Description

Description The invention relates to a container for liquids, pastes and the like having four side panels which adjoin each other at four side edges and a bottom panel. Such containers are generally known in practice. They can .be used in particular for receiving liquids or pastes. The problem underlying the invention is to provide an im proved container of this type. According to the invention this problem is solved in that the bottom panel consists of four subpanels adjoining each other in roof shape. Preferably, the four subpanels of the bottom panel are defined by edges, a first lower edge ex tending away from the lower end points of two first opposite .side edges and enclosing with the associated side edge an angle of less than 90*, the first lower edges meeting each other in a central point lying in the cross-section centre, a second lower edge extending in each case from the lower end points of the second opposite side edges to said centre point, the lower end points of the second side edges lying higher than said centre point and third lower edges extending from the lower end points of the first side edges to the lower end points of the second side edges. This configuration makes the container suitable both for receiving a large volume and also suitable for completely expelling this volume from the container. The container is therefore particularly suitable for receiving pasty material, for example tomato preserves. In the state just described the container has a relatively large volume so that it can receive a relatively complete filling. At the same time the container makes it possible to dompletely expel the con tent. Advantageous further developments are described in the sub sidiary claims. The first side edges and/or the first lower edges may be obtained by welding. The container is advantageously pro vided with an opening which is preferably closable. The opening may be surrounded by an externally projecting neck comprising an outer thread. The neck is preferably welded on. The opening may be sealed by a region of reduced wall thickness and/or different wall material. Two opposite side walls may be joined in each case to a free tag. The container may be opened in that each of the tags is gripped by a hand and the tags then torn apart. The container walls consist prefer ly of paper or polyethyl enated paper or polyethylenated aluminium or a multilayer structure of paper, aluminium and/or polyethylene. The invention further relates to a blank for a container according to the invention of the type described below. Said blank is characterized by four adjoining side panels and cover panels each adjoining two adjacent side panels, two lower edges extending inwardly in arrow manner from each outer side edge and the centre line and two folding lines extending respectively in arrow manner within the arrow shaped lower edges. Using such a blank, i.e. such a start ing body, a container corresponding to the invention can be made in simple manner. Advantageous further developments of the blank according to the invention are the subject of further subsidiary claims. -2- Examples of embodiment of the invention will be explained in detail hereinafter with the aid of the attached drawings, wherein: Fig. 1 is a front view of the container, Fig. 2 is a side view of the container illustrated in Fig. 1, Fig. 3 is a lateral section through the container illus trated in Fig. 1, Fig. 4 is a cross-section through the container illustrated in Figs. 1 - 3, Fig. 5 is a perspective view of said container, Fig. 6 shows a blank for making said container, Fig. 7 is a perspective partial view of the bottom of said container, Fig. 8 shows the container after complete squeezing out of the content thereof, Fig. 9 shows a blank for a further container, Fig. 10 is a side view of a further container with tags adjoining the side walls, Fig. 11 is a front view of the container illustrated in Fig. 10, Fig. 12 shows a further embodiment of a container in a front elevation, -3- Fig.- 13 shows the container illustrated in Fig. 12 in side elevation, Fig. 14 shows an embodiment of a- container obtained from the blank of Fig. 9 in front elevation and Fig. 15 is a side view of the container illustrated in Fig. 14. The container 2 illustrated in Fig. 1 comprises four side panels which adjoin each other at. four side edges and a bottom panel. The bottom panel *consists of four- subpanels which adjoin each other in roof-manner and which will be described in detail hereinafter. The container 2 comprises two first opposite side edges 4 and two second opposite side edges 6. With the aid of the perspective view of Fig. 7 the structure of the bottom panel becomes part i.cularly clear. In all the drawings, corresponding parts are provided with the same reference numerals so that these parts need not be described again every time. From each of the lower end points of the two first opposite side edges 4 a first lower edge 5 extends which encloses with the associated side edge 4 an angle of less than 90*. Since the first side edges 4 extend vertic ally the first lower edges thus extend upwardly. The first lower edges 5 meet each other in a central point 8 which lies in the cross-sectional centre (cf. also Fig. 4). As further apparent from Fig. 7, from the lower end points 9 of the second opposite side edges 6 in each case a second lower edge 10 extends to said centre point 8. The lower end points 9 of the second side edges 6 are higher than said centre point 8. The second lower edges 10 thus ex tend from the lower end points 9 downwardly. Since the lower end points 9 of the second side edges 6 are higher than the centre point 8 and since also said centre point 8 is higher -4than the lower end points of the first side edges 