Definitions

  • the invention relates to a squeezable container, in particular single-use or reusable packaging, for pasty, liquid or powdery filling goods, which is made of a rigid, flexible and flat material, which is formed by bulging or shaping a base and simultaneous erection and bulging of two side sections and tight Connecting the opposing side edges or flanges of the side sections is formed, after which the filling of the filling material and the closing of a section left open for this purpose take place, the flanges or edges lying one on top of the other not being connected at least at one point to form at least one flat passage channel, which channel in An outlet opens, the walls of which lie flat on top of one another in the region of the passage channel and, due to the prestressing of the arched material, an increased resistance to bulging away from one another and a lip seal-like compression against one another and the arched outlet is at least largely self-closing.
  • Such a squeezable container is known from DE-A-24 24 718.
  • This known container consists of two halves, which are made of plastic films in the deep-drawing process.
  • a relatively expensive plastic be used that has sufficient internal stress, but two different cuts must be made and precisely connected to one another.
  • Such a plastic also offers considerable resistance to the removal of a previously completely connected closure part.
  • the self-closing opening is therefore present from the outset and is opened by increasing the internal pressure.
  • there is a risk that such an increased pressure occurs unintentionally during transport or storage and that deliberate losses occur even before the contents of the container are removed.
  • the container mentioned at the outset is characterized in that it is formed from a single flat material blank, in which a middle section connecting the two side sections is formed as the bottom, that the material material is coated cardboard and that the flat edge penetrating the edge of the container Channel opens into a tongue that is closed, can be torn off or cut off before use, the passage channel remaining largely closed even after the tongue has been removed.
  • Such a squeezable container can thus be produced from a single blank and from a very inexpensive material. It can initially be shipped hermetically sealed and stored, and once the user has opened it, the content remains largely protected against unwanted leakage. It is advantageous that the walls of the channel are arranged within the edge of the container and are correspondingly firmly on top of one another, the only difference from the connected edges being that the connection is interrupted in this area. In this way, even after removal of the corresponding remainder of the tongue, which opens the outlet itself, there is a sufficiently tight closure to be able to keep the contents for at least a time, even though the container is made of cardboard.
  • the container according to the invention is thus suitable as a sample pack for those samples which have to be generously dimensioned but which are not required by all users at once. Furthermore, such a container is suitable for filling goods which, for example, should be able to be removed one after the other by several users.
  • the container can therefore contain, for example, two or more portions of a filling material. Possibly this container can even replace a smaller tube with correspondingly wide edges and a correspondingly long outlet channel, because the channel walls flatten out again at least in some areas after squeezing out a certain portion of the filling material. H. will be close together.
  • the closing and sealing effect of the channel walls can be supported by the fact that the user presses them together again after removing part of the filling material. Due to the material used, however, it is largely self-closing waiting. This can be supported by an embodiment of the invention of considerable importance worthy of protection, which can consist in that at least the regions of the container or the container edge adjacent to the channel are resilient, so that the initially flat surface. Channel can be arched when the filling material is pressed out, and the channel spacings which are the most distant from one another and are formed by the fastening of the cut edges can be moved relative to one another. After completion of the removal process, there is a springback with a corresponding automatic closure of the channel. When the filling material is squeezed out, a certain resistance when spreading the channel walls is overcome, which, after the removal of the filling material has ended, again results in the channel closing essentially automatically.
  • a transition with an angular cross section can be provided at least in some areas.
  • Such an angled transition strengthens the mutually directed forces of the cavity walls or the channel walls starting there, particularly in this transition region.
  • Such an angled transition is particularly feasible when using cardboard or cardboard-like material.
  • the curved side walls bordering the cavity practically touch each other at the edge of this angular area and are thus already directed towards one another, so that the channel beginning here is already closed at the beginning by its walls lying on top of one another.
  • the restoring forces are also correspondingly strong when the pressure on the cavity of the container stops when the filling material is pressed out.
  • the spreading bottom and the outwardly curved walls of the cavity are expediently subject to a tension acting on the outlet channel in the sense of a compression due to the shape and the choice of material.
