Description

The present invention relates to a two-agent mixed cap, and more particularly to a two-agent mixed cap capable of mixing two separately stored two agents by a simple operation.

As a two-agent mixing container in which two agents are mixed and used immediately before use, the first agent is stored in the container body, the second agent is mounted above the mouth of the container body, and the lower end opening is sealed with a sheet. A mixing container in which the two agents are mixed by being housed in a cup-shaped container and breaking the sheet with a breaking blade has been conventionally known (see, for example, Patent Document 1).

JP-A-2007-204105

However, the two-agent mixing container described in Patent Document 1 holds the storage container containing the second agent upside down inward of the inner cylinder of the upper cap, and has an upward breaking blade directly below the container. If the storage container is dropped due to impact or vibration during transportation, the sheet may be broken.
Further, when the sheet is broken, the sheet forms an uncut portion in a part and hangs down, and the second agent in the storage container is dropped into the container body. Therefore, if the second agent is a liquid substance, it is still possible. If the second agent is powdery, granular, jelly, solid, etc., the second agent may not be sufficiently removed.
Furthermore, after removing the sealing band, the screw of the upper cap is pushed around to break the sheet and the lid wall with a breaking blade, and the second agent is dropped into the container body and mixed, and then the lower part is used. There is a problem that it is difficult for the user to understand and it takes time and effort because the cap must be rotated in the opposite direction to remove the entire cap.

The present invention has an object of solving the above-mentioned problems, and only by a normal opening operation of screwing out a screw, not only a liquid substance but also a powdery substance, a granular substance, a jelly form, or a solid substance can be used as a second agent. It is an object of the present invention to provide a two-agent mixing cap capable of reliably mixing even such a substance.

Next, the usage mode and the action and effect of this example will be described.

In this embodiment, the container body A is filled with a first agent (not shown), and the second agent a is filled in the storage cylinder 10 of the inner cap B.
To attach the two-agent mixed cap of this embodiment to the container body A, fill and store the second agent a in the storage cylinder 10 of the inner cap B, then screw and tighten the outer cap C to tighten the inner cap B. After assembling the outer cap C, the first screw portion (female screw) 8 of the inner cap B is applied to the first screw portion (male screw) 2 of the mouth portion 1 of the container body A filled with the first agent and screwed. To wear.

When the second agent a is stored in the storage cylinder 10 of the inner cap B, and then the second screw portion (female screw) 39 of the outer cap C is screwed into the second screw portion (male screw) 17 of the inner cap B and tightened. The outer cap C is rotated in the closing direction, the engaging arm 41 of the outer cap C gets over the engaging protrusion 20 of the inner cap B, and the rotation of the outer cap C is allowed.
Further, since the inner cap B has not yet been screwed into the mouth portion 1 of the container body A, the outer cylinder 5 can be slightly deformed, and the diameter-reduced step portion 43 of the sealing ring 33 of the outer cap C is the outer cylinder. It is possible to get over the height of the protrusion 23 of 5 and descend.
The outer cap C can be tightened to the inner cap B by fixing the inner cap B with a jig (not shown).

When the outer cap C is lowered by screwing, the second engaging protrusion 40 of the engaging portion 35 comes into contact with the first engaging protrusion 21 of the tubular wall 18, and by further lowering. , The second engaging protrusion 40 gets over the first engaging protrusion 21 and fits into the inner peripheral surface of the tubular wall 18.
Further, the outer cap C is lowered, and finally, the pouring cylinder 16 at the upper part of the outer storage cylinder portion 14 is abutted and fitted to the seal cylinder portion 37, and the lower end surface of the screw cylinder portion 38 is attached to the upper wall 7. The second screw portion (male screw) 17 and the second screw portion (female screw) 39 are abutted and fastened.

When the fastening of the second screw portion (male screw) 17 and the second screw portion (female screw) 39 is completed, the ratchet mechanism is in the set state shown in FIG. 1 (a), that is, the engaging arm 41 is in the engaging protrusion 20. It is set to be in contact with or just before contact.
By setting in this way, the outer cap C does not easily rotate from the set state (fastened state), and it is possible to prevent the cap from being inadvertently opened by a slight impact and to open the cap. Sometimes, the screw can be started smoothly so that the load at the time of initial movement of rotating the outer cap C does not suddenly increase.
Further, in the set state, the reduced diameter step portion 43 of the sealing ring 33 is lowered below the protrusion 23 of the outer cylinder 5.

When the two-agent mixing cap of the present embodiment filled with the second agent a and assembled in a set state is screwed into the container body A filled with the first agent, the mouth portion 1 inserts the outer cylinder 5. It is slightly expanded outward, and the protrusion 23 on the outer peripheral surface of the outer cylinder 5 expands in diameter so that it can be engaged with the reduced diameter step portion 43 of the sealing ring 33.
Therefore, the seal cannot be opened unless the seal ring 33 is removed, and the opening status can be easily confirmed visually, so that opening due to mischief or the like can be prevented.
Further, as the screwing progresses, the lower portion of the outer cylinder 5 exceeds the neck ring 3, the neck ring 3 tightens the inner circumference of the outer cylinder 5, and the two-agent mixing cap is fixed to the mouth portion 1 of the container body A.

