Claims
- 1. A method of manufacturing a covering for an infusion bottle by means of a deep drawing tool having a deep drawing stamp, the covering comprising a cap adapted to be flanged at its lower edge for gripping a neck of the bottle, the cap having a hole with a foil covering for the formation of a puncture region at the top of the cap, the method comprising steps of:
- placing a first strip of deep-drawable material and a second strip of deep-drawable material in coinciding position beneath said stamp;
- advancing said stamp, via a deep drawing, against said first strip and said second strip to transform both of said strips into said cap.
- 2. A method according to claim 1, wherein said deep-drawing step further comprises a step of
- cutting an edge side in both of said strips at a location of said lower edge of said cap to produce an edge burr formation serving as an adherence attachment in said cap between said first and said second strips.
- 3. A method according to claim 1, wherein said stamp is a first stamp and said tool further comprises a second stamp, the method further comprising a step of:
- prior to said deep-drawing step, employing said second stamp for punching said hole in said first strip.
- 4. A method according to claim 3, wherein said deep-drawing step further comprises a step of
- cutting an edge side in both of said strips at a location of said lower edge of said cap to produce an edge burr formation serving as an adherence attachment in said cap between said first and said second strips, said second strip serving as said foil covering.
- 5. A method according to claim 4, wherein,
- in said placing step, said second strip is located between said first strip and said first stamp.
- 6. A method according to claim 1, wherein, in said placing step, said second strip is located between said first strip and said stamp.
- 7. A method according to claim 6, wherein said deep-drawing step further comprises a step of
- cutting an edge side in both of said strips at a location of said lower edge of said cap to produce an edge burr formation serving as an adherence attachment in said cap between said first and said second strips.
- 8. A method of manufacturing a covering for an infusion bottle, the covering comprising a cap having a hole with a foil covering serving as a puncture region, the method comprising the steps of:
- punching said hole in a first strip of a first deep-drawable material;
- providing a second strip of a second deep-drawable material to serve as said foil covering;
- locating said first strip relative to a stamp with said hole in front of said stamp;
- placing said second strip between said first strip and said stamp; and
- advancing, via a deep-drawing, said stamp against both of said strips to form said cap.
- 9. A method according to claim 8, wherein said deep-drawing step further comprises a cutting of both of said strips at locations corresponding to an edge of said cap to produce a burr for securing said first material to said second material within said cap.
