A packaging box, cutouts, method and device for producing corrugated cardboard boxes comprising walls, a base (6) and a cover (7), the inner face of the base being provided with at least two recesses (33) and the cover comprising at least two tabs (38) adhered to the upper face thereof, directly above the recesses of complementary shape. The recesses and/or the tabs are situated fully inside the corresponding face or faces (31, 32).

An overwrap container includes a base container having a first side seam on a side wall that extends along a longitudinal axis to define an internal volume, and a bottom connected to the side wall. An overwrap is positioned over the side wall of the base container and has a second side seam aligned longitudinally with the first side seam. Connecting elements are positioned between the side wall of the base container and the overwrap, and join the side wall of the base container and the overwrap together except in an area along the aligned first and second seams to define an uniform spacing extending continuously between the side wall and the overwrap forming an air gap there between.

A gluing device for automatically gluing and folding a gluable item. The gluing device includes a support structure upon which a gluing apparatus and a support plate assembly are mounted. The support plate is configured for supporting and aligning a gluable item for gluing and assembly by the gluing apparatus. The gluing apparatus includes a first clamp configured for selectively and securely holding a first portion of the gluable item on the support plate, a glue dispensing nozzle fluidly coupled to a glue supply, and a folding apparatus configured for folding the first portion of the gluable item onto a second portion of the gluable item after glue has been applied. A method for automatically gluing and folding a gluable item is also disclosed.

An improved mailer folding apparatus that forms mailers from mailer blanks. The mailer folding apparatus comprises a transport assembly and one or more folding assemblies. The transport assembly moves mailer blanks and/or mailers through the mailer folding apparatus. The one or more folding assemblies may each comprise a folding system and a carriage system. The folding system may selectively allow for the folding of a mailer blank into a mailer. A carriage of the carriage system may move the folding system longitudinally between different positions relative to the transport assembly. An engagement system separate from the carriage system or integrated into the carriage system may engage and disengage the folding system with the transport system for selectively feeding a mailer blank through the folding system, or disengage the folding system for allowing a mailer blank or folded mailer to bypass the folding system.

An overwrap container includes a base container having a first side seam on a side wall that extends along a longitudinal axis to define an internal volume, and a bottom connected to the side wall. An overwrap is positioned over the side wall of the base container and has a second side seam aligned longitudinally with the first side seam. Connecting elements are positioned between the side wall of the base container and the overwrap, and join the side wall of the base container and the overwrap together except in an area along the aligned first and second seams to define an uniform spacing extending continuously between the side wall and the overwrap forming an air gap there between.

The recesses and/or the tabs are situated fully inside the corresponding face or faces (31, 32).

A system, apparatus, process, or machine for forming a container for containing a cold fluid. The container includes a sidewall construct that includes an inner sidewall extending at least partially around an interior of the container, an outer sleeve attached to the inner sidewall, and a cavity defined between the inner sidewall and the outer sleeve. The container also includes a closed bottom defining a bottom of the interior of the container, and insulating features that include the cavity and a plurality of annular bands, each annular band of the plurality of annular bands includes a spacer that extends in the cavity from the inner sidewall to the outer sleeve. Adjacent bands define a respective pocket of a plurality of pockets in the cavity such that the insulating features maintain a desired temperature of the cold fluid.

Disclosed are a container for containing a cold or hot fluid and methods of forming said container. The container includes a sidewall construct including an inner sidewall extending at least partially around an interior of the container, an outer sleeve attached to the inner sidewall, and an air gap defined between the inner sidewall and outer sleeve. The width of the air gap is defined by a plurality of adhesive layers applied as successive annular beads to the inner sidewall. Methods can be employed to maximize the bead height of at least one of the adhesive layers to form the desired width of the air gap while maintaining adhesion properties and minimizing the amount of adhesive material used. Bead height for each layer can be optimized by controlling the type of adhesive material used, the application rate and temperature, the application angle, the cooling rate, and the dwell time.
