Description

Technical Field

[0001] This utility model provides a sealed test tube, which relates to the field of biological experimental equipment technology. Background Technology

[0002] Ready-to-use test tubes for culture medium are products where liquid culture medium is aseptically filled into disposable plastic test tubes for direct use by laboratory personnel. These products are convenient to use, significantly saving preparation time, manpower, and resources. However, leakage frequently occurs during transportation after opening the tubes. Various improvements, such as locking mechanisms, have been implemented to prevent leakage, completely resolving the problem. However, these locking mechanisms result in test tube heads that are too large, causing overcrowding when placed in a standard test tube rack, hindering neat arrangement and sample addition. Furthermore, the locking mechanism design is too sophisticated, leading to high costs and relatively cumbersome usage. Utility Model Content

[0003] This utility model provides a sealed test tube, which solves the technical problem in the prior art that the sealed test tubes have a large head due to the locking design, and cannot be neatly arranged after being put into a conventional test tube rack.

The upper end of the test tube body is provided with an open end, and the bottom end of the test tube body is a closed end.

[0005] The cap is fitted with a rubber stopper that fits the opening. The rubber stopper extends vertically downwards and then extends obliquely towards the axis of the rubber stopper to form a lower edge. The lower edge fits the opening. When the cap is fastened to the test tube body, the oblique lower edge falls into the range of the test tube body. The inner wall of the cap is provided with a buckle protrusion extending horizontally towards the axis of the cap. The upper part of the tube body is provided with a first ring and a second ring. The first ring is lower than the opening and is located above the second ring. The diameter of the first ring is smaller than the diameter of the second ring. The first ring fits the inner diameter of the cap.

[0006] As a further preferred embodiment, the top inner surface of the cover is provided with a post, and the upper center of the rubber plug is provided with a connection hole adapted to the post.

[0007] As a further preferred embodiment, a first sealing ring is provided above the lower edge, the diameter of the first sealing ring being adapted to the outer diameter of the opening end.

[0008] As a further preferred embodiment, the lower end of the cover extends horizontally outward to form a first platform, the second ring extends horizontally outward to form a second platform, and the first platform is adapted to the first platform.

[0009] As a further preferred embodiment, the outer edge of the first platform is a rounded edge, and the outer edge of the second platform is a rounded edge.

[0010] As a further preferred embodiment, the outer side of the cover is provided with a manual control area, which includes a first manual control area and a second manual control area. The first manual control area and the second manual control area are symmetrically arranged, and the upper part of the first manual control area overlaps with the upper part of the second manual control area.

[0011] As a further preferred embodiment, the first dial area extends obliquely to the upper right, and the second dial area extends obliquely to the upper left.

[0012] As a further preferred embodiment, the bottom of the test tube body is provided with a non-slip bottom surface.

[0013] As a further preferred embodiment, the sealed test tube includes an outer packaging, which is a heat-shrink film.
