Therefore, in this state, dust, dust, and the like are unlikely to accumulate in the lid body 2, and the lid body 2 is held in a sanitary manner.

  The present invention is not limited to the above-described embodiment, and can be implemented with various modifications. For example, the container in which the cap is used is not limited to a beverage container, and may be a container used to store a liquid that is not a beverage.

  In addition, the cap is not limited to the one having the packing 7, for example, instead of the packing 7, a liner integral with the lid main body 2 (the upper surface of the container mouth 1 without the middle foot inserted into the container mouth 1). 2 may be provided, and the lid body 2 may be provided with a portion corresponding to the middle leg 9 of the packing 7 instead of having the packing 7.

  Further, the locking member 16 is not limited to a bellows ring shape.

  Further, the engagement portion 19 may be provided in a plurality instead of only one.

  Further, as shown in FIG. 6 (A), the engaging portion 19 may be configured by only the two cutout portions 20 and 21. In this case, as shown in FIG. 6B, the notches 20 and 21 may be substantially slit-shaped. The latter configuration is particularly suitable when the lid body 2 of the cap is made of metal and the peripheral wall 4 is extremely thin.

For example, as shown in the reference view shown in FIG. 6C, when the engaging portion 19 is formed by providing a notch in the center of the side surface of the band 14, the engaging portion 19 is shown in FIG. as reference diagram shown in (D) and (E), Ri Do notched shape as in a state of leaving a projection 23 extending upwardly from the approximate center of its lower periphery, and as the shape of the protrusions 23, Various shapes such as a mountain shape (see FIG. 6D) and a square shape (see FIG. 6E) can be given. As shown in FIGS. 6D and 6E, when the engaging portion 19 has the protrusion 23, the lid body 2 engaged with the engaging portion 19 is more difficult to come off.

Here, as described above, when the engagement portion 19 is configured by providing the notch and the protrusion 23 at the center of the side surface of the band 14, it is not necessary for the peripheral wall 4 inserted into the engagement portion 19. In order to prevent excessive force from being applied, the notches and the corners of the protrusions 23 are rounded as shown in the reference diagram of FIG .

  Further, the engaging portion 19 is not limited to the one formed by providing a notch in which a part of the band 14 is completely removed. For example, as shown in FIG. You may be comprised by providing a hollow as a shape (thin film shape). That is, as described above, if the engaging portion 19 is configured as a shape in which a part of the side wall of the band 14 is penetrated or cut off, that is, a notch shape, the first portion of the peripheral wall 4 of the lid body 2 with respect to the engaging portion 19 There is no need to break the engaging portion 19 at the time of engagement, and the engaging portion 19 can be easily formed in terms of molding or processing. On the other hand, if the engaging part 19 is made thin, a part of the container mouth part 1 can be reliably prevented from being exposed to the outside through the engaging part 19, and a more favorable effect in terms of hygiene can be obtained.

  In addition, the engagement portion 19 includes, for example, a notch or a recess provided in the band 14 having a through hole, a groove, or a cut-off shape portion provided in the band 14, and a protrusion or the like in the inside thereof. Those having various shapes, such as those having, are also included, and those formed by appropriately combining these are also included.

  Moreover, although the engaging part 19 of embodiment shown in FIGS. 1-5 may extend substantially horizontally, it is made to respond | correspond to a part of lower end part 4a of the surrounding wall 4 of the lid body 2 being circular arc shape. Alternatively, it may have a convex arc shape.

  Moreover, although the engaging part 19 shown to FIG.6 (C)-(F) is extended substantially horizontal, it respond | corresponds to a part of lower end part 4a of the surrounding wall 4 of the lid body 2 being circular arc shape. An upward convex arc shape or a downward convex arc shape may be employed. When the lid main body 2 is engaged with the engaging portion 19 in a direction (the direction shown in FIGS. 4 and 5) in which the inner space is opened only substantially downward, the engaging portion 19 is An upwardly convex arc shape is suitable, and conversely, the lid body 2 is oriented so that the inner space is only opened upward (up and down relative to the orientation shown in FIGS. 4 and 5). When engaging with the engaging portion 19 in the opposite direction), it is suitable that the engaging portion 19 has a downwardly convex arc shape. Accordingly, when the projection 23 is provided on the engagement portion 19, the projection 23 is formed so as to extend upward from substantially the center of the lower periphery of the engagement portion 19 with respect to the engagement portion 19 having a downwardly convex arc shape. It is desirable to provide the engaging portion 19 having an upward convex arc shape, and it is desirable to provide the protrusion 23 so as to extend downward from substantially the center of the upper peripheral edge of the engaging portion 19.

  Further, when the engaging portion 19 having the protrusion 23 shown in FIG. 6F is provided as the engaging portion 19, only the lid body 2 after opening is shown in FIG. 8 (the band 14 is omitted). ), If the annular groove 24 is provided on the lower inner side of the peripheral wall 4 of the lid body 2, the engagement of the peripheral wall 4 with the engaging portion 19 can be performed better. That is, in this case, as shown in FIGS. 9A and 9B, in a state where the lower end portion 4 a of the peripheral wall 4 is locked to the engaging portion 19, it is provided on the engaging portion 19. Since the convex protrusion 23 is locked in the groove 24, the engagement between the peripheral wall 4 and the engaging portion 19 is performed more stably and reliably.

  This also applies to the case where an annular protrusion 25 is provided inside the lower portion of the peripheral wall 4 of the lid body 2 as shown in FIGS. 10 (A) and 10 (B). That is, when the protrusion 25 is provided, as shown in FIG. 10B, the protrusion 25 is provided in the engagement portion 19 in a state where the lower end portion 4 a of the peripheral wall 4 is engaged with the engagement portion 19. Furthermore, since the convex protrusion 23 is locked to the protrusion 25, the engagement between the peripheral wall 4 and the engaging portion 19 is performed more stably and reliably.

  Here, as the engaging portion 19 for engaging the peripheral wall 4 having the groove 24 or the protrusion 25, the notch and the corner of the protrusion 23 are rounded as described above, as shown in FIG. The joint portion 19 is most suitable, but is not limited to this, and if the engaging portion 19 has a protrusion that protrudes upward or protrudes downward, the peripheral wall 4 having the groove 24 or the protrusion 25 can be satisfactorily engaged. Can be combined. As such an engaging part 19, in addition to the engaging part 19 shown in FIG. 6F, for example, the engaging part 19 shown in FIG. 1 and FIG. 6 (A) and 6 (B), the engagement portion 19 (the portion between the two cutout portions 20 and 21 corresponds to an upward projection), FIG. 6 (D) and FIG. 6 (E). And the engagement portion 19 (the projection 23 corresponds to a projection protruding upward).

  The cap configured as described above has almost the same appearance as the conventional cap, and in particular, there are no new protrusions or the like protruding outward, so that, for example, in the filling process and the capping process, the conventional (existing) ) Equipment for manufacturing caps (containers) can be used as they are. In addition, the consumer can handle the cap in the same manner as a conventional cap when opening and closing the container.
