Description

Container.

Background of the invention

This invention relates to a container that It comprises a base and a lid, each of them manufactured with rigid but foldable laminated material, for example material corrugated. The container is in particular, although not exclusively, suitable for containing such food products such as fresh fish. The invention also relates to a piece of rigid but foldable laminated material, for example of corrugated material, which is capable of forming according to a base of a container, and a packaging procedure.

Conventional fish boxes, that is, the boxes used for packaging, storage and distribution of fish, have been made from wood or material plastic. Such boxes are frequently filled on board longline longliners, and occupy a thickness and a space of Considerable storage when not in use. These boxes of Known fish are relatively expensive and, as such, can be reuse after being cleaned. However, it is difficult to effectively clean such fish boxes in accordance with the hygiene standards required.

It is desirable that the fish boxes have good thermal insulation properties so that the fresh fish stored inside the boxes do not reach get too hot, which makes it difficult to provide thermally insulating fish boxes, made of wood or material plastic, that are relatively cheap.

It has been proposed, through the document US-A-3,937,390 manufacture a box for fish from a corrugated cardboard provided with a impregnation that repels water. In particular, the pieces of this Corrugated impregnated cardboard can be stored aboard a longline, and be armed when fish boxes are needed having walls of simple thickness of corrugated cardboard. Without However, although a box for such fish remedies many of the disadvantages of fish boxes made with wood or With plastic material, the thermal insulation properties of a fish box that has corrugated cardboard walls of Simple thickness, can not be improved.

Summary of the invention

An object of the present invention consists in provide an easily conformable container comprising a base and a top element or lid, which has walls made of rigid laminated material although foldable and having properties of improved thermal insulation. It is also an object of the invention provide a conformable container base from a piece of rigid laminated material although foldable.

In accordance with a first aspect of the present invention, a piece made of laminated material is provided rigid but foldable, according to claim 1.

Documents EP-A-1 122 177, NL-A-1 019 538 and GB-A-614 444, refer to a piece of rigid laminated material although foldable, and a container open at the top formed from said piece, comprising a rectangular bottom, side walls double thickness extending upwards from the bottom, double thick end walls that extend upwards from the aforementioned background, and a reinforcement in each corner of the container.

A starting piece according to the invention, allows you to erect a container base that has double thick side and end walls, thereby improving the thermally insulating properties of the base of container.

Advantageously, the second wall panels side are folded down outside the first side wall panels in the reinforced container, in which case the second end wall honeycombs are also folded out of the first extreme wall panels. However, it is also the second wall panels may be folded down inside the first side wall panels, and in that in case the second end wall panels can be folded towards below through the corresponding first panels of extreme wall

In a more suitable embodiment of the invention For shaping by machine, each extreme flap is configured so that it overlaps with the other extreme flap of the even when the piece is shaped as a container base.

The piece has adhesive means to connect the second end wall panels to the extreme flaps underlying. Typically, the adhesive means comprise a band or double-sided adhesive tape, one side of which adheres to the starting piece, and the other side of which has on it a separable non-adhesive cover. Suitably, the strip or tape Adhesive is provided on the second end wall panels, although, alternatively, it could be provided on the flaps extreme

Suitably, the laminated material of the, or of each, starting piece comprises corrugated material, for example Corrugated cardboard or fiberboard. The material Corrugated, with its cavities, has good properties of thermal insulation and these thermal insulation properties are increase considerably in a shaped container that has walls with more than a simple thickness. In the case of a box for fish, the provision of good thermal insulation results important because if ice is added to its content during the use, for example, while fish is being packaged in a longline, it will defrost less quickly when better the thermal insulation properties of the walls from the fish box. Typically, the laminated material will be endowed, on both sides, with a waterproof coating, such as a plastic material and / or a wax, or with a finish laminate, or it may be impregnated with water repellent material. By way of example, the repellent corrugated laminate material of water is described in the document US-A-5,626,945. The material laminated, at least as regards the starting piece of the element of the upper part of the container, I could have, on its side destined to form the outside of the container, a film cover reflective to reflect heat and light radiation external

With the use of adhesive strips on the starting pieces to keep the containers conformed in their erect condition, the containers can be conformed on site without the use of any machinery of container formation

At least one hole can be arranged in the starting piece to provide a drain in the shaped base.  For example, a hole in the rigid laminate although folding, can have at least one fluid resistant film applied on its periphery, so that it allows the fluid flow through the hole without exposing its periphery to fluid. In particular, a first layer of film resistant to fluid can be applied to one side of the starting piece and a second layer of fluid resistant film can be applied to a second side of the starting piece, having the first and the second layers mutually matching openings that allow the fluid circulate through the hole.

