Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
96 words
A waste material collecting bin, comprising: a storage container; an inlet to said storage container; a reservoir of a fluent material-treating substance; fluent addition means for adding said fluent substance from said reservoir to waste material added to said container; and an arcuate support means provided in said inlet for temporarily supporting waste material while it is contacted by said fluent substance from said reservoir, said fluent addition means being disposed above said arcuate support means such that said fluent substance is added to the waste material temporarily supported on said arcuate support means from above.
Claim 2
Dependent Claim
96 words
A waste material collecting bin, comprising: a storage container; an inlet to said storage container; a reservoir of a fluent material-treating substance; fluent addition means for adding said fluent substance from said reservoir to waste material added to said container; and an arcuate support means provided in said inlet for temporarily supporting waste material while it is contacted by said fluent substance from said reservoir, said fluent addition means being disposed above said arcuate support means such that said fluent substance is added to the waste material temporarily supported on said arcuate support means from above.
Claim 3
Dependent Claim
31 words
A collecting bin as claimed in claim 1, in which the support member is part of a valve closing the inlet and turnably mounted in an upper part of the bin.
Claim 4
Dependent Claim
15 words
A collecting bin as claimed in claim 2, in which the valve is pedal operated.
Claim 5
Dependent Claim
95 words
A collecting bin as claimed in claim 2 in which as the valve turns into its open position, it exposes an opening through which the waste material can pass and at the same time exposes a platform on which the waste material can temporarily lodge, whereby as the valve turns back into its closed position, spray means is actuated to add substance from the reservoir to the waste material before the platform is completely removed from below the waste material allowing the latter to drop suitably treated by the sprayed substance into the storage container.
Claim 6
Dependent Claim
54 words
A collecting bin as claimed in claim 2 in which the closed position of the valve is a position of minimum-stored energy, the opening of the valve being accompanied by a stressing of a spring which effects addition of the fluent material as it returns to its unstressed condition during closing of the valve.
Claim 7
Dependent Claim
36 words
A collecting bin as claimed in claim 1, in which the means to add fluent material-treating substance to the waste material includes a spray nozzle communicating with a pump containing fluent substance drawn from the reservoir.
Claim 8
Dependent Claim
33 words
A collecting bin as claimed in claim 6, in which expulsion of the fluent substance from the pump is effected by spring means which act to return the valve to the closed position.
Claim 9
Dependent Claim
84 words
A collecting bin as claimed in claim 1, in which a rotary valve is used to close the inlet, this valve being linked to a foot pedal and a liquid pump whereby depressing the foot pedal opens the rotary valve adjacent to the inlet, fills the pump with treating liquid and primes a spring, release of the foot pedal then allowing the spring to empty the pump of liquid, via spray nozzles adjacent to the inlet, as the valve returns to its closed position.
