BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a container-dispenser of single lengths of paper dispensed by manual tearing from a continuous paper web wound up to form a roll, suitable to include two rolls at a time, one of which is in reserve.
Paper dispensers are known, in particular of toilet paper but also for the use as towels, which are wall-mounted in public places such as the rest rooms of motorway snack-bars, railway stations, airports, restaurants, etc., where the paper consumption is very high and the rolls are so frequently replaced that a very careful control is required whenever the paper rolls in reserve are not to be left directly available to the users for the replacement, with the consequence of unavoidable waste of material. In order to reduce the interventions of the personnel charged with the replacement, sometimes dispensers of toilet paper or towels have been adopted which are suitable to contain a pair of paper rolls, one of which in reserve, in such a way that a better store is available between one replacement and another. Usually in these known devices the two rolls are in turn accessible from the outside and it is the same user that displaces a slidable shutter, when a roll is finished, to make it possible to have access to the other. Of course there is no hindrance, however, that the user may take paper, no matter whether from one of the other roll by simply moving the shutter, until a possible suitable situation takes place in which both the rolls are partially exhausted and the person who has to carry out the replacement must choose between leaving the things as they are, with the risk that before a subsequent intervention all the paper is taken away from both the rolls, or carrying out an early replacement with unavoidable waste of material.
SUMMARY OF THE INVENTION
In order to avoid doubtful situations of this type, in which both the solutions would be disadvantageous, it has now been conceived, being the object of the present invention, a device for dispensing paper lengths from a roll, which is adapted to contain two paper rolls at a time, wherein the withdrawal is automatically ensured from the same preferential side. Thereafter the other side becomes accessible and the withdrawal can then be performed from the second roll in reserve, preferably until a fresh roll is inserted in the preferential exhausted side.
This main object of the present invention is obtained by means of a container-dispensing device for lengths of paper from a roll, having an external housing formed of a stationery portion and a cover, two pins substantially parallel, as support for unwinding from two rolls with two openings for the passage of paper in the lower part of the housing in correspondence with the pins, and having freely rotatable about one of the pins a sector of a circle member having a peripheral flange shaped as an arc of circle and adapted to obstruct the corresponding opening on the same side, as long as the sector is kept in a first substantially vertical position against the bias exerted by spring means tending to bring the sector to a second rotated position of rest, in correspondence of which the opening on the same side is freely accessible, there being provided means adapted to keep the sector in its substantially vertical position until thumb follower, fixed to the means and constantly in contact with the outer surface of a roll unwinding about the pin, come substantially in contact with the core of the roll itself, thus causing the sector to trigger to the second rest position under the bias of the spring means.
According to other particular aspects of the present invention, the inside of the device is inaccessible by the user during its normal operation and the relevant cover is fixed to the rear wall of the device itself by means of a central stiffening member having also the function of ashtray.
