3~7 SACK OR BAG WITH A BOTTOM BEING RECTANGULAR IN THE FILLED
STATE AND A HANDLE PORTION GLUED THERETO
BACKGROUND OF THE INVENTION
Field of the Invention This invention relates to a sack or bag with a bottom be-ing rectangular in the filled state, the bottom being formed by side tucks partially overlapping corner tucks, and with a handle portion glued or welded thereto and consis-ting of a middle web section with the griphole and lateral leg-like strips of fle~i-ble material being connected therewith.
Description of Prior Art Sacks or bags of this kind are for instance known from the German Utility Models 81 15 909 and 82 07 889. Said known sacks or bags, however, show the drawback that the leg-like strips forming a bottom leaf, so to speak, which in their middle region are connected with ~he web section being provided with the griphole, are glued with the bottom all-over or nearly all-over, so that through the web section, i.e. in the region of the longitudinal center plane running through the bot-tom of the sack, considerable strains are exercised on the bo~tom during carrying, said strains resulting from the fact that the forces exercised by the web section are introduced therein substantial ly in the region of a line centrically extending through the bot-tom square.
Summary of the Invention It is an object of the invention to provide a sack or bag o the kind mentioned hereinbefore, in which the bottom itself is relieved to a large degree of the carrying forces which are introduced through ~he web section having the griphole.
37~
This problem is solved according to the invention for a sack or bag of the generic type by the fact that the bottom moun-ted thereon is conventionally glued or welded to a leaf connect-ed sealingly with the inner ed~es of the corner tucks and at least with the inner edges of the side tucks adjacent to their fold lines, that the handle portion is inserted in the still open bottom, and that the leg-like strips thereof are at least partially covered by the side tucks and glued or welded thereto.
In the sack or bag according to the inven~ion, the side of the lateral leg-li~e strips of the handle portion ~acing the leaf constituted by e.g. a piece of paper or foil, wherein said strips carry in the center thereof the web section having the griphole, is not glued to said leaf, but the side tucks overlap the lateral leg-like strips and are glued or welded thereto at the sides thereof at which also the middle web section with -the griphole is located. The sack or bag according to the invention, therefore, is characterized by a tunnel which is formed between the lower side of the handle portion and the outer side of the leaf. Due to this structure, through the middle web section and the leg-like strips connected therewith, the carrying forces are substantially directly introduced into the side walls of the filled sack, so that ~he handle portion can accept considerably greater carrying forces without the sack being damaged thereby or bottom parts being strippsd thereoff.
- Advantageously, the corner tucks are formed a~ least along a portion of their width by parallel slits in the flat tube piece which constitutes the workpiece for the production of the sack nr bag.
~,~
According to a fur~her aspect of the invention it is pro-vided that one side tuck is shorther than another so that corre-sponding holding strips are obtained for sack workpieces severed 3'~7 from a tubular web at opening edges opposite to the ~ottoms.
According to another aspect of the present invention it is provided that the handle portion consists of a cu-t being fold-ed on itself, from the middle part thereof, which forms the web section, the leg-liks strips are separated by fold lines.
The leg-like strips can at least be backfolded on them-selves along a part of their length. The parts can also be back-folded on themselves to such an extPnt that they overlap each other.
Moreover, to the lower side of the leg-like strips of the handle portion an enforcement leaf can be attached which at least part-ially covers both.
Embodiments of the invention will now be described in the follow-ing with reference to the drawings.

Detailled Description of Prsferred Embodiments Fig. 1 shows a tube portion 1 severed from a tubular web of paper or thermoplastic synthe~ic resin and constituting the basic workpiece for the production of the sack. At its upper edge, the tube portion 1 is provided with two slits 2 being in parallel to each other and with respect to the lateral fold edges, the slits 2 having nearly the same distance to the later-al fold edges 3. Whila the cutting edge is aligned between the lateral slits 2 of the upper wall wi~h the lateral parts, the lower cutting edge 4 is displaced by the amount a to the inside between the lateral slits 2 so that a corresponding edge strip is obtained at the opposite lowar side wall of the sack work~
piece.
