Definitions

  • the invention relates to a squeezable container, in particular single-use or reusable packaging, for pasty, liquid or powdery filling goods, made from a single, stiff, but flexible, cardboard-like flat material blank, which is arched inwards and outwards by bulging a bottom or middle section of the initially flat blank simultaneous erection and bulging of two side sections is formed until the opposite side edges or flanges of these side sections are joined and sealed, after which the filling material is filled and the side that is still open, preferably opposite the central section, is closed.
  • Such containers are already known and attempts have been made to replace the tubes, which are often made of metal, with less expensive materials.
  • Such tubes usually still contain a fixed, reclosable outlet for a screw cap.
  • Squeezable containers are already known, which usually contain a much smaller amount of bulk material and are intended for single use. These usually consist of plastic film and are z. B. arched like a pillow. These disposable containers for small quantities can be torn open or cut, creating an emptying opening. If the entire filling quantity is not removed in the process, such containers can hardly be stored because the contents can flow out of the openings formed, since the container itself cannot hold this contents due to its softness. The user then has no choice but to either consume the material or throw it away.
  • the invention has for its object to provide a container of the type mentioned, in which an expensive emptying device with a closure is avoided, but the container does not have to be emptied immediately after opening in order to use the contents; rather, the container should be able to hold the contents even after opening, without the need for a special attachable closure device.
  • the container of the type mentioned is characterized in that the flanges or edges lying one above the other for forming at least one flat passage channel are not connected at least at one point, which channel or the like in a closed, tear-off or cut-off tongue or the like before use
  • the outlet opens, the walls of which lie flat on top of one another in the region of this passage and, due to the pretensioning of the arched cardboard-like material, there is increased resistance to bulging away from one another and a lip-like compression against one another, at least when cutting or tearing off have area, and that the passage channel remains largely closed even after removal of the tongue or the like and the open outlet is at least largely self-closing.
  • Such a squeezable container can initially be shipped hermetically sealed and stored, and once the user has opened it, the contents remain largely protected against unwanted leakage.
  • the abs-retaining bottom which gives the container a shape that is stable in itself, so that the contents do not flow out automatically after the opening of the outlet.
  • a separate outlet device with screw cap or the like A relatively expensive part, which has to be manufactured separately and placed in the container and fastened there, is advantageously avoided.
  • 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 thus, for example, two or more pores contains 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 become flat again, that is to say, close to one another, at least in regions after the squeezing out of a certain portion of the filling material.
  • the closing and sealing effect of the channel walls can be supported in that the user presses them together again after removing part of the filling material. Due to the material used, however, a closure is largely to be expected by itself. This can be supported by an embodiment of the invention of considerable importance worthy of protection, which can consist in that at least the areas of the container or the container edge adjacent to the channel are resilient, so that the initially flat channel can be arched out when the filling material is squeezed out and the by the fastening of the cut edges, the most distant channel 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 pressing the filling material, a certain resistance to the spreading of the Namely - channel walls overcome which leads to the essentially automatic closing of this channel again after the removal of the filling material.
  • 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 surrounding the cavity practically touch each other at the edge of this angled area and are thus already facing each other, so that the channel starting here is already closed at the beginning by its walls lying on top of each other.
  • 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 expanding floor and the outwardly curved walls of the cavity are expediently under 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 region of the U-cross bar a bottom 3 which is approximately oval in projection and which is curved in one direction in side view 3, which has a spacing and spreading function for the inner cavity 4 with the filling material according to FIG.
  • 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 the container 1.
  • the cavity 4 is surrounded by two walls 5, which are deformed away from each other and arched and lie flat on the edges 6 over a certain width 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, at least one point - possibly several such points are also possible at the same time - the flanges or edges 6 lying one on top of the other are not connected to form at least one flat passage channel 7, which channel 7 opens into a closed, tear-off or cut-off tongue 8 or the like.
  • the outlet 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 also Removing the tongue 8 seals and keeps closed. If only a part of the filling material is removed from the container, the rest can still be kept, although a lockable 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 11th have, which are arranged in an area approximately at right angles to the channel 7. In the exemplary embodiments, two such notches 12 lie opposite each other.
  • the tongue 8 can be cut in a correspondingly straight line, or when tearing 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 the tongue part 8 which opens the opening is removed.
  • 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 be aligned with the bottom 3 as shown in FIGS. 6 and 8.
  • 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. Are accordingly good here the self-closing forces.
  • Fig. 3 it can be seen that the bottom 3 integrally connected to the container side walls 5 is approximately oval and arched inwards relative to the container side walls 6, 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.
  • 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.
  • 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 first use the notches that are 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 manufacture, does not require any special closure device, which is often made of metal or plastic, and is nevertheless suitable both as a disposable container and as a container for repeated removal processes. 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 results in the fact that the longitudinal section through the channel 7 and the adjacent container area 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 wave-shaped profile 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 expedient if the passage channel 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 3 opposite the floor, 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 3 a of this base 3 which are close to the edge and, in the exemplary embodiment, obliquely inward, are approximately triangular and connect them Bottom part 3 b are approximately rectangular. Such a container can possibly even be placed with the bottom region 3 b on a rod-shaped holder or the like, which fits between the regions 3 a.
