DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a stack of sanitary papers, their dispenser and the method for manufacturing the stack.
Stacks of interleaved sheets of sanitary paper offer a number of advantages over paper on a roll. Dispensing sheet by sheet is more economical than a roll with precut surfaces which rotates by itself and, hence, is susceptible to being turned and several sheets being taken off. Again, at constant volume, the product density in a stack of sheets is higher than for a roll because of the lack of a spindle.
In view of such economy and compactness, sanitary paper in sheet form is ideally suited, especially where many people are present.
The sheet products of the prior art offer the advantage of improved sanitation as compared to rolls, because in shipping each stack is protected whereas a roll is not. However, these sheet stacks of the prior art entail the drawback as regarding groups of people in that the sheet stacks require handling to be put into dispensers. Such handling causes waste. Further, when coming to the end of use of a loaded dispenser, the last sheets tend to drop out, causing additional waste.
Accordingly, a first object of the invention is to provide a stack of sanitary sheets folded so as to be interleaving, making it possible to avoid waste and assuring easy implementation, in particular where a large group of people are involved.
This problem is solved by a stack of sanitary paper consisting of sheets so folded as to be interleaving and forming a pile inside a cardboard sleeve which is open at both ends, and being characterized in that the sleeve comprises a first pair of opposite sides which are parallel and adjacent to the sheet folds, a second pair of sides which are parallel to the sheet surfaces and perpendicular to the first pair, and an opening in at least one of the sides of the second pair.
In an additional feature, the stack comprises a second opening in the second side of the second pair.
In another feature, the openings are oval.
In another feature, the openings are circular.
Another object of the invention is a dispenser for the above stacks.
Regarding that object of the invention, the stack dispenser comprises a right-parallelepiped envelope of which the height corresponds to N superposed stacks and the base of which corresponds to the area of a folded sheet, and two narrow side supports adjacent to vertical, opposite sides of the envelope so as to subtend an opening larger than that of the sleeves.
In another feature of the invention, the dispenser includes a transparent door on that side opposite the envelope fastening side to make visible the filling level of the sleeve.
In another embodiment, the dispenser comprises a hollow envelope shaped to receive a stack of papers on either side of a plane of symmetry through which a pivot shaft passes, the sides opposite to the plane through which passes the pivot shaft about a fixed part of the dispenser being equipped with side supports defining a larger opening than that of the sleeve but less than the stack size; and further, aligned with the envelope of which the opening is not in the dispensing position, a seal for the opening solidly joined to the stationary dispenser part.
In an additional feature, one of the envelope sides, which is located in a plane parallel to the pivot shaft and is on the same side of this shaft, is provided with a transparent door.
Lastly, an object of the present invention is a method for manufacturing stacks of sanitary paper consisting of folded, interleaving sheets which allow for the economical use of these stacks.
This object is achieved in that the manufacturing method of stacks of sanitary sheets which are folded in an interleaving manner comprises the following stages:
cutting at least one row of apertures, at equidistant spaces, matching the width of a stack and in a direction parallel to a folding generatrix into a wide cardboard strip,
stacking strips of the wide, interleaving paper sheets,
folding along the generatrices and winding a cardboard strip around the stack of sheet
