Description

[Technical field]

[0001] The present invention relates to a two-liquid mixing container and a spraying container equipped with the two-liquid mixing container and a sprayer. [Background technology]

[0002] For example, some cosmetics and hair dyes produce a certain effect by mixing two types of liquids. When mixing such liquids, for example, two containers each containing two types of liquid are prepared, and the liquid is transferred from one container to the other container, and the two liquids are mixed in the transferred container.

[0003] When two such containers are used, there is a risk that the positions of the mouths of one container may become misaligned while the liquid is flowing from the mouth of the other container, causing the liquid to overflow.

[0004] On the other hand, Patent Document 1 shows a mixing container in which the mouths of two containers are connected to each other and a plug that has been blocking one of the containers is removed when the containers are connected. With this mixing container, the plug is removed after the mouths are connected to each other and the liquid medicine does not overflow, so the above-mentioned problem can be prevented. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 2-144576 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in such a two-container configuration, the amount of resin used in the container increases, and mixing often requires a lot of work. In addition, in a mixing container like the one in Patent Document 1, the removed plug remains in the container. For this reason, users who are not familiar with such mixing containers may mistakenly believe that a part that should not come off has come off.

[0007] The present invention has an objective to solve such problems, and to provide a two-liquid mixing container that can store two types of liquid separately in one container before use and mix them when used, and in which a detached stopper will not remain inside the container, as well as a spray container equipped with this two-liquid mixing container and a sprayer. [Means for solving the problem]

[0008] The present invention relates to a container body having a bottom, a body, and a mouth, the body having a narrowed portion, the body having a first space located between the bottom and the narrowed portion and containing a first liquid agent, and a second space located between the narrowed portion and the mouth and containing a second liquid agent, A plug portion that is inserted into the narrowed portion and blocks communication between the first space and the second space; A mounting portion that is detachably mounted to the mouth portion and has an opening for introducing a second liquid agent; The two-liquid mixing container is provided with a connection portion that connects the plug portion and the mounting portion and has a communication port that communicates between the opening and the second space.

[0009] It is preferable to provide a lid portion which closes the opening and is held unremovably on the mounting portion.

[0010] It is preferable that the container body be provided with a film extending from the portion in the body where the first space is located to the narrowed portion, or extending from the portion in the body where the second space is located to the narrowed portion, and partially covering the outside of the container body.

[0011] It is preferable that the plug portion is elastically deformable and has a plate-like portion extending radially outward with a tip portion contacting the inner circumferential surface of the narrowed portion.

[0012] The present invention also provides a spray container comprising the above-mentioned two-liquid mixing container, and a sprayer attached to the mouth portion from which the attachment portion has been removed, for spraying the first liquid agent and the second liquid agent mixed in the container body together with air in the container body, The ejector is also an ejection vessel having a liquid inlet located in the first space and an air inlet located in the second space. Effect of the Invention

[0013] The container body in the two-liquid mixing container of the present invention has a narrowed portion in the body, and the inside of the body has a first space located between the bottom and the narrowed portion and in which the first liquid agent is contained, and a second space located between the narrowed portion and the mouth and in which the second liquid agent is contained. When the stopper body part is inserted inside the narrowed portion, communication between the first space and the second space is prevented. Therefore, before use, the first liquid agent and the second liquid agent can be contained separately in one container body. In addition, since the stopper body part is connected to the mounting part via the connection part, when the mounting part is removed from the mouth part during use, the stopper body part is pulled up via the connection part, and the first space and the second space are thereby connected to each other, allowing the first liquid agent and the second liquid agent to be mixed. The pulled up stopper body part is removed from the container body together with the mounting part and the connection part, so that the stopper body part does not remain in the container body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, a two-liquid mixing container 10A according to a first embodiment of the two-liquid mixing container of the present invention will be described with reference to the drawings. In this specification and the like, the up-down direction is the direction along the illustrated central axis O (the central axis of the container body 1 described later). The radial direction is the direction perpendicular to the central axis O in a plane perpendicular to the central axis O, and the circumferential direction is the direction rotating around the central axis O in this plane.

[0016] The two-liquid mixing container 10A of this embodiment includes a container body 1, a film 2 (see the partially enlarged view of FIG. 1), an attached cap 3A, and a lid body (lid portion) 4. The container body 1 contains, for example, a cosmetic or hair dye, and two types of liquid agents (a first liquid agent L1 and a second liquid agent L2 in this embodiment) that exert a predetermined effect when mixed together.

