DETAILED DESCRIPTION OF THE INVENTION

In FIGS. 1 to 7 is shown a dispensing box (1) according to the invention, designed to receive a wiping material (M) which can be unwound in a strip (S). The wiping material (M) is pre-cut, that is to say the strip (S) includes pre-cut lines. These lines constitute localised weakening areas, making it easier to cut the strip (S) into separate sheets.

The box (1) comprises a body (10), a cover (20), and a roll (30) for guiding the strip (S). With its reduced number of parts, the box (1) is simple, practical, economic and ecological.

The body (10) consists of five fixed walls (11, 12, 13, 14, 15) delimiting an interior space (16) for receiving the wiping material (M), in the shape of a spool (B) or a block. The body (10) includes a front wall (11), a rear wall (12), two side walls (13, 14) and a bottom wall (15). Advantageously, some or all of the fixed walls (11-15) can be constituted by a flat plate, so as to simplify the construction of the body (10) and reduce its manufacturing cost. Preferably, the body (10) is made of plastic material. The rear wall (12) can be provided with a system for attachment to a vertical support, such as a wall or a piece of furniture. The side walls (13, 14) can be shaped to serve as feet for the body (10), to place the box (1) on a horizontal support, when the box (1) is not attached to the vertical support, or when the rear wall (12) has no attachment system. The material (M) is which can be unwound in a strip (S) on a front side (17) of the body (10), between the cover (20) and the roll (30), above the front wall (11).

The cover (20) consists of a slightly domed plate in the central part (21). The cover (20) is hinged on a rear side (18) of the body (10), on the side walls (13, 14), above the rear wall (15). Preferably, the cover (20) is made of plastic material. Alternatively, the cover (20) can be made of metal or incorporate a metal portion, to adjust the pressure exerted on the strip (S) and the roll (30).

The roll (30) is pivotally mounted on the body (10) on the front side (17). The roll (30) guides the strip (S) from the spool (B) to the outside of the box (1) and the user. The roll (30) is a part of revolution. Preferably, the roll (30) is made of plastic material, with an outer surface made of elastomeric material provided to receive the strip (S).

The roll (30) comprises a central part (31) and two ends (32) mounted in pivoting connection on the side walls (13, 14) of the body (10). The central portion (31) comprises a cylindrical portion (33) and an elastomeric ring (37). On each side of the central part (31), the roll (30) comprises a conical portion (34) with a diameter decreasing towards the end (32), a conical portion (35) with a diameter increasing towards the end (32), and a side stud (36). For example, the conical portion (34) has a slope of 8°, while the conical portion (35) has a slope of 7°, relative to the central axis.

One of the studs (36) is housed in the wall (14), while the other stud (36) is housed in a button (30B) mounted on the wall (13). The button 30B is a safety button with non-return freewheel. The button 30B prevents the strip (S) from being withdrawn inwards and, by rotating, allows the strip (S) to stick out, in case there is little sticking out. This prevents the device from breaking down.

The ring (37) defines a central section (38) of maximum diameter (D1). Between the conical portions (34, 35), the roll (30) includes two side sections (39) of locally minimum diameter (D2). The diameter (D1) is greater than the diameter (D2). For example, the diameter (D1) is equal to 50 mm, while the diameter (D2) is equal to 20 mm. Preferably, the diameter (D1) is greater than or equal to twice the diameter (D2).

The box (1) is designed to cut the strip (S) pulled manually by a user. The sections (38, 39) are provided to bearingly receive the strip (S) surmounted by the cover (20). The roll (30) has three contacts on the strip (S), at the three sections (38, 39).

When a user pulls the strip (S) on the front side (17) of the body (10), the strip (S) rotates the roll (30) about its central axis. In reaction, the sections (38, 39) of different diameters (D1, D2) drive the strip (S) with a speed differential (V1, V2) therebetween. The upper section (38) of diameter (D1) drives the strip (S) with maximum speed (V1), while the sections (39) of lower diameter (D2) drive the strip (S) with a minimum speed (V2).

The invention thus allows to tear the strip (S) at a pre-cut line, starting at the central part (31). The speed differential (V1, V2) separates the formats by stretching. Another advantage is the exit dimension of the strip (S) for the grip.

Preferably, the cover (20) has a lower profile matching the outer profile of the roll (30), to press the strip (S) onto the roll (30) at each of the sections (38, 39) of different diameters (D1, D2). The weight and shape of the cover (20) can be adapted to adjust the pressure exerted on the strip (20) and the roll (30).

Moreover, the box (1) can be shaped differently from FIGS. 1 to 7 without departing from the scope of the invention, which is defined by the claims.

According to a variant not shown, the roll (30) can have only two contacts. For example, the roll (30) includes a section (38) of diameter (D1) disposed on a first side, and a section of diameter (D2) smaller than the diameter (D1) disposed on a second side. The roll (30) may include a frustoconical portion (34) between the two sections (38, 39). The sections (38, 39) of different diameters (D1, D2) drive the strip (S) with a speed differential (V1, V2) therebetween, so as to tear the strip (S) at a pre-cut line, starting at the section (38) of larger diameter.

Furthermore, the technical features of the various embodiments and variants mentioned above may be, in whole or for some of them, combined with each other. Thus, the box (1) can be adapted in terms of cost, functionality and performance.
