This invention relates to improvements in the manufacture of containers, having particular reference to a knock down or collapsible type container in which an inner liner, constituting a flat bottom bag having reentrant folds, is secured therein in such a manner that. upon squaring the container, the bag automatically is opened for filling with any desirable commodity. and the provision of such a container is a principal object of the invention.
More specifically, it is an object of the invention to provide a knock down or collapsible type or container by means of a cut and scored blank of reenforcing material having panels secured together to provide side walls with automatic bottom closure sections, and an inner bag having a fiat bottom and side walls with reentrant folds which is secured at its flat bottom to one of the bottom closure sections of the blank and at one 'of its reentrant folds to a side wall panel, so that the panels. upon being squared, will automatically close the bottom closure section and automatically open the bag for filling purposes.
Other objects of the invention will in part be obvious and will in part appear hereinafter.
The term flat bottom bag is intended to have its conventional meaning in the industry, 1. e., that type of bag which is generally rectangular or generally square across its bottom, which bottom is folded fiat against one of the side walls before the bag is opened, and which bottom has the side walls perpendicular thereto after the bag is opened.
The invention accordingly comprises a knock down or collapsible type-of container possessing the features, properties, and the relation of elements which will be exemplified in the container hereinafter described and the scope of the application of which will be indicated in the claims.
For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawings, in
which:
Fig. 1 is a plan view of a preferred form of cut and scored blank useful in practicing the present invention;
Figs. 2, 3, 4 and 5 are perspectiye views of lower portions of one type of fiat; bottom bag with reentrant folds, illustrating a novel and preferred vmanner of folding the same for use in conjunction with the present invention;

Fig..10 is a cross-sectional view of a completed container in squared position ready for filling;
Fig. 11 is a plan view of the bottom of the container shown in Fig. 10 illustrating the bottom closure sections in closed and braced position.
Fig. 12 is a transverse view taken along the lines l2-l2 of Fig. 11; and
Fig. 13 is a transverse view taken along the lines l3-l3 of Fig. 12.
Referring more particularly to Fig. l of the drawings, there is indicated generally at ill a preferred form of cut and scored blank adapted for use in practicing the present invention. This blank has a. vertical set of score lines 2|, 22, 23 and 24, and these score lines divide the blank into panels or side walls 25, 26, 21 and 28. At one end of the blank is a glue flap 29. The panels or side walls 25 to 28. inclusive. have bottom closure sections 30, 3|, 32 and 33 respectively. The section 30 has a, score line 34 dividing the same into portions 34a and 34b. The section 32 has a score line 35 dividing the same ,into portions 35a and 35b. The section the same into portions 36a and 381).
At the other end of the panels 25 to 28 are top closure extensions 31, 38 and 39, the latter having a tuck-in flap 40. Any suitable form of top closure may be used with the present invention and the panels herein illustrated as the top closure may be omitted entirely as will morefully appear hereinafter. For example, any conventional type of cover or other suitable closure can be substituted.
Container blanksthus cut and scored preferably are run through a straight line gluing machine, although any suitable means of applying predetermined spots of glue may be utilized. In any cardboard blank together preferably is applied to glue flap 29, section 30, section 3!, and portion 350 of section 32 as more fully indicated by the stippling in the drawings. In addition to this, a strip of glue should be applied to at least two adjacent panels, preferably as indicated at M and 42 on the panels 25 and 26, respectively.
Referring now to the group of Figures 2 to 5,
33 has a "score line 36 dividing asaasee' v 3 d inclusive. it will be seen that there is illustrated a conventional type of flat bottom bag having gussets, or reentrant folds, in its side walls. This type of bag is so well known that it needs but little discussion. However, in using such a bag to practice the present" invention, an alteration of the reentrant folds is essential. It will be ob served in Fig. 3 that the bag of Fig. 2 has had the bottom portion thereof folded upwardly against one of the side walls. Thereafter a corner 43 is folded downwardly along a diagonal line as indicated in Fig. 4. As this folding occurs one of the adjacent reentrant folds 44 is folded back against the side wall adjacent thereto, also as indicated in Fig. 4. Thereafter, the corner 43 is again folded back into its original position but the reentrant fold 44 is caused to remain against I the adjacent side wall of the bag.
The bag as thus illustrated in F g. 5 is now positioned on the panel 25 of the blank Ill. The opposite side wall of the bag will be secured to the panel by means of the adhesive 4!. The bottom section-30 is next folded against the flat bottom of the inner bag and because of the adhesive which has been applied to the section 30 is caused to adhere to the flat bottom of the bag.
The blank I0 is now folded over and the glue-applied section 3| is secured to the bottom of the portion 34a of the section 30. As the folding of the panels 26, 21 and 28 is continued, the underside portion 36b of the panel 33 is secured to the glue-applied portion 35a of the section 32 and both bottom sections 32 and 30 move inwardly and overlie their respective panels 21 and 25. At this point in the folding operation the panel 28 is brought into contact with the glue-applied section of the glue flap 29 and the latter is secured to the panel 28.
After this folding and gluing operation has been completed it will be observed that the bottom closure sections are allprojecting into the container when in knock down position, as indicated in Fig. 8. It now will be observed that the bottom closure sections constitute inner layers 30 and 3| hinged to each other, and outer layers 32 and 33, also hinged to each other. In the meantime, the panel 26 becomes secured across the opened reentrant folds of the inner bag by means of the adhesive 42. After the bag has been glued together in this manner it will appear as indicated in cross-section in Fig. 9, where the position of the opened reentrant fold glued to the side panel 26 by adhesive 42 can now more particularly be seen.
The bag in this condition is now ready to be filled. It is but necessary for an operator to squeeze diagonally opposite vertical edges, as in dicated by the arrows 45, 45 in Fig, 9. In this manner. the panels of the container can be brought into squared position and, because of the fact that one side wall of the inner bag is tions are hinged with respect to each other beable; an operator to insert a filling nozzle or spout from which any suitable or desirable type of material can be injected into the container. As
this filling operationproceeds, the bottomclosure sections including the inner bag are snapped into final position by the weight and force of the material and the sides of the has not secured to the remaining portions of the panels 21 and 28am extended to the positions indicated by the dotted line 48 in Fig. 10.
After the bag has been filled with the desired amount of commodity. the top may be sealed in any suitable manner depending on the type of material that is used to form the inner bag. Such material for liners or inner bags may be made of Cellophane, pllofilm, glassine, parchment, or
' laminated similar or dissimilar materials of these secured by the adhesive 4! to the panel 25, and v the opened gusset or reentrant fold 44 is secured by means of the adhesive 42 to the panel 26, the inner bag will automatically be opened substantially to the position indicated in Fig. 10 of the I types, preferably having heat-sealing characteristics. After the bag is closed at the top it can be folded and tucked into the top of the container and the cover extensions 33 to 39 placed in position, as indicated in Figs. 12 and 13.
It will thus be seen that the objects hereinbefore set forth may readily and eiilciently be attained, and since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
