Then, since these openings 100 g, 100 g ₂ is configured so as to penetrate to the back, foam mixture filled in the decorative flow path 14s, these openings 100 g, enter up to 100 g _2. With such a configuration, the user of the discharge container 100 looks at the decorative pattern forming plate 14p through the window plate 14f to obtain a foam-like mixture in the shape of the decorative pattern (a dog's face in the present embodiment). It can be viewed visually.

  The nozzle head 14 also includes a head ring 14 c located radially outward of the hollow neck 1 c of the base cap 1 when the nozzle head 14 is pressed down. A communication hole 14m is provided at the top of the head ring 14c, and a space between the head ring 14c and the inner cylindrical wall 14d can introduce air from the outside through the communication hole 14m.

  By the way, as shown in FIG. 1, the cylindrical body 15 is provided in 2nd ventilation path A2. In the present embodiment, the inner peripheral surface of the cylindrical body 15 is fitted to the upper cylindrical wall 7c of the hollow stem 7, and the outer peripheral surface of the cylindrical body 15 is fitted to the lower cylindrical portion 14g of the nozzle head 14. . Further, on the upper portion of the cylindrical body 15, a plurality of ribs 15a (provided at intervals in the circumferential direction) extending radially inward and covering the tip of the upper cylindrical wall 7c, and the ribs An annular portion 15b is provided for closing the outer peripheral side of 15a. As a result, between the ribs 15a, the inlet side opening to the upper side to introduce the air from the air pump 3 and the opening to the radially inner side to discharge the air toward the merging space G A communication passage including the side opening is to be formed. Further, a longitudinal groove 15 c is provided on the outer peripheral surface of the cylindrical body 15. Thus, a passage through which the air from the air pump 3 flows is formed between the lower cylindrical portion 14g of the nozzle head 14 and the vertical groove 15c.

  Furthermore, the flat-shaped thin-walled valve 16 pinched by the annular wall 14h and the rib 15a is provided in 2nd ventilation path A2. The thin-walled valve 16 covers both the rib 15a and the annular portion 15b, and the outer edge portion extends to the inside of the longitudinal groove 15c.

  Further, as shown in FIG. 1, a stopper 17 is provided between the top wall 1a of the base cap 1 and the head ring 14c to prevent the nozzle head 14 from being inadvertently depressed. The stopper 17 is substantially C-shaped in a plan view, and can be detachably attached from the side of the hollow neck 1 c.

  In the discharge container 100 thus configured, when the stopper 17 shown in FIG. 1 is removed and the nozzle head 14 is pushed in, the hollow stem 7 slightly slides relative to the air piston 10 by the size L. In other words, the slide of the air piston 10 starts behind the slide of the hollow stem 7 by the size L. As a result, as shown in FIG. 1, the lower end portion of the cylindrical guide 10a separates from the intermediate flange 7b, and the inside of the air piston 10 communicates with the first air passage A1. Then, when the pushing of the nozzle head 14 is continued, the air inside the air piston 10 is pressurized by the movement of the air piston 10 and is introduced from the first air passage A1 into the vertical groove 15c. The outer edge is lifted and separates from the annular portion 15b. Thereby, the air which flows in from the vertical groove 15c flows toward the merging space G via the communication path formed between the ribs 15a.

  On the other hand, in the small diameter cylindrical body 4a, the valve portion 6a of the poppet 6 abuts against the inner surface of the small diameter cylindrical body 4a to close the suction port 4c and the inside of the small diameter cylindrical body 4a is pressurized. The valve portion 6 b of the poppet 6 separates from the outlet of the internal passage t 1 in the piston 5, and the content fluid present in the internal passage t 1 flows into the internal passage t 2 of the hollow stem 7. And it flows into the confluence space G through the passage formed between the legs 9b.

