Description

[Detailed Description of the Invention] The present invention relates to a container for storing, for example, cosmetics, and more specifically to a container whose lid can be opened and closed by simply pushing down or slightly rotating the lid.

Conventionally, in containers for storing cosmetic liquids such as milky lotions and lotions, a threaded part is provided on the outer periphery of the opening of the container body, and a female threaded part is provided on the inner periphery of the lid.
The lid is opened and closed by screwing and unscrewing using both of these threaded portions. Therefore, such a container has the disadvantage that the lid must be rotated through a considerable angle each time the lid is opened or closed, which is very cumbersome.

The present invention was developed in view of the above circumstances, and its purpose is to provide a container that can be closed by simply pushing down the lid, and which can be opened by slightly rotating the lid. In a container consisting of a container body having a small-diameter mouth at the top and a lid covering the mouth of the container body, the lid is an inner lid having a flange at the bottom of the cylindrical part. A flexible elastic ring is set on the flange of the inner lid so as to surround the cylindrical portion, and the elastic ring is elastically deformed between the inner lid and the inner lid. and an outer lid that is housed with a clearance between them, and openings that open at the upper ends of the side walls are formed at mutually opposing positions in the side walls of the cylindrical part of the inner lid, and openings that open at the upper ends of the side walls are formed at mutually opposing positions, and the inner circumferences of the elastic rings are opposite to each other. A protrusion is provided at a position where the protrusion engages with a protrusion provided on the outer periphery of the mouth of the container body, and this protrusion is inserted into an opening provided in the side wall of the cylindrical portion so as to be slidable in the radial direction of the cylindrical portion. The outer cover is made to protrude into the cylindrical part, and further includes a base plate, a cylindrical part extending downward from the base plate, and a cylindrical part disposed concentrically with the cylindrical part; The size is such that when the outer lid and the inner lid are fitted together, the lower end thereof is butted against the upper end of the cylindrical portion of the inner lid, and the shoulder formed around the mouth of the container body is formed. Provided on the outer periphery of the portion is a stepped portion which is continuous in the circumferential direction and whose distance from the mouth portion varies as the distance from the mouth portion increases in the circumferential direction, and connects the stepped portion and the mouth portion with a tapered surface with the mouth side facing upward; A concave portion that engages with the stepped portion is provided on the lower surface of the brim of the inner lid, so that when the lid is rotated, the lower surface of the lid rides on the tapered surface.

Hereinafter, the present invention will be explained based on each embodiment shown in the drawings.

Figures 1 to 6 show a container according to the present invention, which is composed of a container body 1 for storing cosmetic liquid, and a lid 3 that covers the mouth of the container body 1. When it is folded and closed, it has an approximately rectangular parallelepiped shape. The lid body 3 consists of an inner lid 4, a flexible elastic ring 5, and an outer lid 6 that accommodates these inside, and both the inner lid 4 and the outer lid 6 have some elasticity.

The inner lid 4 has a cylindrical portion 7 and a rectangular outer periphery flange 8 extending radially outward from the lower part of the cylindrical portion 7, and has opposing positions on the side walls of the cylindrical portion 7. Openings 9, 9 that open at the upper end of the side wall are cut out, and a step 10 that continues in the circumferential direction is formed on the outer periphery of the upper surface of the collar 8.
At the outer periphery of the lower surface is a stepped portion 21 of the container body 1, which will be described later.
A recess 11 is formed to engage with.

The elastic ring 5 has an elliptical shape as shown in FIG. 6, and the dimension of its minor diameter is set to be equal to or smaller than the outer diameter of the cylindrical portion 7 of the inner lid 4. Further, protrusions 12 are provided on the inner circumferential surface of the short diameter portion so as to face each other and engage with protrusions 19 provided on the outer periphery of the mouth 2 of the container body 1. The tip of this protruding piece 12 has a horizontal cross section formed in an arc shape to match the convex outer peripheral surface of the mouth portion 2 of the container body 1, and a vertical cross section having a hemispherical shape as shown in FIGS. 4 and 5. is formed. The elastic ring 5 is attached to the cylindrical portion 7 on the collar portion 8 of the inner lid 4.
The projecting piece 12 is slidably inserted into the notch 9 in the radial direction of the cylindrical part 7 so as to surround the cylindrical part 7, and is mounted so as to protrude into the cylindrical part 7.

The outer lid 6 also includes a rectangular base plate 13, a cylindrical part 14 extending downward from the base plate 13, and a cylindrical part 1 having a cross-sectional shape concentrically with the cylindrical part 14.
It consists of 5. And the inner cylindrical part 1
4 are brought into contact with the upper end of the cylindrical part 7, and the lower end step part 15a of the outer cylindrical part 15 is brought into contact with the flange part 8.
By fitting into the stepped portion 10 formed on the outer circumferential portion of the upper surface, the lid body 3 is configured to house the elastic ring 5 therein with an elastically deformable clearance interposed therebetween. Further, on the lower surface of the substrate 13, a protrusion 16 for closing a hole 15 of the container body 1, which will be described later, is provided at the center, and an annular rib 17 is protruded from the protrusion 16. In addition, 18 is a rib, and the outer cylindrical part 15 and the inner cylindrical part 14 are mutually reinforced by this.

