Title: Antibacterial shrinkable film
Inventor: MIZUNO AKIHIKO
IPC: B32B7/02
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To widen the application range for an antibacterial shrinkable film by forming a transparent ink layer containing an antibacterial agent on the shrinkable film. SOLUTION: This antibacterial shrinkable film 5 is constituted of two to three layers, and a pattern layer 4 on which characters and the like are drawn by gravure ink is formed on a lowermost layer. A shrinkable film 1 as a base film is formed on the pattern layer 4. A vinyl chloride film is used for the shrinkable film. A transparent ink layer 2 is formed on an uppermost layer. An antibacteria agent 3 of fine particle shape is blended in the transparent ink layer 2. The antibacteria agnet is the powder of an antibacterial inorganic material composed of alumino silicate of an alkaline or an alkaline earth metal in which silver, copper and zinc of antibacterial properties are contained.  As the antibacterial film is formed only on the surface of a product by the antibacterial film, a large amount of the antibacteria agent is not required in the manufacture to lower the manufacturing cost.

Abstract: PURPOSE:To provide a trimming press which provides a reduction in size and simplification of a press body without decreasing working capacity and working accuracy by unitizing thoroughly the entire part of a blanking die provided with a pair of upper and lower punches and a die independently from the press body. CONSTITUTION:A lift element 207 which acts on a punch holder 203 is acuated when the blanking die 200 is moved to a place apart from the table 103 of the press body 100. The holder 203 can be moved upward as desired from the height at which the bottom end of the punch 201 is positioned in proximity to the top surface of the die 202. The extent of the upward movement of the holder 203 in this stage is determined by the lift of the element 207 and the height of a guide post 205 and can be therefore made fairly large. The height of the open spacing between the punch 201 and the die 202 can be made considerably larger than the case of the conventional press. The removal of the trimmed product right after working and the removal of the burr remaining on the die 202 in addition to the supply of the forged product requiring trimming onto the die 202 are consequently executed with ease by utilizing the wide open spacing between the punch and the die.
