摘要:
A modular multiple dispenser consists of tow or more identical dispensing units (D, D’) rigidly connected through two connecting members (C, C’) that engage corresponding seats (CS, CS’) formed on the rear of said dispensing units (D, D’). The dispenser may include one or more covers (S) suitable to slide from a dispensing unit (D) to an adjacent dispensing unit (D’), each cover (S) being substantially C-shaped and slidably mounted on the dispensing units (D, D’) through rear terminal legs (LL, SL, SL’, LL’) that engage relevant guide ribs (R, R’) formed on the rear of the dispensing units (D, D’).

A feeding and cutting unit for a dispenser of paper sheets obtained from a continuous band comprises a supporting structure (1, 2, 3) that rotatably supports a feeding roller (4) which in turn internally rotatably supports a shaft (5) parallel thereto which carries a blade (6) that during the rotation of the blade-carrying shaft (5) projects through a corresponding longitudinal slot formed in the feeding roller (4), the unit including a pair of constantly engaged end gearings formed by a first toothed wheel (7) integral with and coaxial to the blade-carrying shaft (5) and a second toothed wheel (8) formed on the supporting structure (1, 2, 3) at a position coaxial to the axis of rotation of the feeding roller (4). In this way, a simplification of the unit is achieved as well as a greater reliability and smoothness of operation guaranteed by the constant engagement whereby there are no problems of synchronized rotation of the blade-carrying shaft (5) and of the feeding roller (4) regardless of plays or wear that may rise over time.

An element for adjusting the width of the outlet (11) in paper towel dispensers (10) consists of a single piece molded in a plastic material having resilience features, in two specular left (1a) and right (1b) versions, which is substantially C-shaped with two lugs extending from a central body. Said lugs are parallel and spaced by a distance substantially equal to the thickness of the bottom wall (12) of the dispenser (10) in the area where the outlet (11) is formed, so as to enclose said area between a first lug of smaller extension on the outer side and a second lug of greater extension on the inner side. The inner lug carries a securing member suitable to couple with any of a plurality of mating fixing members provided close to the outlet (11) of the dispenser (10), so as to reduce by an adjustable extent the free width of the outlet.

A dispenser for pasty detergents includes a socket (A) for introducing a detergent container and a chamber (G) in communication with the socket (A) through a one-way detergent inlet valve and with the outside through a one-way outlet valve, a pressure and a vacuum being alternately created in said chamber (G) through a pump (P) provided with a return spring (S). Each of said one-way inlet and outlet valves consists of a membrane (M; V) made of an elastically deformable material and provided with a central bore, and of a corresponding conical shutter (N; Z) suitable to close said bore. The central portion of the membrane is thicker so as to have a greater rigidity, whereby in the closing return motion when it abuts against the conical surface of the shutter (N; Z) it cuts the residual film of detergent possibly remaining and achieves a perfect tightness without risk of dripping.

Mechanism for cutting and distributing portions of sheet, particularly paper towels, comprising at least one cylinder (9) which can rotate around its axis in a supporting structure (1,2,3) and drag an end portion (8) of at least one sheet, inside said cylinder (9) being arranged one or more movable blades (28) which can protrude outside the cylinder (9) for cutting said end portion (8) of the sheet and are fixed to a shaft (26) suitable for rotating around an axis parallel to the longitudinal axis of the cylinder (9), wherein said shaft (26) is provided with at least a first member (30) which protrudes from one side of the cylinder (9) and can be rotated for an arc of a circumference by at least a second member (25) which shifts in a direction parallel to the longitudinal axis of the shaft (26) of the movable blades (28) and rotates around the axis, the rotational-translational motion of this second member (25) being synchronized with the rotatory motion of the cylinder (9). Towel dispencer comprising said mechanism.
摘要:
A container device, dispensing lengths of paper by manual tearing from a roll, with a roll (B) in reserve, wherein two substantially parallel pins (4, 4') are provided for supporting and unwinding paper (10) from two rolls (A, B) with two openings (20) corresponding to said pins (4, 4') in the lower portion of the device housing, comprises a member (5) shaped as a sector of circle and freely rotatable about one of said pins (4, 4') being provided with a peripheral flange (5a) shaped as an arc of circle and adapted to obstruct the corresponding opening (20) at the same side when said sector (5) is kept at a first, substantially vertical position. A spring (15) urges the sector (5) to rotate until reaching a second position of rest at which the opening (20) on that side is made accessible, there being provided lever means (6) for keeping the sector (5) in said first position until a follower thumb (8), attached to said lever means (6) comes into contact with the roll core upon roll exhaustion, whereby the sector (5) rotates to said second position to make accessible the corresponding opening (20).
