SYSTEM AND METHOD FOR ROLLS WITHOUT NUCLEO OF PAPER PRODUCTS.

BACKGROUND OF THE INVENTION Field of the Invention This invention relates to the field of commercial and consumer absorbent paper products, which include toilet paper and paper towels. More specifically, this invention relates to an improved dispenser and method for dispensing a roll of absorbent paper product without core or core.

Description of Related Technology Commercial and consumer absorbent paper products such as the toilet tissue and paper towels are typically dispensed and dispensed in a roll form, and almost always include a cylindrical and hollow core around which is wrapped the product. The core is usually some type of cardboard which is attached to the product so that the core remains intact and the product does not separate from the core. The product is then stocked by mounting the roll on a spindle, such as can be found in toilet paper fountains, which pass through or otherwise penetrate the interior space of the core. Some dispensers include plugs that penetrate the hollow space within the core for a limited extent, as demonstrated in U.S. Patent Nos. 390,084 and 2,905,404 to Lane and Simmons, respectively.

Recently, non-core toilet tissue rolls have appeared on the market, primarily in Europe, which are wound through the full diameter of the roll, there are several advantages and disadvantages associated with coreless rolls. Coreless rolls are ecologically superior to core rolls since fewer adhesives are used to make the product, and more product can be provided in the space that would otherwise be occupied by the core. Rolls with a core are more expensive to manufacture than rolls without a core due to the expense of making the cores and joining the cores to the product. Furthermore, coreless rolls have the advantage of being less pillage objects in commercial places due to their inherent incompatibility with conventional pumps.

On the other hand, there are problems of assortment with the coreless rolls that until now have been difficult to overcome. Conventional dispensers for coreless rolls typically include an enclosed support surface on which the roll is supported as it is turned and an opening through which the product is passed. Although they are functional, these pumps have some undesirable characteristics, including a lack of ability to control the drag to remove the product; the fact that the product actually touches the interior of the dispenser, which may be considered non-sanitary by some consumers; and the lack of ability to provide 180 ° product access to the consumer. It is clear that there is a need for an improved system and method for supplying coreless rolls of consumer paper and absorbent paper products.

Synthesis of the Invention Therefore, it is an object of the invention to provide an improved system and method for dispensing coreless rolls of consumer paper and absorbent paper products.

In order to achieve these and other objects of the invention, an assembly for dispensing a coreless roll of a paper product for the absorbent consumer such as a tissue for the toilet includes, according to a first aspect of the invention, a frame; a mounting mechanism to allow the frame to be mounted on a stationary surface in a wall; and a coreless securing mechanism for securing a coreless roll of paper tissue to rotate within the frame, the core and core securing means comprise at least one projection that is constructed and arranged to penetrate the inside of the roll no core between the adjacent layers of the coreless roll so as to prevent radial displacement of the coreless roll with respect to the frame during use, whereby an ecologically responsible coreless absorbent paper roll product can be dispensed which can be dispensed without fear of a radial displacement as reliably as can be done with respect to a roll of product conventionally with core.

According to a second aspect of the invention, a method for installing a coreless roll of an absorbent consumer paper product in a dispenser includes the steps of (a) orienting the coreless roll to a desired alignment position within from a supplier; and (b) securing the coreless roll to the spout by penetrating the coreless roll with at least one projection penetrating between the adjacent layers between the paper product in a coreless roll where the coreless roll is secured in the core. against radial displacement with respect to the jet by operation.

According to a third aspect of the invention, a method for installing a coreless roll of an absorbent consumer paper product in a dispenser includes the steps of (a) placing the coreless roll in the spout on a temporary retention mechanism to the coreless roll to a desired alignment position within the spout; (b) securing the coreless roll to the spout so that the coreless roll will be mounted to rotate with respect to the spout; and (c) removing the temporary support mechanism from the coreless roll, so that the coreless roll will be allowed to rotate without being impeded by the temporary support mechanism.

