Powder blowers. -A powder blower, comprising a compressible box like container formed of material which is flexible but substantiallv inextensible, is provided with an internal discharge tube rigidly attached to the inner wall of the container as distinct from a discharge tube passing through the container wall so as to .extend both externally and internally. In combination therewith an internal partition may be provided which divides the container into a reserve compartment and a relatively small discharge compartment. The discharge tube surrounds a perforation or a perforable marked spot in the container wall. The container, preferably made of cardboard, is of box form with a lid 2, the top 4 and bottom 3 being slightly domed to permit of a bellows action and the junction 13 between lid 2 and bottom portion 1 being sealed by a paper covering. The internal discharge tube 10, preferably cut obliquely at the end 12, is mounted in a reinforcement 11. A cardboard partition 6 bent approximately to a right angle 7 is secured to the sides and bottom of the container by flaps 8, 16. Attached to the top thereof is a flap 9 above which a small space allows passage of powder. Openings 14 in the upright walls of the partition are also provided for this purpose. In an alternative form, a plain baffle or partition is provided with a small sunken portion into which the inner end of the discharge tube dips. The Provisional Specification describes a form in which the top portion 9 is formed by overlapping flaps on the upright partition 6 and also states that the container may be of cylindrical, spherical, rectangular, irregular or other shape.
