  On the other hand, in the conventional foam discharge container as described above, the amount of the foam-like content liquid discharged by one push operation to the pump head is small, so the user wants to use a large amount of the foam-like content liquid. In some cases, it is necessary to repeat the pushing operation a plurality of times to take out a desired amount of the content liquid.

  On the other hand, in recent years, various forms of use have been demanded for foam discharge containers, and as much foam-like content liquid as possible can be discharged by a single pushing operation to the pump head. It is being considered to do so.

  By increasing the volume of the air chamber and the liquid chamber in the cylinder part of the foam discharger, it becomes possible to discharge a large amount of content liquid in the form of foam by a single pushing operation, but in the conventional foam discharge container, When the volume of the air chamber is increased, for example, at least part of the air chamber of the cylinder portion is disposed inside the mouth portion via a base cap portion attached to the mouth portion of the container body. The diameter of the neck becomes excessive, and the size of the container body and the amount of resin increase. Further, when the container is used while being gripped, if the container body is too large, it is difficult to grip and the handling becomes inconvenient.

  Even when the volume of the air chamber of the cylinder portion is increased, the present invention can suppress the size of the container body and the amount of resin so that the diameter of the neck portion does not become excessive, and improves the ease of handling when gripping. It aims at providing the foam discharge container which can be made.

The present invention comprises a container main body for storing the content liquid and a foam discharger attached to the mouth of the container main body, and the foam discharger includes a reciprocating piston head connected to the piston part. The piston head is pushed into the first flow path for sending the content liquid from the small diameter liquid introduction chamber of the pressurized cylinder section to the mixing chamber, and from the large diameter air chamber of the pressurized cylinder section. The second flow path for sending air to the mixing chamber is opened, and the content liquid and the air sent to the mixing chamber are mixed, foamed, and discharged in a foaming flow path from the mixing chamber to the discharge port. A foam discharge container, wherein the piston portion includes a cylindrical piston member that passes through a central portion of the air chamber of the cylinder portion and whose lower end portion slides along an inner peripheral surface of the liquid introduction chamber, and the cylinder That protrudes radially outward from the piston member An air piston member that slides along the inner circumferential surface of the air chamber, and the foam discharger has a bottom peripheral portion of the air chamber above the mouth portion of the container body. The air chamber is disposed integrally with the mouth portion in a state where the outer circumferential surface of the air chamber is disposed above the outer circumference surface of the mouth portion and the air chamber is provided outside the mouth portion. A male threaded portion is formed on the outer peripheral surface of the lower portion of the air chamber, and the female threaded portion engages with both the male threaded portion of the air chamber and the male threaded portion formed on the outer peripheral surface of the mouth neck. The above object is achieved by providing a foam discharge container in which the foam discharger is integrally attached to the neck part through a joining sleeve member having a threaded part formed on the inner peripheral surface .

  According to the foam discharge container of the present invention, even when the volume of the air chamber of the cylinder portion is increased, the size of the container main body and the amount of resin can be suppressed and the gripping can be performed while the diameter of the neck portion is not excessive. The ease of handling can be improved.

It is a longitudinal cross-sectional view explaining the structure of the foam discharge container which concerns on preferable one Embodiment of this invention. It is explanatory drawing of the hair cosmetic kit using the foam discharge container which concerns on preferable one Embodiment of this invention.

  A foam discharge container 10 according to a preferred embodiment of the present invention shown in FIG. 1 is a so-called pump former container, and the foam mounted on the mouth part 12 of the container body 11 is the same as a conventional pump former container. It has a function of discharging the content liquid into a foam by mixing it with air by pushing the discharge head (pump former) 13 into the piston head (pump head) 14. Moreover, the foam discharge container 10 of this embodiment is used by foaming and using the liquid mixture which mixed the 1st agent containing an alkaline agent and the 2nd agent containing hydrogen peroxide, as shown in FIG. It is used as a component of a kit for hair coloring or hair bleaching.

  That is, the kit for hair coloring or hair bleaching includes a first container 30 in which a first agent is stored, a second container 31 in which a second agent is stored, and a foam dispenser 13 that is a pump former. And the joining sleeve member 26 having an internal thread portion formed on the inner peripheral surface, and the container body of the second container 31 also serves as the container body 11 of the foam discharge container 10 of the present embodiment. It is like that.

