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 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 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 container main body along the container axial direction. A pouring tube which 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 which closes the spout. An obstruction plate formed on the obstruction plate, and an operation protrusion connected to the obstruction plate. The obstruction plate has a front surface and a rear surface that are formed flat and extend along an orthogonal plane perpendicular to the container axis. Is arranged on the outer side in the radial direction of the dispensing cylinder, and opens toward the outer side of the container main body along the container axial direction and engages with the opening edge of the inlet of the main container, One end is connected to the closing plate and the other end is connected to the hook And the one end portion gradually extends toward the other end portion along the radial direction toward the outside of the container main body along the container axial direction, and the container axial direction. It curves so that the curved surface shape which protrudes toward the outer side of the said container main body along may be made | formed.

According to the present invention, since the hook portion is formed at the other end portion of the protruding piece main body disposed on the radially outer side of the dispensing cylinder, the hook portion is engaged with the opening edge of the inlet of the container. While being stopped, 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 projecting piece main body is gradually stretched with the movement of the dispensing tube to the inner side of the main container, and gradually, through the main projecting piece body. Thus, a tensile force can be applied to the closing plate.
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 with the unopened refilling container placed in an inverted posture without placing the container in an inverted posture, for example, even if the contents in the container remain, It can be carried out.

  The one end of the projecting piece body gradually extends toward the other end side along the radial direction as it goes toward the outside of the container body along the container axis direction, and the outside of the container body along the container axis direction Since it is curved so as to form a curved surface that protrudes toward the container, for example, this end portion extends straight toward the outside of the container body along the container axial direction. When the weakened portion is broken by applying a tensile force to the end portion, it is possible to prevent the one end portion from being caught by the tip end portion of the dispensing cylinder. As a result, when the container main body and the main container are moved close to each other in order to break the weakened portion, the force applied to the container main body and the main container can be kept small, and the operability of the refilling work is improved. be able to.

  Further, the entire protruding piece main body may be curved so as to form a curved surface that protrudes toward the outside of the container main body along the container axial direction.

  In this case, the entire protruding piece main body is curved so as to form a curved surface that protrudes toward the outside of the container main body along the container axial direction, so that the weakened portion is broken by applying a tensile force to the closing plate. In this case, it is possible to suppress the entire protruding piece main body from being caught by the tip of the dispensing cylinder, and the force applied to the container main body and the main container can be further reduced.

  Further, the one end portion may be located on the opposite side of the other end portion sandwiching the container shaft in the radial direction.

  In this case, one end of the projecting piece main body is located on the opposite side of the other end of the projecting piece main body with the container shaft radially interposed therebetween. Even if it is formed so as to straddle in the radial direction, the tensile force acting on the protruding piece main body can be efficiently transmitted from one end of the protruding piece main body to the weakened portion via the closing plate. As a result, when the container main body and the main container are moved close to each other in order to open the spout, it is possible to reduce the force applied to the container main body and the main container, and to the extraction tube of the projecting piece main body. Combined with the fact that the hooking is suppressed, it is possible to secure the operability of the refilling work after forming a large spout and improve the efficiency of the refilling work.

  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. .

  In addition, the container main body 2 and the extraction cylinder 3 described above are arranged 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 3 side along the container axis O is referred to as the upper side, and the container main 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 mouth 2a and the body 2b in the container body 2 are formed in a cylindrical shape.
The dispensing cylinder 3 is formed in a cylindrical shape extending upward from the mouth portion 2a of the container body 2 along the container axis O direction, and the container body is connected via a mounting cylinder 10 connected to the lower end. 2 is attached to the mouth portion 2a. An upper end opening of the dispensing cylinder 3 is a dispensing outlet 3a.
The dispensing cylinder 3 includes a curved wall portion 41 that is curved along the circumferential direction, and a flat wall portion 42 that connects both circumferential ends of the curved wall portion 41, and is orthogonal to the container axis O. The cross-sectional view shape is D-shaped.

