  1, 3, and 6, the first cam 8 is provided at a plurality of circumferential positions (up and down) on opposite surfaces of the lower end surface 4 g of the plug body 4 and the upper end surface 10 a of the safety seal ring 10 ( In the present embodiment, the case of two places is illustrated, but is not limited to this, and is formed as a protrusion 8a and a recess 8b. The protrusion 8a and the recess 8b connect the plug body 4 to the container body 1. At the time of rotation in the direction to be screwed onto (clockwise in plan view), the plug body 4 and the safety seal ring 10 have engaging contact surfaces 8c and 8d that rotate integrally, and in the opposite direction. At the time of rotation, only the plug body 4 has inclined surfaces 8e and 8f that slip and idle with respect to the safety seal ring 10. In addition, in this embodiment, the formation position of the connection piece 7 and the formation position of the first cam 8 are partially overlapped to facilitate molding, but are not limited thereto. You may form in the position which mutually shifted | deviated.

  As shown in FIGS. 1 and 2, the second cam 9 is provided at a plurality of locations in the circumferential direction on opposite surfaces of the inner peripheral surface 10b of the safety seal ring 10 and the outer peripheral surface 2b of the opening 2 of the container body 1 ( In this embodiment, the case of four places is illustrated, but it is not limited to this, and is formed as sawtooth-shaped projections 9a and 9b, respectively. Both these projections 9a and 9b When rotating in the direction in which the container main body 1 is screwed and attached (clockwise in the plan view shown in FIG. 2), only the safety seal ring 10 slips with respect to the opening 2 of the container main body 1 and idles 9c. 9d, and has locking contact surfaces 9e and 9f for locking the safety seal ring 10 to the opening 2 of the container body 1 when rotating in the reverse direction.

The second cam 9 is formed with an auxiliary projection 9g on the inner peripheral surface side of the safety seal ring 10. The auxiliary projection 9g is also formed with a locking contact surface 9h and an inclined surface 9i. However, the tip of the auxiliary projection 9g is a flat surface 9j, and the outer peripheral surface 2b of the opening 2 of the container body 1 is used. It is considered non-contact.
Further, the inner peripheral surface 10b of the safety seal ring 10 is made to correspond to the locking collar 2c formed at the lower part of the outer peripheral surface 2b of the opening 2 of the container body 1 (in FIG. 2, the projection 9b is formed). In this way, the safety seal ring 10 is separated from the plug main body 4. After that, the container body 1 is configured to be retained and held by the frictional force in the opening 2 of the container body 1. At the lower end of the inner peripheral surface 10 b of the safety seal ring 10, an annular protrusion is secured to the locking collar 2 c formed at the lower portion of the outer peripheral surface 2 b of the opening 2 of the container body 1. The strip 10c is formed, and this also holds the safety seal ring 10 after being separated from the plug body 4 in the opening 2 of the container body 1.

The embodiment of the container plug device according to the present invention has the above-described configuration, and the operation thereof will be described next.
The plug device of the present invention does not require the plug body 4 to be rotated a plurality of times each time the contents are used, so that it is not necessary to release the screwed relationship by the screw portion 4a. If the pull-top plug 3 is removed for the first time, the contents can be taken out from the opening hole after the pull-top plug 3 is removed. The opening 2 of the main body 1 can be closed. And when the remaining amount of the content is reduced and it is accumulated inside the pull-top inner plug 3 and cannot be completely removed to the end, the content can be removed by turning the plug body 4 and completely removing it from the container body 1. It can be completely removed and used until the end.

In addition, since the plug body 4 can be screwed into the opening 2 of the container body 1, it is not necessary to force-fit the plug body 4 into the opening 2 of the container body 1 and can be applied. The container is not limited to a hard container, and can be suitably applied to a soft flexible container such as a bag-shaped container.
Moreover, when the plug body 4 is unscrewed from the container body 1 and removed even once, the safety seal ring 10 is separated from the plug body 4, so that the presence or absence of opening can be confirmed. If the plug body 4 is removed from the opening 2 of the container body 1 in the distribution process from the production factory to the consumer's hands, etc. Since it can be visually confirmed that the ring 10 has been cut off from the plug main body 4, such a situation can be prevented.

