Description

576786 V. Description of the Invention (1) [Technical Field] The present invention relates to a method for manufacturing a container lid, in particular to a container lid structure containing a wood part, and a method for manufacturing a container lid having the structure. [Background of the Invention] Food stuffing in densely air-tight containers can easily accelerate spoilage. However, most of the currently used containers for food or fresh food are paper, plastic or polystyrene. Although the paper container originally had some air permeability, in order to waterproof and increase the strength, it is usually coated with a layer of plastic PE film or chemical wax on the surface of the paper, causing the original breathability to be completely lost. Fresh meat on shelves in supermarkets, or take-out lunch boxes provided by self-help restaurants (bu f i e t), also use Polyurethane or plastic as containers, and sometimes a transparent film is added on top. Food or dishes are stuffed in a Polytron container or plastic container without any chance to breathe, and they will smell even if they are not stuffy. Oriental students have the same problems with plastic or metal lunch boxes used for daily meals. For example, during meals, they often smell miscellaneous flavors of lunch box dishes or some unpleasant quirks. It is also used as a lunch box, but this problem rarely occurs for old-style thin wood chip lunch boxes. According to some scientific literature, this is because the wood chip lunch box has good ventilation properties, and the fenthosin in the wood can inhibit bacteria. . The so-called Fenton IDE (PHYTONC IDE)

Page 4 576786 V. Description of the invention (2) The meaning of PHYON for sterilization (C IDE) was named by Professor Tekin of Leningrad University. Fendoline has the functions of neutralizing and eliminating odors, eliminating odors, and emitting a fresh and refreshing fragrance. The smell is natural and non-irritating, and it is suitable for everyone. / In addition, the natural wood has a porous structure, which contains a series of pores, pores, cell cavities, and capillaries on the cell wall throughout the wood. The cell wall has multiple layers of extremely fine fibers. They are hollow capillaries and pores. Each cell cavity communicates with the adjacent cell cavity through the wall holes in the cell wall; therefore, wood is inherently good in air permeability and water retention, making it an ideal raw food container material. Although thin wood chips have the above-mentioned bacteriostatic, breathable and water-repellent properties, there are always high technical obstacles in processing and forming into containers. The first thing to be urgently overcome is that the transverse strength between the thin wood fiber is very fragile, so it is easy to crack along the fiber direction during processing. As shown in the first figure, Taiwan Patent Bulletin No. 6 3, 3 5 6 "Structure Improvement of Thin Wood Chip Meal Box", it applies sewing stitches 1 to a crease 1 2 of a thin wood chip meal box 10 The purpose of reinforcement is to prevent cracking defects that may occur at any time during mass production of the lunch box. To process thin wood material into Rongyi ’, there are currently great restrictions on three-dimensional modeling. On the other hand, most fresh containers used in supermarkets are mostly made of plastic or Polyurethane injection molding. Its shape can be freely designed and can be varied. Although the natural veneer material contains very good and fresh
