By the way, in this kind of container with a cap, as in Patent Document 1, it is common to use a cap having a double structure in which an outer lid and an inner lid are combined. That is, since the cap becomes large due to the double structure, even if an attempt is made to replace the conventionally used cap with a cap having a child resistance function, the previous appearance image will be significantly changed. In addition, if the outer lid and inner wall are made smaller to bring them closer to the size of the cap that was used in the past, the mouth of the container needs to be narrowed, and a special container must be used, which is a point of versatility. There is a problem with.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a container with a cap capable of having a child resistance function without increasing the size of the cap.

The present invention is a capped container including a container having a mouth portion with an open upper portion and a cap attached to the mouth portion.
The container has a threaded portion provided on the outer peripheral surface of the mouth portion, an inward protrusion provided on the inner peripheral surface of the mouth portion, and a space between the inward protrusion on the inner peripheral surface of the mouth portion. A slide member provided so as to be slidable between the inward protrusion and the retaining protrusion.
The cap has a cap body having a threaded portion suitable for the threaded portion on the inner peripheral surface of the outer peripheral wall surrounding the mouth portion and a through hole in the top wall provided inside the outer peripheral wall, and the through hole. A base portion that is inserted into the cap body and slidably provided to the cap body, a top wall that is connected to the base portion above the top wall, and a flexibly provided base portion and the inward protrusion. With a locking member having a locking claw that engages and prevents it from coming off
With the cap attached to the container, by sliding the lock member downward, the locking claw is held by the slide member in a state of being bent inward, and the screw portion and the screwed portion are held together. By rotating the cap body in a loosening direction, the top wall abuts on the top wall and the lock member is pulled up, and accordingly, the slide member also rises with the locking claw bent inward. On the other hand, when the ascending of the slide member is stopped by the inward protrusion, the locking claw is a container with a cap configured to be pulled up while leaving the slide member to get over the inward protrusion.

The slide member preferably has a first convex portion that engages with the locking claw in a bent inward direction.

When the lock member is slid downward, the lock member is caught by the inward protrusion at a position where the locking claw is held by the slide member in a state of being bent inward, and the lock member is lowered. It is preferable to have a second convex portion for stopping the.

The cap main body is caught by the second convex portion when the cap main body is rotated in a direction in which the screw portion and the screwed portion are tightened, and the third convex portion that moves the lock member downward together with the cap main body. It is preferable to have.

The locking claw is inclined to induce the locking claw to get over the inward protrusion when the second convex portion is caught by the third convex portion and the locking member moves downward together with the cap body. It is preferable to have a portion.

The cap in the present invention is composed of a cap body having a through hole in the top wall provided inside the outer peripheral wall and a lock member having a base inserted through the through hole and slidably provided with respect to the cap body. As a result, the cap does not become large because it does not have a double structure in which the outer lid and the inner lid are combined as in the conventional case. Further, even if the cap attached to the container is rotated as it is, the locking claw of the lock member engages with the inward protrusion of the container to prevent it from coming off and is held, so that the cap body does not come off. When removing the cap, the lock member may be slid downward first, so that the locking claw engaged with the inward protrusion is held by the slide member in a state of being bent inward. When the lock member is pulled up by rotating the cap body in the loosening direction, the slide member also rises with the locking claw bent inward, while when the slide member stops rising due to the inward protrusion, the locking claw also rises. Will be pulled up while leaving the slide member to get over the inward protrusion. That is, since the locking claw and the inward protrusion are disengaged, the cap can be removed from the container.

It is a figure which shows the state which the locking claw got over the inward protrusion and the cap was removed from a container. It is a figure which shows the state which the child resistance function is exerted, and the removal of a cap is prevented.

Hereinafter, an embodiment of a container with a cap according to the present invention will be described with reference to the drawings. The relationship between "upper" and "lower" in the present specification and the like refers to the orientation of the container when it is placed on a horizontal plane.

As shown in FIG. 1, the capped container of the present embodiment includes a container 1 and a cap 5. The container 1 of the present embodiment is composed of a container body 2, an inner plug 3, and a slide member 4. Further, the cap 5 is composed of a cap body 6 and a lock member 7.

