[0008]

FIG. 1 is a sectional view of a main part of a container with a cap showing an embodiment of the present invention. This container with a cap
As shown in FIG. 2, the container body 1 includes a plastic tubular container body 1 and a plastic cap 2 attached to a neck 4 of the container body 1. As shown in FIGS. 3 and 4, the container body 1 includes a tubular body 3 and a cylindrical neck 4 erected on the upper surface (shoulder) of the body 3. As shown in FIGS. 5 and 6, the neck 4 has an upper end portion having an annular engaging portion 4b protruding from the outer peripheral surface, a central portion having a threaded portion 4a formed on the outer peripheral surface, and a lower portion. The lower end is formed with a large-diameter side and a small-diameter step on the upper side, and engagement projections 5 are formed on the left and right sides of the lower end.

As shown in FIG. 1, the cap 2 includes a ceiling plate 6 and an outer cylinder 7 suspended from an outer peripheral edge of the ceiling plate 6.
And an inner cylinder (cylindrical body) 8 suspended from the center of the ceiling plate 6, and on the inner peripheral surface of the inner cylinder 8, on the thread 4 a of the neck 4 of the container body 1. A threaded portion 8a is formed. As shown in FIG. 7, the inner cylinder 8 is formed with a set of stopper portions 9 and elastic members 10 on the left and right sides of the outer peripheral surface thereof, respectively. As shown in FIGS. 8 to 10, the both stopper portions 9 are formed of a vertically long plate-like body, and the upper edge of the inner cylinder 8 (that is, the ceiling plate 6).
The lower end edge 8b of the inner cylinder 8 is formed integrally with the outer peripheral surface of the inner cylinder 8 so as to protrude downwardly along the axis of the inner cylinder 8 between the lower end edge 8b and the lower end edge 8b. The lower end portion (the portion below the lower end edge 8b of the inner cylinder 8) 9
a is slightly inside the outer peripheral surface of the inner cylinder 8. The lower end 9a of the stopper 9 contacts the engaging projection 5 provided on the neck 4 of the container body 1 in a detent-like manner.

The two elastic members 10 have a vertically elongated ridge 10a integrally formed on the outer peripheral surface of the inner cylinder 8, and an inner surface formed in an arc shape. It comprises a substantially semicircular portion 10b connected to the ridge 10a, and the ridge 10a hangs along the axis of the inner cylinder 8 between the upper edge and the lower edge of the inner cylinder 8. In addition, the substantially semicircular portion 10b hangs along the axis of the inner cylinder 8 between the upper edge and the lower edge 8b of the inner cylinder 8 together with the ridge 10a, and the lower edge 8b of the inner cylinder 8 is The lower end portion (the lower portion of the lower end edge 8b of the inner cylinder 8) 10c is configured to abut on the engaging projection 5 so as to be able to get over it. That is, when the cap 2 is rotated in the lid closing direction after this contact, the lower end portion 10c is elastically deformed outward so that the lower end portion 10c can get over the engaging projection 5. The distance between the stopper portion 9 and the elastic portion 10 is set to be slightly shorter than the circumferential length of the engaging projection 5 of the neck portion 4. The engagement projection 5 can be engaged between the stopper 9 and the elastic body 10 while the engagement projection 5 is pressed by the side surface. In FIG. 9, 6a
Is an inner annular body protruding from the lower surface of the ceiling plate 6 of the cap 2, and 6b is an outer annular body.

An inner lid 11 is attached to the neck 4 of the container body 2. As shown in FIG. 11, the inner cover 11 has a ceiling plate 1 having a circular hole 12a for liquid circulation in the center.
2 and an outer cylinder 13 suspended from an outer peripheral edge of the ceiling plate 12.
And an inner cylinder 14 suspended from the center of the ceiling plate 12. The lower end of the inner peripheral surface of the outer cylinder 13 is
An annular engaged portion 13a which can be detachably engaged with the engaging portion 4b of the neck portion 4 is formed so as to protrude, and the cap 2 is closed at the time of closing the cap 2 at the outer peripheral portion of the round hole 12a on the upper surface of the ceiling plate 12. Annular body 12b in liquid-tight contact with the lower end of inner annular body 6a
Are formed to protrude. When the lid is closed, the outer peripheral portion of the upper surface of the ceiling plate 6 is in liquid-tight contact with the lower end portion of the outer annular body 6b of the cap 2.

In the above configuration, when the lid is closed, the screw portion a of the inner cylinder 8 of the cap 2 is engaged with the screw portion 4a of the neck portion 4 of the container body 1, and the cap 2 is rotated in the lid closing direction. Is performed. Thereby, as shown in FIGS. 12 and 13, at the end of the closing rotation of the cap 2, the lower end portion 10 c of the elastic body portion 10 of the cap 2 is connected to the neck portion 4 of the container body 1.
As shown in FIGS. 14 to 16, the lower end 10c is elastically deformed and gets over the engaging projection 5 as shown in FIGS. At about the same time when the vehicle gets over, the lower end portion 9a of the stopper portion 9 comes into contact with the engaging projection 5 and is prevented from rotating. On the other hand, when opening the cover, the cap 2 in the closed state is rotated in the opening direction. Thereby, the lid is opened in a procedure reverse to the above operation.

As described above, in the above embodiment, since the stopper portion 9 does not act as a spring, the stopper portion 9 can be formed to have a correspondingly large thickness and can be made strong. For this reason, even when the cap 2 is erroneously rotated in the reverse direction, such as when the lid is opened, and a large load is applied to the stopper portion 9,
No damage. In addition, since the elastic body 10 and the stopper 9 are formed separately and are each integrally formed on the outer peripheral surface of the inner cylinder 8, the dimensional accuracy of the elastic body 10 and the stopper 9 is improved. Is not required to be high, and a high dimensional accuracy is not required for the mold for molding the cap 2. In addition, since the stopper portion 9 and the elastic body portion 10 are formed from the upper end edge to the lower end edge 8b of the outer peripheral surface of the inner cylinder 8, the area of a part integrally formed with the inner cylinder 8 is large, and The lower end 9a of the elastic body 10
Even if a considerably large load is applied to 10c or the like, they will not be damaged.

In the above embodiment, the engagement ridge 5 is formed to project from the neck 4 of the container body 1. However, the present invention is not limited to this. The protrusion may be formed.

Further, in the above embodiment, the interval between the stopper portion 9 and the elastic portion 10 is set to be slightly shorter than the circumferential length of the engaging projection 5 of the container body 1, but the present invention is limited to this. Instead, it may be set to be equal to or slightly longer than the circumferential length of the engaging projection 5.

[0016]

As described above, according to the container with the cap of the present invention, each stopper portion only abuts against each engaging projection to prevent rotation, and does not act as a spring. The thickness can be increased. Therefore, sufficient strength to each stopper portion can have a, even when applying a large load to each stopper portion and the like to rotate the cap in the opposite direction by mistake opened cover or the like, each <br/> The stopper will not be damaged. In addition, in the container with a cap of the present invention, each elastic body portion and each stopper portion are formed separately, and each is simply suspended from the outer peripheral portion of the cylindrical body. No high dimensional accuracy is required for the mold, and the mold is inexpensive.
