Description

[Detailed description of the invention] This invention provides a hinge mechanism at each rear end of the container body and the lid, which are made by fitting an inner tray filled with cosmetics from above, and connects them so that they can be opened and closed. This relates to a compact container that can be opened with a single touch operation.

Conventional compact containers of this type have a push piece attached to the edge of the container body or lid, and by pushing the push piece inward, the closing engagement between the lid and the container body is released, and the lid is closed. It has become publicly known that the system can be opened.

However, in such known compact containers, the opening angle of the lid that is opened by pushing the push piece is small, so especially in thin compact containers, when you try to open the lid with your thumb, the tip of your thumb may Since it also touches the edge of the container body, it has not been easy to open the lid at a desired angle.

For this reason, the applicant first elastically deformably supports a leaf spring on the rear end edge of the container body, integrally forms a projecting piece on the rear end of the lid body corresponding to this leaf spring, and When the body is closed, this protruding piece presses and deforms the leaf spring, and when the push piece is pushed in, the lock of the lid body is released, and at the same time, the lid body is opened to a predetermined angle by the action of this leaf spring. The company provided a compact container designed to

However, in the compact container according to this prior application, the amount of elastic deformation of the leaf spring and the opening angle of the lid are in a proportional relationship, so in order to open the lid wide, the amount of elastic deformation of the leaf spring becomes large. When the lid is unlocked, the lid suddenly opens wide, which surprises the user and leaves room for improvement.

The present invention is an improvement over the above-mentioned compact containers, and its object is to provide a compact container having a large lid that can be opened relatively slowly and smoothly.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 indicates the container body, and the container body 1
Both edges of the rear end are partially cut out to form a concave cutout 2-2.
A hinge block 4-4, which is integrally formed to hang down from the rear end of the lid body 3, is inserted into this concave notch 2-2, and this block body 4-4 is connected to the pin 5-2.
5 is pivotally attached to the rear end wall of the container body 1, so that the lid 3 can be opened and closed with respect to the container body 1. A recess 6 is formed in the center of the front edge of the container body 1, and a first engaging protrusion 7 is integrally provided on the inner surface of the recess 6. The lower part of the recess 6 is cut out inwardly, and the lower part of the slide member 8 is slidably engaged therein, and the upper surface of the slide member 8 has a tapered surface 9 that descends inward.
It is formed as. The lid body 3 has a mirror 10 attached to its inner surface, a claw piece 11 is suspended from the front edge, and a second engagement projection piece 12 is integrally formed on the inner surface of this claw piece 11. There is. When the lid 3 is closed, the second engaging protrusion 12 engages with the first engaging protrusion 7 formed on the container body 1 to occupy a closed position, and from this closed position the slide member 8 When the slide member 8 is pushed inward, the tapered surface 9 of the slide member 8 pushes up the claw piece 11 of the lid body 3, whereby the locking engagement of the first and second engaging protrusions pushes the slide member 8 up. The lid is released by a one-touch operation such as pushing inward.

In the first embodiment of the present invention, as clearly shown in FIGS. 2 to 4, a large recess 13 with a wide width is formed at the rear edge of the container body 1, and a pair of small recesses 14- 14 is formed separately, and a leaf spring 15 is dropped into this large recess 13 from above to form a partition protrusion 1 between a pair of small recesses 14-14.
A leaf spring 15 is supported on the upper surface of the spring 6. One side of the leaf spring 15, in the illustrated example, the right side piece 15a located above the small recess 14 on the right side is
It is formed thinner than other parts. An inner tray 17 filled with cosmetics is fitted into the container body 1 as described above from above, and the plate spring 1 is thereby fitted into the container body 1 as described above.
5 is designed to prevent it from accidentally deviating from the recess 13. At the rear end of the inner plate 17, there is a pair of notches 1 located directly above the small recess 14-14.
8-18 is formed. This notch 18-1
8, a pair of long and short protrusions 19a and 19b are integrally formed on the rear end wall above the hinge part of the lid body 3, and in the illustrated example, the right protrusion 19a is the same as the left protrusion. 19b, and when the lid body 3 is closed, these protruding pieces 19a-19b are longer than the notch part 18 of the inner plate 17.
-18 into the recess 13.

