Embodiments of the pouched unit and the method according to the invention will be described by way of example only, with reference to the accompanying schematic drawings in which corresponding reference symbols indicate corresponding parts, and in which:
The
The secondary part 6 comprises a message 7 with user information for the user. The weaker area 9 allows that the additional water soluble material 5 of the secondary part 6 of the pouch 4 can manually be removed before the main part 3 of the pouch 4 and its dose of substance 2 is used. This way, the message 7 can be provided to the user while preventing that the additional water soluble material of the secondary part 6 negatively affects the use of the main part 3 and its dose of substance 2.
The pouch 4 has a lower tensile strength at the weaker area 9 when compared with the main part 3 and the secondary part 6. This facilitates the manually separation of the secondary part 6 from the main part 3.
The secondary part 6 extends away from the main part 3. This facilitates the addition of the message 7 to the secondary part 6.
The substance 2 in the main part 3 of the pouch 4 is a detergent material, more specifically a laundry detergent. The message 7 comprises user instructions for the user of the pouched unit 1. The message 7 may comprise different information, such a warning for toxic materials. The message 7 may comprise a text or a symbol 8. The message 7 is provided on the secondary part 6 by a colourant 11. The water soluble material 5 is transparent.
The water soluble material 5 is a polyvinyl alcohol (PVOH). Other types of water soluble materials may be used.
The water soluble material 5 has been subjected to a weakening treatment at the weaker area 9. The weaker area 9 comprises multiple incisions 10 in the water soluble material 5. In another example, the weaker area 9 comprises one incision 10 in the water soluble material 5.
The pouch 4 is only formed by the water soluble material 5. This means that the pouch 4 itself only contains the water soluble material 5. It is possible that another material is provided on the pouch, such as a colorant.
The pouch 4 is formed by two interconnected films 16A, 16B of the water soluble material 5. The two films 16A, 16B are transparent. In other examples, the water soluble material 5 is translucent, or opaque. The water soluble material 5 may coloured.
