Description

[Detailed Description of the Invention] "Industrial field of application" The present invention relates to a creamy substance dispensing device for dispensing a stored creamy substance under pressure.

"Problems to be solved by conventional techniques and devices" In this type of container, a small manual pump in which a piston is constantly pushed upward by a return spring at the top of a cylindrical container body,
It has a discharge valve with a discharge valve for pushing down the piston, and a suction valve, and presses down the discharge cylinder to pressurize the cream-like substance in the pump. The valve is opened and poured out from the pouring cylinder, while the negative pressure inside the pump due to this pouring causes the suction valve to be opened, and the creamy substance is sucked into the pump from the body of the container and replenished. There is something to prepare for the next pouring.

The piston has a structure in which it is pressed against the inner surface of the cylinder through a cylindrical elastic peripheral wall, so an external force is required for the pressing operation, and a small lid that closes the spout at the tip of the spout is poured out. It is opened and closed by hand every time.

The idea is to attach a push-down lever that pushes down the spout barrel to this type of container, so that the piston can be pushed down easily, and the tip of the spout barrel can be linked with the operation of the push-down lever. By attaching a small lid that opens and closes the spout to the tip of the push-out cylinder of the push-down lever, it is possible to eliminate the complexity of manually opening and closing the small lid each time it is poured.

"Means for Solving the Problems" A cylinder 9 is erected from an inner surface of an upper portion of a tubular body 6 through an inward flange-shaped wall, and a flat cross-shaped support portion 7 is provided on an inner surface of a lower end of the cylinder. The main body 1 in which the bottom plate 11 with the detent 10 is fitted to the inner surface of the lower part of the body 6 so as to be slidable upward, and the lower part of the peripheral wall 26 is fitted to the outer surface of the upper part of the body 6, and the peripheral wall A window in the latter half of the top wall 12 formed at the upper end
13 is opened greatly, the front wall 32 is erected from the front edge of the window,
In addition, in the front half of the top wall 12, an inverted L-shaped pouring tube 14 in which a vertical tube portion 14a is located at the center of the cylinder 9 is provided through a horizontal tube portion 14b. A cap-shaped member 2 in which engaging pieces 15 and 15 are hung from the lower surface of the top wall 12 of the above, and an upward circumferential groove 17 into which the vertical cylindrical portion 14b is inserted near the inner circumference of a thick cylindrical portion 16; A downward circumferential groove 18 is formed near the outer periphery of the portion 16, and an elastic peripheral wall 19 attached to the lower outer surface of the tubular portion 16 is fitted to the upper inner surface of the cylinder 9, and the liftable piston member 3 and the support portion 7 And a return spring 4 interposed between the top wall of the downward circumferential groove 18 and biasing the piston member 3 upward, and the window.
Side plate parts are hung vertically from the left and right edges of the pressing plate part 20 that is arranged to be able to be pushed down to the front side, and the bent parts 21, 21 of the front end part are provided with the engaging pieces 15, 15 engaging plate portions 22, 22 engaging with the lower end are projected forward, and the vertical projections 23, 23 attached to the inner surface of the front part of the side plate portion are brought into contact with the upper left and right parts of the upper end of the tubular portion 16, Further, a lid plate 24a that closes the spout at the tip of the spout tube 14 from the front end edge of the plate portion 24 projecting forward from the front end of the pressing plate portion 20 via the thin hinge 25, and the left and right side edges of the plate portion The engaging plate portions 24b, 24b are respectively hung from the above portions, and the push-down levers 5 are engaged with the rear ends of the engaging plate portions 24b, 24b to the front surface of the front wall 32. , 23 Lower end and pressing plate 2
0 The distance between the rear end and the lower end of the engaging pieces 15,15 and the vertical projections 23,23
It was set longer than the distance from the bottom edge.

[Operation] As described above, the piston member 3 is normally pushed up to the upper limit position by the return spring 4, and the creamy substance is filled in the cylinder 9 as shown in FIG. 1b. The lid plate 24a closes the spout at the tip of the spout cylinder 14.

In this state, if the piston member 3 is pushed down against the elasticity of the return spring 4 by pushing down the rear end portion of the pressing plate portion 20, the stored cream-like substance is pressed and, at the same time, the pressing plate portion 20 is lowered. The part of the push-down lever 5 in front of the thin hinge 25 is shown in FIG.
As in a and b, the thin hinge 25 stands upright to open the spout at the tip of the spout tube 14, so that the creamy substance is spouted from the spout tube 14.

When the pushing operation is stopped at the time when the pouring of the creamy substance is completed, the inside of the cylinder 9 becomes a negative pressure, so that the creamy substance in the body 6 is sucked up into the cylinder 9, and by this suctioning Since the inside of 6 becomes negative pressure, the bottom plate 11 moves upward.

Therefore, the distance between the lower ends of the vertical protrusions 23, 23 and the rear end of the pressing plate portion 20, that is, the distance between the point of action and the point of force is determined by the lower ends of the engaging pieces 15, 15 of the cap-shaped member 2 and the vertical protrusion. Since the distance between the lower ends of the strips 23, 23, that is, the distance between the fulcrum and the point of action is longer, the lever operation makes the pushing operation lighter and easier.
