Description

  The present invention relates to a two-substance mixing container.

Conventionally, a first storage part and a second storage part that are vertically adjacent to each other, a middle cap that threadably seals a first opening that communicates the first storage part and the second storage part, and an upper opening of the second storage part There has been proposed a container composed of a pouring cap that seals an opening to a base that is a portion, and a rotation transmission means that transmits the rotation of the pouring cap to an intermediate cap (see Patent Document 1). In this container, when the dispensing cap is rotated in the direction in which the middle cap is unscrewed, this rotation is transmitted to the middle cap, the middle cap is unscrewed from the first opening, and the first opening is opened. . When the first opening is opened, the first storage portion and the second storage portion communicate with each other through the opened first opening, so that the first content and the second content can be mixed. it can.
JP-A-11-91831

  However, when the above-described container is used, the middle cap falls into the first storage portion, so that the middle cap and the first storage portion collide when the container is used. Then, every time the container is used, a collision sound is generated, which causes discomfort to the user. In addition, if the middle cap collides with the first storage part, the inside of the first storage part may be damaged, and a situation in which the damage of the first storage part is mixed into the contents of the container may be considered. In particular, the latter problem becomes more apparent as the number of collisions between the middle cap and the first storage portion increases.

  The container of the present invention greatly contributes to improving the functionality of the container for mixing the two substances and its comfort by solving the above-described plurality of technical problems at once.

  One two-substance mixing container of the present invention has a mouth and neck formed at the top and a first container for storing the first substance, and is engaged and fixed to the mouth and neck, and covers the mouth and neck. An inner lid in which a through-hole communicating between the inside and the outside of the first container is formed, a second container in which a discharge port is formed at the top and a circulation port is formed in the bottom, and the second container A guide mechanism for guiding the movement between the lower position and the upper position. In addition, in the two-substance mixing container of the present invention, the upper surface of the inner lid and the bottom surface of the second container are in contact with each other at the lower position, so that the through-hole and the circulation port are In the process of closing and moving to the upper position, the upper surface of the inner lid and the bottom surface of the second container are separated from each other, so that the discharge port and the inner side of the first container are connected to the flow port and the It communicates through the through hole.

  If this two-component mixing container is employed, the through-hole and the circulation port are closed by contacting the top surface of the inner lid and the bottom surface of the second container at a position below the second container. The first substance stored in one container and the second substance stored in the second container are not mixed.

  Furthermore, since the inner lid is fixed to the first container, the inner lid does not fall into the first container and collide with the first container. On the other hand, since the through-hole is formed in the inner lid, the contents of the first container and the contents of the second container can be mixed without dropping the inner lid. For this reason, no collision noise is generated, and the first container, the inner lid, or the second container is damaged by the collision, and the contents of the first container, the inner lid, or the second container are mixed into the contents. Nor. In addition, by fixing the inner lid, once all the mixed contents are stored in the first container, the bottom surface of the second container is again in contact with the upper surface of the inner lid, It is also possible to contain the contents in the first container.

  According to the two-component mixing container of the present invention, the first substance stored in the first container and the second substance stored in the second container in the initial state can be held without mixing. In addition, since the container structure is not broken away or cut off during mixing, the contents of the first container, the inner lid, or the second container are not mixed. Furthermore, after mixing the contents of each container, no unpleasant collision sound is generated for the user each time it is used.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this description, common parts are denoted by common reference symbols throughout the drawings unless otherwise specified. In the drawings, the elements of the present embodiment are not necessarily shown to scale. In addition, in order to make each drawing easy to see, some symbols may be omitted.

<First Embodiment>
FIG. 1 is a cross-sectional view showing the state of the lower position of the second container 30 of the two-substance mixing container in one embodiment of the present invention, and FIG. 2 is a cross-sectional view showing the state of the upper position. FIG. 3 is an enlarged sectional view showing the inner lid 20 and the second container 30 in an enlarged manner. 4 is a perspective view showing the inner lid 20 from above, and FIG. 5 is a perspective view showing the second reservoir 60 of the second container 30 from below.

  A two-substance mixing container 100 shown in FIGS. 1 to 3 includes a first container 10, an inner lid 20, a second container 30, a bottomless cylindrical cover member 40, and a lid 50. In addition, as shown in FIGS. 1 and 3, the two-substance mixing container 100 has the second container 30 placed at a lower position (the position of the second container 30 in FIG. 1) and an upper position (the second container 30 in FIG. 2). A guide mechanism for guiding the movement between the first position and the second position. This guide mechanism combines the inner lid guide part 24, the second container guide part 72, the male screw part 73 constituting a part of the second container, and the female screw part 43 constituting a part of the cover member 40. It is a thing. Below, each structural member of the two-material mixing container 100 is demonstrated.

  First, as shown in FIG.1 and FIG.2, the 1st container 10 is provided with the 1st storage part 12 which stores the 1st substance while the mouth neck part 11 is formed in the upper part. A male screw portion 13 is formed on the outer periphery of the mouth and neck portion 11.

