Two-part plastic blank set

Abstract

The invention relates to a two-part plastic blank set for producing an active substance applicator for storing a unit dose of an active substance preparation and for dispensing said unit dose into thehuman nose, wherein the plastic blank set comprises a lower part and a top part separated from the lower part, wherein the lower part has a receiving space molding enclosed by a sealing edge and a one-part molded-on application tube extends from the receiving space molding, which application tube at the free end thereof is closed by a closure integrally molded in one piece over an attachment element, wherein the attachment element has a wall thickness of 0.1-0.5 mm, preferably 0.2-0.3 mm, and wherein the top part has a size in order, when laid on the lower part, to completely cover the holding space molding of the same, and has a sealing edge which can be connected in a sealing manner to the sealing edge of the lower part, wherein an attachment platelet extending from the respective sealing edge, preferably in the same plane as the sealing edge, is integrally molded on the top part or on the lower part. The invention further relates to an active substance applicator that can be produced therefrom.

Description

technical field [0001] The present invention relates to a set of two-part plastic blanks, preferably for the production of a pharmaceutical applicator for storing a unit dose of pharmaceutical formulation and administering the unit dose to the nose of a human; and to the production thereby drug applicator. Background technique [0002] In some pharmaceutical formulations or medicaments for use in the human or animal body, precise dosage is critical. In order to ensure that the user receives an accurate dosage, dosage units are provided which contain a desired amount of a pharmaceutical formulation and which, when used, deliver exactly that desired amount to the human or animal body. Furthermore, drug applicators are known which can only be used once but have a dual function: firstly, they contain predetermined doses of drug preparations; secondly, they are used not only to deliver the drug preparations, but also to Deliver in desired amount to desired location. Drug appli...

AI Technical Summary

Problems solved by technology

[0006] In addition, it is apparent that during shipping, the attachment member between the applicator tube and the seal is often bent so that leaks can occur

[0007] Furthermore, drug applicators known in the prior art are only capable of delivering drug formulations with a very low viscosity, such as a viscosity not exceeding 1,000 mPa·s

It is also often the case in the prior art that satisfactory dose consistency cannot be achieved, for example when using single-dose drug applicators that are supposed to give a constant dose every day
