Abstract
Description
- The present invention relates to methods and devices for mounting paper rolls, in particular to methods and devices for mounting coreless paper roles on devices, such as printers, without damaging the paper roles.
- It is common for labels or paper used in printing to be in the form of a roll. The most common technology involves wrapping a continuous sheet of labels or
paper 400 around acardboard core 410 forming a cored roll, as shown inFIG. 11 . The core provides for structural support for the paper and labels, especially when the label or paper is unrolled from the core. Thecored roll 430 provides aninternal cavity 420 that enables the cored roll to be mounted to the apparatus by inserting an element in to the cavity. The core prevents the paper or labels on the internal part of the roll from becoming bent or damaged, and consequently technology involving mounting a cored roll is not very sophisticated, as the internal diameter of the core simply needs to interact with the external diameter of a mounting element. The core allows for the entire roll to be used, and serves as an efficient way to mount a roll of paper or labels, while providing structural integrity to the entire roll. - Nonetheless, technology is moving away from cored rolls, as rolls are now made without the internal core, as shown in
FIG. 10 . As with the cored roll, acoreless role 220 can be made of a continuous sheet of labels orpaper 240 and form aninternal cavity 210. Coreless rolls save on the use of material to make the inner core, which saves cost and packaging, and is beneficial as the inner core does not have to be thrown out. Coreless rolls also have the advantage of having more labels per roll as coreless rolls are not limited by the internal diameter of the cores. The drawbacks to coreless rolls are that they suffer from lack of structural support and protection that the core provides. Another issue is that coreless roles are being mounted on elements that are designed to receive cored roles. One feature of a coreless role is that theend 230 of the rolled label or paper that forms the internal diameter of the role hangs free within the cavity of the role. As a result, when a coreless role is mounted on an element that is designed to receive a cored role, the mounting element will bend or damage thefree end 230 of the paper forming the internal diameter of the coreless role. These problems with coreless rolls lead to inefficient use of the coreless roll, uneven delivery of the labels, and difficulties with mounting a coreless roll onto an apparatus, such as a printer. -
FIG. 9 depicts an example of a commercially available printer designed to dispense a cored roll.Printer 300 comprises a pair of spring loadedmounting elements 310 that exert a force in the direction ofarrows Mounting elements 310 comprise a plurality ofledges printer 300, themounting elements 310 are moved in a direction oppositearrows ledges mounting elements 310 are brought together in the direction ofarrows mounting elements 310 are in contact with the paper roll and eitherledge - Mounting elements such as those depicted in
FIG. 9 , are not adequate for securing a coreless paper roll toprinter 300. When the axis of a coreless paper roll is aligned with the axis formed byledges mounting elements 310 are brought together, ledges 312, 314 will damage the free end of the paper forming the internal diameter of the coreless role. - What is needed is a mounting apparatus that enables a coreless roll to be mounted to a dispenser without damaging the free end formed in the cavity of the role. It would be beneficial if the mounting apparatus were in the form of an adapter that secures the enables a coreless role to be secured to a dispenser designed for cored paper roles.
- Accordingly, it is an object of the present invention to provide an apparatus for mounting a coreless roll that comprises a first and/or second component with a roll mounting surface comprising a radius that is substantially equal to the inner radius of the roll such that the roll mounting surface supports the coreless roll when the roll mounting surface is disposed within the cavity; and a tapered guiding surface coupled to a distal end of the roll mounting surface that transitions from a radius less than the radius of the roll mounting surface to a radius substantially equal to the radius of the roll mounting surface such that the tapered roll guiding surface guides a free end of the coreless roll formed in the cavity against the inner circumference of the roll when the apparatus is inserted into the cavity. It is preferable that the second component detachably couples to the first component.
- It is another object of the invention for the first and/or second components to comprise a base coupled to the proximal end of the mounting surface, wherein the base comprises an outer radius that is greater than the inner radius of the coreless role such that a surface of the base extending in the direction of the outer radius of the role comes in to flush contact with a surface of the role extending from the inner radius to the outer radius with the mounting surface is disposed in the cavity. The base can comprise a coupling element that detachably secures the proximal end of either component to a mounting element that supports the apparatus. The base can further comprise a friction surface, such as friction bumps, disposed on a surface of the base extending in the direction of the outer radius opposite the base contact surface.
- It is a further object of the invention for the first and/or second components to comprise an introduction element that detachably couples the first and second components. Preferably first and second introduction elements couple the first and second components. Such an embodiment can be provided by a first introduction element with a cavity that is open towards the distal end of the first introduction element and comprises a threaded surface on an inner surface of the first introduction element forming the cavity, the second introduction element comprises a threaded surface on an exterior surface forming the second introduction element, and the first and second components are detachably coupled by aligning the distal ends of the first and second components and radially rotating the first component relative to the second component such that the first and second components move in an axial direction.

Introduction elements second components 21, 1 into thecore 210 of the coreless role. In order to assure that thefree end 230 of the role is not damaged by the introduction elements, the outer radii of these elements are less than the internal diameter of the coreless roll. The outer radii of these elements should be sufficiently small such that theintroduction elements free end 230 when the introduction elements are inserted in tocavity 210. Preferably, the outer radii of these elements are small enough such that they do not come into contact with thefree end 230. -
Introduction elements second components 21, 1 to be detachably coupled together. As shown in the preferred embodiment ofFIG. 1 ,first component 21 comprises acavity 27 that is open towards the distal end of thefirst introduction element 22 and comprises a threadedsurface 24 on the inner surface of thefirst introduction element 22. Second component 1 comprises a threadedsurface 4 on the exterior surface forming the second introduction element and an outer diameter that corresponds to the inner diameter ofcavity 27. The first andsecond components 21, 1 are detachably coupled by aligning the distal ends of the first and second introduction elements such that the second introduction element is disposed withincavity 27 and radially rotating the components relative to one another. The radial rotation of the components will cause the components to move in an axial direction such that the components are drawn together and enable thecoreless roll 220 to be secured to the mounting apparatus. -

Bases friction elements 30 on the outer surfaces of the bases.FIGS. 3-6 illustrate that these friction elements are preferably friction bumps that arranged as an array of bumps in a two tiered circular pattern. Preferably the mounting apparatus serves as an adapter that enables a coreless role to be effectively mounted to existing dispensing apparatuses, such as a printer, for cored rolls. These pre-existing dispensing apparatuses typically comprise geometrical restrictions that limit the amount of space that can accommodate an adapter. For instance, the dispensing apparatus may be limited in the length of a roll that can be mounted to the apparatus. Such restrictions require that the base be thin. However, since the depicted embodiment requires the components to be radially rotated in order for the coreless role to be secured to the mounting apparatus, a thin base makes it difficult to ensure thatsurfaces surfaces 250 of the roll. As a result,friction elements 30 provide a surface that enables a user to press their palms against the bases and further rotate the components relative to one another. While the preferred embodiment depicts bumps that extend away from the outer surfaces of the bases, alternatively the score marks, dimples or other elements that change the topography of the outer surfaces can be included with or substituted for the bumps.

However, many alternative designs and structural arrangements are possible without departing from the principle of the invention. The scope of the present invention should therefore not be limited by the embodiments illustrated, but rather it should be understood that the present invention has wide applicability with respect to mounting apparatuses for coreless roles. All modifications, variations, or equivalent elements and implementations that are within the scope of the appended claims should therefore be considered within the scope of the invention.
