Description

  The present invention relates to a two-component mixing sprayer, and more particularly to a mixing sprayer in which two components are mixed at a constant ratio and sprayed in a constant amount.

As a sprayer, a trigger type sprayer in which two kinds of liquids are mixed and sprayed has been conventionally known (see, for example, Patent Document 1).
The trigger type sprayer described in Patent Document 1 sprays a mixed liquid, but as a trigger type sprayer, there is a problem that it cannot be sprayed in a narrow range, and each liquid can be accurately measured and mixed. There wasn't.

In addition, there are conventionally known dispensing containers in which two different kinds of liquids are separately integrated into two syringe-like cylindrical containers, and at the same time, different liquids are poured and mixed in a fixed amount (for example, , See Patent Document 2).
The prior art described in Patent Document 2 is only for mixing and pouring two liquids, and the liquid mixture cannot be sprayed.

Next, the usage mode and operation effects of the two-component mixing sprayer of the present invention will be described.
The two-component mixing sprayer of the present invention is used as a drug, cosmetic, or other two-component mixing sprayer.

  First, the assembly of the two-component mixing sprayer will be described. As shown in FIG. 6, the temporary lid d is fitted on the dispensing cylinders 4a and 4b of the large and small diameter cylinders A1 and A2 of the container body A. The different liquid contents are accommodated in the cylindrical walls 1a and 1b, and the piston bodies 10a and 10b of the piston members B1 and B2 are inserted into the cylindrical walls 1a and 1b.

At that time, the engaging ribs 9a, 9b at the lower ends of the cylindrical walls 1a, 1b are brought into engagement with the first protrusions 18a, 18b of the piston linkages 16a, 16b, and the diameters of the cylindrical bodies A1, A2 Are different from each other, a certain proportion of the content liquid is stored in the cylindrical bodies A1 and A2.
Thus, the container main body A of the two-type mixing sprayer in which the cylindrical bodies A1 and A2 are filled with a predetermined amount of different content liquids is obtained.

In use, first, the container body A is erected, the temporary lid d is removed, and the nozzle member C is attached to the dispensing cylinders 4a and 4b as shown in FIG.
At that time, the extraction cylinders 4a and 4b are inserted into the insertion holes 27a and 27b of the nozzle member C, and the bulging rings 6a and 6b of the extraction cylinders 4a and 4b are engaged with the recesses 28a and 28b. By engaging the locking protrusions 29a and 29b at the lower ends of the fitting insertion holes 27a and 27b on the lower side of 6a and 6b, between the upper ends of the extraction cylinders 4a and 4b and the upper wall 30 of the attachment portion 25, Positioned at predetermined intervals and attached.

  When spraying, the nozzle body 26 is directed in a desired spraying direction, the gripping part 7 or the bulging rings 8a and 8b and the push plates 19a and 19b at the lower ends of the cylindrical bodies A1 and A2 are gripped with fingers and pressed. The liquid contents in the cylindrical bodies A1 and A2 enter the flow path 35 from the liquid chambers 31a and 31b and are mixed to some extent, and further enter the annular flow path 42 and are mixed, and the two liquids pass through the spin grooves 41. It is completely mixed and ejected from the ejection port 40.

  When the piston member B is pressed during spraying, the projections 18a and 18b of the linkages 16a and 16b of the operating rod 11 are engaged with the engagement protrusions 9a and 9b at the lower ends of the cylindrical walls 1a and 1b, and a click motion is generated. Will be granted.

Therefore, when the pressing plates 19a and 19b are pressed strongly again, the protrusions 18a and 18b of the linkages 16a and 16b get over the engaging protrusions 9a and 9b at the lower ends of the engaged cylindrical walls 1a and 1b, and continue as they are. The protrusions 18a and 18b are rapidly pressed and stopped again.
Therefore, when the protrusions 18a, 18b get over the engaging protrusions 9a, 9b, the spray on the content liquid of the piston bodies 10a, 10b becomes faster and the spray becomes finer, and the next protrusions 18a, 18b A certain amount of the content liquid is poured out from the top walls 1a and 1b and sprayed until the engagement protrusions 9a and 9b are engaged.

  When the desired spraying is finished and the content liquid remains, the nozzle member C is removed, and the temporary lid d is fitted and stored.

  When the pressing plates 19a and 19b are pressed, if one of the pressing plates 19a and 19b is pressed due to the presence of the overlapping portion, both piston members are operated at the same time, and a constant content of liquid is always poured out. .

Next, another embodiment will be described.
In the above-described embodiment, the extraction cylinder is provided on the top wall of each cylindrical body. However, a single extraction cylinder may be provided between the cylindrical bodies.

In FIG. 7, reference numeral 50 denotes a pour tube installed between the top walls 2a and 2b of the cylinders A1 and A2, and the pour tube 50 communicates with the cylinders A1 and A2. Two pouring holes 51a and 51b are perforated.
Ca is a nozzle member and includes an attachment portion 52 and a nozzle body 53.
The mounting portion 52 includes an upper wall 54 and a side peripheral wall 55, and a locking ring 57 that engages with a bulging ring 56 provided on the pouring cylinder 50 is provided on the inner periphery of the lower end of the side peripheral wall 55. A liquid chamber 58 is formed between the upper end of the outlet tube 50 and the upper wall 54.
