Disclosed is a corrugated paperboard box making machine which comprises a sheet feeding apparatus, a processing apparatus, a folder-gluer, a counter-ejector for stacking the box-structured corrugated paperboard sheets and separating them as a batch, a speed setting unit for setting a sheet feeding speed, and a control apparatus. The control apparatus is operable to execute a sheet feeding control processing of the sheet feeding apparatus such that a sheet feeding operation of feeding one corrugated paperboard sheet is successively repeated a number of times corresponding to the number of the given number of box-structured corrugated paperboard sheets in the batch, and a sheet feeding stop control processing of, when the sheet feeding speed is greater than an allowable speed, the sheet feeding apparatus such that the sheet feeding operation is stopped at least once after execution of the sheet feeding control processing.

A manufacturing method of printed corrugated cardboard comprising the steps of: a) providing a paper liner board (23) with an ink receiving layer; and b) inkjet printing an image with one or more pigmented aqueous inkjet inks on the ink receiving layer using piezoelectric through-flow print heads (25) having nozzles with an outer nozzle surface NS smaller than 500 μm2; wherein the one or more pigmented aqueous inkjet inks contain water in an amount of A wt % defined by: wherein the wt % is based on the total weight of the aqueous inkjet ink; wherein sqrt(NS) represents the square root of the outer nozzle surface area NS; and wherein A wt %≥40 wt %.

A box suitable for the packaging of a consumer product is formed by helically wrapping an elongated continuous strip of material around a mandrel to form a main body with a plurality of bands. In one embodiment, adjacent bands partially overlie one another to form a multi-paneled main body with an open top end and an open bottom end. An adhesive is disposed within the region of contact between adjacent bands to retain the shape of the main body. First and second sets of slots are formed in the main body to create flaps dimensioned to selectively enclose the open top and bottom ends, respectively. To define the flaps and promote pivotal articulation, the main body is also preferably provided with score lines. By adjusting the configuration of the mandrel, a customized box can be constructed that is sized to receive a consumer product with limited wasted space.

Disclosed is a corrugated paperboard printer comprising a pressing device for applying a pressing force to press a chamber which reserves ink toward an anilox roll. The pressing device is configured to apply a first pressing force, and a second pressing force which is greater than the first pressing force, respectively, to a first pressing area and a second pressing area in a back surface of a chamber frame. In a state in which no pressing force is applied by the pressing device, bending occurring in the chamber frame due to a load transmitted from a printing roll to the chamber frame via the anilox roll as printing is performed to a corrugated paperboard sheet is greater in the second pressing area than in the first pressing area.

A slitter device includes an upper rotary shaft and a lower rotary shaft that are supported so as to be able to rotate. An upper slitter head that is supported by the upper rotary shaft so as to be able to rotate therewith. A lower slitter head that is supported by the lower rotary shaft so as to be able to rotate therewith and that is disposed on one side of the upper slitter head in the axial direction of the lower rotary shaft. An upper movement device that can move the upper slitter head in the axial direction of the upper rotary shaft. A lower movement device can move the lower slitter head in the axial direction of the lower rotary shaft. A control device that controls movement of the upper movement device and the lower movement device.

The present paper cup comprises a cup body, and the cup body comprises inner paper and outer paper. There are hollow bulges on the outer paper, and the outer paper forms a connecting part. The inner side of the connecting part bonds to the outer side of the inner paper, and the cup rim of the outer paper extends to the cup rim of the inner paper. In addition, the outer side of the cup rim of the inner paper bonds to the inner side of the outer paper, and both cup rims of the outer paper and the inner paper bend outward to form a double layered crimping. The manufacturing process for the present paper cup includes: paper preparation, rolling, composition, sheet cutting, forming, molding and etc.

A corrugated paperboard box is provided in which when flaps are bent, a perforated line along which the flaps can be separated from the box is less likely to break. Such a corrugated paperboard box includes a peripheral wall and top flaps, and is formed, at the boundary area between the peripheral wall and the top flaps, with a groove-shaped reverse scoreline recessed on the side of an outer linerboard, and a pair of groove-shaped recesses recessed on the side of an inner linerboard, and extending in parallel to each other so as to sandwich the area in which the reverse scoreline extends. The corrugated paperboard box is further formed, in one of the groove-shaped recesses, with a perforated line along which the top flaps can be separated from the peripheral wall. The top flaps can be bent along the perforated line toward the inner surface of the peripheral wall.

A locking device for a box includes a first panel defining a locking tab separable from the first panel and comprising a first tab subpanel and a second tab subpanel; the first tab subpanel extending from the first panel and the second tab subpanel extending from the first tab subpanel, the second tab subpanel including a neck and an ear, the ear extending from the neck in a lateral direction of the locking tab; and a second panel defining a locking opening, the locking opening sized to receive and capture the locking tab, the locking tab configured to engage an edge of the locking opening and thereby configured to prevent movement of the locking tab with respect to the locking opening in an opening direction of the locking device.

A bag for receiving refuse may comprise a bag body, the bag body including an inside surface, an outside surface, and a rim defining a mouth. The bag may further comprise a first strip of material disposed on the inside surface of the bag body proximate the rim.
