However, the conventional pouring container has a problem in that it is difficult to separate the container body and the cap body when disposing of the container.

The present invention has been made in view of the above-mentioned circumstances, and is a dispensing device that allows easy separation of the container main body and the cap main body when disposing of the pipe even if the mounting tube is attached to the mouth part by plugging. The purpose is to provide a container.

The present invention employs the following means to solve the above problems. That is, the dispensing container of the present invention includes a container main body in which the contents are stored, a mounting tube mounted on the mouth of the container main body, and a cap main body having a communication hole communicating with the inside of the container main body. A multi-thread thread is formed on one of the outer circumferential surface of the mouth portion and the inner circumferential surface of the mounting tube, and a vertical rib extending in the vertical direction is formed on either one of the outer circumferential surface of the mouth and the inner circumferential surface of the mounting tube. A first engaging portion that engages with the multi-thread screw is formed with the outer shape of the multi-thread screw being transferred , and a first engaging portion that engages with the multi-thread screw is formed on the outer circumferential surface of the mouth portion and the inner circumferential surface of the mounting tube. A horizontal rib extending in the circumferential direction is formed on one of the sides, and a second engaging portion that engages with the horizontal rib is formed with the outer shape of the horizontal rib being transferred to the vertical rib. The rib extends from the thread of the multi-thread screw toward the slack side along the circumferential direction .

According to the present invention, since the first engaging portion that engages with the multi-thread screw is formed on the vertical rib with the external shape of the multi-thread screw transferred, the mouth portion and the mounting cylinder can be moved in the circumferential direction. When the first engaging portion is relatively rotated toward the loosened side along the multithread thread, the mounting tube can be easily removed from the mouth portion. As a result, even if the mounting tube is attached to the mouth by a stopper, the container body and the cap body can be easily separated when discarded.
Since the first engaging portion is formed by transferring the external shape of the multi-thread screw to the vertical rib, the threads that make up the multi-start thread intersect with each other, and a portion of each thread is formed on the vertical rib. For example, compared to the case where each thread constituting a multi-thread thread is transferred over the entire length in the circumferential direction to either the outer circumferential surface of the mouth part or the inner circumferential surface of the mounting tube, , it becomes possible to increase the surface pressure generated between the vertical rib and the multi-thread screw, and the outer shape of the multi-thread screw can be transferred favorably to the vertical rib.
Since a multi-thread thread is formed on either the outer circumferential surface of the mouth or the inner circumferential surface of the mounting tube, instead of a single thread thread, the mounting tube can be easily attached without getting caught in the mouth by plugging. be able to.
By fitting the opening into the mounting cylinder, the external shape of the multi-thread screw can be transferred to the vertical rib, so there is no need to form the first engaging part on the vertical rib in advance, and the fitting of the mounting cylinder and the opening There is no need to adjust relative circumferential positions. Further, the cap body can be attached to the mouth portion simply by fitting the mouth portion into the mounting cylinder using a plug or the like. Therefore, it is possible to improve manufacturing efficiency and reduce manufacturing costs.

In this case, horizontal ribs extending in the circumferential direction are formed on either the outer circumferential surface of the mouth or the inner circumferential surface of the mounting tube, and the outer shape of the horizontal ribs is transferred to the vertical ribs. A second engaging portion that engages with the rib is formed. Therefore, when the cap body is pulled upward relative to the mouth portion, the second engaging portion engages with the horizontal rib, thereby suppressing the cap body from being disengaged upward from the mouth portion. .
As a result, even if there is no tamper evidence part that is connected to the lower opening edge of the mounting tube via the breakable weakened part and is exteriorized in a state that restricts upward movement at the mouth part, the cap When the main body is pulled upward relative to the mouth, it is possible to prevent the cap main body from separating upward from the mouth.

A tamper evidence part may be connected to a lower opening edge of the mounting tube via a breakable weakened part, and the tamper evidence part may be externally packaged in the mouth part in a state where upward movement is restricted.

In this case, the tamper evidence part is connected to the opening edge of the lower end of the mounting tube via the breakable weakened part, and the tamper evidence part is externally covered with the mouth part in a state where upward movement is restricted. When the mouth part and the mounting tube are rotated relative to each other in the circumferential direction toward the loose side, the weakened part is broken, the mounting tube and the tamper evidence part are separated, the mounting cylinder is separated upward from the mouth part, and the tamper evidence part remains in the mouth. Thereby, even if the mounting tube is attached to the mouth again, at least the weakened portion will have been broken, so it can be easily visually confirmed whether the mounting tube has ever been removed from the mouth.

