The present invention relates to a vacuum thermos bottle, and more particularly to a vacuum thermos ejection cap configured to be able to pick up the contents without releasing the cap body.

The sealing of vacuum thermos, which keep the liquid contents cool or warm, usually depends on a cap screwed cap.

The cap of this type has been developed in such a way that a separate passage is opened on the body of the cap and a stopper opened and closed with one touch is added because of the inconvenience of having to loosen and tighten it every time the vacuum thermos is used.

The present applicant has disclosed in the Korean Utility Model Registration Application No. 94-18694 with a cap for a vacuum thermos bottle provided with a separate stopper.

The cap disclosed herein includes a structure in which a stopper of one side is interlocked to open when the user presses a button that protrudes slightly in the center, and the button is raised and returned to a certain height when the user presses and closes the stopper again.

However, in the structure as described above, the locking means for retaining the pressed state to restrain the button, especially when opening, and to release the restrained button when the stopper is closed is very complicated assembly productivity is extremely low, The disadvantage that the malfunction rate is relatively high has been found.

An object of the present invention is to provide an injection cap for a vacuum thermos bottle improved in a completely new structure to fundamentally solve the problems found in the above-mentioned Korean Utility Model Registration Application No. 94-18694.

In accordance with the above object, the present invention is that the arm extending to one side of the stopper by the lowering of the button is interlocked to open a separate injection passage and the outer peripheral groove of the locking shaft formed extending to the lower side of the button as described above By engaging and engaging the locking member at the inner circumferential position of the guide hole drilled in the center of the locker, the lowering position of the button is preserved, and the opening of the plug is made. An injection cap for a vacuum thermos bottle is proposed in which the locking axis is released from restraint by a member to close a stopper.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a preferred embodiment of the present invention in an exploded state, in which 2 designates a cap body. A separate pouring passage 4 is opened on one side of the inner peripheral surface of the cap body 2, and the bearing 6 is formed in the shape of a concave groove on the upper end of both walls constituting the pouring passage 4.

The stopper 8 is arranged to be rotated at a predetermined angle by placing the shaft 10 extending in both sides of the stopper 8.

At least one arm 12 extends at one end of the stopper 8 so as to pass near the center of the cap body 2.

On the other hand, the locker 14 is fixed to the inside of the cap body (2). The locker 14 is simply and easily assembled by fitting a plurality of grippers 16 formed at the bottom thereof into holes (not shown) drilled in the inner bottom surface of the cap body 2.

A guide hole 18 is vertically drilled at the center of the rocker 14, and the stopper ball 20 is formed in the middle of the guide hole 18 by being pierced in the axial direction of the locker 14 to communicate with each other. In communication with In this stopper hole 20, the locking member 22 and the ball spring 24 are inserted one by one, and stored and retained by the appropriate stopper 26. As shown in FIG.

The button 28 for opening the stopper 8 extends the locking shaft 30 long downward, and the groove 32 engaged with the locking member 22 described above at a predetermined position on the outer circumferential surface of the locking shaft 30. ) Is formed.

The button 28 also has a flange 34 below its periphery, which is for contacting and interlocking with the arm 12 of the stopper 8. The locking shaft 32 of the button 28 is inserted and assembled into the guide hole 18 of the locker 14. After the assembly of the button 28 is completed, the cover 36 is disposed above the cap body 2. Is fitted with a sheath. The cover 36 has a hole 38 in the center for exposing the upper part of the button 28 to the outside, and an incision 40 for exposing a part of the stopper 8 to the outside, in particular the incision. An inner side of the cover 36 adjacent to 40 is provided with an axis number 42 for supporting the above-mentioned shaft 10 of the stopper 8 from above.

FIG. 2 illustrates an example in which the embodiment of FIG. 1 is applied to a conventional vacuum thermos bottle, and substantially shows the assembly of FIG.

The lower side of the locker 14 is provided with a valve body 46 pressurized with a spring 44, so that the valve seat 48 is always in intimate contact with the valve seat 48 formed on the underside of the cap body 2.

As mentioned above, the structure of the valve body 46 carried by the spring 44 is applied also to the conventional vacuum thermos.

With this configuration, the upper end of the valve body 46 is always in contact with the lower end of the locking shaft 30 of the button 28, so that the injection passage 4 is closed unless the button 28 is pressed. The thermos B is sealed. In this state, the locking member 22 is pushed by the outer periphery of the locking shaft 30 and completely immersed in the inside of the stopper ball 20.

However, when the button 28 is pressed as shown in FIG. 3, the valve body 46 is also pressed together to open the injection passage 4, and at the same time the flange of the button 28 with the arm 12 of the stopper 8. The vacuum thermos B starts to open because it is pressed by 34 and swings the shaft 10 to a point to open.

On the other hand, while the button 28 pressed by the user opens the upper end of the valve body 46 to the lower end of the locking shaft 30, the groove 32 of the locking shaft 30 is connected to the stopper hole 20. When it meets, the locking member 22 is protruded from the stopper ball 20 by the action of the ball spring 24 is engaged with the groove 32 described above. Because of this, the button 28 is restrained and is placed in a floating state in the pressed position, so that the opening of the stopper 8 is maintained, so that the liquid contents of the vacuum thermos B can be taken out.

Next, when the user pushes down the cap 8 and closes it, the arm 12 of the cap 8 pushes up the flange 34 of the button 28 upside down. The locking shaft 30 of the 28 is pushed against the ball spring 24 to push the locking member 22 out of the groove 32 so as to be immersed again into the stopper ball 20 so that the button 28 is released and rises and returns. In this process, the elastic force of the spring 44 that presses the valve body 46 also acts so that the button 28 protruding out of the cover 36 maintains its position so that the thermos B is resealed. do.

On the other hand, the locker 14 is not necessarily provided with a locking member 22 that is supported by the ball spring 24, as in the illustrated embodiment, as shown in FIG. 220 and at the same time the outer peripheral side of the guide hole 18 to be replaced with a locking member 221 having its own elastic force, the locking shaft 30 is inserted corresponding to the locking member 22 The same effect can be obtained when the inner circumferential surface is deformed in a structure in which the locking axis 30 is formed at a predetermined position.

In this case, the locking member 221 of the locking shaft 30 has its own elastic force by the space portion 220, so that the locking member 221 is engaged with the locking groove 222 inside the guide hole 18, or the locking shaft 30 is engaged. While being immersed within the radius of the button 28 is made to rise and fall.

Another configuration suitable for with rocker 14 is illustrated in FIG.

In this modified example, the locking shaft 30 of the button 28 is provided with the groove 32 at a predetermined position on the outer circumferential surface thereof, but the guide hole 18 of the locker 14 is the same as in the above-described embodiment of FIG. ) Has a wedge groove 180 on its outer circumference, and the wedge groove 180 is fitted with a locking piece 223 having a locking member 221 having its own elastic force by the inner space portion 220. It is characterized by a structure that is combined with.

According to the above structure, the locking member 221 of the locking piece 223 is engaged with the groove 32 of the locking axis 30, so that the intended working effect can be obtained and the number of parts becomes one locking piece. The cost savings from the subsequent component reductions and the ease of assembly are gained.

As described above, the present invention inserts and assembles the locking axis of the button into the guide hole of the locker, thereby being restrained at the open position by the locking member, and interlocking with the arm of the stopper with the flange formed on the peripheral surface of the button. Simple but there is an advantage that the opening and closing operation of the stopper is performed reliably.
