Description

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

"Problems to be Solved by Conventional Techniques and Inventions" As this type of container, a bottom wall member is fitted in a lower end portion of a tubular body member having upper and lower end surface openings in an airtight and ascendable manner, and a body member. Some upper end parts are provided with a pump device for discharging the creamy material filled in the body member. The pump device includes a cap-shaped member having a suction valve with the upper surface of the body closed, and a nozzle with a discharge valve that defines a pressurizing chamber (reservoir) between the cap-shaped member. It is composed of an upper covering member and a member with a lever for squeezing the elastic spherical wall of the upper covering member (see Japanese Utility Model Publication No. 61-147766 and Japanese Utility Model Publication No. 59-112772).

However, this type of container defines a pressurizing chamber (reservoir) that is controlled to open and close by a suction valve and a discharge valve at the upper end of the body member. However, there is room for causing malfunction of each function, for example.

A container has been proposed in which such a defect is eliminated and the structure is simplified except for the suction valve and the discharge valve (Shokai Sho 62-
See No. 60579).

In this container, an upper end opening of a cylindrical container body is closed by an elastic dome-shaped pumping member, and a lower end of a nozzle cylinder is slidably fitted to a cylindrical delivery port standing upright from the center of the pumping member. In addition, the tip is fixed to the upper end of the mounting head integrally provided on the upper end of the container body, and further, an operating lever for pivotally supporting the mounting head to openably and closably close the tip of the nozzle cylinder is configured. is doing.

However, since the container pivotally mounts the lever so as to be able to swing in the front-back direction, when the cover of the lever closes the tip of the nozzle cylinder after pouring the liquid, the container is rotated so as to slide on the upper end surface of the nozzle cylinder. There is a risk that the creamy material at the tip of the nozzle cylinder will be pushed downward.

Further, when the lever is operated, the rear portion of the upper surface thereof is pushed downward to be rotated, so that it is difficult to operate the lever with one hand holding the container.

The present invention solves the above-mentioned drawbacks of the prior art, and the dispensing operation with one hand holding the container is easy, the tip of the nozzle is not polluted, and the suction valve and the discharge valve are eliminated.
It is an object of the present invention to propose an excellent creamy substance pouring container which can simplify the structure of the liquid flow passage and prevent the contents from drying.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a container in which a guide cylinder 8 is erected from the center of a top plate 7 that closes the upper surface of a body 6 of a lower opening, and from the top surface of the top plate, A tubular body member 1 in which a support wall 9 is erected so as to surround the guide cylinder portion, a bottom wall member 2 fitted in the lower end portion of the body portion in an airtight and ascendable manner, and in the guide cylinder portion. A lower part of the nozzle cylinder 16 is vertically movably inserted, and the outer surface of the cylindrical piston 17 attached to the outer circumference of the lower end of the nozzle cylinder 16 is in sliding contact with the inner surface of the body, and the piston-equipped member 3 and the piston. A spring member 4 for urging the attaching member upward, and a refraction line 19 are provided in the middle portion of the rear wall portion of the U-shaped body 18 of the front opening fitted on the nozzle cylinder, and the middle portion of each side wall portion. Front and rear with respect to the lower half 18b of the U-shaped body The lower half of the lower half of the U-shaped body is pivotally attached to the rear edge of the support wall so as to be able to rotate forward, and is attached to the upper end of the upper half of the U-shaped body. It is composed of an operating member 5 in which the upper end opening of the nozzle cylinder is closed by an attached lid plate 22, and the first pin 23, 23 attached to the outer surface of both the left and right parts of the lower half of the nozzle cylinder 16 has the above-mentioned connector While engaging the lower end surface of the lower half of the U-shaped body so that the member with the piston can be pushed down, cutout grooves 24, 24 are provided sideways in both the left and right parts of the lower half of the U-shaped body. The left and right portions below the notch groove are elastically deformable plate portions 25, 25, and the second pins 26, 26 attached to the outer surfaces of both the left and right portions of the upper half of the U-shaped body are formed. When the front half of the U-shaped body is rotated forward, the upper half of the U-shaped body is rotated upward while the lower half of the U-shaped body is rotated upward in the cam holes 27, 27 attached to the left and right portions of the support wall. The lid plate so that it can be opened. Form was.

"Action" For example, from the state of FIG. 1, the lower half of the U-shaped body of the operating member 5
When 18b is rotated forward about the pivotal portion, the elastically deformable plate portion 25 elastically deforms in the initial stage of the rotation, and the rotational displacement in the lower end surface of the lower half of the U-shaped body is absorbed. That is, at this time, the member 3 with the piston is not pushed down. At the same time, due to the engagement of the second pins 26, 26 with the cam holes 27, 27, the upper half 18a of the U-shaped body rises upward and pivots rearward to open the lid plate 22 (Fig. 3). reference). At this time, since the lower half portion 18b of the U-shaped body is rotated by pushing the rear surface forward, it is possible to easily perform the pouring operation with one hand holding the container.

On the other hand, during the latter half of the rotation, the elastic deformation of the elastic deformation plate portion reaches the limit, whereby the member with piston 3 is pushed down against the urging force of the spring member 4 (see FIG. 4). As a result, the creamy material stored in the body portion 6 of the tubular body member 1 is pressurized, and the creamy material is poured out through the nozzle tube 16 to the outside.

When the rotation operation is released at the time when the creamy substance is poured out, the piston-equipped member 3 and the operation member return,
The inside of the body is negatively pressured, the bottom wall member 2 moves upward, and the lid plate closes. At this time, the upper half 18a of the U-shaped body
On the contrary to the case of opening the lid, the lid plate rotates forward while descending downward to close the tip of the nozzle cylinder, so that the creamy material at the tip of the nozzle is not pushed out of the nozzle.
