Description

Containers for liquids. Powder or analog products There will be more and more containers are used to hold liquids or powders, the consist of a cell that has been produced by hot deformation and its Opening is surrounded by an edge on which a closing surface after filling the Cell is attached. Such containers can only stand on the floor of the cell, so that the closing surface is attached to its upper end in a horizontal position, since the protrusion of the edge around the whole cell does not have a balance in one allows another position. For small-capacity containers, this is not significant.

However, it becomes more difficult if the container holds a larger liquid or is to absorb the amount of powder, e.g. 1 1 milk.

The hot deformation process can only be used relatively effectively apply shallow depth of cell. To increase the capacity of the Cell must have their bottom and their opening enlarged without reducing the depth is enlarged at the same time. Since this cell is always on the area with the largest Dimension rests, this size becomes a particular obstacle in numerous cases when used as a milk container, for example, or with a view to adjusting in a refrigerator.

This invention addresses these disadvantages by providing a container to meet, the form of which is such that it can easily respond to a its side surfaces both in the open and also in the closed state can be. It can of course also be stored or stored in a lying position will.

Namely, this invention has a container for liquids, powders or analogous products to the object comprising a cell, the opening of which is through an outer edge is surrounded, as well as a closing surface attached to this edge. This container is characterized in that on one of the sides of the cell the The end of the outer edge and the edge of the floor lie in one and the same plane, which runs perpendicular to the median plane of the container. The end of the edge and the Edge of the bottom form a base for the said container.

Preferably, the opening of the cell has a rectangular shape, and the base is from the end of the edge of one of the two small sides formed this rectangle and the edge of the bottom of the cell.

This container - like all containers consisting of one cell - can be used during its transport or its storage or warehousing on its Ground. However, it can also be placed on the base on the side and is formed even on one of the narrowest sides of the cell, and on this Way to stand vertically or upright.

A pouring opening is preferably located on the opposite side of the base Attached to the end of the container so that even an open or partially emptied one Container this can stand on the aforementioned base. Stability and rigidity of the container are guaranteed in this position.

Various other features and advantages of the invention emerge the following description of an embodiment, which is only an example without limitation of further application possibilities and those on the attached Drawings is shown.

The illustrated container for liquids, powders or similar Products: is a type that. essentially.

comprises a cell (i), which on its periphery with an opening (3), an outer edge (2) and a support for a closing surface (5) is provided. This foil can be made of the same material as the cell (i) or according to the Purpose of use made of a different material. In the illustrated embodiment the opening (3) and the bottom (4) opposite this opening are the sides with the largest drains of the cell. The edge (2) is through with the bottom (4) Connected side surfaces, which are preferably at right angles to said edge (2) and run perpendicular to the opening (3) and the plane of the surface (5). One of these Side surfaces (6), however, are not flat and have two parts: one part (6a) perpendicular to the edge (2) and a part (6b), which is blunt with the part (6a) Forms angle and is attached to the end edge (7) of the bottom (4). This edge (7) and the outer edge (8) of the edge (2) lie in one and the same plane (P), which runs perpendicular to the central plane (M) of the container which intersects the surface (6).

The plane (P) and the surface (6) represent a base for the Container. Regardless of the degree of filling of the container (1) - when this is on the edges (7) and (8) - namely the vertical ends to Base, which runs through the center of gravity of the container, in the area between the edges (7) and (8), and the container is always in equilibrium.

In the example shown, the part (6b) of the side surface is located (6) in plane (P) and represents part of the base area. The container can naturally also stand flat on the floor (4).

In a preferred embodiment, the opening (3) has the shape of a Rectangle (Fig. 2), and the edge (8) of the edge (2) is on one of the small sides of this rectangle, so that the on this base container stands upright. In addition, the container has an essentially trapezoidal longitudinal cross-section, while the cross-section is perpendicular to the median plane The shape of a rectangle is also opposite to the opening (3) Bottom (4) of the cell with the two sides (9) adjoining the side surface (6) of said cell connected by beveled edges (10) (Fig. 7). This allows the containers are stacked in a lying position on top of one another and side by side; a container lies alternately on the surface (5) both horizontally and horizontally vertical with a container leaning on its bottom. In this way In a first stack there is a container (ia) on the surface (5) and its bottom (4) carries the bottom (4) of the container above, while in a second Stack of the first container (ib) on the floor (4) and the surfaces (5) of the two overlying containers are supported against each other. Snuggle up to every stack the edges (2) of the container into the recess created by the beveled Edge (io) of the container of the adjacent stack is formed.

This arrangement allows a number of containers in one proportionately can be stored in a limited space and transported without difficulty.

On the other hand, the containers in the one shown in Fig. I can be upright Position easily housed in a refrigerator or other analog room will.

The cell (1) forms one at one of the angles of its opening surface Cut-off corner (12) (Fig. 2) into which a pouring opening (14) is cut (Fig. 3). The edge (2) is widened at this corner; the area (5) is in the same Like the rest of the edge (2) only in a thickness (12a) analogous to that of said edge (2) welded shut. On a surface (12b) that adapts to the surface (12a) connects to the outside, the weld seam is narrower, while the tip (12c) the corner is free and a kind of separating gap between the surface (5) and the Represents a cell which enables the pouring opening (14) to be exposed.

A slight incision is preferably made under this free corner (12c) (15) (Fig. 4) made in the edge (2), which represents a scratch. It is open in this way possible to the container by folding the corner edge to the right according to 4 to open, whereby the end (12c) of said corner (12) is severed and the surface (5) pressed away from the edge (2) until the opening (14) is exposed will. The remaining surface (5) remains connected to the edge (2).

