[0008]
DETAILED DESCRIPTION OF THE INVENTION
First, a conventionally known structure will be briefly described. Reference numeral 1 denotes a cap body, which hangs the outer peripheral wall 3 from the outer periphery of the top wall 2. Moreover, the inner peripheral wall 4 for fitting the container body mouth and neck is suspended from the lower surface of the top wall. In the illustrated example, the inner peripheral wall is formed by a seal cylinder 4a fitted to the inner surface of the mouth-neck part and a holding cylinder 4b fitted to the outer surface of the mouth-neck part. The upper end portion of the cap body has a small outer diameter portion 6 through an upward stepped portion 5, and a nozzle 7 as a stored item takeout hole is raised from the front portion of the top wall 2.
[0009]
Both the left and right parts of the cap body are provided with split grooves 8 and 8 so that the upward stepped portion forming portion 5a and the outer surface and the upper surface of the small outer diameter portion forming portion 6a above the upper portion are formed as outer peripheral wall forming portions. The pushbuttons 9 and 9 which have 3a upper part are formed, and the engaging claws 10 and 10 are laterally arranged on the outer surface of the upper end part of both pushbuttons.
[0010]
An auxiliary lid 13 for fitting the peripheral wall 12 to the small outer diameter portion 6 through a thin hinge 11 is attached to the rear portion of the cap body. The auxiliary lid hangs the peripheral wall 12 from the outer periphery of the top plate 14, and a seal cylinder for fitting to the nozzle 7 is suspended from the lower surface of the top plate and rotated around the hinge 11 to reduce the peripheral wall 12. The outer cylinder 6 can be attached to and detached from the outer surface of the outer diameter portion 6 and the outer surface of the nozzle 7. Furthermore, the left and right portions of the peripheral wall 12 are provided with locking portions 16 and 16 formed by horizontally long holes, and when the auxiliary lid is closed, the aforementioned engaging claws 10 and 10 are engaged with the locking portions and the auxiliary lid. 13 can no longer be opened, and the upper part of the pushbuttons 9 and 9 is elastically deformed and pushed inward from the cap body so that the engaging claws 10 and 10 can be pulled out as shown in FIG. It is said.
[0011]
The structure of the present invention will be described below. First, the first embodiment shown in FIGS. 1 to 7 will be described. The front and rear surfaces of the outer peripheral wall forming portions 3a and 3a of the push button and the front and rear surfaces of the outer peripheral wall portion of the cap body facing the front and rear surfaces are shown in FIG. In the vertical direction, the elastic pieces 17 and 17 that are inclined in the vertical direction when viewed from the outside are connected via thin-walled hinges and elastically restored after the elastic pieces reach the dead center due to elastic deformation. Due to the elastic reversal, the push buttons 9, 9 can be moved relative to the cap body 1 by reversing in the vertical direction. As shown in FIGS. 16, the auxiliary lid 13 cannot be opened, and the push buttons 9, 9 are located below the lower end surface of the peripheral wall 12 of the auxiliary lid plate in the downward movement position as shown in FIGS. 5 and 6. In this state, the auxiliary lid can be opened and closed freely. At this time, the lower surface of the push button should not be the same height as the lower surface of the outer peripheral wall of the cap body or may be positioned above.
[0012]
8 to 13 show a second embodiment. In this embodiment, the front and rear surfaces of the outer peripheral wall forming portions 3a and 3a of the push button described above and the front and rear surfaces of the cap main body outer peripheral wall portions 3a and 3a facing the front and rear surfaces are viewed from above as shown in FIG. The elastic plates 18 and 18 that are inclined to each other are connected via thin hinges, and by elastic reversal of these elastic plates, the push buttons 9 and 9 are formed so as to be elastically reversible in both the inside and outside of the cap body. Yes. Further, as shown in FIG. 9, when the push buttons 9, 9 are elastically reversed outward from the cap body, the engaging claws 10, 10 are engaged with the locking portions 16, 16 as shown in FIG. Therefore, the auxiliary lid 13 cannot be opened unless the upper part of the push button is bent inward of the cap body and the engaging claws 10 are removed from the engaging portions.
[0013]
When the push button portion between the elastic plates 18 and 18 is strongly pressed inward from the state shown in FIGS. 8 and 9, the elastic plates 18 and 18 are elastically reversed and the push buttons as shown in FIGS. 9 and 9 are elastically inverted to the inner side of the cap body, and in this state, as shown in FIG. 12, the engaging claws 10 and 10 are disengaged from the locking portions 16 and 16, so that the auxiliary lid 13 can be freely opened and closed in this state. It becomes.
[0014]
In each of the above-described embodiments, the push buttons 9 are provided on both the left and right sides of the cap body.
[0015]
14 to 16 show a third embodiment. In this embodiment, the push button 9 formed in the same manner as in the first embodiment is provided in the front part of the container body outer peripheral wall 3, and the locking part 16 is also provided in the front part of the auxiliary lid peripheral wall. . In this state, as shown in FIG. 15, since the engaging claw 10 is engaged with the locking portion 16 by closing the auxiliary lid 13, the lid cannot be opened as it is, and the upper part of the push button 9 is pushed inward and elastically The auxiliary lid can be opened by elastically deforming the piece 17 and removing the engaging claw 10 from the locking portion 16.
[0016]
When used as a non-safety cap, as shown in FIG. 16, the push button 9 is pushed down, the elastic piece 17 and the push button 9 are elastically inverted downward, and the locking claw 10 is moved below the lower surface of the auxiliary lid peripheral wall 12. Let Therefore, in this state, the locking claw 10 does not engage with the locking portion 16, and the auxiliary lid can be freely opened and closed.
[0017]
17 to 19 show a fourth embodiment. In this embodiment, the push button 9 provided in the same manner as in the second embodiment is provided in the front portion of the outer peripheral wall 3 of the cap body, and the locking portion 16 is also provided in the front portion of the auxiliary lid peripheral wall 12. .
[0018]
When the auxiliary cover 13 is closed in the state shown in FIG. 18 in which the push button 9 is elastically reversed outward, the engaging claw 10 is engaged with the locking portion 16, and in this state, the upper part of the push button 9 is directed to the inner side of the cap. The lid cannot be opened unless it is pushed in and the engaging claw 10 is removed from the locking portion 16.
[0019]
When used as a non-safety cap, as shown in FIG. 19, the elastic plate 18 and the push button 9 are elastically inverted toward the inner side of the cap. Then, since the engaging claw 10 moves to a position disengaged from the locking portion 16, the auxiliary lid 13 can be freely opened and closed.
[0020]
The third embodiment is the same as the first embodiment, and the fourth embodiment is the same as the second embodiment except for the above parts. The same parts are denoted by the same reference numerals, and the description thereof is omitted. To do.
[0021]
Each of the safety caps with the auxiliary lid described above is integrally molded with a synthetic resin material.
[0022]
【The invention's effect】
The present invention has the above-described configuration, and can be arbitrarily selected and used as a safety cap or a non-safety cap as described in claims 1 to 4.
[0023]
In addition, since the elastic reversal of each push button 9 in the vertical direction or inward / outward direction is performed by elastic reversal of the elastic pieces 17 or elastic plates 18 provided on both sides of the push button, it can be positioned at the movement position of each push button. Unless the elastic reversal is artificially reversed, there is no possibility that the safety cap becomes a non-safe cap or the non-safe cap becomes a safety cap.
