A fully compostable container is provided having an enclosed body with an opening through an interior surface and an exterior surface. The enclosed body having a plant fiber structural layer configured to biodegrade in ambient conditions into nontoxic residue and a fluid barrier layer formed on a first side of the structural layer to form the interior surface of the enclosed body, the fluid barrier layer configured to biodegrade in ambient conditions into nontoxic residue. The container is gradually biodegradable when exposed to a set of factors in a natural environment and has a shelf life of six months when stored under standard commercial conditions.

Provided is a paper container including four body portion panels (4, 5, 6, 7) forming a cylindrical body portion having a square section, the paper container being configured so that upper ends of the body portion panels are continuously provided with a pair of gable roof-forming panels (13, 14), which include exterior top seal panels (17, 18) and are opposed to each other, and provided with a pair of gable wall-forming panels (21, 22), which include interior top seal panels (25, 26) and are opposed to each other, and any one of which serves as a spout and is to be opened, the gable wall-forming panels (21, 22) are folded out between the gable roof-forming panels (13, 14), and the exterior top seal panels (17, 18) and the interior top seal panels (25, 26) are heated and sealed with each other at a predetermined position so as to be hermetically sealed, in which: a seal width on a non-opening side (B) of a top seal portion (30), which is formed by heating and sealing the exterior top seal panels (17, 18) and the interior top seal panels (25, 26) with each other at the predetermined position, is larger than a seal width on an opening side (A) serving as the spout, the seal width being downwardly enlarged from the opening side (A) to the non-opening side (B); and top-portion lateral-fold-lines (11, 12) serving as boundaries between the gable roof-forming panels (13, 14) and the body portion panels (4, 6) are downwardly tilted from the opening side (A) to the non-opening side (B). With this configuration, it is possible to provide a paper container including a top seal portion easy to be grasped without deteriorating capability of opening with ease of the top seal portion.

A package (10) having a corner indent wall (12) includes a plurality of upstanding side walls including a first side wall (14), a front wall (16), a rear wall (20), a second side wall (18) and an indent wall (36). The first side wall is contiguous with the front wall, the front wall is contiguous with the indent wall which is contiguous with the second side wall/ the second side wall is contiguous with the rear wall and the rear wall is sealed to the first side wall. The package includes a sealed bottom wall (22) formed from a plurality of bottom wall panels, each bottom wall panel adjacent a corresponding side wall. The package includes a gable top (24) formed from a plurality of gable panels (26,28,30,32) contiguous with their adjacent gable panels and their respective side walls and separated from their respective side walls by an upper crease line (64). The upper crease line is straight as separating two of the gable panels from their respective side walls and is curved downwardly as separating two of the gable panels from their respective side walls. The carton can be formed symmetrical and asymmetrical. A blank (50,150) for the carton is disclosed.

A container (1)for food products is fashioned in such a way that there are no interstitial spaces or stagnation traps on the inside. The bottom end (8) of the container is fashioned by bending and flattening one end portion (7) of a tubular blank in such a way as to produce two triangular stiffening folds (10) of double thickness, each penetrable along one open side coinciding with the base (l0a) of the triangle; before the folds (10) are turned inward, the open sides are sealed by bonding the two triangular thicknesses together along the base (10a) so that the folds remain isolated from the inside of the container (1).
摘要:
A process for forming a container blank with flexible fold lines from polylactic acid sheet material. In the process, a sheet of polylactic acid material suitable for use as a container blank is placed between a forming tool and a substantially flat surface. The temperature of the forming tool is maintained at a point between the softening temperature and the melting temperature of the polylactic acid sheet. Then, a high frequency electric field is created between the forming tool and the flat surface so as to heat a portion of the polylactic acid sheet sandwiched therebetween, while pressing the forming tool into the sheet to a depth of at least 25% of the thickness of the sheet and forming bulges in the sheet adjacent to opposite sides of the tool. Next, the polylactic acid sheet is allowed to cool while maintaining the same in a substantially flat condition.
摘要:
A paper container is provided that allows the content to be checked, prevents the content from deteriorating for a long period of time, and is excellent in, for example, storage and preservation properties. Furthermore, a paper container is provided that can be subjected to a retort sterilization process, prevents the content from deteriorating for a long period of time, and is excellent in, for example, storage and preservation properties. A paper container formed of a laminate including at least a paper layer is provided. The paper layer has a cutout part that is covered with a gas barrier laminate. The gas barrier layer of the gas barrier laminate is formed of a composition containing a neutralized product of a polymer containing at least one functional group selected from a carboxyl group and a carboxylic anhydride group, and a hydrolysis condensation product of at least one compound (L) containing a metal atom to which at least one characteristic group selected from a halogen atom and an alkoxy group has been bonded. The -COO-groups contained in the at least one functional group are neutralized at least partly with a metal ion having a valence of two or more.

According to the practice of this invention, the noted unwanted adhesion between the second panel (14) and the first panel (12) attendant the formation of the sideseam joint is eliminated by providing the second panel with a cutout. That portion which is cut out corresponds in form to the triangular cutout or truncated portion at the tapered end (28) of the sideseam forming fifth panel (20). In this way, when compression of the first panel against the sideseam panel and the first panel occurs, there is no hot and sticky exposed area of the first panel which will adhere to the second panel.
