Description

  The present invention relates to a mixing container suitable for mixing different types of materials in a single mixing space.

  In hair dyes and cosmetics, different types of materials (for example, main agent and auxiliary agent) are poured out from each container in a specified amount and mixed in a sealed container prepared separately. What you do is in circulation as a product.

By the way, in this type of product, especially when the contents react to generate gas when the contents are mixed, a degassing mechanism is required to avoid an increase in pressure in the mixing container. (For example, refer to Patent Document 1) In recent years, the structure tends to be complicated, and the cost of the mixing container itself cannot be avoided.

  The object of the present invention is to propose a new mixing container with a simplified structure.

The present invention was made in order to solve the above-described problem, and a cup that forms an accommodation space and a mixing space inside thereof by an annular peripheral wall and a bottom wall integrally connected to the lower end of the annular peripheral wall; A mixing container provided with a lid that is detachably fixed to the mouth of the cup and that holds the mouth in a sealed state,
The lid body includes a top wall facing the mouth opening of the cup, and a peripheral wall that is integrally connected to the edge of the top wall and engageable with the outer wall of the cup.
Between the lid and the cup, an elastic sheet that covers the entire area of the mouth of the cup is provided,
The elastic sheet is provided with a slit valve that opens as the pressure in the storage and mixing space increases,
The mixing container is characterized in that a through-hole communicating with the inside and outside of the lid is provided in the top wall of the lid.

  In the mixing container having the above-described configuration, it is preferable that the lid body is provided with a stopper that protrudes from the top wall and abuts against the opening portion of the slit valve when the slit valve is opened to regulate the degree of opening. In addition, it is desirable to provide a cylindrical body that is disposed on the lower surface of the top wall so as to surround the through hole and leave a very small gap between the elastic sheet and the elastic sheet.

  The top wall of the lid can have a dome-shaped cross-sectional shape that allows it to be inverted to the upper surface side and the lower surface side.

  The cup is provided with a plurality of vertical ribs arranged at an interval on the inner surface of the annular peripheral wall and inclined at an angle with respect to the axis of the cup, or at an angle with the annular peripheral wall facing inward. A plurality of convex portions that locally protrude can be provided.

  Since an elastic sheet is provided between the lid and the cup and the pressure increase in the container is released through a slit valve formed in the elastic sheet, the structure is not complicated.

  The degree of opening of the slit valve is restricted by the opening part of the slit valve coming into contact with a stopper provided on the top wall of the lid, so that the content can be prevented from flowing out through the valve.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 is an external perspective view of a mixing container according to the present invention, FIG. 2 is an exploded perspective view of FIG. 1, and FIG. 3 is a cross-sectional view of the mixing container shown in FIG.

  In the figure, reference numeral 1 denotes a cup for storing contents and mixing space M. The cup 1 includes an annular peripheral wall 1a and a bottom wall 1b integrally connected to the lower end of the annular peripheral wall 1a.

  Reference numeral 2 denotes a lid that is detachably fixed to the mouth 1c of the cup 1 by screws or undercuts and holds the mouth 1c in a sealed state. The lid 2 includes a top wall 2 a facing the mouth opening of the cup 1 and a peripheral wall 2 b that is integrally connected to an edge of the top wall 2 a and engageable with the mouth outer wall of the cup 1.

  Reference numeral 3 denotes an elastic sheet (packing-shaped) sandwiched between the lid 2 and the cup 1 (the protruding end of the mouth portion 1c). The elastic sheet 3 covers the entire area of the mouth portion 1c of the cup 1, and is provided with a slit valve 3a that opens as the pressure in the storage / mixing space M increases.

  4 is a through hole provided in the top surface wall 2a of the lid body 2 and communicates with the inside and outside of the top surface wall 5a. The cylindrical body 5 has a front end portion (lower end portion) that forms a very slight gap t between the elastic sheet 3.

  Reference numeral 6 denotes a stopper formed as an example of a cylindrical shape formed on the lower surface of the top wall 2a of the lid 2. When the slit valve 3a is opened, the stopper 6 comes into contact with the tip (lower end) of the stopper 6 to regulate the degree of opening of the slit valve 3a. As shown, a notch 6a is formed to facilitate passage through the pressurized gas.

  Further, 7 is a vertical rib provided at the lower part of the peripheral wall 1 a of the cup 1. A plurality of the vertical ribs 7 are provided at intervals along the periphery thereof, and exerts a function of promoting the mixing of the contents when a shaking motion is added to the mixing container. Further, the vertical rib 7 also exhibits a function that can effectively reduce the blocking phenomenon in which the cups 1 are stacked and cannot be separated from each other during so-called stacking.

  The mixing container having the above-described structure has a simple structure in which the elastic sheet 3 having the slit valve 3a is disposed between the lid 2 and the cup 1, and can be efficiently manufactured and reduced in manufacturing cost. There will be no rise.

  Further, the opening degree of the slit valve 3a is not only restricted by the stopper 6 as shown in FIG. 5, but the through hole 4 is surrounded by the cylindrical body 5, so that the mixing of the contents is promoted in the container. Even if a shaking motion is applied, the content does not leak through the through hole 4.

  FIG. 6 is a view showing another example of the mixing container according to the present invention. In this example, the longitudinal rib 7 is made longer and inclined with respect to the axis of the cup 1 with an angle θ. By providing the vertical rib 7 with the angle θ, the contents can be efficiently mixed.

FIG. 7 is a view showing another example of the mixing container according to the present invention. In this example, a plurality of convex portions 8 are provided by projecting the annular peripheral wall 1a of the cup 1 locally at an angle θ ₁ toward the inside, and the radial dimension at that portion is the central portion of the cup 1 in the longitudinal direction. It is molded to have a small diameter.

  In the mixing container having such a configuration, the container can be easily grasped and the contents can be efficiently mixed.

  FIGS. 8A to 8C are views showing still another example of the mixing container according to the present invention. In the present invention, the top wall 2a of the lid body 2 can also have a dome-shaped cross section, and in this case as well, as shown in FIG. 8 (b), even if the pressure in the container rises, the slit valve 3a Since the degree of opening is restricted, leakage of the contents is suppressed and efficient mixing becomes possible.

Especially to remove the lid 2 an elastic sheet 3 during cleaning or the like of the container it is possible to invert the origin 2a ₁ the boundary as shown in FIG. 8 (c) simply by the cross-sectional shape forming a dome it can.

  As shown in the embodiment, the elastic sheet 3 can be sandwiched and fixed between the mouth portion 1c of the cup 1 and the lid 2, but the elastic sheet 3 is attached to the inner surface of the lid 2 in advance. However, this point is not limited.

  It is possible to provide a mixing container having a simplified structure and having no risk of liquid leakage during the mixing operation.
