Description

  The present invention relates to a mixing container capable of mixing a first content and a second content stored independently at the time of dispensing.

  As this type of mixing container, for example, by removing the overcap screwed to the mouth of the bottle, the first contents contained in the bottle and the inner plug fitted in the mouth of the bottle are accommodated. There is known a mixing container that can be poured out while mixing the second contents (see Patent Document 1).

The mixing container will be described in detail. The inner plug includes a cylindrical outer cylinder, a top-cylindrical inner cylinder that is disposed inside the outer cylinder, and is integrally connected to the lower end of the outer cylinder. , Is composed of. The inner stopper configured as described above is fitted in the mouth of the bottle. In addition, an annular storage chamber is secured between the outer cylinder and the inner cylinder of the inner plug, and the second content is stored in the storage chamber.
In addition, a cup-shaped cap that covers the upper portion of the inner cylinder is attached to the inner plug. At this time, the cap is in a non-contact state with respect to the inner cylinder, and allows the second content to flow to the top wall portion of the inner cylinder.

  An overcap is screwed into the mouth portion into which the inner plug is fitted. At this time, a puncture portion protruding downward is formed on the lower surface of the top wall portion of the overcap. When the overcap is screwed, this puncture part punctures the cap that covers the inner plug and the top wall of the inner cylinder of the inner plug at the same time, and the tip penetrates the top wall and reaches the inside of the inner cylinder It is supposed to be.

  According to the mixing container configured as described above, the first content and the second content are not mixed before the overcap is removed. Here, when the overcap is removed for use, the puncture portion is pulled out, so that the top wall portion of the inner cylinder and the cap are opened. Therefore, the first content and the second content can be poured out while being mixed.

European Patent Application No. 0534909

  However, since the conventional mixing container has a structure in which the puncture portion punctures the cap and the top wall portion of the inner cylinder when the overcap is screwed, there is a possibility that dripping or the like may occur during puncture. Therefore, when the overcap is removed and used, this squeezing or the like may interfere with the pouring, and the pouring performance may be lowered.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a mixing container that can be efficiently poured out while mixing the first content and the second content. is there.

In order to achieve the above object, the present invention provides the following means.
(1) A mixing container according to the present invention is a mixing container that can be poured out while mixing a first content and a second content, and a container body that contains the first content therein, An inner cap attached to the inside of the mouth portion of the container main body, and an overcap that is detachably attached to the mouth portion and covers the inner stopper, and the inner stopper accommodates the second content. An inner plug body having a storage chamber, and a closing member that closes the upper portion of the storage chamber, and the inner plug body can close the storage chamber by bringing an upper end portion into contact with the closing member, An inner cylinder that communicates with the interior of the container body to pour out the first contents, an outer cylinder that surrounds the inner cylinder from the outside in a radial direction, and the outer cylinder and the inner cylinder The storage chamber is formed between the two cylinders and can be reversed and deformed in the container axial direction with the connecting portion with the outer cylinder as a base point. An annular bottom wall portion that allows the inner cylinder to move in the container axial direction, and the overcap has a push-down portion that pushes down the inner cylinder during mounting to reversely deform the bottom wall portion. It is characterized by.

  In the mixing container according to the present invention, the inner stopper in which the second content is accommodated in the accommodation chamber is mounted inside the mouth portion of the container body in which the first content is accommodated. At this time, the closing member closes the upper portion of the storage chamber formed in the inner plug main body and is in contact with the upper end portion of the inner cylinder. Therefore, the storage chamber is closed (sealed) while the second content is stored inside. Therefore, it is possible to efficiently perform the operation of mounting the inner plug without paying special attention to the second content.

Next, an overcap is attached to the mouth of the container body.
When attaching the overcap, the push-down portion applies a downward force to the inner cylinder. Then, the bottom wall part which connects the outer cylinder and the inner cylinder reversely deforms with the connecting portion with the outer cylinder as a base point, and moves the inner cylinder downward along the container axis. Therefore, the upper end portion of the inner cylinder also moves downward, and the upper end portion that is abutted and shielded by the closing member is opened. At this time, since the upper end part of the inner cylinder is shielded by the push-down part, there is no possibility that the second content in the storage chamber flows inside the inner cylinder. Therefore, at this time, the first content and the second content are in a state of being accommodated independently. Thus, the production of the mixing container is completed when the overcap is attached.

  And when using a mixing container, an overcap is removed from the opening | mouth part of a container main body. Then, since the push-down portion that has shielded the upper end portion of the inner cylinder is detached from the mouth portion together with the overcap, the inside of the container main body and the inside of the storage chamber are in communication with each other. Therefore, the second content can be mixed when the first content is poured out through the inner tube of the inner plug. In this way, the first content and the second content can be poured out while being mixed.