  As shown in FIGS. 1 and 4, the inner lid 20 is formed so as to cover the mouth-neck portion 11 of the first container 10. The inner lid 20 includes a through hole 21 that communicates the inside and the outside of the first container 10, and a female screw part 22 that is screwed into the male screw part 13 of the first container 10. The inner lid 20 is fixed to the first container 10 by screwing the female screw part 22 and the male screw part 13 of the first container 10. Furthermore, it is preferable that the inner lid 20 and the mouth-and-neck portion 11 have a rotation stop that prevents relative rotation. If such a rotation stop is provided, even if the cover member 40 described later is frequently rotated, the rotation of the inner lid 20 accompanying the rotation of the cover member 40 can be prevented. For this reason, it is possible to prevent loosening between the inner lid 20 and the first container 10.

  Further, the inner lid 20 further includes a convex portion 23 protruding upward from the lid portion 26, a cylindrical inner lid guide portion 24 erected upward from the outer periphery of the lid portion 26, and the lid portion 26. And a sealing cylinder 25 that is suspended from the outer periphery toward the inside of the first container 10. The seal cylinder 25 is closely fitted to the inner peripheral surface of the mouth / neck portion 11 of the first container 10. Thereby, the contents are prevented from leaking from the gap between the inner peripheral surface of the mouth-neck portion 11 of the first container 10 and the inner lid 20. In addition, in this embodiment, although the internal thread part 22 and the external thread part 13 of the 1st container 10 are being fixed by screwing, it is not limited to this. A known engaging means different from the screwing can be applied.

  The 2nd container 30 is provided with the bottomed cylindrical 2nd storage part 60 which stores the 2nd substance, and the guide member 70 which guides the movement of the lower position of the 2nd storage part 60, and the upper position.

  The second reservoir 60 shown in FIG. 5 has an opening 61 at the top thereof, and a circulation port 62 is formed at the bottom thereof. Moreover, the recessed part 64 fitted with the convex part 23 of the inner cover 20 is provided in the downward position. By fitting the convex portion 23 and the concave portion 64, the inner lid 20 and the second container 30 can be aligned with high accuracy. In addition, it is preferable that the convex part 23 and the recessed part 64 are tapered. If the convex portion 23 and the concave portion 64 are tapered, the convex portion 23 and the concave portion 64 can be easily fitted even if the relative position with respect to the inner lid 20 is slightly shifted when the second container 30 moves up and down. Can be combined. In particular, even when the vertical movement of the second container 30 is frequently repeated, or even when a slight physical impact is applied to the entire container, the positional relationship with the inner lid 20 at the lower position of the second container 30 It is possible to reduce the displacement to the extent that it does not affect the blockage of the mouth and neck portion 11. Moreover, it is preferable that the convex part 23 protrudes from the approximate center of the cover part 26. This is because, if the convex portion 23 protrudes from the approximate center of the lid portion 26, it is possible to prevent displacement in the rotational direction with the convex portion 23 as an axis. However, even when the convex portion 23 protrudes from the substantially end portion of the lid portion 26, by forming the plurality of convex portions 23, displacement in the rotation direction with the convex portion 23 as an axis is prevented. be able to.

  In addition, the guide member 70 of the second container 30 is fixed so as to cover the opening 61 by fitting a part of the guide member 70 into the opening 61 of the cylindrical second storage 60. A discharge port 71 that communicates the inside and the outside of 60 is provided. Further, the guide member 70 is provided at a substantially upper end portion of the second screw guide portion 72 that is slidably arranged with the inner lid guide portion 24, a male screw portion 73 that engages with the cover member 40, and the male screw portion 73. A protrusion 74 is formed, and a seal cylinder 75 is provided so as to be suspended inward from the lower surface of the upper plate on which the discharge port 71 is formed. This seal cylinder 75 is fitted in close contact with the inner peripheral surface of the opening 61 of the second reservoir 60. Thereby, the contents are prevented from leaking from the gap between the inner peripheral surface of the opening 61 of the second reservoir 60 and the guide member 70.

  The bottom surface of the second container 30 is in contact with the top surface of the inner lid 20 at the lower position. In particular, in the present embodiment, the bottom surface of the second container 30 and the top surface of the inner lid 20 are in pressure contact. As a result, the through-hole 21 of the inner lid 20 and the circulation port 62 of the second container 30 are closed in a state where the contents cannot flow in and out. For this reason, when the 2nd container 30 exists in a downward position in the unused stage, the 2nd substance stored by the 2nd container 30 does not mix in the 1st container 10. FIG. The pressure contact surfaces of the second container 30 and the inner lid 20 are provided with contact rings, packings, and the like, so that the occlusion can be further improved. Thus, by improving the blockage, it is possible to cope with changes in properties such as the viscosity of the contents and the presence or absence of a surfactant.

  On the other hand, once the second container 30 moves to the upper position, the upper surface of the inner lid 20 and the bottom surface of the second container 30 are separated in the process. As a result, the through-hole 21 of the inner lid 20 and the circulation port 62 of the second container 30 are released from the closed state. Therefore, in the process of moving the second container 30 to the upper position or in the upper position, the discharge port 71 of the second container 30 and the inside of the first container 10 are connected to the circulation port 62 and the inner lid of the second container 30. It communicates through 20 through-holes 21. Therefore, in this state, the second substance stored in the second container 30 is mixed into the first container 10, and the second substance stored in the first container 10 and the second container 30 is stored in the second container 30. Mix with the substance.

