Description

PACKAGING AUTOSOPORTAB E FOR SOLVENTS DESCRIPTION OF THE INVENTION The invention relates to a self-supporting container for fluid media, made of a flexible material, sealable, with a base, with side walls, with sealing seams that join the walls and with a means of emptying. The known containers of fluid media of this type are currently sold commercially as color bags and filling containers for cleaning agents. The material of the container is a plastic sealable in various layers to produce a sealed and rigid container so that it is able to self-support when filled. The side walls are pressed down, flat at the top and joined to a longitudinal sealing seam extending to the base, while the base is further sealed inward and thereby the lower edges of the side walls are expanded outwardly. so that the known container, which is wider at the base and narrower at the top, can be kept straight on the lower edges of the side walls. It is provided, either a closure or a cut or a marking in the upper area as the emptying means, so that the end user opens the closure or starts or cuts a tab to be able to pour the liquid. The known self-supporting bags achieve their ability to stop at a high cost in terms of multilayer plastic film material, which cause recycling problems because the separation of the individual layers by material is difficult. The insertion of a strip of additional material for the coating of the base increases the cost of the materials and the manufacturing process of the known container. The object of the present invention is therefore to improve a container for fluid media of the type described in the introduction so that a predetermined quantity of smaller and qualitatively simpler material content can be used, for example a material with a modulus of low elongation, with a predetermined thickness, where an acceptable self-supporting capacity is maintained and the container can also be used preferably for large filling volumes. The object is solved according to the invention in that a) the quotient (Q) of the ratio of the filling volume of the container to the surface of the container and the ratio of the volume of a sphere to the surface of the sphere is between 0.8 and 0.85; b) the dimensions of the container are selected so that aa) A: B = 0.5 to 0.99, preferably from 0.7 to 0.95 and particularly preferably from 0.85 to 0.9; bb) ((A + B) / 2): C = 0.9 to 1.7, preferably from 0. 95 to 1.4, and particularly preferably from 1.05 to 1.25; ce) ((A + B) -C): E = 50 to 120 units in length, 2 preferably 55 to 82 units in length and particularly preferably 60 to 65 units in length; dd) F: TA + B + C] = 1 to 0, preferably 0.5 to 0.2, and particularly preferably 0.25 to 0; ee) G: A = 0 to 1.3, preferably from 1.2 to 0.8 and particularly preferably from 1.1 to 0.9; where A = front base edge of the container B = rear base edge C = side base edge E = front vertical projection F = front longitudinal edge G = rear upper edge and (A + B). C is the base surface of form 2 possibly trapezium (1) c) the elongation module is in the range of 200N to 1500N preferably mm2 mm2 200N to 750N and particularly preferably in mm2 mm ^ the range of 200N to 375N 'mm ^ mm' d) the ratio of the thickness of the container material to the bucket of the filling volume of the container is in the range of 0.000027 mm3 to dm3 dm3 0. 004 mm3 dm3 e) the overturning angle (a, ß,?) Which, when exceeded, the container turns itself over ° in the longitudinal direction and more than 8 ° in the lateral direction.

