Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
192 words
In a container for holding an additive which is to be progressively dissolved in flushing water when said container is immersed in a tank in which the flushing water is held, said container having a removable cover defining an outlet orifice therein, a water inlet orifice between said container's top and bottom, means for positioning said container in said tank with said inlet between the maximum and minimum levels of the water in said tank, and a supply of additive in said container beneath said inlet, the improvement which comprises a deflector positioned within said container in alignment with and opposite said inlet, with said deflector's lower edge above the upper surface of said additive, said deflector degining, between it and the wall of said container in which said inlet is formed, a vertical passage extending from a first open end above said inlet to a second open end below said inlet, through which passage water entering through said inlet is deflected by said deflector against said upper surface of said additive, said passage having a cross-sectional dimensions parallel to said wall which is substantially greater than the width of said inlet.

Dependent Claim

Claim 3
Dependent Claim
12 words
Container as claimed in claim 1 which is generally prismatic in shape.
Claim 4
Dependent Claim
28 words
Container as claimed in claim 2 which has the shape of a prism having a rectangular base with said additive filling said container to about half its height.
Claim 5
Dependent Claim
23 words
Container as claimed in claim 1 in which the outlet orifice is formed in a separable cover at the top of the container.
Claim 6
Dependent Claim
31 words
Container as claimed in claim 1 in which the deflector defines a general vertically passage parallel to the major axis of the container between said deflector and on adjacent container wall.
Claim 7
Dependent Claim
35 words
Container as claimed in claim 5 in which the deflector has a transverse section of arcuate shape with the ends of the arc bearing against the wall of the container which defines the inlet orifice.
Claim 8
Dependent Claim
44 words
Container as claimed in claim 5 in which the maximum width of the generally vertical passage defined between the deflector and said wall, measured in the direction of the thickness of the container, lies between 0.2 and 0.5 times the thickness of the container.
Claim 9
Dependent Claim
43 words
Container as claimed in claim 1 in which the deflector is urged against the wall of the container which carries the inlet orifice by a projection bearing against the opposite wall of the container and centered in a hole in said opposite wall.
Claim 10
Dependent Claim
31 words
Container as claimed in claim 1 in which the height to which the additive initially fills the container lies between 30 and 60 percent of the total height of the container.
Claim 11
Dependent Claim
36 words
Container as claimed in claim 1 in which the ratio between the cross-sectional area of the container and the total lateral surface of the container lies between 1 and 20 and preferably between 2 and 10.
Claim 12
Dependent Claim
89 words
Container as claimed in claim 1 in which the inlet orifice is a substantially circular orifice the diameter of which lies between 0.02 and 0.10 times the height of the container, the center of said orifice being located at a distance between 0.07 and 0.35 times the height of the container above the maximum level of additive in said container, the lower edge of the deflector being positioned at a distance between 0.05 and 0.25 times the height of the container away from the center of the inlet orifice.
