The container 50 has a frusto-conical pouring portion 51 for pouring out the contents F, and a leading end opening thereof serves as a pouring outlet 52. The spout 52 is sealed by, for example, a liner 53 made of aluminum. In addition, the above-mentioned pouring section 5
An annular protrusion 54 is formed in the vicinity of the base 1.

FIG. 2 is a perspective view showing the appearance of the seal member 30. As shown in FIG. Referring simultaneously to FIG.
Is made of, for example, low-density polyethylene, and has a substantially truncated cone shape with an open lower surface 31.
The peripheral portion 33 of the upper surface 32 of the seal member 30 has a cross section substantially L
A U-shaped annular groove 34 is formed. Further, a perforation 36 as a break portion is provided on the cylindrical portion 35 of the seal member 30 along the generatrix. This perforation 36,
The tubular portion 35 is provided from the lower surface 31 to the upper surface 32. Furthermore, along this perforation 36,
The seal member 30 extends from the lower surface 31 to the annular groove 34.
Is formed integrally with the handle 37. This handle 37
A board 37a protruding outward from the seal member 30; and a finger hook 37b extending in a direction perpendicular to the board 37a.
And A hook hole 39 is provided in the finger hook 37b. The inner surface 30a of the seal member 30
An annular groove 38 is formed in the lower part of the groove. The annular groove 38 is provided with the protrusion 5 formed on the pouring section 51 of the container 50.
4 (see FIG. 1), whereby the seal member 30 is firmly attached to the container 50.
That is, in order to remove the seal member 30, the tubular portion 35 must be broken, and therefore, the seal member 30 is in a state in which the seal member 30 cannot be removed.

The opening member 40 is made of, for example, a relatively hard resin such as polypropylene or polystyrene, and has a truncated conical shape with the lower surface 41 opened. A flange 42 is formed on a peripheral portion 43 of the lower surface 41. By forming the flange 42, the lower surface 4 is formed.
The shape of the peripheral portion 43 is substantially L-shaped. The substantially L-shaped peripheral portion 43 is connected to the seal member 30.
Are fitted in an annular groove 34 having a substantially L-shaped cross section, and are firmly attached to the seal member 30. That is, in order to remove the opening member 40 from the sealing member 30, the sealing member 30 must be broken,
The opening member 40 is in a state in which it is practically impossible to remove. Further, a protrusion 45 projecting into the opening member 40 is formed at a central portion on the inner side of the upper surface 44 of the opening member 40. The projection 45 has a triangular pyramid shape.

The opening of the spout 52 of the container 50 to which the cap C having the above structure is attached is performed as follows. That is, first, by pulling the tab 37 provided on the seal member 30, the tubular portion 35 of the seal member 30 is broken along the perforations 36 provided on the seal member 30. Since the seal member 30 is made of low-density polyethylene, it is easily broken. When the tubular portion 35 of the seal member 30 is broken, the tubular portion 35 can be expanded, so that the seal member 30 can be removed from the pouring section 51 of the container 50. In addition, the annular groove 34 can also be expanded along with this, so that the unsealing member 40 attached to the annular groove 34 can be removed from the seal member 30. Then, the opening member 40 is connected to the pouring section 51

Therefore, according to this embodiment, the opening member 40 cannot be removed unless the tubular member 35 is broken. Moreover, the tubular member 35 once broken cannot be returned to its original state. This makes it possible to determine at a glance whether the cap C attached to the container 50 has been once removed. As a result, unlike the conventional case, the cap is once removed and, for example, even if a drug or the like is injected with a syringe or the like, it is difficult to recognize the drug or the like. It is possible to ensure safety.

Further, since the projection 45 for opening the spout 52 of the container 50 is provided inside the opening member 40, it is possible to prevent germs and the like from adhering. Therefore, at the time of opening, it is possible to prevent contamination of the contents F with various germs and the like, which is sanitary. Moreover, the opening member 4 after opening.
0 can also be used as a cap for the container 50.

Note that the present invention is not limited to the above-described embodiment, and the seal member 30 may be a cylindrical member having open upper and lower surfaces. Cylindrical part 3 of seal member 30
The shape of 5 may also be a polygonal cross section. The annular groove 34 formed in the seal member 30 has L
The shape is not limited to the letter shape, and may be an inner expanding groove. further,
In addition to providing the perforations 36, a predetermined portion of the cylindrical portion 35 may be formed to have a small thickness.

In short, the present invention is applied to the case where the breaking strength of the cylindrical portion 35 is such that the sealing member 30 is to be removed from the pouring portion 51 or the opening member 40 is to be removed from the sealing member 30. It is only necessary that the first member be configured to have a strength that causes the tubular portion 35 to be broken first. Further, the shape of the spouting portion 51 of the container 50 is reversely tapered, that is, the side of the spout 52 is widened.
By making the inner circumference of the tapered portion a reverse taper shape, the seal member 30 cannot be removed unless the tubular portion 35 is broken.

In addition, if the unsealing member 40 is formed transparent, various design changes can be made without changing the gist of the present invention.

[0024]

According to this invention, the opening member cannot be removed unless the tubular portion of the sealing member is broken.
This makes it possible to determine at a glance whether or not the cap has been once removed, depending on whether or not the seal member has been broken, even if the seal has been opened improperly. Therefore, it is possible to prevent an unforeseen accident such as drug contamination, and to provide a cap with excellent safety.
