Description

  The present invention relates to a packaging container according to the upper conceptual part of claim 1.

  Such packaging containers are widespread as horizontal gusset bags or bottom gusset bags and not only provide low packaging consumption in terms of space, volume and cost, but are also efficient with sufficiently improved machine throughput. Well manufactured, filled and closed. However, the cuboid shape that is generally desired for storage, shipping and display of goods (packed) can only be formed roughly in the case of conventional packages. This is because, as a precondition, the rectangular parallelepiped shape requires complete filling that is difficult to achieve, and in the case of a flowable packaging article, a slight deformation occurs as a whole. As is conventional, the package is joined at one (top) end, possibly also gathering lateral gussets, to form a take-off opening, and in some cases the other end is also bottom side When the intermediate transverse seam forms a closure, the shape of the package tends to change due to insufficient filling. In this case, the package cannot reliably stand up (independent). In addition, the take-out slit is short and, in some cases, also provides good access to the interior of the package via a take-out opening with a reseal device as long as it is obstructed by a lateral gusset in the upper closure. It is not possible.

  Deployable in a substantially rectangular parallelepiped shape, which is provided between the two main walls forming an intermediate seam or strip, in particular a bottom seam or an upper strip, gathering together at the ends located on opposite sides However, a packaging container as described above having a lateral gusset wall that terminates in a town is disclosed in, for example, German Patent Application Publication No. 102008011471, US Pat. No. 6,481,183, and US Pat. No. 6,874,935. U.S. Pat. No. 7,396,163, U.S. Patent Application Publication No. 2006/0189467 and JP-A-03-240650. A packaging container with a bottom gusset wall and an upper strip formed with a reseal device is evident from EP-A-1266836. German Offenlegungsschrift 103 160 65 describes a method for different packaging containers. These packaging containers each have two folds (folds) positioned side by side on one wall. Of these rods, one rod forms an opening indicator connected to the closure device. However, this leads to troublesome and complex end / transition areas in the shape of the container.

  The object of the present invention is not only to allow a better filling degree in bulk or flowable articles, but also to be able to stand up better at the side walls or end walls and possible by means of a resealing device. It is to provide a packaging container which can be brought closer to the desired rectangular parallelepiped shape which allows a take-out opening which is accessible as sufficiently and comfortably as possible.

  This problem is solved by the features described in the characterizing portion of claim 1, starting from the packaging container described in the superordinate conceptual portion of claim 1.

  According to the present invention, the main step for solving the aforementioned problem is that the extraction opening extends along one longitudinal edge of the plurality of longitudinal edges. In the present invention, the position of the take-out opening that has been conventionally disposed in the upper closing portion of the packaging container in terms of manufacturing technology is changed to one of the plurality of longitudinal edges. This longitudinal edge allows a larger or longer infusion / extraction opening that can also be fully and comfortably opened from the edge length. In addition, this region of the packaging container can be easily moved away from the connecting portion or closing portion of the horizontal gusset wall as in the conventional case, and in this case, it can be passed without difficulty without being obstructed. In particular, by repositioning the extraction opening at the side edge and away from the middle region of the container wall, the adjacent walls of the container can be bent and spread almost flat when opened, correspondingly. And almost no place. This is also true when a rectangular parallelepiped packaging container with edge lengths that are not so different is desired to be sufficiently closer, for example, to a cubic shape. Also, due to the free configurability achieved by changing the position of the extraction opening to the side edge, a better filling of the packaging container will result in a more accurate cuboid shape and one side wall or one end wall. This is possible with the advantage of being able to stand up.

  For this purpose, it is not necessary in the present invention for the extraction openings extending “along” along one longitudinal edge to be provided exactly symmetrically on the longitudinal edge. On the contrary, the structure of the resealing device makes it possible to provide this resealing device directly adjacent to one or the other wall (main wall or side wall).