Furthermore, since the cap 6 is connected to the side surface of the plug body 4 via the hinge portion 5, it is not lost.
Further, the pull-top inner plug 3 has a region 3b surrounded by a groove 3a formed on the top surface 4b of the plug body 4 along the cut outline, and a part of the region 3b and the connecting piece 3c are included. Therefore, the pull-top inner plug 3 can be easily removed to form the opening hole by pulling the finger ring portion 3d.

In addition, the plug body 4 has an annular portion 4c on which the cap 6 is fitted upright on the top surface 4b, and the pull-top inner plug 3 is accommodated in the annular portion 4c. 3 can be accommodated in the annular portion 4c and can be covered with the cap 6 in appearance, and after the pull-top inner plug 3 is removed, the annular portion 4c is removed from the container body 1 when the contents are taken out. It can be used as an extraction cylinder.
The cap 6 includes a top plate 6a, an outer peripheral wall 6b extending downward from the periphery of the top plate 6a, and an inner peripheral wall 6c extending downward from the top plate 6a inside the outer peripheral wall 6b. Since the peripheral wall 6b and the inner peripheral wall 6c have a structure in which the annular portion 4c of the cap body 4 is sandwiched and closed from inside and outside, the sealing performance in the closed state of the cap 6 can be improved.

The hinge portion 5 includes a series of connecting pieces 5a and 5b that are connected to the upper side surface of the cap body 4 and the lower side surface of the cap 6, and is elastic at the center of these connecting pieces 5a and 5b. Since the deformable thin part 5c is formed in a series, the cap 6 is connected to the cap body 4 in series, so that the cap 6 can be prevented from being lost and the cap 6 can be opened and closed. Can be easily done with one touch.
Further, the first cam 8 is formed as protrusions 8a and recesses 8b at a plurality of locations in the circumferential direction on the upper and lower opposing surfaces of the lower end surface 4g of the plug body 4 and the upper end surface 10a of the safety seal ring 10, These protrusions 8a and recesses 8b are engagement contact surfaces on which the plug body 4 and the safety seal ring 10 rotate integrally when the plug body 4 is rotated in the direction in which the plug body 4 is screwed onto the container body 1. 8c and 8d, and when rotating in the opposite direction, only the plug body 4 has inclined surfaces 8e and 8f that slip and idle with respect to the safety seal ring 10, and the second cam 9 Are formed as protrusions 9a and 9b at a plurality of locations in the circumferential direction of the surface facing the inner peripheral surface 10b of the safety seal ring 10 and the outer peripheral surface of the opening 2 of the container body 1, respectively. 9b, the plug body 4 is screwed onto the container body 1. When rotating in the direction, only the safety seal ring 10 has inclined surfaces 9c and 9d that slip and idle with respect to the opening 2 of the container body 1. When rotating in the reverse direction, the safety seal ring 10 is Since the locking contact surfaces 9e and 9f for locking and locking the opening 2 of the container body 1 are provided, when the plug body 4 is first screwed into the opening 2 of the container body 1, With one cam 8, the safety seal ring 10 can be rotated integrally with the stopper body 4, and the stopper body 4 and the safety seal ring 10 can be tightened and attached to the opening 2 of the container body 1 to the end. At this time, the second cam 9 does not prevent the plug body 4 from being mounted because both the protrusions 9a and 9b slip on the inclined surfaces 9c and 9d and idle. However, when the plug body 4 is rotated in the direction opposite to the above, the second cam 9 prevents the safety seal ring 10 from rotating, and the first cam 8 slips on the inclined surfaces 8e and 8f to cause the plug body 4 to rotate. Therefore, it is possible to confirm that the safety seal ring 10 is reliably cut off at the position of the thin connecting piece 7 and opened.

  The container stopper device according to the present invention comprises the above embodiment, but the present invention is not limited to this embodiment, and is free within the scope of the matters described in the claims of the utility model registration. It can be implemented by changing. For example, the shape of the container body 1 can be applied to a bottle shape, a box shape, a tube shape, a bag shape, and other container shapes, and can be applied to both hard and soft shapes. Further, the outline shape of the pull-top plug 3 may be a circle, an ellipse, a star, or other shapes.
