JP, 2016-204021, A

  By the way, in this type of capped container, as disclosed in Patent Document 1, it is general to use a double-structured cap in which an outer lid and an inner lid are combined. That is, since the double structure makes the cap large, even if it is intended to replace the conventionally used cap with a cap having a child resistance function, the image of the previous appearance is largely changed. In addition, if it is necessary to make the outer lid and the inner wall smaller so as to approach the size of the cap used conventionally, it is necessary to make the mouth of the container thinner, and it becomes necessary to use a dedicated container. There is a problem with

  An object of the present invention is to solve such a problem, and it is an object of the present invention to provide a capped container which can have a child resistance function without increasing the size of the cap.

The present invention is a capped container comprising a container having a mouth opening upward and a cap attached to the mouth, the container comprising:
The container is spaced from the inward projection on the inner circumferential surface of the opening, and the screw portion provided on the outer circumferential surface of the opening, the inward projection provided on the inner circumferential surface of the opening, And a slide member provided slidably between the inward projection and the projection.
The cap has a threaded portion adapted to the screw portion on an inner peripheral surface of an outer peripheral wall surrounding the opening, and a cap main body having a through hole on a top wall provided inside the outer peripheral wall; And a top wall connected to the base above the top wall, and a top wall which is flexible with respect to the base and the inward projection. And a lock member having a locking claw which is engaged and retained.
In the state where the cap is attached to the container, the locking claw is held by the slide member in a bent state by sliding the lock member downward, and the screw portion and the screw portion are By rotating the cap body in the loosening direction, the top wall comes in contact with the top wall and the lock member is pulled up, and accordingly the slide member ascends with the locking claw bent inward. On the other hand, when the elevation of the slide member is stopped by the inward projection, the locking claw is pulled up with the slide member remaining, and is configured to be pulled over the inward projection.

  It is preferable that the slide member has a first convex portion engaged with the locking claw bent inward.

  When the locking member is slid downward, the locking member is caught by the inward projection at a position held by the slide member in a state where the locking claw is bent inward and the descent of the locking member is lowered. It is preferable to have the 2nd convex part which stops.

  The cap main body is engaged with the second convex portion when the cap main body is rotated in a direction in which the screw portion and the threaded portion are tightened, and the third convex portion moves the lock member downward with the cap main body It is preferable to have

  The locking claw is inclined to guide the inward projection of the locking claw against the inward projection when the second convex portion is caught by the third convex portion and the lock member moves downward with the cap main body. It is preferable to have a part.

  The cap in the present invention comprises a cap body having a through hole in a ceiling wall provided inside the outer peripheral wall, and a lock member having a base inserted through the through hole and provided slidably with respect to the cap body. Thus, the cap does not increase in size because it does not have a double structure in which the outer lid and the inner lid are combined as in the prior art. In addition, even if the cap attached to the container is rotated as it is, the locking claw of the locking member is engaged with the inward projection of the container and held so as not to come off. In order to remove the cap, it is sufficient to first slide the lock member downward, so that the locking claw engaged with the inward projection is held by the slide member while being bent inward. When the cap body is rotated in the loosening direction and the lock member is pulled up, the slide member ascends in a state in which the locking claw is bent inward, and when the rising of the slide member is stopped by the inward projection, the locking claw Is pulled up while leaving the slide member, and climbs over the inward projection. That is, the cap can be removed from the container since the engagement between the locking claw and the inward projection is released.

FIG. 18 is a view showing the state in which the locking claws get over the inward projection and the cap is removed from the container. It is a figure which shows the state in which the child resistance function was exhibited and removal of the cap was prevented.

  Hereinafter, an embodiment of a capped container according to the present invention will be described with reference to the drawings. In addition, the relationship of "upper" and "lower" in this specification etc. says direction in the state which mounted the container in the horizontal surface.

  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, a plug 3 and a slide member 4. 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 disc-shaped bottom 2a, a cylindrical body 2b integrally connected to the outer edge of the bottom 2a, and a radially inward direction from the upper end of the body 2b. It has a shoulder 2c extending in an inclined manner, and a cylindrical mouth and neck 2d integrally connected to the shoulder 2c and opened upward. Further, a screw portion 2e formed as a male screw is provided on the outer peripheral surface of the mouth and neck portion 2d.

  The inside plug 3 is provided on the inner side of the mouth and neck 2d, and extends inward in the radial direction from the cylindrical wall 3a extending along the inner circumferential surface of the mouth and neck 2d and the cylinder wall 3a. And an inwardly directed projection 3b. Further, at the connecting portion between the cylindrical wall 3a and the inward projection 3b, a claw-like retaining projection 3c which extends downward and whose lower end projects radially inward is spaced in the circumferential direction. Is provided. A total of four retaining projections 3c of this embodiment are provided at equal intervals in the circumferential direction as shown in FIG. 2 (b). Further, a flange portion 3d extending outward in the radial direction is provided at the upper end portion of the cylindrical wall 3a.

  The slide member 4 has a substantially annular shape. At an upper end portion of the inner peripheral surface of the slide member 4, a convex portion (first convex portion) 4 a that protrudes inward in the radial direction is provided. Further, on the outer peripheral surface of the slide member 4, an outer inclined portion 4b which inclines inward as it goes upward is provided at the upper end portion thereof, and as shown in FIG. A projection 4c is provided between the projections 3c and protrudes radially outward.

