Description

Technical Field

[0001] The present invention relates to the technical field of containers, in particular to a container for transferring and storing liquids. Background Art

[0002] In the prior art, when liquid needs to be transferred into a container, in order to facilitate the transfer of the liquid, the container for carrying the transferred liquid is usually configured to have a certain vacuum inside, so as to facilitate the attraction of the liquid at the moment of establishing the transfer connection. At the same time, since the internal space of the container is vacuum, the filling of the liquid will not cause the discharge of other additional substances, thereby avoiding the exchange of substances inside and outside the container and realizing the sealed transfer of the liquid.

[0003] During the stages of production and storage before use, the above-mentioned containers usually face defects such as leakage and loss of negative pressure to varying degrees as time and external factors change. The containers in the prior art usually cannot accurately reflect the degree of change in their internal vacuum before use, resulting in the container not being aware of the loss of normal transfer function before use, affecting its use. Moreover, each time it is used, it cannot be operated in a standardized manner due to the change in negative pressure. Once the vacuum inside the container has a small loss, it is difficult to adjust and remedy it and the container can only be discarded, resulting in the defects of cumbersome operation, high cost and great waste.

[0017] Instructions for use: container 1 is used to transfer liquids. Container 1 can be made of various materials, such as PET, polypropylene PP, polyethylene PE, polystyrene PS, high-density polyethylene PE-HD, acrylonitrile, butadiene styrene ABS or the like or a combination thereof; the closure cap 2 is made of plastic materials of various colors, so that it can be better distinguished and operated during use, and the outer layer of the closure cap 2 is provided with vertical lines for user convenience; the sealing body 5 is made of a material with high elasticity and can be pierced by a catheter for introducing or leading out fluids.

The specific material can be a thermoplastic elastic plastic, such as tributyl rubber.

[0018] During observation, since the sealing sleeve 324 is in active contact with the inner side of the container 1 to form a pressure chamber having a pressure different from that of the outside, the pressure inside the pressure chamber drives the sealing sleeve 324 to generate a pulling force in the direction of the container 1 opposite to the pressure balance structure 33; since the container 1 has a transparent part, the different pressure differences between the inside and outside of the container 1 can generate different traction forces on the sealing sleeve 324, and under the reaction force of the pressure balance structure 33, the sealing sleeve 324 can eventually show different position changes on the container 1. According to the changes of the sealing ring 324 between the scale bars 6, the operator can make a quick, intuitive and accurate judgment on the sealing pressure inside the container before use, so as to avoid unnecessary influence on the liquid transfer operation caused by the container 1 that has completely or partially lost its vacuum.

[0019] When adjusting the internal pressure, according to the different standards or needs of the internal pressure of the container 1 in actual situations, in order to be able to continue to use the container 1 that has lost the vacuum degree for liquid transfer, when the vacuum degree inside the container 1 is insufficient, rotate the adjusting knob 722, and the adjusting knob 722 drives the lead screw 721 to rotate and produce displacement, thereby driving the support plate 723 to push the deformed bottom 71 to reduce the internal space of the container 1 and increase its internal pressure, or correspondingly reduce the internal pressure of the container 1 to facilitate the transfer of the liquid, and adjust the pressure inside the container according to the needs of solution input or output.

[0020] The beneficial effects of the present invention are summarized as follows: first, the sealing sleeve is driven to move by the internal pressure, and the different position changes of the sealing sleeve on the container reflect the degree of internal vacuum changes, which is more convenient for observation and use; second, the deformation of the deformable bottom is driven by the movement of the telescopic structure to adjust the internal pressure of the container, which is simple to operate, has little waste, and reduces costs.
