Problems solved by technology

Another problem encountered is that the base panels tend to rotate or skew around each other about the lock, which can also cause the lock to tear or disengage, thereby destroying the integrity of the packaging board carton, so that it is not suitable for packaging and sales purposes. completely ineffective

Embodiment Construction

[0028] Referring to the accompanying drawings, especially figure 1 , shows a blank 10 formed from cardboard or board having a similar function. In this embodiment, the blank is of the well-known roll-to-roll type to be packaged around a set of containers, such as a set of cans "P" ( figure 2 ). The elongated blank 10 continuously comprises a first base panel 12, a first side wall panel 14, a top end panel 16, a second side wall panel 18, and a second base panel 20 along successive transverse fold lines 22, 24, 26 and 28, respectively. hinged to each other.

[0029] In one embodiment, bottom retaining holes are formed in the first bottom panel 12 and first side wall panel 14 along the transverse fold line 22 in part in order to prevent the forward movement of the item when it is received in the sleeve formed from the blank. 30, 32. The bottom holding holes are reinforced by hinged tabs 30a, 32a respectively. Similar bottom retaining holes 34 , 36 are partially formed in t...

Abstract

A carton of the wrap-around type has a pair of overlapped base panels (12,20). One of the bases panels (12) which carries a locking tab (38) overlies a tongue (42) protruding from the end edge of the other base panel (20). The protruding tongue (42) is formed with a complementary locking aperture (40) engaged by the locking tab (38) to secure the overlapped panels (12, 20) together. On either side of the locking tab (38), the said one base panel (12) has a hinged tab (50, 52) protruding from the end edge of that panel. Each of the hinged tabs underlies the end edge (44,46) of the other base panel (20), one on each side of the protruding tongue (42). This over and under' arrangement presents less of an externally overlapped edge than is the case of a simple complete overlap and thus mitigates against the base panels being skewed or prized apart leading to tearing and / or dislodgment of the locking means.

Description

Background technique [0001] The present invention relates to a carton having overlapping bottom panels and a blank for forming the carton. More particularly, the present invention relates to a roll-to-roll packaging carton in which base panels are overlapped and secured together by integral punch locks. Punch locks are well known and comprise a locking tab formed in one of the base plates which passes through and is secured in locking engagement with a receiving aperture which is secured by a hinged wing of the other base plate. formed by the sheet. [0002] In packing board cartons with an integral center punch lock securing the bottom panels together, two problems were found to exist. One problem involves the lock being prone to tearing, which sometimes occurs when the base panels are pried out of face-to-face relationship with each other, for example when packing board cartons are stacked on supermarket shelves which have exerted a tear on the lock Tendency to stress.
