Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a container in which a lid is screwed onto a container body to be fitted, and more specifically, the lid is always loosened at a predetermined position without being loosened. The present invention relates to a container that can be screwed.

[Conventional technology]

A container in which a lid is screwed onto a container body to be fitted is conventionally
It is widely used as a container for storing various cosmetics.In such a container, the lid can be easily opened and closed, and after closing, the lid does not relax and leakage of contents occurs. What is not desired is desired.

For this reason, various containers have been devised in which the lid can be easily opened and closed and the lid can be closed at a predetermined position without being loosened. For example, in the screwing direction of the bottle lid on the outer peripheral surface of the bottle neck. A protruding protrusion is provided at the same height as the screw thread end, and the stopper lid is separated from this stopper protrusion in the return direction by a protrusion that is slightly lower than the stopper protrusion and loosely reversed in the screwing direction. In the return direction, it has been proposed that the protrusions have a sharp angle. (Jitsuko Sho 52-56293) [Problems to be solved by the invention] However, in this type of container, the stopper projection and the detent projection of the bottle lid are integrally formed on the outer peripheral surface of the bottle neck with the same material as the bottle. And the bosses protruding from the inner peripheral surface of the bottle lid are engaged between these projections to lock the lid at a predetermined position. Due to the friction when repeatedly riding over the detent protrusion, the detent protrusion is apt to wear, and the detent protrusion will wear out after long-term use.
There is a drawback that the lid cannot be screwed at a predetermined position without being loosened.

[Means for Solving the Problems]

The present invention has been made as a result of various investigations in view of the present situation, and includes a stop protrusion protruding from the upper end of the outer peripheral wall of the container mouth and the outer periphery of the container mouth of the inner stopper engaged with the upper end opening of the container mouth. With a reversing prevention projection that is provided on the lower end of the outer peripheral wall that is rockable by providing a space between the lid and the surface, the locking projection that is provided on the inner peripheral wall of the lid is locked, Can be easily opened and closed without abrasion of the return prevention projection of the inner plug, and even if it is used for a long period of time, the lid can be screwed on at a predetermined position without being loosened.

〔Example〕

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

In the figure, reference numeral 1 is a container body, and a container port 2 is provided upright at the upper end of the central portion.

A thread 3 is formed on the outer peripheral wall of the container port 2, and a stop projection 4 is provided on the upper end of the outer wall above the thread 3. Further, a flange portion 6 is provided so as to protrude from the outer peripheral upper edge of the opening end portion 5 of the container mouth 2.

The engaging projection 9 provided inside the inner plug outer peripheral wall 8 that holds the opening end 5 of the container mouth 2 with the inner stopper 7 is engaged with the flange portion 6 of the opening end 5, and Groove 1 recessed in the outer wall of the wall 8
0, the projection 4 for stopping provided on the upper end of the outer peripheral wall of the container port 2
The rear part is fitted and fixed to the open end 5. 1
Reference numeral 1 denotes a backflow preventing projection that is provided on the lower end of the outer peripheral wall 8 of the inner plug, and is adjacent to the stop projection 4 that is provided on the outer peripheral wall of the upper end of the container port 2 at a predetermined interval. Further, between the inner peripheral surface of the lower end portion of the outer peripheral wall 8 of the inner plug and the outer peripheral surface of the opening end portion 5, the outer peripheral wall 8 of the inner plug is provided.
A void 12 is formed in accordance with the engaging projection 9 provided inside. Reference numeral 13 denotes an outlet provided in the central portion of the inner plug 7 for taking out the liquid contents contained in the container little by little.

Reference numeral 14 denotes a lid body fitted over the inner plug 7 into the container mouth 2, and a screw 15 is screwed on the lower portion of the inner peripheral wall to be screwed to the screw 3 of the container mouth 2.
Further, it is engaged and locked between a stop projection 4 projecting from the upper end of the outer peripheral wall of the container mouth 2 on the upper part of the inner peripheral wall, and a reversion preventing projection 11 projecting from the lower end of the outer peripheral wall of the inner plug 7. Locking protrusion 1
6 is projected.

