Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a liquid container suitable for extracting viscous liquids such as cosmetic nail polish and correction fluid.

[Conventional technology]

In the case of conventional liquid containers such as nail polish and correction fluid, a cap with a brush is fitted onto a container such as a bottle containing a volatile viscous liquid, and when the cap is removed, the cap can be removed before use. This is a so-called brush painting process in which a viscous liquid adhered to a brush is applied.

[Problem to be solved by the invention]

With such conventional liquid containers, the cap with a brush must be removed each time it is used, and the amount of viscous liquid deposited with the brush must be adjusted while painting with a brush. There was a problem in that the viscous liquid adhered to the cap screwing part at the mouth of the container and hardened, making it difficult to open the cap, making it very inconvenient to use. Furthermore, recently, a so-called rear-end knock type liquid container has been provided, which has a brush at the tip and extracts the viscous liquid by knocking the rear end of the outer cylinder that stores the viscous liquid. However, this method has the operational difficulty of having to frequently change the grip of the outer cylinder each time when operating the rear end knocking and when applying with a brush. Similar to the case of the above-mentioned brush-equipped cap, there were problems in that it was not easy to use, such as being unable to be adjusted. This invention was made to solve the above-mentioned problems, and it is possible to smoothly supply a fixed amount of viscous liquid to a tip member such as a brush or felt pen tip by a side knock operation, without changing the grip of the outer cylinder. To provide a liquid container that can smoothly perform the side knock operation and viscous liquid application operation, is very easy to use, and is compact and convenient for carrying.

[Means to solve the problem]

The liquid container according to claim 1 of the present invention is equipped with a side knock operation means on the circumferential surface of the outer shell, which has a tank portion for storing liquid and has a tip member for applying liquid at its tip. A liquid pipe that moves in the axial direction in conjunction with a side knock operating means, and when the side knock operating means knocks, a fixed amount of liquid is force-fed from the tank system into the liquid pipe by a pumping action to the tip member. supply bomb ja
A structural part and a biasing means for returning the liquid pipe and the side knock operating means when the knock of the side knock operating means is released are provided in the outer cylinder. The liquid container according to claim 2 of the present invention is provided with a pump chamber communicating with the tank section and a communication section between the tank section in the pump chamber, and when the side knock operation means is not knocking, the communication section is provided. A valve body is connected to the rear end of the pump chamber via a cylindrical adapter, and is connected to the rear end of the pump chamber via a cylindrical adapter. The bombing mechanism section according to claim 1 is modified by a piston section that has a liquid passage groove that communicates the chamber and the liquid pipe and performs a bombing operation, and a biasing means that biases the piston section backward. It is. In the liquid container according to a third aspect of the present invention, the tank section is provided with a pressure reduction regulating valve for maintaining the internal pressure of the tank section at the same pressure as atmospheric pressure.

[For use]

In the liquid container according to claim 1 of the present invention, when the side knock operating means is side-knocked while the outer cylinder is held in the liquid application direction, the liquid pipe moves backward in conjunction with the side-knock operating means. As a result of the pumping operation of the pump mechanism section, a fixed amount of liquid is supplied under pressure from the tank system to the coating member through the liquid pipe. Therefore, the side knocking operation and the viscous liquid application operation can be performed smoothly without changing the grip of the outer cylinder, which is extremely convenient to use. In the liquid container according to claim 2 of the present invention, when the side knock operation means is not knocking, the valve body is in an open state, and the inside of the tank portion and the pump chamber communicate with each other, and the liquid from the tank portion is poured into the pump chamber. When the side knock operation means is turned off in this state, the pressure in the pump chamber increases due to the pumping action of the piston part due to the backward movement of the liquid pipe, and when the valve body closes due to the increased pressure. At the same time, the liquid in the bomb chamber sequentially flows through the liquid passage groove of the piston portion and the liquid pipe to be supplied to the tip member. In this case, only a fixed amount of liquid in the pump chamber, which is isolated from the tank part by the valve body, is supplied to the tip member, and the viscous liquid is balanced by the liquid passage groove in the piston part. The viscous liquid does not drip from the coating tip member. In the liquid container according to claim 3 of the present invention, when the side knock operation means is released, the valve body opens and the tank portion and the pump chamber communicate with each other, so that the inside of the pump chamber tends to be in a depressurized state. In this case, the internal pressure of the tank section is adjusted to the same pressure as the atmospheric pressure by the pressure reduction regulating valve, thereby preventing pressure reduction in the tank section.

