BIOLOGICAL SAMPLE PRESERVATION TUBE WITH IDENTIFICATION CODE AND METHOD FOR MANUFACTURING THE SAME
First Claim
1. A biological sample preservation tube with an identification code, comprising:
- an information element including a core layer and a heat sealing layer, the core layer containing the identification code and the heat sealing layer being transparent and overlaid on the identification code; and
a tube body having an integrally injection molded bottom wall and side wall, at least one of the bottom wall and the side wall is integrally fused with the information element in an injection molding process.

Abstract
The present invention relates to a biological sample preservation tube with an identification code, wherein an information element which records the sample information is fused integrally with the bottom wall and/or side walls during molding the preservation tube, the preservation tube is suitable for the preservation of a biological sample at low temperature and can ensure the effectiveness and stability at low temperature; and at the same time also relates to a method for manufacturing the biological sample preservation tube, wherein the preservation tube is molded by a one-step process, without an additional secondary processes for manufacturing the identification code, the method improves the production efficiency, reduces the production cost, employs multi-point symmetrical feeding, and has good quality and stability of the product, so that the method is of great significance as it opens up a new idea for developing and producing the similar product in the industry, especially the small-sized preservation tube with an identification code.

8. A method for making biological sample preservation tube with an identification code, comprising:
-
manufacturing an information element, including;
printing the identification code on a core layer;
overlaying an inner surface of a heating sealing layer on the identification code of the core layer; and
forming the information element by integrating the core layer and the heat sealing layer;cutting the information element, including;
cutting the information element into a size not exceeding that of a position to be fused, and each cut information element is removed off static electricity to avoid attaching to each other; and
placing the cut information element on a same support frame as a mould, for being taken by a robotic hand;picking and placing the information element, including;
placing the cut information element on a predetermined position in the mould by the robotic hand, with a side of the cut information element having the identification code facing away from an inner core attached to an outer wall of a mould cavity;
applying static electricity on the cut information element such that the cut information element is attached onto the mould under the effect of the electrostatic field for temporary fixation; andperforming mould closing and injection molding to form the biological sample preservation tube, including;
injecting molten plastic feedstock into the mould via at least two symmetric feed channels from both sides of the mould, each feed channel being reflexed at a point close to a feed inlet pointing to a center position of a bottom side of the mould. - View Dependent Claims (9, 10)
