[Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-050400 A Summary of the Invention [Problem to be solved by the invention]

[0004] On the other hand, since the bottom surface (lower surface) of the push piece of the above-mentioned compact container is flat, silicone was applied to the bottom surface of the push piece by post-processing such as manual work in order to reduce the frictional resistance generated by contact between the push piece and the container body.

[0005] An object of the present invention is to provide a compact container and a push piece in which the frictional resistance generated when the push piece is pushed in is reduced without the need for a silicone coating. [Means for solving the problem]

[0006] The compact container of the present invention has a rear portion of a lid body connected to the rear portion of a container body by a hinge, and when the container body is covered with the lid body, the rearward protrusion of the lid body removably hooks onto the lower end of the forward protrusion of the container body, while a push piece housed in the container body pushes the rearward protrusion of the lid body rearward, thereby releasing the hooking between the forward protrusion and the rearward protrusion, and the bottom surface of the push piece is composed of a front bottom surface that slidably contacts the container body and a rear bottom surface separated from the front bottom surface by a step formed on the bottom surface, and further, the push piece has two protrusions on the rear bottom surface that are spaced apart in the left-right direction and that slidably contact the container body.

[0007] In the compact container of the present invention, the convex portion can be arranged on the rear bottom surface so as to contact the rear edge of the rear bottom surface when viewed from the bottom, and can also be arranged on the rear bottom surface so as to contact the outer edges of the rear bottom surface in the left and right directions.

[0008] In the compact container of the present invention, the convex portion can be arranged on the rear bottom surface so as to contact the rear edge of the rear bottom surface when viewed from the bottom, and can be arranged at a position between the left-right outer edges of the rear bottom surface and the left-right bisector of the rear bottom surface.

[0009] In the compact container of the present invention, the convex portion can be positioned on the rear bottom surface so as to contact the front edge of the rear bottom surface when viewed from the bottom, and can be positioned at a position closer to the left-right outer edge of the rear bottom surface than the left-right bisector of the rear bottom surface.

[0010] In the compact container of the present invention, the convex portion can be positioned on the rear bottom surface so as to contact the front edge of the rear bottom surface when viewed from the bottom, and can be positioned at a position closer to the left-right bisector of the rear bottom surface than the left-right outer edges of the rear bottom surface.

[0011] In the compact case according to the present invention, it is preferable that the height of the convex portion is equal to the height of the front bottom surface.

[0012] In the compact case according to the present invention, it is preferable that the protrusion has an arcuate cross-sectional shape and extends in the front-rear direction.

[0013] The push piece according to the present invention is the push piece described in any one of the above. Effect of the Invention

[0014] According to the present invention, it is possible to provide a compact container and a push piece in which the frictional resistance generated when the push piece is pushed in is reduced without the need for applying silicone. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Next, a compact case according to one embodiment of the present invention will be described with reference to the drawings. In the following description, "front" refers to the side where the push piece is arranged, and "rear" refers to the opposite side. In the following description, "right" and "left" refer to the front side of the compact case as the front. In addition, in the following description, "width" refers to the width in the left-right direction. In the following description, "upper" means the side of the lid body in addition to the usual meaning. In the following description, "lower" means the side of the container body in addition to the usual meaning.

[0017] In Fig. 1, reference numeral 1 denotes a compact case according to one embodiment of the present invention. A compact case 10 according to this embodiment is a round compact case as shown in Fig. 1.

[0018] Fig. 2 shows a cross section taken along line AA of compact case 10 in Fig. 1. Compact case 10 has a rear part of lid 11 connected to a rear part of case body 12 by hinge 13.

[0019] In this embodiment, the lid body 11 can be rotated around the hinge 13 in the up-down direction relative to the container body 12. In this embodiment, the lid body 11 is formed of a resin. An example of the resin is polypropylene. The lid body 11 has a recess C11 formed on the lower surface of the lid body 11. For example, a mirror can be attached to the recess C11. In addition, in this embodiment, the container body 12 is also formed of a resin. An example of the resin is polypropylene. The container body 12 has a recess C12 formed on the upper surface of the container body 12. For example, the contents can be accommodated in the recess C12. Specifically, an inner plate in which the contents are accommodated can be attached to the recess C12. The hinge 13 can be configured by, for example, a pin.

