Abstract
Description
- This invention is concerned with a carton or pack and a blank for forming same. More particularly, the invention is directed to a pack or carton adapted to receive an array of containers, typically bottles or bottled beverages, intended for use in star post crates. Star post crates are containers, typically of box-like configuration, in which packs of containers located therein become locked in a final configuration by means of a star-shaped post engaging inter-engageable panel formations in the panels of such packs or cartons. Star post crates are particularly useful in high speed and/or high volume packaging.
- Locking together some configurations of pack intended for star post crates presents difficulties. For example, in packs holding four containers such as bottles in a 2x2 array, at the base of the pack there is normally only space for one secure locking formation. After transport through an appropriate packaging machine, the pack is locked relatively loosely with only one locking formation, and then inserted into the star post crate, whereafter the pack becomes more securely locked through star post cut outs.
- Such arrangement leads to instability problems in the handling procedures of transportation from the packaging machine to the crate packer. We have now found that such instability problems can be lessened by providing supplementary locking formations within the star post cut outs of the pack. Preferably a standard locking formation is retained. Such arrangement provides a more stable pack able to reduce stability or integrity problems in transportation between the packaging machine and the crate packer.
- According to one aspect of this invention, there is provided panel interlocking means comprising a pair of male tabs formed from, and foldably connected to, a first panel to define at least in part a single aperture in the first panel, and a locking aperture defined in a second panel to receive and engage the male tabs, further comprising a female tab formed from, and foldably or removably connected to, the second panel to define at least in part the locking aperture, and a provisional locking tab formed from at least one of the male tabs to engage the female tab.
- According to a second aspect of this invention, there is provided panel interlocking means comprising a male tab foldably connected to a first panel, and a female tab formed from, and foldably or removably connected to, a second panel to define at least in part a locking aperture in the second panel for receiving and engaging the male tab, wherein the male tab is provided with a provisional locking tab for engagement with the female tab, the provisional locking tab being foldably connected to the male tab, the male tab being disposed in the plane of the first panel, the provisional locking tab being folded out of the plane of the male tab and engaged with the female tab, and wherein the female tab is disposed in the plane of the second panel and the provisional locking tab is received in and engaged with a provisional locking aperture in the female tab.
- According to a third aspect of this invention, there is provided a method of forming an interlocked pack, carton or wraparound which comprises folding a pack, carton or wraparound blank incorporating panel interlocking means as defined in the first aspect, around a plurality of containers, causing the blank to become at least partially interlocked, transferring the partially assembled pack, carton or wraparound to a star crate wherein the said male tabs and locking aperture are located adjacent to the base of the star crate, and causing a star post to engage an undersurface of said crate in a manner to project through to engage the said male tabs and cause said male tabs to pass through said locking aperture in a panel interlocking manner before withdrawal of said star post therefrom.
- In relation to the panel interlocking means, preferably the single aperture and locking aperture are arranged to receive a spacer post of a crate so that the engagement of the male tabs with locking aperture is ensured when the post is received in the apertures. Conveniently, the provisional locking tab is struck at least in part from the one male tab. Preferably the provisional locking tab is formed in part from the one male tab and in part from the other male tab. Conveniently the provisional locking tab may extend from the one male tab into the other male tab when the male tabs lie flat in the plane of the first panel.
- In relation to the panel interlocking means according to the second aspect of the invention, the provisional locking tab is preferably struck at least in part from the male tab. Conveniently the male tab is adapted to be folded out of the plane of the first panel to have one of its opposed sides/faces engaged with an edge of the locking aperture. Conveniently, the male tab may have a laterally projecting shoulder portion for engagement with an edge of the locking aperture. Preferably each male tab has a pair of laterally projecting shoulder portions for engagement with a comer position of the locking aperture.
- In relation to the method of forming an interlocked pack, carton or wraparound according to the third aspect of the invention; the pack, carton or wraparound comprises an arrangement suitable for containing an array of containers such as bottles and most preferably an array of 2x2 such containers.
- In order that the invention may be illustrated, more easily appreciated and readily carried into effect by those skilled in the art, embodiments of the invention according to the first, second and third aspects thereof will now be described purely by way of non-limiting example with reference to the accompanying drawings, and wherein:

- FIGURE 6 schematically depicts application of a pack, such as a pack illustrated in FIGURE 4, to a star post for interlocking the juxtaposed panels shown in FIGURES 2 and 3; and
- FIGURE 7 is an underneath plan view, corresponding to the view of FIGURE 5, of a fully assembled pack after interlocking of the overlying panels shown in FIGURES 2 and 3.
-
- Referring firstly to FIGURE 1 of the drawings, there is shown a blank suitable for forming a pack, carton or wraparound formed from paperboard or like foldable sheet material.
- The blank incorporates panels having panel interlocking means as defined in the first aspect of the invention. The carton blank 1 has a
top panel 2 provided betweenfold lines fold lines apertures 3 are, optionally, provided from which e.g. bottle tops can partly project in the finally assembled form. Thetop panel 2 is connected to first and secondside wall panels side wall panel 5 is connected to a first panel P1 by means of hinged connection alongfold line 6. - In some embodiments, the panel P1 is provided with a pair of
apertures 7 through which e.g. the base of containers such as bottles can project, in the finally assembled form of pack. - The panel P1 has a projecting
part 8 in which a conventional locking tab B is struck. The panel P1 is also provided with a single aperture S in the region of which a pair of male tabs M1 and M2 are provided. The male tabs M1 and M2 are struck from the panel P1 and between them a provisional locking tab A1 extends, which is cut so as to form a tab capable of projecting through a co-operating formation to be described in subsequently in connection with a second panel P2. - In this embodiment, each male tab M1 and M2 is provided with shoulder portions SH which extend in the plane of the panel P1 but project beyond the notional completed circumference of the single aperture S.
