Description

  The present invention relates to a dual-component mixing cap and a container with a dual-component mixing cap.

  Conventionally, the auxiliary agent (additive) is contained in the cap so as to be pourable, and the auxiliary agent in the cap can be poured out immediately before use, etc., and the auxiliary agent can be mixed in the container contents. Agent mixing caps are known.

  Such a two-component mixing cap has an inner peripheral wall disposed along the inner wall of the opening of the container, and a base in which an outer peripheral wall integrally connected to the inner peripheral wall is screwed to the outer side of the opening of the container; The rotary cover body having an inner cylinder which is rotatably held at the outside of the upper end opening of the upper cover and has an inner cylinder opened toward the lower end opening of the inner peripheral wall inside, and is disposed in the inner cylinder of the rotating cover body There is known a two-component mixing cap provided with an inner container body for containing an auxiliary agent (see, for example, Patent Document 1).

  In the two-component mixing cap described in Patent Document 1, at least one protrusion is provided on the inner wall of the inner cylinder, and the inner peripheral wall of the base is detachably fitted at the lower end opening thereof and directed to the rotating cover body A bottom lid provided with a cutter is provided, and at least one longitudinal groove extending straight from the upper end opening toward the lower end opening is provided, and the inner container body has a convex portion adapted to the longitudinal groove of the inner peripheral wall And an inclined groove extending from the bottom to the top on the outer surface of the body in cooperation with the projection provided on the inner wall of the inner cylinder, and the bottom cover is lowered by the lowering of the inner container body, There is provided a pressing piece which abuts on the lower end portion of the inner container body to release the fitting at the lower end opening of the inner circumferential wall and which allows the contents discharged from the inner container body to fall into the container.

  And in the two-component mixing cap described in Patent Document 1 configured as above, when the rotary cover body is rotated at the upper end opening of the inner peripheral wall, it is linked to the inclined groove provided on the outer surface of the barrel of the inner container body. The projection in the inner cylinder moves along the inclined groove, and the inner container body slides downward, and the inner container body is unsealed by cutting with a cutter, and the contact with the pressing piece of the bottom lid The fitting on the inner peripheral wall of the bottom lid is released, and the auxiliary agent falls into the container.

  However, in the two-component mixing cap described in Patent Document 1, when attempting to attach and detach the two-component mixing cap to and from the container after the adjunct dispensing, the separate cover from the rotating cover body operated at the adjunct dispensing is used. Since the base screwed to the barrel of the container must be directly rotated, the parts operated at the time of auxiliary agent dispensing and the parts operated at the time of attaching and detaching the dual agent mixing cap are different, There is a problem that the operation of the two-component mixing cap becomes complicated.

  Then, the present applicant proposed the two-component mixing cap described in Japanese Patent Application No. 2014-19890 as a two-component mixing cap that solves the above-mentioned problems.

  As shown in FIG. 8, the two-component mixing cap described in this Japanese Patent Application No. 2014-19890 is provided with a cap body 520 attached to the cylindrical portion of the container port, an upper lid 530 attached to the cap body 520, and an inner side of the upper lid 530.

When the upper cover 530 is rotated in the other direction while the inner member 540 is moved downward with respect to the upper cover 530 and the inner member 540 is moved downward with respect to the upper cover 530, The upper cover 530 is integrated with the member 540 and the upper cover 530 integrated, enabling removal of the two-component mixing cap 510 from the container port cylinder and moving the inner member 540 downward with respect to the upper cover 530. When rotated in one direction, the cap main body 520, the inner member 540, and the upper lid 530 are integrated, and it is possible to attach the two-component mixing cap 510 to the container opening cylindrical portion.

  In the two-component mixing cap 510 described in the Japanese Patent Application No. 2014-19890, the container contents are prevented from backflowing and entering into the auxiliary agent storage portion 550 with the inner member 540 disposed at the lowermost portion. With the inner member 540 disposed at the lowermost portion for the purpose, seal convex portions 536 and 537 formed on the inner peripheral surface of the skirt portion 535 of the upper lid 530 are in close contact with the annular peripheral wall 542 of the inner member 540 At the same time, the seal ring 544a formed on the tapered portion 544 of the inner member 540 is configured to be fitted in a close contact with the seal receiving recess 521a of the cap body 520.