In accordance with another aspect of this invention, a container base formed from  of an initial piece according to the aforementioned first aspect of the present invention

A set of initial pieces according to An additional aspect of the invention comprises a base piece as described above, and a susceptible cover piece of being shaped to be erected in a lid sized for be coupled with the container base, the second panel being extreme wall of each means of extreme wall panel arranged to so that the first end wall panel is spaced in the shaped base so that it fits with an end panel of the lid when the latter is attached to the shaped base to maintain the lid so fitted.

The second end wall panel of the piece initial base and said end panel of the initial piece of lid, may be particularly sized to pass completely one beyond the other by attaching the reinforced lid to the armed base; fitting said end panel of the initial piece of cover below the bottom edge of said second wall panel extreme

The container may be provided with a absorbent pad or a member located inside the base, on top of the bottom panel. The purpose of such an absorbent pad consists of absorbing liquid material, such as ice and blood of stored contents, for example fish, inside the container base when the latter It's in use. This has been planned to prevent the contents stored "float" in the liquid material. Ideally, the absorbent member has been provided to engage intimately in the inside of the container base, that is, it will have substantially the same dimensions as the bottom panel of so that there is a separation or only small spaces between the absorbent pad positioned and the side walls of the container base Typically, the absorbent pad it comprises a fluid impervious top layer and a layer of absorbent bottom, which can themselves be of a thickness of several layers. In particular, the absorbent bottom layer can comprise corrugated cardboard material, or layers, for example 3 to 5, of paper. The pad can incorporate a bactericide or other  substance to control potentially dangerous bacteria, such as salmonella, listeria and legionella.

Agree yet with another aspect of the In the present invention, a packaging method of products, such as food products, comprising assembling a container base from an agreement piece with said first aspect of the present invention, load the container base with the products to be packaged, and close the container base with a top element formed to from said other starting piece. An absorbent member can be positioned in the container base after assembly of the base, and prior to loading the container base with products.

Detailed description of particular embodiments

Figures 1 and 2 show starting pieces for container, generally designated by the numbers of reference 1 and 2, made from rigid laminated material although folding. The starting piece 1 has been planned to be assembled as container base 3, and the starting piece 2 has been provided to form an upper element 4 of a container 5; for example a box of fish, shown in Figures 6 and 7.

A material particularly suitable for starting pieces 1 and 2 that have good properties of thermal insulation, consists of corrugated material, for example corrugated fiberboard or corrugated cardboard, having a couple of separate flat parallel outer liner sheets, and one or more corrugated or corrugated sheets between these liner sheets external. If more than one is provided, for example two, sheets corrugated / corrugated, these are separated by one or more sheets intermediate flat. In Figures 1 and 2 the starting piece is made of corrugated fiber cardboard, comprising lining sheets separate external that have been provided with a coating or Water resistant or water repellent lamination, which form sandwich according to a simple corrugated sheet, extending the channels or corrugated corrugated sheets in the Double-headed arrow A directions. The starting piece 2 It can be equipped with a reflective layer of light and heat on its lower face, that is, the face destined to form the exterior of the shaped container. In parts 1 and 2 of departure fold lines have been represented by means of lines dashed or dashed lines and dots, representing the dashed lines folds up from the plane of the paper, and representing the lines of stripes and folded lines towards down from the plane of the paper. The folding lines are typically bending lines but can be, for example, lines totally or partially perforated. The dotted portions of the starting pieces represent the parts of the piece that have been equipped with adhesive media.

The starting piece 1 comprises a panel 10 rectangular background with a pair of side wall panel media and a pair of end wall panel means attached thereto. Every one of the side wall panel means comprises a first side wall panel 11 (12), foldably connected to side 13 (14) of the bottom panel 10, and a second wall panel (15 (16) side foldably connected to its first wall panel 11 (12) lateral along line 17 (18) of folding. Every second side wall panel 15 (16) has flaps or panels 19 and 20 (21 and 22) ends foldably connected to them around fold lines 23 and 24 (25 and 26), respectively.

