Description

  The present invention relates to a support frame for a packaging bag, and more particularly to a support frame used for a bag having a spout, and a packaging bag with a support frame.

  Conventionally, packaging bags having a spout at the upper end of the packaging bag have been implemented. It has an advantage that the contents such as liquid can be easily taken out. The packaging bag provided with such a spout has a gusset type structure in which folding portions are formed on both sides (refer to Patent Document 1) and a standing pouch type structure that can provide independence (Patent Document). 2) is known. Although the gusset type can obtain a certain degree of self-supporting property, since the bottom seal part is provided on the bottom surface, the bottom surface is difficult to flatten and the self-supporting property is somewhat unstable. The standing pouch type has the advantage that the self-supporting property can be reliably obtained, but since the packaging material forming the bottom portion is provided between the packaging materials forming the front portion and the back portion, the manufacture of the bag is not possible. It is not easy, it requires a dedicated device, and costs high. The bag itself can be manufactured easily and economically using a flat bag, but it does not have a bottom part and is not self-supporting, which is disadvantageous for display and display of products. For example, there is an inconvenience that cannot be placed with the cap removed.

FIG. 1 is a perspective view of a packaging bag support frame 1 according to a first embodiment, and FIG.
The packaging bag support frame 1 includes a front part 2 and a back part 3 that face each other, a top part 5 that connects the top parts 2 a and 3 a of the front part 2 and the back part 3, and lower end parts of the front part 2 and the back part 3. The bottom part 7 which connects 2b and 3b in the position which left | separated is provided. The top portion 5 is provided with a through-hole 6 through which the portion of the spout 11 of a packaging bag 10 (described later) having a spout 11 at the upper end is inserted. Although the side surface of the packaging bag support frame 1 is open, a side surface portion can be provided as appropriate.

  The support frame 1 for packaging bags is made of a sheet-like material. The illustrated example is configured to be assembled by folding a sheet or other sheet-like material as illustrated in a development view in FIG. Thereby, manufacture is performed simply. As the sheet material, paper, synthetic resin material, or the like is used. The thickness of the packaging bag is not limited as long as it is rigid enough to provide independence when used over a packaging bag. Paper is inexpensive, easy to print, easy to recycle, and resource-saving.

The shape of the front part 2 and the back part 3 which oppose is not specifically limited. Although the thing which has the outline which the periphery of the packaging bag mounted internally is one preferable aspect, in addition to the rectangle shown in FIGS. 1 and 2, for example, an appropriate shape as shown in FIGS. You can get none. Moreover, it is also free to provide a through hole as appropriate. The front part 2 and the back part 3 can be subjected to arbitrary printing such as product names and patterns.
The side surface shape of the support frame 1 is a mountain shape in which the front part 2 and the back part 3 extend downward from the top part 5 downward. As a whole, it has an isosceles triangle shape with the bottom 7 as the base. For this reason, it comes to be able to become stable and independent. The front portion 2 and the back portion 3 are usually formed as flat surfaces, but may be formed in, for example, a curved shape that bulges outward. In that case, the side shape is an isosceles triangle as shown in FIG. The isosceles part of the shape is not a straight line but a bulging curve.

  The top part 5 which connects each upper end part 2a, 3a of the front part 2 and the back part 3 is formed according to the size of the packaging bag and spout used. Usually, the top portion 5 is formed in a thin strip shape or a linear shape. Usually, since the spout has a predetermined diameter (thickness), it is preferable to form it in a thin strip shape (for example, about 5 to 10 mm in width) because the spout fits well. But the top part 5 may be formed in the linear shape with almost no width so that it may become a bending part which forms the boundary line (folding curve) of the front part 2 and the back part 3, and the planar shape is not limited.

