Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a replacement plug to be inserted into a bottle mouth of a bottle containing wine, soft drink, and other beverages.

[0002]

[Prior art]

 Conventionally, when removing the cork stopper inserted into the bottle mouth, the cork was pulled from the outside with a cork stopper having a spiral nail on the cork stopper. After eating and drinking, in order to prevent the oxidation of the remaining amount of wine, a cork at the tip was used as a stopper, or a cork that had been pulled out was inserted again into the bottle mouth and capped.

[0003]

[Problems to be solved by the device]

 However, as mentioned above, although the replacement stopper is convenient for wine, etc., if the replacement stopper is repeatedly pulled out from the bottle mouth and repeatedly inserted, the outer surface of the cork will collapse or chip. However, it was often difficult to use as a replacement plug. In addition, cork stoppers on the bottle mouth were often unable to be screwed straight into the spiral nail when the stopper was opened, and the cork was often lost and could not be used again. An object of the present invention is to provide a replacement plug in which the outer peripheral surface of the replacement portion is less likely to be damaged even if the versatility of use increases.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a cork plug comprising a cork-shaped inverted frusto-conical cork and a holding part for holding the plug, and a reinforcing rod fixed to the holding part. The tip was inserted and fixed inside the stopper. Further, the reinforcing rod used for fixing the plug portion and the holding portion may be fixed with a screw.

[0005]

[Action]

 Since the present invention has the above-mentioned configuration, it operates as described below. The plug part made of inverted frustoconical cork has a reinforcing rod built into it and is fixed to the holding part that holds the plug part through this reinforcing rod, so the cork itself when installing or pulling out the replacement plug. It does not bend and acts to prevent damage to the peripheral surface of the plug that is brittle and easily cracked.

Further, the range of reinforcement with the reinforcing rod may be roughly half or less of the plug portion. This is because the plug part of the replacement plug has an inverted frustoconical shape, the side surface is tapered, and the part that contacts the bottle mouth is the upper part of the plug part. This is because if it is reinforced, it acts to prevent the loss of the replacement plug. However, when the reinforcing rod is reinforced roughly over half of the plug, it is natural that the strength can be increased up to the tip of the replacement plug.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway perspective view of a cork stopper according to the present invention, FIG. 2 is a sectional view when a replacement stopper is inserted into a bottle, and FIG. 3 is an exploded perspective view.

In FIGS. 1 and 2, a stopper 1 is made of cork at a portion to be inserted into a bottle mouth, has a shape of an inverted truncated cone, and is tapered as it goes from an upper end surface to a lower end surface. It has a shape. As a result, the bottle mouth is plugged at a relatively slightly upper portion of the tapered shape of the stopper part 1. Further, the insertion hole 2 is formed from the center of the upper end surface of the plug portion 1 toward the lower end to a predetermined depth. The depth of the insertion hole 2 depends on the angle of the taper shape, but the depth of the outer peripheral surface of the plug portion 1 is more than the pressure contact portion with the inner surface of the bottle mouth 6 when inserting the replacement plug (see FIG. 2). . The inner diameter of the insertion hole 2 is the same from the upper surface to the lower surface.

Next, the holding unit will be described. The holding portion 2 is a portion that holds the plug portion 1. The holding portion 2 has a truncated cone shape and is formed such that the lower end surface is somewhat wider than the upper end surface as shown in FIG. In the present embodiment, the holding portion 3 is made of wood, but it may be made of plastic if necessary. Further, the outer shape of the holding portion 3 is not limited to the truncated cone shape, and is not limited to this as long as it is a shape suitable for holding the replacement plug.

As shown in FIG. 3, the bottom surface of the holding portion 3 is formed by opening a generally downward concave mouth so that the upper end surface of the plug portion 1 can be accommodated by about 5 mm. The inner peripheral wall in the concave bottom surface 5 has the same shape as the upper peripheral wall of the plug portion 1, so that the plug portion 1 cannot be easily detached when the plug portion 1 is held. That is, the inner diameter of the upper portion of the concave bottom surface 5 is larger than the inner diameter of the lower portion (on the upper end surface side of the plug portion). Further, the inner diameter of each of the concave bottom surfaces 5 located on the upper peripheral wall of the plug portion 1 is formed to be slightly smaller than the outer diameter of the plug portion.

A reinforcing rod 4 is provided so as to protrude downward from the center of the concave bottom surface. The reinforcing rod 4 has a vertically long cylindrical shape and is inserted and fixed in the insertion hole 2 of the plug portion 1. The reinforcing rod 4 is a core rod for strengthening the strength of the plug portion 1 and fitting the plug portion 1 into the holding portion 3. That is, when the replacement stopper is inserted into the bottle mouth 6, the stopper portion 1 is pressed from the bottle mouth portion, but since the reinforcing rod 4 is inserted in the center, the stopper portion 1 is not deformed more than necessary and does not collapse. . Although the reinforcing rod 4 is made of wood in this embodiment, it can be made of plastic if necessary.

Next, a method of fitting the holding portion and the plug portion will be described. First, the holding portion 3 is held, the reinforcing rod 4 having the concave bottom surface 5 is positioned in the insertion hole 2 of the plug portion 1, and the plug portion 1 is inserted. Then, the plug portion 1 is pushed until the upper end portion of the plug portion 1 is housed in the concave bottom surface 5. At this time, the upper end surface of the plug portion 1 is housed and held in the concave bottom surface 5 while being pressed against the lower edge of the concave bottom surface 5. As a result, the plug portion 1 is firmly connected to the holding portion 3. The reinforcing rod 4 may be simply inserted and fixed in the insertion hole 2 of the plug portion 1, but if the reinforcing rod 4 is fixed to the insertion portion with an adhesive or the like, the connection between the plug portion 1 and the holding portion 3 will be stronger, so that the present invention can be used. The effect is exerted more effectively. As another embodiment of the method of fixing the reinforcing rod 4, the reinforcing rod 4 may be threaded to form the insertion hole 2 slightly smaller than the reinforcing rod 4 so that the reinforcing rod 4 can be screwed and fitted. .

[0013]

[Effect of device]

 As described above, the present invention has the above-mentioned configuration, and therefore has the following effects.

Since an insertion hole was formed from the center of the upper end surface of the stopper to a predetermined position on the lower end surface, and a reinforcing rod was inserted into the insertion hole, the cork stopper was repeatedly pulled out from the bottle mouth, The cork does not collapse even after repeated packing, and it has a practical effect of providing a strong cork stopper with a simple structure.
