  • the sealing can be done by heat, high frequency radiation or ultrasound and by means of sealing tools. Typical sealing temperatures are from 100 to 300 ° C and expedient from 150 to 250 ° C.
  • the pressure of the sealing tools can be, for example, from 10 to 400 kg / cm2 and expediently from 40 to 150 kg / cm2.
  • the sealing times can be from 0.2 to 3 seconds and expediently from 0.4 to 2 seconds.
  • the sealing seams made under these conditions can be e.g. peel, peel or peel slightly to form a cohesive or adhesive break. It can also be provided that the cover segments cannot be completely peeled off or peeled off by applying the weakening lines or dividing lines and / or sealing seams of different strengths.
  • lid segments of the individual compartments release the compartment and its contents, but stick to the bottom part with part of the sealed seam.
  • this can reduce a waste problem, namely that the lid segments are thrown away individually, or the compartments can be reclosable or at least re-coverable.
  • the push-through pack on the sealed lid can contain a tear-off tongue or tear-open tab on each lid segment.
  • a corner of a push-through pack is indicated by way of example, which is to be sealed against the polypropylene base part with an opaque, heat-sealable polypropylene film as cover material with a thickness of approximately 70 to 80 ⁇ m.
  • the dashed line (A) is intended to mean an incision from the cover film side through the cover film to a minimal extent in the e.g. 300 ⁇ m thick bottom film into it - see also Fig. 2 (B).
  • the circular average of the lidding film e.g. with a Schober rotary punch for rotary machines or with a steel punch for punching machines runs around the bowl, from (a) to (b).
  • a partial bottom film (1) forms a depression (2) and a web area (3).
  • the bottom part film can e.g. be a 300 ⁇ m thick PP film.
  • a cover material in the form of a cover film (4) is sealed to the web areas.
  • the cover film (4) can e.g. represent a 70 to 80 ⁇ m thick film made of polypropylene, which optionally carries a ceramic barrier layer against the inside and a heat sealing lacquer (5) on the barrier layer.
  • a tablet (6) is in the recess (2). The arrow indicated indicates the direction of pressure when the tablet (6) is squeezed out.
  • the heat sealing lacquer at point (d) can begin to separate to split or peel inside
  • the peeling effect runs up to the cut (B), then the membrane bursts and the tablet can be removed upwards.
  • the described design can be installed on any form, fill and seal machine of today's design.
  • the cut which represents the dividing line, can be made after the sealing by means of a perforating station and can thus lie exactly around the bowl.
  • a web width (f) of, for example, 1.5 mm gives adequate adhesion.
  • the pack shown as an example cannot be peeled from the outside, since it is a smooth die cut and there are no possibilities to take a peeling bag.
  • Fig. 3 is a view of a section of an open blister pack.
  • the recess (2) for receiving the tablet was pressed in from below, whereupon the cover film (4) flakes off along the sealing seam up to section B and the tablet (6) can be removed. Since the section B does not surround the entire circumference of the recess (2), the membrane (e) remains on the cover film (4) in the area between (a) and (b).
  • the present invention also relates to the use of packaging according to the invention for accommodating different fill goods in separate compartments and for separately removing the different fill goods.
  • the packaging is suitable for holding fillings of all kinds, in tablet-like form and firm consistency, but in particular for holding tablets, dragees, hard and soft gelatin capsules, sweets such as candies, chewing gum, chocolate etc., tablet-like products from the diagnostic area , Therapeutics and medical aids.
  • the tablets can in particular be luxury foods, cosmetic products or pharmaceutical preparations.
  • the packaging can be sterilized, pasteurized or treated aseptically, for example in the range of standard sterilization conditions at 121 ° C - 130 ° C, 2.2 bar - 3.5 bar and for 30 seconds to 30 minutes.
  • the filled packaging can be stored, chilled or frozen at room temperature.
  • each lid segment can be used individually, e.g. according to the removal order.
  • Other uses are e.g. Packs for portion consumption or assortment packs.