[0020] 2, when the container body 12 is covered with the lid 11, the rearward protrusion 11a of the lid 11 (hereinafter also referred to as the "lid-side protrusion 11a") is removably hooked onto the lower end of the forward protrusion 12a of the container body 12 (hereinafter also referred to as the "body-side protrusion 12a"), on the other hand, the push piece 1 housed in the container body 12 pushes the lid-side protrusion 11a of the lid 11 rearward, thereby releasing the hooking between the body-side protrusion 12a and the lid-side protrusion 11a.

[0021] 3 shows the push piece 1 from the front side. In this embodiment, a front wall 2 of the push piece 1 is a pushing portion for pushing the push piece 1 into the container body 12. In this embodiment, the outer surface of the front wall 2 is formed by a flat surface.

[0022] 4 shows the push piece 1 from the right side. In this embodiment, the outer surface of the right wall 3 of the push piece 1 is formed by a flat surface. In this embodiment, the left wall 4 of the push piece 1 is formed symmetrically with the right wall 3.

[0023] 5 shows the push piece 1 from above. In this embodiment, the upper wall 5 of the push piece 1 can be brought into slidable contact with the container body 12. In this embodiment, the outer surface of the upper wall 5 is configured by a flat surface. In this embodiment, the upper wall 5 is formed with a notch portion C5 in which the rear end of the upper wall 5 is notched.

[0024] FIG. 6 shows the push piece 1 from the bottom side. The bottom wall 6 of the push piece 1 can also be slidably brought into contact with the container body 12. In this embodiment, the bottom wall 6 of the push piece 1 has corners on both the left and right sides of the rear end of the bottom wall 6 cut out to form the corners as cutouts C6, and an extension 6c is formed between the cutouts C6. In this embodiment, the bottom wall 6 has two guide protrusions 6b. The two guide protrusions 6b are arranged on the bottom surface F6 of the bottom wall 6 so as to contact the cutout side rear end edge 6eb1 of the bottom wall 6, and are also arranged on the bottom surface F6 so as to contact the left and right outer end edges 6es1 (right wall 3, left wall 4) of the bottom surface F6. The two guide protrusions 6b slidably fit into guide grooves 12G formed in the container body 12, as shown in FIG. 13. This allows the push piece 1 to slide easily along the front-rear direction.

[0025] FIG. 7 shows the push piece 1 from the rear side. As shown in FIG. 7, the push piece 1 according to this embodiment has an internal space S that is open at the rear end of the push piece 1. The internal space S is partitioned by a right wall 3, a left wall 4, an upper wall 5, and a bottom wall 6, and the front side is closed by a front wall 2. A push-up piece 8 is disposed in the internal space S. FIG. 8 is a BB cross-sectional view of FIG. 5. The push-up piece 8 is a cantilevered support piece that protrudes rearward from the inner surface (rear surface) of the front wall 2. The upper side of the push-up piece 8 is opened by a notch C5 formed in the upper wall 5. Referring to FIG. 13, the push-up piece 8 pushes the lid-side protrusion 11a of the lid body 11 rearward by pushing the push piece 1, thereby pulling the lid-side protrusion 11a of the lid body 11 upward. At this time, the lid-side protrusion 11a of the lid body 11 moves upward so as to overcome the body-side protrusion 12a of the container body 12. As a result, 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.

[0026] The bottom surface F6 of the bottom wall 6 is composed of a front bottom surface F61 that is in slidable contact with 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.

[0027] 6, in this embodiment, the front bottom surface F61 and the rear bottom surface F62 are flat surfaces. In this embodiment, the front bottom surface F61 (step 63) is disposed so as to surround the front, right and left sides of the rear bottom surface F62 in a bottom view, as shown in FIG. 6. 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 toward the rear along the left-right outer edge 6es1 of the bottom wall 6. Furthermore, in this embodiment, the right-side extending portion of the front bottom surface F61 and the left-side extending portion of the front bottom surface F61 are each connected to the guide protrusion 6b, as shown in FIG. 6.

[0028] Furthermore, the push piece 1 has two protrusions 7 on the rear bottom surface F62. The two protrusions 7 are arranged at an interval in the left-right direction. As shown in FIG. 13, each of the two protrusions 7 is in slidable contact with the container body 12.

