Description

Technical Field

[0001] This invention relates to the field of pipette tip assembly technology, specifically a chain-type packaging structure for high-efficiency insert pipette tips. Background Technology

[0002] Pipettes, as laboratory consumables used in conjunction with pipettes or automated equipment, are used to aspirate and deliver highly precise volumes of liquids. Currently, pipette tips are mainly packaged in two ways: boxed and bulk. Boxed pipette tips are sold together with their containers, often used for molecular experiments requiring higher levels of enzyme-free and sterile handling; therefore, the entire package undergoes enzyme-free and sterile processing, resulting in higher costs. Bulk pipette tips, on the other hand, are a more economical packaging method. A larger number of pipette tips are loosely packed into plastic bags. Before use, each tip must be manually inserted into its container and sterilized at high temperature. Bulk pipette tips significantly reduce packaging space and allow for the reuse of the container, making it the mainstream packaging method in laboratories. However, manually inserting bulk pipette tips into their containers is a time-consuming and labor-intensive task. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a chain-type packaging structure for efficient insertion of pipette tips. It innovatively uses an easily detachable chain-type packaging structure to position the pipette tips in a row, effectively improving the insertion efficiency of bulk pipette tips.

[0004] A high-efficiency chain-type packaging structure for insert-type pipette tips, the technical solution of which is as follows: The chain-type packaging structure is provided with chain-type positioning holes that perfectly match the hole position matrix of the target pipette tip box. The number and spacing of the positioning holes in a single row are consistent with the corresponding hole column of the pipette tip box. The pipette tips are precisely constrained to preset spatial coordinates through the positioning holes, and the fixing methods include, but are not limited to: plastic snap-fit ​​structure, elastic thin wire binding, soft film clamping, or peelable adhesive layer. The tail or head extension of the packaging structure is convenient for hand grasping and tearing. During assembly, the operator inserts the entire stack of pipette tips into the pipette tip box, holds the upper end of the pipette tip with one hand, and applies peeling force with the other hand to detach the packaging structure.

[0005] Its further feature is that the chain-type packaging structure can be one of four types of packaging structures: plastic snap-fit ​​structure, elastic thin thread binding, soft film clamping or peelable adhesive layer. The internal structure has a series of positioning holes, the size and arrangement of which are consistent with the corresponding suction head box holes.

[0006] A further feature is that the fixing depth of the elastic plastic snap-fit ​​or elastic thin wire is 1 / 2 to 2 / 3 of the diameter of the suction head neck (the staggered double-layer binding fixation is more conducive to the accurate positioning of the suction head).

[0007] Its further feature is that: the peelable adhesive layer is coated on the plastic strip of the deepened half-hole (2), and the inner diameter of the hole forms a gradient change (wider at the top and narrower at the bottom), which forms a self-centering constraint with the taper of the pipette tip (3).

[0008] Its further features are as follows: the various fixing methods include: the elastic thin wire can be made of TPU material with a diameter of 1mm, cross-shaped binding and double-layer staggered binding for easy positioning; the soft film thickness is 0.1-0.2mm, the opening diameter of the positioning hole is 10%-20% smaller than the neck of the suction head, a narrow edge (5) is left on one side of the positioning hole to facilitate peeling, and a wide edge (6) is left on the other side to prevent the entire film from breaking in the middle during radial tearing and peeling, which would make it impossible to peel off the entire structure.

[0009] The chain-type packaging structure for high-efficiency insert pipette tips described in this invention can significantly improve efficiency, for example, reducing the assembly time of a 96-well pipette tip box from about 120 seconds to less than 20 seconds; and compared with boxed pipette tips, the packaging cost is reduced, and the amount of packaging materials used is greatly reduced.

Detailed Implementation

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0012] Please refer to the following: Figure 1A chain-type packaging structure for high-efficiency insert pipette tips includes elastic plastic clips or elastic thin wires. Suitable pipette tips are inserted into the corresponding holes on the elastic plastic clips or bundled together in a row with elastic thin wires and double-layered for fixation. The entire row of fixed pipette tips can be bagged at will. When using the pipette tips packaged in this structure (3), the user only needs to insert the tips of the entire row of pipette tips into the corresponding holes in the tip box, hold the top of the tip with one hand, and peel off the extended peeling end of the packaging structure with the other hand to remove the packaging positioning material (see...). Figure 2 This completes the insertion of the entire row of pipette tips. Besides single-row packaging, flexible plastic clips or elastic wires can also be used for matrix-style multi-row fixing, using a similar method. Example

[0013] Please refer to the following: Figure 3 A chain-type packaging structure for high-efficiency insert pipette tips includes a specially thickened elastic plastic clip and a peelable adhesive layer. The peelable adhesive layer is coated on the plastic clips of the deepened half-holes (2), and the inner diameter of the holes forms a gradient change that is wider at the top and narrower at the bottom, forming a self-centering constraint with the taper of the pipette tip (3). The selected pipette tip is neatly pressed into the corresponding hole and fixed by the peelable adhesive layer. When using the pipette tips (3) packaged with this structure, the user only needs to insert the tips of the entire row of pipette tips into the corresponding holes of the tip box, hold the upper part of the tip with one hand, and peel off the plastic clips of the peelable adhesive layer with the other hand to complete the insertion of the entire row of tips. Example

[0014] Please refer to the following: Figure 4 A chain-type packaging structure for high-efficiency insert pipette tips includes a soft film clamping and fixing packaging structure. The soft film material has a positioning hole diameter that is 10%-20% smaller than the tip neck. A narrow edge (5) is left on one side of the positioning hole for easy peeling, while a wide edge (6) is left on the other side to prevent the entire structure from breaking off in the middle during tearing. A suitable pipette tip is selected, and the tip is inserted into the corresponding hole. Appropriate pressure is applied to clamp and fix the pipette tip with the soft film material. The entire row of fixed pipette tips can be bagged at will. When using the pipette tips (3) packaged in this structure, the user only needs to insert the tips of the entire row of pipette tips into the corresponding holes in the tip box, hold the upper end of the tip with one hand, and pull the extended end of the packaging towards the wide side with the other hand to apply radial force for tearing. This will break the narrow side, separating the soft film material from the tip, thus completing the insertion of the entire row of pipette tips.
