its smooth outer wall continuously engages and expands the periphery of the aperture in a sealing relationship along a substantial portion of the length of said spout means as said spout means is extracted whereby an exterior service spout is formed as said spout is extracted through which materials within the dispenser can be poured therefrom without leakage between the spout means and the aperture.
Claim 2
Dependent Claim
217 words
A fluid tight dispenser for materials which has a pop-open feature with a self-contained spout comprising: a container having a hollow body portion closed at its opposite ends respectively by a plate-like top wall and a bottom wall; a break-away portion formed in said top wall; pull means attached to said break-away portion on its outer surface operable when manually manipulated to force a partial separation between said break-away portion and said top wall thereby forming an aperture in said top wall when the breakaway portion is removed; and tubular hollow rigid spout means located within said hollow body portion, said spout means having a smooth outer wall and also having one end thereof attached to the inside surface of said break-away portion so said spout means can be extracted through the aperture formed as said break-away portion is separated from said top wall, said spout means sized to said aperture so its smooth outer wall continuously engages and expands the periphery of the aperture in a sealing relationship along a substantial portion of the length of said spout means as said spout means is extracted whereby an exterior service spout is formed as said spout is extracted through which materials within the dispenser can be poured therefrom without leakage between the spout means and the aperture.
Claim 3
Dependent Claim
30 words
The dispenser defined in claim 1 wherein the spout means includes an integral air vent allowing atmospheric gases to enter the container as fluid egresses therefrom through said spout means.
Claim 4
Dependent Claim
42 words
The dispenser defined in claim 1 wherein the break-away portion is connected to the spout means with a tab extending from the latter whereby said break-away portion can be swung clear of the outer opening of said spout means after its extraction.
Claim 5
Dependent Claim
39 words
The dispenser defined in claim 1 wherein the spout means has a stop located on its end remote from the break-away portion that limits its extension when said stop engages said top wall when said spout means is extracted.
Claim 6
Dependent Claim
54 words
The dispenser defined in claim 1 wherein the pull means includes a ring member whereby it may be manually raised and utilized to extract the spout means from the dispenser when the break-away portion of the top wall has separated therefrom said ring member being connected to said spout means through said break-away portion.
Claim 7
Dependent Claim
31 words
The dispenser defined in claim 5 wherein the pull means includes levEr means to assist in separating the break-away portion from the top wall as the pull means is manually lifted.
Claim 8
Dependent Claim
32 words
The dispenser defined in claim 1 wherein the container includes an air vent means which can be opened to prevent a vacuum from occurring within the dispenser when the dispenser contains liquids.
Claim 9
Dependent Claim
31 words
The dispenser in claim 7 wherein the vent means includes a rubber grommet located in an aperture in the container which grommet can be removed to provide the air vent means.
Claim 10
Dependent Claim
70 words
The dispenser as defined in claim 1 wherein a generally circular groove defines the break-away portion in the top wall of the dispenser which weakens the connection therebetween and wherein the tubular hollow spout is generally cylindrical, said tubular spout sized so its smooth outer wall continuously expands the area of the aperture as it is extracted along a substantial portion of its length, thereby forming a continuous seal therebetween.
Claim 11
Dependent Claim
86 words
The dispenser as defined in claim 9 wherein the elongated spout means tapers to larger diameter from the end connected to the break-away portion to the end remote from the top wall so its cross sectional area continuously increases along its length, with said end of said spout means connected to the break-away portion having a cross sectional area substantially equal to the cross sectional area of the aperture so a substantial portion of said spout means has a greater cross sectional area than said aperture.
Claim 12
Dependent Claim
19 words
The dispenser defined in claim 9 wherein the break-away portion is located adjacent to one edge of the container.
Claim 13
Dependent Claim
22 words
The dispenser defined in claim 9 wherein the spout means is curved and has a length approximating the height of the container.
Claim 14
Dependent Claim
18 words
The dispenser defined in claim 9 wherein the top wall thereof is formed of a light gauge metal.
Claim 15
Dependent Claim
13 words
The dispenser as defined in claim 13 wherein the light-gauge metal is aluminum.
