Description

  The present invention relates to a stand (self-supporting aid) for holding a bag container (pouch container) formed by welding a spout on a bag in an upright state.

  In recent years, bag containers having a structure in which a spout is welded to a bag manufactured using a laminated sheet (film) as a raw material have been widely used in various fields. More specifically, this bag container has a flexible bag provided with an opening at the upper end, an intrusion part that has entered the bag from the opening part, and an exposed part located outside the bag, and An intrusion portion is provided with a spout welded to the bag, and a neck portion is formed in a portion of the exposed portion of the spout close to the bag. The bag is manufactured by putting the front and back sheets (and bottom sheet) on top of each other and wearing the surroundings. For this reason, the upper end of the bag is elongated on both sides of the spout in a plan view, filling the contents Before doing so, the bag is flat. Thus, the bag has a wide front and back.

  This bag container has advantages such as lower manufacturing costs and transportation costs compared to resin and glass bottles, an advantage of reducing the volume after disposal, and low incineration calories. However, there is a problem that the bag is inferior in its independence because it is flexible and does not have rigidity. In particular, for example, those with capacities exceeding 500 cc and those with a height higher than the bottom area have a problem that the low self-supporting property is prominent, and the neck breakage phenomenon (or bowing phenomenon) occurs frequently. .

  Therefore, various stands (auxiliary tools) for holding the bag container in a standing state have been proposed. This stand is roughly divided into wire-made products, resin-molded products (injection-molded products), and assembly-type products made of sheets. There is an advantage that it can be manufactured as a material at low cost.

  Patent documents 1 and 2 are mentioned as a concrete prior art of a sheet-made assembly type stand. Among these, Patent Literature 1 discloses a top portion having a hole into which a neck portion of a spout in a bag is fitted, a front portion integrally connected to a front end edge of the top portion, a back portion integrally connected to a rear end edge of the top portion, and a front surface. A pair of bottom portions continuous to the lower end of the portion and the lower end of the back surface portion are provided, and the assembled state is maintained by overlapping and bonding the two bottom portions. Moreover, in this patent document 1, the front-back width | variety of a bottom part is larger than the front-back width | variety of a top part, Therefore, in the assembled state, it is trapezoidal by the side view.

On the other hand, Patent Document 2 includes a side plate positioned on the side of the bag, the front plate is continuous with the front end of the side plate, the back plate is continuous with the rear end of the side plate, and the front plate The top plate overlapped with each other at the upper end of the back plate and the upper end of the back plate are continuous, and a recess that fits into the neck portion of the spout in the bag container is formed on the pair of top plate so as to face each other.
JP 2005-329955 A Japanese Utility Model Publication No. 6-54543 CD-ROM (particularly FIG. 1)

  Assembly-type stands are often disposable. Therefore, it is preferable to manufacture inexpensive sheet materials such as resin-laminated paper and resin sheets from the standpoints of manufacturing cost and ease of disposal. It is also necessary to ensure a certain degree of rigidity in the state of being. In particular, when the capacity of the bag container is about 1 liter, considerable rigidity (strength) is required. However, since Patent Documents 1 and 2 have one or both of the left and right sides open, there is a risk that it will be difficult to secure the required rigidity if an inexpensive sheet material is used. If it is a molded product, the cost increases.

  The present invention has been made to improve the current situation.

  The bag container attached to the stand according to the present invention is the same as the conventional bag, a flexible bag having an opening at the upper end, and an intrusion part that enters the bag from the opening and an exposed part located outside the bag. And the intrusion portion is welded to the bag, a neck portion is formed in a portion of the exposed portion of the spout adjacent to the bag, and the bag The upper end is elongated in both sides with the spout in plan view, and the bag is flat before filling with the contents, and therefore the bag has a front surface and a back surface.

  And the stand which concerns on invention of Claim 1 is located in the back board of the upper board which has a suspension board hole in which the neck part of the spout in the said bag container fits, the front board located in front of the said bag, and the said bag A back plate, left and right side plates positioned on the left and right outer sides of the bag, and a bottom plate positioned below the bag, and adjacent plates are connected through a common side fold. A holding means is provided that can be developed as a whole and holds the bag in an assembled state in which the bag is suspended.

