Description

  The present invention relates to a refill container.

  Conventionally, as this type of refill container, as described in, for example, Patent Document 1 below, a container body that contains the contents to be refilled in this container and a mouth portion of the container body are mounted, and the mouth portion is closed. There is known a refill container that is refilled in a state in which the inner plug is screwed to the mouth of the container. The inner plug is formed with a spout for pouring out the contents and a seal portion for closing the spout. The seal portion is made of, for example, a lid provided with a pull top.

  In the above-mentioned refill container, first, the pull top is pulled up to open the spout of the inner plug. Subsequently, the refill container is placed in an upright position (the mouth is in an upward position), and the mouth of this container in an inverted position (the mouth is in a downward position) is screwed onto the inner plug of the refill container. To do. 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 into 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 it is necessary to turn the refill container and the main container upside down. Refilling 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.
On the other hand, contrary to the above-described conventional example, in the refill container for refilling the contents by inserting the dispensing tube of the refill container into the inlet of the main container, there are various types of the refillable container, and the inner diameter of the mouth portion (Hereinafter referred to as “caliber”) is not uniform for all the containers, so there is play between the refill container and the container due to the wide variety of calibers of the container. Occur. When looseness (play) occurs between the refill container and the main container, the inverted position of the refill container is not stable, and the refill container may be accidentally tilted during the refill operation as in the conventional example.
Therefore, the present invention has been made in view of the above-described problems of the prior art, and can be easily refilled, and it is difficult to spill contents during refilling, and the contents in the container remain. The refilling operation can be performed even when the refilling operation is performed, and the backlash between the refilling container and the container due to the wide variety of the caliber of the container can be suitably absorbed to perform the refilling process smoothly. It aims to provide a refillable container that can be used.

Among the present invention for solving the above technical problem, the means of the invention according to claim 1 includes a container main body in which contents to be refilled in the container are stored, and the container along the container axial direction from the container main body. A pour cylinder that extends toward the outside of the main body, can be inserted into the inlet of the main container, and has a spout formed at the tip, and closes the spout outlet. A refill container comprising a closing plate connected to a peripheral edge portion of the opening through a weakened portion that can be broken, and an operation protrusion connected to the closing plate,
The operation projecting piece is provided at one end of the operation piece and the other end of the projecting piece main body, the other end of which is connected to the outer side in the radial direction of the extraction tube. A hook portion that engages with an opening edge of the inlet of the main container, and in the refill container, the outer peripheral surface of the extraction tube is oriented radially outward with respect to the container axial direction, and A deformable blade is provided.

In the above-described configuration according to claim 1, the hooking portion disposed on the radially outer side of the pouring tube is engaged with the opening edge of the pouring port of the container, and the pouring tube is made to the pouring port of the container. Can be placed face to face. Therefore, by moving the container body and the main container relatively closer along the container axial direction, the dispensing tube can be moved so as to be inserted into the inner side of the main container. At this time, since the hook portion is engaged with the inlet of the container, the protruding piece body gradually becomes tensioned with the movement of the pouring cylinder to the inside of the container, and the protruding piece body is gradually A tensile force can be applied relatively to the closing plate via the.
Therefore, the blocking plate can be gradually deformed while breaking the weakened portion, and the closed spout can be opened. As a result, the contents in the container main body can be poured into the main container through the spout and can be refilled into the main container.
Further, when the dispensing cylinder is inserted into the inlet of the container, the blades oriented in the above-described manner on the outer peripheral surface of the dispensing cylinder are deformed according to the gap between the outer surface of the dispensing cylinder and the container inlet. In order to closely fit the gap, the play (play) between the refill container and the main container is suitably absorbed, and the inverted position of the refill container is stabilized. That is, when the diameter of the container is small, the slats are greatly deformed to fit into the gap between the outer peripheral surface of the extraction cylinder and the container inlet, while when the diameter of the container is large, the slats are deformed small. Then, it fits into the gap between the outer peripheral surface of the dispensing tube and the inlet of the main container and suitably absorbs play (play) between the refill container and the main container. This allows the refill container to be turned upside-down while the container body and the main container are moved relatively close to each other in the axial direction of the container since the hook portion of the operation protrusion engages with the opening edge of the main container inlet. Becomes stable and the refilling operation can be performed smoothly.