  In the present embodiment, the outer peripheral side surface of the second reservoir 60 of the second container 30 is the inner lid guide part 24 of the inner lid 20 when the second container 30 moves between the lower position and the upper position. Sliding in close contact with. For this reason, the contents can be prevented from leaking from the gap between the inner lid 20 and the second container 30. In order to prevent the contents from leaking through the gap between the inner lid 20 and the second container 30, it is preferable to mold the second storage portion 60 and the inner lid 20 by an injection molding method. This is because when the molding is performed by the injection molding method, a certain level of accuracy is maintained, so that the sealing performance between the second reservoir 60 and the inner lid 20 can be improved.

  The cover member 40 includes a cover 41 that surrounds the outer periphery of the second container 30 at a position below the second container 30, a protrusion 42 that is rotatably engaged with the outer periphery of the inner lid 20, and the second container 30. A female screw portion 43 that is threadably engaged with the male screw portion 73, and a protrusion 44 that is formed at a substantially upper end portion of the female screw portion 43 and engages with the protrusion 74 of the second container 30. . In the present embodiment, the second container 30 and the cover member 40 are fixed by engaging the protrusion 74 of the second container 30 and the protrusion 44 of the cover member 40 at a position above the second container 30. The As a result, the screwing of the male threaded portion 73 of the second container 30 and the female threaded portion 43 of the cover member 40 is hindered, so that the second container 30 does not go downward. With such a configuration, after the first substance stored in the first container 10 and the second substance stored in the second container 30 are mixed, the second container 30 does not move in its upper position. The user can determine at a glance that the first substance and the second substance are mixed. Note that the protrusion 74 of the second container 30 and the protrusion 44 of the cover member 40 are employed as fixing means for fixing the second container 30 and the cover member 40 above the second container 30. However, it may be fixed by other known means including a fixing means using a known bonding technique, for example.

  The lid 50 engages with the second container 30 so that the discharge port 71 can be opened and closed. The lid 50 is preferably configured to engage with the second container 30 by a hinge. In this case, even if the lid 50 is removed from the discharge port 71, the lid 50 and the second container 30 are engaged with each other, so that it is not necessary to store the lid 50 separately. Further, the lid 50 of the present embodiment is arranged such that the uppermost point A is substantially flush with the plane B formed by the upper opening 45 of the cover member 40 at a position below the second container 30. Here, “substantially the same plane” refers to a range of 5 mm or less from the same plane, preferably a plane having a distance (1 mm or less) that can be said to be extremely difficult to hold the lid 50. On the other hand, at the upper position of the second container 30, the uppermost point A is positioned above the plane B. For this reason, the lid 50 can be prevented from being accidentally opened at the lower position of the second container 30, while the lid 50 can be easily opened at the upper position of the second container 30. Can do. From the viewpoint of ergonomics, the uppermost point A of the lid is preferably 20 mm or more above the plane B formed by the upper opening 45. Moreover, it is preferable that the clearance gap between the upper surface outer periphery of the cover body 50 and the inner periphery of the upper side opening part 45 of the cover member 40 is a grade (8 mm or less (more preferably 3 mm or less)) which a human finger cannot enter.

  Next, the process of using the two-substance mixing container 100 will be described. FIG. 6 is a flowchart showing a process of using the two-substance mixing container 100.

  As shown in FIG. 6, first, the cover member 40 is rotated relative to the first container 10 (step S1). Then, the male screw portion 73 of the second container 30 that engages with the female screw portion 43 of the cover member 40 is screwed relative to the female screw portion 43 of the cover member 40. Thereby, the 2nd container 30 starts the movement to an upper position (step S2). By starting the movement of the second container 30 to the upper position, the through-hole 21 of the inner lid 20 and the circulation port 62 of the second container 30 are opened, and the discharge port 71 of the second container 30 and the inside of the first container 10 are opened. And communicate with each other through the circulation port 62 and the through-hole 21. Therefore, the second substance stored in the second container 30 is mixed into the first container 10 via the circulation port 62 and the through-hole 21, and the first substance and the second substance stored in the first container 10 are mixed. The substance is mixed (step S3). Further, when the second container 30 is moved to the upper position by continuing the rotation of the cover member 40, the protrusion 74 of the second container 30 and the protrusion 44 of the cover member 40 are engaged, and the second container 30 and the cover are engaged. The member 40 is fixed (step S4). Subsequently, the lid 50 that engages with the upper portion of the second container 30 is removed from the second container 30, and the discharge port 71 is opened (step S5). In this state, when the two-substance mixing container 100 is arranged so that the discharge port 71 is directed downward, in other words, the first container 10 is directed upward, the contents of the first container 10 are caused by gravity to pass through the through-hole 21 and the distribution port. 62 and discharge through the discharge port 71 (step S6).
