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 main body for storing contents to be refilled in the present container, a mouth mounted on the mouth of the container main body and the mouth There is known a refill container that includes an inner stopper that is closed, and that is refilled by screwing the inner stopper into the mouth of the container.
The above-described 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 having the above-described configuration, for example, the pull top is first pulled up to open the spout of the inner plug. Subsequently, the refill container is placed in an upright posture (the mouth portion is in an upward posture), and the mouth portion of the main container in an inverted posture (the mouth portion is in a downward posture) is screwed onto the inner plug of the refill container. Thereafter, the refill container and the main container are reversed 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.

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 turn the refill container and the main container upside down. Work was easy to become complicated.
Also, since the mouth of the container is screwed into the refill container after opening the spout of the inner plug, 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.
Further, since the container is placed in an inverted position when the mouth of the container is screwed onto the inner plug, the contents in the container are likely to spill if the contents remain inside 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.
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 an opening edge of the injection port portion of the main container that is attached to the mouth of the main container body and has a spout. A mounting cylinder provided with an abutting portion that is positioned radially outward from the spout and a seal wall that closes the spout, the seal wall having an outer peripheral edge portion A plurality of slit-shaped cut portions that are connected to the inner peripheral surface of the spout and extend in the radial direction about a radial axis orthogonal to the seal wall are formed from the outer peripheral edge portion to the radial axis. The seal wall gradually inclines toward the inside of the container main body along the radial axis direction as it goes, and the seal wall can be deformed so as to oscillate with the outer peripheral edge as a fulcrum. Along the outside of the container body Clearance of the cut portion is characterized in that it is closed when the.

According to the refill container of the present invention, when the contents are refilled in the container, first, the refill container is in an inverted posture with respect to the container, and the contact portion of the mounting cylinder is the open end of the inlet of the container. The refill container and the main container are combined in contact with the edge. At this time, the seal wall is pressed downward by the weight of the contents in the container body, and is deformed toward the outside of the container body along the radial axis direction with the outer peripheral edge as a fulcrum. Since the divided parts of the seal walls which are divided and are adjacent to each other are in close contact with each other and the cut portion can be closed to close the spout, the contents are less likely to leak from the seal wall.
Then, by compressing the container body of the refill container and forcibly pressing the seal wall with the contents, the seal wall is further deformed toward the outside of the container body along the radial axis direction, and the gap of the cut portion is widened. Thus, a flow path is secured at the spout.
Thereby, the inside of the container body of the refill container and the inside of the inlet of the main container communicate with each other, and the contents in the container main body are poured out into the inlet and refilled into the main container.

  As described above, the contents can be refilled by a simple operation of compressing the container body after combining the refill container and the main container in a state where the contact portion is in contact with the opening edge of the inlet portion. Therefore, refilling work can be facilitated.

Further, at the time of refilling, the contact portion located outside the spout is brought into contact with the opening edge of the injection port portion, so that the contents are hardly spilled.
Furthermore, when refilling the contents of this container, even if the refill container is placed in an inverted position with respect to the present container, the contents are difficult to leak from the sealing wall, so the refilling operation is performed without placing the container in an inverted position. Even if the contents in the container remain, the contents can be refilled.

  Moreover, the refill container of the said invention WHEREIN: It is preferable that the said container main body consists of a member which can carry out a squeeze deformation.

  In this case, when compressing the container body, the sealing wall can be pressed by the contents without requiring an excessive force, and the contents can be refilled easily.

  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 a refill container according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, the refill container 1 of the present embodiment includes a container main body 2 in which contents M (see FIG. 3) to be refilled in the main container 20 (see FIG. 3) and a mouth portion of the container main body 2. A mounting cylinder 4 provided with a contact portion (corresponding to a convex portion 13 to be described later) which is attached to 2a and has a spout 3 formed therein and capable of contacting the opening edge of the inlet portion 21 of the container 20; A removable cap 5 that covers the upper end opening of the mounting cylinder 4 and a seal wall 6 that closes the spout 3 are provided.

