DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention concerns a device for closing and ejecting a disposable bag of a vacuum cleaner, the bag being fixed, during a cleaning operation on a part of the housing of said vacuum cleaner.
The invention is applied in a general manner to any mobile vacuuming unit of the vacuum cleaner type, which is displaceable by the user in a zone to be cleaned and comprises a bag for trapping dust, being removable and disposable.
PRIOR ART
In a general manner, vacuum cleaner bags have an opening which it is suitable to close when said bag is filled with dust, in order to maintain the latter in the bag. It is thus already known to have recourse to closing systems comprising a tongue made of cardboard for example and folded upon itself at least in part. The user can then unfold this tongue by pulling on this latter which has for its consequence to close the opening of the bag. Such devices present a certain number of inconveniences. In effect, the user is obliged to have direct access to the bag in order to be able to pull on the tongue. It appears in addition indispensable to utilize parts having relatively large dimensions to assure a correct closing of the bag. Such an operation is moreover irreversible, and no longer permits the user to open the bag once it has been closed.
It is equally known to provide blocking means for bags, for example by the intermediary of French Document A-932,776, which describes a bag furnished with a closing means. This latter pivots between an opening position and a closing position of the filling opening of the bag, with the aid of a mechanical system constituted by a pivot axis, an elastic restoring means as well as a part serving as an abutment for the closing means, arranged on a rigid plate of the bag. Such a system presents a group of inconveniences and notably, in its construction, for which a number of distinct and substantial pieces are necessary, thus generating a high fabrication cost.
In addition, the arrangement of the system and more particularly of the closing means on the rigid plate, in an accessible manner, weakens said system, and the particular configuration of the closing means does not permit simple and/or automatic operation thereof with an independent control member.
The object of the present invention is to remedy the inconveniences of the prior art and to provide a vacuum cleaner bag furnished with a closing flap for its filling inlet, which is easily manufactured, solid, and inexpensive.
The object of the present invention consists in furnishing a closing device for the vacuum cleaner bag which the user can manipulate without entering into direct contact with said bag during the closing operation.
Another object of the invention consists in utilizing a means for closing the vacuum cleaner bag which occupies a limited space, is easily fabricated, is inexpensive and can be disposed in an opening or closing position at the will of the user.
Another object of the invention is to furnish a safety device intended to prevent fixation of the suction pipe on the housing of the vacuum cleaner when the bag is closed.
A supplementary object of the invention is to furnish an automatic closing device for vacuum cleaner bags.
SUMMARY OF THE INVENTION
The objects of the present invention are achieved with the aid of a closing device for a disposable vacuum cleaner bag, said bag comprising a rigid zone in the vicinity of a closable filling inlet, in order to fix said bag on a part of the housing of the vacuum cleaner, as well as a closing flap of said bag, displaceable by rotation between an opening position and a closing position of the filling inlet in the plane of extension of the rigid zone, characterized in that the closing flap is mounted in the rigid zone, which is provided with a shaped perforation whose form and contour constitute a guiding means in which the closing flap is displaced.
The objects of the invention are equally achieved with the aid of a disposable sack for a vacuum cleaner comprising a rigid zone in the vicinity of its c