  According to a second aspect of the present invention, there is provided an upright wall in which a part of a side wall extends along the container axial direction at an upper end portion of the pouring tube, and the blade plate is formed of the standing wall and the pouring tube. It is that it is provided along the outer peripheral surface of both.

  In the above configuration, since the length of the blade plate in the container axial direction can be ensured long, the container main body, the container, and the container from the time when the hook portion of the operation protruding piece engages the opening edge of the container inlet. The blades can absorb the play (play) between the refill container and the main container, and the inverted position of the refill container can be stabilized while the container moves relatively close along the container axial direction. .

  According to a third aspect of the present invention, the standing wall is provided on the opposite side of the hook portion with respect to the container shaft.

  In the above configuration, since the blades can be provided symmetrically with respect to the hook portion with respect to the container axis, the container main body and the container The blades can absorb the play (play) between the refill container and the main container, and the inverted position of the refill container can be stabilized while the container moves relatively close along the container axial direction. .

  According to a fourth aspect of the present invention, the blades are provided symmetrically with respect to the bisector of the hook portion passing through the container shaft.

  In the above configuration, since the blades can be provided equally with respect to the container shaft, the container body and the container are connected to the container shaft from the time when the hook portion of the operation protrusion is engaged with the opening edge of the container inlet. While the blades move relatively close to each other in the direction, the slats preferably absorb the play (play) between the refill container and the main container, and the inverted position of the refill container can be stabilized.

  According to the present invention, the refilling operation can be easily performed, the contents are not easily spilled at the time of refilling, and the refilling operation can be performed even when the contents in the container remain. At the same time, it is possible to absorb the play (play) between the refill container and the main container due to the wide variety of calibers of the main container and to smoothly perform the refilling operation.

In the illustrated example, the cylinder main body 11 is screwed into the mouth portion 2a of the container main body 2. However, the present invention is not limited to this case, and may be attached by undercut fitting or the like. In any case, the mounting cylinder 10 only needs to be mounted on the mouth 2a of the container body 2.

  The dispensing cylinder 3 has a smaller diameter than the inner diameter of the inlet A1 of the main container A, and the upper end opening surface where the spout 3a opens extends along a horizontal plane perpendicular to the container axis O. In addition, although the extraction | pouring cylinder 3 of this embodiment is a cross-sectional polygonal shape (half-moon shape), you may form in a cross-sectional circular shape or a rectangular shape. In the present embodiment, as described above, the upper end opening surface of the dispensing cylinder 3 extends along a horizontal plane orthogonal to the container axis O, but obliquely inclined with respect to the container axis O. You may extend along an inclined surface.

  The obstruction | occlusion board 4 is connected via the weakened part 30 which can be fractured | ruptured to the opening peripheral part of the spout 3a. The closing plate 4 is formed thinner than the thickness of the dispensing tube 3 and can be deformed (for example, elastically deformable). The front and back surfaces of the closing plate 4 are orthogonal to the container axis O.

  The operation projecting piece 5 has a projecting piece main body 20 whose one end 20 a is connected to the closing plate 4 and whose other end 20 b is disposed on the radially outer side of the dispensing tube 3, and the other end of the projecting piece main body 20. And a hook portion 21 formed so as to project from the lower end side surface of 20b in a substantially L shape in the radial direction. The hook portion 21 in the present embodiment forms an opening portion that is open upward with respect to the lower end portion of the other end portion 20b. That is, the hook portion 21 forms an opening portion that opens upward in cooperation with the other end portion 20b.

One end 20a of the projecting piece main body 20 is connected to the closing plate 4 at a position radially outward from the center point of the closing plate 4 through which the container axis O passes. The other end 20b of the projecting piece main body 20 is
On the opposite side of the container shaft O from the side where the end plate 20a is connected to the closing plate 4, it is arranged on the outer side in the radial direction of the dispensing tube 3, and further connected to the closing plate 4 of the end portion 20a. It is arranged below the position.
That is, in the present embodiment, the one end 20a and the other end 20b of the projecting piece main body 20 are separately arranged at positions opposite to each other with the container shaft O in between, and the other end 20b is lower than the one end 20a. (Arranged closer to the inside of the container body 2 along the container axis O direction).

