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.

  The present invention has been made in view of such circumstances, and its purpose is that the refilling operation can be easily performed, and it is difficult to spill the contents 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.
(1) The refill container according to the present invention has a dispensing cylinder that can be inserted into the inlet of the container and has a spout formed at the tip, and contains the contents to be refilled in the container. A container main body, a plug that closes the spout, an operation piece that connects the plug and the base end of the extraction cylinder, and is extendable in the container axial direction, The operation piece is connected to the plug body, and is connected to the first arm piece spreading radially outward as it goes downward, and to the lower end of the first arm piece via a bent portion, and downward. And a second arm piece that is narrowed radially inward as it goes and is fixed to the base end portion of the dispensing tube.

  According to the refill container according to the present invention, the container and the container main body are moved relatively close to each other along the container axial direction in a state where the extraction tube of the container main body is inserted into the inlet of the container. The pouring tube of the container body can be gradually moved toward the inside of the container. As this movement proceeds, the first arm piece spreading radially outward comes into contact with the opening edge of the inlet of the container and pushes radially inward as the dispensing cylinder of the container body moves further. It begins to move so as to be constricted.

As a result, the entire operation piece swelled in a V shape radially outwardly with the bent portion connecting the first arm piece and the second arm piece as a vertex moves radially inward, along the container axial direction. It expands while shifting to a straight extension. At this time, since the second arm piece is fixed to the proximal end portion of the dispensing cylinder, the second arm piece moves so as to be pushed out toward the dispensing port by the amount of the extension of the first arm piece. Therefore, the plug connected to the first arm piece can be separated from the spout and the closed spout can be opened (opened).
As a result, the contents in the container main body can be poured into the main container through the spout, and the refilling operation into the main container can be performed.

In particular, the contents can be easily refilled by a simple operation of relatively moving the refill container and the container along the axial direction of the container while inserting the dispensing tube into the inlet of the container. Can do.
Further, since the operation piece is fixed to the base end portion of the dispensing cylinder via the second arm piece, the external force acting radially inwardly acting on the first arm piece from the opening edge of the inlet of the container Can be efficiently converted into a force for pushing the first arm piece toward the outlet. Therefore, smooth opening can be performed by separating the plug body from the spout with less resistance.
Moreover, since the spout is closed by the stopper until the first arm piece contacts the opening edge of the inlet of the container and moves inward in the radial direction, the inside of the container body is in the stage before refilling. The contents of will not spill. Furthermore, since the contents can be refilled into this container at the same time as opening the refill container, it is possible to perform refilling work without placing the container in an inverted position. For example, when the contents in the container remain Even so, the contents can be refilled.

(2) In the refill container according to the present invention, it is preferable that a plurality of the operation pieces are provided at equal intervals around the container axis.

  In this case, when the first arm piece is pushed out to the spout side by the extension of the operation piece and the plug body is separated from the spout port, the plug body can be easily separated without being inclined. Therefore, one opening of the spout can be suppressed, and the refilling operation can be more reliably performed while the spout is sufficiently opened.

(3) In the refillable container according to the present invention, the refillable container is externally fitted to the pouring tube, can be inserted into the inlet together with the pouring tube, and moves in the container axial direction with respect to the pouring tube. A movable cylinder, the plug body is connected to the movable cylinder, and the first arm piece is connected to the movable cylinder and coupled to the plug body via the movable cylinder. Preferably it is.

In this case, the movable cylinder can be moved in the container axial direction with respect to the extraction cylinder by pushing the first arm piece toward the outlet by extension of the operation piece, and connected to the movable cylinder accordingly. The stopper can be opened away from the spout.
Thus, since the plug body can be separated from the spout via the movable cylinder, opening can be performed at a position where the spout is sufficiently inserted into the container. Therefore, refilling can be performed without spilling the contents.

(4) In the refill container according to the present invention, an engagement piece that is detachably engaged with the dispensing tube is connected to an upper end portion of the first arm piece, With the deformation of the operation piece such that the bent portion moves radially inward, it is preferable that the engagement is released by rotating radially outward about the connection portion with the first arm piece. .

