Description

  The present invention relates to a refill container.

Conventionally, for example, as described in Patent Document 1 below, a container main body in which contents to be refilled in this container are stored, and an inner plug that is attached to the mouth of the container main body and closes the mouth, There is known a refill container that performs refilling in a state where an inner plug is screwed into the mouth of the container. The inside plug is formed with a spout for pouring out the contents, and is provided with a seal portion for closing the spout. The seal portion is made of, for example, a lid provided with a pull top.
In this refill container, the pull top is first pulled up to open the spout of the inner plug. Next, the refill container is placed in an upright position (the mouth is in an upward position), and the mouth of the container in the inverted position (the mouth is in a downward position) is screwed onto the inner plug of the refill container. . From this state, the refill container and the main container are turned upside down to bring the main container into an upright posture and the refill container into an inverted posture. As a result, the contents in the refill container are refilled in the main container through the insides of the mouths of the refill container and the main container.

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. The work was complicated.
In addition, after opening the spout of the inner plug, the mouth of the container is screwed to the inner plug, so if the refill container is accidentally tilted during the screwing operation, the contents in the refill container are There was a risk of spilling out.
Furthermore, when the mouth of the container is screwed onto the inner plug, the container is turned upside down, so that the contents may spill if the contents remain in the container. Therefore, it was difficult to perform the refilling work unless the contents in the container were used up.

  The present invention has been made in view of such circumstances, and can be easily refilled, the contents are difficult to spill during refilling, and the contents in the container remain. It aims at providing the refill container which can perform refilling work even if it exists.

In order to solve the above problems, the present invention proposes the following means.
The refill container of the present invention includes a container main body in which contents to be refilled in the container are accommodated, a mounting cylinder that is attached to a mouth portion of the container main body and has a spout, and a seal portion that closes the spout. An operation member that is slidably moved toward the seal portion side at a portion located outside the container main body along the container axial direction from the seal portion in the attachment tube, Is formed with a groove that extends in the radial direction perpendicular to the container axial direction and extends in the container axial direction, and the operation member is disposed on the radially outer side of the mounting cylinder and is in contact with the container. A push-in portion that is disposed on the radially inner side of the mounting cylinder, pushes the seal portion in the container axial direction along with the sliding movement of the operating member relative to the mounting cylinder, and opens the spout. And the push-in part A connecting portion that is movable in the groove axis direction along the container axis direction, and a lid member that covers the operation member from the outside of the container body along the container axis direction is detachable on the mounting cylinder It is arranged in that.

When refilling the contents from the refill container according to the present invention into the container, first, the lid member is removed from the mounting cylinder to expose the operation member, and the contact portion of the operation member is connected to, for example, the mouth ( The refill container and the main container are combined in contact with the opening edge of the inlet). From this state, by moving the container body of the refill container and the main container relatively close along the container axial direction, the operating member is slid toward the spout side with respect to the mounting cylinder, and the pouring is performed. The seal portion closing the outlet is pushed in by the push-in portion, and is broken or separated from the spout to open the spout.
As a result, the inside of the container main body communicates with the spout, so that the inside of the container main body and the inside of the inlet of the main container communicate with each other, and the contents in the container main body enter the main container through the outlet and the inlet. Refilled.

  Thus, after combining the refill container and the main container with the contact portion of the refill container in contact with the opening edge of the inlet of the main container, the container body and the main container are moved in the container axial direction. Since the contents can be refilled by a simple operation of relatively moving along, the refilling operation can be facilitated.

Further, when refilling, the abutting portion disposed radially outward from the pushing portion is brought into contact with the opening edge of the inlet of the main container, so that the refill container can be combined with the main container in a stable posture. At the same time, the mounting cylinder can be inserted into the injection port. Therefore, it is difficult to spill the contents.
Further, as described above, since the operation member can be stabilized by bringing the contact portion into contact with the opening edge of the inlet portion, the operation member can be moved smoothly, and an excessive force can be applied. It is easy to open the spout by pushing the seal part without need.
Furthermore, since the contents can be refilled into the main container at the same time as the refill container is opened, the refilling operation can be performed without placing the main container in an inverted position. Therefore, even if the contents remain in the container, the contents can be refilled.

