Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called Ramune bottle for opening and removing a cap, and a Ramune bottle equipped with this opening tool.

[0002]

2. Description of the Related Art A so-called Ramune bottle cap is known in which a spout is formed in a central portion, a sealing ball is provided on the back side of the spout, and the sealing ball is pushed down to open the cap. Since such a cap is firmly fixed to the bottle, it cannot be easily removed from the bottle after drinking the carbonated beverage as the content. However, if a weakening groove is provided from the vicinity of the spout of the cap toward the outer peripheral direction,
After drinking, you can remove the cap from the bottle by spreading the spout to break the cap through the weakening groove. In this way, if the cap can be easily removed from the bottle, the bottle can be used as a returnable bottle, or the bottle and the cap can be separated and recycled to make effective use of resources.

The cap 12 shown in FIGS. 5 and 6 is an example of such a cap. The cap 12 includes an outer cylindrical body 13, an inner cylindrical body 14 and a sealed ball 15. The outer cylinder 13 is made of a hard plastic such as polypropylene and has a substantially dome-shaped overall shape. The inner peripheral surface has an engaging portion 18 that engages with a protrusion 21 formed on the outer periphery of the mouth of the bottle 11. A spout 16 is formed at the center of the top. The peripheral wall 19 of the spout 16 is formed downward from the periphery of the spout, and a ridge 20 for connecting the inner cylindrical body 14 is formed on the outer periphery of the lower end thereof. On the inner surface of the outer cylindrical body 13, the weakening groove 1 is formed from the vicinity of the spout 16 toward the outer side.
Two 7 are provided. The weakening groove 17 is a groove having a V-shaped cross section, and this portion is easily broken.

The inner cylinder 14 having a generally cylindrical shape is made of soft polyethylene, and the outer peripheral surface thereof contacts the inner surface of the mouth of the bottle 11 to seal the contents. A glass sealing ring 15 is wrapped around the inner peripheral portion of the inner cylindrical body 14. The sealing ball 15 is pressed against the inner peripheral portion of the inner cylindrical body 14 by the force of pushing it up by the internal pressure of the carbonated beverage as the content, and the airtightness is maintained. A ridge 24 formed inside the upper part of the inner cylindrical body 14
Is engaged with the protrusion 20 of the outer tubular body 13, so that the inner tubular body 14
Are connected to the outer cylindrical body 13. However, the coupling mode of the outer cylinder body and the inner cylinder body is not limited to this example, and various modes are possible.

As an example of such a cap opening tool, a cap opening tool 25 shown in FIG. 7 can be considered. Opener 25
Is a cylindrical or rod-shaped projection 27 integrally formed on one side (lower surface) of the disk-shaped flange 26. The tip side of the protrusion 27 is the spout 16 of the cap 12.
A small diameter portion 28 having a smaller diameter and a large diameter portion 29 having a larger diameter than the spout are formed on the base end side. A taper between the large diameter portion 29 and the small diameter portion 28 is formed such that the base end side becomes thicker. This is because the large diameter portion 29 can be smoothly pushed into the spout 16 when the cap is broken. When opening the stopper, the protrusion 27 of the stopper 25 is pushed down to the small diameter portion 28 into the spout of the cap, and the sealed ball is pushed down. After drinking, the protrusion 27 of the stopper 25 is pushed up to the large diameter portion 29 into the spout of the cap. . Large diameter part 29
Since the outer diameter of is larger than the inner diameter of the spout 16, the spout 16 is expanded by this, and the fracture starts from the weakening groove 17, and the outer cylinder 13 is completely destroyed at the end. After destroying the outer cylinder body 13 in this way, the inner cylinder body 14 and the sealing ball 15 are removed, so that the cap 12 is completely closed.
Removed from.

The stopper 25 is, for example, as shown in FIG.
The cylindrical spacer 30 is inserted into the protrusion 27, placed on the top of the cap 12, wrapped with a film 31, and attached to a Ramune bottle for sale.

[0007]

In the case of opening with the above-mentioned opening tool 25, it is possible to push down to the small diameter portion 28 into the spout 16 by opening with a suitable force. However, if the pushing force is too strong, the large diameter portion 29 of the protruding portion 28 is pushed in when the cap is opened, and the cap is destroyed.

In addition, when the stopper 25 is attached to a Ramune bottle as shown in FIG. 8, there is a problem that the protrusion 27 becomes long and bulky.

According to the present invention, there is provided a cap opening tool which is capable of both cap opening and cap removal without fear of breaking the cap when the cap is opened and which is not bulky when mounted on a Ramune bottle. That is the issue.

