Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a container whose lid can be opened and closed by pressing with a fingertip or the like.

``Prior Art'' Conventionally, in containers for storing cosmetic liquids such as milky lotions and lotions, the screwing between the male thread provided on the outer periphery of the opening of the container body and the female thread provided on the inner periphery of the lid body was performed using a lid body. The lid can be opened by turning and unscrewing it.

``Problem that the invention aims to solve'' With this type of container, the main body of the container can be held with one hand,
To open and close the lid by twisting it with your other hand,
Opening and closing the lid requires the use of both hands, and the lid must be turned several times by hand, which poses a problem in that it takes time to open and close.

This idea was proposed in consideration of the above points, and it can be easily opened and closed with one hand without turning the lid, and it can also be opened and closed by turning the lid like in the past. The purpose is to provide a new container that has both functions.

"Means for Solving the Problem" In order to achieve the above object, this invention provides a container consisting of a container body having a small-diameter mouth and a lid screwed onto the mouth of the container body. The lid includes an inner lid having a ring-shaped bottom plate, a flexible elastic ring set on the bottom plate of the inner lid so as to surround the mouth of the container body, and these are fitted inside. and an outer lid for storage, and on the inner peripheral edge of the bottom plate of the inner lid,
A cylindrical portion surrounding the mouth portion is integrally provided to protrude upward, and a pair of openings communicating with the inside and outside of the cylindrical portion are formed at mutually opposing positions of the cylindrical portion, and An elastic ring is inserted into the outer periphery of the cylindrical part so as to be elastically deformable, and a flexible annular part formed in a cylindrical shape concentric with the cylindrical part, and the opening on the inner periphery of the annular part. protrusions protruding from the opening at positions facing the opening and engaging with external threads provided on the outer periphery of the mouth portion; a pair of pressing parts protrudingly formed on opposing outer peripheries and elastically deforming the annular part in the radial direction to separate the projecting pieces from each other; The plate is formed along the advancing direction, has a plate thickness smaller than the height of the annular part, and has a length that fits in the opening, and the pressing part is attached to the side wall of the outer lid at the lower end of the side wall. The outer circumferential side of the outer lid is exposed from the openings provided in the open state.

"Operation" To assemble the lid, insert the annular part of the elastic ring around the outer periphery of the cylindrical part of the inner lid, expose the protrusion from the opening of the cylindrical part, and insert the opening of the outer lid into the elastic ring. The outer cover is inserted onto the inner cover in accordance with the pressing part, and the lower end of the outer cover and the bottom plate of the inner cover are attached by a method such as gluing.

In the lid assembled in this way, when the pressing part of the elastic ring is held between fingers or the like and pressed, the part of the annular part of the elastic ring where the pressing part is located deforms inward, and the circumference is 90 degrees above this part. The protruding portion of the protruding piece at the shifted position is deformed outward, and the protruding piece is held in a disengaged state with the external thread of the opening.

On the other hand, with the pressing part released, open the lid.
When inserted into the mouth of the container body and rotated in the circumferential direction, the protrusion protruding from the inner circumference of the annular part engages with the male thread of the mouth, and as it rotates, the protrusion rotates along the male thread. The lid is screwed into the mouth.

"Embodiment" Hereinafter, the first embodiment of this invention will be described with reference to FIGS. 1 to 4. The container of this invention will be described as follows.
The container body 1 is composed of a container body 1 in which a cosmetic liquid is placed, and a lid body 3 that is screwed onto a small-diameter opening 2 of the container body 1.

Then, the lid body 3, as shown in FIG.
It is composed of an inner cover 4, a flexible elastic ring 5, and an outer cover 6 that accommodates these inside.

The inner lid 4 is mainly composed of a ring-shaped bottom plate portion 7 that serves as the bottom plate of the lid body 3, and a cylindrical portion surrounding the mouth portion 2 of the container body 1 is provided at the inner peripheral edge of the bottom plate portion 7. A pair of openings 9, 9 are formed at opposing positions of the cylindrical portion 8 to communicate with the inside and outside of the cylindrical portion 8.

