Description

[Technical Field]

[0001] The present invention relates to a holder, and more particularly to a holder that supports the upright position of a flexible packaging container containing liquid shampoo, conditioner, liquid kitchen detergent, or the like. [Background technology]

[0002] Traditionally, shampoos, conditioners, and the like have been distributed in fixed or rigid bottle containers made of synthetic resin or other materials. Recently, however, from the perspectives of environmental protection, effective use of resources, and economy, there has been an increase in the use of refillable flexible packaging containers (refillable containers) in which the contents are placed for distribution and sale. As such flexible packaging containers, there are bottle-type containers that have a bottom gusset at the bottom and can stand on their own. Although a freestanding flexible packaging container allows the contents to be used without having to be refilled into a synthetic resin container, as the contents are consumed, the shape of the bottom may become distorted and the container may no longer be able to maintain its freestanding position. Therefore, Patent Documents 1 and 2 propose holders for maintaining the upright position of flexible packaging containers. The holder described in Patent Document 1 hangs a packaging bag (flexible packaging container) from an outer carton to form a composite package, and maintains the composite package in an upright position by clamping the bottom of the outer carton to a base. In addition, the holder described in Patent Document 2 has a polygonal lower part and a cylindrical body with an upper part having an elliptical shell structure, and is configured to maintain the upright position of the soft packaging container by fitting the cylindrical body onto the lower half of the soft packaging container. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-158367 [Patent Document 2] Japanese Patent Application Laid-Open No. 2012-240720 Summary of the Invention [Problem to be solved by the invention]

[0004] While Patent Documents 1 and 2 both maintain the upright position of a flexible packaging container, Patent Document 1 requires an outer carton as an essential component and is not directly related to the flexible packaging container to maintain the upright position of the container. In other words, it is a holder that assumes the presence of an outer carton, which not only has the disadvantage of increasing the number of components but also makes it inconvenient because it requires the cumbersome task of hanging the flexible packaging container from the outer carton. Furthermore, Patent Document 2 has the disadvantage that the cylindrical body of the holder is simply fitted onto the bottom of the flexible packaging container, making it easy for the flexible packaging container to fall out of the holder. Patent Document 2 also suggests a configuration in which, when the sheet material from which the holder is made is folded to form a cylindrical body, an end of the sheet material is attached to a seal portion at one widthwise end of the flexible packaging container. However, this configuration results in the inconvenience of the flexible packaging container and the holder becoming integrated, making it difficult to easily separate them. Furthermore, the holder in Patent Document 2 is formed by folding a sheet material, and is therefore not designed to reliably maintain the shape of the cylindrical body, which has an elliptical shell structure, and therefore cannot be expected to maintain stability in a free-standing position.

[0005] The present invention has been devised to solve such inconveniences, and its object is to provide a holder that can be easily and quickly attached to the bottom of a flexible packaging container. Another object of the present invention is to provide a holder that has a structure that allows easy attachment and that will not accidentally fall off the flexible packaging container. A further object of the present invention is to provide a holder that can stably maintain the shape of the bottom of a flexible packaging container and maintain an upright position regardless of the amount of content remaining. [Means for solving the problem]

[0007] In order to achieve the above purpose, The present invention provides a holder that supports a freestanding posture of a flexible packaging container, which includes a body portion having a sealed portion at least on one end side in the width direction of sheet materials located on the front and back sides, and a bottom gusset provided on the lower side of the body portion, so that a downwardly facing recessed portion is formed between the bottom gusset and the sheet materials, The container has a bottom and a peripheral wall erected on the bottom, and is configured so that the lower part of the flexible packaging container can be accommodated in an accommodation space formed by the bottom and the peripheral wall, The bottom portion is provided with a protrusion that is positioned within the downward recess and stabilizes the upright position of the flexible packaging container.

