Description

[Technical field]

[0001] The present invention relates to a mixing vessel. [Background technology]

[0002] Conventionally, as shown in Patent Document 1 below, for example, a mixing container has been known which comprises a bottomed, cylindrical first container in which a first agent is contained, a second container which has a container section in which a second agent is contained and which has a communication port formed therein communicating with the inside of the first container and which is attached to the mouth of the first container, a cap which is removably screwed onto the mouth of the first container and covers the upper opening of the second container, and a closure member which blocks communication between the inside of the first container and the communication port, the communication port opening downward, the closure member extending in the vertical direction and connected to the container section via a breakable weakened portion, and the upper end of the closure member being connected to the top wall portion of the cap in a state in which its relative rotation in the circumferential direction is restricted. When the cap of this mixing container is rotated relative to the first container in the loosening direction, the closing member rotates with it, breaking the weakened portion and opening the communication port, causing the second agent in the storage portion to drop from the communication port into the first container and mix with the first agent. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2022-58010 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when the first and second agents are stirred in the first container so that the resulting mixture becomes homogeneous, it is necessary to attach the cap to the opening of the first container again.

[0005] The present invention provides a mixing container that can improve the operability of mixing a first agent and a second agent in a first container to obtain a homogeneous mixed agent. [Means for solving the problem]

[0006] A mixing container according to one embodiment of the present invention comprises a first container having a bottomed cylindrical shape and a body that is elastically deformable and that contains a first agent, a second container having a storage section that stores a second agent and has a communication port formed therein that communicates with the inside of the first container and is attached to the mouth of the first container, and a blocking member that blocks communication between the inside of the first container and the communication port, wherein the communication port opens downward, and the blocking member comprises a cover plate whose front and back surfaces face in the vertical direction and that is connected to the storage section via a breakable weakened section and that releasably blocks the communication port, and a pressable protrusion that protrudes downward from the underside of the cover plate and is located within the body of the first container.

[0007] The closing member protrudes downward from the underside of the cover plate closing the communication port and has a pressable projection located inside the body of the first container, so that when the body of the first container formed to be elastically deformable is pressed radially inward, the pressable projection is pressed radially by the inner circumferential surface of the elastically deformed body, breaking the weakened portion and opening the communication port. This causes the second agent in the second container to drop from the communication port into the first container and mix with the first agent. In the above process, since the second agent in the second container is mixed with the first agent in the first container without opening the first container to the outside, after this mixing, the first agent and the second agent can be quickly stirred in the first container without performing any other operation, for example by shaking the mixing container, so that the resulting mixture is homogeneous. Therefore, the operability of mixing the first agent and the second agent in the first container to obtain a homogeneous mixture can be improved.

[0008] The first container may have an outer circumferential surface, at a portion radially opposed to the pressed protrusion, formed with a recess recessed radially inward.

[0009] A recess that recesses radially inward is formed on the outer peripheral surface of the body of the first container in the portion radially opposite the pressed protrusion.Therefore, when the pressed protrusion is pressed radially inward and when the mixed agent is poured out from inside the first container, the recess can be pressed radially inward, which reliably breaks the weakened portion and stabilizes the pouring behavior. Since a recess is formed on the outer peripheral surface of the body of the first container, the position of the pressurized protrusion within the first container can be easily identified by the recess, and the inner peripheral surface of the body of the first container can be brought closer to the pressurized protrusion, so that the pressing force applied to the body of the first container can be kept low when the pressurized protrusion is pressed radially.

[0010] The body of the first container may have a flattened shape having a long axis and a short axis that intersect each other on a central axis of the first container when viewed in a plan view from above and below, and the recess may be provided in a portion of the body of the first container that faces in a short axis direction along the short axis.

[0011] Since the recess is provided in a portion of the body of the first container facing the minor axis direction, i.e., a portion extending in the major axis direction along the major axis, when the recess is pushed radially inward, the body of the first container can easily be elastically deformed radially inward.

[0012] The storage section may include a first storage tube provided above the mouth of the first container and having an inner diameter equal to or greater than the inner diameter of the mouth of the first container, and a second storage tube inserted into the mouth of the first container, and a lower end opening of the second storage tube may be the communicating port.

