ABSTRACT:
This invention relates to dislays for displaying articles and more particularly, to paperboard gravity feed displays for displaying articles at point of sale locations.
Gravity feed paperboard displays are known. Such displays comp paperboard sheets formed into elongated channels for feeding square or rectangular products such as film packs and disposable cameras for example. The product is placed into the channel from the top of the tube. At the base is an opening and a shelf on which the product rests due to gravity force on the product in the channel, which is vertical. The product is removed manually from the opening, one at a time. Such feed tubes are relatively simple and comprise one piece construction in which a flap along the tube length is folded over and glued to a mating wall of the tube.
A need is seen for an improved feed tube construction wherein the glue is not essential and no additional components are required, to thereby reduce cost of the display.
A one piece paperboard display for feeding articles to be dispensed by gravity according to the present invention comprises a paperboard tube having a rectangular chamber for storing and feeding articles. The tube has an elongated front wall, first and second opposing side walls, the first side wall being hinged to the front wall at a first foldline and the second side wall being hinged to the front wall at a second foldline distal the first foldline, and a rear wall formed by a first panel hinged to the first side wall and a second panel hinged to the second side wall, the first and second panels being juxtaposed with the first panel being exterior and second panel being interior. A shelf is secured to one of the wall adjacent to the bottom end of the walls and form a bottom wall of the chamber for supporting articles in the chamber when vertical. Locking tab means are coupled to the first and second panels to releasably secure the juxtaposed panels together to form a collapsible tube. Thus no glue or other parts are necessary to secure the walls and panels together forming a simple collapsible feed tube.
In one aspect the locking tab means comprises a tab on the inner panel and a tab locking opening in the outer panel for receiving and releasably securing the tab to the outer panel.
According to the length of the tube, a plurality of the tabs and locking openings may be included.
