  The container described in Patent Document 1 has the following inconvenience because the inner container is fixedly connected to a cap attached to the outer container.

  (1) When the contents are supplied to the outer container, if the cap is removed from the outer container, the inner container fixedly connected to the cap is pulled out from the outer container. The contents of the outer container are adhered to the outer surface of the pulled out inner container, which contaminates the surroundings.

  (2) According to the above (1), since it is necessary to pull out the inner container fixedly connected to the cap from the outer container, it is necessary to make the outer diameter of the inner container smaller than the opening diameter of the outer container. The content of is limited. If the air capacity of the contents of the inner container is small in the foam generation container, there is a risk that the foam generation will be poor.

  An object of the present invention is to replenish the contents of the outer container without pulling the inner container out of the outer container.

  According to the first aspect of the present invention, the inner container is placed in the outer container, the cap of the outer container is covered with the cap attached to the outer container, and the opening of the inner container and the opening of the inner container are respectively covered. A container that enables discharge of the contents and at least the contents of the outer container can be replenished to the outer container from the opening of the outer container, and a joint is attached to the opening of the outer container. The opening of the inner container is connected to the joint.

  A joint was attached to the opening of the outer container to which the cap was attached, and the opening of the inner container was connected to this joint. Therefore, even if the cap is removed from the outer container, the inner container is still accommodated in the outer container by the joint. Therefore, the contents can be replenished to the outer container without pulling out the inner container from the outer container.

  The foam generation container 1 shown in FIGS. 1 and 2 is a double container in which an outer container 10 made of a flexible resin and an inner container 20 made of a flexible resin are connected by a joint 30, and is attached to the outer container 10. The foam generating member 50 is provided in the discharge path 41 of the base cap 40 to be used, and the overcap 60 is attached to the base cap 40.

  In the foam generation container 1, the inner container 20 formed of an inner bag is placed in the outer container 10, and the opening 10 </ b> A of the outer container 10 and the opening 20 </ b> A of the inner container 20 are covered with a base cap 40 that is attached to the outer container 10. The foam generation container 1 discharges the foamable solution as its contents from the opening 10A of the outer container 10, and also discharges the air as its contents from the opening 20A of the inner container 20, and bubbles these foamable solution and air into the foam. Mixing is performed by the mixers 51 and 52 of the generating member 50, and the mixture is passed through the net of the net holder 53 to form bubbles, and the bubbles are discharged from the discharge port 40 </ b> A of the base cap 40 to the outside. The foam generation container 1 enables the contents of the outer container 10 to be replenished to the outer container 10 through the opening 10A using a refill bottle 2 described later.

  Hereinafter, (A) a connection structure between the outer container 10 and the inner container 20 and (B) a structure for refilling contents into the outer container 10 will be described.

(A) Connection structure of outer container 10 and inner container 20 As shown in FIGS. 1 and 2, the foam generation container 1 is driven by attaching a joint 30 inside the opening 11 (forming the opening 10A) of the outer container 10. Then, the opening portion 21 (forming the opening 20 </ b> A) of the inner container 20 is press-fitted and connected to the joint 30. The foam generation container 1 is attached by screwing a base cap 40 to the outside of the opening 11 of the outer container 10, and screwing and attaching an overcap 60 to the outer periphery of the base cap 40. The plug 61 on the inner surface of the ceiling is tightly inserted into the discharge port 40A of the base cap 40, and the entire foam generation container 1 is sealed.

  During the production of the foam generating container 1, an inner container 20 having an outer diameter larger than the diameter of the opening 10A of the outer container 10 is prepared, and the inner container 20 having a smaller outer diameter is sucked by sucking the inner pressure of the inner container 20. The container 10 is inserted into the outer container 10 through the opening 10A and stored, and the inner pressure of the inserted inner container 20 is restored by pressurization, so that the inner container has a larger outer diameter than the opening 10A. 20 can be paid. The joint 30 is connected to the inner container 20 before the inner container 20 is stored in the outer container 10, and is attached to the outer container 10 after the inner container 20 is stored in the outer container 10.

