Thereby, the lid body 9 can be rotated in the opening direction by the elastic pressure of the elastic member in the hinge portion 27.

Referring to FIGS. 1 to 3, on the other hand, in the lid locking mechanism 10, when the lid body 9 closes the upper portion of the cap body 8, the end receiving portion 43 is hooked by the annular stopper portion 39, The rotation in the opening direction of the lid body 9 is stopped. Thereby, in the lid lock mechanism 10, the cover 9 can be prevented from being opened by unnecessary operation of the lock member 38.

As described above, as shown in FIGS. 1 to 3, in the beverage container 1 having the cap structure 3 of the present embodiment, the lid spacer 28 is removed from the lid body 9 (inner wall portion 9c). And the cover member 29 is removed from the cover 9 (top wall portion 9b), whereby the cleaning cap structure 3 can be easily disassembled. In addition, in the state in which the lid portion 28 and the lid member 29 are removed, the lid body 9 is in a state in which the inner wall portion 9c penetrates the top wall portion 9b. Therefore, the lid body 9 has a structure in which the water is drained during washing and is easily dried.

Further, in the cap structure 3 of the present embodiment, the hinge portion 21 of the locking member 18 or the elastic piece 20 is configured to include no metal parts. Therefore, when the drinking opening forming member 13 which is removed from the cap body 8 is cleaned, it can be cleaned using a chlorine bleach or the like.

Referring to FIGS. 1 to 3, in the cap structure 3 of the present embodiment, the shaft hole 22 on the side of the drinking port forming member 13 is fitted by the support shaft 19 on the side of the locking member 18. The hinge portion 21 is formed, and further, since the elastic piece 20 is formed integrally with the locking member 18, Reduce the number of parts and simplify the construction.

In addition, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit and scope of the invention. Specifically, the beverage container 1 may be replaced with the cap structure 3, for example, as shown in FIG. Further, Fig. 7 is a perspective view showing the cutting of the cap structure 3A in the front-rear direction. In the following description, the same portions as those of the above-described cap structure 3 will be omitted, and the same reference numerals are used in the drawings.

Referring to Fig. 7, the cap structure 3A is provided with a cover spacer 28A instead of the cover spacer 28 (shown in Fig. 1). Specifically, the lid gasket 28A is a bottomed cylindrical sealing member, and the lid gasket 28A is detachably attached to the hollow portion 28h inside the lid gasket 28A. It is attached to the inner wall portion 9c.

In addition, as shown in Fig. 7, the base end portion of the inner wall portion 9c is formed such that the engaged piece 9e constituting the cover attaching and detaching mechanism 31 projects rearward. Thereby, in a state in which the stopper portion 34 is inserted into the fourth engaged portion (hole portion) 36, the fourth claw portion 33 is locked to the engaged piece 9e.

Referring to Fig. 7, next, in the lid lock mechanism 10, an elastic member (indicated by reference numeral 41) made of a synthetic resin such as a silicone resin is used instead of the coil spring (spring member) 41.

Referring to FIG. 7, the cover gasket 28A includes a subsequent structure: an upper tubular portion 28e having a cylindrical shape; and a lower tubular portion 28f having a bottomed cylindrical shape and located at the upper tubular portion. Below the 28e. The lid spacer 28A has a shape in which the inner diameter of the upper tubular portion 28e is reduced to be smaller than the inner diameter of the lower tubular portion 28f (cavity portion 28h). The bottom surface of the lower tubular portion 28f is formed in a dome shape. On the other hand, in A flange portion 28g is provided on the outer peripheral portion of the upper side of the lid spacer 28A. The flange portion 28g is provided to protrude in the diameter increasing direction over the entire circumference of the outer peripheral portion.

Referring to Fig. 7, the inner wall portion 9c has an upper tubular portion 9f having a cylindrical shape, and a lower tubular portion 9g having a cylindrical shape and located therein, as shown in Fig. 7. Below the upper tubular portion 9f. The inner wall portion 9c has a shape in which the outer diameter of the upper tubular portion 9f is increased to a larger diameter than the outer diameter of the lower tubular portion 9g.

As shown in Fig. 7, the cover spacer 28A is detachably attached to the inside of the cavity portion 28h (upper tubular portion 28e) by firmly fitting the inner wall portion 9c (upper tubular portion 9f) In the cover body 9. Thereby, in the cap structure 3A, the inside of the container body 2 is under a negative pressure, and even when the cap spacer 28A generates the force in the stretching direction, the cap spacer 28A can be prevented from the inner wall portion when the lid body 9 is opened. 9c falls off. On the other hand, the inside of the container main body 2 is positively pressed, and even if the lid portion spacer 28A generates a force in the pressing direction, the flange portion 28g of the lid portion spacer 28 abuts against the base end portion of the inner wall portion 9c, thereby preventing the inside. The wall portion 9c is more embedded inside the cover spacer 28A. Further, since the cover spacer 28A has the above-described axial symmetry shape, the attachment direction can be easily attached to the inner wall portion 9c. Further, the flange portion 28g may be omitted.

In addition, the beverage container 1 is not limited to the above-described external shape, and can be appropriately changed in accordance with the size, function, design, and the like.

Further, the present invention can be applied to a beverage container 1 having a temperature and a cold keeping function by using the container body 2 having the vacuum heat insulating structure described above, but is not limited to the use of the above vacuum partition. The container body 2 of the heat construction. That is, the present invention can be widely applied to a beverage container in which the cap structure is detachably attached to the neck of the container body.

According to the above, it is only a preferred embodiment of the present invention, but the present invention is The scope of the present invention is not limited thereto, and those skilled in the art, based on the technical content disclosed in the present invention, can easily think of equivalent changes, and should not fall within the protection scope of the present invention.
