1 Claim.

This invention relates in general to packages for articles, particularly tablets, pills and the like, one object of the invention being to provide such a package'that shall embody novel and improved features of construction whereby the contents of the package shall be visible without removal from the package, the package shall be strong and durable to withstand transportation and repeated handling, and the package shall be attractive in appearance.

Another object is to provide a package of this character that shall be pilfer-proof, that is, shall embody novel and improved features of construction whereby unauthorized removal of the contents of the package without breaking of the package shall be prevented.

Further objects are to provide a package of this character that shall be in the form of an envelope and shall have a novel and improved construction including a pocket having a transparent wall and a cover flap to protect said transparent wall against injury and at the same time close said pocket; and to provide such a package wherein the cover flap may be flexed by 5 simple pressure on the package to expose the conparent wall, but at the same time access to the contents shall be prevented to ensure against unauthorized removal thereof.

Other objects are to provide an envelope package which shall include a pocket having a transparent wall and novel and improved means for producing a frame around said transparent wall and protecting the edges of the wall against injury during handling of the package, and to obtain other advantages and results as will be brought out by the following description when read in conjunction with the accompanying drawing in which Figure 1 is a top plan view of the envelope 40 package embodying my invention, showing the cover flap opened to expose the pocket.

Figure 2 is a perspective view of the package from the front showing it closed and sealed.

Figure 3 is a similar view of the package from the bottom.

Figure 4 is'a transverse vertical sectional view on an enlarged scale taken on the line 4-4 of Figure 2.

50 Figure 5 is a vertical longitudinal sectional view taken on the line 5-4 of Figure 2, and

Figure 6 is a plan view of the auxiliary package for the articles to be packed.

Specifically describing the invention, the pack- 55 age is shown as including a single sheet A of suittents of the package to view through the trans-' I tion 3 that are integrally hingedly connected to- 5 gether and are of approximately the same size and shape.

An article receiving pocket B is carried by the back section 2 and comprises narrow flanges I, 5 and 6 integral with and extending along the free f edge portions of the back section 2. These flanges are folded inwardly over the main portion of the back section and are secured to the corresponding edges of a sheet I of transparent material, such as Cellophane or Pliofllm to form a transparent front wall for the pocket B. The sheet I is approximately coextensive with the main portion of the back section 2, and has its other edge 8 free from or unconnected with the main sheet A and disposed along the line of fold or hinging l between the back section and front section to. form an bpening for the pocket B.

Preferably the sheet I is thermoplastic or has a thermoplastic coating, and is secured to and beneath the flanges l, 5 and 6 by application simultaneously of heat and pressure to the flanges and the corresponding edge portions of the sheet I. The flanges and edge portions of the sheet 1 also preferably are corrugated'or crimped so as to form a crimp-seal and reenforce and stiflen the flanges and the corresponding edges of the transparent sheet In use of the package, the articlesto be packed are slipped into the pocket through the open edge 8 as shown in Figure 1, the articles being illustrated as circular tablets C. The cover section 3 then is folded over the transparent front wall pocket and preferably sealed to the back section 2 as by an adhesive sealing strip 8. The

cover section 3 thus protects the transparent wall I from injury and also-closes the opening 8 of the pocket as clearly shown in Figure 4. -When it is desired to view the contents of the package without breaking the seal 9, the package may be compressed edgewise in the hand as shown in Figure 4 so as to flex the cover section 3 as indicated by dot and dash lines and permit the contents of the package to be viewed through the end of the package between the flexed cover section and the transparent wall I. The transparent 5 wall and flanges 4, 5 and 6 prevent pilfering of the contents of the package without breaking of the seaL, The flanges 4, i and 6 reenforce the edges of the pocket against damage at all times, and due to their overlying relation to the edge portions of the transparent sheet 'I and the crimping of the flanges and said edge portions, the possibility of the transparent wall accidentally being torn away from the flange is reduced to the minimum. I

To open the package it is necessary simply to break the seal '9 and unfold the cover section 3 as shown in Figure 1, whereupon access to the pocket is afforded through the opening 8 for removalfof the articles C. In this condition of the package the flanges I, I and 8 form an effectual and attractive frame for the articles, and the quantity of contents of the pocket is clearly visible'without removing the contents from the pocket.

Preferably the articles, especially where they are pharmaceutical tablets, will be placed in an auxiliary package as shown in the drawing especially Figures 4, 5 and 6. The auxiliary package D includes a strip of transparent material such as Cellophane" or Pliofllm folded upon itself with the article C between the layers of the folds and with the layers sealed around the articles as indicated at E.

To afford a view of the nature of the contents of the package at all times, the back section 2 may have a perforation or window ID, the auxiliary package D preventing loss of the contents of the package through said perforation.

Having thus described my invention, what I claim is:

An envelope package including a single rectangular piece of opaque material folded longitudinally to provide a front section and a back section integrally hingedly connected and is: approximately the same size and shape, the back section having an integral narrow flange at each of its three edges folded inwardly over the section, and a wall of transparent flexible material permanently crimp-sealed along three of its edges to and beneath the respective said flanges to form a pocket between itself and said section, the other edge of said transparent wall being free and approximately coincident with said fold between said sections to provide an opening for said pocket along said fold, whereby said flanges form a frame for said transparent wall and protect and reenforce the edges thereof, said wall prevents unfolding of said flanges, and the front section may fold over and overlie said transparent wall to protect the latter from injury and to close the opening of said pocket.