[0029] 6, the push piece 1 has a step 63 formed on the bottom surface F6 of the bottom wall 6, 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 F62 that does not contact the container body 12. In addition, the push piece 1 has two protrusions 7 on the rear bottom surface F62 that does not contact the container body 12, and the two protrusions 7 are the contact parts with the container body 12. In this case, as shown in FIG. 13, the parts of the bottom wall 6 that contact the container body 12 are only the front bottom surface F61 of the bottom wall 6 and the top wall of the protrusions 7, except for the guide protrusions 6b. That is, the push piece 1 can reduce the contact area with the container body 12 compared to when the entire bottom surface F6 of the bottom wall 6 contacts the container body 12. This allows the push piece 1 to reduce the frictional resistance caused by the contact between the push piece 1 and the container body 12 without applying silicone to the bottom surface F6 of the bottom wall 6. Therefore, according to this embodiment, it is possible to provide a compact container 10 and a push piece 1 in which the frictional resistance that occurs when the push piece 1 is pushed in is reduced without the need for applying silicone.

[0030] 7, in this embodiment, the height of the protrusion 7 is equal to the height of the front bottom surface F61. Specifically, the height of the protrusion 7 from the rear bottom surface F62 is equal to the height of the front bottom surface F61 from the rear bottom surface F62. In this case, the front bottom surface F61 of the bottom wall 6 and the top wall of the protrusion 7 are in even contact with the container body 12. Therefore, in this case, the frictional resistance generated when the push piece 1 is pushed in can be further reduced.

[0031] 7, in this embodiment, the protrusion 7 has an arcuate cross-sectional shape and extends in the front-rear direction. In this case, the protrusion 7 is in nearly line contact with the container body 12 along the front-rear direction, but is unlikely to come into one-sided contact with the container body 12. Therefore, in this case, the frictional resistance generated when the push piece 1 is pushed in can be further reduced.

[0032] 6, in this embodiment, the protrusion 7 is disposed on the rear bottom surface F62 so as to contact the rear end edge of the rear bottom surface F62 in a bottom view, and is disposed on the rear bottom surface F62 so as to contact the left-right outer edge of the rear bottom surface F62. Specifically, the protrusions 7 are disposed on the rear bottom surface F62 so as to contact the extension side rear end edge 6eb2. In addition, one of the two protrusions 7 is disposed on the rear bottom surface F62 so as to contact the defect side left-right outer edge 6es2 (the left-right outer edge of the rear bottom surface F62), and the other of the two protrusions 7 is also disposed on the rear bottom surface F62 so as to contact the defect side left-right outer edge 6es2.

[0033] Next, FIG. 9 is a bottom view of the push piece 1 according to the second embodiment of the present invention, as shown in FIG. 9. In this embodiment, the protrusion 7 is disposed on the rear bottom surface F62 so as to contact the rear end edge of the rear bottom surface F62 in the bottom view, and is disposed between the left-right outer edge of the rear bottom surface F62 and the left-right bisector LC of the rear bottom surface F62. Specifically, the protrusions 7 are disposed on the rear bottom surface F62 so as to contact the extension side rear end edge 6eb2, as in the first embodiment. In addition, one of the two protrusions 7 is disposed between the left-right outer edge 6es2 on the defect side and the left-right bisector LC, and the other of the two protrusions 7 is also disposed between the left-right outer edge 6es2 on the defect side and the left-right bisector LC. That is, the two protrusions 7 are arranged at positions excluding the positions of the left-right outer edges 6es2 of the missing portion and the left-right bisector LC in the positions where they contact the extension portion rear edge 6eb2.

[0034] Fig. 10 is a bottom view of the push piece 1 according to the third embodiment of the present invention, as seen from below. In this embodiment, the protrusions 7 are disposed on the rear bottom surface F62 so as to contact the front edge of the rear bottom surface F62 in a bottom view, and are disposed at a position closer to the outer left-right edge of the rear bottom surface F62 than the left-right bisector LC of the rear bottom surface F62. Specifically, the protrusions 7 are disposed on the rear bottom surface F62 so as to contact the front portions 63a of the steps 63. In addition, one of the two protrusions 7 is disposed closer to one of the two left-right outer parts 63s (left-right outer edges of the rear bottom surface F62) of the step 63 than the left-right bisector LC (for example, when one of the two protrusions 7 is on the right side, the right left-right outer part 63s), and the other of the two protrusions 7 is disposed closer to the other of the two left-right outer parts 63s of the step 63 than the left-right bisector LC (for example, when the other of the two protrusions 7 is on the left side, the left left-right outer part 63s). In this embodiment, the front part 63a of the step 63 is a curved part that protrudes toward the front side in a bottom view, as shown in FIG. 10. In this embodiment, the left-right outer part 63s of the step 63 is a part that extends in the front-rear direction.

