Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a cream-like material dispensing container for dispensing cream-like material under pressure.

``Prior Art'' The present applicant first depresses the elastic dome forming the top wall of the cream storage chamber, and the discharge valve opens due to the high pressure inside the cream storage chamber. The cream inside the chamber is poured out from the nozzle to the outside, and when the elastic dome is released, the pressure inside the cream storage chamber becomes negative, the suction valve opens, and the cream is poured out from the body of the container. An application was filed for a device that allowed cream-like substances to be sucked up and replenished into the storage chamber (utility model registration application filed in 1985).
No. 36609).

"Problems to be Solved by the Invention" The dispensing container according to the above-mentioned application had a drawback that the liquid did not drain easily and the area around the nozzle became dirty.

In this proposal, a booth is formed in the discharge valve, and by utilizing the negative pressure in the cream storage chamber due to the elastic restoration of the elastic dome, some of the cream inside the nozzle is sucked back into the storage chamber from the booth. It is designed to eliminate the above-mentioned drawbacks.

"Means for Solving the Problems" A first top wall 3 having a through hole 4 with a suction valve 6 is formed on the upper inner surface of the lower end face opening body 2, and a first top wall 3 having a through hole 4 with a suction valve 6 is formed surrounding the suction valve 6. The main member 1 has a notch 8 formed in the front surface of the peripheral wall 7 for forming a cream storage chamber that stands up from the top wall 3, and the outer cylinder part 12 that hangs down from the second top wall is fitted to the upper part of the body part. At the same time, the inner cylindrical part 14 is suspended from the lower edge of the elastic dome 13 formed by raising a part of the second top wall into a hemispherical shape, and is attached to the outer surface of the cream-like substance storage chamber forming peripheral wall 7. The left and right sides of the front part of the inner cylinder are separated, and the discharge valve 15 is formed by using the elastic valve body 15a to form the discharge valve 15 which can open and close the notch 8 freely. From other parts, a cap member 11 having an upright nozzle 20 communicating with the suction valve 6 via a discharge valve 15, and an inner plate 21 fitted airtightly and movably into the lower end of the body 2. The discharge valve 15 is provided with a small gap 16 for sucking back the creamy substance remaining in the nozzle.

"Operation" When the closing member 22 is removed from the state shown in FIG. Due to the negative pressure in the cream storage chamber A formed by the storage chamber forming peripheral wall 7 and the first top wall 3 of the main member, the suction valve 6 opens and the discharge valve 15 closes, so that the cream The cream-like substance in the main member body 2 is sucked up into the storage chamber A through the through hole 4. When the elastic dome is pushed down again in this state, the suction valve 6 closes and the discharge valve 15 opens due to the high pressure inside the cream storage chamber A, causing the cream inside the cream storage chamber A to flow into the notch. 8 through nozzle 20
is poured out to the outside. Next, when the pressing of the elastic dome is released, the negative pressure inside the cream storage chamber A causes the cream inside the main member body 2 to pass through the through hole 4 as described above. At the same time, the creamy substance remaining in the nozzle is sucked back into the creamy substance storage chamber A through the booth 16 provided in the discharge valve. In addition, as the creamy substance inside the main member body decreases, the inner plate 21
As the pressure rises, negative pressure inside the body is prevented, and the creamy substance is always guided upwards in the body.

``Example'' The cream dispensing container of the present invention is composed of a main member 1, a cap member 11, and an inner tray 21.

The main member 1 has a first top wall 3 formed on the upper inner surface of a body part 2 with an open lower end surface, and a short cylindrical part is erected from the periphery of a through hole 4 made in the first top wall. death,
And the mounting cylinder 5 is erected from the upper surface of the first top wall with a space between it and the short cylinder part, and inside the mounting cylinder,
A suction valve 6 that freely opens and closes the through hole 4 is fitted inside. The suction valve is constructed by cutting off the bottom wall of a cylinder 6a fitted into the mounting cylinder 5 into a tongue shape, leaving a part intact, and using the separated part as a valve body 6b. Further, surrounding the suction valve, a cream storage chamber forming peripheral wall 7 is made to stand up from the first top wall 3, and a notch 8 is formed in the front surface of the peripheral wall. Further, as shown in FIG. 2, the rear portion of the peripheral wall may be used in common with the wall portion of the body, and grooves 9, 9 are formed on both left and right portions of the common portion. Furthermore, the connecting cylinder 10 is made to stand up from the front upper surface of the first top wall 3. The connecting cylinder shares its front wall with the trunk wall, and has an open rear part, with both left and right ends of the opening in watertight pressure contact with the outer surface of the inner cylinder of the cap member, which will be described later. .

The cap member 11 has an outer cylinder part 12 fitted to the upper part of the body part 2 and suspended from a second top wall, and a part of the second top wall is raised in a hemispherical shape to form an elastic dome 13. None, the inner cylindrical part 14 hanging from the lower edge of the elastic dome is airtightly fitted to the outer surface of the cream storage chamber forming peripheral wall 7, and the elastic dome 13, the cream storage chamber forming peripheral wall 7 and the main The first top wall 3 of the member forms a cream reservoir A. Further, the inner cylinder portion 14 is fitted by using the grooves 9, 9 so as to straddle the body portion of the main member. or,
The front part of the inner cylindrical part 14 is separated to the left and right, and this part is used as an elastic valve body 15a to form a discharge valve 15 that closes the cutout part 8 so as to be openable and closable. The discharge valve has a booth〓
16 is formed so that the cream-like material remaining in the nozzle, which will be described later, can be sucked back at the end of dispensing. As shown in FIGS. 3a and 3b, the booth 1 may be formed by vertically providing a protrusion 17 on the outer surface of the cream storage chamber forming peripheral wall 7 below the notch 8. As shown in Figures a and b, it may be formed by drilling a long hole 18 in the lower part of the elastic valve body 15a. It may be provided by forming long grooves 19 on the outer surface of the peripheral wall 7 for forming a shaped material storage chamber and on the lower inner surface of the elastic valve body 15a, respectively. Further, from the other part of the second top wall, the nozzle 20
is erected and communicated with the suction valve 6 via the connecting cylinder 10 and the discharge valve 15.

The inner plate 21 is fitted into the lower end of the body 2 airtightly and so as to be able to rise.

Reference numeral 22 denotes a closing member in which a plug portion 23 is fitted into the nozzle 20.

``Effect of the invention'' The present invention has the above-mentioned structure, and the discharge valve is formed with a booth 16, and by utilizing the negative pressure in the cream storage chamber due to the elastic restoration of the elastic dome, the booth 16 is created. Since the cream material in the nozzle is sucked back into the storage chamber, the liquid drains well and the area around the nozzle does not get dirty.
Further, the structure is simple and can be formed at low cost.
