  The top wall 70 is disposed perpendicular to the central axis (the axis O in FIGS. 2 and 3) of the mouth 60 of the container body 6 and is disposed above the mouth 60 of the container body 6. ing. The outer cylinder portion 71 is a cylindrical tube portion provided around the outer periphery of the mouth portion 60 of the container body 6, and is undercut fitted to the mouth portion 60. The inner cylindrical portion 72 is a bottomed cylindrical portion that is gradually reduced in diameter as it goes downward, and is disposed inside the mouth portion 60 of the container body 6, and the upper end portion is the inner periphery of the lower end portion of the mounting cylindrical portion 75. It is integrally connected to the surface. The bottom portion 73 of the inner cylindrical portion 72 is a substantially annular wall portion in plan view with an opening formed at the center, and from one radial side (left side in FIG. 2) to the other radial side (right side in FIG. 2). Inclined downwards towards A recovery port 76 for recovering the contents in the inner cylinder portion 72 into the container body 6 is formed at the lowest portion of the bottom portion 73. The mounting cylinder part 75 is a cylinder part for mounting an overcap (not shown), and a male screw 77 for screwing the overcap (not shown) is formed on the outer peripheral surface of the mounting cylinder part 75. Further, the inner diameter of the mounting cylinder portion 75 is larger than the outer diameter of the mouth portion 20 of the container body 2 of the refill container 1, and the mouth portion 20 of the container body 2 of the refill container 1 can be inserted inside the mounting cylinder portion 75. is there.

  The nozzle 74 is a cylindrical tube portion for pouring the contents in the container body 6 described above, and is erected along the axial direction from the inner edge of the bottom portion 73 of the inner tube portion 72. The tip end of the nozzle 74 protrudes upward from the upper end of the mounting cylinder portion 75, and faces downward from one radial side (left side in FIG. 2) toward the other radial side (right side in FIG. 2). It is inclined. The nozzle 74 is formed with a slit 78 extending along the axial direction over the entire length. The slit 78 extends from the lowest position of the tip of the nozzle 74 to the recovery port 76 described above.

  Inside the nozzle 74 described above, a blade 8 for opening the seal portion 34 described above is disposed. As a schematic configuration of the blade 8, a bridge portion 80 installed inside the nozzle 74, and a plurality of (two in FIG. 3) projecting portions 81 and 82 erected from the upper surface of the bridge portion 80 are provided. ing. The bridge portion 80 is a plate-like portion extending in a direction orthogonal to the axis O, and both ends are integrally connected to the inner peripheral surface of the nozzle 74. The protrusions 81 and 82 are cylindrical portions whose upper ends are formed in a pointed shape. As shown in FIG. 3, the plurality of projecting portions 81 and 82 have different heights, and are arranged in parallel in the height direction along the extending direction of the bridge portion 80.

  Next, the operation of the refill container 1 having the above-described configuration will be described.

  When the contents stored in the container body 2 of the refill container 1 are refilled into the main container 5, first, as shown in FIG. 2, the overcap (not shown) of the main container 5 is removed and then refilled. In a state where the container 1 is in an inverted posture, the insertion tube portion 31 of the inner plug 3 of the refill container 1 is poured out from the refill container 1 so that the mouth portions 20 and 60 of the refill container 1 and the main container 5 are abutted with each other. The cap 7 is inserted inside the nozzle 74, and the inner plug 3 is fitted into the dispensing cap 7. At this time, since the nozzle 74 is inserted between the outer peripheral surface of the insertion tube portion 31 and the inner peripheral surface of the outer tube portion 30, the nozzle 74 interferes with the shoulder portion 23 and the flange portion 24 of the container body 2 of the refill container 1. There is nothing to do. Further, since the spout 33 of the inner plug 3 is closed by the seal portion 34, the contents in the container body 2 of the refill container 1 do not flow out at this time.

