JP 2000-159249 A

However, in the above-described conventional refill container, after opening the spout of the inner stopper, it is necessary to screw the mouth of the main container into the inner stopper, and then turn the refill container and the main container upside down. Work was easy to become complicated.
Also, since the mouth of the container is screwed into the refill container after opening the spout of the inner plug, if the refill container is accidentally tilted during the screwing operation, the contents in the refill container will spill. There was a risk of getting out.
Further, since the container is placed in an inverted position when the mouth of the container is screwed onto the inner plug, the contents in the container are likely to spill if the contents remain inside the container. Therefore, it was difficult to perform refilling work after the contents in the container were used up.

  The present invention has been made in view of such circumstances. The purpose of the present invention is to enable easy refilling work and to prevent the contents from being spilled during refilling. An object of the present invention is to provide a refill container that can be refilled even if it remains.

In order to achieve the above object, the present invention provides the following means.
A refill container according to the present invention includes a container main body in which contents to be refilled in the main container are accommodated, a mounting cylinder that is attached to a mouth portion of the container main body and formed with a spout, and a seal that closes the spout. And an operating member locked to the mounting cylinder so as to be slidable toward the seal portion side along the container axial direction, and the slide of the operating member is disposed between the mounting cylinder and the operating member A restricting member that restricts movement, and the operating member includes a main body cylinder portion that is externally fitted to the attachment cylinder, a central cylinder portion that is disposed inside the attachment cylinder, the main body cylinder portion, and the A connecting plate having an opening, connecting a central cylinder part, a pressing body that presses the seal part in accordance with a sliding movement with respect to the mounting cylinder, and arranged outside the pressing body in a radial direction; At the opening edge of the inlet of the container It has a contact piece which is capable contact, the said regulating member, characterized in that it is integrally connected to the hollow mounting or the operating member through the first weakened portion breakable.

According to the refill container according to the present invention, when the contents are refilled in the container, first, the contact piece of the operation member is brought into contact with the opening edge of the injection port portion, and the refill container and the container are combined. . And the seal part which obstruct | occludes this spout by sliding the operation member toward the spout side by moving the container main body of this refilling container and this container relatively close along a container axial direction. Is pressed by a pressing body to be broken or detached from the spout, and the spout is opened.
As a result, the inside of the mounting cylinder communicates with the spout, so that the inside of the container body of the refill container and the inside of the inlet of the main container communicate with each other, and the contents in the container main body are poured out into the inlet part. Refilled inside.

  As described above, after the refill container and the main container are combined with the contact piece being in contact with the opening edge of the inlet, the main body and the main container are relatively close to each other along the container axial direction. Since the contents can be refilled by a simple operation of moving, the refilling operation can be facilitated.

Further, when refilling, the contact piece arranged on the outer side in the radial direction from the pressing body is brought into contact with the opening edge of the injection port, so that the refill container can be combined with this container in a stable state, and the mounting cylinder Can be inserted into the inlet. Therefore, it is difficult to spill the contents.
In addition, since the operation member can be stabilized by bringing the contact piece into contact with the opening edge of the inlet port as described above, the operation member can be moved smoothly and an excessive force is required. It is easy to open the spout easily by pressing the seal portion without stopping.
In addition, since the contents can be refilled in the container at the same time as the refill container is opened, it is possible to perform refilling work without placing the container in an inverted position, and the contents remain in the container. Even so, the contents can be refilled.

Here, since the regulating member that regulates the sliding movement of the operation member is arranged between the mounting cylinder and the operation member, even if an external force is unexpectedly applied to the refill container at the distribution stage or the like, It is possible to prevent the pressing body from pressing the seal portion by restricting the slide movement, and it is possible to prevent the refill container from being opened unexpectedly.
In particular, since the restriction member is integrally connected to the mounting cylinder or the operation member via the first weakening portion, the number of parts can be reduced as compared with the case where the restriction member is provided separately.
Furthermore, after the container body is inverted and combined with this container while the spout is sealed with the sealing portion, the operation member can only be slid by removing the restricting member. Spilling can be prevented.

  In the refill container of the present invention, the seal portion is integrally connected to the mounting cylinder via a fragile second weakening portion, and the pressing body includes the second weakening portion and the container shaft. The blade part may be formed in the position which opposes in a direction.

  In this case, in addition to the regulating member, the number of parts can be further reduced by integrally connecting the seal portion to the mounting cylinder via the second weakening portion.