Now, when the lid 3 is closed from its open position, the protrusions 19a-19b formed on the rear end wall of the lid 3
passes through the notch 18-18 of the inner plate 17, and as shown in FIG. When the lid body 3 is further closed from this state, as shown in FIG.
b comes into contact with the left thick portion 15b of the leaf spring 15. When the lid body 3 is further closed from the state shown in Fig. 3,
Both protruding pieces 19a, 19b bend both sides 15a, 15b of the leaf spring 15 downward as shown in FIG.
The engaging protrusion 12 engages with the first engaging protrusion 7 formed on the front edge of the container body 1, and the lid 3 assumes the closed position. When the slide member 8 is pushed inward in the closed position of the lid 3, the first and second engaging protrusions 7, 1 of the container body 1 and the lid 3 are moved as described above.
2 is disengaged and the lid body 3 is opened, the leaf spring 15 elastically returns to the position where the protrusion 19 on the rear end wall of the lid body 3 is released.
and pushes it up, thereby lifting the lid 3.
is rotated about its pivot pin 5-5 in the opening direction. At this time, in the initial stage of opening, both sides 15a-15b of the leaf spring 15 are connected to both protruding pieces 1 of the lid body 3.
Since 9a-19b is pushed up, the elastic return force of the leaf spring 15 acts strongly (see FIG. 3). However, in the later stage of opening, only the thin piece 15a of the leaf spring 15 acts on the long protruding piece 19a of the lid body to push up the lid body, so the elastic return force of the leaf spring acting on the lid body is weak. It will gradually open up.

FIG. 5 shows the main parts of a compact container according to a second embodiment of the present invention, and in this embodiment, the container main body 1
A large recess 14 and a small recess 14b are formed inside the wide recess 13 formed at the rear end edge, and a uniform leaf spring 20 with a wall thickness slightly shorter than the width is dropped into the wide recess 13. The inner plate 17 is covered from above. Therefore, in this embodiment, the partition projection 16 between the two recesses 14a and 14b on which the leaf spring 20 is mounted and supported is offset from the center of the container body 1 toward the small recess 14b, The right side piece 20a of the leaf spring 20 extending from the partition protrusion 16 to the left side is longer than the left side piece 20b of the leaf spring 20 extending from the partition protrusion 16 to the left side. The other configurations are the same as in the first embodiment.

In the compact container according to the second embodiment, when the lid is closed, both long and short protrusions 19a-
19b presses and deforms both side pieces 20a and 20b of the leaf spring 15 downward, but the distance ₁ from the partition protrusion 16 to the point where the long protrusion 19a presses and deforms the right side piece 20a of the leaf spring 20 is longer. Since the distance 2 from the partition protrusion 16 to the point where the short protrusion 19b deforms the left side piece 20b of the leaf spring 20 by pressing is greater than the distance ₂ , the amount of deformation of the right side piece 20a of the leaf spring 20 is greater than that of the left side piece 20b of the leaf spring 20. It is more than that of piece 20b. Therefore, when the push piece is pushed in to open the lid 3, even after the elastic return of the left side piece 20b of the leaf spring 20 is completed, the right side piece 20a continues to elastically return, and the lid 3 is opened as in the first embodiment. 3 is released.

FIG. 6 shows a leaf spring 21 used in the third embodiment of the present invention, and this leaf spring 21 is inserted into a recess formed in the rear end edge of the container body 1 as in the first embodiment. It is. In this embodiment, the leaf spring 21
By narrowing the depth width of the right side piece 21a of the left side piece 2
It has weaker elasticity than 1b. Also in this embodiment, the longer protrusion 19a of the pair of protrusions integrally formed on the lid body 3 presses and deforms the right side piece 21a, and the shorter protrusion 19b presses and deforms the left side piece 21b. Then, the lid 3 is opened as in the first embodiment.

FIG. 7 shows a leaf spring 22 used in a fourth embodiment of the present invention, which has a left side portion 22.
2b is formed with a protruding semicircular rib 23 extending in the longitudinal direction, so that the left side piece 22b is connected to the right side piece 2.
The elastic return force is stronger than 2a. Also in this embodiment, the longer protrusion 19a of the pair of protrusions formed on the lid body 3 presses and deforms the right side piece 22a, and the shorter protrusion 19b presses and deforms the left side piece 22b. The lid 3 is opened as in the first embodiment.

As described above, in any of the embodiments of the present invention, the elastic force in the vertical direction of the leaf spring is made different on both sides, and the leaf spring is formed integrally with the lid when the lid is closed against the container body. The long protrusions press and deform the less elastic side of the leaf spring, and the short protrusions press and deform the more elastic side of the leaf spring. During the opening stage, both sides of the leaf spring act, but after that, only the less elastic side of the leaf spring opens the lid relatively slowly and widely, so the opening of the lid is not as sudden as in the past. It becomes smooth.