  The stand according to the invention of claim 2 is the stand according to claim 1, wherein either one or both of the front plate and the back plate are separated from each other in the deployed state and overlap each other in the assembled state. It consists of

  The stand according to the invention of claim 3 is the stand according to claim 1 or 2, wherein the front plate is a first front plate that is continuous with the front end of the upper plate and a second front plate that is continuous with the longitudinal side end of one side plate. The upper end of the back plate is continuous with the upper plate, the left side plate is continuous with the left end of the back plate, and the right side plate is continuous with the right end of the back plate. The bottom plate is continuous with the lower end of the back plate, the lower end of the second front plate, or the lower end of one of the left and right side plates.

  In the present invention, the names of the front plate and the back plate are for convenience, and there is a case where there is no distinction between the front and the back in an actual product, and the terminology of the back plate should be used. It is also possible to have two front plates before and after. The difference between the left and right side plates is the same.

  The stand according to the present invention has an upper plate, a front plate, a back plate, left and right side plates, and a bottom plate in an assembled state and surrounds the entire bag container, and is therefore manufactured using an inexpensive material. However, high rigidity can be ensured in the assembled state. For this reason, a bag container with a large capacity can be supported accurately. In particular, in the configuration of claim 2, higher rigidity can be ensured by the presence of the two front plates or back plates.

  The stand of the present invention is manufactured in an unfolded state by punching or folding a single material sheet using a device such as Thomson, and a fold portion on one side where adjacent plates are in common Is continuous. And there is no limitation on the back plates 1 and 2 as to which plates are continuous with each other, but if the configuration of claim 3 is adopted, the back plate, the left and right side plates, and the second front plate are continuous in series. Therefore, there is an advantage that the cost of the material sheet can be suppressed by reducing the loss of the material sheet as much as possible.

  In addition, since the bag container has a bulky shape with a large height with respect to the width, a stand is necessary, and thus the left and right side plates, the front plate and the back plate are generally long in the vertical direction. If the structure of 3 is employ | adopted, since the 2nd front board is continuing to the vertically long side edge extended long up and down among one side boards, the connection strength of a 2nd front board and one side board is high, As a result, a stand The rigidity can be further improved.

  Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 4 show the first embodiment. 1A is a perspective view of the bag container 1 in a state where the contents are filled, FIG. 1B is a perspective view of the stand 10 in an assembled state, and FIG. 1C is a CC view of FIG. Sectional view, (D) is a sectional view taken along the line DD of (C), FIG. 2 is a developed view of the stand 10, FIG. 3A is a perspective view showing a state in the middle of assembly, and FIG. FIG. 4 is a plan view showing the manufacturing process, and FIG.

(1) Structure of bag container Prior to the description of the stand 11, the bag container 1 will be briefly described. The bag container 1 includes a bag 2 and a spout 3. The bag 2 is composed of a front sheet, a back sheet, and a bottom sheet, and a shoulder 2a as an upper end extends linearly on both sides of the spout 3. Needless to say, the bag 2 is manufactured in a flat state. In the present application, as indicated by arrows in FIG. 1 (A), the front / rear / left / right wording is used by defining a state facing one wide surface in the bag container 1 as a front view. An opening 2 b is provided in the left and right middle portion of the upper end portion of the bag 2.

  The spout 3 of the bag container 1 includes a main body 4 and a screw-type cap 5. The main body 4 includes an intrusion portion 4 a that enters the opening 2 b of the bag 2 and an exposed portion 4 b that is positioned outside the bag 2. have. A PP band 6 connected via a bridge is integrally connected to the lower end of the cap 5. Moreover, the intrusion part 4a of the main body 4 in the spout 3 has a substantially eyeball shape that is long in the left and right in a plan view. On the other hand, the exposed portion 4b of the main body 4 in the spout 3 includes a substantially rectangular neck portion 7, a flange 8 continuous with the upper end thereof, and a mouth portion (shown explicitly) above the flange 8 as shown in FIG. And the cap 5 is screwed into a male screw formed in the mouth portion.

