Definitions
- This invention relates to an improved package for tobacco products and the like and to a method for making the same. More particularly, the present invention relates to an improved cigarette package and method of making the same.
- the invention relates most particularly to containers which are made up of a plurality of layers of material, one of said layers bein-g a layer of material, such as aluminum foil, which is substantially impervious to the passage therethrough of water vapor and another of said layers being a librous or hydrophilic material, such las paper, which readily picks up moisture from its surrounding environment.
- paper can provide the necessary stiiness and feel for a tobacco product package, it obviously does not have the barrier properties of such materials as aluminum or tin foil.
- aluminum or tin foil alone, while providing a goo-d moisture barrier, do not have sufficient stiffness in the thicknesses which are economically feasible for packaging operations.
- a laminate or -its equivalent made of a water-impervious material, such as aluminum foil or the like, and a hydrophilic material, such as paper or the like, provides one of the most economical and most desirable materials for use in the packaging of tobacco products.
- a common type of package for tobacco products, and particularly cigarettes is a package which ismade with a laminate which comprises paper and aluminum foil held together by la suitable adhesive and coated on one or both sides, when desired, with a thermoplastic coating.
- Such laminated packages which are presently being used com- -merically in the cigarette industry, are generally folded without being heat-sealed.
- thermoplastic coating Even when such a laminated package is sealed along its edges by means of heating the thermoplastic coating to a suiicient degree to melt it and permit it to harden to form a seal along the edges of the package, they still fail to form an effective moisture barrier and commercial ,cigarette packages do not have their edges sealed.
- the major moisture barrier now in use in the tobacco ⁇ industry for packaged cigarettes is the cellophane overwrap.
- This overwrap is actually a separate package which is employed over the laminated package.
- the barrier properties of cellophane are not adequate for properly maintaining the .original moisture and oxygen in the contents of the package. Over a period of time, substantial amounts of the water vapor, oxygen and ilavorful aromatic vapors can leak through both the inner laminate package and the outer cellophane package.
- the present invention overcomes the disadvantages of the prior art and provides an improved package wherein the water vapor transmission rate (WVTR) of the pack- Iage is greatly reduced and the moisture content of the package product is substantially retained over long periods of time.
- WVTR water vapor transmission rate
- the present invention provides a package wherein the loss of volatile materials and flavors from the tobacco product are greatly reduced.
- the present invention also furnishes a means for controlling the diffusion rate of oxygen into the package whereby spoilage due to the -action of anaerobic bacteria can be prevented.
- the brous layers function as wicks to conduct moisture vapor and other vapors or gases from the inside of the package to the outside .or vice versa.
- the ibrous material provides a wicking elfect, conducting moisture either in or out of the package, even though .only the edges of the brous material are exposed to both the interior and the exterior of the package.
- an improved package element comprising a plurality of layers, including at least one librous or hydrophilic layer and at least one water-impervious layer, said plurality Aof layers being folded and joined by means of a plurality of seams to form a package having an interior atmosphere, said package having no brous layers which connect the interior atmosphere of the package element with the atmosphere which is exterior to the package element.
- the package element of the present invention can be made by folding under one surface of each seam or joining, so that there is always water vapor impervious layer-to-water vapor impervious layer contact along each seam of the package.
- the water vapor impervious layer-to-water vapor impervious layer contact may be on either the inside or the outside of the package element.
- the package element may be constructed of a plurality of distinct and unjoined layers or may be constructed of a laminate or composite of layers which are joined together by adhesives or resins and coated by waxes, resins and the like.
- the package element may -be employed in conjunction with other packaging elements, suchas a cellophane overwrap; a combination of a paper overwrap,
- the present invention is particularly applicable to cigarette packages and is equally effective with single component packs, wherein a laminate of paper and aluminum foil forms the entire wrap; with soft packs, wherein a paper wrap and a cellophane outer wrap are employed with a laminate of paper and foil; withI cardboard boxes or plastic cases containing a laminate of foil and paper, and with many other packaging applications.
- While the invention is particularly applicable tocigarette packages, it is equally effective for use in tobacco pouches and containers for other materials. It may also be employed in conjunction with outer cellophane wrappers, iptop boxes, plastic cases and the like.
- An outstanding advantage of the present invention resides in the rfact that with a few simple additional folds in the blank, a tobacco package can be made which is outstandingly superior to any package which has heretofore been made.
- conve-ntional packaging materials can be employed to much greater advantage to provide packages which result in benefits heretofore unachievable with the materials which are employed.
- the package can be opened in a conventional manner and the only distinction between the appearance and function of the present package from that of conventional cigarette packages is the fact that the ilaps are double folded to provide foil-to-foil or similar impervious surface-to-impervious surface contact at all edges and to ensure that no hydrophilic materials are exposed to both the interior and exterior of the package either on their surface or along their edges.
- a particularly preferredI form of the present invention resides in a package element for tobacco products and the like which not only prevents any significant amount of undesirable transfer of moisture vapor in or out of the package element and which prevents any significant loss of desirable flavors and aromas, but which also permits the passage of oxygen to the interior of the package element.
