ABSTRACT:
A dispenser for solvent wetted towelettes in the form of a continuous band that is perforated at intervals along its length to define separate towelettes. The dispenser comprises a container 12, a first closure member 16 having a skirt 22 that is received in an annular groove 24 in the container 12, and a lid 20 that screw engages the container 12. When the lid 20 is screwed on to the container 12 a first set of sealing formations 22 to 26 between the first closure member and the container and a second set of sealing formations 28 to 31 between the lid and first closure member are urged into sealing engagement. A further set of sealing formations 32, 34 adjacent a dispensing opening 18 are also urged into engagement. The dispenser has good sealing properties and is therefore suitable for use with volatile solvents such as acetone. Novel dispensing formations are also disclosed.