As shown in FIG. 1, the container body 2 has a disk-shaped bottom portion 2a, a cylindrical body portion 2b integrally connected to the outer edge portion of the bottom portion 2a, and a radial inward direction from the upper end portion of the body portion 2b. It is provided with a shoulder portion 2c extending while tilting, and a cylindrical mouth neck portion 2d that is integrally connected to the shoulder portion 2c and is open upward. Further, a screw portion 2e formed as a male screw is provided on the outer peripheral surface of the mouth neck portion 2d.

The inner plug 3 is provided inside the mouth neck 2d, and has a cylindrical cylinder wall 3a extending along the inner peripheral surface of the mouth neck 2d and a cylindrical wall 3a extending radially inward from the cylinder wall 3a. It is provided with an inwardly projecting protrusion 3b that projects vertically. Further, at the connecting portion between the tubular wall 3a and the inward protrusion 3b, a claw-shaped retaining protrusion 3c extending downward and having a lower end protruding inward in the radial direction is spaced apart in the circumferential direction. It is provided. As shown in FIG. 2B, a total of four retaining protrusions 3c of the present embodiment are provided at equal intervals in the circumferential direction. Further, a flange portion 3d extending outward in the radial direction is provided at the upper end portion of the cylinder wall 3a.

The slide member 4 generally has an annular shape. A convex portion (first convex portion) 4a projecting inward in the radial direction is provided at the upper end portion of the inner peripheral surface of the slide member 4. Further, on the outer peripheral surface of the slide member 4, an outer inclined portion 4b that inclines inward as it goes upward is provided at the upper end portion thereof, and an adjacent retaining portion 4b is provided at the lower end portion thereof as shown in FIG. 2 (b). A protrusion 4c located between the protrusions 3c and projecting outward in the radial direction is provided.

Such a container body 2, an inner plug 3, and a slide member 4 press the slide member 4 from below the inner plug 3 to fit them together, and further insert them from above the mouth neck 2d to form a container. Assembled as 1. Here, when the slide member 4 is fitted to the inner plug 3, the retaining protrusion 3c is guided by the outer inclined portion 4b so as to bend outward in the radial direction, so that the assembling work can be smoothly performed. Further, the slide member 4 is prevented from rotating by locating the protrusion 4c between the adjacent retaining protrusions 3c, and is slidably held between the inward protrusion 3b and the retaining protrusion 3c. In the present embodiment, the container body 2 and the inner plug 3 are different members, but these may be composed of one member. Further, in the present specification and the like, the mouth portion of the container 1 refers to the combined mouth and neck portion 2d and the inner plug 3.

The cap body 6 includes a cylindrical outer peripheral wall 6a that surrounds the mouth neck 2d. A threaded portion 6b formed as a female thread is provided on the inner peripheral surface of the outer peripheral wall 6a. Further, inside the outer peripheral wall 6a, an inward flange 6c extending radially inward from the upper end portion of the outer peripheral wall 6a, and extending downward from the inner edge portion of the inward flange 6c, and then in the radial direction. A top wall 6d extending inward and an annular wall 6e extending downward from the lower surface of the top wall 6d are provided. Here, in the central portion of the top wall 6d, a through hole 6f that penetrates the top wall 6d in the vertical direction is provided. Further, the top wall 6d includes a convex portion (third convex portion) 6 g that projects inward in the radial direction from the connecting portion with the annular wall 6e. The inner edge of the inward flange 6c is provided with a convex portion (fourth convex portion) 6h that projects inward in the radial direction.

The lock member 7 includes a cylindrical base portion 7a that is inserted into the through hole 6f. A disc-shaped top wall 7b is provided at the upper end of the base portion 7a. Further, on the outer peripheral surface of the base portion 7a, a convex portion (second convex portion) 7c that protrudes outward in the radial direction is provided. As shown in FIG. 2A, a total of four second convex portions 7c in the present embodiment are provided at equal intervals in the circumferential direction. A locking claw 7e is provided at the lower end of the base portion 7a so as to be integrally connected to the base portion 7a via a thin-walled portion 7d and to project outward in the radial direction. With such a thin portion 7d, the locking claw 7e can be bent in the radial inward and outward directions with respect to the base portion 7a. As shown in FIG. 2B, a total of four locking claws 7e of the present embodiment are provided at equal intervals in the circumferential direction. Further, the lower surface of the locking claw 7e is provided with an inclined portion 7f that inclines inward as it goes downward.

