Description

Solid-liquid separation type freeze-dried sample mixing bottle

Technical Field

The utility model belongs to biological medicine container field, concretely relates to freeze-drying sample mixing bottle of solid-liquid separation formula.

Background

In the field of biopharmaceuticals, lyophilized samples are shipped in containers that are proprietary to the particles, powders, liquids. Among them, penicillin bottles are widely used as liquid containers, and penicillin bottles are small bottles sealed by rubber plugs, so penicillin bottles are named because penicillin bottles are used for containing penicillin in early stages. The bottle lid of depositing on the existing market is mostly traditional plug, and can only adorn the object-solid or the liquid of a form in same bottle, therefore freeze-dried sample and desolventizer need two containers to be preserved. When in use, the sample needs to be firstly centrifuged at high speed, and then the re-dissolution is carried out by using the re-solvent, so that the process is troublesome. Meanwhile, in the process of opening the cap of some samples, the samples can be stuck to the outer edge of the bottle stopper or the bottle opening, so that the sample loss and the redissolution concentration are easily caused. Accordingly, there is a need in the art for a new freeze-dried sample storage bottle with solid-liquid separation to solve the above problems.

Disclosure of Invention

In order to solve the above problems in the prior art, i.e. to solve the problem that the existing container can not contain two different forms of solid and liquid simultaneously and avoid sample loss, the present invention provides a solid-liquid separation type freeze-dried sample mixing bottle, which comprises a bottle body and a bottle cap, wherein the bottle body is used for storing freeze-dried samples and has a bottle mouth, the bottle cap is used for sealing the bottle mouth, the bottle cap comprises a liquid cavity, a screw cap with a needle and a container cap, the container cap is connected with the bottle mouth, a containing cavity for containing liquid is arranged above the container cap, the screw cap with the needle is arranged between the liquid cavity and the container cap and is connected with the needle, and the outside of the needle is wrapped by a rubber core, when the screw cap with the needle is screwed, the needle can pierce the rubber core, and the liquid can automatically flow into the bottle body through air pressure difference due to the vacuum environment in the bottle body, mixing with the solid.

In the technical scheme of the utility model, the container lid with the bottleneck is through sealed joint of spiral cooperation mode.

The technical scheme of the utility model in, the band needle nut need be twisted at least and twisted two weeks and just enable the syringe needle and pierce the rubber core for when not needing to mix prevent the syringe needle mistake pierces the rubber core.

The utility model discloses a mixing bottle includes liquid chamber, band needle nut and container lid, before the use, the accessible revolves soon the band needle nut, makes the syringe needle pierce through the rubber core to make the liquid of liquid intracavity mix with the solid of putting into the bottle in advance. The utility model discloses can make solid and liquid in the single container, do not influence each other in transportation and storage process to facilitate the use and guarantee that the sample does not have the loss.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings and the detailed description, the examples being provided for the purpose of illustration only and not for the purpose of limiting the scope of the invention.

It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1, the freeze-dried sample mixing bottle for solid-liquid separation comprises a bottle body 3 and a bottle cap, wherein the bottle cap comprises a liquid cavity 1, a screw cap 7 with a needle and a container cap 2, a re-solvent is stored in the liquid cavity 1, a freeze-dried sample 4 is contained in the bottle body 3, the liquid cavity 1 and the container cap 2 are connected through the screw cap 7 with the needle, and the bottle body 3 and the container cap 2 are connected in a sealing manner through threads. The needle head 6 below the center of the needle-contained screw cap 7 is communicated with the liquid cavity 1, and the periphery is wrapped by the rubber core 5. When the bottle is not opened, the re-solvent above the bottle cap is not in contact with the freeze-dried sample 4 in the bottle body 3, and the bottle body 3 is in a vacuum state.

As shown in fig. 2, solid-liquid separation's freeze-dried sample mixing bottle is when using, clockwise rotation takes needle nut 7 two weeks, make syringe needle 6 pierce through rubber core 5, intercommunication liquid chamber 1 and body 3, because be vacuum state in the body 3, the desolvation in the liquid chamber 1 can receive the automatic flow of atmospheric pressure influence to mix with freeze-dried sample 4 in the body 3, thereby realize the redissolution of freeze-dried sample under the prerequisite of not uncapping, the process that the re-dissolving heavy suspension was needed to the freeze-dried sample earlier high-speed centrifugation, the waste of the freeze-dried powder of this in-process different degree has been avoided simultaneously.

It will be understood by those skilled in the art that the container cover 2 and the bottle body 3 may be engaged by other means, such as a snap-fit type, instead of a screw-type engagement, but not limited to a single engagement.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
