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 refill container described above, the pull top is first lifted 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 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 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.
Also, 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 will spill. There was a risk of getting 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 solve the above problems, the present invention proposes 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 main container body along the container axial direction. A pour cylinder in which a pair of spouts are formed which can be inserted into the injection port and open toward the outside in the radial direction perpendicular to the axial direction of the container; A closing plate connected to the opening edge of the outlet via a breakable weakening portion, and a pair of operation protrusions separately connected to the closing plate, each of the operation protrusions being closed at one end. A protruding piece body connected to a plate and having a hook portion formed at the other end thereof for engaging with an opening edge of the inlet of the container, and the pair of spouts are arranged around a container axis. The opening width along the direction is different from each other

According to this configuration, since the hook portion is formed at the other end portion of the projecting piece body, the dispensing tube is connected to the inlet of the main container while engaging the hook portion with the opening edge of the inlet of the main container. Can be placed facing each other. 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, the projecting piece main body is gradually stretched along with the movement of the pouring cylinder to the inside of the container, and gradually, with respect to the closing plate via the projecting piece main body. Relatively tensile force can be applied.
As a result, 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.

  In this case, the contents can be easily refilled by a simple operation of relatively moving the refill container and the main container along the container axial direction while engaging the hook portion. In addition, since the spout is closed by the closing plate until the container body and the main container are relatively moved along the container axial direction, the contents in the container body may be spilled before refilling. Absent. Furthermore, since the contents can be refilled into the main container at the same time as opening the refill container, it is possible to perform refilling work without placing the main container in an inverted position, for example, when the contents in the main container remain. Even so, the contents can be refilled.

Here, according to the configuration of the present invention, since the spout is open toward the outside in the radial direction, the contents poured out from the spout are poured out toward the inner wall of the container during the refilling operation. It becomes easy to be done, and it can suppress that the contents foam or bounce in this container.
Further, since the opening widths along the circumferential direction of the pair of spouts are different from each other, the contents are positively poured out from the spout having a large opening width. Therefore, among the spouts, a spout with a small opening width is likely to have a gap between the opening edge and the contents, and the air replacement between the inside of the container and the container body is efficiently performed through this gap. Can do. Therefore, the contents in the container body can be smoothly poured out into the container, and the refilling operation can be performed efficiently.

  Further, the pair of spouts may extend from the distal end portion of the spout tube toward the inside of the container body along the container axial direction.

  In this case, since the spout extends from the tip of the spout tube toward the inside of the container main body along the container axial direction, the direction in which the weakened portion that connects the spout and the closing plate extends. The direction in which the refill container and the main container are moved relatively close to each other at the time of refilling coincides with each other. Therefore, in a state where the refill container and the main container are combined, when the refill container and the main container are moved relatively close to each other in the axial direction of the container, power is efficiently applied to the weakened portion. Opening operability can be provided.

  In addition, a flange portion is formed on the proximal end portion of the dispensing tube so as to project outward in the radial direction and is disposed on the opening edge of the mouth portion. Of the flange portions, With a relative approaching movement along the container axial direction of the refill container and the main container in a state where the extraction tube is inserted into the injection port at a position different from the operation projecting piece in the circumferential direction, A contact portion that can contact the opening edge of the injection port may be formed.

In this case, the container body and the main container are moved relatively close to each other in the axial direction of the container, and the contact portion is brought into contact with the opening edge of the inlet, so that the posture of the refill container with respect to the main container is more stable. The contents can be made difficult to spill.
Also, during the refilling operation, the air exchange between the inside and the outside of the container is efficiently performed through the gap between the portion other than the contact part in the flange part and the opening edge of the inlet of the container. Can do. Therefore, the contents can be smoothly poured into the container, and the refilling operation can be performed efficiently.

  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.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1-3, the refill container 1 of this embodiment is equipped with the bottomed cylindrical container main body 2 in which the content is accommodated, From this container main body 2, the separate main container 100 is provided. The contents are refilled (see FIG. 5 and subsequent figures).

