Abstract
Description
[Technical field]
[0001] The present invention relates to a refill container. [Background technology]
[0002] Conventionally, liquid agents such as shampoos and body soaps have been sold in dedicated containers and in many cases also in refill containers. As refill containers, bags such as standing pouches having a protruding pouring portion provided on the top or side for pouring the liquid agent into the dedicated container are widely known.
[0003] In order to transfer the liquid from such a refill container to a dedicated container, first, the tip of the pouring part is cut off to form a pouring outlet, and this pouring outlet is inserted into the opening of the dedicated container. After this, the liquid is transferred to the dedicated container using the pouring outlet, but since the refill container is made of a flexible film material, the pouring outlet is also soft and prone to being unstable. For this reason, the liquid is likely to spill during the transfer, causing problems such as dirtying the hands.
[0004] In this context, for example, Patent Document 1 discloses a bag in which a reinforcing tube is provided inside the portion that will become the pouring portion. Specifically, flexible films are overlapped and the periphery is heated and bonded to form a bag having a filling space surrounded by the bonded portion for filling with a liquid agent or the like.
[0005] A shape-retaining reinforcing tube is attached to the inside of the bag near the corner. The reinforcing tube is disposed so that one end faces the corner of the bag and the other end communicates with the filling space. When the corner of the bag is cut open, the reinforcing tube is exposed, and the liquid agent filled in the bag can be transferred to a dedicated container using the reinforcing tube.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 5-132069 Summary of the Invention [Problem to be solved by the invention]
[0007] However, the task of attaching the reinforcing tube to the inside of the bag is complicated and time-consuming.
[0008] The present invention has been made in consideration of the above problems, and a main object of the present invention is to easily form a shape-retaining pouring outlet in a refill container. [Means for solving the problem]
[0009] In order to achieve this objective, the pouring path shape retainer of the present invention is a pouring path shape retainer that is attached to the pouring portion of a refill container formed by laminating flexible films, and is characterized in that it comprises a reinforcing member that is placed on the outside of the pouring portion and an adhesive that fixes the reinforcing member to the extraction portion, and that the reinforcing member is provided with a fold line that extends in a direction along the pouring path of the contents formed on the inside of the pouring portion.
[0010] The pouring path shape retainer of the present invention is characterized in that the reinforcing member is made of a pair of plate materials laminated with the pouring portion sandwiched therebetween.
[0011] The pouring path shape retainer of the present invention is characterized in that the reinforcing member is formed by folding a plate material in two by bending processing, and is arranged so as to sandwich the pouring portion.
[0012] The pouring path shape retainer of the present invention is characterized in that the end portion of the reinforcing member located on the tip side of the pouring portion is inclined with respect to the pouring path.
[0013] The pouring path shape maintainer of the present invention is characterized in that the folding line is formed by a cut.
[0014] The refillable container of the present invention is a refillable container having a bag-shaped container body formed by laminating flexible films and a pouring portion continuous with the container body, and is characterized in that the pouring path shape retainer of the present invention is attached to the outside of the pouring portion.
[0015] The refill container of the present invention is characterized in that a cut line that intersects with the pouring path is provided in the pouring section, and a zipper portion that can freely open and close the pouring path is provided between the cut line and the pouring path shape retainer.
[0016] The refill container of the present invention is characterized in that a plurality of the cut lines are provided parallel to each other at intervals.
[0017] According to the pouring path shape retainer and refill container of the present invention, a reinforcing member is disposed on the outside of the pouring portion, and multiple fold lines are provided on the reinforcing member along the pouring path. As a result, when the tip of the pouring portion is cut off to form an injection port, and the reinforcing member is folded and unfolded along the fold lines, the flexible film of the pouring portion is also unfolded together with the reinforcing member. This allows the pouring path inside the pouring outlet and the pouring portion to have a desired inner diameter, and also allows the pouring portion to stand on its own while maintaining this inner diameter.