[0013] Since the storage portion is equipped with the first storage tube and the second storage tube, a large internal volume of the storage portion can be ensured, and the pressed protrusion can be easily positioned within the body of the first container. Effect of the Invention

[0014] According to one aspect of the present invention, it is possible to improve the operability of mixing the first agent and the second agent in the first container to obtain a homogeneous mixture. [Brief description of the drawings]

[0015] [Figure 1] FIG. 2 is a longitudinal sectional view of a mixing container shown as one embodiment, as viewed from a minor axis direction. [Diagram 2] FIG. 2 is a longitudinal cross-sectional view of a mixing vessel shown as one embodiment, taken along a longitudinal axis. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, a mixing container according to one embodiment of the present invention will be described with reference to the drawings. 1 and 2, the mixing container 1 according to this embodiment includes a bottomed cylindrical first container 11, a second container 12, and a closing member 13. The first container 11, the second container 12, and the closing member 13 are made of a synthetic resin material.

[0017] Hereinafter, the central axis of the first container 11 will be referred to as the container axis O, the direction along the container axis O will be referred to as the vertical direction, the direction intersecting the container axis O when viewed from the vertical direction will be referred to as the radial direction, and the direction going around the container axis O will be referred to as the circumferential direction. The side of the bottom 11a of the first container 11 along the vertical direction will be referred to as the lower side, and the side of the mouth 11b of the first container 11 along the vertical direction will be referred to as the upper side.

[0018] The first agent X1 is contained in the first container 11. The first container 11 is configured by connecting a mouth portion 11b, a shoulder portion 11c, a body portion 11d, and a bottom portion 11a in this order from top to bottom. A male screw portion is formed on the outer peripheral surface of the mouth portion 11b. The shoulder portion 11c extends radially inward as it extends upward, and the body portion 11d extends straight in the vertical direction. The body portion 11d is formed so as to be elastically deformable in the radial direction.

[0019] In the illustrated example, the first container 11, except for the mouth portion 11b, has a flat shape having a major axis and a minor axis that intersect with each other on the container axis O in a plan view seen from above and below. Hereinafter, in the plan view, the direction along the major axis is referred to as major axis direction L1, and the direction along the minor axis is referred to as minor axis direction L2. The body portion 11d of the first container 11 is formed so as to be elastically deformable at least in the minor axis direction L2 among the radial directions.

[0020] The second agent X2 is contained in the second container 12. The second container 12 is attached to the mouth portion 11b of the first container 11. The second container 12 has a storage portion 14 in which a communication port 12a communicating with the inside of the first container 11 is formed. The housing portion 14 includes a first housing cylinder 14a and a second housing cylinder 14b. The first housing cylinder 14a and the second housing cylinder 14b are formed in a cylindrical shape and are disposed coaxially with the axis O of the container.

[0021] The first housing cylinder 14a is provided above the mouth 11b of the first container 11, and has an inner diameter equal to or larger than the inner diameter of the mouth 11b of the first container 11. The outer diameter of the first housing cylinder 14a is the same as the size of the minor axis direction L2 of the body 11d of the first container 11. A cap 14e is attached to the upper end of the first housing cylinder 14a. The cap 14e seals the upper end opening of the first housing cylinder 14a.

[0022] The second accommodating tube 14b is inserted into the mouth 11b of the first container 11. The upper end of the second accommodating tube 14b is in liquid-tight contact with the upper end of the mouth 11b of the first container 11. This seals the inside of the mouth 11b of the first container 11. The lower end of the second accommodating tube 14b is located in the shoulder 11c of the first container 11. The lower end opening of the second accommodating tube 14b that opens downward serves as a communication port 12a that communicates with the inside of the first container 11. The lower end of the second accommodating tube 14b may be located in the mouth 11b of the first container 11.

[0023] The lower end of the first housing tube 14a and the upper end of the second housing tube 14b are connected via an annular step 14c whose front and back surfaces face the up-down direction. The lower surface of the step 14c abuts against the upper opening edge of the mouth 11b of the first container 11. A female threaded tube 14d extending downward is formed on the lower surface of the step 14c at a portion located radially outward from the mouth 11b of the first container 11. The female threaded tube 14d is screwed into the mouth 11b of the first container 11.