In particular, the mixing container of the present invention is different from the conventional container in which the first contents and the second contents are mixed by puncturing the top wall portion of the cap or inner cylinder. The first content and the second content are mixed by the downward movement. For this reason, there is no risk of wrinkling during puncturing, and the first content and the second content can be efficiently poured out while being mixed.
Moreover, after the bottom wall portion is once reversed and deformed, it is difficult for an upward force to act on the bottom wall portion. Therefore, after the overcap is removed, the bottom wall portion is reversed and deformed in the reverse direction and does not return to its original state. Therefore, there is a low possibility that the inner cylinder moves upward and the upper end is again shielded by the closing member. Therefore, also in this respect, it is difficult to prevent the dispensing.
Further, when the inner plug is attached to the mouth of the container body, the storage chamber for storing the second contents is closed, so that the operation of attaching the inner plug can be performed efficiently, and the production efficiency is improved. Improvement can be achieved.

(2) The mixing container according to the present invention is the mixing container according to the present invention, wherein a through hole is formed in the upper end portion of the inner cylinder, and the through hole is spaced at an equal interval around the container axis. A plurality of them are formed.

  In the mixing container according to the present invention, a plurality of through holes are formed at equal intervals around the container axis. Therefore, when the container body is tilted and poured out, no matter which direction the container body is tilted, unevenness occurs. The second content can be mixed with the first content. Moreover, the outflow amount of the second content can be easily set by designing the number and size of the through holes according to the viscosity of the content and the target mixing ratio. Therefore, the reliability as a mixing container can be improved.

(3) The mixing container according to the present invention is the above mixing container according to the present invention, wherein a projecting portion protruding radially inward is formed on the inner peripheral surface of the inner cylinder, and the push-down portion is the overcap At the time of mounting, it is characterized in that it is formed in a cylindrical shape or a columnar shape whose tip comes into contact with the protruding portion while abutting the inner peripheral surface of the inner cylinder and the inner surface of the spout of the closing member.

In the mixing container according to the present invention, when the overcap is mounted, the push-down portion moves downward in contact with the inner peripheral surface of the inner cylinder and the inner surface of the outlet of the closing member, and then the tip contacts the protruding portion. To do. Therefore, the push-down portion can apply a downward force to the inner cylinder through the protrusion while shielding the upper end portion of the inner cylinder, and can push down the inner cylinder.
In particular, since the protrusion is used, the inner cylinder is moved downward while shielding the upper end of the inner cylinder with a simple configuration in which the push-down part is not formed into a complicated shape but is formed into a cylindrical shape or a column shape. be able to. Therefore, the shape of the overcap can be simplified, leading to cost reduction.

  According to the mixing container of the present invention, the first content and the second content can be efficiently poured out while being mixed. In addition, since the storage chamber in which the second contents are stored is closed when the inner plug is mounted on the mouth of the container body, the inner plug can be mounted efficiently and the manufacturing efficiency can be improved. Can be achieved.

  Hereinafter, an embodiment of a mixing container according to the present invention will be described with reference to FIGS. 1 to 4. As shown in FIG. 1, the mixing container 1 of the present embodiment is a container that can be poured out while mixing the first contents W1 and the second contents W2, and has a bottomed cylindrical shape having a mouth portion 10. The container body 2, the inner stopper 3, and the overcap 4 are provided.

FIG. 1 is a longitudinal sectional view of the mixing container 1 immediately before the overcap 4 is mounted in the manufacturing stage. The central axes of the respective components are located on a common axis. In the present embodiment, this common axis is referred to as a container axis O, and a direction orthogonal to the container axis O is a radial direction, and a direction around the container axis O is a circumferential direction. Further, along the container axis O direction, the mouth 10 side of the container body 2 is the upper side, and the bottom side of the container body 2 is the lower side.
Moreover, the 1st content W1 and the 2nd content W2 are contents, such as a liquid form, a paste form, a granular form, and a powder form, for example, and there is no limitation regarding the form.

  The container body 2 is a bottomed cylindrical container having a mouth portion 10, and the first content W1 is accommodated therein. On the outer peripheral surface of the mouth portion 10, a male screw portion 10a into which the female screw portion 40a of the overcap 4 is screwed is formed. Further, the distal end portion of the mouth portion 10 is a reduced diameter portion 11 whose outer diameter is reduced, and a claw portion 11a protruding radially outward is formed on the outer peripheral surface of the reduced diameter portion 11 in an annular shape. ing.

