Description

  The present invention relates to a two-component mixing container suitable for applications such as adding an auxiliary agent to a main agent, and intends to mix two agents by a simple operation without causing separation waste. .

  As a two-component mixing container, two storage bodies filled with different types of contents are prepared and configured in two layers, and when used, one storage body is rotated to open an opening connected to both storage bodies. There is known a type in which the contents filled in one storage body are dropped toward the other storage body so as to mix the two agents.

In addition, as the two-component mixing container, a main chamber is provided with a sub chamber portion filled with an auxiliary agent inside the cap, and the bottom wall portion of the sub chamber portion is opened by closing the cap and stored in the main body portion. This type of container is also known to be applied not only to hair dyeing agents but also to tea and other beverages, and the demand will continue to increase in the future. It is expected (see Patent Document 1).

  Among the above two-component mixing containers, cap-type mixing containers are particularly demanding even when compared to two-component mixing containers that are composed of two layers because the structure is simple and compact. Although considered to be expensive, this two-component mixing container mixes the two agents for the first time by tearing and separating the annular band (belt having a stopper function) that prevents inadvertent rotation of the cap. In addition, the tearing operation is troublesome, and the annular belt is completely separated, so it is separately disposed of as separated waste. It is difficult to say that it is preferable from the viewpoint of reusing, and the improvement has been demanded.

  An object of the present invention is to propose a two-component mixing container that does not require an operation of removing an annular belt and does not generate separated waste.

The present invention has a mouth portion that opens at the top, a body portion that forms a storage space for contents in the lower portion thereof, and a mouth portion of the body portion, and the discharge port is opened by tightening a cap. A two-component mixing container comprising a subchamber for dropping the additive loaded inside into the storage space and adding the content to the contents in the storage space;
The cap has a tapered portion that tapers downward at the lower end portion thereof, and is integrally connected to the tapered portion via a thin piece that can be broken, and the cap is inadvertently positioned between the cap and the cap. Equipped with an annular band to prevent sliding
The annular band is a two-component mixing container characterized by having an inner diameter that fits on the outer peripheral wall of the cap as it slides toward the base of the cap, and at least about the lower end of the cap, The outer diameter is preferably slightly smaller than the inner diameter of the annular band.

  When the cap is tightened, the annular belt rides on the outer peripheral wall of the cap, and eventually the annular belt is fitted to the cap (the state of being embraced), so that separation garbage is generated. Also, no extra operation is required to remove the annular band.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a view schematically showing an embodiment of a two-component mixing container according to the present invention, FIG. 2 is a view showing a state where an auxiliary agent in a sub chamber is added, and FIG. 3 is a view showing a cap. It is the figure which expanded and showed the connection condition of the lower end part of this and an annular strip.

  In the figure, reference numeral 1 denotes a main body for storing contents (hereinafter referred to as a main agent). For example, a blow bottle is applied to the main body 1 and has a mouth 1a that opens at the top.

Reference numeral 2 denotes a sub chamber disposed in the mouth 1 a of the main body 1. The sub chamber part 2 has a short inner cylinder 2a positioned inside the mouth part 1a, and stands on a base 2b screwed to the outer peripheral wall of the mouth part 1a and a top wall 2b ₁ of the base 2b. A long outer cylinder 2c having a threaded portion on the outer peripheral wall, and a middle that hangs from the inner surface of the top wall of the cap 2f and is slidable along the inner peripheral wall of the inner cylinder 2a inside the long outer cylinder 2c A cylinder 2d, a cap held at the lower end of the intermediate cylinder 2d, a partition wall 2e forming the bottom of the intermediate cylinder 2d, and a cap screwed to the long outer cylinder 2c to cover the outer cylinder 2c together with the intermediate cylinder 2d The region divided by the intermediate cylinder 2d, the partition wall 2e, and the cap 2f is a loading space M for loading an auxiliary agent. A short cylindrical wall 2g for fitting and holding the partition 2e to the inner wall of the lower end of the intermediate cylinder 2d is provided upright from the outer end of the partition 2e, and a boundary (short cylinder wall) with the short cylindrical wall 2g is provided. At the lowermost end of 2g, there is formed a discharge port h that is closed by the inner wall of the inner cylinder 2a, but is opened by being removed from the inner cylinder 2a by sliding. The discharge port h is for discharging the auxiliary agent from the loading space M, and can be provided at least at one place, more preferably at multiple places around the intermediate cylinder 2d.