Each end wall panel means comprises a first end wall panel 27 (28) foldably connected to one end 29 (30) of the bottom panel, and a second panel 31 (32) of end wall foldably connected to the first panel 27 (28) of extreme wall around a couple of lines 33, 34 (35, 36) of folded closely separated from each other. As can be seen in Figure 1, the second end wall panels 31 and 32 are divided along folding lines 39 and 40, respectively, in portions 37a, 37b, and 38a, 38b, internal and external. Face top (as seen in Figure 1) of the starting piece 1 It has 41 and 42 double-sided self-adhesive strips, provided in portions 37b and 38b, respectively. These Self-adhesive strips 41 and 42 are covered by cover strips releasable non-separable adhesives. Alternatively (it has not been represented), it is possible not to divide the second panels 31 and 32 by means of folding lines 39 and 40, but provide, by the opposite, the self-adhesive strips 41 and 42 on the underside of the initial part 1 (as seen in Figure 1).

In each of the four corners of the panel background, there is a means of reinforcement designated in general with 43-46, respectively, of which only one (the reinforcement means 43) will be described in detail in what follow. The reinforcing means 43 comprises a pair of panels 43a and 43b reinforcement, separated by a line 43c of diagonal folding. He reinforcement panel 43a is foldably attached to the first panel 27 of extreme wall around folding line 43d, and panel 43b of reinforcement is foldably connected to the first wall panel 11 side and end panel 19 along lines 43e and 43f of folded, respectively.

Figures 3 to 6 show several phases of the assembly of a container open at the top, from starting piece 1. Figure 3 shows the initial stages of folding of a side wall panel means and a means of extreme wall panel relative to the bottom panel 10. In the Figure 4 you can see how the second wall panels 15 and 16 side are folded out against the first panels 11 and 12 side wall, respectively, to form side walls with double thickness. From Figures 4 to 6 you can see how the end flaps or panels 19-22 and the media 43-46 reinforcement are folded flat against the outer part of the first respective wall panels 27 and 28 extreme to form at least double thick end walls for the container open at the top. In the final stage of armed of the container opened by the top, the strips of Separable coverage are separated from strips 41 and 42 self-adhesive, outer portions 37b and 38b of panels 31 and 32 end wall are folded back against portions 37a and 38a internal, respectively, of wall panels 131 and 132 extreme, and panels 31, 37 and 32, 38 folded above are pressed against panels 19, 21 and 20, 22 underlying ends to be attached to them using strips 41 and 42 self-adhesive (see Figure 6).

The starting piece 2 comprises a panel 50 rectangular top that has 51 and 52 side panels attached folded to the top panel along sides 53 and 54, respectively, and panels 55 and 56 ends folded together to the upper panel along ends 57 and 58, respectively. The Extreme flaps 59, 60 and 61 are folded together to the opposite ends of panels 55 and 56 ends, respectively. The double-sided adhesive tape is attached to lateral regions opposite of the starting piece 2, to provide strips 63 and 64 parallel adhesives on side panels 51 and 52, respectively, and 65-68 parallel adhesive strips in the 59-62 extreme flaps, respectively. To the As with the starting piece 1, the outer adhesive layer is covered by a strip of suitable separable coverage.

In order to close the container 3 opened by the upper part, an upper element 4 is formed from the starting piece 2. Suitably, the upper element is not pre-formed but, on the contrary, it position with the top panel 50 over the top of the container open at the top. The end panels are folded then down against the extreme walls from the container, the cover strip is removed from the strips 65-67 adhesives, and flaps 59-62 fold against, and adhere to, the side walls of the container. Finally, the separable coverage strips are removed from adhesive strips 63 and 64 and panels 51 and 52 sides are folded back down, and attached to, the side walls of the container (see Figure 7).

Figures 8 and 9 show a first and a second pieces of departure, respectively. The numbers of reference of Figures 8 and 9 correspond to those of Figures 1 to 7, but with the addition of 100.

Figure 8 shows a first piece 101 starting alternative, which is widely similar to the first starting piece 1 of Figure 1. The main difference is in which the end flaps 119 to 122 of the first piece 101 of alternative heading, are elongated in the longitudinal direction of The starting piece. This means that when the piece is assembled to form a container, the flaps 119 and 121 ends are overlap, and flaps 120 and 122 overlap. This provides additional resistance to the ends of the container, and helps avoid buckling of the ends when the full container is pulled in longitudinal direction.