The mouth portion 2 of the container body 1 is formed to have a small diameter, and a protrusion 19 is provided on the outer periphery of the mouth portion 2 in an annular shape. As shown in FIGS. 4 and 5, the protrusion 19 has an upper portion inclined so as to gradually descend toward the distal end, and a lower portion thereof inclined so as to gradually rise toward the distal end. Further, a step portion 21 that is continuous in the circumferential direction and has a rectangular shape when viewed from above is provided on the outer circumferential portion of the shoulder portion 20 formed around the mouth portion 2, and this step portion 21 and the lower end of the mouth portion 2 are They are connected by a tapered surface 22 with the mouth portion 2 side facing upward. Further, a circular groove 23 is provided on the upper outer periphery of the mouth portion 2, and a spout 24 is further opened on the upper surface of the mouth portion 2. An inner stopper 26 made of soft synthetic resin having a hole 25 communicating with the spout 24 is provided at the upper part of the spout 2, and an annular protrusion 27 provided on the inner periphery of the lower part is fitted into the annular groove 23. It is attached so as to cover the upper surface of the mouth portion 2. Further, an annular rib 28 is provided on the inner surface of the inner stopper 26, and when the lid body 3 is closed, the rib 28 is pressed by the rib 17 and comes into elastic pressure contact with the upper surface of the spout 2. This makes it possible to prevent liquid from leaking between the inner stopper 26 and the mouth portion 2.

Next, a case will be described in which the lid 3 is opened and closed in the container configured as described above. When closing the lid 3, the inner lid 4 is fitted into the mouth 2 of the container body 1, and the inner lid 4 is arranged so that the outer surface of the lid 3 and the outer surface of the container body 1 overlap each other when viewed from above. , press down the lid 3. Then, elastic ring 5
The protrusion piece 12 receives an outward pressing reaction force from the protrusion 19 by pressing the upper inclined surface of the protrusion 19 with its tip lower circular arc surface, and as a result, as shown in FIG. The elastic ring 5 is appropriately elastically deformed to allow the protruding piece 12 to move outward. As a result, the protrusion 12 climbs over the protrusion 19, and then the protrusion 12
is urged inward by the elasticity of the elastic ring 5 and engages with the lower part of the protrusion 19 as shown in FIG. It engages with the stepped portion 21. For this reason, the lid body 3
is non-rotatably engaged with the container body 1 with the required engagement force.

On the other hand, when opening the lid 3, the lid 3 is rotated slightly to the left or right in the horizontal direction with respect to the container body 1. Then, the recess 11 provided at the lower part of the lid 3 is disengaged from the step 21 of the container body 1, and the lower end of the lid 3 then rides on the tapered surface 22, causing the lid 3 to be further disposed of. It moves upward as it rotates. At the same time, the upper circular arc portion of the tip of the protruding piece 12 presses the lower inclined surface of the protruding rim 19, thereby receiving an outward pressing reaction force from the protruding rim 19, and the elastic ring 5 is appropriately elastically deformed to allow the protruding piece 12 to move outward, and as a result, the protruding piece 1
2 gets over the protrusion 19. In this way, the lid body 3
By slightly rotating the recess 11 and step 2,
1 and the protrusion piece 12 and the protrusion 19 are both released, and the lid body 3 is disengaged from the container body 1.

FIG. 7 shows another embodiment of the present invention. In this embodiment, an elastic ring 31 having a substantially perfect circular cross section is attached to the outer cover 6 and the inner cover 34.
It is housed with an elastically deformable clearance interposed therebetween. In addition, protrusions 32, 3 are provided on the inner surface of the elastic ring 31 at locations facing each other.
2 are respectively attached, and an elastic ring 31
Notches 33, 33 are provided at the lower ends of the protrusions 32, 32, respectively, at positions offset by 90 degrees in the circumferential direction. In addition, the inner lid 34 includes a cylindrical portion 35.
A notch (opening) through which the protruding piece 32 is inserted into the upper part of the
36 is provided, and a protruding guide portion 38 that fits into the notch 33 is provided on the upper surface of the collar portion 37.
is provided. When the elastic ring 31 is stored between the outer cover 6 and the inner cover 34, the notch 3
3 is fitted into the protrusion guide portion 38,
Movement in the direction of connecting both protruding pieces 32, 32 is restricted. However, in this example,
The protruding guide portion 38 restricts the movement of the elastic ring 31 in a predetermined direction, and as a result, the elastic ring 31 can be formed to have a substantially perfect circular cross section, which has the advantage that the elastic ring 31 can be manufactured easily. .

