Abstract

Disclosed herein is a plastic wall-mounted dispenser primarily for coreless rolled sheet material and in which the plastic material, typically polypropylene, from which the dispenser is made is somewhat yieldable under stress. The dispenser is mounted in cantilevered relationship to the wall and the weight of the dispenser and its contents and pressures exerted thereagainst by the act of dispensing sheet material therefrom causes stresses which tend to twist the dispenser and open the latches by which the base and cover sections of the dispenser are latched together. To rigidify the structure, the base portion of the dispenser is formed in the shape of a hollow truncated pyramid which gives it an inherently strong beam configuration. The cover portion may also be formed in part in the shape of a hollow truncated pyramid. The latches comprise two snap latches proximate the corners formed by intersecting walls of the truncated pyramidal hollow base section so that these corners rigidify the latch assembly and reinforce the latches against distortion and release under stresses imposed upon the dispenser.

Claims

1. A sheet material dispenser adapted to be mounted on an upright wall and having a mounting base section and a cover section, a hinge interconnecting said sections so that the cover section may be swung away from the base section to load sheet material thereinto, latch means for latching the two sections together when the cover section is swung closed, said cover section being supported by the base section in cantilevered relation to said upright wall to impose the weight of the loaded dispenser and pressures developed by dispensing sheet material from the dispenser on the base section, said sections comprising plastic material which is yieldable under stress, said base section having a flat base panel adapted to be fastened to the upright wall and side and end panels extending at obtuse angles from the base panel and intersecting one another to form angled corners and to constitute the base section as a truncated pyramid enclosing a hollow space and having inherently strong beam configurations to withstand the pressures exerted thereon without sufficient change of shape to release the latch means when the dispenser is mounted, loaded and is use, said side panels having edges spaced from the base panel, said hinge being disposed on the edge of one side panel and the latch means being disposed on the edge of the other side panel whereby to space the hinge and latch means from said upright wall, said latch means comprising two snap latches proximate the corners formed by the intersecting side and end panels of the base section.

2. The dispenser of claim 1 in which the sheet material comprises a coreless roll, the bottom panel of the base section of a mounted dispenser constituting an inclined ramp urging a diminished roll forwardly away from contact with the flat base panel.

3. The dispenser of claim 1 in which the cover section is in the shape of a truncated bent pyramid.

4. The dispenser of claim 1 in which said cover section has a flat panel with a dispensing slot formed therein and has side and end panels extending at obtuse angles from the base panel and intersecting one another to form angled corners.

5. The dispenser of claim 4 in which the side panels of the cover section have longitudinal angle bends to stiffen the cover section.

6. A sheet material dispenser adapted to be mounted on an upright wall and having a mounting base section and a cover section, a hinge interconnecting said sections so that the cover section may be swung away from the base section to load sheet material thereinto, latch means for latching the two sections together when the cover section is swung closed, said cover section being supported by the base section in cantilevered relation to said upright wall to impose the weight of the loaded dispenser and pressures developed by dispensing sheet material from the dispenser on the base section, said sections comprising plastic material which is yieldable under stress, said base section having a flat base panel adapted to be fastened to the upright wall and side and end panels extending at obtuse angles from the base panel and intersecting one another to form angled corners and to constitute the base section as a truncated pyramid enclosing a hollow space and having inherently strong beam configurations to withstand the pressures exerted thereon without sufficient change of shape to release the latch means when the dispenser is mounted, loaded and in use, the hinge being disposed at one side of the dispenser and the latch means comprising two snap latches located at the other side of the dispenser and proximate the corners formed by the intersecting side and end panels of the base section, the hinge being disposed at the bottom of the wall-mounted dispenser and the latches being disposed at the top of the wall-mounted dispenser whereby the cover section will swing downwardly about the hinge to form a tray to receive and support sheet material in the course of loading the dispenser.

7. The dispenser of claim 6 in which said snap latches comprise jaw means formed on the edge of a side panel of the base section which is uppermost when the dispenser is wall mounted, said cover section having a panel with an edge having a tooth embraced by said jaw means when the dispenser is closed.

8. A sheet material dispenser adapted to be mounted on an upright wall and having a mounting base section and a cover section, a hinge interconnecting said sections so that the cover section may be swung away from the base section to load sheet material thereinto, latch means for latching the two sections together when the cover section is swung closed, said cover section being supported by the base section in cantilevered relation to said upright wall to impose the weight of the loaded dispenser and pressures developed by dispensing sheet material from the dispenser on the base section, said sections comprising plastic material which is yieldable under stress, said base section having a flat base panel adapted to be fastened to the upright wall and side and end panels extending at obtuse angles from the base panel and intersecting one another to form angled corners and to constitute the base section as a truncated pyramid enclosing a hollow space and having inherently strong beam configurations to withstand the pressures exerted thereon without sufficient change of shape to release the latch means when the dispenser is mounted, loaded and in use, said cover section comprising a front panel having a dispensing slot and side and end panels extending from the base panel to enclose a hollow space therebetween, the hollow space within the cover section being larger than the hollow space within the base section and the hinge and latches being disposed asymmetrically to the respective base panels of the said base section and cover section and closer to the base panel of the base section than to the front panel of the cover section, said latch means comprising jaw means including tangs on the inside edge of the side panel of the base section which is uppermost when the dispenser is mounted and out of contact with a full roll of sheet material by reason of the asymmetric location of the latches.