  As shown in FIGS. 3 to 5, the joint 30 is bridged between the inner periphery of the lower end inner periphery of the outer cylinder portion 30 </ b> A and the intermediate outer periphery of the columnar body 30 </ b> B so that the columnar body 30 </ b> B is disposed at the center of the outer cylinder portion 30 </ b> A. The cross-linked portion 30C is provided. In this specification, the upper and lower sides of the container 1 and each component are the state in which the bottom of the container 1 is placed upright on the table (FIG. 1), the top side of the container 1 is up, The bottom side is called the bottom.

  The joint 30 is an attachment portion 31 that is driven and attached to the inner periphery of the opening 11 of the outer container 10 by using the outer cylinder portion 30A. The attachment portion 31 has a flange portion 31A whose diameter is expanded to the upper end surface of the opening portion 11 of the outer container 10 at the upper end portion of the outer cylinder portion 30A, and the flange portion 31A abuts on the upper end surface of the opening portion 11. It is driven into the inner periphery of the opening 11 to the position.

  The joint 30 has a lower end portion of the columnar body 30 </ b> B as a connection portion 32 connected to the opening 21 of the inner container 20. The connection portion 32 includes an inner cylinder portion 32A and an outer cylinder portion 32B that protrude downward so as to form a double cylinder around the central axis of the columnar body 30B, and an annular gap between the inner cylinder portion 32A and the outer cylinder portion 32B. Opening downward, the opening 21 of the inner container 20 is press-fitted and connected to the annular gap.

  The joint 30 is an annular gap penetrating vertically between the outer cylinder portion 30A and the columnar body 30B, and communicates a space that is not blocked by the bridging portion 30C to the inside of the outer container 10 and is discharged from the opening 10A of the outer container 10. This is the outer passage 33 for the foaming solution to be applied.

  The joint 30 has a columnar body 30 </ b> B as a hollow nozzle portion 35, communicates a hollow hole penetrating up and down the nozzle portion 35 to the inside of the inner container 20, and is for air discharged from the opening 20 </ b> A of the inner container 20. The inner passage 34 of the above.

  In the foam generation container 1, the inner container 20 is placed in the outer container 10, and the joint 30 connected to the opening 21 of the inner container 20 is attached to the opening 11 of the outer container 10. The above-described outer passage 33 and inner passage 34 face the upper outside of the openings 10A and 20A of the outer container 10 and the inner container 20. Then, when the base cap 40 is screwed and attached to the outside of the opening 11 of the outer container 10, the discharge of the base cap 40 in which the foam generating member 50 (mixers 51 and 52, net holder 53) is incorporated. The passage 41 communicates with both the outer passage 33 and the inner passage 34 of the joint 30 described above.

  Accordingly, when the foam generating container 1 is used, when the user squeezes the outer container 10 of the foam generating container 1 turned upside down with fingers, and the internal pressure of the outer container 10 increases, the internal pressure of the outer container 10 is increased in the outer container 10. The foamable solution is discharged from the opening 10A through the outer passage 33 of the joint 30 to the discharge passage 41 of the base cap 40, and the air in the inner container 20 squeezed by the inner pressure of the outer container 10 is also passed from the opening 20A to the inner passage of the joint 30. As a result of being discharged to the discharge path 41 of the base cap 40 via 34, these foam generation solution and air are mixed and foamed by the foam generation member 50 of the discharge path 41 and discharged to the outside from the discharge port 40 </ b> A of the base cap 40. The

  When replenishing the contents of the outer container 10, the joint 30 attached to the opening 11 of the outer container 10 can be exposed to the outside simply by removing the base cap 40 from the opening 11 of the outer container 10. For example, the foamable solution of the refill bottle 2 can be supplied into the outer container 10 from the outer passage 33 of the joint 30.

According to the foam production | generation container 1, there exist the following effects.
(a) The joint 30 was attached to the opening 11 of the outer container 10 to which the base cap 40 was attached, and the opening 21 of the inner container 20 was connected to the joint 30. Therefore, even if the base cap 40 is removed from the outer container 10, the inner container 20 is still accommodated in the outer container 10 by the joint 30. Therefore, the contents can be replenished to the outer container 10 without pulling out the inner container 20 from the outer container 10.

