Definitions

• This invention relates to panel interlocking means for cartons for securing together a pair of panels, for example, adjacent overlapping panels of a paperboard carton. In some situations, these panels are provided by the opposite ends of a wrapper blank which are brought together in overlapping relationship and interlocked.
• Locking tabs which are struck from one end of the carton wrapper and which are arranged to be forced through corresponding apertures defined by retaining tabs, struck from an opposite end of a wrapper are well known.
• An example of such a lock is shown in Figure 1 and corresponds substantially to GB 1 598 367.
• a problem associated with locking tabs of this type is that when they are forced through the aperture, the shoulder portion 1, illustrated in Figure 1, is forcibly folded out of alignment with the remainder of the tab in order to pass through the aperture. This is undesirable as it weakens the locking tab.
• the machinery that punches the locking tab through the aperture fails to do so correctly or completely, the integrity of the tab is compromised resulting in a carton which can no longer be used or is unreliable in use. Moreover such incompleted locks can be difficult to detect prior to use.
• FIG. 1 A further example is illustrated in GB 2 156 785 and owned by the applicant of this invention.
• This document illustrates a wraparound carton with panel interlocking means comprising a locking tab which is required to be driven through an aperture. It is apparent from the drawings that the outer portions of the tab are forcibly folded out of alignment with the remainder of the tab during the locking procedure. The locking tab is propped up by a retaining tab and the base portion of the locking tab is disposed in second engagement with the locking edge of a locking aperture.
• the locking tab comprises a second locking edge adapted to interengage a second panel portion being spaced and opposed the first panel portion about the locking aperture.
• each panel portion is located adjacent one corner of the distal end of the locking aperture.
• the edge of the corner is curved.
• the cut line defining the locking aperture is shaped to provide a recess extending along part of a side edge of the locking aperture, which recess is adapted to receive the shoulder portion of said locking tab.
• the retaining tab comprises a protruding portion along its side edge.
• Main portion 21 extends beyond neck portion 20 towards free edge 18 and is separated from first panel 10 by a cut line 28 which connects cut lines 24 and 26 and to define the shape of the main portion which is preferably an "arrow head" shape.
• Neck portion 20 should be narrower in width than the adjacent part of shoulder portion 22 to define at least one locking edge 25 formed along the lower part of the shoulder portion.
• a retention tab 30 is struck from second panel 12 and is hingeably connected thereto by fold line 32.
• Fold line 32 is substantially parallel to and spaced from end edge 34 of panel 12.
• fold line 32 is separated by a cut line to make folding the retention tab easier.
• Retention tab 30 comprises a elongate portion 36 and separated from panel 12 by a pair of oppositely disposed cut lines 38, 40 which define side edges of the elongate portion 36 and are increasingly spaced apart towards the end edge 34.
• a cut line 42 defines a distal edge 37 of elongate portion 36 which in this embodiment is substantially parallel to fold line 32.
• cut lines 38 and 42 are interconnected by a curved cut line 44 to define a panel portion 43 adjacent the locking aperture.
• cut lines 40 and 42 are interconnected by a curved cut line 46 to define a second panel portion 45 adjacent the locking structure.
• the base of shoulder portion 22 is held in place by abutment with panel portions of the second panel, which in this embodiment are defined by the radius of curvature of cut lines 44 and 46, as the shoulder portions are broader than the locking aperture in a vertical or oblique positions. If the locking tab
