Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cap structure for a container with a cap, and particularly to a structure in which an independent cap is removably fitted to the container.

Conventionally, containers with caps of this type of structure have two types: one in which the cap is screwed onto the open cylindrical part of the container, and the other in which the cap engages elastically and reversibly between a locking protrusion on the cap and a locking protrusion on the container. In general, the cap is fitted onto the container. The latter type of fitting structure is easier to handle than the former type of screw type structure because the cap can be attached and removed with a single touch. but,
It is relatively troublesome to set the fitting strength between the cap and the container, which causes the following problems.

If the strength of the fit between the cap and the container is increased, the cap will not come off easily, which is preferable in terms of sealing performance, but the ease of removal will be extremely poor. On the other hand, if the fitting strength is reduced, the cap will be easier to remove, but at the same time the cap will be more likely to come off by mistake, which is not preferable.

This invention was made in view of the above-mentioned conventional problems, and its purpose is to provide an easy-to-use product that allows the cap to be easily removed even if the combined strength of the cap and container is sufficiently increased. The main purpose is to provide a container with 1-up.

In order to achieve the above object, the present invention includes a bushing piece that can be slid by external operation fitted into the cap, and at least one of the abutment surfaces between the bushing piece and the container is formed into an inclined surface. and when the bushing piece is pressed inward with the cap fitted to the container, the pushing IJ force acts on the inclined surface to generate a force component in the direction of detaching the cap. It is characterized by what it did.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

1 and 2 show a container with a cap according to an embodiment of the present invention. In particular, FIG. 2 is a composite of the state in which the cap is completely closed (A) and the operating state (B) when the knob is removed.

In this embodiment, the main body portion of the container 10 has a rectangular parallelepiped shape,
A pedestal portion 11 is formed at the center of the upper surface portion and is one step higher than the periphery, and an open cylindrical portion 12 is formed protruding from the center of the pedestal portion 11.

The outer periphery of the distal end of the open cylindrical portion 12 is formed into a tapered shape, and an annular locking protrusion 13 is integrally formed continuous with this tapered surface. Further, an inclined surface 14 is formed on the shoulder portion of the short side of the platform portion 11 .

The cap 20 is a plastic molded product, and has a ceiling surface 21 having almost the same shape as the top surface of the container 10, and a rectangular cylindrical outer wall 22 hanging around the ceiling surface 21.
It has the appearance of a continuous rectangular parallelepiped.

On the inside (lower surface side) of the ceiling surface 21 of the cap 20, a cylindrical stopper 23 is formed protruding from the center. This cylindrical stopper 23 penetrates into the center hole of the open cylindrical portion 12 of the container 10 and closes it. Further, a fitting cylinder part 24 that is one size larger than the outer diameter of the open cylinder part 12 is formed around the cylindrical stopper 23, and this is the main part of the fitting structure between the container 10 and the cap 20. That is, an annular locking projection 25 is integrally formed on the inner circumferential surface of the fitting cylinder 24, and an elastic and reversible connection between this locking projection 25 and the locking projection 13 on the container 10 side is achieved. Upon engagement, the cap 20 is removably fitted to the container 10.

Further, on the lower surface side of the ceiling surface 21, an intermediate wall 26 is formed in a square cylindrical shape at a constant interval from the outer wall 22, and further, an intermediate wall 26 is formed at a constant interval inside the short side of the intermediate wall 26.
7 is formed. On the short side of the key-up 20, the height of the intermediate wall 26 is approximately the same as the outer wall 22, and the height of the intermediate wall 26 is approximately the same as that of the outer wall 22.
7 is shorter than these.

Bushing pieces 30, 30 are attached to opposite short sides of the cap 20, respectively. Bush Piece 30
This is a T-shaped combination of a plate-shaped operation button part 31 and a hollow plate-shaped action piece part 32. A notch 29 having substantially the same shape as the operation button part 31 is formed in the outer wall 22 on the short side, and a through hole 28 into which the operating piece part 32 is inserted is formed in the intermediate wall 26 on the short side. . The operating piece 32 of the bushing piece 30 is arranged horizontally, and is slidable in the horizontal direction (perpendicular to the direction of attachment and detachment of the cap 20) using the through hole 28 as a guide hole. here,
The height of the lower end surface of the aforementioned short intermediate wall 27 is substantially the same as the upper side of the through hole 28, and the upper surface of the working piece portion 32 of the bushing piece 30 comes into sliding contact with the lower end surface of the intermediate wall 27.