In this embodiment, the two-agent mixed cap in which the inner cap B and the outer cap C are assembled in a set state is screwed into the container body A and attached, but the inner cylinder 6 of the inner cap B and the inner cylinder 6 are attached. It may be attached by a stopper such that the mouth portion 1 of the container body A is fitted to the outer cylinder 5.
Further, not only the first agent stored in the container body A closed by the two-agent mixed cap, but also the second agent a stored in the storage cylinder 10 of the inner cap B is the upper part of the outer storage cylinder portion 14. The upper inner peripheral surface of the pouring cylinder 16 is sealed by the seal cylinder portion 37 of the outer cap C, and the upper inner peripheral side of the inner storage cylinder portion 15 is in contact with the engaging cylinder portion 36, so that the sealed state is maintained. ing.

Next, in order to use the container equipped with the two-agent mixing cap of this embodiment, the outer cap C is rotated with respect to the inner cap B in the screwing direction [arrow direction in FIG. 4]. At that time, since the outer cylinder 5 of the inner cap B is tightened and fixed by the neck ring 3, the inner cap B does not rotate at the same time in the screwing direction of the container body A.
As described above, when the outer cap C starts to rotate, the engaging arm 41 and the engaging protrusion 20 are separated from each other, so that the rotation starts smoothly, and the engaging arm 41 comes into contact with the engaging protrusion 20 and engages. Then, the rotational force of the outer cap C is applied to the plug body 12 of the inner cap B via the ratchet mechanism.

At this time, since the second engaging protrusion 40 of the engaging portion 35 gets over the first engaging protrusion 21 of the tubular wall 18 and is tightly fitted to the inner peripheral surface of the tubular wall 18, the cylinder The shaped wall 18 is reinforced from the inside so that the rotational force of the outer cap C is easily transmitted to the plug body 12 via the ratchet mechanism, and a force for pulling up the plug body 12 upward is generated as the screw rotates.
As shown in FIG. 4, as the rotation of the outer cap C progresses, the thinning weakening portion 13 at the lower end of the storage cylinder 10 is finally broken by the rotational force and the pulling force applied to the plug body 12, and the storage cylinder 10 is opened. The second agent a separated into the outer storage cylinder portion 14 and the inner storage cylinder portion 15 and stored in the storage cylinder 10 begins to fall into the container body A, and the inner storage cylinder portion 15 of the storage cylinder 10 becomes a plug. Along with 12, the second agent a is completely pulled into the container body A as the second agent a completely falls into the container body A as the engagement portion 35 engaging with the tubular wall 18 pulls up and rises to complete the breakage of the thin-walled weakening portion 13. It is mixed with the first agent in.

At the same time, the reduced diameter step portion 43 of the sealing ring 33 engages with the protrusion 23 to prevent further ascent, the weakened connecting portion 32 breaks, and the sealing ring 33 is separated from the outer cap C and visually. You can see that it was opened.
When the second screw portion (female screw) 39 is screwed off from the second screw portion (male screw) 17 and the outer cap C is separated from the inner cap B, the inner storage cylinder portion 15 and the plug body 12 are removed together with the outer cap C. , The mixed content composed of the first agent and the second agent a mixed in the container body A can be injected from the opening of the injection cylinder 16 at the upper part of the outer storage cylinder portion 14.
In order to pour out the well-mixed contents, the outer cap C is screwed into the inner cap B again, the container body A is shaken well to mix, and then only the outer cap C is screwed off to mix the contents. The inner cap B can be unscrewed while the outer cap C is screwed by pouring out an object or by firmly grasping the outer cylinder 5 of the inner cap B from which the sealing ring 33 has been removed and turning it in the opening direction. , The mixed contents can be poured out from the mouth 1.

To attach the outer cap C to the inner cap B, the second screw portion (female screw) 39 of the screw cylinder portion 38 of the outer cap C with the inner storage cylinder portion 15 and the plug body 12 is attached to the injection cylinder of the inner cap B. All that is required is to apply it to the second screw portion (male screw) 17 of 16 and screw it. At that time, the seal cylinder portion 37 can seal the upper inner circumference of the pouring cylinder 16 and seal the mixed contents in the container body A.

In this embodiment, since there are a first screw portion, a second screw portion, and two screw portions, the first screw portion can be a reverse screw with respect to the second screw portion, or a detent mechanism can be provided. ..

In the two-agent mixed cap of the present invention, when the outer cap is screwed off from the inner cap, the thinned weakened portion at the lower end of the storage cylinder is broken, and the second agent stored in the storage cylinder falls into the container body. Therefore, it can be mixed with the first agent stored in the container body by a normal lid opening operation without performing a difficult operation.
In addition, since the entire thin-walled weakened part is surely broken, not only liquids but also powders, granules, jellies, solids, etc. as the second agent can be surely contained in the container body. Since it can be removed, it can be applied to a wide range of applications such as chemicals, cosmetics, and cleaning agents, in addition to foods and drinks and seasonings that are mixed and used immediately before use.