In addition, the contact portion and the push-in portion of the operation member are connected by a connecting portion that can move in the groove portion of the mounting cylinder, and can be moved integrally by the connecting portion. However, the outer shape along the container axial direction of the operation member is compact.
Further, since the connecting portion is inserted into the groove portion, the posture of the operation member when the operating member slides relative to the mounting cylinder is stabilized.

In addition, since the mounting cylinder is provided with a lid member that covers the operation member, even if an external force is unexpectedly applied to the refill container at the distribution stage or the like, the lid member regulates the sliding movement of the operation member. Thus, the push-in part can be prevented from pushing in the seal part, and the refill container can be prevented from being opened unexpectedly.
Further, by disposing the lid member on the mounting cylinder, it is possible to prevent foreign matter from entering the mounting cylinder.

  Moreover, the refill container of this invention WHEREIN: The said cover member is good also as being connected with the said operation member via the hinge part.

In this case, since the lid member and the operation member are connected to each other, the sliding movement of the operation member with respect to the mounting cylinder is reliably restricted in a state where the lid member is mounted on the mounting cylinder.
Further, the lid member, the hinge portion, and the operation member can be integrally formed. In this case, the number of parts can be reduced, the structure is simplified, and the assembly at the time of manufacture is easy.

  Moreover, the refill container of this invention WHEREIN: The said connection part is good also as abutting on the inner surface which faces the said connection part side in the said groove part at the terminal of the sliding movement of the said operation member with respect to the said mounting cylinder.

  In this case, as the operating member slides, the connecting portion of the operating member comes into contact with the inner surface of the groove portion of the mounting cylinder. Leaking to the outside in the radial direction is suppressed.

  Further, in the refill container of the present invention, the push-in portion has a cylindrical shape, and a protruding portion is provided on an end surface of the push-in portion that faces the seal portion so that a part of the end surface around the container axis protrudes. It is good also as being formed.

  In this case, when the push-in portion pushes in the seal portion, it can be brought into contact with the seal portion from the projection portion, whereby the seal portion is broken or detached from the spout so as to be inclined with respect to the container shaft. It is easy to open the spout.

  In the refill container of the present invention, at least one of a rib and a groove extending in the container axial direction may be formed on the inner surface of the protrusion that faces the radially inner side.

  In this case, when the push-in part pushes in the seal part and the spout is opened (opened), the ribs and grooves of the protrusions are abutted against the liquid level of the contents to balance the surface tension acting on the liquid level. By breaking and making it unbalanced, it becomes possible to trigger replacement of the contents in the container body and the air in the container. Therefore, even if the viscosity of the contents is high, the contents of the container body can be reliably refilled into the container without clogging the outlet.

  Further, in the refill container according to the present invention, the lid member is disposed in an opening portion on the opposite side to the spout along the container axial direction in the mounting cylinder, and the lid member is fitted in the opening portion. The fitting cylinder part to be provided is provided, and the inner peripheral surface of the opening part may be gradually inclined outward in the radial direction along the container axial direction toward the side opposite to the spout.

  In this case, it is easy to fit the fitting cylinder portion of the lid member to the opening portion of the mounting cylinder. Therefore, it is easy to attach and remove the lid member from the mounting cylinder.

  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 operation is performed even when the contents in the container remain. Can do.

On the inner peripheral surface of the peripheral wall 8b, a female screw portion 8c that is screwed into the male screw portion 2b of the mouth portion 2a is formed. The lower end opening edge of the peripheral wall 8b is disposed close to the flange 2c of the mouth portion 2a from above.

  The extraction tube 10 rises from the inner peripheral edge of the top wall 8a of the base tube 8. In the illustrated example, the inner diameter of the dispensing cylinder 10 is smaller than the inner diameter of the seal cylinder 9. The spout 3 is located at the radially inner portion (inside) at the lower end of the pour tube 10. In the dispensing cylinder 10, the upper end portion located on the opposite side of the container axis O direction from the dispensing outlet 3 is an opening 10 a communicating with the dispensing outlet 3. The inner peripheral surface of the opening 10a is gradually inclined outward in the radial direction along the container axis O direction toward the side opposite to the spout 3 (that is, the upper side). A groove 11 that penetrates in the radial direction and extends in the container axis O direction is formed in a portion other than the lower end portion of the dispensing cylinder 10.