Then, the content liquid in the gas-liquid mixed state in the merging space G passes through the reduced diameter portion 13 and the mesh ring 12 to form a foam, and passes through the mixing flow path M to the decoration flow path 14s of the nozzle head 14 Led. The decorative flow path 14s is formed such that a foamy mixture led from the mixing flow path M spreads in a circumferentially extending space orthogonal to the mixing flow path M. And since the mixing flow path M is located substantially at the center of the decoration flow path 14s, the foam-like mixture will be distributed approximately uniformly throughout the decoration flow path 14s. Further, when the foam mixture is to be filled into the decorative passages 14s, opening 100g of some of them decorative pattern forming plate 14p, since the entering into 100g _2, the user of the dispensing container 100, mesh It is possible to visually recognize a foamy mixture visualized in the shape of the decorative pattern from the direction opposite to the ring 12 through the window plate 14f. Furthermore, the decorative flow channel 14s communicates with the inner space of the nozzle cylinder 14k protruding in the outer circumferential direction from the head peripheral wall 14r, and the foamy mixture guided from the mixing flow channel M is the inner space of the nozzle cylinder 14k. The ink is discharged from the discharge port 14a via.

Thus, the user of the discharge container 100 of the present embodiment fills the foamy mixture in the decoration flow path 14s by the pressing operation of the nozzle head 14 and enters the openings 100g and 100g ₂ of the decoration pattern forming plate 14p. It can be visually recognized from the upper side of FIG. 1 through the window plate 14f. Therefore, when the discharge container 100 of the present embodiment is used by a child, the decorative flow path 14s and the decorative pattern forming plate 14p are filled with the foamy mixture to cause an intellectual change. Is stimulated to be used repeatedly. Therefore, a child can acquire the habit of hand washing using this discharge container 100. In addition, since the foam state of the mixture in the decorative flow path 14s is not maintained for a long time, for example, a guardian of a child may immediately open the openings 100g, 100g ₂ and the decorative flow path of the decorative pattern forming plate 14p. By visually observing the foamy mixture in 14s through the window plate 14f, it is possible to confirm whether the child performed the hand washing using the discharge container 100 or not.

  The nozzle head 14 can be formed of various materials such as moldable resin, but the decorative pattern forming plate 14p, the decorative wall portion 14w and the decorative ceiling wall 14t are in view of the visibility of the decorative pattern. Therefore, it is desirable to use colors other than white. More specifically, the color of the decorative pattern forming plate 14p, the decorative wall portion 14w, and the decorative ceiling wall 14t is, for example, a mixture of foam-like decorative channels 14s by selecting a color such as black, navy or red. The decorative pattern can be made more visible when filled with In addition, as the window plate 14f for visual recognition, various materials such as resin, glass, and the like can be used as long as they have translucency to visible light. For example, in the case of using a synthetic resin as the material of the window plate 14f, polypropylene, polyethylene terephthalate, or a copolymer of polyethylene terephthalate can be used. Further, in order to prevent the foamy mixture from entering the gap between the decorative pattern forming plate 14p and the window plate 14f, a relatively soft material such as an elastomer can be used as a material of the window plate 14f. By this, when the nozzle head 14 is pushed in, the sealing property between the window plate 14f and the decorative pattern forming plate 14p is improved, so that the decorative pattern can be beautifully raised.

Further, in the present embodiment, since the decorative pattern forming plate 14p is provided as a separate part, a soft material can be used for the decorative pattern forming plate 14p. In this case, a hard material can be used without using an elastomeric soft material for the window plate 14f, and the light transmission can be ensured. When the decorative pattern forming plate 14p is formed of a relatively soft material such as an elastomer, the decorative pattern forming plate 14p is formed in accordance with the shape of the decorative pattern in order to prevent the entry of bubbles into the gap with the window plate 14f. Ribs (projections) may be formed on the side. As a result, the sealability between the window plate 14f and the decorative pattern forming plate 14p is improved, and a foamy mixture does not enter the area other than the openings 100g and 100g _{2 of} the decorative pattern forming plate 14p. It can be beautifully raised. The window plate 14f may be engaged and fixed to the head peripheral wall 14r or the like by an engagement portion (not shown), or the head peripheral wall 14r and the window plate 14f are coupled by a hinge portion or the like (not shown). You may comprise so that it can be opened and closed.

  After the nozzle head 14 is completely cut off, when the pressing force is removed, the hollow piston 5 and the hollow stem 7 return to the initial position by the repulsive force of the spring 8.

