专利说明:
[0001] This application is a continuation of application number PCT/IB99/01372 filed on Aug. 2, 1999. [0001] BACKGROUND OF THE INVENTION
[0002] The present invention relates to a cardboard pallet-type container/exhibitor. [0002]
[0003] In recent times, a type of large container made of a single material is becoming increasingly widespread in packaging technology due to ecological reasons and package-recycling laws. [0003]
[0004] This is in fact the only way to reduce the relative amount of material assigned to packaging and at the same time allow complete recycling of the package without having to separate parts made of different materials. [0004]
[0005] A second strongly felt requirement, particularly in the field of packaging meant for products to be distributed in shops and supermarkets, is that the container must be able to also act as an exhibitor, so that the customer can directly take the packages contained therein in the required amount. [0005] SUMMARY OF THE INVENTION
[0006] The aim of the present invention is to provide a container which can be manufactured by using a single material and can be obtained with a very simple operation. [0006]
[0007] An important object is to provide a container which can be placed directly in the point of sale so that it constitutes the exhibitor for the products contained therein. [0007]
[0008] Another object of the present invention is to provide a large container which can be easily filled in an orderly fashion even without necessarily resorting to automatic loading systems. [0008]
[0009] A further important object of the present invention is to provide a container which can be easily and completely filled with products intended for sale and then emptied manually or through automatic equipment and allows easier access. [0009]
[0010] Another object of the present invention is to provide a container/exhibitor at low-cost. [0010]
[0011] A container/exhibitor made in folded cardboard is known from the document GB-A-2 027 413. [0011]
[0012] The aim and the objects of the present invention and others which will become apparent hereinafter are achieved instead by a container/exhibitor having the features of claim [0012] 1. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Further characteristics and advantages of the present invention will become better apparent from the description of a preferred embodiment thereof, illustrated only by way of non-limitative example in the accompanying drawings, wherein: [0013]
[0014] FIG. 1 is a top view of a cardboard sheet from which a container/exhibitor according to the present invention is to be obtained; [0014]
[0015] FIG. 2 is a perspective view of the container/exhibitor according to the invention, freshly obtained from the cardboard sheet of FIG. 1; [0015]
[0016] FIG. 3 is a view of the container/exhibitor of FIG. 2, divided along the die-cut lines into a base semi-container and a top semi-container; [0016]

[0020] FIG. 7 is an exploded view of a detail of FIG. 6. [0020] DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] With reference to the above figures, a container/exhibitor according to the present invention is generally designated by the reference numeral [0021] 10 and is obtained starting from a sheet 11 made of corrugated cardboard.
[0022] Said sheet [0022] 11 is substantially rectangular and has first mutually opposite sides 12 and second longer mutually opposite sides 13.
[0023] Proximate to one of said second sides [0023] 13, which forms the upper part of the container/exhibitor 10 as will become apparent hereinafter, first parallel transverse slots 14 are provided at regular intervals.
[0024] At the other second side [0024] 13, which forms the lower part of the container/exhibitor 10, second slots 15 are provided which are also parallel and define a central portion 16 and first and second portions 17 and 18 to the sides of said central portion.
[0025] Tabs [0025] 19 are formed by cutting in said central portion 16, and each tab has a free end 36 which is wider than the rest.
[0026] Shaped holes [0026] 37, associated with a retention tab 38, are formed in said first portions 17, each of which is arranged to one side of the central portion 16.
[0027] Said central portion [0027] 16 constitutes the bottom 20 of the container/exhibitor, since it is adapted to be conveniently assembled, by means of suitable interlocks between the edges formed by said second slots 15, to the second portions 18.
[0028] First pressed lines [0028] 21 which constitute guiding lines for folding are formed in said cardboard sheet 11 along lines which are parallel to said first and second mutually opposite sides 12 and 13.
[0029] In particular, said first pressed lines [0029] 21 are spaced from the corresponding second sides 13 by a distance which corresponds to the extension of the respective first and second slots 14 and 15.
[0030] It is observed that second mutually parallel pressed lines [0030] 39 are formed in said first portions 17, as will become apparent hereinafter.
[0031] Moreover, through cuts [0031] 22 are provided in the sheet 11 and form, as a whole, a discontinuous straight path so as to constitute guides for tearing.
[0032] Said through cuts [0032] 22 are obtained in the sheet 11 by die-cutting, preferably simultaneously with said first and second slots 14 and 15.
[0033] In particular, third transverse slots [0033] 23 are formed in the cardboard sheet 11 proximate to the regions where said through cuts 22 change direction, as will become apparent hereinafter.
