Description

[Detailed description of the invention] The purpose of this application is to cover the container body with the cap body and turn the screw to tighten it, so that the cap can be securely stopped at the front position and a strong sealing performance can be obtained. The purpose of the present invention is to provide an engagement structure between a container opening and a cap.

Another object of the present application is to provide an engagement structure between the container opening and the cap that prevents the cap from loosening because two protrusions provided on one axis of the container body serve to prevent the cap from returning. It is on offer.

Another object of the present application is to provide a structure for engaging a container opening and a cap, which allows the cap body to be removed from the container body with a light force.

Now, to explain the embodiment in order to achieve the above object, a large-diameter fitting opening 2 and a small-diameter screw opening 3 are connected to the upper part of the container body 1, and the large-diameter fitting opening 2 is aligned on one axis of the large-diameter fitting opening 2. Parallel to the inner side of the side walls 8 at both longitudinal ends of the cap main body 7, which has protrusions 4 with rounded tips facing each other, and a threaded tube 6 with a female screw 5 provided inside in the center. A wall plate 9 is provided for each wall plate 9, and a vertical groove 10 is carved in the center of the wall plate 9 from the bottom to the middle. One side of the wall plate 9 is fixed to the arc-shaped side wall 11, and the other side is vertically grooved from the bottom. A groove 12 having the same height as the groove 10 is carved, but the groove 12 is provided at a diagonal position with respect to the two wall plates 9 to form the cap body 7, and the container body formed in this way is 1 and the cap body 7 are combined to form a whole.

Reference numeral 13 denotes a rib connecting the side wall 8 and the wall plate 9 at the upper part of the vertical groove 10, and is provided for reinforcement.
14 is a cylinder that seals the opening of the middle cap 15 and is provided at the center of the threaded tube 6.

Furthermore, although it is ideal that the protrusion 4 is about 1/3 of the height of the fitting opening 2, it is not limited to this height.

In the present application, when fitting the cap body 7 to the container body 1 based on the above-mentioned structure, when the threaded tube 6 is fitted into the threaded opening 3 and screwed together, the protrusion 4 becomes free of the wall plate 9. As shown in FIG. 5, when the cap body 7 hits the wall plate 9' that is attached to the wall plate 9', it is pushed rearward and spread out, and when the cap body 7 is further rotated, the protrusion 4 fits into the vertical groove 10 and stops. At that time, the free wall plate 9' returns to its original position. When removing the cap body 7 from the container body 1, it is sufficient to rotate it in the opposite direction, but by making the protrusion 4 and the end of the free wall plate 9' fit together, the cap body 7 can be rotated easily. When the projection 4 is removed from the vertical groove 10, it is pressed by the elasticity of the free wall plate 9', so that the rotation of the cap body 7 becomes easier.

As described above, the present application connects a large diameter fitting opening 2 and a small diameter screwing opening 3 to the upper part of a container body 1, and has a protrusion whose tip is rounded on one axis of the large diameter fitting opening 2. 4 facing each other, and a wall plate for each one parallel to the inside of the side walls 8 at both longitudinal ends of the cap main body 7, which has a threaded tube 6 with a female screw 5 provided inside in the center. 9, and a vertical groove 10 is carved in the center of the wall board 9 from the bottom to the middle, one side of the wall board 9 is fixed to the arc-shaped side wall 11, and the other side is carved with the vertical groove 10 from the bottom.
The grooves 12 are carved at the same height as the cap body 7, but the grooves 12 are diagonally arranged with respect to the two wall plates 9 to form the cap body 7. Since it is combined with the cap body 7, it is possible to achieve the desired purpose.

Claims (1)

[Scope of utility model registration request] A large-diameter fitting opening 2 and a small-diameter screwing opening 3 are connected to the upper part of the container body 1, and a protrusion 4 with a rounded tip is formed facing each other on one axis of the large-diameter fitting opening 2. Separately from this, wall plates 9 for each one parallel to the inside of the side walls 8 at both ends in the longitudinal direction of the cap main body 7 have a threaded tube 6 with a female screw 5 provided inside in the center.
A vertical groove 10 is provided in the center of the wall board 9 from the bottom to the middle.
One side of the wall plate 9 is fixed to the arc-shaped side wall 11, and the other side is carved with a groove 12 at the same height as the vertical groove 10 from the bottom.
The grooves 12 are formed diagonally on the two wall plates 9 to form the cap body 7, and the container body 1 and the cap body 7 thus formed are combined. An engagement structure between the container mouth and the cap.
