Description

[Detailed description of the invention] The present invention relates to a compact container for storing cosmetics such as white powder, and its purpose is to easily open and close the container while reliably maintaining the lid closed state. It is.

Compact containers are required to be small and thin so that they can be conveniently carried in a band bag, etc., especially when used for makeup on the go, and the lids do not open due to vibrations while being carried. It is necessary to ensure that the lid remains closed.

However, on the other hand, it is desirable to be able to open and close the container with a simple operation, and since the container is thin, it is particularly difficult to open the lid, and the container often slips out.

The present invention was devised in view of the above-mentioned requests, shortcomings, and inconveniences regarding compacts, and the inner case body, which stores cosmetics in the thin box-shaped outer case body, is moved slightly back and forth through an elastic material. The front end of the lid, which is pivotably attached to the rear end of the outer case body, is engaged with the front end of the inner case body, and the inner case body is pushed backward against elasticity to achieve the above engagement. The lid is opened by releasing the lid, and one embodiment thereof will be described below with reference to the drawings.

In the drawings, reference numeral 1 denotes an outer case body made of synthetic resin, which is composed of a bottom plate 2, side walls 3, 3, and a rear wall 4, and is shaped like a thin box with an open top and front surface.

A lid 14 made of synthetic resin is pivotally attached to the rear end of the outer case body 1 so that it can be opened and closed in a book-like manner. In the assembly, the plates 15 are pivoted to face both outer side surfaces of the rear end of the outer case body 1, hanging down from both ends of the outer case body 1.

Furthermore, inside the outer case body 1, a flat synthetic resin inner case body 9, which has a circular recess 10 in the center of the upper surface into which a cosmetic storage drum is inserted, is assembled so as to be movable in the front-rear direction. There is.

An elastic member 11 is provided between the inner case body 9 and the outer case body 1, and the elastic member 11 is connected to the inner case body 9 at one end and to the outer case body 1 at the other end. The closed position is maintained by engaging an engaging protrusion 18 provided on the lower surface of the front end with an engaging groove 13 provided on the front end of the upper surface of the middle case body 9.

The inner case body 9 is assembled into the outer case body 1 so as to be displaceable in the front-rear direction, and there are various methods for assembling the inner case body 9 to the outer case body 1.

For example, a guide groove is provided horizontally in the front-rear direction on the inner surface of both side walls 3, 3 of the outer case body 1, and a protrusion provided on the side surface of the inner case body 9 along the front-rear direction is engaged with this guide groove. Thus, the inner case body 9 can be assembled to the outer case body 1 in such a manner that it can be displaced only in the front-rear direction and cannot be displaced upwardly.

At this time, if projecting pieces are provided on the front ends of both side walls 3, 3 of the outer case body 1, respectively, with which the front side ends of the middle case body 9 abut, the middle case body 9 is moved forward from inside the outer case body 1. It is possible to reliably prevent the extraction of the

Moreover, the bullet 11 is in a form that can apply a forward pressing force to the middle case body 9 between the rear end surface of the middle case body 9 and the outer case body 1, and has one end attached to the middle case body. 9, the other end is connected to the outer case body 1, and is not necessarily integrally molded to either the outer case body 1 or the inner case body 9.

In the case of the illustrated embodiment, a frame plate 8 is provided on the upper surface of both side walls 3°3 of the outer case body 1, with a portion thereof protruding inwardly, over almost the entire length of the side wall 3.
In contrast, the inner case body 9 is assembled so that it can be slid only in the front-back direction.

Further, a U-shaped bullet 11 is integrally provided on the rear end surface of the middle case body 9, and the rear wall 4 of the outer case body 1 is located at the rear part of the outer case body 1 opposite to this bullet 11. A recessed chamber 5 is formed in the center of the recessed chamber 5 with a depth that allows the bullet 11 to enter the position with sufficient margin.

That is, the central portion of the rear wall 4 is shaped to protrude rearward, forming a recessed chamber 5 therein.

In the center of the top plate 6 of the recessed chamber 5, which has a depth that allows the bullet 11 to enter with a margin, there is a narrowest constriction that tapers from a wide opening 7a located at the front edge of the top plate 6. 7b, a notch 7 having a wide circular hole 7c is formed, and with respect to this notch 7, both side plate portions 11a and rear plate portion 11b, which constitute the elastic material 11, are formed. A pin 12 is protruded from the center of the upper end surface of the rear plate portion 11b, which functions as an elastic member, and is fitted into the hole 7c of the notch 7 so as not to be pulled out forward.

That is, the elastic material 11 is integrally formed with the inner case body 9.
When the inner case body 9 is assembled into the outer case body 1 by fitting the pin 12 into the hole 7c of the notch 7 of the recess 5 of the outer case body 1, the pin 12 is pulled out from the hole 7c. does not come out, and there is sufficient space between the rear end of the bullet 11 and the rear surface of the recessed chamber 5 at the position where the pin 12 is fitted into the hole 7c.
The inner case body 9 can be displaced in the front-rear direction with respect to the outer case body 1 within the range of elastic deformation of the elastic material 11, and the elastic material The inner case body 9 can be moved forward beyond the forward limit position regulated by the elastic deformation range of the inner case body 11, and therefore the inner case body 9 is retained attached to the outer case body 1 in such a manner that it cannot be pulled out.

