Description

[Detailed description of the invention] [Field of industrial application] The present invention is applied to the lid of a container containing cosmetics, medicines, etc., and more specifically, the invention is directed to a positioning container that can be reliably and stably aligned with the container body. It concerns the lid.

[Prior Art] With the diversification of cosmetics in recent years, various designs of containers for storing cosmetics have been proposed. In particular, alignment containers are used when the container body and lid are formed with letters, figures, labels, etc., or when the cross-sectional shape is oval or polygonal. Since the lid can be locked in the closed state, it is useful for increasing the commercial value of cosmetics.

1 to 3 show an example of the structure of a conventional alignment container of this type. this is,
As shown in FIG. 1, on the outer periphery of the proximal end of the mouth 2 of the container body 1, there is a flat surface 3a orthogonal to the spiraling direction of the mouth 2 and an arcuate surface 3 that gradually becomes lower in the spiraling direction.
A pair of locking protrusions 3, each having a diameter b, are provided on the lower outer periphery of the lid 4 that covers the mouth portion 2, and are engaged with the flat surface 3a of the locking protrusions 3 to hold the lid 4 in a desired closed position. A frame body 6 having a locking piece 5 is fitted therein. As shown in FIG. 3, the locking piece 5 of the frame 6 has an arm piece 7 projecting from the locking piece 7 extending in the direction in which the lid 4 is screwed in. At the tip of the arm piece 7, the locking protrusion 3 A claw piece 8 is provided which pinches between the locking piece 5 and the locking piece 5. As shown in FIG. 1, the lid 4 is positioned in the closed position when the locking piece 5 of the frame 6 and the locking protrusion 3 of the container body 1 engage with each other, and the claw piece 8 is the circular arc surface 3 of the locking protrusion 3
The action of pressing b prevents loosening and rotation. In addition, to supplement the explanation about the lid 4, the lid 4 includes an inner lid 9 that is screwed onto the opening 2 of the container body 1, and a regular square shape formed to match the shape of the container body 1. It has a double structure in which the outer cover 10 is integrated with the outer cover 10. As shown in FIG. 2, these are assembled by fitting the inner cover 9 into the frame 6 and attaching the flange plate of the inner cover 9 to the annular ridge 11 protruding from the inner peripheral surface of the upper end of the frame 6. 12 and the inner cover 9 together with the frame 6 is attached to the outer cover 1.
0, and the frame body 6 and the outer cover 10 are fixed by adhesive or other means.

However, such conventional alignment container lids have the following problems.

First, since the claw piece 8 that prevents the lid 4 from loosening and rotating is formed at the tip of the arm piece 7 that protrudes from the locking piece 5 of the lid 4, the proximal end of the arm piece 7 is The parts are subject to repeated stress, which tends to cause fatigue, and as a result, there is a risk that the locking function will not work reliably. In addition, since there is a large molding error in a glass container body, a structure in which the arm piece 7 extends from the locking piece 5 in the screwing direction of the lid 4 cannot tolerate this error and the locking is difficult. Stopper 5
There is also a problem in that the locking protrusion 3 is sandwiched between the arm piece 7 and the claw piece 8 at the tip of the arm piece 7, making it impossible to prevent the lid 4 from loosening and rotating.

Secondly, when the lid 4 is placed over the mouth 2 in use, there is a high possibility that the arm 7 will hit the upper end of the mouth 2, and if the arm 7 is supported at one end, the mouth If it hits item 2, it may become deformed or even break.

Thirdly, there is a difficulty in assembling workability. That is, the inner lid 9 constituting the lid 4 is fitted until the flange plate 12 thereof comes into contact with the annular ridge 11 of the frame body 6, as shown in FIG.
Since the locking piece 5 and the arm piece 7 are formed protruding from the inner peripheral surface of the frame body 6, it is difficult to fit the frame body 6 and the inner lid 9 together.

[Purpose of invention]

The present invention was developed in view of these circumstances, and its purpose is to prevent the function of the pressing piece that prevents the lid from loosening and rotating from deteriorating in its function as an elastic member, and to allow for dimensional errors in the container body, etc. It is an object of the present invention to provide a lid for a positioning container which has a simple structure and can improve assembly workability without the risk of the pressing piece being deformed during use.

This frame body 23 is made of a hard synthetic resin with excellent wear resistance and elasticity, such as Diuracon, and is formed into a square frame shape corresponding to the shape of the inner peripheral surface of the outer lid 22. A locking piece 30 is provided on the inner circumferential surface in a protruding manner to prevent the lid 20 from rotating by engaging with the locking protrusion 3 when the lid 20 is screwed onto the container body 1, as in the conventional case. Further, at a position facing the locking projection 3 of the frame body 23, a pressing portion 31 is provided which contacts the locking projection 3 and restricts the return rotation of the lid 20. The pressing portion 31 is formed by curving a portion of the frame 23 inward. Furthermore, to explain this pressing part 31, 90 degrees from two opposing sides 23a, 23a of the frame 23 provided with the locking piece 30
On the two shifted sides 23b, 23b, a flat plate part 31a is formed with a part curved inwardly from approximately the center thereof to the vicinity of the locking piece 30, and a part of this flat plate part 31a is further curved inwardly. The contact portion 3 curves toward the

Further, in FIG. 7, the reference numeral 34 indicates a gasket, and this gasket 34 is fitted into a through hole 35 provided in the ceiling surface 21a of the inner lid 21, and in order to improve the sealing performance, the gasket 34 is A ring 36 is attached.

