Definitions

  • This invention relates to improvements in flexible bags that are provided with closures through which articles for support may pass and from which articles may be removed.
  • Bags provided with closures through which articles for support may pass and from which articles may be removed have been widely accepted.
  • a typical example of such a bag is shown in U. S. Patent No. 2,428,227 to Kase. The ends of the surfaces do overlap to form a closure but only one seal is formed. Furthermore, it is overly complex and difficult to manufacture due" to the number of unrelated parts.
  • Another example of such a bag is shown in U. S. Patent No. 2,291,414 to Slobotkin.
  • U. S. Patent No. 3,462,764 to Caster the patentee shows a pocket with an elastic!zed flap placed over a pocket and secured above and to the sides of the pocket. Again just one seal is formed.
  • a bag is com ⁇ prised of a single sheet of flexible material having two ends and two edges or sides (herein referred to as edges) folded parallel to the ends to provide front and back sur ⁇ faces that are sealed together along the edges to provide a pocket.
  • Each of the two surfaces extends toward an opening into the pocket through which articles for support may pass and from which articles may be removed.
  • One of these sur ⁇ faces extends beyond the opening to the bag and is folded over the end of the other surface to form a flap which is sealed along its edges to the edges of the bag. The only opening into the bag is between the folded over end and the end of the adjacent surface.
  • An elastic strip under tension and rubber like foam material are encased in the two ends and connected to the sealed edges of the bag.
  • the elastic strips and rubber like foam material in the ends forming the opening act toward the surfaces of the bag to close the opening thereto, while at the same time acting toward each other.
  • Fig. 1 is a perspective view of the bag prior to being stretched lengthwise. The ends forming the opening into the bag are separated to show detail. The arrows show the direction in which the bag is stretched lengthwise and folded to join the sealed edges together.
  • Fig. 2 is a perspective view of the bag of the inven ⁇ tion stretched lengthwise and mounted about a form. The ends forming the opening into the bag are in the closed position.
  • Fig. 3 is a cross-sectional perspective view along line 3-3 of Fig. 2 but with flap end and adjacent surface end extended outward slightly opposite the direction of the arrow for the purpose of showing increased detail. Best Mode For Carrying Out The Invention
  • a bag 4 comprising a single sheet of fabric.
  • the edges 10 and 11 of the bag 4 are sealed together by one or more rows of stitching 8.
  • the ends 5 and 6 of the continuous sheet of fabric define the opening into the bag 4.
  • Stitching 8a forms a border along the ends 5, 6 and fold 7 which are sealed to the edges 10 and 11 by stitching 8.
  • Also disposed along the sealed edges 10 and 11 are strips of hook and loop fasteners 9 attached by stitching 8.
  • An elastic strip under tension and rubber like foam material are held captive in each of the borders along ends 5 and 6 which define the opening into the bag and along fold 7 which forms the bottom of the bag.
  • the bag 4 When the bag 4 is stretched lengthwise in the direction of the arrows, it may be wrapped around a form and fastened to ⁇ gether sealed edge to sealed edge by mating the surfaces of the hook and loop fasteners 9 as shown in Fig. 2 wherein the bag 4 acquires a tubular shape conforming to the calf por ⁇ tion of a human leg (dotted lines) in the upper region 14 of the bag 4 and conforming to the top of a boot 13 at the lower region 12 of the bag 4. Only the borders formed by stitching 8a along end 5 and fold 7 are visible. The other end 6 of the bag 4 which forms a part of the opening to the bag is hidden from view, surrounded by and disposed above end 5.
  • Fig. 3 the bag 4 is shown in considerable detail.
  • the end 5 of flap 17 and the end 6 on surface 15 have been extended outward to make it easier to identify the component parts. Were the aforementioned parts not separated for the purpose of clarity, they would all be drawn together when the bag 4 is stretched lengthwise and mounted around a form in the direction of the arrow with no spacing between surface 15 and 16 above the lowermost portion of end 5.
  • the bag comprises a single sheet of flexible material having a fold 7 to provide a front surface 15 and a back surface 16 which are sealed together along the edges of the bag to provide a pocket 18.
  • Each of the surfaces 15 and 16 extends toward the opening of the pocket through which an article 25 for support may pass and from which article 25 may be removed.
  • the elastic strips 19, 20 and 21 are all positioned inwardly of the foam rubber like material 22, 23 and 24, respectively, relative to the opening of the pocket 18 to facilitate frictional engage ⁇ ment against surfaces 15 and 16 when the bag 4 is stretched lengthwise in the direction of the sealed edges 10 and 11.
  • End 5 and end 6 are positioned one on top of the other in a nested relationship when they are fastened to the sealed edges of the bag, thereby permanently join ⁇ ing their outer edges but permitting free movement between the sealed edges, one relative to the other, to permit access to the pocket 18.
  • the elastic strip 20 in end 5 is under greater tension than the tension of the elastic strip 19 in end 6.
  • the greater tension in elastic strip 20 in end 5 enables end 5 to act upon surfaces 15 and 16 with greater force than end 6 upon surface 16 when the bag is stretched lengthwise and maintained stretched.
  • the lesser tension in end 6 enables it to be pulled downwardly when an article 25 is placed in the pocket 18 which in turn extends an outward force on surface 15, thereby forming a pressure seal between the lower portion of end 6 and the upper por ⁇ tion of the overlapping end 5 which acts with considerable force against surface 15 and surface 16 in thedirection of the arrow, thereby preventing the end 6 from any further down- ward movement beyond the seal against the upper portion of end 5.
  • the rubber like (compressible and stretchable) foam 22, 23 and 24 runs substantially the entire length of the ends 5 and 6 and the fold 7.
  • the rubber like foam in addition to providing the desired overlapping and nesting thickened ends also acts to prevent the fabric forming the casings around the elastic strip from bunching up along the length of the ends 5 and 6 and the fold 7.
  • the foam rubber like material 22 and 23 has a substantially rectangular cross-section as shown in Fig. 3 to increase the frictional engagement between the upper portion of end 5 and the lower portion of end 6 when the bag 4 is stretched lengthwise in the direction of the sealed edges and main ⁇ tained stretched.
  • Foam rubber like material 24 has a sub- stantially rectangular shape in cross-section for cosmetic symmetry among the three foam rubber portions 22, 23 and 24.
  • the foam rubber like material 22, 23 and 24 may be utilized alone and the elastic strips 19, 20 and 21 may be omitted.
  • any object placed in the bag must pass through four distinct closed regions to exit the bag.
  • the first region is where end 5 acts against surface 15 and surface 16 in Fig. 3.
  • the second region is where end 6 acts against surface 16.
  • the third region is where the lowermost surface of end 6 con- tacts theuppermost surface of end 5, and the fourth region is where end 5 acts against surface 15.
  • a flexible bag of this invention is joined together along its sealed edges to form a continuous tube which is stretched around a form.
  • the sealed edges of the bag be connected end to end to actualize the benefits of the resealable closure means of this invention.
  • the bag be utilized in such a fashion that the opposite sealed edges are extended lengthwise and then attached to a flat surface or by mounting the sealed edges of the bag between two stationary objects after the sealed edges have been stretched lengthwise. While either the flat elastic strips 19, 20 and 21 or the foam rubber like material 22,.23 and 24 may be omitted, the combination of the elastic strips 19, 20 and 21 and the foam rubber material 22, 23 and 24 provides the best results.
  • specific materials have been suggested in the pre- ferred embodiment, other similar materials could be substi- . tuted without departing from the scope of the invention.

