It is.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, the refill container according to the present embodiment is a pouch container, and includes a container body 1 and a spout 2 that constitute a bag part, as shown in FIGS. 1 (A) and 1 (B) and FIG.

  The container body 1 is formed from a sheet in which a film having an appropriate function, an aluminum foil, or the like is laminated, and the upper and lower sides and the side portions are heat-sealed. In addition, a well-known thing can be employ | adopted for the structure of the container main body 1, The raw material, a structure, a shape, etc. are not specifically limited.

  The spout 2 includes a substantially cylindrical (substantially cylindrical in this embodiment) pouring part 3 (see also FIGS. 3A and 3B) and a lid member 4 (see FIGS. 2A and 2B). Reference). In addition, the base end side of the extraction | pouring part 3 is fixed to the container main body 1 with a heat seal, for example.

  And the refill container of this embodiment is shown to FIG. 1 (B), after inserting the spout 2 from the front end side to the opening | mouth part C1 of the refill container C, as shown to FIG. 1 (A). As described above, the contents stored in the refill container (container body 1) can be refilled by lifting the extraction unit 3 and the container body 1 while maintaining the insertion state of the lid member 4 with respect to the mouth C1. It is configured so that it can be refilled (supplemented) to C.

  That is, the pouring part 3 constitutes the pouring path T (see FIG. 1 (B)) of the contents stored in the refill container (container body 1). In the state shown in FIG. The pouring path T is closed by a closing portion 5 provided on the distal end wall 4 a of the lid member 4.

  Specifically, the distal end wall 3a of the pouring portion 3 has a substantially single-letter-shaped through hole 6 (see FIGS. 1B, 3A, and 3B) that forms the downstream portion of the pouring passage T. ) And the closing portion 5 of the lid member 4 closes the extraction passage T by closing the through hole 6. That is, the closing part 5 has a shape capable of closing the through hole 6.

  Moreover, the extraction | pouring part 3 has the substantially cylindrical side wall 3b with which the front end wall 3a was provided in the front end side (refer FIG. 3 (A) and (B)), and the cover member 4 has a front end side at the front end side. It has the substantially cylindrical side wall 4b with which the wall 4a was connected (refer FIG. 2 (A) and (B)). And the pouring part 3 and the lid member 4 are in a state where the lid member 4 covers the pouring part 3, and the inner peripheral surface of the side wall 4b of the lid member 4 is along the outer peripheral surface of the side wall 3b of the pouring part 3. From the closing position (see FIG. 1 (A)) where the closing portion 5 closes the dispensing path T (through hole 6) to the open position (see FIG. 1 (B)) where the closing portion 5 stops closing (see FIG. 1 (B)), It can slide relative to the vertical direction.

  In addition, the distal end wall 4a of the lid member 4 has an opening 7 (two in the illustrated example) that allows the pouring path T to communicate with the outside of the lid member 4 when the closing portion 5 is in the open position (see FIG. 1B). Two openings 7) are provided (see FIGS. 1B and 2B). Therefore, when the blocking portion 5 is in the open position, the pouring path T is opened, and the contents can be poured out from the opening 7. The two openings 7 are closed by the distal end wall 3a of the extraction portion 3 when the closing portion 5 is in the closing position (see FIG. 1A).

  Next, the refilling method using the refill container of the present embodiment will be described with reference to a more specific configuration of the refill container.

  In the refill container of the present embodiment, when not in use (for example, at the time of sale), the closing part 5 is in the closing position as shown in FIG. The unused refill container (spout 2) is provided with a shrink film as the restricting means 8. The restricting means 8 is configured to restrict relative sliding between the extraction portion 3 and the lid member 4 and to release the restriction.

  Then, as shown in FIG. 4, the restricting means 8 that is a shrink film is a flange provided at a position where the lid member 4 does not cover the side wall 3 a of the extraction portion 3 from the peripheral edge of the tip wall 4 a of the lid member 4. 9 is provided to cover up to the periphery of 9. Further, in order to easily perform the operation of tearing the shrink film and removing it from the pouring portion 3 and the lid member 4, the shrink film is provided with appropriate cut edges and weakening lines (cut lines) not shown.