The mounting cylinder 10 has a larger diameter than the pouring cylinder 3 and is screwed into the mouth 2a of the container body 2, and a lower end portion of the pouring cylinder 3 and an upper end portion of the peripheral wall section 11. And an annular flange portion 13 that is connected and disposed on the opening edge of the mouth portion 2a.
A plurality of bumps 15 are formed on the upper surface of the flange portion 13 at intervals in the circumferential direction. The bump 15 is formed in a plate shape whose front and back faces in the circumferential direction. The abutment projection 15 is connected to the outer peripheral surface of the lower end portion of the dispensing cylinder 3. In the illustrated example, the bumping protrusion 15 is connected to the outer peripheral surface of the lower end portion of the curved wall portion 41 of the dispensing tube 3.

  In addition, the flange part 13 is formed with a seal cylinder 14 that fits inside the mouth part 2a of the container body 2, and seals between the mouth part 2a and the mounting cylinder 10 in a liquid-tight manner, for example. Moreover, in the example of illustration, although the surrounding wall part 11 was screwed by the opening part 2a of the container main body 2, it is not limited to this case, For example, you may carry out undercut fitting.

  The outer diameter of the dispensing tube 3 is equal to or smaller than the inner diameter of the inlet 1A of the container A. The upper end opening surface of the dispensing cylinder 3 where the dispensing outlet 3 a is located extends along a horizontal direction orthogonal to the container axis O.

The closing plate 4 is formed following the shape of the spout 3a to close the spout 3a, and is connected to the peripheral edge of the opening of the spout 3a via a breakable weakening 30.
Here, in this embodiment, the top view shape of the opening periphery of the spout 3 a is the same D shape as the cross section view shape of the pour tube 3. The closing plate 4 is connected to only the curved portion in the top view through the weakening portion 30 in the peripheral edge of the spout 3a, and the connecting portion is not easily broken in the straight portion in the top view. 31 are connected. The thickness of the weakened portion 30 is smaller than the thickness of the closing plate 4, and the thickness of the connecting portion 31 is equal to the thickness of the closing plate 4. Moreover, the obstruction | occlusion board 4 is formed thinner than the thickness of the extraction | pouring cylinder 3, and can be deform | transformed (for example, elastic deformation is possible). The front and back surfaces of the closing plate 4 are flat surfaces orthogonal to the container axis O.
Note that the blocking plate 4 may be difficult to be deformed by setting the wall thickness to be equal to or greater than the wall thickness of the dispensing cylinder 3, for example.

The operation protrusion 5 includes a band-shaped protrusion main body 20 having one end 20 a connected to the closing plate 4 and the other end 20 b arranged on the radially outer side of the extraction tube 3. And a hook portion 21 that is connected to the end portion 20b and opens upward.
The central portion in the circumferential direction of the operation protrusion 5 coincides with the central portion in the circumferential direction of each of the curved wall portion 41 and the flat wall portion 42 in the dispensing cylinder 3.

  The protruding piece main body 20 extends from the one end 20a toward the other end 20b so as to form a straight line when viewed from above. The protruding piece main body 20 straddles the container axis O in the radial direction, and one end 20a of the protruding piece main body 20 is located on the opposite side of the other end 20b sandwiching the container axis O in the radial direction. The one end portion 20a extends upward from the closing plate 4 and is located above the other end portion 20b.

In the present embodiment, the one end portion 20a gradually extends toward the other end portion 20b along the radial direction as it goes upward, and toward the upper side that is the outside of the container body 2 along the container axis O direction. It is curved so as to form a curved surface. In the present embodiment, the entire protruding piece main body 20 is curved so as to form a curved surface that protrudes upward.
In a vertical sectional view of the refill container 1 passing through the one end 20a and the other end 20b of the projecting piece main body 20, the thickness of the projecting piece main body 20 is the most at the intermediate portion between the one end 20a and the other end 20b. It is small and is largest at the one end 20a. Further, the outer surface facing upward and the inner surface facing downward in the projecting piece main body 20 each have a curved shape that protrudes upward. Of the inner surface of the projecting piece main body 20, at least a portion located on the one end 20a side of the container axis O is formed in a single arc shape. In the illustrated example, both the outer surface and the inner surface of the projecting piece main body 20 are formed in a single arc shape, and are continuously curved over the entire length.