In each of the above embodiments, the recessed portion 11 and the stepped portion 21 have a rectangular shape when viewed from above to match the container, but are not limited to this, and may be triangular or pentagonal. It may also have an elliptical shape.

As explained above, according to the present invention, flexible elastic rings are housed in the lid body with an elastically deformable clearance interposed therebetween, and the openings of the container body are located at mutually opposing positions on the inner periphery of the elastic rings. A protruding piece is provided to engage with a protrusion provided on the outer periphery of the container body, and a step part is provided on the shoulder part of the container body that is continuous in the circumferential direction and whose distance from the mouth part varies in the circumferential direction. and the mouth part are connected by a tapered surface with the mouth side facing upward, and a recessed part is provided at the bottom of the lid body that engages with the stepped part, so the lid body can be closed simply by pushing down, and the lid can be closed in the closed state. The engagement can be released by simply rotating the body slightly, and the protrusions and protrusions undergo extremely little wear and deformation, allowing them to reliably perform their functions over a long period of time. That is, according to the present invention, when the lid body is pushed down in alignment with the mouth part, the protruding piece of the elastic ring crosses over the protrusion and engages with the lower part of the protrusion. Since the recess engages with the stepped portion of the container body, the lid can be non-rotatably attached to the container body with the required engagement force. Since the lower end rides on the tapered surface and moves the lid upward, the engagement between the protrusion and the protrusion can be released and the lid can be easily removed. It can prevent wear and deformation of the pieces and protrusions, and can reliably perform its functions over a long period of time. In addition, as mentioned above, since the elasticity of the elastic ring is used to engage the lid with the container body, the engagement force of the lid with the container body is reduced compared to a method that uses the frictional engagement force between screws. Variations can be reduced, and it is possible to easily manage the attachment of the lid to the container body when manufacturing the container or filling the container with a filler.

Further, according to the present invention, openings that open at the upper ends of the side walls are formed at mutually opposing positions in the side walls of the cylindrical portion of the inner lid, and at mutually opposing positions on the inner periphery of the elastic ring, openings are formed on the outer periphery of the opening of the container body. A protruding piece is provided to engage with the protruding strip provided in the cylindrical part, and this protruding piece is slidably inserted into the opening provided in the side wall of the cylindrical part in the radial direction of the cylindrical part so as to protrude into the cylindrical part. the outer lid,
Consisting of a substrate, a cylindrical portion extending downward from the substrate, and a cylindrical portion disposed concentrically with the cylindrical portion,
In addition, since the size of the cylindrical portion is such that when the outer cover and the inner cover are fitted, the lower end thereof is butted against the upper end of the cylindrical portion of the inner cover, the protrusion of the elastic ring is inserted into the inner cover. The lid body can be easily assembled by inserting the elastic ring into the opening of the cylindrical portion of the lid, setting the elastic ring on the collar portion, and then placing the outer lid over the elastic ring. In other words, when the elastic ring is set on the brim of the inner cover and the outer cover is placed on it, the cylindrical part of the outer cover abuts against the upper end of the cylindrical part, and the projecting pieces of the elastic ring are prevented from falling out by the cylindrical part. This allows the elastic ring to be easily assembled into the lid body.

Particularly, according to the present invention, the lid body can be assembled by simply inserting and fixing the three members (inner lid, elastic ring, and outer lid), so there is no special need for assembly work. This method has the advantage that it does not require additional technology or equipment and can improve workability.

Furthermore, according to the present invention, the protrusions are provided at opposing positions on the inner periphery of the elastic ring to engage with the protrusions provided on the outer periphery of the mouth of the container body. Since the elastic ring is engaged through the protruding piece, the elastic ring's wall thickness, width (vertical height dimension), ring diameter,
In addition, the shapes of the protrusions are no longer dependent on correlation, and therefore the degree of freedom in design is greatly improved. That is, for example, if the thickness and width of the elastic ring,
Even if the design of the ring diameter etc. is changed to match the elastic force required for the elastic ring or the shape of the lid body, the shape of the protrusion itself will not be affected in any way.
It is sufficient to equip it with a protrusion as shown.
In addition, since the protrusion is provided in this way, the tip of the protrusion can be made into an arc shape in plan or semispherical in longitudinal section to match the shape of the mouth of the container body, so that it can be easily engaged and disengaged from the protrusion. It is also possible to design the system so that it can be carried out smoothly and reliably without any restrictions.

In addition, since the tapered surface that slides against the bottom surface of the lid and lifts it up is formed in the wide shoulder area around the mouth of the container body, the taper has a large height difference even with a gentle inclination angle. surface can be formed, so just by slightly rotating the lid,
Unique features include the ability to raise the lid sufficiently to release the engagement between the protrusion and the protruding piece, and the force to raise the lid increases, making the operation to open the lid smoother. You can also get the effect of