  And when performing hair dyeing or decoloring using a kit for hair coloring or hair bleaching, the lid 30a of the first container 30 is removed and the lid 31a of the second container 31 is removed. The first agent stored in the first container 30 is poured into the container body 11 of the second container 31 in which the second agent is stored. Moreover, the foam discharge container 10 of this embodiment is formed as shown in FIG. 1 by attaching the foam discharger 13 to the mouth neck portion 12 of the container main body 11 via the joining sleeve member 26. After that, the formed foam discharge container 10 is gripped and shaken lightly from side to side, for example, to shake the test tube, vigorously shaken up and down, or changed from the substantially upright state to the inverted or sideways state, and again in the substantially upright state. The mixing of the first agent and the second agent is promoted inside the container body 11 by, for example, a method of repeating the operation of returning to. When the first agent and the second agent are sufficiently mixed to form a mixed liquid, the piston of the foam discharger 13 is held in a state where the foam discharge container 10 is held or the foam discharge container 10 is left in place. By performing an operation of pushing the head 14, the liquid mixture for hair coloring or hair decoloration, which is the content liquid, is foamed and discharged in a predetermined amount.

  Here, in order to perform hair dyeing or decolorization by foaming and discharging the liquid mixture for hair dyeing or hair bleaching, a large amount of mixing is performed by a single pushing operation rather than a conventional pump former container. It is preferable to discharge the liquid. In order to discharge a large amount of liquid mixture in a foam state by a single pushing operation, it is necessary to increase the capacity of the air chamber 18 of the cylinder portion 16 in which the air sent to the mixing chamber 19 is stocked. When the volume of the air chamber is increased, the diameter of the neck portion where the air chamber is suspended and the size of the container main body become excessive, so that the amount of resin increases and it becomes difficult to grip the container. It becomes difficult to perform an operation for mixing the agent and an operation for pushing the piston head. The foam discharge container 10 of the present embodiment suppresses the amount of resin by a simple configuration so that the diameter of the neck 12 and the size of the container body 11 do not become excessive even when the capacity of the air chamber 18 is increased. In addition, a function of facilitating gripping the container 10 is provided.

  As shown in FIG. 1, the foam discharge container 10 of the present embodiment includes a container main body 11 that stores the content liquid, and a foam discharger 13 that is attached to the mouth portion 12 of the container main body 11. The piston head 14 connected to the piston portion 15 is reciprocally movable. When the piston head 14 is pushed in, the content liquid (from the small-diameter liquid introduction chamber 17 of the pressurized cylinder portion 16 is transferred to the mixing chamber 19. A first flow path 20 for sending a liquid mixture of the first and second agents) and a second flow path 21 for sending air from the large-diameter air chamber 18 of the pressurized cylinder portion 16 to the mixing chamber 19. The contents liquid (mixed liquid of the first agent and the second agent) sent to the mixing chamber 19 and the air are mixed and foamed in the foaming flow path 23 extending from the mixing chamber 19 to the discharge port 14c and discharged. It is a container.

  Further, in the foam discharge container 10 according to the present embodiment, the piston portion 15 penetrates the central portion of the air chamber 18 of the cylinder portion 16 and the lower end portion slides along the inner peripheral surface of the liquid introduction chamber 17. The bubble ejector 13 includes a member 24 and an air piston member 25 that projects from the cylindrical piston member 24 radially outward and slides along the inner peripheral surface of the air chamber 18. Is arranged such that the bottom peripheral edge portion 18a of the air chamber 18 is disposed above the neck portion 12 of the container body 11, and the outer peripheral surface 18b of the air chamber 18 is disposed above the outer peripheral surface 12b of the mouth portion 12, so that the air The entire chamber 18 is attached to the upper part of the mouth part 12 in a state of being provided outside the mouth part 12.

  Further, in the present embodiment, a male screw portion 18 c is formed on the outer peripheral surface 18 b at the lower part of the air chamber 18, and the male screw portion 18 c of the air chamber 18 and the male screw portion 18 b formed on the outer peripheral surface 12 b of the mouth portion 12. The foam discharger 13 is integrally mounted on the mouth neck portion 12 through a joining sleeve member 26 in which a female screw portion 26c screwed to both the screw portion 12c is formed on the inner peripheral surface.