  On the other hand, the latching | locking part 10 is provided in the internal peripheral surface of the side wall 4b of the cover member 4 (refer especially FIG. 2 (A) and (B)), and with respect to this, the side wall 3b of the extraction | pouring part 3 is provided. On the outer peripheral surface, when the closing portion 5 is in the closing position (see FIG. 1A), the first locked portion 11 that the locking portion 10 locks, and when the closing portion 5 is in the open position ( 1B) is provided with a second locked portion 12 that the locking portion 10 locks (see particularly FIG. 3A). In the present embodiment, the locking portion 10 is a total of four protrusions provided at substantially equal intervals in the circumferential direction of the inner peripheral surface of the side wall 4b of the lid member 4, and includes the first locked portion 11 and the first locking portion. The two locked portions 12 are annular grooves provided on the outer peripheral surface of the side wall 3 b of the extraction portion 3.

  Therefore, in the refill container in an unused state, the blocking of the through hole 6 of the pouring part 3 by the closing part 5 of the lid member 4 and the blocking of the opening 7 of the lid member 4 by the tip wall 3a of the pouring part 3 The sealing of the container is ensured by the locking of the dispensing portion 3 to the first locked portion 11 by the locking portion 10 of the lid member 4 and the shrinkage force of the shrink film (regulating means 8).

  And in order to perform the refilling operation | work with respect to the refilling container C using the refilling container in an unused state, first, the regulation means 8 (shrink film) is torn and removed. Thereby, the restriction | limiting of the relative slide of the extraction | pouring part 3 and the cover member 4 by the control means 8 is cancelled | released.

  Subsequently, when the spout 2 (lid member 4) is inserted into the mouth portion C1 of the refill container C (see FIG. 1A), the flange 13 provided on the side wall 4b of the lid portion 4 becomes the mouth portion C1. The refill container is turned upside down.

  Here, when the spout 2 (lid member 4) is inserted into the mouth portion C1 of the refill container C, the spout 2 is simply turned downward, so that the locking portion 10 and the extraction portion 3 of the lid member 4 Since the 1st to-be-latched part 11 is latching, the cover member 4 does not slide and remove | deviate naturally from the extraction | pouring part 3, and falls.

  Then, the extraction | pouring part 3 and the container main body 1 are lifted, maintaining the insertion state of the cover member 4 with respect to the opening part C1. Here, in order to prevent the lid member 4 from being lifted together when lifting the pouring part 3 and the container main body 1, the lid part 4 of the lid member 4 is provided with the collar part 9 of the pouring part 3. What is necessary is just to hold down the part exposed from the missing part 9a with the finger | toe (hand), and press the collar part 13 to the opening part C1. In addition, although the missing part 13a (refer FIG. 2 (A) and (B)) is provided also in the collar part 13 of the cover member 4, it is made to overlap | superpose FIG. 2 (B) and FIG. 3 (B). As is clear from the comparison, the phase of the missing portion 9a and the missing portion 13a is shifted, and a part of the flange portion 13 of the lid member 4 is always exposed from the missing portion 9a of the flange portion 9 of the extraction portion 3. Will do.

  Moreover, in order to lift the extraction | pouring part 3 and the container main body 1, what is necessary is just to have a part which is easy to hold in either the extraction | pouring part 3 and the container main body 1, for example, in the collar part 9 of the extraction | pouring part 3, the cover member 4 A gap is formed between the portion located above the missing portion 13a provided in the flange portion 13 and the mouth portion C1 of the refill container C, and is easier to hold than other portions in the flange portion 9. Therefore, it is possible to have this part.

  When the extraction unit 3 and the container body 1 are lifted as described above, the contents of the refill container (container body 1) are poured into the refill container C as shown in FIG.

  By the way, as mentioned above, the missing part 13a is provided in the collar part 13 of the lid member 4, and the content of the refill container (container body 1) is poured into the refill container C in the missing part 13a. In addition to the missing portion 13a, in the state where the collar 13 is engaged with the peripheral edge of the mouth C1 in addition to the missing part 13a. For example, a plurality of air vent hole portions 13b that allow the space between the side wall 4b of the lid member 4 and the mouth portion C1 to communicate with the outside of the mouth portion C1 may be provided (particularly, refer to FIG. 2B). If comprised in this way, with the extraction of the contents from the refill container (container body 1) into the refill container C, the air in the refill container C will also flow out from the hole portion 13b. Therefore, it is possible to smoothly inject (refill) the contents into the refill container C accordingly.