Further, a rotation restricting portion 70 that restricts the rotation of the inner member 40 in the closing direction with respect to the cap main body 20 is formed between the cap main body 20 and the inner member 40.
As shown in FIG. 1 and the like, the rotation restricting portion 70 is composed of a main body side engaging portion 22 b of the cap main body 20 and an inner member side engaging portion 45 b of the inner member 40.
The inner member side engaging portion 45b engages with the main body side engaging portion 22b in any state where the inner member 40 is disposed at the uppermost portion and the lowermost portion with respect to the upper lid 30. Designed with dimensions.

  Further, between the upper lid 30 and the cap main body 20, while permitting the rotation of the upper lid 30 in the closing direction with respect to the cap main body 20, the rotation in the opening direction (the other direction, counterclockwise in this embodiment) A one-way clutch portion 80 for blocking is formed.

  Next, the method of pouring out the auxiliary agent will be described below based on FIGS. 1 and 2.

First, as shown in FIG. 1, the upper lid 30 is rotated in the closing direction from the state in which the inner member 40 is disposed at the top with respect to the upper lid 30.
Then, when the upper lid 30 is rotated in the closing direction with respect to the rotation restricting portion 70 which regulates the rotation of the inner member 40 in the closing direction with respect to the cap main body 20, the inner member 40 is lowered with respect to the upper lid 30. The inner member 40 is moved downward by the screwing portion 60 designed to move to the At this time, the upper and lower positions of the upper cover 30 do not change.

  Next, as shown in FIG. 2, when the inner member 40 is moved downward, the weakened portion 22 a of the cap body 20 is broken by the cylindrical portion 45 of the inner member 40, and the outlet 22 c is formed in the cap body 20. And the bottom wall of the receiving recess 22 is pushed to move downward, and the first seal portion 45a also moves downward, and the inner peripheral surface of the cylindrical portion 45 and the outer periphery of the column portion 32 of the upper lid 30. An auxiliary agent injection path is formed between the surfaces, and the auxiliary agent is injected into the container 90.

  Next, the method of attaching and detaching the dual-component mixing cap 10 to and from the container 90 after the auxiliary agent injection will be described below.

First, when the dual agent mixing cap 10 is removed from the container 90 after the auxiliary agent is poured out, the upper lid 30 is rotated in the opening direction, as in the case of a normal cap.
Then, since the relative rotation between the cap main body 20 and the upper lid 30 is blocked by the one-way clutch portion 80, the cap main body 20 is rotated in the opening direction together with the upper lid 30. Since the relative rotation between the inner member 40 and the inner member 40 is prevented, the inner member 40 is rotated in the opening direction together with the cap body 20. Thereby, the cap main body 20, the upper lid 30, and the inner member 40 integrally rotate in the opening direction, and the engagement between the main body side screw portion 24 of the cap main body 20 and the container side screw portion 92 of the container 90 is released. , The two-component mixing cap 10 is removed from the container 90.

  In addition, it is the same as that of the above also about the method of removing the 2 agent mixing cap 10 from the container 90 in the state before auxiliary agent injection | pouring.

In addition, when the dual agent mixing cap 10 is attached to the container 90 after the auxiliary agent is poured out, the upper lid 30 is rotated in the closing direction as in the case of a normal cap.
Then, since the inner member 40 is completely lowered to the lowermost part, the rotational force of the upper cover 30 is transmitted to the inner member 40, and the inner member 40 is rotated in the closing direction together with the upper cover 30. Thus, the relative rotation between the cap body 20 and the inner member 40 is prevented, so that the cap body 20 rotates in the closing direction together with the inner member 40. Thereby, the cap main body 20, the upper lid 30, and the inner member 40 integrally rotate in the closing direction, and the main body side screw portion 24 of the cap main body 20 and the container side screw portion 92 of the container 90 are engaged. Is attached to the dual-component mixing cap 10.

  As mentioned above, although the embodiment of the present invention has been described in detail, the present invention is not limited to the above embodiment, and various design changes may be made without departing from the present invention described in the claims. It is possible.

  For example, the specific embodiment of the auxiliary agent targeted by the present invention may be any one such as solid or liquid, and the container contents may be solid or liquid, etc. Anything may be used. In addition, when the container contents (main agent) is a liquid containing carbonic acid such as carbonated beverages, the pressure in the container tends to be higher than the pressure in the auxiliary agent storage unit, so a gas flow passage is formed. The effect by doing becomes even more remarkable.
