Abstract

Abstract An insulated container having a pump for generating air pressure over the liquid in the container so as to selectively dispense it. A valve arrangement is incorporated that prevents inadvertent displacement of the liquid from the container if the pump is accidentally actuated. The valve arrangement prevents discharge of liquid from the discharge spout and also prevents the transmission of air pressure from the pump to the area in the container over the liquid.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 122 words
In a dispensing container having a body portion defining a cavity for containing a liquid, pump means carried on the top of said body portion, said pump means having an outlet port in communication with said cavity for generating a pressure upon the liquid therein upon operation of said pump means, dispensing means extending laterally of the body portion and fixed relative thereto for delivering liquid from said cavity upon actuation of said pump means, the improvement comprising valve means movable between an opened position and a closed position, said valve means being effective to simultaneously close communication of said outlet port with said cavity and prevent liquid passage through said dispensing means when said valve means is in its closed position.
Claim 2
Dependent Claim 122 words
In a dispensing container having a body portion defining a cavity for containing a liquid, pump means carried on the top of said body portion, said pump means having an outlet port in communication with said cavity for generating a pressure upon the liquid therein upon operation of said pump means, dispensing means extending laterally of the body portion and fixed relative thereto for delivering liquid from said cavity upon actuation of said pump means, the improvement comprising valve means movable between an opened position and a closed position, said valve means being effective to simultaneously close communication of said outlet port with said cavity and prevent liquid passage through said dispensing means when said valve means is in its closed position.
Claim 3
Dependent Claim 56 words
A container as set forth in claim 1 wherein the valve means comprises a first valve for closing the communication of the outlet port with the cavity and a second valve for precluding flow through the dispensing means, said first and said second valves being connected to a common actuator for simultaneous opening and closing thereof.
Claim 4
Dependent Claim 24 words
A container as set forth in claim 1 wherein the valve means is supported for reciprocating movement between its open and its closed positions.
Claim 5
Dependent Claim 107 words
A container as set forth in claim 1 wherein the means for preventing the liquid passing through the dispensing means comprises a seal carried by a portion of the valve means slidably supported around a horizontally extending portion of the dispensing means, said seal being engageable with the open end of said horizontally extending portion when said valve means is in its closed position and spaced therefrom when said valve means is in its opened position, said portion of said valve means defining a downwardly opening cavity through which liquid is dispensed when said valve means is in its opened position and the pump means is actuated.
Claim 6
Dependent Claim 100 words
A container as set forth in claim 1 wherein the outlet port is positioned in a lower surface of the pump means, there being a second opening disposed beneath and aligned with said outlet port, said valve means having an apertured part slidably positioned between said outlet port and said second opening, the aperture in said apertured part being aligned with said outlet port and said second opening when said valve means is in its opened position and non-aligned therein when said valve means is in its closed position for preventing communication between said outlet port and said second opening.
Claim 7
Dependent Claim 107 words
A container as set forth in claim 5 wherein the means for preventing the liquid passing through the dispensing means comprises a seal carried by a portion of the valve means slidably supported around a horizontally extending portion of the dispensing means, said seal being engageable with the open end of said horizontally extending portion when said valve means is in its closed position and spaced therefrom when said valve means is in its opened position, said portion of said valve means defining a downwardly opening cavity through which liquid is dispensed when said valve means is in its opened position and the pump means is actuated.
Claim 8
Dependent Claim 231 words
A dispensing container having a body portion defining a cavity for containing a liquid, pump means carried by said body portion, said pump means having an outlet port in communication with said cavity for generating a pressure upon the liquid therein upon operation of said pump means, dispensing means for delivering liquid from said cavity upon actuation of said pump means, said dispensing means terminating in a discharge tube extending through a side of said body portion and outwardly therefrom for delivery of the liquid from said cavity, a first valve element slidably supported on said body portion and extending around at least a part of said discharge tube, said first valve element being slidable between an opened position and a closed position, said first valve element carrying sealing means in facing relationship to the end of said discharge tube and adapted to engage and close the end of said discharge tube when said valve element is in the closed position, and a second valve element, said second valve element being moveable between an opened position in which said outlet port is in communication with said cavity and a closed position in which said outlet port is out of communication with said cavity, the first valve element and said second valve element being connected to a common actuator for simultaneous movement of said valve elements to their opened and closed positions.
Claim 9
Dependent Claim 231 words
A dispensing container having a body portion defining a cavity for containing a liquid, pump means carried by said body portion, said pump means having an outlet port in communication with said cavity for generating a pressure upon the liquid therein upon operation of said pump means, dispensing means for delivering liquid from said cavity upon actuation of said pump means, said dispensing means terminating in a discharge tube extending through a side of said body portion and outwardly therefrom for delivery of the liquid from said cavity, a first valve element slidably supported on said body portion and extending around at least a part of said discharge tube, said first valve element being slidable between an opened position and a closed position, said first valve element carrying sealing means in facing relationship to the end of said discharge tube and adapted to engage and close the end of said discharge tube when said valve element is in the closed position, and a second valve element, said second valve element being moveable between an opened position in which said outlet port is in communication with said cavity and a closed position in which said outlet port is out of communication with said cavity, the first valve element and said second valve element being connected to a common actuator for simultaneous movement of said valve elements to their opened and closed positions.
Claim 10
Dependent Claim 52 words
A container as set forth in claim 7 wherein the second valve element comprises an apertured piece interposed between the outlet port and a part having an opening therein in communication with the cavity, seal means surrounding said outlet port and said opening for sealingly engaging opposite sides of said aperture piece.
Claim 11
Dependent Claim 52 words
A container as set forth in claim 7 or 8 wherein the discharge tube extends horizontally outwardly, the first valve element defining a downwardly extending opening adjacent said sealing means and through which liquid is discharged when said first valve element is in its opened position and said pump means is actuated.
