Abstract
A method is disclosed for constructing a flexible container (10) with a tubular fitment (13). The method includes placing the fitment upon a mandrel (22), positioning the mandrel supported fitment between the unsealed sides (25, 26) of the container, sealing the top edge (28) of the sides about a base portion (18) of the fitment and fully withdrawing the mandrel from the fitment and from between the sides so that the side edges (29) and top edge of the sides may be sealed to form a completed container.
Claims4
A method of constructing a container made from a sheet of flexible material with a fitment of the type having a relatively wide tubular base from which a relatively narrow tubular neck extends, and with the method comprising the steps of
- (a) forming the sheet into a generally U-shape having a bottom from which two sides extend that have sealable side edges and a sealable top edge,
- (b) placing the fitment upon a mandrel,
- (c) positioning the fitment base supported on the mandrel between the top edges of the sides,
- (d) sealing the top edges to the fitment base,
- (e) removing the mandrel from the fitment base by moving it towards the sheet bottom and then from between the sides, and
- (f) sealing the sheet along the side edges and top edges, thereby constructing the container.
A method of constructing a container made from a sheet of flexible material with a fitment of the type having a relatively wide tubular base from which a relatively narrow tubular neck extends, and with the method comprising the steps of:
- (a) forming the sheet so as to have a bottom from which two, overlaying container sides extend that have sealable side edges and a sealing top edge,
- (b) placing a fitment upon a mandrel;
- (c) extending one container side over the mandrel supported fitment while simultaneously extending the other container side over the opposite side of the mandrel supported fitment;
- (d) sealing the top edges of the container sides about the mandrel supported fitment;
- (e) removing the mandrel from the fitment base by moving it towards the bottom and from between the container sides;
- and
- (f) sealing the side edges and top edge of the overlaying container sides to complete the construction of the container.
