Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a container for storing solid confectionery foods such as tablets and candies.

[Conventional technology]

Conventionally, in the case of a container in which tablet medicines or solid foods are taken out one by one, usually, an inner lid provided with a taking-out hole for one piece fits the container body filled with the product, etc. In many cases, the inner lid is covered with an outer lid, and the take-out hole is sealed to protect the product.

In the case of such an inner lid method, in order to prevent the inner lid from being removed from the container, most of them are, for example, annular undercut fittings that are mating mating partners with each other at the peripheral ends of the inner lid side and the container side. An uneven fitting portion is formed on the rib or a part of the circumference, and the fitting of both fitting portions prevents the inner lid from coming off.

For example, as such a container, Japanese Utility Model Publication 58-34028
There is one disclosed in the publication. In this container,
A folded-back portion protruding inward is provided at the open end of the container body. On the other hand, three arc-shaped ribs protrude downward from the peripheral edge of the back surface of the inner lid, and the protrusions that protrude outward are provided at the tips of the ribs.

In this container, the rib of the inner lid is pressed against the open end, the rib is elastically bent inward and passed through the folded portion, and after this passage, the rib elastically returns and spreads outward, so that the protruding portion becomes the folded portion. The folded back portion is sandwiched between the peripheral edge portion of the inner lid and the protruding portion of the rib tip to fix the inner lid.

[Problems to be solved by the invention]

In the container, in order to prevent the inner lid from rattling in the vertical direction and the radial direction after being attached, the folded-back portion of the container main body is applied to three places on the outer peripheral back surface of the inner lid, the rib outer peripheral surface and the upper surface of the protruding portion. I am in contact.

In such a structure, loose fitting between the folded-back portion of the container body and the inner lid causes rattling, and tight fit makes poor fit,
The inner lid may come off easily.

Therefore, extremely high dimensional accuracy is required when manufacturing the container body and the inner lid, and it is difficult to control the manufacturing thereof.

The object of the present invention is made in view of the above conventional problems, and an object thereof is to provide a solid container in which the dimensional accuracy of the container body and the inner lid can be made relatively low and the manufacturing control is easy.

[Means for solving problems]

In order to achieve this object, the solid container according to the present invention has the following structure.

That is, the solid container of the present invention is a solid container in which the flat inner lid 20 is fitted in the opening of the container body 10, and the opening of the container body 10 is formed along the upper peripheral edge thereof. A locking rib ring 12 bent in a protruding shape is provided inside.

In the outer peripheral portion of the inner lid 20, the locking rib ring 12 is accommodated with a gap in the radial direction and the vertical direction, and a substantially annular locking recess 25 that can be locked in the locking rib ring 12, Elastic pressing pieces 24 are provided at three or more locations at equal intervals in the circumferential direction.

The elastic pressing piece 24 has a bent portion 24a at the lower part, and a friction fitting portion 24b that is folded outward and upward is extended from the bent portion 24a.

In a state where the inner lid 20 is fitted in the opening of the container body 10, the outer surface of the friction fitting portion 24b that is overlapped is pressed against the locking rib ring 12 of the container body 10 from the inside. .

[Action]

When attaching the inner lid 20 to the container body 10, the inner lid 20 is pushed through the opening of the container body 10 with the friction fitting portion 24 of the inner lid 20 being folded and folded upward, and the engaging recess of the inner lid 20 is inserted. The locking rib ring 12 of the container body 10 is housed in the container 25. Then, the outer surface of the friction fitting portion 24b of the elastic pressing piece 24 is pressed against the locking rib ring 12 from the inside.

Then, the inner lid 20 is pressed in the center direction by the plurality of friction fitting portions 24b, which prevents the inner lid 20 from rattling in the radial direction. Also, the friction fitting 24
A frictional force is generated between b and the locking rib ring 12, and this frictional force prevents the inner lid 20 from rattling in the vertical direction. Therefore, even if there is a gap between the locking rib ring 12 of the container body 10 and the locking recess 25 of the inner lid 20, the inner lid 20 can be attached without rattling.

After the inner lid 20 is fitted, the locking rib ring 12 is locked in the locking recess 25, so that the inner lid 20 does not fall off from the container body 10.

〔Example〕

An embodiment of the solid container according to the present invention will be described below with reference to the drawings.