The inner plug 3 is a member that is attached to the inside of the mouth portion 10 of the container body 2 and includes a storage chamber R that stores the second contents W2 as shown in FIGS. 1 and 2. FIG. 2 is a longitudinal sectional view of the inner plug 3.
The inner plug 3 will be described in detail. The inner plug 3 includes an inner plug body 20 and a closing member 30. The inner plug body 20 is integrally formed of an inner cylinder 21, an outer cylinder 22, a bottom wall portion 23, a peripheral wall cylinder 24, and a top wall portion 25.

  The inner cylinder 21 is a cylinder member that communicates with the inside of the container main body 2 to pour out the first contents W1 to the outside, and is movable in the container axis O direction by the reverse deformation of the bottom wall portion 23. The outer cylinder 22 is a cylindrical member disposed so as to surround the inner cylinder 21 from the outer side in the radial direction, and when the inner plug 3 is attached to the container body 2, the upper end portion thereof is the inner diameter of the reduced diameter portion 11. It comes in contact with the peripheral surface. The bottom wall portion 23 is an annular member that connects the lower end portion of the outer cylinder 22 and the lower end portion of the inner cylinder 21, and the storage chamber R in which the second content W <b> 2 is stored between both the cylinders 21 and 22. It is formed. Further, the bottom wall portion 23 can be inverted and deformed in the direction of the container axis O with the lower end portion of the outer cylinder 22 (the connecting portion with the outer cylinder 22) as a base point. It can be moved in the container axis O direction.

  The peripheral wall cylinder 24 is a member disposed so as to surround the reduced diameter portion 11 of the container main body 2 from the outside in the radial direction, and is connected to the upper end portion of the outer cylinder 22 by the top wall portion 25. Further, an engagement claw portion 24 a that is engaged with the claw portion 11 a is formed in an annular shape on the inner peripheral surface of the peripheral wall cylinder 24. Then, by engaging this engaging claw portion 24a with the claw portion 11a formed in the reduced diameter portion 11, the inner plug 3 can be mounted inside the mouth portion 10 of the container.

  By the way, a through hole 26 is formed in the upper end portion of the inner cylinder 21 to communicate the inner side and the outer side of the inner cylinder 21. Here, one side of the through hole 26 opens to the outer peripheral surface side of the inner cylinder 21, and the other side opens to the inner peripheral surface side of the inner cylinder 21. A plurality of the through holes 26 are formed around the container axis O at equal intervals. In the present embodiment, the case where eight through holes 26 are formed every 45 degrees around the container axis O will be described as an example. However, the number of through holes 26 is not limited to eight and may be set freely.

  Further, on the inner peripheral surface of the inner cylinder 21, a protruding portion 27 that protrudes inward in the radial direction is formed at a distance from the through hole 26 toward the bottom wall portion 23. Four projections 27 are formed around the container axis O every 90 degrees. However, the number of the protrusions 27 is not limited to four and may be set freely. Moreover, you may form cyclically | annularly over the perimeter of the internal peripheral surface of the inner cylinder 21. FIG.

The closing member 30 is fitted between the outer cylinder 22 and the inner cylinder 21 so as to close the upper portion of the storage chamber R. At this time, the closing member 30 is fixed to the outer cylinder 22 but is merely in contact with the inner cylinder 21. In addition, a spout 31 that communicates with the inside of the inner cylinder 21 is formed at the center of the closing member 30.
Further, in a stage before the overcap 4 is attached, one side of the through hole 26 formed in the inner cylinder 21 (the side opened to the outer peripheral surface side of the inner cylinder 21) is shielded by the closing member 30. It has become. That is, the upper end surface and the outer peripheral surface of the upper end portion of the inner cylinder 21 are in contact (close contact) with the closing member 30. More specifically, the inner diameter of the spout 31 of the closing member 30 is formed to be equal to the inner diameter of the inner cylinder 21, and a downward stepped portion is formed on the lower surface of the spout 31. The upper end surface of the upper end portion of 21 is in contact with the container axis O direction, and the inner peripheral surface of the closing member 30 and the outer peripheral surface of the upper end portion of the inner cylinder 21 are in contact with each other in the radial direction.

On the other hand, as shown in FIG. 3, at a stage after the inner cylinder 21 has moved downward due to the attachment of the overcap 4, one side of the through hole 26 is accommodated through the annular groove 32 formed in the lower end portion of the closing member 30. It communicates within R. That is, one side of the through-hole 26 is designed to be shielded before the inner cylinder 21 is moved downward and to be communicated with the storage chamber R after the downward movement.
3 is an enlarged cross-sectional view of the state where the overcap 4 is attached from the state of FIG.

