More particularly, the invention relates to such garment-containing bags which are constructed in such a manner as to provide a strengthened and permanent protective cover for such garments.
The use of transparent plastic bags for the protection of garments and other such articles has become a widely utilized technique. These bags are now most conveniently supplied in roll form in a continuous series from which the individual bags can be successively detached for easy use. One particular method which has proved eminently successful is a method according to which a garment is suspended in vertical disposition and the foremost bag of a series drawn down over the same and subsequently detached. An example of such a bagging procedure is contained in U.S. Pat. No. 3,181,773 to Jelling et al.
For reasons of economy as well as ease of storage and use, these bags are generally fabricated of a pliable plastic material such as polyethylene. Further, to provide that such bags adapt readily to the shapes of the articles to be covered, and also for reasons of economy and to minimize their weight, these bags are generally fabricated with a minimum wall thickness.
The use of such bags with very small wall thicknesses, and made of a pliable plastic material wherein a garment, generally disposed on a hanger the neck of which protrudes through an opening in the upper portion of the bag has, however, not been entirely satisfactory. That is, the pressure applied upon the upper portion of the closed bag has caused the top of the bag, however sealed, to tear, therefore causing the bags to fall off of the garments. A typical example of the construction of these prior known garment bags is contained in U.S. Pat. No. 3,007,567 to S. Rosen.
To overcome these problems, the present invention contemplates the provision of a highly improved bag, which is prepared in such a manner, and sealed in a highly specific manner at the top thereof, such that a seal of greatly improved strength is maintained, and further such that the pressure applied to the upper portion of the bag is dispersed along its surface, and a bag of highly improved quality is obtained.
It is thus the principal object of the present invention to provide a garment bag which is simple in construction, easy to use, effective in its protection, and is of substantially a non-tearable nature in its normal usage.
It is a further object of the present invention to provide a garment bag which is sealed at the top, and which is of a strength by which the seal can be maintained under extreme stress.
It is a further object of the present invention to provide a garment bag which is advantageously made of tubular sheets of transparent synthetic plastic materials, and is provided with heat-sealed seams.
Other objects and advantageous features of the present invention will be apparent from the description and claims.
The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part thereof, in which:
FIG. 1 is a view in perspective of the garment containing bag in accordance with the invention;
FIG. 2 is a front elevational view of the garmentcontaining bag of FIG. 1; and
FIG. 3 is a horizontal or transverse sectional view of the bags shown in FIGS. 1 and 2.
It should, of course, be understood that the description and drawings herein are illustrative only, and that various modifications and changes can be made in the structure disclosed without departing from the spirit of the invention.
Like numerals refer to like parts throughout the several views.
The garment-containing bags in accordance with the present invention can be made of any desired material, but it is preferred to employ a tubular sheet of a transparent synthetic material which is inert, flexible but relatively inelastic, and which can be heat sealed or seamed. A particularly suitable material is polyethylene in film form of a thickness and range from about 0.0005 millimeters to about 0.003 millimeters. Polypropylene of similar thicknesses may also be employed.
Referring now specifically to the drawings, the numeral 3 generally designates the garment bag of the present invention, which for purposes of description will be described as having an upper portion generally designated by the numeral 15 and a lower portion generally designated by the numeral 16, and in addition although the bag will generally be formed from a continuous tubular sheet, it will normally be flattened, as when contained on a roller, and will have a front face 13 and a rear face 12 (see FIG. 3), again for purposes of ease of description. The garment bag will be of generally conventional construction as described herein. That is, the garment bag 3 may be constructed of poly propylene or polyethylene and may be of conventional size for receiving garments such as a suit, trousers, etc. or other garments normally disposed in a garment bag and supported from a garment hanger 11 having a supporting hook 10 extending upwardly therefrom and normally received within an opening, 7, disposed in the center of the upper portion 15 of the garment bag 3, i.e., where the front and rear faces, 13 and 12, respectively, converge.
Each garment bag 3 is a section of a roll of such bags 1 disposed on a roller 2 from which a continuous supply of such bags may be withdrawn. Each such bag is thus delineated by a plurality of equi-distantly spaced transverse lines 4 of perforations which constitute tear lines and divide the roll of garment bags into a sequence of separable sections or bags having, as noted, upper and lower portions 15 and 16, and front and rear faces 13 and 12, respectively. The method of forming and the arrangement of the perforations are known to those skilled in the art and require no more explanation in this text.
In accordance with a preferred embodiment of the present invention, cross seams 5 are provided in order to provide a seal between the front and rear portions, 13 and 12, of the garment bag 3, at the upper portion 15 thereof. These scams 5, which are interrupted at the center to provide an unsealed portion, or opening 7, through which the supporting hook 10 of the garment hanger 11 may extend, form the single most significant aspect of the instant invention. It has thus been discov ered that these seams 5 may be disposed upon the garment bag 3 in a manner such that a significant strengthening of the seam maintained between the front and rear portions, 13 and 12, of the garment bag 3 may be provided.
Said cross seams 5 are disposed in angular disposition to the transverse performations 4, and are provided with a curvature 21 at the upper portion thereof concave to the opposing cross seam, and to the opening, 7, therebetween. Said curvature at the upper portions of said cross seams 5 is preferably circular in nature, having a radius 6 of between about 1 inch and 4 inches, and preferably between 2 inches to 2.5 inches, so as to conform to the neck portion of the garment adjacent to the opening 7.
The seams, 5, which are preferably heat sealed, consist of at least one continuous seal but preferably two parallel continuous seals disposed on the surface of the upper portion of the garment bag 3 so as to seal the front and rear faces thereof, 13 and 12 respectively, together, thus closing the upper portion, 15, of the garment bag, except for the opening 7, which remains between the curved faces of the cross seams 5. The parallel sets of seals are made continous by a seal, preferably circular, connecting the parallel seals at the curved upper end thereof. These sealed cross seams will preferably be disposed at an angle 9 to the transverse performations 4 of between 1 10 and 146, preferably between 1 16 and 126, i.e., such that the angle between the sealed cross seams, 5, and the transverse perforations, 4, will be between 17 and 35, preferably 27 to 32, dependent on the type and shape of hanger to be utilized. Additionally, the use of a cross seam comprising a continuous double seal as described herein, which is completed by an angular seal at the upper portion thereof, allows for the provision ofa set-back 8 of from 0.5 to 1 inch, preferably 0.625 to 0.75 inches between the completions of the seals and the transverse perforations, 4. V
It is also within the scope of the present invention to provide seals, 5, consisting of individual perforations formed in substantially the same shape as described above with respect to the heat sealed cross seams, 5. it is essential, however, that the curved portion 21 terminate at a point 22 which is spaced a distance from a line extending from the end of the main shoulder portion 23 of the cross seams 5.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed. 5
