Abstract
Manufacturing method to make simultaneously two paper containers having a front surface and a rear surface, opposed at their support base by three superimposed strips of paper, the intermediate strip being shaped like a sheath sandwiched between the other two strips on which longitudinal folds are formed which, after the containers are separated, serve as a reinforcement of their support base. The invention also includes the device for implementing the method, as well as the containers thus obtained.
Claims21
A method for manufacturing at least two containers simultaneously, each container including a first side portion, a second side portion, and a bottom folded portion, the method comprising:
- applying a substantially rectangular coating of glue to an intermediate strip at substantially regularly spaced intervals, the intermediate strip having a first edge and a second edge;
- folding the intermediate strip so that each of the first edge and the second edge covers some portion of the rectangular coating;
- feeding each of a lower strip and an upper strip along a first direction;
- feeding the folded intermediate strip in the first direction so that the intermediate strip is disposed between the lower strip and the upper strip;
- assembling the upper strip, the intermediate strip, and the lower strip to make a layered structure;
- and
- separating the at least two containers from the layered structure,
- wherein the first side portion of each container comprises some portion of the upper strip, the second side portion of each container comprises some portion of the lower strip, and the bottom folded portion of each container comprises some portion of the intermediate strip.
An apparatus for manufacturing at least two containers simultaneously, each container including a first side portion, a second side portion, and a bottom folded portion, the apparatus comprising:
- a device for applying a substantially rectangular coating of glue to an intermediate strip at substantially regularly spaced intervals, the intermediate strip having a first edge and a second edge;
- a device for folding the intermediate strip so that each of the first edge and the second edge covers some portion of the rectangular coating;
- a device for feeding each of a lower strip and an tipper strip along a first direction;
- a device for feeding the folded intermediate strip in the first direction so that the intermediate strip is disposed between the lower strip and the upper strip;
- a device for assembling the upper strip, the intermediate strip, and the lower strip to make a layered structure;
- and
- a device for separating the at least two containers from the layered structure,
- wherein the first side portion of each container comprises some portion of the upper strip, the second side portion of each container comprises some portion of the lower strip, and the bottom folded portion of each container comprises some portion of the intermediate strip.
