[0009]

The present invention will be described in detail below with reference to the accompanying drawings. 1 to 4 show a first embodiment of a bottle stopper made of synthetic resin according to the present invention. Bottle stopper 1 of the first embodiment
Has a side face portion 3 and a top face portion 2 as its normal form, and the side face portion 3 is integrally formed with a pulling knob 5 having a hole 4 for inserting a finger and hooking,
A portion 6 where the pulling knob 5 and the side surface portion 3 come into contact with each other is freely bendable, and a protrusion actuating hole 7 is formed at the center of the corresponding contact portion 6 so as to face the protrusion actuating hole 7. A protrusion 8 is provided on the side surface portion 3, but the protrusion 8 protrudes below the side surface portion 3. As shown in FIG. 3, the protruding length L is slightly smaller than the length l of the space portion. It projects long.

A cylindrical stopper 9 is integrally formed inside the upper surface 2 of the bottle stopper 1, and a ring jaw 10 is provided inside the cylindrical stopper 9. A reinforcing ring 11 made of a material stronger than the stopper is fitted therein, and a pressure adjusting groove 12 is formed on the outside of the cylindrical stopper 9 facing the projection 8 of the side surface portion 3. Has been done. Then, as shown in FIGS. 3 and 4, a circular insertion groove 13 into which the bottle mouth of the bottle A is inserted is provided between the inside of the side surface portion 3 and the plug body 9.
And a locking jaw 14 for locking the outside of the bottle mouth is formed.
An arcuate cutout portion 15 is formed on the inside of the upper surface portion 2, and the cutout portion 15 leaves an uncutout portion 16 on the opposite side of the pulling knob 5, and the opposite side of the uncutout portion 16 is formed. On the side surface part 3 at a position that is vertically aligned with both side surfaces of the pull knob 5.
A side surface cutout 17 is formed along the lower side of the side surface, and the side surface cutout 17 is in contact with both side surfaces of the pulling knob 5.

Further, the cutout portion 15 is formed by providing a cutting groove from the inside of the insertion groove 13 toward the upper surface portion 2 as shown in FIG. 4, and the side cutout portion 17 is formed. On the contrary, it is formed by providing a cutting groove from the outer side to the inner side of the side surface portion. The bottle cap 1 made of synthetic resin thus configured is capped on the bottle A in a state as shown in FIGS. 1 and 5, but when capped, it is placed on the bottle mouth of the bottle A. When it is positioned and the bottle stopper is pushed with momentary force, the stopper 9 part is inserted inside the bottle A and adheres tightly to the bottle mouth. The inner locking jaw 14 is caught on the outer locking jaw of the bottle A and never comes off or comes off.

When capped in this manner, the bottle stopper 1 is stretchable and thus is instantly expanded and fitted into the bottle mouth without damaging the cutout portion 15, the side cutout portion 17 or the like. . All such steps are performed by currently used automated mechanical equipment. Firstly, as shown in FIG. 5, the bottle stopper made of the synthetic resin of the present invention, which is capped on the bottle A, has the pull knob 5 pressed downward by the continuous operation of the mechanical device. The pulling knob 5 is aligned with the side surface portion 3 of the bottle stopper, but at this time, the projection actuating hole 7 formed in the pulling knob 5 forcibly presses and bends the projection 8 formed in the side surface portion 3, and then Since the length L of the protrusion 8 itself is slightly longer than the length l of the protrusion operating hole 7,
As shown in, the inner wall surface 7a of the projection operating hole 7 and the lower side surface 8a of the projection 8 are in contact with each other, and the pull knob cannot return to the original position, so that the side surface of the bottle stopper 1 is vertically aligned. Will be maintained. If the length of the protrusion 8 is made a little longer, the pull knob will come into closer contact with the bottle, as shown in FIG.

The bottle cap 1 made of synthetic resin of the present invention, which is capped on the bottle in this way, is firmly attached to the bottle mouth by the reinforcing ring 11 into which the plug 9 is inserted. The bottle mouth is inserted into the insertion groove 13 of the bottle stopper 1. Locking jaw of bottle stopper 1
14 is hooked to the outside of the bottle mouth, and when used in carbonated beverage bottles, it provides a perfect seal, similar to using existing metal bottle stoppers.

8 to 11 show the operation of pulling out the synthetic resin bottle stopper 1 of the present invention from the bottle. That is, when trying to pull out the bottle stopper 1 to drink the contents, first insert a finger into the hole 4 of the pulling knob 5 and pull the pulling knob 5 upward, and then the projection operating hole of the pulling knob 5 is pulled. 7 is in the state shown in FIG. 5 while pushing the protrusion 8 lightly, and in this state, when the pulling knob is continuously pulled upward, the cutout portion 17 formed on the side surface portion 3 of the bottle stopper is cut off and the protrusion 7 of FIG. As shown in FIG. 9, the side portion 3 is still attached to the periphery of the bottle mouth when the pulling is further performed, and the cutout portion 15 formed on the upper surface portion 2 of the bottle stopper is cut off as shown in FIG. The body 9 part comes out of the bottle. At this time, when the cutout portion 15 is completely cut off to reach the non-cutout portion 16, the stopper 9 comes out completely from the bottle mouth,
When it is continuously pulled, even the side surface portion 3 can be completely pulled out from the bottle as shown in FIG. In this way, the form of the bottle stopper 1 completely removed from the bottle is that the cutout portion 15 and the side cutout portion 17 are completely cut out as shown in FIG. 11 and are connected to each other only at the uncut portion 16. The side surface portion 3 has a form in which one side is completely cut.