In this state, the rear end side of the pump member 13 faces into the pump chamber 16 formed in the pump sleeve l5. The outer peripheral surface of the bomb member 13 is formed with a liquid passage groove 13a extending in the longitudinal direction. This liquid passage groove 13a is formed deeper than the inner diameter of the front small diameter cylindrical portion 12a of the cylindrical adapter l2.
The inside of the pump chamber 16 is communicated with the inside of the pump chamber 16. Further, the pump member l3 has a tapered rear end head 13b and a spring support shaft 13c integrally projecting from the axial center of the tapered rear end head 13b. Such a pump member l
3 is urged in the forward direction by a spring 18. The front end side of this spring 18 is fitted into and supported by the spring support shaft 13c, and the rear end side of the spring 18 is fitted into and supported by the front end opening of the rear end small diameter cylindrical portion 15c of the pump sleeve 15. This is a small diameter portion 18a. Further, a ball valve (valve body) 17 is housed in the small-diameter cylindrical portion 15c at the rear end of the pump sleeve 15 for opening and closing a liquid passage port 15d communicating with a tank portion 50 for storing liquid, which will be described later. This ball valve 17 is maintained in an open state by the hydraulic pressure of the tank portion 50 unless the side knock operation lever 8 is knocked. The ball valve 17 is prevented from falling out of the rear small diameter cylindrical portion 15c by the rear end throttle small diameter portion 113a of the spring 8. Further, the front end opening of an atmosphere opening sleeve 19 is fitted and connected to the rear outer periphery of the front large diameter cylindrical portion 15a of the bomb sleeve 15. The pump sleeve 1 has a plurality of ribs 19a and a rear end wall 19b integrally formed in the direction.

