As shown in FIG. 1, the lid of this medicinal bottle can be fitted to the base body 1 formed in a reverse bottomed cylindrical shape by a soft metal thin plate such as aluminum, and the inside of the top surface of the base body 1. ,and,
It is configured by a combination of an inner lid 2 formed in a similar shape to the base body 1 and a synthetic resin outer lid 3 that can be attached to the upper half including the top surface portion of the base body 1.

The base body 1 is formed in an inverted bottomed cylindrical shape by forming a top surface plate 12 on the upper surface of the peripheral body portion 11 having an appropriate height. 13 is a through hole drilled in the center of the top plate 12;
As shown in FIG. 2, the upper surface of the rubber stopper 5 fitted in the bottle mouth of the medicinal bottle 4 can be exposed through the through-hole 13.

14 is a groove having an appropriate width formed around the through hole 13 formed in the top plate 12;
Two slits 16 and 17 are engraved so as to reach the upper end portion of the peripheral body portion 11 from the top plate 12 where both end portions of the groove 14 are formed, thereby causing the inner side surrounded by the groove 14 to be peeled off. The ring 15 is configured. Reference numeral 14 a denotes a slit provided in the top plate 12 so that the base body 1 can be easily peeled off when the base body 1 is peeled from the bottle mouth of the medicinal bottle 4. Reference numeral 19 denotes a winding position when the base body 1 is wound around the bottle mouth portion of the medicinal bottle.

The inner lid 2 is formed in an inverted bottomed cylindrical shape by continuing the top plate 22 on the upper end of the peripheral body portion 21, has a similar shape to the base body 1, and has a size that can be fitted to this. It is formed as. In this embodiment, the inner lid 2 is formed of a soft metal thin plate such as aluminum which is the same material as the base body 1, but the inner lid 2 may be formed of a synthetic resin.

As shown in FIG. 2, the height of the above-described peripheral body portion 21 is formed lower than the height of the flange of the rubber plug 5 so that it can be in close contact with the peripheral cylinder of the flange of the rubber plug 5 during use. is there.

Reference numeral 23 denotes a through hole formed in the top plate 22 of the inner lid 2, and the size of the through hole 23 is smaller than that of the through hole 13 formed in the top plate of the base body 1. As a result, when the outer lid 3 is peeled and removed, the locking projection 39 released from the inner lid 2 can be pulled up to the upper surface through the through hole 13 of the base body 1 (see FIG. 2).

The outer lid 3 to be crowned on the upper surface of the base body 1 is formed using a synthetic resin having an appropriate hardness and has a shallow inverted plate shape in which the peripheral body portion can be slightly covered with the peripheral body portion 11 of the base body 1. It is formed as follows.

As shown in FIG. 2, a locking projection 39 that can be bent and locked while being in contact with the circumference of the through hole 23 formed in the inner lid 2 is provided at the center of the rear surface of the outer lid 3. After being fitted into the through-hole 23, it is provided so as to be foldable so as to be laid down by being bent and pressed from the inner side of the inner lid 2 or similarly heated from the inner side.

  Next, the basic configuration of the base body 1 according to the present invention will be described in detail with reference to FIG.