  Preferably, the reseal device is formed with two reseal strips. Both re-seal strips have a joint that is irreversibly cut open when first opened. This has the advantage of a “new warranty” in sales and intact delivery, which is sufficient in the sale of packages and also provided by commercially available resealers. Furthermore, in this way, the reseal strip can be additionally protected against breakage when the packaging container is specially loaded, in particular during shipping and sales. The resealing device with two reseal strips can be opened and closed using profile strips that are locked together and possibly a longitudinally movable slider. Safety can be ensured by a simple coupling part and sealing can be performed. However, until the first opening, the reseal strips may be joined together via a peelable (removable) film web. This film web allows the first opening without tools.

  An empty, and thus packaging bag, which is filled for the first time, may preferably have a wide injection opening which is closed after filling. According to the present invention, this injection opening is not provided adjacent to the resealing device directly in line with the extraction opening as is conventional, but better one of the other longitudinal edges. Or one of the lateral edges. This makes it possible for the first time after filling, for example, to form a filling opening which is closed by a sealing seam, for example, which is wide and well accessible irrespective of the withdrawal opening and the resealing device. This allows not only comfortable filling, but also a high degree of filling. This degree of filling can be improved to a residual volume well below 5% instead of the conventional 10% to 15%. Depending on the mechanical filling situation, it is advantageous for the injection opening to be formed first by an overhanging injection tube piece that can be comfortably closed and separated by a separating and sealing seam after filling. Such an injection tube piece can be formed, for example, by an excess film area of adjacent walls. The film regions are drawn out as strips in contact with each other and are joined together on the edge side to form a tube shape.

  In particular, the packaging container according to the present invention may be provided with at least one grip as long as the packaging container as contemplated in the present invention exceeds the “hand-held” dimensions due to its large volume. . This grip can advantageously be folded flat with the packaging container. Such a grip is advantageous not only for the purchaser's handling when carrying the filled packaging container home, but also for lifting one side of the extraction opening through the grip when opened. It becomes. The grip may be a strip formed from a film. This strip is fixed in a flat state on one wall. For pulling up, the grips may be placed on one wall at a set distance from the reseal device.

  In order to avoid structures with intermediate lateral seals or lateral seams at the top and possibly the bottom, which were certainly easy in the past, but disadvantageous especially in the filled state The packaging container according to the present invention can acquire a strictly geometric structure. In this structure, the sealing seam extends only generally at the edge between the walls. This provides an originally set cuboid shape that cannot be initially obtained with proper and sufficient filling. Preferably, a tube shape is formed, for example a blow film extruded into a tube, but more generally a tube shape consisting of a flat film formed into a tube by one longitudinal seam. The tube-shaped open end cross-section is located at a suitable distance from the rectangular parallelepiped shape and is closed by end walls via edge seams.

  A longitudinal seam for the tube can advantageously be provided at the edge. However, the tube shape can also be obtained by individual walls, for example the main wall and the side walls, being sealed together by four side seams forming a longitudinal edge. The longitudinal seam contributes to reinforcing the edge to form a cuboid shape.

  The packaging containers described above show their particular advantages in larger containers where an improved degree of filling and a more accurate cuboid shape are particularly advantageously applied. This container can be formed with reduced material consumption with respect to the packaging volume, and can be transported and stored with very low loss space consumption, especially when standing on a side wall (“ Horizontally ”) or standing on one end wall (“ vertical ”) and directing the main wall to the purchaser can be effectively displayed on the sales shelf. The provided display space, for example, the depth of the sales shelf, can be utilized by the fact that the package is located one after the other.

It is a perspective view of the packaging container which concerns on this invention in the filled state. It is the figure which looked at the packaging container shown in FIG. 1 with which it filled and was open | released in the extraction opening from the back side. It is a figure which shows the packaging container which concerns on 2nd Embodiment in the folded state. FIG. 4 is a perspective view of the packaging container shown in FIG. 3 in a developed state for filling. It is a perspective view of another packaging container in the folded state. FIG. 6 is a perspective view of the packaging container shown in FIG. 5 in a developed state for filling.

  Four embodiments for the subject of the invention are shown in the drawings and are described in detail below.