  The groove portion 11 is formed such that a portion along the circumferential direction of the dispensing tube 10 is cut out. In the present embodiment, one groove portion 11 having a narrow slit shape is formed in the circumferential direction. The upper end portion of the groove portion 11 is opened at the upper end opening edge of the dispensing tube 10. An inner surface (bottom surface) 11 a facing upward is formed at the lower end of the groove 11. In the present embodiment, the shape of the inner surface 11a is a substantially rectangular plane corresponding to the shape of the connecting portion 14 described later of the operation member 6. In addition, a pair of locking ribs 11c is formed on the inner surface (side surface) 11b facing the circumferential direction in the groove portion 11 with an interval in the container axis O direction. In the illustrated example, the locking rib 11c is disposed in the vicinity of the upper end of the groove 11 in the container axis O direction.

The seal portion 5 has a bottomed cylindrical shape, and includes a disk-shaped bottom wall 5a and a peripheral wall 5b rising from the bottom wall 5a. The outer peripheral edge of the bottom wall 5 a is in contact with the inner peripheral edge of the top wall 8 a in the base tube 8 from below. The peripheral wall 5b is fitted to the lower end portion of the dispensing cylinder 10 from the inside in the radial direction. In the illustrated example, the lower portion of the peripheral wall 5b is fitted into the extraction tube 10, while the upper portion of the peripheral wall 5b is slightly smaller in diameter than the lower portion. A slight gap is formed between the inner peripheral surface of the dispensing cylinder 10.
The seal portion 5 of the present embodiment is a plug-like body that is liquid-tightly fitted to the spout 3.

  The operation member 6 is disposed on the radially outer side of the mounting cylinder 4 and is in contact with the container 30.

In FIG. 1, the upper end opening edge of the contact portion 12 and the upper end opening edge of the dispensing cylinder 10 are flush with each other. The lower end opening edge of the contact portion 12 is disposed above the top wall 8a of the base tube 8 with a space between the top wall 8a and the top wall 8a. An annular flange 12 a that protrudes radially outward and extends along the circumferential direction is formed on the upper portion of the outer peripheral surface of the contact portion 12 in the container axis O direction. On the upper surface of the flange 12a, a plurality of ribs 12b extending in the radial direction are formed at intervals in the circumferential direction (see FIG. 3), and between the ribs 12b adjacent in the circumferential direction in the flange 12a. It is an air replacement path.
In place of the rib 12b, for example, a portion corresponding to the rib 12b may be formed as a groove, and the groove may be used as an air replacement path.

  In FIG. 1, the push-in portion 13 has a cylindrical shape and is inserted into the dispensing cylinder 10 of the mounting cylinder 4. The pushing-in part 13 is disposed in the vicinity of the upper end part in the container axis O direction in the dispensing cylinder 10. An end surface (lower end surface) facing the lower side in the push-in portion 13 is disposed to face the upper end surface of the peripheral wall 5 b of the seal portion 5. A protrusion 13 a is formed on the lower end surface of the push-in portion 13 so that a part of the lower end surface along the circumferential direction protrudes. The tip part (lower end part) of the protruding part 13a is disposed close to the upper end surface of the peripheral wall 5b.

In FIG. 3, the protruding portion 13a is formed in an arc shape. Although not particularly illustrated, when the protrusion 13a is viewed from the radial direction, the shape of the protrusion 13a is a tapered shape or a rectangular shape in which the length in the circumferential direction gradually decreases toward the lower side. In FIG. 1, the length (projection amount) along the container axis O direction of the protruding portion 13 a is substantially equal to the length along the container axis O direction of the peripheral wall of the push-in portion 13 other than the protruding portion 13 a. It has become.

At least one of a rib and a groove extending in the container axis O direction is formed on the inner surface of the protrusion 13a facing the radially inner side.
In the present embodiment, one rib 13b that protrudes from the inner surface and extends parallel to the container axis O direction is formed on the inner surface of the protrusion 13a. The rib 13b only needs to extend in the container axis O direction, and may not be parallel to the container axis O direction. Specifically, for example, the rib 13b may extend while being inclined with respect to the container axis O direction, or may extend spirally around the container axis O. A plurality of ribs 13b may be formed.
Moreover, you may form the groove | channel extended in the container axis | shaft O direction while being depressed from the inner surface of the projection part 13a instead of the rib 13b. Moreover, you may form both these rib 13b and a groove | channel.