[0017] In this embodiment, the container body 1 has a plate-shaped bottom 1a that is elliptical in plan view, a body 1b that is connected to the outer edge of the bottom 1a, and a cylindrical mouth 1c that is provided above the body 1b.

[0018] A narrowed portion 1d is provided in the body 1b by recessing the body 1b toward the inside in the radial direction, slightly above the center in the vertical direction. Here, the part of the body 1b located below the narrowed portion 1d is referred to as the lower body 1e, and the part of the body 1b located above the narrowed portion 1d is referred to as the upper body 1f. The space located inside the lower body 1e is referred to as the first space S1, and the space located inside the upper body 1f is referred to as the second space S2. The upper body 1f of this embodiment has a smaller diameter and a lower height than the lower body 1e, and the capacity of the second space S2 is smaller than that of the first space S1. The first space S1 contains a first liquid agent L1, and the second space S2 contains a second liquid agent L2.

[0019] The lower body 1e of this embodiment is a portion that extends upward from the outer edge of the bottom 1a of the body 1b as shown in Fig. 1 (a portion that has an elliptical cylindrical shape that extends in the same shape as the outer edge of the bottom 1a). The narrowed portion 1d extends upward from the upper end of the lower body 1e while decreasing in diameter in an arc shape, then extends upward (extends to become cylindrical about the central axis O), and then extends linearly while increasing in diameter as it extends upward. The upper body 1f is a portion that extends upward from the upper end of the linearly expanding portion of the narrowed portion 1d, then extends linearly while decreasing in diameter as it extends upward, and connects to the lower end of the mouth 1c.

[0020] An engagement portion 1g, which is male-threaded in this embodiment, is provided on the outer circumferential surface of the mouth portion 1c.

[0021] The container body 1 of this embodiment is formed of synthetic resin, and has a laminated structure in which a plurality of layers are superimposed as shown in the partially enlarged view of FIG. 1. At least one of the plurality of layers is used that has a barrier property against various gases such as oxygen and light. In this embodiment, a material having a function of suppressing the outflow of gases evaporated from the first liquid agent L1 and the second liquid agent L2 to the outside of the container body 1 and the inflow of oxygen from the outside into the container body 1 is used. In forming the container body 1 of such a laminated structure, for example, a cylindrical laminated parison in which a plurality of synthetic resin materials are laminated may be shaped into the illustrated shape by blow molding (extrusion blow molding), or a laminated preform may be formed by injection molding a plurality of molten synthetic resin materials, and the laminated preform may be shaped into the illustrated shape by stretch blow molding.

[0022] Furthermore, the container body 1 of this embodiment is flexible, and when force is applied to the trunk portion 1b, it can be squeezed.

[0023] The film 2 partially covers the outside of the container body 1. The film 2 of this embodiment is heat-shrinkable when heated, and can be attached to the outer circumferential surface of the container body 1 as shown in the figure by heating the film 2 while covering the periphery of the second space S2. As shown in the partially enlarged view of FIG. 1, the film 2 of this embodiment covers from the upper part of the upper body 1f where the diameter is reduced to the part extending along the central axis O of the narrowed part 1d. That is, if the part covered by the film 2 is only the part of the upper body 1f that has the same outer diameter in the vertical direction, there is a risk that the film 2 will shift in the vertical direction relative to the container body 1, but since the film 2 of this embodiment extends to the part where the narrowed part 1d is provided, it is possible to prevent the film 2 from shifting in position relative to the container body 1.

[0024] The film 2 of this embodiment also has a function of having a barrier property (light-shielding property) against light. That is, since the film 2 covers the outside of the second space S2, it is possible to suppress deterioration due to light for the second liquid agent L2 contained in the second space S2. Since the container body 1 of this embodiment has a layer having a barrier property against light laminated thereon, it is possible to further suppress deterioration due to light. Note that the first liquid agent L1 in this embodiment is not so susceptible to deterioration due to light. For this reason, in this embodiment, the portion covered by the film 2 is limited to the outside of the second space S2, thereby reducing the amount of the film 2 used and suppressing costs. Note that the film 2 may have a function other than light-shielding property (for example, a barrier property against oxygen, etc.). In addition, both the container body 1 and the film 2 may have such a barrier property, or only one of them may have it. In addition, in cases where the barrier property can be obtained only by the container body 1, the film 2 may not be provided.

