Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a container with a suction pump for a viscous liquid.

[Conventional technology]

Conventionally, as an example of a container with a suction pump of this kind,
A container with a suction pump described in Japanese Utility Model Publication No. 61-153772 is known.

As shown in FIG. 5, the upper end of the cylindrical body 1 is closed by the top plate 4, and the movable bottom cover 43 is slidably fitted into the lower end opening. , A suction hole 5 is provided, a first check valve 6 made of an elastic body is provided, and a tubular portion 50 is erected, and a cap-shaped pressing portion made of an elastic body in the tubular portion 50. 17 is attached to a cap, and a discharge hole 51 is further formed on one side of the tubular portion 50, and a discharge pipe 18 following the discharge hole 51 is provided.
Is provided upright on the top plate 4, and a second check valve 19 integral with the pressurizing portion 17 is provided in the discharge hole 51 portion.

Then, when the pressurizing portion 17 is pushed and then released, toothpaste or the like in the cylindrical body 1 is sucked into the pressurizing portion 17 through the suction hole 5, and when the pressurizing portion 17 is pushed again, the first check valve is released. 6 closed, second
The check valve 19 is opened and the toothpaste in the pressurizing section 17 is discharged from the discharge pipe 18. Then, as the amount of toothpaste in the cylindrical body 1 decreases, the movable bottom lid 43 rises due to negative pressure.

[Problems to be solved by the device]

The conventional container with a suction pump shown in FIG. 5 is convenient because the content liquid can be poured out with a relatively simple structure.

However, in the container with the suction pump, the movable bottom cover 43 may slide down to the lower end portion of the tubular body 1 during transportation, and further, the contents in the tubular body 1 may be removed.
There is a risk of leakage to the outside from between the movable bottom lid 43 and the movable bottom lid 43.

The present invention has been made in view of the above matters, and a technical object thereof is to provide a container with a suction pump in which there is no risk of the movable bottom lid slipping off and the contents do not leak.

[Means for solving the problem]

The container with a suction pump according to the present invention has a cylindrical body 1
And fixed to one end of the tubular body 1
A suction body including a pump body 15 for sucking the inside, a movable bottom lid 43 slidably fitted inside the tubular body 1, and a bottom cap 44 fixed to the other end of the tubular body 1. In the container with a pump, the movable bottom lid 43 is the cylindrical main body 1
Is located on the side of the bottom cap 44 with respect to the main body portion and has a smaller diameter than the inner diameter of the main body portion, and closes the space between the main body portion and the inner surface of the tubular body 1 to slide on the inner surface of the tubular body 1. Consisting of an annular sliding contact portion 40 in contact with the bottom cap 44,
The movable bottom cover 43 has a diameter smaller than the inner diameter of the annular sliding contact portion 40.
A cylindrical support member 47 having an outer diameter substantially the same as that of the main body portion and being longer in the axial direction than the step between the annular sliding contact portion 40 and the main body portion of the movable bottom cover 43. Characterize.

[Action]