  In addition, in order to make the space for the air venting between the side wall 4b of the lid member 4 and the mouth part C1 in a state where the collar part 13 is locked to the periphery of the mouth part C1, In the embodiment, the outer diameter of the side wall 4b of the lid member 4 is smaller than the inner diameter of the mouth portion C1, but in addition to this configuration, for example, several locations on the outer peripheral surface of the side wall 4b (for example, equally spaced in the circumferential direction) Four ribs) are provided with vertical ribs (not shown) in contact with the inner surface of the mouth portion C1, or instead of these configurations, for example, the outer diameter of the side wall 4b of the lid member 4 and the inner diameter of the mouth portion C1 Can have substantially the same diameter, and a vertical groove (not shown) can be provided on the outer peripheral surface of the side wall 4b. In any case, the air venting space is formed, and the side wall 4b of the lid member 4 can be fitted and fixed in the mouth portion C1 through the vertical rib or directly. While the refill container (container body 1) is connected to the refill container C with good stability, while the contents are being poured from the refill container (container body 1) into the refill container C, It is also possible to let go of the refill container (container body 1).

  Further, when lifting the pouring part 3 and the container body 1, the latching part 10 of the lid member 4 detached from the first latching part 11 of the pouring part 3 is latched to the second latching part 12. Then, even if it releases a hand from the extraction | pouring part 3 and the container main body 1, it will become possible to maintain a state as it is.

  And if the injection | pouring (refilling) of the content with respect to the refilling container C is completed, the spout 2 (lid member 4) should just come out from the opening part C1.

  As described above, in order to refill the contents of the refill container C using the refill container of the present embodiment, the spout 2 is inserted into the mouth portion C1 of the refill container C, and then the lid member. It is only necessary to lift (slide upward) the pouring part 3 and the container main body 1 while pressing 4, and the refilling operation is simple. Further, at the time of refilling, after inserting (connecting) the spout 2 of the refill container into the refill container C, the discharge part 3 and the container body 1 are slid relative to the lid member 4 and sealed. The structure that solves the problem prevents the contents from spilling.

  Here, examples of the contents accommodated in the container body 1 (contents to be refilled in the refill container C) include detergents, shampoos, rinses, and the like, as long as the above refilling work can be performed. There is no particular limitation.

  Further, the refill container C has a mouth part C1 into which the lid member 4 of the spout 2 can be inserted and can perform the above refilling work, and is limited to the above-described polypropylene bottles and the like. It is not something.

  On the other hand, the material of the pouring part 3 may be any material depending on the configuration of the container body 1, and for example, polyethylene (PE, LLDPE), polypropylene (PP), or the like can be used.

  On the other hand, the lid member 4 has a closing portion 5 that closes the through hole 6 of the extraction portion 3, and it is necessary to securely seal the through hole 6. It is preferable to use polyethylene or the like that has flexibility and allows the fitting (biting) between the closed portion 5 and the through hole 6 to be favorable, and an elastic material can also be used.

  Of course, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention. For example, the following modifications can be given.

  The refill container of the above embodiment is upright when the spout 2 is facing up (see FIG. 4), and is inverted when the spout 2 is facing down (see FIGS. 1A and 1B). It corresponds to the state. However, the refill container may be configured to stand upright with the spout 2 facing downward (see FIGS. 1A and 1B).

  The container body 1 is not limited to a pouch container, and may be a bottle such as a plastic bottle or a carton. That is, the material, shape, capacity, and the like of the container body 1 may be any one that meets the purpose of refilling the contents of the refill container C.

  The extraction portion 3 is not limited to a substantially cylindrical shape, and may be a substantially elliptical cylindrical shape, a rectangular tubular shape, or the like.