In FIG. 1, the rib 13 b is formed over the entire length in the container axis O direction on the inner peripheral surface of the pushing portion 13. Moreover, the lower end part of the rib 13b is formed so that the height in the radial direction gradually decreases toward the lower side. Specifically, the lower end portion of the surface facing the radially inner side of the rib 13b is gradually inclined toward the radially outer side as it goes downward. Moreover, the lower end part of the outer peripheral surface of the protrusion 13a is gradually inclined inward in the radial direction as it goes downward.
Although not particularly illustrated, the lower end portion of the rib 13b may be formed sharply so that the width in the circumferential direction is gradually narrowed toward the lower side.

  In the present embodiment, the connecting portion 14 has a shaft shape, a rod shape, or a plate shape. As shown in FIG. 1, the upper portion of the contact portion 12 in the container axis O direction (specifically, the contact portion 14). The flange 12a along the container axis O direction on the inner peripheral surface of the portion 12 and the upper end opening of the push-in portion 13 are connected in the radial direction. The length along the circumferential direction of the connecting portion 14 corresponds to the length along the circumferential direction of the groove portion 11 of the mounting cylinder 4, and the side surface of the connecting portion 14 facing the circumferential direction slides on the inner surface 11 b of the groove portion 11. It is free to move. Further, the connecting portion 14 is disposed between the pair of locking ribs 11 c along the container axis O direction in the groove portion 11.

  The lower surface of the connection part 14 is a substantially rectangular plane. Then, at the end of sliding movement of the operating member 6 with respect to the mounting cylinder 4 (downward moving end), the inner surface 11a (surface facing in the container axis O direction) of the groove portion 11 facing the connecting portion 14 side is placed on the lower surface of the connecting portion 14. Are in contact with each other.

  The lid member 7 has a top cylinder shape, covers the operating member 6 and the opening 10a of the dispensing cylinder 10 from above, and is detachably disposed in the opening 10a. The lid member 7 includes a disk-shaped top wall 7a, a peripheral wall 7b that is suspended from the outer peripheral edge of the top wall 7a, and whose outer diameter is substantially equal to the outer diameter of the flange 12a of the contact portion 12. The fitting cylinder 7c has a diameter smaller than that of 7b and hangs down from the top wall 7a and fits in the opening 10a.

The top wall 7a is in contact with the opening 10a of the dispensing tube 10 and the upper end opening of the contact portion 12 from above.
An operation piece 7d that protrudes outward in the radial direction is formed on a part of the outer peripheral surface of the peripheral wall 7b in the circumferential direction. A hinge portion 15 that connects the lid member 7 and the operation member 6 is provided on the outer peripheral surface of the peripheral wall 7b on the side opposite to the operation piece 7d with the container shaft O interposed therebetween. In the present embodiment, the lid member 7, the hinge portion 15, and the operation member 6 are integrally formed. In FIG. 1, the lower end surface of the peripheral wall 7b is in contact with the upper end surface of the rib 12b of the flange 12a.
The lower part of the outer peripheral surface of the fitting cylinder part 7c is gradually inclined inward in the radial direction as it goes downward.

Next, the procedure for refilling the contents from the refill container 1 into the main container 30 will be described with reference to FIGS.
First, the operating piece 7d is operated to rotate the lid member 7 around the hinge portion 15, and the lid member 7 is removed from the mounting cylinder 4 to expose the operating member 6 and the opening 10a of the dispensing cylinder 10. In addition, while the refill container 1 is in an inverted posture, the mouth portion 2a of the refill container 1 and the mouth portion (injection port portion) 31 of the present container 30 are arranged to face each other with the main container 30 in the upright posture. . The refill container 1 and the main container 30 are moved closer to each other in the direction of the container axis O while aligning them so that the container axes O are coaxial with each other. As shown in FIG. The refill container 1 and the main container 30 are combined by bringing the flange 12 a of the contact part 12 into contact with the opening edge of the inlet 31 of the main container 30. At this time, the refill container 1 and the main container 30 are in a state where the upper end opening of the abutting portion 12 of the operation member 6 and the opening 10 a of the dispensing cylinder 10 are inserted into the inlet 31 of the main container 30. Combined.

