DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to paperboard devices for retaining a plurality of articles which taper inwardly toward their bases. An example of such an article is a pot of the type often used for dairy products such as yogurt, cream etc. When a sleeve is used to form a multipack of such articles, the heels of the articles require positive separation to retain pack integrity.
SUMMARY OF THE INVENTION
According to the present invention there is provided a paperboard retaining device for one or more pairs of articles arranged side by side in two rows, each article tapering inwardly towards its heel portion, the device having a top panel, oppositely disposed side panels hingedly connected to opposite edges of the top panel, and base panels hingedly connected to lower edges of the respective side panels, there being provided at least one locking device between the two base panels, which locking device comprises a primary lock and a secondary lock, in which comprises a locking panel connected to the first base panel by way of a first hinge, and which is substantially parallel to the hinge between the first base panel and its associated side panel, and a keel panel which is connected to the second base panel by way of a second hinge which is substantially perpendicular to the hinge between the second base and its associated side panel. The keel panel is constructed and arrange to be moved out of the general plane of the base into a raised position so as to be located between a pair of adjacent articles, and the locking panel hinged upwardly so that formations on the locking panel and keel panel interlock so as to be retained in their raised positions.
Preferably the locking panel extends through the space vacated by the keel panel which is moved into its raised position by the locking panel. With certain arrangements said cooperating formations of the secondary lock comprise a hook portion on the first locking panel and a notch formed in the keel panel.
In preferred arrangements the primary lock comprises interlocking elements located on the two base panels. Conveniently the interlocking elements comprise an edge formed in the second base panel by virtue of cut and a locking tab formed on the first base panel between two aligned third hinges which are parallel to the first hinge, the tab being connected to a second locking panel which extends between the first and third hinges, and in use is engaged behind said edge.
Preferably a further lock is provided to prevent the secondary lock from opening once engaged. In one embodiment a further hook portion is provided on the first locking panel adjacent the second locking panel, which further hook position engages in an additional cut defined in the second base panel.
A preferred feature is that the keel panel has a further hinge, parallel to the second hinge, thereby defining an angled part and a free part of the keel panel remote from the second hinge, which free part in use is in a plane substantially parallel to the general plane of the base of the device. Also, the angled part and the free part of the keel panel are contoured so as to follow the contours of the articles which are engaged by keel panels. Another feature is that the cooperating notch is formed in the angled part of the keel panel.
Ideally a locking device is provided between each adjacent pair of articles, and also location arrangement are provided for the heels and/or tops of the articles, which location means may be in the form of apertures or slots.