  Moreover, the width of the substantially one-letter-shaped through-hole 6 of the pouring part 3 shown in FIG. 3B (the width in the left-right direction in FIG. 3B) is smaller than that illustrated depending on the properties of the contents. Of course, the through hole 6 may have a substantially cross-shaped or star-shaped shape instead of a substantially single-letter shape. On the other hand, the shape of the blocking portion 5 may be any shape that can close the through hole 6. That is, the pouring part 3 and the lid member 4 are configured to be changeable between a state in which the pouring path T is closed and a state in which the pouring path T is opened by relative sliding in the axial direction of the pouring part 3. That's fine. Therefore, for example, the opening 6 of the lid member 4 can be provided not on the tip wall 4a of the lid member 4 but on the side wall 4b, or on both the tip wall 4a and the side wall 4b.

  The attachment part 3c (see FIGS. 1 (A) and (B) and FIG. 3 (B)) to the container body 1 provided on the proximal end side of the extraction part 3 may be substantially cylindrical, It is good also as a boat form shape etc. which are utilized for a spout pouch. Further, when the container body 1 is, for example, a bottle, the pouring part 3 is engaged with the container body 1 with a screw, and when the container body 1 is, for example, a carton, the bowl shape provided in the pouring part 3 is a carton. The attachment method according to the structure of the container main body 1 can be used, such as bonding to the adhesive layer on the inner surface.

  In the side wall 3b of the pouring part 3, the portion that is covered by the side wall 4b of the lid member 4 when the closing portion 5 is in the closing position and that is not covered when the closing portion 5 is in the open position is given light transmittance ( The portion passing through the side wall 3b of the pouring part 3 during refilling shown in FIG. 1B is directly or indirectly as a shadow from the outside of the portion of the side wall 3b. It may be made visible so that it can be easily grasped that refilling has been completed. In this case, for example, if the lid member 4 has light blocking properties, external light can be prevented from entering the inside of the side wall 3b and the contents can be prevented from being altered by the incident light. Can do.

  The eaves part 9 of the extraction | pouring part 3 is not restricted to a substantially ring shape, A petal shape, a cross shape, etc. may be sufficient. Further, it is not necessary to provide the collar portion 9, and in this case, since the collar portion 9 cannot be grasped naturally, the state shown in FIG. 1A is changed to the state shown in FIG. For example, it is conceivable that the extraction unit 3 and the container body 1 are pulled up by grasping the side wall 3b of the extraction unit 3.

  The number of protrusions constituting the locking portion 10 of the lid member 4 is not limited to four. In addition, the first locked portion 10 and the second locked portion 12 are each a protrusion, and the locking portion 10 is an annular groove that is locked by each protrusion. The engaging portions 11 and 12 may be engaged with each other, and various configurations can be adopted. Further, the locking portion 10 may be provided on the outer peripheral surface of the extraction portion 3, and the first locked portion 11 and the second locked portion 12 may be provided on the inner peripheral surface of the lid member 4.

  The flange portion 13 of the lid member 4 is configured to be locked to the periphery of the mouth portion C1 when the lid member 4 is inserted into the mouth portion C1 of the refill container C and to maintain the inverted posture of the refill container. The shape is not limited to a substantially ring shape, and may be a petal shape or a cross shape.

  FIG. 2B shows an example in which a total of six hole portions 13b are provided in the flange portion 13 of the lid member 4. The number of hole portions 13b, the shape and size of each hole portion 13b, and the like are as follows. Various changes can be made. In addition, for the air bleeding, the space between the side wall 4b of the lid member 4 and the mouth portion C1 is communicated with the outside of the mouth portion C1 in a state where the missing portion 13a is engaged with the periphery of the mouth portion C1. If it is configured as a missing portion, the same function as the hole portion 13b (the air bleeding function of the refill container C) can be exerted also on the missing portion 13a. In this case, the missing portion 13a and the hole portion 13b In order to obtain the necessary air bleeding function, That is, it is possible to provide only one of the missing portion 13a and the hole portion 13b.

  A label (not shown) is attached to the tip of the spout 2 so as to cover substantially the entire tip surface (upper surface) of the spout 2 or to cover the upper opening 8a (see FIG. 4) of the regulating means 8 that is a shrink film. In this case, the foreign substance is refilled from the gap between the tip wall 3a of the pouring part 3 and the tip wall 4a of the lid member 4 by such a label. It is possible to prevent entry into the container.