  The packaging container generally indicated by reference numeral 1 in FIG. 1 has a rectangular parallelepiped shape according to the drawing (and close to actual use). This rectangular parallelepiped shape includes three pairs of rectangular parallelepiped surfaces that face each other. These rectangular parallelepiped surfaces are typically formed in different sizes for each pair. The packaging container 1 is manufactured from a film material. This film material can be sealed at least on the inside, i.e. has at least the inside a plastic material that can be sealed. Although the film material may be uniform throughout, it may have a laminate made of plastic material or metal material, which makes it possible for moisture resistance, vapor permeability, fragrance retention, tear strength, etc. Different requirements are imposed on the packaging.

  The walls that are combined to form a rectangular parallelepiped shape are referred to as main walls 2 and 3, side walls 4, and end walls 5 depending on the size. The main walls 2, 3 and the side wall 4 are delimited from one another by longitudinal edges 6, 7, 8, 9 respectively. The longitudinal edges 6, 7, 8, and 9 also uniformly form the longest edge of the rectangular parallelepiped. Although the remaining edges surrounding the end wall 5 can be divided into two different lengths, they are collectively shown as 10, 11, 12, 13, 14, 15, 16 as lateral edges in the drawing. It is.

  In FIG. 1, the alternate long and short dash line 17 is also written in part on the side wall 4 and the end wall 5 in parallel to the main surfaces 2 and 3, and in part inwardly from the corners in the plane. It is written to extend. The dashed-dotted line 17 is simply flat when the packaging container 1 is provided with the side walls 4 and end walls 5 folded in a V shape and the main walls 2 and 3 positioned so as to overlap each other flatly (in a state ready for shipment). ) A fold line or fold when folded. An intermediate line extending parallel to the main walls 2 and 3 represents an original fold line. The diagonally extending line indicates that the V-folding in the corner area can only be performed on one side to the edge, whereas the other side folding is adapted via a triangular back fold. Indicates that it must be.

  However, the illustrated packaging container 1 does not have an intermediate seam as a whole. This intermediate seam is common in conventional horizontal or bottom gusset bags due to manufacturing technology and is a disadvantageous transition when combining the main and side surfaces to form the only seam for a cuboid shape. I will provide a. In this embodiment, the film pieces that form a square wall are joined together via a sealing seam that extends along all longitudinal and lateral edges.

  Of course, the rectangular parallelepiped shape can also be formed by, for example, a film piece. This piece of film forms the main surface 2, 3 and the side surface 4 in one piece and is joined only at one longitudinal edge, eg the longitudinal edge 6, to form a tube shape and then open The tube end is closed by the end wall 5. However, in the illustrated embodiment which is cumbersome, the longitudinal edge seam, which should be saved in some cases in terms of manufacturing technology, clearly stands out and reinforces the longitudinal edge, thereby creating a rectangular parallelepiped shape. It also has the advantage of better formation.

  The longitudinal edge 6 can be completely or at least fully opened by the resealing device 18. In this respect, a reseal device 18 is sealed between the main wall 3 and the side wall 4 instead of the sealing seam. The arrangement of the resealing device 18 along one longitudinal edge, in this embodiment along the longitudinal edge 6, is adjacent to each other so that a large opening is possible and a large area is obtained upon removal. The wall can be moved away from each other, and has the general advantage that a sliding surface is formed by the inner surface of adjacent walls upon outflow through the extraction opening.

  Further, a grip 19 is disposed at the approximate center of the side wall 4. This grip 19 makes it possible to handle a particularly bulky packaging container 1. By placing the grip 19 on the side wall 4 (instead of one of the main walls 2; 3), a carrying position with little overhanging to the side is achieved. The grip 19 may be formed according to one embodiment described in, for example, International Publication No. 2005011221, as in the related art. In the arrangement form provided in the same number, the grip 19 is not only formed flat on one of the intermediate fold lines but also foldable along the fold line. Yes. This configuration has a flat grip band 20 that can be gripped from below at the center. The grip band 20 is sealed to the support plate 21 toward the end. The support plate 21 itself is further fixed to the sealing film 22 in order to transfer the load applied to the thinner film on the side wall 4. However, the grip 19 serves not only for transporting the (filled) package, but also as an operation part at the time of opening as shown in FIG. The side wall 4 can be pulled up by the grip 19, which allows access to the packing of the packaged product when the resealer 18 is opened. However, especially in the case of packaging fillings where contact by hand must be avoided, the opening via the grip 19 and the removal using the tool (spoon) 23 can be performed.

