LINER AND CURTAIN FOR CONTAINERS Original Filed June 5, .1935

INVENTOR.

Patented Oct. 31, 1939 UNITED STATES ATENT OFFICE Application June 5, 1935, Serial No. 25,014- Renewed March 27, 1939 I 2 Claims.

This invention relates to linings for containers and a method for making the same.

An object of the invention is to provide a lining for containers which has a transparent, preferably Cellophane portion, to cover the articles packed in the container; said transparent portion is so arranged on a backing sheet that the weight of the articles packed on the backing sheet holds it in place and the backing sheet thus held prevents the removal of the transparent sheet from the container until the container is emptied.

Another object of the invention is to provide a method for making a lining whereby a backing sheet and a transparent sheet, preferably a sheet of Cellophane or the like, are assembled and handled together, and the backing sheet is creased to conform to the container, without crimping or crinkling the transparent sheet.

Other objects and advantages are to provide a lining for containers that will be superior in point of simplicity, inexpensiveness of construction, positiveness of operation, and facility and convenience in use and general efliciency.

In this specification and the annexed drawing, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms; and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.

The invention is clearly illustrated in the accompanying drawing, wherein,

Fig. 1 is a plan view of a backing sheet blank, creased and perforated.

Fig. 2 is a plan view of the backing sheet with the transparent sheet on it.

Fig. 3 is a perspective view of a fruit box, the sides of the box being partly broken away, showing the lining arranged around the contents of the box.

Fig. 4 is a perspective view of a box with two complemental linings, the walls of the box being shown broken away.

In carrying out my method, I make use of a backing sheet II preferably made of opaque and comparatively thick paper or cardboard, or the like. This backing sheet II is cut to size and transversely creased at parallel spaced lines I2 and I3. The sheet I I is also perforated along said lines I2 and I3 for the purpose of ventilation. In addition of its backing sheet, this sheet II also is used to facilitate the handling of a transparent sheet I4. Another sheet I4 is preferably made of cellop a e VI I- 4 1 s a hard material to handle without crimping and crinkling. The sheet I4 is of the same. width as that of the backing sheet II, but is shorter than said backing sheet II. The sheet I4 is then superimposed on a face of the backingsh'eet II so that each of the ends I6 of the Cellophanesheet I4 is'disposed between one of the creases or fold lines I2 and the adjacent end of the backing sheet II. The ends I6 of the sheet I4 are then secured onto the backing sheet I I in said position, preferably by means of adhesive. The unit of the sheets II and I4, then can be readily put through a printing press, if so desired, for printing on the Cellophane sheet I4 a trade-mark or other indicia III. The printing is arranged in accordance with the size of linings required.

In the illustration. in Fig. 2, the marks I1 are arranged for linings of one-fourth of the size of the whole unit, but a unit may be printed for cutting transversely into two halves, if desired. Then the unit is cut either transversely in halves, or in fourths, so as to leave the Cellophane sheet I6 free excepting at the edge I6.

It is to be noted that during the printing and handling of this unit, the Cellophane sheet I4 is securely held at both ends on the backing sheet II. After the united sheets are cut to size then only the edges I6 of the sheet I4 are secured to the backing sheet II, otherwise the sheet I4 is free.

The completed lining, therefore, consists of a thicker backing sheet I I, and a superimposed thin transparent sheet, or Cellophane sheet I4.

The portion of the cut or sized backing sheet II outside of the crease or folding .line I2, forms a flap I8, and the edge I6 of the Cellophane sheet I4 is secured on this fiap- I8 near the line I2, which is the only connection between the sheets I I and I4 after a lining is cut and finished. Then by folding the flap I8 back upon the backing sheet I I, the Cellophane sheet I4 becomes a continuous and contiguous lining relatively to the sheet II.

When such lining is used in a comparatively small container such as a fruit box or basket I9, then the backing sheet II is also folded upon itself around the line I3, and the entire backing sheet thus folded forms a lining for the top layer of fruit. The Cellophane sheet I4 extends along one side of the box I9 and it is folded in an out of way position leaving both hands of the packer free for packing fruit into the box I9 over the lining sheet II. The weight of the fruit or vegetable, or other article thus packed holds the lining in place. The Cellophane lining sheet I4 being connected to the flap I8 of the backing sheet II, cannot be pulled out until the box is emptied again. After the box I9 is fully packed the Cellophane sheet I6 is folded over the top of the packed articles and provides a sanitary transparent cover at all times until the box I9 is entirely empty. The printed indicia or mark I! on the Cellophane sheet I6 is so spaced that it is located substantially in the center of the cover when extended over the articles packed.

In Fig. 4 I show a modified arrangement of my lining used in larger boxes. In this instance two complemental linings are used and the folding line I3 is so located that it corresponds to a corner 22 of the box 23. The portion of the backing sheet II between the folding lines I2 and I3 and the flap I8 folded under that portion, lie alongside the lower portion of a side of the box 23. The Cellophane sheet I4 extends in continuation of the flap I8 upwardly and forms the upper side lining and the transparent cover, as shown. Thus the bottom of the box 23 is fully covered and both half linings are held in place by the weight of the fruit, vegetables, or other articles packed thereon.

Having thus described this invention, what I claim and desire to secure by Letters Patent is:

1. A lining for a container comprising a backing sheet having folding creases parallel to the edge of said backing sheet whereby said backing sheet, when placed in a container will have the container contents resting thereon away from contact with the container, and a transparent sheet overlying the backing sheet and having an end thereof secured to the latter between an edge thereof and one of the folding creases, whereby said transparent sheet may be folded over the contents of the container resting on the backing sheet.

2. The combination with a packing container; of a backing sheet and a sheet of transparent material which has an edge thereof secured to the backing sheet along a line parallel to and spaced from an edge of the backing sheet, said backing sheet, when placed in a container having the container contents restingthereon and separated by said backing sheet from contact with the container, and said transparent sheet being foldable over the container contents resting upon the backing sheet.
