Description

Technical Field

[0001] The present invention relates to a refill container.

Background Art

[0002] Conventionally, liquid agents such as shampoo and body soap are often sold filled in a dedicated container and also sold filled in a refill container. As a refill container, a bag body such as a standing pouch provided with a pouring-out part for injecting the liquid agent into the dedicated container protruding from its upper part or side part is generally widely known.

[0003] In order to transfer the liquid agent from such a refill container to a dedicated container, first, the tip of the pouring-out part is cut off to form a pouring-out port, and this pouring-out port is inserted into the opening of the dedicated container. After that, the liquid agent is transferred to the dedicated container using the pouring-out port. However, since the refill container is made of a flexible film material, the pouring-out port is also likely to be soft and unstable. Therefore, the liquid agent is likely to spill during the transfer, causing problems such as soiling the hands.

[0004] Under such circumstances, for example, Patent Document 1 discloses a bag provided with a reinforcing tube inside the part that becomes the pouring-out part. Specifically, flexible films are overlapped and the peripheries are heated and joined to form a bag provided with a filling space for filling a liquid agent or the like inside, surrounded by the joined part.

[0005] Then, a reinforcing tube having shape retention is attached inside the vicinity of the corner of this bag. The reinforcing tube is arranged such that one end faces the corner of the bag and the other end communicates with the filling space. As a result, when the corner of the bag is cut off and opened, the reinforcing tube is exposed, so that the liquid agent filled in the bag can be transferred to the dedicated container using this reinforcing tube.

[0015] The refillable container of the present invention is characterized in that the dispensing section is provided with a cut line that intersects with the dispensing path, and a chuck portion that can open and close the dispensing path is provided between the cut line and the dispensing path shape retainer.

[0016] The refillable container of the present invention is characterized in that multiple cut lines are provided parallel to each other with intervals in between.

[0017] According to the dispensing path shape-retaining device and refillable container of the present invention, a reinforcing member is placed on the outside of the dispensing section, and a plurality of fold lines are provided on this reinforcing member along the dispensing path. As a result, after cutting off the tip of the dispensing section to form an inlet, when the reinforcing member is folded and unfolded along the fold lines, the flexible film of the dispensing section also unfolds together with the reinforcing member. This makes it possible to form a desired inner diameter in the dispensing outlet and the dispensing path inside the dispensing section, and also makes it possible to make the dispensing section self-supporting while maintaining this inner diameter.

[0018] Therefore, when transferring the contents of the refillable container to the dedicated container, the reinforcing spout can be stably inserted into the opening of the dedicated container, eliminating problems such as the contents spilling from the spout. In addition, since the inner diameter of the spout and spout path is maintained at the desired cross-sectional shape, the desired amount of contents can be quickly transferred by tilting the refillable container appropriately.

[0019] Furthermore, by inclining the end of the reinforcing member located at the tip of the dispensing section with respect to the dispensing path, the spout can be formed to resemble a teapot spout. Therefore, it is possible to prevent dripping from the spout when dispensing the contents. [Effects of the Invention]

[0020] According to the present invention, it becomes possible to easily form a spout having shape retention property in a refill container.

Embodiments for Carrying Out the Invention

[0022] ≪Refill Container≫ As shown in the front view of FIG. 1 and the side view of FIG. 2, the refill container 100 includes a container body 10 having a pouring part 14 formed in the upper part on the side, 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 side walls, and a bottom wall flexible film 11c constituting a bottom wall. These are laminated with two side wall flexible films 11a and 11b so as to sandwich the bottom wall flexible film 11c folded in two, and the peripheral edges on all four sides are heat-sealed so as not to be peeled off.

[0024] As a result, a storage section 13 capable of holding contents is formed in the container body 10. When contents are filled into this storage section 13, the weight of the contents causes the flexible film 11c for the bottom wall to be pushed outwards. This causes the lower end of the container body 10 to spread out and become self-supporting.

[0025] ≪Pour section≫ On the other hand, as shown in Figure 1, a space is formed in the dispensing section 14, which is continuous with the upper side of the container body 10, by narrowing the storage section 13. This space functions as a dispensing path 15 for dispensing the contents from the storage section 13.

[0026] The dispensing path 15 is opened by cutting off the tip of the dispensing section 14 along or using the cut line 16 formed in the middle of the dispensing section 14 as a guide, as shown in Figure 3, thereby forming the dispensing outlet 151. As a result, by tilting the refill container 100, the contents filled in the storage section 13 can be dispensed through the dispensing path 15 and out of the dispensing outlet 151.

[0027] As shown in Figure 1, a dispensing path shaping device 20 is attached to the dispensing section 14 with this configuration.

[0028] <<Dispensing Path Shape Retainer>> As shown in Figure 4(a), the dispensing path retainer 20 is attached by clamping the dispensing section 14 from the outside, and includes a reinforcing member 21 and an adhesive 22.

[0029] As shown in the front view of Figure 5(a) and the back view of Figure 5(b), the reinforcing member 21 is made of a plate material with a folding line 212 in the center. It is folded to form a hinge-like structure at the folding line 212, allowing it to be folded and unfolded. The reinforcing member 21 with this configuration is formed in the shape of two connected right-angled trapezoids with the folding line 212 as the base.

