Referring to FIG. 13, the push-up piece 8 pushes the lid-side projection 11a of the lid 11 rearward when the push piece 1 is pushed, thereby lifting the lid-side projection 11a of the lid 11 upward. At this time, the lid-side projection 11 a of the lid body 11 moves upward so as to get over the body-side projection 12 a of the container body 12 . As a result, the hook between the lid-side projection 11a of the lid body 11 and the body-side projection 12a of the container body 12 is released.

The bottom surface F6 of the bottom wall 6 is composed of a front bottom surface F61 that slidably contacts the container body 12 and a rear bottom surface F62 that is separated from the front bottom surface by a step 63 formed on the bottom surface F6. .

Referring to FIG. 6, in this embodiment, the front bottom surface F61 and the rear bottom surface F62 are each flat surfaces. In the present embodiment, as shown in FIG. 6, the front bottom surface F61 (step 63) is arranged to surround the front, right, and left sides of the rear bottom surface F62 in bottom view. Specifically, the front bottom surface F61 extends in the left-right direction along the front wall 2 of the bottom wall 6 to the left-right outer edge 6es1 (right wall 3) and the left-right outer edge 6es1 (left wall 4) of the bottom wall 6. , and extends rearward along the left-right direction outer edge 6es1 of the bottom wall 6. As shown in FIG. Furthermore, in the present embodiment, the right extending portion of the front bottom surface F61 and the left extending portion of the front bottom surface F61 are each connected to the guide projection 6b as shown in FIG.

Furthermore, the push piece 1 has two protrusions 7 on the rear bottom surface F62. The two protrusions 7 are arranged with a gap in the left-right direction. Each of the two projections 7 slidably contacts the container body 12 as shown in FIG. 13 .

Referring to FIG. 6, the push piece 1 has a bottom surface F6 of the bottom wall 6 formed with a step 63 so that the bottom surface F6 is divided into a front bottom surface F61 that contacts the container body 12 and a rear bottom surface F61 that does not contact the container body 12. It is divided into the side bottom face F62. In addition, the push piece 1 is provided with two protrusions 7 on the rear bottom surface F62 that does not contact the container body 12, and the two protrusions 7 are used as contact portions with the container body 12. In this case, as shown in FIG. 13, only the front bottom surface F61 of the bottom wall 6 and the top wall of the projection 7 come into contact with the container body 12 except for the guide protrusion 6b. That is, the push piece 1 can reduce the contact area with the container body 12 compared to the case where the entire bottom surface F6 of the bottom wall 6 is brought into contact with the container body 12 . As a result, the push piece 1 can reduce the frictional resistance caused by the contact between the push piece 1 and the container body 12 without coating the bottom surface F6 of the bottom wall 6 with silicon. Therefore, according to this embodiment, it is possible to provide the compact container 10 and the push piece 1 in which the frictional resistance generated when the push piece 1 is pushed in is reduced without applying silicone.

In this case, the front bottom surface F61 of the bottom wall 6 and the top wall of the projection 7 evenly contact the container body 12 . Therefore, in this case, the frictional resistance generated when pushing the push piece 1 can be further reduced.

Further, referring to FIG. 7, in the present embodiment, the convex portion 7 has an arcuate cross-sectional shape and extends in the front-rear direction. In this case, the convex portion 7 is in contact with the container body 12 in the front-rear direction in a state close to line contact, and is less likely to come into one-sided contact with the container body 12 . Therefore, in this case, the frictional resistance generated when pushing the push piece 1 can be further reduced.

Further, as shown in FIG. 6, in the present embodiment, the convex portion 7 is arranged on the rear bottom surface F62 so as to be in contact with the rear edge of the rear bottom surface F62 in bottom view, and It is arranged on the rear bottom surface F62 so as to be in contact with the lateral outer edge of the side bottom surface F62.

Table 1 below shows the results of analyzing the opening operation of the lid using the push piece, using the compact container as an analysis model.

Table 1 shows comparison data between the comparative model and practical models 1 to 4 when the comparative model is taken as 100%. In Table 1, practical models 1 to 4 are analytical models corresponding to the compact container 10 according to the first to fourth embodiments, respectively. The comparative model is an analytical model of a compact container using a conventional push piece 100 as a comparative example in FIG. Referring to FIG. 12, the configuration of push piece 100 is generally the same as push piece 1 of working model 1-4, except for bottom surface F6. The bottom surface F6 of the push piece 100 is composed of a plane F61 that contacts the container body 12 and a recessed plane F63 formed in the plane F61.

In Table 1, F1 is the rearward load (N: Newton) applied to the push piece 1 when the lid 11 is opened. In addition, in Table 1, F2 is the amount of force applied by the lid-side projection 11a to the body-side projection 12a when the engagement between the lid-side projection 11a of the lid body 11 and the body-side projection 12a of the container body 12 is released. It is an upward load (N: Newton). Furthermore, in Table 1, F2/F1 is the ratio (%: percent) of the load F2 to the load F1. To the right of the analytical numerical values obtained from these analysis results, the ratio (%) based on the analytical numerical values obtained from the comparative model is shown in parenthesis. For example, taking the relationship between the comparative model and the practical model 1 as an example, in the load F1, when the comparative model F1 = 8.3 (N) is 100%, the practical model 1 F1 = 6.037 ( N) is 72.7%, as shown in parentheses. Also, in the load F2, when F2 = 3.901 (N) of the comparison model is 100%, the ratio of F2 = 3.533 (N) of the implementation model 1 is 90.6%, as shown in parentheses. be. Furthermore, in the ratio of F2 / F1, when F2 / F1 = 47.00 (N) of the comparison model is 100%, the ratio of F2 / F1 = 58.52 (N) of the implementation model 1 is As shown, it is 124.5%.

Referring to Table 1, the practical models 1 to 4 can obtain a push-up load F2 substantially equivalent to that of the comparative model while keeping the load F1 applied to the push piece 1 small compared to the comparative model. I understand. In other words, in the practical models 1 to 4, the load F1 applied to the push piece 1 efficiently pushes up the lid-side projection 11a of the lid 11 as compared with the comparative model. This is thought to be due to the fact that the frictional resistance generated when pushing the push piece is reduced.

As for the tendency of the analysis results in Table 1, when the convex portion 7 is positioned on the rear side of the push piece 1 and positioned on the outer side of the push piece 1 in the left-right direction, a better effect is obtained, and the convex portion 7 is positioned on the front side of the push piece 1 and positioned on the center side of the push piece 1 in the left-right direction, the effect tends to diminish. According to the analysis results in Table 1, there are implementation model 4 (fourth embodiment), implementation model 3 (third embodiment), implementation model 2 (second embodiment), and implementation model 1 (first embodiment). Accordingly, its effectiveness is enhanced.

The foregoing describes exemplary embodiments of the invention and various changes can be made without departing from the scope of the claims. As described above, it is preferable to arrange the two protrusions 7 as in the first to fourth embodiments. can be placed. Also, when the compact container 10 is used as a compact container for cosmetics, between the container body 12 and the lid 11, cosmetics such as foundation, as well as makeup tools such as a puff, can be accommodated. Also, the external shape of the container body 12 is not limited to being circular in plan view. Furthermore, the various configurations adopted in each of the above-described embodiments can be replaced with each other or combined as appropriate.