  In this return process, the poppet 6 moves in accordance with the upward slide of the hollow piston 5, the suction port 4c of the small diameter cylindrical body 4a is opened, and the ball valve B is seated on the inward flange 7g. The inside of the body 4a has a negative pressure, and the liquid in the container is sucked into the small diameter cylindrical body 4a from the suction port 4c.

  On the other hand, in the large diameter cylindrical body 4b, since the upward slide of the air piston 10 starts with a delay of L, the lower end portion of the cylindrical guide 10a is in contact with the intermediate flange 7b in the first air passage A1. It will be closed. In addition, the thin-walled valve 16 is in a state of covering both the rib 15a and the annular portion 15b. Therefore, when the air piston 10 slides upward, the inside of the air piston 10 becomes negative pressure, so the check valve 11 closing the opening 10d is opened, and the communication hole 14m formed in the upper portion of the head ring 14c Then, air flows in between the head ring 14c and the inner cylindrical wall 14d, the inside of the hollow neck portion 1c of the base cap 1, and the inside of the air piston 10 through the opening 10d. Further, as shown in FIG. 1, a lateral hole 4e is provided in the upper portion of the large-diameter cylindrical body 4b, and the air passing through the inside of the hollow neck 1c of the base cap 1 passes through the lateral hole 4e. It also flows inside. As a result, even if the content liquid is discharged from the container body C, the inside of the container body C does not remain in a negative pressure state.

  In this manner, by repeatedly pressing the nozzle head 14 and returning to the initial posture, the content liquid in the container can be made to be in the form of bubbles and continuously discharged.

As described above, according to the present embodiment, the content liquid in the container body C and air are mixed and foamed to form a foamy mixture, which is formed in the shape of a decorative pattern such as a character, etc. It is configured to be filled in the openings 100g, 100g ₂ and the decoration flow path 14s of the decoration pattern forming plate 14p visible from the above. As described above, by making the decorative pattern of the character or the like concrete, it is possible to create the fun of discharging the content liquid such as liquid soap and to promote the child's active hand washing and the like. In addition, the guardian of the child checks whether the child has used the content liquid by checking the foamy mixture filled in the openings 100g and 100g ₂ of the decorative pattern forming plate 14p and the decorative channel 14s. It can be confirmed.

  Further, in the present embodiment, the decorative pattern forming plate 14p is attachable to and detachable from the nozzle head 14 provided with the decorative flow channel 14s. With this configuration, when the child is a user, the decorative pattern forming plate 14p is replaced with another decorative pattern forming plate 14p having a different decorative pattern at a constant frequency, so that hand washing using the discharge container 100 can be performed. Further, it can be performed continuously.

Further, in the present embodiment, in order to visualize the foam-like decorative pattern having the shape of the decorative pattern by the decorative pattern forming plate 14p, for example, a complicated shape such as an opening 100g ₂ corresponding to a dog's eye and ear It can be easily visualized also about the decoration pattern of.

Further, according to the present embodiment, the decorative flow path 14s is a space surrounded by the head peripheral wall 14r extending in the circumferential direction centering on the mixing flow path M for guiding the foamy mixture from the mesh ring 12 upward. It was configured to be formed as a groove in the inside. As a result, the foam-like mixture is substantially uniformly filled in the decoration flow path 14s. The opening 100g of the decorative pattern forming plate 14p from the mixing channel M opposite to the direction, by a visually recognizable 100g ₂ and decorative passages 14s, opening 100g of the decorative pattern forming plate 14p, 100g ₂ and decorative The filling state of the foam in the flow path 14s can be easily visually recognized.

  The above-described embodiment is only an embodiment of the present invention, and various modifications can be made. For example, the decorative pattern forming plate 14p and the window plate 14f may be integrally configured.

  Further, in the present embodiment, the content liquid pump 2 and the air pump 3 are operated by pressing the nozzle head 14 to generate and discharge a foamy mixture, but this embodiment is limited to this aspect. I will not. For example, the container body C is formed of a squeezable flexible material, and when the user squeezes the container body C, the content liquid and air are mixed to form a foamy mixture, and decoration is performed. You may make it be led to the flow path 14s and the discharge port 14a. And, it should be understood that their configuration is also within the scope of the present invention.
