Definitions

  • Bockenek Att0rney-lmirie and Smiley ABSTRACT The invention provides a collapsible bag coms prising a prismatic, tubular body having hingedly connected g wall panels so as to be collapsible to flat condition, and hinged [52] US. Cl 229/54, flaps at the ends of the tube to constitute the bottom and the 229/52, 229 /53 top of the bag, all parts being kept in interlocking relationship [51] Int. Cl B65d31/16, by means of a carrying strap introduced between the top flaps B65d 33/06 and the bottom flaps.
  • This invention relates to collapsible bags provided with a carrying strap which may be used as shoulder strap, for example.
  • Collapsible bags known heretofore are generally made of soft tissue which may be rolled or folded up, and are permanently connected with a carrying handle or strap. Such bags offer little protection to the objects contained therein. Bags having stiff walls so as to be capable of protecting their contents against shocks and external pressure, are not collapsible.
  • Collapsible packaging containers made of corrugated paper board, or the like, and having stiff walls and bottom, are known, but such containers are not suited for use as handbags, i.e. because they have no carrying handle or strap. Furthermore, once such containers are folded up, the bottom thereof, at least, must be permanently secured in its operative position in order to be able to carry the load of the goods packedin the container, so that the latter is no more collapsible.
  • Another object is to provide a collapsible bag having hingedly connected stiff panels for constituting the walls, the bottom and the lid thereof, and a strap for carrying the bag and locking the bottom of the bag against bursting open under the action of the weight of the object contained in the bag.
  • a further object is to provide a collapsible bag of the kind described having a separate carrying strap which becomes operatively connected with the body of the bag when the flaps or panels constituting the bottom and the lid of the bag are folded in to close the ends of the tubular body of the bag.
  • Still another object is to provide a collapsible bag with stiff walls and bottom which is simple in construction and inexpensive to make.
  • FIG. 1 illustrates a portion of a foldable blank for the bag of this invention
  • FIG. 2 is as top perspective view of the bag made from the blank of FIG. 1 and provided with a strap
  • FIG. 3 is a bottom perspective view of the same
  • FIG. 4 illustrates a modified form of the blank shown in FIG. 1,
  • FIG. 5 is. an end view of the bag made from the blank of FIG. 4.
  • the blank shown in FIG. 1 may be made of any suitable, stiff sheet material which is made pliable at the folding lines discussed hereinafter.
  • Such materials are, for example, leather, plastic sheets, paper board or like fibre material, especially if coated with tissue.
  • the various panels defined between the folding lines of the blank may be made separately and be hingedly connected with each other along the folding lines by means of the tissue coating.
  • the blank shown in FIG. 1 is first folded along parallel folding lines 3, 2 and 4 to constitute a prismatic tube having rectangular wall panels 31, 32, 31a and 32a, the tube being closed along the edge 1, e.g. through heat sealing in case of a blank of heat-sealable material.
  • the edge 1 will then constitute a folding line of the tube.
  • the tube When collapsed to flat condition, the tube comprises two equal portions defined between the folding lines 1 and 2 lying flat upon each other. Near each end, the tube is provided with transverse folding lines 5, 6, 7, 8 and 9, 10, 11, 12, respectively defining flaps or panels 33, 34, 33a, 34a and 35, 36, 35a, 36a, respectively, for folding in to constitute a closure at each end of the tubular body of the bag.
  • the flap or panel 33 defined between the folding lines l, 3 and 5 (FIG. 1, upper left) is formed with a pair of additional folding lines 13 and 14 starting at the point of intersection between the folding lines 1, 5 and 3, 5, respectively, and extending under an angle of 45 with these folding lines.
  • the flap 33 is formed with a recess 21, the lateral edges of which meet the inclined folding lines 13 and 14 at points spaced a distance which is slightly greater than the width of the carrying strap described hereinafter.
  • the recess 21 maybe formed in any desired manner. In the example illustrated, the recess 21 is shown as being trapezoid.
  • the area defined between the inclined folding lines 13 and 14 should have a width at right angles to the folding line 5 which is smaller than half the length of the flap along the folding line 5, so that the folding lines 13 and 14 do not intersect each other.
  • the flat, collapsed tube When the flat, collapsed tube is to be used as a bag, it is folded to rectangular section, and the flaps 34, 34a and 36, 36a are folded in to constitute the lid and the bottom respectively, of the bag, as shown in FIGS. 2 and 3, while the flaps 33, 33a and 35, 35a remain in a projecting position.
  • these flaps When folded along the inclined folding lines 13-20, these flaps constitute closed channels or guideways through which a carrying strap 25 is threaded.
  • This strap may take the form of an endless belt or loop, or it may be provided with a buckle or clasp (not shown) for adjusting the length of the strap.
  • the strap may be placed in the body of the bag before or after fold ing in of the top and bottom flaps 34, 34a and 36, 36a as desired, but in any case it should be caused to extend through the channels or guideways formed by the flaps 33, 33a and 35, 35a and along the inside of the wall panels 31 and 31a
  • a portion ofthe strap 25 will extend from one end of the bottom 36, 36a of the bag to the other (FIG. 3), and when the strap is pulled away from the top side of the bag, the channels or guideways formed by the flaps 35 and 35a are bent in towards the outside of the bottom panels 36 and 36a.
  • the strap 25 may be pulled in the opposite direction relative to the body of the bag, so that the flaps 34, 34a constitute the bottom and the flaps 36, 36a constitute the top of the bag.
  • FIG. 4 differs from that shown in FIG. '1 in that slots 27, 28, 29 and 30 are provided along part of the foldinglines 5,7, 9 and 11, respectively, through which slots the strap 25 may pass from the inside of the flaps 33, 35 and 33a, 35a to the outside of the wall panels 31 and 31a, respectively, as shown in FIG. 5.
  • This measure will assist in keeping the carrying strap 25 positioned when the top of the bag is open.
  • the width of the top and bottom flaps 34, 34a and 36, 36a at right angles to their respective folding lines 6, 8, 10, 12 should be greater than half the width of the wall panels 31, 31a, and smaller than this width, so as to insure a suitable overlapping, as shown in FIG. 2.
  • the lateral margins of the lid flaps 34, 34a and bottom flaps 36, 360 are coincident or coextensive with the lateral hinge margins 2-4. Additionally, the end walls 31, 31a have hingedly connected to the upper margins 5, 7 and bottom margins 9, 11 a series of polygonal segments conveniently described as sleeve-forming channels which are clearly illustrated in FIGS.
  • the sleeve-forming channels comprise a pair of isosceles triangular segments hingedly connected to the lateral margins of the rectangular lid flaps, see FIGS. 1 and 4, and include lower hinge margins at l320, each respectively comprising opposite sides of a trapezoidal segment 33, 33a, and 35, 350, respectively.
  • These trapezoidal segments have their longer base 5, 7, 9, and 11, respectively, hingedly connected at the upper or lower ends of the end walls 31, 31a.
  • a foldable-flat bag comprising a cubical, tubular body including alternate pairs of side and end wall panels hingedly connected at lateral edges for forming a tubular body when erected:
  • closure flaps having lateral hinge margins coincident with the lateral marginal edges of said sidewall panels therebeneath;
  • sleeve-forming channels comprising segments hingedly connected to respective upper and lower marginal edges of said end wall panels
  • said sleeve-forming channels comprising pairs of segments hingedly connected at one edge to the lateral hinge margins of said rectangular lid and bottom closure flaps;
  • pairs of segments converging at hinge lines bordering an intermediate segment hinged to the respective upper and lower edges of said end wall panels;