- At the distant end of the blank 1, a second panel P2 is provided which extends from and is hingedly connected to second
side wall panel 5a byfold lines 6a. At this region of the blank,corresponding apertures 7a are, optionally, provided through which parts of the underside of containers such as bottles can project in the fully assembled form of pack. - The panel P2 is provided with a co-operating formation B1 struck there from which acts as a receptor for the primary locking tab B described above. The panel P2 is also provided with cut lines defining an aperture L, wherein a female tab F is struck from the blank to lie within the boundaries of aperture L. Accordingly female tab F can be folded away or at least partially removed from panel P2 by use of appropriate means to be described subsequently.
- The female tab F is provided with a provisional locking aperture A2 struck from the tab which is of a shape and dimension to co-operate with the provisional locking tab A1 described above in connection with panel P1.
- With reference to FIGURES 2 and 3 of the accompanying drawings, enlarged details of the panels P1 and P2 just described are shown wherein the functional components can be more clearly ascertained.
- In order at least partially to assemble a carton, blank or wraparound from the blank of FIGURE 1,
side wall panels fold lines corresponding fold line 6a and panel P1 folded about itscorresponding fold line 6 in such a manner that panel P1 overlies panel P2 in an array whereby single aperture S is caused to align with female tab F in juxtaposition. - With reference to FIGURE 4, an assembled pack according to one embodiment of the invention is provided in a 2x2 array whereby four containers such as bottles V are housed within the pack in a wraparound fashion, the bases of the four bottles positioned adjacent to the panels respectively P1 and P2, the sides of the bottles V being protected by the
sidewalls top panel 2, whereby the tops of the bottles may at least partly project through therespective apertures 3 in the assembled pack. - With reference to FIGURE 5, an underneath plan view of a partially assembled pack in 2x2 array is shown, wherein panel P1 has been folded to overly its companion panel P2 in a partially locked configuration. In this arrangement the primary locking tab B has been inserted through the co-operating formation B1 within the secondary panel P2 in an interengaging manner to hold the panels P1 and P2 together. Moreover in this configuration the provisional locking tab A1 has been folded out of the plane of panel P1 to project through the provisional locking aperture A2 in female tab F which tab at this stage is still present and not removed or part folded.
- Accordingly in this configuration the panels P1 and P2 are coupled by two separate and spaced locking means which provides a more secure and more stable part assembled pack than arrangements wherein similar panels are interlocked by means only of a primary interlocking means such as the tab and co-operating formation B and B1.
- Accordingly in such arrangement the pack is less susceptible to accidental or unwanted opening with possible loss of contents in transit between packaging machine and crate packing assembly stage. It will also be appreciated that the male tabs M1 and M2 in this arrangement overly the female tab F in preparation for a more complete assembly and full locking of the members M1 and M2 within the aperture L to be formed upon partial removal or folding of the female tab F as described subsequently.
- Referring to FIGURE 6, the partially assembled pack (having partially interlocked panels P1 and P2 as in the FIGURE 5 configuration) is shown in a manner about to encounter a star post of a star crate assembly mechanism (not shown). The Figure depicts intended insertion of the star post into the principal interlocking assembly M1, M2, L, F which operation is normally completed when the packs containing the bottles V are loaded into a star crate (not shown) and the star crate is engaged by the projecting star post shown in the Figure.
- With reference to FIGURE 7, the underside of the fully assembled pack is shown in a view corresponding to the FIGURE 5 arrangement. It will be appreciated that both male tabs M1 and M2 have been caused to pass through the aperture L defined by at least partial removal of the female tab F in such manner that the shoulder portions of both male tabs M1, M2 have passed through to the remote side of the panel P whereby all shoulder portions SH of both male tabs rest within comer formations of the locking aperture L in a fully inter-engaged and locked manner. Of course it is envisaged that the carton could use male tabs of the half lock type comprising one shoulder and a corresponding aperture without departing from the scope of invention.
- In such fully locked configuration, the packs containing the array of containers V are even more stable so that the packs can easily be removed from their corresponding star crates (not shown) as and when required.
- Accordingly, after initial assembly involving interlocking of primary interlocking means B and B1 and provisional locking means A1 and A2 a partially locked pack is provided. It remains a simple matter of lowering the partly assembled packs onto a star crate packing assembly and causing star posts to project from a surface underneath the packs to cause displacement of the male tabs M1 and M2 and corresponding at least partial displacement or possible removal of the female tab F in a rapid panel-interlocking action.
- As will be appreciated from the arrangements particularly in FIGURES 5 and 7, the amount of material forming the base panels P1 and P2 can be reduced in that these need not comprise a full or complete rectangle. Final interlocking of the panels P1 and P2 can be undertaken in a one step process and whilst the packs are loaded within the star crates, given alignment and juxtaposition of tab F with single aperture S having male tabs M1 and M2 to provide an assembled star crate package with enhanced stability compared to known such packs locked with only one interlocking means.
- It will be recognised that as used herein, directional references such as "top", "base", "side", "upper" and "lower" do not limit the respective panels to such orientation, but merely serve to distinguish these panels from one another. Any reference to hinged connection should not be construed as necessarily referring to a single fold line only: indeed it is envisaged that hinged connection can be formed from one or more of one of the following, a score line, a frangible line or a fold line, without departing from the scope of invention.
- It should be understood that various changes may be made within the scope of the present invention, for example, the size and shape of the panels and apertures may be adjusted to accommodate articles of differing size or shape, alternative top and base closure structures may be used. The carton may accommodate more than one article in different arrays. Furthermore, the panel interlocking means can be applied to a variety of carton types, for example clip; fully enclosed or basket carriers, without departing from the scope of invention.
