DETAILED DESCRIPTION

(16) To make the object of the invention more tangible, it is now described in a non-limiting way illustrated in the drawings.

(17) The pre-cut wiping material dispenser is designated with general reference (A). The wiping material (E) appears in a roll and may find applications as a hand wipe, toilet paper, household roll towels and, more generally, such a wiping material for sanitary purposes is intended to be used in public premises or for a private use by consumers or in organization, such as, for example, hospitals, clinics, or the like, or may be used in other industrial applications.

(18) The device thus comprises a housing (1) comprising a back wall (1a) two lateral walls (1b) and a wall for supporting (1c) the roll of material (E). The housing receives a hinged flap (2) ensuring the guiding and the unwinding of the roll of material. A cover (3) is hinged with respect to the housing by axes (3a) cooperating with openings (1d) formed on the lateral walls (1b) of the housing.

(19) According to the invention, the wall (1c) for supporting the roll of material has a horizontal portion (1c1) and, on either side, two front and back oblique portions (1c2) and (1c3) having a same inclination, thus enabling to receive and to center the roll of material. Front oblique portion (1c2) is jointed by its lower portion to the horizontal central portion (1c1) recessed with respect to the front end of the housing to define a volumetric space (V) with the flap (2) enabling the operator to engage and to position his fingers in order to grab the strip of material unwound from the roll. In other words, the roll of material (E) is properly centered and positioned on the horizontal support portion (1c1), thus enabling to control its position and avoiding any rocking. The oblique portions (1c2) (1c3) are inclined with respect to the horizontal portion (1c1) according to an angulation a approximately ranging from 30 to 60. The volumetric space (V) is thus particularly large with respect to the positioning of the flap (2), which is located at the front of the housing. This space has a substantially triangular configuration along the entire length of the device housing.

(20) The flap (2) has an upper profile (2a) of curved configuration with, at its end, two fingers (2b) capable of engaging into openings (1e) formed on the lateral walls of the housing. In the implementation illustrated in FIG. 1, the flap (2) has in its lower portion a central opening (2c) of substantially circular configuration with a very deep oblique slot (2d) on either side. They thus define, between the opening (2c) and the slots (2d), a tab (2e). The flap (2) may have a flat shape or may be provided with bulged areas as described in one of the previous patents of the Applicant.

(21) The cover (3) comprises a locking device known per se, not shown, to be fastened to the housing. The cover has on its wall (3b) opposite to the flap (2) a central opening (3c) of same configuration as opening (2c), and on either side of said opening (3c), protruding ribs (3d) which are capable of penetrating into the slots (2d). The ribs have a tear drop configuration, with a rounded shape (3d1) located close to the lower end of the lower portion of the cover. Portion (3b) of the cover is continued by a wall (3e) covering the housing, this wall being capable of having a curved profile or of having a configuration with different faces as shown in FIG. 1.

(22) In the variation of FIG. 6, the housing remains identical to that described previously. The flap (2) has the same configuration, except for the slots (2d), which are replaced with end tabs (2f) formed close to the edges of said flap with slots (2g) between the tabs (2f) and the flap wall, said slots (2g) contributing to provide resilience to the flap on pulling of the strip of material.

(23) The cover (3) in this specific configuration has, on either side of the central opening (3c), folded portions (3f) behaving as stops for the wiping material. Slots (3g) are formed between the portions (3f) forming stops and the lateral walls (3h) of the cover.

(24) FIG. 8 shows a variation of the device identified in FIGS. 6 and 7 with the fitting, in this case, of two compartments (c1) and (c2) separated by a transverse plate (1f). There thus are two compartments for receiving two rolls of wiping material, two flaps (2) independent from each other, and a single cover (3) for covering the entire housing on closing of the device. In this configuration, the cover has two openings (3c) which are intended to be located opposite to each opening (2c) formed on each of the flaps.

(25) FIGS. 10 and 11 show two specific flap shapes.

(26) The flap shown in FIG. 10 corresponds to that identified in FIG. 6. The flap shown in FIG. 11 comprises, on either side of its central opening (2c), two slots (2d) delimiting two tabs (2e) for allowing the passage of the ribs (3d) formed on the cover. At its end, the flap has tabs (2f) and slots (2g) such as described previously. Referring to FIGS. 12 to 15, the wiping material dispenser has been shown in a configuration with two compartments (c1) (c2) separated by a transverse plate (1f). It comprises the support portion (1c) such as defined previously. The transverse plate (1f) located inside of the housing volume extends substantially outwards beyond the front portion (1c2) by forming a protruding portion (1f1) with a front edge (1f2) forming a bearing stop. In this embodiment, the flap (2) comprises between central openings (2c) two parallel slots (2h) delimiting a tab (2m) between them, said tab being capable of bearing against the edge (1f2) of the transverse plate. The two slots (2h) contribute to providing resilience to each corresponding portion of the flap of each compartment (c1) or (c2).

(27) Further, and in an optimized embodiment of the invention, the cover (3) is fitted to receive a selector (4) sliding on the outside with respect to the cover (3) and arranged to horizontally move in order to close, now the opening (2c) of the flap in relation with compartment (c1) of the housing, now the opening (2c) in relation with compartment (c2) of the housing, and this, in an alternating back and forth motion along the direction indicated by arrow (f). For this purpose, the cover is provided with a very long horizontal recess (3m) allowing the alternating motion of said selector (4). The latter thus comprises a plate of vertical trapezoidal configuration (4a) with a beading (4b) in its upper portion, capable of displacing within the recess (3m). An upper stop part (5) enables to control the displacement of the selector by being maintained in vertical position. Either the stop part (5) is assembled and attached by means (5a) on the cover, or the cover and this part (5) are formed in one piece on manufacturing. The selector (4) further has in its lower portion an inner leg (4c) which continues the stop parts (3f) formed on the cover. The trapezoidal configuration of the selector enables to totally close, to the right or the left, one of the openings (2c) formed on the flap (2). It can thus be understood that the operator selects the roll of material to be unwound by a simple horizontal manipulation of the selector along the direction indicated by the arrow (F).

(28) The solution provided by the Applicant provides a dispensing device of very simple design with only three or four components, according to the presence or not of the selector (4), that is, the housing (1), the flap (2), the cover (3). In all embodiments, whatever the configuration of the flap, several variations of which have been illustrated, the dispensing device, due to the specific shape of the portion for receiving the roll of material, provides an easy access for the operator's fingers into the volumetric space (V) which has been defined with the flap (2). In all cases, the grabbing of the strip of material is extremely easy, with no risk of wounding the fingers of the operator's hand, the material being dispensed flat.
