Abstract

In a paper container 10 having a hexahedral configuration which is formed by shaping paper into a box, the paper container 10 comprises a container main body 12 and a lid member 14 hingedly attached to a back side edge part of an upper end open surface 13 of the container main body 12 and adapted to open/close the upper end open surface 13, a front board 15 of the container main body 12 being formed with a concave cutout part 16 extending from the upper end open surface 13. The lid member 14 comprises an upper surface lid part 17 for covering the upper end open surface 13, a front surface lid part 18 large enough to cover the concave cutout part 16, and a pair of side lid parts 19 interposed between side edge parts of the upper surface lid part 17 and side edge parts of the front surface lid part 18 and adapted to vertically join the front surface lid part 18 with the upper surface lid part 17. A tongue-like lock part 26 is disposed beneath the concave cutout part 16 and adapted to lock a lower end part of the front surface lid part 18 of the lid member 14.

A paper container having a hexahedral configuration which is formed by shaping paper into a box, said paper container comprising:

a container main body and a lid member hingedly attached to a back side edge part of an upper end open surface of said container main body for selectively closing the upper end open surface,
an inner carton part being mounted on and separate from an inner side of said container main body and a concave cutout part being formed as a complete opening in a front board of said inner carton part said cutout part being large enough to allow removal of contents of said box from a front side, and
said lid member comprising an upper surface lid part for covering said upper end open surface, a front surface lid part large enough to cover said concave cutout part, and a pair of side lid parts interposed between side edge parts of said upper surface lid part and side edge parts of said front surface lid part and adapted to vertically join said front surface lid part with said upper surface lid part,
said container main body and lid member being formed by cutting and dividing said hexahedral paper box through a severance guide line extending from opposite ends of a connecting ridge line between an upper board and a back board of said paper box, and
said severance guide line extending obliquely downward from the opposite ends of said connecting ridge line along a pair of side boards and extending along said front board beneath said concave cutout part formed in the front board of said inner carton so that an upper half of said front board of said inner carton part is above said severance guide line;
and
said cutout part and said lid member being of a size to allow contents of said container to be removed when the upper surface lid part of said lid member extends only as far backward as said back board,
wherein said paper container is for storing a sheet-like detergent, a tablet-type detergent or an agglomerated detergent.

Detailed description7,396 words

#As shown in FIG. 1, a paper container 10 according to a first embodiment of the present invention is used, for example, as a container for containing a sheet-like detergent 11 of a thin plate-like form arranged in a multilayer. The sheet-like detergent 11 is formed into a sheet by sandwiching a washing detergent between water-soluble sheets. This sheet-like detergent 11 is thrown into a washing machine or the like as it is and used for washing.

#The paper container 10 according to the first embodiment is a rectangular parallelepiped paper container which is formed by shaping a cardboard into a box. The paper container 10 comprises a container main body 12 and a lid member 14 hingedly attached to a back side edge part of an upper end open surface 13 of the container main body 12 and adapted to open/close the upper end open surface 13. A front board 15 of the container main body 12 is formed with a concave cutout part 16 extending from the upper end open surface 13. The lid member 14 comprises an upper lid part 17 adapted to cover the upper end open surface 13, a front lid part 18 large enough to cover the concave cutout part 16, and one pair of side lid parts 19 interposed between side edge parts of the upper lid part 17 and side edge parts of the front lid part 18 and adapted to vertically join the front lid part 18 with the upper lid part 17.

#The cardboard constituting the paper container 10 is a laminated paper which comprises, for example, a paper base material, a printed layer and an outer film adapted to cover an outer surface of the paper base material, and an inner film adapted to cover an inner surface of the paper base material. This cardboard is cut into a predetermined development configuration and then folded into a three-dimensional configuration. Then, by bonding appropriate areas of the cardboard, a rectangular parallelepiped paper container 10 having, for example, a vertical length of 90 mm and a lateral length of 130 mm and a height of 100 mm.