  In addition, the container main body 2, the mounting cylinder 4, and the cap 5 described above are disposed in a state in which 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, and in the refill container 1, the cap 5 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 mounting cylinder 4 includes an inner cylinder part 10 having a lower end fitted into the mouth part 2 a of the container body 2, an outer cylinder part 11 fitted to the mouth part 2 a of the container body 2, and an inner cylinder part 10. And a connecting ring 12 mounted on the opening edge of the mouth portion 2a while connecting the intermediate portion in the container axis O direction and the upper end portion of the outer cylinder portion 11. The inner surface of the inner cylinder portion 10 is the spout 3.

An annular groove 12b that opens toward the outside in the radial direction is formed on the outer peripheral edge of the connecting ring 12.
A plurality of convex portions 13 (contact portions) are provided on the upper surface 12a of the connecting ring 12 at intervals in the circumferential direction. These convex portions 13 are L-shaped in cross section and are formed from the upper surface 12 a of the connecting ring 12 to the outer peripheral surface 10 a of the inner cylinder portion 10.

The cap 5 is formed in a cylindrical shape with a top, and a seal cylinder 14 that is fitted into the inner cylinder 10 is projected from the top wall 15 and the lower end edge 16a of the peripheral wall 16 is locked to the annular groove 12b. Arranged to be possible.
A projecting portion 16 b that protrudes radially outward is formed on the lower end portion 16 a of the peripheral wall portion 16. In the peripheral wall 16, the portion located on the opposite side of the protrusion 16 b that sandwiches the container axis O in the radial direction is the hinge 17 at the upper end of the outer cylinder 11 of the mounting cylinder 4 (the outer peripheral edge of the connecting ring 12). Are connected through.
That is, the cap 5 is rotatable about the hinge portion 17, thereby opening and closing the upper end opening of the mounting cylinder 4 (see FIGS. 1 and 3).

As shown in FIGS. 1 and 2, the seal wall 6 has a radial axis extending in parallel with the container axis O while the outer peripheral edge 6 a is connected to an intermediate part in the container axis O direction on the inner peripheral surface of the spout 3. A plurality of slit-like cut portions 6b extending in the radial direction (radial direction in plan view) with C as the center are formed, and gradually incline downward toward the radial axis C from the outer peripheral edge portion 6a. These notches 6b extend from the radial axis C to the outer peripheral edge 6a of the seal wall 6.
Here, the radial axis C is an axis orthogonal to the seal wall 6 (specifically, a plane formed by the outer peripheral edge 6a of the seal wall 6). In the present embodiment, the radial axis C coincides with the container axis O.

  As shown in FIGS. 3 and 4, each of the divided portions of the seal wall 6 divided in the circumferential direction by the cut portions 6b swings around the outer peripheral edge 6a as a fulcrum. Thus, the gap between the cut portions 6b is closed at a position where the seal wall 6 becomes substantially planar along the radial direction. It has a configuration.

  Next, a method for refilling the contents from the refill container 1 configured as described above into the main container 20 will be described.

First, as shown in FIG. 3, after the cap 5 of the refill container 1 is removed from the mounting cylinder 4, the refill container 1 is placed in the upright position and the refill container 1 is placed in the upright position. It is arranged above the container 20. Then, the refill container 1 and the main container 20 are relatively moved closer to each other in the direction of the container axis O while aligning them, so that the upper surface 12a (convex portion 13) of the connecting ring 12 is placed on the main container 20 as shown in FIG. The refill container 1 and the main container 20 are combined in contact with the opening edge of the inlet portion 21.
At this time, a part of the upper end of the inner cylinder part 10 of the mounting cylinder 4 of the refill container 1 is inserted into the inlet part 21 of the main container 20 and disposed in the inlet part 21.

  Here, in this embodiment, the refill container 1 is turned upside down as described above, so that the top and bottom of the refill container 1 are inverted, and the cap 5 along the container axis O direction in the refill container 1 in the inverted position. The side is the lower side, and the container body 2 side is the upper side.

  Then, as shown in FIGS. 3 and 4, when the connecting ring 12 of the mounting cylinder 4 is brought into contact with the opening edge of the inlet 21 of the main container 20 and the refill container 1 and the main container 20 are combined, The seal wall 6 is pressed downward by the weight of the contents M in the container body 2, and deforms toward the outside of the container body 2 along the radial axis C with the outer peripheral edge 6a as a fulcrum. Since the divided parts of the seal walls 6 that are divided by the notch 6b and are adjacent to each other are in close contact with each other, the notch 6b can be closed and the spout 3 can be closed, so that the contents M hardly leak from the seal wall 6. Become.