  In the present embodiment, the container body 11 is a bottle-shaped plastic molded product, for example, a bottomed cylindrical body portion 11a and a reduced diameter in a tapered surface shape upward from the upper end portion of the body portion 11a. The shoulder portion 11b is provided, and the mouth portion 12 is provided so as to protrude in a cylindrical shape upward from the upper end portion of the shoulder portion 11b. The trunk | drum 11a has an outer diameter of about 40-80 mm as an outer diameter which is easy to hold | grip with a hand, for example. The mouth part 12 has an outer diameter smaller than the outer diameter of the body part 11a, for example, about 25 to 65 mm, and a male screw part for attaching the foam discharger 13 to the outer peripheral surface 12b of the mouth part 12. 12c is provided.

  The bubble discharger 13 is a single unit in which a cylindrical piston member 24 that sucks, pressurizes, and discharges a liquid and an air piston member 25 that sucks, pressurizes, and discharges air are arranged in a concentric series. A pump device 27 including one cylinder portion 16 is included. The pump device 27 includes a cylinder portion 16 composed of a large-diameter air chamber 18 disposed at an upper portion, and a small-diameter liquid introduction chamber 17 continuously extending downward from a central portion of the bottom of the air chamber 18, and a liquid A cylindrical piston member 24 that slides along the inner peripheral surface of the introduction chamber 17, and an air that protrudes radially outward from the cylindrical piston member 24 and slides along the inner peripheral surface of the air chamber 18. A piston portion 15 including a piston member 25;

  Further, the pump device 27 is provided with a top surface base portion 28 covering the upper portion of the substantially bottomed cylindrical air chamber 18, and protrudes upward from the center portion of the top surface of the top surface base portion 28 to form a cylindrical shape. The guide stem 29 is erected. The hollow pipe portion 14a of the piston head 14 is slidably inserted into the guide stem 29, so that the piston head 14 has its head main body portion 14b disposed above the pump device 27 and the top surface base. The part 28 is provided so as to be able to reciprocate up and down. The piston head 14 is configured such that the upper end portion of the cylindrical piston member 24 of the pump device 27 is fitted and connected to the lower end portion of the hollow pipe portion 14a, so that the liquid in the cylinder portion 16 is interposed therebetween. The spring member 32 provided in the introduction chamber 17 is biased upward by the action.

  In this embodiment, by pushing down the piston head 14 against the urging force of the spring member 32, the cylindrical piston member 24 and the air piston member 25 of the pump device 27 are also pushed down simultaneously, and the ball valve 20a is moved upward. It moves and the 1st flow path 20 is open | released. As a result, the content liquid is pressurized and discharged from the liquid chamber 33 inside the cylindrical piston member 24 communicating with the liquid introduction chamber 17 toward the foaming flow path 23 in the hollow pipe 14a. Further, the second flow path 21 as the air flow path formed along the joint portion between the cylindrical piston member 24 and the air piston member 25 and the fitting portion between the hollow pipe 14a and the cylindrical piston member 25 is closed. The air in the air chamber 18 is pressurized and discharged toward the foaming flow path 23 in the hollow pipe 14a so that it can be circulated by opening 34. After the content liquid and the air discharged toward the foaming flow path 23 are mixed in the mixing chamber 19 as a merge space and foamed by passing through the foam generating member 22 provided on the downstream side of the mixing chamber 19. The liquid is discharged from the discharge port 14c of the piston head 14 in the form of foam.

  On the other hand, when the pressing of the piston head 14 is released, the piston head 14 is pushed upward by the biasing force of the spring member 32, the cylindrical piston member 24 and the air piston member 25 are also pushed up simultaneously, and the ball valve 20a is lowered downward. By moving, the first flow path 20 is closed, and the discharge of the content liquid is blocked. Since the liquid chamber 33 inside the cylindrical piston member 24 becomes negative pressure due to the blockage of the ball valve 20a, the introduction passage is opened by moving the poppet valve 35 upward, and the content liquid in the container main body 11 is opened. Is sucked into the liquid chamber 33 through the suction pipe 36 and the liquid introduction chamber 17. Further, as the air piston member 25 rises, the air chamber 18 becomes negative pressure and generates a suction force. With this suction force, the check valve 37 provided in the air piston member 25 is opened, and the outside air is taken into the air chamber 24 via the gap between the guide stem 29 and the hollow pipe portion 14a of the piston head 14. Furthermore, the closing part 34 is closed by the rise of the piston head 14 and the accompanying rise of the cylindrical piston member 24 and the air piston member 25, and the flow of air through the second flow path 21 is blocked. In addition, the obstruction | occlusion part 34 is equipped with the structure similar to the obstruction | occlusion part of the foam dispenser as described in Japanese Patent Application No. 2009-78149 which concerns on this application.