Figure 9 shows a second piece 102 of alternative heading comprising a rectangular top panel 150 which has 151 and 152 side panels folded together to the panel upper along sides 153 and 154, respectively, and panels 155 and 156 ends folded together to the upper panel along ends 157 and 158, respectively. The flaps 159, 160 and 161, 162 are foldably attached to opposite ends of panels 151 and 152, respectively. Adhesive tape double side is adhered to opposite side regions of the piece 102 for starting to provide an adhesive strip 163 that runs along side panel 151 and flaps 159, 161 ends, and a parallel adhesive strip 164 that runs along the panel 152 side and flaps 160, 162. As with part 101 Starting, the outer adhesive layer is covered by means of a strip of adequate separable coverage.

In order to close the open container by the upper part, assembled from the starting piece 102, is it forms a superior element from the starting piece 102. OR either the upper element may be pre-assembled or Well, the starting piece 102 can be positioned with the panel 150 top over the top of the container opened by the upper part. The panels 155, 156 ends are then folded down, against the extreme walls of the container. The strip of Cover is removed from the 163, 164 adhesive strips, and panels 151, 152 sides fold down against, and adhere to, the side walls of the container. The flaps 159-162 extremes are then folded against, and adhered to, panels 155, 156.

In the closed container according to the invention, the side and end walls provided by the container opened by the upper part, and by the lid or upper element, each have at least three thicknesses of starting sheet material, for Provide good thermal insulation to any product contained in the container. Typically, during use, the container opened by the upper part will be used for packaging suitable products, such as fresh fish and also ice optionally, and may be closed by the upper part assembled from the starting part 2 or 102. If used in situ , on a longline or similar, pieces 1 and 2, or 101 and 102, starting, can be kept in their flat, unarmed condition, until a container needs to be used. The storage space is therefore not occupied by armed, empty containers.

A particular advantage of the open container by the superior armed, is that the construction has been intended to protect those channels of the laminated material corrugated that have open ends with respect to contact / exposure to ice or water when the packing. Normally, during packaging, ice is thrown on the top of the contents packed in a way capricious However, as can be seen in the drawings, there is a minimum exposure of the edge groove with the internal and external protective layers throughout the design. In particular none of the upper edges of the walls ascending has the edge groove exposed.

Advantageously, an absorbent member 70 (see Figure 10) can be positioned at the bottom of the container open at the top armed, before the container is Fill with products. The absorbent member 70 has a fluid proofing, for example, a top layer 71, of plastic, and an absorbent bottom layer 72 comprising typically a number, for example 3 to 5, of layers of paper, a or more layers of corrugated cardboard or other absorbent material. He purpose of the absorbent member 70 is to provide a absorbent pad at the bottom of the container to absorb liquids, for example molten ice and product blood stored such as fish, to prevent the product stored "swim" in the fluid. Ideally, the absorbent member 70 is dimensioned so that it is similar to the bottom of the container, with the so that there is no space, or only small spaces, between the edge of the absorbent pad and the walls of the container. The fluid-impermeable upper layer 71 provides a virtually dry surface, or barrier on which the product to be packaged. The absorbent member or "pad" can incorporate a bactericide to control possible dangerous bacteria, such as salmonella, listeria and legionella. The bactericide or other substance, can be impregnated in the paper or incorporated in the glue or other absorbent pad material.

Figure 11 shows another first piece 201 of alternative heading, which is largely similar to piece 101 starting point shown in Figure 8. However, the seconds end wall panels 231, 232 of the starting piece of the Figure 11 are wider than the corresponding second panels end wall of Figure 8. Additionally, they are provided tabs 280, 281 in the center of the free edges of the second end wall panels 231, 232, respectively. When the container base is upright, the tongue 280 is stuck by below the lower overlapping edges of the flaps 220 and 222, and tongue 281 sticks below the bottom edges overlapping of the flaps 219 and 221 ends, to fix the Second penalties of extreme wall in place.

