Abstract
Abstract A water treatment container is disclosed having a first chamber of variable volume and an second chamber for containing a water treating agent such as an ion exchange resin. Retainers are situated on the inlet and outlet of the second chamber to retain the water treating agent within the second chamber. Filters are positioned adjacent to retainers to filter the water. The first chamber is constructed so as to have a manually variable volume. Water added to the first chamber is caused to flow through the second chamber and out a dispensing outlet as the volume of the first chamber is reduced by application of a manually applied pressure.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
136 words
A fluid treatment apparatus comprising a unitarily formed tubular body including a first fluid reservoir chamber, the first chamber having a sidewall in the form of a cylindrical resilient bellows for permitting the volume of the chamber to be varied by the application of an axial force, a second collinear chamber for containing a fluid treating agent and having an inlet and an outlet, the second chamber inlet being situated contiguously to the first chamber outlet, retaining means situated in the second chamber inlet and outlet for retaining the fluid-treating agent in the second chamber, and means sealing the first chamber for causing fluid to flow from the first chamber through the second chamber and out the second chamber outlet as the volume of the first chamber is reduced by the application of said axial force.
Claim 2
Dependent Claim
136 words
A fluid treatment apparatus comprising a unitarily formed tubular body including a first fluid reservoir chamber, the first chamber having a sidewall in the form of a cylindrical resilient bellows for permitting the volume of the chamber to be varied by the application of an axial force, a second collinear chamber for containing a fluid treating agent and having an inlet and an outlet, the second chamber inlet being situated contiguously to the first chamber outlet, retaining means situated in the second chamber inlet and outlet for retaining the fluid-treating agent in the second chamber, and means sealing the first chamber for causing fluid to flow from the first chamber through the second chamber and out the second chamber outlet as the volume of the first chamber is reduced by the application of said axial force.
Claim 3
Dependent Claim
13 words
The apparatus of claim 1 wherein the fluid-treating agent is an ion-exchange resin.
Claim 4
Dependent Claim
22 words
The apparatus of claim 1 wherein the fluid-treating agent is selected from the group consisting of Zeolite, activated charcoal, and calcium hypochlorite.
Claim 5
Dependent Claim
23 words
The apparatus of claim 1 wherein the retaining means comprises a filtering means for filtering the water entering and leaving the second chamber.
Claim 6
Dependent Claim
22 words
The apparatus of claim 1 wherein the first chamber further comprises an inlet and an inlet sealing means for sealing the inlet.
Claim 7
Dependent Claim
15 words
The apparatus of claim 1 further comprising means for selectively sealing the second chamber outlet.
Claim 8
Dependent Claim
128 words
A fluid treatment apparatus comprising a generally tubular unitarily formed hollow body including a first portion having an inlet through which the fluid to be treated can be introduced into the first portion and a second portion having an outlet, the inlet, first portion, second portion, and outlet being disposed in a serial, collinear relation, the second portion including a fluid-treating agent and retaining means for retaining the fluid-treating agent within the second portion, the first portion including means for permitting the volume of the first portion to diminish in response to manually applied axial pressure to cause treated fluid to be dispensed from the outlet of the second portion and filtering means adjacent to the retaining means for filtering the fluid as it passes through the apparatus.
Claim 9
Dependent Claim
128 words
A fluid treatment apparatus comprising a generally tubular unitarily formed hollow body including a first portion having an inlet through which the fluid to be treated can be introduced into the first portion and a second portion having an outlet, the inlet, first portion, second portion, and outlet being disposed in a serial, collinear relation, the second portion including a fluid-treating agent and retaining means for retaining the fluid-treating agent within the second portion, the first portion including means for permitting the volume of the first portion to diminish in response to manually applied axial pressure to cause treated fluid to be dispensed from the outlet of the second portion and filtering means adjacent to the retaining means for filtering the fluid as it passes through the apparatus.
Claim 10
Dependent Claim
21 words
The apparatus of claim 7 further comprising means removable from the first portion for permitting the introduction of untreated fluid therein.
Claim 11
Dependent Claim
25 words
The apparatus of claim 7 wherein the body consists essentially of a material sufficiently transparent to permit visual inspection of the fluid-treating agent situated therein.
Claim 12
Dependent Claim
18 words
The apparatus of claim 7 wherein the filtering means comprises a filter having about a 5 micron mesh.
Claim 13
Dependent Claim
128 words
A fluid treatment apparatus comprising: a first chamber having a volume variable by the application of an axial force, and an outlet, a second collinear chamber for containing a fluid-treating agent and having an inlet and an outlet, the second chamber inlet being situated contiguously to the first chamber outlet, retaining means situated in the second chamber inlet and outlet for retaining the fluid-treating agent in the second chamber, and means sealing the first chamber for causing fluid to be retained in the first chamber when no axial force is applied to the first chamber and to flow from the first chamber through the second chamber and out the second chamber outlet as the volume of the first chamber is reduced by the application of the axial force.
Claim 14
Dependent Claim
128 words
A fluid treatment apparatus comprising: a first chamber having a volume variable by the application of an axial force, and an outlet, a second collinear chamber for containing a fluid-treating agent and having an inlet and an outlet, the second chamber inlet being situated contiguously to the first chamber outlet, retaining means situated in the second chamber inlet and outlet for retaining the fluid-treating agent in the second chamber, and means sealing the first chamber for causing fluid to be retained in the first chamber when no axial force is applied to the first chamber and to flow from the first chamber through the second chamber and out the second chamber outlet as the volume of the first chamber is reduced by the application of the axial force.