Reference numeral 3 denotes an annular belt provided at the lower end of the cap 2f. The annular band member 3 is shown as being integrally connected to a lower end of the cap 2f via a breakable thin piece 3a, the annular band member 3 is located between each other with the top wall 2b ₁ of the base 2b, Inadvertent sliding due to the rotation of the cap 2f is prevented. Further, 4 is a virgin band integrally connected to the lower end of the base 2b so as to be detachable via a connecting piece 4a (a thin piece continuous in the circumferential direction). The virgin band 4 is provided to grasp whether or not the container has been tampered with. The virgin band 4 is engaged with the convex portion of the mouth 1a of the main body 1 and is separated from the base 2b. It will not come out of the mouth 1a later.

As you crowded capped 2f in a two-agent mixing vessel comprising the arrangement, the cap 2f is descends toward the top panel wall 2b ₁ of the base 2b, the intermediate tube extending downwardly from the top panel wall of the cap 2f Accordingly 2d slides downward together with the partition wall 2e, and the discharge port h is opened. At the same time, the auxiliary agent present in the loading space M falls toward the main agent stored in the main body 1 and thereby the two The agent is mixed. The contents mixed with the two agents can be discharged by removing the base 2b from the mouth 1a of the main body 1.

On the other hand, the position change since located top panel wall 2b ₁ of the annular band member 3 is a lower end base 2b upon downward movement of the cap 2f does not occur, resulting in a thin piece of meat 3a is broken cap 2f is pushed strongly by the cap 2f As shown in FIG. 2, the entire annular band 3 is fitted to the outer peripheral wall of the cap 2f when the discharge port h is fully opened.

  When the auxiliary agent is added to the main agent according to the procedure as described above, the annular band 3 is in a state of being fitted to the cap 2f, so that no separation dust is generated, and the annular band 3 is removed when the cap 2f is screwed. There is no need for separate operations such as removal.

  The thin piece 3a that connects the cap 2f and the annular band 3 can be provided over the entire circumference of the annular band 3, but it can also be provided at a plurality of positions at intervals. It is not limited.

  Also, as shown in FIG. 3, the diameter of at least the lower end of the cap 2f is slightly smaller than the inner diameter of the annular band 3 so that it can ride on the outer peripheral wall of the cap 2f. It is preferable to form a tapered portion that tapers toward the end. In this case, as the cap 2f is lowered, the annular band 3 is guided by the small inner diameter portion (or tapered portion) at the lower end portion of the cap 2f and rides on the outer peripheral surface of the cap 2f. The relationship between the cap 2f and the annular band 3 is not limited to the above-described configuration for adjusting the outer diameter of the lower end of the cap 2f. The inner diameter of the annular band 3 is set to be larger than the outer diameter of the lower end of the cap 2f. The diameter may be slightly increased, and both diameters may be adjusted.

  The two-component mixing container shown in FIGS. 1 to 3 is merely an example of the embodiment according to the present invention. As the other mixing mechanism, for example, as described in the prior art, a mechanism in which a seal member for partitioning the sub chamber portion is opened by a cutting blade or the like as the cap descends may be applied. As long as the 3 and the cap 2f are provided, various known mechanisms can be employed as the mixing mechanism.

  It is possible to provide a two-component mixing container that does not require an operation for removing the annular band and that does not cause separation waste.

It is the figure which showed embodiment of the 2 agent mixing container according to this invention. It is the figure which showed the use condition of the 2 agent mixing container shown in FIG. It is the figure which expanded and showed the principal part of the 2 agent mixing container shown in FIG.
