Description

Metered dispensing pump device preventable of water permeation

The present invention relates to a metered dispensing pump device capable of preventing the penetration of water. The device can be used in the container for inhaling and dispensing liquid in various containers. In particular, the present invention relates to the improvement of a metered dispensing pump device for sucking liquid from a container with a hand wash cream, hair shampoo or shower gel for use in a bath. The liquid in the vessel can be protected from infiltration and contamination by showering water with the device. And, the stability and quality of the chemical liquid in the vessel can be maintained well.

As is known, containers filled with common chemical liquids, such as hand wash creams, hair shampoos or shower gels, etc., have a dispense pump device that is metered for the user to press for suction of a chemical liquid amount. Containers filled with common chemical liquids, such as hand wash creams, hair shampoos, or shower gels, may be placed under water in a showered environment, such as in a bathroom, to allow the user to obtain and pressurize the chemical liquid to wash the hair or body. Is located in the spot. However, conventional metered dispensing pump devices (such as shown in FIG. 1), which are placed in a water-filled environment and mounted on a bottle filled with a common wash solution (as shown in FIG. 1), are not waterproof, and water often penetrates into the container and causes It affects quality.

In a conventional metered dispensing pump device as shown, for example, in FIG. 1, when the user presses the liquid discharge knob 1, the piston 22 in the liquid storage pipe 2 filled with liquid becomes liquid. The liquid in the storage pipe 2 is pressed down to approach the piped sheet 4 in order to push the steel beads 21 apart. Thereby, the liquid is discharged from the container 10 through the liquid discharge knob 1, and the purpose of taking the liquid in a simple manner can be obtained. Then, by stretching and compressing the spring 23, the piston 22 and the pipe 2 are pressurized upward for suction, and air is drawn from the wall in the groove 31 of the cap 3 and the liquid storage pipe ( It can be obtained through the air path 33 formed between the 2) and the annular portion 32 which is positioned to release the vacuum state of the container 10. Thereby, the liquid in the vessel 10 can be pushed apart to suitably space the steel beads 41 in the liquid supply pipe 42 to refill the pipe 2.

Nevertheless, the conventional metered dispensing pump apparatus described above may have a groove 31 of the apparatus for receiving a liquid release knob 1 that accumulates with bath water when showering. When the liquid release knob 1 is pressurized, the bath water accumulated in the groove 31 will be obtained by positioning the annular portion 32 and the air path 33 into the container 10. This causes fouling of the liquid in the container 10, dilution of the water therein, and the growth of bacteria therein that can rot or worsen the liquid. This problem mainly arises from an air path 33 formed between the wall in the groove 31 of the cap 3 and the opening in the liquid storage pipe 2 and the downward opening in the container 10 (see FIG. 1). Shown). Thus, it is an object of the present invention to solve this problem.

In view of the above-mentioned problems of liquid contamination and deterioration in the container, the main purpose of the present invention is to provide a means of pressurizing the metered dispensing pump device through an air path formed between the wall in the groove and the liquid storage pipe of the device. It is to prevent the penetration of water into the container. Thus, the purpose of protecting the liquid in the container from contamination of external bath water can be obtained.

To achieve this object, the circumferential wall of the liquid storage pipe can be changed to have a slope, and an inclined pipe having a pipe mouth larger than the cap is provided. Thereby, the inclined liquid storage pipe can be connected in close contact with the higher pipe mouth of the tapered pipe prior to pressurizing the metering dispensing pump device to prevent water from penetrating and forming an air path after pressurization. can do. The air path is formed at a larger position than the groove exposed to the accumulation of water, so that the bath water accumulated in the groove will not penetrate into the container. And the chemical quality of the cleaning liquid in the container can be protected.

The present invention will be better understood from the detailed description of the preferred embodiments with reference to the attached drawings.

51 liquid discharge pipe 62 threaded portion

2 and 3, the metering dispensing pump apparatus capable of preventing the penetration of water of the present invention is mainly a liquid discharge cover 5, a cap 6, a liquid storage pipe 7, and a liquid intake valve ( 71, a container cap 93, a spring 75, a valve membrane 8, and a pipe-like seat 9.