[0025] The mounting cap 3A includes a plug body 3a that is inserted into the narrowed portion 1d. The plug body 3a in this embodiment includes a cylindrical wall 3b that is cylindrical, and an inclined top wall 3c that is connected to the upper end of the cylindrical wall 3b and extends upward while linearly decreasing in diameter. The outer peripheral surface of the cylindrical wall 3b is in liquid-tight contact with the inner peripheral surface of the portion of the narrowed portion 1d that extends along the central axis O, thereby preventing communication between the first space S1 and the second space S2.

[0026] The mounting cap 3A also includes a mounting portion 3d that is detachably attached to the mouth portion 1c. The mounting portion 3d in this embodiment includes a cylindrical outer peripheral wall 3e that surrounds the mouth portion 1c, a female-threaded engaged portion 3f provided on the inner peripheral surface of the outer peripheral wall 3e, a top wall 3g that extends radially inward from the upper end of the outer peripheral wall 3e, and an opening 3h that penetrates the center of the top wall 3g. The engaged portion 3f is screwed into the engaging portion 1g, so that the mounting cap 3A is held in the mouth portion 1c.

[0027] Furthermore, the mounting cap 3A has a connection portion 3j that extends downward from the inner edge of the mouth portion 1c and connects to the outer edge of the inclined top wall 3c. The connection portion 3j in this embodiment extends downward from the inner edge of the mouth portion 1c while decreasing in diameter, and then extends downward in a state where the diameter is approximately the same as the outer edge of the inclined top wall 3c, and is generally cylindrical. The connection portion 3j is provided with a communication port 3k that penetrates it. The communication port 3k communicates the opening 3h with the second space S2. In this embodiment, multiple communication ports 3k are provided at intervals in the circumferential direction.

[0028] The mounting cap 3A also includes outward claw-shaped portions 3m that extend upward from the top wall 3g and have tips that protrude radially outward.

[0029] The cover 4 has a plate-shaped top wall 4a that covers the upper part of the outward claw 3m. The outer edge of the top wall 4a has an inward claw 4b that is located radially outside the outward claw 3m, extends downward, and has a tip that protrudes radially inward. The inward claw 4b engages with the outward claw 3m, and when the inward claw 4b and the outward claw 3m are engaged, the cover 4 is held in the mounting cap 3A in an undetachable manner. The top wall 4a has a cylindrical seal wall 4c that is located radially inside the outward claw 3m and extends downward. When the cover 4 is held by the mounting cap 3A, the outer circumferential surface of the seal wall 4c is in liquid-tight contact with the inner circumferential surface of the outward claw 3m.

[0030] In such a two-liquid mixing container 10A, the first liquid L1 is injected into the container body 1 before the mounting cap 3A is attached. As a result, the first liquid L1 is contained in the first space S1. Then, the stopper body part 3a and the connecting part 3j are inserted into the mouth part 1c, the engaged part 3f is screwed into the engaging part 1g, and the stopper body part 3a is inserted into the narrowed part 1d. In the state where the stopper body part 3a is inserted into the narrowed part 1d, as described above, the outer peripheral surface of the cylindrical wall 3b contacts the inner peripheral surface of the narrowed part 1d in a liquid-tight manner, so that the first space S1 can be closed. In addition, in order to reliably insert the stopper body part 3a into the narrowed part 1d, for example, a rod-shaped tool may be inserted into the inside of the connecting part 3j to push the inclined top wall 3c downward.

[0031] After the plug portion 3a is inserted into the narrowed portion 1d, the second liquid agent L2 is injected from the opening 3h. As a result, the second liquid agent L2 passes through the communication port 3k and is contained in the second space S2. Then, the inward claw portion 4b of the lid body 4 is engaged with the outward claw portion 3m, so that the lid body 4 is held in an undetachable manner relative to the mounting cap 3A. That is, the lid body 4 is not accidentally or intentionally removed, so that only the second liquid agent L2 is not poured out from the two-liquid mixing container 10A. In addition, when the lid body 4 is held by the mounting cap 3A, the outer peripheral surface of the seal wall 4c is in liquid-tight contact with the inner peripheral surface of the outward claw portion 3m, so that the second liquid agent L2 does not overflow from the two-liquid mixing container 10A.

