Further, it is preferable that a plurality of the forming meshes 22 are mounted on the longitudinal discharge flow path 16 in a stacked manner, and these forming meshes 22 are arranged so that the positions of the mesh holes are shifted from each other when viewed from above. It is preferable that a plurality of them are mounted. These make it possible to form finer and better foams. In addition, as a method of arranging the forming meshes 22 so that the positions of the mesh holes are shifted from each other, a method of attaching the forming meshes 22 adjacent to each other in a state where they are relatively rotated at a predetermined rotation angle in the circumferential direction. Alternatively, a method of changing the position and the number of mesh holes of the forming mesh 22 adjacent vertically can be adopted.

A space can be maintained between the portions 22b. As a result, the mesh plate is pumped from the tip supply port 26a of the liquid channel 24a and the tip supply port 26b of the air channel 24b and forms the lower surface of the lowermost forming mesh 22 before being mixed, as will be described later. After reaching the part 22b, the content liquid and the air that passed through the mesh plate part 22b through the many mesh holes and entered the back side thereof were held between the mesh plate parts 22b adjacent vertically. By passing through the upper mesh plate portion 22b while effectively mixing the space as a mixing space, it becomes possible to form finer and better foam with fine bubbles. It is also possible to form finer foams with better foam quality by raising the molded mesh.

  In the present invention, the porous member 22 attached to the longitudinal discharge flow channel 16 is foamed by mixing a content liquid such as sponge or sintered metal with air in addition to a mesh-like material such as a molded mesh 22. Various kinds of foam refining members known as members for refining the produced bubbles can be used. Further, the porous member 22 does not necessarily need to be mounted on the longitudinal discharge flow channel 16 in a stacked manner. Depending on the size, shape, etc. of the porous member 22, one or more porous members 22 can be placed in the vertical discharge flow channel 16. It can be used by mounting.

The supply port 26 a and the tip supply port 26 b of the air flow path 24 b formed by the air holes 25 are arranged in proximity to each other. In addition, the leading ends of the liquid flow path 24a and the air flow path 24b are arranged such that the content liquid supply direction extension line X from the front end supply port 26a and the air supply direction extension line Y from the front end supply port 26b are in the horizontal direction. When viewed from above, they do not extend in parallel, but are formed in a positional relationship reaching the lower surface of the lowermost porous member 22 before crossing. That is, at least on the lower surface of the lowermost porous member 22 (the lower surface of the lowermost forming mesh 22 by the mesh plate portion 22b), the content liquid supply direction extension line X and the air supply direction extension line Y are parallel to each other. The parts are designed and arranged so that they do not extend but intersect. For example, the tip supply port 26b of the air flow path 24b is arranged so as to be non-perpendicular with respect to the mesh plate portion 22b of the forming mesh 22. It should be noted that the content liquid supply direction extension line X and the air supply direction extension line Y do not intersect even on the lower surface of the uppermost porous member 22 (the lower surface of the uppermost formed mesh 22 by the mesh plate portion 22b). As described above, it is preferable to design and arrange the respective parts from the viewpoint of forming finer and fine foam bubbles.

Accordingly, the intake valve mechanism 15 is arranged from the outside air intake port 14 to the top plate outside air intake port 27 in accordance with an operation of grasping and pressing the container body 11 by hand or releasing the press. It is possible to prevent the air passing through the outside air intake passage from leaking outside the annular partition wall 34. As a result, the responsiveness of the intake valve mechanism 15 can be accelerated, and the usability of the discharge container 10 with the nozzle cap can be improved.

  Further, in this embodiment, when the lid part 12b is closed, as shown in FIG. 4, the outside air intake chamber 19 surrounds the outside air intake port 14 and protrudes downward from the inner side surface of the lid part 12b. The lower end surface of the cylindrical valve seat portion 15a is in close contact with the upper end surface 28a of the valve support piece 28 erected upward from the top plate portion 18a of the cap body portion 18 to which the valve portion 15b is cantilevered. It will contact in the state. As a result, the valve portion 15b can rotate around the connection portion with the valve support piece 28 and can be brought into close contact with the lower end surface of the cylindrical valve seat portion 15a. The intake valve mechanism 15 capable of opening and closing the outside air intake port 14 can be easily formed.

