  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

  1-4 is drawing which shows Example 1 of the foamy substance ejection tube container based on this invention. Reference numeral 1 denotes a tube container main body of a foam-like substance ejection tube container, and a body portion 1a of the tube container main body 1 is configured to be capable of pressing and elastic restoring force. A funnel-shaped foam generating device 3 is attached to the mouth 2 of the tube container main body 1. In this foam generating device 3, a porous member 3a such as urethane foam or sponge is fitted, and the open end 3b of the foam generating device 3 is connected so that the porous member 3a communicates with the inside of the tube container body 1. The outer flow path 4 is formed. Further, a dip tube 5 is fitted to the inner peripheral surface of the opening end 3 b of the bubble generating device 3, and this dip tube 5 constitutes an inner flow path 6. That is, the outer flow path 4 and the inner flow path 6 are provided separately. Further, a rubber valve 7 for controlling the inflow of air is attached to the bottom of the foam generating device 3, and after the foam-like substance is poured out, the outside air passes through the outside air inflow passage 8 and is the tube container body. 1 is flowed into.

  On the other hand, a trunk cylinder 10 a of a hinge cap 10 is screwed into the mouth 2 of the tube container body 1. The hinge cap 10 is formed on the inner side of the trunk cylinder 10 a, and has an inner cylinder 12 having an internal thread, a top wall 13 formed on the top surface of the inner cylinder 12, and a spout 14 formed on the top wall 13. And a lid 16 having a fitting cylinder 15 fitted to the spout 14 so as to be opened and closed. As shown in FIGS. 2 (a) and 2 (b), a bullet piece portion 17 is formed on the front surface of the trunk cylinder 10a, and an engagement piece 18 is formed continuously with the bullet piece portion 17. Has been. On the other hand, the lid body 16 is formed with an engagement piece 19 that is detachably engaged with the engagement piece 18 and a triangular cross-section piece 21 for opening the lid body 16 by a certain angle α, and one end is formed by a hinge 10b. It is connected to the trunk cylinder 10a. As the hinge 10b, the hinge 10b with a tension band is used in the first embodiment. Instead of the hinge cap 10, a normal cap (not shown) may be screwed into the mouth portion 2 of the tube container body 1.

  5 and 6 are drawings showing Example 2 of the foamed substance ejection tube container according to the present invention. The difference from the first embodiment is that the dip tube 35 is fitted to the outer peripheral surface of the opening 33b without being fitted to the inner peripheral surface of the opening end 33b. Therefore, the outer flow path is not formed as in the first embodiment. Therefore, in the second embodiment, when the tube container main body 31 is in the upright state, the dip tube 35 is inverted because the air in the tube container main body 30 does not have a structure or function for supplying the air from the outer flow path into the foam generating device. Can only be used in the state. FIG. 6 is a diagram in which the second embodiment is used in an inverted state. When the body portion of the tube container body 31 is released from the pressed state, air flows in from the outside air inflow passage 38 by air back. When air passes through the inner solution 30, it mixes with the inner solution 30 and foams in the upper space 39 to form a foamy substance. The foamed foam material passes through the inner flow path 36 of the dip tube 35 and is supplied to the foam generating device 33. And it foams further largely with the mesh 33c provided in the foam generation apparatus 33, and is poured out outside. FIG. 6 is a view showing a case where the hinge cap 10 is used without being screwed into the mouth portion 32. In this case, a normal cap may be screwed into the mouth portion 32 (not shown). Further, as shown in FIG. 5, the hinge cap 10 may be screwed into the mouth portion 32 of the tube container main body 31 in the same manner as in the first embodiment.

  In Example 2, since the mesh 33c is provided without providing the porous member in the foam generating device 33, when the foam-like substance is poured out, there is little resistance when pressed. In addition, finer foams can be generated. Furthermore, by using a mesh, even if the content is difficult to be foamed, it is possible to more effectively create a foam material that is greatly foamed. The material of the mesh 33c is preferably a synthetic resin such as polyester, polyethylene, polypropylene, or nylon. The mesh opening is preferably 1 to 500 μm, more preferably 100 to 200 μm. In the second embodiment, a flange 34 is formed at the tip of the foam generating device 33. The flange 34 has a function of blocking the foamed substance poured out from the foam generating device 33 from being sucked from the outside air inflow passage 38 when the tube container 31 is air-backed. This is because when the foamy substance is sucked from the outside air inflow passage 38, the air bag of the tube container 31 is hindered. As shown in FIG. 6, the projecting dimension S of the flange portion 34 is preferably 2 mm ≦ S ≦ 6 mm, and more preferably 3 mm ≦ S ≦ 5 mm.

