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

  1-3 is drawing which shows Example 1 of the foamy substance ejection tube container based on this invention. 1 is a tube container of a foam-like substance ejection tube container, and the trunk | drum 1a of the tube container 1 is comprised so that pressing and an elastic restoring force are possible. A funnel-shaped foam generating device 3 is attached to the mouth portion 2 of the tube container 1. A dip tube 5 is fitted to the outer periphery of the open end 3 b of the bubble generating device 3, and the dip tube 5 constitutes an inner flow path 6. FIG. 1 is a drawing in which the first embodiment is used in an inverted state. When the body portion 1a of the tube container 1 is released from the pressed state, the rubber valve 3c is opened by the air back, and the outside air inflow passage 4 is opened. Air flows in from. When air passes through the content liquid 7, it mixes with the content liquid 7 and foams in the upper space 8 to form a foamy substance. The foamed foamed substance passes through the inner flow path 6 of the dip tube 5 and is supplied to the foam generating device 3 and poured out to the outside. In the first embodiment, a normal cap is screwed into the mouth portion 2 (not shown).

  In Example 1, since the mesh 5a was provided at the end of the dip tube 5 without providing the porous member in the foam generating device 3, conventionally, as shown in FIG. The content liquid does not enter the inner flow path 6 of the dip tube 5. And it can prevent supplying with a foam generator with aqueous solution. Therefore, at the time of ejection or re-ejection, foam-like contents are ejected from the foam generating device. Moreover, compared with the case where a porous member is provided in the foam generator, there is less resistance to pressing when the foam material is ejected. In addition, finer foams can be generated. Furthermore, by using the mesh 5a, even if the content is difficult to be foamed, it is possible to make a foam material that is more effectively foamed. The material of the mesh 5a is preferably a synthetic resin such as polyester, polyethylene, polypropylene, or nylon. The mesh opening is preferably 1 to 500 μm, more preferably 50 to 200 μm.

  Next, in Example 1, a flange 9 is formed at the tip of the bubble generating device 3. The flange 9 has a function of blocking the foamed substance poured out from the foam generating device 3 from being sucked from the outside air inflow path 4 when the tube container 1 is air-backed. This is because air bubbles in the tube container 1 are hindered when the foamy substance is sucked from the outside air inflow path 4. As shown in FIG. 1, 2 mm ≦ T ≦ 6 mm is suitable for the projecting dimension T of the flange portion 9, and 3 mm ≦ T ≦ 5 mm is more preferable.

  FIG. 3 is a second embodiment of the present invention. The second embodiment is an embodiment in which a hinge cap 10 is screwed into the mouth portion 2 of the tube container 1. A trunk cylinder 10 a of a hinge cap 10 is screwed into the mouth portion 2 of the tube container 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. 4 (a) and 4 (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, a hinge with a tension band is used in the second embodiment.

  FIG. 5 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. 5A is a view showing a state in which the lid body 16 is fitted to the trunk cylinder body 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. 5B is a diagram 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. 5C shows a state in which the elastic portion 17 is further pressed, and the head portion 18a of the engagement piece 18 slides on the slope portion of the cross-sectional triangular piece 21 of the lid body 16 to push the lid body 16 upward. 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. 4, when the lid 16 is lifted with the thumb after the lid 16 is opened to a certain angle α, the lid 16 is automatically opened by 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 the foamy substance is to be poured out from the tube container 1, the lid 16 of the hinge cap 10 is removed from the trunk cylinder 10a, the spout 14 of the trunk cylinder 10a is opened, and the tube container 1 is in an inverted state. When the portion 1a is pressed, the content foamed by the mesh 5a passes through the inner flow path 6 of the dip tube 5 in the foamed state, is sent into the foam generating device 3, and is poured out from the spout 14 to the outside. . When there is no air in the tube container 1 and the pressure is reduced, the rubber valve 3c is opened and the outside air flows into the tube container 1 through the outside air inflow path 4. As a result, outside air flows into the tube container 1, and the contents and air are mixed and foamed. And it becomes possible to press again. In addition, since the fitting of the mouth part 2 and the foam generating device 3 is firm and the outside air inflow path 4 is sealed by the rubber valve 3c, the contents leak from the mouth part 2 in a normal state. There is no. Conventionally, there has been a drawback that the content in the form of an aqueous solution is poured out from the foam generating device, but when the air or the foamy substance accumulated in the inner flow path 56 of the dip tube 55 comes into contact with the content liquid, Does not replace. Therefore, the disadvantage that the aqueous solution-like contents are extracted from the bubble generating device at the time of the first ejection and the re-ejection with the aqueous solution is eliminated.

