Stick for applying a liquid

Claim 1

A package which is manually separable into a plurality of individual cleaning sticks for application of a volatile cleaning liquid to a surface to be cleaned comprising: a first thermoplastic sheet having a plurality of spaced parallel elongated troughs formed therein, filled with volatile cleaning liquid, each trough including at one end a reduced cross section dispensing portion; a second sheet of thermoplastic material overlying said first sheet on the open side of said troughs and heat sealed thereto to define a plurality of closed liquid filled containers; a plurality of cut out portions extending inwardly from one end of said sheets to form openings between each pair of reduced dispensing portions of said troughs, the edges of said cut out portions having protrusions thereon; means defining a rupture score line across each of said dispensing portions; a plurality of open celled foam plastic applicator members one enclosing each dispensing portion respectively, engaging with said protrusions and welded to said dispensing portions; and means defining a score line between each adjacent trough to facilitate separation into individual cleaning sticks.

Claim 3

A method of manufacturing strips of cleaning sticks for applying a volatile cleaning liquid to a surface to be cleaned, the sticks being joined together by fillets comprising a rupture separation line, the steps comprising: a. forming elongated troughs having a reduced cross section dispensing portion at one end, parallel to each other, side by side and facing in the same direction in a first sheet of thermoplastic material; b. filling said troughs with the liquid; c. fitting a second sheet on to said first sheet; d. joining said sheets by each sealing along their contacting surfaces to form a plurality of sealed liquid filled sticks; e. cutting the composite sheet between adjacent dispensing portions to form openings with protrusions on the edges thereof; f. forming rupture initiation lines across each dispensing portion and separation lines between each adjacent trough for separating sticks; g. disposing open celled plactic foam material in the form of a single piece band and of a length sufficient to extend over all sticks at that end having the dispensing portion so as to contact both said sheets and overlie said rupture initiation lines and welding said foam to said sheets parallel to said separation lines; and h. cutting said foam between adjacent dispensing portions.

Claim 4

A method of manufacturing strips of cleaning sticks for applying a volatile cleaning liquid to a surface to be cleaned, the sticks being joined together by fillets comprising a rupture separation line, the steps comprising: a. forming elongated troughs having a reduced cross section dispensing portion at one end, parallel to each other, side by side and facing in the same direction in a first sheet of thermoplastic material; b. filling said troughs with the liquid; c. fitting a second sheet on to said first sheet; d. joining said sheets by each sealing along their contacting surfaces to form a plurality of sealed liquid filled sticks; e. cutting the composite sheet between adjacent dispensing portions to form openings with protrusions on the edges thereof; f. forming rupture initiation lines across each dispensing portion and separation lines between each adjacent trough for separating sticks; g. disposing open celled plactic foam material in the form of a single piece band and of a length sufficient to extend over all sticks at that end having the dispensing portion so as to contact both said sheets and overlie said rupture initiation lines and welding said foam to said sheets parallel to said separation lines; and h. cutting said foam between adjacent dispensing portions.
