Abstract

(57) [Summary] [Purpose] When inserting a push button having a retaining protrusion on the outer peripheral surface of the lower end into a guide hole of a stopper cover from the outside, the retaining protrusion does not become an obstacle to insertion. The objective is to ensure that the projection prevents the device from coming off. [Structure] The upper end of a vertical shaft 24 is inserted into the lower end of the push button 21, and when a force in the pulling direction is applied to the push button 21, the vertical shaft 24 limits reduction in the diameter of the lower end.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to an inner stopper opening/closing device for liquid containers such as hand pots. It is.

0002

[Conventional technology]

The inner stopper of the liquid container is screwed into the opening of the container shoulder body, thereby sealing the inner container. When discharging the liquid in the inner container, press the push button of the valve provided on the inner stopper. The liquid is discharged from the beak of the shoulder body by opening it by operation and tilting the entire container. BACKGROUND ART A device for opening and closing an inner cap of a liquid container that allows the liquid to be discharged has been widely known.

0003 Also, in this case, the first press of the push button opens the valve. The valve is held open, and the second press of the push button closes the valve. The valve opening/closing mechanism is a so-called push-push mechanism that is different from the conventional handle. Commonly used in dopots (for example, see Utility Model Publication No. 58-30023) ).

0004 In an inner stopper opening/closing device that uses such a push-push mechanism, the push Insert the push button into the guide hole of the inner plug cover so that it can move up and down, and then The lower end is configured to engage with a valve opening/closing mechanism.

[0005] In this case, the push button is cylindrical so that its outer diameter matches the inner diameter of the guide hole. Further, an engaging protrusion for preventing the push button from being removed is provided on the outer peripheral surface of the push button. P Since the push button is provided with the engaging protrusion as described above, the push button Assembly of the plug is done by inserting it into the guide hole from inside the stopper cover. Ru.

[0006]

[Problem that the idea aims to solve] The push button is inserted into the guide hole from inside the bung cover as described above, and then The head of the push button is exposed on the top surface of the stopper cover, so the head of the push button The outer diameter of the part is limited to the inner diameter of the guide hole and cannot be larger than that.

[0007] However, from the viewpoint of usability and design, the head of the push button should be placed in the guide hole. If a request arises for the inner diameter of the push button to be larger than the It must be inserted into the guide hole from the outside of the stopper cover. Then push The protrusion provided on the outer circumferential surface of the button to prevent it from coming off poses a problem.

[0008] If the protrusion is made smaller, it will be easier to pass the push button through the guide hole. However, the retaining effect will be insufficient. On the other hand, if this protrusion is made larger, the retaining effect will be sufficient. Even so, it becomes difficult to pass it through the guide hole.

[0009] Therefore, this idea is to make the head of the push button larger than the inner diameter of the guide hole. It is easy to pass it through the guide hole of the stopper cover when it is removed, and it has a reliable action to prevent it from coming out. The challenge is to make sure that

[Means to solve the problem]

In order to solve the above problem, this idea was developed to provide a guide for the stopper cover that is integrated with the inner stopper. Insert the push button into the hole so that it can move up and down, and insert the valve provided in the inner plug into the push button. Opening the inner cap of a liquid container that opens and closes via a valve opening/closing mechanism operated by a button. In the closing device, the push button is formed into a cylindrical shape with an open bottom end, and the push button A retaining protrusion of the required height is provided on the outer peripheral surface of the lower part of the button, and the engaging stepped part of the protrusion is The upper end of the vertical shaft engaged with the valve opening/closing mechanism is inserted into the pulley. The button is inserted into the bottom end of the button without any gap or with the required gap. It is something.

[0011]

[Effect]

The above-mentioned retaining protrusion has a fitting gap for the guide hole of the push button. Due to the elastic deformation of the material, it can easily pass through the guide hole, and it can also easily pass through the guide hole's engagement step. It is formed at a height that can be engaged and prevented from coming off. In addition, the vertical axis and push button inner diameter There is no gap between the push button and the push button. When the lower end of the button is reduced, the outer diameter surface of the vertical shaft comes into contact with the inner diameter surface of the push button. , is set so that there is a gap that prevents reduction beyond a certain level.

0012 For this reason, the push button is relatively small from the outside of the bung cover to its guide hole. Penetrated by resistance. Also, a force in the direction of pulling out may be applied to the push button, causing the Even if the end shrinks, its inner diameter surface hits the outer diameter surface of the vertical shaft, so the diameter will not shrink beyond a certain level. This prevents the product from coming off.

【Example】

The liquid container of the embodiment is a hand pot as shown in FIG. This hand As shown in Fig. 2, the dopot has a shoulder body 2 having a truncated conical outer shape at the upper end of the body 1. At the same time, attach the bottom body 3 to the lower end and open the mouth of the vacuum double bottle 4 stored inside. It is pressed against the opening 5 of the shoulder body 2 via a packing 6. Splashes on the inner diameter surface of the opening 5 A cross hole 8 is formed in the shoulder body 2, and a horizontal hole 8 passing through the opening 5 laterally. It communicates with the inside of the brush 9.

