BRIEF DESCRIPTION OF THE DRAWINGS One embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings 20 in which: FIGURE 1 is a plan view of a template for forming a cardboard box in accordance with a preferred embodiment of the invention; FIGURE 2 is a bottom plan view of the template shown in Figure 1;
FIGURE 3 illustrates an isometric view of the cardboard sheet formed from the template illustrated in FIG. 1 shown during folding; and FIGURE 4 is a cross-sectional view "-X of the carton formed from a plan 'as shown in Figure 3. Referring first to Figure 1, a template 10 is shown for forming a collapsible tray or cardboard made from one or more templates or similar folding sheet material The plant 10 comprises the first side panel 12, panel 14 of b the second side panel 16 connected hinged in series as along lines 18, 20 abatement respectively. it further comprises panels 22, 24 opposite end pivotally connected to opposite side edges of panel 14 of outer base along the lines 28, 30 chilling respectively. When the tray is in an installed condition, the base panel 14 includes a double-lined area, which in this embodiment, is formed from one or more panels, preferably, the double-lined area extends within or in each of the panels. 12, 16, 22, 24 side or end. In this embodiment, the double-lined area is provided by lateral support panels 32, 34 foldably connected to the side panels 12 and 16 by the fold lines 36, 38 respectively. It further comprises end support panels 40, 42 foldably connected to the end panels 22, 24 along the fold lines 44, 46. Optionally, the panels 5 32, 34 include side support lines 46, 50 respectively spaced and parallel to folding lines 18, 20 respectively to define abatement portions 49 and 51. Each portion 49 and 51 substantially corresponds to the height and / or configuration of the lateral panels 12, jA 10 16 respectively. Likewise, the end support panels 40, 42 may include respectively spaced down lines 52, 54 and parallel to the downlines 36, 38 to define the portions 53, 55, which correspond substantially to the height and / or
configuration of the end panels 22, 24. Appropriate security means are provided to connect the side and end panels together. In this embodiment, it comprises a pair of opposingly arranged safety fins 56, 58 extending from the ends
opposed to the side support panels 32 and 34 and connected thereto along the fold lines 60 and 62 respectively. As illustrated in Figure 1, the abatement lines 18, 20 and 28, 30 are preferably defined in part
by a series of interrupted cuts 19 for easy handling of the adjacent panels. Edges can be configured and shaped to contain the elimination of excess food liquid. • Returning to the construction of the tray 5 illustrated in Figures 2 and 3, the lateral support panels 32 and 34 are maintained around the folding lines 36 and 38 respectively and inside the face making contact with the relationship with lateral panels 12 and 16 respectively, and secured to the base panel 14 by
glue or other suitable security means 64. Likewise, the end support panels 42 and 44 are folded around the fold lines 44 and 46 and into the face contacting the relationship with the bottom surface of the end panels 22, 24 and the portions thereof.
outside of the side and end panels are secured to the base panel by glue or other suitable security means 64. Figure 2 illustrates an example of the position of glue applied to the bottom of the template before folding the carton. Preferably,
The glue is in the form of "heat fusion" to provide a seal between the base and the respective support walls to prevent migration of the liquid, described in more detail below. In this way, the cardboard box is in a flat collapsed form that is administered to the
user so that he can get up to provide a tray. It is envisioned that the carton of the present invention can be formed by a series of sequential bending and gluing operations, which can be formed in a continuous production machine so that the carton is not required to be made turn or reverse to complete its construction. The bending process is not the one described below and may be altered in accordance with the particular manufacturing requirements. The carton (or tray) is formed by d 'Aar the side panels 12, 16 inward around the fold lines 18, 20 respectively to define the side walls, as shown in Figure 3. The end walls they are formed by folding the end panels 22, 24 around the folding lines 28, 30. Finally, the safety flaps 56, 58, are secured -. the end panels 22, 24 by glue or other suitable means for retaining the tray in a prepared position and for sealing the ends of the double lined zones 82 as illustrated in Figure 3. Therefore, the food product is loaded inside. of the tray from above and the flexible film can be applied to the tray to seal the package. In this way, a tray 80 for containing similar food products, the tray is formed from cardboard or similar foldable sheet material and can be lifted from a flat collapsed condition within a use position that includes a double lined area 82 around of the lateral walls 12, 16, 22, 24 and
• end and parts of the base panel 14 to provide a space 66, shown in Figures 3 and 4. In use, the excess liquid (or exudate) 76 of the food product 62 is retained in the tray because the base It is waterproof. Preferably, the panels that provide an internal surface, for example the base 14,
The end and side walls 12, 16, 22, 24 are coated with an impermeable layer 72. In the embodiment described above, the impermeable layer 72 is a copolymer, for example styrene or carboxylated butadiene. As shown in Figure 4, the cross section of the support panels
of this modality include in series from the inner surface, copolymer, printed material (if desired), white coating and cardboard. When the tray is stacked in a straight position, for example on a supermarket shelf, the liquid in
The excess tends to collect at the edges and at the corners. In order to remove excess fluid from the tray, a space 76 is provided by the double-lined zone 82, shown in more detail in the Figure. The resulting space 66 is in between the side panels 12, 16 (and of
End) and support panels 32, 34 and 40, 42 that can be used to receive the excess blood liquid (i.e. blood or water) present in the tray by means of the fluid communication between the inner surface of the tray. base and space. It is envisioned that the or each space 66 can be adapted to receive suitable absorbent material, for example stamping or absorbent bag, preferably during the initial installation process or by application of the absorbent polymer gel, for example polyacrylamide, during the
establishment or glue stages of the construction of the cardboard box. More preferably, the liquid can be absorbed directly by the inner surfaces 49 of the panels that provide the double lined area as shown in Figure 4. In a modality class, the
The effect of capillarity leads to the movement of liquid away from the medium of fluid communication in space. The use of heat fusion glue 64 at the free end of the support panels stops the migration of the liquid. Preferably, the means 68 for giving the fluid communication
are provided by a plurality of cuts or perforations 19 that strike from the inner base panel 22 to assist in the movement of the liquid from the upper surface of the inner base panel 22 within or in each space 66. In these embodiments, where the lines
18, 20, 28, 30 of abatement are defined in parts by
-.---- b- --- ..
a series of cuts 19, the cuts can help in the movement of fluid. Beneficially, the two folds of the embodiment described in the foregoing provide a structure that hardens to retain the food products. The use of cardboard material provides an "environmentally friendly" alternative for trays formed from plastic materials and the tray may include printed material for marketing purposes. The coupling of the panels for the tray in the modality described in the above allows the printed matter that is placed between the inner and outer side and end walls of the tray. It will be recognized as used herein, the directional references such as "upper", "base", "extreme", and "lateral" do not limit the respective panels of such orientation, serve merely to distinguish these panels from each other. Any reference to the articulated connection must be interpreted as a reference necessarily to only one line of individual abatement: it is certainly visualized that the articulated connection can be formed from one or more of one of the following, a notched line, a frangible line or line of abatement, without departing from the scope of the invention. The present invention and its preferred embodiments relate to a tray which is configured to provide satisfactory stiffness to contain items such as meat or fish but is safe with a degree of flexibility. The config < Ion of the template decreases the amount of cardboard prt. gone for the cardboard box. The articles can apply.-.'- to the carrier by hand or automatic machinery. It is anticipated that > The invention can be applied to a variety of carton types or trays and not be limited to those of flat tubular type, for example, the flat tubular structure can be replaced by a structure with larger sides and end panels to receive larger cuts of meats. In addition, the double lined areas can be formed in the inner panels of the carton, without departing from the scope of the invention.