[0034] Starting from the cardboard sheet [0034] 11 and performing the appropriate folds according to the corresponding folding guides formed by said first pressed lines 21, and after performing the appropriate interlocks between the edges formed by said first and second slots 14 and 15, an internally hollow parallelepiped is obtained from which said container/exhibitor 10 is obtained by following said tearing guides formed by the through cuts 22.
[0035] In particular, it is necessary to produce, on the first portions [0035] 17, the folds formed by said second pressed lines 39 so as to give each portion a U-like cross-section whose wings 40 diverge outward.
[0036] In this manner, each one of said first portions [0036] 17 constitutes a first component for supporting legs, generally designated by the reference numeral 28, of the container/exhibitor 10.
[0037] Said container/exhibitor [0037] 10 comprises a base semi-container, designated by the reference numeral 24, which is constituted by said flat bottom 20, provided with the legs 28 as better described hereinafter, from which there protrude a low front wall 25, a quite high rear wall 26, and mutually opposite side walls 27 which are delimited in an upward region along the diagonals.
[0038] The upper profile of the front wall [0038] 25, of the rear wall 26 and of the side walls 27 is formed by the path of said through cuts 22.
[0039] In this constructive configuration, each one of said supporting legs [0039] 28 is obtained by inserting in the corresponding first U-shaped portion 17 a second component 41 known per se, for example of the type disclosed in EPA No. 96938186.2 of Nov. 12, 1996.
[0040] Thereafter, the assembly of the legs [0040] 28 is completed by inserting each one of the tabs 19 in the wider part of the corresponding shaped hole 37, in which it is retained by interlocking, due to the weight of the container/exhibitor 10 and of the items contained therein, also in association with the retaining tab 38 which retains the corresponding free end 36.
[0041] Said container/exhibitor [0041] 10 further comprises a top semi-container 29 whose structure is complementary to the base semi-container 24 and has a top surface 30 from which there extend a front wall 31, whose height substantially corresponds to the height of the rear wall 26 of the base semi-container 24, a rear wall 32 of reduced height, and mutually opposite side walls 33, whose profiles follow the profiles of the corresponding side walls 27 of the base semi-container 24.
[0042] Said top semi-container [0042] 29 is suitable to be fitted over said base semi-container 24 thanks to the presence of said third transverse slots 23, which allow a suitable widening of the front wall 31 and of the side walls 33 of the top semi-container 29 with respect to the corresponding walls 25 and 27 of the base semi-container 24.
[0043] The coupling of said top semi-container [0043] 29 on the base semi-container 24 is possible by overlapping a portion that corresponds to the distance, schematically designated by the reference numeral 34, which lies in FIG. 2 between the profile of the rear wall 26 of the base semi-container 24, formed by the through cuts 22, and the corresponding first pressed portion 21 that forms the fold between the top surface 30 and the rear wall 32 of the top semi-container 29.
[0044] As regards the structure of the container/exhibitor [0044] 10, access to its interior is facilitated thanks to the low front wall 25 of the base semi-container 24, so that the insertion of the products, schematically designated by the reference numeral 35, and their subsequent removal can be performed easily.
[0045] In practice it has been found that the present invention has achieved its aim and all its objects. [0045]
[0046] It is in fact interesting to notice that the container/exhibitor [0046] 10 obtained with the present invention is made of a single fully recyclable material.
[0047] It is also important to note the fact that said container/exhibitor [0047] 10 can be arranged directly in the point of sale, since it acts as an exhibitor for the products 35, of the individually-packaged type, contained therein.
[0048] Accordingly, a purchaser can easily remove, in the chosen amount, the products that he intends to acquire. [0048]
[0049] A particular advantage is ensured with the present invention in that a container has been provided which allows easy removal or insertion of items therein or therefrom even in the vicinity of the bottom, since access to its interior is facilitated. [0049]
[0050] Another considerable advantage is clearly linked to the fact that the described container/exhibitor can be manufactured with machines and equipment which are conventional in the field, at a low cost and by using a single recyclable material, preferably cardboard, by assembling the parts by interlock couplings without using adhesives. [0050]
[0051] The present invention is susceptible of numerous modifications and variations, all of which are within the scope of the claims. [0051]
[0052] The materials used, so long as they are compatible with the contingent use, as well as the dimensions, may be any according to requirements. [0052]
[0053] All the details may also be replaced with other technically equivalent elements. [0053]
[0054] The disclosures in Italian Patent Application No. PD98A000192 from which this application claims priority are incorporated herein by reference. [0054]
