Definitions

  • the present invention relates generally to a package, system and method for packaging of an article and, more particularly, to an inflatable package havin'g a clam-like configuration adapted to compress and retain the article therein, e.g., where chambers surround the article, are supplied with a filler medium and exert equal pressure about the article.
  • a first general embodiment of the present invention comprises a package including a plurality of inflatable portions which are arranged to form a pocket for receiving and retaining an article.
  • a filler medium supply portion is coupled to all of the inflatable portions for enabling the inflatable portions to be inflated under equal pressure with a filler medium and thereby for substan ⁇ tially encapsulating the pocket and the article therein.
  • Second and third general embodiments of the present invention comprise overlying first and second bag portions pivotally and flexibly connected together to a third bag portion at a rearward side of the packaging system.
  • a fourth bag portion is connected to the first or second bag portion at a frontal side.
  • the interiors of all of the bag portions are interconnected so that they may be simul- taneously inflated from a single inlet in one of the bag portions.
  • Overlying edges of the first and second bag portions are secured together at their opposite lateral sides to form a pocket for reception of an article, with the first and second bag portions remaining unattached to each other at a frontal side of the packaging system to expose the pocket therebetween.
  • a flap terminates the fourth bag portion and is insertable into the pocket and over the article enclosed therein.
  • Inflating means are preferably provided on the packaging system at least to partially fill all of the bag portions with a filler medium, such as pressurized art, and to compress the first and second bag portions against the article.
  • the inflated fourth bag portion of the third general embodiment also helps seal off the entry to the pocket, and all four inflated bag portions form a fully surrounding protection for the enclosed article.
  • the flap may also be inflated to add extra security to the enclosed article. When inflated, all bag portions place their ⁇ ' pocket- forming components under orthogonally-directed tension to securely clamp the article within the pocket.
  • the peripheries of four layers of fluid impermeable material are bonded and sealed together except for a peripheral portion which provides an entry through which the article can be inserted into the pocket.
  • the peripheral entry portion is formed by respective couplings between the upper two layers and between the lower two layers.
  • the upper two and the lower two layers at the peripheral portion may also be wholly or partially bonded and sealed together to secure the article into the thus- formed package.
  • the inflatable portions are -then filled and
  • _ * _ inflated with air or other suitable medium to suspend ' the two interior layers and the pocket formed thereby 'at a fixed position within the two layers.
  • air in the pocket is forced out past the partial seal upon inflation of the inflat ⁇ able portions and, therefore, enables the two interior layer portions to press against the article.
  • another peripheral portion is formed into the supply portion with at least two separated entries into all of the inflate able portions.
  • the bifurcated air passage is fanned by sealing the four layers completely together, but leaving unsealed spaces between the opposed ends of the seal line and the sealed periphery.

  • chambers 332, 334, 336 and 337 expand, moving panels 340a and 342a, 340b and 342b, 340c and 342c, and 340d and 342d away from one other, as a comparison of Figs. 21 and 22 illustrates.
  • panels 340a and 340b press against and about article 326
  • panels 340c and 340d press against panels 340a and 340b, as permitted by the separation of pairs of seams 318 which define portion 316 and its chamber 336 and by the separation of »pairs, of seams 318 and 329 which define portion 317 and its chamber 337.
  • the segments of panels 340a and "340b adjacent front seams 328 and 329 also press against one another and seal article 326 within pocket 324.
  • portion 317 expands against seam 328 to help ⁇ loste off the pocket.
  • the internal pressure also presses against tube 339 of valve 338 to maintain it closed and to prevent escape of air from package 310.
  • gases such as helium
  • a suitable liquid such as water
  • the chamber may be filled with a plastic material such as of urethane and polystyrene, in solid form, as injected in liquid form and solidified or as pieces, e.g., balls or pellets or combinations of all these and other filler media.
  • a solid filler medium of the type described above, it may be desirable to pre-pack such filler medium into the chambers prior to forming one or more of edge portions or seams or to provide a separate inflating means or valve for communicating the filler medium to each chamber individually.
  • each seam 318 would be extended the full width of the package to place the chambers out of communication with respect to one another.
  • full seam 329 may be made like seams 318, so that flap portion 319 will also inflate and expand against article 326 and against sections of bag portions 312 and 314 and, therefore, more fully trap the article within pocket 324.

Abstract

Un système de conditionnement (20, 210, 310) comprend une première partie de sac (34, 212, 312) définissant une première chambre latérale gonflée (42, 232, 332), ainsi qu'une seconde partie de sac (36, 214, 314) définissant une seconde chambre latérale gonflée (44, 234, 334), lesdites parties de sac se recouvrant mutuellement pour définir une poche (26, 224, 324) entre elles, dans laquelle un article comprimé (28, 226, 326) est contenu. Dans un second mode de réalisation général, lesdites parties de sac sont reliées pivotantes à une troisième partie de sac (26) définissant une troisième chambre latérale gonflée (236) sur un côté arrière du système. Dans un troisième mode de réalisation général, les parties de sac sont reliées pivotantes à des troisième et quatrième parties de sac respectives (316, 317), définissant des troisième et quatrième chambres latérales gonflées (336, 337) sur les côtés arrière et avant dudit système. Les intérieurs des chambres de toutes les parties sont reliés (50, 218a, 218b, 318a, 318b). Les parties de bordure de couverture (38, 40, 244, 246, 344, 346) des première et seconde parties de sac sont thermo-soudées au niveau des côtés latéraux opposés (38, 40, 220, 320, 322) dudit système de conditionnement. Le côté frontal (30, 228, 230, 328, 330) du système de conditionnement est ouvert pour permettre l'insertion de l'article dans la poche.