  6 to 8 show a third embodiment of the present invention. The container according to this embodiment includes a tube container 31, a hinge cap 40, and a dip tube 35. The hinge cap 40 includes a trunk cylinder 40a and a lid 46 connected to the trunk cylinder 40a and the hinge 40b. The trunk cylinder 40 a includes an outer cylinder 41 and an inner cylinder 42 having an internal thread formed inside the outer cylinder, and the inner cylinder 42 is screwed into the mouth portion 32 of the tube container 31. The inner cylinder 42 has a top wall 43 provided with a spout 44a and an outside air inflow cylinder 44b on its top surface. Unlike the first embodiment, the spout 44a and the outside air inflow cylinder 44b are not provided concentrically. Further, the spout 44a is formed such that its upper end is higher than the upper end of the outside air inflow cylinder 44b, and its position is formed closer to the outer periphery of the main cylinder 40a (outer cylinder 41) than the position of the outside air inflow cylinder 44b. Has been. On the other hand, similarly to the second embodiment (FIGS. 3 to 5), the outer cylinder 41 can be provided with a mechanism for opening the lid 46 with one touch. The lid body 46 includes fitting cylinders 45a and 45b that seal the spout 44a and the outside air inflow cylinder 44b in the closed state.

  In the hinge cap 40 thus configured, the dip tube 35 constituting the inner flow path 36 is connected to the back surface of the top wall 43 and communicates with the spout 44a. At the lower end of the dip tube 35, a mesh 35a similar to that of the first embodiment is provided. A spherical valve 44c is preferably inserted into the outside air inflow cylinder 44b. As will be described later, the spherical valve 44c is movable between an upper valve seat 44d having a narrow opening and a lower valve seat 44e constituted by a plurality of protrusions. With this configuration, the total number of parts can be reduced, and the manufacturing cost can be further reduced by the spherical valve 44c that is cheaper than the rubber valve 3c of the first embodiment.

  Next, a method for extracting the foamy substance from the tube container 31 will be described. First, the lid 46 of the hinge cap 40 is opened as in the second embodiment (FIG. 5), and the spout 44a and the outside air inflow tube 44b are opened. Then, the tube container 31 is turned upside down as shown in FIG. Then, the content finely foamed by the mesh 35a is poured out from the spout 44a through the inner flow path 36 of the dip tube 35, as indicated by an arrow. At this time, it is possible to effectively prevent the aqueous content from being poured out. On the other hand, since the outside air inflow cylinder 44b is closed by the spherical valve 44c that is in contact with the upper valve seat 44d, the content liquid 37 does not leak from the outside air inflow cylinder 44b.

  Then, when the pressing of the body portion 31a is stopped, an air bag phenomenon occurs as shown in FIG. That is, when the spherical valve 44c that has been in contact with the upper valve seat 44d moves toward the lower valve seat 44e, the outside air flows into the tube container 31 through the outside air inflow cylinder 44b as indicated by an arrow. Due to this air bag phenomenon, the body portion 31a of the tube container 31 is restored, and the content liquid 37 in the tube container 31 is mixed with air to form a foamy substance in the upper space 38 of the container. And the trunk | drum 31a of the tube container 31 can be pressed again.

  On the other hand, when the air bag phenomenon occurs, a force for drawing the foamed substance after the pouring into the outside air inflow cylinder 44b acts. If the foamy substance adheres to the outside air inflow cylinder 44b and is dried or solidified later, the outside air may not be allowed to flow into the tube container 31. However, in this embodiment, since the upper end of the spout 44a is formed higher than the outside air inflow cylinder 44b, and these are not provided concentrically, such a problem can be prevented.

  Moreover, 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 containers 1 and 31. When carrying as a portable tube in a bag, the length dimensions of the tube containers 1 and 31 are 59 mm ≦ A ≦ 182 mm, preferably 72 mm ≦ A ≦ 164 mm. The outer diameter dimensions of the body portions 1a and 31a of the tube containers 1 and 31 are 19 mm ≦ B ≦ 40 mm, preferably 25 mm ≦ B ≦ 35 mm. Of course, by increasing the length and outer diameter of the tube containers 1 and 31, they can be used for general household use and general business use.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to these embodiment. For example, in the above-described embodiment, the meshes 5a and 35a are directly provided at the ends of the dip tubes 5 and 35, but one or more meshes are provided on a separately prepared member, for example, a cylindrical member, This member may be fitted to the end of the dip tube (not shown). Moreover, it is not limited to the meshes 5a and 35a, and may be a porous member such as a foamed body such as a synthetic resin, a sintered body, or a nonwoven fabric, or may be a combination of these porous member and mesh. (Not shown). Furthermore, in the embodiment of the present invention, the tube containers 1 and 31 have been described as examples. However, the same effect as in the present invention can be obtained when a bottle container having an elastic restoring force is used instead of the tube container. Can be obtained (not shown).

  The foam material 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 and hand soap, foods, etc. Since a foam-like substance can be poured out, it can be widely used as a foam-like 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.