  • FIGS. 1 to 10 A total of six differently designed containers 1 are shown in FIGS. 1 to 10, but all of them have the same reference numerals, because their structure is similar in principle.
  • the parts and details belonging to them also have the same reference number. Namely, these containers are essentially formed from a blank 2, in which only the parts to be described for the outlet channels can be arranged differently.
  • the blank 2 is bent in a U-shaped manner to obtain a container according to FIGS. 2 and 3, wherein in the area of the U-cross bar a bottom 3 which is curved in the projection and which is curved in one direction in side view is formed, which in FIG. 3 has a spacing and has a spreading function for the inner cavity 4 with the filling material.
  • cardboard or a cardboard-like material or a layered material containing such a material such a container 1 becomes inherently stable, so that the pressure of the filling material does not have to bulge out of the container 1.
  • the cavity 4 is surrounded by two walls 5 which are deformed away from each other and arched and flat at the edges 6 over a certain width lie on each other and are firmly connected here.
  • gluing, sealing or welding can be considered.
  • All of the exemplary embodiments have in common that in the edge region of the container 1 located outside the base 3, the flanges or edges 6 lying one above the other to form at least one flat passage channel 7, which are at least one point - possibly also several such points at the same time - are not connected
  • Channel 7 opens into a closed, tear-off or cut-off tongue 8 or the like.
  • the outlet opens and the walls 9 of FIG. 3 or 7 lie one on top of the other when not in use, so that the channel 7 initially has no passage cross section, i.e. the container even after removal the tongue 8 seals and keeps closed. If only a part of the filling material is removed from the container, the rest can therefore still be kept, although a reclosable closure lid or the like is not provided or necessary.
  • the tongue 8 with the initially closed emptying opening or the emptying channel 7 lies opposite the bottom 3. 6 and 7 in particular, the tongue 8 with the emptying channel 7 is arranged in a lateral edge region adjacent to the spreading floor 3, where the angled transition 10 according to FIG. 7 is particularly strong, so that the self-sealing becomes large here.
  • the container can then be emptied from the flatter to the thicker side.
  • the outlet channel 7 has a substantially constant width and, moreover, this channel 7 is also surrounded by an edge 11 in the region of the at least partially removable tongue 8.
  • the width of the edge 11 of the channel 7 is approximately the same as that of the container edge 6, which has advantages in manufacture. 9, however, shows an exemplary embodiment in which the edge 11 has a greater width in the region of the emptying channel 7, because the entire blank width is also chosen to be constant in the region of the channel 7, which results in a simple blank 2.
  • the tongue 8 can one or more tear-off aids, e.g. B. notches 12 or the like. In the surrounding edge 11, which are arranged in an approximately perpendicular to the channel 7 area. In the exemplary embodiments, two such notches 12 lie opposite each other.
  • the tongue 8 can be cut off in a correspondingly straight line, or when torn off, the user can tear both on one side and on the other side of the channel.
  • the container edges 6 delimiting the emptying channel 7, which continue into the channel edges 11, lie flat and thus close to one another even after removal of the tongue part 8 which exposes the opening.
  • FIG. 8 shows a modified exemplary embodiment in which the channel 7, which penetrates the edge 6 of the container 1 flat but at right angles, tapers in the direction of emptying, at least in the region of the tongue 8.
  • an emptying channel 7 could of course also be provided in the other exemplary embodiments.
  • the tongue 8 surrounding the emptying channel 7 according to FIG. 8 is provided with an approximately triangular cross section, a triangular side being formed by the container itself in the angled transition 10, while a further triangular side is formed by an edge running at right angles thereto, approximately flush with the ground 3 and the third side of the triangle are formed by an oblique edge.
  • an inverted or more acute-angled arrangement is also possible.
  • a tongue side running approximately at right angles to the container edge 6 can, according to FIGS. 6 and 8, be flush with the bottom 3.
  • the corresponding emptying channel 7 is located in an area in which the angle between the side wall 5 and the container edge 6 or the channel inlet is as acute as possible.
