Abstract

Packaging of a bottle (1) is provided by a re-useable thermoformed sheet (S) that is erected folded round the bottle (1) to totally enclose it circumferentially within four mutually-hinged longitudinal wall-sections (11-14), and contain it within a rectangular cardboard-carton (3). The bottle (1) nests conformably in recesses (21) of each wall-section (11-14) for its shock protection, each recess (21) incorporating cavities (22,23) of tiered form that decrease in cross-section with depth to establish cushioning buffers (24, 25) between the enclosed bottle (1) and the carton (3). The ends of each wall-sections (11-14) are each moulded with an upstanding flange (16-19) that is configured with a pattern of ridges with intervening grooves that nests ridge-within-groove with the patterns of ridges with intervening grooves of each other flange (16-19) at that end. Ridges (27-29) moulded to project transversely upwards within the recesses (21) provide resilience for cushioning the bottle (1), and the thermoformed sheet (S) when laid flat with its hinges (15) opened out and the recesses (21) opening upwards (21) can receive four bottles (41) side-by-side for storage, and have additional sheet-mouldings (44) loaded with bottles (47) stacked on top.

Description

PACKAGING FOR A BOTTLE

This invention relates to packaging and is concerned

particularly with packaging for use in protecting bottles against shock during storage and transit.

Various packaging methods have been used for protecting bottles together with their contents, during storage and transit. These methods, in addition to being generally labour-intensive, commonly involve a substantial outlay in cost and material-resources on packaging items in the form, for example, of cardboard cases and specially-designed items of foam or other forms of plastics, or corrugated cardboard, to fit within them. Much packaging of this nature cannot be re-used or re-cycled and goes to waste.

It is an object of the present invention to provide a form of packaging for bottles which can be re-used and can be adopted for secondary use when no longer required specifically as a packaging item.

According to the present invention there is provided packaging for a bottle wherein a thermoformed sheet is foldable

circumferentially round the bottle with the bottle nesting conformably within recesses in sections of the sheet spaced from one another circumferentially of the bottle for

protecting the bottle against shock, and wherein the sheet is adapted to lay flat with the recesses open upwardly to receive individual bottles conformably side by side.

The packaging of the invention can be readily re-used for its original purpose, but has a secondary use when laid flat, in the storage of bottles. More especially, where wine bottles are involved, the packaging can be readily adopted for use in the provision of a wine rack. An example of thermoformed packaging according to the present invention, will now be described with reference to the accompanying drawings, in which: Figures 1 and 2 are illustrative in side-elevation and plan respectively of three sequential stages in the packaging of a v/ine bottle within thermoformed packaging according to the present invention, in conjunction with an outer carton; Figures 3 to 5 are respectively a plan view, a side elevation and a sectional end-view of the thermoformed plastics sheet used in the packaging of the invention;

Figures 6 to 13 are illustrative of four successive stages in the packaging of a wine bottle within the thermoformed packaging of the invention, Figures 6 to 9 illustrating the four stages in sectional side-elevation (the section of Figure 6 being taken on the line V-V of Figure 3) , and Figures 10 to 13 illustrating the four stages in side elevation of the case; and

Figures 14 to 16 illustrate successive stages in use of thermoformed packaging of the invention for secondary use in the storage of bottles in a stack.

Referring to Figures 1 and 2, a wine bottle 1 is packaged within a thermoformed packaging case 2 to protect it from shock and damage, and the case 2 with the bottle 1 inside, is then entered into an outer, rectangular cardboard-carton 3. The packaging case 2 is of an elongate rectangular form, being erected from a one-piece thermoformed sheet S (for example of polypropylene) shown in Figures 3 to 5 , by folding it round the bottle 1 to be protected with the whole of the bottle 1 from its main body 4, shoulders 5 and neck 6 totally enclosed.

In the latter respect, and referring to Figures 3 to 5, the case has four substantially-rectangular moulded sections in the form of a base-wall 11, two opposite side-walls 12 and 13, and a top-wall 14, that are hinged together longitudinally in pairs by three hinges 15 moulded integrally with the paired walls. The walls 11 to 14 are moulded in the sheet S to have respective pairs of flanges 16 to 19 with the two flanges of each pair upstanding from opposite ends of the top or inside surfaces T of the walls 11 to 14. The outer surface 20 of each flange 16 to 19 is configured with a respective pattern of ridges with intervening grooves running side-by-side with one another round it.

The inside surface T of each wall 11 to 14 between its respective pair of flanges 16 to 19, is contoured in depth and width with a recess 21 that is configured in the moulding of sheet S to conform to the external contour of the bottle 1. Each recess 21 incorporates cavities 22 and 23 of oval and quasi-oval configuration respectively, which are set

orthogonally to one another with the cavity 22 smaller in both axes than the cavity 23, and which are both of a tiered or stepped form having cross-sectional dimensions that decrease with depth. The cavities 22 and 23 by virtue of their thermoforming , give rise on the bottom or outside surfaces B of the walls 11 to 14 to respective projections or buffers 24 and 25 that have cylindrically-concave bottom-faces 26 extending lengthwise of the respective walls 11 to 14. The buffers 24 and 25 act principally in the cushioning of the walls 11 to 14 of the case 2 and the bottle 1 contained by it, against external shock imposed on the surfaces B via the outer, secondary packaging carton 3. (The carton 3 may be replaced by a mailing bag or other external packaging, but the buffers 24 and 25, which may be of different heights to one another and of different shapes, serve the same shock- protection purpose.)