Fig. 2 shows the sack workpiece according to Fig. 1 with a bottom conventionally mounted thereon. By the mounting the cor-ner tucks 5 and tha side tucks 6, 7 are obtained, the side tuck 6 being smaller by the width of the edge strip 8 than the side tuck 7. The side tucks 6, 7 are partially separated from the cor-ner tucks 5 by the cutting lines 2. In the later closing of the bottom, the side tucks 6, 7 are folded at the pregrooved lines 9, 10.

BACKGROUND OF THE INVENTION
Field of the Invention This invention relates to a sack or bag with a bottom be-ing rectangular in the filled state, the bottom being formed by side tucks partially overlapping corner tucks, and with a handle portion glued or welded thereto and consis-ting of a middle web section with the griphole and lateral leg-like strips of fle~i-ble material being connected therewith.
Description of Prior Art Sacks or bags of this kind are for instance known from the German Utility Models 81 15 909 and 82 07 889. Said known sacks or bags, however, show the drawback that the leg-like strips forming a bottom leaf, so to speak, which in their middle region are connected with ~he web section being provided with the griphole, are glued with the bottom all-over or nearly all-over, so that through the web section, i.e. in the region of the longitudinal center plane running through the bot-tom of the sack, considerable strains are exercised on the bo~tom during carrying, said strains resulting from the fact that the forces exercised by the web section are introduced therein substantial ly in the region of a line centrically extending through the bot-tom square.
Summary of the Invention It is an object of the invention to provide a sack or bag o the kind mentioned hereinbefore, in which the bottom itself is relieved to a large degree of the carrying forces which are introduced through ~he web section having the griphole.
37~
This problem is solved according to the invention for a sack or bag of the generic type by the fact that the bottom moun-ted thereon is conventionally glued or welded to a leaf connect-ed sealingly with the inner ed~es of the corner tucks and at least with the inner edges of the side tucks adjacent to their fold lines, that the handle portion is inserted in the still open bottom, and that the leg-like strips thereof are at least partially covered by the side tucks and glued or welded thereto.
In the sack or bag according to the inven~ion, the side of the lateral leg-li~e strips of the handle portion ~acing the leaf constituted by e.g. a piece of paper or foil, wherein said strips carry in the center thereof the web section having the griphole, is not glued to said leaf, but the side tucks overlap the lateral leg-like strips and are glued or welded thereto at the sides thereof at which also the middle web section with -the griphole is located. The sack or bag according to the invention, therefore, is characterized by a tunnel which is formed between the lower side of the handle portion and the outer side of the leaf. Due to this structure, through the middle web section and the leg-like strips connected therewith, the carrying forces are substantially directly introduced into the side walls of the filled sack, so that ~he handle portion can accept considerably greater carrying forces without the sack being damaged thereby or bottom parts being strippsd thereoff.
- Advantageously, the corner tucks are formed a~ least along a portion of their width by parallel slits in the flat tube piece which constitutes the workpiece for the production of the sack nr bag.
~,~
According to a fur~her aspect of the invention it is pro-vided that one side tuck is shorther than another so that corre-sponding holding strips are obtained for sack workpieces severed 3'~7 from a tubular web at opening edges opposite to the ~ottoms.
According to another aspect of the present invention it is provided that the handle portion consists of a cu-t being fold-ed on itself, from the middle part thereof, which forms the web section, the leg-liks strips are separated by fold lines.
The leg-like strips can at least be backfolded on them-selves along a part of their length. The parts can also be back-folded on themselves to such an extPnt that they overlap each other.
Moreover, to the lower side of the leg-like strips of the handle portion an enforcement leaf can be attached which at least part-ially covers both.