  Reseal device 18 is, in the form shown, a "slider" fastener that is conventional in film packaging, i.e. a fastener available as off-the-shelf with two profiled strips that can be locked in and out of each other in the longitudinal direction. It is formed as. In this slider fastener, the locking is additionally facilitated by the slider 18a. As is well known, the profile strip is provided with a connection tag (not shown) made of plastic. With this connection tag, the deformed strip can be sealed in the film package as in the present embodiment. The connection tags are also coupled to each other. As a result, the resealing device 18 is closed regardless of the displacement of the slider 18a, and the sealing property of the packaging container 1, for example, a state filled with the external pressure applied to the packaging container 1 during transportation is ensured. Yes.

  The coupling part of the connection tag can be cleaved or cut open in a conventional manner, which also makes it possible to recognize the first opening of the packaging container 1. An alternative solution in the present invention for separating the reseal strip or connection tag is to form the joint in the form of a strip that can be pulled up (removable), so that during the separation. No tools are required.

  The packaging container 1 has advantages relating to the full use of the transport space, the storage space and the exhibition space due to its particularly precise rectangular parallelepiped shape. The packaging container 1 can stand on a sales shelf at the position shown in FIG. 1 (having a desired packaged shape) having, for example, an upper grip 19 and a main surface 2 that can be recognized directly, Furthermore, in order to take advantage of the depth of this shelf, it is also possible to cover up another similar package located in parallel behind it.

  A high degree of filling is important for an accurate cuboid shape. However, this filling at the same time again leads to minimal packaging when the amount of product to be packaged is set. An advantageous injection opening can be provided for filling. This injection opening is desirably large enough for quick mechanical filling and allows access to the filling to all corners of the packaging container 1.

  FIG. 3 shows another packaging container 24 in a folded state. The packaging container 24 shows a main wall 25 having a longitudinal edge 26 and a reseal device 27 provided on the longitudinal edge 26. An injection opening 28 is formed with a tube piece 29 projecting upward beyond the original main wall 25. The configuration of the packaging container 24 in the unfolded state is shown in FIG. In FIG. 4, the side wall 30 and the end wall 31 are developed adjacent to the main wall 25. The pipe piece 29 projecting upward beyond the original main wall 25 and the end wall 31 is formed on the one hand by the surplus of the film material of the main wall 25, and on the other hand, the film material of the end wall 31. It is formed by surplus. Both surpluses are sealed with an extension of the longitudinal edge and thus provide an injection opening 28 that extends over the entire width of the main wall 25. Thereby, the packaging container 24 can be satisfactorily and sufficiently filled with, for example, a fluid material. At this time, the packaging container 24 filled with the fluid material is further inclined so that the end wall 31 is separated from the tube piece 29, and the lower side of the end wall 31 is completely filled when filling. It may be tilted so that After filling, the tube piece portion 29 can be cut off, for example with a sealing separation seam. At that time, the injection opening 28 is also closed.

  5 and 6 show the packaging container 32 slightly modified with respect to the packaging container 24 in a folded form (see FIG. 5) or an unfolded form (see FIG. 6). The packaging container 32 includes a front main wall 33, an end wall 34, and an injection opening 35 provided in the tube piece 36. In this embodiment as well as in the packaging container 24, the reseal device 37 is arranged at one longitudinal edge, whereas the injection opening 35 is, for example, a conventional transverse gusset bag often equipped with a reseal device. It is not provided directly in the resealing device as described above, but is provided on another surface or edge. In the packaging container 24, the injection opening 28 was provided at one lateral edge, whereas in the embodiment of the packaging container 32 shown in FIGS. Is provided in the middle of the end wall 34. Also in this embodiment, the injection tube piece 36 is made of an adjacent wall, i.e., an overhanging film material of the end wall 34 in this embodiment. The end wall 34 is formed from two halves, between which the overhanging film material is bonded and sealed on the edge side. The arrangement of the tube piece 36 in the middle serves for better filling possibilities in the upper corner area, especially during mechanical filling which is performed without tilting the packaging container.