  As shown in FIGS. 1 to 4, the refill container 1 of the present embodiment can be inserted into the container body 2 and the inlet 101 (see FIG. 5 and subsequent figures) of the container 100 described above, and a pair of spouts. 3a, 3b (see FIG. 4) formed top tube-shaped extraction tube 4, a closing plate 5 for closing the outlets 3a, 3b of the extraction tube 4, and a closing plate 5 for each. And a pair of connected operating projections 6.

  In addition, the container main body 2 and the dispensing cylinder 4 described above are disposed in a state where the respective central axes are located on a common axis. In the present embodiment, this common axis is referred to as a container axis O, the dispensing cylinder 4 side along the container axis O is referred to as the upper side, and the container body 2 side is referred to as the lower side. A direction perpendicular to the container axis O is referred to as a radial direction, and a direction around the container axis O is referred to as a circumferential direction.

The dispensing cylinder 4 has a cylinder body 11 that is inserted into the injection port 101 and a top wall portion 12 that closes the upper end opening of the cylinder body 11.
The cylinder main body 11 has a diameter smaller than the inner diameter of the injection port 101 of the container 100 and extends upward from the opening edge of the mouth portion 2 a in the container main body 2. Further, as shown in FIG. 4, the cylindrical main body 11 of the present embodiment has a rectangular shape in which the cross-sectional view orthogonal to the container axis O includes a pair of short side portions 11 a and a pair of long side portions 11 b. There is no. In the illustrated example, the short side portion 11a is a curved surface protruding outward in the radial direction, and the long side portion 11b is a flat surface. The cylinder body 11 can be appropriately changed in design such as a cylindrical shape or a rectangular tube shape.

As shown in FIGS. 2 and 3, the cylinder main body 11 is attached to the mouth portion 2 a of the container main body 2 via an attachment cylinder 13 integrally formed at the lower end.
The mounting cylinder 13 protrudes radially outward from the lower end portion of the dispensing cylinder 4, and has an annular flange portion 14 disposed on the opening edge of the mouth portion 2 a, A base tube portion 15 extending downward from the periphery and screwed into the mouth portion 2a of the container main body 2 and the flange portion 14 are formed on the inner side in the radial direction of the base tube portion 15, And a sealing cylinder 16 fitted into the two mouth portions 2a. In the illustrated example, the base tube portion 15 is screwed into the mouth portion 2a of the container body 2. However, the present invention is not limited to this case, and the base tube portion 15 may be attached by undercut fitting or the like. In any case, it suffices that the mounting cylinder 13 is mounted on the mouth 2a of the container body 2.

The inner peripheral edge of the flange portion 14 is located on the inner side in the radial direction than the mouth portion 2a. The flange portion 14 is formed with a plurality of contact portions 21 projecting upward at intervals in the circumferential direction. In the illustrated example, a pair of contact portions 21 are formed so as to face each other in the radial direction at a position corresponding to each short side portion 11 a of the extraction tube 4 in the flange portion 14. Each contact portion 21 is formed over the entire radial direction from the inner peripheral edge to the outer peripheral edge of the flange portion 14, and the inner peripheral edge is connected to the lower end portion of the dispensing tube 4 (short side portion 11 a). Has been.
In the illustrated example, the contact portion 21 is formed in a thin rib shape in the circumferential direction. However, the present invention is not limited to this, and the contact portion 21 may be formed in a thick block shape in the circumferential direction or as a rising step portion. The design can be changed as appropriate. Further, a groove that opens upward may be formed in the flange portion 14, and a portion other than the groove in the flange portion 14 may function as the contact portion 21.

  The seal tube 16 is in close contact with the inner peripheral surface of the mouth portion 2a from the inside in the radial direction, and seals between the mouth portion 2a and the mounting tube 13 in a liquid-tight manner, for example.

