Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a creamy substance dispensing container for dispensing a stored creamy substance under pressure.

[0002]

[Prior art]

 This type of container has a small manual pump at the top of which a piston is constantly pushed upward by a return spring, an operating member for pushing down the piston, and a suction valve and a discharge valve. The creamy material inside the pump was pressurized by pressing down, and the discharge valve was opened by this pressurized creamy material and poured out to the outside, while the inside of the pump became negative pressure by this pouring. There is one that opens the suction valve at, and sucks the creamy substance from the container body to the pump to replenish it and prepare for the next pouring.

[0003]

[Problems to be solved by the device]

 Conventionally, this kind of container has a large number of parts, and there has been a restriction on cost reduction. For example, the push-down lever, suction valve, and discharge valve are independent parts, and the piston is also a separate part.

The present invention is to obtain a creamy substance dispensing container in which the number of parts can be reduced as much as possible, and thus cost can be reduced.

[0005]

[Means for Solving the Problems]

 A main body 1 in which a sliding cylinder 10 is pierced from the center of a top plate 9 of a straight cylindrical container body 8 and a mounting peripheral wall 11 is erected from the peripheral portion, and a cap-shaped top plate. The center strip of 12 in the front-rear direction is partially cut out to form a push-down lever 13, and a cylindrical piston 14 whose lower end is internally press-fitted to the sliding cylinder 10 is hung from the rear surface of this lever 13 and An operating member 2 fixedly mounted on the mounting peripheral wall 11 and a push-down lever 13 are constantly pushed upward by penetrating a pouring cylinder 15 communicating with the cylindrical piston 14 and opening to the outside. A return spring 3 which is biased upwardly, a bottom plate 4 which is fitted in the container body 8 in an airtight manner and vertically slidable, and a bottom plate 4 which is attached to the lower surface of the bottom plate 4 and is reversely pierced on the inner wall surface of the body 8. A detent member 5 for preventing the bottom plate 4 from descending and a stopper 6 for closing the opening of the pouring cylinder 15 are formed.

[0006]

[Action]

 As described above, the movable portion of the operating member 2, that is, the push-down lever 13, the cylindrical piston 14, and the spouting cylinder 15 are normally pushed upward by the return spring 3 and are urged upward. Is filled up to the inside of the spout barrel 15.

In this state, when the movable portion is pushed down by the push-down lever 13 against the return spring 3, the creamy substance in the inner portion is pressurized and poured out from the pouring tube 15 to the outside.

When the pushing operation is stopped when the creamy substance is substantially poured out, the movable part returns to the original state shown in the drawing by the return spring 3, and the pouring cylinder 15, the cylindrical piston 14 and the sliding cylinder 10 are returned. Since the inside has a negative pressure, the creamy substance in the body 8 is sucked upward, and the suction causes the inside of the body 8 to become a negative pressure, whereby the bottom plate 4 moves upward together with the detent member 5. .

[0009]

【Example】

 The creamy substance dispensing container of the present invention comprises 6 parts of a main body 1, an operating member 2, a return spring 3, a bottom plate 4, a detent member 5 and a spigot 6, except for the return spring 3 and the detent member 5. Each part is molded and made of synthetic resin material.

First Embodiment (FIGS. 1 and 2)

In the main body 1, a sliding cylinder 10 is erected from the center of the top plate 9 at the upper end of the body 8 having a straight tube shape, a mounting peripheral wall 11 is erected from near the periphery, and the lower end of the body 8 is It has an expanded shape. A thin portion 16 is formed around the base end of the sliding cylinder 10.The sliding cylinder 10 can be swung with the thin portion 16 as a base point for the reason described later, and an engaging protrusion 17 is provided on the mounting peripheral wall 11. It is protruding.