[0018] Therefore, when the contents of the refill container are transferred to the dedicated container, the pouring part reinforced by the reinforcing member can be stably inserted into the opening of the dedicated container, eliminating the problem of the contents spilling out of the pouring outlet. In addition, since the inner diameters of the pouring outlet and the pouring path are maintained at the desired cross section, it is possible to quickly refill the desired amount of contents by appropriately tilting the refill container.
[0019] In addition, by inclining the end of the reinforcing member located at the tip side of the pouring part with respect to the pouring path, the pouring outlet can be formed like the spout of a teapot, which makes it possible to prevent dripping from the pouring outlet when the contents are poured out.

[0022] <Refill container> As shown in the front view of FIG. 1 and the side view of FIG. 2, the refill container 100 comprises a container body 10 having a pouring portion 14 formed on the upper side thereof, and a pouring path shape retainer 20.
[0023] <Container body> The container body 10 is a so-called standing pouch, and is composed of two side wall flexible films 11a and 11b constituting the side walls, and a bottom wall flexible film 11c constituting the bottom wall. The two side wall flexible films 11a and 11b are laminated together with the bottom wall flexible film 11c folded in half sandwiched therebetween, and the four peripheral edges are heat-sealed so as not to be peeled off.
[0024] As a result, a storage section 13 capable of storing contents is formed in the container body 10. When the contents are filled into this storage section 13, the bottom wall flexible film 11c is pushed downwardly by the weight of the contents. As a result, the lower end of the container body 10 spreads and becomes self-supporting.
[0025] ≪Pour section≫ 1, in the pouring section 14 connected to the upper side of the container body 10, a space is formed by narrowing the storage section 13. This space functions as a pouring path 15 for pouring the contents from the storage section 13.
[0026] The pouring path 15 is opened by cutting the tip of the pouring part 14 along or using as a guide a cut line 16 formed in the middle of the pouring part 14, as shown in Fig. 3, to form a pouring outlet 151. This allows the contents filled in the storage part 13 to be poured out from the pouring outlet 151 via the pouring path 15 by tilting the refill container 100.
[0027] As shown in FIG. 1, a pouring path shape retainer 20 is attached to the pouring portion 14 having such a configuration.
[0028] <Pouring path shape retainer> As shown in FIG. 4( a ), the pouring path retainer 20 is attached so as to sandwich the pouring portion 14 from the outside, and includes a reinforcing member 21 and an adhesive material 22 .
[0029] As shown in Fig. 5(a) showing the front side and Fig. 5(b) showing the back side, reinforcing member 21 is made of a plate material with a folding line 212 in the center, and is folded so that the folding line 212 acts like a hinge, allowing it to be folded and unfolded. Reinforcing member 21 thus configured is formed in the shape of two joined right-angled trapezoids, with folding line 212 forming the lower base.
[0030] 5(a), a plurality of fold lines 211 are formed on the surface of the reinforcing member 21. The fold lines 211 may be formed by making a cut or may be formed by providing a fold. The extension direction of the fold lines 211 is formed parallel to the folding lines 212, and when attached to the outer surface of the pouring part 14 as shown in FIG. 1 and FIG. 3, the fold lines 211 are arranged in a direction along the pouring path 15.
[0031] 5(b), an adhesive 22 is applied to the back surface of the reinforcing member 21. Any material or type may be used for the adhesive 22 as long as it can be attached to the outer surfaces of the sidewall flexible films 11a and 11b. For example, a material that exhibits adhesive properties when heat is applied is preferable.
[0032] <Refill container manufacturing method> The procedure for attaching the above-mentioned pouring path shape retainer 20 to the pouring portion 14 of the container body 10 and manufacturing the refillable container 100 is as follows.
[0033] First, as shown in Fig. 5(b), the reinforcing member 21 is unfolded, in which the folding line 212 is configured like a hinge by folding processing. In this state, as shown in Fig. 6(a), the pouring part 14 is placed on one side of the folding line 212, which is the back side on which the adhesive material 22 is provided.
[0034] 6(b), reinforcing member 21 is folded along folding lines 212 to sandwich pouring portion 14 from the outside. In this state, reinforcing member 21 is fixed to pouring portion 14 by, for example, thermocompression bonding. In other words, side wall flexible films 11a and 11b are fixed to the back surface of reinforcing member 21 via adhesive 22.
