Description

  The present invention relates to a liquid dispensing container.

  Various containers that can measure and dispense a fixed amount of liquid in the container have been proposed. (For example, see Patent Document 1)

  The liquid metering stopper described in Patent Document 1 is provided with a portion that can be fitted to the container mouth, and a suction pipe at the lower part of the cylinder, and the suction pipe communicates with the metering chamber inside the cylinder. In addition, a first check valve for preventing the backflow of liquid from the metering chamber to the suction pipe is provided at the lower part of the cylinder. In addition, a piston that is inserted into the cylinder is suspended inside the cap, and a piston is provided with a vent hole. The vent hole is provided so that the metering chamber communicates with the outside of the piston. A second check valve is provided to prevent backflow of air into the chamber. Furthermore, an air hole is provided in the cylinder, and the air hole is provided so that the outside of the cylinder communicates with the inside of the container in which the cylinder is mounted.

  In the liquid metering stopper described in Patent Document 1, the liquid that has entered the metering chamber does not flow backward into the container body, and therefore, a certain amount can be accurately dispensed, and it can be poured over time. It will not be inaccurate even if you put it out. Further, since there is no possibility of backflow from the suction pipe, the suction pipe can be made large in diameter, the resistance at the time of liquid suction is small, and the cap can be removed easily. Furthermore, since the liquid is sucked and filled in the metering chamber, and then the cap and the piston are removed from the container mouth and poured out, the liquid in the metering chamber can be discharged at once.

  As described above, the present invention can accurately dispense a fixed amount, and can easily measure and dispense the metered solution without removing the piston, and is easy to handle. We propose a liquid dispensing container that is easy to dispense and that can be easily primed at the beginning of use.

  The first means is configured as follows. That is, the container body A in which the mouth / neck part 11 is erected from the body part 10, the upper end part of the mouth / neck part 11 is liquid-tightly fitted and fixed, and the lower end part is suspended in the container body A. A cylinder B provided with a suction valve 33 at the bottom and an annular piston 40 fitted to the inner periphery of the cylinder B so as to be liquid-tightly slidable project from the lower part of the outer periphery. It is mounted so as to be movable, and is provided with a communication path p communicating with the inside of the cylinder B at the lower part, and with a metering chamber R having an upper end opening communicating with the communication path p via a check valve 42 above the communication path p. The top wall 81 extends from the upper end edge of the vertical movement member D and the peripheral wall 80 detachably fitted to the outer periphery of the container body neck portion 11, and the vertical movement member D is pressed and locked to the lowest position. And a vertical movement member with the cap F removed at the upper end of the vertical movement member D. Pushing a is possible and quantitative chamber dispense capable pressing the lid E of the liquid in the R, provided detachably.

  The second means is configured as follows. That is, in the first means, the support bar 35 is supported upright at the center of the lower part of the cylinder B, and a plurality of guide protrusions 44 are provided on the inner periphery of the connecting path p of the vertical movement member D in the circumferential direction. The periphery was slidably fitted.

  The third means was configured as follows. That is, in the first means or the second means, the pressing inner lid E is detachably fitted to the upper end portion of the vertical movement member D across the upper portion of the fixed amount chamber R. .

  The fourth means is configured as follows. That is, in any one of the first to third means, the upper end portion of the vertical movement member D is outward from the upper end edge of the cylindrical peripheral wall 53 that defines the metering chamber R inside. The flange 54 is extended, the base end portion is cylindrical from the outer periphery of the flange 54, and an enlarged cylindrical portion 55 that gradually increases in diameter as it goes upward is extended. A top wall portion 70 detachably fitted to the inner surface of the enlarged diameter cylindrical portion 55 across the upper part of the chamber R, and a top plate portion 70 detachably fitted to the inner periphery of the peripheral wall 53 from the back surfaces of both sides.

