TEARABLE SHRINK FILM COVER INCLUDING INTEGRAL PULL TABS Filed March 4, 1964 Ronald E Sow/e 1N VENTOR.
Mm BY ym, 26m
United States Patent 3,259,235 TEARABLE SHRINK FILM COVER INCLUDING INTEGRAL PULL TABS Ronald E. Sowle, Tomah, Wis., assignor of ninety percent to Vanpak Products, Inc, a corporation of Wisconsin Filed Mar. 4, 1964, Ser. No. 349,371 16 Claims. (Cl. 206-46) This invention relates to a novel and useful tearable shrink film cover and more specifically to a film cover or enclosure for an article including integral pull tabs, the film cover or enclosure being constructed of heat shrinkable film in order that it may be shrunk into tight embracing engagement withthe article enclosed thereby when the enclosure is subjected to heat.
Shrink film covers or enclosures have been utilized for a number of years for packaging articles of irregular configuration. However, the article has heretofore been placed in an enclosure constructed of heat shrinkable film such as a bag and then the assemblage including the bag having the article disposed therein has been heated. The heat causes the heat shrinkable film to contract and to tightly embrace the article disposed therein. While this type of cover or enclosure forms an extremely satisfactory covering in most instances, it is sometimes quite difiicult to remove such a covering inasmuch as it is disposed in tight embracing engagement with the article enclosed thereby. Although a sharp instrument may be utilized to penetrate film covering and to tear the latter so that it may be gripped for pulling from the article, the use of such a sharp implement involves the danger of damaging the article disposed within the closure and is therefore not desirable.
Accordingly, it is the main object of this invention to provide a tearable shrink film cover for articles including at least one integral pull tab whereby the pull tab may be readily grasped by a person wishing to strip the cover from the article, the cover being weakened along lines defining a removable section of said cover on which said pull tab is disposed whereby the removable section may be readily parted from the cover by pulling on the pull tab in order to strip the removable section of the cover from the remainder thereof.
Another object of this invention, in accordance with the immediately preceding object, 'is to provide .a means whereby integral pull tabs may be preformed on a shrink film cover in a simple and inexpensive manner thereby maintaining the cost of the shrink film cover at a minimum.
Another object of this invention is to provide a tearable shrink film cover including pull tabs which may be constructed in a manner so as'to readily adapt the cover for enclosing substantially all shapes of articles.
A final object of this invention to be specifically enumerated herein is to provide a tearable shrink film cover including integral pull tabs which will conform to con ventional forms of manufacture, be of simple construction and easy to remove so as to provide a device that will be economically feasible, long lasting and relatively easy to handle when removing the cover from the article enclosed thereby.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
FIGURE 1 is a perspective view of an article enclosed by the tearable shrink film cover of the instant invention which includes integral pulltabs;
FIGURE 2 is an elevational view of the embodiment ice illustrated in FIGURE 1 showing the manner in which the tearable shrink film cover may be readily torn from the article disposed therein;
FIGURE 3 is an enlarged horizontal sectional view taken substantially upon a plane indicated by section line 3-3 of FIGURE 1; and
FIGURE 4 is a perspective view of the shrink film cover of the instant invention showing the manner in which it may be prepared so as to define integral pull tabs before the article to be enclosed thereby is inserted therein and the cover is heated to shrink the cover about the article enclosed thereby.
Referring now more specifically to the drawings, the numeral 10 generally designates the tearable shrink film cover of the instant invention which is illustrated in FIGURE 1 of the drawings tightly enclosing an article referred to in general by the reference numeral 12 including a pair of generally truncated cone-shaped opposite end portions 14 and 16 and a substantially cylindrical portion 18.
With attention now directed more specifically to FIG- UR-E 4 of the drawings, it may be seen that the cover 10 comprises a bag generally referred to by the reference numeral 20 constructed of heat shrinkable film. The bag 20 is open at one end as at 22 and comprises a flattened generally cylindrical member with the opposite flattened end edges of one end of the bag '20 secured together as at 24 in any convient manner such as by thermo-welding.
It will be seen from a comparison of FIGURES 1 and 4 of the drawings that when the article 12 is disposed within the bag 20 that the upper closed end of the bag will define unoccupied portions as at 26 and 28. These unoccupied portions 26 and 28 are flattened previous to the article 12 being inserted into the bag 20 and are coated with a shrink resistant coating 30 which may be of any suitable substance such as varnish, shellac or a pigmented ink which stilfens the shrinkable material and prevents it from shrinking when heated and adhering to another part of the bag 20. The coated portions of the bag 20 define opposite pull tabs 32 and 34. Before the article 12 is inserted in the bag 20, the opposite sides 36 and 38 of the bag 20 are weakened along tear lines 40 and 42, respectively. The tear lines 40 and 42 are defined by aligned longitudinally spaced short cuts formed through the opposite sides 36 and 38. After the bag 20 has been weakened along the tear lines 40 and 42, the article 12 may be inserted in the bag 20 from the open lower end 22 thereof. Thereafter, the assemblage formed by the bag 20 :and the article 12 disposed therein is heated whereupon the non-coated portions of the bag 20 will shrink into tight embracing engagement with the article 12 as illustrated in FIGURE 1 of the drawings. Then, when it is desired to remove the bag or cover 20 from the article 12, the pull tabs 32 and 34 may be grasped as illustrated in FIGURE 2 of the drawings and pulled apart whereupon the cover or bag 20 will tear along the tear lines 40 and 42 and enable the bag 20 to be readily removed from the article '12.
It is to be noted that the coating 30 may have heat conducting properties such that the heat shrinkable and Weldable film disposed therebeneath may be heated to an extent, when the assemblage defined by the bag 10 and the article 12 enclosed thereby is heated, that the inner surfaces thereof will fuse together. In this manner, the pull tabs 32 and 34 will be of stiff two-ply construction with the two-plies of each pull tab being secured together.
Although the bag 20 has been illustrated as being generally rectangular and the article 12 has been illustrated as being in the form of an irregular member thereby enabling the bag 20 to define the unoccupied areas or portions 26 and 28, it is to be understood that the bag 20 would be of irregular configuration if the article 12 were regular in shape whereby the bag 20 would still define at least one unoccupied portion which could be coated to form a pull tab. Further, it is to be understood that the cover may be in the form of a sleeve or any folded or otherwise shaped enclosure and that the pull tabs formed thereon by coating 30 will not adhere to the adjacent portions of the cover 10 as they would if they were not coated when heated.
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.
