Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plug-type separation and recovery plastic cap that is attached to the mouth and neck of a bottle containing low-viscosity contents such as soy sauce.
[0002]
[Prior art]
Recently, from the standpoints of environmental protection and resource saving, a stopper-type plastic cap for separating and collecting has been developed and put into practical use in consideration of the ease of disposal and recycling of bottles using the contents. As this plastic cap (10), for example, as shown in FIG. 3, a lid (200) is connected to the cap body (100) via a hinge part (300) so that it can be opened and closed. ) Has an occlusal ring (22) of the bottle (20) and an occlusal ring (111) that engages at the time of capping on the inner side of the lower end of the peripheral wall (110), and a thin and weak line (101) for separating and collecting the upper end of the peripheral wall The top plate (120) is connected via the fitting, and the fitting having the fitting portion (131) fitted to the fitting concave portion (211) having the fitting portion (212) of the lid portion on the upper surface of the outer peripheral edge of the top plate. A pour ring (130) is provided, a pour pipe (140) is erected on the inner side of the puff ring, and a pull ring ( 153) with a column (152) standing on the periphery A plate (150) is provided, and a contact ring (121) that is in close contact with the top surface of the mouth and neck (21) of the bottle (20) is provided on the outer peripheral edge of the lower surface of the top plate (120). An inner ring (160) is provided for tightly sealing the inner surface of the mouth and neck of the bottle, and the lid (200) has a fitting portion (131) of the cap body (100) inside the lower end of the peripheral wall (210). A fitting recess (211) having a fitting part (212) to be fitted and a fitting ring (130) having the fitting ring (130) is provided. There is known a structure in which an inner ring (230) which is in close contact with the inner ring is suspended.
[0003]
[Problems to be solved by the invention]
However, the above-described conventional stopper-type plastic cap for separation and collection is opened by opening the lid and pulling the pull ring in the dispensing cylinder of the cap body with a finger to cut the thin fragile line and remove the sealing plate. After pouring out the contents, as shown in FIG. 4, in order to reseal the bottle (20), the lid (200) is snapped close to the cap body (100) (indicated by an arrow). The contents (30) adhering to the upper surface of the peripheral wall (110) and the outer peripheral surface (B part) of the fitting ring (130) are scattered around the cap by the principle of a water gun, and the tabletop and clothes worn It was possible to get dirty. Moreover, the thin weak line for separation collection provided in the cap main body may be cut by the external pressure applied to the lid portion when the bottle neck is plugged.
[0004]
The present invention solves the above-mentioned problems of the conventional stopper-type plastic cap for fractional collection, and after the contents are poured out, the lid is snapped on the cap body to re-seal the bottle. The contents attached to the outer peripheral surface of the cap body when it is closed will not scatter to the surroundings, and the cap body will be affected by the external pressure applied to the lid when it is plugged into the mouth and neck of the bottle. It is intended to provide a plug-type separation / recovery plastic cap that does not cut the thin line of weakness for separation / recovery provided in the container.