Compared with the known containers for fluid media, the novel packaging according to the invention requires significantly less material, which is also qualitatively simpler, where the ability to stay upright from the package is nevertheless comparably as good as that of the known packages. The characteristics for the solution according to the invention described hereinafter present the condition of a different design compared with the bag-type containers of known colors. In other words, a bag of known type could not be manufactured at cost and with the quality of the material used according to the invention, and would not be able to stand upright. If the characteristics for a solution according to the invention are used, a container is obtained, which is altered from its manufacturing form upon filling, but in the end guarantees the required properties of such a container, in particular a good self-supporting capacity and ease of handling. The internal pressure of the content allows the known container to assume an approximately cylindrical shape, where the material of the container can absorb the tensile stress. Characteristic a) refers to two relationships. The first relationship is the volume of filling of the container to the surface of the container; while the second relation is the volume of a sphere to the surface of a sphere. The person skilled in the art knows that on the one hand the optimization of the surface of a container is sought, which is manufactured in particular from a flexible material and changes its shape when filling and on the other hand it is desired to obtain an approximation to the relations in the case of a sphere. The teaching according to the invention proposes that to determine the quotients considered of the two relations for the container on the one hand and a sphere on the other hand naturally requires the same volume of filling. It has also been shown that the same advantageous properties can be incorporated into the package according to the invention, particularly advantageous for filling volumes of, for example, three liters or more. While the advantageous characteristic a) must be observed according to the construction described above, at the same time it is advantageous when considering package dimensions according to characteristic b), they are provided. Therefore, a theoretical packaging form in which the package has a quadratic base, preferably trapezoidal in shape, of the lateral base edges of which two side walls project so that they are in the front area must be assumed. in an upper line, that above the edge of the front base, a front wall extends towards the same upper line of the two side walls, where this same line can be configured as the front longitudinal edge. Correspondingly, a rear wall extends above the rear base edge, which extends to a rear upper edge, perpendicular to the longitudinal edge. Between this and the front longitudinal edge, an approximately triangular upper wall can also be provided. If the container is viewed from the front in a direction parallel to the plane on which the base rests, then a frontal vertical projection can be observed, that is to say an elevation of the front base edge up towards the front longitudinal edge. At the same time, from the opposite direction of observation from the rear to the rear wall, a posterior vertical projection extending from the rear base edge up towards the rear upper edge can be observed. In this theoretical model it has been assumed that both the base and the walls are flat. In this case, the front wall is preferably triangular, the rear wall may be trapezoidal or preferably triangular in shape. The long sides are called "side base edge" here, while the short sides are called front and rear base edges. Using the definitions described above, the person skilled in the art can select the dimensions of the package in the desired manner. The ratio A: B described within feature b) is always positive according to the invention, with the proviso that both A and B are greater than 0 and A is less than B. It is recognized that the trapezoidal shape of the The resulting base of this relation A: B is considered the preferred configuration. The ability to self-support is positively influenced by its dimensioning. In particular, when the container is full it tilts somewhat backwards and the emptying side of the container is almost perpendicular, that is, the height of the triangular front wall is approximately vertical. For a better understanding, it should be assumed that the flat base rests in a horizontal plane and the triangular front wall projects approximately perpendicularly, while the side walls are correspondingly inclined along the legs of the triangle of the front wall and are found in the center above the base, vertically in the upper part along the longitudinal edge. With an optimum selection according to the invention of the dimensions of the package, a use of optimized material is achieved. This means a good ratio of the surface of the container to the filling volume previously discussed in the above. When in characteristic b) the relationship of F; (A + B + C) is equal to 1, this means that the upper rear edge G is not sealed, that is to say the side walls are in the upper part along the front longitudinal edge F, which is approximately A + B longer than the lateral base edge C. When, however, at the other end this ratio is 0, this means that from the front point, ie above the front wall at the tip of the upper point of the triangle, sealing takes place to the upper rear edge. When, correspondingly, the following relation described under characteristic b), namely G: A, is particularly preferably 0, this means that the tab is not sealed. It has been shown that in this case the range in which the ratio of G: A is between 1.1 and 0.9 also produces an advantageous package geometry. In other words, the result of this and its meaning is that the triangular tabs are sealed. When the person skilled in the art considers the features according to b) of the solution, there results a self-supporting bag-type container with relatively large tipping angles. This also means that the container does not empty itself after opening the emptying means. The characteristic c) with the ranges of the elongation module means that a qualitatively simpler