Description

[Detailed description of the invention] <Industrial application field> This invention relates to compact containers, and in particular to compact containers in which an inner tray filled with cosmetics etc. is rotatably and detachably attached to the container body. Regarding improvements.

《Prior art》 A container body, an inner plate disposed on the upper part of the container body, and a lid body disposed on the upper part of the container body are rotatably connected to each other by a hinge on the rear end side so that they can be opened and closed. 2. Description of the Related Art Compact containers with a double structure that are filled with cosmetics and other cosmetics and store cosmetic tools such as puffs between the container body and an inner tray are conventionally known. In this type of double-structured compact container, there is one in which the inner tray itself is configured to be detachable from the container body side in order to facilitate refilling with cosmetics and the like.

A compact container with this kind of structure was developed in 1988.
This is shown in Publication No. 163104. This conventional compact container has an inner plate removably attached to a hinge piece that is hinged to the container main body side by a fitting structure. As for the fitting structure between the inner plate and the hinge piece, there are two types in which the two are slidably attached and detached using a dovetail groove structure parallel to the hinge axis, and a fitting structure in which the fitting protrusion of the inner plate is inserted into the fitting hole of the hinge piece elastically. A press-fitting configuration is adopted.

《Problems to be solved by the invention》 In the case where the inner plate and the hinge piece are connected in a sliding manner using a dovetail groove structure, there is no looseness in the fitting of the two, and moreover, both can be smoothly slid to be attached and detached. To make this possible, the machining of dovetails and dovetail grooves requires extremely high precision. As a result, defective products are likely to occur, resulting in poor yields and expensive products. This dovetail structure is not suitable for compact containers made of molded plastic.

Further, in a structure in which the inner plate and the hinge block are detachably attached by elastic press-fitting between the concave and convex portions, it is difficult to optimize the strength of the fitting between the two, resulting in the following problems.

Increasing the strength of the fit between the inner plate and the hinge piece is preferable because the inner plate does not play during normal use, but it requires a very large force to remove the inner plate, making it difficult to replace the inner plate. It gets very bad. In particular, when the inner plate is pulled too hard, it suddenly comes off at a certain point, and the impact causes the cosmetics remaining on the inner plate to scatter. Furthermore, if strong force is applied to attach or detach the inner plate, the hinge may be damaged by the force.

On the other hand, if the strength of the fit between the inner plate and the hinge piece is reduced, the inner plate can be easily attached and removed, but the inner plate may wobble during normal use, making it easier to accidentally come off.

This invention was devised in view of the above-mentioned conventional problems.The purpose of this invention is to be able to reliably connect the inner plate and the hinge piece with relatively high fitting strength, and to be able to easily attach and remove the inner plate. To provide a compact container which can be easily used without applying excessive force to other parts.

<Means for solving the problem> Therefore, in this invention, the fitting part provided at the rear end of the inner plate is made to correspond to the upper part of the fitting part of the hinge piece, and the inner plate is pressed downward. The two fitting portions are configured to be elastically press-fitted, and
When the operating part of the lever rotatably attached to the hinge piece is pressed, the operating part of the lever presses the rear end of the inner plate upward to separate the two fitting parts.

《Operation》 Since the mounting direction of the inner plate is vertical, even if a relatively large force is required to fit the inner plate to the hinge piece, the inner plate can be pressed from the top to the bottom using the container body as a pedestal, and the hinge piece can be attached to the hinge piece. By fitting, the inner plate can be connected to the hinge piece with a very simple operation without applying excessive force to weak parts such as the hinge.

When removing the inner plate from the hinge piece, there is no need to press the hinge piece and forcefully pull the inner plate upward; instead, it is sufficient to press the operating portion of the lever provided on the hinge piece. This allows the inner plate to be pushed upward by the action part of the lever without applying unreasonable force to weak parts such as the hinge, and the inner plate can be smoothly removed without causing a shock that would cause it to suddenly come off. The inner plate will come off the hinge piece.

<<Example>> Figs. 1 to 5 show a compact container according to an embodiment of this invention.

10 is a container main body, 12 is an inner plate whose outer diameter is smaller than the container main body 10, 14 is a hinge piece for hinge-coupling the inner plate 12 to the container main body 10 side, 1
Reference numeral 6 denotes a lid that covers the upper part of the container body 10 while enclosing the inner plate and the hinge piece 14.

The container body 10, the hinge piece 14 to which the inner plate 12 is attached, and the lid body 16 are hinged together at the rear end side by a common hinge shaft 18, and can rotate around this hinge shaft 18 and freely open and close. It's summery. Cosmetic material 20 is filled in the recess on the upper surface of the inner tray 12, and a puff 22 is stored in the space between the inner tray 12 and the recess on the upper surface of the container body 10.

A locking recess 24 is provided at the front end portion of the container body 10, and a locking convex portion 26 is provided at the lower front end of the lid 16 corresponding thereto. When the upper part of the container body 10 is closed with the lid 16, the minute protrusions provided in the locking protrusion 26 and the locking recess 24 engage with each other, and the lid 16 is locked in the closed state.