In this case, when the first arm piece comes into contact with the opening edge of the inlet of the container and starts to move so as to be squeezed radially inward, the entire operation piece has a bent portion. It is deformed to move inward in the radial direction. Then, with the deformation, the engaging piece rotates outward in the radial direction around the connection portion with the first arm piece. As a result, the engagement with the dispensing cylinder can be released, and the movable cylinder becomes movable with respect to the dispensing cylinder. Therefore, from now on, the movable barrel can be moved in the container axial direction with respect to the dispensing cylinder by the extension of the operation piece by the further movement of the dispensing cylinder into the injection port, and the plug body is accordingly ejected. It can be opened away from.
In particular, since the engaging piece is engaged with the dispensing cylinder at the stage before refilling, for example, the operation piece can be prevented from being unfolded due to unexpected expansion or the like. Therefore, it is possible to effectively prevent the contents in the container body from spilling out before refilling.

(5) In the refill container according to the present invention, the movable cylinder is preferably formed with a notch recess that opens downward and in the radial direction, and the engagement piece is disposed in the notch recess.

  In this case, since the engagement piece is disposed in the notch recess, the thickness of the engagement piece can be absorbed by the notch recess, and the diameter of the portion inserted into the inlet of the container can be suppressed. Therefore, it is easy to perform the refilling operation even for the present container having a small diameter of the inlet.

  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.

It is a longitudinal cross-sectional view which shows 1st Embodiment of the refill container which concerns on this invention.

Yes. Thereby, the plug body 5 is integrally connected to the movable cylinder 6.

  In the example shown in the figure, four bridge portions 26 are formed at equal intervals in the circumferential direction. However, the present invention is not limited to this case. Moreover, the clearance gap between the bridge parts 26 adjacent to the circumferential direction functions as the distribution port 27 for distribute | circulating the contents.

(Operation piece)
As shown in FIGS. 1 to 4, the pair of operation pieces 7 are disposed so as to face each other with the container axis O interposed therebetween, and can be extended in the container axis O direction.
These operation pieces 7 have an engagement piece 30, a first arm piece 31, and a second arm piece 32, and are connected to each other to form a vertically long strip in the direction of the container axis O. The shape swells in a V shape outward in the radial direction with 36 as a vertex.

  As shown in FIGS. 1 and 2, the first arm piece 31 is a plate piece that protrudes downward from the movable cylinder 6 and spreads radially outward as it goes downward. The upper end portion of the first arm piece 31 is connected to the lower end portion of the movable cylinder 6 via the first hinge portion 35. The first hinge portions 35 are located on both sides in the circumferential direction of the cutout recess 20 formed in the movable cylinder 6 and connect the first arm pieces 31 so as to be rotatable in the radial direction.

The second arm piece 32 is connected to the lower end portion of the first arm piece 31 via a bent portion 36, and is a plate piece that squeezes radially inward as it goes downward.

  The engaging piece 30 is connected to the first arm piece 31 along with the deformation of the operation piece 7 such that the bent portion 36 moves radially inward as the first arm piece 31 moves radially inward. It is possible to release the engagement with the engagement protrusion 16 by rotating outwardly in the radial direction around the connection portion 38 (in the arrow direction shown in FIG. 3).

[Use of refill containers]
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 an upright position and the main container A is in an upright position, the refill container 1 is placed above the main container A, and as shown in FIG. The refill container 1 and the main container A are combined in a state where the extraction cylinder 3 and the movable cylinder 6 of the container body 2 are integrally inserted into the inlet A1.

  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.

  Next, the refill container 1 and the main container A are moved relatively close to each other in the direction of the container axis O, and the pouring cylinder 3 and the movable cylinder 6 of the container main body 2 are moved downward so as to be inserted inside the main container A. And if this movement is advanced, the 1st arm piece 31 which spreads to the radial direction outer side will contact the opening edge of injection port A1 of this container A, and further of the extraction | pouring cylinder 3 and the movable cylinder 6 of the container main body 2 Along with the movement, it is pushed radially inward and begins to move so as to be constricted. Thereby, the whole operation piece 7 is deformed such that the bent portion 36 moves radially inward.

