The axial cross section of the cylinder body 10 is illustrated in a circular shape, but the present invention is not limited thereto, and may have a polygonal shape such as a triangle or a square as well as an oval.

The cylinder body 10 may be formed of metal, carbon fiber, synthetic resin, or a combination thereof, and has mechanical or chemical resistance to the moisture, temperature or atmosphere of the external environment in which the small container 100A is used or stored. It can be formed of a material of Preferably, the cylinder body 10 forms a strong barrier against moisture and air, and is a metal with high strength, and may be, for example, aluminum, tungsten, stainless steel or any alloy. If desired, the outer surface 10OS or the inner surface 10IS of the cylinder body 10 may be coated or have a surface treatment layer such as anodizing to provide a surface with enhanced corrosion resistance or improved mechanical strength.

The first end 10E1 and the second end 10E2 of the cylinder body 10 have an opening through which the substance LC can be injected or discharged. When the material (LC) is accommodated in the small container (100A), in order to prevent its leakage, the opened first end (10E1) and the second end (10E2) are at least partially inserted into the cylinder body (10). Each is sealed by the first stopper 20A1 and the second stopper 20A2. In the embodiment shown in FIG. 1A , the first stopper 20A1 and the second stopper 20A2 are shown fully inserted inside the cylinder body 10 . In another embodiment, the first stopper 20A1 and the second stopper 20A2 are fully inserted into only one of the first end 10E1 and the second end 10E2, respectively, and the other is only partially inserted therein. it might be In this case, the portion exposed to the outside of the partially inserted stopper may have a shape surrounding the corresponding end of the cylinder body 10 .

The first bung 20A and the second bung 20B are not coupled to the cylinder body 10 in the same way as a threaded coupling, but to the inner surface 10IS of the cylinder body 10 along a line DL. It is inserted in a sliding manner, and the side surfaces of the first stopper 20A and the second stopper 20B are sealed in such a way that the inner surface 10IS of the cylinder body 10 is pressed.

수지로 형성될 수 있다. 일 실시예에서, 제 1 마개(20A1)와 제 2 마개(20A2)는 측면에는 링형 실링 부재(20R)가 더 제공될 수 있다. 링형 실링 부재(20R)는 통상의 오링이나 금속링일 수 있으며, 본 발명이 이에 한정되는 것은 아니다.The first stopper 20A1 and the second stopper 20A2 may include synthetic resin, synthetic rubber, natural rubber, metal, or a combination thereof, and the present invention is not limited thereto, and the material LC inside is invaded. Alternatively, it may have any material that is not eroded to prevent leakage. Preferably, the first stopper 20A1 and the second stopper 20A2 are made of silicone rubber or Teflon.

Each end of the flexible linker 30 may be coupled to the opposite surfaces 20IS1 and 20IS2 (hereinafter referred to as the inner surface of the stopper) of the first stopper 20A1 and the second stopper 20A2. In Figures 1a and 1b, each end of the flexible linker 30 is illustrated coupled to the central portion of the inner surfaces 20IS1 and 20IS2 of the first stopper 20A and the second stopper 20A2, but the present invention relates to this It is not limited. The flexible linker 30 allows the first stopper 20A1 and the second stopper 20A2 to hang from each other, so that when injecting the substance LC into the cylinder body 10 or from the cylinder body 10, the first stopper ( 20A1) and the second stopper 20A2 is separated to maintain the connection between the first stopper 20A1 and the second stopper 20A2 in the process of discharging the liquid aqueous solution LC from the cylinder body 10. Accordingly, if any one of the stoppers 20A1 and 20A2 is coupled to the body to the cylinder body 10, since the disconnected other stopper also remains connected, the stoppers ( It facilitates the recovery of 20A1, 20A2). This will be described later with reference to FIGS. 2C and 5C.

The flexible linker 30 is formed of a freely bendable material. In addition, since it is immersed in the material LC in the cylinder body 10 , it must be formed of a stable material that does not contaminate or change the material LC. The material of the flexible linker 30 may be the same as that of the first stopper 20A and the second stopper 20A2. In one embodiment, when the first stopper 20A1 and the second stopper 20A2 are made of synthetic resin or synthetic rubber, the flexible linker 30 is made of the same material as the first stopper 20A1 and the second stopper 20A2. As, by injection with them, the first stopper (20A1), the second stopper (20A2) and the flexible linker 30 may be integrally molded.

2A to 2C illustrate a method of delivering a substance using a small container according to an embodiment of the present invention.

Referring to FIG. 2A , the first stopper 20A1 and the second stopper 20A2 are completely inserted into the end of the cylinder body 10 and are recessed in the cylinder body 10, the first stopper 20A1 and the second stopper When the stopper 20A2 strongly presses the inner surface 10IS of the cylinder body 10, the first stopper 20A1 and the second stopper 20A2 are pulled outwardly from the cylinder body 10 in a manner difficult to separate In particular, in the case of the small container 100A according to the embodiment of the present invention, since the user cannot separate the first stopper 20A1 and the second stopper 20A2 from the cylinder body 10 without a special tool, for example, For example, since it is difficult for children or unskilled users to separate the caps 20A1 and 20A2 , there is an advantage in that a safety accident exposed to the material LC can be prevented.

In one embodiment, a rod 40 is provided to open either the first bung 20A1 or the second bung 20A2 for use of the material 10 contained within the cylinder body 10 . The rod 40 has an outer diameter smaller than the inner diameter of the cylinder body 10 , so that it can slide in the cylinder body 10 .

