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 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 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 conventional refill container described above, 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.

  The present invention has been made in view of such circumstances, and can be easily refilled, and it is difficult to spill contents during refilling, and the contents in the container remain. Even so, an object is to provide a refill container that can be refilled.

In order to achieve the above object, the present invention provides the following means.
The refill container according to the present invention includes a container main body in which contents to be refilled in the main container are accommodated, and extends from the mouth of the container main body toward the outside of the container main body along the container axial direction. A pouring tube that can be inserted into the inlet of the container and has a spout formed at the tip thereof, and is connected to the opening peripheral edge of the spout through a weakened portion that can be broken. A closing plate provided, and an operation projection piece continuous with the closure plate, the operation projection piece opening toward the outside of the container body along the container axial direction, A hook portion that engages with an opening edge of the inlet, and a projecting piece body that connects the closing plate and the hook portion, the projecting piece body having one end connected to the closing plate and the other A locking portion having an end abutting on or close to the opening edge of the dispensing tube; It is characterized in that it comprises a parts and connecting pieces for connecting the hook portion.

According to the refill container according to the present invention, the hook portion that opens toward the outside of the container body along the container axial direction is formed on the protruding piece body. While being locked to the edge, the dispensing cylinder can be arranged facing the inlet of the container. 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 locked to the main container, the protruding piece main body is gradually stretched with the movement of the dispensing pipe to the inner side of the main container, and the protruding piece main body is gradually locked. A tensile force can be applied to the closing plate via the portion.
Therefore, the weakened portion can be broken while the closing plate is deformed or displaced, 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.

As described above, the contents can be refilled by a simple operation of relatively moving the refill container and the main container along the container axial direction while the hook portion is locked to the main container.
Moreover, even after the hook portion is locked to the main container, the spout is blocked by the closing plate until the main body and the main container are relatively moved along the container axial direction. In the stage before refilling, the contents in the container body will not spill.
Furthermore, since the refilling operation is performed on the unopened refill container in the inverted posture without placing the container in the inverted posture, for example, even if the content in the container remains, the content is refilled. be able to.

  Further, according to the refill container of the present invention, the other end of the locking portion of the projecting piece main body is disposed on the opening edge of the dispensing cylinder, so that the force applied to the operation projecting piece by the fall of the refill container ( (Impact force) is transmitted to the dispensing tube via the locking portion, and the impact force can be received by the dispensing tube. Therefore, it is possible to suppress the impact force applied to the operation protrusion from being transmitted to the closing plate, and it is possible to prevent the closing plate from being opened or the operation protrusion from being damaged.

  In addition, since there is no separate member separate from the operation protrusions around the spout of the spout cylinder, the contents are not attached to such a separate member, and the refilling operation is performed without polluting the spout. It can be performed. In the case of contents with particularly high viscosity, if another member is provided at the spout, the contents will be attached to the other member, and all the contents cannot be refilled into this container. In the invention, since there is no such separate member, the contents can be refilled without waste.

  Moreover, in the refill container which concerns on this invention, it is preferable that the said connection piece is provided in a row by the other end of the said latching | locking part.

  In this case, the other end of the locking portion located on the opening edge of the dispensing cylinder and the connecting portion of the connecting piece with respect to the locking portion are provided at the same position in a top view as viewed from the container axial direction. Therefore, the impact force applied to the connecting piece of the projecting piece main body due to dropping of the refill container or the like can be efficiently transmitted to the dispensing cylinder via the locking portion.

  According to the refill container of 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.

  Next, a method for refilling the contents from the refill container 1 configured as described above into the main container A will be described.

First, after the refill container 1 is placed in the upright posture and the refill container 1 is placed above the main container A in the upright position, as shown in FIG. The refill container 1 and the main container A are combined while the hook portion 21 is locked to the opening edge of the inlet 1A of the main container A. At this time, the projecting piece main body 20 enters the injection port 1A, the projecting portion 15 is located above the opening edge of the injection port 1A, and a part of the flange portion 13 is a connecting portion 21b of the hook portion 21. It is located above.
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.

Subsequently, the refill container 1 and the main container A are moved relatively close to each other in the direction of the container axis O while the hook part 21 is held in the main container A, and the bridge part 24 is broken while being poured out. The cylinder 3 is moved downward so as to be inserted inside the container A. At this time, since the hook portion 21 is locked to the main container A, the connecting piece 22 of the projecting piece main body 20 is gradually stretched along with the movement of the extraction tube 3 to the inner side of the main container A. Gradually, a tensile force can be applied to the closing plate 4 via the locking portion 23 of the projecting piece body 20.
Therefore, as shown in FIG. 4, the closing plate 4 can be deformed or displaced toward the opposite side of the locking portion 23 that sandwiches the container shaft O in the radial direction while breaking the weakened portion 40. The spout 3a can be opened. As a result, the contents in the container main body 2 can be poured into the main container A through the spout 3a, and refilling into the main container A can be performed.

Enter the gap between the inner peripheral surface.

  In a state where the dispensing tube 3 is completely inserted into the inlet 1A of the container A, that is, in a state where the connecting portion 21b of the hook portion 21 is in contact with the flange portion 13, the upper end of the bumping protrusion 15 and the hook portion 21 Since the connecting part 21b is set at the same height, the inverted posture of the refill container 1 relative to the main container A can be stabilized. Therefore, the contents of the refill container 1 can be poured into the main container A from the beginning of the refill with the refill container 1 in a stable inverted posture without rattling.

According to the refill container according to the present embodiment described above, the refill container 1 and the main container A are relatively moved along the container axis O direction with the hook portion 21 being locked to the main container A. The contents can be refilled by a simple operation.
Moreover, even after the hook portion 21 is locked to the main container A, the spout 3a remains the closing plate until the main body 2 and the main container A are relatively moved along the container axis O direction. Since it is obstruct | occluded by 4, the content in the container main body 2 does not spill in the stage before refilling.
Furthermore, since the refilling operation is performed on the unopened refill container in an inverted posture without placing the main container A in the inverted posture, for example, even if the contents in the main container A remain, the refill operation of the contents It can be performed.

  Moreover, according to the refill container 1 of this embodiment, since the other end 23b of the latching | locking part 23 of the protrusion piece main body 20 is arrange | positioned on the opening edge 3b of the extraction pipe | tube 3, fall of the refill container 1 etc. Thus, the force (impact force) applied to the operation projection piece is transmitted to the extraction tube 3 through the locking portion 23, and the impact force can be received by the extraction tube 3. For this reason, it is possible to suppress the impact force applied to the operation projection piece 5 from being transmitted to the closing plate 4 and to prevent the closing plate 4 from being opened or the operation projection piece 5 from being damaged.

  Moreover, since a member different from the operation protrusion 5 is not separately provided around the spout 3a of the spout cylinder 3, the contents are not attached to such a separate member, and the spout 3a is soiled. The refilling work can be done without In particular, in the case of a highly viscous content, if the separate member is provided in the spout 3a, the content is attached to the separate member, and the entire content cannot be refilled into the container A. However, in this embodiment, since there is no such separate member, the contents can be refilled without waste.

  Moreover, in the refill container 1 of this embodiment, the other end 23b of the latching | locking part 23 located on the opening edge 3b of the extraction | pouring cylinder 3, and the connection part (base end part 22b) with respect to the latching | locking part 23 of the connection piece 22 are shown. ) Are provided at the same position in a top view as viewed from the container axis O direction, and the impact force applied to the connecting piece of the projecting piece main body 20 due to the drop of the refill container 1 or the like is efficiently transmitted through the locking portion 23. Therefore, it can be transmitted to the dispensing cylinder 3.