Detailled Description of Prsferred Embodiments Fig. 1 shows a tube portion 1 severed from a tubular web of paper or thermoplastic synthe~ic resin and constituting the basic workpiece for the production of the sack. At its upper edge, the tube portion 1 is provided with two slits 2 being in parallel to each other and with respect to the lateral fold edges, the slits 2 having nearly the same distance to the later-al fold edges 3. Whila the cutting edge is aligned between the lateral slits 2 of the upper wall wi~h the lateral parts, the lower cutting edge 4 is displaced by the amount a to the inside between the lateral slits 2 so that a corresponding edge strip is obtained at the opposite lowar side wall of the sack work~
piece.
Fig. 2 shows the sack workpiece according to Fig. 1 with a bottom conventionally mounted thereon. By the mounting the cor-ner tucks 5 and tha side tucks 6, 7 are obtained, the side tuck 6 being smaller by the width of the edge strip 8 than the side tuck 7. The side tucks 6, 7 are partially separated from the cor-ner tucks 5 by the cutting lines 2. In the later closing of the bottom, the side tucks 6, 7 are folded at the pregrooved lines 9, 10.
On the mounted so-called bottom square according to Fig.
2, the rectangular leaf 12 is put which covers the inner parts 13 of the corner tucks 5 and the parts of tha side tucks 6, 7 being adjacent to the grooved fold linss 9, 10. The leaf 12 is totally glued or welded to the parts 13 of the corner tuc~s and `! ~
the inner regions of the side tucks 6, 7, so that the bottom is sealed thereby.
On the thus prepared but still open bottom then the hand-3~7 ~ 6 le portion is put, namsly the lateral leg-like strips 16, 17 joined through lower fold lines to the middle web section 15, which together form a rectangular sheet covering the leaf 12 in the region of the corner tucks 5 with edge strips of the width b.
The condition of the sacks according to Fig. 3 and 4 is now further explained for clarification's sake on the basis of Fig. 5 and 6. As can be seen from Fig. 5, the leaf 12 is put on the mounted and flat bottom in form of a rectangular leaf and is glued thereto in the described manner. Thereby the leaf 1~
covers the inner edges of the side tucks 6, 7. Furthermore, the leaf 12 covers the inner parts 13 of the corner tucks, the edges of which can be seen in the top plan views of Fig. 5 and 6.
According to Fig. 6, additionally a handle portion accord-ing to Fig. 11 is put on the leaf 12.
When the bottom section is prepared in the manner as can be seen from Fig. 4, the side tucks 6, 7 with the glued leafs 12 are folded at the fold lines 9, 10 on-to the outer sides of the leg-like strips 16, 17 of the handle portion on both sides of the middle web section 15 and glued thereto. Therein, in the manner as can be seen from Fig. 8, the smaller side tuck 6 ex-tends approximately up to the middle web section 15 of the hand-le portion, whereas the broader side tuck 7 extends along a part of the middle web section 15.
The handle portion according to Fig~ 10 consists of -the middle web section and the adjacent leg-like strips 16, 17, wherein centrically an enforcement strip ~0 i5 glued to the back side, the length of which corresponds to the length o the hand~
le portion.
- 7 - ~ ~ ~ O ~ ~
In the handle portion according to Fig. 11, the lateral strips 16, 17 are designed to be broader and are revers~ly fold-ed to the inside onto themselves so that they overlap each other in the area of the web section 15.
In the embodiment according to Fig. 12, additionally an enforcement strip 21 is inserted in the edge strips of the leg-like strips 15, overlapping each other and being inwardly fold-ed, wherein the enforcement strip 21 is only glued to -the upper part on one side. Fig. 14 shows an embodiment which is similar to that of Fig. 12. In this case, however, the adhesive beam is displaced with regard to the sides. In the two embodiments ac-cording to Fig. 12 and 14, the lower section o* ~he handle port-ion forms the leaf, the tunnel being formed between the enforce-ment leaf 21 and the lower section. Consequently, in these embo-diments the use of a leaf is unnecessary.
In Fig. 13 an embodiment is shown in which the leg-like strips are at least backfolded along a part of thslr length onto themselves.