- an adhesive can be used intermittently along any or all seams of the package ele-ment or all but one or a portion of one of the seams may be sealed.
- Such a length of seam can be descri'bed as an adhesiveless closure.
- All other seams in the package element should have a foil-tofoil or similar contact of at least about 1/16th inch and, any seam in the package element which does not have the above-described relationship of height to length, should be sealed with a suitable hydrophobic adhesive.
- the adhesiveless closure allows the package to breathe; that is, it allows oxygen to diffuse into the pack and carbo-r1 dioxide to diffuse out of it. It is well known in the tobacco industry that anaerobic action can cause the formation of undesirable aromas within completely sealed or substantially completely sealed packages, when the interior atmosphere of the package falls below a certain oxygen content. Therefore, control of oxygen content is desirable.
- the adhesiveless closure of the present invention offers excellent protection against the loss or gain of moisture and still allows the passage of oxygen and canbon dioxide to the interior of the package.
- the length of the unsealed' seam controls the breathing and the passage through the seam has essentially zero permeability if, as set forth above, the length of the path in the direction of diffusion is greater than approximately 50 times the width of the gap.
- wickless packages of the present invention have been proven to be many times more effective in reducing moisture migration in packaged cigarettes than the standard packages overwrapped with cellophane. And the combination of a wickless package with an adhesiveless closure of :the type described above has provided even greater overall advantages.
- packages of the present invention can be employed to provide an opening for the exchange 0f oxygen and carbon dioxide between the contents of the package and the atmosphere, the exchange taking place Without any significant change in the moisture content of tobacco.
- the invention thereby provides for a package which can be stored for long periods of time without any undesirable moisture changes and without any undesirable changes due to the absence of oxygen in the package.
- the present invention overcomes a long standing problem in the art: a package which was stored for a long period of time with a barrier which was sufficient to prevent moisture loss had a resulting depletion of its oxygen content, whereby the tobacco was subject to attack by anaerobic bacteria. If, on the other hand, the package was stored for a long period of time without such a moisture barrier, in order to provide for passage through the package of oxygen, moisture would be lost or, in the event of an atmosphere that was excessively moist, the :tobacco would pick up excessive moisture, in short, the moisture content of the tobacco would be changed undesirably. Such problems are eliminated by the present preferred method land process.
- Water vapor impervious materials which may be employed in accordance with the present invention include aluminum foil, tin foil, lead foil, polyethylene, polypropylene, wax and the like. Calendered plasticized vinyl resin sheets may also be employed.
- a vinyl resin sheet can comprise polymerized vinyl chloride or copolymers of vinyl chloride with vinyl esters, vinyl acetate and vinylidene chloride. These materials may be employed as sheets or as coatings and, when employed as sheets, may be employed as lamina, adhered to other lamina by means of suitable adhesives, or may be used with other lamina without being adhered thereto.
- Fibrous or hydrophilic materials which may be employed in accordance with the present invention include such materials as paper, for example, glassine, kraft paper, sulte paper and the like, thin cardboard yand similar materials.

- Example 1 A paperlaminatedtofoil wrapper for a single-component cigarette pack was prepared by attaching aluminum foil (0.00035 inch thickness) coated continuously with polyvinyl acetate to 60-pound bond paper with a conventional adhesive (casein). The resulting wrapper or laminate was cut to the proper size to form a blank. The blank was then scored along fold lines in a manner similar to that shown in FIG. 1 that would give foil-to-foil contact and insure that no edges of the paper would be exposed to the outside when the blank is folded to form a cigarette package.
- the scored laminate was folded about the cigarettes in a manner similar to that described with regard to the drawing and each fold was heat sealed with a hand sealer heated to a temperature of about 275-300 F., whereby the polyvinyl acetate coating was melted and served to seal the folds together.
- the package was then enclosed with a cellophane overwrap. Similarly, another package was prepared with no cellophane overwrap.
- a standard soft pack (with standard folds which leave paper edges exposed) was used as a control.
- the heat sealed wickless package without a Icellophane overwrap was not as effective against moisture migration as the one with a cellophane overwrap but both of the wickless packs were significantly superior over the control as water vapor barriers.
- Example 2 was overwrapped with a printed paper label and a cellophane overwrap (a soft pack). Likewise, the 20-pound bond/foil was used as the container of cigarettes to go inside a plastic pack.
- the top fold was prepared to insure that the length of the fold would be 50 times the width of the gap when folding was completed.
- the blanks were then folded into cases and all folds, except the top folds, were heat sealed. Cigarettes were inserted, and the top was spot sealed to hold the top fold close to the package but still leave a passageway through which oxygen and carbon dioxide could diffuse. Similar packs were completely heat sealed and used as a control.
- the two packs of cigarettes were submitted for subjective evaluation of pack aroma. A difference in pack aroma was detected by the panel, and a preference for the pack aroma of the unsealed pack was expressed.
