Description

TECHNICAL FIELD

The present invention concerns dispensers for handkerchiefs, napkins or other cellulose products in sheet form. Embodiments disclosed herein in particular relate to dispensers for handkerchiefs or other cellulose products in sheet form, typically folded or interfolded, having a rectangular prismatic form adapted to contain a stack or pack of rectangular sheets, for example interfolded tissues.

BACKGROUND ART

Disposable napkins or handkerchiefs are often products in packs or stacks containing interfolded handkerchiefs, folded so that, once inserted in a dispenser, it is possible to extract single napkins or handkerchiefs one at a time through an opening of the dispenser. Parallelepiped shaped dispensers, with an upper wall provided with an opening through which the handkerchiefs are picked up, are often used to contain and dispense the handkerchiefs.
In the present context, upper and lower are meant as the positions taken by the dispenser or by parts thereof in a possible and preferred configuration for use. Typically, these dispensers are configured to be used resting on a surface with a lower wall or base of its own, opposite which is the upper wall provided with the dispensing opening.
In some current state of the art dispensers the upper wall, provided with the opening for picking up the handkerchiefs, consists of a moving plate mounted so as to slide inside the dispenser in a vertical direction (when in use) from a top position, when the dispenser is full of handkerchiefs, i.e., contains a new stack of handkerchiefs, to a bottom position, when the dispenser is empty. The plate is maintained constantly in contact with the upper face of the pack or stack of napkins contained in the dispenser as a result of gravity.
Devices of this type are described in U.S. Pat. Nos. 1,464,180, 3,269,593, 3,346,141 and WO2015/088401.
It would be desirable to improve and perfect dispensers of the current state of the art to obtain a more functional and low-cost dispenser.

SUMMARY OF THE INVENTION

To completely or partially solve the problems and limits of dispensers of the current art, there is provided a dispenser of napkins or other typically folded and inter-folded cellulose products in sheet form, comprising a prismatic container defined by: a substantially rectangular bottom wall; a first pair of opposite lateral walls; and a second pair of opposite lateral walls. Each lateral wall extends from the bottom wall toward a respective upper end edge. The upper edges of the lateral walls surround an upper opening of the prismatic container, opposite the bottom wall. The dispenser further comprises a substantially rectangular closing plate, comprising an opening for picking up handkerchiefs contained in the prismatic container. The closing plate is adapted to slide in the prismatic container along the lateral walls. Characteristically, each lateral wall of the first pair of lateral walls comprises a respective cutout extending in a direction oriented from the upper opening toward the bottom wall. Two opposite edges of the rectangular plate comprise a respective appendage adapted to be slidingly engaged along a respective one of said cutouts.
In the present description, specific reference will be made to “handkerchiefs”. It must be understood that the dispenser according to the present invention can also be used to dispense other types of products in sheet form, typically cellulose products in sheet form and in particular folded and interfolded products in sheet form. In addition to handkerchiefs, examples of products of this type can also be napkins, facial wipes and similar products.
Each wall of the container is substantially rectangular. In the present description and in the appended claims “rectangular” is meant as a quadrangular or square shape, with right angles, which can nonetheless also have some elements that differ from a rectangle in the geometrical sense, such as appendages along one or more edges, rounded corners or the like.
The cutouts along the two opposite lateral walls, which in use are arranged vertically, act as guides for the extensions or appendages of the plate, which is thus guided in its vertical movement. The width of each of the two cutouts is substantially the same as, or slightly larger than, the dimension of the corresponding appendage in the direction of the edge from which said appendage protrudes.
The cutouts not only have a guiding function, but also allow the inside of the container to be viewed, for example in order to view the characteristics of the pack of napkins or handkerchiefs contained in the dispenser. For example, through the cutouts it is possible to check the type of napkins contained in the dispenser and the amount of products still available in the dispenser.
Each cutout can have a very limited width for example of a few millimeters, or even larger involving almost the whole of the width of the respective lateral wall. In advantageous embodiments the width of the cutout, and hence the corresponding dimension of the appendage provided on the respective edge of the plate, is from around 25% to around 50% of the width of the respective lateral wall.
A larger dimension of the cutouts allows better viewing of the content of the dispenser. Moreover, it reduces the amount of polymer material required to produce the dispenser and consequently the cost thereof.
Each cutout can start from a different height with respect to the bottom wall. Each cutout ends at the edge of the respective lateral wall, so as to form in substance a recess extending from the upper edge to an intermediate position of the lateral wall, close to the bottom wall or at the bottom wall. As each cutout ends at the edge of the lateral wall, the upper edge of the lateral wall is interrupted and this facilitates mounting of the upper plate.
The dispenser and the components thereof can be made of any suitable material. In advantageous embodiments, the container and the plate can be made of polymer material (plastic). Different materials can also be used for the walls of the container and for the plate, respectively. In some embodiments the material can be completely or partly transparent.
To prevent the plate from being accidentally separated from the container, for example during extraction of a handkerchief through the opening of the plate, one or more stops can be provided along one or more upper edges of the lateral walls. For example, and preferably, two stops are provided on two edges of opposite walls, for example the two lateral walls without cutouts.
The prismatic container can have a rectangular shaped base with a long side and a short side. To obtain an improved guiding effect, in some embodiments the walls with the cutouts are those arranged along the short sides of the bottom wall.
The opening of the plate is preferably narrow and elongated, in the manner of a slot. For example, the length can be at least four or five times the transverse dimension of the opening.
In some embodiments, the opening of the plate can have a rectangular shape, preferably with rounded corners.
In possible embodiments, the lower face of the plate, i.e., the face that in the configuration mounted for use is facing the bottom wall of the container, can have a rib extending along the opening of the plate. Preferably, the lower face of the plate has two substantially parallel ribs, one along each of two opposite edges of the plate opening. When the plate opening has an elongated, for example rectangular, shape, the rib/ribs is/are arranged along the long sides of the opening. The ribs, if present, have many advantages and functions. According to some aspects, the ribs can be adapted to stiffen the structure of the plate and/or to increase its weight, so as to facilitate descent of the plate by gravity onto the upper surface of the pack or stack of tissues contained in the prismatic container. Moreover, the rib/ribs reduces/reduce the mutual contact surface between the plate and the stack or pack of handkerchiefs, thereby facilitating extraction.