Here, the liquid discharge cover 5 has a liquid discharge pipe 51 and includes a sleeve 50 having a smaller diameter and an outer thread pipe 52 having a larger diameter (shown in FIG. 5). Is provided at the center bottom. The sleeve 50 and the liquid discharge pipe 51 are in communication with each other to form a liquid discharge channel. The liquid storage pipe 7 is connected to the sleeve 50 for supplying the washing liquid to the liquid discharge pipe 51 of the liquid discharge cover 5. The outer threaded pipe 52 of the liquid discharge cover 5 is locked to the threaded portion 62 of the cap 6, whereby the liquid storage pipe 7 originally exposed to the space above the cap 6 (FIG. 5). Shown) is limited. That is, the liquid discharge cover 5 is locked in the cap 6 after it is pressed down to hide the liquid storage pipe 7 so that the liquid discharge cover 5 and the liquid storage pipe 7 are raised. And exposure (shown in FIG. 4). Thus the shape of the entire container is reduced for good packaging and shipping.

The cap 6 is made in its entirety, one end of which has a tapered pipe 61 and a threaded portion 62, while the other end thereof has a mouth 63 and an internal threaded portion 64 ( Shown in FIG. 4). The groove is formed by the threaded portion 62 and sealed at the bottom thereof. The mouse of the tapered pipe 61 is made larger than the cap 6 to have a height difference 'h' (refer to FIG. 5). The tapered pipe 61 is in communication with the mouse 63. The mouse 62 is locked to match the outer thread pipe 52 of the liquid discharge cover 5 so that the outer thread pipe can be locked to the cap 6. The mouse 63 may be connected to one end of the liquid storage pipe 7. The inner thread 64 can be locked onto the threaded portion 95 on the pipe-like sheet 9.

The circumferential wall of the liquid storage pipe 7 has a slope α (this is also shown in FIG. 5). One end of the liquid storage pipe 7 can be connected with the mouth 63 of the cap 6, the other end of which has a valve port 72 for mounting the liquid intake valve 71.

The liquid intake valve 71 consists of a valve plug 74 and a valve sleeve 73 assembled with it (shown in FIG. 3). The valve plug 74 is mounted on one end with a spring 75 and provided on the other end with a liquid guide plate 741 of an intersecting shape. The liquid guide plate 741 may be connected to the valve port 72 of the liquid storage pipe 7 after sliding on the valve sleeve 73. Thus, the valve sleeve 73 can be freely moved upward and downward relative to the liquid guide plate 741 to open and close the control valve for the cleaning liquid. And this (as shown in FIGS. 5 and 6) can replace the release beads.

The valve membrane 8 is made entirely of PP and has an internal C-shaped ring (as shown in FIG. 3). The valve membrane 8 is located in the horizontal wall section 96 of the piped seat 9 so that it acts as a one-way shank valve only for discharging the cleaning liquid from the vessel (shown in FIGS. 5 and 6). As shown).

The piped sheet 9 is provided at one end with a peripheral flange 91 and a threaded portion 95, while the other end thereof has a liquid supply pipe 92. A number of air holes 94 are provided below the peripheral flange 91. The horizontal wall section 96 is provided between the piped section 9 and the liquid supply pipe 92 (as shown in FIG. 4). Here, the peripheral wall 91 may be fixed on the container mouse 100 on the top of the container 10 by rotational locking of the container cap 93 with the washer 931. The threaded portion 95 can be matched with the internal threaded portion 64 of the cap 6. The pipe seat 9 is mounted therein with a liquid storage pipe 7 and a liquid intake valve 7 so that the spring 75 of the liquid intake valve 71 can make the valve membrane 8 compact. . As such, the valve membrane 8 can be elastically and firmly pressed onto the wall section 96 having a reduced diameter (as shown in FIG. 5).

By assembling the above-described member, the metering dispensing pump apparatus of the present invention can be constructed. The peripheral flange 91 of the pipe-like sheet 9 is mounted on the container mouse 100 on top of the container 10, locked with the container cap 93, and then the washer 931 is attached to the container mouse 100. ) Can be hermetically contacted with the container mouse to seal it entirely.

