  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the two-component mixing container 10 of this embodiment has a bottomed cylindrical container body 12, and a cylindrical outlet 14 having a small diameter at the upper end of the container body 12. Are formed integrally, and a male thread 16 is formed on the outer surface of the outlet 14. The container body 12 is, for example, a plastic bottle.

  A cap 18 made of synthetic resin is screwed onto the outlet 14. The cap 18 is provided with a top surface portion 22 that closes the outlet 14, and in the center of the top surface portion 22, a cylindrical shape that passes through the outlet 14 from the lower surface of the top surface portion 22 and reaches the inner upper portion of the container body 12. The storage chamber 20 is integrally provided. The peripheral part of the top surface part 22 is located slightly outside the outlet 14 and is provided with a cylindrical side part 24 that covers the outlet 14. On the inner peripheral surface of the side surface portion 24, a female screw 26 that is screwed into the male screw 16 of the outlet 14 is formed. Between the side surface portion 24 and the storage chamber 20, a short cylindrical mounting portion 28 that is watertightly attached to the inner peripheral surface of the outlet 14 is provided integrally with the top surface portion 22.

  The upper end portion of the storage chamber 20 that communicates with the top surface portion 18 serves as an upper end opening portion 20a, and at a position slightly lower than the upper end opening portion 20a, the disc-shaped pressing portion 30 is parallel to the upper end opening portion 20a. Is provided integrally with the inner peripheral surface of the storage chamber 20. Between the storage chamber 20 and the pressing part 30, a flexible part 32 formed of a thin wall is provided in an annular shape around the pressing part 30. The flexible part 32 extends downward as the distance from the pressing part 30 increases, and the cross section is formed in a trapezoidal cylindrical shape. That is, the flexible portion 32 and the pressing portion 30 are formed in a convex shape upward as shown in FIG. When a force is applied to the pressing portion 30 from above, the convex shape is reversed and deformed into a concave shape, that is, a downward convex shape as shown in FIG. The pressing part 30 and the flexible part 32 partition the lower part of the storage chamber 20 and the upper end opening part 20a in a liquid-tight state.

  A rod-like extruded portion 34 is integrally formed at the approximate center of the lower surface 30a of the pressing portion 30. The push-out portion 34 is inserted through the storage chamber 20 and extends downward, and the distal end 34a of the push-out portion 34 is slightly above the lower end opening 20b of the storage chamber 20 and the peripheral edge of the lower end opening 20b. It is located eccentrically by a part of the. For this reason, the pushing part 34 is inclined with respect to the insertion direction of the storage chamber 20. The thickness of the extruding part 34 is formed to be slightly thinner as it approaches the tip end part 34 a of the extruding part 34. The shape of the distal end portion 34 a is formed so as to be cut by a plane parallel to the lower end opening 20 b of the storage chamber 20.

  A film member 36 is adhered and stuck to the lower end opening 20b of the storage chamber 20 to close the storage chamber 20 in a liquid-tight manner. The adhesion strength of the film member 36 is such that the material does not peel even when the material is loaded in the state in which the material is accommodated in the accommodation chamber 20, liquid or gas does not enter the accommodation chamber 20 from the outside, and the extrusion portion 34 is Set to a certain range where it can be easily peeled off by pressing.

  A lid sheet 38, which is a lid member that covers the upper end opening 20 a of the storage chamber 20, is attached to the top surface portion 22 of the cap 18, and covers the storage chamber 20, the pressing portion 30, and the flexible portion 32.

  Next, the usage method of the 2 component mixing container 10 of this embodiment is demonstrated. The two-component mixing container 10 is used, for example, with tea. Water is put into the container body 12, and an appropriate amount of powdered tea is put into the storage chamber 20 of the cap 18. The female screw 26 of the cap 18 is screwed onto the male screw 16 of the outlet 14 of the container main body 12 and sealed to carry and store.

  When drinking tea from the two-component mixing container 10, the lid sheet 38 is peeled off from the top surface portion 22 of the cap 18 to expose the pressing portion 30. Next, when the pressing portion 30 is pressed with a finger, the flexible portion 32 is deformed and the pressing portion 30 moves downward as shown in FIG. 1B, and the pushing portion 34 also moves downward accordingly. To do. The distal end portion 34 a of the pushing portion 34 pushes down the edge portion of the film member 36 attached to the lower end opening 20 b of the storage chamber 20 and peels it from the storage chamber 20. Then, the film member 36 is opened, and the powdered tea in the storage chamber 20 falls into the container body 12. In this state, the container body 12 is shaken to mix powdered tea with water to make tea, and the cap 18 is removed to drink tea from the outlet 14.

  The flexible part 32 may be returned to its original state by elastic deformation or may not be returned. The opened film member 36 may be removed from the storage chamber 20 by hand. This improves the appearance.

  According to the two-component mixing container 10 of this embodiment, the film member 36 is peeled off by a simple operation of storing water and powdered tea in a separated state and pressing the pressing portion 30 when drinking. You can make powdered tea by dropping it into water and mixing it. In order to peel off the film member 36, a special jig is not particularly required, and an operation such as changing the direction of the cap is unnecessary, and the film member 36 can be performed with one touch while the cap 18 is closed. It can be mixed before opening the cap 18, and even if the container is shaken for stirring, it does not spill tea and is safe.

  Since the extruding portion 34 is provided obliquely, the pressing force of the pressing portion 30 of the cap 18 efficiently acts as a pressing force for peeling from the lower end opening portion 20b of the peripheral edge portion of the film 36, and easily opens. Can do. Since the film member 36 is peeled off and opened, the opening area can be made larger than the opening by perforation. Since the film member 36 is not damaged, no broken pieces or the like are generated, there is no fear that foreign matters are mixed into the tea, and the appearance is not unsightly. Since the peeled film member 36 is attached to the lower end opening 20 at a portion opposite to the portion where peeling is started, there is no fear of dropping. Since the film member 36 is opened obliquely from the peripheral edge, the powdered tea falls easily without clogging.

  Before mixing, since the lid sheet 38 is affixed to the top surface portion 22, the storage chamber 20, the pressing portion 30, and the flexible portion 32 are hidden, and the appearance is neat. Also, inadvertent mixing operations are prevented. The lid sheet 38 may be covered with an injection molded product. If the lid sheet 38 is made of an easily breakable member such as paper, and the pressing part 30 is pushed in from the top of the lid sheet 38 during mixing, mixing can be easily performed before and after mixing. A preventive effect can be imparted. Further, in the process of filling powdered tea, the cap 18 is set upside down, the powdered tea is filled into the storage chamber 20 and the film member 36 is stuck, so that the productivity is excellent. And since the powdered tea is melted just before drinking, you can drink freshly made tea, and the flavor feels fresh and delicious.