1 to 3, the container body 10 is, for example, made of metal and has a cylindrical shape having a relatively shallow bottom with respect to the inner diameter of the container.
The upper peripheral edge of the side wall 11 that is an opening is formed as a locking rib ring 12 that is bent inward over the entire circumference. Container body
10 is fitted into a locking rib ring 12 at the upper end and is closed by a circular plate-shaped synthetic resin inner lid 20.

As shown in FIG. 3, the inner lid 20 is provided with a take-out hole 21 having a size enough to take out one product (not shown) in a part of a circular plane. Further, a pair of upper and lower locking projections 22, 23 are formed in an annular shape on the outer peripheral surface of the inner lid 20,
An engaging recess 25 having a U-shaped cross section is formed in an annular shape between the engaging projections 22 and 23. Four elastic pressing pieces 24 are integrally formed on the outer peripheral portion of the inner lid 20 at equal intervals in the circumferential direction so as to divide the locking projections 22 and 23 and the locking recess 25.

That is, the elastic pressing piece 24 is connected to the inner lid 20 side through a bent portion 24a whose lower side is thin-walled, and a friction fitting portion 24b which is raised from the bent portion 24a is provided. The friction fitting portion 24b is erected from the bent portion 24a so as to be folded outward. The front end of the friction fitting portion 24b is a brim portion 24c that is bent substantially at a right angle, and the tip end surface of the brim portion 24c is flush with the outer peripheral surface of the upper locking projection 22 after the start-up. Has become.

On the other hand, an outer lid 30 that covers the inner lid 20 from the outside is fitted and attached to the container body 10, and the take-out hole 21 of the inner lid 20 is closed from above,
The entire container body 10 is sealed.

Next, the operation of this embodiment will be described.

When the inner lid 20 is attached to the container body 10, the friction fitting portions 24b of the elastic pressing piece 24 of the inner lid 20 are folded up and folded up via the bent portions 24a to stand up, and 22 and 23 are dropped into the opening of the container body 10, and the locking rib ring 12 of the container body 10 is housed in the locking recess 25. In addition,
The locking recess 25 is dimensioned so that a gap is formed between the locking rib ring 12 and the locking rib ring 12 in the radial direction and the vertical direction. In addition, the locking rib ring 12 is fixed to the locking recess 25.
When accommodated inside, the friction fit portion 24 that has been raised actually bulges outward from the bent portion 24a in a curved shape, and due to this minute bulge dimension, the locking rib ring 12 on the container body 10 side is Press from the inside. As a result, the inner lid 20 is pressed toward the center by the plurality of elastic pressing pieces 24, which prevents the inner lid 20 from rattling in the radial direction. Further, the friction fitting portions 24b of the plurality of elastic pressing pieces 24 are
A frictional force is generated between the locking rib ring 12 and the locking rib ring 12, and this frictional force prevents the inner lid 20 from rattling in the vertical direction. Therefore,
Even if there is a gap between the locking rib ring 12 of the container body 10 and the locking recess 25 of the inner lid 20, the inner lid 20 can be attached without rattling.

After this, push the inner lid 20 further downward to
The lower surface of the is contacted with the upper surface of the locking rib ring 12. Elastic pressing piece 24
The collar portion 24c is flush with the outer peripheral surface of the upper locking projection 22.

After the inner lid 20 is fitted, the lower locking projections 23 are hooked on the locking rib ring 12 to prevent the inner lid 20 from coming out upward.

Further, by dropping all of the plurality of elastic pressing pieces 24 at equal intervals simultaneously or sequentially into the locking rib ring 12 of the container body 10 from the inside, the entire inner lid 20 is aligned with the upper peripheral edge of the container body 10. So that it fits quickly and securely.

In addition, the locking recess 25 of the inner lid 20 and the locking rib ring 12 of the container body 10
Since there is a gap between the
It is possible to reduce the dimensional accuracy of 12 and the locking recess 25, and manufacturing management is easy.

[Effects of the Invention] As described above, the solid container according to the present invention has an inner lid.
A plurality of elastic pressing pieces 24 are provided on the outer peripheral portion of the container 20, and the friction fitting portion 24b of the elastic pressing piece 24 is engaged with the locking rib ring 12 of the container body 10 with the inner lid 20 fitted in the opening of the container body 10. Since it is made to press and contact from the inside, there is an effect that the inner lid 20 can be attached without rattling even if there is a gap between the locking rib ring 12 and the locking recess 25.

Therefore, it is possible to reduce the dimensional accuracy of the locking rib ring 12 and the locking recess 25, which has the effect of facilitating manufacturing control.
