COMPARTMENT AL CONTAINER.

Specification of Letters Patent.

Patented Apr. 4,1922.

Application filed March 21, 1921. Serial No. 453,871.

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had 'to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a This invention relates to compartmental envelopes adapted for use in mailing more than one class of mailing matter in a single package.

It frequently happens that it is desirable to mail a relatively heavy package of material, such as circulars, merchandise or a catalogue, and accompany the same with written instructions. Since a the, instructions generally are in the nature of a letter, the letter must eitherbe sentfseparately firstclass, or first-class postage must be applied to the package for the entire contents.

In the first instance, the package may arrive without the letter of instructions being delivered, or vice versa. It will be apparent that the ideal condition would be to have both the second, third or fourthclass matter and the letter arriv'eat the same time.

I have provided means whereby this can be accomplished without the necessity ofapplying first-class postage for the entire weight of the package.

he invention consists in providing a plurality of completel formed envelopes permanently connecte together, one of which is provided with means for completing a permanent seal, while the other co-operates with the first to provide a temporary seal.

The novel construction of the device will be apparent by reference to the accompanyvelope contained subject other than first-class matter is indicated at 1 as consisting of a relatively large, rectangular envelope, having an opening 2 adapted to be closed by a flap 3 in the usual manner. The envelope4 for thefirst-class matter is provided with an opening 5, adapted to be closed by a fiap 6 provided with an adhesive 7. The envelope 4 is adapted to be permanently attached to the fia 3 of the envelope 1 by pasting the side 8 tliereto, the length of the envelope 4 being preferably extended crosswise of the envelope 1, as shown.

The envelope 4 may have a disk or button 9 secured to the outer face thereof and a complementary fastening button or disk 10 may be secured 'to the outer face of the envelope 1 to align with the button or disk 9 when the envelope is in closing position, as shown in Fig. 1. A flexible connection or cord 11 may be fastened to one of the buttons but adapted to be wound around the other button, as'shown in Fig. 1, so that the larger envelope will be fastened.

After the envelope 4 is fastened to the flap 3 of the envelope 1 and the first-class matter inserted'in the envelope 4, the flap 7 can be folded over and sealed like any first-class vmatter is sealed. The flap 6 not only seals the envelope 4 but also seals at least one corner of the flap 3 between the body portion of the envelope 4 and its flap, so danger of its becoming detached from the flap '3 will be materially decreased. The envelope 4 then constitutes an extended flap or seal for the envelope 1, it being under- -stood that the envelope 1 is not to be permanently sealed,

but simply fastened so that access may be had for'the purpose of postal ins ection.

he envelope 4 will generally be of a different color from the envelope 1, so that the.attention of the consignee will be called to the fact that there are two "separate sets of contents. If the two compartments or envelopes were of .the same material, it couldvery-easily happen that the consignee would open the larger envelope without being aware of the fact that the smaller enmatter. If they are of different colors, however, the fact that there are two separate envelopes to'be considered will be at once apparent. There are special advantages in form ng the two envelopes separately and fastenmg them together. One important advantage I is that the envelopes can be constructed with the usual envelope machine and then assembled, whereas if they were constructed of a single blank, special machines would have to be provided. Another advantage is that less stock will be required to form the envelopes separately and then assemble them than if they were formed of. a single blank, for, obviously, a single blank would result in a considerable waste of material.

When the parts are assembled, the firstclass matter may be introduced in the envelope 4 and first-class postage applied thereto, the envelope 4 being preferably the envelope containing the address. If, however, it is desirable or necessary, the address can be put on both envelopes. The second, third or fourth-class matter may be introduced into the envelope 1, and appropriate postage applied thereto, so that the cost of sending a mixed subject matter will be con siderably less than if the entire contents were enclosed in a single package and sealed and first-class postage applied to the entire package.

- What I claim and desire to secure by Letters-Patent is:

1. A compartmental container comprising two separately formed envelopes, one of which is permanently attached to the other and one of which has a sealing means independent of the sealing means of the other, the independently sealed envelope constituting part of the closure for the second envelope, and means for fastening the two envelopes together.

2. A compartmental container comprising a relatively large envelope having a flap, a.

separate envelope having a sealing flap, the second envelope extending transversely of the first named envelope and permanently attached to its flap, and complementary fastening devices on the two envelopes.

3. A compartmental container comprising two envelopes of difierent colors, one of EUGENE BERTRAM BERKOWITZ.
