l n INFLATABLE PACKING INSERT' Filed March 23, 1966 United States Patent O 3,346,101 INFLATABLE PACKING INSERT John A. Pestka, Park Ridge, Ill., assignor to Warwick Electronics Inc., a corporation of Delaware Filed Mar. 23, 1966, Ser. No. 536,821 9 Claims. (Cl. 206--46) ABSTRACT OF THE DISCLOSURE An inflatable packing insert for protecting a heavy article in a shipping container against shock comprising a sleeve-like member with spaced inflatable cells disposed to lie adjacent the corners of the article so as to protect the article without being pinched thereby. Also, the fluid inllation passage is disposed along one edge of the sleevelike member so as to normally lie outside of the article being protected. f
This invention relates to packing inserts and more particularly to a new and improved form of an inflatable carton vpacking insert.
It has long been recognized that to safely ship and store certain articles, particularly appliances, it is necessary to package the articles in such -a manner as to virtually eliminate any movement of the article relative to its container as well as to substantially eliminate any shock which may occur due to abusive and hard, abrupt handling of the carton. One of the currently popular forms of packaging utilizes expanded foam plastic inserts having interior portions which mate with portions of the periphery of the package article and exterior portions which mate with portions of the carton which serves as theenclosure. Relatively little work has been done in the field of inflatable packaging inserts -although it has been known to provide cushioned or inflatable wall members in vehicular bodies such as trucks, railroad cars and the like.
' Whereas the expanded foam inserts fairly securely hold the packaged appliance against movement relative to the carton, shock resultant from abrupt movement of the carton is readily transmitted to the article itself. Inflatable or partially inflatable packaging means have the advantage `of absorbing some of this shock. Moreover, the expanded foam inserts require proper registration and then assembly on the appropriate exposed portions of the -article to be packed and often prior insertion into the Carton itself.
This invention is directed to the provision of an elongate member having spaced inllatable air cells constructed and arranged so that the member may be wrapped around an article, inserted in the interior of a packing carton and then air under. pressure may be applied to inflate the spaced air cells so as to securely hold the appliance or article in the carton and provide a means -for absorbing shock due to abrupt movement of the carton.
It is therefore a primary object of this invention to provide a new and improved packaging means.
It is a general object of this invention to provide a new and improved inflatable packing insert for holding and protecting an article in the interior of a shipping carton against relative movement and abrupt motion yand shock.
It is a further object of this invention to provide such an inflatable packing insert which is economical to produce, light in weight, may -be easily handled, and occupies a minimum of storage space.
Other objects, features and advantages of the present invention will be apparent from the following description of the preferred embodiments illustrated in the accompanying drawings, in which:
FIGURE 1 is an isometric view, partially in section, showing the inflatable packing sleeve of this invention ICC wrapped about an article in the interior of a packing carton; and
FIGURE 2 is a broken top plan view, partially in section, -of the inflatable packing sleeve of this invention spread out flat in a storage condition prior to use.
As shown in FIGURE l, an article to be shipped or packed, such as the appliance or television receiver 10, is positioned within Ia packing assembly 12 including a conventional box-like carton 14 of suitable material, such as heavy cardboard `or the like. Inflatable member or packing insert 16 of this invention is wrapped about the appliance 10 in a sleeve-like manner to hold the article suspended from the side 'walls of the carton, thereby protecting the article against shock and abuse normally incident to shipping and storage of such packages.
Member 16 is preferably made of a suitable plastic or other synthetic material and may be formed by superimposing two plies 16a and 16b of sheet material and heat sealing or otherwise securing the plies along the borders 17a-17d thereof. Fluid or air cells 18 are formed by sealing the plies along transverse lines 19 and along a generally longitudinal line 20 (interrupted at transverse lines 19) which provides a fluid passage 21 communicating with the several cells having an open intake end 22. Air cells 1-8 are Iarranged so as t-o be positioned adjacent the corners of the article 10` when the member 16 is wrapped about article 10, in a sleeve-like fashion, ,as shown in FIGURE l. Member 16 might also be formed from a continuous sleeve lof material, requiring sealing only at the ends 17c and 17d and along lines 19 and 20.
FIGURE l is partially broken away in section in the areas of the ends of cells 18 to show the tubular nature of the Icells and passage 21 which communicates therewith. The fluid cells are preferably formed in pairs with the two cells forming each pair separated by a small space -24 so that the Lcells 18v may be positioned on each side of a corner of an Iarticle enclosed within the member 16. The pairs of cells, in turn, are separated by relatively large spaces 26 which generally dimensionally correspond to the sides and top and bottom of the appliance being enclosed.
Member 16 may be formed in several sizes to accommodate different sized articles. Thus the width of the member 16 may differ as well as the dimension of the panels 26 between the pairs of cells. In addition, the relative dimension of the air cells and the dimension of the narrow panels 24 between each of the air cells could also differ. It is possible that an appliance 10 which is relatively undersize for member 16 which is available could still be packed therein so long as the cells 18 were :positioned adjacent the several corners of the appliance. The intermediate panel sections 26 would'have folded portions therein, but this would be of no moment except for factors of neatness which would be incidental where the appliance was to be packed within a shipping carton 14. Moreover, if the member 16 were not large enough for the article 10 with which is was to be used, two such members 16 could be used so long as they were positioned about the periphery of the article 10 in such a fashion that some of the cells 18 embraced the corners of the article.
In use, member 16 may be positioned in the interior of the carton so that one panel 26 extends across the bottom of the carton, or the sleeve may first be wrapped around an article 10 and inserted into the carton about the article. In either event, once the article is within the carton and the member wrapped thereabout, fluid, preferably air under pressure, may then be applied through intake opening 22 and fed to the several cells 18, inilating the same until such ltime as the cells 18 resist further intake of air under pressure. At this point, the cells are substantially wedged between the corners of the article 10 and the interior of the carton 14 to thereby securely hold the article within the carton. Moreover, the cells provide a cushioning effect in that the air is relatively displaceable within each of the cells responsive to the expected shock associated with shipping and storing of such cartons 14.
Once the member 16 has been wrapped around the article and inserted into the carton, the application of fluid, such as air, inflates the cells as aforedescribed. When inilation is completed, the intake 22 may be closed off by suitable means such as heat sealing, to permanently retain the fluid in the cells and form the protective packaging element as described. If desired, an inflation Valve could be provided at intake 22.
It is to be noted that fluid passage 21 is preferably formed along one edge of the member so as to normally lie outside of an appliance 10 or article about which it may be wrapped. In this manner, pinching of the passage 21 which could occur around the corners of the appliance is eliminated so that ination of the cells 18 may be accomplished after the appliance has been inserted into the carton without any obstructions in the iiuid line. Furthermore, spacing between the appliance and the inside wall of the carton which is the usual manner of packing appliances or the like provides room for the passage 21 to expand upon inflation of cells 18.
This inatable packing member lends itself very suitably to storage and use in that it may be stored in a substantially flat condition as illustrated in FIGURE 2 and yet is extremely light in weight, facilitating handling thereof. The amount of effort necessary to Wrap the member 16 about an article to be packaged requires less effort than is necessary to locate and secure expanded foam inserts in `similar packaging operations. The structure of the packaging insert itself is extremely simple consisting merely of two plies of a suitable plastic material or the like which are heat sealed in discrete areas to form the passage and cells making it economical to produce and easy to use.
The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, as some modifications may be obvious to those skilled in the art.