In short, the elastic member 11 with the pin 12 attached to the hole 7c in a manner that is not removable can exert a forward pressing force on the inner case body 9, and also exert a forward pressing force on the outer case body 1 of the inner case body 9. This restricts the range of displacement along the front-rear direction, thereby preventing the inner case body 9 from being pulled out forward from the outer case body 1.

In addition, in the closed state, the lid body 14 makes the lower surface of the top plate 16 face the upper surface of the frame plate 8 of the outer case body 1 and the upper surface of the top plate 6 of the recessed chamber 5, and the lower surface of the peripheral wall 17 faces the upper surface of both side walls 3, 3 and the middle surface. The upper front end of the case body 9 is configured so as to seal the cosmetic storage drum assembled to the inner case body 9, and the means for holding the lid body 14 in the closed state is In the case of the illustrated embodiment, a retaining protrusion 18 whose vertical cross section is in the shape of a truncated right triangular pyramid is projecting downwardly from the lower surface of the center of the front end of the top plate 16. A protrusion 18c is provided on the tab portion, and an engagement groove 13 into which the engagement protrusion 18 can enter is recessed in the center of the front end of the upper surface of the inner case body 9. Vertical surface 1 which is the groove surface on the rear side of the groove 13
3b is provided with a protrusion 13c which the above-mentioned protrusion 18c rides over and locks from below, and this circumferential protrusion 13c
The closed state of the lid body 14 is maintained by the engagement between the lid body 18c and the lid body 18c.

Note that the gentle slope 3a, which is the groove surface on the front side of the engagement groove 13, and the gentle slope 18a, which is the front surface of the assembly root 15, are the groove surface on the front side of the engagement groove 13.
When the protrusion 8 is inserted into the engagement groove 13, the lower end of the engagement protrusion 18 acts to guide the insertion operation, and when the protrusion 18c is engaged with the protrusion 13c from below, the lower end of the engagement protrusion 18 is inserted into the engagement groove. By setting the dimensions of the engagement protrusion 18 and the engagement groove 13 so that they come into contact with the bottom surface 13d of the protrusion 13, the engagement between the protrusions 13c and 18c can be made more stable.

When the engagement protrusion 18 fits into the engagement groove 13, the position of the inner case body 4 relative to the outer case body 1 is approximately at the forward limit position or a position slightly retracted from this forward limit position. It is preferable to do so.

This is because when both protrusions 13c and 18c are locked, the pressing force from the bullet material 11 is acting on the middle case body 4, and the vertical surface 1
3b is pressed against the vertical surface 18b,
In such a state, unless the inner case body 4 moves backward against the elasticity of the bullet 11, both protrusions 13c, 18c
This is because there is no risk that the lock will be released and the lid body 14 will be opened unnecessarily.

In the case of the illustrated embodiment, the middle case body 9 is assembled to the outer case body 1 by simply fitting the middle case body 9 into the outer case body 1 from the front open end, and inserting the pin 12 into the notch 7. , by forcibly fitting it into the hole 17c.

Since the present invention has the above-described configuration, the inner case body 9 can be opened by rotating the lid body 14 in the same way as a normal compact.
By pressing upward, both protrusions 13c and 18c are locked, resulting in a closed state.

Both protrusions 13c and 18c are locked when the middle case body 9 is
Since it is receiving the forward pressing force from 1, it is ensured that the closed position of the lid body 14 is ensured.

To open the compact from this state, apply pressing force with your fingertips to the front end surface of the middle case body 4 exposed from the outer case body 1, and push the middle case body 9 against the elasticity of the bullet material 11. It is better to move it backwards.

When the middle case body 9 is displaced backward, both protrusions 13C? 18
C is released, and the lid body 14 is opened as it is.

In this way, the compact according to the present invention has an outer case body 1
Since the closed state of the lid body 14 is released by moving the inner case body 9 provided inside the case body 9 back and forth, the closed state of the lid body 14 can be reliably and strongly moved. To open the body 14, move the inner case body 9 to the outer case body 1 with your fingertips.
The operation is easy because it can be operated with one hand while holding the compact.

Furthermore, the displacement range of the middle case body 9 in the front-rear direction with respect to the outer case body 1 is restricted by the elastic member 11 provided to apply a forward pressing force to the middle case body 9. The structure for regulating the displacement range of the inner case body 9 is simplified, and thereby the structure for mutual assembly of the outer case body 1 and the middle case body 9 can be made simpler.

As is clear from the above description, the compact according to the present invention can strongly and reliably maintain the closed state, is easy to open, and has a simple structure and is easy to mold and assemble. It has excellent effects.