Thereby, the engagement piece 30 can be rotated radially outward centering on the connection part 38 with the 1st arm piece 31 (refer FIG. 3), and engagement with respect to the extraction pipe | tube 3 can be cancelled | released. .
Specifically, the engaging claw 30 a formed at the upper end of the engaging piece 30 is separated from the dispensing cylinder 3 by the engaging piece 30 turning radially outward about the connection portion 38. And the engagement with the engagement protrusion 16 can be released. And by releasing this engagement, the movable cylinder 6 becomes movable with respect to the dispensing cylinder 3 downward.

By the way, when the first arm piece 31 moves so as to squeeze inward in the radial direction by contact with the opening edge of the injection port A1, the bent portion 36 connecting the first arm piece 31 and the second arm piece 32 is apex. As shown in FIG. 6, the entire operation piece 7 swelled in a V shape outward in the radial direction moves inward in the radial direction and extends while shifting to a state of extending straight along the container axis O direction. .
Since the 2nd arm piece 32 is being fixed to the ring 13 at this time, it moves so that it may be extruded to the spout 4 side by the part which the 1st arm piece 31 expanded. Therefore, the movable cylinder 6 connected to the first arm piece 31 can be moved downward with respect to the dispensing cylinder 3.

  Thereby, the plug body 5 connected to the movable cylinder 6 can be separated downward from the spout 4 and the closed spout 4 can be opened (opened). As a result, the contents in the container main body 2 can be poured into the main container A through the spout 4, the distribution port 27, and the movable cylinder 6, and the refilling operation into the main container A can be performed. .

  When the movable cylinder 6 is moved downward with respect to the dispensing cylinder 3 of the container body 2, the second lateral rib 21 engages with the first lateral rib 15 from above. Thereby, the further downward movement of the movable cylinder 6 can be restricted, and for example, an excessive load can be prevented from acting on the operation piece 7 extending straight.

In particular, the refill container 1 and the main container A are moved relatively close to each other along the container axis O direction while inserting the dispensing cylinder 3 and the movable cylinder 6 of the main body 2 into the injection port A1 of the main container A. The work of refilling the contents can be easily performed by a simple operation.
Further, since the operation piece 7 is connected to the ring 13 fixed to the base end portion of the dispensing cylinder 3 via the second arm piece 32, the first arm extends from the opening edge of the inlet A1 of the container A. The external force inward in the radial direction that has acted on the piece 31 can be efficiently converted into a force that pushes the first arm piece 31 toward the spout 4 side. Therefore, the stopper 5 can be separated from the spout 4 with less resistance and can be smoothly opened.

  In addition, the spout 4 is blocked by the plug 5 until the first arm piece 31 contacts the opening edge of the inlet A1 of the main container A and moves radially inward as shown in FIG. Therefore, the contents of the container body 2 are not spilled before the refill. Furthermore, since the contents can be refilled into the main container A simultaneously with the opening of the refill container 1, it is possible to perform the refilling operation without placing the main container A in an inverted posture, for example, the contents in the main container A remain. Even if it is, it is possible to refill the contents.

  Further, since the plug body 5 is separated from the spout 4 via the movable cylinder 6, the opening can be performed with the spout 4 fully inserted into the container A as shown in FIG. Therefore, refilling can be performed without spilling the contents.

Further, as shown in FIG. 5, since the engagement piece 30 is engaged with the dispensing cylinder 3 at the stage before refilling, for example, the operation piece 7 is unexpectedly extended, and the opening is performed. This can be suppressed. Therefore, it can suppress effectively that the contents of the container main body 2 are spilled in the stage before refilling.
Furthermore, since the engagement piece 30 is disposed in the notch recess 20, the thickness of the engagement piece 30 can be absorbed by the notch recess 20, so that the diameter of the portion inserted into the injection port A1 of the container A is increased. Can be suppressed. Therefore, even if the container A has a small diameter of the inlet A1, the refilling operation is easy to perform.