[0032] When the first liquid L1 and the second liquid L2 are mixed, the mounting cap 3A is rotated in a direction in which the screwing of the engaging portion 1g and the engaged portion 3f is released. Then, as shown in FIG. 2, when the mounting cap 3A is lifted from the container body 1, the stopper body portion 3a inserted in the narrowed portion 1d is also lifted, and the second liquid L2 contained in the second space S2 flows into the first space S1, so that the first liquid L1 and the second liquid L2 can be mixed in the first space S1. After that, when the engaging portion 1g and the engaged portion 3f are screwed together, the first space S1 is closed again by the stopper body portion 3a, so that even if the container body 1 is shaken in this state to sufficiently mix the first liquid L1 and the second liquid L2, the liquid will not flow into the second space S2. Note that, depending on the type of liquid, bubbles may be generated from the first liquid L1 and the second liquid L2 when the container body 1 is shaken, but these bubbles will not flow into the second space S2 due to the stopper body portion 3a.

[0033] As described above, according to the two-liquid mixing container 10A of the present embodiment, when the stopper body part 3a is inserted into the narrowed part 1d as shown in Fig. 1, the first liquid agent L1 and the second liquid agent L2 can be stored separately in the container body 1. In addition, since the first liquid agent L1 and the second liquid agent L2 can be mixed simply by removing the attached cap 3A, it is also excellent in terms of operability. Furthermore, when the attached cap 3A is removed from the container body 1, the stopper body part 3a is also removed from the container body 1, so the stopper body part 3a does not remain in the container body 1.

[0034] The two-liquid mixing container 10A of this embodiment can be used as a spray container by removing the mounting cap 3A and then attaching a sprayer 20 shown in Fig. 3 to the container body 1. The sprayer 20 has a liquid inlet 27 and an air inlet 28, which will be described later, and sprays the liquid agent introduced from the liquid inlet 27 in a foamed state using air introduced from the air inlet 28.

[0035] The ejector 20 of this embodiment includes a pipe 21, a hood 22, a cylinder 23, a foaming member 24, a check valve 25, and a nozzle cap 26. A liquid inlet 27 is provided at the tip of the pipe 21, and an air inlet 28 is provided inside the hood 22. The nozzle cap 26 includes an engaged portion 26a that is female-threaded like the engaged portion 3f, and a nozzle 26c that includes a spray outlet 26b at its tip. The foaming member 24 has a fine mesh, and can foam the liquid agent and air by passing through the mesh.

[0036] Such a sprayer 20 can be attached to the container body 1 by inserting the pipe 21 into the inside of the mouth portion 1c and screwing the engaged portion 26a into the engaging portion 1g. At this time, the liquid inlet 27 is located in the first space S1, and the air inlet 28 is located in the second space S2.

[0037] When the body portion 1b is squeezed, the pressure inside the container body 1 rises because the air passage connecting the container body 1 to the outside world is closed by the check valve 25, and as a result, the first liquid agent L1 and the second liquid agent L2 mixed in the first space S1 are introduced into the cylinder 23 from the liquid inlet 27 through the pipe 21. Also, the air inside the container body 1 is introduced into the cylinder 23 from the air inlet 28. Then, the liquid agent and the air mixed in the cylinder 23 pass through the foaming member 24 and foam, and are further ejected in a foamed state from the ejection port 26b through the nozzle 26c.

[0038] However, if the air introduced from the air inlet 28 contains bubbles generated from the first liquid L1 and the second liquid L2, the ratio of the liquid and the air in the cylinder 23 changes, and the foaming may not be performed as intended, and the foam quality may be impaired. On the other hand, if the first liquid L1 and the second liquid L2 are stirred in a state in which the first space S1 is closed by the stopper body part 3a as described above, the generated bubbles do not flow into the second space S2, so that it is possible to prevent a problem in which bubbles are taken in from the air inlet 28 located in the second space S2 and the foam quality is changed. In addition, since the container body 1 of this embodiment has a narrowed portion 1d, even if the container body 1 is tilted as shown in FIG. 3, the liquid mixed in the first space S1 does not flow beyond the narrowed portion 1d into the second space S2 in normal use. Therefore, it is possible to prevent a problem in which the mixed liquid is taken in from the air inlet 28 and the foam quality is changed.

[0039] Next, a two-liquid mixing container 10B according to a second embodiment of the present invention will be described. Note that the same reference numerals will be used in the drawings to designate parts common to the two-liquid mixing container 10A described above, and detailed descriptions thereof will be omitted.

[0040] The two-liquid mixing container 10B of this embodiment includes the above-mentioned container body 1, film 2, and lid 4, and includes an attachment cap 3B instead of the attachment cap 3A.