Such a cap body 6 and a lock member 7 are capped by inserting a locking claw 7e into the through hole 6f from above and pushing the lock member 7 until the second convex portion 7c gets over the third convex portion 6g. Assembled as 5. A fourth convex portion 6h is provided on the inner edge portion of the inward flange 6c, and the top wall 7b can be lightly fitted to the fourth convex portion 6h. Therefore, the cap body 6 has an inward flange 6c. The lock member 7 can be held in a state where the top wall 7b and the top wall 7b are aligned.

Then, when the cap 5 is attached to the container 1 described above, as shown in FIG. 3, the cap 5 is put on the container 1 and the cap body 6 is rotated in the direction in which the screw portion 2e and the screw portion 6b are tightened. As a result, the cap body 6 moves downward. At this time, since the second convex portion 7c is pushed downward by the third convex portion 6g, the lock member 7 also moves downward together with the cap body 6. Here, an inclined portion 7f is provided on the lower surface of the locking claw 7e, and when the locking claw 7e comes into contact with the inward protrusion 3b, the locking claw 7e is guided by the inclined portion 7f and bends inward. Therefore, the locking claw 7e can easily get over the inward protrusion 3b. Therefore, as shown in FIG. 1, the cap body 6 can be rotated to the end, so that the container 1 can be reliably closed.

Further, when removing the cap 5 from the container 1, the lock member 7 is pushed downward as shown in FIG. 4, and the lock member 7 is slid downward with respect to the cap body 6. As a result, the locking claw 7e gets over the first convex portion 4a of the slide member 4 and is held by the slide member 4 in a state of being bent inward. When the lock member 7 is slid, the second convex portion 7c is caught by the inward protrusion 3b, so that the lock member 7 that slides downward can be stopped at a predetermined position.

Then, as shown in FIG. 5, when the cap body 6 is rotated in the direction in which the screw portion 2e and the threaded portion 6b are loosened, the cap body 6 rises with respect to the container body 2 and the top wall 6d hits the top wall 7b. The lock member 7 is pulled up together with the cap body 6 in contact with the cap body 6. Along with this, the slide member 4 that holds the locking claw 7e in a bent state is also pulled up. Since the locking claw 7e is engaged with the first convex portion 4a, the slide member 4 can be reliably pulled up.

Then, when the rotation of the cap body 6 is continued, as shown in FIG. 6, the slide member 4 is hindered from being raised by the inward protrusion 3b, so that the lock member 7 is further raised while leaving the slide member 4. As a result, the locking claw 7e gets over the first convex portion 4a and further gets over the inward protrusion 3b, so that the cap 5 can be removed from the container 1 as shown in FIG.

By the way, when the lock member 7 is pushed in and the cap body 6 is rotated in this way, the cap 5 can be removed from the container 1, while the lock member 7 is not pushed in and only the cap body 6 is loosened as shown in FIG. Even when rotated in the direction, the locking member 7 remains held in the container 1 because the locking claw 7e is engaged with the inward projection 3b. Therefore, even if the threaded portion 2e and the threaded portion 6b are disengaged, the cap body 6 does not come off from the container 1 because the top wall 6d is caught by the top wall 7b and idles. That is, it is possible to prevent a problem that the container 1 is accidentally opened by an infant or the like.

As described above, according to the container with a cap of the present embodiment, the cap body 6 cannot be removed unless the lock member 7 is pushed and then the cap body 6 is rotated. It is also possible to prevent the opening of the cap. Further, for example, if the lock member 7 is strongly held by adjusting the gap between the members so that the lock member 7 is not easily pushed by the force of an infant or the like, the child resistance function can be more reliably exerted. It is possible.

The container with a cap according to the present invention is not limited to the embodiments described so far, and includes those with various modifications within the scope of the claims. For example, the locking claw 7e of the lock member 7 is flexed by the thin portion 7d whose wall thickness is locally thinned, but the locking claw 7e may be configured to be flexed by being thinned as a whole. ..
