Abstract
The present invention relates to packaging water or solvent based formulations, in particular to those formulations which are prone to skinning. The invention comprises a container that is adapted to contain such a formulation in which an anti-skinning layer is located between at least a portion of an internal surface of the container or a lid and the formulation.
Claims51
A container adapted to contain a water based or solvent based formulation, the container including
- an anti-skinning layer located on at least a portion of the internal surface of the container, wherein the anti-skinning layer is capable of retaining a layer of the formulation without excluding the formulation vapour in the container from contacting the formulation.
A container adapted to contain a water based or solvent based formulation, including
- a container sealing means including an anti-skinning layer located on at least a portion of the internal surface of the sealing means, wherein the anti-skinning layer is capable of retaining a layer of the formulation, without excluding the formulation vapour in the container from contacting the formulation.
A sealing means adapted to substantially control skinning of water based or solvent based formulations, in which the sealing means includes an anti-skinning layer, in which the layer is located on at least a portion of the inner surface of the sealing means, wherein the anti-skinning layer, when in use on a container adapted to contain a water-based or solvent based formulation, is capable of retaining a layer of the formulation, without excluding the formulation vapour in the container from contacting the formulation.
A container including a sealing means, in which the container is adapted to contain a formulation prone to skinning by loss of water or solvent wherein at least a portion of the internal surface of the container in proximity with the ullage space of the container has a means capable of retaining a layer of the formulation, without excluding the formulation vapour in the container from contacting the formulation.