Abstract

Un sac (4) est formé en une seule feuille d'un matériau flexible ayant deux extrémités (5, 6) et deux bords (10, 11), pliée parallèlement aux extrémités (5, 6) afin de former des surfaces antérieure et postérieure (15, 16) qui sont scellées ensemble le long des bords (10, 11) afin de créer une poche (18). Chaque surface (15, 16) s'étend jusqu'à une ouverture de la poche (18) à travers laquelle des objets peuvent être introduits pour être conservés dans la poche ou peuvent être enlevés. Une des surfaces (16) s'étend au-delà de l'ouverture de la poche (18) et est repliée par-dessus l'extrémité (6) de l'autre surface (15). L'extrémité (5) de la surface repliée (16) se situe directement au-dessous de l'extrémité (6) de l'autre surface (5), à l'extérieur du sac (4), et des éléments élastiques (19, 20) sont enfermés à l'intérieur des extrémités (5, 6) de sorte qye lorsqu'on étire le sac (4) vers les bords scellés (10, 11) et que l'on maintient le sac (4) en position étirée une pluralité de fermetures se forment pour fermer l'ouverture du sac (4). En outre, lorsque l'on joint un bord scellé (10) du sac (4) à l'autre bord scellé (11), et que l'on étire le sac (4) autour d'une forme (14), les extrémités étirées (5, 6), qui forment l'ouverture du sac (4) le soutiennent également autour de la forme (14).