  The container body 2, the inner plug 3 and the slide member 4 press the slide member 4 from the lower side of the inner plug 3 to fit them together and further insert the container from above the mouth and neck 2d. Assembled as one. Here, when the slide member 4 is fitted to the inner plug 3, the retaining projection 3c is guided to be bent radially outward by the outer inclined portion 4b, so that the assembling operation can be smoothly performed. Further, the slide member 4 is locked by the positioning of the projection 4c between the adjacent locking projections 3c, and is slidably held between the inward projection 3b and the locking projection 3c. In addition, in this embodiment, although the container main body 2 and the inner plug 3 are different members, you may comprise these with one member. Further, in the present specification and the like, the mouth of the container 1 indicates the combined mouth and neck 2 d and the inside plug 3.

  The cap body 6 is provided with a cylindrical outer peripheral wall 6a surrounding the mouth and neck 2d. A threaded portion 6b formed as a female screw is provided on the inner peripheral surface of the outer peripheral wall 6a. Further, an inward flange 6c extending radially inward from the upper end of the outer peripheral wall 6a to the inside of the outer peripheral wall 6a and a downward direction from the inner edge of the inward flange 6c A ceiling wall 6d extending inward and an annular wall 6e extending downward from the lower surface of the ceiling 6d are provided. Here, in the central portion of the ceiling wall 6d, a through hole 6f penetrating the ceiling wall 6d in the vertical direction is provided. Further, the ceiling wall 6d is provided with a convex portion (third convex portion) 6g which protrudes inward in the radial direction from a connecting portion with the annular wall 6e. And the convex part (4th convex part) 6h which protrudes toward radial direction inner side is provided in the inner edge part of the inward flange 6c.

  The lock member 7 includes a cylindrical base 7 a which is inserted into the through hole 6 f. A disk-shaped top wall 7b is provided at the upper end of the base 7a. Moreover, the convex part (2nd convex part) 7c which protrudes toward radial direction outer side is provided in the outer peripheral surface of the base 7a. 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. The lower end portion of the base 7a is provided with a locking claw 7e integrally connected to the base 7a via the thin portion 7d and projecting radially outward. The locking claw 7e can be bent in the radially inward / outward direction with respect to the base 7a by such a thin portion 7d. 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, on the lower surface of the locking claw 7e, an inclined portion 7f which is inclined inward as it goes downward is provided.

  Such cap body 6 and lock member 7 insert the locking claw 7e from above into the through hole 6f, and push the lock member 7 until the second convex portion 7c gets over the third convex portion 6g. Assembled as 5. In addition, since the fourth convex portion 6h is provided at the inner edge portion of the inward flange 6c, and the fourth convex portion 6h can lightly fit the top wall 7b, the cap main body 6 is the inward flange 6c. The lock member 7 can be held with the top wall 7b aligned.

  Then, when attaching the cap 5 to the container 1 described above, as shown in FIG. 3, the cap 5 is put on the container 1 and the cap main body 6 is rotated in the direction in which the screw portion 2e and the threaded portion 6b are tightened. The cap body 6 is thereby moved 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, the inclined portion 7f is provided on the lower surface of the locking claw 7e, and when the locking claw 7e abuts on the inward projection 3b, the locking claw 7e is guided by the inclined portion 7f and is bent inward. Therefore, the locking claw 7e can easily get over the inward projection 3b. Therefore, since the cap main body 6 can be rotated to the end as shown in FIG. 1, the container 1 can be reliably closed.

  Further, when removing the cap 5 from the container 1, as shown in FIG. 4, the lock member 7 is pushed downward and the lock member 7 is slid downward with respect to the cap main body 6. As a result, the locking claw 7 e passes over the first convex portion 4 a 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 hooked on the inward projection 3b, so that the lock member 7 sliding 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 screwed portion 6b are loosened, the cap body 6 is raised with respect to the container body 2 and the top wall 6d contacts the top wall 7b. At the same time, the lock member 7 is pulled up together with the cap body 6. Along with this, the slide member 4 which holds the locking claw 7e in a bent state inward is also pulled up. In addition, since the locking claw 7e is engaged with the first convex portion 4a, the slide member 4 can be pulled up reliably.

  Then, when the rotation of the cap body 6 is continued, as shown in FIG. 6, since the slide member 4 is prevented from rising by the inward projection 3b, the lock member 7 is further raised while the slide member 4 is left. As a result, since the locking claw 7e gets over the first convex portion 4a and further gets over the inward projection 3b, 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 main body 6 is rotated, the cap 5 can be removed from the container 1, but as shown in FIG. 8, only the cap main body 6 is loosened without pushing the lock member 7. Even when rotated in the direction, the locking member 7 remains held by the container 1 because the locking claw 7e is engaged with the inward projection 3b. For this reason, even if the engagement between the screw portion 2e and the screwed portion 6b is released, the cap body 6 is not removed from the container 1 since the top wall 6d is merely caught on the top wall 7b and turned idle. That is, it is possible to prevent the 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, since the cap body 6 can not be removed unless the lock member 7 is pressed and then the cap body 6 is rotated, it is impossible for the infant etc. Opening can also be prevented. Further, for example, if the lock member 7 is held strong by adjusting the gap between the members and the lock member 7 is not easily pushed in by a force of an infant or the like, the child resistance function can be more surely exhibited. It is possible.

  In addition, the capped container according to the present invention is not limited to the embodiments described above, and includes those to which various modifications are made within the scope of the claims. For example, although the locking claw 7e of the locking member 7 is configured to be flexed by the thin portion 7d having a small thickness locally, the locking claw 7e may be configured to be flexed by being thinned as a whole. .
