At the base end of the mouth portion 17, one stop projection 23 is provided on each side of the mouth portion 17 (two in total).

  An inner cap 26 is fitted in the mouth portion 17. The inner cap 26 has a sealing portion 27 that closes the opening of the mouth portion 17. As shown in FIG. 3, the sealing portion 27 is made of a disk-shaped member, and is connected to the inner peripheral surface of the inner cap 26 via a thin portion 29 at the outer peripheral edge.

  The outer cap 14 includes a cap body 28 and an upper cap 30 formed integrally with the cap body 28 and the hinge portion 32.

  The cap body 28 has a spout 34, a female screw 36, and an opening portion 38. In the case of this figure, the cap body 28 includes a ceiling portion 31 and a skirt portion 33 formed integrally with the outer peripheral edge of the ceiling portion 31. A spout 34 is formed in the ceiling portion 31. The spout 34 is formed at a position connected to the opening 18 of the container body 12, that is, on the same axis as the opening 18 in this embodiment. The spout 34 is closed by the upper cap 30.

  An opening 38 and a female screw 36 are formed on the opposite side of the spout 34 across the ceiling 31. The unsealing part 38 has a cylindrical shape whose outer shape is smaller than the outer diameter of the sealing part 27 and is disposed above the sealing part 27. A male seal portion 35 is formed on the ceiling portion 31 side portion of the opening portion 38. The male seal portion 35 is formed by expanding the opening portion 38 so as to have an outer diameter slightly larger than the inner diameter of the inner cap 26. The female screw 36 is formed so as to be fastened to the male screw 20 (FIG. 2) formed in the mouth portion 17 of the container body 12. The opening portion 38 and the female screw 36 are covered with the skirt portion 33.

The unsealing prevention body 16 is mounted between the lower end edge of the skirt portion 33 and the guide portion 22 of the container main body 12. As shown in FIG. 4, the unsealing prevention body 16 is a separate body from the outer cap 14 and has a C shape in which a part of the annular body in the circumferential direction is opened in plan view. The unsealing prevention body 16 has an annular portion 40 and an opening end portion 42 formed at one end of the annular portion 40. On the inner peripheral surface of the annular portion 40, a convex portion 44 that protrudes inward in the radial direction and a concave portion 46 that constitutes a drop-off prevention mechanism for preventing the unsealing prevention body 16 from dropping from the container body 12 are formed. ing. The anti-opening body 16 is formed so as to be elastically deformable in the radial direction by increasing or decreasing the distance between the opening end portions 42. In the case of this embodiment, the unsealing prevention body 16 is formed so as to be symmetric between the front surface and the back surface in the thickness direction.

The unsealing prevention body 16 is attached to the container main body 12 by inserting the opening end portion 42 along the guide portion 22 from the radial direction of the container main body 12. In this state, the opening prevention member 16, the fitting of the projection 24 provided on the guide portion 22 of the recess 46 and the container body 12 formed in the annular portion 40 constituting the captive, fixed to the container body 12 (FIG. 5). Next, the female screw 36 of the outer cap 14 is screwed into the male screw 20 of the mouth portion 17 of the container body 12 until the lower end edge of the skirt portion 33 contacts the unsealing prevention body 16 (FIG. 1). When the lower end edge of the skirt portion 33 contacts the unsealing prevention body 16, the outer cap 14 is held before the unsealing portion 38 contacts the sealing portion 27.

(Operation and effect)
The bottle container 10 configured as described above prevents the contents contained in the container body 12 from being exposed to the outside air when the container body 12 is sealed with the inner cap 26 in a state before use. (Figure 3). When starting use, the user pushes and widens the opening end 42 and elastically deforms the opening prevention body 16 in the radial direction , thereby removing the opening prevention body 16 from between the outer cap 14 and the guide portion 22 of the container body 12. Remove (Figure 6).

  By removing the anti-opening body 16, the outer cap 14 can be further screwed into the container body 12. The outer cap 14 is moved in the axial direction by further screwing by the user, and the opening portion 38 enters the opening 18. The opening part 38 pushes down the sealing part 27 by the outer cap 14 being screwed and further moving in the axial direction. The outer cap 14 is screwed in until the stop piece 25 formed on the cap body comes into contact with the stop protrusion 23. If it does so, a part of thin part 29 which has connected the sealing part 27 and the internal peripheral surface of the inner cap 26 will be cut | disconnected. The sealed portion 27 maintains the state of being connected to the inner peripheral surface of the inner cap 26 at the other part of the thin portion 29 and hangs down. The opening portion 38 advances to the back of the opening 18, and the male seal portion 35 contacts the inner peripheral surface of the inner cap 26. In this way, the opening 18 is opened and connected to the spout 34 (FIG. 7).

In the present embodiment, by which the opening prevention member 16 and elastically deformable C-shaped, remove the outer cap 14 Succoth no can extract the opening prevention member 16. Therefore, the bottle container 10 can be easily used because the unsealing prevention body 16 can be easily removed as compared with the conventional case in which the outer cap 14 needs to be removed or disconnected from the outer cap 14. .

The unsealing prevention body 16 can improve the mechanical strength by providing the convex portion 44 projecting radially inward on the inner peripheral surface of the annular portion 40 .

(Modification)
The present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the gist of the present invention.

The unsealing prevention body 16 may be formed so that the thickness decreases from the annular portion 40 toward the opening end portion 42. By forming in this way, the opening part of the unsealing prevention body 16 can be expanded with a small force, and can be more easily inserted between the outer cap 14 and the guide part 22 of the container body 12 .

Moreover, although the drop prevention mechanism has been described with respect to the case where it is configured by the protrusion 24 provided on the guide portion 22 of the container body 12 and the recess 46 formed in the unsealing prevention body 16, the present invention is not limited thereto. The drop-off prevention mechanism may be configured by a recess 46 formed in the guide portion 22 of the container body 12 and a protrusion 24 formed on the unsealing prevention body 16.