[0008] Furthermore, the present invention provides a holder that supports a freestanding posture of a flexible packaging container, the holder comprising a body portion in which at least one widthwise end side of sheet materials located on the front and back sides is a sealed portion, a bottom gusset is provided on the lower side of the body portion, and a downwardly facing concave portion is formed between the bottom gusset and the sheet materials, The container has a bottom and a peripheral wall erected on the bottom, and is configured so that the lower part of the flexible packaging container can be accommodated in an accommodation space formed by the bottom and the peripheral wall, The peripheral wall may have a slit that extends the lower portion of the sealing portion outward from the peripheral wall, while the bottom may have a protrusion that is located within the downward recess and stabilizes the upright position of the soft packaging container. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a holder that can be easily and quickly attached to the lower part of a flexible packaging container and that can stably maintain the upright position of the flexible packaging container. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In this specification, unless otherwise specified, terms indicating positions or directions are based on the holder shown in Figure 4 as viewed from the direction of arrow a, with the direction of the arrow as viewed from the center of the holder being referred to as "rear" or "rear, rear" and the direction opposite the arrow being referred to as "front" or "front, forward," etc. These terms indicating positions, etc. are defined merely to facilitate understanding of the specification and will differ depending on the position from which the holder is viewed. Also, in the drawings, the cross section of the flexible packaging container is shown to have a thickness similar to that of the holder, but please understand that this is merely a stylized representation to avoid cluttering the drawings and that in reality it is much thinner than the thickness of each part of the holder.

[0012] In Fig. 1, holder 10 is a one-piece molded product injection-molded using a synthetic resin material, and is attached to the bottom side of flexible packaging container 11, which contains contents such as shampoo and conditioner. This flexible packaging container 11 is a bag container called a pouch bag, and has a body 13, a bottom gusset 14 (see Figs. 3 and 12), a top 15, and a mouth 16. As shown in Fig. 2, body 13 is formed from a pair of front and back sheets S1, and bottom gusset 14 is formed from a lower sheet material S2 that is folded into two pieces and sandwiched between the lower parts of sheet material S1. Top 15 is formed from top sheet material S3 (see Fig. 1) located between the upper parts of body 13, and mouth 16 is located within a central hole in sheet material S3. The mouth portion 16 is made of a resin molded body having a flange (not shown) at its lower end located on the inner surface of the top portion 15, and the mouth portion 16 is attached by adhering the flange to the inner surface of the top portion 15 (top sheet material S3).

[0013] The front and back sheet materials S1 are heat-sealed at the grid-like areas in Fig. 3 with the lower sheet material S2 sandwiched between their lower parts, thereby forming sealed portions 13A on both the left and right sides (both widthwise sides) of the body portion 13 and a bottom gusset 14 at the bottom. Here, as shown in Fig. 12, the bottom gusset 14 in this embodiment forms a curved bottom surface 14A whose center is lowest due to the weight of the contents when it is placed inside, and also forms a pair of downwardly facing recessed portions 14B on the left and right sides inside the sheet material, i.e., sealed portions 13A. In this embodiment, a pump unit 17 including a suction pipe (not shown) extending into the body 13 can be attached and detached to the mouth 16 of the flexible packaging container 11, and the contents can be discharged by holding the outer periphery of the mouth 16 between the fingers and pressing down on the head of the pump unit 17.

[0014] The holder 10 is a resin molded product made of a resin material such as polypropylene or polyethylene, or paper. As shown in FIGS. 4 to 11 , the holder 10 includes a bottom 19, a peripheral wall 20 erected on the bottom 19, and a protrusion 21 provided on the bottom for supporting the upright posture of the flexible packaging container 11. A storage space for the flexible packaging container 11 is formed inside the bottom 19 and the peripheral wall 20. As shown in FIG. 5 , the bottom 19 is formed in a generally cross-shaped planar shape with four openings 18 formed therein. These openings 18 allow hot water or the like to be discharged if it drips into the holder 10. Note that, as shown in FIG. 9 , the lower surface of the bottom 19 is positioned higher than the lower end of the peripheral wall 20, so that the discharge of hot water or the like is not impeded.