  In the present embodiment, the valve portion 15b is cantilevered to the valve support piece 28 so that a predetermined gap is formed between the valve portion 15b and the lower end surface of the cylindrical valve seat portion 15a without pressing the container body 11. (FIG. 4). And by the internal pressure rise by pressing the container main body 11, the valve part 15b elastically deforms centering on the connection part with the valve support piece 28, and contact | adheres to the lower end surface of the cylindrical valve seat part 15a.

  In the squeeze foamer container 10 of the present embodiment having the above-described configuration, the nozzle cap 12 is integrally molded with the main body part 12a and the lid part 12b being opened as described above. While the main body part 12a and the lid part 12b are in an open state, for example, three porous members 22 are stacked from above on the inside of the longitudinal discharge channel 16 by the enlarged diameter cylindrical part 21a of the two-stage cylindrical part 21 from above. Is attached. Thereafter, the body part 12a and the lid part 12b are joined and integrated by rotating the lid part 12b around the hinge joint 12c. As a result, the upper part of the lower part 20b including the discharge nozzle part 12 and the outside air intake chamber 19 is closed by the upper part 20a to form the discharge nozzle part 13 and the outside air intake chamber 19, and the outside air intake chamber. The nozzle cap 12 in which the intake valve mechanism 15 including the cylindrical valve seat portion 15a and the valve portion 15b is provided inside the nozzle cap 12 is easily formed.

  The formed nozzle cap 12 has the cap main body portion 18 in a state where the upper end portion of the dip tube 23 is attached to the reduced diameter cylindrical portion 21b of the two-stage cylindrical portion 21 provided in the cap main body portion 18. By attaching to the mouth neck part 11a, it is attached to the container main body 11 integrally. Thereby, the discharge container 10 with a nozzle cap of this embodiment is formed.

  According to the squeeze foamer container 10 of the present embodiment having the above-described configuration, the nozzle cap 12 can be formed in a compact manner while the height of the nozzle cap 12 is kept low, and the foam quality is reduced. It is possible to foam the content liquid while mixing it with air.

  That is, in the present embodiment, the porous member 22 is overlapped on the longitudinal discharge flow path 16 formed by the enlarged cylindrical portion 21a of the two-stage cylindrical portion 21 provided to be opened in the top plate portion 18a of the cap body portion 18. Since the gas-liquid mixing chamber is not provided below the porous member 22 of the vertical discharge flow path 16, the height of the vertical discharge flow path 16 can be reduced by shortening the vertical discharge flow path 16. The nozzle cap 12 can be made compact.

  In the present embodiment, the content liquid supply direction extension line X from the front end supply port 26a of the liquid flow path 24a and the air supply direction extension line Y from the front end supply port 26b of the air flow path 24b are horizontally aligned. When viewed from the direction, the tip portions of the liquid flow path 24a and the air flow path 24b are respectively formed in a positional relationship reaching the lower surface of the porous member 22 before crossing. As a result, the content liquid pumped from the tip supply port 26a of the liquid channel 24a and the air pumped from the tip supply port 26b of the air channel 24b are applied to the lower surface of the lowermost forming mesh 22 before being mixed. Therefore, when air and content liquid pass through each forming mesh 22 (each porous member 22), turbulent flow such as vortex is generated by colliding with each forming mesh, and the air and content liquid are The effect of mixing with turbulent flow makes it possible to produce fine, fine foam with good foam quality.

  Therefore, according to the squeeze foamer container 10 of the present embodiment, even when no gas-liquid mixing chamber is provided or when the gas-liquid mixing chamber is provided at a low height, the fineness is reduced without reducing the foam quality. As a foam, the content liquid can be foamed while being mixed with air.