On the other hand, the pressure adjusting groove 12 (FIG. 2) formed in the stopper 9 in this embodiment prevents the contents from overflowing in the case of a carbonated beverage when the bottle stopper 1 is pulled out. That is, in the case of carbonated drinks, if the contents are shaken, it will overflow if the cap is removed, but the pressure adjustment groove will be in the middle of opening the cap.
As soon as 12 is exposed at the bottle mouth, the internal pressure is gradually discharged through it, preventing the contents from overflowing.

The reinforcing ring 11 fitted in the inside of the stopper 9 is made of a material having higher strength than the material of the stopper 9, and the portion of the stopper 9 firmly adheres to the inner wall of the bottle mouth. To do so. That is, in order to increase the tightness of all glass bottles, the outer diameter of the stopper 9 may be made larger than the diameter of the bottle mouth, or the size may be such that the inner diameters of the stopper and the bottle are precisely brought into close contact with each other. However, in the case of the former, when the cap of the bottle is capped, a fine crack is generated in the bottle mouth part,
In the latter case, the inner diameter of the bottle mouth will be small, but there will be slight differences, no matter how much precision is attempted in the manufacturing process of the bottle.

Therefore, in the present invention, the above-mentioned problems are solved by using the reinforcing ring 11 which is stronger than the material of the plug 9. Further, in order to obtain a higher sealing effect, the form of the reinforcing ring 11 may be configured as shown in a to e of FIG. That is, as shown in FIG. 13a, it can be manufactured in a form in which the top and bottom are penetrated.
As shown in b), if the double-walled body is formed, the elastic force of the double-walled body itself increases, and the adhesion effect becomes more excellent.

Further, FIG. 13c shows a case in which both sides are rounded inward in a state of penetrating vertically to form a circular groove 11a to enhance elasticity, and FIG. 13d shows an outer periphery in a gear shape 11b. 13e has a notch groove 11c formed on the upper and lower sides to increase the elastic force, so that even if there is a difference in the inner diameter of the bottle mouth, the elasticity of the reinforcing ring allows constant contact. I have to.

On the other hand, in the present invention, the plug 9 itself may be provided with elasticity directly in a technical structure in which the reinforcing ring 11 is not used. That is, FIG. 14 shows a structure in which the space of the plug 9 itself is made slightly thicker and a space 9a is formed therein to give elasticity, and FIG.
b is provided continuously to give elasticity, and FIG. 16 shows a small blade 9c protruding inside the plug body. However, in both cases, the plug body itself has elastic force. By doing so, the same sealing effect as when the reinforcing ring 11 is fitted is obtained.In particular, in the case of FIGS. 14 and 15, if the reinforcing ring 11 is fitted and used as in FIG. It is also possible to obtain an even better sealing effect.

As another structure for enhancing the sealing effect, FIG. 18 shows that a packing 13a is integrally formed on the upper side of the insertion groove 13 with which the upper portion of the groove mouth is in contact in order to enhance the sealing effect of the upper portion of the bottle mouth. is there. In this case, when the upper portion of the bottle mouth is fitted into the insertion groove 13, as shown in FIG. 19, the packing 13a swells due to the pressure and adheres to the upper portion of the bottle mouth, further enhancing the adhesion effect. it can. Also,
As shown in FIGS. 21 and 22, a separate packing 13b made of foamed resin or the like can be fitted on the upper surface of the insertion groove 13, but in this case, the packing 13b entirely covers the upper portion of the bottle mouth. It has the effect of bringing them into close contact.

Then, as shown in FIGS. 20, 21 and 22, a cutout portion 15 formed on the inner upper surface of the insertion groove 13 of the bottle stopper 1 is formed on the upper side surface of the bottle stopper 1. Again, the sealing effect is increased. FIG. 23 shows a cutout portion 15 formed on the bottle stopper 1.
The plug 9 is pulled out better by changing the shape of the above. That is, a complete circular continuous cutout portion 15 is formed without leaving an uncut portion on the upper surface of the bottle stopper 1, and at the same time, a semicircular auxiliary cutout portion 15a is formed inside the cutout portion 15. . In this case, when the pulling knob is pulled to pull out the bottle stopper 1, the cutout portion 17 on the side surface is cut off, and when it is continuously pulled, the auxiliary cutout portion 15a is cut off, but at the place where the auxiliary cutout portion 15a ends. As shown in FIG. 24, the cut-out portion 15b of the pull knob 5 is the plug 9
It becomes vertical to the plug at the position of the center line. When pulling further from this state, the stopper 9 is pulled out vertically without resistance on the side surface. Therefore, the advantage that the upper and lower lengths of the reinforcing ring 11 can be formed to be longer to further enhance the sealing effect, and if this structure is used for a bottle mouth such as a champagne,
Since the internal pressure is released instantaneously, it has the advantage that the contents pour like a fountain.

