  Hereinafter, the bubble ejection tube container of the present invention will be described in detail with reference to the drawings.

  In FIG. 1, the code | symbol 1 is the foam ejection tube container 1 which is one Embodiment of this invention, and the code | symbol 2 is a synthetic resin container main body which has flexibility. The container body 2 is formed in a tube shape having a mouth tube portion 2a and heat-sealed at the rear end 2b. The body portion 2c is deformed by squeezing (squeezing) the user, while being restored by releasing the squeeze. A filling space S0 filled with the content liquid M is formed inside the container body 2.

  Reference numeral 10 denotes a foam ejection cap fixed to the container body 2. The foam ejection cap 10 includes a plug body 10a attached to the mouth tube portion 2a, an intermediate member 10b fixed to the plug body 10a, and a nozzle 10c fixed to the intermediate member 10b. In the present embodiment, the bubble ejection cap 10 is provided with a removable overcap 10d.

  As shown in FIG. 2, the plug 10a has a partition wall 11 that closes the mouth tube portion 2a. The partition wall 11 has a mounting portion 12 surrounding the mouth tube portion 2a. For example, as shown in the drawing, the mounting portion 12 has a screw portion, and is detachably screwed into a screw portion formed in the mouth tube portion 2a. Thereby, the plug 10a is attached to the mouth tube portion 2a. A suction cylinder 13 is provided integrally with the partition wall 11. A suction pipe P with a filter f attached to the end is fixed to the suction cylinder 13. Inside the suction pipe P, a passage r1 leading to the filling space S0 through the filter f is formed. In addition, a passage r2 leading to the filling space S0 is formed between the suction pipe 13 and the suction pipe P. The passage r2 can be formed in at least one place around the axis O. For example, the passage r <b> 2 can be formed between the suction pipe P by forming a longitudinal groove inside the suction cylinder 13 as in the present embodiment. However, according to the present invention, the passage r2 can be configured by a separately provided through hole or the like. Further, inside the suction cylinder 13, a mixing path r <b> 3 is formed in which the passage r <b> 1 and the passage r <b> 2 merge to mix the content liquid M in the container body 2 and the air Air. In addition, the partition wall 11 is formed with an annular recess 11a around the suction cylinder 13, and a through-hole A2 that leads to the filling space S0 is formed in the recess 11a. The through hole A2 can also be formed in at least one place around the axis O.

  The intermediate member 10b has a peripheral wall 14 that goes around the axis O. One end of the peripheral wall 14 is fixed to the plug 10a via the fixing portion C1, and the other end is fixed to the nozzle 10c via the fixing portion C2. As the fixing portion C1, for example, as shown in the drawing, a so-called undercut fitting in which convex portions provided to each other are fitted is exemplified. In addition, as shown in the figure, for example, press fitting may be used for the fixing portion C2. However, the fixing portions C1 and C2 are not limited to the illustrated ones, and various fixing means can be employed. In addition, a seal portion S is provided between the stopper 10a and the intermediate member 10b inside the fixed portion C1. The seal portion S is composed of an annular seal tube portion 11s that stands up from the plug 10a and an annular seal tube portion 14s that hangs down from the intermediate member 10b.

  A partition wall 15 is integrally provided inside the peripheral wall 14. The partition wall 15 divides the space formed between the plug body 10a and the nozzle 10c into two spaces, a space S1 on the nozzle side and a space S2 on the container body side. Further, the cylindrical body portion 16 stands integrally with the partition wall 15 from the partition wall 15 toward the nozzle-side space S1. An annular gap G is formed in the nozzle-side space S <b> 1 by raising the cylindrical portion 16 from the partition wall 15. Furthermore, the partition wall 15 is formed with a through hole A1 that allows the gap G to communicate with the space S2 on the container body side. The through hole A1 is configured as a long hole extending along the axis O as shown in FIG. The through hole A1 can be formed in at least one place around the axis O.

  As shown in FIG. 2, two foam generating members 17 are arranged inside the cylindrical body portion 16. The foam generating member 17 generates the mixture in the form of foam through the mixture of the content liquid M and the air Air that are pumped by deformation of the container body 2. In this embodiment, the foam generating member 17 is configured by a mesh ring. The mesh ring is formed by attaching a mesh member 17b to one end of the ring body 17a. In addition, the foam production | generation member 17 can be comprised by at least one. In the partition wall 15, an opening A 0 that communicates with the foam generating member 17 is formed inside the cylindrical body portion 16. In the present embodiment, a passage r5 is formed between the opening A0 and the foam generating member 17.

