Abstract

A blank for an unlined container having a substantially rectangular bottom (1), upwardly diverging sides (2, 3, 6, 7) and round the entire upper edge an obliquely downwards directed edge flange (20) includes portions (12, 13, 10a) of the short sides (6, 7) and of joining pieces (10) which have had their thickness reduced by grinding or milling so that a tongue defined by overlapping portions of the blank at each end of the container is reduced in thickness. Preferably the blank is made of a relatively stiff cardboard material, which at least at the intended inner side of the container bowl has a laminated or extruded surface layer of plastic, metal foil or a combination thereof. The grinding or milling of the material is made from the cardboard side to a level at or close to the surface layer material of plastic, metal or a plastic-metal combination. <IMAGE>

Description

SPECIFICATION Blank for an unlined container bowl The present invention relates to a blank for an unlined cardboard container bowl of the type which has a substantially rectangular bottom, upwardly diverging sides and round the entire upper edge an obliquely downwards directed edge flange which extends uninterrupted and unbroken around the entire upper edge and which provides a joint edge to edge substantially at the middle of two opposite straight sides, and in which the container blank in folded and erected state has an upwardly directed tongue which is folded outwards-downwards over the edge flange and is fold in at the rear side of the edge flange thereby providing a locking of the edge flange joint.
Lined cardboard container bowls of this type are previously known, in which such upwardly extending tongue is formed by the thin and easily foldable lining material which is fold round the edge flange thereby providing the said locking of the edge flange joint. In unlined containers it is necessary that the cardboard material itself provides the upwardly projecting tongue for providing the edge flange joint. Often a cardboard container bowl of this type must be made of a relatively strong cardboard material so that the container gets a sufficient stability, and the projecting tongue, which for folding reasons is fold by at least three layers of cardboard material therefore becomes thick and adjacent the edge flange joint gives the container a rough and heavy appearance.Also there may be difficulties in folding the thick cardboard tongue formed by several layers of cardboard around the edge flange and there is a risk that the edge flange is damaged during such operation. When packing goods of the type which must be packed hermetically, for instance food stuffs like butter and margarine etc.
a thin foil is applied over the packed goods and against the upper edge of the container, but at the said thick cardboard tongue a heavy step is obtained between the upper edge of the container and the upper most surface of the tongue which makes it difficult to get a good sealing between the sealing foil and the upper edge of the container.
Therefore an object of the invention is to solve the problem to provide a blank for an unlined container of the aforementioned type which blank solves the said problem of providing a thin, flexible and easily foldable tongue providing an end and a locking of the edge flange joints.
What is characterizing from the invention will be evident from the following detailed specification and from the accompanying drawings.
In the drawings figure 1 shows a blank for a container to the invention, figure 2 is a partly ready container bowl made from the blank according to figure 1, and figure 3 shows a partial cross section in enlarged scale according to line Ill-Ill of figure 2.
The container blank according to the invention is made of such stiff and heavy material that a container made from the said blank can be used for packing of different solid, liquid and paste formed products and any other products without the use of a separate lining or an outer casing. As examples of suitable materials of the blank can be mentioned cardboard, fiber board, different types of plastic materials etc. A specially preferred material is cardboard which at least at one side is laminated with a thin and easily foldable plastic material or a combination of aluminium and synthetic resin. Alternatively the material of the container blank may be cardboard which is lackered or treated in a similar way at least on one side of the blank.For packing of liquid or paste formed products it is usually a need that the container bowl is liquid tight and this is especially important when packing of fat products like butter or margarine since the fat otherwise has a tendency to penetrate into the non-sealing material and may even in some cases extract harmful components therefrom.
For the sake of simplicity the invention will in the following be described only with reference to a blank of cardboard material which at one side thereof is laminated with a thin and easily foldable and liquid tight plastic material.
The illustrated blank for an unlined container bowl is formed as an integral unit without slots or any other cuts and which is punched from a plastic laminated cardboard material and which can only by being creased and folded be formed to a container bowl.