[0024] The closing member 13 includes a cover plate 13b and a pressed projection 13c, and blocks communication between the inside of the first container 11 and the communication port 12a. The closing member 13 is formed integrally with the storage portion 14 of the second container 12.

[0025] The cover plate 13b is formed in a plate shape with the front and back surfaces facing in the vertical direction. The cover plate 13b is connected to the storage portion 14 via a breakable weakened portion 13a, and closes the communication opening 12a in an openable manner. In the illustrated example, the outer peripheral surface of the cover plate 13b is connected to the inner peripheral surface of the communication opening 12a via the weakened portion 13a. The weakened portion 13a extends continuously around the entire circumference.

[0026] The pressed projection 13c projects downward from the lower surface of the cover plate 13b, and at least its lower end is located inside the body portion 11d of the first container 11. The vertical position of the pressed projection 13c is determined by the lower surface of the step portion 14c abutting against the upper opening edge of the mouth portion 11b of the first container 11.

[0027] The pressed projection 13c is configured by a first plate 13d whose front and back surfaces face the long axis direction L1 and a second plate 13e whose front and back surfaces face the short axis direction L2, which cross on the container axis O, forming a cross shape when viewed from the top and bottom. The first plate 13d is located at the center of the body 11d of the first container 11 in the long axis direction L1, and the second plate 13e is located at the center of the body 11d of the first container 11 in the short axis direction L2. The first plate 13d and the second plate 13e are each provided over almost the entire radial length on the underside of the cover plate 13b.

[0028] A recess 11e is formed on the outer circumferential surface of the body portion 11d of the first container 11 at a portion radially opposed to the pressed projection 13c, the recess 11e being recessed radially inward.

[0029] The recess 11e has a curved shape that protrudes toward the inside in the radial direction in a vertical cross section. The recess 11e has an elliptical shape that is long in the circumferential direction in a front view from the outside in the radial direction. The recess 11e is formed in the body 11d of the first container 11 so that the outer peripheral surface is recessed toward the inside in the radial direction and the inner peripheral surface is curved and bulges toward the inside in the radial direction. The deepest part of the recess 11e, which is located at the innermost radial direction, faces the lower end edge of the pressed protrusion 13c in the radial direction. The recess 11e faces the lower part of the pressed protrusion 13c in the radial direction, and protrudes downward and on both sides in the circumferential direction with respect to the lower part of the pressed protrusion 13c in a front view from the outside in the radial direction.

[0030] The recess 11e is provided in a portion of the body 11d of the first container 11 facing the short axis direction L2. The recess 11e faces the side surface of the first plate 13d in the short axis direction L2. One recess 11e is provided in the body 11d of the first container 11. This ensures that the weakened portion 13a can be easily broken when the lower portion of the pressed projection 13c is pressed in the short axis direction L2. Note that the recesses 11e may be provided one at a time at positions facing each other in the short axis direction L2.

[0031] In the above configuration, with the inside of the first container 11 kept sealed and not open to the outside, when a finger is placed against the recess 11e and the body 11d of the first container 11 is pressed inward in the short axis direction L2, the lower part of the pressed protrusion 13c is pressed in the short axis direction L2 by the inner surface of the elastically deformed body 11d, as shown by the two-dot chain line in Figure 2, causing the weakened portion 13a to break and the communication opening 12a to open.

[0032] At this time, the side surface of the first plate 13d of the pressed projection 13c is pressed toward one side in the short axis direction L2, so that the pressed projection 13c is tilted so that its lower portion is located on one side in the short axis direction L2 and its upper portion is located on the other side in the short axis direction L2, and the weakened portion 13a is successively broken from the end portion on the other side in the short axis direction L2 toward the end portion on one side in the short axis direction L2 while detouring toward the long axis direction L1. Note that the position where the breakage starts in the weakened portion 13a may be changed as appropriate. As a result, the second agent X2 in the second container 12 falls from the communication port 12a into the first container 11 and is mixed with the first agent X1. Thereafter, the mixing container 1 is shaken or the like to agitate the first agent X1 and the second agent X2 in the first container 11 so that the resulting mixture becomes homogeneous.