[0015] The peripheral wall 20 is composed of a first peripheral wall forming body 22 and a second peripheral wall forming body 23, which are shaped like strips and face each other so as to surround the outer periphery of the lower side of the body 13 of the flexible packaging container 11, and a pair of slits 25 extending in the vertical direction are formed between the ends of the first peripheral wall forming body 22 and the second peripheral wall forming body 23 at positions corresponding to each other by 180 degrees in the circumferential direction. More specifically, the first peripheral wall forming body 22 and the second peripheral wall forming body 23 are each composed of a central portion 22A, 23A positioned approximately parallel to each other, and a pair of wing portions 22B, 23B connected to both sides of the central portion and extending in a direction widening the gap between them. At this time, as shown in Figure 5, the end portion on the first peripheral wall forming body 22 side, i.e., the end portion of wing portion 22B, is shifted inward so that it is positioned more inward than the end portion of wing portion 23B of the second peripheral wall forming body 23 in a planar view.As a result, the ends of wing portions 22B, 23B have relative shapes or positions that are shifted inward and outward, forming a slit 25 between the ends, and the seal portion 13A protruding from the slit 25 is partially bent and protruding.

[0016] 7 and 8, the upper ends of the central portions 22A, 23A of the first peripheral wall forming body 22 and the second peripheral wall forming body 23 are positioned so that they lie in a substantially flat plane, and the upper ends of the wing portions 22B, 23B are formed in a mountain shape with higher peaks than the upper ends of the central portions 22A, 23A, and the peaks 22B1, 23B1 of the mountain shape are positioned slightly shifted toward the adjacent wing portion 22B, 23B, as shown in Figures 10 and 11. The inclined edges 22B2, 23B2 located between the peaks 22B1, 23B1 of the mountain shapes of the wing portions 22B, 23B are inclined so as to narrow downward, and these inclined edges 22B2, 23B2 form guides for inserting the sheet portion of the flexible packaging container, making it easier to guide the seal portion 13A into the slit 25. 5 and 6, the lower portions of the wing portions 22B, 23B of the first peripheral wall forming body 22 and the second peripheral wall forming body 23 are connected to each other by one face 19A of the cross that forms the bottom portion 19, and the central portions 22A, 22B are connected to each other by the other face 19B of the cross. Therefore, the rigidity of the entire holder 10 can be maintained, and no deformation occurs that would change the width of the slit 25 formed between the ends of the wing portions 22B, 23B.

[0017] As shown in Figures 5 and 12, the protrusions 21 on the bottom 19 are located immediately inside each slit 25 on an imaginary line connecting the pair of slits 25, and are positioned within the downwardly-facing recessed portion 14B of the bottom gusset 14. These protrusions 21 have an outer shape with a width and thickness that taper upward, i.e., a triangular shape with a thickness. Specifically, when the thickness of the protrusions 21 is defined as the direction along the line connecting the center C (see Figure 5) of the bottom 19 and the slit 25, as shown in Figures 9 and 12, the inclination angle of the inner surface 21B located on the opposite side to the slit 25 is large relative to the outer surface 21A located on the slit 25 side, so that the inner surface 21B fits along the bottom surface of the bottom gusset 14. Furthermore, the protrusion 21 has a hollow structure that is open on the bottom side (see FIGS. 6 and 9), which reduces the amount of molding material consumed for the holder 10 and makes it lighter.