Further, the bottom surface side of the tip of the action piece portion 32 of the bushing piece 30 has an inclined surface 33 having the same angle as the above-mentioned inclined surface 14 of the container 10.
These two slopes 14 and 33 are in contact with each other.

Note that a step portion 34 is formed on the lower surface side of the action piece portion 32, and the bushing piece 30 is inserted through the through hole 28 of the intermediate wall 26.
is designed to prevent it from falling off.

In the state shown in FIG. 2(A), the cap 20 is completely fitted into the container 10. That is, the locking protrusion 25 on the cap 20 side passes over the locking protrusion 13 on the container 10 side, and the cap 20 is positioned at the correct closed position with respect to the container 10. In this state, the bushing piece 30 is attached to the inclined surface 1
4 and 33 push outward in the horizontal direction, and the outer surface of the operation button portion 31 slightly protrudes from the outer wall 22.

To remove the cap 20 from the above state, please refer to Figure 2 (
As shown in B), the bushing piece 30 of the cap 20
Push in like the arrow. This pressing force pushes the bushing piece 30 inward in the horizontal direction and causes it to slide. At this time, the inclined surface 14 of the container 10 is an uphill slope with respect to the sliding direction of the bushing piece 30, so that the reaction force that the bushing piece 30 receives from the container 10 is 1 lJ.
The direction is perpendicular to the direction 14, and includes an upward component force. The upward force acting on the bushing piece 30 is transmitted to the intermediate walls 26 and 27 and acts to push the entire cap 20 upward. This force pushes the cap 20 upward, the locking protrusion 25 elastically climbs over the locking protrusion 13, and the cap 20
It deviates from 0.

Here, the wedge effect caused by the contact between the inclined surfaces 14 and 33 generates a large force that pushes the cap 20 upward, so that the opening cylindrical portion 12 of the container 10 and the fitting cylindrical portion 24 of the cap 20 fit together. Even if the strength is sufficiently increased, the cap 20 can be easily removed by pressing the two bushing pieces 30 provided facing each other so as to sandwich them.

Note that it is not necessary to make both the contact surfaces of the bushing piece 30 and the container 10 sloped surfaces, and only the bushing piece 30 side is sloped as shown in FIG. 3 (A>).

33 may be formed, or even if the inclined surface 14 is formed only on the container 10 side as shown in FIG. 3(B), the same effect as in the embodiment described above can be obtained.

Moreover, the number of the bushing pieces 30 may be only one.

In that case, the force applied to the cap by pushing the bushing piece is localized, and the cap will come off the container in a tilted manner, but the purpose of facilitating the removal of the cap is fully achieved.

In the above embodiment, the operating end of the bushing piece 30 is exposed to the outside, but in order to improve the external appearance, the fourth
As shown in the figure, the entire cap 20 can be covered with an outer cap 20a made of soft synthetic resin. In this case, the outer cap 20a may be made entirely of soft synthetic resin, or the lower half where the bushing piece 30 is located, as shown in FIG. It is okay to do so.

Furthermore, it goes without saying that the opening cylindrical portion 12 of the container 10 is not limited to a relatively small diameter as shown in the figure.

When the opening cylinder part 12 has a large diameter and the fitting cylinder part 24 also has a large diameter, the bushing piece 30 may directly contact the fitting cylinder part 24 and push it up with the above-mentioned force. .

In addition, the push-in direction of the bushing piece 30 is also the same as that of the cap 2.
The cap 2 is not limited to being pushed in the horizontal direction that is completely perpendicular to the direction in which the cap 2 is removed.
It is possible to generate a component force that pushes 0 upward. OF5
It is.

As explained in detail above, if the present invention has J characteristics, even if the strength of the fitting between the cap and the container is increased and the reliability of the IM plug state is sufficiently increased, the 4:1/removal of the knob is It is very easy to operate and extremely convenient to use.
