PATENTED mas I970 A TTO/PA/f su'r WRAPPER FOR PRODUCE FIELD OF THE INVENTION This invention relates generally to thin, flexible plastic wrappers for produce and the like, fonned with patterns of slits which are capable of opening up for entry of air and moisture, and to permit the wrapper to conform to the article to be wrapped.
BACKGROUND OF THE INVENTION U.S. Pat. No. 3,040,968 shows, in FIGS. 1-5, the original produce wrapper of the class under consideration. It is shown in said patent to be used in connection with abasket. It is now in wide commercial use for packaging of heads of lettuce without the basket, being simply tied about the produce in the manner represented in FIG. 3 of the patent. This article has proved so desirable and advantageous that approximately 90 percent of the lettuce now being marketed in Southern California is packaged in slit wrappers of the type shown in FIGS. 1-5 of said patent, while use of this wrapper is spreading nationally and has extended into Canada.
A purpose of the present invention is to provide an improved wrapper of this class, with joint objectives of improved conformity to'the shapes of heads of lettuce, and the like, savings of material, and other advantages to be mentioned.
Also, a part of the prior art is a diamond-shaped, thin plastic sheet formed with a pattern of slits which run parallel with the long diagonal of the FIG. These slits enable the sheet to be stretched laterally to fit it to the top of a square basked. See U.S. Pat. No. 3,109,579. The slits of this article run in the wrong direction to give the effects sought by the present invention.
BRIEF SUMMARY OF THE INVENTION toward the ends, i.e., toward the acute angle points" of the sheet. The spaces between slits preferably are made longer toward these points. Accordingly, a bag formed by bringing the two acute angle points togethen'or across one another, about such an article as a head of lettuce becomes more baggy or pouchy, in the central area than at the ends, owing to the wider openings made possible by the longer slits. The wrapper in this unique form is of material advantage over that of the original patent in that it automatically shapes itself better to a head of lettuce, or the like. A wrapper of lesser square inches of stock may be used for a head of lettuce of a given size when compared with the previously known wrapper.
DESCRIPTION OF THE DRAWINGS Reference is now directed to-the drawing showing one illustrative embodiment of the invention, and wherein:
FIG. I is a perspective view of a wrap, illustrative primarily of the initial position thereof at the beginning of the wrapping of a head of lettuce, the details-of the slit arrangements not being shown excepting in a conventionalized way in this FIG.;
FIG. 2 is a perspective view of the wrap showing, in full lines, and in phantom lines, further successive stages in the wrapping of a head of lettuce with the wrapper of the present invention;
FIG. 3 shows the wrap completely about a head of lettuce;
FIG. 4 is a plan view showing a number of the wrappers in accordance with the invention joined initially edge to edge by line of perforations and illustrating a convenient way in which the invention may be marketed to the public; and
FIG. 5 is a plan view of a wrapper in accordance with the invention, showing a typical pattern of slits as provided by the invention.
DESCRIPTION OF A PREFERRED EMBODIMENT The produce wrapper W of the invention comprises a generally diamond-shaped sheet or film of thin, highly pliable material, such as transparent polyethylene plastic. The wrapper is, as stated, generally diamond-shaped, or in the shape of a parallelogram, with nearly or approximately equal sides, and-has a central slit area S. Preferably, for best proportioning, I make the upper and lower edges 11 and 12 equal to the perpendicular distance between these edges, and for packaging of good, average-sized heads of lettuce, this distance may advantageously be approximately 1 1". For smaller heads, the dimension may be reduced to 10%".The II dimension sheet contains 132 square inches of stock, in comparison to square inches formerly in the square design for an equal sized head of lettuce. At the same time, the new shape, of reduced area of material, does a better job in ways which will be pointed out hereinafter. I
The central area S is formed with parallel rows of slits 13, these rows being transversely spaced'by a distance preferably of substantially three-sixteenth inch, and being oriented substantially perpendicular to the long'diagonal of the parallelogram.