  FIG. 7 is a view showing a state in which the lid 16 of the hinge cap 10 is opened by a certain angle α by the operation of the trunk cylinder 10a. Fig.7 (a) is drawing which shows the state which the cover body 16 has fitted to the trunk cylinder 10a. That is, the head 18a of the engagement piece 18 of the trunk cylinder 10a and the head 19a of the engagement piece 19 of the lid 16 are engaged. FIG. 7B is a view showing a state in which the elastic portion 17 is slightly pressed to disengage the head 18 a of the engagement piece 18 and the head 19 a of the engagement piece 19. 7C shows a state in which the elastic portion 17 is further pressed, and the head portion 19a of the engagement piece 19 pushes the lid body 16 upward by sliding on the slope portion of the cross-sectional triangular piece 21 of the lid body 16. FIG. Thereby, the spout 14 and the fitting cylinder 15 are disengaged, the spout 14 is opened, and the foamy substance can be poured out. As shown in FIG. 2, when the lid 16 is lifted with a thumb after the lid 16 is opened to a certain angle α, the lid 16 automatically opens 120 degrees or more by the action of the hinge 10 b with the tension band. That is, it can be opened by a one-touch operation. When closing the lid body 16, when the lid body 16 is pressed by hand, the head portion 18a of the engagement piece 18 and the head portion 19a of the engagement piece 19 of the lid body 16 are engaged with each other with a click feeling. At the same time that the body 16 engages with the trunk cylinder 10a, the spout 14 and the fitting cylinder 15 are fitted, and the spout 14 is closed.

  When pouring the foamy substance from the tube container body 1, as shown in FIG. 3, the lid 16 of the hinge cap 10 is removed from the basic cylinder 10a, and the spout 14 of the basic cylinder 10a is opened. When the body portion 1 a of the tube container body 1 is pressed, the content liquid 20 in the tube container 1 passes through the inner flow path 6 of the dip tube 5 and is sent into the porous member 3 a of the foam generating device 3. On the other hand, the air passes through the outer flow path 4 of the opening end 3 b of the foam generating device 3 and is similarly sent into the porous member 3 a of the foam generating device 3. In the porous member 3 a, the air and the content liquid 20 are mixed and foamed and poured out from the spout 14. As shown in FIG. 4, when the foamed material is to be poured out with the hinge cap 10 removed in an inverted state, the tube container body 1 is inverted and the body portion 1a is pressed. The air passes through the inner flow path 6 of the dip tube 5 and is sent into the porous member 3 a of the foam generating device 3, while the content liquid 20 passes through the outer flow path 6 of the open end 3 b of the foam generating device 3. Then, it is similarly sent into the porous member 3a of the foam generating device 3. Similarly, the air and the content liquid 20 are mixed and foamed in the porous member 3a. When there is no air in the tube container body 1 and the pressure is reduced, the rubber valve 7 is lowered downward, so that the outside air flows into the tube container body 1 through the external airway 8. As a result, outside air flows into the tube container body 1 and can be pressed again. In addition, since the fitting between the mouth portion 2 and the foam generating device 3 is firm and the outside air inflow path 8 is sealed by the rubber valve 7, the content 20 leaks from the mouth portion 2 in a normal state. There is no.

  The foam material ejection tube container according to the present invention can be carried in a bag or the like by reducing the volume of the tube container body 1. When the portable tube is carried in a bag, the length A (see FIG. 4) of the tube container body 1 is 59 mm ≦ A ≦ 182 mm, preferably 72 mm ≦ A ≦ 164 mm. The outer diameter B (see FIG. 4) of the body portion 1a of the tube container body 1 is 19 mm ≦ B ≦ 40 mm, preferably 25 mm ≦ B ≦ 35 mm. Of course, by increasing the length and outer diameter of the tube container body 1, it can be used for general household use and general business use.

  The foamed substance ejection tube container according to the present invention is filled with a medicine such as a disinfectant, cosmetics such as hair cream, beauty care products such as shaving cream, hand soap, etc. It can be widely used as a substance ejection tube container. In particular, by reducing the size of the tube container, it is convenient to carry it in a bag or the like for portable use. Further, it may be used in ordinary households, companies, etc., and may be always placed in a washroom of ordinary households, companies, etc.