Then, when the lid body 14 is fitted onto the container mouth 2 and the screw 15 formed on the lower inner peripheral surface of the lid body 14 is screwed into the thread 3 on the outer peripheral surface of the container mouth 2 to rotate, The locking projection 16 protruding from the upper portion of the inner peripheral wall of the lid body 14 first comes into contact with the reversion preventing projection 11 protruding from the lower end portion of the inner plug outer peripheral wall 8, and when the lid body 14 is further rotated, the locking projection 16 Is a projection 4 for locking which is provided on the upper end of the outer peripheral wall of the container mouth 2 after overcoming the projection 11 for prevention of reversion.
And is engaged and locked between the stop projection 4 and the reverse return prevention projection 11. Here, when the locking projection 16 gets over the backflow prevention projection 11, the inner plug outer peripheral wall 8
Since a gap 12 is formed between the inner peripheral surface of the lower end portion and the outer peripheral surface of the opening end portion 5 in accordance with the engaging projection 9 provided in the outer peripheral wall 8 of the inner plug, the reversion preventing protrusion 11 is rearward. Gap 12
It bends inward and oscillates, and returns to its original position after overcoming the return prevention protrusion 11. Therefore, even if the lid body 14 is rotated and the locking projection 16 repeatedly rides over the reversion prevention projection 11 and is locked with the stop projection 4, the reversion prevention projection 11 moves backward at each time. It flexes and swings in the gap 12,
Since the friction with the anti-return protrusion 11 is alleviated, the anti-return protrusion 11 is not worn and the lid 14 can be screwed on at a predetermined position without loosening even if it is used for a long period of time.

As described above, since the inner plug outer peripheral wall 8 having the reversion preventing projection 11 formed has a gap 12 at the rear side,
Even if the inner plug 7 integrally formed with the detent protrusion 11 made of the same material as the above, it flexes and swings in the rear gap 12, but flexes and swings in the rear gap 12. The easier it is, the less the detent projection 11 is worn. Therefore, it is preferable that the inner plug 7 integrally formed with the detent projection 11 is made of a material softer than the container body 1. In addition, the inner stopper 7 integrally formed with the detent projection 11
If it is made of a rubbery soft material, the detent protrusion 11 itself is compressed by the elastic force of the detent protrusion 11 itself, even if the gap 12 is not formed behind the inner plug outer peripheral wall 8. Therefore, the friction when the locking projection 16 repeatedly rides over the backflow prevention projection 11 can be alleviated, and therefore the gap 12 does not necessarily have to be formed behind the inner plug outer peripheral wall 8. However, as the gap 12 is formed, the detent projection 11 is less likely to be worn. Therefore, it is more preferable to provide the gap 12 and form the inner plug 7 with a rubbery soft material.

As described above, in the container of the present invention, the stopper projection is provided on the upper end portion of the outer peripheral wall formed with the thread of the container opening erected on the container body, and the inner stopper is provided at the upper opening of the container opening. Engage,
A space is provided between the lower portion of the outer peripheral wall of the inner stopper and the outer peripheral surface of the container mouth, and a protrusion for preventing reversion is provided at the lower end portion of the outer peripheral wall of the inner stopper so that the stopper protrusion and the predetermined stopper at the upper end portion of the outer peripheral wall of the container mouth are provided. Adjacent to each other at an interval, a screw thread is provided inside the outer wall of the container opening and screwed inside the container opening. The locking projection is provided between the reverse projection of the container and the return prevention projection, and the locking projection locks the lid at a predetermined position of the container body. The friction with the anti-return projection is alleviated, the detent projection is not worn, and the lid can be screwed on at a predetermined position without loosening even if it is used for a long period of time. Further, since the lid is always screwed at a predetermined position without being loosened, the contents do not leak even if the container is tumbled, and the lid can be easily opened and closed.