[0041] The mounting cap 3B includes a plug body 3n to be inserted into the narrowed portion 1d. The plug body 3n of this embodiment includes a cylindrical wall 3p having a smaller diameter than the narrowed portion 1d, and an inclined top wall 3q that is connected to the upper end of the cylindrical wall 3p and extends while linearly decreasing in diameter as it moves upward. The outer peripheral surface of the cylindrical wall 3p is provided with a plate-like portion 3r that is elastically deformable, extends radially outward, and has a tip that contacts the inner peripheral surface of the narrowed portion 1d in a liquid-tight manner. The plug body 3n of this embodiment includes a total of four plate-like portions 3r spaced apart in the vertical direction. The plate-like portion 3r located at the bottom has a larger diameter than the other three, and contacts the inner peripheral surface of the portion extending in an arc shape from the upper end of the lower body portion 1e in the narrowed portion 1d. By providing multiple plate-shaped portions 3r in this manner, even if one plate-shaped portion 3r is not in sufficient contact with the narrowed portion 1d, the other plate-shaped portions 3r can prevent communication between the first space S1 and the second space S2.

[0042] The mounting cap 3B also includes a connecting portion 3s that connects the plug portion 3n and the mounting portion 3d. The connecting portion 3s in this embodiment extends downward from the inner edge of the mouth portion 1c while decreasing in diameter, and connects to the outer edge of the inclined top wall 3q, and is generally cylindrical. The connecting portion 3s is provided with a communication port 3t that passes through the connecting portion 3s and communicates the opening 3h with the second space S2. In this embodiment, multiple communication ports 3t are provided at intervals in the circumferential direction.

[0043] In such a two-liquid mixing container 10B, when the plug portion 3n is inserted into the narrowed portion 1d as shown in Fig. 4, the tip portion of the plate-like portion 3r comes into liquid-tight contact with the inner peripheral surface of the narrowed portion 1d. Therefore, the two-liquid mixing container 10B can also accommodate the first liquid agent L1 in the first space S1 and the second liquid agent L2 in the second space S2 in the same manner as the above-mentioned two-liquid mixing container 10A.

[0044] In order to mix the first liquid agent L1 and the second liquid agent L2 in the two-liquid mixing container 10B, the mounting cap 3B is rotated in a direction in which the engaging portion 1g and the engaged portion 3f are released from the screwing engagement. When the mounting cap 3B is lifted up from the container body 1, the stopper portion 3n inserted in the narrowed portion 1d is also lifted up as shown in Fig. 5, and the second liquid agent L2 contained in the second space S2 flows into the first space S1, so that the first liquid agent L1 and the second liquid agent L2 can be mixed in the first space S1.

[0045] In this manner, in the two-liquid mixing container 10B of this embodiment, when the stopper body part 3n is inserted into the narrowed part 1d as shown in Fig. 4, the first liquid agent L1 and the second liquid agent L2 can be stored separately in the container body 1. Moreover, the first liquid agent L1 and the second liquid agent L2 can be mixed simply by removing the mounting cap 3B. Furthermore, when the mounting cap 3B is removed from the container body 1, the stopper body part 3n is also removed from the container body 1, so the stopper body part 3n does not remain in the container body 1.

[0046] Although not shown in the drawings, the liquid agent can also be ejected in a foamed state using the above-mentioned ejector 20 in the two-liquid mixing container 10B.

[0047] Although one embodiment of the present invention has been described above, the present invention is not limited to the specific embodiment, and various modifications and changes are possible within the scope of the spirit of the present invention described in the claims unless otherwise specifically limited in the above description. For example, the configuration of the above-mentioned embodiment can be appropriately added or deleted, and the configuration of one embodiment can be applied to another embodiment. Furthermore, the effects of the above-mentioned embodiment are merely examples of the effects resulting from the present invention, and do not mean that the effects of the present invention are limited to the above-mentioned effects.

[0048] For example, the above-mentioned ejector 20 foams and ejects the liquid, but the ejector may be one that ejects the liquid stored in the container body 1 in liquid form. The two-liquid mixing containers 10A and 10B are not limited to those to which such an ejector is attached, and may be ones to which a pouring cap having a pouring outlet for pouring the liquid to the outside is attached. The container body 1 is not limited to the above-mentioned container with a laminated structure, and may be a single-layer container. The film 2 may extend from the part of the body 1b where the first space S1 is located to the narrowed part 1d so as to cover the outside of the first space S1. [Explanation of symbols]