As shown in Figures 2, 3, and 4, the inner plate 1
A positioning recess 28 is formed at the center of the corner between the bottom surface and the rear surface at the rear end portion of 2. Fitting pins 30 are formed protruding from both inner side walls of the positioning recess 28, respectively.

On the other hand, the hinge piece 14 alternately has bearing parts 32, 32 through which the hinge shaft 18 passes, and the front side thereof has the positioning recess 2 of the inner plate 12.
The positioning portion 34 is sized to fit within the 8. Fitting holes 36 corresponding to the fitting pins 30 of the inner plate 12 are formed at both ends of the upper surface of the positioning portion 34 . This fitting hole 36 is open upward, has a narrowed part in the middle, and has a circular shape corresponding to the fitting pin 30 at the lowermost part.

A lever 38 for removing the inner plate 12 is attached to a portion of the upper surface of the hinge piece 14 located between the fitting holes 36, 36. The lever 38 is an integrally molded part in which a rear plate-shaped operating part 38a and a front plate-shaped operating part 38b are continuous with a step, and a pin hole 38c is formed at the rear corner of the lower surface. . Corresponding to this pin hole 38c, a lever pin 40 is formed on the opposite surface side of the portion of the hinge piece 14 where the fitting holes 36, 36 are formed, and by fitting the pin hole 38c to this lever pin 40, the lever 38 is rotatably attached to the center portion of the upper surface of the hinge piece 14. When the action part 38b of the lever 38 is in close contact with the positioning part 34 of the hinge piece 14, this action part 38b forms a part of the positioning part 34, and the inner plate 1
It will fit tightly into the positioning recess 28 of No. 2.

FIG. 3 shows a state in which the inner plate 12 is properly fitted to the hinge piece 14. To achieve such a fitted state, the fitting pin 30 of the inner plate 12 is positioned above the fitting hole 36 of the hinge piece 14, and the inner plate 12 is strongly pushed downward with a fingertip. Then, the fitting pin 30 is press-fitted into the fitting hole 36, the fitting pin 30 elastically overcomes the narrowed part of the fitting hole 36, and the fitting pin 30 is pressed into the fitting hole 36.
The pin 30 is fitted into the innermost circular part of the pin 6 with sufficient strength. At this time, the hinge piece 14
The positioning part 34 (including the action part 38b of the lever 38) is correctly accommodated in the positioning recess 28 of the inner tray 12. In this state, the inner plate 12 does not shake relative to the hinge piece 14, and the inner plate 12 and the hinge piece 14 become integrally rotatable about the hinge shaft 18.

When attaching the inner plate 12 to the hinge piece 14 as described above, the inner plate 12 is pressed from above to the lower side toward the hinge piece 14, but the force at this time is applied to the container main body 10 as a pedestal. Since it can be received by the hinge shaft 18, unreasonable force is not applied to weak parts such as the hinge shaft 18.

When removing the inner plate 12 from the hinge piece 14, as shown in FIG. 4, open the lid 16 completely, press the operating part 38a of the lever 38 with your fingertip,
This is rotated around the lever pin 40.
When the lever 38 rotates, the action portion 38b swings upward, pushing upward the rear end portion of the inner plate 12 that was in contact with the upper surface of the action portion 38b. This force releases the elastic fit between the fitting hole 36 and the fitting pin 30, and the inner plate 12 is separated from the hinge piece 14, resulting in the state shown in FIG. 5.

In this configuration, even if the lever 38 is strongly pressed with a fingertip, the inner plate 12 can be smoothly removed from the hinge piece 14 without applying excessive force to other weak parts such as the hinge shaft 18.

Note that the relationship between pins and holes or concave and convex portions of the fitting portion between the inner plate 12 and the hinge piece 14, and the shape thereof are not limited to the illustrated embodiment. Similarly, the shape of the lever 38 and the lever 38 are
The shape of the portion that acts to push the rear end of 2 upward is also not limited to the embodiment.

<<Effects of the invention>> As explained in detail above, in the compact container according to this invention, the strength of the fit between the inner plate and the hinge piece is made sufficiently strong to prevent play between the two. However, by pressing the inner plate against the fitting part of the hinge piece from above, they can be easily fitted together, and by pressing the lever provided on the hinge piece, the inner plate can be removed from the hinge piece. It can be easily removed, and when doing so, there is no need to apply excessive force to the hinge part and accidentally damage it, as was the case with conventional products, and the inner plate may suddenly come off and cause the cosmetics to scatter. This greatly improves the operability of replacing the inner tray.
In addition, the fact that the inner plate and hinge piece can be easily attached and detached even if the strength of the fit between the inner plate and the hinge piece is sufficiently increased means that the molding accuracy of the fitting part between the inner plate and the hinge piece does not need to be very high. Therefore, the incidence of defective products can be reduced and the price of the product can be lowered.
