'8 Claims.

This invention relates to containers or envelopes of the display type having certain economical features which will appeal to the trade, an object being to present certain novel features of construction with consequent cuts in cost of production.

Many grades of paper, appropriate for constructing display containers, are far cheaper than Cellophane" well known as tough transparent sheet material now generally used as the window side of hermetically sealed dust-proof containers for flat or substantially flat piles, stacks or folded articles of manufacture.

The principal feature of this invention is making or forming containers having the above characteristics, in which a main or base sheet of paper cut with .a base portion and an extended 'p or cover portion of the same width, folded back onto the base portion at a point to determine the size or area of the package desired. This flap or cover portion may be of such size as to extend over the base portion from about A to about of its dimension, so that a primary pocket portion is formed by the opaque base sheet and its extension and a secondary pocket portion covered by a sheet of Cellophane is formed for the content of the container, said sheet of Cellophane being cut to a size equal in width to the base paper portion, plus about half inch 80 in the direction of the flap; this half inch extension of the "Cellophane is intended to underlie the inner edge of the flap and be sealed thereto in the general single movement for sealing the three side edges of the-container over the con- 85 tents of the package, thus one edge of the container is self-sealed by the turned back paper flap.

Of course, the inner edge of the Cellophane may be sealed to the upper or outer edge surface of the flap if desired and the overlapped sealed joint may be but 54; of an inch more or less if found sumcient for creating an air-tight unionof stability.

With the above construction the buyer by grasping the double or two ply paper side of the container from V to more than of the content may be inspected through the transparent window, which in practice, is quite satisfactory, and this two-ply paper construction serves also to stiifen or reinforce that side of the package far better than would a superposed sheet of paper not directly a portion of the base paper sheet,

for gripping or handling the package, without 65 damage to its contents.

In the drawing showing a preferred form of the invention,

Fig. 1 is a front or face view of the improved container and disclosing diagrammatically, its content; I

Fig. 2 is a vertical section of the container as shown in Fig. 1, the line of section being indicated by the broken line 2-2'thereon;

Fig. 3 is a cross-section through the container on the broken line 3-3 of Fig. 1;

Fig. 4 is a similar view, but taken on the broken line 4-4 of Fig. 1; Fig. 5 is a fragmentary section of the lower part of the container as here disclosed,.showing the connection between the flap and the transparent sheet as a slip or unsealed joint;

Fig. 6 is a fragmentary face view and shows a separate sheet of paper as a substitute for the flap which is sealed to the transparent sheet and three edges of the base sheet;

Fig. 7 is a detail section on the line -'l--l of Fig. 6; and

Fig. 8 is a similar detail section of a form of construction in which the bottom and sides of the separate sheet of paper is sealed to three edges of the base sheet but having an unsealed or slip joint with the transparent paper sheet above described.

Referring to the drawing indetafl, l0 designates the container, comprising a relatively heavy orv stifl' opaque base-sheet II, which is extended in one direction for providing a flap l2 to be turned back over a portion of the content, as at I2a.

The base sheet H, and its flap portion I2, collectively form a partial pocket l3, (see Fig. 2)

while the remainder of the pocket is formed by a sheet ll of transparent paper, which is secured at three' of its edges as at IE, to three corresponding edges of the base sheet II, by glue or otherwise, and by its fourth or inner edge IE, to the inner edge ll of the flap l3, by glue or otherwise, thus completing the container pocket l3 for enveloping its content I8, shown here as fancy paper doilies, but of course, the utility of the invention extends to all flat goods Where air and dust-proof packing for protecting goods of a delicate nature against shop-wear and damage are used.

In Fig. 4 of the drawing, the sides IQ of the -flap l4, are shown as directly sealed at 20 to the base sheet ll, thus a. complete pocket is formed of connected opaque and transparent sheets and proportioned so that a prospective customer may gain full knowledge of the content with respect to lace designs, colors etc. disposed within the package and from the observations the selections may be made. I

In Fig. 5 the joint between the flap it and transparent sheet is maybe left unsealed in a slip joint 2i.

In Fig. 6, a form is proposed, in which a sep-, arate sheet 22 of substantial or still opaque paper is substituted for the flap if, and is sealed to the transparent sheet it at It, and to the sides and an end of the base sheet II, as at It, and".

Fig. "I better shows the sealed Joint II forming a union between the separate piece of paper if and the base sheet ll.

Fig. 8 discloses another proposed form in which the separate sheet 22, has a looseor sliding connection II with the transparent sheet it.

The flap portion if performs'three functions:

-1st, its overlapped attachment to theside edges produces a stiffened reinforced area to be by the inspector; 2nd the bend Ila forms a blind seal at one side of the container and 3rd, and most important, is the savingof much "Cellophane material on each container, since it has only to extend over the side seams and over the contents to underlap the inner edge of the flap portion if to which it may be sealed, so that in a run of say five thousand containers through the assembling machine a great saving in "Cellophane is achieved.

Having thus described our invention what we claim is:

l. A container comprising a base sheet of substantial heavy paper having a length somewhat greater than its width, the excess material in the length of the base sheet being folded back to form a single blind sealing edge of a pocket and a single flap extending over the base sheet; a transparent sheet of material arranged over the base sheet and having a major edge portion thereofsealedtothebasesheetinfaoetofacerelation and a minor edge portion sealed to a free edge of said flap and the remaining free edges ofsaidflapbeingsealedtothesideedgesofthe base sheet in face to face relation to complete the sealed pocket. y

2. A container comprising a base sheet of the proper width but longer than a desired package, the excess length of base sheet material being sharply folded over the contents and base sheet: a transparent sheet of material coinciding in width to the width of the base sheet and having a length extending from the'free'end of the base and extending from the bottom edge thereof, said strip overlying a substantial portion of said base sheet and having its side edges connected in face to face relation to like edgeportions of said base sheet, a sheet of transparent material having a width co-extensive with that of said base sheet and having its top and side edges connected to like edge portions of said base sheet in face to face relation thereto. and the lower edge of said transparent sheet slightly overlapping the upper edge of said strip.

4. A container for flat articles comprising an opaque base sheet, a strip of opaque material extending from the bottom edge of said base to of said base and having its top and side edges connected to like edges of said base in face to face relation thereto, the lower edge of said transparent sheet slightly overlapping the upper edge of said strip, and at least'the top and side edges of said transparent sheet and said strip terminating at like edges of said base sheet.

5. A container comprising a base sheet, a single portion thereof being adapted to be folded back upon itself to overlie a substantial portion of said base sheet, the side edges of said portion terminating at like-edge portions of said base sheet and being attached thereto in face to face relation, a transparent sheet overlying the remainder of said base. sheet, one edge of said transparent sheet having a slightly overlapping relation with thefree edge of said folded portion, the remaining edges of said transparent sheet terminating at like edge portions of said base sheet and being attached thereto in face to face relation. 5

8., The structure of claim 5,and the overlap ping edegs of said transparent sheet and saidfoided portion being Joined together in face to tainer contents, and a flat flexible transparent member overlying the remainder of said base and contents, the lower edge of said transparentmemher having a slightly overlapping relation with the free edge of said pocket, and the side and top edges of said transparent member being attached to like edge portions of said base in face to face relation.

8. The structure of claim '1, and the overlapping edges of said transparent member and said pocket being attached together.
