A fastener-free box with fast assembly comprises a baseboard, a front board, a rear board, a left board, a right board, and a cover board. An insert-connection structure that is configured to form an insert connection with a respective adjacent board is integrally formed on each of the board; and, a connection structure configured to couple with each other is integrally and individually formed on each of the cover board and the rear board. The structure of the box is simple. In addition, an interlocking structure can be formed after the box is assembled, enabling a robust box structure. Furthermore, the box is ideal for outdoor use as it is water proof.

A basket includes an annular sidewall and an expanded mesh securely mounted onto a lower portion of the annular sidewall to define a containing space that has an upward opening. The annular sidewall includes an annular groove laterally defined in a lower portion of the annular sidewall and an annular flange inwardly extending from a lower edge of the annular sidewall, wherein a width of the annular flange is greater than a depth of the annular groove. An annular lip is outwardly formed on a top edge of the annular sidewall by folding. The expanded mesh has an annular edge received in the annular groove and is supported by the annular flange.

A container is produced from a single-layered, helically bent sheet-metal trip (20). A first, helically running peripheral portion (22) of the sheet-metal strip (20) is bent out in the direction of the outside of the container (10) to form a helically running bent out edge (24). A second, helically extending peripheral portion (26) of the sheet-metal strip (20) overlaps a third portion (28) of the sheet-metal strip (20) on the inside of the container (10). The third portion is adjacent to the bent-out edge (24) and extends in the direction of the second peripheral portion (26) from the bent out edge (24). The second peripheral portion (26) is connected in a fluid-tight manner to the third portion (28) of the sheet-metal strip (20) on the inside of the container (10).

A rigid container floor and a container with the same floor are disclosed. A plurality of blind waves (1) are provided in parallel on the rigid container floor (10), and upwards protrude out of the upper surface of the rigid container floor (10). The blind wave (1) includes a first edge and a second edge, with the length of the first edge longer than the length of the second edge. The parts between the first edges of the adjacent blind waves and the parts between the first edges of the blind waves and the first edges of the rigid container floor (10) are flat plate structures. The flat plate structures are connected to the blind waves (1) through waved connecting plates, and the parts between the second edges of the blind waves (1) and the second edges of the rigid container floor (10) are connected to the blind waves (1) through waved connecting plates. The multiple blind waves (1) provided in parallel can increase the strength and reduce the assembly deformation. And the edge structure of the rigid container floor (10) can be automatically and continuously welded with a container underframe because the edge parts of the rigid container floor (10) are connected to the blind waves through the waved connecting plates.

A bottle for holding liquids that is biodegradable and that is made from environmentally sustainable materials. The bottle includes a body, a shoulder, a neck portion, and a cap. According to one aspect, the neck portion of the bottle is made of bioplastic, and the shoulder and body of the bottle are made from thermoformed pulp. The bioplastic neck can mate with, and be adhered to, the shoulder, and the shoulder can mate with, and be adhered to, the pulp body.

A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.