Either the mouth portion or the mounting tube may be formed of a softer material than either one.

In this case, either the mouth or the mounting tube is made of a softer material than the other, so when the mouth is fitted into the mounting tube, deformation of the multi-thread screw is suppressed. At the same time, the outer shape of the multi-thread screw can be transferred well to the vertical ribs.

Threads constituting the multi-thread thread and adjacent to each other in the circumferential direction may be separated in the circumferential direction.

In this case, since the threads constituting the multi-thread thread and adjacent to each other in the circumferential direction are separated from each other in the circumferential direction, the mounting tube can be easily mounted without being caught in the mouth by plugging.

According to this invention, even if the mounting tube is attached to the mouth portion by plugging, the container main body and the cap main body can be easily separated at the time of disposal.

The cover plate 25 closes the lower end opening of the seal cylinder portion 24 . A communication hole 14 is formed in the covering plate 25 . A pouring tube 25d is formed on the upper surface of the covering plate 25, surrounding the communicating hole 14 from the outside in the radial direction and extending upward. A closing plate 25b is connected to the inner circumferential surface of the communication hole 14 via a breakable thin wall portion 25a. A pull ring 25c that projects upward is formed on the closure plate 25b.
Note that the cap body 15 may be configured, for example, without the top wall portion 22 and in which the inside of the mounting tube 13 is the communication hole 14.

A tamper evidence portion 21 is connected to the lower opening edge of the mounting tube 13 via a breakable weakened portion 19 .
The tamper evidence portion 21 is formed into a cylindrical shape and is externally wrapped around the mouth portion 12 . At the lower end of the tamper evidence portion 21, a plurality of retaining protrusions 21a are formed at intervals in the circumferential direction and protrude upward as they go inward in the radial direction. The upper end portion of the retaining protrusion 21a is in contact with a locking protrusion 12a formed on the outer peripheral surface of the mouth portion 12 from below the locking protrusion 12a. Thereby, the tamper evidence part 21 is externally packaged in the mouth part 12 in a state where upward movement is restricted. The locking protrusion 12a extends continuously over the entire length in the circumferential direction.

In this embodiment, a multi-start thread 16 is formed on either the outer peripheral surface of the mouth portion 12 or the inner peripheral surface of the mounting tube 13, and a vertical rib 17 extending in the vertical direction is formed on the other. is formed, and a first engaging portion 18 that engages with the multi-thread screw 16 is formed in a state where the external shape of the multi-thread screw 16 is transferred to the vertical rib 17 .

In the illustrated example, a multi-start thread 16 is formed on the outer circumferential surface of the mouth portion 12 , and a vertical rib 17 is formed on the inner circumferential surface of the mounting tube 13 . Note that the multiple thread screw 16 may be formed on the inner circumferential surface of the mounting cylinder 13 and the vertical ribs 17 may be formed on the outer circumferential surface of the mouth portion 12. The vertical ribs 17 extend straight in the vertical direction. Note that the vertical ribs 17 may extend in the vertical direction while being inclined or curved. The multiple thread screw 16 and the vertical rib 17 are located above the locking protrusion 12a of the mouth portion 12. The threads 16a of the multi-thread screw 16 and the widths of the vertical ribs 17 are equal to each other. Note that a plurality of threads 16a may be provided at intervals in the vertical direction.

Either the mouth portion 12 or the mounting tube 13 is made of a softer material than the other.
In the illustrated example, the mounting tube 13 is made of a material softer than the mouth portion 12 . For example, the mounting tube 13 is made of polypropylene or polyethylene, and the opening 12 is made of polyethylene terephthalate or the like.

The first engaging portion 18 of the plurality of vertical ribs 17 engages with one of the plurality of threads 16a constituting the multi-thread screw 16. Threads 16a constituting the multi-thread screw 16 and adjacent to each other in the circumferential direction are spaced apart in the circumferential direction. The interval between the threads 16a adjacent to each other in the circumferential direction is wider than the width (circumferential size) of the vertical rib 17. The amount of radially inward protrusion at the lower end of the vertical rib 17 decreases as it goes downward. Thereby, when the mounting tube 13 is attached to the mouth portion 12 by plugging, the lower end portion of the vertical rib 17 can easily climb over the thread 16a downward. Note that the lower end portions of the vertical ribs 17 may extend linearly or curvedly in a longitudinal cross-sectional view along the common axis O.

