Problems solved by technology
The disadvantage of this solution is that the molded closure cap can only be removed with increased effort from the hollow profile for holding the tab at the predetermined tear line
However, this solution requires an expensively constructed hollow profile

Embodiment Construction
[0032] figure 1 A sectional view of a preferred embodiment of the injection molding tool according to the invention for producing closure caps is shown in the open state. The injection molding tool according to the invention firstly comprises a tool frame 01 in which, firstly, the outer molded part 02 is enclosed. The outer profile 02 serves to shape the outer contour of the closure cap to be produced. The cylindrical hollow molding 03 for molding the closure cap body can be seen in the illustration shown. The cylindrical hollow profile 03 has a profile 04 for forming a grip surface on the surface of the closure cap to be produced.
[0033] Furthermore, the injection molding tool comprises an inner core 06 for forming the inner contour of the closure cap to be produced. The inner core 06 has essentially a cylindrical shape and primarily has a structure for forming the thread of the closure cap to be produced (in Figure 5 shown in ).
[0034] The illustrated cross-sectio...

The invention relates to a sealed cap provided with a guard ring and an injection molding tool and method for producing the same. According to the injection molding tool used for producing a sealed cap, in the production of the sealed cup, a guard ring is formed on the sealed cap main body into one piece via one ore more holding connecting sheets. The injection molding tool firstly comprises an external forming piece used for forming an external contour of the sealed cap and a core piece used fro forming the internal of the internal contour of the sealed cap. The core piece is provided with sections used for forming the internal contour of the sealed cap main body and sections used for forming the internal contour of the guard ring, in a transition region between the sections forming the sealed cap main body and the sections forming the guard rings, the core piece is provided with one or more hollow forming parts used for forming one ore more holding connecting sheets. According to the injection molding tool in the invention comprising at least one sliding piece provided with a receiving surface, the sliding piece can slide to one or more hollow forming parts via the receiving surface.
Description
technical field [0001] The invention relates to an injection molding tool for producing closure caps with an integrally formed securing ring. Furthermore, the invention relates to a method for producing such a closure cap and to such a closure cap. Background technique [0002] It is known from the prior art (for example from DE 42 07 996 C2, WO 93 / 00270 A1, DE 36 22108 A1 and DE 42 14 151 A1) that a pre-determined tear for the safety ring is formed on the closure cap by a cutting process Line (Sollrei βlinie). The disadvantage of this solution is that an additional work step is required for this after the casting of the closing cap. [0003] From WO 94 / 14672 A1 it is known to hot mold the securing ring onto the closure cap by means of an additional work step. [0004] It is likewise known from the prior art, for example from DE 32 27 510 A1, DE 32 06 245 A1 and DE 8220 978 U1, to arrange a plastic ring as a safety ring on a closure cap made of metal. The plastic ring is...