  Here, as shown in FIG. 2 and FIG. 4, the spouts 3 a and 3 b of the present embodiment are formed at positions opposed to each other in the radial direction in the long side portions 11 b of the cylinder body 11, respectively, on the outside in the radial direction. Open toward. Specifically, each spout 3a, 3b is formed in a slit shape extending along the container axis O direction, its upper end is located at the boundary between the cylinder body 11 and the top wall 12, and the lower end is It is located at the lower edge of the cylinder body 11. Moreover, the upper end part of each spout 3a, 3b is formed so that the opening width along a circumferential direction may reduce gradually as it goes upwards (refer FIG. 2).

  Furthermore, as shown in FIG. 4, the opening widths Da and Db along the circumferential direction of the spouts 3a and 3b are different from each other. In the illustrated example, the opening width Da of the spout 3a is larger than the opening width Db of the spout 3b. In this case, each spout 3a, 3b is formed in the center part of the circumferential direction in the long side part 11b, and the spout 3a is expanded toward the both sides of the circumferential direction with respect to the spout 3b.

  As shown in FIGS. 2 and 4, the closing plate 5 is formed following the shape of the spouts 3 a and 3 b to block the spouts 3 a and 3 b separately. That is, the closing plate 5 is formed in a strip shape extending along the container axis O direction, and is formed such that the width along the circumferential direction gradually decreases as the upper end portion thereof moves upward. Of the closing plate 5, for example, side edges and upper edges located on both sides in the circumferential direction are connected to opening edges of the spouts 3a and 3b via a breakable weakening 22 (see FIG. 4). . In the illustrated example, the closing plate 5 is formed thin with respect to the cylinder main body 11.

  As shown in FIGS. 1, 2, and 5, each operation protrusion 6 opens the closing plate 5 when the dispensing cylinder 4 is moved inside the container 100 along the container axis O direction. And it is a member which opens spout 3a, 3b, Comprising: It is provided corresponding to each obstruction board 5 in the position which differs from the contact part 21 mentioned above in the circumferential direction. Specifically, each operation protrusion 6 is disposed on the radially outer side with respect to the dispensing cylinder 4 (long side portion 11b), and the protrusion main body 31 having one end 31a connected to the closing plate 5; A C-shaped hook portion 32 is provided at the other end portion 31b of the projecting piece body 31 and opens upward.

One end portion 31 a of the projecting piece main body 31 projects from the uppermost portion of the closing plate 5 toward the outside in the radial direction.
The other end 31b of the protruding piece main body 31 is disposed in a position facing the closing plate 5 in the radial direction, and has a strip shape extending along the container axis O direction. Specifically, the projecting piece body 31 gradually extends outward in the radial direction from the upper side to the lower side, and is elastically deformable in the radial direction.

  The hook portion 32 is connected to the other end portion 31b of the projecting piece body 31 and extends downward, an outer cylinder portion 36 surrounding the inner cylinder portion 35 from the outside in the radial direction, It has a contact part 37 that connects the lower ends of the inner cylinder part 35 and the outer cylinder part 36 and can contact the opening edge of the inlet 101 of the container 100. In the illustrated example, the width of the hook portion 32 along the circumferential direction is the same as that of the protruding piece body 31.

The inner cylinder part 35 is formed thick so that the inner diameter gradually decreases with respect to the other end part 31b of the protruding piece body 31 as it goes downward. Therefore, the operation protruding piece 6 (the protruding piece main body 31 and the hook portion 32) of the present embodiment has a bent shape that protrudes outward in the radial direction as a whole. Moreover, the lower end part of the inner cylinder part 35 is connected with the long side part 11b of the cylinder main body 11 through the bridge | bridging part 38 which can be broken.
The contact portion 37 is provided so as to protrude radially outward from the lower end of the inner cylinder portion 35, and the radially outer end portion is located on the radially outer side of the inlet 101 of the container 100. Is set to

  The outer cylinder part 36 protrudes upward from the radially outer end of the contact part 37. As shown in FIG. 5, the hook portion 32 has the inner cylindrical portion 35 and the outer cylindrical portion 36 in the injection port 101 in a state where the contact portion 37 is in contact with the opening edge of the injection port 101 of the container 100. Is arranged so as to be sandwiched from both sides in the radial direction so that it is engaged with the injection port 101.