Finally, according to a fourth aspect of the invention, an assembly for dispensing a coreless roll of an absorbent consumer paper product includes a temporary support mechanism for orienting the coreless roll to a desired alignment position within the dispenser.; an assurance mechanism for securing the coreless roll to the spout so that the coreless roll will be mounted to rotate with respect to the spout; and a release mechanism for removing the temporary support mechanism out of the coreless roll after the coreless roll has been secured by the securing mechanism, whereby the coreless roll will be allowed to rotate without being prevented by the temporary support mechanism.

These and various advantages and elements of novelty characterizing the invention are pointed out with particularity in the appended claims herein and form a part thereof. However, for a better understanding of the invention, its advantages, and the objects obtained by its use, reference will now be made to the drawings which form an additional part of this, and to the accompanying descriptive matter in which it is illustrated and a preferred embodiment of the invention is described.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES Referring now to the drawings, wherein the like reference numbers designate a corresponding structure through the views, and referring in particular to Figures 1-4, a set 10 for supplying a coreless roll 12 of an absorbent paper product for the consumer such as a toilet tissue includes a frame 14 having a mounting hole 16 defined therein to allow the frame to be mounted on a stationary surface, such as a wall. The assembly 10 further includes a roll and core securing mechanism 18 for securing a coreless roll 12 of the toilet tissue for rotation within the frame 14. In the embodiment shown in Figures 1-4, the mechanism for securing rolls and core 18 includes a first arm 20, a second central arm 22 and a third arm 24 as best seen in Figure 1. The assembly 10 shown in Figures 1-4 is designed to accommodate 10 rolls of tissue for toilet no core, much in the way of many conventional dispensers that are available for commercial application. The outer arms 20 and 24 are constructed of an elastic material such as a spring steel, and are configured so that they will be displaced when a coreless roll is secured between the central arm 22 and the respective outer arms 20 and 24. In this In this manner, the outer arms 20 and 24 will press the respective coreless roll 12 towards the central arm 22 in a manner that will be described in more detail below. An important advantage of the invention is that the roll and core securing mechanism 18 is designed to prevent a radial displacement of the rolls and the core 12 with respect to the frame 14 of the assembly 10 during use, so that the roll No core can be stocked without fear of radial displacements during use as reliably as a roll of absorbent paper product with conventional core can be dispensed. In the preferred embodiment, this is achieved by providing the pressure plates 28 on the inner surfaces 26 of the respective arms 20, 22 and 24 securing mechanism 18. Advantageously, a number of projections 30 preferably but not necessarily more than one, they extend inward from the respective pressure plates 28 to where the coreless core 12 of the tissue will be maintained during operation. The projections 30 are specifically designed to penetrate the coreless roll between the adjacent layers of the coreless roll to prevent radial displacement of the coreless roll during use. It will be appreciated that the pressure provided by the elasticity of the arms 20 and 24 will assist the projections 30 to penetrate between the adjacent layers of the coreless roll and improve the securing of the coreless rolls of the assembly 10 during use.

The pressure plates are preferably mounted with respect to the respective arms 20, 22 and 24.

This can be achieved by means of a bearing bolt 32 as shown in Figure 1. Other known mechanical arrangements can be provided to achieve this effect as well.

Preferably, the assembly 10 includes a cover 34 that is hinged to the frame 14 by a hinge 35, best seen in Figures 2 and 3. A sliding window 36 is provided in the cover 34 to selectively expose the roll 12 of the coreless tissue that it is being stocked at a particular point in time, and to deny access to another roll or casting site. The cover 34 and the sliding window 36 are conventional.