material can be used, which, for example has a lower elongation modulus with the predetermined thickness than the known bags made of single-layer or double-layer plastics. multilayers These ranges of the elongation module are related to the values that can be determined according to DIN 53457. Within the range of the range described above for the ratio of the thickness of the container material to the bucket of the container filling volume, it has been shown preferably with some modalities when this ratio falls in the range of 0.007 mm3- to 0.001 mm3-dm3 dm3 With slightly thicker packaging materials, the behavior of the container has proven to be particularly robust. The overturning angle according to feature e) according to the invention is the angle at which, when it is exceeded, the container is turned on itself. A higher tilting angle therefore means a good self-supporting capacity, which is obtained according to the invention despite the thin plastic film described in the above. The overturning angle is tested when the container is full. A differentiation is made here between a first overturning angle OI indicating the forward tilting of the filled container on the so-called front wall; the overturning angle ß, which indicates the lateral tilting of the container on the respective lateral base edge (either on one side or the other, the container being preferably symmetrical with respect to the longitudinal centerline of the base); and a third turning angle Y indicating the possibility of the container overturning rearwardly on the rear base edge (opposite to the overturning angle ex). The self-supporting capacity of the container according to the invention can also be defined in that the moment of self-support is greater than the moment of overturning. When the container stands "upright" in the manner defined herein, this means that at least a part of the height of the container is greater than the lengths of the edges of the base area of the container. The test procedure for establishing the respective overturning angle employs a flat table arranged horizontally on which the base of the filled container is placed. The table inclines, for example, with increasing angles and the container remains standing on the table in the inclined position. The angle increases until the container is turned over the edge of the corresponding base. Advantageously, a tilt table with an angle scale, can be used as an appropriate testing device. At present, the overturning angle is measured in the three directions perpendicular to each other, but because the lateral directions are the same due to the symmetrical construction of the package (ß angle of overturning) according to the invention only the three rollover angles a, ß and are given. In spite of a soft flexible packaging material with the properties described according to the invention, it is possible to obtain a self-supporting container for fluid media with a very low center of gravity, and it has been established that the height of fall of the container according to the invention is high compared to known containers. By means of the measures according to the invention, a single material with correspondingly good recycling properties can be used. A folding of the base is known from the general manufacture of plastic-coated paper-based liquid containers where a cross-stitched seam is provided in the base area, the ends of which form the points of the triangular flanges opposite each other with with respect to the base. These triangular tabs are folded down into the known liquid containers and fixed to the base to provide a flat, square self-supporting base for the liquid container. In the case of similar manufacturing processes for self-supporting containers according to the invention, triangular flanges adjacent to the front and / or back base edges can be provided, which can be folded down and sealed in a similar manner to the containers for known liquids. According to the invention, the containers can also be configured, however, so that the front and / or rear base edges are provided with a sealing seam. The sealing seam can be used as a dividing line, whose condition separates the triangular flange from the base and allows reworking. By means of the sealing of the triangular flange, after or even before the filling of the container, the self-supporting capacity of the novel packaging is improved. With this, it is particularly preferred when the emptying means or the flange on the side of the container when opened, is smaller than the other flange disposed on the opposite side. In this way the backward inclination of the container is obtained and the turning is avoided. At the same time, triangular tabs of different sizes can produce the trapezium shape of the base, by means of which the ability to self-support and stability can positively influence the sense described above. Furthermore, it is advantageous according to the invention, when the two side walls and also the front wall and the rear wall are joined by means of lateral base edges to the base, and when in the base a cross seal seam is applied which runs from the front base edge to the rear base edge and a superior cross seal seam at the upper ends of the side walls. In a manner similar to the theoretical package form described above, it is preferred to join the two side walls and the front and back walls to the base and provide cross-seam seams both in the bottom, in the base area and above at a distance in the area of the upper ends of the side walls. With this the sealing according to the upper cross seam, either from the front at the top point of the front surface of the triangle back to the upper rear edge or from the upper rear edge forward to where the front longitudinal edge begins . Theoretical considerations can be particularly well understood when straight cross seams are assumed. In the case of the flat base, it is clear that the bottom cross seam is naturally straight. However, the upper cross-seam seam, can be imagined with more or less long front longitudinal edges, wherein the angle at which it is placed, against the cross-seam on the base side, may be more or less acute, preferably between 0 and 30 °, particularly preferably from 5 ° to 25 °. In this case 0 ° means that the upper cross-seam runs parallel to the lower cross-seam.

