Hereinafter, preferred embodiments of a cylindrical container with a movable bottom according to the present invention will be disclosed with reference to the accompanying drawings. FIG. 1 is a conceptual diagram showing a configuration example of a cylindrical container 10 with a movable bottom according to the present invention and a cylindrical container stand 20 on which the cylindrical container with a movable bottom is placed, fixed, and used. The cylindrical container 10 with a movable bottom includes a bottom 12 that can move up and down as indicated by a double-headed broken arrow 11 along the inner wall of the container. The bottom 12 stops at the bottom of the cylindrical container 10 and does not descend below it. Further, a lid 13 having an appropriate shape and structure is attached according to the contents to be stored. The cylindrical container stand 20 has a stand base 21 at the lower part, and receives the lower end of the cylindrical container 10 at the upper part when the cylindrical container 10 with a movable bottom is pushed down as shown by the downward arrow 14. Are provided.

The coupling portion 22 receives the lower end of the cylindrical container 10 and needs to be provided with fixing means for preventing the main body of the container 10 from being lifted when the movable bottom 12 is pushed up at an appropriate position of the cylindrical container 10. There is. As this fixing means, for example, a well-known structure such as an engaging means or a screwing means between a notch portion and a collar portion formed in each of the lower end of the cylindrical container 10 and the coupling portion 22 can be applied. In addition, the stand base 21 needs to hold | maintain the cylindrical container 10 with a movable bottom part stably. Therefore, it is set as the structure which considered the mass of the cylindrical container 10 with a movable bottom part and the whole content which were provided in the upper part with a stable bottom face.

In the present invention, the upper end surface of the movable bottom 12 can be formed in a mortar shape having a low bottom. Even when the movable bottom 12 of the container is lifted while operating the external operation section 23 so as to be in close contact with the inner wall of the cylindrical container 10, even if the upper end surface of the movable bottom 12 of the container reaches the maximum upper limit, the movable bottom By forming the upper end surface of the mortar into a mortar shape with a low bottom, it becomes possible to easily take out all the contents without leaving a spoon, rice paddle, or the like.

In addition, when the contents to be stored in the cylindrical container according to the present invention are foodstuffs such as miso and jam in particular, after filling the foodstuffs in a bag made of an extremely thin plastic film, It can be stored in a cylindrical container. When foodstuffs such as miso and jam are objects to be stored, it is possible to store the objects to be stored more hygienically by filling and storing them in an ultra-thin plastic film bag or the like. . Furthermore, in this invention, the said cylindrical container 10 with a movable bottom part can be used for use as a packaging container of contents, such as miso and jam accommodated in the said container. The seller of the contents stored in the cylindrical container, for example, the miso seller, can sell the cylindrical container with a movable bottom to the consumer as a miso-filled cartridge filled with miso. The customer who has purchased the miso-containing cartridge will set the cartridge on the cylindrical container stand 20 and use it.

The cylindrical container stand 20 in FIG. 1 is provided with a push-up mechanism for pushing up the movable bottom 12 of the cylindrical container 10 with a movable bottom from below. Such a push-up mechanism includes, for example, an external operation unit 23, a push-up shaft 25 that is rotated by the external operation unit 23 to cause vertical movement, and a push-up member (push-up member fixed to the upper end of the push-up shaft 25. (Raising plate) 26. In this case, it is desirable that the push-up shaft 25 is configured not to rotate with the external operation unit 23 at least at the stage where rotation in the push-up direction starts.

The external operation unit 23 can be rotated in the direction of the arrow 24 or in the opposite direction. With such rotation, the push-up shaft 25 moves either up or down. The push-up plate 26 attached to the upper end of the push-up shaft 25 pushes up from the lower surface of the movable bottom 12 that moves up and down in close contact with the inner wall of the cylindrical container 10 with the movable bottom. If it is necessary to lower the movable bottom 12, the external operation unit 23 may be rotated in the opposite direction to the upward movement.

FIG. 2 shows an example of a structure in which the movable bottom 12 in the cylindrical container 10 with the movable bottom in the cylindrical container stand 20 is raised and lowered. The central hole of the external operation unit 23 is formed on the surface of the push-up shaft 25. A female thread is formed to engage with the formed (male) thread 25t. Therefore, the push-up shaft 25 can be raised as indicated by the arrow 11A by rotating the external operation unit 23 as indicated by the arrow 24A.

When the push-up shaft 25 is raised, the push-up plate 26 fixed to the upper end of the push-up shaft 25 is in close contact with the lower surface of the movable bottom 12 in the tubular container 10 (not shown). The lower surface of the bottom portion 12 in the container 10 is raised until it comes into contact with the stopper 25s at the lower end of the push-up shaft 25. Since the operation of raising the movable bottom 12 is performed as the upper surface of the stored contents is lowered, it is operated little by little every day or several times a week except for business use where the contents are frequently used. Often it is sufficient. The pitch of the thread 25t can also be selected according to the application.

The elevation width in such a structure is limited by the length of the push-up shaft 25. In this case, the length of the push-up shaft 25 is accommodated in the cylindrical container stand 25 shown in FIG. Therefore, in order to increase the length, it is necessary to increase the height of the container stand 25. However, an excessively large outer shape tends to be an obstacle at the installation location, which is not preferable in terms of balance of the cylindrical container 10 with a movable bottom.

As described above, the length of the push-up shaft 25 is limited by the height of the cylindrical container stand 20, but there is a limit to increasing the height of the cylindrical container stand 20. FIG. 3 shows a structural example in which the elevation width can be increased without excessively increasing the height of the cylindrical container stand 20. In this embodiment, a structure example is shown in which a push-up shaft has a so-called nested two-stage configuration with a cylindrical first push-up shaft 25a and a second push-up shaft 25b fitted inside. Is. In this embodiment, the push-up plate 26 is attached to the upper end of the second push-up shaft 25b. The second push-up shaft 25b is formed with a thread opposite to the surface of the first push-up shaft 25a.

Since such a configuration is employed, when the first push-up shaft 25a is rotated as indicated by an arcuate arrow 28A, the first push-up shaft 25a is raised to the upper limit as indicated by the upward arrow 11B, and the lower end When the external operation unit 23 is further rotated after the stopper 25s comes into contact with the lower surface of the operation unit, the first push-up shaft 25a rotates integrally with the external operation unit 23 in the clockwise direction. When the first push-up shaft 25a is further rotated clockwise as indicated by the arc-shaped arrow 28A, the second push-up shaft 25b and the inner surface of the first push-up shaft 25a are engaged with each other by a reverse screw. The second push-up shaft 25b rotates counterclockwise as indicated by an arcuate arrow 28B and rises as indicated by an arrow 11C. In this manner, the first push-up shaft 25a and the second push-up shaft 25b are interlocked to obtain a large lift width corresponding to the sum of the possible lift widths. Note that the push-up operation of the first push-up shaft 25a and the second push-up shaft 25b may be activated first. The rotation operation of the second push-up shaft 25b can be manually performed.

The cylindrical container with a movable bottom portion according to the present invention mainly stores amorphous contents that need to be taken into consideration when taking out, such as viscous substances such as miso, jam, marmalade, honey and the like as illustrated. The inconvenience sometimes felt can be resolved. The contents stored in a container with a large depth can always be removed near the opening above the container, and the user can insert a hand, spoon, etc. There is no need to insert a long special removal tool. Therefore, it is possible to easily take out the contents using a normal spoon, handle cup, etc., improving the work efficiency of cooking, etc., and the opportunity to carry foreign substances and bacilli inside. It can be greatly reduced.
