Definitions
- the present invention relates to a carton (or tray) for accommodating foodstuff, for example fish or meat, and more particularly to a carton formed from one or more blanks of paperboard or other suitable foldable sheet material.
- Tray structures for meat are commonly formed from plastics material, for example polystyrene.
- US 3 156 402 shows a food products support tray including two layers in which the liquid is stored. The liquid passes through openings and is held between the layers. It is apparent that handling of the tray will push liquid back through the openings. Further, if the tray is stored in an upright position, the liquid will collect along the edges and at the corners.
- the present invention and its preferred embodiments seek to overcome or at least mitigate the problems of the prior art.
- a first aspect of the invention provides a tray for holding foodstuff or the like, which tray is formed from foldable material, the tray including a base and opposed end and side walls hingedly connected to the base wherein one or more of the side or end walls is a multi-ply structure.
- the foldable material has first and second opposed sides and the inside and outside surfaces of said side or end wall expose the first and second sides of the foldable material respectively.
- the tray is of a one piece construction formed from a single blank of foldable material.
- the multi-ply structure forming said side or end wall comprises a first panel hingedly connected to the base panel along its lower edge, and second and third juxtaposed panels disposed along the inside surface of the first panel, the first and second panels are hingedly connected together along their common upper edge and the second and third panels are hingedly connected together along their common lower edge.
- the foldable material has been processed to provide a first side with a desired property suitable for the first side to directly contact the article to be received in the tray.
- the first side is coated with an impermeable layer.
- the impermeable layer is formed from any one of a plastics film, a waxed layer or a co-polymer, for example carboxylated styrene or butadiene.
- a second aspect of the invention provides a blank for forming a tray for holding foodstuff or the like, which blank is formed from foldable material, the blank including a base panel and opposed end and side wall panels hingedly connected to the base panel wherein one or more of the side or end wall panels is adapted to form a multi-ply structure in a set up tray.
- the foldable material of the blank has first and second opposed sides and the inside and outside surfaces of said multi-ply structure expose the first and second sides of the foldable material respectively.
- the multi-ply structure forming said side or end wall comprises a first panel hingedly connected to the base panel along its lower edge in a set up tray, and second and third juxtaposed panels disposed along the inside surface of the of the first panel, the first and second panels may be hingedly connected together along their common upper edge and the second and third panels may be hingedly connected together along their common lower edge.
- the foldable material has been processed to provide a first side with a desired property suitable for the first side to directly contact the article to be received in the tray. More preferably, the first side is coated with an impermeable layer.
- a third aspect provides a method of forming the multiply structure in a tray formed from a blank according to a second aspect of the invention wherein the second and third panels are folded inwardly with respect to the first panel so that the second panel is in face contacting arrangement with the first panel and the third panel is then folded outwardly with respect to the second panel to place the second and third folded panels in face contacting relationship to be secured thereto, thereby revealing the first surface of the foldable material.
- FIG. 1 there is shown a blank 10 for forming a collapsible tray or carton made from one or more blanks of paperboard or similar foldable sheet material.
- the blank 10 comprises first end wall panel 12, base panel 14, and second end wall panel 16 hingedly connected together in series along fold lines 18, 20 respectively.
- each side wall 22, 24 is multiply which, in this embodiment is formed by one or more panels.
- a triple-ply is provided in part by outer side wall panels 26, 38, side support panels 28, 40 hingedly connected to outer side wall panels 26 and 38 by fold lines 34, 46 respectively.
- side support panels 28, 40 substantially correspond to the height and/or shape of outer side panels 26, 38 respectively.
- inner side wall panels 30, 42 may substantially correspond to the height and/or shape of outer side wall panels 26, 38.
- Suitable securing means for connecting the end and side panels together is provided.
- the web structure comprises web panel 56a hingedly connected to outer side wall panel 38 and end wall panel 12 along fold lines 52a and 54a respectively.
- Each end wall panel 12, 16 may further comprise one or more flaps, for example flap 60 hingedly connected to an end wall panel 12 along fold line 62 and flap 64 hingedly connected to end wall panel 16 along fold line 66.
- the end wall flaps are adapted to provide additional "ad-panels" and to support the structure placed over the tray.
- side support panels 28 and 40 and inner side wall panels 30, 42 are folded inwardly about fold line 34 and 46 and into face contacting relationship with outer side wall panels 26 and 38 respectively and base panel 14, and is secured thereto by glue G or other suitable securing means known in the art. Thereafter, inner side wall panels 30 and 42 are folded outwardly about fold lines 36 and 48 and into face contacting relationship with side support panels 28, 40 and are secured thereto by glue G or other suitable securing means known in the art, as shown in Figure 3.
- Figures 2 and 3 illustrate one example of the position of glue G applied to the blank prior to folding the carton.
- the glue is in the form of "hot melt” so to provide a seal between the base and the respective support walls to prevent migration of the liquid.
- the carton is in a flat collapsed form to be supplied to the user so that it can be erected to provide a tray.
- the carton of the present invention can be formed by a series of sequential folding and gluing operations, which can be formed in a straight line machine so that the carton is not required to be rotated or inverted to complete its construction.
- the folding process is not limited to that described below and can be altered according to the particular manufacturing requirements.
- the carton (or tray) is formed by folding outer side wall panels 26, 38 inwardly about fold lines 32, 44 respectively to define the side walls 22, 24 as shown in Figure 4.
- the end walls are formed by folding the end wall panels 12, 16 about fold lines 18, 20.
- the securing flaps 50a-d are secured to the end wall panels 12, 16 by glue or other suitable means to retain the tray in a set up condition shown in Figure 4.
- the web structures are formed at the same time to seal the comers by folding web panels 56 about fold lines 52 and 54.
- a tray 80 for holding foodstuff or the like which tray is formed from paperboard or like foldable sheet material and can be erected from a flat collapsed condition into a position of use and includes a multiply structure along one or more walls of the tray, for example the side walls 22, 24 is shown in Figure 4.
- the foldable material forming the blank has two surfaces, an inner surface I, and an outer surface O. Each surface may be provided with a different coating or layer.
- the inner surface I is revealed on all walls within the tray.
- the panels providing an internal surface I for example the base 14, side walls 22, 24 and end walls 12, 16 are coated with an impermeable layer.
- the impermeable layer is a co-polymer for example carboxylated styrene or butadiene or it could be a plastics film or a waxed layer.
- the cross section of the blank of this embodiment would comprise in series from the inner surface: co polymer, printed matter (if desired), and board.
- the multiply embodiment hereinbefore described provides a structure that is strengthened to retain foodstuff.
- the use of paperboard material provides an "environmentally friendly" alternative to trays formed from plastics material and the tray can include printed matter for marketing purposes.
- the arrangement of the panels for the tray in the embodiment described above allows printed matter to be placed on the external side and end walls of the tray.
- 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.
- the present invention and its preferred embodiment relates to a tray which is shaped to provide satisfactory rigidity to hold items such as meat or fish securely but with a degree of flexibility.
- the shape of the blank minimises the amount of paperboard required for the carton.
- the items can be applied to the carrier by hand or automatic machinery. It is anticipated the invention can be applied to a variety of carton or tray types and not limited to those of the flat tubular sort, for example the flat tubular structure could be replaced by a structure with longer sides and end panels to receive larger cuts of meat.