  According to the present invention, when the cap F is removed, the vertically moving member D is automatically raised, and since the quantified liquid previously measured exists in the quantifying chamber R of the vertically moving member D, the state remains as it is. The metered solution can be dispensed with Further, after use, simply closing the cap F causes the vertical movement member D to descend, so that the liquid in the cylinder B enters the communication path p, and the pressurized liquid in the communication path p opens the check valve 42. After being introduced into the quantification chamber R, the quantification liquid is again introduced into the quantification chamber R. Therefore, the liquid can be transferred and measured only by attaching and detaching the cap F, which is very convenient in handling.

  In addition, a detachable inner lid E is provided at the upper end of the vertical movement member D so that the vertical movement member D with the cap F removed can be pushed in and the liquid in the metering chamber R can be poured out. Therefore, at the beginning of use of the liquid dispensing container, it is predicted that air is present in the cylinder B or the vertical movement member D. At that time, by pressing the inner lid E for pressing, The vertical movement member D can be easily moved up and down, so that each part can be easily filled with liquid, and so-called priming operation can be easily performed. Moreover, in use, after the pressing inner lid E is pressed and the vertical movement member D is pushed down to the lowest position to introduce the metering solution into the metering chamber R, the metering solution can be easily poured again by releasing the press. It is possible, and there is also an advantage that continuous dispensing of the quantification solution can be performed very easily.

The lower member D1 further includes a first lower member D1a, a second lower member D1b, It consists of. The first lower member D <b> 1 a has a plurality of circumferentially extending guide protrusions 44 projecting inward from the inner peripheral lower end of the cylindrical portion 43. Each guide protrusion 44 abuts the outer surface of the support bar 35 so that the inner surface is slidable, and each guide protrusion 44 and the support bar 35 contribute to stable vertical movement of the vertical movement member D.

  The second lower member D1b has a small-diameter cylindrical portion 48 raised from the upper end of the large-diameter cylindrical portion 46 via the flange 47, and the annular piston 40 is integrally projected outward from the lower end edge of the large-diameter cylindrical portion 46. Yes. Then, the upper part of the cylindrical part 43 of the first lower member D1a is fitted and fixed to the inner periphery of the large-diameter cylindrical part 46, and both are fitted and integrated, and the communication path p is formed in the cylindrical part 43 and the large-diameter cylindrical part 46. It is defined.

  The upper member D2 hangs down a fitting cylinder 50 to be fitted on the outer periphery of the small diameter cylinder portion 48 of the second lower member D1b downward from the periphery of the window hole 52 formed in the center of the bottom wall 51. A peripheral wall 53 stands up from the peripheral edge. A lower end portion of the peripheral wall 53 is formed in a small diameter portion 53 a, and an enlarged diameter cylindrical portion 55 is extended from the upper end portion via a flange 54. The diameter-expanded cylindrical portion 55 has a cylindrical base end and gradually increases in diameter as it goes upward. Then, the fitting cylinder 50 is fitted and fixed to the outer periphery of the small diameter cylinder portion 48 of the lower member D1, and the lower member D1 and the upper member D2 are fitted and integrated.

  The check valve member D3 is provided on the inner peripheral lower portion of the fitting cylinder 60 fitted to the inner periphery of the small diameter portion 53a of the upper member D2 via a plurality of circumferential elastic plates 61 having the same form as the suction valve 33. The check valve plate 62 is supported, and the check valve 42 is configured by pressing the bottom peripheral portion of the check valve plate 62 against the valve seat formed by the peripheral portion of the window hole 52.

  The vertically moving member D configured as described above allows the annular piston 40 to be slidably fitted to the inner periphery of the cylinder B, and between each step portion 34b of the support base 34 and the lower surface of the large-diameter cylindrical portion 46. A coil spring s is interposed between the cylinder B and the cylinder B so as to move up and down. And it communicates from the cylinder B to the communication path p, and from the communication path p to the metering chamber R through the check valve 42 unilaterally.

  The pressing inner lid E includes a top wall portion 70 that traverses the central portion of the upper member D 2, and an arcuate plate-like hanging wall portion 71 is suspended from both sides of the top wall portion 70 to the inner periphery of the upper member peripheral wall 53. Further, the peripheral edge portions on both sides of the top wall portion 70 are fitted on the flange 54 of the upper member D2, and are detachably mounted. A circular bulge 72 is projected from the center.