Further, on the lower surface of the flange portion 25 of the inner lid 21, a low-height guide ridge 40 is formed in an annular shape along the inner circumferential surface of the frame body 23 to restrict inward movement of the frame body 23. ing.

The lid 20 has a flange 2 of the inner lid 21.
An elastic protrusion 50 is provided at a position facing the outer peripheral surface of the pressing portion 31 of the frame 23 on the lower surface of the frame 23 . This elastic protrusion 50 is a feature of this embodiment.
It has a cylindrical shape that projects integrally with the flange portion 25, and is designed to facilitate the outward movement of the pressing portion 31 of the frame body 23 when the pressing portion 31 of the frame body 23 moves outward. It's summery.

Hereinafter, the lid 2 of this embodiment configured as described above will be explained.
The functions and effects of 0 will be explained.

In order to put the lid 20 into the assembled state shown in FIG. After attaching the frame 23, the fitting rib 32 of the frame 23 and the fitting groove 2 of the outer cover 22 are connected.
8. Note that, if necessary, the outer cover 22 and the frame body 23 may be fixed by ultrasonic welding or ordinary fixing means such as adhesive.

These assemblies include the outer cover 22, the inner cover 21,
It is a simple task of fitting the frame 23 in order,
The assembly process does not take much time, and it is possible to reduce costs and improve productivity.

The operation of screwing (covering) the lid 20 onto the container body 1 is the same as that for lids of containers with general threads. That is, the lid 20 is placed over the mouth 2 of the container body 1 and rotated in the tightening direction (rightward in the example in the figure). As a result of this operation, the gasket 34 comes into contact with the upper end of the mouth portion 2 to form an airtight state, and as the gasket 34 is elastically deformed, the resistance force against the rotational operation begins to increase.

When the lid 20 is further rotated against this resistance force, the pressing part 31 of the frame 23 of the lid 20 comes into contact with the locking protrusion 3 of the container body 1, and as the lid 20 rotates, the opening It is elastically deformed in the direction away from the axis of the portion 2, climbs over the locking projection 3, and then the locking piece 30 engages with the flat surface 3a of the locking projection 3, as shown in FIG. The pressing portion 31 presses the arcuate surface 3b of the locking protrusion 3 by its elastic biasing force.
Press the As a result, the screwed lid 20 is
At the same time as screwing is completed, the container body 1 is positioned and prevented from returning, and the outer circumferential surface of the container body 1 and the outer circumferential surface of the lid 20 are flush with each other.

At this time, the pressing portion 31
Since a part of 3 is curved, its elastic force can be increased, and therefore elastic fatigue or plastic deformation does not occur with use, allowing it to perform its functions for a long time. be able to. Further, the pressing portion 31, which requires elastic deformation and wear resistance, is formed by curving a part of the frame 23, and only this frame 23 is connected to other members (inner lid 21, outer lid 22, etc.). ), for example, a hard synthetic resin material such as Diuracon, the elastic deformation effect can be improved and wear of the pressing part 31 can also be reduced.

In addition, in use, when the lid 20 is placed over the mouth part 2, there is a possibility that the pressing part 31 comes into contact with the mouth part 2; Therefore, even if it hits the mouth part 2, there is no risk of it being damaged or deformed.

In this embodiment, since the guide protrusion 40 is formed along the inner circumferential surface of the frame 23, the frame 23 can be easily attached.
Opposing pieces 23a, 23a, 23 of the frame 23
b, 23b can be restricted from moving inward. That is, the frame 23 is fitted into the outer lid 22 with consideration of the end point of the screwing of the lid, but the shape of the inner circumferential surface of the frame 23 is preliminarily marked on the lower surface of the flange 25 of the inner lid 21. By forming the guide protrusion 40 along the guide edge 40, the frame body 23 can be easily aligned. Even if the frame body 23 is fitted into the frame body 23, there is no risk that the frame body 23 will shift during the operation. Furthermore, due to the structure in which the pressing part 31 is formed by curving a part of the frame 23, this pressing part 3
1 is pushed outward by the locking protrusion 3 of the container body 1, the two sides 23 with this pressing part 31
The other two sides 23b, 23 shifted by 90° from a, 23a
There is a possibility that b may shift inward, but since the guide protrusion 40 restricts this movement, there is no risk of this, and more reliable and stable positioning can be achieved.