The hook portion 21 is disposed on the outer side in the radial direction of the dispensing cylinder 3, and the other end portion 20 b of the protruding piece main body 20 is connected to the hook portion 21 from the upper side. The hook part 21 is connected to the other end part 20b of the projecting piece body 20, and is connected to the inner part 21a protruding downward, the connecting part 21b extending radially outward from the lower end of the inner part 21a, and the connecting part 21b. And an outer portion 21c protruding upward from the outer end in the radial direction.
Here, in the present embodiment, the outer surface of the outer portion 21 c of the hook portion 21 that faces the outer side in the radial direction is located on the outermost side in the radial direction. The outer surface of the outer portion 21 c is located on the outer side in the radial direction with respect to the outer peripheral surface of the mounting cylinder 10 and on the inner side in the radial direction with respect to the outer peripheral surface of the body portion 2 b of the container body 2.
The hook portion 21 is open in both circumferential directions. The width along the circumferential direction of the hook portion 21 is equal to the width along the circumferential direction of the protruding piece main body 20. The inner portion 21 a of the hook portion 21 is connected to the outer peripheral surface of the dispensing tube 3 via a breakable bridge portion 22. In the illustrated example, the inner portion 21 a of the hook portion 21 is connected to the outer peripheral surface of the flat wall portion 42 of the dispensing tube 3.

The dispensing tube 3 is provided with a protective projection 16 projecting upward. The upper end portion (tip portion) 16c of the protective projection 16 is equivalent to the upper end portion (tip portion) of the operation projection piece 5 along the container axis O direction, or the upper end portion of the operation projection piece 5 It is located above.
The protective projection 16 is disposed in a portion of the dispensing cylinder 3 that is located on the opposite side of the other end 20b of the projecting piece body 20 that sandwiches one end 20a of the projecting piece body 20 in the radial direction. In the illustrated example, the protective projection 16 is disposed in the center portion in the circumferential direction of the upper end opening edge of the curved wall portion 41 in the dispensing tube 3. Note that one end portion 20 a of the projecting piece main body 20 is connected to a portion of the outer peripheral edge portion of the closing plate 4 adjacent to the inner side in the radial direction of the protective protrusion 16.
Further, the protective protrusion 16 is formed so as to be inserted into the injection port 1 </ b> A of the main container A together with the dispensing cylinder 3. The protective protrusion 16 does not protrude radially outward from the outer peripheral surface of the dispensing cylinder 3, and in the illustrated example, the outer surface 16a facing the radially outer side of the outer surface of the protective protrusion 16 is circumferential. And is substantially flush with the outer peripheral surface of the dispensing tube 3. The circumferential width of the protective protrusion 16 is larger than the circumferential width of the one end 20 a of the protruding piece body 20. The thickness of the thickest portion of the protective protrusion 16 is equal to the thickness of the dispensing tube 3.

  Here, of the outer surface of the protective protrusion 16, the inner side surface 16b facing the operation protrusion piece 5 is a flat surface, and the operation protrusion piece 5 is a top view when the refill container 1 is viewed from the container axis O direction. The dividing line L which bisects the line symmetrically and the inner side surface 16b of the protective projection 16 are orthogonal to each other. In the illustrated example, the dividing line L is orthogonal to the container axis O. Further, the dividing line L is orthogonal to the central portion of the inner side surface 16 b of the protective protrusion 16 in the top view. Furthermore, in the top view, the inner side surface 16b of the protective projection 16 and the flat wall portion 42 of the dispensing cylinder 3 are parallel to each other.