[0035] Fig. 11 is a bottom view of the push piece 1 according to the fourth embodiment of the present invention, as seen from below. In this embodiment, the protrusions 7 are disposed on the rear bottom surface F62 so as to contact the front edge of the rear bottom surface F62 in a bottom view, and are disposed closer to the left-right bisector LC of the rear bottom surface F62 than the left-right outer edge of the rear bottom surface F62. Specifically, the protrusions 7 are disposed on the rear bottom surface F62 so as to contact the front portion 63a of the step 63, as in the third embodiment. In addition, one of the two protrusions 7 is positioned closer to the left-right bisector LC than one of the two left-right outer portions 63s of the step 63 (for example, when one of the two protrusions 7 is on the right side, the right-side left-right outer portion 63s), and the other of the two protrusions 7 is positioned closer to the left-right bisector LC than the other of the two left-right outer portions 63s of the step 63 (for example, when the other of the two protrusions 7 is on the left side, the left-side left-right outer portion 63s).

[0036] Table 1 below shows the results of an analysis of the opening action of a lid using a push piece, using a compact container as an analytical model.

[0037] [Table 1]

[0038] Table 1 shows comparative data between the comparative model and working models 1-4, with the comparative model being taken as 100%. In Table 1, working models 1-4 are analytical models corresponding to the compact case 10 according to the first to fourth embodiments, respectively. The comparative model is an analytical model of a compact case using a conventional push piece 100 as a comparative example, as shown in FIG. 12. Referring to FIG. 12, the configuration of the push piece 100 is generally the same as that of the push piece 1 of the working models 1-4, except for the bottom surface F6. The bottom surface F6 of the push piece 100 is composed of a plane F61 that contacts the case body 12, and a recessed surface F63 formed on the plane F61.

[0039] In Table 1, F1 is the load (N: Newton) applied to the push piece 1 in the backward direction when the lid body 11 is opened. In addition, in Table 1, F2 is the upward load (N: Newton) applied by the lid side protrusion 11a to the body side protrusion 12a of the container body 12 when the hook between the lid side protrusion 11a of the lid body 11 and the body side protrusion 12a of the container body 12 is released. In addition, in Table 1, F2 / F1 is the ratio (%: percentage) of the load F2 to the load F1. To the right of the analytical values ​​obtained from these analysis results, the ratio (%) based on the analytical values ​​obtained from the comparative model is shown in parentheses. For example, in the case of the relationship between the comparative model and the practical model 1, when the load F1 is F1=8.3 (N) of the comparative model is 100%, the ratio of the practical model 1 to F1=6.037 (N) is 72.7%, as shown in parentheses. In addition, for the load F2, when the comparative model's F2 = 3.901 (N) is taken as 100%, the ratio to the implemented model 1's F2 = 3.533 (N) is 90.6%, as shown in parentheses. Furthermore, in terms of the F2 / F1 ratio, when the comparative model's F2 / F1 = 47.00 (N) is taken as 100%, the ratio to the implemented model 1's F2 / F1 = 58.52 (N) is 124.5%, as shown in parentheses.

[0040] Referring to Table 1, it can be seen that, compared to the comparative model, the working models 1 to 4 are able to obtain a push-up load F2 that is almost the same as that of the comparative model while keeping the load F1 applied to the push piece 1 small. In other words, compared to the comparative model, the working models 1 to 4 are able to efficiently push up the lid-side protrusion 11a of the lid body 11 with the load F1 applied to the push piece 1. This is believed to be because the frictional resistance that occurs when the push piece is pushed in is reduced.

[0041] The analysis results in Table 1 tend to show that a better effect is obtained when the convex portion 7 is located on the rear side of the push piece 1 and on the outer side in the left-right direction of the push piece 1, and that the effect tends to be weaker when the convex portion 7 is located on the front side of the push piece 1 and on the central side in the left-right direction of the push piece 1. According to the analysis results in Table 1, the effect increases from Example Model 4 (fourth embodiment), to Example Model 3 (third embodiment), to Example Model 2 (second embodiment), to Example Model 1 (first embodiment).

[0042] The above is an explanation of an exemplary embodiment of the present invention, and various modifications can be made without departing from the scope of the claims. As described above, the two protrusions 7 are preferably arranged as in the first to fourth embodiments, but according to the present invention, the two protrusions 7 can be arranged at any position on the rear bottom surface F62. When the compact case 10 is used as a cosmetic compact case, cosmetics such as foundation and other cosmetic tools such as puffs can be stored between the case body 12 and the lid 11. The external shape of the case body 12 is not limited to a circular shape in a plan view. Furthermore, the various configurations adopted in each of the above-mentioned embodiments can be appropriately replaced with each other or combined. [Explanation of symbols]