According to the refill container according to the present invention, the refilling operation can be easily performed, and it is difficult to spill the contents at the time of refilling, and the refilling work can be performed even when the contents in the container remain. It can be carried out.
In particular, since the restricting member is integrally connected to the contact piece of the mounting cylinder or the operation member via the first weakening portion, the number of parts can be reduced as compared with the case where the restricting member is provided separately. it can.

Hereinafter, embodiments of a refill container according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, the refill container 1 of the present embodiment is mounted on a container body 2 in which the contents W to be refilled in the container 40 (see FIG. 2) are stored, and the mouth 2 a of the container body 2. In addition, the mounting cylinder 4 in which the spout 3 is formed, the seal portion 5 that closes the spout 3, the operation member 6 supported by the mounting cylinder 4 so as to be slidable along the container axis O direction, and the operation member And a restricting member 7 that is detachably connected to 6 and restricts the sliding movement of the operating member 6 toward the spout 3 side.

  In addition, the container main body 2, the mounting cylinder 4, the seal | sticker part 5, and the operation member 6 mentioned above are arrange | positioned in the state in which each center axis line was located on the common axis. In the present embodiment, this common axis is referred to as a container axis O, and in the refill container 1 described above, the operation member 6 side along the container axis O is referred to as an upper side, and the container body 2 side is referred to as a lower side. A direction perpendicular to the container axis O is referred to as a radial direction, and a direction around the container axis O is referred to as a circumferential direction.

The mounting cylinder 4 includes a seal cylinder part 10 fitted in the mouth part 2 a of the container body 2, an outer cylinder part 11 screwed to the outer surface of the mouth part 2 a of the container body 2, and an upper end of the seal cylinder part 10. The connecting ring 12 disposed on the opening edge of the mouth portion 2a, and the guide tube portion 14 extending upward from the inner peripheral edge of the connecting ring 12. I have.
The inner peripheral edge of the connecting ring 12 protrudes inward in the radial direction from the seal cylinder part 10, and the inner diameter of the guide cylinder part 14 is smaller than that of the seal cylinder part 10. Further, an annular groove 12 a that opens toward the outer side in the radial direction is formed on the outer peripheral edge of the connecting ring 12.

  And the lower end opening part of the guide cylinder part 14 is the spout 3 mentioned above. In addition, an annular engagement protrusion 14 a that protrudes radially outward is formed at the upper end of the guide tube portion 14.

  The seal portion 5 is a plug-like member that is liquid-tightly fitted to the spout 3 and is connected to the seal tube portion 5a that is fitted in the opening of the guide tube portion 14 and the lower end portion of the seal tube portion 5a. And a sealing body 5b that closes the sealing cylinder portion 5a. Further, the outer peripheral edge of the seal body 5 b protrudes outward in the radial direction from the seal cylinder portion 5 a and is in contact with the lower surface of the connecting ring 12.

The operation member 6 includes a main body cylinder portion 20 that is externally fitted to the guide cylinder portion 14 of the mounting cylinder 4 so as to be slidable, and a flange-shaped contact that protrudes radially outward from a lower end portion of the main body cylinder portion 20. A piece 21, a central cylindrical part (pressing body) 22 disposed in the main body cylindrical part 20, an annular connecting plate 23 that connects the upper part of the central cylindrical part 22 and the upper part of the main body cylindrical part 20, It has. The main body cylinder portion 20 and the central cylinder portion 22 are disposed coaxially with the container axis O.
The lower end of the main body cylinder portion 20 is undercut fitted to the engagement protrusion 14a of the guide cylinder portion 14 described above.

  The abutting piece 21 is extended over the entire outer peripheral surface of the main body cylinder portion 20, and the outer peripheral edge thereof is located on the radially inner side of the outer peripheral surface of the outer cylinder portion 11. The contact piece 21 is formed with a plurality of ribs 25 protruding upward in the circumferential direction at intervals. These ribs 25 extend along the radial direction, and the upper surface of each rib 25 abuts on the opening edge of the inlet 41 (see FIG. 2) of the container 40.

The center cylinder portion 22 has the same upper end edge as the upper end edge of the main body cylinder portion 20 and the position in the container axis O direction, and the lower end portion faces the seal body 5b of the seal portion 5 (preferably, close or abuts). )doing. Moreover, the upper end part of the center cylinder part 22 is gradually diameter-expanded toward the upper part from the downward direction.
The connecting plate 23 is disposed above the contact piece 21, and a plurality of openings 23 a are formed in the connecting plate 23 at intervals in the circumferential direction.

