Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a creamy material dispensing container.

"Problems to be Solved by Conventional Techniques and Inventions" As a cream-like material discharging container, for example, a cylindrical container having an open lower surface and an upper surface closed by a top wall, and a lower surface of the container airtightly closed. The cream-like material in the container is discharged from the tip of the nozzle by using the pressure of the elastic dome through the movable bottom plate fitted and slidably fitted upward and the discharge valve provided on the top wall. There is known a pump device configured as described above.

However, in this kind of conventional container, the cream-like material is often clogged in the discharge valve, and the trouble that the smooth dispensing of the contents is hindered often occurs, especially when the viscosity of the cream-like material is high. Met.

The present invention provides an excellent dispensing container which solves such conventional disadvantages.

[Means for Solving the Problems] In an outer cylinder 2 having upper and lower ends closed, an inner cylinder 3 having an opening on a lower end surface having an outer peripheral surface located at a predetermined interval from the inner peripheral surface of the outer cylinder 2 is attached upward. The inner cylinder 3
A nozzle 14 erected from the top wall 13 penetrates the outer cylinder top wall 7 so as to protrude vertically, and a movable bottom wall 4 fitted around the inner cylinder 3 at the lower portion so as to be slidable around. A lowering prevention mechanism 20 for preventing the lowering of the bottom wall 4 is fitted, and the inner peripheral surface is slidably contacted with the outer peripheral surface of the inner cylinder 3. A ring-shaped movable wall 5 whose surface is slidably contacted with the surface is mounted, and an uplift prevention mechanism 23 for preventing the movable wall 5 from being lifted is provided.

“Action” The inner cylinder 3 is used by filling it with a creamy substance. In use, when the cylinder 3 is pushed down after the cap 26 and the nozzle cap 25 are removed, the sealed space from the inner cylinder below the movable bottom wall 4 to the gap 18 below the ring-shaped movable wall 5 is compressed. You. At this time, since the ring-shaped movable wall 5 does not rise due to the operation of the rise preventing mechanism 23, the movable bottom wall 4 is pushed upward, and the cream-like material in the inner cylinder is discharged from the nozzle 14 accordingly. On the other hand, when the pressing of the inner cylinder 3 is released, the inner cylinder 3 is raised to the original position by the action of the spring 17. At this time, the space increases in volume, the inside of the space becomes negative pressure, and the movable bottom wall 4 does not descend due to the operation of the descent prevention mechanism 20, so that the ring-shaped movable wall 5 descends due to the external pressure.

"Example" Hereinafter, an example of the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a cream-like material discharging container, and the container 1 includes an outer cylinder 2, an inner cylinder 3, a movable bottom wall 4, and a ring-shaped movable wall 5 as main members.

The outer cylinder 2 has a top wall 7 extending from an upper edge of a cylindrical peripheral wall 6, and a bottom wall 8 is fitted by hermetically closing an opening at a lower end surface. Further, a guide tube 9 having the outer periphery of the lower end of the inner tube 3 fitted vertically movably from the center of the upper surface of the bottom wall 8 is provided upright.
In addition, a communication window 10 that communicates the inside and outside of the guide cylinder 9 is provided. Further, a circular window hole 11 for projecting the upper end of the inner cylinder 3 is formed in the center of the top wall 7.

The inner cylinder 3 has a top wall 13 extending from an upper end edge of a cylindrical peripheral wall 12 having a lower end surface opened, and a cross section inverted L from the center of the top wall 13.
The U-shaped cylindrical nozzle 14 is integrally erected, and the upper end of the peripheral wall 12 is partially reduced in diameter to form a reduced diameter portion 15. The outer periphery of the lower end of the inner cylinder 3 is vertically movably fitted to the upper end of the inner periphery of the guide cylinder 9, and the upper end of the inner cylinder 3 is always engaged with a downward step 16 formed at the lower inner periphery of the peripheral wall 12 by a coil spring 17. It is urged upward, and the reduced diameter portion 15 is fitted to the window hole 11 of the outer cylinder top wall 7 so as to be vertically movable. A gap 8 having a predetermined interval is provided between the outer peripheral surface of the inner cylinder 3 and the inner peripheral surface of the outer cylinder 2.

The movable bottom wall 4 has a cylindrical shape with an opening at the lower end surface, and is formed by providing an elastic sliding portion 19 having a V-shaped cross section that protrudes outward from an outer peripheral lower end of the peripheral wall. The inner cylinder 3 is fitted in a liquid-tight, air-tight and slidable manner at the lower portion of the inner circumference.
The movable bottom wall 4 is provided with a plurality of elastic plates projecting outward from the cylindrical base fitted to the inner peripheral surface of the peripheral wall and having their distal ends in contact with the inner peripheral surface of the inner cylinder. A descent prevention mechanism 20 for preventing the movable bottom wall 4 from being lowered is provided.

The ring-shaped movable wall 5 has elastic sliding portions 21 and 22 whose cross sections are inverted from each other from the inner peripheral edge of the ring-shaped wall plate.
And an inner elastic sliding portion 21 on the outer periphery of the inner cylinder 3 and an outer elastic sliding portion 22 on the inner peripheral surface of the outer cylinder 2 in an airtight and slidable manner. Mated. Also, a plurality of elastic plates are protruded from the ring-shaped movable wall 5 from a ring-shaped base fixed to the upper surface of the wall plate of the ring-shaped movable wall 5, and the ends thereof are brought into contact with the outer periphery of the inner cylinder 3. , A rising prevention mechanism 23 for preventing the ring-shaped movable wall 5 from rising.

In the drawing, reference numeral 24 denotes an intake hole, 25 denotes a nozzle cap, and 26 denotes a cap. Further, it is preferable that all of the above members are formed of synthetic resin.

"Effect of the invention" As described above, the cream-like material dispensing container of the invention is
With the configuration described above, the contents can always be smoothly poured out. Also, the structure is simple and can be easily manufactured.