Here, in this embodiment, a part of the outer peripheral edge portion of the closing plate 4 is connected to the opening peripheral edge portion of the spout 3a via a connecting portion 31 that can be bent and deformed, and the rest is broken. They are connected via a possible weakening 30.
The connecting portion 31 is formed on the opposite side of the container shaft O with respect to the side where the one end portion 20a is connected to the closing plate 4 and at a position facing the connecting position in the radial direction. On the other hand, the weakening part 30 exhibits C shape by container axis | shaft O direction view.
Further, a standing wall 33 extending upward along the container axis O direction is formed at a position radially outward of the connection position of the end portion 20a with the closing plate 4 at the opening peripheral edge of the spout 3a. ing. Therefore, the cross-sectional shape of the standing wall 33 is the same shape as a part of the side wall cross-section of the extraction tube 3.

The hook portion 21 has a width along the circumferential direction that is substantially the same size as the protruding piece body 20, and is connected to the outer peripheral surface of the extraction tube 3 via a breakable bridge portion (connecting portion) 22. Are connected.

  On the outer periphery of the lower end portion of the dispensing cylinder 3, a rib 44 is provided that forms a displacement upper surface 44a that is displaced upward with respect to the upper surface of the flange portion 13 of the mounting cylinder 10. The rib 44 has a plate shape substantially orthogonal to the circumferential direction, and is provided at a position opposite to the hook portion 21 in the radial direction, and is also provided at a position shifted by 90 ° from both ends in the circumferential direction.

  And in the refill container 1 of this embodiment, the two slats 6 orientated radially outward along the outer peripheral surface of both the standing wall 33 and the extraction pipe | tube 3 are provided. This vane plate 6 is deformed according to the diameter of the main container A injection port A1 and fits into the gap between the outer peripheral surface of the extraction tube 3 and the inner peripheral surface of the injection port A1 of the main container A. 3 and the container A are preferably absorbed, and when the hook portion 21 is engaged with the opening edge of the inlet A1 of the container A, the dispensing cylinder 3 moves through the inlet A1 of the container A. During the relatively close movement along the container axis O direction, the inverted posture of the refill container 1 is stabilized. The deformation referred to here means, for example, bending deformation, torsional deformation, buckling deformation, or elastic deformation or plastic deformation combining them. Accordingly, the plate thickness and hardness of the blade plate 6 are such that the blade plate 6 can be deformed according to the diameter of the container A injection port A1 when the dispensing tube 3 is inserted into the container A injection port A1. Thickness and hardness. That is, when the diameter of the main container A injection port A1 is small, the vane plate 6 is deformed as described above and fits into the gap between the outer peripheral surface of the extraction tube 3 and the inner peripheral surface of the injection port A1 of the main container A, and the diameter is When it is large, the blade 6 has a suitable hardness that can be securely rattled.

  Hereinafter, a method for refilling the contents from the refill container 1 into the main container A will be described with reference to FIGS. FIG. 3 is a diagram for explaining a refilling operation between the main container having a large diameter and the refilling container 1, and FIG. 4 is a diagram for explaining a refilling operation between the main container having a small diameter and the refilling container 1. FIG. 5 is a view showing a state after opening the refill container 1 in FIG.

  First, as shown in FIGS. 3 and 4, after the refill container 1 is placed above the container A with the refill container 1 in the inverted posture and the main container A in the upright posture, The refill container 1 and the main container A are combined face to face while the hook portion 21 provided on the piece main body 20 is engaged with the opening edge of the inlet A1 of the main container A.

  In addition, by setting the refill container 1 in the inverted posture as described above, the top and bottom of the refill container 1 are inverted, and in the refill container 1 in the inverted posture, the side of the dispensing cylinder 3 along the container axis O direction is the lower side. The container body 2 side is the upper side. Further, in the refill container 1, when the hook portion 21 is engaged with the opening edge of the injection port A1 of the main container A, the pouring piece body 3 and the projecting piece main body 20 of the operation projecting piece 5 are both in the injection port A1. The dimension is set so as to be accommodated in the radially inner side.

  When the diameter of the inlet A1 of the main container A is large (FIG. 3), the deformation (inclination along the circumferential direction) of the blade plate 6 is small, while the diameter of the inlet A1 of the main container A is small. In the case (FIG. 4), the deformation (inclination along the circumferential direction) of the blade 6 becomes large.