The operation member 2 has a cap-like shape, and the press lever 13 is formed by making a notch in the other part, leaving the front part with the thin hinge 18 at the front-rear center band of the top plate 12. From the back surface of the push-down lever 13, a straight-cylindrical cylindrical piston 14 whose lower end elastic skirt portion 19 is internally press-contacted with the inner wall surface of the sliding cylinder 10 hangs down, and communicates with one upper side of the cylindrical piston 14. Then, a small-diameter spouting cylinder 15 that opens slightly obliquely upward on the front side is installed horizontally, and the engaging groove on the inner surface of the lower portion of the peripheral wall 20 is engaged with the engaging ridge 17 to attach the outer surface of the peripheral wall 11 for mounting. It is fitted and attached to. A window 21 is opened in the center of the rear side of the push-down lever 13, and an edge 22 of the window 21 is locked to a stopper 23 formed by bending the upper end of the rear side of the peripheral wall 20 inward so that the state shown in the figure is obtained. Hold it. Reference numeral 24 denotes a spring receiver that supports the upper end of the return spring 3 on the rear side.

In the operating member 2, the push-down lever 13, the tubular piston 14, and the pouring barrel 15 are integrated, and therefore, when these parts are lowered during the push-down, they are vertically rotated about the thin hinge 18 as a fulcrum. As a result, the elastic skirt portion 19 comes into partial contact with the sliding cylinder 10 and is partially consumed to shorten the life. Therefore, the sliding cylinder 10 can be swung so as to absorb the rotating operation.

The return spring 3 is in the form of a coil, and surrounds the cylindrical piston 14, and is inserted between the back surface of the operating member 2 and the intermediate portion of the outer surface of the sliding cylinder 10.

In the bottom plate, an elastic peripheral wall 25 having an arcuate cross section is pressed against the inner wall surface of the body 8 and is fitted in the body 8 in an airtight and sliding manner.

The detent member 5 has a plurality of claws 27 which are inserted in and fixed to the lower surface of the bottom plate 4 from the base plate 26 and which are pierced against the inner wall surface of the body 8 in the radial direction. Since it moves up but does not descend, the bottom tray 4 can be prevented from descending when the push-down lever 13 is pushed down without providing a check valve function suction valve, and the pouring function is not hindered.

The spout 6 is a small cap with a knob, and is externally fitted and attached to the opening of the spout barrel 15.

Although the cap 7 is externally fitted and attached to the peripheral wall 20 of the operation member 2 by screwing or the like, it may not be necessarily provided.

Second embodiment (FIGS. 3 and 4)

In this embodiment, the cylindrical piston 14 is a separate member independent of the operating member 2, and therefore the number of parts is increased by one. Structurally, the upper end of the sliding cylinder 10 of the main body 1 is reduced in diameter to form a guide cylinder 28, while the cylindrical piston 14 is provided with an outward flange at the lower end, and the sliding cylinder is provided on the outer peripheral edge of this flange. 10. An elastic peripheral wall 29 having an arcuate cross section is formed in pressure contact with the inner wall surface. Therefore, since the guide cylinder 28 portion functions as a stopper for the movable portion, the stopper 23 and the window 21 in the first embodiment are omitted. Also in the second embodiment, since the push-down lever 13, the tubular piston 14 and the pouring cylinder 15 are integrally structured, like the first embodiment, these parts descend at the time of pushing down and at the same time the thin hinge 18 serves as a fulcrum. By rotating in the vertical direction, the elastic peripheral wall 29 of the cylindrical piston 14 is partially hit. Therefore, a split groove is formed in the upper part of the front side of the peripheral wall 20 from the hinge 18 to the middle part, and the split groove 30 is opened to the left and right when pushing down to absorb the rotation. Further, although the discharge valve 31 is provided at the upper end opening of the cylindrical piston 14, this may not be provided.

[0021]

[Effect of device]

 As described above, in the present invention, since the detent member 5 is provided, the suction valve is not necessary, and the discharge valve 31 is not always necessary. Further, the push-down lever 13, the cylindrical piston 14, and the movable pouring cylinder are not necessary. Since 15 is formed as a single member as the operating member 2, the number of parts can be reduced as compared with the conventional one, so that the cost can be reduced, and since the number of parts is reduced, the operation reliability is also improved.
