Description

[Detailed description of the invention] "Industrial application field" This invention is a compact container for cosmetics, for example, in which a lid body for opening and closing the top surface of the container body is pivotally attached to the rear part of the container body. The present invention relates to a container in which the lid is elastically inverted when opened and closed.

``Prior Art'' Compact containers for cosmetics generally have a rear part of the lid that opens and closes the top of the container body pivoted to the rear part of the container body.
There are known types in which the lid is biased toward the container body in a closed state by attaching a spring to the pivot portion, and types in which the lid is not biased.

Caps with elastically reversible lid plates are also known, and the following caps are known as such caps.

That is, grooves with upper and rear openings are vertically provided in the rear upper part of the peripheral wall of the cap body that fits into the container mouth neck, and the upper half is bent forward from the lower edge of the groove via the second hinge. A flat spring that does not curve is made to stand up by removably fitting the lower part of the flat spring into the groove, and the front end of the flat spring is opened with its lower end surface in the latter half of the small lid that covers the top wall of the cap main body. The leaf spring part is fitted into the long hole through the third hinge to the front end edge of the vertically installed long hole, and the leaf spring part is connected to the front edge of the long hole. They are integrally connected via a first hinge, and a stopper hanging from the back surface of the small lid is removably fitted into an outflow hole formed in the top wall of the cap main body.

In this configuration, when the small lid is rotated rearward and upward with respect to the cap body around the first hinge, the leaf spring is elastically deformed and then elastically restored, and the small lid opens with respect to the cap body, and returns to this state. When the front part of the small lid was pushed forward, the leaf spring was elastically deformed and returned to its original state, and the plug of the small lid was formed to close the outflow hole in the top wall of the cap body.

``Problems to be solved by the invention'' The above-mentioned cap with a leaf spring is used as a cap for containers containing shampoo, etc., and is suitable as a relatively small cap. It is difficult to apply it to compact containers etc.

In the present invention, for example, the lid of a compact container or the like is formed to be elastically reversible.

"Means for Solving the Problems" In a container in which the rear part of a lid 14 that can open and close the upper surface of the container body is pivotally attached to the rear part of the container body 1, from both left and right sides of the rear upper surface of the container body,
A pair of left and right elastic arms 12 curved in an almost arc shape,
12 protrudes rearward and upward, and shafts 13, 13 protruding from the tips of the arms are attached to the shaft holes 1 of bearings 15, 15 attached to both left and right sides of the lower rear surface of the lid body.
6, 16, and when the lid is rotated relative to the container body around the shafts 13, 13, the rear end of the lid slides into pressure contact with the upper surface of the container body so that it can be elastically reversed.
The distance from the shafts to the rear end 14a of the lid body is made larger than the distance from the shafts 13, 13 to the upper surface of the container body, and the elastic arms with shafts and bearings are provided inside the peripheral wall 18 of the lid body so that the lower surface of the peripheral wall is It was brought into contact with the upper surface of the outer periphery of the container body.

"Function" Elastic arms 12, 12 that curve approximately in an arc shape and protrude rearward and upward from both the left and right sides of the rear upper surface of the container body.
Since the shafts 13, 13 at the tip are fitted into the shaft holes of bearings 15, 15 attached to the left and right sides of the rear lower surface of the lid body 14, the shafts 13, 13 are also closer to each other than the distance to the top surface of the container body. Since the distance from the rear end of the lid to the rear end of the lid is large, as the lid rises and the rear end of the lid slides into pressure contact with the top surface of the container body, the positions of the shafts 13, 13 and the bearing 15 rise, and the elastic arm 12,
12 is raised against its elasticity, and when the rear end of the lid passes forward below the shafts 13, 13 as shown in FIG. 1B, the elastic arms 12, 1 pass through the dead center.
2 is elastically restored, and the outer surface of the lid peripheral wall 18 is brought into pressure contact with the upper surface of the container main body, as shown in FIG. By pushing the front part of the lid forward from this state, it is elastically inverted again and the lid closes the top surface of the container body.

``Example'' Taking a compact cosmetic container as an example, the container body 1 has a lower box 4 with a peripheral wall 3 standing up from the periphery of a bottom wall 2, and a storage section 5 for cosmetics etc. fitted into the lower box. It is formed with an upper wall plate 6. The upper end surface of the peripheral wall 2 and the upper surface of the upper wall plate 6 are flush with each other. The front part of the lower box is inserted inward, and a first engager 7 for engaging the lid is attached to the front face of the inner part, and pins 8, 8 are protruded from both left and right end surfaces of the insertion part, and the pins are inserted into the front part of the lower box. It is provided so that it can be fitted into pin holes 10, 10 on both end faces of the oscillator 9 to be fitted into the insertion portion.
Further, a notch 11 into which the above-mentioned insertion part fits is also provided in the front part of the upper wall plate.

From the left and right sides of the rear upper surface of the upper wall plate 6, elastic arms 12, 12, which are curved in an almost arc shape, protrude rearward and upward, and from the tip of the arm, a shaft 13,
13 protrudes outward on both the left and right sides.

A lid 14 opens and closes the upper surface of the container main body, and has bearings 15 on both left and right sides of its lower surface. Shaft holes 16, 16 are bored in the bearing to rotatably fit the aforementioned shafts 13, 13, and holes 16, 16 are formed from the front part of the lid body to engage with the lower surface of the aforementioned first engager. A plate 17 with a second engaging element is vertically provided, and when the lid is closed, the plate projects rearward from the lower rear surface of the oscillator 9 by pushing the lower front surface of the oscillator 9 downward and rearward. A portion is provided so as to push up the plate 17 with the second engaging element to disengage the first and second engaging elements.

1A, the distance from the shafts 13, 13 to the rear end 14a of the lid 14 is set to be greater than the distance from the shafts 13, 13 to the upper surface of the container body 1. Also, the lower surface of the peripheral wall 18 of the lid is placed in contact with the upper surface of the outer periphery of the container body.

The lid peripheral wall 18 may be formed as an inclined surface sloping downward and outward, as shown in the figure. In this way, when the lid is opened, as shown in Figure 1C, the rear inclined surface comes into surface contact with the upper surface of the container body, preventing the lid from moving blindly in this state.

"Effect of the invention" The present invention has the above-described structure, in which a pair of left and right elastic arms 12, 12 curved in an almost arc shape are protruded rearward and upward from both left and right sides of the rear upper surface of the container main body.
Since the elastic reversal of the lid body 14 is performed against the elasticity of both elastic arms, the lid body 14 is larger than the elastically reversible lid plate of the cap described above, such as the lid of a compact container. In addition, the elastic arm is curved in an arc, and the distance from the shaft to the rear end of the lid body is larger than the distance from the shaft 13 to the top surface of the container body, so that the lid can be bent around the shaft. When the body rotates, as the rear end of the lid approaches the lower part of the shaft 13, the shaft 13 is pushed up, and at the same time as the rear end of the lid passes below the shaft, the elastic arm elastically restores and the lid is elastically reversed. Therefore, by setting the elastic arm to an appropriate length, the elastic deformation of the elastic arm will not become excessive and damage will occur. Since the container body is brought into contact with the upper surface of the outer circumferential portion of the container body, the pivoting portion between the container body and the lid body is hidden inside the container, thereby improving the appearance of the container.