An important aspect of the invention is that in the embodiment of Figures 1 and 4, the assembly 10 is provided with a temporary support mechanism 38 for supporting a coreless roll 12 in an alignment position with respect to the securing mechanism. , specifically with respect to the pressure plate 28, when the coreless roll 12 is being installed in the assembly 10. As best seen in Figures 2 and 3, the temporary support mechanism 38 preferably includes a platform 40 to hold the coreless roll 12 having an inner surface 42 which is curved to approximate the outer circumference of the roll 12. The roll 12 will be cuneaged relatively immobile on the inner surface 42 of the platform 40 during the installation of the roll 12 in the assembly 10. The platform 40 is configured to pivot with respect to the frame 14 around a pivot tip 44, better seen in Figures 2 and 3. A rod of push 46 connects a lower part of the platform 40 with a second part 52 of a swing arm 48 as shown in Figures 2 and 3. The swing arm 48 is mounted to pivot with respect to the frame 14 at a pivot point 54 and it also includes a first part 50 which is designed to make contact with a contact surface 60 on an interior surface of the cover 34 when the cover 34 is being closed as can be seen in figures 2 and 3. The first part 50 of the oscillating arm 48 is pressed with respect to the frame 14 by means of a tension spring 56 which is mounted between a first part 50 and a fixing point 58 on the frame 14. This pressing pushes the swing arm 48 to pivot in a right direction to left around the pivot 54 and therefore tends to push the platform 40 to the position shown in figure 2, where it will make contact with the outer circumference of the roll I read 12 in an alignment position with respect to the pressure plates 28 of the coreless roll securing mechanism 18. However, when the cover 34 is closed, as can be seen by comparing Figure 3 to Figure 2, the The first part 50 of the swing arm 58 will be pushed in a left-to-right direction around the pivot point 54 by contacting the first part 50 with the contact surface 60 on the cover 34. The full oscillating arm 48 will therefore move in a direction from left to right, causing a second part 52 of the swing arm 48 and the push rod 46 to rotate the platform 40 in a right to left direction with respect to the pivot point 44. This will tend to remove the platform 40 of its position making contact with the coreless roll 12. Therefore, when the cover 34 is closed, the coreless roll 12 will be free to rotate without interference from the platform 4 0. The mechanism 62 which is used to grind the cover 34 in the closed position shown in figure 3.

Referring now to Figures 5-7, a set 64 for dispensing a coreless roll 12 of a consumer absorbent paper product such as a toilet tissue includes, according to a second embodiment of the invention, a frame 66, which is represented as a relatively simplified shield around the space where the coreless roll 12 will be placed during use. The frame 66 has a mounting hole 68 defined in a rear part thereof for mounting the assembly 64 to a stationary surface, such as a wall. The assembly 64 includes a roll and core securing mechanism 78 that is shown as a first arm 70 and a second arm 72, as best seen in Figure 5. A pair of plates 76 are rotatably mounted on the respective arms 70 and 72 and have the projections 74 thereon which are constructed and arranged to penetrate into the coreless roll 12 between the adjacent layers of coreless roll 12 in the manner described above with respect to the first described mode. Another advantageous feature in the embodiment of the invention is shown in Figures 5-7, the provision of a retraction mechanism 80 for retracting one of the pressure plates 76 so that the pressure plates 76 can move and separate during loading. and discharge of the roll and core 12 on and out of the assembly 64. As best seen in Figure 7, one of the pressure plates 74 is preferably spring-loaded by means of a compression spring 86 towards the face pressure plate. Opposite 76. A cam mechanism 84 is provided to retract the pressure plate 74 against the pressure of the spring 86. In the illustrated embodiment, the cam mechanism 84 includes a knob 82 having a first cam surface 88, and a sleeve 85 having a second opposed cam surface 90. When knob 82 is turned over, as shown diagrammatically in FIG. 7, the interaction of cam surfaces 88 and 90 will push the cam. The pressure plate 74 is rotatably mounted relative to the knob 82 by a bolt 96 that is secured to the pressure plate 84 and is secured to the pressure plate 74 outwardly from the face pressure plate against the pressure of the spring 86. free to rotate within the knob member 82. The bolt 96 has a head 94 that is provided with a detent 92 on the knob 82, as shown in Figure 7.

It is understood, however, that while numerous features and advantages of the present invention have been established in the foregoing description, together with details of the structure and function of the invention, the description is illustrative only, and changes in the detail may be made. , especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the general and broad meaning of the terms in which the appended claims are expressed.