FIG. 25 shows a structure in which the reinforcing ring 11 is connected to the inside of the stopper on the upper side of the bottle stopper 1, and the reinforcing ring 11 is exposed to the outside. 26 has the advantage that it can be printed with a mark or a quality indication. In FIG. 26, the upper surface of the reinforcing ring 11 is expanded to the same size as the bottle stopper 1, and the inside of the stopper is located above the bottle stopper 1. The expansion portion 11d of the reinforcing ring 11 covers the entire upper surface of the bottle stopper 1 when the bottle stopper 1 is connected to the bottle stopper 1. In this case, since the reinforcing ring 11 itself has high strength, it has an advantage that the bottle stopper 1 will not be damaged even when a strong impact is applied to the upper surface of the bottle stopper 1, and further, the upper surface portion of the reinforcing ring 11 Since a cutoff line 15b is provided on the periphery of the tongue and the cutoff line 15b is cut off when an illegal act is attempted by a driver or the like, the illegal act can be prevented.

27 and 28 are similar to FIG. 25 in that the reinforcing ring 11 is connected to the inside of the stopper on the upper side of the bottle stopper 1, but the structure of the lower surface of the stopper is improved. The sealing effect is further enhanced. In the case of FIG. 27, the stopper 9
The lower side surface is rounded and protruded downward so that it can be used more effectively in a bottle to which carbon dioxide pressure is strongly applied. That is, the lower side surface of the stopper 9 is spread out by the carbon dioxide pressure inside the bottle in a state of a broken line, and the side surface portion 9d is even more closely attached to the inner surface of the bottle.

In FIG. 28, the bottom surface of the stopper 9 is protruded upward and a ventilation hole 11d is formed on the upper surface of the reinforcing ring so as to be suitable for a vacuum bottle. In this case, when the inside of the bottle A is in a vacuum state, the lower side surface of the stopper 9 spreads in the state of a broken line and the side surface portion 9d adheres to the inner surface, so that the sealing effect can be further increased. The external pressure of the air that has flowed into the reinforcing ring through 11d makes it easier to spread the bottom surface of the plug.

29 to 32 show a second embodiment of the synthetic resin bottle stopper according to the present invention. Drawing regarding the second embodiment
29 and FIG. 30 show the anti-counterfeit belt 19 around the lower side of the side portion 3.
The cutout portion 20 is formed between the side surface portion 3 and the forgery prevention zone 19, and the configuration of the other portions is similar to that of the first embodiment. As shown in FIG. 30, the forgery prevention zone 19 is integrally formed when the bottle stopper 1 is illegally pulled out by using the screwdriver 21 or the like, the forgery prevention zone is cut out from the side surface portion 3 and the beverage bottle stopper is removed. Since the consumer can easily confirm whether or not the contents of the bottle A have been forged by indicating that the bottle has been pulled out once, it is possible to further strengthen the sense of trust in the product.

31 and 32, the upper surface 2 of the bottle stopper is formed so as to bulge upward and a large number of elastic pieces 2a are provided on the lower inner surface thereof. in this case,
It is for use in vacuum-type bottles, and when the inside of the bottle is in a vacuum state, the internal pressure decreases, so the protruding part on the upper side of the bottle stopper should be dented downward as shown in Fig. 32. I will end up. If the bottle stopper 1 is illegally pulled out and capped in this state, the degree of vacuum in the bottle is lost and the upper side of the bottle stopper is raised again as shown in Fig. 31. Therefore, it is possible to completely prevent the risk of forgery.

33 to 36 show a third embodiment of the present invention. In this embodiment, as shown in FIGS. 33 and 34, a triangular reinforcing piece is used instead of the reinforcing ring 11 inside the plug 9.
A support piece 24 that integrally forms 23 and that connects the side surface portion 3 and the pull knob 5 is formed integrally at an angle of 45 ° across the space portion 7. A material having higher strength than the material of No. 5 is desirable.

In this embodiment as well, since the support piece 24 supports the plug 9, the same effect as that of the reinforcing ring 11 can be obtained. Such a support piece 24 is as shown in FIG. It is also possible to connect them to each other to form a circular shape.
On the other hand, the support piece 24 can keep the pulling knob 5 parallel to the upper surface portion 2 of the bottle stopper 1 as shown in FIG. 33, or can maintain the pulling knob 5 vertically to the side surface portion 3 as shown in FIG. However, when the pulling knob 5 is pushed downward after the bottle stopper 1 is attached to the bottle A, the support piece 24 is not deformed and both side portions of the projecting operation hole 7 of the pulling knob 5 are bent, so that the supporting piece 24 is bent.
The pulling knob 5 comes into close contact with the bottle as shown in FIG. vice versa,
When the bottle stopper 1 is to be pulled out, it is pulled out in the state shown in FIGS. 33 to 36.

37 to 41 show a fourth embodiment of the present invention. In this embodiment, the forgery prevention band 19 and the pulling knob 5 are integrally formed at the lower end of the side surface portion 3,