Here, the restricting member 7 is formed in a cylindrical shape arranged coaxially with the container axis O, and surrounds the guide cylinder portion 14 over the entire circumference from the outside in the radial direction.
In this case, the restricting member 7 is configured to restrict the downward movement of the contact piece 21 between the annular groove 12 a of the mounting cylinder 4 and the contact piece 21. Specifically, the upper end portion of the regulating member 7 is integrally connected to the outer peripheral edge of the contact piece 21 via a weakened portion (first weakened portion) 31 that can be broken. However, the weakened portion 31 may be configured to be connected to the lower surface of the contact piece 21. The weakening portion 31 is formed thinner than the regulating member 7 and the contact piece 21, and is formed at the upper end portion of the regulating member 7 over the entire circumference. On the other hand, the lower end portion of the restricting member 7 is disposed in the annular groove 12a of the connecting ring 12, and is externally fitted to a peripheral wall located inside in the radial direction in the annular groove 12a.

The restricting member 7 is integrally formed with the restricting member 7 with a knob piece 32 protruding outward in the radial direction.
In the vicinity of the portion where the knob piece 32 is formed, the regulating member 7 is preferably divided in the circumferential direction by a slit (not shown) extending in the container axis O direction or connected so as to be capable of being divided.

Next, a method for refilling the contents W from the refill container 1 configured as described above into the main container 40 will be described.
First, the refill container 1 is placed above the main container 40 while the refill container 1 is in an inverted posture and the main container 40 is in an upright posture. Then, the refill container 1 and the main container 40 are moved relative to each other in the direction of the container axis O while aligning them, and the contact piece 21 of the operation member 6 is brought into contact with the opening edge of the inlet portion 41 of the main container 40. The refill container 1 and the main container 40 are combined with each other. At this time, the refill container 1 and the main container 40 are combined with the main body cylinder portion 20 of the operation member 6 being inserted into the inlet 41 of the main container 40.

Here, in the present embodiment, as described above, the refill container 1 is turned upside down, so that the top and bottom of the refill container 1 are inverted, and the operation member along the container axis O direction in the refill container 1 in the inverted position. The 6 side is the lower side, and the container body 2 side is the upper side.
Further, since the spout 3 of the refill container 1 is closed by the seal portion 5 (see FIG. 1), the contents W in the container body 2 are exposed to the outside through the spout 3 even when the refill container 1 is turned upside down. There is no spillage. Furthermore, since the regulating member 7 is disposed between the mounting cylinder 4 and the operating member 6, the sliding movement of the operating member 6 is regulated. Further, since the outer peripheral edge of the seal body 5b is in contact with the lower surface of the connecting ring 12, the seal portion 5 is prevented from being opened by the weight of the contents W.

  In this state, the regulating member 7 is separated from the refill container 1. Specifically, when the knob piece 32 of the regulating member 7 is picked and pulled outward in the radial direction, the weakening portion 31 that connects the regulating member 7 and the contact piece 21 starts from the base end portion of the knob piece 32. The restriction member 7 is separated from the contact piece 21 along the circumferential direction. Thereby, the regulating member 7 is separated from the refill container 1, and the downward movement of the mounting cylinder 4 is released. In addition, after separating the regulating member 7 from the refill container 1, the refill container 1 may be placed in an upright posture, and the refill container 1 may be disposed above the main container 40 with the main container 40 in an upright posture. Good.

  Then, as shown in FIG. 2, when the container body 2 of the refill container 1 and the main container 40 are relatively moved along the container axis O direction, the opening edge of the inlet 41 of the main container 40 is Since the abutting piece 21 is pushed toward the spout 3 side, the operating member 6 can be slid toward the spout 3 side. Then, the central cylinder portion 22 of the operation member 6 presses the seal body 5b of the seal portion 5 to disengage from the spout 3 and opens the spout 3 and enters the seal tube 10 of the mounting cylinder 4. To do. At this time, the guide cylinder portion 14 in the mounting cylinder 4 and the main body cylinder portion 20 in the operation member 6 are inserted into the injection port portion 41 of the main container 40 and disposed in the injection port portion 41.

  Thereby, the inside of the container main body 2 of the refill container 1 and the inside of the inlet part 41 of the main container 40 communicate with each other through the spout 3, the central cylinder part 22 and the opening part 23 a of the connecting plate 23. Therefore, the contents W accommodated in the container main body 2 of the refill container 1 can be poured out into the inlet 41 of the main container 40 through the opening 23a (arrow A shown in FIG. 2). The item W can be refilled from the refill container 1 to the main container 40.