  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, the refill container 1 is placed on the other end 20b of the projecting piece body 20 after the refill container 1 is placed above the main container A in the upright position and the main container A in the upright position. 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 outer surface 16a of the protective protrusion 16 and the outer peripheral surface of the curved wall portion 41 of the dispensing tube 3 are close to or abutting the inner peripheral surface of the injection port 1A, and the protruding piece main body 20 is in the injection port 1A. The outer peripheral surface of the flat wall portion 42 of the dispensing cylinder 3 is opposed to the inner peripheral surface of the injection port 1A with the other end portion 20b of the protruding piece body 20 interposed therebetween. Further, the bumping protrusion 15 is located above the opening edge of the injection port 1 </ b> A, and a part of the flange portion 13 is located above the connecting portion 21 b of the hook portion 21.
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, as shown in FIG. 3, 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 section 21 is locked to the main container A, and the bridge section 22 is moved. The pour cylinder 3 is moved downward so as to be inserted into the inside of the container A while breaking. At this time, since the hook portion 21 is locked to the main container A, the projecting piece body 20 gradually becomes tensioned as the pouring cylinder 3 moves to the inner side of the main container A. A tensile force can be applied to the closing plate 4 via the piece body 20. At this time, the one end portion 20 a is deformed so that the inner surface of the one end portion 20 a approaches the surface of the closing plate 4 while the curvature of the curved shape formed by the one end portion 20 a of the protruding piece main body 20 increases.

  Therefore, as shown in FIG. 4, the blocking plate 4 can be deformed or displaced toward the opposite side of the protective projection 16 that sandwiches the container shaft O in the radial direction while the weakened portion 30 is broken, and is blocked. 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.

  In the state in which the dispensing cylinder 3 is completely inserted into the inlet 1A of the container A, as shown in FIG. 4, the abutting protrusion 15 comes into contact with the opening edge of the inlet 1A, A gap between the opening edge of the inlet 1A and the upper surface of the flange portion 13 of the mounting cylinder 10 is ensured, the connecting portion 21b of the hook portion 21 abuts on the flange portion 13 of the mounting cylinder 10, and The outer peripheral surface of the curved wall portion 41 of the extraction cylinder 3 is close to or abuts on the inner peripheral surface of the injection port 1A, and the projecting piece body 20 is connected to the outer peripheral surface of the flat wall portion 42 of the extraction tube 3 and Enter the gap between the inner peripheral surface. In this state, when the contents are poured out from the spout 3a into the main container A, the air in the main container A is, for example, the inner peripheral surface of the inlet 1A and the outer periphery of the flat wall portion 42 of the spout cylinder 3. Is discharged out of the container A through a gap between the surface and the opening edge of the inlet 1A and the upper surface of the flange portion 13 of the mounting cylinder 10, and the air replacement of the container A is performed smoothly. Is called.

As described above, according to the refill container 1 according to the present embodiment, the refill container 1 and the main container A are relatively moved along the container axis O direction while the hook portion 21 is locked to the main container A. The contents can be refilled by a simple operation of moving closer.
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 with the unopened refill container 1 placed in the inverted posture without placing the main container A in the inverted posture, for example, even if the content in the main container A remains, Refilling work can be performed.

  Then, the one end 20a of the projecting piece main body 20 is gradually curved toward the other end 20b side along the radial direction and curved so as to form a curved surface projecting upward toward the upper side. Therefore, for example, compared with a case where the one end portion 20a extends straight toward the upper side, when the weakening portion 30 is broken by applying a tensile force to the closing plate 4, the one end portion 20a is It is possible to suppress the catching tube 3 from being caught on the tip portion. As a result, when the container main body 2 and the main container A are moved close to each other in order to break the weakened portion 30, it is possible to suppress the force applied to the container main body 2 and the main container A, and refilling work can be performed. Operability can be improved.

