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, the contents are hardly spilled during refilling, and the contents in the container remain. Even if it is a case, it is providing the refill container which can perform the refilling operation | work.

  As a means for solving the above-mentioned problems, the present invention includes a container main body in which contents to be refilled in the container are accommodated, the container main body extending from the container main body toward the outside of the container main body along the axial direction of the container, and the book A pouring cylinder capable of being inserted into an inlet of the container; and an operation protrusion projecting outwardly in the radial direction on the pouring cylinder, and a radially outer end of the operation protrusion A hook portion that engages with an opening edge of the inlet of the main container is formed in the portion, and is adjacent to the connecting portion with the operation projecting piece from both sides in the circumferential direction of the dispensing cylinder. Each portion is formed with a breakable weakened portion, and the weakened portion extends from a connecting portion with the operation projecting piece in the dispensing tube toward the inside of the container main body along the container axial direction. It is characterized by.

  According to the refill container according to the present invention, the hooking portion disposed on the radially outer side of the pouring tube is engaged with the opening edge of the pouring port of the container, and the pouring tube is made to the pouring port of the container. Can be placed 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 tensile force toward the outside of the container, that is, the container main body in the refill container is applied to the operation projection piece with the movement of the dispensing cylinder to the inside of the container. A tensile force directed inward can be applied. Therefore, while the weakened portion is broken by the tensile force applied to the operation projection piece along with the movement of the dispensing cylinder to the inside of the container, the inside of the dispensing cylinder is opened to the outside in the radial direction. The contents in the container body can be poured into the container through the container, and the container can be refilled.

Thus, in the refill container according to the present invention, in particular, 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 engaging the hook portion. Since work can be performed, refilling work becomes easy.
In addition, the inside of the dispensing cylinder is not opened until the container body and the main container are moved relatively close to each other along the container axial direction. There is no spill. In addition, since the contents are refilled into the container at the same time as the refill container is opened, it is possible to perform refilling work without placing the container in an inverted position, and the contents in the container remain. Even if it exists, the refilling work of the contents can be performed.
Furthermore, the contents can be easily poured toward the inner wall of the container by opening the inside of the dispensing cylinder to the outside in the radial direction, and the contents can be bubbled or splashed in the container body. Can be suppressed.
In addition, since the direction in which the weakened portion extends and the direction in which the refill container and the main container are moved relatively closer to each other at the time of refilling are coincident with each other, 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 container axial direction, force is efficiently applied to the weakened portion, and excellent opening operability can be provided.

In the refill container, the hook portion forms an opening that opens toward the outside of the container body along the container axial direction, and the opening engages with the opening edge of the injection port. It is preferable to configure so as to.
In this case, the engagement between the hook portion and the opening edge of the inlet is more reliably achieved.

  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. .

It is a longitudinal cross-sectional view of the refill container which concerns on embodiment of this invention. It is a figure explaining the refilling operation | work of the said refill container, and is the figure which showed the state before opening of a refill container. It is a figure explaining the refilling operation | work of the said refill container, and is the figure which showed the state after opening of a refill container.

  Hereinafter, embodiments of a refill container according to the present invention will be described with reference to the drawings.

  A refill container 1 according to the present embodiment shown in FIG. 1 includes a bottomed cylindrical container body 2 in which contents (not shown) to be refilled in the main container A (see FIGS. 2 and 3) are accommodated, and a note of the main container A. A pouring tube 3 that can be inserted into the inlet A1 and an operation protrusion 4 that protrudes from the pouring tube 3 are provided.

  The container main body 2 and the dispensing cylinder 3 are disposed in a state where their respective central axes are positioned on a common axis. In the present embodiment, this common axis is referred to as a container axis O. The side of the extraction tube 3 along the side is referred to as the upper side, and the side of the container body 2 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 3 is formed in a cylindrical shape extending upward from the upper end opening 2a of the container body 2 along the container axis O direction. The dispensing cylinder 3 is formed integrally with the container body 2, and includes a cylinder body 3 </ b> A extending substantially straight upward from the upper end opening 2 a of the container body 2 along the container axis O direction, and an upper end opening of the cylinder body 3 </ b> A. And a sealing portion 3B to be closed.

  In this embodiment, the container main body 2 and the extraction cylinder 3 are integrally formed by blow molding, and the seal portion 3B of this embodiment is closed by thermally welding the upper end of the extraction cylinder 3 immediately after blow molding in the radial direction. It is formed by doing. For this reason, a part of the seal portion 3B protrudes outward in the radial direction with respect to the cylinder main body 3A.