  The flange 8 of the main body 4 has a larger diameter than the circumscribed circle of the neck portion 7, and the intrusion portion 4 a of the main body 4 is larger than that of the neck portion 7 in both the front-rear width and the left-right width. Accordingly, the neck portion 7 is formed in a groove shape in the main body 4, and the posture is maintained by fitting the neck portion 7 into a jig in the content filling step.

(2). Stand Structure Next, the structure of the stand 11 will be described. As can be easily understood from FIGS. 1 and 3, the stand 11 includes an upper plate 13 having a suspension support hole 12 into which the neck portion 7 of the spout 3 in the bag container 1 is fitted, and a first and a second plate located in front of the bag 2. Second front plates 14 and 15, a back plate 16 located on the back side of the bag 2, a left side plate 17 and a right side plate 18 located on the left and right outside of the bag 2, and a bottom plate 19 located below the bag 2 have. In the description of the board, front / rear / up / down / left / right terms are used based on the state after assembly.

  The suspension support hole 12 is a quadrangle that fits tightly into the neck portion 7 of the bag container 1, and by forming cuts 20 a extending radially from the corner portion of the suspension support hole 12 in the upper plate 12, The four portions are formed with the elastic support piece 20, and the cap 4 can be inserted into the suspension support hole 12 by deforming the elastic support piece 20. The bag container 1 is suspended in a standing posture by the flange 8 being supported by the upper plate 13.

  The front-rear width dimension of the upper plate 13 is set to the same size as the outer diameter of the cap 4 (and the flange 8) (the front-rear width dimension of the upper plate 13 is preferably as small as possible). In addition, the specific form of the notch 19 and the elastic support piece 20 is not limited to what is illustrated, and various things can be employ | adopted.

  The bag container 1 has a shape that is long in the vertical direction. Therefore, the front plates 14 and 15, the back plate 16, and the left and right side plates 17 and 18 are vertically long and large in height with respect to the lateral width. 18 has a trapezoidal shape (lower spread) in which the front-rear width gradually increases from the upper end toward the lower end. In this way, the left and right side plates 17 and 18 are formed so as to extend downward in accordance with the form of the bag container 1 after filling the contents.

  When the cap 4 is rotated during opening or sealing, it is necessary to keep the bag container 1 in a non-rotating state. However, the width dimension of the upper end portions (or the upper plate 13) of the side plates 17 and 18 is made as small as possible. Thus, the upper portion of the bag 2 can be reliably pressed through the front plates 14 and 15 and the back plate 16, and the bag container 1 can be securely held in a state where it is not rotated during opening and sealing.

  As shown in FIGS. 2 and 3, the first front plate 14 is integrally connected to the front end edge of the upper plate 13 via the first fold line 21, and the back plate 16 is connected to the rear end edge of the upper plate 13 with the second fold line 22. The left side plate 17 is integrally connected to the left end of the back plate 16 via a third fold 23, and the right side plate 18 is integrally connected to the right end of the back plate 16 via a fourth fold 24. The second front plate 15 is integrally connected to the front end of the left side plate 17 via a fifth fold 25 and the bottom plate 19 is connected to the lower end of the back plate 16 via a sixth fold 26.

  An upper auxiliary piece 17 having a slightly smaller front-rear width dimension than the front-rear width of the upper plate 13 is integrally connected to the upper ends of the left right-side plates 17, 18 via a seventh fold 28. A lower auxiliary piece 29 having a front-rear width dimension of about half of the front-rear width of the bottom plate 19 is integrally connected via an eighth fold 30. Further, a narrow front auxiliary piece 31 is integrally connected to the front end of the right side plate 18 via a ninth fold line 32, and a narrow lower auxiliary piece 33 forms a tenth fold line 34 at the front end of the bottom plate 19. Are connected together.

  The upper auxiliary piece 27 has substantially the same longitudinal dimension as the front and rear width dimensions of the upper ends of the side plates 17 and 18, and the lower auxiliary piece 29 has substantially the same longitudinal dimension as the front and rear width dimensions of the lower ends of the side plates 17 and 18. The auxiliary piece 31 has substantially the same length as the vertical length of the right side plate 18, and the lower holding piece 33 has substantially the same left and right length as the horizontal width dimension of the bottom plate 19. In FIG. 2, each crease is indicated by a dotted line, but this does not mean a sewing line (the crease can also be configured by a sewing line).

