[0003] SUBSTANCE CHAMBER AND INHALATOR COMPRISING A SUBSTANCE CHAMBER

[0004] The present invention relates to an improved inhalator, inhalator parts and a method of manufacturing an inhalator.

[0005] BACKGROUND

[0006] Various types of inhalators are known and may be used to substitute the use of cigarettes. However, such inhalators comprise various drawbacks. For example, some inhalators require use of heat, e.g. provided by electrical heating, to vaporise the substances inside the inhalator. Also manufacturing of inhalators are often complex and time-consuming. Furthermore, the weight of a typical inhalator is much higher than a conventional cigarette. There is therefore also a desire to reduce the weight of inhalators to closer resemble the feel of a conventional cigarette.

[0007] SUMMARY

[0008] It is an object of the present disclosure to facilitate an improved inhalator which is easier and faster to manufacture. Particularly, the present disclosure provides an inhalator comprising a plurality of inhalator parts.

[0009] Accordingly, a substance chamber for an inhalator, such as an inhalator comprising the substance chamber and an evaporation chamber, is disclosed. The substance chamber comprises a first cylindrical shell extending in a longitudinal axis from a first end to a second end. The substance chamber has an inner diameter, an outer diameter, and a wall thickness. The wall thickness is half of the difference between the outer diameter and the inner diameter.

[0010] The substance chamber comprises a first sealing body and a second sealing body. The first sealing body and the second sealing body are movably arranged inside the first cylindrical shell. The first cylindrical shell, the first sealing body and the second sealing body form a substance compartment containing a substance, such as at least a primary substance. The substance, such as the primary substance, is preferably a liquid substance.

[0011] Often inhalators are manufactured as a single tube where each component or part of the inhalator is inserted into the tubing in a specific order. This method of manufacturing an inhalator is complex and time-consuming.

[0012] Furthermore, the tube which the component is inserted into constitutes a weight which is higher than the conventional cigarettes. There is therefore a desire to reduce the weight of inhalators to closer resemble the feel of a conventional cigarette. P2542PC00
