no. 1 Embodiment

[0068] figure 2 Showing the first embodiment of the present invention, it is an enlarged view of a valve sealing body with an inclined bottom surface, wherein (A) is a cross-sectional view and (B) is a plan view.

[0069] When the liquid discharge device is not in use, the valve sealing body 51A is coupled to the valve seat 51 through the thin wall portion 51A1 surrounding the outer periphery and the hinge portion 51A2 to close the opening of the valve seat 51 .

[0070] In this embodiment, the bottom surface of the valve sealing body 51A is inclined so that the hinge part side part P is downward and the opposite end Q is upward, and the wall is thicker at the P part and gradually becomes thinner toward the opposite end Q.

[0071] The enlarged view of the valve sealing body formed in this way in the state where the front end of the valve is pushed up is shown in Fig. image 3 Shows.

[0072] When the piston descends, the front end 8A of the valve is relatively pushed up, f...

no. 2 Embodiment

[0081] The inclination of the bottom surface of the valve sealing body can also be realized by inclining the entire valve sealing body.

[0082] Figure 5 An enlarged view showing a valve seal formed integrally inclined.

[0083] In this embodiment, the opening of the valve seat 51 including the valve sealing body 51A is formed in an inclined shape as a whole.

[0084] The hinge portion 51A2 is formed to connect the lowermost end of the valve seat 51 and the lowermost end portion P of the valve sealing body 51A.

[0085] The valve sealing body 51A has a constant thickness, and its bottom surface is gradually inclined upwardly from the lowermost end portion P toward the opposite end Q. As shown in FIG.

[0086] Incidentally, the thickness of the valve sealing body 51A does not have to be constant, and can be changed as appropriate.

[0087] With the valve sealing body formed in this way, as in the first embodiment, the front end of the valve is accurately guided to the oppos...

no. 3 Embodiment

[0089] The object of the present invention is to reliably break the thin-walled portion of the valve sealing body from a distance from the hinge portion, that is, from the vicinity of the opposite end.

[0090] As with the previous embodiments, it is not necessarily necessary that the front end of the valve push up on the opposite end itself, it can also be achieved by being arranged to push up as close as possible to the opposite end.

[0091] That is, a recess may be provided near the opposite end, and the front end of the valve may be guided to the recess.

[0092] Image 6 (A) is a cross-sectional view, and (B) is a plan view, which is an enlarged view showing a valve sealing body provided with a concave portion near the opposite end.

[0093] With this form, the front end of the valve inside the sleeve is reliably caught and stopped in the recess R. As shown in FIG.

[0094] Then, when the front end portion urges the concave portion R, it can be reliably broken from the...

Abstract

The present invention discloses a liquid discharging device. Via the altering of valve sealing body, the front end of the valve in the sleeve is made to break the thin wall part of the valve sealing body and the valve sealing body is made to break from the opening of valve seat. The liquid discharging device has nozzle, which may be mounted to the cap of the container mouth in the mode of moving up and down synchronously with the piston to discharge liquid from the container. The sealing body capable of being isolated by pushing upwards the front end of valve in the sleeve mounted in the cap is set on the valve seat formed on the piston, and the valve sealing body has its bottom which is inclined owing to the action of the inclined weight.

Description

technical field [0001] The present invention relates to a liquid discharge device such as a pump type, which can realize the ejection of high-viscosity liquid such as shampoo or the ejection and spraying of low-viscosity liquid such as lotion by manual operation. The valve seal that disconnects from the valve seat and the initial seal that keeps the device in its unused condition. Background technique [0002] The pump-based liquid discharge device has several measures to prevent the liquid in the container from being accidentally ejected from the nozzle during transportation before use, etc. [0003] The most common of these measures is to immobilize the spray head. The fixing means is roughly divided into two types: temporary fixing at the bottom dead center position where the nozzle head is lowered to the lowest position, and temporary fixing at the top dead center position (upper dead center) where the nozzle is not depressed at all. [0004] Among...