Moreover, it can also be set as the structure which performs air substitution from the inside of this container 40 to the inside of the container main body 2 of the refill container 1 through the inside of the center cylinder part 22 during the refilling work (arrow B shown in FIG. 2). ), The contents W can be smoothly poured into the container 40 and the refilling operation can be performed efficiently.
In this embodiment, the contact piece 21 of the refill container 1 and the opening edge of the inlet 41 of the container 40 are in contact with each other via the rib 25 formed on the contact piece 21. A gap is provided between the contact piece 21 and the opening edge of the injection port 41. Therefore, the inside and the outside of the container 40 can be communicated with each other through the gap between the inlet 41 and the guide cylinder 14 and between the opening edge of the inlet 41 and the contact piece 21. Therefore, the inside of this container 40 can be communicated with the outside through this gap, and for example, the air inside this container 40 can be discharged to the outside (arrow B shown in FIG. 2).

As described above, according to the refill container 1 of the present embodiment, after the refill container 1 and the main container 40 are combined in a state where the contact piece 21 is in contact with the opening edge of the inlet 41, the container body Since the contents W can be refilled by a simple operation of relatively moving the container 2 and the main container 40 along the container axis O direction, the refilling operation can be facilitated.
Further, when refilling, the contact piece 21 is brought into contact with the opening edge of the injection port 41, so that the refill container 1 in the inverted posture can be combined with the main container 40 in a stable state, and the mounting cylinder 4 Since the guide tube portion 14 can be inserted into the injection port portion 41, the refill container 1 and the main container 40 can be combined without being displaced in the radial direction. Therefore, it can suppress that the content W spills.

Moreover, since the operation member 6 can be stabilized by bringing the contact piece 21 into contact with the opening edge of the inlet 41 as described above, the operation member 6 can be smoothly moved along the container axis O direction. Can slide. Therefore, the spout 3 can be easily opened by pressing the seal portion 5 without requiring an excessive force. In this respect, the refilling operation is easy to perform.
Furthermore, since the contents W can be refilled in the main container 40 at the same time as the refill container 1 is opened, the refilling operation can be performed without placing the main container 40 in an inverted posture. Even if the article W remains, the refilling work of the contents W can be performed.

Moreover, since the regulating member 7 that regulates the downward movement of the operation member 6 is disposed between the mounting cylinder 4 and the operation member 6, even if an external force is unexpectedly applied to the refill container 1 at the distribution stage or the like. The sliding movement of the operation member 6 can be restricted to prevent the central tube portion 22 from pressing the seal portion 5, and the refill container 1 can be prevented from being opened unexpectedly.
In particular, since the regulating member 7 is integrally connected to the contact piece 21 of the operation member 6 via the weakened portion 31, it is possible to reduce the number of parts compared to the case where the regulating member 7 is provided separately. it can.
Furthermore, the restriction member 7 can be removed in a state where the refill container 1 and the main container 40 are combined at the time of refilling. In this case, since the operation member 6 is slidable only after removing the regulating member 7 after the container body 2 is combined with the main container 40 while the spout 3 is sealed with the seal portion 5, the contents are changed during the refilling operation. It is possible to reliably prevent the object W from spilling.

  Note that it is preferable that the sliding movement of the operation member 6 is suppressed even after the restricting member 7 is removed. Specifically, the guide tube portion 14 is press-fitted into the main body tube portion 20 to such an extent that the operation member 6 can slide, or the lower end portion of the main body tube portion 20 of the operation member 6 is engaged from below. For example, it is possible to form a locking projection that can be overcome by sliding movement of the operation member 6 on the outer surface of the guide tube portion 14.

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

For example, in the above-described embodiment, the configuration in which the restriction member 7 is integrally connected to the contact piece 21 of the operation member 6 via the weakening portion 31 is described. You may connect. Specifically, as shown in FIG. 3, the upper end portion of the regulating member 7 contacts the lower surface of the contact piece 21, while the lower end portion is integrated with the upper surface of the connection ring 12 of the mounting cylinder 4 via the weakening portion 31. You may make it the structure connected with.
Even if comprised in this way, there can exist an effect similar to embodiment mentioned above. Further, by configuring the restricting member 7 so as to be sandwiched in the container axis O direction by the lower surface of the contact piece 21 and the upper surface of the connecting ring 12, the downward movement of the operation member 6 can be more reliably restricted.