  In addition, according to the present embodiment, the nozzle cap 12 has a two-part configuration including the main body part 12a and the lid part 12b, and the vertical discharge is performed with the lid part 12b being opened with respect to the main body part 12a. For example, the porous member 22 for foaming the content liquid can be easily and smoothly mounted and attached to the longitudinal discharge flow channel 16 by work or operation from above the flow channel 16, so that the conventional discharge with a nozzle cap can be performed. Like a container, a vertical discharge flow path including a porous member, a valve mechanism, etc. is formed by a member different from the nozzle cap, and assembled later on the nozzle cap, or by work or operation from below the nozzle cap. There is no need to attach a porous member, a valve mechanism, or the like to the vertical discharge flow path, and the vertical discharge flow path can be easily formed integrally with the nozzle cap 12. It can be. This makes it possible to further simplify the structure and assembly process of the nozzle cap. This also allows the nozzle cap 12 to be formed with a lower height, making it possible to easily reduce the size of the container and effectively reducing the number of parts and the amount of resin used. Thus, it can be formed at a lower cost.

  Furthermore, according to the squeeze foamer container 10 of the present embodiment, after the nozzle cap 12 is formed integrally with the main body part 12a and the lid part 12b being opened, the lid part 12b is rotated and closed. The intake valve mechanism 15 for opening and closing the outside air intake port 14 as a part of a separate part of a different material from the resin material of the nozzle cap 12 by a simple structure and assembly process that is simply joined and integrated with each other. It becomes possible to provide easily without using a separately formed valve member.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the squeeze foamer container of the present invention, the lower surface of the porous member does not necessarily have to be disposed close to the front end supply port of the liquid flow path and the front end supply port of the air flow path. An interval may be maintained between the supply port and the tip supply port of the air flow path. Even when a gas-liquid mixing chamber is interposed between the lower surface of the porous member and the tip supply port of the liquid channel and the tip supply port of the air channel, the content liquid from the tip supply port of the liquid channel When the supply direction extension line and the supply direction extension line of air from the tip supply port of the air flow path are viewed from the lateral direction, the liquid flow path has a positional relationship reaching the lower surface of the porous member before intersecting. And if the front-end | tip part of an air flow path is each formed, it is included in this invention.

  Further, the nozzle cap does not necessarily have a two-part configuration including a main body part and a lid part, and the lid part does not necessarily need to be connected to the main body part via the hinge joint. The lid part may be molded as a separate part from the main body part. Further, the porous member does not necessarily have to be mounted from above the vertical discharge flow path in a state where the lid part and the main body part are not joined and integrated. For example, as shown in FIG. 6, the two-stage cylindrical portion 21 ′ in which the upper diameter expanded cylindrical portion 21 a ′ is a longitudinal discharge flow channel 16 ′ to which the porous member 22 ′ is mounted is replaced with a main body part 12 a ′. It is molded as a separate part and attached as a single piece so as to be fitted from below into the top plate 18a ′ of the cap body portion 18 ′ of the main body part 12a ′ with the porous member 22 ′ and the dip tube 23 ′ attached. Thereby, it can also be set as the nozzle cap which comprises the squeeze foamer container of this invention.

  Further, the valve part does not necessarily need to be cantilevered in the main body part, and may be a valve part provided with a large number of valve pieces by, for example, inserting a plurality of through slits radially from the center of the rubber plate. In this case, it is preferable to attach the rubber plate so that the center of the rubber plate (starting point of the radial through slit) coincides with the axial center of the cylindrical valve seat portion. For example, there is a method of fixing by sandwiching between a main body part and a lid part. A ball valve using a sphere made of resin or the like can also be used. For example, instead of the valve support piece, the ball valve is provided with a cylindrical body having an inner diameter larger than the outer diameter of the sphere on the main body part side, concentrically with the outside air intake, and the inner diameter near the upper and lower openings is set outside the sphere. The squeezing is gradually made smaller than the diameter so that the sphere does not come out of the cylindrical body. The sphere is normally arranged at the bottom of the cylindrical body by gravity, but the sphere moves up and down in the cylindrical body as the container body is pressed or released, and the outside air intake port is opened and closed. Done smoothly. When the sphere is in contact with the upper opening inside the cylindrical body by pressing the container body and the internal pressure, the dimensions of the sphere and the cylindrical body are set so that the outside air is blocked from the inside of the container body. On the other hand, when the pressure on the container body is released and the sphere comes into contact with the lower opening inside the cylindrical body, the dimensions of the sphere and the cylindrical body are set so that the outside air is not blocked from the inside of the container body. It is preferable.