I n Fig . 9 there is shown a sack with the handle portion in a filled state. The side tucks 6, 7 are folded onto the later-al leg-like strips of the handle portion and glued thereto. This results in a flat, tunnel-like passage 25 between the lower side of the leg-like strips 16, 17 and the leaf 12, the passage 25 being formed by the fact that the parts being adjacent to the middle web section 15 form tension straps, so to speak, which ~.i introduce the carrying forces into the side walls of the filled sack.
However, it is advanta~eous to not weld or glue at least - 8 - ~ 377 the upper layer of the leg-like strips with the parts being tuck-ed or overlapping each other so that the tunnel-like formation can still be obtained which results in the favourable introduct-ion of the carrying forces into the side walls.
the inner regions of the side tucks 6, 7, so that the bottom is sealed thereby.
On the thus prepared but still open bottom then the hand-3~7 ~ 6 le portion is put, namsly the lateral leg-like strips 16, 17 joined through lower fold lines to the middle web section 15, which together form a rectangular sheet covering the leaf 12 in the region of the corner tucks 5 with edge strips of the width b.
The condition of the sacks according to Fig. 3 and 4 is now further explained for clarification's sake on the basis of Fig. 5 and 6. As can be seen from Fig. 5, the leaf 12 is put on the mounted and flat bottom in form of a rectangular leaf and is glued thereto in the described manner. Thereby the leaf 1~
covers the inner edges of the side tucks 6, 7. Furthermore, the leaf 12 covers the inner parts 13 of the corner tucks, the edges of which can be seen in the top plan views of Fig. 5 and 6.
According to Fig. 6, additionally a handle portion accord-ing to Fig. 11 is put on the leaf 12.
When the bottom section is prepared in the manner as can be seen from Fig. 4, the side tucks 6, 7 with the glued leafs 12 are folded at the fold lines 9, 10 on-to the outer sides of the leg-like strips 16, 17 of the handle portion on both sides of the middle web section 15 and glued thereto. Therein, in the manner as can be seen from Fig. 8, the smaller side tuck 6 ex-tends approximately up to the middle web section 15 of the hand-le portion, whereas the broader side tuck 7 extends along a part of the middle web section 15.
The handle portion according to Fig~ 10 consists of -the middle web section and the adjacent leg-like strips 16, 17, wherein centrically an enforcement strip ~0 i5 glued to the back side, the length of which corresponds to the length o the hand~
le portion.
- 7 - ~ ~ ~ O ~ ~
In the handle portion according to Fig. 11, the lateral strips 16, 17 are designed to be broader and are revers~ly fold-ed to the inside onto themselves so that they overlap each other in the area of the web section 15.
In the embodiment according to Fig. 12, additionally an enforcement strip 21 is inserted in the edge strips of the leg-like strips 15, overlapping each other and being inwardly fold-ed, wherein the enforcement strip 21 is only glued to -the upper part on one side. Fig. 14 shows an embodiment which is similar to that of Fig. 12. In this case, however, the adhesive beam is displaced with regard to the sides. In the two embodiments ac-cording to Fig. 12 and 14, the lower section o* ~he handle port-ion forms the leaf, the tunnel being formed between the enforce-ment leaf 21 and the lower section. Consequently, in these embo-diments the use of a leaf is unnecessary.
In Fig. 13 an embodiment is shown in which the leg-like strips are at least backfolded along a part of thslr length onto themselves.
I n Fig . 9 there is shown a sack with the handle portion in a filled state. The side tucks 6, 7 are folded onto the later-al leg-like strips of the handle portion and glued thereto. This results in a flat, tunnel-like passage 25 between the lower side of the leg-like strips 16, 17 and the leaf 12, the passage 25 being formed by the fact that the parts being adjacent to the middle web section 15 form tension straps, so to speak, which ~.i introduce the carrying forces into the side walls of the filled sack.
However, it is advanta~eous to not weld or glue at least - 8 - ~ 377 the upper layer of the leg-like strips with the parts being tuck-ed or overlapping each other so that the tunnel-like formation can still be obtained which results in the favourable introduct-ion of the carrying forces into the side walls.