In use, the liquid dispensing cover 5 is released (as shown in FIG. 5). And, when the liquid dispensing cover 5 is separated from the threaded portion 62 of the cap 6, the liquid suction valve 71 springs 75 to elastically lift the liquid storage pipe 7. ) Can be pushed upwards. The tapered wall around the liquid storage pipe 7 is in contact with the tapered pipe 61 of the cap 6 so that the external bath water is brought into the container 10 even if it is showered directly in the liquid storage pipe 7. It cannot penetrate. Thereby, the effect of preventing the penetration of water into the vessel 10 can be achieved. When the liquid intake valve 71 moves upwards, the valve sleeve 73 and the valve plug 74 are pipe-like seats 9 to form a vacuum intake structure for withdrawing liquid from the vessel 10. It comes into close contact with the inner wall of the. Thereby, the liquid in the vessel 10 flows through the liquid supply pipe 92 to raise the valve membrane 8 and thus enters the pipe-like seat 9. When the spring 95 is fully stretched to raise the liquid storage pipe 7 and comes into intimate contact with the tapered pipe 61 of the cap 6, the valve membrane 8 causes the weight of the liquid to rise. The stop of over suction causes close contact with the horizontal wall section 96. Thereby, a sealed state is formed, and the pipe-like sheet 9 is usefully filled by the user with a predetermined amount of liquid from the container 10 in order to be pressurized. This is a ready state in which the metering dispensing pump device is in a steady state when not yet pressurized.

When the liquid dispensing cover 5 is pressed down to fill the liquid of the container 10 (as shown in FIG. 6), the liquid storage pipe 7 presses the spring 75 and the predetermined amount It is pressurized to carry the liquid suction valve 71 down in order to extrude the liquid. The valve sleeve 73 then moves upward to form a liquid discharge annular gap 76 between itself and the valve plug 74, and the tapered pipe 61 and the peripheral wall of the liquid storage pipe 7. The inclination α of the mouse of) is gradually separated to form the annular gap 60. The annular gap 60, the air hole 94, and the plurality of surrounding holes of the washer 931 form an air path 65 to communicate the interior and exterior of the container 10. Thereby, air can enter the container 10 via the air path 65 to prevent the formation of a vacuum state introduced by suction, and taking liquid from the container 10 can be smoothed. In this mode, even when the thread 62 accumulates in the bath water in the shower, the bath water is blocked by the outer wall of the tapered pipe 61 and the height difference between the cap 6 and the tapered pipe 61. is separated from the air path 65 by 'h'. In this way, the problem of the bath water flowing into the container 10 and contaminating the liquid therein can be solved, and the penetration of water can be prevented.

When the valve membrane 8 approaches in close contact with the horizontal wall section 96 due to the stop of suction and the weight of the liquid, a predetermined amount of liquid crosses the liquid distribution annular gap 76 and the liquid guide plate in the cross shape. And flows through 741. The liquid introduction of the cross-shaped liquid guide plate 741 introduces a predetermined amount of liquid into the liquid storage pipe 7 and discharges it out of the container 10 through the liquid discharge pipe 51. Thereby, taking the liquid from the container 10 becomes effective (as shown in FIG. 6).

When the pressure of the liquid storage cover 5 is removed, when the liquid intake valve 71 is raised by the spring 75, the liquid intake valve 71 is raised by the spring 75, the container ( The liquid storage pipe 7 is resiliently moved upward to re-form the vacuum to withdraw the liquid from 10). With the aid of an air path 65 in communication with the outside atmosphere, the liquid withdrawn from the vessel 10 raises the valve membrane 8 and so for the liquid supply pipe 92 to enter the piped seat 9. Is provided. The pipe-like sheet 9 is refilled from the container 10 to a predetermined amount of liquid and is ready to be pressurized to withdraw the liquid.

In conclusion, the metering dispensing pump device capable of preventing the water penetration of the present invention can effectively prevent the ingress of external bath water into the container 10 by the water stop of the tapered pipe 61 of the cap 6, The liquid in the vessel 10 can be protected from contamination of the bath water.

As such, the technical configuration of the present invention has feasibility and improvement.