The elastic ring 5 includes a flexible annular part inserted into the outer periphery of the cylindrical part 8 and formed in a cylindrical shape concentric with the cylindrical part 8, and the opening on the inner periphery of the annular part. Projecting pieces 1 are arranged facing each other and protruding from the opening at positions facing 9 and 9, respectively, and are engaged with external threads 10 provided on the outer periphery of the mouth.
1 and 11, and are formed protrudingly on opposing outer peripheries of the annular portion at positions shifted by 90 degrees on the circumference from the protrusions 11 and 11, and the annular portion is elastically deformed in the radial direction to form the protrusions 11. , 11 from each other. As shown in FIG. 2, the projecting pieces 11, 11 are arranged along the threading direction of the male screw 10, have a thickness smaller than the height of the annular part, and are large enough to fit into the openings 9, 9. In the illustrated example, the projecting pieces 11, 1 having such a configuration are
1 is located above and below the inner periphery of the annular portion, and has a structure in which two protrusions are provided. And the elastic ring 5 is
The elastic ring 5 is set on the bottom plate part 7 of the inner cover 4 so as to surround the cylindrical part 8 and to be elastically deformable with a gap G necessary for the elastic ring 5 to slide between the cylindrical part 8 and the cylindrical part 8. In this state, the projections 11, 11 are inserted into the openings 9, 9 of the cylindrical portion 8 so as to be slidable in the radial direction of the cylindrical portion 8 (see FIG. 4).

Further, openings 14, 14 are formed in the side wall 13 of the outer lid 6, and the openings 14 reach the lower end and open.
A cylindrical hanging part 16 concentric with the side wall 13 is provided on the inner surface of the top plate part 15 of the outer lid 6, and a gasket 17 is provided inside the cylindrical hanging part 16.
is attached.

In order to assemble the lid body 3 as shown in FIG. is inserted into the outer periphery of the cylindrical part 8, and the openings 14, 14 of the outer lid 6 are inserted into the pressing parts 12, 1 of the elastic ring 5.
2, insert the outer cover 6 onto the inner cover 4, and
The lower end of the inner cover 4 is attached to the bottom plate 7 of the inner cover 4 by a method such as gluing.

This assembly is a simple process of inserting the annular part of the elastic ring 5 into the outer periphery of the cylindrical part 8 of the inner cover 4, setting the elastic ring 5 on the bottom plate part 7, and then covering and gluing the outer cover 6 over this. and the opening 14 of the outer lid 6,
14 is open at the lower end, so it can be inserted without being interfered with by the pressing parts 12, 12 of the elastic ring 5, and no techniques such as force-fitting are required when assembling it, improving workability. can be improved.

In the container constructed in this manner, when opening the lid 3, the pressing parts 12, 12 of the elastic ring 5 facing from the openings 14, 14 of the outer lid 6 are held between the thumb and, for example, the middle finger. The elastic ring 5 is bent, the protrusions 11, 11 are moved outward to disengage the opening 2 from the external thread 10, and the lid 3 is lifted as it is.
Therefore, the lid 3 can be opened by placing the container on, for example, a desk, pressing the pressing parts 12, 12, and then lifting the container with one hand. When closing the lid 3, the pressing parts 12, 12 of the elastic ring 5 are held between the thumb and, for example, the middle finger, and pressed inward to bend the elastic ring 5 and push the protrusions 11, 11 outward. If the inner lid 4 is fitted into the opening 2 of the container body 1 and the lid 3 is pushed down to release the pressing parts 12, 12 of the elastic ring 5, the protrusions 11, 11 of the elastic ring 5 will be removed. The external thread 10 of the mouth portion 2 is engaged and the lid body 3 is closed. Therefore, the operation of closing the lid body 3 can be easily performed with one hand.

Of course, the container body 1 can also be opened and closed by rotating the lid 3 in the conventional manner.

According to the container of the embodiment, the annular portion of the elastic ring 5 is formed into a cylindrical shape large enough to fit within the outer periphery of the cylindrical portion 8, and the height dimension of the annular portion is larger than the height dimension of the annular portion at opposing positions on the inner periphery. Since the protrusions 11, 11 have a small plate thickness and are long enough to fit into the opening, the protrusions 11, 11 are protruded, so that the annular portion is only slightly elastically deformed, and the protrusions 11, 11 and the male screw are connected. A sufficient amount of sliding movement of the protrusions 11, 11 necessary for releasing the engagement with the protrusions 11, 11 is ensured. Therefore, even if it is operated repeatedly, plastic deformation or elastic fatigue hardly occurs in the elastically deformed portion, and its function is stably exhibited for a long period of time.

Also, if we pay attention to the state when the engagement between the protrusions 11, 11 and the male screw is released, the pressing portion 12,
By the pressing operation by 12, the pressing part 1 of the annular part
As the part deviated by 90 degrees on the circumference from 2 and 12 deforms outward, the protruding piece 1 protrudes from the inner periphery of the part.
1 and 11 are spaced apart outwardly, the annular portion can be elastically deformed without causing distortion or other deformation to the protrusions 11, 11 that make up this screw, allowing for long-term use. Reliability as a screw can be maintained over a period of time.

In addition, since the protrusions 11, 11 are formed to have a plate thickness smaller than the height of the annular portion and have a length that fits in the openings 9, 9, the thickness corresponds to the pitch of the male thread. The height can be easily adjusted, and the applicability to various types of containers with different thread pitches at the mouth can be improved.