As explained above, according to the dispensing container 1 according to the present embodiment, the first engaging portion 18 engages with the multi-thread screw 16 in a state where the external shape of the multi-thread screw 16 is transferred to the vertical rib 17. is formed, so when the opening portion 12 and the mounting tube 13 are relatively rotated in the circumferential direction toward the loose side, the first engaging portion 18 moves relatively along the multi-thread screw 16, and the mounting tube 13 can be easily removed from the mouth portion 12. Thereby, even if the mounting tube 13 is attached to the mouth portion 12 by plugging, the container body 11 and the cap body 15 can be easily separated when discarded.

Since the first engaging portion 18 is formed by transferring the outer shape of the multi-thread screw 16 to the vertical rib 17, the threads 16a constituting the multi-thread screw 16 intersect with each other on the vertical rib 17. A portion of the threads 16a will be transferred, and for example, each thread 16a constituting the multi-thread thread 16 may be transferred to the other of the outer circumferential surface of the mouth portion 12 and the inner circumferential surface of the mounting tube 13. Compared to the case of transferring over the entire length in the circumferential direction, it is possible to increase the surface pressure generated between the vertical rib 17 and the multi-thread screw 16, and the outer shape of the multi-thread screw 16 can be transferred well to the vertical rib 17. be able to.

Since a multi-thread thread 16 is formed on either the outer circumferential surface of the mouth portion 12 or the inner circumferential surface of the mounting tube 13, instead of a single thread thread, the mounting tube 13 can be caught in the mouth portion 12 by plugging. It can be easily installed.
By fitting the mouth portion 12 into the mounting cylinder 13, the outer shape of the multi-thread screw 16 can be transferred to the vertical rib 17, so there is no need to form the first engaging portion 18 on the vertical rib 17 in advance. There is no need to adjust the relative circumferential positions of the mounting tube 13 and the mouth portion 12. Further, the cap body 15 can be attached to the opening 12 simply by fitting the opening 12 into the mounting tube 13 using a plug or the like. Therefore, it is possible to improve manufacturing efficiency and reduce manufacturing costs.

A tamper evidence part 21 is connected to the lower opening edge of the mounting tube 13 via a breakable weakened part 19, and the tamper evidence part 21 is externally packaged in the mouth part 12 in a state where upward movement is restricted. Therefore, when the opening portion 12 and the mounting tube 13 are rotated relative to each other in the circumferential direction toward the loose side, the weakened portion 19 is broken, the mounting tube 13 and the tamper evidence portion 21 are separated, and the mounting tube 13 is attached to the opening portion 12. The tamper evidence portion 21 is removed upward from the mouth portion 12, and the tamper evidence portion 21 remains in the mouth portion 12. As a result, even if the mounting tube 13 is attached to the mouth portion 12 again, at least the weakened portion 19 will be broken, so it can be easily confirmed whether the attachment tube 13 has ever been detached from the mouth portion 12. Can be done.

Either the opening 12 or the mounting tube 13 is made of a softer material than the other, so when the opening 12 is fitted into the mounting tube 13, the multi-thread screw 16 is deformed. The outer shape of the multi-thread screw 16 can be well transferred to the vertical rib 17 while suppressing the problem.

Since the threads 16a constituting the multi-thread screw 16 and adjacent to each other in the circumferential direction are spaced apart in the circumferential direction, the mounting cylinder 13 can be easily mounted with less catching on the mouth portion 12 by plugging.

A second engaging portion 32 that engages with the horizontal rib 31 in the transferred state is formed.
In the illustrated example, the horizontal ribs 31 are formed on the outer peripheral surface of the mouth portion 12 . Note that the horizontal ribs 31 may be formed on the inner circumferential surface of the mounting tube 13. The horizontal rib 31 is connected to the thread 16a of the multi-thread screw 16. The horizontal rib 31 protrudes from the upper end of the thread 16a toward the slack side along the circumferential direction. The horizontal ribs 31 vertically face the lower end portions of the threads 16a that are located on the loose side along the circumferential direction among the threads 16a that are adjacent to each other in the circumferential direction. Both the first engaging portion 18 and the second engaging portion 32 are formed in a portion of the plurality of vertical ribs 17 .