[0035] At this time, the reinforcing member 21 is disposed below the cut line 16 formed in the middle part of the pouring portion 14. Also, the reinforcing member 21 is disposed so that the folding line 212 and the fold line 211 are in a direction along the pouring path 15 formed inside the pouring portion 14. Furthermore, the reinforcing member 21 is disposed so that the folding line 212 is located below the pouring portion 14.
[0036] In this way, as shown in Figure 1, when the refill container 100 is viewed from the front, the lower side of the pouring portion 14 is longer than the upper side, and the end of the reinforcing member 21 located on the tip side of the pouring portion 14 is inclined with respect to the pouring path 15.
[0037] According to the refill container 100 manufactured as described above, the tip of the spouting part 14 is cut off along the cut line 16 to form the spouting outlet 151, and then the reinforcing member 21 in the state shown in Fig. 4(a) is folded along the fold line 211 in a mountain fold, for example, by applying a compressive force with a finger in a direction perpendicular to the fold line 211, as shown in Fig. 4(b). In other words, the reinforcing member 21 is folded in a mountain fold with the front surface side as the mountain.
[0038] 4(b), the two side wall flexible films 11a, 11b constituting the pouring portion 14 and the reinforcing member 21 are deployed together. This allows the desired inner diameter to be formed in the pouring outlet 151 and the pouring path 15 inside the pouring portion 14. In addition, the pouring portion 14 can be made to stand on its own while maintaining this inner diameter.
[0039] Therefore, when the contents of the refill container 100 are transferred to a dedicated container, the pouring part 14 of the refill container 100 reinforced by the reinforcing member 21 can be stably inserted into the opening of the dedicated container, eliminating the inconvenience of the contents spilling and soiling the hands.
[0040] In addition, since the inner diameters of the spout 151 and the pouring path 15 can be maintained at the desired cross section, it is possible to quickly refill the desired amount of contents. Furthermore, by inclining the end of the reinforcing member 21 located on the spout 151 side with respect to the pouring path 15, the spout 151 can be formed like the spout of a teapot. This makes it possible to prevent dripping from the spout 151 when the contents are poured.
[0041] The pouring path corrector and refill container of the present invention are not limited to the above-described embodiments, and it goes without saying that various modifications are possible without departing from the spirit of the present invention.
[0042] For example, in the present embodiment, the reinforcing member 21 is formed so that the folding line 212 forms the lower base of a right-angled trapezoid, but it may be formed so that it forms the upper base. Also, the folding line 212 is formed like a hinge by bending, but this is not limiting. The reinforcing member 21 may be formed of a pair of plates formed into a right-angled trapezoid, or may be formed into a cylindrical shape.
[0043] Furthermore, the reinforcing member 21 is formed in a right-angled trapezoid when the refill container 100 is viewed from the front as shown in Fig. 1, but the shape may be any shape. For example, it may be formed in a square or rectangular shape.
[0044] Furthermore, the cut line 16 provided in the pouring portion 14 may be provided with a step between the side wall flexible film 11a side and the side wall flexible film 11b side, for example. In this way, when the tip of the pouring portion 14 is cut off using the cut line 16, a step is generated between the end faces of the side wall flexible film 11a side and the side wall flexible film 11b side, as shown in FIG.
[0045] As a result, when a chuck portion 17 capable of opening and closing the pouring path 15 is provided between the cut line 16 and the pouring path shape retainer 20 in the pouring portion 14, the step can be utilized to facilitate opening and closing of the chuck portion 17. Note that the chuck portion 17 does not necessarily have to be provided.
[0046] Furthermore, the reinforcing member 21 may be made of any material, such as cardboard or plastic, as long as it is capable of maintaining the inner diameter of the pouring outlet 151 and the pouring path 15 at a desired cross section.
[0047] The content contained in the refill container 100 may be any content, such as a liquid, powder, or granular material, as long as it can be poured out through the pouring path 15. [Explanation of symbols]
