Description

  The present invention relates to a container that further stores a cosmetic container that stores cosmetics such as perfume, and more particularly to a positioning and feeding container that aligns the ridge lines of the container when the container is rotated to open and close the cosmetic container.

Conventionally, as shown in FIG. 9, this type of positioning and feeding container includes a cup cylinder 103 for storing a cosmetic container (not shown), a drive sleeve 105 for slidingly fitting the cup cylinder 103, and the drive sleeve 105. The sliding projection 131 of the cup cylinder 103 that stores the cosmetic container includes a spiral tube 107 that slides, a lower cover 109 that fits the spiral tube 107, and an upper cover 111 that fits the drive sleeve 105. Is slidably fitted into the spiral groove 171 of the spiral tube 107 through the slit 151 of the drive sleeve 105. Then, the cosmetic container housed therein is opened and closed by the relative rotational movement of the lower cover 109 and the upper cover 111, and the ridgeline between the lower cover 109 and the upper cover 111 at the bottom dead center and the top dead center at the time of opening and closing. Are the same.
In addition, although the prior art document was investigated regarding this invention, an effective patent document was not able to be discovered.

  In the conventional case, the rotation angle of the lower cover 109 and the upper cover 111 is determined by the groove shape of the slit 151 into which the sliding protrusion 131 is fitted and the lead angle α of the spiral groove 171 as shown in FIG. The

  Therefore, in order to accurately match the ridgelines M1 to M4 of the lower cover 109 and the ridgelines N1 to N4 of the upper cover 111 as shown in FIG. 9A, the stroke end of the sliding protrusion 131 is shown in FIG. As indicated by the solid line, it is necessary to accurately position in terms of machining accuracy as well as design.

  However, this is difficult in practice, and it is common knowledge to take some clearance 151a (indicated by a single-point mirror line in FIG. 9C).

  However, when there is such a clearance 151a, when a strong torque is applied in the direction of the arrow (shown in FIGS. 9B and 9C) during the rotating operation, the slope 171a of the spiral groove 171 intersecting with the slit 151 The sliding protrusion 131 is lifted and overruns, and rotates excessively until reaching the end of the clearance 151a, and as shown in FIG. N4 is inconsistent with N4, and there is a disadvantage that the appearance of the container is not clean.

  Further, as a result of forcibly rotating extra force by a strong torque, a force is directly applied to the edge portion of the end of the clearance 151a, which causes bending and deformation.

  In particular, the drive sleeve 105 in which the slit 151 is formed has a thin wall thickness due to the nature of this type of container, and is easily bent and deformed when a strong force is applied, so that the amount of overrun tends to be large. . In addition, the amount of overrun tends to be large even when deformed due to wear over time.

  Therefore, in the past, it was difficult to accurately match the ridge line of the lower cover 109 and the ridge line of the upper cover 111.

  As another inconvenience, when the sliding protrusion 131 overruns, the head portion (not shown) of the cosmetic container (not shown) stored in the cup cylinder 103 is too depressed and depressed at the bottom dead center. At the time of top dead center, it was surfaced, and in any case it was very unfriendly.

  Further, various printing may be performed on the surface of the container. In such a case, it is required to stop at a predetermined position, but it has been difficult for the above reason in the past.

  The object of the present invention is to eliminate the above-mentioned drawbacks and to accurately match the ridge lines of the container when the container is rotated to open and close the cosmetic container.

  Another object is to facilitate the design and processing of the container.

  It is another object of the present invention that there is no possibility of displacement when printing is performed on the container surface.

In order to achieve the above object, a positioning and feeding container according to the present invention is a container made of a rotationally symmetric body for storing a cosmetic container, and the container is slidably fitted with a cup cylinder for storing the cosmetic container and the cup cylinder.
