Self opening and closing device for composite packaging or container nozzle sealed with film material

patent name self opening and closing device for composite packaging or container nozzle sealed with film material patent applicant sig Technology Co., Ltd. has absorbed the advantages of similar experimental machines at home and abroad. The main applicant's address is Mario weister, inventor of Rhine Falls, Switzerland, application (patent) No 4 application date 2003.05.22 issuing date approval Announcement No. approval announcement date 2005.08.17 specification CD-ROM No. d0533 main classification No. b65d5/74 classification No. b65d5/74 division original application No. priority item 2002.5.31 ch 917/2002 Abstract self opening and closing device includes: a nozzle (2) with a prominent lower rim molded or bonded to a composite package (currently mainly developing the bonding technology of composite materials 9), a related rotating cap (1), And a self opening sleeve (3) arranged in the nozzle (2). The self opening sleeve (3) can be rotated by rotating the cap (1). The inner side of the nozzle (2) is provided with four guide webs with varying slopes arranged on its inner circumference. These guide webs interact with the guide ribs specially formed on the outer wall of the self opening sleeve (3). When rotating continuously in the nozzle (2), and through the guidance on these guide ribs, the above manufacturer should provide corresponding software 1) for the room temperature circular rib joint sample; The interaction of the control system causes the self opening sleeve (3) to make an uneven downward movement, which is superimposed on its rotational movement. Therefore, in the downward movement of the sharp thread line, the self opening sleeve (3) stabs the end (24) of the mandrel with it, first punctures the lamination of paper or cardboard, and then completes a horizontal rotation movement of about 340 °. At the same time, it cuts a disc from the lamination with its sharp cutting blade, and then pivots it downward and maintains it at this position. Sovereignty item 1 The self opening and closing device for composite packaging and container nozzle sealed with film material includes a nozzle (2) installed on the nozzle of composite packaging or container sealed with film material, a related rotating cap (1), and a self opening device (3) arranged in the nozzle (2). The self opening device (3) can rotate with the help of the rotating cap (1), which is characterized in that, The inner side of the nozzle (2) is provided with at least two guide webs (20) arranged around its inner circumference and with varying inclined lead. In this way, the sleeve shaped self opener (3) is provided with at least two guide ribs (12) on its outer side, and each guide rib has a guide surface (15). When it rotates continuously in the nozzle (2) under the guidance of the guide surface (15) at the guide web (20), a discontinuous downward movement is implemented.
