Liquid ejection device

The present invention relates to a spraying device which is operated by a trigger lever to cause a liquid such as a cosmetic, a medicine, a fragrance, a deodorant or the like contained in a container to be ejected or foamed. A spray device in the form of a spray.

In the case of a plate type type of spray device, in general, such a lever puller is operated by moving a piston mechanism connected to a liquid discharge port of the injector body up and down, thereby causing the liquid in the container to be ejected to the outer space. If there is an unexpected accident during such handling, the contents of the trigger lever will overflow when the trigger of the trigger is actuated.

Here, it has been known in the past that an organ that can prevent the trigger from being pulled by a suitable stopper at the discharge port of the atomizer main body is described (see Patent Document 1); The screw thread of the plate-type sprayer may become loose. As a method to remove this concern, the protruding portion of the shoulder of the container is provided with an integral type of slewing stop piece, and this new type is proposed. Refer to Patent Document 2".

Further, the ejection device of the plate type or the like is operated by the trigger lever to eject the contents of the liquid container connected to the discharge port to the external space, but in use, from the erect state to the inverted state, including the so-called various states and The use of the "lying state" has a situation in which the liquid in the container is stored in the upper portion of the container and the liquid cannot be directed to the spray device. The direction of the piston mechanism is set to make the injection difficult.

Therefore, when the related type of the ejection device is in a horizontal state or a so-called various state, the liquid in the container can be ejected as in the normal state, and the prior art of Patent Document 3 is also mentioned, but This invention is characterized in that it is not suitable for a liquid ejector in a normal state by restricting the amount of liquid in the form of a so-called aerosol, that is, a piston in the field of dispensing liquid metering, which is decompressed in a container.

Disadvantages such as contaminated liquid containers and their surroundings, this creation provides no such Disadvantages of liquid injectors.

Still further, the related liquid ejecting apparatus provides that the liquid in the container is not ejected (including spraying, spraying) even when used in an upright state and of course in an inverted state (so-called various states including an almost horizontal state). And the liquid in the container does not leak out of the outside, providing an injector that can be used safely and with peace of mind.

Therefore, a first feature of the present invention is to provide a liquid ejecting apparatus comprising: a nozzle assembly, a nozzle assembly designed to eject an ejection port of a liquid at a front end of an upper portion of the liquid container; and a nozzle assembly to be connected to the liquid container a body of the liquid ejecting device extending from the cap, the body is provided with a piston mechanism for moving the liquid in the container to the nozzle assembly to move up and down, and the piston mechanism is formed as a phase of the upper end large diameter portion and the lower end small diameter portion The different diameter components constitute a step section, which is connected to the step section by the size component of the piston mechanism, and prevents the flat part of the piston assembly from moving up and down when the injector is not in use; and the horizontal sliding component is installed in the cap The body is provided with a concave portion at intervals in each horizontal direction, and the ejector can move the piston mechanism up and down in use; the above liquid ejecting device is provided.

Further, a vertical inverted dual-purpose operation assembly having a pair of vertical first passages and a second passage is formed at the piston mechanism; an upper end of the first passage is connected to an end of the piston mechanism, and a lower end is connected by a connecting passage. The end is connected to the upper end of the pipe of the aforementioned liquid, and in the connecting passage, a first ball valve having a diameter smaller than the inner diameter of the passage is inserted; before the end of the second passage is connected In the middle portion of the first passage, the upper end is open above the interior of the container, and the second passage is inserted with a second ball valve having a smaller diameter than the second passage. This is a second feature of the present invention.

Secondly, in the liquid ejecting device of the present invention, the result of the first feature is that when the state of use, storage, or display is not used, the aforementioned trigger lever is accidentally touched because the trigger of the trigger is Since the action is suppressed, the liquid in the container does not rise, so there is no risk of ejecting liquid or leaking liquid from the ejection port of the nozzle unit.

Further, the original ejector in which the horizontal sliding unit is mounted on the cap body is different from the mechanism in which the slewing unit that does not prevent the piston mechanism from moving up and down is installed, and the operation is smooth and can be performed by horizontal sliding of the correct operation. .

Further, the piston mechanism is moved up and down by the trigger of the trigger, and even when the liquid is ejected from the container, the horizontal slide assembly slides sideways, and the concave portion and the large-diameter portion of the piston mechanism are kept in a perpendicular straight line. A simple operation, the up and down movement caused by the trigger lever of the piston mechanism becomes free movement, and the up and down movement of the associated piston mechanism is guided by the concave portion, thereby reliably raising the liquid in the liquid container, that is, The liquid is ejected from the ejection opening of the nozzle assembly.

Moreover, the second feature of the liquid ejector of the present invention is that the piston mechanism is moved by the trigger of the trigger, and the contents of the liquid container connected to the ejection port are ejected by the liquid ejection opening of the ejection body.

[Implementation of the type of this creation]

One embodiment of the present invention is illustrated by a plate type liquid ejecting apparatus of the drawings.

(1) A liquid container such as shampoo is packaged, and the upper end is covered with a cap (2).

(3) A nozzle assembly mounted horizontally above the liquid container (1), having a liquid ejection port (4) for ejecting the liquid container (1) at one end, and a cap (2) attached to the other end at the other end Supports the upper end of the vertical piston mechanism (5) that moves up and down.

Therefore, the end of the piston mechanism (5) is connected to a liquid passage (22) to be described later. Further, in the figure, (6) the tie rod of the plate machine is formed into a pair of small "L" shapes lying on the front side, and the nozzle assembly (3) is clamped, and the upper side is designed on the upper surface of the nozzle assembly (3). At the end, the rear end portion pivotally engages the upper end of the support controller (7) projecting from the cap body (2).

