Abstract
Abstract A composite packing container comprising an inner container (1) which comprises a frame member (2) having an opening (3) and an inner circumferential edge (4) projecting downwards therefrom, a closure member (5) detachably mounted in the opening (3) for closing the same, and a synthetic resin film made bag (6) which is, at its bottom surface portion (8), attached to the whole circumference of the lower end portion of the inner circumferential edge (4) of the frame member (2), with its top opening portion being remained open downwards and a paper board made outer container (13) which comprises a side barrel (9) arranged to receive the foregoing bag (6), a pair of opposite inner flaps (10, 10) connected to an upper open peripheral edge of the side barrel (9) and arranged to be inserted into a cap formed between the frame member (2) and the bottom surface portion (8) for supporting the frame member (2) from below, a pair of opposite outer flaps (11, 11) arranged to cover the frame member (2).

A composite packing container comprising an inner container (1) which comprises a frame member (2) having an opening (3) and an inner circumferential edge (4) projecting downwards therefrom a closure member (5) detachably mounted in the opening (3) for closing the same, and a synthetic resin film made bag (6) which is, at its bottom surface portion (8), attached to the whole circumference of the lower end portion of the inner circumferential edge (4) of the frame member (2), with its top opening portion being remained open downwards;and a paper board made outer container (13) which comprises a side barrel (9) arranged to receive the foregoing bag (6), a pair of opposite inner flaps (1 0 , 1 0 ) connected to an upper open peripheral edge of the side barrel (9) and arranged to be inserted into a gap formed between the frame member (2) and the bottom surface portion (8) for supporting the frame member (2) from below, a pair of opposite outer flaps (11, 11) arranged to cover the frame member (2) closed by the closure member (5) and brought in engagement with the inner flaps (1 0 , 1 0 ) and perforated lines (12, 12) so cut in such regions of the outer flaps (11, 11) as to conform to the shape of the closure member (5)that come to face the closure member (5) at the time of shutting up the outer flaps (11, 11), and the inner flaps (1 0 , 1 0 ) and the outer flaps (11, 11) are adhered together at their mutually facing inner surfaces.
Claim 2
Dependent Claim
265 words
A composite packing container comprising an inner container (1) which comprises a frame member (2) having an opening (3) and an inner circumferential edge (4) projecting downwards therefrom a closure member (5) detachably mounted in the opening (3) for closing the same, and a synthetic resin film made bag (6) which is, at its bottom surface portion (8), attached to the whole circumference of the lower end portion of the inner circumferential edge (4) of the frame member (2), with its top opening portion being remained open downwards;and a paper board made outer container (13) which comprises a side barrel (9) arranged to receive the foregoing bag (6), a pair of opposite inner flaps (1 0 , 1 0 ) connected to an upper open peripheral edge of the side barrel (9) and arranged to be inserted into a gap formed between the frame member (2) and the bottom surface portion (8) for supporting the frame member (2) from below, a pair of opposite outer flaps (11, 11) arranged to cover the frame member (2) closed by the closure member (5) and brought in engagement with the inner flaps (1 0 , 1 0 ) and perforated lines (12, 12) so cut in such regions of the outer flaps (11, 11) as to conform to the shape of the closure member (5)that come to face the closure member (5) at the time of shutting up the outer flaps (11, 11), and the inner flaps (1 0 , 1 0 ) and the outer flaps (11, 11) are adhered together at their mutually facing inner surfaces.
Claim 3
Dependent Claim
59 words
A composite packing container as claimed in claim 1, wherein the bottom surface portion (8) of the foregoing bag (6) is adhered to the whole circumference of the lower end portion of the inner circumferential edge (4) of the opening (3) of the frame member (2) so as to tightly close the opening (3) of the frame member (2).
Claim 4
Dependent Claim
121 words
A container as claimed in claim 1, wherein the inner container (1) is provided with a step portion (4a) formed on the periphery of the outer surface of the inner circumferential edge (4) surrounding the opening (3) of the frame member (2)and an engageably fastening ring (7) arranged to be detachably mounted on the step portion (4a),and the bottom surface portion (8) of the bag (6) placed along on the lower end of the inner circumferential edge (4) of the frame member (2) is firmly held, by means of mounting the fastening ring (7) on the step portion (4a), between the ring (7) and the step portion (4a) so as to tightly close the opening (3) of the frame member (2).
Claim 5
Dependent Claim
38 words
A container as claimed in claim 1, wherein the frame member (2) and the closure member (5) are made of synthetic resin, and beads (14) are formed concentrically on the central plate area of the closure member (5).
Claim 6
Dependent Claim
23 words
A container as claimed claim 1, wherein the bag (6) has the bottom surface portion (8) which is an expanded flat surface one.
Claim 7
Dependent Claim
198 words
A container as claimed in claim 1, wherein the outer container (13) is rectangular in form and the bag (6) so formed that a middle surface bottom portion (63) of a ]- shape folded sheet is folded inwards at its center transversal fold (15, Fig. 5A), and the resultant right and left parts (63a, 63a) of the folded middle surface portion (63) and such parts (62a, 62a) of the two side surface portions (62, 62) that overlap the right and left side parts (63a, 63a) thereof are fused together in the form of V in both end regions of the middle surface bottom portion (63, Fig. 5B) and the parts (63a, 63a) of the middle surface bottom portion (63) are turned inwards about the fold (15) to put together and the respective opposite side edges (62a, 62a; 62a, 62a) of the opposite side surface portions (62, 62) as well as both side edges(63b, 63b) of the middle surface bottom portion (63) are fused together to form the two sealed side edges (16, 16) of the bag (6, Fig. 5C)and the bag (6) is expanded to form a square bottom surface portion (8) of the bag (6, Fig. 4).
