The slit 78 extends from the tip end to the base end of the nozzle 74 and is connected to the slit 76 of the inner cylinder portion 72 described above.

  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 refill container 1 and the mouth parts 20 and 60 of the main container 5 are brought into contact with each other so that the communicating cylinder part 39 (the fitting cylinder part 32 and The rising cylinder portion 33) is inserted outside the nozzle 74 of the pouring cap 7 of the container 5, and the lid 3 is fitted to the pouring cap 7. At this time, since the spout 37 of the lid 3 is closed by the closing portion 35, 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. As a result, the seal cylinder part 34 engages with the bottom part 73 (the outer peripheral part of the base end part of the nozzle 74) of the dispensing cap 7 and deforms into a bellows shape, and the tip of the seal cylinder part 34 is the bottom part of the extraction cap 7 The outer peripheral portion of the base end portion of the nozzle 74 is sealed by the seal cylinder portion 34. That is, the gap between the front end surface of the communication tube portion 39 of the lid 3 and the upper surface of the bottom portion 73 of the pouring cap 7 is closed over the entire circumference by the seal tube portion 34, and the entire nozzle 74 of the pouring cap 7. Is covered with the communication tube portion 39 and the seal tube portion 34 of the lid 3.

  In addition, by pushing the refill container 1 relatively toward the main container 5, the closing portion 35 is pressed by the tip of the nozzle 74 of the dispensing cap 7, and the closing portion 35 is refilled from the inside of the spout 37 of the lid 3. 1 is pushed out to the inside of the container body 2 and the spout 37 of the lid 3 is opened. As a result, the contents in the container body 2 of the refill container 1 flow into the inside of the nozzle 74 of the dispensing cap 7 from the spout 37 and flow into the container body 6 of the main container 5 through the nozzle 74. 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 flows out from the slit 76 of the discharge cap 7 through the inner cylindrical portion 72 of the discharge cap 7, and the contents supplied from the refill container 1 are discharged. The air in the container body 6 of the container 5 is replaced.

  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.

  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 lid 3 of the refill container 1 into the dispensing cap 7 of the main container 5 and pushing it in. Refilling work can be performed easily.

  In addition, the lid 3 of the refill container 1 is fitted into the pouring cap 7 of the main container 5, and the communication tube portion 39 of the lid 3 is fitted to the outside of the nozzle 74 of the pouring cap 7. Since the spout 37 is opened, the contents are not spilled when the lid 3 and the spout cap 7 are fitted together, and the contents are hardly spilled even when the spout 37 is opened. Furthermore, when the contents in the refill container 1 are refilled into the main container 5, the outer peripheral portion of the base end portion of the nozzle 74 is sealed by the seal tube portion 34, and the communication tube portion 39 and the seal tube of the lid 3 are sealed. Since the entire nozzle 74 is covered by the portion 34, even if the content poured out inside the nozzle 74 flows out from the slit 78 of the nozzle 74, the content flows out to the outside of the insertion tube portion 39. Therefore, it is possible to prevent the contents from spilling when the contents are refilled.

  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, in the refill container 1 described above, the seal cylinder part 34 is formed integrally with the communication cylinder part 39 and is formed thinner than the communication cylinder part 39 (rising cylinder part 33), thereby increasing the number of parts. The seal cylinder part 34 which is easy to deform | transform is formed. Therefore, an increase in cost can be suppressed.

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 cap-like lid body 3 screwed to the outside of the mouth portion 20 of the container body 2 is provided. However, the present invention has a structure other than screwing (for example, undercut fitting). The lid 3 may be attached to the mouth portion 20. Moreover, the present invention can also use an inner plug-like lid that is fitted inside the mouth portion 20.

  In the above-described embodiment, the spout 37 is formed at the lower end of the communication tube portion 39 (fitting tube portion 32). However, in the present invention, the axial position of the spout 37 can be changed as appropriate. is there. For example, a spout may be formed at an axially intermediate portion (a portion between the fitting tube portion 32 and the rising tube portion 33) of the communication tube portion 39, and an upper end portion of the communication tube portion 39 (the rising tube portion 33). A spout may be formed in.

  Further, in the above-described embodiment, the closing portion 35 detachably fitted inside the spout 37 is provided. However, the present invention is connected to the inner edge of the spout 37 via the weakened portion. It may be a closed portion, or may be a film-like closed portion that is stretched inside the spout 37 and can be broken by the nozzle 74.

Further, in the above-described embodiment, the straight cylinder-shaped seal cylinder part 34 whose outer diameter is substantially the same as that of the rising cylinder part 33 is provided. For example, the inner diameter may be a seal cylinder part that is substantially the same diameter as the rising cylinder part 33 and the outer diameter is smaller than the rising cylinder part 33, or the inner diameter is larger than the rising cylinder part 33. The seal cylinder part whose outer diameter is smaller than the rising cylinder part 33 may be sufficient. Furthermore, the seal tube portion in the present invention is not limited to a straight tube shape, and may be, for example, a taper tube-shaped seal tube portion that is gradually reduced in diameter or expanded toward the top.
Further, in the above-described embodiment, the seal tube portion 34 is formed integrally with the communication tube portion 39, but the present invention can also provide a seal tube portion that is separate from the communication tube portion. For example, a configuration may be adopted in which a cylindrical elastic member (seal cylinder part) is fitted and connected to the distal end part of the communication cylinder part 39.
In the above-described embodiment, the seal tube portion 34 engages with the outer peripheral portion of the base end portion of the nozzle 74 and deforms into a bellows shape. However, in the present invention, the seal tube portion is deformed into a bellows shape. It is not limited, and when the seal cylinder part 34 is engaged with the outer peripheral part of the base end part of the nozzle 74, it may be deformed into another shape. For example, the diameter of the seal cylinder 34 may be increased when the seal cylinder 34 is engaged with the outer peripheral portion of the base end of the nozzle 74. Further, the seal cylinder portion 34 may be configured to be in pressure contact with the outer peripheral surface of the nozzle 74.

  Further, in the present invention, a film-like seal may be attached to the upper end of the communication tube portion 39 in order to reliably prevent the contents in the refill container 1 from leaking out. Alternatively, it is also possible to install a shrink film covering the mouth 20 and the lid 3 of the container body 2 of the refill container 1 from above the above-described seal.

  In addition, the refill container according to the present invention may be, for example, a container that shrinks the bellows-like body portion of the container body to push out the contents, or may be a flexible pouch-shaped pouch container. Good. 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.

  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.