The end areas E adjacent the points 13a of the parallelogram, i.e., the tails, are utilized primarily as ties, and are hence preferably unslit for strength. Actually, the dimension of the slit area S measured parallel to the long diagonal of the sheet is preferably substantially one-halfthe length of said diagonal, leaving an unslit length of tie or tail E at each end equal to about one-quarter the length of the long diagonal.
The slit area S is otherwise formed with solid border areas 14 and 15 of proportions as illustrated in FIG. 5.
Examining the slits more in detail, it will be seen, particularly from FIG. 5, that the slits 13 in alternate rows are placed approximately in transverse alignment, while the slits 13in adjacent rows are offset in the lengthwise directions of the rows. It is only necessary that the slits of alternate rows be approximately in transverse alignment, and FIG. 5 shows a pattern illustrating considerable freedom in this regard. In other words, slits of alternate rows must be, for the most part, or for the predominant part of their lengths, in transverse alignment with the larger parts, or predominant parts, of the slits in the rows which are one row removed. The slits. in the row intervening between the alternate rows are then to be substantially offset from the slits of the alternate rows, so as to provide spaces 16 between successive slits of a row which are transversely aligned with intermediate portions of slits of the next adjacent alternate rows. It will be seen that these conditions are necessary for the sheet to open up,'when stretched, substantially in the manner of so-called expanded metal.
In consonance with these conditions, rows of substantially transversely aligned slits may be traced across the slit pattern of FIG. 5, for example, but these rows are of a meandering character, rather than straight. One such row is outlined in dot-dash lines in FIG. 5. Moreover, according to the invention, the rows in the most central region Sc of the area S are longer than the slits in the end'areas Se thereof. In the illustrative example, the slits in the central area Sc are l" long, and are spaced end to end by V2", while in the end areas Se, the slits become gradually shorter, while the spaces between slits grow gradually longer. This feature contributes to strength of the article towards the ends, where additional stresses and strains are produced, owing to tying, than in the baggy middle.
The wrappers may be produced in long strips, with perforate lines 20 in between to permit easy separation, as seen in FIG. 4.
FIG. 1 shows the wrapper in perspective, just prior to wrapping a head of lettuce therein. In this view, no great effort has been made to show the pattern of slits accurately, an actual representative pattern in accordance with the invention having been shown in FIG. 5. FIG. 2 shows a head of lettuce 22 resting on the central area of the wrapper, and showing how, if the tails, or ties E are held, and the weight of the lettuce caused to bear down on the wrapper, the slits will open up and form a large pouch 24. It will be understood readily that the slits in the central region of the wrapper being longest, the central area of the wrapper will "open up greatest, the direction of stretch being of course transversely of the slits, or in other words, parallel with the long diagonal of the wrapper. To complete the wrap, the ends, "tails," or ties" E are brought up, as represented in phantom lines in FIG. 2, and then crossed and tied in a knot 26, as represented in FIG. 3.
The resulting wrap is snug and neat, and the wrapper conforms nicely to heads of different sizes, the slits opening up more or less to accommodate to differentialized or shaped heads. The long slits in the central region open up wide where large expansion is required, and the progressively shorter slits at the ends open up progressively less, as best fitted for neatness of wrap. The slits become shorter and the spaces between slits become longer toward the ends of the wrapper so that these end regions of the slit area are of maximized strength and less apt to tear owing to the strain of typing. Thinner guage material is thereby possible. The tails" are proportionately longer and narrower than in the case of the older square wrap, and tying is facilitated. The long, central area slits, where undue strain does not occur, does not harmfully weaken the wrapper, and does afford more open area, and therefore better exposes the lettuce when sprinkled for freshness.
The invention has a highly unique advantage, in that, despite economizing on material, the wrapper forms a proportionately larger pouch, and accommodates a proportionately larger head of lettuce.