5 and 6 show a second embodiment of this invention, in which protrusions 11, 11 of the elastic ring 5 are placed inside the cylindrical portion 8 of the inner lid 4 at opposing positions. An opening for protruding into the (insertion hole 1 in the illustrated example)
8, 18 and insertion grooves 19, 19) are provided, and the inner stopper 22 is fitted into the mouth 21 of the container main body 20, while the inner stopper 22 is placed in a position facing the inner stopper 22 of the outer lid 6.
A protrusion 24 for closing the spout 23 of No. 2 and an annular rib 25 for pressing against the inner stopper 22 are provided. In a container having such a structure, the same effects as those of the above-mentioned embodiment can be achieved, and when the elastic ring 5 is set on the inner lid 4, the elastic ring 5 is inserted into the insertion holes 18, 18. The elastic ring 5 is fixed by fixing the projecting pieces 11, 11 of
Since the inner cover 4 can be prevented from coming off from the inner cover 4, assembly work can be facilitated.

FIG. 7 shows a third embodiment of this invention, in which a top plate part 26 is provided on the cylindrical part 8 of the inner lid 4, and a male thread of the opening part 2 is provided at an opposing position on the inner circumference of the elastic ring 5. 10 to be engaged with each other, and an opening (in the illustrated example, an insertion hole 28). In addition, a second
As in the embodiment, the inner plug 22 is fitted, and the top plate portion 26 of the cylindrical portion 8 has a protrusion 29 for closing the spout 23 of the center 22 and an annular rib 30 that presses the inner plug 22. It is provided. Also, in a container configured in this manner, the same effects as in the above-described embodiment can be achieved.

"Effects of the Invention" As explained above, the present invention provides the following excellent effects.

By pinching and pressing the pair of pressing parts of the elastic ring with your fingers, you can bend the elastic ring and release the threaded connection between the protruding piece and the male thread provided on the outer periphery of the mouth. The lid can be inserted into and removed from the mouth without interference from screws, and the opening operation of the lid can be easily performed with one hand. Moreover, since the protruding piece extends along the threading direction of the male thread, the protruding piece forms a part of the female thread that is screwed into the male thread, allowing the lid to be rotated without bending the elastic ring. You can easily open it by letting it open.

The elastic ring has a flexible annular part inserted into the outer periphery of the cylindrical part and formed in a concentric cylindrical shape surrounding the cylindrical part, so when the elastic ring is set, the annular part are attached concentrically around the axis of the mouth, and as a result, the protruding pieces protruding from the inner periphery of the annular part are securely screwed together with the male threads on the outer periphery of the mouth, and these screw connections allow the container to be can be reliably sealed. In other words, since the annular part with the protruding piece protruding from the inner periphery has a cylindrical shape centered on the axis of the mouth, the protruding piece that is screwed onto the male thread extends horizontally from the center of the mouth. There is no bias, and for this reason,
It is possible to prevent the screw from coming off (the engagement between the male screw and the protruding piece is released) and maintain the sealed state of the container.

The annular part of the elastic ring is formed into a cylindrical shape large enough to fit within the outer periphery of the cylindrical part, and at opposite positions on the inner periphery, the plate thickness is smaller than the height dimension of the annular part and also fits within the opening. Since a protruding piece with a length dimension of the same size is protruded, a slight elastic deformation of the annular portion will reduce the amount of sliding of the protruding piece necessary to release the engagement between the protruding piece and the male thread. It will be sufficiently secured. Therefore, even if it is repeatedly operated, plastic deformation or elastic fatigue hardly occurs in the elastically deformed portion, and its function is stably exhibited for a long period of time.

Also, if we focus on the state when the engagement between the protruding piece and the male thread is released, the part of the annular part that is 90 degrees circumferentially displaced from the pressing part deforms outward due to the pressing operation by the pressing part. As the protrusions protrude from the inner periphery of the screw, the protrusions that protrude from the inner periphery of the screw are spaced apart from each other. It can be deformed and maintain reliability as a screw over long periods of use.

Furthermore, since the protruding piece is formed to have a plate thickness smaller than the height of the annular portion and a length large enough to fit into the opening, the thickness can be easily adjusted to correspond to the pitch of the male screw. , it is possible to improve applicability to various containers having different thread pitches at the mouth.

Assembling the lid is a simple task of inserting the annular part of the elastic ring into the outer periphery of the cylindrical part of the inner lid, setting the elastic ring on the bottom plate, and placing and gluing the outer lid on top. Since the opening of the outer cover is open at the lower end, it can be inserted without being interfered with by the pressing part of the elastic ring, and no techniques such as force fitting are required when assembling the outer cover, which improves work efficiency. There are also benefits that can be improved.