  Subsequently, as shown in FIG. 3, the refill container 1 is relatively pushed into the main container 5 side. That is, the refill container 1 in the inverted posture is moved downward relative to the main container 5 until the flange portion 24 of the container body 2 of the refill container 1 comes into contact with the upper end of the mounting cylinder portion 75 of the dispensing cap 7. Let Thereby, the sealing part 34 is pressed by the blade 8 of the pouring cap 7, the weakening part 36 is broken, the sealing part 34 is opened, and the spout 33 of the inner plug 3 is opened. At this time, since the plurality of protrusions 81 and 82 of the blade 8 are arranged side by side in the height order, the plurality of protrusions 81 and 82 press the seal portion 34 in order from the highest, weakening the seal portion 34. The part 36 is gradually broken from one side, and the seal part 34 is opened like a hinge lid.

  When the seal part 34 is opened, the contents in the container body 2 of the refill container 1 flow into the nozzle 74 of the discharge cap 7 from the outlet 33 of the inner plug 3 through the insertion cylinder part 31, It flows into the inside of the container body 6 of the main container 5 through the inside 74, and the contents in the refill container 1 are refilled in the main container 5. At this time, the air in the container body 6 of the main container 5 passes between the recovery port 76 of the dispensing cap 7 and the slit 78 of the nozzle 74, and is between the outer peripheral surface of the nozzle 74 and the inner peripheral surface of the inner cylinder portion 72. It flows out into the space, and further flows out through the air passage 25 of the container body 2 of the refill container 1. That is, the contents supplied from the refill container 1 are replaced with the air in the container body 6 of the main container 5. In addition, it is preferable that the refill container 1 mentioned above employ | adopts the container which can reduce naturally with the reduction | decrease of the content, or can be changed with external force. Also, a container in which only the inner layer or the inner container is reduced, such as a delamination container or a double container, can be employed. For example, the body 21 is deformed so as to be plastically deformed by pressing the container body. Thereby, the internal volume of the container main body 2 of the refill container 1 is forcibly reduced, the contents in the container main body 2 are positively pushed out, and the refill time is shortened.

  Further, as described above, when the contents in the refill container 1 are refilled in the main container 5, the flange portion 24 of the container body 2 of the refill container 1 described above is attached to the dispensing cap 7 of the main container 5. Since it is supported by the upper end of the part 75, the posture of the refill container 1 during the refilling operation of the contents is stable.

  According to the refill container 1 described above, the contents in the refill container 1 can be refilled into the main container 5 simply by fitting the inner cap 3 into the dispensing cap 7 of the main container 5 and pushing it in. Refilling work can be performed easily.

  In addition, the insertion tube portion 31 in a state where the inner plug 3 of the refill container 1 is fitted into the extraction cap 7 of the main container 5 and the insertion tube portion 31 of the inner plug 3 is inserted inside the nozzle 74 of the extraction cap 7. Since the inner seal portion 34 is opened and the spout 33 is opened, the contents are not spilled when the inner plug 3 and the discharge cap 7 are fitted, and the contents are also removed when the seal portion 34 is opened. It is hard to spill.

  Further, since it is not necessary to place the main container 5 in an inverted posture during the refilling operation, the contents in the main container 5 are not spilled even if the contents in the main container 5 remain. That is, the contents can be refilled even before the contents of the container 5 are used up.

  Further, the insertion tube portion 31 of the inner plug 3 is inserted inside the nozzle 74 of the dispensing cap 7, and the contents in the container body 2 of the refill container 1 from the spout 33 formed inside the insertion tube portion 31. Is poured out and refilled into the container body 6 of the main container 5, so that the contents easily flow into the container main body 6 of the main container 5 when the contents are refilled. That is, when the contents are refilled, the contents are poured out from the spout 33 arranged in the nozzle 74, and the contents flow into the container body 6 of the main container 5 through the nozzle 74. The contents poured out from the spout 33 of the stopper 3 are unlikely to collide with the nozzle 74 and turbulently or accumulate in the inner cylinder portion 72. Therefore, the contents can be refilled in a short time with respect to the main container 5 having the nozzle 74.