When corners of different size are sealed in the base area, ie, the triangular tabs described are kept in different sizes in the direction defined above, when the emptying means is opened, the container is not emptied when the cross-seam is sealed The lower one rests parallel to the upper one. The angular positioning of the upper cross-seam with respect to the bottom seam, ie the inclination of the upper cross-seam with respect to the bottom seam, has the advantage that the volume of air in the container above the content is reduces and therefore, less content comes into direct contact with the air. With the upper cross seam inclined with respect to the base, the container can be filled to a higher level with good pouring properties. In addition, the center of gravity of the contents is advantageously diverted forward towards the front base edge and the emptying is facilitated. It is also advantageous when the upper cross-seam is composed of at least two straight and / or curved sections. With this preferred embodiment the upper cross seam seam does not run in a straight line above the entire upper area of the package but divides them into different sections. This measure allows the volume of the air head in the container to be reduced, the center of gravity to be displaced in the desired manner and also the emptying to be improved. It is also advantageous according to the invention when an upper flange formed of double material sections is attached at least on the upper cross seam, forming a handle. When the upper cross seam is placed at an angle with the lower one, during the manufacture of the container from a tube according to the invention, there remains a section of folded material that can be used as a handle and possibly reinforced with another seam. of terminal sealing. This package according to the invention would then have three crossed seams, counted from the base towards the top, ie the base, the cross-seam that delimits the side walls at the top and the one described at the end. so-called terminal sealing seam, which delimits the section of upper bent material and which will be described again later. According to the pattern of the upper end seam, it can be attached to the so-called upper cross seam that delimits the side walls at the top or can run towards it. The user can be provided with a good handle by means of a section of material formed in this way, even when the sections of material on the upper cross-seam seam are taken between the fingers only. The end seam seam that is disposed above the upper cross seam seam can be placed anywhere or in certain locations at a distance above the upper cross seam seam. In this way the section of material formed between the upper cross seam seam and the terminal seam is considered strengthened and reinforced. In this way it can be used better as a handle or to provide additional measures to form better handles. For example, according to the invention, this can be advantageous when an elongated load distribution means is set in a bent upper flange under a straight terminal sealing seam. A rod, a tube or an elongated plate can be viewed as such a load distribution means, which is placed under the upper cross seal seam, ie the terminal sealing seam and is supported therewith. In addition, to further improve a handle it can be particularly advantageous when holes or cutouts are provided at a distance from each other - similar to the arrangement of the fingers - in the upper flange according to the present invention., forming a handle. Elongated holes are known in sections of plastics per se as a handle. When, however, a plurality of holes are arranged, similar to the dispositions of the fingers of the hand in the upper flange bent under the straight terminal sealing seam, this provides a better load distribution, resulting in increased strength. to the tension of a handle manufactured in this way. By arranging the handle in the upper area of the container, it can be easier to remove it from bales, shelves or the like. When the measures according to the present invention are taken into account, it is also possible to attach the handle to the upper rear area of the container, that is to say at a distance from the emptying means, in order thereby to facilitate and improve the emptying of the contents. In addition, it is also possible to more easily connect emptying means configured differently in the front wall or at least in the front area of the container in the upper part. As a further advantage, the provision of the holes or cutouts makes the reinforcement of the material in the upper flange bent between the two upper cross seals unnecessary. By means of the arrangement of the holes similar to the fingers of the hand, the load can be distributed better on the edges of the holes. For example, it may be advantageous to configure such holes to more than 20 mm, preferably 22 mm, which results in an ergonomic arrangement and minimal material loading. When the ratio of the material of the container to the volume of filling was described above, the figures mentioned do not include the material in the area of the handle. In connection with the package according to the present invention, the handles can be configured in many ways and with the most diverse advantages. The modality with the finger holes in the bent flange ensures a better distribution of force and tensile stress in the material without a rod or the like as load distribution means. The handles can also be advantageously arranged in the area of the folded upper flange according to the invention when an upper flange is folded independently and is reinforced on the upper cross seam joining the two side walls on the upper part. by an additional terminal seam to the right of the top or if there is no such terminal seam. In each case with an upper angular cross seam, an upper flange is formed and at the same time the upper space on the content becomes narrower towards the front with the associated advantages of a better emptying, the distribution of the center of gravity, between others The most important advantage, however, is the improvement in the self-supporting capacity and considerably less costs for the material when the measures according to the invention are taken into account. Additional advantages, features and possibilities for the application of the present invention will be shown in the following description of the preferred embodiments together with the accompanying drawings. These are shown in: Figure 1 is a theoretical model of a container with an accurate representation of various edges and walls, Figure 2 is a modality, similar to Figure 1 but more specific, a container for fluid media with seams of sealing, Figures 3-5 other additional embodiments of the containers for fluid media, in which the upper cross seam is placed at different angles with the terminal seam, Figure 6 is a perspective, schematic view of an additional embodiment of the container for fluid media according to the invention, in which, however, an elongated tube is fitted above the terminal seal seam as a load distribution means.

