Description

[Detailed description of the invention] The present invention relates to a divine body safety device for air pots.

Conventionally, a lid with a built-in air pump 30 as shown in FIG. 1 has been used as a push body safety device for an air pot, that is, as a lock mechanism for the push body to prevent the content liquid from being discharged when the push body is erroneously pressed. A rotary plate 32 is provided inside the body 31, and by operating a lock lever 33 whose one end is engaged with the rotary plate 32, the rotary plate 32 can be rotated and the downward movement of the pushing body 34 can be restricted. is provided.

However, in this case, the rotating plate 32 and the lock lever 33
Since these are separate bodies, there are disadvantages in that the number of parts increases, the structure becomes complex, and assembly is difficult.

In order to solve the above-mentioned drawbacks, the lock lever is integrated with or directly interlocked with the push body, and the push body rotates at the same time as the lock lever is rotated, thereby regulating the downward movement of the push body provided on the lid body. A device has been devised that engages and disengages from the pusher piece to restrict the downward movement of the pusher.

However, in this case, the pusher itself is rotatable, so if you accidentally turn the pusher while holding it down even though it is in the locked state, the lock will be released and the pusher will be able to move down. As a result, a problem occurs in which the content liquid is discharged.

The present invention has been developed to solve the above-mentioned problem.In an air pot that has a structure in which the downward movement of the pusher is restricted by rotating the pusher in conjunction with a lock lever, the pusher is in a locked state. To provide a presser body safety device for an air pot which prevents the presser body from rotating and prevents it from moving downward even if a force is applied to rotate the presser body while pressing the presser body. purpose.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are examples of the present invention.

In Figures 2 and 3, 1 is a metal body housing a medium bottle 2 inside, 3 is a metal shoulder body placed and fixed on the upper end of the body 1, and 4 is a bottle opening of the medium bottle 2. The inner stopper 5 is fitted into the body 1, and 5 is a lid pivotally attached to the upper end of the body 1.

The lid body 5 has an air pump 6 built therein, a push body 20 for pressing the air pump 6 is provided at the top, a hook lever 7 is provided at the front end, and a lock lever 26 is provided at the rear end. ing.

As shown in FIGS. 4 and 5, the lid body 5 has a double structure consisting of an inner tube 8 and an outer tube 9 that hang down from the top surface. A pivot joint 10 is formed at the rear end of the outer tube 9, and A beak-shaped protrusion 11 is formed in the holder.

At the lower end of the inner cylinder 8, there is a 3 that restricts the position of the upper surface of the air pump 6.
A protrusion 13 for feeling is provided at the rear end position of the outer peripheral surface of the inner cylinder 8.

Further, on the inner surface of the outer cylinder 9, a claw 15 for attaching the lower plate 14 from below, a vertical rib 16, and a lock lever 26 are provided.
A fitting claw 17 for attachment is provided.

Furthermore, a window hole 18 for protruding the lock lever 26 and an exposure hole 19 for the hook lever 7 are provided at the upper end of the lid body 5.

As shown in FIGS. 6 and 7, the pusher 20 has a cross-sectional-shaped pusher 21 in the center, and its lower end protrudes outward. Three elongated holes 22 to be fitted are formed, and four notches 23, one recess 24, and one large relief part 25 are provided at the outer peripheral end. Four grooves 20a are provided in the vicinity of the notch 23 on the lower surface.

The cutout portion 23 is to slidably engage the rib 16 of the lid body 5, and the relief portion 25 is to prevent contact with the hook lever 7.

Further, the groove 20a has the function of fitting the upper end 16a of the rib 16 to prevent rotation of the pushing body 20.

As shown in FIGS. 8 and 9, the lock lever 26 has a knob 27 at its upper end, and has a protrusion 28 a that can be engaged with the protrusion 13 and a steady rest sliding protrusion 28 b on its inner surface.
In addition, an engagement piece 29 is provided protruding from the lower end.

Next, the method of assembling the pusher 20 and the lock lever 26 into the lid 5 will be explained. First, the lock lever 26 is forcibly fitted between the inner cylinder 8 and the outer cylinder 9 from below the lid 5. , the lower surface of the lock lever 26 is supported by the fitting claw 17, and the knob portion 27 of the lock lever 26 is made to protrude from the window hole 18 of the lid body 5.

In this way, the lock lever 26 is attached to the lid 5 so as to be movable in the circumferential direction by a stroke corresponding to the size of the window hole 18.
When inserted inside, the hanging piece 12 of the lid 5 fits into the elongated hole 22 of the pusher 20, and the notch 23 on the outer periphery of the pusher 20 and the lid 5
The recess 2 on the outer periphery of the pusher body 20 engages with the rib 16 of the
4 and two engaging pieces of the lock lever 26 engage with each other.

Thereafter, the air pump 6 may be housed within the lid body 5.

In the lid body 5 assembled as described above, the push body 20 is normally
is pushed up by the return spring of the air pump 6, and the pressing part 2
1 is flush with the top surface of the lid 5, and the notch 23 of the pusher 20 is located slightly above the rib 16 of the lid 5.

Therefore, if the pusher 20 is pressed in this state, the pusher 2
0 moves downward while engaging with the rib 16 and the retaining piece 29 of the lock lever 26, compressing the air pump 6 to supply air into the medium bottle 2, and pouring out the contents.

Now, when the lock lever 26 is operated in the direction of the arrow in FIG. deviate from

Even if the pusher 20 is pressed in this state, the notch 23 and the rib 1
6 do not correspond to each other, the pushing body 20 does not move downward, and the liquid inside the medium bottle 2 is not poured out.

Therefore, even if the pusher body 20 is pressed, the content liquid will not be poured out and it is safe.

Furthermore, if you accidentally rotate the Shintai with your palm or the like while pressing the pressing part 21 in the locked state, the lower surface of the outer peripheral end of the pressing part 20 will slide on the upper end 16a of the rib 16, and the notch 2
3 may return above the rib 16, and there is a risk that the pushing body 20 may move downward.

In such a case, before the notch 23 returns to above the rib 16, the upper end 16a of the rib 16 fits into the groove 20a provided on the lower surface of the outer peripheral end of the pusher. This prevents the lock from being accidentally released.

Note that since the pushing body 20 is constantly pushed up by the upward return force of the air pump 6, when the lock lever 26 is operated, the concave groove 20a and the upper end 16a of the rib 16
The two do not fit together, and there is no problem in operating the lock lever 26.

In the above embodiment, the pusher body 20 and the lock lever 26 are separate bodies, and the lock lever 26 is configured to engage the pusher body 20 in a vertically movable manner. -26 may be constructed as an integrally formed piece.

As is clear from the above description, according to the present invention, the vertical rib provided on the lid body engages with the notch of the push body to guide the push body in a vertically movable manner, and the outer circumference of the push body A groove into which the upper end of the rib can fit is provided on the lower surface of the end, so when the pusher is in the locked state, the upper end of the rib will not fit into the groove even if the pusher is rotated while holding down the suppressing part. It fits and prevents rotation, so there is no problem of the lock being accidentally released and the liquid inside being discharged.
