【Example】

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a sectional view showing an example of a sealed stopper structure of a carbonated beverage bottle of the present invention, FIG. 2 is a perspective view showing an example of a packing member, FIG. 3 is a longitudinal sectional view thereof, FIG. 4 is a bottom view thereof, and FIG. FIG. 6 is a vertical cross-sectional view showing another example of the packing member, FIG. 6 is a bottom view thereof, FIG. 7 is a cross-sectional view showing an example of a cylindrical body, and FIG. 8 is a state in which the bottle is upside down after releasing the tight fitting state of the spherical body. FIG.

As shown in FIG. 1, the sealed stopper structure of a carbonated beverage bottle of the present invention comprises a packing member 20 and a spout member 30, and a spherical body 15 is attached to a mouth portion 11 of a bottle body 10 made of glass or the like. The bottle body 10 is fitted while being held and surely seals the bottle body 10.

As will be better understood from FIGS. 2 and 3, the packing member 20 is composed of an adhered portion 21 and a tubular portion 23, and is formed of an elastic material such as rubber. The adhered portion 21 is composed of an annular flange surface 27 extending outward from an upper end 22 of a cylinder portion 23 described below, and covers the mouth end 12 of the bottle main body 10 along an edge 28 thereof. A downward projecting portion 24 is formed, and an annular projecting portion 25 is formed on the upper side along the flange surface 27. The cylindrical portion 23 is provided so as to extend downward from the inside 26 of the adhered portion 21, and elastically holds the spherical body 15 in the mouth portion 11.

In the embodiment shown in FIG. 3, tapered notches 29 are provided at the lower end of the tubular portion 23 of the packing member 20 at three locations as shown in FIG. Thus, in the case where the notch 29 is provided at the lower end of the packing member, as shown in the right half of FIG. 8, after the spherical body is released from the close fitting state, that is, after the single use, To provide a reliable one-way bottle structure that is difficult to reuse due to air leakage even if you try to refill the carbonated beverage with a content and invert the bottle and re-seal with a spherical body. You can

5 and 6 show another example of the packing member. In this packing member 20A, the notch 29A for prohibiting reuse is formed in a groove shape. The operation of the notch 29A is also similar to the above as shown in the left half of FIG.

Next, as shown in FIG. 7, the spout member 30 is composed of a tubular main body 31 formed of resin or rubber, and is fitted into the packing member 20 to be integrated with the mouth portion 11. And the packing member 20 is fixed to the bottle body 10.

The tubular body 31 has an upper portion 34 curved inward to form a spout 32, and a protrusion 35 provided inside the outer peripheral portion 33 of the tubular body 31. The protrusion 35 engages with the groove 14 formed on the outer periphery 13 of the mouth of the bottle body 10 to fix the spout member 30 to the bottle body 10.

An annular groove 37 and a protrusion 38 adjacent to the annular groove 37 are formed on the upper lower surface 36 of the cylindrical body 31 as shown in the figure. The annular groove portion 37 is fitted into the packing member 20 by press-fitting the annular protruding portion 25, and the protruding portion 38 contacts the tip 12 of the bottle body 10 via the flange surface 27 of the packing member 20. The bottle main body 10 is sealed by contact.

[0016]

[Effect of the device]

 As shown and described above, according to the sealed structure of the carbonated beverage bottle of the present invention, the spout member provided with the packing member elastically holding the spherical body is simply attached to the mouth portion of the carbonated beverage glass bottle. The bottle body can be surely sealed. Therefore, the complicated process for forming the tight plug with the spherical body, which has been conventionally performed, is not required, and the molding process is simplified, the working efficiency is significantly improved, and the manufacturing cost is reduced.

Further, as described in the embodiment, in the case where the packing member is provided with the notch at the lower end of the cylindrical portion, the spherical body is re-inserted after the close fitting state of the spherical body is released, that is, after being used once. It is possible to provide a reliable one-way bottle structure that disables sealing and is difficult to reuse, and ensures the safety of consumers who use this carbonated beverage bottle.