Then when the container has the desired amount of liquid has been emptied, the area (5) (to the left in the illustration) can be above the area (12b) can be closed again by folding, as shown in Fig. 6. This will the ingress of dust into the container is avoided.

According to another embodiment (fig. 8, 9 and io), for manufacturing of the pouring opening the two adjoining sides of a substantially triangular one Foil (20) made of soft material, which along its center line (21) in two parts folded between one (2a) of the sides of the adjacent edge of the corner (12) and attached to the corresponding edge of the surface (5). The outer surface of this slide (20) is on the edge (2a) of the cell on the one hand and on the surface opposite the Closing surface (5) on the other hand welded and separates them from each other in this way through some kind of fold. On the other hand, on the second side (2b) of the edge (2) in near the corner (12), i.e. on the side corresponding to the enlarged part (13), the surface (5) is welded to the cell in such a way that the closure of the container is sealed, whereby the both parts of the soft film (20) been pressed tightly against each other.

Preferably the area of the cell (i) below the corner (12) slightly incised according to a sloping line (22) so that something below the upper part of the film (20) and the beveled corner (12) created a tear will.

When the container is to be opened, the cell becomes as well as the corresponding one Closing surface (5) torn open according to this break line (22). The removal of this Piece of the container leaves a slight tear in the folded film (20).

As a result, the surface (5) and the cell (1) are no longer pressed against each other.

The foil (20) is made of a soft material, e.g. a thin sheet of aluminum paper. It can therefore be easily deformed, in particular to unfolded between the two parts and then to be folded back outwards, so that a pouring opening is created, the essentially has an inwardly opened V-shape, as shown in FIG. In this position there is the opening (20) for guiding the liquid or any other liquid other product contained in the container ready, and it also allows emptying of the container.

Thanks to the soft nature of the film (20), the opening can also can be closed again by simply pressing the surface (5) against the edge (2). Curving the opening can even create a locking clip for the container can be produced - as shown in Fig. 3. For this you need with partially emptied Container only to press the closing surface (5) against the edge (2) of the cell, whereby the two parts of the soft film (20) that are still facing outwards, are pressed against each other. Then this film - (20) around the outer surface of the edge (2) in the Folded so that the edge of the face (5) Remains as close as possible to this outer surface and thereby the possibilities of one Escape of the liquid or any other contained in the container Product can be restricted to the outside world. The ingress of dust or others This also prevents substances from entering the container.

The pouring opening created in this way has both advantages a simple use as well as a great security, since they are consecutively Pour opening and can be used as a locking clip.

In addition, a pouring opening of this type can easily be carried out simultaneously can be created with the container without changing the manufacturing method of the container. The triangle (20) made of soft material, which is folded so that there are two of the same Has parts, is attached with one of its edges to the strip, which as Closing surface (5) is intended to serve before it comes to a point at right angles to the one to be closed Cell is guided. The triangle is indicated by this strip above the cell in brought in such a way that it is next to the beveled corner (12). Then, when the surface (5) is welded to the edge (2), the second Edge of the triangle attached to said edge (2a) while it is between the cell and there is no direct connection in the actual edge. On the side (2b) the Edge in 13 extended at right angles to the sawed-off corner (12), and the direct Attachment takes place between the film (20) and the outside in such a way that the previously filled container is tightly closed.

For the formation of the pouring opening is therefore neither a change in Manufacturing method of the container still required for the closing process.

You only have to fold the soft material and fold it beforehand Attach the triangle to the strip that will serve as a closing surface and for one exact centering of this stripe on the cell is what is easy to do today can be achieved with the help of a photo-electric cell or an analog system.

The material required to make the pouring opening is very inexpensive, so that the cost of the container is not significantly affected0 on the surface (5) a dotted line can be provided to indicate the opening limit, as shown in Fig. 26 in Fig. 8.

The bottom (4) of the cell is preferably formed in its central part an inwardly directed bulge that is hollow and allows gripping of the container facilitated.

The tip (17-) of this bulge lies in the same plane as the Edge (2) and is preferably welded to the surface (5), whereby the bending stiffness this area is increased.

Of course, the cross-section of the container can vary depending on the intended use vary. The side surface (6), which forms the base surface, could also be a different one Have shape.

In all cases, the transport and relocation of the container provide thanks to the possibility of compact stacking on the one hand and thanks to the easy gripping on the other hand no difficulties.

The stability of the container is also in the lying position Position as well as in an upright position guaranteed. This results in the Users have a great deal of security because the container is on one of its small sides self its stability when opened or partially emptied preserved.

The cell can be made of any opaque, translucent and transparent thermoplastic material are made while the closing surface can be made of the same material as the cell (i), aluminum or other Metal or a composite material, e.g.

Aluminum-polypropylene or aluminum-paper. This area will eventually printed.

Thanks to the use of aluminum in the closing surface, ultraviolet Rays withheld and thus the contents of the container during its storage to be protected. In the case of the container according to the invention, this advantage is important, because the closing surface has a large area and can easily be between the Contents of the container and e.g. lighting lamps of a counter or a display be arranged, the shape of the cell remains simple, as the side surfaces of the Cell and even face (6) have at least a part near the edge, the one acute interior angle or at most a right angle with this edge forms, whereby the displacement and in particular the retraction of the shaping tools be relieved.