  On the other hand, the composite valve 20 is disposed in the space S2 on the container body side. The composite valve 20 has a cylindrical member 21. Inside the cylindrical member 21, a passage r4 is formed that connects the mixing path r3 formed in the plug body 10a to the opening A0 formed in the intermediate member 10b. One end of the cylindrical member 21 is fixed to the plug 10a via the fixing portion C3, and the other end is fixed to the intermediate member 10b via the fixing portion C4. The fixing portions C3 and C4 include, for example, press fitting as illustrated. However, the fixing portions C3 and C4 are not limited to those shown in the drawing, and various fixing means can be adopted as long as the sealing property is ensured.

  An intake valve 22 is integrally provided outside the cylindrical member 21. The intake valve 22 is configured as an annular diaphragm that integrally expands from the outer peripheral surface of the cylindrical member 21. In the normal state, the intake valve 22 seals the through hole A1 as shown in FIG. 2, and opens the through hole A1 by the negative pressure generated in the space S2 on the container body side. A discharge valve 23 is integrally provided inside the cylindrical member 21. The discharge valve 23 is connected to the tubular member 21 via a plurality of connecting pieces 24 that integrally extend from the inner peripheral surface of the tubular member 21. The discharge valve 23 normally seals the opening of the mixing path r3 and opens the opening of the mixing path r3 by the pumping force generated in the mixing path r3.

  Here, an example of the usage method of the bubble ejection tube container 1 is demonstrated.

  In an example of this embodiment, first, when the foam ejection tube container 1 is turned upside down from the state shown in FIG. 1 and the foam ejection cap 10 is turned downward as shown in FIG. M and air Air are divided into a liquid layer (M) and an air layer (Air) as shown in FIG. At this time, the suction pipe P is exposed from the liquid level of the content liquid M and allows the passage r1 to communicate with the air layer (Air), while the passage r2 communicates with the liquid layer (M). For this reason, as shown in the figure, when the container body 2 is crushed and deformed, the pressure in the filling space S0 increases, so that the air and the content liquid M in the filling space S0 respectively pass from the filter f. It is introduced into the mixing path r3 through r1 and introduced into the mixing path r3 through the passage r2. In addition, since the mixture of the content liquid M and air Air is pumped into the mixing path r3, the discharge valve 23 that closes the mixing path r3 is opened by the pumping force, so that the mixture passes through the passage of the cylindrical member 21. From r4 and r5, it is ejected in the form of bubbles from the ejection port 18 through the foam generating member 17. At this time, since no negative pressure is generated in the space S2 on the container body side, the intake valve 22 prevents the introduction of outside air from the jet port 18 while the through hole A1 is closed as shown in FIG. Thereby, the foam-like mixture according to the deformation | transformation of the container main body 2 can be ejected.

  On the other hand, as shown in FIG. 5, when the deformation of the container body 2 is released and restored, the pressure in the filling space S <b> 0 decreases and negative pressure is generated, so the discharge valve 23 closes the mixing path r <b> 3. In the intake valve 22 disposed in the space S2 on the container body side, the negative pressure is generated in the space S2 together with the filling space S0 through the through hole A2, thereby opening the through hole A1. Outside air from the jet port 18 is introduced into the container body 2 (filling space S0). At this time, since the annular gap G leading to the ejection port 18 is formed in the nozzle-side space S1, the nozzle-side space S1 is compared with the case where a through-hole is simply formed in the partition wall 15. The remaining foam (liquid) can be more efficiently guided from the through hole A1 formed in the intermediate member to the space S2 on the container body side. As a result, the bubble (liquid) breakage after the foam ejection is improved efficiently, so that it can be used cleanly for a long period of time, and the container body 2 can be restored smoothly and the operability is also good. It becomes.

  Therefore, according to the present embodiment, it is possible to provide a novel bubble ejection cap 10 that has good bubble operability and good operability, and a bubble ejection tube container 1 including the same. In the present embodiment, as shown in FIGS. 1 and 2, the same method can be used even when the foam ejection cap 10 is facing upward. However, in this case, the contents liquid M and air Air in the filling space S0 are respectively introduced from the filter f through the passage r1 into the mixing passage r3 and introduced into the mixing passage r3 through the passage r2, contrary to the above description. The

  The above description shows only one embodiment of the present invention, and various modifications can be made according to the present invention. For example, the intake valve 22 and the discharge valve 23 can be configured as separate bodies without being provided integrally with the cylindrical member 21. Further, the foam ejection cap 10 is not limited to the one that is attached to the mouth tube portion 2a by screwing. For example, the plug body 10a can be plugged by undercut fitting or the like. . Furthermore, the filter f provided in the suction pipe P can be omitted.

  INDUSTRIAL APPLICABILITY The present invention can be applied as a foam ejection cap capable of ejecting contents in a foam shape by deformation and restoration of the container body, and a foam ejection tube container including the same. Examples of the contents include various liquid detergents such as shampoos, body soaps, hand soaps, and facial cleansers, and hair conditioners such as set lotions.