  (b) When the contents are replenished to the outer container 10 according to the above (a), the contents of the outer container 10 attached to the outer surface of the inner container 20 are not pulled out from the outer container 10. Does not pollute the surroundings.

  (c) According to the above (a), since it is not necessary to pull out the inner container 20 from the outer container 10, it is not necessary to make the outer diameter of the inner container 20 smaller than the opening diameter of the outer container 10, and the inner capacity of the inner container 20 is increased. Not limited.

  (d) In the foam generation container 1 in which the foam generation member 50 is provided in the base cap 40, the air capacity as the contents of the inner container 20 is increased and sufficiently increased by the above-mentioned (c) to improve the foam generation. it can.

(B) Structure for Supplying Contents to Outer Container 10 The foam generation container 1 also uses the joint 30 attached to the opening 11 of the outer container 10 as the bottle holding member 70. As described above, the joint 30 serving as the bottle holding member 70 includes the attachment part 31 attached to the opening part 11 of the outer container 10, the connection part 32 connected to the opening part 21 of the inner container 20, and the outer container 10. Nozzle portion 35 (columnar shape) that includes an outer passage 33 for the foamable solution discharged from the opening 10A and an inner passage 34 for the air discharged from the opening 20A of the inner container 20, and forms the inner passage 34. The outer periphery of the body 30B) constitutes a bottle holding portion 71 that loosely holds the inner diameter of the opening 2A of the refill bottle 2. Thereby, the joint 30 which is the bottle holding member 70 has the opening 2 </ b> A of the refill bottle 2 which is inverted by the user's finger as shown in FIGS. 6 and 7 in the opening 10 </ b> A of the outer container 10. Even if the finger is released from the refill bottle 2 in the state of being loosely inserted into the bottle holding portion 71, the inverted state of the refill bottle 2 is held.

  Here, the bottle holding part 71 of the joint 30 which is the bottle holding member 70 is composed of the columnar body 30B forming the nozzle part 35 of the joint 30 as described above. The bottle holding portion 71 includes an inner diameter support portion 72A that supports and supports only a part of the inner diameter of the opening 2A of the refill bottle 2 on the outer periphery of the columnar body 30B, and the opening of the refill bottle 2 And an end surface support portion 72B that abuts and supports only a part of the end surface of 2A. In the present embodiment, the periphery of the outer periphery of the columnar body 30 </ b> B is configured so that the opening 2 </ b> A of the refill bottle 2 can be loosely coaxially inserted into the columnar body 30 </ b> B (nozzle portion 35) as the bottle holding portion 71 of the joint 30. For example, L-shaped plate-like rib bodies 73 are provided at four positions that are spaced by 90 degrees in the direction. The four rib bodies 73 have a cross radial shape projecting outward from the outer periphery of the columnar body 30B. Each rib body 73 includes a small rib 73A that is provided on the distal end side in the axial direction away from the bridging portion 30C of the columnar body 30B and has a small amount of protrusion outward from the outer periphery of the columnar body 30B, and a bridging portion of the columnar body 30B. The large rib 73B is provided near the 30C and discharges from the outer periphery of the columnar body 30B to the outside larger than the small rib 73A. The small rib 73A is an L-shaped vertical side, and the large rib 73B is an L-shape. The horizontal side of the. The inner diameter support portion 72A of the bottle holding portion 71 is formed by the side surface of the small rib 73A protruding outward from the outer periphery of the columnar body 30B, and the end surface support portion 72B is outward from the outer periphery of the columnar body 30B than the small rib 73A. The upper surface of the protruding large rib 73B is assumed. In plan view of the joint 30 (FIG. 7B), the outer diameter of the circle circumscribing the four inner diameter support portions 72A (small ribs 73A) of the columnar body 30B is larger than the inner diameter of the opening 2A of the refill bottle 2. The outer diameter of the circle circumscribing the four end surface support portions 72B (large ribs 73B) is slightly larger than the outer diameter of the end surface of the opening 2A of the refill bottle 2.