  As a holding means for holding the stand 11 in the assembled state, in the present embodiment, a first locking piece 35 is provided at the lower end of the first front plate 14 and a first engagement hole 36 is formed at the base of the lower auxiliary piece 37. A second locking piece 37 is projected from the right end (free end) of the second front plate 15 to form a second engagement hole 38 at the base of the front auxiliary piece 31.

  Each locking piece 35, 37 is connected via a crease 39, and the locking pieces 35, 37 are formed in a large diameter shape (tapered shape) with a narrow tip and a large width dimension toward the root. In addition, the base portion is a constricted portion with a narrow interval. And the constriction part of the locking pieces 35 and 37 is set so that it may fit into the engagement holes 36 and 38 exactly. That is, the locking pieces 35 and 37 and the engaging holes 36 and 38 are fitted together by slightly elastically deforming the material.

  In the present embodiment, one set of the first locking piece 35 and the first engagement hole 36 is provided, and two sets of the second locking piece 37 and the second engagement hole 38 are provided. The number of the holes 35 and 37 and the engagement holes 36 and 38 can be arbitrarily set according to the size of the stand 11 or the like.

  FIG. 2B schematically shows a cross section of the material 40 constituting the stand 11. That is, the raw material 40 is a cardboard made of a base material 41 and the resin film 42 is laminated on the front and back thereof, and thus has water resistance. The total thickness can be arbitrarily set (generally, it can be said that the thickness is generally about 0.5 to 1.0 mm). A water resistant layer may be coated instead of laminating the resin layer. In addition, when a resin film or a resin layer is provided on the surface, it can be processed so as to be filled in with a writing instrument such as a ballpoint pen or a pencil (for example, printing ink is applied).

(3). Assembly Procedure / Summary The stand 11 of the present embodiment is assembled generally by the procedure shown in FIG. That is, the unfolded state is laid on a table or the like so that the back plate 16 faces down, and the left and right side plates 17 and 18 are raised in a state where the lower auxiliary piece 33 is bent → the bottom plate 19 is raised → the ninth auxiliary piece 32 The bottom plate 19 is raised in a folded state → The first front plates 14 and 15 are raised and overlapped with the front auxiliary piece 31 to bend the upper plate 13 with respect to the back plate 16 and the first front plate 14 with respect to the upper plate 13. → The first locking piece 35 is fitted into the first engagement hole 36 → The second front plate 15 is bent and overlapped with the front auxiliary piece 31 and the second locking piece 37 is second engaged. The procedure of fitting into the hole 28 is taken.

  The front auxiliary piece 31 may be bent before or after the right side plate 18 is bent. Further, in the drawing, the lower auxiliary piece 29 is positioned inside the front auxiliary piece 31, but the lower auxiliary piece 29 may be overlapped on the outer side of the front auxiliary piece 31. Further, the first front plate 14 and the second front plate 15 can be reversed so that the first front plate 14 is positioned on the surface. The bag container 1 may be stacked on the back plate 16 from the beginning, or may be stacked on the back plate 16 before the first front plate 14 is bent. In any case, the neck 7 is forcibly fitted into the suspension support hole 12 of the upper plate 13 when the first front plate 14 is bent.

  In this embodiment, since the stand 11 is assembled into a hollow box as a whole, the adjacent plates reinforce each other, so that the sheet material mainly made of paper is manufactured as a raw material. As a whole, high rigidity can be secured. In particular, since the front portion has a two-plate structure of the first front plate 14 and the second front plate 15, higher rigidity is maintained.

  Further, in the present embodiment, the first front plate 14 is held so as not to be vertically or horizontally displaced with respect to the bottom plate 19 via the first locking piece 35, and in this state, the second front plate 15 is second locked. Since the front plates 14 and 15 are held together so as not to be displaced with respect to the right side plate 18 via the piece 37, both the front plates 14 and 15 have a high reinforcing function. As a whole, the stand 11 as a whole has a very high rigidity.

  Further, when the vertical auxiliary pieces 27 and 29 and the front auxiliary piece 31 are provided as in this embodiment, the vertical auxiliary pieces 27 and 29 serve as posture holding stoppers, so that the left and right side plates 17 and 18 The state of being folded back at 90 degrees with respect to the back plate 16 is maintained, which also contributes greatly to increasing the rigidity.