[0033] Then, after removing the second container 12 from the mouth 11b of the first container 11, a dispenser having, for example, a valve member or the like is attached to the mouth 11b of the first container 11, and a finger is placed on the recess 11e to press the body 11d of the first container 11 inward in the minor axis direction L2, thereby increasing the internal pressure of the first container 11 to open the valve member and dispense the mixed agent from the discharge hole. The discharger may have a pump mechanism.

[0034] As described above, according to the mixing container 1 of this embodiment, the closing member 13 protrudes downward from the lower surface of the cover plate 13b closing the communication port 12a and has the pressed projection 13c located in the body 11d of the first container 11, so that when the body 11d of the first container 11 formed to be elastically deformable is pressed radially inward, the pressed projection 13c is pressed radially by the inner peripheral surface of the elastically deformed body 11d, breaking the weakened portion 13a and opening the communication port 12a. As a result, the second agent X2 in the second container 12 falls from the communication port 12a into the first container 11 and is mixed with the first agent X1.

[0035] In the above process, since the second agent X2 in the second container 12 is mixed with the first agent X1 in the first container 11 without opening the inside of the first container 11 to the outside, after this mixing, the first agent X1 and the second agent X2 can be stirred quickly in the first container 11, for example by shaking the mixing container 1, without performing any other operation, so that the resulting mixture becomes homogeneous. Therefore, the operability of mixing the first agent X1 and the second agent X2 in the first container 11 to obtain a homogeneous mixture can be improved.

[0036] A recess 11e that is recessed radially inward is formed on the outer peripheral surface of the body 11d of the first container 11 in the portion radially opposite the pressed protrusion 13c. Therefore, when the pressed protrusion 13c is pressed radially inward and when the mixed agent is poured out from inside the first container 11, the recess 11e can be pressed radially inward, so that the weakened portion 13a can be reliably broken and the pouring mode can be stabilized.

[0037] Since a recess 11e is formed on the outer peripheral surface of the body 11d of the first container 11, the position of the pressed protrusion 13c inside the first container 11 can be easily identified by the recess 11e, and the inner peripheral surface of the body 11d of the first container 11 can be brought closer to the pressed protrusion 13c, so that the pressing force applied to the body 11d of the first container 11 when the pressed protrusion 13c is pressed radially can be kept low.

[0038] Since the recess 11e is provided in a portion of the body 11d of the first container 11 facing the short axis direction L2, i.e., in a portion extending in the long axis direction L1, when the recess 11e is pressed radially inward, the body 11d of the first container 11 can be easily elastically deformed radially inward.

[0039] Since the storage portion 14 is equipped with the first storage tube 14a and the second storage tube 14b, a large internal volume of the storage portion 14 can be ensured and the pressed protrusion 13c can be easily positioned within the body portion 11d of the first container 11.

[0040] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0041] For example, the first container 11 may be formed in a cylindrical shape over its entire length in the vertical direction. The body 11d of the first container 11 may be formed, for example, in a rectangular cylindrical shape extending in the vertical direction. The outer peripheral surface of the body portion 11d of the first container 11 does not necessarily need to have the recess 11e formed thereon. The pressed protrusion 13c may be formed, for example, in a rod shape extending in the vertical direction. The first agent X1 and the second agent X2 may be, for example, a liquid, a solid, or a fluid, and may be in the same state or different states. After obtaining the mixed agent in the first container 11 and removing the second container 12 from the mouth portion 11b of the first container 11, the mixed agent may be poured out from the mouth portion 11b without attaching a dispenser to the mouth portion 11b of the first container 11. The dispenser may not have a valve member, and may have a foaming member that foams when the liquid mixed agent passes toward the discharge hole.

[0042] As long as the pressed protrusion 13c does not interfere with the inner surface of the second accommodating tube 14b when it is pressed radially, thereby preventing the weakened portion 13a from breaking, the weakened portion 13a and the communicating port 12a may be provided, for example, in the middle portion in the vertical direction within the second accommodating tube 14b. The front and back surfaces of the cover plate 13b may be inclined with respect to the horizontal direction perpendicular to the up-down direction.

[0043] In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described embodiments and the above-described variations may be combined as appropriate. [Explanation of symbols]