  Thereby, in the foam production | generation container 1, when the base cap 40 is removed from the opening part 11 of the outer container 10, and the content is supplied to the outer container 10 from the refill bottle 2, the refill bottle turned upside down. 2A, a part of the inner diameter of the opening 2A is supported on the inner diameter support 72A of the bottle holding part 71 (the side surface of the small rib 73A of the rib 73 of the columnar body 30B), and the opening 2A of the refill bottle 2 is supported. A part of the end face is abutted and supported by the end face support part 72B of the bottle holding part 71 (the upper surface of the large rib 73B of the rib body 73 of the columnar body 30B). As shown in FIG. 7A, the inner diameter support part 72A and the end face support part 72B of the bottle holding part 71 are opened in the columnar body 30B (nozzle part 35) as the bottle holding part 71. A passage 3 is formed between the inner diameter and end face of 2A and the bottle holding portion 71 (columnar body 30B, nozzle portion 35), and this passage 3 flows out of the foamable solution from the refill bottle 2 to the outer container 10. It becomes a passage, and at the same time, a replacement passage for air flowing into the refill bottle 2 from the outside.

  Furthermore, in the foam generation container 1, the opening 2 </ b> A of the refill bottle 2 is loosely inserted into the columnar body 30 </ b> B (nozzle portion 35) that is the bottle holding portion 71 of the joint 30, and the foamable solution of the refill bottle 2. So that the effervescent solution in the refill bottle 2 does not enter the inner container 20 when flowing out from the passage 3 around the bottle holding part 71 (columnar body 30B, nozzle part 35) to the outer container 10. The passage diameter (nozzle diameter 35A) of the inner passage 34 formed by the nozzle portion 35 is set to more than 1.0 mm and 1.5 mm.

  That is, in the foam generation container 1 described above, the inner container 20 is in the form of an inner bag, the weight of the outer container 10 not filled with contents is 13 g, and the capacity of the inner container 20 not filled with contents is 72 ml. An experiment was conducted in which the foamable solution in the refill bottle 2 was discharged so as to fall over the entire upper end surface where the nozzle diameter 35A of the nozzle portion 35 opened, and the solution adhered to the outer surface of the inner container 20 was removed by this experiment. The weight of the inner container 20 before and after the experiment (inner bag weight) was measured, and the difference between the measured values was defined as the amount of liquid entering the inner container 20 from the nozzle diameter 35A of the nozzle portion 35. The results of Tables 1 to 5 were obtained for various nozzle diameters 35A (1.0, 1.5, 2.0, 2.5, 3.0 mm) of the nozzle part 35.

  Table 6 shows the quality of the amount of liquid entering the inner container 20 corresponding to various nozzle diameters 35A based on the results of Tables 1 to 5, and when the nozzle diameter 35A exceeds 1.0 mm and is 1.5 mm. In addition, while reducing the amount of liquid entering the inner container 20, the outside air inhalability (air bag) to the inner container 20 for restoring the inner bag shape of the inner container 20 after refilling the outer container 10 is also good. I acknowledged that I can do it.

According to the foam production | generation container 1, there exist the following effects.
(a) The bottle holding portion 71 of the bottle holding member 70 attached to the opening 11 of the outer container 10 is inverted when the contents from the refill bottle 2 to the outer container 10 are refilled. In the state where the opening 2A of the replacement bottle 2 is loosely inserted into the opening 10A of the outer container 10, the inverted state of the refill bottle 2 is maintained.

  By simply inserting the opening 2A of the refill bottle 2 into the opening 11 of the outer container 10, the inverted state of the refill bottle 2 is maintained, and the refilling operation can be simplified.

  Since the opening 2A of the refill bottle 2 is loosely inserted into the opening 11 of the outer container 10, and the play portion becomes an air replacement passage for discharging the air in the outer container 10 to the outside, It can also be quick.

