Description

Technical Field

[0001] This utility model belongs to the field of storage containers, specifically relating to a storage kit for powders and liquids. Background Technology

[0002] Freeze-dried powder is a modern biotechnology product prepared by freeze-drying live cells and tissues into a powder form using biotechnology methods. Freeze-dried powder typically consists of two parts: a powder and a liquid. When using freeze-dried powder, the powder and liquid need to be mixed to form the desired liquid. It can be used in cell culture, virus research, and the preparation of biopharmaceuticals.

[0003] Since the powder and liquid of this product need to be stored separately during the sales stage or before use, prior to this invention, the powder and liquid of freeze-dried powder were usually simply stored separately in two containers, and the user would then pour and mix them when using them. This mixing method was inconvenient, and the powder or liquid was prone to spillage during mixing. Utility Model Content

[0004] In order to address the problems in the background art, and to enable the powder and liquid of freeze-dried powder to be stored separately during the sales stage, and to facilitate mixing and prevent spillage during use, this utility model provides a powder and liquid storage kit, which includes a tube, a stopper, a rubber nozzle, a dropper cap, a bottle body, and a bottle cap.

[0005] The tube contains powder, and the lower opening of the tube is sealed with a plug to prevent the powder from leaking out. The upper end of the tube and the lower opening of the nozzle are connected by a dropper cap. Of course, the tube and the nozzle are internally connected.

[0006] The bottle contains liquid, and the side of the bottle opening has external threads, while the inner side of the bottle cap has internal threads. The bottle cap can be screwed onto the bottle opening through the threads.

[0007] The inner side of the dropper cap has an internal thread. After unscrewing the cap on the bottle body, removing the stopper from the tube body, and inserting the tube body into the bottle body, the dropper cap can also be screwed onto the opening of the bottle body through the thread. After this assembly is completed, pressing the rubber head a few times will cause the powder in the tube body to spray out and dissolve and mix with the liquid in the bottle body, making the mixing operation convenient and preventing the powder and liquid from spilling.

[0008] Preferably, the dropper cap has a split structure, comprising an upper cap and a threaded cap, which can be assembled and connected; the lower opening edge of the rubber head is bent outward to form a pressure ring, and a first annular mounting groove is provided on the side of the rubber head above the pressure ring;

[0009] The top surface of the upper cover is provided with a through hole. The edge of the through hole of the upper cover is fitted into the first annular mounting groove of the rubber head to realize the assembly connection between the upper cover and the rubber head, and at the same time, the pressure ring of the rubber head is located in the upper cover. The lower end opening edge of the upper cover protrudes inward to form a buckle. The upper cover is an elastic cover that can undergo a certain elastic deformation.

[0010] The inner side of the threaded cap is provided with an internal thread, which can cooperate with the external thread of the bottle to realize the assembly of the threaded cap and the bottle. The top surface of the threaded cap also has a through hole, and a convex ring is integrally connected above the through hole of the threaded cap. The upper edge of the convex ring protrudes outward and forms a groove with the top surface of the threaded cap.

[0011] A sealing ring is fixedly connected to the upper opening of the tube body. The seat of the sealing ring can be placed inside the convex ring of the threaded cap, and the ring of the sealing ring can be placed on the top surface of the convex ring. Before the rubber head and the tube body are assembled and connected, it is convenient to inject powder into the tube body from the upper opening. When the rubber head and the tube body are assembled and connected through the dropper cap, that is, when the upper cap is pressed down so that its snap is placed in the slot of the threaded cap, the pressure ring of the rubber head can be squeezed against the ring of the sealing ring to form a seal. This facilitates the assembly and connection, and can form a good seal at this point, effectively preventing moisture in the air from entering the tube body from here.

[0012] The assembly connection between the upper cover and the threaded cover using snap fasteners can also be replaced with the following form: the inner side of the upper cover has an internal thread, and the outer side of the convex ring has a corresponding external thread, so that the upper cover can be tightened onto the convex ring of the threaded cover by the thread; this makes it easier to assemble and disassemble the upper cover and the threaded cover.

[0013] Preferably, a second annular mounting groove is provided on the inner side of the sealing ring, and a retaining ring is integrally connected to the upper end side of the tube. Because the sealing ring is made of rubber and has elasticity, the retaining ring of the tube can be fitted into the second annular mounting groove of the sealing ring to achieve a limiting and fixed connection between the tube and the sealing ring. A retaining ring is also integrally connected to the inner side of the convex ring. After assembly, the sealing ring is located above the retaining ring. This limiting setting of the retaining ring can prevent consumers from accidentally pulling the tube out of the sealing ring. At the same time, the retaining ring can also increase the sealing effect.

[0014] Preferably, a plug strip is integrally connected to the inner bottom surface of the plug. The plug strip can be placed inside the tube. The plug strip facilitates the insertion of the plug and also ensures the sealing of the lower end of the tube.

[0015] Preferably, both the internal and external threads are three-start threads. Three-start threads have strong sealing performance and are also easier to assemble or disassemble from the bottle cap and dropper cap to the bottle body.

[0016] Through the above technical solutions, this utility model has at least the following beneficial effects:

[0017] The powder and liquid storage kit described in this application, through the coordinated design of structural components such as the tube, stopper, rubber nozzle, dropper cap, bottle body, and bottle cap, allows the freeze-dried powder and liquid to be stored separately in the tube and bottle during the sales stage. When using it, the user only needs to unscrew the bottle cap, remove the stopper from the tube, insert the tube into the bottle, and finally screw the dropper cap onto the bottle body. After assembly, simply press the rubber nozzle a few times to spray out the powder in the tube and dissolve and mix it with the liquid in the bottle, making the mixing operation convenient and preventing spillage of powder and liquid.

[0018] In the preferred embodiment, the split-type dropper cap design facilitates the assembly and connection of the nozzle and the tube body during production. Before assembly, the powder can be easily injected into the tube body from the opening at the top. After the nozzle and the tube body are assembled using the split-type dropper cap, a good seal can be formed at the connection point, effectively preventing moisture in the air from entering the tube body from here.