This ventilation hole 19d communicates with a ventilation cylinder portion 19e that is integrally provided on the outside of the rear end wall 19b of the sleeve 19 for venting to the atmosphere. A pressure reducing regulating valve 22 for opening and closing the vent hole 19d is housed in the venting cylinder portion 19e, and the pressure reducing regulating valve 22 is always urged in the closing direction by a spring 23. The pressure reduction regulating valve 22 opens against the spring 23 due to the external pressure from the atmosphere opening chamber 21 when the pressure inside the tank section 50 is reduced, so that the internal pressure of the tank section 50 becomes equal to the atmospheric pressure. The reduced pressure inside the tank section 50 is adjusted so that Further, the tip of a pressure reducing adjustment vent pipe 24 extending to the vicinity of the inner part of the tank section 50 is inserted into and connected to the vent pipe section 19e, and the vent pipe 24 compresses the spring 23. Furthermore, a ball 51 for stirring the viscous liquid is housed in the tank section 50. Next, the assembly of the liquid container according to the present invention will be explained. First, by press-fitting the tip pipe holder 6 from the rear into the tip 4 equipped with the brush 5, the tip 4 and the tip pipe holder 6 are made into a unit. As a result, the tip of the liquid extraction pipe 7, which has been inserted and fitted into the central cylindrical portion 6a of the tip pipe holder 6, enters into the bundle of brushes 5. Next, after fitting the tip 4 unitized with the tip pipe holder 6 into the tip joint cylinder 3 from the rear as described above, the large diameter pipe section 7b on the rear end side of the small diameter pipe section 7a is inserted into the front section. While inserting into the large-diameter hole 101 at the tip of the outer tube 1A, the female screw section 3C at the rear end of the tip joint tube 3 is screwed into the male screw section 100b of the front outer tube IA. As a result, the end pipe holder 6 and the unitized tip 4 are connected to the tip of the front outer tube IA via the tip joint tube 3. Next, the rotating support piece 8a of the side knock operating lever 8 is fitted and supported in the knock lever support groove 104 of the front outer cylinder IA, and the side knock operating lever 8 is fitted into the side knock operating hole 103. After this, the rear cylindrical part 1 of the front outer cylinder IA
The support shaft 9a of the rotary lever 9 is rotatably fitted into the notch engaging stepped portion 105a through the inside of the rotary lever 9 to be supported. As a result, the lever pressing piece 8b of the side knock operation lever 8 and the front end engaging piece 10a of the rotary lever 9 are interlocked with each other. Next, the liquid pipe 10 is inserted from inside the rear cylindrical part 106 of the front outer cylinder IA into the notch 9d (see FIG. 4) of the rotary lever 9, and the tip side of the liquid pipe 10 is inserted forward. Insert into the small diameter hole 102 on the tip side of the external cylinder IA. As a result, the distal end side of the liquid pipe IO is slidably inserted and connected into the large diameter pipe portion 7b at the rear end of the liquid extraction pipe 7. In this state, the rear large-diameter cylindrical portion 12b of the cylindrical adapter 12, which is integrally connected to the rear end of the liquid pipe IO, protrudes rearward from the rear end of the front outer cylinder IA. Therefore, the inner cylinder part 2a of the cylindrical joint 2 is externally fitted onto the rear large diameter cylinder part 12b of the cylindrical adapter l2, and the front male screw part 2e of the cylindrical joint 2 is connected to the front outer cylinder IA. Rear end female thread part 1
Screw into 06a. As a result, the liquid pipe IO is connected to the i11 part outer cylinder I.
It is held so that it does not slip out backwards from inside A. Next, the axial pump member 13 is inserted into the inner cylindrical portion 2a of the cylindrical joint 2 from the rear end side.
4 is loosely fitted in advance, and the front end of a spring 18 is fitted and connected to the spring support shaft 13c in advance. In this state, the distal end side of the shaft-like pump member 13 is fitted and connected into the rear large-diameter cylindrical portion 12b of the cylindrical adapter l2 through the inside of the inner cylindrical portion 2a. Next, with the ball valve 17 housed in the small-diameter cylindrical portion 15c at the rear end of the bomb sleeve l5, the large-diameter cylindrical portion 15a at the front end of the pump sleeve 15 is connected to the inner cylindrical portion 2a of the cylindrical joint 2 and the outside. It is inserted and connected to the cylindrical portion 2b from the rear. As a result, the narrow diameter portion 18a of the spring 1st
is press-fitted to the front end opening edge of the rear end small diameter cylindrical portion 15c of the pump sleeve 15 to prevent the ball valve 17 from falling out of the rear end small diameter cylindrical portion 15c. Next, the front end side large diameter cylindrical portion 15a of the pump sleeve 15 is
After fitting and connecting the front end side of the sleeve 19 for opening to the atmosphere to the rear part of the rear outer cylinder IB in which the viscous liquid is stored in the tank part 50.
The atmosphere opening sleeve 19 is inserted from the ventilation pipe 24 side, and the front female threaded portion of the rear outer cylinder IB is screwed into the rear male threaded portion 2f of the cylindrical joint 2. In addition, the above-mentioned atmosphere opening sleeve I9 is attached to the above-mentioned rear outer cylinder IB.