Further, since the entire projecting piece main body 20 is curved so as to form a curved surface projecting upward, the projecting piece is used when the weakening portion 30 is broken by applying a tensile force to the closing plate 4. It becomes possible to suppress that the whole main body 20 is caught by the front-end | tip part of the extraction | pouring cylinder 3, and the force added to the container main body 2 and this container A can be suppressed further smaller.
Furthermore, since one end 20a of the projecting piece main body 20 is located on the opposite side of the other end 20b of the projecting piece main body 20 with the container shaft O sandwiched in the radial direction, the spout 3a is formed in a large size. Even when the plate 4 is formed so as to straddle the container axis O in the radial direction, the tensile force acting on the protruding piece main body 20 is weakened from the one end 20a of the protruding piece main body 20 through the closing plate 4. It is possible to efficiently transmit to the unit 30. As a result, when the container main body 2 and the main container A are moved closer to open the spout 3a, the force applied to the container main body 2 and the main container A can be kept small. Combined with the fact that 20 is prevented from being caught on the dispensing cylinder 3, it is possible to secure the operability of the refilling work and to improve the efficiency of the refilling work after forming the spout 3a large.

  Further, since the above-described protective protrusion 16 is disposed on the dispensing tube 3, for example, when the refill container 1 falls, the other member is not the operation protrusion piece 5, but the protective protrusion 16 first. It is possible to prevent an external force from being applied to the operation protrusion 5 unexpectedly, and to prevent the weakened portion 30 from being unintentionally broken and the spout 3a from being opened.

  Further, since the protective protrusion 16 can be inserted into the injection port 1A of the main container A together with the dispensing cylinder 3, the protective protrusion 16 is in sliding contact with the opening edge of the inlet 1A of the main container A. The pouring tube 3 of the refill container 1 can be inserted into the injection port 1A of the main container A together with the protective protrusion 16 and can be easily inserted.

  In addition, since the dividing line L that bisects the operation protrusion 5 in line symmetry and the inner side surface 16b of the protective protrusion 16 are orthogonal to each other when viewed from above, a pair of molding dies for molding the refill container 1 Can be made to coincide with the direction orthogonal to the dividing line L in the top view, and the refill container can be easily formed without complicating the molding die.

Moreover, since the outer surface of the outer side portion 21c located on the outermost side in the radial direction among the operation protrusions 5 is located on the inner side in the radial direction with respect to the outer peripheral surface of the body portion 2b of the container body 2, for example, When the refill container 1 falls, other members easily collide with the body 2b of the container body 2 instead of the operation projecting piece 5, and the external force is prevented from being applied to the operation projecting piece 5 unexpectedly. It becomes possible, and it can suppress that the weakening part 30 is fractured | ruptured unintentionally and the spout 3a is opened.
Further, since the outer portion 21 c of the operation protrusion 5 is positioned on the outer side in the radial direction from the outer peripheral surface of the mounting cylinder 10, other members can easily collide with the operation protrusion 5 as compared with the mounting cylinder 10. Nevertheless, since the other members can easily collide with the body portion 2b, the above-described effects are remarkably achieved.

  The present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.

For example, in the above-described embodiment, the configuration in which the inner side surface 16b of the protective protrusion 16 is formed as a flat surface is shown. However, the configuration is not limited thereto, and for example, it may be curved along the circumferential direction in the same manner as the outer side surface 16a. Further, for example, the protective protrusion 16 may cover the one end portion 20a of the protruding piece main body 20 from the outside in the radial direction over a certain range along the circumferential direction. For example, the thickness along the radial direction of the protective protrusion 16 may be equal to the thickness of the dispensing tube 3 over the entire circumference.
Further, a plurality of protective protrusions 16 may be disposed on the dispensing cylinder 3, and the inner side surface 16 b of the protective protrusion 16 may be formed in a curved shape protruding toward the operation protrusion piece 5. Further, the protective protrusion 16 may not be provided.