  And in this embodiment, the foam discharger 13 arrange | positions the bottom part peripheral part 18a of the air chamber 18 of the pump apparatus 27 above the neck part 12 of the container main body 11, and sets the outer peripheral surface 18b of the air chamber 18 to a mouth part. 12 is disposed above the outer peripheral surface 12b, and is integrally attached to the upper portion of the mouth portion 12 in a state where the entire air chamber 18 is provided outside the mouth portion 12.

  In other words, in the present embodiment, the air chamber 18 has a substantially bottomed cylindrical shape in which the liquid introduction chamber 28 extends downward from the bottom center portion, and the outer diameter thereof is the same as the outer diameter of the mouth portion 12. For example, the outer diameter is about 20 to 80 mm. A male threaded portion 18 c is formed on the outer peripheral surface 18 b at the lower part of the air chamber 18. Therefore, after the lower half portion of the joining sleeve member 26 having the inner diameter similar to these outer diameters and having the female thread portion 26c formed on the inner peripheral surface of the container body 11 is screwed and attached, By screwing and attaching the lower portion of the air chamber 18 to the upper half portion of the sleeve member 26, the foam discharger 13 has the lower end of the outer peripheral surface 18b of the air chamber 18, that is, the bottom peripheral edge portion 18a of the air chamber 18 is the neck portion 12. It arrange | positions so that the upper edge of may be touched. In this way, the foam discharger 13 is joined to the joining sleeve member 26 in a state where the outer peripheral surface 18b of the air chamber 18 is disposed above the outer peripheral surface 12b of the neck part 12 and the entire air chamber 18 is provided outside the mouth part 12. It is fixed to the mouth part 12 of the container body 11 as a unit.

  Here, in the present embodiment, the air chamber 18 has a height from the bottom portion to the top surface base portion 28 of, for example, about 35 to 50 mm, and has a large volume of, for example, about 20 to 80 cc. . Thereby, as compared with the conventional pump former, a larger volume of air can be sent to the mixing chamber 19 or a larger volume of air can be stored by a single pushing operation of the piston head 14. It is like that.

  And according to the foam discharge container 10 of this embodiment which has the above-mentioned structure, even when the volume of the air chamber 18 of the cylinder part 16 is increased, the diameter of the neck part 12 does not become excessive, and the container main body 11 The size and the amount of resin can be suppressed, and the ease of handling when the container 10 is gripped can be improved.

  That is, according to this embodiment, the foam discharger 13 arranges the bottom peripheral edge portion 18a of the air chamber 18 above the neck portion 12 of the container body 11, and the outer peripheral surface 18b of the air chamber 18 to the mouth portion 12. Since the air chamber 18 is disposed integrally with the mouth portion 12 with the air chamber 18 provided on the outside of the mouth portion 12 so as to be disposed above the outer peripheral surface 12b, the base is provided like a conventional pump former container. It is not necessary to arrange the air chamber in a state of being hung inside the mouth part through the cap part. Accordingly, even when the outer diameter of the air chamber 18 is increased to increase the volume, it is not necessary to increase the inner diameter of the mouth portion 12, so that the size of the container body 11 and the amount of resin can be effectively suppressed. Become. It is also possible to design the container body 11 with a small size.

  In addition, since the mouth portion 12 and the container body 11 can be formed into a slim shape that can be easily gripped, the container 10 can be handled easily, for example, lightly shaken to the left and right like shaking a test tube, or shaken vigorously up and down. Or when the first agent and the second agent are mixed inside the container body 11 by, for example, a method of reverting from the substantially upright state to the upright or sideways state and returning to the substantially upright state again. The operability when the piston head 14 of the foam discharger 13 is pushed in with the container 10 held can be effectively improved. You may make it hold | grip the part of the air chamber 18 and perform these operations.

The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the content liquid discharged in the form of foam does not necessarily need to be a liquid mixture for hair coloring or hair decoloration obtained by mixing the first agent and the second agent. It may be a liquid or a content liquid used in the form of various bubbles other than those used for hair dyeing and decolorization .
