DETAILED DESCRIPTION OF THE INVENTION The bottle 1 shown in FIG. 1 comprises a part 9 forming a storage container and a closure 4. The part 9 forming the storage container constitutes the body 2 and has an axis X at its upper end.
A threaded neck 3 is provided with which a closure 4 can be screwed.

The sealing plug comprises an inner sealing base 5, an outer cap 6 fixed to the inner sealing base 5, and a metal ring 12 attached to a lower end of the outer cap 6.

The part 9 forming the storage container is made of glass or a rigid or semi-rigid plastic material in a two-step process.

The neck 3 is first made with the parison, after which the parison is blow molded to form the body 2. This is known to those skilled in the art.

In this example, the body 2 has a substantially rectangular cross-section and has two substantially flat and parallel major surfaces 10.
And two shoulders 13 on each side of the neck 3 in the upper portion of the body 2. The joint surface 11 of the main body 2 extends along the diagonal of the bottle as shown. The inner sealing cap 5 and the outer cap 6 are molded from a plastic material.

When the body 2 is blow-molded, the two alignment abutments 15 are close to the neck 3 at the shoulder 1 of the bottle.
3 is formed. Although only one is visible in FIG. 1, two abutments are arranged on the joint surface 11 on the opposite side of the diameter with respect to the axis X of the neck 3.

Therefore, the positioning of the directional contact portion 15 in the main body 2 is constant. In another embodiment, not shown, the body 2 has only one alignment contact 15
Is formed.

The upper portion 20 of the cap 6 has an elongated shape having an axis Y perpendicular to the axis X. The axis Y is required to be parallel to the main surface 10 of the main body 2 when the bottle is closed. As shown in FIG. 2, the lower part 21 of the outer cap 6 comprises an outer skirt 22 and an inner skirt 23, which are cylindrical and coaxial, and which are made of plastic material integrally with the upper part 20. Is molded.

The inner skirt 23 has a substantially circular cross section and secures the outer cap 6 to the inner sealing base 5, preferably the inner sealing base has a peripheral line parallel to the axis X. A ridge is provided for attaching the inner cap 5 to the outer cap 6 by an interference fit.

In this example, the outer skirt 22 has a substantially square cross-section and the inner skirt 23 is joined to the inner surface of the four sides of the outer skirt 22 at four locations 24 around its circumference. , A cavity 25 is formed in relation to the four inner corners of the outer skirt 22.

The lower end of the outer skirt 22 has at least one
Abutment surface 30 is contoured and preferably has two such surfaces as shown in the example shown, each being adapted to cooperate with the alignment abutment 15;
Ensure that the closure does not move from the required angular position when the bottle is closed.

As shown in FIG. 3, the contact surface 30 is formed over the entire thickness of the outer skirt 22, and
Is parallel to

In order to prevent the stopper from being loosened by itself, a screw loosening prevention projection 31 is formed within the thickness of the outer skirt 22 and is spaced apart from the contact surface 30 by the contact surface 30. Is lower than.

More specifically, a gap 36 is formed between the protrusion 31 for preventing screw loosening and the contact surface 30,
Its width is slightly larger than the width of the alignment contact portion 15.

When screwing the hermetic plug 4 to the neck 3, first, the protrusion 31 for preventing screw loosening crosses the alignment contact portion 15 by elastic deformation, and then the abutment surface 30 abuts on the alignment contact portion 15. Engagement provides the user with a "dead end" feel that confirms that the bottle has been properly closed.

The screw loosening prevention projection 31 prevents the stopper from moving in the opposite direction by itself, for example, due to the elastic deformation of the inner sealing base 5.

Therefore, in order for the user to unscrew the stopper,
A relatively large force must be applied so that the protrusion 31 for preventing the screw from loosening over the alignment contact portion 15.
