Definitions
- the invention relates to a method for producing a sealed vessel. Furthermore, the invention relates to a vascular closure and a vessel that is closed with the vascular closure.
- Grainy or moisture-sensitive foods e.g. powdered milk, beverage preparations, or instant coffee are often stored in a container sealed with a plastic closure.
- an opening of the container is often additionally provided with a film, which is removed and disposed of by a user when the food (preparation) is first removed.
- a drink or food can be prepared by adding water or another liquid to the food (preparation).
- the food (preparation) can be removed in portions from the container and the container can be closed again with the plastic closure after removal.
- the recycling process of the foil and the plastic closure is complex.
- an aroma and moisture barrier after removing the foil and resealing with the plastic seal is not optimal.
- One object of the invention is to provide a method by which a closed vessel can be produced, in which case a moisture-sensitive filling can be stored in the vessel and the vessel and the associated vessel closure can be recycled in an improved manner.
- a further object of the invention is to provide a vessel closure which can close an opening of a vessel and which is suitable for a vessel for storing moisture-sensitive contents, the vessel closure being more recyclable.
- Yet another object is to provide a vessel with a vessel closure, in which case a moisture-sensitive filling can be stored in the vessel and the vessel closure and the vessel can be recycled in an improved manner.
- Yet another object is to provide a vessel closure for a vessel and a vessel closed with the vessel closure, wherein a filling can be stored in the vessel and a user can reseal the vessel in an improved manner when the user removes filling material from the vessel in portions.
- the object is achieved by a method according to claim 1, a vessel closure according to claim 12 or a vessel according to claim 13.
- a vessel seal can have a sealing element be provided or be provided.
- the sealing element may comprise a polymer composition.
- the polymer composition can contain at least one polymer, eg a polyolefin.
- the Shore A hardness of the polymer composition can be 80 at most. The Shore A hardness can be determined according to DIN ISO 7619 with a holding time of 15 s and a temperature of 23 °C.
- a vessel with an opening can be provided. The opening of the vessel can be surrounded by a vessel mouth. The vessel closure can be applied to the vessel mouth in such a way that the opening of the vessel is closed.
- the sealing element can have a maximum temperature of 80° C. while the vessel closure is being applied to the vessel mouth.
- a vessel closure with a sealing element can be or can be provided.
- the sealing element may comprise a polymer composition.
- the polymer composition may contain at least one polymer, e.g., a polyolefin.
- the Shore A hardness of the polymer composition can be 80 at most. The Shore A hardness can be determined according to DIN ISO 7619 with a holding time of 15 s and a temperature of 23 °C.
- a vessel with an opening can be provided. The opening of the vessel can be surrounded by a vessel mouth. An inert gas can be introduced into a headspace of the vessel. The vessel closure can be applied to the vessel mouth in such a way that the opening of the vessel is closed by the vessel closure.
- the inert gas may be introduced primarily or exclusively into the headspace of the vessel.
- a section of the sealing element When the vessel closure is applied to the vessel mouth, a section of the sealing element can come into contact with a section of the vessel mouth. In the closed state, the sealing element (a portion of the sealing element) can contact the vessel mouth (a portion of the vessel mouth).
- the vessel closure can be applied to the vessel mouth at ambient temperature.
- the vessel closure can be applied to the vessel mouth without steam, in particular steam, being used.
- the vessel closure can be applied to the vessel mouth without a temperature treatment.
- the sealing element can be ring-shaped or annular disk-shaped or disk-shaped.
- the sealing element can be arranged at least partially in a (circumferential) depression in the vessel closure.
- the polymer composition can be a thermoplastic elastomer.
- Polymer composition can be a thermoplastic elastomer composition
- the sealing element can comprise the polymer composition or consist of the polymer composition.
- the vessel closure can be a screw closure.
- the vessel closure can be a rotary cam closure.
- the vessel closure can be screwed onto the vessel mouth.
- the vessel can be a glass vessel.
- the vessel can comprise glass or consist of glass.
- the vessel closure can be a metal closure.
- the vascular occlusion can include metal or consist of metal.
- the outer diameter of the vascular occlusion can be at most 120 mm.
- the outer diameter of the vessel closure is preferably no more than 100 mm or no more than 90 mm.
- the outside diameter of the vascular occlusion is between 30 mm and 120 mm or between 40 mm and 100 mm.
- a maximum volume of 5 L preferably a maximum of 3 L, particularly preferably a maximum of 1 L, can be accommodated by the vessel.
- a granular filling material can be introduced into the vessel, in particular a granular foodstuff or a granular food preparation.
- a powdered filling material can be introduced into the vessel, in particular a powdered foodstuff or a powdered foodstuff preparation.
- milk powder, a beverage powder, a dried spice, a hygroscopic food, instant coffee, dried vegetables, dried meat, dried fish, or dried fruit can be placed in the vessel.
- a moisture-sensitive product (moisture-sensitive food or moisture-sensitive food preparation) can be placed in the vessel.
- a moisture-sensitive product can spoil more quickly or lose flavor or change its consistency through contact with moisture.
- a filling material (food or food preparation) with a moisture content of less than 10% by weight, in particular less than 8% by weight, preferably less than 5% by weight, particularly preferably less than 3% by weight, can be placed in the vessel. , to be introduced.
- the vessel in particular the headspace of the vessel, can be pressurized with an inert gas, in particular with nitrogen.
- the pressure in the sealed vessel can be above ambient pressure (1 bar) at room temperature.
- the vessel can be sealed with the vessel closure under an inert gas atmosphere, in particular a nitrogen atmosphere.
- the vessel can be filled with the filling material under an inert gas atmosphere, in particular a nitrogen atmosphere.
- the vessel occlusion can be applied to the vessel mouth with a torque of no more than 9.0 Nm (80 inch lbs), preferably no more than 7.9 Nm (70 inch lbs), more preferably no more than 6.8 Nm (60 inch lbs), even more preferably maximum 5.6 Nm (50 inch lbs).

If the height hs is too low, there is a risk of the sealing element 3 being cut through, as a result of which the tightness of the closed vessel 5 may be impaired. If the height hs is too great, the tightness of the closed vessel is impaired since the contact surface between the upper end 4 of the vessel mouth 5a and the sealing element 3 is not sufficiently large. A fitting impression of the upper end 4 of the vessel mouth 5a in the sealing element is desirable.