[0018] In addition, the size of the holder 10 or the dimensions of each part in this embodiment is determined according to the size of the flexible packaging container 11 to be stored, and in this embodiment, the holder 10 has the dimensions of each part as exemplified below. Specifically, the maximum left-right width of the first peripheral wall forming member 22 is approximately 86.3 mm, the maximum left-right width of the second peripheral wall forming member 23 is approximately 92.9 mm, the distance between the centers of the first and second peripheral wall forming members 22, 23, i.e., the front-to-rear width or length of the holder 10, is 78.8 mm, and the width of the slit 25 is 2.4 mm. The height of the peaks of the mountain-shaped wings 22B, 23B is 38.9 mm, the height of the protrusion 21 is 18.1 mm, the distance between the uppermost ends of the protrusions 21 is 63.9 mm, and the distance between the lower ends of the inner surfaces 21B of the left and right protrusions 21 is 41.5 mm. The slit width is preferably 1 mm to 5 mm, and the distance between the ends of the first peripheral wall forming member 22 and the protrusions 21 can be determined within the range of 2 mm to 10 mm.

[0019] In the above configuration, when attaching holder 10 to the bottom of flexible packaging container 11, for example, holder 10 may be placed on a flat surface such as a table, and flexible packaging container 11 may be lowered from above into the storage space of holder 10 with its bottom facing downward. At this time, if seal portion 13A of flexible packaging container 11 is positioned between wings 22B and 23B, the upper inclined edge between wings 22B and 23B acts as a sheet portion insertion guide, allowing seal portion 13A to smoothly enter slit 25. When flexible packaging container 11 is placed in the storage space, the lower side of seal portion 13A is deformed into a wavy shape by the ends of wings 22B and 23B and protrudes outward from slit 25, and this wavy portion generates a strong frictional contact force between seal portion 13A and the end. Furthermore, when the flexible packaging container 11 has been completely accommodated in the holder 10, the protrusion 21 fits into the downward recess 14B of the bottom gusset 14, keeping the shape of the bottom gusset 14 constant.

[0020] Therefore, according to this embodiment, since the seal portion 13A of the flexible packaging container 11 protrudes from the slit 25 provided in the peripheral wall of the holder 10, the flexible packaging container 11 can be easily set in the holder 10 simply by dropping the lower part of the flexible packaging container 11 into the holder 10 from above. Moreover, due to frictional engagement between the ends of the first and second peripheral wall forming bodies 22, 23 that form the slit 25 and the seal portion 13A, the flexible packaging container 11 does not accidentally fall off, the unity of the flexible packaging container 11 and the holder 10 is maintained, and the upright position of the flexible packaging container 11 can be stably maintained regardless of the remaining amount of contents. Furthermore, in a configuration in which a protrusion 21 is provided that is located within a downwardly facing recessed portion 14B formed in the bottom gusset 14 of the flexible packaging container 11, the shape of the bottom gusset 14 can be kept constant, and the risk of the bottom of the flexible packaging container 11 losing its upright position can be avoided. Furthermore, a configuration in which the seal portion 13A at the widthwise end of the flexible packaging container 11 protrudes from the slit 25 and a configuration in which the protrusion 21 is positioned in the downward recessed portion 14B interact with each other, further increasing the reliability of maintaining the upright posture. Furthermore, by configuring the ends of the first peripheral wall forming body 22 and the second peripheral wall forming body 23 that constitute the peripheral wall to bend the protruding direction of the seal portion 13A, it is possible to obtain a unity between the flexible packaging container 11 and the holder 10. In this case, with the configuration in which the ends are shifted inward and outward, it is possible to make the means for preventing the seal portion 13A from slipping out extremely simple. Furthermore, since the central portions 22A, 23A of the first peripheral wall forming body 22 and the second peripheral wall forming body 23 are relatively lower in height than the wing portions 22B, 23B, the holder can be made smaller and waste of molding material can be avoided. Moreover, the configuration in which a sheet portion insertion guide is formed between the wing portions makes it easy to determine the relative positions of the flexible packaging container 11 and the holder 10, and the holder P10 can be smoothly attached to the bottom of the flexible packaging container 11. Furthermore, the protrusions 21 have a width and thickness that result in a tapered shape, and the angle of inclination of the inner surface is set larger than that of the outer surface that is located on the outer side, i.e., the side facing the slit 25, so that they are positioned to correspond to the shape of the bottom gusset 14, stabilizing the shape of the bottom gusset 14 and contributing to maintaining the freestanding posture. In this case, if the protrusions 21 have a hollow structure that opens on the bottom 19 side, this contributes to reducing the weight of the holder 10 and reducing waste of molding material. Furthermore, if the bottom 19 has an opening, it is easy to drain water, and even if it has a roughly cross-shaped planar shape, the rigidity of the holder can be maintained, and there is no problem such as the slit width changing.