Next, a method for refilling the contents from the refill container 1 to the main container 100 will be described.
As shown in FIGS. 5 and 6, the refill container 1 is first turned upside down, and the mouth 2 a of the refill container 1 and the inlet 101 of the main container 100 are opposed to each other with the main container 100 in the upright position. Let them be arranged. Here, by setting the refill container 1 in the inverted posture, 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 4 along the container axis O is the lower side, the container body The 2 side is the upper side.

  In this state, the refill container 1 and the main container 100 are aligned so that the container axes O are coaxial with each other, and the dispensing cylinder 4 and the operation protrusion 6 are inserted into the injection port 101 of the main container 100. . At this time, the refill container 1 and the main container 100 are brought close to each other along the container axis O direction until the contact portion 37 of the hook portion 32 contacts the opening edge of the injection port 101 in the main container 100. Thereby, the refill container 1 and the main container 100 are combined with the hook portion 32 of the refill container 1 engaged with the injection port 101 of the main container 100.

  The refill container 1 has the outlets 3a and 3b closed by the closing plate 5. Therefore, even if the refill container 1 is turned upside down, the content in the container body 2 flows out through the spouts 3a and 3b. Never do.

  Subsequently, with the hook part 32 engaged with the inlet 101 of the main container 100, the refill container 1 and the main container 100 are moved relatively close to each other in the direction of the container axis O, and the bridge part 38 is broken. Then, the dispensing cylinder 4 is moved downward so as to be pushed into the inside of the container 100. At this time, since the hook portion 32 is engaged, the projecting piece main body 31 is gradually stretched with the movement of the dispensing tube 4 to the inside of the container 100, and the projecting piece main body 31 is gradually pulled up. Accordingly, a tensile force can be applied to the closing plate 5 relatively.

  As a result, as shown in FIGS. 7 and 8, the blocking plate 5 can be deformed so as to gradually creep from the lower side to the upper side while breaking the weakened portion 22, and the spout closed by the blocking plate 5. 3a and 3b can be opened. And the content in the container main body 2 is poured out into this container 100 through the open | released spout 3a, 3b (refer arrow Q in FIG. 7), and can be refilled in this container 100. . In the illustrated example, the dispensing cylinder 4 is pushed into the inside of the container 100 until the contact portion 21 contacts the opening edge of the inlet 101 in the container 100.

As described above, in the present embodiment, the refill container 1 and the main container 100 are relatively moved along the container axis O direction while the hook portion 32 is engaged with the inlet 101 of the main container 100. The work of refilling the contents can be easily performed by a simple operation. In addition, since the outlets 3a and 3b are closed by the closing plate 5 until the container body 2 and the main container 100 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.
Furthermore, since the contents can be refilled into the main container 100 simultaneously with the opening of the refill container 1, the refilling operation can be performed without placing the main container 100 in an inverted posture. For example, the contents in the main container 100 remain. Even if it is, it is possible to refill the contents.

  Further, as shown in FIG. 2, the other end 31b of the projecting piece body 31 provided with the hook 32 is disposed below the one end 31a, so that the hook 32 is connected to the inlet of the container 100. When engaged with the opening edge of 101, the dispensing tube 4 can be inserted in advance into the inlet 101 of the container 100 as shown in FIG. 5. Therefore, at the stage before refilling, the refilling container 1 can be combined with the present container 100 in a more stable state, and the contents are more difficult to spill during refilling.

Further, since the hook portion 32 is connected to the dispensing cylinder 4 via the bridge portion 38, the position of the hook portion 32 is stabilized when the refilling operation is performed, and the hook portion 32 is connected to the inlet 101 of the container 100. It is possible to easily engage with the open end edge. Thereby, the refilling operation can be performed more simply.
In addition, it is possible to prevent the closing plate 5 from being rolled and unsealed due to rattling of the hook portion 32 before refilling.

