Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to container technology and more particularly, to a container formed by folding.

2. Description of the Related Art

Due to the rapid development of the times, the fast-food industry and out-eaters have developed rapidly. Also, because people want to eat at home easily, they buy disposable bowls and containers for holding foods. Many foods must be placed on a plate for convenience in terms of sight and access. However, it is very inconvenient to pour the food out the container into a dish.
It is a daily practice to make a three-dimensional container by folding the corners of a sheet material. However, the folded parts must be bonded to enhance the the strength of the container. Taiwan Patent Utility Number M255233 discloses a multi-sided paper bowl structure that is formed by folding a circular paperboard (10) into shape. The circular paperboard (10) comprises a circular base portion (11) at the center, an outer polygon (12) disposed outside the circular based portion (11), a plurality of folding lines (13) respectively outwardly extended from respective angles of the outer polygon (12) and defining a plurality of isometrically arranged pressing panels (14) and bonding panels (15). Each pressing panel (14) extends outwardly with a protruding edge (16), and a crease line (17) is formed between the protruding edge (16) and the pressing panel (14). By means of the folding lines (13), the bonding panels (15) are folded up and respectively attached to respective back sides of the respective pressing panels (14) so that the pressing panels (14) and the respective protruding edges (16) are overlapped and respectively bonded together to create a multi-sided paper bowl. However, such containers must be fixedly secured in shape by bonding. After bonding, they cannot be unfolded into a flat shape for application.
Further, US-9,045,246 B2 , entitled "Container usable as a deep bottom and shallow bottom type container, and manufacturing method thereof". This design of container is usable as a deep bottom- and shallow bottom-type container by changing between deep bottom- and shallow bottom-type container configurations by folding along prescribed ruled lines, forming a protruding part on the circumferential wall surface and forming undistorted smooth surfaces. This container is usable as a deep bottom- and shallow bottom-type container in which a deep bottom-type container configuration can be changed into a shallow bottom-type container configuration, wherein the deep-bottom type container is obtained by folding, along prescribed ruled lines, a single blank having a part with prescribed ruled lines and corresponding to the bottom surface (referenced by 12D), a part sectioned into compact triangles and quadrilaterals and corresponding to a partition surface, and a part corresponding to an inner folded surface (referenced by 4), and the deep-bottom type container comprises a protruding part formed without distortion on the circumferential wall surface. According to this design, the deep-bottom type container is obtained by folding, and the deep bottom-type container configuration can be changed into a shallow bottom-type container configuration. After folded into shape, the deep bottom-type container configuration does not provide any reinforced parts to prevent the contained foods from being spilled out of the container. Therefore, when the food is contained in the container, the support force around the container is completely insufficient, and there is still inconvenience in application.
