thereby further assisting in preventingopening of the flanges. Between the marginal guard areas 9-H and an inner reserved area I2, perforation loops l3l6 are provided as shown. These perforation loops are disposed along axes l5 and I6 which originate at the center point oi the radius I. Axes l5 and I8 intersect the points of tangency'of the radius I with respect to the inner rectilinear boundaries of the pocket 8.

The perforation loops HI-I6 permit either corner of the package to be opened along the axes A and B. The opening of the package is accomplished by tearing through the guide margin II; at a point adjacent either of the loops l3 and I 4, the loops efiecting the controlled opening of the corner defined by the radius 1. From this corner, the contained fluid may then be exuded by application of pressure to the side walls of the pocket 8. 1

The upper flange 5 of the package is provided between folded over sheets 20 and 2| comprising a cover. A transverse interdigitated heat seal is provided within the area 22 which interlocks the flange 5 with the walls of material 20 and 2!.

The walls of material 20 and 2| have side guide areas 23 and 24 which further protect the envelope guard areas 8|| to prevent opening of the sides of the package. provided with indicia such as printed instructions and/or advertising with respect to the contained commodity.

In another arrangement of the invention, the corner tearing detail shown in Fig. 3 may be provided in the package at the upper right hand corner, and outer cover sheets 28a and 2 I a may be provided with' notches 28b and 28c with an interconnecting perforated tearing guide line in the covers 20a and Ma. In this arrangement, the corner of the entire package structure can be torn off for the opening of the package envelope structure.

In the embodiment shown in Fig. 3, a pair of fluid containing envelopes 30 and 3|, is sealed between the cover sheets 28a and 2la. These envelopes 30 and 3| are of a construction similar to the inner envelope depicted in Figs. 1 and 2. As shown in Figs. 4 and 5, the inner envelopes contain dissimilar pharmaceutical commodities adapted tobe united in use. In using such dualcontained commodities, the package structure is torn off between the notches 28b and 280 and the contents of both ,of the envelopes 38 andil may be simultaneously discharged at the corners thereof, as depicted in Fig. 6, the user exerting exudation pressure through the cover sheets 28a and 2Ia.

The sheet 8 may be- Although a preferred form'ot dispensing unit has been disclosed, it will be recognized that various changes and equivalent structures can be made without departing from the scope of the invention. Therefore, no'limitation is intended except as pointed out in the appended claims.

What is claimedas new and originalto be secured by Letters Patent 0! the United States is: 1. A fluid dispensing unit comprising layers of packaging material bonded together in a sealing flange, said flange forming a substantially rectangular inner fluid pocket with round corners 1filor distributing the stresses of the contained uid. a

2. The fluid dispensing unit in accordance with claim 1 including a weakened tearing guide-linev in said sealing flange and extending across one of rounded corners for opening the walls of said material at said rounded corner to permit of the exudation oi the contained fluid commodity.

3. A fluid dispensing unit in accordance with claim '1 including cover sheets attached to both sides of said combined layers to permit the unit as a whole to be grasped and handled by said cover sheets.

4. A fluid dispensin'gunit in accordance with claim 1 including a guard sheet structure attached to said combined layers and having the edges thereof extending beyond the edges of said flange to form an encircling protective guard margin therefor.

5. A fluid dispensing unit in accordance with claim 1 in which said sealing flange is crimped but including an outer uncrimped edge margin for guarding said sealing flange.

6. A dispensing package unit comprising, layers of packaging material sealed together to form an envelope structure having sealing flanges enclosing a commodity containing pocket structure, and a guard structure for the edges of said envelope comprising sheet material attached to said envelope and having parts projecting around the edges of said sealing flanges.

7. A dispensing package comprising, a commodity containing envelope structure having a guard cover provided with a tearing guide line extending across a corner of said cover whereby the composite package including envelope structure and cover may be torn through to open said envelope structure without completely detaching the same from said cover so that the contained commodity may be exuded through the torn opening with the envelope held through said cover.

8. The dispensing package in accordance with claim 7 in which said envelope package comprises a plurality of pockets containing dissimilar commodities adapted to be conjointly combined in exudation through said torn opening.

9. A dispensing package comprising a plurality of commodity envelopes disposed one above the other within a cover having a tearing guide extending across a portion thereof whereby said plurality of envelopes can be opened by a com- 'mon tearing operation for the discharge of a