  (b) The bottle holding portion 71 of the bottle holding member 70 includes a columnar body 30B that loosely inserts the inner diameter of the opening 2A of the refill bottle 2, and the opening 2A of the refill bottle 2 is disposed on the outer periphery of the columnar body 30B. An inner diameter support portion 72A that supports and supports only a part of the inner diameter in the circumferential direction, and an end surface support portion 72B that abuts and supports only a part of the end surface of the opening 2A of the refill bottle 2. The inner diameter support part 72A of the bottle holding part 71 securely supports the refill bottle 2 in an inverted state, and the inner diameter support part 72A and the end face support part 72B of the bottle holding part 71 are loosely inserted into the bottle holding part 71. The outflow passage 3 for the contents and the air replacement passage 3 for the bottle 2 are secured between the inner diameter and end face of the opening 2A of the replacement bottle 2 and the bottle holding portion 71, so that the refilling operation can be performed easily and quickly. Can be achieved.

  (c) The above-described (a) and (b) can be realized at the time of refilling the contents from the refill bottle 2 to the outer container 10 with the container 1 in which the inner container 20 is stored in the outer container 10.

  (d) In the above (c), the joint 30 attached to the opening 11 of the outer container 10 and connected to the opening 21 of the inner container 20 is also used as the bottle holding member 70 for the refill bottle 2. it can.

  (e) In the above (d), when the joint 30 of the outer container 10 and the inner container 20 is used as the bottle holding member 70, the outer periphery of the nozzle portion 35 that forms the inner passage 34 of the joint 30 is connected to the refill bottle 2. Therefore, it can be used as a bottle holding unit 71.

  (f) The above-mentioned (e) can be realized by the foam generation container 1.

  (g) In the foam generation container 1 described in (f) above, by setting the passage diameter of the nozzle portion 35 forming the inner passage 34 of the joint 30 to more than 1.0 mm and 1.5 mm, the opening of the refill bottle 2 Even if 2A is erected and supported on the outer periphery of the nozzle part 35 that becomes the bottle holding part 71, the contents of the refill bottle 2 can be prevented from being supplied only to the outer container 10 and entering the inner container 20.

  FIG. 8 is a cross-sectional view showing a modification of the joint 30 that is the bottle holding member 70. The modification of FIG. 8 differs from the embodiment of FIG. 7 in that the opening 2A of the refill bottle 2 is eccentrically inserted into the columnar body 30B (nozzle part 35) which is the bottle holding part 71 of the joint 30. It is to have done. That is, two L-shaped rib bodies 81 are provided on one half of the outer circumference of the columnar body 30B, and each rib body 81 is disposed on the distal end side in the axial direction from the bridging portion 30C of the columnar body 30B. The small rib 81A that is provided and has a small protruding amount outward from the outer periphery of the columnar body 30B, and the small rib 81A that is provided near the bridge portion 30C of the columnar body 30B and protrudes outward from the outer periphery of the columnar body 30B. Larger ribs 81B. The small ribs 81A are L-shaped vertical pieces, and the large ribs 81B are L-shaped horizontal pieces. Further, a rectangular plate-shaped rib body 82 is provided at the same height position as the large rib 81B of the rib body 81 on the other half circumference side of the outer periphery of the columnar body 30B. A circle circumscribing the small ribs 81A of the two rib bodies 81 on one half circumference side of the columnar body 30B and the outer circumference of the other half circumference side of the columnar body 30B in a plan view of the joint 30 (FIG. 8B). The outer diameter of the circle is slightly smaller than the inner diameter of the opening 2A of the refill bottle 2, and the outer diameter of the circle circumscribing the large rib 81B of the two rib bodies 81 and the two rib bodies 82 is for refilling. The diameter is slightly larger than the outer diameter of the end face of the opening 2A of the bottle 2. Thereby, the inner side support part 72A of the bottle holding part 71 is constituted by the side surface of the small rib 81A of the rib body 81 projecting outward from the outer periphery of the columnar body 30B of the joint 30, and from the outer periphery of the columnar body 30B to the small rib 81A. The end surface support portion 72B of the bottle holding portion 71 is constituted by the large rib 81B of the rib body 81 protruding outward and the upper surface of the rib body 82.

  In addition, it is not essential that the container of the present invention is a foam generating container.
