Total Claims: 7
Claim 1
Independent Claim
226 words
In a carton having a plurality of carton walls arranged to define a container body, the improvement wherein: one of the carton walls is formed of first and second end wall panels joined together along an axial fold line, which extends the length of the panel, the wall panels being positioned to form an infolded V-shaped carton wall; and a transverse fold line extends across the axial fold line and across the first and second end wall panels so that a section of eaCh panel may be hinged from their infolded position to a second position in which they extend beyond adjoining carton walls to form a pour spout; and pull tab means attached to the first and second end wall panels, formed by 1. a glue flap hinged to the first end wall panel and extending the full length thereof, and a weakened line formed obliquely across the glue flap to divide it into first and second sections, and being in registry with a portion of the transverse fold line, 2. an extension flap hinged to the second end end wall panel and having the same shape as the first section of the glue flap; the glue flap and the extension flap being positioned along said axial fold line and adapted to provide handle means for movement of the pour spout to its second position.
