Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a small container for pouring a fluid such as a liquid or a cream.

"Prior art" A main cylinder member erecting a small-diameter cylindrical portion from the upper end of a body portion of a lower end surface opening, and erecting a fitting cylindrical portion closed at the upper end surface from the upper end of the small-diameter cylindrical portion via a break line. A cap-shaped tubular portion which is fitted upright by tightly fitting the lower tubular portion to the outer surface of the tubular portion, and which is sandwiched by the inner surface of the small-diameter tubular portion, rises from the inside of the barrel, and has an upper end inserted into the fitting tubular portion. A fitting tube portion and a cap-shaped tube portion which are composed of a liquid suction core and a bottom plate member for sealing the lower end surface of the body portion, store the application liquid in the body portion, and are integrally connected by cutting along a break line; To allow application at the upper end of the suction core, and after the cutting, the cap-shaped member with the fitting cylindrical portion is inverted with respect to the main cylinder, and the opening side of the upper end of the cap-shaped member is set in the main cylinder. 2. Description of the Related Art There is known a small-sized application container which is detachably fitted to a small-diameter cylindrical portion.

[Problem to be Solved by the Invention] The present invention proposes a small container for storing a fluid, which is convenient for storing mainly a single-use volume such as a liquid medicine and cosmetics. It is easy to get out.

[Means for Solving the Problems] An excision tube portion 4 having a smaller outer diameter than the body portion is erected from the upper end of the cylindrical body portion 2 having an opening at the lower end surface via a break line 3, and the upper end surface of the resection tube portion is The main cylinder member 1 which hangs the plug 6 from the center of the lower surface of the top wall 5 to be closed, and the short cylindrical piston 11 which is fitted to the inner surface of the upper end of the body in a watertight manner, is loosely inserted into the cutting cylinder 4. Then, the nozzle 12 is erected, and the injection port at the upper end of the nozzle is sealed by the stopper 6 and the upper surface of the central portion of the bottom plate 16 fixed to the lower inner surface of the body 2 in a watertight manner. Inner member 15 that is inserted into the lower part of the nozzle to raise guide rod 17
The outer diameter of the guide rod 17 is made smaller than the inner diameter of the nozzle 12 so that the discharge cylinder member 10 can be pushed down with respect to the inner member 15, and a fluid is provided between the inner surface of the nozzle and the outer surface of the guide rod. An outflow gap was provided.

[Operation] After holding the body 2 with one hand and breaking off the resection cylinder 4 with the other hand from the state shown in the figure, if the nozzle 12 is pressed down against the body, the guide rod 17 Rises,
The fluid between the bottom plate 16 and the short cylindrical piston 11 is a guide rod 17
Is discharged from the spout through the space between the nozzle and the inner surface of the nozzle 12.

"Example" 1 is a main cylinder member, and a cutting cylinder part 4 having a smaller outer diameter than the trunk part 2 is erected from the inner peripheral edge of an upper end of a cylindrical trunk part 2 having an opening at a lower end face through a breaking line 3. The upper end surface of the resection tube is closed by a top wall 5, and a plug 6 hangs down from the center of the top wall.

The pouring cylinder member 10 is fitted into the upper part of the main cylinder member. The member is loosely inserted into the cutting cylinder 4 from the inner periphery of the short cylindrical piston 11 fitted to the inner surface of the upper end of the body to erect the nozzle 12, and the spout at the upper end of the nozzle is The stopper 6 is tightly fitted. The short cylindrical piston 11 is provided with an inward flange-like wall at an intermediate portion of the cylindrical portion 11a as shown in the figure, and the upper and lower portions of the cylindrical portion are expanded upward and downward. Is preferably formed to be elastically deformable.

Reference numeral 15 denotes an inner member having a bottom plate 16 fixed to the lower portion of the body portion 2 in a watertight manner, and inserted into the lower portion of the nozzle 12 from the upper surface of the center of the bottom plate to raise the guide rod 17. The guide rod 17 is provided so as to fit into the nozzle 12 by pushing down the ejection cylinder member 10, and its length may be substantially the same as that of the nozzle.
Bottom plate 16 and short cylindrical piston 11
The storage fluid between the two is provided so as to flow out from the spout through the space between the guide rod 17 and the inner surface of the nozzle. Torso 2
In order to prevent sliding of the bottom plate 16 with respect to the bottom plate, it is desirable to provide a groove for fitting the outer peripheral surface of the bottom plate around the inner surface of the body. In order to increase the watertightness of the outer periphery of the bottom plate with respect to the inner surface of the body, the bottom plate 16 may be provided with a seal tube portion 16a vertically extending from the outer periphery.

[Effects of the Invention] The present invention has the above-described configuration, and a fluid such as a liquid or a cream-like substance is applied to a portion in a container between the bottom plate 16 of the inner member and the short cylindrical piston 11 of the pouring cylinder member 10. When the nozzle 12 is pushed down with respect to the body portion 2 by removing the resection cylinder portion 4 and then, the fluid is poured out from the spout, so that the pouring operation is easy, and Since the guide rod 17 is inserted, the upper end of the nozzle does not grind when pressed down, and the fluid to be discharged is discharged through the gap between the guide rod 17 and the inner surface of the nozzle. Therefore, it is easy to pour a small amount of the liquid.
