Description

[Detailed Description of the Invention] The present invention relates to a bottle opener that allows easy opening of a stopper inserted into the mouth of a bottle.

BACKGROUND ART Conventionally, to close the opening of a bottle containing sake, soy sauce, edible oil, etc., a method of sealing the bottle by inserting a stopper into the inner surface of the mouth of the bottle has been frequently used.

However, in order to open the stopper that is tightly fitted into the bottle opening,
The knob of the stopper exposed from the bottle mouth has a small diameter and is approximately the same diameter as the outer diameter of the bottle mouth.

■Because the gap between the stopper and the bottle opening was small, it was not easy to open the stopper by picking the entire stopper with your fingertips and pulling it upwards.

The present invention was devised in view of the above-mentioned drawbacks, and will be explained below based on one embodiment.

In the figure, 1 is a bottle opener according to the present invention, 2 is a bottle opening, 3 is a stopper inserted into the inside of the bottle opening 2, 4 is a knob of the stopper 3, and 5 is the bottle opening 2 and the stopper. 3, the bottle opener 1 has a substantially same shape consisting of a top wall 6 and side walls 7, 7, that is, the side walls 7, 7 are formed substantially parallel with a width corresponding to the outer diameter of the stopper, and the top wall The distance between the inner surface of 6 and the protrusions 8, 8 is approximately the same as the thickness of the knob 4 of the stopper 3.
It is composed of

Further, outwardly from the tips of the protrusions 8, 8, there are a top wall 6 that comes into contact with the knob 4 of the plug body 3, and side walls 7, 7 that restrict both sides of the plug body 3, and the protrusions 8, 8 is provided inward from the outer end of the ceiling wall 6.

The surfaces of the protrusions 8, 8 that come into contact with the lower end of the stopper knob are connected to the top wall 6.
and the thickness of the protrusions 8, 8 is such that the tip inserted into the gap is thin, and the tip is tapered inward from the tip to widen the gap. are doing.

Here, the term "inward" refers to the direction in which the stopper moves when the stopper is opened.

The bottle opener 1 of the present invention has protrusions 8, 8 with tapered tips protruding from the side walls 7, 7, so that it can be easily inserted into the fitting gap 5 between the bottle opening 2 and the stopper 3. is formed, and when the bottle opener 1 is moved horizontally, the gap 5 is expanded by the protrusions 8, 8, and the entire bottle 3 is pushed up without any force, and the bottle opener 3 is loosely inserted inside the bottle opening 2. The state will be as follows.

Then, when the bottle opener 1 is lifted upward, the bottle opening 2 of the bottle opener 3 is easily opened with the knob 4 being held between the top wall 6 of the bottle opener 1 and the projections 8, 8.

The bottle opener 1 of the present invention is not limited to the embodiments described above, and as shown in FIGS. The surfaces 8a, 8a that come into contact with the bottle opening 2 may be formed to be inclined.

As described above, the bottle opener of the present invention has protrusions 8, 8 protruding from the side walls 7, 7 with tapered ends, so that it can be easily inserted into the insertion gap 5 between the bottle opening 2 and the stopper 3. When the bottle opener 1 is moved horizontally, the gap 5 becomes the protrusion 8.
, 8, the stopper 3 fitted into the bottle opening 2 can be opened easily with a slight force.

Furthermore, the bottle opener of the present invention has a simple structure, consisting of a top wall and a side wall, and a protrusion with a tapered end protruding from the side wall, so it can be manufactured integrally by injection molding or the like using a plastic material.

Claims (1)

[Scope of utility model registration request] On both sides of the top wall 6, side walls 7, 7 are formed approximately parallel to each other with a width corresponding to the outer diameter of the stopper, and on the opposing inner surfaces of the side walls 7, 7, there are formed walls between the upper end of the bottle mouth and the lower end of the stopper knob. Projection 8 inserted into the gap
.
A top wall 6 that contacts the knob of the plug and side walls 7 that restrict both sides of the plug are provided outward from the tips of the protrusions 8, 8, and after the plug is brought into contact and restricted, The protrusions 8, 8 to be inserted are provided inward from the outer end of the top wall 6, and the surfaces of the protrusions 8, 8 that contact the lower end of the stopper knob are parallel to the top wall, and The bottle opener is characterized in that the protrusions 8, 8 have a thinner tip that is inserted into the gap, and a thicker tapered tip that pushes the gap inward from the tip.