In addition, in the said 1st Embodiment, although the upper end part of the 1st arm piece 31 and the lower end part of the movable cylinder 6 were connected via the 1st hinge part 35, it is not limited to this case. For example, the engagement piece 30 arranged in the notch recess 20 and the peripheral edge 20b in the notch recess 20 may be connected via a connecting part. At this time, the engagement piece 30 may be connected to one of the peripheral end edges 20b. Moreover, you may connect the operation piece 7 and the movable cylinder 6 with another method.
Furthermore, although it engaged so that the engagement protrusion 16 might be pinched | interposed between the upper end edge 20a of the notch recessed part 20, and the engagement nail | claw part 30a formed in the engagement piece 30, it is not limited to this case. For example, the engagement piece 30 may be engaged by providing an engagement hole into which the engagement protrusion 16 is fitted.

Second Embodiment
Next, a second embodiment according to the present invention will be described.
The difference from the first embodiment is that, in the first embodiment, the mouth portion of the container body is used as a dispensing cylinder, and the refilling container is a type in which the dispensing cylinder and the container body are integrated. In the embodiment, the dispensing cylinder is attached to the mouth portion of the container body via the attachment cylinder, and the dispensing cylinder is a refill container of a type separate from the container body.
Furthermore, in the first embodiment, the operation piece and the plug are connected via the movable cylinder, but in the second embodiment, the plug and the operation piece are directly connected.

  In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

[Configuration of refill container]

And a flange portion 46. The dispensing tube 3 has a lower end connected to the radially inner edge of the flange 46. A seal tube 47 that fits inside the mouth portion 41 of the container body 2 is suspended from the flange portion 46, and seals between the mouth portion 41 and the mounting tube 42 in a liquid-tight manner, for example.

  In the illustrated example, the outer cylindrical portion 45 is undercut fitted to the mouth portion 41 of the container body 2, but the present invention is not limited to this case, and may be attached by screwing or the like. In any case, the mounting cylinder 42 may be mounted on the mouth portion 41 of the container body 2.

  The plug body 5 of the present embodiment is provided with a bottomed cylindrical plug body 25 fitted inside the reduced diameter portion 3a of the dispensing cylinder 3 and the plug body 25, and the reduced diameter portion 3a. And an annular flange plate 50 that overlaps with the opening edge of each other. Thereby, the plug 5 seals the spout 4 in a liquid-tight manner, for example.

  Further, the operation piece 7 of the present embodiment does not include the engagement piece 30 in the first embodiment, and the upper end portion of the first arm piece 31 is directly connected to the flange in the plug body 5 via the first hinge portion 35. It is connected to the outer peripheral edge of the plate 50. The lower end portion of the second arm piece 32 is connected to an annular ring body 51 formed integrally with the base end portion of the dispensing cylinder 3 via the second hinge portion 37.

[Action of refill container]
Even in the case of the refill container 40 configured in this way, the first arm piece 31 moves so as to squeeze radially inward due to contact with the opening edge of the injection port A1 as in the first embodiment. By doing so, the whole operation piece 7 extends while shifting to a state of extending straight along the container axis O direction. Accordingly, the first arm piece 31 can be moved so as to be pushed out toward the spout 4 by the extended amount, and the plug body 5 connected to the first arm piece 31 can be separated from the spout 4.
As a result, the closed spout 4 can be opened (opened), and the contents in the container body 2 can be poured into the main container A and refilled.

  The technical scope of 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, the container main body 2 and the main container A may be formed thinly so as to be squeezable and refilling may be performed while the squeeze is deformed.
Moreover, although it was set as the structure which provided the operation piece 7 as a pair, it is not limited to a pair, You may provide only 1 or 3 or more.