In the above-described embodiment, the case where the center cylinder portion 22 is used to press the seal body 5b of the seal portion 5 as the pressing body that presses the seal portion 5 has been described. However, the center cylinder portion 22 is not provided. It doesn't matter. That is, the inner cylinder part 24 arrange | positioned inside the radial direction of the main body cylinder part 20 is formed, and the upper end opening edge of the seal cylinder part 5a of the seal part 5 is pressed using this inner cylinder part 24 as a pressing body. It doesn't matter. Specifically, the inner cylinder portion 24 is undercut fitted to an engagement protrusion 14 a that protrudes inward in the radial direction from the upper end portion of the guide cylinder portion 14, and the lower end opening edge is a seal in the seal portion 5. It faces the upper end surface of the cylindrical portion 5a.
In this case, when the refill container 1 and the main container 40 are combined at the time of refilling, when the two are relatively moved along the container axis O direction, as shown in FIG. The lower end surface (upper side in FIG. 4) presses the upper end surface (lower side in FIG. 4) of the seal cylinder portion 5a of the seal portion 5. As a result, the seal portion 5 is detached from the spout 3 and the spout 3 is opened. As a result, the contents W in the container body 2 of the refill container 1 can be poured into the main container 40 through the spout 3 and the inner cylinder portion 24 (arrow A shown in FIG. 4).

In the above-described embodiment, the configuration in which the seal portion 5 is provided separately from the mounting cylinder 4 is described. However, the configuration is not limited thereto, and the sealing section 5 may be integrally connected to the mounting cylinder 4. Specifically, as shown in FIG. 5, the lower end portion of the spout 3 is provided with a weakened portion (second weakened portion) 51 that can break the disc-shaped seal portion 5 that closes the spout 3. It is integrally connected to the mounting cylinder 4. The weakened portion 51 is formed thinner than the seal portion 5 and is connected to the lower portion of the outer peripheral edge of the seal portion 5 over the entire circumference.
Further, in this case, the thickness of the pressing body that presses the seal portion 5 (weakening portion 51) is reduced so that the inner diameter gradually increases toward the lower end of the inner cylinder portion 24 of the main body cylinder portion 20 as it goes downward. It is preferable to form the blade portion 53. Furthermore, the lower end opening edge of the inner cylinder part 24 shown in FIG. 5 is formed to bend obliquely so as to protrude gradually downward from one end side to the other end side along the circumferential direction.

According to this configuration, in addition to the regulating member 7, the seal portion 5 is integrally connected to the mounting cylinder 4, whereby the number of parts can be further reduced.
Further, at the time of refilling, when the container body 2 of the refillable container 1 and the main container 40 are combined and moved relatively along the container axis O direction, as shown in FIG. The blade portion 53 of the cylindrical portion 52 presses the weakened portion 51 and breaks the weakened portion 51. As a result, the seal portion 5 is detached from the spout 3 and the spout 3 is opened. As a result, the contents W in the container main body 2 of the refill container 1 can be poured into the main container 40 through the spout 3 and the inner cylinder portion 24 (arrow A shown in FIG. 6). In this case, by forming the lower end portion of the inner cylindrical portion 24 obliquely, the pressing force acting on the weakened portion 51 from the inner cylindrical portion 24 can be easily concentrated, so that the weakened portion 51 can be easily broken. In this respect, the refilling operation is easy to perform.

  Moreover, in the structure mentioned above, although the case where the press body was formed in the cylinder shape was demonstrated, it is not restricted to this. In other words, the pressing body may be configured in any way as long as the seal portion 5 can be pressed as the operating member 6 slides. For example, the pressing body may be a rod-like or plate-like member extending in the container axis O direction. In this case, the number of pressing bodies may be one, or a plurality of pressing bodies may be arranged at intervals around the container axis O in the circumferential direction.

In the configuration shown in FIG. 7, the pressing body includes a semi-cylindrical pressing piece 52 that extends in the radial direction of the main body cylinder portion 20 and extends in the container axis O direction. At the lower end portion of the pressing piece 52, a blade portion 53 is formed which becomes thinner as it goes downward. In addition, a rib 55 that protrudes inward in the radial direction is formed at the central portion in the circumferential direction of the pressing piece 52 over the entire region of the pressing piece 52 in the container axis O direction.
In this case, when the container body 2 of the refill container 1 and the main container 40 are moved relatively close to each other along the container axis O direction at the time of refilling, as shown in FIG. The weakening part 51 is pressed and the weakening part 51 is fractured. As a result, the seal portion 5 is detached from the spout 3 and the spout 3 is opened. As a result, the contents W of the container main body 2 of the refill container 1 can be poured into the main container 40 through the outlet 3 and the main body cylinder portion 20 (arrow A shown in FIG. 8).

  Moreover, although embodiment mentioned above demonstrated the case where the contact piece 21 was formed over the perimeter of the main body cylinder part 20, you may divide into not only this but in multiple.

  In the above-described embodiment, the case where the weakened portion 31 is formed thinner than other portions has been described. However, the present invention is not limited to this, and the design can be changed as appropriate, such as forming a perforation.