  As shown in FIGS. 1 and 3, the overcap 4 is a cap that is detachably attached to the mouth portion 10 and covers the inner plug 3 when attached. The overcap 4 includes a peripheral wall tube 40 that surrounds the periphery of the mouth portion 10 of the container body 2 and a top wall portion 41 that covers an upper portion of the peripheral wall tube 40. On the inner peripheral surface of the peripheral wall tube 40, a female screw portion 40a that is screwed into the male screw portion 10a is formed. The overcap 4 can be attached to the mouth portion 10 of the container by screwing the female screw portion 40a with the male screw portion 10a formed in the mouth portion 10.

  Further, the lower surface of the top wall portion 41 shields the other side of the through hole 26 (the side opened to the inner peripheral surface side of the inner cylinder 21) when the overcap 4 is mounted (the inner periphery of the upper end portion of the inner cylinder 21). The inner cylinder 21 is pushed down while being in contact with the surface to allow one side of the through hole 26 to communicate with the storage chamber R, and as shown in FIG. A push-down portion 42 that communicates with the inside of the inner cylinder 21 is formed. 4 is an enlarged cross-sectional view of the state where the overcap 4 is removed from the state of FIG.

  The push-down portion 42 of the present embodiment protrudes downward from the top wall portion 41 and is formed in a cylindrical shape that can contact the inner peripheral surface of the inner cylinder 21. As shown in FIG. 3, the push-down portion 42 contacts the inner peripheral surface of the inner cylinder 21 and the inner surface of the spout 31 of the closing member 30 when the overcap 4 is mounted, and the other of the through holes 26. The tip is in contact with the protrusion 27 while shielding the side. That is, the push-down portion 42 applies a downward force to the inner cylinder 21 via the protrusion 27.

  Further, in the overcap 4 of the present embodiment, an annular ring portion 43 is formed on the lower surface of the top wall portion 41 so as to project the push-down portion 42 from the outside in the radial direction. The ring portion 43 comes into contact with the upper surface of the top wall portion 25 of the inner plug main body 20 when the overcap 4 is attached. The ring portion 43 is not essential and may not be provided.

Next, a procedure for assembling and manufacturing the above-described mixing container 1 will be briefly described.
First, as shown in FIG. 1, the inner plug 3 in which the second content W2 is accommodated in the accommodation chamber R is mounted inside the mouth portion 10 of the container body 2 in which the first content W1 is accommodated. Specifically, the inner plug 3 is pushed in while the outer cylinder 22 is inserted inside the mouth portion 10, and the engagement claw portion 24 a of the peripheral wall cylinder 24 is engaged with the claw portion 11 a of the reduced diameter portion 11. Thereby, the inner plug 3 can be mounted in a state where the upper end portion of the outer cylinder 22 is in contact with the inner peripheral surface of the reduced diameter portion 11.
Moreover, when the inner plug 3 is mounted, as shown in FIG. 2, the closing member 30 covers the upper end surface of the inner cylinder 21 and closes the upper portion of the storage chamber R, and the through-hole formed in the inner cylinder 21. One side of 26 is shielded. Therefore, the inner cylinder 21 is prevented from moving in the direction of the container axis O during this mounting. Therefore, it is possible to efficiently perform the mounting operation of the inner plug 3 without paying special attention to the second content W2.

  Subsequently, the overcap 4 is attached to the mouth 10 of the container body 2. Specifically, the overcap 4 is rotated around the container axis O, and the female screw portion 40 a of the peripheral wall cylinder 40 is screwed into the male screw portion 10 a of the mouth portion 10. Then, as shown in FIG. 3, the push-down portion 42 enters the inside of the inner cylinder 21 through the spout 31 and moves downward while contacting the inner peripheral surface of the inner cylinder 21 and the inner surface of the spout 31. At this time, the push-down portion 42 moves downward while being in contact with the inner peripheral surface of the inner cylinder 21 while blocking the other side of the through-hole 26 formed in the inner cylinder 21, and then the tip is moved to the protrusion 27. Contact. Accordingly, the push-down portion 42 can apply a downward force to the inner cylinder 21 via the protrusion 27 while shielding the other side of the through hole 26.