  As shown in FIG. 5, a cylindrical portion 14 is continuously provided at the periphery of the flange portion 13 provided on the side wall 4 b of the lid member 4, and the male screw provided in the mouth portion C <b> 1 of the refill container C is provided on the cylindrical portion 14. You may provide the engaging part 14a engaged with C2. In this case, after the spout 2 is inserted into the mouth portion C1, the lifting portion 3 and the container body 1 are lifted while maintaining the insertion state of the lid member 4 with respect to the mouth portion C1 (see FIG. 1B). By engaging the engaging portion 14a with the male screw C2, the trouble of pressing the flange portion 13 of the lid member 4 against the peripheral edge of the mouth portion C1 can be saved, and the lifting operation of the pouring portion 3 and the container body 1 is easy. In addition, it is possible to reliably prevent the lid member 4 from accidentally coming out of the mouth portion C1 and spilling the contents, and if the container body 1 itself has shape retention, the contents can be poured. It is also possible to let go of the refill container or the refill container C while taking out.

  As shown in FIGS. 6 (A) to 6 (C), the regulating means 8 is provided on either one of the flange portion 9 of the extraction portion 3 or the flange portion 13 of the lid member 4 (in the illustrated example, the flange portion 13). The engagement portion 15 and the engaged portion 16 that is provided on the other flange (the flange portion 9 in the illustrated example) and engages with the engagement portion 15 may be used.

  That is, as shown in FIGS. 6 (A) and 6 (C), the engaging portion 15 has a substantially U-shaped longitudinal section that is continuous with the flange 13 and is bent so as to hold the other flange 9. A recess (through hole in the illustrated example) 15a is provided on the tip side. Moreover, the engaged part 16 is a convex part provided in the position corresponding to the recessed part 15a in the surface at the side of the container main body 1 of the collar part 9, as shown to FIG. 6 (A) and (B).

  Then, as shown in FIG. 6A, in a state where the engaging portion 15 (concave portion 15a) is engaged with the engaged portion (convex portion) 16, the dispensing portion between the dispensing portion 3 and the lid member 4 The relative sliding in the axial direction of 3 is restricted, and from this state, the pouring portion 3 and the lid member 4 are poured out until the engaging portion 15 comes to a position corresponding to the missing portion 9 a of the flange portion 9. By relatively rotating around the axis of the portion 3, the engagement between the engagement portion 15 and the engaged portion 16 is released, and the restriction is released.

  Here, since it is necessary to rotate the extraction | pouring part 3 and the cover member 4 around the axis | shaft of the extraction | pouring part 3, the through-hole 6 of the extraction | pouring part 3 centers on the axis | shaft of the extraction | pouring part 3. The closing portion 5 of the lid member 4 has a shape capable of closing the substantially circular through hole 6 (for example, a substantially cylindrical shape slightly larger than the through hole 6). (See FIGS. 6A and 6C). As shown in FIG. 6A, the tip wall 3a is configured not to enter the opening 7.

  The engaging portion 15 is simply engaged with the flange portion 9 so that the engaging portion 15 is not provided with the concave portion 15a and the flange portion 9 is not provided with the engaged portion 16 that is a convex portion. You may do it. In this case, the flange 9 itself becomes the engaged portion 16.

  FIG. 6C shows an example in which the engaging portion 15 is partially provided on the flange portion 13, but the engaging portion 15 may be provided on the entire flange portion 13. Good.

  6 (A) to 6 (C), if the extraction portion 3 and the lid member 4 are relatively rotated around the axis of the extraction portion 3, the engaging portion 15 and the engaged portion will be shown. However, instead of such a configuration, for example, the boundary portion between the flange portion 13 and the engagement portion 15 is thinned, and the engagement portion 15 is The engagement between the engagement portion 15 and the engaged portion 16 (the flange portion 9) may be released by extending outward and expanding.

  Moreover, it replaces with the structure which provides the engaging part 15 in the collar part 13, and provides the to-be-engaged part 16 in the collar part 9 (or it uses the collar part 9 as the to-be-engaged part 16), and is engaging part in the collar part 9. 15 and a configuration in which the engaged portion 16 is provided in the flange portion 13 (or the flange portion 13 is used as the engaged portion 16) may be employed.

  Needless to say, the plurality of modifications described above may be combined as appropriate.