Moreover, in the said embodiment, although the extraction pipe | tube 3, the obstruction board 4, the operation protrusion 5, and the container main body 2 showed the structure made into a separate member, the container main body 2 is comprised with a tube container, for example. Depending on the circumstances, a configuration in which all are formed integrally may be adopted.
Moreover, in the said embodiment, although the hook part 21 and the outer peripheral surface of the extraction | pouring cylinder 3 were connected via the bridge | bridging part 22, it does not need to connect and the protrusion 15 may not be provided.
In addition, the dispensing cylinder 3 may have a cylindrical shape that does not have the flat wall portion 42 and has the curved wall portion 41 on the entire circumference.
Moreover, the mouth part 2a and the trunk | drum 2b in the container main body 2 are not restricted circularly, For example, you may change suitably rectangular shape or an ellipse shape.
Moreover, in the said embodiment, although the outer surface of the outer side part 21c of the hook part 21 was shown as a part located most radially outside among the operation protrusions 5, it is not restricted to this, For example, in the protrusion piece main body 20 You may change it.

  Moreover, in the said embodiment, although the obstruction board 4 is located on the container axis | shaft O and the front and back of the obstruction board 4 are orthogonal to the container axis | shaft O, this invention is not limited to this. For example, the closing plate 4 may be disposed at a position avoiding the container axis O. In the present invention, the front and back surfaces of the closing plate 4 are formed flat and extend along an orthogonal plane orthogonal to the container axis O. It can change suitably to other forms.

  Moreover, in the said embodiment, although the one end part 20a of the protruding piece main body 20 is located in the other side of the other end part 20b of the protruding piece main body 20 which pinched | interposed the container axis | shaft O to the radial direction, this invention is limited to this. I can't. For example, one end 20a of the projecting piece body 20 may be disposed on the container axis O, or may be disposed at a position sandwiched between the other end 20b and the container axis O in the radial direction.

  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.

  Next, a verification test for the above-described effects will be described.

  As an example, a refill container 1 shown in FIG. 1 was adopted, and as a comparative example, a refill container 50 shown in FIG. 5 was adopted. The refill container 50 is different from the refill container 1 shown in FIG.

  As shown in FIG. 5, in the refill container 50, one end portion 20 a of the protruding piece body 20 extends straight from the closing plate 4 along the container axis O direction. An intermediate portion of the projecting piece main body 20 is connected to the one end portion 20 a via a bent portion 51. The intermediate portion extends straight from the bent portion 51 toward the other end portion 20b along the radial direction, and the bent portion 51 has a right-angled shape.

  And in this verification test, when performing the refilling method of the content shown in the said embodiment about the refill container 1 of an Example and the refill container 50 of a comparative example, the weakening part 30 was fractured | ruptured and the whole spout 3a was The force (hereinafter referred to as “unplugging force”) required to move the refill containers 1 and 40 and the main container A closer to each other was measured until it was opened.

  At this time, in the refill container 1 of the example, as shown in FIGS. 3 and 4, the one end 20 a of the projecting piece main body 20 was suppressed from being caught by the tip of the dispensing cylinder 3. On the other hand, in the refill container 50 of the comparative example, as shown in FIGS. 6 and 7, the one end 20 a of the projecting piece main body 20 falls down to the other end 20 b side along the radial direction and In order to release this catch, a large plugging force was required.

  In this verification test, the refill container 1 of the example and the refill container 50 of the comparative example are each prepared in three, and the refill container 1 of the example and the refill container 50 of the comparative example have three plugging forces. The average value of the plugging power of the refill containers 1 and 50 was determined.

  As a result, in the refill container 1 of the example, the unplugging force is 17.2N, while in the refill container 50 of the comparative example, the unplugging force is 41.7N, and in the refill container 1 of the example, the refill container of the comparative example It was confirmed that it can be opened with a smaller opening force than 50.