Then, as shown in FIG. 5, the container body 2 of the refill container 1 is compressed and the seal wall 6 is forcibly pressed by the contents M, so that the seal wall 6 further extends along the radial axis C direction. The gap R of the cut portion 6b is widened to secure the flow path R in the spout 3.
Thereby, the inside of the container main body 2 of the refill container 1 and the inside of the inlet part 21 of the main container 20 communicate with each other, and the contents M in the container main body 2 can be poured into the inlet part 21 (FIG. 5). Arrow E), the contents M can be refilled from the refill container 1 into the main container 20.

  Note that the connecting ring 12 of the mounting cylinder 4 (in this embodiment, a plurality of projections 13 provided on the connecting ring 12) is in contact with the opening edge of the inlet 21 of the container 20, and the upper surface of the connecting ring 12. A gap is provided between 12a and the opening edge of the inlet port 21, and the inside and outside of the container 20 can be communicated with each other through this gap. Therefore, the air in the main container 20 can be replaced through the gap (arrow F shown in FIG. 5), and the contents M can be smoothly poured into the main container 20 to perform the refilling work efficiently.

  As described above, according to the refill container 1 of the present embodiment, the refill container 1 and the main container 20 with the connecting ring 12 of the mounting cylinder 4 in contact with the opening edge of the inlet 21 of the main container 20. Since the contents M can be refilled by a simple operation of crushing and compressing the container main body 2 after combining, the refilling operation can be facilitated.

Moreover, since the convex part 13 located outside the spout 3 is brought into contact with the opening edge of the inlet part 21 during the refilling, the contents M are hardly spilled.
Further, when refilling the contents M into the main container 20, even if the refill container 1 is placed in an inverted position with respect to the main container 20, it is difficult for the contents M to leak from the seal wall 6. It is possible to perform the refilling operation without taking the posture, and the content M can be refilled even when the content M in the container 20 remains.

  Furthermore, by adopting a squeeze-deformable member for the container body 2, when the container body 2 is compressed, the seal wall 6 can be pressed by the contents M without requiring excessive force. It becomes possible to easily refill the object M.

  Further, in the refill container 1 of the present embodiment, the mounting cylinder 4 can be mounted on the container body 2 after the contents M are filled, or the contents M can be filled after the mounting cylinder 4 is mounted on the container body 2. It is. In the latter case, it is possible to fill the contents M in a state where the filling nozzle is inserted into the spout 3 and the seal wall 6 is deformed inside the container body 2 along the radial axis C direction. Further, using the same means, it is possible to restore air by blowing air into the container body whose volume has been reduced in the manufacturing process.

  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, in this embodiment, the radial axis C of the seal wall 6 is the central axis of the circular seal wall 6 in plan view and coincides with the container axis O. However, the radial axis C and the container axis O do not necessarily coincide. There is no need, and the radial axis C may be different from the container axis O.

Further, in the refillable container 1 in the inverted posture, the close force of the cut portion 6b of the seal wall 6 is such that the divided bodies of the seal wall 6 are brought into close contact with each other by the weight of the contents M in the container body 2, and the gap between the cut portions 6b It is preferable to set the gap size and the inclination angle of the cut portion 6b to such an extent that the gap is filled.
Further, the number of the cut portions 6b of the seal wall 6 installed, that is, the number of divisions of the seal wall 6 can be arbitrarily set, but the content M sufficiently presses the seal wall 6 by compressing the container body 2. It is preferable to set the number of divisions to such an extent that it can be deformed.

Moreover, in the said embodiment, although the seal wall 6 was set as the structure provided in an intermediate part in the container axis O direction of the inner cylinder part 10 of the mounting cylinder 4, if the spout 3 can be obstruct | occluded, the position of the seal wall 6 will be It is not limited and can be set at an arbitrary position such as a lower end or an upper end of the inner cylinder portion 10.
Furthermore, in the said embodiment, although it has set as the structure compressed so that the container main body 2 may be crushed in the container axis | shaft O direction, for example, the structure which compresses a container main body to radial direction in the state which hold | gripped the trunk | drum of the container main body with one hand. Even in this case, the seal wall can be pressed with a large force by the contents with a simple operation, and the contents can be refilled easily.
