The container body 2 in the illustrated example has a mouth and neck portion 5 standing up from a trunk portion 3 via a shoulder portion 4, and a locking projection 6 is provided around the outer periphery of the mouth and neck portion 5.
[0011]
The inner plug 1 according to the present invention is made of a synthetic resin. As shown in the drawing, the inner wall 1 is fitted with a peripheral wall 7 on the outer periphery of the container body neck 5 and protrudes from the inner peripheral surface of the peripheral wall 7. It has a configuration in which the strip 8 is moved over and engaged with a locking projection 6 provided on the outer periphery of the mouth-and-neck portion 5 so as to prevent the strip 8 from being removed, and is usually not mounted until it is discarded after being mounted on the container body 2. Therefore, the thing provided with the spout or the part provided with the cutting part at the part to be the spout, and the form in which the cap is detachably attached to the container body or the inner plug itself can be mentioned.
[0012]
In the illustrated example, a top wall 9 that abuts the lower surface on the upper surface of the mouth neck portion 5 is extended inward from the upper edge of the peripheral wall 7, a support cylinder 10 is erected above the inner edge of the top wall 9, and a container is disposed below. A seal cylinder 11 is provided in close contact with the inner periphery of the body neck 5 to prevent leakage of liquid therefrom. Further, the upper end edge of the support tube 10 is connected to the middle portion of the outer periphery of the pouring tube 12 whose upper end extends in a trumpet shape. Further, a bottom plate 13 is extended from the lower edge of the dispensing tube 12, and a cutout portion 13a surrounded by a thin broken line 14 is provided on the bottom plate 13, and a bar-like shape standing from the top surface of the cutout portion 13a. The pull ring 16 extends horizontally from the tip of the protrusion 15 and the pull ring 16 is pulled up to break the thin broken line 14 so that the cut portion 13a is removed and the spout is opened.
[0013]
The inner plug 1 of the present invention includes a plate-like protrusion 17, a handle 18, and a thin broken part 19 for easy removal from the container body 2 after use. The plate-like projection 17 is erected on the top edge that is continuous with the upper edge of the outer surface of the peripheral wall 7. In this embodiment, the plate-like protrusion 17 has a curved rectangular plate shape with the outer surface positioned on the same plane as the outer peripheral surface of the peripheral wall 7. And has a thickness that can be elastically deformed when the handle 18 is rotated.
[0014]
The handle 18 has a horizontal ring shape that extends along the peripheral wall 7 from the upper end of the plate-like protrusion 17 and is rotatable around the plate-like protrusion 17 portion. In this embodiment, the support cylinder 10 is erected from the inner portion of the handle 18 on the top surface of the top wall 9, and the outer peripheral surface of the support cylinder 10 and the inner peripheral surface of the handle 18 are separated by a plurality of breakable bars. The connecting pieces 20 are connected.
[0015]
The thin-walled fracture portion 19 is composed of a horizontal thin-wall portion 19a that surrounds the inside and both sides of the plate-like protrusion 17, and a pair of vertical thin-wall portions 19b that vertically cut the peripheral wall 7 at the positions on both sides of the plate-like protrusion 17. Various forms of the thin-walled fracture portion 19 can be adopted, for example, a thin-walled portion can be formed by forming a narrow groove in the corresponding portion, and the narrow groove forming surface in this case may be the inner surface of the corresponding portion It may be the outer surface. In the illustrated example, the horizontal thin portion 19a is formed on the outer surface, and the vertical thin portion 19b is formed on the inner surface with a narrow groove. In the figure, reference numeral 21 denotes a cap.
[0016]
The inner plug 1 configured as described above can be integrally formed of synthetic resin with the handle 18 positioned above the peripheral wall 7 as shown in FIG. In use, the inner stopper in this state is driven from above the container body 2 so that the engaging protrusion 8 gets over the engaging protrusion 6 and engages.
[0017]
At the time of disposal after use, when the handle 18 is forcibly pulled up and rotated, each bar-like connecting piece 20 is cut, and then when the handle 18 is rotated 180 degrees and further lowered, The peripheral wall 7 can be cut, and the peripheral wall 7 can be cut into a vertically long band shape. The inner plug 1 from which the peripheral wall 7 has been cut can be easily removed from the container body 2 because the peripheral wall in the vicinity where the peripheral wall 7 has been cut is easily deformed.
[0018]
【The invention's effect】
As described above, the inner plug of the present invention has the above-described structure, so that once it is fitted to the container body, it is firmly fixed, and there is no inconvenience such as inadvertent disconnection. Since the peripheral wall can be cut into a strip shape by being pulled down after being rotated, the peripheral wall after the cut is easily deformed. As a result, the peripheral wall can be easily detached from the container body and can be easily separated.
[0019]
In addition, the support cylinder 10 is erected from the inner side of the handle on the top surface of the top wall 9 extending inwardly from the upper edge of the peripheral wall 7, and the outer peripheral surface of the support cylinder 10 and the inner peripheral surface of the handle 18 are spaced apart from each other in the circumferential direction. In the case of connecting by a plurality of breakable rod-like connecting pieces 20, the handle does not move inadvertently during use, and it is possible to prevent as much as possible the occurrence of inadvertent breakage of the thin-walled breaking portion due to external force It has advantages [Brief description of the drawings]