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.
In addition, since the spout 3 of the refill container 1 is closed by the seal portion 5, the contents in the container main body 2 do not flow out to the outside through the spout 3 even when the refill container 1 is in an inverted posture. Furthermore, since the connecting portion 14 of the operating member 6 is supported (locked) by the locking rib 11c, the sliding movement of the operating member 6 is restricted. Further, since the outer peripheral edge portion of the bottom wall 5a of the seal portion 5 is in contact with the lower surface of the top wall 8a of the base tube 8, the seal portion 5 is prevented from being opened due to the weight of the contents. .

  When the container body 2 of the refill container 1 and the main container 30 are moved relatively close to each other along the direction of the container axis O, as shown in FIG. The opening edge pushes the flange 12a of the abutting portion 12 toward the spout 3 side, and the connecting portion 14 gets over the locking rib 11c of the groove 11 so that the operating member 6 faces the spout 3 It can be slid toward the side. Then, the pushing-in part 13 of the operating member 6 presses the seal part 5 to separate it from the spout 3 and opens the spout 3. At this time, substantially the entire groove portion 11 of the dispensing tube 10 in the mounting tube 4 is inserted into the inlet 31 of the container 30.

Thereby, the inside of the container main body 2 of the refill container 1 and the inside of the inlet 31 of the main container 30 are communicated with each other through the spout 3, the push-in part 13 and the opening 10a. Therefore, the contents accommodated in the container body 2 of the refill container 1 can be poured into the inlet 31 of the main container 30, and the contents can be refilled from the refill container 1 to the main container 30. it can.
During the refilling operation, the inside of the main container 30 and the inside of the main body 2 of the refill container 1 and the outside of the containers are passed through the air replacement path (between adjacent ribs 12b) in the flange 12a of the contact portion 12. The air can be efficiently replaced, and the contents can be smoothly poured into the container 30 so that the refilling operation can be performed efficiently.
Further, even when an external force in the radial direction is applied to the mounting cylinder 4 during the refilling operation, the dispensing cylinder 10 and the contact portion of the refill container 1 are placed in the inlet 31 of the main container 30. By inserting 12, the connection state between the refill container 1 and the main container 30 is prevented from being released.

  As described above, according to the refill container 1 of the present embodiment, the refill container 1 and the main container 30 are placed in a state in which the contact portion 12 is in contact with the opening edge of the inlet 31 of the main container 30. After the combination, the contents can be refilled by a simple work of relatively moving the container body 2 and the main container 30 along the direction of the container axis O, so that the refilling work can be facilitated. .

Further, at the time of refilling, the flange 12a of the abutting portion 12 disposed radially outside the pushing portion 13 is brought into contact with the opening edge of the inlet portion 31 of the main container 30, so that the refillable container 1 is in a stable posture. In addition to being able to be combined with the main container 30, the dispensing cylinder 10 of the mounting cylinder 4 can be inserted into the inlet 31. Therefore, it is difficult to spill the contents.
Moreover, since the operation member 6 can be stabilized by making the flange 12a of the contact part 12 contact | abut to the opening edge of the injection port part 31 as mentioned above, the operation member 6 is moved smoothly. It is possible to easily open the spout 3 by pushing the seal portion 5 without requiring an excessive force.
Furthermore, since the contents can be refilled into the main container 30 simultaneously with the opening of the refill container 1, the refilling operation can be performed without placing the main container 30 in an inverted posture. Therefore, even if the contents remain in the container 30, the contents can be refilled.

Further, the contact portion 12 and the push-in portion 13 of the operation member 6 are connected by a connecting portion 14 that can move in the groove portion 11 of the mounting cylinder 4, and can be moved integrally by the connecting portion 14. The outer shape along the container axis O direction of the operation member 6 is compact while exhibiting the above-described effects.
Further, since the connecting portion 14 is inserted into the groove portion 11, the posture of the operating member 6 relative to the mounting cylinder 4 during the sliding movement is stabilized.