[0021] Although the best configurations and methods for carrying out the present invention have been disclosed above, the present invention is not limited to these. That is, although the present invention has been particularly illustrated and described with respect to specific embodiments, those skilled in the art may make various modifications to the above-described embodiments in terms of shape, position or orientation, and other details of configuration, without departing from the scope of the technical idea and purpose of the present invention. Therefore, the above description has been given as an example to facilitate understanding of the present invention, and is not intended to limit the present invention. Therefore, even if some or all of the limitations on the shape and the like are changed to other shapes, the present invention will be substantially the same as the present invention and will be included in the spirit of the present invention.

[0022] For example, the flexible packaging container 11 in the above embodiment is shown as an example, and can be applied as long as it has a seal portion 13A and / or a bottom gusset 14. Specifically, although the illustration and description have been made of a case where front and back sheet materials S1 are used as members forming the body portion 13 of the flexible packaging container 11, it is also applicable to a case where a single sheet material is folded into two thicknesses, and the free ends are thermally bonded to each other to form a seal portion on one end in the width direction. In this case, the holder 10 in the present invention only needs to have a slit formed on one side. Furthermore, although the flexible packaging container 11 is shown equipped with a pump unit 17, it may also be one that does not have such a pump unit 17 and has a cap or the like (not shown) detachably attached to the opening 16.

[0023] Furthermore, although the peripheral wall 20 of the holder 10 is composed of two members, the first peripheral wall forming body 22 and the second peripheral wall forming body 23, this does not preclude modifications as necessary, such as, for example, discontinuing each peripheral wall forming body 22, 23 at the center to form four members.

[0024] Furthermore, the size, shape, and position of the protrusion 21 are not limited to the illustrated configuration example, and can be changed as long as they correspond to the size, shape, and position of the downward recessed portion 14B formed in the bottom gusset 14.

[0025] Furthermore, it is sufficient if there is at least one opening 18 provided in the bottom 19 of the holder 10. In this case, the bottom 19 may be made substantially circular or elliptical, with a hole of an appropriate size formed in the center, for example.

[0026] Furthermore, as shown in Figure 14(A), it is also possible to add a configuration in which a protrusion 30 whose tip is located inside the end of the first peripheral wall forming body 22 is provided on the inner side of the end of the second peripheral wall forming body 23, i.e., the inner side of the wing portion 23B, or a configuration in which a bent protrusion 31 is provided, as shown in Figure 14(B). In a configuration provided with such protrusions 30 and bent protrusions 31, when the flexible packaging container 11 is placed in the holder 10, the number of waves formed on the surface of the seal portion 13A increases, resulting in a stronger frictional engagement force being applied to the seal portion 13A, and the unity between the holder 10 and the flexible packaging container 11 can be maintained more firmly. 14(C), the end positions of the first peripheral wall forming body 22 and the second peripheral wall forming body 23 can be formed without being shifted inward or outward, and strip members 33 oriented in the left and right directions and parallel to each other can be connected to these end portions, so that the base side of the seal portion 13A projecting from the slit 25 is sandwiched not only by the ends of the first and second peripheral wall forming bodies 22, 23 but also by a wide width. In this configuration, the sandwiching width is preferably 2 mm to 10 mm to stabilize the upright position of the flexible packaging container. [Explanation of symbols]