Figures 7-9 are similar diagrams as those of Figure 6, where the grip is reproduced by holes in the upper bent flange, Figures 10-12 are schematic views of a typical container for fluid media, in which the angle of respective overturning is shown during the measurement, Figure 13 is a perspective of a container filled with fluid media with a handle and bent, triangular flanges. Figure 1 shows a theoretical or ideal example of a self-supporting container for fluid media with straight edges and flat walls. The base 1 is flat and is designed resting on a flat horizontal support. It is delimited by a front base edge A, a rear base edge B and two lateral base edges, of which the one facing the front is marked C. Two side walls 2 and 2 'are joined above the sides. two lateral base edges C to base 1, which touches at the top along the front longitudinal edge F above the central longitudinal center line 3 of the base. Additionally, a front wall 4 and a rear wall 5 are joined to the base above the front base edge A and the rear base edge B. The foot of the front vertical projection E is located where the longitudinal center line 3 of the base 1 intersects the front base edge A. The upper terminal point of this front vertical elevation E is marked 6 and represents the point of the equilateral triangle of the front wall 4, from which the front longitudinal edge F extends backwards , parallel to the side base edge C to point 7. The distance between points 6 and 7 thus represents the length of the front longitudinal edge F. In a similar manner when viewed perpendicularly from behind towards the rear wall 5, you can see the vertical posterior projection D, which reproduces the vertical distance apart from the two lines B that run parallel to each other, ie the posterior base edge and G, is say the upper back edge. It can be seen that in the embodiment of Figures 1 and 2, the rear upper edge G is greater than 0, ie the rear wall 5 is trapezoidal in shape and a triangular surface 8 extends between the rear terminal point of the longitudinal edge front F and upper rear edge G. If the length of the upper rear edge G is 0, then the upper triangular surface 8 disappears and the rear wall 5 is an equilateral triangle. In various modalities, in particular in the case of the modalities illustrated in Figures 3 to 13, the upper posterior edge G is eliminated, therefore G = 0. The relation G: A is then also 0. This is a practical modality preferred that shows many positive properties. A common plane can be conceived, running along the front base edge A and the rear upper edge G, which then, in the case of the embodiments of Figures 1 and 2, divides the container into two geometric bodies, that is to say a wedge inclined with the base 1 and an inclined pyramid with the front wall 4 and the triangular surface 8. The total volume of this container can also be considered as the sum of the wedge described and the pyramid. In all the modalities the emptying means, not described in more detail, are marked with 9. This can be provided with either a separation flange (Figures 2 to 5) or a screw cap (Figures 6 to 9 and 13) or with other means such as, for example, cutouts or markings, on which the basic idea of the invention does not depend. The basic figure shown in Figure 1 is represented somewhat more concretely in Figure 2 as a container for fluid media with sealing seams. In particular, a sealing seam 10 runs along the front base edge A, and a sealing seam 11 parallel thereto at the rear base edge B. Both are crossed by a longitudinal center seam 12 which runs parallel to the longitudinal center line 3 in the base 1. While the front wall 4 is smooth and the pouring means 9 is only provided in the upper area, a sealing seam 13 passes through the rear wall 5. Along the upper rear edge G there runs an additional sealing seam 14 which rests parallel to the sealing seam 11 and is crossed by an upper cross seam 15 which begins at the upper rear edge G, passes through the top wall 8 and the height of an equilateral triangle to the rear end point 7 and then extending at an angle along the front longitudinal edge F to the front shearing 6. Although in the case of the according to Figures 2 to 5, the front base edge A is provided with a sealing seam 10 and the rear base edge B with a sealing seam 11, without representing the triangular flanges, the embodiment of Figure 8 shows two rectangular tabs 16 which are not sealed although two sealing seams 10 and 11 are provided. Along the latter the triangular tabs 16 are simply folded down and fixed to the base 1 so that the container in Figure 8 is again capable of self-support. When the cross seam 15 runs straight or with a bend from the front corner 6 to the front wall 4 upwards to the rear corner 17, which should be understood as being approximately indicated as the rear upper edge G has become 0 , the embodiments are produced as shown in Figures 3 to 9 and 13. In Figures 3 and 5 the upper cross seal seam 15 runs first along the front longitudinal edge F towards the rear end point 7 thereof. and then it is