It may be fitted and equipped in advance. Finally, the cap 41 is removably fitted onto the front end side of the front outer cylinder IA, completing the assembly of the liquid container. The cap 41 is designed to have a length that can protect the side knock operating lever 8 from the outside so that the side knock operating lever 8 is not pressed excessively when carrying the liquid container. Further, in the inner part of the cap 41, as shown in FIG. 4 liters of wetting material impregnated with Next, the operation will be explained. First, when using the liquid container, remove the cap 4l, hold the outer cylinder 1 in the brush painting position, and knock the side knock operating lever 8 with your fingertips.The lever pressing piece 8b of the side knock operating lever 8 When the front end engaging piece 9b of the rotary lever 9 is pressed, the rotary lever 9 rotates counterclockwise in FIG. 1 about the support shaft 9a. As a result, the pipe interlocking piece 9c of the rotating lever 9 pushes the engaging piece 10a of the liquid pipe 10 rearward. As a result, the shaft-like pump member 13 moves backward against the spring 18 via the cylindrical adapter 12 integrated with the liquid pipe IO. Here, when the side knock operation lever 8 is in the non-knocking state, the ball valve 17 is opened, and the viscous liquid flows into the pump chamber 16 from the tank portion 50 through the liquid passage opening 19c and the liquid passage opening 15d. is in a state of From this state, when the pump member l3 is moved backward into the pump chamber 16 by the knock of the side knock operation lever 8 as described above, the hydraulic pressure within the pump chamber 16 increases. Due to the increase in hydraulic pressure, the ball valve 17 closes, and at the same time,
The viscous liquid in the pump chamber 16 flows through the liquid passage groove 13a of the pump member 13, passes through the liquid pipe 10, and is supplied from the liquid extraction pipe 7 to the brush 5. In this case, a certain amount of viscous liquid corresponding to the increase in the hydraulic pressure in the pump chamber 16 corresponding to the distance of the backward movement of the pump member 13 is supplied to the brush 5 through the liquid passage path. Therefore, the user can adjust the amount of knocking or the number of knocks of the side knock operation lever 8 to control the brush 5.
The amount of viscous liquid supplied can be adjusted to an appropriate amount. Moreover, the viscous liquid in the pump chamber 16 is not directly pumped into the liquid pipe 1a by the bombing action caused by the backward movement of the pump member 3 as described above, but is instead passed through the outer circumference of the pump member 13 as described above. Since it flows gently through the groove 13a and reaches the inside of the liquid pipe 10, it is supplied from inside the liquid pipe 10 to the brush 5 via the liquid extraction pipe 7.
Unless the knocking operation of the side knock operation lever 8 is repeated excessively, there is no risk of the viscous liquid dripping from the brush 5. Therefore, the brush 5 to which the viscous liquid has been supplied as described above can comfortably apply nail polish, correction fluid, etc. Further, when the pump member 13 is moved backward by a knock operation of the side knock operation lever 8, a cylindrical adapter 12 that moves the pump member 13 backward together with the liquid pipe 10 is attached to the rear large diameter cylindrical portion 12b. The end also moves the stepped sleeve 14 backward. Due to this backward movement of the stepped sleeve 4, the rear end of the inner cylindrical portion 2a of the cylindrical joint 2 opens, thereby opening the atmosphere opening chamber 2.
l communicates with an air flow passage 20 through an air hole 15d, and the air flow passage 20 is opened to the atmosphere through a gap between the front outer cylinder IA and the side knock operation hole 103. Thereby, the pressure inside the atmosphere open chamber 2l is maintained at the same pressure as the atmospheric pressure. Therefore, when the pressure inside the tank portion 50 is reduced, the pressure reduction adjustment valve 22 is opened by the atmospheric pressure acting on the pressure reduction adjustment valve 22 from the atmosphere open chamber 21, and outside air flows into the tank portion 50 from the ventilation pipe 24. As a result, the pressure inside the tank section 50 is maintained at the same pressure as the atmospheric pressure. Therefore, when the side knock operation lever 8 is not knocking, the ball valve 17 opens, and the viscous liquid flows smoothly into the pump chamber 16 into the tank section 50, causing the pressure inside the tank section 50 to decrease. Therefore, there is no possibility that the viscous liquid will not be supplied to the brush 5. Further, when the knock of the side knock operation lever 8 is released, the pump member 13 moves forward by the biasing force of the spring 1, and the cylindrical adapter 12 and the liquid pipe 10 move forward together with the pump member 13. , the rotating lever 9 engaged with the engaging piece 10a integrated with the liquid pipe 10 rotates clockwise in FIG.
The side knock operation lever 8, which is linked to this, returns to its original position. In this case, as the pressure inside the pump chamber 16 is reduced due to the forward movement of the bomb member 13 as described above, the ball valve l7
The valve opens with viscous liquid pressure from 0, and the viscous liquid flows into the pump chamber 16.
The inside is filled with inflow. Therefore, by repeatedly knocking the side knock operation lever 8, a fixed amount of viscous liquid is always supplied to the brush 5. It goes without saying that packing may be interposed between the constituent members of the liquid container described in the above embodiments, if necessary. In addition, in order to make the side knock operation lever 8 easier to knock, it is possible to make the opening edge of the side knock operation hole 103 thinner or to change the shape of the side knock operation lever 8 as appropriate. It is possible.

【Effect of the invention】

As described above, according to the present invention, by side-knocking the side-knock operating means with a fingertip while holding the outer cylinder in the application position, the bombing operation of the pump mechanism linked to the side-knock operating means is activated. Since a fixed amount of viscous liquid can be supplied to the tip application member such as a brush or felt material, the side knock operation and the viscous liquid application operation can be performed smoothly without changing the grip on the outer cylinder. This has the effect of providing a liquid container that can prevent viscous liquid from dripping from the distal application member, is very easy to use, is easily compact, has a good appearance, and is convenient to carry.