[0030] Furthermore, as shown in Figure 5(a), multiple fold lines 211 are formed on the surface of the reinforcing member 21. The fold lines 211 may be formed by making cuts or by creating creases. The direction in which the fold lines 211 extend is formed parallel to the folding lines 212, and when attached to the outer surface of the dispensing section 14 as shown in Figures 1 and 3, they are arranged in a direction along the dispensing path 15.

[0031] Furthermore, as shown in Figure 5(b), adhesive 22 is applied to the back surface of the reinforcing member 21. The adhesive 22 can be of any material or type, as long as it can adhere to the outer surface of the flexible side wall films 11a and 11b. For example, a material that exhibits adhesive properties when heat is applied is preferred.

[0032] ≪Manufacturing method for refillable containers≫ The procedure for attaching the above-mentioned dispensing path shaping device 20 to the dispensing section 14 of the container body 10 and manufacturing the refillable container 100 is as follows.

[0033] First, as shown in Figure 5(b), the reinforcing member 21, which has been folded to form a hinge-like structure at the folding line 212, is unfolded. In this state, as shown in Figure 6(a), the dispensing section 14 is placed on the back side where the adhesive 22 is applied, on one side of the folding line 212.

[0034] Next, as shown in Figure 6(b), the reinforcing member 21 is folded using the folding line 212, and the dispensing section 14 is sandwiched from the outside. In this state, the reinforcing member 21 is fixed to the dispensing section 14 by, for example, heat sealing. In other words, the flexible side wall films 11a and 11b are fixed to the back surface of the reinforcing member 21 via the adhesive 22.

[0035] In this configuration, the reinforcing member 21 is positioned below the cut line 16 formed in the middle of the dispensing section 14. Furthermore, the folding line 212 and the fold line 211 of the reinforcing member 21 are positioned in a direction that aligns with the dispensing path 15 formed inside the dispensing section 14. In addition, the reinforcing member 21 is positioned such that the folding line 212 is located below the dispensing section 14.

[0036] As a result, as shown in Figure 1, when the refillable container 100 is viewed from the front, the lower side of the dispensing section 14 is longer than the upper side, and the end of the reinforcing member 21 located on the tip side of the dispensing section 14 is inclined with respect to the dispensing path 15.

[0037] As described above, with the refillable container 100 manufactured, the tip of the dispensing part 14 is cut off using the cut line 16 to form the dispensing spout 151. Then, with the reinforcing member 21 in the state shown in Figure 4(a), a compressive force is applied to the fold line 211 in a direction perpendicular to the fold line 211, for example with a finger, as shown in Figure 4(b), causing the fold line 211 to be folded into a mountain fold. In other words, the surface side of the reinforcing member 21 is made into a mountain fold.

[0038] As shown in Figure 4(b), the two flexible side wall films 11a and 11b that make up the dispensing section 14 and the reinforcing member 21 both unfold. This allows the desired inner diameter to be formed in the dispensing outlet 151 and the dispensing path 15 inside the dispensing section 14. Furthermore, the dispensing section 14 can be made to stand on its own while maintaining this inner diameter.

[0039] Therefore, when transferring the contents of the refillable container 100 into the dedicated container, the dispensing part 14 of the refillable container 100, which is reinforced by the reinforcing member 21, can be stably inserted into the opening of the dedicated container, thus eliminating problems such as the contents spilling and soiling one's hands.

[0040] Furthermore, since the inner diameters of the spout 151 and the dispensing path 15 can be maintained at the desired cross-sectional shape, it is possible to quickly refill the desired amount of contents. In addition, by inclining the end of the reinforcing member 21 located on the spout 151 side with respect to the dispensing path 15, the spout 151 can be formed to resemble a teapot spout. Therefore, it is also possible to prevent dripping from the spout 151 when dispensing the contents.

[0041] The dispensing path corrector and refillable container of the present invention are not limited to the embodiments described above, and it goes without saying that various modifications are possible without departing from the spirit of the present invention.

[0042] For example, in this embodiment, the reinforcing member 21 is formed such that the folding line 212 forms the lower base of a right-angled trapezoid, but it may also be formed so that it forms the upper base. Also, although the folding line 212 is formed like a hinge by bending, it is not limited to this. The reinforcing member 21 may be made of a pair of plates formed into a right-angled trapezoid, or it may be formed in a cylindrical shape.

[0043] Furthermore, although the reinforcing member 21 is formed as a right-angled trapezoid when the refill container 100 is viewed from the front, as shown in Figure 1, its shape can be anything. For example, it may be formed as a square or a rectangle.

[0044] Furthermore, the cut line 16 provided in the dispensing section 14 may be designed to have a step between the flexible sidewall film 11a side and the flexible sidewall film 11b side. In this case, when the tip of the dispensing section 14 is cut using the cut line 16, a step is created on the end faces of the flexible sidewall film 11a side and the flexible sidewall film 11b side, as shown in Figure 7.

[0045] As a result, when a chuck portion 17 capable of opening and closing the dispensing path 15 is provided between the cut line 16 and the dispensing path shape retainer 20 in the dispensing portion 14, the step can be used to easily open and close the chuck portion 17. Note that the chuck portion 17 is not necessarily required.

[0046] Furthermore, the reinforcing member 21 can be made of any material that can maintain the inner diameter of the spout 151 and the dispensing path 15 in the desired cross-section, such as cardboard or plastic.

[0047] Furthermore, the contents to be contained in the refill container 100 can be any form of material that can be dispensed through the dispensing route 15, such as liquid, powder, or granules. [Explanation of Symbols]
