DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device for wrapping household refuse and waste and waste resulting from medical care administered to humans and animals as well as the waste produced by the activities connected with this care.
At the present time, the wrapping of waste is taken care of by using plastic bags or plastic-coated boxes. This type of wrapping does not enable the gases or odours issuing from the waste, to be correctly confined.
This results in a volatile propagation of pathogenic germs and unpleasant smells, which presents a problem of potential contamination, particularly in health care facilities, maternity hospitals, veterinary clinics, medical laboratories, public toilets through women's sanitary towels, and more simply waste disposal units of apartment blocks.
The device according to the invention overcomes this shortcoming by wrapping the waste in envelopes which are air-, odour- and liquid-tight whatever the position of said envelopes after closure.
The device can in particular be fixed on waste disposal unit openings in apartment blocks, therefore guaranteeing constant cleanliness of the ducts and performing the role of anti-odour trap when being used.
Similar systems have already been studied, for example the one described in European Patent No. 281 355, but the latter obliges the user to push the objects in order to obtain advance of the sleeve; there is no driving system and the bags obtained are simply closed by twisting, which does not allow a real tightness.
In European Patent No. 05660, the system described does not enable the dimensions of the wrapping to be automatically adjusted and a system of pliers rather than rollers is used to advance the sleeve.
The dimensions of the wrapping can be modified by replacing an element of the mechanism, but giving another standardized dimension. The mechanism described is not functional for the systematic wrapping of each unitary deposit with systematic adaptation of the dimension of sleeve necessary;
The main innovation of the present invention is the systematic adaptation of the dimension of the wrapping to the waste.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a side cut-away view of the apparatus.
FIG. 2 is a diagonal view of the feed rollers and heat seal assembly.
FIG. 3 is a cross-section view of the feed roller drive mechanism.
Referring to FIG. 1, the device is constituted by a housing (1) acting as frame supporting in its upper part a dispenser (2) of heat-sealable plastic sleeve (3) forming receptacle for depositing the waste, a mechanism (4) for driving said sleeve just underneath, followed by a heat-sealing mechanism (5) then a removable receptacle (6) allowing the installation of a secondary wrapping with a view to periodic emptying.
The waste dropped into the primary receptacle drops to the bottom thereof to be driven by said sleeve (3), itself driven by friction between at least two rollers or wheels rotating in opposite directions with respect to each other, being disposed on the one hand so as to obtain a permanent contact pressure with the sleeve, disposed on the other hand so that the contact surfaces of said rollers move apart upon passage of the waste while conserving a contact pressure with the sleeve, the quantity of sleeve necessary for wrapping the waste and regenerating the soiled surfaces being connected with the number of rotations of said rollers, said number of rotations being adjustable as desired by the user or automatically by a detection system, the advance of the sleeve thus obtained driving the imprisoned waste beneath the rollers, tight closure being effected as desired or automatically by actuating heat-sealing pliers capable of cutting the sleeve in the middle of a wide weld effecting at the same time tightness of the envelope created and the bottom of the following envelope.
A mechanism for automatically or manually dispensing a neutralizing product of germicidal or like type, may be installed above the dispenser forming receptacle. Its operation may be determined by mechanical or electrical link b
