Abstract
A dispenser for an active substance which is positioned in the region of the nostrils for inhalation and is used for the evaporation of active substances of a medicinal, paramedicinal, and flavor-therapeutic types. The dispenser includes a flat dish that is made of absorbent, air-penetrable material and is surrounded by a circular edge. The dish is covered by a lid that is pasted on the edge. Loosely poured micro-capsules containing an active substance are contained in a closed chamber formed between the lid and the dispenser. A central area of the outside of the lid is covered with a tampon-like adhesive layer which, in turn, is covered by a peelable siliconized protective foil. A process and a production line for the manufacturing of the dispenser of active substances are described.
Claims18
A method for the manufacture of a dispenser of active substances, said method comprising:
- receiving a first layer of absorbent air penetrable material,
- deforming the layer to form at least one dish-like deformation,
- placing micro-capsules in the deformation,
- pasting a second layer on the first layer to form a lid,
- providing an adhesive layer on the second layer,
- placing on adhesive layer a peelable protective foil that covers the entire second layer and which upon peeling the adhesive layer in an adhesive state,
- punching the peripheral area of said dispenser to separate the dispenser from said layers,
- subjecting the dish-like deformation at least, before the placing of micro-capsules on it, until the second layer is pasted over it, to an indraft that flows through the first layer within the area of the deformation,
- wherein the second layer located above the deformation is provided with the adhesive layer the surface area of which is smaller than the outline of the dispensers of active material, in such a way that the punched peripheral sections forming the dispensers of active substances will be located in zones that are free of adhesive layers.
A production line for the manufacture of a dispenser of an active substance, said production line comprising:
- a screw-press for forming dish-like deformations in a first layer of absorbent, air-penetrable material,
- a filling device for placing micro-capsules in the dish-like deformations,
- a first lining device linked to said filling device for pasting-over the filled deformation with a covering second layer,
- a device for the application of an adhesive layer to the outside of the covering second layer,
- a second lining device for covering the adhesive layer with a silicon-like, peelable protective foil that covers the entire second layer and which upon peeling leaves the adhesive layer in an adhesive state,
- a punching device for the automatic removal of the finished dispenser of active material,
- bearer plates movable in a direction of flow from said screw-press to said removal device for receiving the dishlike deformations in bearer beds that are air-penetrable, and
- a pneumatic device for the imposition of an indraft to the undersides of said bearer beds,
- wherein the device for the application of the adhesive layer in the outside of the covering second layer is constructed in such a way that the surface area of said adhesive layer is smaller than the outline of the dispenser of active material, so that punched peripheral sections forming the dispensers of active substances will be located in zones that are free of adhesive layers.
