Definitions
- the present invention relates to a method for manufacturing of pull-through seals according to the preamble of claim 1.
- pull seals are made of plastic manufactured by spraying.
- Such a pull-through seal has a base body in construction with attached closure body and a protruding from the base body tongue leading away, Tip inserted through the closure body when in use can be.
- the tongue usually points Restraint in the form of knobs or teeth, which is the passage of the tongue through the closure body allow in one direction. In the opposite But direction is by arranged in the closure body Blocking agents that act on the tongue restraint act, a retraction of the tongue impossible.
- Pull-through seals are so-called one-way means, i.e. you can usually only used once and the Closure can only be released by destruction.
- the object of the present invention was now to a process for the production of pull-through seals To find plastic that allows practically any To produce dimensions of tongues without additional effort.
- the tongue of the pull-through seal in the Extrusion processes can advantageously be practically any Dimensions, especially in length, can be achieved.
- Instead of manufacturing of many different molds for each one needed Dimensioning can be done with a single extrusion tool and the use of a standardized body practically all requirements for the pull-through seals a smaller one compared to the conventional method Effort to be covered.
- Another advantage is the possibility of using it of polyethylene as plastic for the manufacture of the Pull-through seal, since the strength is achieved through the stretching process is increased by aligning the plastic molecules and practically the same values as with conventional pull-through seals made from polyamide at a much lower cost.
- FIG. 2 The production process according to the invention is shown schematically in FIG a pull-through seal 1 made of plastic.
- the tongue of the Pull seal made by preferably a trapezoidal Profile 2 is extruded, which immediately after the extrusion is profiled.
- the cross section of the profile strand 2 is shown in FIG. 2.
- the profiling is preferably carried out via a profiled Wheel 3, which is preferably on the short top of the extruded profile strand 2 is pressed on in a rolling manner.
- a rack-shaped profile strand 4 is generated, as shown in Figure 3.
- the profile surveys 4 ' preferably have a regular distance A.
- This profile strand 4 then becomes a stretching process 5 supplied, which the length of the profile strand 4th preferably doubled. Again, this can be advantageous done continuously, or alternatively for those already Profile pieces cut to the required dimension can be applied individually.
- the stretching process 5 the profiled profile strand 4 leads on the one hand to a Alignment of the plastic molecules, which increases the strength.
- This can advantageously be polyethylene as a plastic be used, which is cheaper than that Polyamide conventionally used in the pressure spray process, but practically the same strength values due to the stretching how the polyamide achieved. This will be preferred by stretching the profile at a temperature of 60 ° C reached. Another of these procedures lies in that the material practically without tensile load Elongation breaks when the breaking limit is reached, which is an invisible Manipulation of the pull-through seal practically impossible.
- the base body 8 can, for example, in a conventional manner be produced by pressure spraying and thereby either in one piece with a closure body 9 be equipped, or this will be in an additional Process step similar to the tongue 7 also separately on the Base body sprayed on.
- This latter process step in turn preferably enables an increased design Freedom in the design of pull-through seals 1 by the closure body 9, for example, in several parts and especially not only from one material but from one Composition of different materials can exist. So can in particular a closure body 9 with a metal insert be used, which has an increased tensile strength and Tamper-evident.
- Figure 5 is the supervision shown on a pull-through seal 1 produced in this way.
- a pull-through seal 1 produced in this way has a very large high security against manipulation, since after manipulation, such as cutting the tongue 7, this Manipulation does not simply undo or invisible can be made. If preferably polyethylene is used an interface cannot simply pass through invisible bonding can be connected again. When using the material simply melts from heat and can not simply welded as a stable connection.
- the manufacturing process presented can thus be universal for the production of pull seals 1 with different Tongue lengths and, if necessary, different closure bodies 9 are used and require only a minimal Number of tools. It is particularly advantageous that not for each different length of tongue required an own, special injection mold has to be manufactured and thus the procedure is based on the cost-effective and economical production of small quantities in special sizes suitable or designs. In addition, a cheaper one Plastic like polyethylene with undiminished Strength values of the pull-through seal 1 are used, than this in conventional injection molding due to the use of polyamide.