  The dispensing cylinder 3 has a smaller diameter than the inner diameter of the inlet A1 of the container A, including the cylinder main body 3A and the seal portion 3B. In the present embodiment, the upper end portion of the dispensing tube 3 is closed by the seal portion 3B formed by heat welding, but may be configured to be closed by attaching a cap or the like.

The operation protrusion 4 is a member formed to open the inside of the dispensing cylinder 3 to the outside when the dispensing cylinder 3 is moved inside the container A along the container axis O direction. , One end 4a is connected to the pouring cylinder 3, and the other end 4b is arranged on the radially outer side of the pouring cylinder 3, and the diameter from the lower end side surface of the other end 4b of the projecting piece main body 20 And a hook portion 21 formed so as to protrude in a substantially L shape in the direction. The hook portion 21 in the present embodiment forms an opening portion that opens upward between the lower end portion of the other end portion 4b. That is, the hook portion 21 forms an opening portion that opens upward in cooperation with the other end portion 4b. The operation projecting piece 4 is formed in a flat plate shape, and a rib 8 extending continuously over the outer peripheral edge portion is formed. The rib 8 ensures rigidity. One end 4a of the projecting piece main body 20 protrudes radially outward from the outer peripheral surface of the dispensing tube 3, and the other end 4b of the projecting piece main body 20 extends downward from the radially outer end of the one end 4a. Protrusively toward.
As will be described later, the other end portion 4b of the projecting piece body 20 is poured out when the hook portion 21 (opening portion) is engaged (engaged so as to be sandwiched) with the opening edge of the inlet A1 of the container A. The tube 3 extends downward so that a portion to which the one end 4a is connected is located inside the injection port A1.

A concave portion 5 constricted radially inward is formed at the upper end portion of the cylinder main body 3A in the dispensing tube 3, and the concave portion 5 has a longitudinal section and is recessed at a substantially acute angle toward the radial inner side.
Of the recess 5, a portion 5b (hereinafter referred to as an upper portion 5b) extending upward from the inner end portion 5a in the radial direction and continuing to the lower end portion of the seal portion 3B has a protruding arc shape in a vertical sectional view. Moreover, the part 5c (henceforth the lower part 5c) extended below from the inner edge part 5a among the recessed parts 5 is exhibiting linear form by the longitudinal cross-sectional view.

  And the one end part 4a of the protrusion piece main body 20 in the operation protrusion 4 is connected over the inner end part 5a of the radial direction in the recessed part 5 in the extraction | pouring pipe | tube 3, and the above-mentioned lower site | part 5c. That is, the connection part with the operation protrusion 4 in the extraction | pouring cylinder 3 is the inner end part 5a of the radial direction in the recessed part 5, and the above-mentioned lower part 5c.

  Moreover, the hook part 21 is formed in the size with the width | variety along the circumferential direction substantially the same as the protrusion piece main body 20, for example.

And in this embodiment, the weakening part 7 which can be fracture | ruptured is formed in each part which adjoins from the both sides of the circumferential direction with respect to the connection part with the operation protrusion 4 among the extraction pipe | tubes 3. FIG.
These weakening parts 7 are extended toward the inner side of the container main body 2 along the container axis O direction from the said connection part. In the example shown in the drawing, the weakening portion 7 extends to the vicinity of the connection portion between the dispensing cylinder 3 and the container body 2, but such a length may be different from this example.
Moreover, although the weakening part 7 is continuously extended along the container axis | shaft O direction, you may change suitably, such as making it disperse | distribute intermittently or extend.

  Hereinafter, a method for refilling the contents from the refill container 1 into the main container A will be described with reference to FIGS.

  First, as shown in FIG. 2, after the refill container 1 is placed above the main container A in a state where the refill container 1 is in the inverted position and the main container A is in the upright position, the projecting piece main body 20 is disposed. The refill container 1 and the main container A are combined face-to-face while the hook portion 21 provided on the container is engaged with the opening edge of the inlet A1 of the main container A.

  In addition, by setting the refill container 1 in the inverted posture as described above, the top and bottom of the refill container 1 are inverted, and in the refill container 1 in the inverted posture, the side of the dispensing cylinder 3 along the container axis O direction is the lower side. The container body 2 side is the upper side. Further, in the refill container 1, when the hook portion 21 is engaged with the opening edge of the injection port A1 of the main container A, the pouring piece body 3 and the protruding piece main body 20 of the operation protruding piece 4 are both injected into the injection port A1. The dimension is set so as to be accommodated in the radially inner 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 portion 21 is engaged, and the weakened portion 7 is broken. The pouring cylinder 3 is moved downward so as to be inserted into the inside of the container A.

