Abstract
Abstract A combined cover and compactor assembly capable of being mounted on a container for trash or other compactible material has a housing having at least one side wall defining a transfer and compacting chamber therein. The housing has a side opening located in the side wall serving as an inlet to permit the compactible material to be charged into the transfer and compacting chamber, and a lower end opening in registry with the transfer and compacting chamber. The housing is connectible to the container by a housing support that is adjacent and defines the lower end opening to allow compactible material charged into the transfer and compacting chamber through the side opening to either fall or be forced into the container. A retainer assembly including an upper end opening is disposed at the upper end of the housing to releasably support a compactor within the transfer and compacting chamber. The compactor may act as a cover when it is held by the retaining assembly, or may be disengaged from the retaining assembly to move downward to exert compacting force upon the compactible material present in the transfer and compacting chamber.

Claim 1
Independent Claim
150 words
A combined cover and compactor assembly for mounting on a container having an open end and used for holding compactible material comprising: a. a housing having a side wall defining a transfer and compacting chamber, b. said side wall having a side opening communicating with said transfer and compacting chamber for charging compactible material thereinto, c. said housing having a lower end opening in communication with said transfer and compacting chamber for discharging compactible material therefrom, d. said housing having a housing support about the lower end for connecting the combined cover and compactor assembly to the open end of said container, e. retaining means located at the end of said housing remote from the lower end opening, and f. a compactor detachably connectible in said retaining means and to be disengaged therefrom for downward movement to exert compacting forces upon collected compactible material in said transfer and compacting chamber.
Claim 2
Dependent Claim
150 words
A combined cover and compactor assembly for mounting on a container having an open end and used for holding compactible material comprising: a. a housing having a side wall defining a transfer and compacting chamber, b. said side wall having a side opening communicating with said transfer and compacting chamber for charging compactible material thereinto, c. said housing having a lower end opening in communication with said transfer and compacting chamber for discharging compactible material therefrom, d. said housing having a housing support about the lower end for connecting the combined cover and compactor assembly to the open end of said container, e. retaining means located at the end of said housing remote from the lower end opening, and f. a compactor detachably connectible in said retaining means and to be disengaged therefrom for downward movement to exert compacting forces upon collected compactible material in said transfer and compacting chamber.
Claim 3
Dependent Claim
60 words
In the combined cover and compactor assembly as claimed in claim 1 wherein: a. said side wall is generally cylindrically shaped and defines a circular perimeter in the horizontal plane, b. said compactor is essentially disc-like and has a generally circular perimeter, and c. the diameter of said compactor is smaller than the diameter of said transfer and compacting chamber.
Claim 4
Dependent Claim
90 words
