Abstract
Abstract of the Disclosure A document file having a pair of covers and a plurality of bag members put one upon another and sealed together and to the cover at all edges except the top edge. Each cover has an auxiliary sheet hot-sealed to one side of the cover at three edges. The auxiliary sheet has a wide gusset to form a large pocket between the cover and the auxiliary sheet. Alternatively, the padding enclosed in the cover has a smaller width than the width of the cover to form a large pocket between the cover and the auxiliary sheet.
Description
1 3~0670 DOCUMENT FILE
BACKGROUND OF THE INVENTION
The present invention relates to a document file. A document file is known which comprises a pair oE covers and a plurality of bag members of synthetic resin sheets put one upon another and hot-sealed to the covers and to one another (Japanese Unexamined Utility Model Publication No. 61-175481). Co-pending Canadian Patent Application Serial No. 549,935 discloses a related invention.
Each cover has an auxiliary sheet having its one surface hot-sealed to the cover at three sides to form a pocket. The ones at both ends of the laminated bag members have their surfaces facing the respective covers hot-sealed to the auxiliary sheet at three sides.
The auxiliary sheet between the bag member and the cover at each end of the file define a pocket which is so small as to accommodate only a small number of paper sheets.
SUMMARY OF THE INVENTION
According to one aspect of the present invention there is provided a document file in which the cover and the auxiliary sheet define a pocket having substantially the same capacity as each bag member at least at one end of the file.
In accordance with a further aspect of the present invention, there is provided a document file comprising a plurality of ~ -1- ~
upwardly opening compartment members each having a compartment therein, each one of said plurality of upwardly opening compartment members having top, bottom, left, and right edges, and said plurality of upwardly opening compartment members being attached together in accordion-like fashion; a pair of auxiliary sheets, each one of said pair of auxiliary sheets having top, bottom, left, and right edges, and each one of said pair of auxiliary sheets being attached to an outermost one of said plurality of upwardly opening compartment members for partially defining an outermost pocket; a pair of covers, each one of said pair of covers being attached to an outermost surface of one of said pair of auxiliary sheets, and each one of said pair of covers having top, bottom, left, and right edges; each cover comprising a pair of cover sheets and fabricated of synthetic resin and joined together along the edges thereof, and a padding between said cover sheets, each said padding having top, bottom, left, and right edges, the distance between the left and right edges of said padding being substantially less then the distance between the left and right edges of said cover for defining padding-free portions at the left and right sides of said covers, each said bottom edge, left, and right padding-free portions of each said cover being attached to said bottom, left, and right edges of one of said pair of auxiliary sheets for partially defining an outermost pocket, each said cover and said auxiliary sheet jointly defining said outermost pocket, and each said outermost pocket being as large as the compartment of each one of said plurality of upwardly opening compartment members.

Fig. 3 is a vertical sectional view of the bag member showing the portions at which the adjoining bag members are hot-sealed together; and Fig. 4 is a sectional view of the same showing how the auxiliary sheet is sealed to the cover.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIUENT
In the drawings, a pair of covers are represented by numerals 1a and lb. A plurality of bag members 2 are disposed between the covers.
The covers 1a and 1 7D each comprise synthetic resin sheets 4 and a padding 3 enclosed in the sheets. The bag members 2 are each made of two soft synthetic resin sheets 5 hot-sealed together by high frequency sealing at their lower edge and both side edges to form a bag member.
An auxiliary sheet 6a (6b) is hot-sealed to the back side of each cover at three sides to form a pocket 7. The bag members 2 are put one upon another. The ones at both ends of the row are hot sealed to the auxiliary sheets 6a and 6b. Each of the auxiliary sheets 6a and ~b should be formed at both sides with gussets having _ 3 ~
a larger width than the gussets o~ the bag members 2.
Owing to the wide gussets, the auxiliary sheet and the cover at each end of the file can form a pocket 7 substan-tially as large as the pocket of each bag member 2 in capacity. In order to prevent the wide gussets of the auxiliary sheets from protruding from the sides of the file, the auxiliary sheets may have their side edges hot-sealed not to the extreme end of the side e~ges of the covers but to areas somewhat inside of both side edges.
Alternatively, as shown in the drawings, the cover 1b may have its padding 3 somewhat shorter than the width of the cover to form padding free portions 8 along both side edges. The limpness of the padding-free portlons wilI serve to provide a large-capacity pocket 7. The same paddiny-free portions 8 may be formed at both side edges of the cover 1a to form such large-capacity pockets at both ends of the file.
Fig. 3 shows one example of the portlons 9 of the bag member 2 at which it is hot-sealed to the adjoining ones or to the auxiliary sheets 6a or 6b.
As shown in Figs. 1 and 2, a padding 10 is disposed between every opposed pair of sealing surfaces on the adjoining bag members 2 to eliminate the limpness of the verges of the bag members. Fasteners 11a and 11b serve to close a f lap 12 0 :

DETAILED DESCRIPTION OF THE PREFERRED EMBODIUENT
In the drawings, a pair of covers are represented by numerals 1a and lb. A plurality of bag members 2 are disposed between the covers.
The covers 1a and 1 7D each comprise synthetic resin sheets 4 and a padding 3 enclosed in the sheets. The bag members 2 are each made of two soft synthetic resin sheets 5 hot-sealed together by high frequency sealing at their lower edge and both side edges to form a bag member.
An auxiliary sheet 6a (6b) is hot-sealed to the back side of each cover at three sides to form a pocket 7. The bag members 2 are put one upon another. The ones at both ends of the row are hot sealed to the auxiliary sheets 6a and 6b. Each of the auxiliary sheets 6a and ~b should be formed at both sides with gussets having _ 3 ~
a larger width than the gussets o~ the bag members 2.
Owing to the wide gussets, the auxiliary sheet and the cover at each end of the file can form a pocket 7 substan-tially as large as the pocket of each bag member 2 in capacity. In order to prevent the wide gussets of the auxiliary sheets from protruding from the sides of the file, the auxiliary sheets may have their side edges hot-sealed not to the extreme end of the side e~ges of the covers but to areas somewhat inside of both side edges.
Alternatively, as shown in the drawings, the cover 1b may have its padding 3 somewhat shorter than the width of the cover to form padding free portions 8 along both side edges. The limpness of the padding-free portlons wilI serve to provide a large-capacity pocket 7. The same paddiny-free portions 8 may be formed at both side edges of the cover 1a to form such large-capacity pockets at both ends of the file.
Fig. 3 shows one example of the portlons 9 of the bag member 2 at which it is hot-sealed to the adjoining ones or to the auxiliary sheets 6a or 6b.
As shown in Figs. 1 and 2, a padding 10 is disposed between every opposed pair of sealing surfaces on the adjoining bag members 2 to eliminate the limpness of the verges of the bag members. Fasteners 11a and 11b serve to close a f lap 12 0 :
