[0006]

[Embodiment of the invention]

 The ring attachment device of this invention comprises a dummy container 1 and a ring 2 as shown in FIGS. 1 and 2, and the ring is attached to the ring attachment portion 4 of the fixed portion 3.

The dummy container 1 has a lower end opening and a hollow interior. The fixing part 3 provided at the lower part of the dummy container 1 will be described. As shown in FIGS. 6 to 8, a ring mounting part 4 having a diameter smaller than that of a cylindrical container body is provided at the bottom of the dummy container. It Holding protrusions 4a, 4b, 4c, which are substantially planar fan-shaped, are provided at three locations on the outer peripheral surface of the ring mounting portion 4 at equal intervals so as to protrude along the bottom surface 1a of the body of the dummy container (Fig. 8). A gap 5 is provided between each of the holding projections 4a-4c and the bottom surface 1a. Locking projections 6a, 6b, 6c are provided in the gaps 5 above the holding projections 4a to 4c in FIG. 6, and the locking projections are, in the illustrated example, the ends in the gap, that is, the ring 2. It is placed at the end of the direction of rotation (clockwise in Fig. 7) to fix the ring, which is the fixed direction of rotation. As shown in FIG. 9 to FIG. 12, the ring 2 has a substantially planar fan-shaped mounting notch 7a, which is provided at three positions at equal intervals on the inner peripheral edge thereof and has a width in the radial direction and a width in the circumferential direction. , 7b, 7c are cut away. Each of the mounting notches 7a to 7c is provided with an insertion portion 8a, 8b, 8c and a guide portion 9a from one end thereof to the other end (counterclockwise direction in FIG. 9) opposite to the fixed rotation direction of the ring 2. , 9b, 9c are formed side by side. Each of the guide portions 9a to 9c is formed in a protruding piece shape (or a rib shape) toward the inside of the ring 2 on the inner peripheral edge of each of the mounting notch portions 7a to 7c. Engagement recesses 10a, 10b, 10c are provided in each of the guide portions 9a-9c. The inner peripheral edge of the guide portion between the end portions of the respective insertion portions 8a to 8c and the engaging concave portions 10a, 10b, 10c adjacent thereto on the counterclockwise side in FIG. 9 gradually increases toward the engaging concave portions. The inclined surfaces 11a, 11b and 11c are provided, and the inclined surfaces have a function as a guide surface for guiding the locking projections 6a to 6c to the engaging recesses 10a to 10c. Here, the relationship between the ring 2 and the fixed portion 3 will be described with reference to FIGS. 1 to 5. The ring 2 can be rotatably fitted on the outer circumference of the ring attachment portions 7a to 7c of the fixed portion 3. Therefore, the holding projections 4a to 4c can be inserted into the insertion portions 8a to 8c of the mounting notches 7a to 7c, and the guide portions 9a to 9c are inserted into the gap 5 between the bottom surface 1a of the container body. It is possible to enter. By rotating the ring 2 in the fixed rotation direction (arrow direction) from the state of FIG. 13 in which the holding protrusions 4a to 4c are inserted into the insertion portions 8a to 8c of the notches 7a to 7c for mounting, the ring 2 is relatively rotated. The holding projection moves through the mounting notch, the guide portions 9a to 9c move inside the gap 5 below the holding projection in FIG. 5, and the engagement recesses 10a to 10c eventually move into the locking projections 6a to 6c. Thus, the ring 2 can be fixed to the dummy container 1 and the ring 2 can be prevented from coming off.

Next, the mounting operation of the ring 2 will be described. The ring mounting portion 4 of the dummy container 1 is placed on the upper side, and the ring 2 is opposed to the ring mounting portion 4 on the upper side thereof, and the ring is lowered to attach the holding projections 4a to 4c to the ring mounting notch as shown in FIG. Insert the insertion portions 8a to 8c of 7a to 7c. Then, when the ring 2 is rotated in the direction of the arrow in FIG. 13 from this state, the holding projections 4a to 4c relatively move in the mounting notches 7a to 7c from the insertion portions 8a to 8c to the guide portion. As a result, the guide portions 9a to 9c enter the gap 5 between the holding projections 4a to 4c and the bottom surface 1a, and the inclined surfaces 11a to 11c become the locking projections 6a to 6c as shown by the chain line in FIG. The contact projections gradually approach each other and contact each other, and further the respective locking projections slide on the inclined surface and engage with the engaging recesses 10a to 10c at the time when the engaging projections cross over the inclined surface (shown by the solid line in FIG. 4). As a result, the ring 2 is attached and fixed to the ring mounting portion 4 of the dummy container 1 as shown in FIG. Then, the attachment operation is completed at the stage of engagement. The ring 2 attached in the engaged state causes the holding projections 4a to 4c to be retained even if an external force (a force that vertically moves from above in FIG. 2) is applied to the ring 2 to separate it from the bottom bottom surface of the dummy container 1. Since the ring is supported by three points, it is possible to suppress the detachment of the ring, and the presence of the retaining projection is important for preventing detachment.

In order to remove the ring 2 from the dummy container 1, if the ring is rotated counterclockwise from the position shown in FIG. 1 with a stronger force than when it is attached, the locking projections 6a-6b and the engagement recesses 10a-1 are formed. The ring 2 may be lifted when the holding projections 4a to 4c correspond to the insertion portions 8a to 8c of the attachment cutouts 7a to 7c after the engagement with 0c is released.

In FIG. 1, the number of the holding projections and the corresponding mounting notches is three, and the ring is mounted by three-point support to stabilize the mounting. You may have more than one. In the case of two-point support, the holding protrusions are arranged to face each other, and the mounting notches are also arranged to face each other.

[0011]

[Effect of the invention]

 According to this invention, the ring is supported at two or three points by the engagement with the retaining projection of the dummy container, and the engagement projection and the engaging recess, so that the mounting is securely fixed. Since it is prevented from coming off, it can be installed in a stable state, there is no rattling during transportation, and the ring can be fixed simply by rotating the ring and engaging it with the dummy container. It does not require such strong force, and the mounting operation is simple. If the ring is supported at three points, the holding state will be further stabilized. By providing the guide part with an inclined surface for guiding the locking projection to the engagement recess, the ring can be smoothly rotated.