[0010]

Means for Solving the Problems The present invention has a spout formed at the center and a sealing ball on the back side thereof for opening, and by pressing down the sealing ball, the stopper is opened, and after completion of drinking, What is claimed is: 1. A cap opening tool for a carbonated beverage bottle equipped with a cap capable of breaking the cap by opening the spout and removing it from the bottle, wherein one side of the flange portion 4 has a diameter larger than the diameter of the spout. A cap 2 having a projection 5 having a diameter smaller than that of the spout and a hole 10 through which the projection 5 can pass are formed, and a flange 6 having a diameter larger than the diameter of the spout. On one surface thereof, there is provided a removing member 3 in which a cylindrical portion 7 having an axially formed slit 8 is projected around the hole 10, and the protruding portion 5 of the opening body 2 is used as the spout. The sealed body is pushed down to open the stopper, After inserting the tubular portion 7 to the spout, by pushing the protruding portion 5 of the cap removal member 2 in the cylindrical portion 7 from the bore 10, enlarged diameter of the cylindrical portion 7,
A cap opening tool for carbonated beverage bottles characterized by breaking the cap.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the drawings showing the embodiments. FIG. 1 shows a stopper 1 according to an embodiment.
2 is a perspective view of a disassembled state, FIG. 2 is a side view of the cap 12 with the cap 1 mounted on the top of the cap 12, FIG. 3 is an explanatory view of opening the cap with the cap 2, and FIG. 4 is a cap of the cap 1. It is explanatory drawing which destroys.

The opener 1 shown in FIGS. 1 to 4 comprises a plastic opener 2 and a remover 3. The opening body 2 is
The protrusion 5 having a diameter smaller than that of the spout 16 is provided on one surface of the flange 4 having a diameter larger than the inner diameter of the spout 16 of the cap 12. The removing body 3 is formed by projecting a cylindrical portion 7 on one surface of a flange portion 6 having a diameter larger than that of the spout 16. In the flange part 7,
Inside the cylindrical portion 7, a hole 10 through which the protrusion 5 can pass is formed. The cylindrical portion 7 is formed with four slits 8 in the axial direction, and the diameter thereof can be reduced or expanded. The inner diameter of the tubular portion 7 is slightly larger than the outer diameter of the protruding portion 5 of the opening body 2. Also, the tubular portion 7
Is formed thicker than the tip portion, and an inclined surface 9 is formed on the outer peripheral surface from the tip portion to the middle portion.
The maximum outer diameter of the tubular portion 7 is larger than the inner diameter of the spout 16.

As shown in FIG. 1, in the opening body 2 and the removing body 3, the protruding portion 5 and the cylindrical portion 7 are opposed to each other, and the protruding portion 5 is formed in the cylindrical portion 7 as shown in FIG. Can be inserted and integrated. Then, it can be mounted on the top of the cap 12 mounted on the bottle 11 and fixed on the top of the cap 12 by an appropriate means such as a film 30 to be mounted. In this case, since the protrusion 5 is inserted into the tubular portion 7, the cap opening tool mounted on the cap is not bulky. In addition, in the case of this embodiment, the inner diameter of the tubular portion 7 is slightly larger than the outer diameter of the projection 5 of the opening body 2, but the diameter of the tubular portion 7 should be enlarged by the slit 8. Therefore, it is not always necessary to make the diameter larger than the outer diameter of the protrusion 5.

When opening the stopper, the film 30 is peeled off from the state shown in FIG. 2 and the stopper 1 is taken out to separate the stopper 2 and the remover 3. Then, as shown in FIG. 3, the projecting portion 5 of the unsealing body 2 is faced downward, the spout 16 is inserted, and the flange portion 4 is inserted.
The protrusion 5 is pushed into the spout 16 by hitting or pressing it, and the sealing ball 15 is dropped. Since the outer diameter of the protrusion 5 is smaller than the inner diameter of the spout 16, there is no possibility of breaking the cap 12.

When removing the cap 12, first, as shown in the upper side of FIG. 4, the tubular portion 7 of the removing body 3 is inserted into the spout 16 of the cap 12. Since the maximum diameter of the tubular body 7 is larger than the inner diameter of the spout 16, the action of the slit 8 reduces the diameter of the tubular portion 7. Then, the protrusion 5 of the opening body 2 is pushed into the hole 10 and the cylindrical portion 7 from above the flange portion 6. Then, the once reduced diameter of the tubular portion 7 is expanded by the protrusion 5. Since the maximum diameter of the tubular portion 7 becomes larger than the inner diameter of the spout 16 of the cap 12 in the state where the protrusion 5 is inserted, the spout 16 is widened, as shown in FIG.
As shown on the lower side, the outer cylinder 13 is broken by the action of the weakening groove 17. In the present embodiment, the maximum diameter of the tubular portion 7 is originally larger than the inner diameter of the spout 16, but it is not always necessary. The point is that the maximum diameter of the tubular portion when the protrusion 5 is inserted is It should be larger than the inner diameter of the spout. The sloped surface 9 of the tubular portion 7 may be provided inside, or a protrusion or a ridge may be provided instead of the sloped surface. However, when the slope is provided, the opening body can be easily pushed in.

In the present invention, since the cap is not destroyed by merely pushing the removing body 3 into the spout, even when the user tries to open the cap and mistakenly uses the removing body 3 as the cap body 2, the cap is removed. Is never destroyed.

It is needless to say that the present invention can be modified without departing from the scope of the claims.

[0018]

The cap of the present invention has no risk of breaking the cap when the cap is opened, and moreover, not only the cap can be opened but also the cap can be easily removed. Also,
It can be made compact by combining the opener and the remover, so it can be smartly attached to the top of the cap and will not get in the way.
