Description

[Detailed Description of the Invention] The present invention relates to an improvement of a container in which an inner stopper is applied to the mouth of the container and then an outer lid is covered.

Conventional containers that have an inner stopper and an outer lid are
As shown in the figure, the opening 11 of the container 10 is compressed by both the downward outer cylinder 21 and the downward inner cylinder 22 of the inner stopper 20, thereby preventing leakage of stored contents and separation of the inner stopper. did.

Further, the outer lid 30 has a skirt portion 32 extending downward from the outer edge of the top plate portion 31, and a threaded portion 35 having a female screw portion 34 and an abutment portion 33. inner stopper 2
0, it tightly screws together with the male thread 26 of the inner plug 20 to prevent the outer lid from falling off.

The close contact of the contact portion 33 prevents leakage of stored items.

By the way, when the stored item is oil, it is inevitable that a thin film of oil will adhere to the inner surface 12 of the container mouth 11 not only during pouring but also after pouring.

Then, when closing the outer cover 30, the screws are not only tightened more than necessary, but also the screws between the female screw 34 and the male screw 26 are tight, and if the abutment part 33 is under strong pressure, the outer cover 30 and the inner plug 20 becomes stronger than the frictional bonding force between the container opening 11 to which a thin film of oil has adhered and the inner stopper 20, so when the outer cover is rotated to open the outer cover, the outer cover and In many cases, the inner stopper rotates together with the outer lid without being screwed back into place with the inner stopper.

The container according to the present invention eliminates these conventional drawbacks as described below.

As shown in FIG. 2 and FIGS. 3 and 4, the enlarged portion 13 on the outside of the container mouth 11 is provided with ratchet teeth 14 that rotate clockwise in the circumferential direction.

On the other hand, the inner stopper 20 is molded from a soft synthetic resin material, and as shown in FIG.
The diameter is slightly smaller than the diameter of the ratchet tooth tip 14 provided on the enlarged portion 13 of the tooth.

When the inner stopper 20 having such a structure is pushed down from above without rotating against the container mouth 11, the enlarged portion 24 of the downwardly directed outer cylinder is pressed down because the inner stopper 20 is molded from a soft synthetic resin material.
expands and passes over the ratchet teeth 14, and the inner stopper 20 is fitted into the container opening 11 as shown in FIG.

At this time, the diameter of the downward outer cylindrical inner surface 23 of the inner stopper 20 is the same as that of the ratchet tooth tip 16 provided in the enlarged part 13 of the container mouth 11.
As shown in FIG. Rotation is reliably prevented.

As mentioned above, ratchet teeth are provided on the enlarged portion 13 on the outside of the container mouth to prevent counterclockwise rotation, which is the general opening direction of the outer lid 30, so that when closing the outer lid 30, there is no need to inadvertently tighten the lid. Even when the outer lid 30 and the inner stopper 20 are tightly screwed together for the first time, the right-handed ratchet teeth 14 provided on the enlarged portion 13 on the outside of the container mouth are not able to fit inside the inner stopper molded from a soft synthetic resin material. Since the stopper 20 bites into the inner surface 23 of the downwardly facing outer tube 21, when the outer cover is rotated counterclockwise in the opening direction when trying to open the seal, the inner stopper 20 is inserted into the container opening by the ratchet teeth 14. Therefore, the outer cover 30 begins to rotate in the opening direction relative to the inner stopper 20, and can be easily removed.

Note that the inner stopper 20 is not designed to be screwed into the container opening 11, but is fitted into the container opening 11 in the axial direction of the container, so as shown in FIG. The inner stopper 20 can be easily inserted into the container opening 11 by providing an inclined part 15 on the upper part of the container, or by providing an inclined part 25 at the lower part of the inner stopper, or both.

As mentioned above, the container according to the present invention is a container in which the inner stopper 20 is fitted into the container opening 11 and the outer lid 30 is further screwed onto the inner stopper 20. Ratchet teeth 14 are provided on the outer expanded portion 13 of the mouth portion 11 to prevent rotation of the outer lid in the opening direction, and the inner stopper 20
is made of a soft synthetic or cast wood material, and the diameter of the inner surface 23 of the lower outer cylinder 21 of the inner plug is slightly smaller than the diameter of the tip 16 of the ratchet teeth 14, so that when the outer lid 30 is opened, This container is equipped with an inner stopper characterized by a structure in which the ratchet teeth 14 bite into the downwardly directed outer cylinder 21 of the inner stopper 20 to prevent the inner stopper 20 from rotating in the opening direction.

As described above, the container equipped with the inner stopper according to the present invention is provided with ratchet teeth 14 on the outer expanded portion 13 of the container mouth to prevent the inner stopper from accidentally rotating and falling off when the outer lid is opened. Moreover, since the ratchet teeth 14 are provided at the mouth of the container and the inner plug 20 is molded from soft synthetic resin, the ratchet teeth 14 bite into the inner surface 23 of the downwardly directed outer cylinder 21 of the inner plug. 20 is prevented from rotating, and there is no need to form ratchet teeth on the inner plug 20, which facilitates the manufacture of the inner plug 20 and has the advantage that it can be mass-produced at low cost.