[0014] A plug packing 11 is attached to the outer diameter surface of the inner plug 10 that is screwed into the threaded part 7. (see FIG. 3) and press it against the seal step 12 on the inner diameter surface of the opening 5. to close the opening 5.

[0015] Also, inside the inner stopper 10, the vacuum double bottle 4 and the beak 9 are communicated with each other. A liquid passage 13 is formed, and a valve 14 that opens and closes the opening on the vacuum double bottle 4 side is movable up and down. mounted on. This valve 14 is urged upward by a spring 15 and pushed against the valve seat 16. Assigned.

[0016] At the top of the inner stopper 10, a stopper cover 17 having the same taper as the shoulder body 2 is strongly attached. They are integrated by tight fitting. The lower end of this plug cover 17 matches the upper end of the shoulder body 2, Both form a conical outer shape. from the upper end of this stopper cover 17 to the upper end of this plug cover 17. A guide hole 18 is formed by a cylindrical portion that hangs downward. The guide hole 1 An engagement step 19 is formed on the inner diameter surface of 8, and the diameter becomes smaller above the engagement step 19. ing.

[0017] The push button 21 has an upper half shaped like an inverted triangular pyramid and a lower half shaped like a cylinder. be done. The cylindrical portion is inserted into the guide hole 18 so as to be vertically movable. This push button Several vertical slits 22 are provided at the bottom of the tongue 21 (see Figure 4). A retaining protrusion 23 is formed between the lits 22 and protrudes outward.

[0018] Note that if a highly elastic material is used, a thin film may be formed in the slit 22 or Alternatively, the slit 22 may be omitted.

[0019] The retaining protrusion 23 engages with the engagement stepped portion 19 of the guide hole 18 and presses the push button 2. 1 to prevent it from falling off. Further, the lower surface of each retaining protrusion 23 is tapered.

[0020] The protrusion height of the retaining protrusion 23 is such that the lower tapered surface is above the guide hole 18. When pressed against the edge and applying the required force, the bottom of the push button 21 The end portion is set at such a height that it shrinks due to elastic deformation of the material and can pass through the guide hole 18. determined.

[0021] As mentioned above, there is a certain limit on the height of the retaining protrusion 23, so do not make it too high. Therefore, simply engaging this with the engagement stepped portion 19 will not work to prevent it from coming off. is incomplete. For this reason, the upper end of the vertical shaft 24 is located inside the lower end of the push button 21. The section is inserted.

[0022] There is no gap between the outer diameter surface of the vertical shaft 24 and the inner diameter surface of the push button 21, or Even if the lower end of the push button 21 is reduced, the retaining protrusion 23 is removed from the engagement stepped portion 19. Before it comes off, the inner diameter surface of the push button 21 hits the outer diameter surface of the vertical shaft 24, and then It is set so that there is a gap that can prevent further reduction. The upper end of the vertical axis 24 is It is engaged with the lower end of a rib 25 provided on the inner diameter surface of the push button 21.

[0023] The opening/closing mechanism 26 of the valve 14 includes a cylindrical mechanism shaft 27 fixed to the inner stopper 10 and the valve 14. It is composed of a rotating shaft 28 fixed to the upper end of the holder and the above-mentioned vertical shaft 24. these The members constitute a well-known push-push mechanism (see the above-mentioned utility model publication). .

[0024] It should be noted that the outer diameter surface of the push button 21 is provided with the upper part of the stopper cover 17 when the valve is closed. A shallow groove 29 that serves as a mark is formed in the higher part than the end, and when the groove 29 is visible, the valve closes. The valve is in the open state when it enters the guide hole 18 and is not visible from the outside. Show that.

[0025] A conspicuously colored member may be fitted into this groove 29, or a thin tape may be used instead of the groove 29. You may also paste a circle or draw a colored line.

[0026] Further, on the outer surface of the stopper cover 17, vertical ribs 31 are arranged at fine intervals over the entire circumference. (see Figure 4) to prevent your hand from slipping when removing or tightening the inner stopper 10. I'm trying to prevent it.

[0027] The hand pot of the example is as described above, and its inner stopper opening/closing device was assembled. When installing, force the push button 21 into the guide hole 18 from the outside of the stopper cover 17. 2, engage the retaining protrusion 23 with the engagement step 19 of the guide hole 18, and then Insert the upper end of the vertical shaft 24 of the rear opening/closing mechanism 26 into the lower end of the push button 21 do.

[0028] The inner stopper opening/closing device assembled in this way is operated by the push-push mechanism. Therefore, the valve is opened when the push button 21 is pressed the first time, and the valve is opened when the push button 21 is pressed the second time. The valve is closed by operation.

[0029] In addition, when pouring liquid directly into or out of the vacuum double bottle 4, use the stopper cover 17. Rotate the part and remove it together with the inner stopper 10.

[0030]

[Effect of the idea]

As mentioned above, the inner stopper opening/closing device of this invention has a vertical axis at the bottom of the push button. By inserting the upper end, the protrusion that prevents the push button from coming out is relatively small. This makes it easier to insert the button into the guide hole. Since the diameter reduction is limited, there is an effect that it is possible to securely prevent it from coming off. Therefore, Even if the head of the push button has a larger diameter than the inner diameter of the guide hole, assembly will be difficult. It does not interfere with the operation or retaining function.