  Although the stand 11 of this embodiment can be manufactured using a cut sheet as a raw material, in terms of cost, it is preferable to perform punching and crease processing using Thomson using a raw sheet wound in a roll shape as a raw material. One mode of punching in that case is shown in FIG.

  That is, the stand 11 of the present embodiment has a first elongate plate 14 that protrudes greatly in an unfolded state and has an elongated shape as a whole. However, the stand 11 extends in the feed direction of the original fabric 53 and is adjacent to each other. 11, the feed posture is reversed and the first front plate 14 is arranged in the width direction of the original fabric. Thereby, it is possible to reduce the cost by reducing the margin part (the part to be discarded) as much as possible. Since the back plate 16, the left and right side plates 17, 18 and the second front plate 15 are connected in a state of spreading in series, processing with such a loss can be performed.

(4). Other Variations of First Embodiment Other functions can be added to or changed from the first embodiment. For example, as shown by the alternate long and short dash line in FIG. (B), a pressing portion 45 is formed on one or both of the front plates 14 and 15 and the back plate 16 to apply pressure to the bag 2 to push out the contents. Is possible. The pressing portion 45 is surrounded by a cut line (or slit) 46 except for its upper end, and the cut line 46 is divided by a breakable bridge 47 at one place or a plurality of places. Therefore, the bag 2 can be pushed by the pushing portion 45 by pushing the bridge 47 into pieces. The shape, size, and position of the pressing portion 45 can be set arbitrarily.

  The bag 2 is often printed with various displays, and the consumer may want to see the display on the bag 2. In this case, the stand 11 can be dealt with by manufacturing it with a transparent resin. If the stand 11 is manufactured with an opaque material, as shown in FIG. An observation window 48 of an appropriate size may be formed on either one or both of 15 and the back plate 16. It is also possible to close the viewing window 48 with a transparent film.

  Needless to say, the display similar to that of the bag 2 can be given to the stand 11. If the condition of strength can be cleared, a hole for pushing the bag 2 can be formed in the front plates 14 and 15 or the back plate 16 in advance. Further, by providing a cutout part in which the front plates 14 and 15 or the backboard 16 are partially surrounded by a sewing machine line, and the contents of the bag container 1 are reduced to a certain extent, It is also possible to provide a pressing hole. In this embodiment, the stand 11 has a trapezoidal shape that is symmetric when viewed from the side, but it can also be formed in a trapezoidal shape that is asymmetrical.

  As the holding means, a double-sided adhesive tape, a hook-and-loop fastener, a stapler, or the like can be used. In FIG. 3 (A), the example which provided the double-sided tape 49 in the front auxiliary | assistant piece 31 is shown with the dashed-dotted line. The exposed adhesive surface of the double-sided tape 49 is covered with a release paper (release paper).

(5). Other Modifications FIG. 5 (A) shows a second embodiment that is a separate row of suspension means for the bag container 1. This embodiment is the same as the first embodiment in that the suspension support hole 12 is formed in the upper plate 13, but in this embodiment, the cap is inserted into the first front plate 14 and communicated with the suspension support hole 12. A hole 50 is made. The cap insertion hole 50 is set to a size that allows the cap 4 and the flange 8 of the bag container 1 to pass through without resistance. In addition, a pair of protrusions 51 are formed at the opening of the suspension support hole 12 to prevent the suspension.

  FIG. 5B shows a third embodiment which is a separate row of the suspension means of the bag container 1. That is, in this embodiment, the folded portion 51 is formed on the inner peripheral edge portion of the suspension support hole 12 in the upper plate 13 to increase the strength. The folded portion 52 is welded or bonded to the upper plate 13. The folded portion 52 can be overlaid on the upper surface of the upper plate 13. A reinforcing plate separate from the upper plate 13 may be welded or bonded to the upper plate 13.

(6). Others The present invention can be embodied in various ways other than the above embodiments. For example, how the plates are connected can be freely selected. It is also possible to use a plurality of sheets such as two sheets for both the front plate and the back plate. Depending on the bag container, the spout may be biased to the right or left end of the bag, but the present invention can be applied to such a case.