4, the lower end points 9 of the second side edges 6 necessarily lie higher than the lower end points of the first side edges 4. The vertical structure is thus as follows: At the very bottom there are the lower end points of the first side edges 4. Somewhat higher lies the centre point 8. Somewhat higher still are the lower end points 9 of the second side edges 6. Furthermore, third lower edges 7 are present which extend from the lower end points of the first side edges 4 to the lower end points of the second side edges 6. As a result the bottom panel consists of all subpanels. Each subpanel has the form of a planar triangle. Each sub panel is defined by a first lower edge 5, a second lower edge 10 and a third lower edge 7. Fig. 6 shows a blank for making the container of Figs. 1 to 5. Said blank could also be regarded as development into the plane. .The blank consists of four adjoining side panels and cover panels which adjoin every two adjacent side panels and are roof-shaped in each case. Two lower edges 5 extend inwardly in arrow-like manner from each outer side edge 4 and the centre line 4. Furthermore, in each case two arrow like fold lines 7 are present which extend within the arrow like lower edges 5. To make the container the two side edges 6 are folded. Thereafter the two outer side edges 4 are joined together. Two respectively associated lower edges 5 are also joined together; thus, the two centre lower edges 5 and the two outer lower edges 5 are connected to gether in each case. This then gives the bottom panel al ready described above. The container may be made from paper or polyethylenated aluminium. It is also possible to use polyethylenated paper. -5- Another possibility is to implement the structure with a multilayer paper/aluminium/polyethylene. This structure can be squeezed to expel the entire content, for example tomato preserves. It is apparent from Figs. 1 to 9 that the side edges 6 and the bottom edges 7 and 10 consist of folds. Said folds may also be referred to as "crisis lines". The folds keep the container bottom stretched so that the container can re ceive a lot of filling material. At the same time, it is possible to squeeze the content disposed in the container. In this manner the pasty material, for example tomato pre serves, can be expelled. In Fig. 4 the folds can be seen in plan view. The centre point 8 is the intersection of the folds; it can be referred to as "peak" as in a roof. The first side edges 4 and the first lower edges 5 are welded, i.e. obtained by a welding. Furthermore, the container 2 is provided with an opening which is closable. The opening at the upper end of the container is surrounded by an out wardly projecting neck 1 having an outer thread. Instead of the neck a transverse weld could also be provided. The upper inclined shoulders 3 are also welded together. The neck Lprovided with the thread is welded to the container in the region of the zone 11. The folds in the container bottom keep the container "swollen" and squeezable like a toothpaste tube. This ensures a large container content. Fig. 8 illustrates the fact that the container can be com pletely squeezed, i.e. squeezed out, to expel the entire content (like a toothpaste or rather a tomato concentrate). -6- Fig. 9 shows a development in the plane of a further embodi ment of the container. In this case the opening consists of a region 13 of reduced wall thickness or different wall material. Furthermore, the opening is provided at one of the two upper cover walls and not at the upper intersection line of the two upper end panels. Fig. 10 shows a side view of a further embodiment. Two opposite side walls are each connected to a free tag 16. The two tags 16 also lie opposite each other. The tags 16 can be gripped by the fingers for opening the weld 12 of the container. Fig. 11 shows a front view of the same container. Fig.. 12 shows a front view of a further embodiment. In this case the closable opening is likewise in one of the two upper inclined end panels of the container. Within the neck 14 there is a region 13 of reduced wall thickness or different material which can easily be pierced. Originally, this region 13 is closed. It can be pierced to permit emptying of the container. After partial emptying the con tainer can be closed again by a screw cap which is screwed onto the thread of the neck 14. The embodiment of Figs. 14 and 15 is obtained from the blank illustrated in Fig. 9. The invention implements a container in partial form with a large visible surface but also a large capacity. The con tainer is preferably suitable for tomato concentrate and other pasty substances. The container has a pleasant appearance. It solves the problem of using paper also for toothpaste tubes, tomato tubes, mayonnaise tubes and other paste tubes. A cap with a tip for piercing the region 13 may be screwed onto the closure thread. The four-clench structure of the bottom makes it possible to fill the con tainer well in the form of an arrow, or to be more exact the tail of an arrow. In combination with the inclined -7welds 5 which are inclined to the bottom and converge in the centre point 8 and the other border lines or folds a new and original four-clench form is obtained which has the particular usefulness of implementing a structure which offers a maximum content and a maximum visible surface per ceivable in the display shelf. The container according to the invention is therefore particularly suitable for re placing the hitherto known container of extruded aluminium in cylindrical form. The use of cheaper paper is made possible. The new container can be more completely com pressed than the known cylindrical tubes, it is very econ omical and can be imprinted in simple manner with many colours. -8-