Figure 12 shows a starting piece 202 additional for alternative cover. This one has corresponding panels  with those of the starting piece 102 for lid of Figure 9 (and that have been designated by the same reference numbers to that has been added 100). However, in the starting sheet for lid of Figure 12, triangular corner pieces 285 connect 255, 256 end panels with flaps 259-262 extremes. Also, the flaps 259-262 extremes are elongated. The flaps 290, 291 extremes have been provided in the second panels 292, 293 of extreme wall of the starting piece for lid, which are connected by bending lines with the first panels 255, 256 extreme wall, respectively.

During the assembly of a cover from the starting piece 202 for lid, wall panels 251, 252 side and end wall panels 255, 256, are folded towards down from the upper panel 250. The flaps 259-262 ends and 285 triangular pieces, are folded to create reinforced corners, thereby avoiding leaks even when the closed container is inverted. Unlike that in the case of extreme 219-222 flaps of the base, which folds out of the first wall panels extreme thereof, the flaps 259-262 extreme of the starting piece for lid folds inside the first panels 255, 256 of extreme wall. The second panels 292, 293 of extreme wall are folded inwards and towards above on the 259-262 extreme flaps, and the tabs 290, 291 are glued on, and behind, the flaps extreme

When attaching an armed cover from the piece 202 starting, to an armed base from the starting piece, second base wall panels 231, 232 press against the second end wall panels 292, 293 of the lid, and They provide a tight coupling.

Figures 13 and 14 show starting pieces for base and cover that have an increased fit between the lid and base when armed. In this embodiment of the invention, the second end wall panels 331, 332 of the base and second panels 392, 393 end wall of the lid, they are narrower than the corresponding panels shown in the Figures 11 and 12. Also, the flaps 319-322 base ends and outermost parts of the flaps 359-362 ends of the lid, are narrower, than so that the tabs 380, 381, 390, 391, can still be glued behind them, respectively.

A cover formed from the piece of heading of Figure 4, has its second panels 392, 393 of extreme wall extending upwards inside the first panels 355, 356 ends on one part only, by example about half the height of it. So similar, a base formed from the starting piece of the Figure 13 has its second end wall panels 331, 332 extending upwards through the inside of the first panels 355, 356 ends on one part only, the height of the same, preferably around the same extent as the part of the first panels 355, 356 cap ends that are not covered by the second panels 331, 332 of extreme wall of top. Thus, when the lid is attached to the starting piece, there is a positive consolidation between the second panels 331, 332 extreme wall of the base and the second panels 392, 393 of extreme wall of the lid, so that the former move towards the space formed above the last ones, and vice versa.

In versions that can be assembled with machines (no represented) of parts 201, 202, 301 and 302 of departure, the 280, 281, 290, 291, 380, 381, 390, 391 extreme tabs have been omitted, and the fixing of the second end wall panels is I could only get with adhesive means.

It is often desirable to allow fluid drainage, such as water resulting from molten ice, packed around the product in the container. To this end, it They can provide drainage holes. For example, as per shown in Figure 15, holes 95 of drainage in the fold between the bottom panel and the walls (in this case, the end walls) of the base of the container. Simply provide a hole in the laminate corrugated, may be unacceptable due to possible entry of fluid in the channels of the material. That way, they apply to water resistant film holes, preferably in shape of patches 96 adhesives having drainage openings 97. Is according shown in Figure 16, patches 96 are applied to both sides of the starting piece and prevent the fluid from reaching the edges of the holes 95 that in your case could be exposed.

If desired, pieces of additional heading flat, rectangular, thermally insulating (not shown) at the bottom of the armed container opened by the upper part, before the latter is filled with products, and on top of the container filled just before the lid is attached to the container. Thus, additional thermally insulating layers can be provided on the bottom and on top of the container.

The provision of a reflective layer of light and of heat, at least on the surface of part 2, 102, 202 or 302 starting, intended to form the outer part of the lid or top element, improves thermal insulation properties of the upper element.

Although corrugated fiber carton is currently the preferred material for the wrap, it could be make, for example, with corrugated polypropylene copolymer of double layer or other rigid but foldable laminated material that it may or may not be corrugated or ribbed, and that it may comprise plastic materials, for example EVA (ethylene vinyl acetate), EPS (polyform) or PVC.

In accordance with another aspect of the invention, provides an absorbent pad for inclusion in a fish box or a box for another product, and that incorporates a bactericide.