Moreover, since the cover member 7 that covers the operation member 6 is disposed on the dispensing tube 10 of the mounting tube 4, even if an external force is unexpectedly applied to the refill container 1 at the distribution stage or the like, the cover member 7 regulates the sliding movement of the operation member 6, and can prevent the push-in portion 13 from pushing in the seal portion 5, thereby preventing the refill container 1 from being opened unexpectedly.
In addition, by disposing the lid member 7 on the extraction cylinder 10 of the mounting cylinder 4, it is possible to prevent foreign matter from entering the extraction cylinder 10.

Further, since the lid member 7 is connected to the operation member 6 via the hinge portion 15, in the state where the lid member 7 is attached to the attachment cylinder 4 (state shown in FIG. 1), the attachment cylinder Thus, the sliding movement of the operation member 6 with respect to 4 is reliably restricted.
Further, as described in the present embodiment, the lid member 7, the hinge portion 15, and the operation member 6 can be integrally formed. In this case, the number of parts can be reduced, and the structure is simple. In addition, assembly at the time of manufacture is easy.

Further, as shown in FIG. 4, at the end of the sliding movement of the operation member 6 with respect to the mounting cylinder 4 (advance end position of the operation member 6 with respect to the mounting cylinder 4), on the inner surface 11 a facing the connecting portion 14 side in the groove portion 11, Since the connecting portion 14 is brought into contact, the following effects are obtained.
That is, as the operating member 6 slides, the connecting portion 14 of the operating member 6 comes into contact with the inner surface 11a of the groove portion 11 of the mounting cylinder 4, and therefore, when refilling, the connecting portion 14 and the inner surface 11a of the groove portion 11 It is suppressed that the content leaks out to the radial direction outer side of the pouring cylinder 10 from between.
In particular, in the present embodiment, the side surface facing the circumferential direction of the connecting portion 14 and the inner surface 11b facing the circumferential direction of the groove portion 11 are slidably contacted, and the inner peripheral surface of the contact portion 12 And the outer peripheral surface of the dispensing tube 10 are slidably in contact with each other, so that the above-described effects can be obtained more reliably.
In the example shown in FIG. 4, the end surface of the contact portion 12 facing the container body 2 side contacts the top wall 8 a of the base tube 8 in a state where the connection portion 14 contacts the inner surface 11 a of the groove portion 11. However, it is not limited to this. That is, a gap may be formed between the end surface of the contact portion 12 and the top wall 8a in a state where the connecting portion 14 and the inner surface 11a are in contact.

  Further, since the protruding portion 13a is formed on the end surface of the pushing portion 13 that faces the seal portion 5 so as to protrude from the end surface, when the pushing portion 13 pushes the sealing portion 5, the protruding portion is formed with respect to the sealing portion 5. It can be made to contact | abut from 13a, and it is made to detach | leave from the spout 3 so that the seal part 5 may incline with respect to the container axis | shaft O, and it is easy to open the spout 3 (refer FIG. 4).

  Further, since at least one of the rib 13b and the groove is formed on the inner surface of the protruding portion 13a, when the pushing portion 13 pushes the seal portion 5 and the spout 3 is opened (opened), For example, the contents in the container body 2 and the inside of the container 30 are brought into contact with the rib 13b or the groove of the protrusion 13a against the liquid surface, thereby breaking the balance of the surface tension acting on the liquid surface and making it unbalanced. This can be a trigger for starting the replacement of air with air. Accordingly, even if the viscosity of the contents is high, the contents of the container body 2 can be reliably refilled into the container 30 without clogging the spout 3.

  In addition, when the width | variety of the front-end | tip part (lower end part) of the projection part 13a is smaller than the width | variety of the base end part (upper end part) of this projection part 13a, ie, as demonstrated in this embodiment, it is protrusion. When the portion 13a is tapered (sharpened) toward the seal portion 5 side, when the push-in portion 13 pushes in the seal portion 5 and the spout 3 is opened, a protrusion is formed on the liquid level of the contents. The tip of the portion 13a is pierced so that the contents can be easily introduced toward the base end side (the main container 30 side) while spreading outside the protrusion 13a along the circumferential direction.