In particular, in this embodiment, when the pressing part 31 of the frame body 23 is pushed out to the maximum extent by the locking protrusion 3 of the container body 1, this pressing part 31 is pushed inwards by the elastic projection 50. This has the effect of reducing fatigue of the pressing portion 31 due to repeated use. Due to this effect, the effect of preventing the occurrence of elastic fatigue, plastic deformation, etc. of the flat plate part 31a, which is obtained by forming a support structure in which the flat plate part 31a of the pressing part 31 is continuous with the peripheral wall part of the frame body 23 at both ends, is further ensured. It can be done. As a result, it is possible to reliably achieve long-term performance of the pressing part 31 as an elastic member without reducing its function, and to further improve the durability of the pressing part 31 and, by extension, the lid of the alignment container. can.

Further, the above-described pressing portion 31 is formed on the frame 23 separate from the outer lid 22 and the inner lid 21, and the elastic protrusion 50 is located at a position where it does not get in the way of the outer peripheral surface of the pressing portion 31 of the frame 23. When assembling the lid, the outer lid 22 must be
The inner cover 21 and the frame body 23 can be simply fitted in this order into the inner lid 21 and the frame body 23 in this order, which requires no time and effort to assemble, and it is possible to improve productivity and reduce costs.

Moreover, the flat plate portion 3 constituting the above-mentioned pressing portion 31
1a forms a part of the peripheral wall of the frame 23 and is supported at both ends, and
Since the elastic protrusion 50 is provided at a position facing the outer peripheral surface of the pressing part 31 of the frame body 23, even if the flat plate part 31a hits the mouth part 2 of the container body 1 when the lid is used,
It is said that the flat plate part 31a will not bend or break due to plastic deformation, and the elastic protrusion 50 will not be damaged, and the function of the pressing part 31 during use will not be impaired. There are advantages.

Next, FIG. 8 and FIG. 9 show the second part of the present invention.
An example will be explained.

This is the inner cover 21 of the first embodiment described above, that is, the inner cover 21 has the elastic protrusion 50 that urges the pressing part 31 of the frame body 23 inward, and the decorative flange plate 3.
The lid 20a is constructed by combining the frame body 23 with the number 7. With this kind of configuration,
Stable positioning can be achieved by utilizing the advantages of each component.

[Effect of idea]

As explained above, according to the present invention, the following excellent effects can be achieved.

(a) A state in which the pressing part for applying an elastic force to restrict loosening and rotation of the lid has a part of the peripheral wall forming the frame that faces the locking protrusion protruding inward of the frame in a band shape. It consists of a belt-shaped flat plate part configured by providing a flat plate part, and a contact part where a part of this flat plate part curves inward to press against the arcuate surface of the locking protrusion, and the elasticity of the pressing part is substantially reduced. The deformable part (flat plate part) has a support structure at both ends that is continuous with the peripheral wall part, and the position facing the outer circumferential surface of the pressing part of the frame in the inner lid allows the outward movement of the pressing part to be well controlled. Since the elastic protrusion is provided, when the pressing part of the frame is pushed wide to the maximum by the locking protrusion of the container body, this pressing part is urged inward by the elastic protrusion, This has the effect of reducing the fatigue of the pressing part due to repeated use, and due to this effect, elastic fatigue and plasticity of the flat plate part obtained by forming a support structure at both ends where the flat plate part of the pressing part is continuous with the peripheral wall part as described above is achieved. The effect of preventing occurrence of deformation etc. can be further ensured. As a result, it is possible to reliably achieve long-term performance of the pressing part as an elastic member without degrading its function, and it is possible to further improve the durability of the pressing part and, by extension, the lid of the alignment container.

(b) The flat plate part is provided with a contact part that curves further inward and presses against the arcuate surface of the locking protrusion, so that when the lid is in the closed position, the contact part The contact part is pressed by the elastic force of the flat plate part and comes into contact with the arcuate surface of the locking protrusion of the container body, and as a result, the elastic force of the flat plate part is concentrated on the contact part, and the lid is closed. Return rotation can be reliably prevented.

(c) A pressing part consisting of a flat plate part and a contact part that performs the above-mentioned functions is formed on a frame separate from the outer lid and the inner lid, and the elastic protrusion is formed by the pressing part of the frame. It is located in a position that does not get in the way and faces the outer circumferential surface of the lid, and when assembling the lid, it is a simple operation of fitting the inner lid and the frame into the outer lid in that order, making the assembly easier. It requires less time and effort, improves productivity, and reduces costs.

(d) Moreover, in the present invention, the flat plate part constituting the pressing part is supported at both ends so as to constitute a part of the peripheral wall part of the frame body, and the elastic protrusion is formed by the frame body. Because it is located at a position facing the outer peripheral surface of the pressing part, even if the flat plate part hits the opening of the container body when the lid is used, the flat plate part will not be plastically deformed and bent or broken. Furthermore, there are advantages in that the elastic protrusions are not damaged and the function of the pressing part is not impaired during use.