bent at an angle not equal to 0 towards the longitudinal seal seam 12 in the base 1. The cross seal seam as a set designated 15 is in this case composed of a straight part section 15a that provides the longitudinal edge front F and the rear angled part section 15b terminating at the rear end point 17. As above, the upper cross seal seam 15 extends, however, as in the case of another. as modalities, from the front upper end point 6 to the rear end point 17, thereby limiting the filling volume of the container. In the embodiment according to Figures 4 and 6 an upper flange 18 formed of a section of folded material is fixed above the upper cross seal seam 15 as a whole, which can be used as a handle 19. With the others according to Figures 3, 5 and 6 a bent flange 18 is formed above the section of part 15b of the upper cross seam 15. If the material sections of the side walls 2 and 2 'are left without cutting and extending above the section of the part 15b of the upper cross seal seam 15, the upper flange 18 is formed made of sections of folded material. This upper flange 18 can now be reinforced in that an additional sealing seam, ie the end seal seam 20 is applied at a distance above the upper cross seal seam 15. When in addition the rear edge of the flange bent upper 18 is sealed, this means that with reinforcement stitching 21, additional stiffness is provided. In other words, in the embodiments according to Figures 3 and 5 of the upper bent flange 18 bordered by three sealing seams in a triangle, i.e. the section of part 15b of the cross-seam 15 and the sealing seams 20 and 21 finally described, which in this case are perpendicular to each other. Also in the embodiment of Figure 4, the upper flange 18 is triangular with the upper cross seal seam 15 as the hypotenuse and the sealing seams 20 and 21 which are perpendicular to each other. This triangular flange can be used in each case as a handle for the supported emptying. The relationships in Figures 6 to 9 with respect to the triangular flange 18 are the same. However, in the embodiment of Figure 6, an elongated tube 22 is placed on top of the folded upper flange 22 above the straight terminal sealing seam 20 in a support section 23 made of plastic material bent and retained by means of a additional retaining sealing seam 24 disposed above the upper terminal sealing seam 20. It is understood that the handle of a tube 22 provides an improvement and further facilitates emptying. In the embodiment according to Figures 7 to 9 and 13, the holes 25 are arranged at a separate distance in the upper flange 18 forming the handle designated as a whole 19, which could, however, also be replaced by a cut in shape U. According to Figure 4 this refers to four trades 25, which are provided in configuration and arrangement in a manner similar to that of the fingers of a hand on the tab 18. In the embodiment of Figure 8, the four holes 25 are replaced by an elongated hole 25a, and in the embodiment of Figure 9 in the case of the handle 19 by two elongated holes 25a arranged at a slight angle with an easy grip manner. Two elongated holes 25a are also shown in Figure 13 in the folded tab 18 resembling a strip. This is delimited at the top by the terminal seal seam 20 and at the base by the upper cross seam seam 15. The latter is divided into a front section 15a of curve and two back sections 15b slightly curved. In this embodiment of Figure 13, in the lower area the triangular flanges without sealing seams, folded down and fixed to the base 1 are shown. When Figure 11 is considered, the longitudinal direction 26 of the container is observed, which is reproduced by the arrow pointing to the left towards the front wall 4 in Figure 10. An inclination table 28 is placed on a horizontal support 27 and is tilted in the manner shown with respect to the horizontal support 27. In the In the case of Figure 10, the filled package is inclined towards the front base edge A in the direction of the curved arrow 29 so that the base 1 together with the inclined table 28 assumes the angle a with respect to the support 27. If the container remains standing without turning, the angle a increases until the angular limit is reached, the so-called tipping angle. In the opposite direction, according to Figure 12, the inclined table 28 tilts back around the rear base edge B in the direction of the curved arrow 30 so that the base 1 and with it the inclined table 8 assume the angle Y with respect to the horizontal support 27. Also in this case, the process is carried out in the manner described above and it is determined whether the package is stopped or turned at the selected angle 7. The lateral overturning is determined according to Figure 11, which is the same in one direction as in the opposite direction, since the container is constructed symmetrically with respect to the longitudinal centerline 3. Also in this case, the inclination table 28 is inclined at an angle in which, it presses the lateral sides for the lateral emptying according to the curved arrow 31 and this is the lateral emptying angle β.