However, this plate type liquid ejecting apparatus is a well-known general mechanism, and its detailed structural description is omitted. The main point is: by repeatedly performing the operation of "holding and releasing" the trigger of the trigger, the piston mechanism (5 The ball valve described later operates to suck up the liquid in the liquid container (1), and ejects it from the ejection port (4) to the outside using the nozzle assembly (3) as a medium.

In this embodiment alone, the piston mechanism (5) is vertical, the upper end is a large diameter (8) and the lower end is a small diameter (9), and a step portion (10) is formed at each joint portion.

Further, particularly in Fig. 2 and Fig. 3, (12) the upper end has a horizontal sliding assembly that is butted to the flat portion (13) of the step portion (10) of the piston mechanism (5); The support controller (7) of the aforementioned cap body (2) is slidably supported horizontally.

The length of the horizontal sliding assembly (12) is more than twice the diameter of the large diameter portion (8) of the piston mechanism (5), and at one side thereof, when in line with the large diameter portion (8), There is a top-shaped moon-shaped recess (14) for moving the piston mechanism (5) up and down, and a brim (15) is designed at both ends.

However, the present liquid ejecting apparatus body is now side-sliding to the flat portion (13) without the recess (14) when not in use for storage or handling or display or placement. Where the large diameter portion (8) and the small diameter portion (9) of the piston mechanism (5) are matched with each other in the section (10) where the section is made.

As a result, in the unused state of handling or storage or display, even if the aforementioned trigger lever (6) is accidentally touched, the trigger lever (the lever of the step section (10) and the horizontal slide assembly (12) The action of 6) is blocked, so that the liquid in the liquid container (1) cannot rise, and there is no possibility that liquid is ejected from the ejection opening of the nozzle unit (3).

Further, when the body of the liquid ejecting apparatus of the present invention is used, the concave portion (14) which slides the horizontal sliding unit (12) and the large-diameter portion (8) of the piston mechanism (5) are placed. Vertical straight line.

As a result, the piston mechanism (5) can freely move up and down by the trigger lever (6), so that the liquid in the liquid container (1) can be raised, and the liquid can be ejected from the ejection port of the nozzle assembly (3). .

Further, in the present invention, an embodiment of the ejector device in which the liquid in the container does not leak to the outside is used even in the upright or inverted state, and is shown in an enlarged explanatory view of Figs. 5 and 6 . That is, in the figure, (17) is an upright inverted dual-use operating assembly having a first pair of first passages (18) and a second passage (19).

In FIG. 5, the upper end of the first passage (18) is connected to the end of the piston mechanism (5), and then the lower end of the operating assembly (17) is connected by a horizontal passage (20) to connect a vertical connecting passage (21). The end is connected to the upper end of the liquid passage tube (22) disposed in the liquid container (1).

Then, a first ball valve (23) having a diameter smaller than the inner diameter of the connecting passage (21) is inserted into the connecting passage (21). Moreover, the upper end portion of the connecting passage (21) is provided with a recess (24), and when the first ball valve (23) is located above, the liquid in the liquid container (1) flows without causing trouble; and the connecting passage The lower end portion of (21) is inserted into the upper end portion of the passage tube (22) from the inner side, and the first ball valve (23) can form a close mating engagement with the upper end portion of the passage tube (22).

The end of the second passage (19) is connected to the middle portion of the first passage (18), and the upper end is open above the liquid container (1); and, in the second passage (19), the diameter is inserted. A second ball valve (25) that is smaller than the inner diameter of the second passage (19).

Furthermore, in the upper end portion of the second passage (19), the second ball valve (25) may It is installed at a first protruding portion (26) or the like that does not fly out of the liquid container (1); and, in a portion connected to the first passage (18), it can be installed not to the first passage (18) These designs are necessary for the second prominent department (27) that flies in the direction.

Further, the upper end portion of the second passage (19) is formed in a lattice shape (28), and when the second ball valve (25) is located at the upper end portion of the second passage (19), it must be designed to be in the liquid container (1). It is important that the liquid enters the second passage (19).

Further, when the conventional erect state is used, the trigger mechanism (5) is moved by the trigger lever (6), and the liquid in the liquid container (1) is connected from the passage pipe (22) to the passage (21). The first ball valve (23) is pushed up, from the periphery thereof, through the horizontal passage (20), enters the piston mechanism (5) through the first passage (18), is subjected to back-pressure, passes through the nozzle assembly (3), ejected from the injection port (4).

Furthermore, the liquid in the liquid container (1) in this case is forcibly directed toward the piston mechanism (5) due to the suction force of the piston mechanism (5); on the other hand, at the same time, the second passage ( The second ball valve (25) of 19) is located at the lower end of the second passage (19), blocking communication with the first passage (18) so that the associated liquid does not face the direction of the second passage (19).

Next, in the liquid container (1), the liquid container (1) of Fig. 6 is used at the upper end, that is, the injector body (16), and the lower end is used in a so-called upside-down state. The liquid does not remain at the bottom of the liquid container (1) but becomes a state of being accumulated toward the injector body (16) while being immersed from the lattice (28) of the second passage (19) to the second passage. (19) inside.

Here, if the piston mechanism (5) is moved by the trigger lever, the second passage is The liquid of (19) enters the living base mechanism (5) through the first passage (18), is back-pressured, passes through the nozzle assembly (3), and is ejected from the injection port (4).