DETAILED DESCRIPTION OF AN EMBODIMENT

The dispenser, indicated as a whole with 100, comprises a container 1 approximately cubic or prismatic in shape and with a rectangular base. The dimension of the container 1 is such as to accommodate a pack or stack 20 of napkins or handkerchiefs (cf. FIGS. 4 and 5). The container 1 comprises a lower or bottom wall 2 from which lateral walls extend. More in particular, from the bottom wall 2 there extend two opposite lateral walls 3 and 4 and further two opposite lateral walls 5 and 6. In the illustrated embodiment, the walls 3 and 4 extend from the shorter sides of the bottom wall 2 which has an elongated rectangular shape. The walls 5 and 6 extend from the longer edges of the bottom wall 2.
Each of the two opposite walls 3 and 4 has a vertical cutout, i.e., orthogonal to the bottom wall 2. The cutouts are indicated with 10 and 11. Both the cutouts 10 and 11 extend up to the upper edges 3A, 4A of the respective walls 3, 4. In other words, the upper edges 3A, 4A of the walls 3 and 4 are interrupted at the cutouts 10 and 11.
Along the upper edges 5A and 6A of the lateral walls 5 and 6 two protrusions 16, 17 are provided, which form stops for a plate 8 described below.
The upper edges 3A, 4A, 5A, 6A of the lateral walls 3, 4, 5, 6 define an empty wall or upper opening 7 of the container 1. The opening 7 is closed by a plate 8 when the dispenser 100 is in use. The plate 8 has a rectangular shape substantially the same as the shape of the bottom wall 2 and of the upper opening 7 of the container 1. A respective appendage 14, 15 is provided along each of the short edges, indicated with 12 and 13, of the plate 8. Each of these appendages 14, 15 slidingly engages a corresponding one of said cutouts 10, 11. In this way, a guide system of the plate 8 along the lateral walls 3, 4, 5, 6 of the container 1 is obtained. To facilitate vertical sliding of the plate 8 in the inner volume of the container, delimited by the walls 3, 4, 5 and 6, the width of each cutout 10, 11 is preferably slightly larger than the length of the respective appendage 14, 15, i.e., of the dimension of said appendages in the direction parallel to the edge of the plate 8 from which they protrude.
In advantageous embodiments the plate 8 is very thin, to reduce the amount of polymer material required for its production. A perimeter edge, visible in particular in FIG. 3, can be provided to stiffen the plate 8. Preferably, the perimeter edge protrudes from the lower face of the plate 8, i.e., from the face that, in use, is facing the bottom wall, so as not to be visible.
The plate 8 has a central opening 9 for removing the handkerchiefs from the stack or pack 20. Preferably, the opening 9 has a rectangular and preferably elongated shape. In embodiments disclosed herein, as can be seen in particular in FIG. 3, ribs 18, 19 extend along the long sides of the opening 9 of the plate 8. The ribs 18, 19 extend from the lower face of the plate 8, i.e., from the face that, in use, is facing the inside of the container 1 and the bottom wall 2. The ribs 18, 19 are preferably joined with a rounded edge to the upper face of the plate 8, as can be seen in FIG. 2.
In mounted configuration, with the pack 20 of handkerchiefs inserted in the container 1, the ribs 18, 19 press on the upper surface of the pack 20 of napkins with a limited contact surface. On the one hand, this retains the pack of handkerchiefs and, on the other, provides a guide effect to facilitate removal of the handkerchiefs that are pulled by the user to be removed from the container 1. The purpose of the ribs 18, 19 is also to stiffen the plate 8, which acts as a cover of the container 1, preventing it from warping downward.
The perimeter edge of the plate 8 and the ribs 18, 19 provide the plate 8 with a structural strength without excessively increasing its weight and maintaining a reduced thickness. In less advantageous embodiments, the plate 8 can have a uniform thickness equal to the height of the perimeter edge and/or of the ribs 18, 19.
To load the pack or stack 20 of handkerchiefs into container 1 the upper closing plate 8 can be removed by appropriately tilting it with respect to the horizontal so as to move one of its long edges beyond the corresponding stop 16 or 17. After loading the stack of napkins the plate 8 can be repositioned in the container 2, with a movement opposite the one performed for its removal, making the plate 8 descend by gravity until it is resting on the stack or pack 20 of handkerchiefs. The user can then extract single handkerchiefs, picking them up through the opening 9 of the plate 8. As the stack 20 is consumed, the plate 8 descends by gravity toward the bottom of the container 1.
