  In the present embodiment, the inner cap 4 can be removed from the container body by grasping the outer cap while the outer cap 5 is coupled to the inner cap 4. Thereby, the removal operation | work of the inner cap 4 becomes easy compared with the case where a container main body is removed by holding an inner cap. The outer cap 5 is screwed to the inner cap 4, and the inner cap 4 is fitted to the container body 2. Therefore, the removal of the inner cap is achieved by pulling the outer cap upward without requiring rotation. This makes it easier to remove the inner cap 4 than when the inner cap is rotated and removed.

  Thus, the container 2 according to the present embodiment is very easy to remove the inner cap 4 without using a particularly complicated configuration. Thereby, according to the storage container 2, what is called a universal design which is easy to handle for anyone (for example, children and elderly people) is achieved.

  In the present embodiment, the container has been described by taking a bottle-shaped container body as an example. However, the storage container may be a tube-shaped or bag-shaped container. The inner cap is attached to the container main body via an annular member. However, the inner cap may be attached to the container body without using the annular member. For example, the inner cap may be provided with a sealing structure that is provided with a coupling means on the container body and is in close contact with the container body.

  In the present embodiment, the outer cap and the inner cap are coupled by screwing. However, the outer cap and the inner cap may be coupled by different means. In the present embodiment, the outer cap is formed in the same outer shape as the shoulder portion of the receiving container in plan view. However, the outer cap may have other shapes as long as it can cover and seal the inner cap.

  Next, the spouted container S for refilling the container V with contents will be described. FIG. 10 shows a spouted container S according to an embodiment of the present invention, FIG. 10 (A) is a front view of the spout part 6 of the spouted container S, and FIG. 10 (B) is a spout part of the spouted container S. FIG. 10C is a plan view of the spout part 6 of the spouted container S, and FIG. 10D is a perspective view of the spout part 6 of the spouted container S.

  The spouted container S includes a spout part 6 and a main body container part (not shown) following the spout part 6. The spout-equipped container S inserts the spout portion 6 into the opening 24 of the storage container 2 and refills the storage container 2 with the liquid as the contents. The main body container portion has an accommodation space like a bottle container or a bag container, and accommodates contents for refilling.

  The spout part 6 includes a base 60 connected to the main body container part and a cylindrical member 61 extending upward from the base 60. However, the cylindrical member 61 may be directly connected to the main body container without using the base 60. The cylindrical member 61 penetrates in the extending direction and communicates with the accommodation space of the main body container portion.

  The cylindrical member 61 includes a spiral portion 62 at a substantially center in the extending direction on the outer periphery. As is well known in the art, the spiral portion 62 is screwed into a female screw portion provided on a lid cap (not shown) that seals the spout portion 6 of the spouted container S. Thereby, the spouted container S is sealed by the lid cap.

  The cylindrical member 61 includes a pair of recesses 63 that extend in the extending direction and open in the radial direction. The pair of recesses 63 are provided at positions shifted by 180 ° in the circumferential direction in plan view. Furthermore, the cylindrical member 61 includes a flange portion 64 on the base 60 side in the extending direction. The flange portion 64 is provided so as to have a disk shape in plan view.

  Next, a state in which the spouted container S is attached to the container body 2 for refilling will be described. FIG. 11 is an enlarged cross-sectional view showing the vicinity of the neck in a state where the cylindrical member 61 of the spouted container S is fitted into the opening 24 of the container body 2.

  The spouted container S is fitted into the receiving container 2 in a state in which the annular member 3 is fitted. The outer peripheral end of the spiral portion 62 has a shape corresponding to the hole portion 31 of the annular member 3, and is in close contact with the inner peripheral wall portion 32 of the annular member 3 with the tubular member 61 fitted in the hole portion 31. . The inner peripheral end of the folded portion 35 of the annular member 3 corresponds to the outer peripheral surface of the cylindrical member 61, and is in close contact with the cylindrical member 61 in a state where the cylindrical member 6 is fitted in the hole 31. The folding part 35 and the spiral part 62 are engaged in the vertical direction. Thus, the spout unit 6 is fixed to the storage container 2. After being fixed, even if the operator does not support the spouted container S by hand, it is stably held.

  The spiral portion 62 of the cylindrical member 61 is in close contact with the inner peripheral wall portion 32 of the annular member 3 in the circumferential direction, and the outer peripheral surface of the cylindrical member 61 is in close contact with the folded portion 35 of the annular member 3 in the circumferential direction. doing. However, the recess 63 extending in the extending direction beyond the spiral portion 62 on the outer peripheral surface of the cylindrical member 61 is not in contact with the annular member 3. Thereby, the recessed part 63 is connected with the exterior of each container, and functions as an air hole. In other words, the spouted container S is fixed to the storage container V in a state where the spouted container S is fitted in the storage container V, but the contents of the spouted container S are recessed when the storage container V is filled. Since 63 functions as an air hole, it is filled smoothly.

  Next, the refilling step will be described. FIG. 12 shows a flowchart of a refilling method for transferring the contents of the spouted container S to the storage container V.

  First, a storage container V (see FIG. 9D) composed of a container body 2 to which an outer cap 5, an inner cap 4 and an annular member 3 are attached, and a spouted container S are prepared (S-1). . At this time, the storage container V consumes the contents, the storage space 23 is almost empty, and the spouted container sufficiently stores the contents.

  Next, in a state where the outer cap 5 and the inner cap 4 are coupled, the outer cap 5 and the inner cap 4, that is, the cap is removed (S-2). At this time, the cap is pulled upward and removed. Thereby, the storage container V becomes the container main body 2 in which the annular member 3 is fitted in the opening 24 (see FIG. 9B).

  Next, the spout-equipped container S is fitted into the storage container V in which the annular member 3 is fitted in the opening 24 (S-3). Thereby, the cylindrical member 61 of the spouted container S is fitted into the hole 31 of the annular member 3. At this time, the spiral portion 62 of the cylindrical member 61 is in close contact with the inner peripheral surface (inner wall) of the inner wall portion 31 of the annular member 3, and the outer peripheral surface of the cylindrical member 61 is in close contact with the folded portion 35 of the annular member 3. Thereby, the container S with a spout is fixed to the storage container V.

  Next, the contents (liquid) of the spouted container S are filled into the storage container V (S-4). Thereby, the container V is refilled. At this time, the contents are moved by gravity by positioning the spouted container S upward and the container V downward. However, if the main body container portion of the spouted container S is a bag or the like, the contents may be transferred by pressing the main body container portion. When the contents move to the receiving container 2 through the cylindrical member 61, the recess 63 functions as an air hole.

  The embodiment disclosed this time is an example, and the present invention is not limited to this. The present invention is defined by the terms of the claims, rather than the scope described above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The container according to the present invention can be used for refilling the liquid as the contents.