Then, by this downward force, the bottom wall portion 23 connecting the outer cylinder 22 and the inner cylinder 21 is reversely deformed with the lower end portion of the outer cylinder 22 as a base point, and the inner cylinder 21 is moved along the container axis O. Move down. Therefore, the through hole 26 formed in the inner cylinder 21 also moves downward, and one side of the through hole 26 that is shielded by the closing member 30 communicates with the inside of the accommodation chamber R through the annular groove 32.
At this time, since the other side of the through hole 26 is shielded by the push-down portion 42, there is no possibility that the second content W <b> 2 in the storage chamber R flows inside the inner cylinder 21 through the through hole 26. Accordingly, the first content W1 and the second content W2 are in a state of being accommodated independently at this time.
Thus, when the overcap 4 is attached, the production of the mixing container 1 is completed.

Next, the case where the mixing container 1 manufactured in this way is used is demonstrated.
First, as shown in FIG. 4, the overcap 4 is rotated around the container axis O in the direction opposite to the previous direction and removed from the mouth portion 10 of the container body 2. Then, since the push-down portion 42 that shields the other side of the through hole 26 of the inner cylinder 21 is detached from the mouth portion 10 together with the overcap 4, the other side of the through hole 26 is in communication with the inner side of the inner cylinder 21. . That is, the inside of the container body 2 and the inside of the storage chamber R are in communication with each other through the through hole 26. Therefore, when the first content W1 is poured out through the inner cylinder 21 and the spout 31 of the inner plug 3, the second content W2 can be mixed.
In this way, the first content W1 and the second content W2 can be poured out while being mixed.

  In particular, the mixing container 1 according to the present embodiment is different from the conventional container in which the first contents and the second contents are mixed by puncturing the top wall portion of the cap or the inner cylinder. The first content W1 and the second content W2 are mixed by the downward movement of the inner cylinder 21. Therefore, inconvenience such as drowning hardly occurs at the time of puncturing. Accordingly, the first content W1 and the second content W2 can be efficiently poured out while being mixed.

  Further, in the present embodiment, since a plurality of through holes 26 are formed at equal intervals around the container axis O, when the container body 2 is tilted and poured out, in which direction the container body 2 is inclined Also, the first content W1 and the second content W2 can be mixed without any unevenness. Therefore, the reliability as the mixing container 1 can be improved.

In addition, once the bottom wall portion 23 is reversely deformed, an upward force is unlikely to act on the bottom wall portion 23. Therefore, after the overcap 4 is removed, the bottom wall portion 23 is reversely deformed in the reverse direction and does not return to its original state. Therefore, the possibility that the inner cylinder 21 moves upward and one side of the through hole 26 is again shielded by the closing member 30 is low. Therefore, also in this point, it is difficult to prevent the dispensing.
Furthermore, when the inner plug 3 is attached to the inside of the mouth portion 10 of the container body 2, the accommodation chamber R that accommodates the second contents W2 is in a closed state, so that the operation of attaching the inner plug 3 can be performed efficiently. It is possible to improve the manufacturing efficiency.

  Further, since the protrusion 27 is used, the inner cylinder 21 is moved downward while shielding the other side of the through-hole 26 with a simple configuration in which the push-down portion 42 is not formed in a complicated shape but is formed in a cylindrical shape. In addition to being able to move, the other side of the through hole 26 can be communicated with the inside of the inner cylinder 21 simultaneously with the removal of the overcap 4. Therefore, the shape of the overcap 4 can be simplified, and the cost can be reduced.

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

  For example, in the embodiment described above, the overcap 4 is detachably mounted by screwing the female threaded portion 40a of the peripheral wall cylinder 40 into the male threaded portion 10a of the mouth portion 10, but this is not a limitation, and the fitting is not limited thereto. It may be configured to be detachably attached, for example.

Moreover, in the said embodiment, although it was set as the structure which applies downward force to the inner cylinder 21 via the projection part 27, and moves this inner cylinder 21 downward, it is not limited to this case. For example, the inner cylinder 21 may be moved downward by pushing down the upper end portion of the inner cylinder 21. In this case, the push-down portion 42 may be formed in a stepped shape so as to contact the upper end portion of the inner cylinder 21 and simultaneously shield the other end side of the through hole 26.
However, as in the above-described embodiment, it is more preferable that the protrusions 27 are formed on the inner peripheral surface of the inner cylinder 21 so that the push-down part 42 is simply formed in a cylindrical shape. In addition, even if the push-down portion 42 is formed in a columnar shape instead of a cylindrical shape, the same effect can be obtained.

  Further, the through hole 26 and / or the annular groove 32 may not be provided. In this case, a configuration may be adopted in which a gap is formed between the upper end portion of the inner cylinder 21 and the closing member 30 when the inner cylinder 21 is lowered.
