MEANS AND METHOD 0F' PACKAGING ARTICLES Filed March 51. 1958 2,962,158 y MEANS AND METHOD or PACKAGING ARTICLES William H. Struthers, Chicago, lll., assignor to Joseph J. Klein Filed Mar. 31, 1958, Ser. No. 725,025 9 Claims. (Cl. 20d-46) This invention relates to a means and method of packaging articles, and is particularly concerned with a fibrous packaging material that may be readily sealed to protect the contents against breakage or deterioration.
The fibrous packaging materialis soft enough so that it will not scratch or mar highly polished finishes and is sufficiently resilient to protect fragile articles fromshock. The packaging material also affords eective protection against excessive heat, cold, moisture and dust.
The packaging material of the present invention comprises a soft, resilient web of thermoplastic fibrous material bonded to a suitable backing material, such as, for example, kraft paper or corrugated paper, and heat sealed along two or three edges to form a receptacle in the form of an envelope or pouch having one end open for the reception of the articles or articles to be packaged therein. The open edge of the receptacle may be closed in any suitable manner after the article or articles are inserted therein, as, for example, by stapling, or, by heat sealing.
The fibrous web comprises a mass of nonabsorbent, nonmatting fibers of various lengths from about one-half inch to two inches. I prefer acrylic fibersV (a copolymer of vinyl chloride and acrylonitrile) commerciallyavailable under the trademark Dynel.V Other thermoplastic fibers such as nylon, rayon, cellulose acetate, acrylic liber (formed from a polymer of acrylonitrile) commercially available under the trademark Or1on, fibers formed from copolymers of polyvinylidene chloride and` polyvinyl chloride commercially available vunder the trademark Saranf and the like, may be used. The fibrous web is not limited to thermoplastic fibers and may be made partially or entirely of fibers that are not thermoplastic.
The individual fibers are preferably arranged in a threedimensional random arrangement and then wetted with athermoplastic adhesive and brought into contact-with the paper backing material to bond the individual fibers to each other and to the backing material. The fibrous web is not crushed or compacted by the bonding operation and retains its softness and resilience.
The adhesive preferred is polyvinyl acetate, although other thermoplastic adhesives such as polyvinyl chloride or copolymers of polyvinyl acetate and polyvinyl chloride produce very satisfactory results. Polyvinyl acetate has `an unusually effective adhesive affinity for paper when the adhesive is heated to softening by high frequency dielectric heating, and the fibers cannot bev separated from the paper backing by ordinary handling. The adhesive is preferably applied in the form of an aqueous emulsion or suspension, but may be applied as a solution in any desired solvent.
In accordance with the invention, the fibrousweb and backing are folded along one edge so that lheat sealing is required on only two edges to provide a receptacle or pouch having one open end. It will be obvious that if the fibrous web and backing sheet are not v piped States Patent 2,962,158 v Patented Nov. 29, 1960 large enough to be folded into a pouch of the desired size, one piece of the material may be superimposed on another and heat sealed along three edges.` The articles to be packaged are inserted into the pouch and the open end is then closed, by heat sealing or by other suitable means such as stapling. If the open end of the pouch is to be stapled it may be desirable to provide a flap at the open end -to provide a more effective closure.
The structure by means of which the above and other advantages of the invention are attained will be described in detail in the following specification, taken in conjunction with the accompanying drawings, showing a preferred illustrative embodiment of lthe invention, in which:
Figure l is a perspective view of"v a sealed package embodying the invention;
Fig. 2 is a perspective view of a pouch having one end open for receiving an article to be packaged;
Fig; 3 is a plan Vview of the blank for forming` the pouch of Fig. 2; f Fig. 4 is av view similar to Fig.v 3, showing a blank adapted to be formed into a pouch having an open top; Fig. 5 is a cross sectional view, taken along the line 5-5 of Fig. 2; Fig. 6 is a perspective view of a pouch heat sealed on three edges; and f Fig. 7 is a cross sectional View, taken valong the line 7-7 of Fig. 6. Y Referring to the drawing, the reference numeral 2 indicates a fibrous web bonded to a paper backing 3. Any suitable fibers-may be used in the fibrous web, but it is preferred to use Dynel or other thermoplasticv fibers, such as Orlon, Saran, nylon, and cellulose acetate fibers. Y 'I'he fibers, ranging in length from one-half to two inches, are preferably arrangedin a three-dimensionall random arrangement in which yindividual fibers contact each other only at spaced points of contact, with a plurality of voids extending throughout the web. Generally no two fibers engage each other at more than one` point, although each fiber engages several other fibers.v The web is wetted lightly with thermoplastic adhesive which causes the fibers to adhere to each other -at the spaced points of contact to form a soft, resilient web having a high loft. Straight fibers may be used with satisfactory results, but crimped or Vcurled fibers are preferred because they provide greater loft and resilience. The fibrous web is brought into contact with the paper backing before the adhesive is set, vand the bers are bonded to each other at their spaced points of contact, and to the paper backing, without compacting the fibers, to form a continuous length of soft, resilientl packaging material. r
While any suitable thermoplastic adhesive may be used, polyvinyl acetate is preferred because of its superior adhesive affinity for paper when it is softened by heat and then set under pressure. .Other thermoplastic adhesives, such as, for example, polyvinyl. chloride, Aand copolymers .of polyvinyl acetate and polyvinyl chloride also produce very good results. Y
After the fibrous web has been bonded to the backing sheet, the packaging material is cut into blanks of the desired size. Preferably the blankshave an area approximately .twice as large as the surface area of the pouch and are folded along one edge, as indicated at 4, to form a doubled sheet of the desired size with the fibrous web on lthe inside. If desired, the composite sheet may be cut to the exact size of the .pouch and two of the cut blanks superimposed with the fibrous web on the inside, as indicated in Fig. 6.
After the packaging material is folded, or two separate blanks are superimposed, with fibrous webs in contact,
selected edge portions are heated to softening by any conventional means, preferably by electronic means using high frequency waves to provide dielectric heating, and pressure is applied to seal the fibers and the paper backing along the heated edge portions, indicated at 5. The edges to be subsequently heat sealed to form the pouch are indicated in the blanks shown in Figs. 3 and 4 by the dot and dash line 6. One edge is left open, as indicated at 7, for insertion of the articles to be packaged.
The pouches are delivered to the user in open-ended condition, and the user inserts the articles to be packaged and then` closes the open end, preferably by heat sealing. If staples are to be used for the nal closure it may be desirable to provide a tiap that can be folded over the open end to form a better closure. In such event, the packaging material is folded offfcenter, or separate blanks of different sizes are used to provide the flap.
The completed package, with an article completely enclosed withinV packaging material sealed on` all edges, provides a maximum protection against shock,A moisture, or excessive temperature. The heat sealing process fuses the paper and fibers into a unitary mass and the package cannot be opened without destruction of the pouch. A1- though the pouch is shown as having a rectangular shape, it is obvious that it may be, made of any desired shape, particularly when separate sheets of the packaging material are used. If the article to be packaged has considerable depth, a plurality of separate sheets may be fitted around the article, and the edges of each sheet may be heat sealed to the adjoining edge of an adjacent sheet.
Although I have decribed a preferred embodiment of my invention in considerable detail, it will be under-` stood that the description thereof is intended to be illustrative, rather than restrictive, as many details of the structure may be modified or changed without departing from the spirit or scope of the invention. Accordingly, I do not desireto be restricted to the exact construction described.