Here, in this embodiment, since the spouts 3a and 3b are opened toward the outside in the radial direction during the refilling operation, the contents poured out from the spouts 3a and 3b are directed toward the inner wall of the container 100. And the contents can be prevented from foaming or splashing in the container 100.
Further, since the opening widths of the pair of outlets 3a and 3b are different from each other, the contents are positively extracted from the outlet 3a having the larger opening width Da among the outlets 3a and 3b. Therefore, of the spouts 3a and 3b, the spout 3b having a small opening width Db is likely to have a gap between the opening edge and the contents, and the inside of the main container 100 and the container body 2 are formed through this gap. Air replacement can be performed efficiently (see arrow P1 in FIG. 7). Therefore, the contents in the container body 2 can be smoothly poured out into the container 100, and the refilling operation can be performed efficiently.

Furthermore, since the spouts 3a and 3b extend along the container axis O direction, the direction in which the weakened portion 22 extends (the direction in which the closing plate 5 is rolled), the refill container 1 and the main container 100 at the time of refilling. And the direction in which the two are moved relatively close to each other. Therefore, when the refill container 1 and the main container 100 are combined and the refill container 1 and the main container 100 are moved relatively close to each other in the container axis O direction, a force is efficiently applied to the weakening portion 22. As a result, excellent opening operability can be provided.
Moreover, the closing plate 5 of the present embodiment is thinner than the cylinder main body 11, and the width along the circumferential direction is gradually reduced toward the upper side, so that the refill container 1 and the main container 100 are connected to the container shaft. When moved relatively close to the O direction, the container can be smoothly opened along the container axis O direction.
Further, since the operation projecting piece 6 of the present embodiment is formed into a bent shape projecting outward in the radial direction as a whole, the tensile force acting on the closing plate 5 via the projecting piece main body 31 is the projecting piece 31. It acts diagonally upward (toward the outer side in the radial direction as it goes upward) along the other end 31b. Therefore, it is possible to efficiently apply force to the weakened portion 22 and reliably provide excellent opening operability.

Further, as shown in FIG. 8, the dispensing cylinder 4 is pushed into the inside of the main container 100 to a position where the abutting portion 21 comes into contact with the opening edge of the injection port 101 in the main container 100. The posture of the refill container 1 can be further stabilized, and the contents can be made difficult to spill.
Further, during the refilling operation, air replacement between the inside and outside of the container 100 is performed through a gap between the portion other than the contact portion 21 in the flange portion 14 and the opening edge of the inlet 101 in the container 100. Can be efficiently performed (see arrow P2 in FIG. 8). Therefore, the contents can be smoothly poured out into the container 100 and the refilling operation can be performed efficiently.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.

For example, in the embodiment described above, the spouts 3a and 3b are formed in a slit shape extending in the container axis O direction, but the present invention is not limited to this, and the spouts 3a and 3b may be formed in a part of the tube main body 11.
Moreover, the design etc. of the magnitude | sizes, etc. of spout 3a, 3b can be changed suitably.
Moreover, in embodiment mentioned above, it was set as the structure which forms a pair of spout 3a, 3b in the position which opposes in the radial direction among the cylinder main bodies 11, However, Not only this but it forms in the arbitrary positions of the cylinder main body 11. Is possible.

  Furthermore, although the hook part 32 demonstrated as C shape which has the inner cylinder part 35, the outer cylinder part 36, and the contact part 37 in embodiment mentioned above, not only this but the inner cylinder part 35 and contact part It does not matter even if it is L-shaped consisting of 37. In this case, the hook portion 32 is engaged with the injection port 101 of the main container 100 when the contact portion 37 contacts the opening edge of the injection port 101 in the main container 100.

  In addition, in the range which does not deviate from the meaning of this invention, it is possible to replace suitably the component in the embodiment mentioned above by the known component, and you may combine the modification mentioned above suitably.
