Therefore, the outer cap 5 and the inner cap 4 function as a cap that seals the opening 24 of the container body 2.

  When the outer cap 5 rotates and is screwed into the inner cap 4, the locking protrusion 56 provided on the inner frame portion 52 of the outer cap 5 engages with the locking portion 46 of the inner cap 4. That is, the locking projection 56 rides over the small locking portion 46a, comes into contact with the large locking portion 46b, and fits into the gap between the small locking portion 46a and the large locking portion 46b. As a result, the inner cap 4 is circumferentially locked.

  Since the inner cap 4 is positioned with respect to the container body 2, the outer cap 5 is also positioned with respect to the container body 2. In the present embodiment, the outer cap 5 is positioned with respect to the container body 2 at a position where the ellipse of the container body 2 and the ellipse of the outer cap 5 have the same major axis (see FIG. 9D).

  As shown in FIG. 9, the container V is assembled in the following procedure. First, the container body 2 is prepared (see FIG. 9A). Then, the annular member 3 is fitted into the container body 2 (see FIG. 9B). Next, the inner cap 4 is attached so as to cover the opening 24 of the container body 2 (see FIG. 9C). At this time, the annular member 3 is interposed between the opening 24 and the inner cap 4 and seals the container body 2 and the inner cap 4. Next, the male screw portion 45 of the inner cap 4 is screwed into the female screw portion 55 of the outer cap 5 to couple the outer cap 5 to the inner cap 4 (FIG. 9D). At this time, the spout 41 of the inner cap 4 is sealed by the sealing portion 58 of the outer cap 5.

  In the present embodiment, the outer cap 5 can be removed from the container body by grasping the outer cap while the outer cap 5 is coupled to the inner cap 4. This facilitates the work of removing the inner cap 4 as compared with the case of grasping the inner cap and removing the container body. 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 accomplished by pulling the outer cap upward without the need for rotation. This facilitates the removal of the inner cap 4 as compared with the case where the inner cap is rotated and removed.

  As described above, in the container 2 according to the present embodiment, the inner cap 4 can be removed very easily without having a particularly complicated structure. As a result, the container 2 achieves a so-called universal design that is easy for anyone (eg, children or the elderly) to handle.

  In the present embodiment, the container has been described by taking the bottle-shaped container body as an example. However, the storage container may be a tube-shaped or bag-shaped container. Further, the inner cap is attached to the container body via the 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 coupling means on the container body, and may be provided with a sealing structure in close contact with the container body.

  Further, in the present embodiment, the outer cap and the inner cap are screwed together. However, the outer cap and the inner cap may be joined by different means. In the present embodiment, the outer cap is formed to have the same outer shape as the shoulder portion of the storage 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 container S with a spout for refilling the container V with contents will be described. FIG. 10 shows a container S with a spout according to an embodiment of the present invention, FIG. 10 (A) is a front view of the spout portion 6 of the container S with a spout, and FIG. 10 (B) is a spout portion of the container S with a spout. 6 is a side view of FIG. 6, FIG. 10 (C) is a plan view of the spout portion 6 of the spout-equipped container S, and FIG. 10 (D) is a perspective view of the spout portion 6 of the spout-equipped container S.

  The spout-equipped container S includes a spout portion 6 and a main body container portion (not shown) following the spout portion 6. In the container S with spout, the spout portion 6 is inserted into the opening 24 of the container 2 to refill the container 2 with the liquid as the content. The main body container portion has a storage space such as a bottle container and a bag container, and stores the contents for refilling.

  The spout portion 6 includes a base 60 connected to the main body container portion 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 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 is provided with a spiral portion 62 on the outer periphery at substantially the center in the extending direction. As is well known in the art, the spiral portion 62 is screwed onto a female screw portion provided on a lid cap (not shown) that seals the spout portion 6 of the spout-equipped container S. As a result, the container S with spout is sealed by the lid cap.

  Further, the cylindrical member 61 includes a pair of recesses 63 extending in the extending direction and opening in the radial direction. The pair of recesses 63 are provided at positions displaced by 180 ° in the circumferential direction in plan view. Further, 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 a plan view.

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

  The spout-equipped container S is fitted into the container 2 with the annular member 3 fitted thereto. The outer peripheral end of the spiral portion 62 has a shape corresponding to the hole portion 31 of the annular member 3, and the tubular member 61 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 tubular member 61, and the tubular member 6 is in close contact with the tubular member 61 in the state of being fitted into the hole 31. The folding portion 35 and the spiral portion 62 engage with each other in the vertical direction. By these, the spout part 6 is fixed to the container 2. After being fixed, the spout-equipped container S can be stably held even if the worker does not support it by hand.

  The spiral portion 62 of the tubular 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 tubular member 61 is in close contact with the folded portion 35 of the annular member 3 in the circumferential direction. is doing. However, the concave portion 63 extending in the extending direction beyond the spiral portion 62 on the outer peripheral surface of the tubular member 61 is not in contact with the annular member 3. As a result, the recess 63 communicates with the outside of each container and functions as an air hole. That is, the spout-equipped container S is fixed to the accommodating container V in a state where the spout-equipped container S is fitted into the accommodating container V. Since 63 functions as an air hole, it is filled smoothly.

  Next, the step of refilling will be described. FIG. 12 shows a flow chart of a refilling method for transferring the contents of the spout-equipped container S to the storage container V.

  First, a container V (see FIG. 9D) including the container body 2 to which the outer cap 5, the inner cap 4, and the annular member 3 are attached, and the spout-equipped container S are prepared (S-1). . At this time, the storage container V has consumed the contents, the storage space 23 is substantially empty, and the spout-equipped container sufficiently stores the contents.

  Next, with the outer cap 5 and the inner cap 4 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. As a result, the 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 container S with spout is fitted into the container V in which the annular member 3 is fitted in the opening 24 (S-3). As a result, the tubular member 61 of the spout-equipped container S is fitted into the hole 31 of the annular member 3. At this time, the spiral portion 62 of the tubular member 61 comes into 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 tubular member 61 comes into close contact with the folded portion 35 of the annular member 3. As a result, the container with spout S is fixed to the container V.

  Next, the container (V) is filled with the content (liquid) of the spout-equipped container S (S-4). As a result, the container V is refilled. At this time, the contents are transferred by gravity by arranging the container with spout S at the upper side and the container V at the lower side. However, if the main body container part of the spout-equipped container S is a bag body or the like, the contents may be transferred by pressing the main body container part. When the contents move to the container 2 through the tubular 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 shown not by the scope described above but by the claims, and is intended to include all modifications within the meaning and range equivalent to the claims.

  The storage container according to the present invention can be used for refilling a liquid as a content.