Additional cushioning of the bottle 1 against shock is provided by transverse ridges 27 to 29 moulded to project upwardly from the inside surfaces T into each recess 21 in locations corresponding to those of the neck 6, shoulders 5 and base of the body 4 of the bottle 1. The ridges 27 to 29 give added resilience or springing within the walls 11 to 14 of the case 2.

A four-stage sequence of packaging the bottle 1 within the case 2 will now be described with reference to Figures 6 to 13. Referring to Figures 6 and 10, the sheet S initially in the packaging sequence is opened out on its hinges 15 with the walls 11 to 14 laid flat on a horizontal support surface with the open cavities 21 uppermost and the bottom faces 26 of the buffers 24 and 25 resting on it. The bottle 1 is oriented horizontally in register with the bottle-contoured cavity 21 of the base-wall 11, and is lowered down between the flanges 16 to nest conformably within the cavity 21. As illustrated in particular by Figure 7, this seats the neck 6, shoulders 5 and base of the main body of the bottle 1 on the ridges 27 to 29 within the cavity 21 to afford a resilient or spring action in support of the bottle.

As illustrated in Figure 11, the walls 12 and 13 are now folded up on either side of the bottle 1, and the wall 14 is brought over the top. As the walls 12 and 13 are closed onto the bottle 1, as illustrated in Figure 12, the bottle 1 is nested conformably within the cavities 21 of the walls 12 and 13, and the ridges and grooves of the outer surfaces 20 of the flanges 16 of the wall 11 nest in the grooves and ridges respectively, of the outer surfaces 20 of the flanges 17 and 18 of the walls 12 and 13. This ridge-within-groove nesting affords cushioned interlocking of the walls 11 to 13 with one another at each end of the bottle 1. Folding the wall 14 over the bottle 1 as illustrated in

Figures 8 and 12, and closing it onto the bottle 1 as

illustrated in Figures 9 and 13 nests the bottle 1 conformably within the cavity 21 of the wall 14 and establishes ridge- wi thin-groove nesting to give cushioned interlocking of the wall 14 with the walls 12 and 13. Retention of the case 2 locked closed in this way is provided by projections 30 of the wall 14 that are for engagement within slots 31 of a flap 32 hinged to the wall 13.

The case 2 containing the bottle 1 when locked closed, is inserted lengthwise into the carton 3 (or other external packaging) . The bottle 1 in this is protected against external shock by the cushioning buffers 24 and 25 projecting from the outside surfaces B of all four walls 11 to 14 where they are in contact with the inside of the carton 3. It is also protected by the cushioning of the ridge-within-groove interlocking of the flanges 16 to 19 of the walls 11 to 14, and by the springing of the ridges 27 to 29 between the case 2 and the bottle 1. The bellows-like resilience of the flanges 16 to 19 at each end of the bottle 1 function to cushion the bottle 1 longitudinally.

The sheet S when folded round the bottle 1 in the form of the case 2 serves to afford protection to the bottle 1 during transportation and storage, and can be readily re-used for such a service. However, when its service in this respect is no longer required, or re-use is not a practical possibility, it can be usefully and economically used to afford an

efficient and continued degree of shock protection in the provision of a form of wine rack for laying up the bottle 1 together with other, corresponding bottles of wine. In this regard, the sheet S when opened out on its hinges 15 with the walls 11 to 14 laid flat on a horizontal surface, can be used to support four bottles laid horizontally side by side for storage. Figure 14 shows four bottles 41 (each corresponding to bottle 1 described above) being laid down in this way, for nested support horizontally and side by side on the four wall- sections 42 of a thermoformed sheet-moulding 43 identical to the sheet S described above. A second, identical packaging- case moulding 44 is shown in Figure 15 in the process of being placed on the four bottles 41 for support on the bottles 41 by the buffers 45 of the moulding 44. The cylindrically-concave bottoms 46 of the buffers 45 (corresponding to the bottoms 26 of the buffers 24 and 25 of the sheet S) provide good

conformal surface-contact with the bottles 41 to enhance the location and alignment of the moulding 44 with moulding 43.

A further four bottles 47 may now be stored on the moulding 44 in a similar way to the bottles 41 on the moulding 43, and indeed as illustrated in Figure 16, a further moulding 48 identical to each of the mouldings 43 and 44 may be used to add a further layer of bottles 49 to the stack. Still further layers of bottles may be added in the same way for as long as the stack remains stable.