Subsequently, with the hook portion 21 engaged, the refill container 1 and the main container A are moved relatively close to each other in the container axis O direction, and the weakening portion 30 (see FIG. 2) is broken. The outlet tube 3 is moved downward so as to be inserted inside the container A. Note that immediately after the refill container 1 and the main container A are moved relatively close to each other in the container axis O direction, the bridge portion 22 described above is broken.

When the refill container 1 and the main container A are moved relatively close to each other in the direction of the container axis O as described above, the hook portion 21 is engaged with the opening edge of the inlet A1, so this refill is performed. In the container 1, the protruding piece main body 20 is gradually stretched with the movement of the pouring cylinder 3 to the inside of the container A, and gradually becomes relatively relative to the closing plate 4 via the protruding piece main body 20. A tensile force can be applied.
Therefore, the closing plate 4 can be gradually deformed so that the weakened portion 30 is broken by the tensile force applied to the operation protrusion 5 along with the movement of the dispensing cylinder 3 to the inside of the container A. ,
The closed spout 3a can be opened.
As a result, as shown in FIG. 5, the contents in the container main body 2 can be poured into the main container A through the spout 3a, and the main container A can be refilled. At this time, the flange portion 13 and thus the refill container 1 are supported by the bottom wall portion of the hook portion 21 and the three ribs 44 on the opening edge of the inlet A1 at an equal interval of approximately 90 ° in the circumferential direction. Stabilize the refill container 1.

Thus, in the refill container 1 according to the present embodiment, in particular, a simple operation of relatively moving the refill container 1 and the main container A along the container axis O direction while engaging the hook portion 21. Since the contents can be refilled, the refilling work is facilitated.
Further, since the inside of the dispensing tube 3 is not opened until the container body 2 and the main container A are relatively moved along the container axis O direction, the container body 2 is in a stage before refilling. The contents inside are not spilled.
Moreover, since the contents are refilled into the main container A at the same time as the refill container 1 is opened, the refilling operation can be performed without placing the main container A in an inverted position, and the contents in the main container A remain. Even if it is, it can refill the contents.

  Furthermore, the slat 6 fits into the gap between the outer peripheral surface of the dispensing cylinder 3 and the inner peripheral surface of the inlet A1 of the main container A, and suitably absorbs the play between the refill container 1 and the main container A, Since the hook portion 21 is engaged with the opening edge of the injection port A1 of the main container A, the dispensing cylinder 3 moves relatively closer along the container axis O in the injection port A1 of the main container A. Meanwhile, the inverted posture of the refill container 1 is stabilized.

Moreover, in the refill container 1 which concerns on this embodiment, since a part of outer peripheral part of the obstruction board 4 is connected to the extraction pipe | tube 3 via the connection part 31 which can be bent and deformed, it becomes weak. Even after the portion 30 is broken, it is possible to maintain the closed plate 4 and the dispensing cylinder 3 in a connected state.
Thereby, the content in the refill container 1 can be smoothly poured out from the spout 3a, stabilizing the relative positions of the main container A and the refill container 1.

  Moreover, since the hook part 21 forms the opening part opened toward the outer side of the container main body 2 along the container axis | shaft O direction, and the said opening part engages with the opening edge of injection port A1, it is hooked. The engagement between the portion 21 and the opening edge of the inlet A1 is more reliably achieved.

Although one embodiment of the present invention has been described above, 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, as shown in FIG. 6A, the slats 6 may be provided only along the outer peripheral surface of the extraction tube 3, and as shown in FIG. 6B, the standing wall 33 is extended in the circumferential direction. Then, three or more blades 6 may be provided.

For example, the container main body 2 may be formed to be thin so as to be squeezable, and the refilling operation may be performed while the squeeze is deformed.
In the above embodiment, the example in which the dispensing cylinder 3 is screwed to the container body 2 has been described. However, the dispensing cylinder 3 may be formed integrally with the container body 2. The container body 2 may be a container such as a tube container.

  Moreover, in the said embodiment, although the hook part 21 was formed in the substantially L shape, it is not limited to this shape. For example, the hook portion may be a flange-shaped portion that is formed only by a portion extending radially outward from the other end portion 20b. In this case, when the hook portion engages with the opening edge of the inlet A1, movement toward the radially inner side is difficult to be regulated, but manufacturing is facilitated. The hook portion may be arcuate.

  The refill container of the present invention is suitably applied to a refill container in which the contents are refilled by inserting the dispensing tube into the inlet of the container.