The blank illustrated in figure 1 comprises a container bottom 1 of rectangular form and two opposite sides 2, 3 which are integral with the bottom and which are longer than the edge 4 and 5 respectively of the bottom with which they are coherent, and the blank further comprises two opposite sides 6, 7 which are at most the same long as the edge 8, 9 of the bottom with which they are coherent. Between each pair of a long side 2, 3 and a short side 6, 7 there is a substantially triangular joining piece 10 which makes it possible to provide a sealed container bowl. When erecting the container the joining pieces 10 are intended to be fold in between the belonging sides 2, 3, 6, 7 and for providing a sealed container the joining pieces 10 are with a portion 1 Oa extended some distance outside the connection point 11 of the adjacent long side 2, 3.
The long sides 2 and 3 preferably should be so much longer than the corresponding edges 4, 5 of the container bottom that the sides of an erected container bowl meet each other edge to edge thereby providing each other to an entire container side.
In order that the tongue intended to lock the edge flange should be sufficiently thin and foldable the cardboard material of the narrow sides 6, 7 and the adjacent joining pieces 10 are ground or milled outside an imaginary line between the connection points 11 of the joining pieces 10 at the long sides 2, 3. In the drawings the said ground or milled portions are given the reference Nos. 12 and 13. The milling is made from the cardboard side and such distance through the cardboard material towards the side having the plastic laminate, the aluminum foil or similar that the material becomes sufficiently thin and foldable for making it possible to simply handle the tongue and for applying a protection foil under sealed conditions round the upper edge of the container.At the same time the milled portions 12, 13 should be sufficiently strong for giving a safe joint over the meeting edges of the edge flange. The milling of the cardboard material also can be made from a line further out from the bottom than illustrated in the drawings but not outside a line 1 2a corresponding to the upper edge of the container to be formed.
As mentioned above the blank is formed with an integral piece of material, and the different portions are defined from each other only by means of creasing lines extending along the edges 4, 5, 8, 9 of the bottom and as a limit 14, 15 between the joining pieces 10 and the adjacent sides 2, 3, 6 and 7.
For providing rounded corners and an obliquely downwards directed edge flange at the upper edge of the container the long sides 2, 3 are along their outer edges bow formed at 16 and 17 corresponding to the bottom corners, for instance the corners 18, 1 9. Parallelly with the outer edge of the long sides there is a creasing line defining a strip 10. In a ready container the said creasing line provides the upper edge of the container bowl.
The erecting of the container is made with the plastic laminated surface turned upwards, i.e.
towards the inner of the container, and the erecting is made in that the short sides 6 and 7 are fold up and immediately thereafter the edge flange strips 20 are fold down. The pockets or ears which are formed by the joining pieces 10 and the outer portions of the long sides 2, 3 are fold in towards each other and toward the short sides 6 and 7 and are clamped together, and finally the upwardly projecting ear 24 the material of which has been thinned by grinding is fold down over the joint 25 of the edge flange 20 and to the rear side of the edge flange. In figure 2 one ear 24 is shown fold down whereas the opposite ear is shown upwardly projecting.
In order to avoid liquid, fat or any other type of packed goods to penetrate into the pockets which are formed between the short sides 6, 7 and the long sides 2, 3 and for assuring that the container is joined to a stable unit the short sides are welded straight through the container following two weld lines 21, 22, one extending parallelly to the meeting edges of the long sides and the other extending parallellly with the upper edge of the container. Preferably the weld lines are provided just adjacent the said joint and the upper edge respectively.
By the reduction of the cardboard material in the milling operation the projecting ear 24 is made a relatively thin and easily foldable piece of material which ca,1 be easily handled and which still gives the edge flange joint a sufficient stabilization. As best illustrated in figure 3 the thickness reduction of the material appears in two steps since the inner line of the milling of the joining piece 10 is located on a lower level than the corresponding line of the short side 7, and this two step reduction gives a soft transition to the upper edge 26 of the container. At the same time- the thickening of material along the said upper edge emanating from the joint ear 24 is neglectable.
It is to be understood that the above specification and the embodiment shown in the drawing is only an illustrating example and that all kinds of different modifications may be presented within the scope of the appended claims.