Referring to FIG. 2B , when a user contacts the end 40E of the rod 40 from the outside to the outer surface of the first stopper 20A1 and applies a strong pressure as indicated by an arrow P, the first stopper 20A1 ) is displaced toward the second stopper 20A2 along the central axis (see 10C in FIG. 1B ). At this time, while pressure is also applied to the material LC, the pressure is transmitted to the second stopper 20A2 through the material LC, and the second stopper 20A2 is displaced within the cylinder body 10, so that the second stopper 20A2 is displaced. The bung 20A2 is separated from the second end 110E2. As a result, the substance LC accommodated in the cylinder body 10 is discharged out of the cylinder body 10 as indicated by the arrow K. The second stopper 20A2 separated from the cylinder body 10 is not separated by the first stopper 20A1 supported by the cylinder body 10 and the flexible linker 30 connected thereto. Since the pressure applied to the first stopper 20A1 is transmitted to the second stopper 20A2 through the material LC, when the material LC is a gaseous phase, it may be a compressed gas, and the material LC may be a liquid or In the case of the solid phase, the pressure can be easily transferred without changing the volume of the material LC.

Referring to FIG. 2C , the material LC contained in the small container 100A may be transferred to another outer container OB for use. The outer container OB may contain a solvent or substance LC for dilution and other substances (hereinafter referred to as external substances) for pharmaceutical, medical, cosmetic, food or taste to be mixed. Inserting the second end 10E2 of the cylinder body 10 sealed by the second stopper 20A2 through the opening of the outer container OB into the outer container OB, as described with reference to FIG. 2B , After the user contacts the end 40E of the rod 40 with the outer surface of the first stopper 20A1 from the outside, and applies a strong pressure as indicated by the arrow P, the central axis 10C of the cylinder body 10 The material LC pushes the second stopper 20A2 out of the cylinder body 10 by the first stopper 20A1 displaced along the As the second stopper 20A2 is separated from the cylinder body 10 in the outer container OB, the cylinder body 10 is fully opened. As a result, the inner material LC is discharged to the outside of the cylinder body 10 and transferred to the outer container OB.

By the flexible linker 30, the second stopper 20A2 is maintained in a bonding state with the small container 100A, and when the small container 100A is recovered after the delivery of the substance LC is completed, the cylinder body 10 is The second stopper 20A2 is simultaneously withdrawn by the first stopper 20A1 supported by the .

The length of the rod 40 may be determined so that the material LC can be delivered by a predetermined amount. In one embodiment, the length of the rod 40 may be greater than or equal to the length of the cylinder body 10 . In another embodiment, the length of the rod 40 may have a size obtained by subtracting the thickness of the first stopper 20A1 from the length of the cylinder body 10 . In this case, when the rod 40 is completely inserted into the cylinder body 10, the inner surface 20IS1 of the first stopper 20A1 is completely out of the cylinder body 10, as shown in Fig. 2C. The remaining amount of the material LC exposed on the inner surface 20IS1 of the first stopper 20A1 is completely exposed to the foreign material in the outer container OB, thereby shaking or stirring the outer container OB. In this way, the remaining amount of the substance LC may be washed with an external material accommodated in the external container OB, for example, a liquid solvent, and then substantially completely transferred to the external container OB.

In one embodiment, a jig GT for holding the cylinder body 10 while applying the pressure P to the rod 40 may be used. The first stopper 20A1 can be displaced by fixing the cylinder body 10 with a jig GT and pressing the rod 40 . In one embodiment, the rod 40 may be provided with an expanded surface 40S to expand the area to which the pressure P is applied.

The elastic metal body, which is compression-deformed, has a flexible linker 35 between the inner wall of the first stopper 20C1 and the cylinder body 10 by bending while the first stopper 20C1 moves toward the second stopper 20C2. It is pinched to prevent the advancement of the first stopper 20C1 from being obstructed. Specifically, while the first stopper 20C1 moves toward the second stopper 20C2, the flexible linker 35, which is a compressively deformable metal elastomer, is directed toward the second stopper 20C2 to relieve the compressive stress. As it is bent by tensile strain, the bent region of the flexible linker 35 moves away from the first stopper 20C1. Accordingly, according to the embodiment of the present invention, the bent region of the flexible linker 35 between the first stopper 20C1 and the inner wall of the cylinder body 10 is the second stopper with the displacement of the first stopper 20C1. While moving toward 20C2, smooth displacement of the first stopper 20C1 is possible while the first stopper 20C1 moves toward the second stopper 20C2.

For bonding between both ends of the flexible linker 35 and the respective inner surfaces 20IS1 and 20IS2 of the first stopper 20C1 and the second stopper 20C2, the first stopper 20C1 and the second stopper 20C2 A fixing portion 25 may be provided at the center of the inner surfaces 20IS1 , 20IS2 . The end of the flexible linker 35 may be coupled in a manner that surrounds the fixing portion 25 or the end of the flexible linker 35 is inserted into the fixing portion 25 and coupled in a manner. In Figure 3b, it is illustrated that the end of the flexible linker 35 is coupled in a manner surrounding the fixing portion (25). In this case, a rubber ring 25R may be provided on the sidewall of the fixing part 25 in order to increase the bonding force due to friction between the fixing part 25 and the flexible linker 35 .
