Claims. (Cl. 229—51)

This invention, relates to packages and the object is to provide a wrapped package which will afford protection for the contents from deterioration due to access of air or moisture thereg to and yet will be of attractive outward appearance and may be easily opened to dispense the contents.

My invention will be well understood by reference to the following description of the illusjq trative embodiment thereof shown by way of example in the accompanying drawing, wherein:

Fig. 1 is a perspective of a complete package;

Fig. 2 is a plan of an inner wrapping sheet as viewed from what in use is the inner face j5 thereof;

Fig. 3 is a plan of an outer wrapping sheet;

Fig. 4 shows the inner wrapping applied;

Fig. 5 illustrates the beginning of the wrapping operation utilizing the outer wrapping; and

Fig. 6 illustrates the package with the wrapping partly torn away to expose the contents.

In Fig. 11 show a chewing gum package having a wrapping 8 which encircles the same and has its end portions folded over in the form of super„ posed flaps at 10 in the customary manner, the ⁸⁰ terminal overlying portion of the wrapper being provided with a slightly projecting tab 12 designed to be grasped by the fingers to initiate a tear, illustrated in Fig. 6, which will remove „0 a zone of the wrapping which lies between the ends of the package to expose the enclosed commodity, such as the individually wrapped sticks of gum 14, and leave the folded end portions in position as cap-like members which may be __ readily stripped off.

⁰⁰ Packages as described in the preceding paragraph, utilizing a single wrapping sheet of a length to encircle the commodity and lap on itself, are well known but their use is limited since either the package is not effectively sealed ⁴⁰ to resist deterioration of the contents or the means necessary for effective sealing adversely affect its appearance and consequently its salability. Thus we might suppose the wrapper 8 ._ to be of transparent cellulose, commonly known ⁴⁸ as Cellophane, printed in reverse on the back or inner side thereof in simulation of the enclosed paper wrapper. Such a wrapper might be sealed in a sense by a suitable heat-sensitive ₅₀ adhesive applied at the longitudinal joint and at the interfolded ends, but such “sealing” would be effective to hold the wrapper in position but would not be air-tight. Reliably to obtain an air-tight package some sealing medium should _M be used, paraffin wax being suitable, which will flow to fill the spaces between the overlying portions of the wrapping, and the adhesive then might appear at the exterior at the joints or spread to adjacent parts thereof and spoil its appearance. 5:

In accordance with my invention I provide an inner wrapping providing an air-tight enclosure and an outer wrapper providing an attractive external covering, the two being so related that they may be torn off the commodity by a sub- jq stantially single continuous operation.

In Fig. 2 I illustrate an inner wrapper sheet 16 of suitable impervious material, as, for example, metal foil, and having a main portion of a size to encircle the commodity and fold over 15 the ends and having also a narrow terminal flap 18 of no greater width than the length of the commodity for purposes which will be decribed. Margins of the body portion of this wrapping sheet may carry on its outer face a ₂θ suitable flowing adhesive 20, as paraffin wax, while the inner face of the flap 18 may be provided with a stripe 22 of suitable heat-sensitive adhesive. The commodity is placed on the nearer face of the wrapping sheet 16, viewing Fig. 2, „ and wrapped in the usual manner, the lowermost margin, as shown in Fig. 2, being the inner end of the encircling wrapper. The adhesive 20 is caused to seal the longitudinal joint and the interfolded ends, penetrating all the joints of ₃θ the enclosure to form a completely sealed covering, as shown in Fig. 4, from which projects the flap 18.

The outer wrapping sheet 8 in Fig. 3 of suitable attractive character herein has its inner terminal portion attached to the flap 18, prefer- ³⁶ably by inserting it beneath the same, as indicated in Fig. 5, the flap 18 then being folded down as indicated by the arrow at the right and secured to the outer face of the wrapper 8 by the adhesive 22. The outer wrapping is then ⁴⁰folded about the commodity as indicated by the arrow at the left in Fig. 5 and secured by suitable adhesive, for example, at the folded-over ends 10. The preferable arrangement is such « that the flap 18, interleaved with the turns of * the outer wrapper, underlies the outermost terminal portion thereof with its distal edge substantially coinciding with the terminal edge of the outer wrapping at the tab 12. 55

When the projecting tab 12 is seized, the central portions of both wrappers may be torn away as a single operation to free the contents. Such tearing operation is shown partly effected in Fig. 6. The torn edges appear as rough lines in that

2,201,956 figure. The tears start at the ends of the tab ί 2 and, particularly if the grain of the paper extends circumferentially of the package as would normally be the case, are propagated sufficiently d straight to sever the wrapping into three parts.

It will be noted that the commodity is received within a completely sealed protecting enclosure provided by the inner wrapper IS, yet has an attractive covering formed by the outer wrapper 8 10 which completely covers the inner wrapper 16. The sealing of the inner wrapper is effected without possibility of damage to the external wrapper, and any irregularity in appearance arising from the sealing operation is effectually concealed by 15 the outer wrapper.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be 20 considered in all respects as illustrative and not restrictive; reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