At this time, since the hook portion 21 is engaged with the opening edge of the inlet A1, the operation protrusion 4 is moved to the outer side of the container A ( A tensile force toward the upper side), that is, a tensile force toward the inside of the container body 2 of the refill container 1 can be applied. Therefore, the inside of the extraction cylinder 3 is opened to the outside in the radial direction while the weakened portion 7 is broken by the tensile force applied to the operation protrusion 4 as the extraction cylinder 3 moves to the inside of the container A. 3, the contents in the container body 2 can be poured out into the container A through the fractured part β, and the container A can be refilled. It will be possible.
In addition, although the connection part which the one end part 4a of the protrusion piece main body 20 in the extraction | pouring pipe | tube 3 connects becomes a fracture | rupture start location of the fracture | rupture part (beta), the hook part 21 is this container A in the other end part 4b of the protrusion piece main body 20. Since the connecting portion to which the one end 4a is connected extends downward so as to be located inside the injection port A1 when engaged with the opening edge of the injection port A1, the fracture portion immediately after the start of the fracture The content liquid is surely poured into the container A from β. In the refill container 1 of the present embodiment, as shown in FIG. 3, even when the weakened portion 7 breaks, the broken portion β formed by the breakage is entirely accommodated in the injection port A1. It becomes a state.

  Thus, in the refill container 1 according to the present embodiment, in particular, a simple operation of relatively moving the refill container 1 and the main container A along the container axis O direction while engaging the hook portion 21. Since the contents can be refilled, the refilling work is facilitated.

Further, since the inside of the dispensing tube 3 is not opened until the container body 2 and the main container A are relatively moved along the container axis O direction, the container body 2 is in a stage before refilling. The contents inside are not spilled.
Moreover, since the contents are refilled into the main container A at the same time as the refill container 1 is opened, the refilling operation can be performed without placing the main container A in an inverted position, and the contents in the main container A remain. Even if it is, it can refill the contents.

  Further, the contents are easily poured out toward the inner wall of the container A as shown by the arrow α in FIG. 3 by opening the inside of the dispensing cylinder 3 outward in the radial direction. It can suppress that an object foams or jumps in the container main body 2.

  In addition, since the direction in which the weakening portion 7 extends and the direction in which the refill container 1 and the main container A are relatively moved at the time of refilling coincide with each other, as described above, the refill container 1 and the book In a state where the container A is combined, when the refill container 1 and the main container A are moved relatively close to each other in the direction of the container axis O, a force is efficiently applied to the weakened portion 7, which is excellent. Opening operability can be provided.

  Furthermore, in this embodiment, the upper part 5b that continues from the upper part with respect to the connection part with the operation protrusion 4 in the dispensing cylinder 3 extends toward the inner side in the radial direction from the upper part to the lower part. Therefore, as compared with the case where the connecting portion of the dispensing tube 3 with the operation protrusion 4 extends along the container axis O direction, the dispensing tube 3 moves inward of the container A. Thus, the stress generated by the tensile force acting on the operation protrusion 4 is easily concentrated on the connecting portion. Therefore, the weakened part 7 becomes easy to fracture | rupture.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

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

  Moreover, in the said embodiment, although demonstrated that the container main body 2 and the extraction pipe | tube 3 were integrally formed by blow molding, you may form by another method.

  Moreover, although the seal part 3B in the extraction cylinder 3 is partly projected outward in the radial direction with respect to the lower cylinder body 3A, it is needless to say that the shape may not be such.

Moreover, in the said embodiment, although the one operation protrusion piece 4 was connected with respect to the extraction | pouring cylinder 3, you may provide multiple operation protrusion pieces 4. FIG. In this case, it is preferable to form the operation protrusions 4 so as to face each other with the container axis O interposed therebetween or at equal intervals.
Moreover, in the said embodiment, although the hook part 21 was formed in the substantially L shape, it is not limited to this shape. For example, the hook portion may be a flange-like member that is only a portion extending radially outward from the other end portion 4b. In this case, when the hook portion engages with the opening edge of the inlet A1, movement toward the radially inner side is difficult to be regulated, but manufacturing is facilitated. The hook portion may be arcuate.
