Cup formed container having edge flange
First Claim
1. Cup formed container made of a plain punched container blank of cardboard or similar stiff material and comprising a bottom (1), two opposite side pieces (2) which are coherent with the said bottom, and which are wider than the side of the bottom (1) with which they are connected, and two opposite joint flaps (3) which are of the same or less width than the side of the bottom (1) with which they are connected, characterized in that each side piece (2) with a central side part (5) forms a complete container side and with an outer side part (6,7) on each side of said central side part (5) forms part of an adjacent container side, so that the outer side parts (6,7) of the two side pieces (2) jointly form at least partially the intermediate container sides, whereby the joint flaps (3) serve to complete the said intermediate container sides and keep the parts thereof together, and that the container round the complete upper edge, including the corners, is formed with a downwards directed narrow edge flange, which is made of and folded from the same piece of material as the container sides and which forms an angle to the container sides, said flange being continuous and unbroken along said central side parts and said outer side parts of said side pieces, and hence around the corners of the container upper edge.

Abstract
A cup formed container made of a punched container blank of cardboard or the like has two opposite side pieces connected to the container bottom, and being wider than the bottom side with which they are connected. Opposite joint flaps are connected to the other two sides of the bottom. Each side piece has a central part which forms a complete container side and an outer side part on each end of the central part, these outer side parts each forming part of an adjacent side of the container, so that the outer side parts jointly form at least part of the intermediate container sides, with the joint flaps serving to complete the intermediate sides and keep the parts together. Around the complete upper edge of the container, including the corners, the container is formed with a downwardly directed narrow edge flange, which is made of and folded from the same material as the container sides and which forms an angle to the container sides, the flange being continuous and unbroken along the central side parts and the outer side parts of the side pieces, and hence around the corners of the container upper edge. The container may be lined. The construction stiffens the edge of the container, facilitates use of a reclosable lid, and removes the edge of the cardboard material from the contents of the container.