Moreover, the opening part 10a of the extraction | pouring cylinder 10 with which the fitting cylinder part 7c of the cover member 7 is fitted has the inner peripheral surface on the opposite side (namely, upper side) from the spout 3 along the container axis O direction. Since it gradually inclines toward the outer side in the radial direction as it goes to, the fitting tube portion 7c can be easily fitted into the opening 10a. Furthermore, since the lower portion of the fitting cylinder portion 7c is gradually inclined toward the inner side in the radial direction as it goes downward, the above-described effects can be obtained more reliably.
Therefore, the lid member 7 can be easily attached to and removed from the attachment cylinder 4.

  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 groove portion 11 is formed so that a portion along the circumferential direction of the dispensing cylinder 10 in the mounting cylinder 4 is cut out, and the connecting portion 14 of the operation member 6 is also circumferentially corresponding to this. However, the present invention is not limited to this example. That is, a plurality of groove portions 11 may be formed at intervals in the circumferential direction of the dispensing tube 10, and a plurality of connection portions 14 may be formed at intervals in the circumferential direction corresponding to this. . In this case, the rigidity of the operating member 6 is increased, and the sliding movement of the operating member 6 is more stable.

  Moreover, the groove part 11 is formed in the narrow slit shape in the extraction | pouring cylinder 10, and the connection part 14 arrange | positioned in this groove part 11 comprises shaft shape, rod shape, or plate shape corresponding to this. However, it is not limited to this. That is, for example, the groove portion 11 is formed in a rectangular notch shape (a notch widened in the circumferential direction) in the dispensing tube 10, and the connecting portion 14 is formed to extend in the circumferential direction corresponding to this. May be. In this case, even if there is only one connecting portion 14, the stability of the sliding movement of the operation member 6 relative to the mounting cylinder 4 is improved.

  Moreover, although the inner surface 11a which faces the connection part 14 side in the groove part 11 was made into the plane, and it demonstrated that the connection part 14 part contact | abutted to this inner surface 11a was also made into the plane, it is not limited to this. That is, the inner surface 11a of the groove portion 11 and the connecting portion 14 portion may be in contact with each other as long as no gap is formed therebetween. May be configured such that the concave curved surface and the convex curved surface contact each other without a gap.

  Moreover, although the seal | sticker part 5 assumed that it was a plug-like body, it is not limited to this. That is, the seal portion 5 may be any structure that can be pushed into the push-in portion 13 to open the spout 3, and therefore, for example, even if it is a film-like body that is pushed into the push-in portion 13 and can be broken. Good.

  Further, the projection 13a of the push-in portion 13 has an arc shape in plan view and is formed one in the circumferential direction. However, the shape and quantity of the projection 13a have been described in the above embodiment. It is not limited to things.

  Moreover, although the contact part 12 and the pushing-in part 13 were each making the cylindrical shape, it is not limited to this. In other words, the abutting portion 12 may be any member that is disposed on the radially outer side of the dispensing cylinder 10 of the mounting cylinder 4 and is in contact with the container 30. Any shape may be used as long as it is disposed on the radially inner side of the dispensing cylinder 10 and pushes the seal portion 5 in the direction of the container axis O along with the sliding movement of the operation member 6 to open the outlet 3. It is not limited to the shape. Examples of such a contact portion 12 include a circular arc plate shape extending in the circumferential direction. Moreover, as the pushing-in part 13, the rectangular plate shape long in a container axis | shaft O direction is mentioned, for example.

The lid member 7 described in the above embodiment is a hinge cap connected to the operation member 6 via the hinge portion 15. However, the lid member 7 covers the operation member 6 from above and is attached to the mounting cylinder 4. However, the present invention is not limited to this because it only needs to be disposed. That is, for example, the lid member 7 may be an overcap (that is, a separate body from the operation member 6) that covers the operation member 6 and the opening 10 a of the extraction tube 10 and is detachable from the mounting tube 4. .
Furthermore, instead of screwing the base tube 8 of the mounting tube 4 into the mouth 2a of the container body 2, other mounting methods such as undercut fitting (concave / convex fitting) may be employed.

  In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with well-known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.
