Packaging structure and method for sterile packaging containers for substances for medical, pharmaceutical or cosmetic applications and methods for further processing of containers using this packaging structure
A method for sterile packaging of a plurality of containers is provided that includes: providing a carrier in which a plurality of receptacles are formed, the receptacles being formed by a closed bottom and a circumferential side wall, the upper ends of the receptacles, which are opposite to the respective bottom, are open and circumferential connecting webs are provided at the upper ends; placing the containers in the receptacles; providing a gas-impermeable protective foil; bonding the protective foil along the connecting webs with the upper surface of the carrier to package all the receptacles with the containers accommodated individually therein; and sterilizing the receptacles with the containers accommodated therein and/or the inner volumes of the containers by a gas flowing into the receptacles and/or into the inner volumes of the containers through at least one gas-permeable portion.
1. A packaging structure for sterile packaging of a plurality of containers for medical, pharmaceutical or cosmetic applications, which are accommodated in the packaging structure and sterile packaged against the environment, comprising:
a carrier in which a plurality of receptacles are formed;
a plurality of containers which are each accommodated individually in the receptacles; and
a gas-impermeable protective foil, which is connected to an upper surface of the carrier for sealing the receptacles sterile against the environment, wherein
the receptacles are each formed by a closed bottom and a circumferential side wall,
upper ends of the receptacles opposite to respective bottoms are open,
circumferential connecting webs are provided at the upper ends of the receptacles, adjacent receptacles being connected to one another via the connecting webs,
a protective foil is connected to the connecting webs along the connecting webs,
at least one gas-permeable portion associated with the receptacles is formed in the protective foil and as a portion of the protective foil, so that the receptacles of the packaging structure can be sterilized by a gas flowing through the at least one gas-permeable portion,
the connecting webs are configured and connected with the protective foil in such a manner that individual packaging subunits can be severed by severing along the connecting webs, each packaging subunit having one receptacle in which a single container is accommodated and sealed sterile against the environment by the protective foil, and
all the receptacles of the packaging structure are each packaged individually, sterile and sealed against the at least one gas-permeable portion by bonding the protective foil along the connecting webs so that an interior of the receptacles does not communicate with the at least one gas-permeable portion.
2. The packaging structure according to claim 1 , wherein each receptacle is associated with one gas-permeable portion.
3. The packaging according to claim 2 , further comprising a recess that extends from the interior of the respective receptacle to the associated gas-permeable portion in the upper surface of the carrier and/or in a lower surface of the protective foil, which is plugged along the connecting webs after bonding the protective foil so that the receptacles are each sterile packaged and sealed against respective associated gas permeable portion.
4. The packaging structure according to claim 1 , wherein
the at least one gas-permeable portion of the protective foil is formed of a meshwork made of synthetic fibers or of a portion having a grid-like structure with openings and
wherein the at least one gas-impermeable portion of the protective foil is formed of a plastic or metal foil or a composite material from these materials.
5. The packaging structure according to claim 4 , wherein the meshwork made of synthetic fibers is a meshwork of polypropylene fibers.
6. The packaging structure according to claim 1 , wherein the packaging structure is formed of a material which is resistant to hydrogen peroxide vapor.
7. The packaging structure according to claim 1 , further comprising weakening regions that extend along the connecting webs along which the connecting webs can be separated mechanically so that the individual packaging subunits can be severed by severing along the weakening regions of the connecting webs.
8. The packaging structure according to claim 7 , wherein the weakening regions extend in a middle along the connecting webs.
9. The packaging structure according to claim 7 , wherein the weakening regions are formed as continuous, linear recesses or as a series of point-like recesses.
10. The packaging structure according to claim 9 , wherein the weakening regions are formed by one of mechanical carving, embossing, and laser treatment of the material of the connecting webs.
11. The packaging structure according to claim 1 , wherein
the at least one gas-permeable portion of the protective foil is formed of a meshwork made of synthetic fibers or of a portion having a grid-like structure with openings and
wherein the at least one gas-impermeable portion of the protective foil is formed of a plastic or metal foil or a composite material from these materials.
12. The packaging structure according to claim 11 , wherein the meshwork made of synthetic fibers is a meshwork of polypropylene fibers.
13. The packaging structure according to claim 1 , wherein the packaging structure is formed of a material which is resistant to hydrogen peroxide vapor.
14. The packaging structure according to claim 7 , wherein
the at least one gas-permeable portion of the protective foil is formed of a meshwork made of synthetic fibers or of a portion having a grid-like structure with openings and
wherein the at least one gas-impermeable portion of the protective foil is formed of a plastic or metal foil or a composite material from these materials.
15. The packaging structure according to claim 14 , wherein the meshwork made of synthetic fibers is a meshwork of polypropylene fibers.