  Further, in the above-described refill container 1, when the inner plug 3 of the refill container 1 is fitted into the dispensing cap 7 of the main container 5, the outer peripheral surface of the insertion tube portion 31 and the inner peripheral surface of the outer tube portion 30 are Since the nozzle 74 is inserted in between, even if the distance from the tip of the nozzle 74 to the tip of the blade 8 is longer than the height of the mouth 20 of the container body 2 of the refill container 1, This can be dealt with by lengthening the cylinder part 30 and the insertion cylinder part 31 to the inner side (upper side in FIG. 2) of the container body 2 of the refill container 1. Therefore, the height of the mouth part 20 of the container body 2 of the refill container 1 and the protruding length of the insertion tube part 31 from the tip of the mouth part 20 can be kept low. As a result, the height of the refill container 1 can be reduced, and space saving can be achieved during sales display, storage, and transportation. Further, by changing the lengths of the outer cylinder part 30 and the insertion cylinder part 31 of the inner plug 3 without changing the height of the mouth part 20 of the container main body 2 of the refill container 1, the nozzle 74 of the dispensing cap 7 is changed. Therefore, it is possible to use the common container body 2 in the refill container 1 and to reduce the cost.

  Further, in the refill container 1 described above, the flange portion 24 of the container body 2 of the refill container 1 is supported on the upper end of the mounting cylinder portion 75 of the dispensing cap 7 of the main container 5 during the refill operation, so that the refill container 1 is stable. Therefore, it is difficult to spill the contents especially when the contents are refilled, and the refilling work can be easily performed. Moreover, since the upper end of the mounting cylinder part 75 is obstruct | occluded by the above-mentioned flange part 24, scattering of the contents at the time of the refilling of the contents can be prevented by this flange part 24.

As mentioned above, although embodiment of the refill container which concerns on this invention was described, this invention is not limited to above-described embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, in the above-described embodiment, the lid-shaped seal portion 34 connected to the inner edge of the spout 33 via the weakening portion 36 is disposed inside the insertion tube portion 31. The portion is not limited to the seal portion 34 described above. For example, as shown in FIG. 4, a plug-shaped seal portion 134 that is undercut fitted inside the spout 33 in the insertion tube portion 31 may be used. Furthermore, the seal portion in the present invention may be a film body that is stretched inside the spout 33 and can be broken by the blade 8.

  In addition, a film-like seal 37 is attached to the upper end of the above-described insertion cylinder portion 31, thereby reliably preventing the leakage of the contents in the refill container 1. The seal 37 can be omitted. Further, in the present invention, it is also possible to install a shrink film that covers the mouth 20 of the container body 2 and the inner plug 3 of the refill container 1 instead of the above-described seal 37 or on the above-described seal 37. is there.

  Further, in the above-described embodiment, the spout 33 and the seal portion 34 are disposed in the intermediate portion in the axial direction of the insertion tube portion 31, but in the present invention, the positions of the spout 33 and the seal portion 34 are appropriately changed. For example, the spout 33 and the seal portion 34 may be disposed at the upper end portion of the insertion tube portion 31.

  Moreover, in above-described embodiment, the upper end of the insertion cylinder part 31 protrudes higher than the upper end of the outer cylinder part 30 or the upper end of the mouth part 20 of the container main body 2 of the refill container 1 in the insertion cylinder part 31. However, according to the present invention, the upper end of the insertion tube portion 31 may be the same height as the upper end of the outer tube portion 30 and the upper end of the mouth portion 20 of the container body 2, or the upper end of the outer tube portion 30 and the container. It may be lower than the upper end of the mouth portion 20 of the main body 2.

  In addition, the refill container according to the present invention may be a container that contracts the bellows-like body portion of the container body and pushes out the contents, or may be a flexible pouch-shaped pouch container. . Furthermore, this invention may be the structure which refills the content by replacing the air in this container, and the content in a refilling container, without reducing the volume of a container main body.

  Further, in the above-described embodiment, the flange portion 24 is provided in the mouth portion 20 of the container body 2 of the refill container 1 and the air passage 25 is formed in the flange portion 24. The air passage 25 may not be formed in the portion 24, and the above-described flange portion 24 may be omitted.

  In addition, in the range which does not deviate from the main point of this invention, it is possible to replace suitably the component in above-mentioned embodiment with a well-known component, and you may combine the above-mentioned modification suitably.