The top portion 5 is provided with a through hole 6 through which the portion of the spout 11 of the packaging bag 10 having the spout 11 at the upper end is inserted. The packaging bag 10 including the spout 11 is covered with the support frame 1 (inside the support frame 1), and the spout 11 is inserted through the through hole 6 and protrudes to the outside of the support frame 1. The through hole 6 is formed according to the size and shape of the spout 11.
FIG. 5 illustrates the packaging bag 10 with the support frame 1, wherein (a) is a front view and (b) is a side view. That is, the packaging bag 10 is installed in a space surrounded by the front part 2, the back part 3, the top part 5 and the bottom part 7 of the support frame 1, and the spout 11 is inserted through the through-hole 6 to the outside of the support frame 1. Shows the set state protruding. By covering the packaging bag 10 so as to be wound in the vertical direction by the support frame 1, the packaging bag 10 can be mounted on the support frame 1. A cap 13 is attached to the spout 11 of the packaging bag 10. The packaging bag 10 is preferably a flat bag having four or three sides sealed, but is not particularly limited.
The inner height of the support frame 1 is preferably formed smaller than the height of the packaging bag 10 excluding the spout 11, and the lower part of the packaging bag 10 filled with the contents is bent by the weight of the contents, so that the support frame 1 Stability increases when it is placed on the bottom 7 of 1 in a planar shape. Examples of the contents include liquids, viscous materials, and powders.

Moreover, it is good to comprise so that the flange part 12 formed in the spout 11 of the packaging bag 10 may be latched by the through-hole 6. FIG. In this case, a diameter portion that is slightly smaller than the outer diameter of the flange portion 12 may be formed in the through hole 6. The flange portion 12 is formed in many known spouts that are used when the spout 11 is attached to the packaging bag 10 by mechanical means. The flange portion 12 is a portion that protrudes from the outer surface of the cylindrical portion that becomes the content passage of the spout 10, and may be a single case or a plurality of cases.
FIG. 6 is a plan view of the support frame 1 showing a configuration example of the through-hole 6. As shown in the figure, if a plurality of cuts 6a are appropriately provided at the edge of the through hole 6, it is easy to insert and lock the flange portion 12 of the spout 11.

  The depth of the bottom 7 (width: the length between the lower ends 2b, 3b of the front portion 2 and the back portion 3) connecting the lower ends 2b, 3b of the front portion 2 and the back portion 3 at a distance is the top portion. It is formed larger than the width of 5. It is preferable that the bottom 7 has a plate shape on the entire surface, which is strong and easy to stabilize. For example, it is easy to superimpose the bottom portions 7a and 7b connected to the front portion 2 and the back portion 3 and to bond the bottom portions 7a and 7b (see FIGS. 1 and 2). However, the shape and structure of the bottom portion are not limited. For example, as shown in the bottom view of the support frame 1 in FIG. 7, the lower end portions 2 b and 3 b of the front portion 2 and the rear portion 3 are arranged at appropriate positions. The bottom portions 7c and 7d to be connected may be formed. In short, the bottom portions 2b and 3b of the front surface portion 2 and the back surface portion 3 may be connected so as to be held at spaced positions.

In addition, when assembling by bending one sheet-like material, the position of the bonded portion to be superimposed is not limited. In addition to the bottom portion as described above, it is possible to overlap and adhere not only to the bottom portion but also to an appropriate position such as the top portion. Further, if the overall shape retaining property can be obtained, the overlapping portion is not necessarily provided. Adhesion can be appropriately used, such as a double-sided adhesive tape or a single-sided adhesive tape. A stapler or the like may be used regardless of adhesion. Alternatively, it is also possible to connect both ends of one sheet-like material by using an insertion method (for example, a convex piece and a notch portion into which the convex piece is inserted and locked).
FIG. 8 shows an example in which both ends of one sheet-like material are connected portions. In this example, notches 8a and 8b are provided in bottoms 7a and 7b connected to the front part 2 and the back part 3 respectively, and the notches 8a and 8b of the bottoms 7a and 7b are shown in FIG. As shown in the bottom view of FIG.

  Moreover, as shown in FIG. 9, the front part 2 and the back part 3 may be provided with perforations 2c, 3c in the lateral direction so that they can be separated vertically. Then, when using, depending on the type of contents, there may be a case where the contents are easier to push out when the front and back portions of the bag are exposed, and the support frame 1 is cut at the perforations 2c and 3c. It is easy to push the bag, and the upper portions 2d and 3d of the front portion 2 and the rear portion 3 remain, so that the product name and the like are easy to understand. In this case, the back surface of the upper part 2d of the front part 2 or the upper part 3d of the back part 3 may be bonded in advance to the bag with a double-sided adhesive tape or the like.

  As mentioned above, although the form for implementing this invention was demonstrated, this invention is not limited to what was mentioned above, In the range of the summary of this invention, it can implement by changing suitably, adding, etc. is there.