  • the self-closing forces are correspondingly good here.
  • Fig. 3 it can be seen that the bottom 3 integrally connected to the container side walls 5 is approximately oval and curved inwards with respect to the container side walls 5, but the transition from the bottom 3 itself into the side walls 5 is essentially rectangular and one over the bottom 3 parallel to the container walls 6 running meridian line is straight. In this way, a relatively stable bottom 3 results, which also when using the container, i. H. when squeezing its content remains so that it can then take over its spreading function again. Nevertheless, the choice of material allows a practically complete squeezing, also destroying the bottom area, if the container is to be squeezed out completely.
  • a plurality of notches 12 can be arranged one behind the other in the direction of emptying, in particular in the case of a tapering emptying channel 7. This allows the outlet cross section to be varied. If the outlet channel 7 does not taper, but if several notches are provided one behind the other, the sealing surface can be enlarged or reduced in this way. At the beginning of an emptying process, it is advisable to use the notches furthest away from the cavity 4 in order to achieve the longest possible sealing surface. The channel length can then be shortened for the last emptying of the container 1.
  • a container 1 which - as can be seen from the blank 1 according to FIG. 1 - is very easy to produce, does not require any special closure device, often made of metal or plastic, and is nevertheless suitable both as a disposable container and as a container for repeated removal operations . He can thus z. B. contain cosmetics such as shampoos, where it is often prescribed that the user should first use a first portion and then a second portion. With a sample container consisting only of plastic film, this is only possible with great difficulty, if at all. Such a container can also be used to hold mustard, etc.
  • the configuration of the squeezable container according to the invention is particularly evident in the enlarged sectional view of FIG. 10.
  • the tongue 8 has just been severed, and yet the walls 9 of the passage channel 7 lie closely on one another, at least at the outer end.
  • the special shape of the container shows that the longitudinal section through the channel 7 and the container area adjacent to it is Y-shaped, the two legs of this Y being formed by the container walls 5, while the smear of the Y is formed by the passage channel.
  • This special shape causes the prestressing due to the cardboard-like rigid material, so that the walls 9 lie on one another with a certain closing pressure. Even after a part of the tube content has been pressed out, the walls 9 have a self-closing effect due to this prestressing.
  • passage channel 7 and the tongue surrounding it can also be arranged at a transition, in particular a corner, between a side edge 6 and the edge opposite the bottom 3, as is additionally indicated in FIG. 5 with broken lines .
  • FIGS. 13 and 14 An embodiment of the invention of its own worthy of protection is shown in FIGS. 13 and 14, FIG. 13 showing a top view of the tongue 8 with the passage channel and FIG. 14 showing a cross section in a partially diagrammatic view through this tongue 8. It is provided that the superimposed walls 9 of the channel 7 are embossed and / or profiled transversely to the emptying direction. A wavy profiling 14 can be seen particularly clearly in FIG. 14, through which an even better sealing of the passage channel is achieved even after the container has been opened and the outer tongue 8 has been separated.
  • This profiling is particularly useful if the passage is arranged in a region of the container with a very acute angle between the walls 5, that is to say in particular on the edge opposite the bottom 3, where the prestressing of the side walls in the closing direction of the channel is lower. Furthermore, this additional sealing measure is also advantageous - regardless of the arrangement of the emptying channel on other sides of the container - if a relatively liquid medium is to be contained in the container.
  • FIGS. 11 and 12 show containers in which the base 3 has a lenticular and inwardly curved shape which is advantageous per se.
  • An embodiment is indicated in FIGS. 11 and 12, in which the expanding base 3 or the corresponding central section of the blank is polygonal, in particular hexagonal. This hexagon shape can be seen particularly well in the diagrammatic representation of a container 1 in FIG. 12. From FIGS. 11 and 12 together it is clear that the regions 3a of this base 3 which are close to the edge and, in the exemplary embodiment, diagonally inward, have an approximately triangular shape and the base part connecting them 3b are approximately rectangular. Such a container can possibly even be placed well with the base region 3b on a rod-shaped holder or the like which fits between the regions 3a.
