Abstract

An envelope package including a plurality of generally aligned envelopes, the plurality of envelopes being compressed together. The package further includes a generally non-elastic band extending around the plurality of compressed envelopes and retaining the envelopes in a state of compression. The plurality of envelopes exert an expansion force of at least about ½ pound such that the plurality of envelopes are sufficiently compressed to generally seal ambient air out of the plurality of envelopes to thereby reduce absorption of moisture and warpage thereof.

Claims

1. An envelope package comprising:

a plurality of generally aligned envelopes, said plurality of envelopes being compressed together, the plurality of envelopes including at least 50 envelopes; and

two or more generally non-elastic bands extending around said plurality of compressed envelopes and retaining said envelopes in a state of compression, and wherein said plurality of envelopes, due to the state of compression thereof, exerts an expansion force of at least about ½

pound such that said plurality of envelopes are sufficiently compressed to generally seal ambient air out of said plurality of envelopes and to reduce absorption of moisture therein, further wherein each envelope is generally flat and planar in the absence of outside forces, and wherein said bands retain said plurality of envelopes in a limited state of compression such that none of the banded envelopes are bowed out of plane by more than about 1/40 of the length of that envelope.

2. The envelope package of claim 1 wherein said bands retain said plurality of envelopes in a state of compression such that said plurality of envelopes are compressed at least about 10% from their uncompressed state.

3. The envelope package of claim 1 wherein each envelope includes a cavity having a throat and a flap which can selectively cover said throat.

4. The envelope package of claim 3 wherein each flap includes an adhesive located thereon such that each flap can be adhered to a body of an associated envelope to thereby seal the associated envelope.

5. The envelope package of claim 1 wherein each envelope is generally rectangular in front view and has a plurality of outer edges, and wherein the outer edges of each envelope are generally aligned such that said plurality of envelopes form a generally rectangular prism.

6. The envelope package of claim 1 wherein each envelope is generally flat and planar in the absence of outside forces, and wherein said plurality of envelopes are compressed in a direction generally perpendicular to said plane of each envelope.

7. The envelope package of claim 1 wherein at least one said band is made of a generally air-impermeable material.

8. The envelope package of claim 1 wherein at least one said band has a width of at least about 1 inch.

9. The envelope package of claim 1 wherein at least one said band extends around the center of said plurality of envelopes.

10. The envelope package of claim 1 wherein at least one said band includes a marking thereon.

11. The envelope package of claim 10 wherein said marking is located a predetermined distance from a side edge of said plurality of banded envelopes such that the marking is utilizable by a vision-guided robot or an optical recognition machine to determine at least one of the location of the side edge of said plurality of banded envelopes and the orientation for processing of said plurality of banded envelopes.

12. The envelope package of claim 1 including a third band extending around the plurality of envelopes and spaced apart from at least one other band such that said third band helps to retain said plurality of envelopes in a state of compression.

13. The envelope package of claim 1 wherein each envelope is generally flat and rectangular in front view and includes four outer edges, and wherein said band extends only around two of said outer edges of inner ones of said envelopes such that said inner ones of said envelopes each have two unbanded edges.

14. An envelope package including:

a plurality of generally aligned envelopes, said plurality of envelopes being compressed together; and

two or more generally non-elastic bands extending around said plurality of compressed envelopes and retaining said envelopes in a state of compression, wherein said band retains said plurality of envelopes in a state of compression such that said plurality of envelopes are compressed at least about 10% from their uncompressed state such that said plurality of envelopes are sufficiently compressed to generally seal ambient air out of said plurality of envelopes and to reduce absorption of moisture therein, and further wherein the state of compression is limited such that none of the banded envelopes bow out of plane by more than about 1/40 of the length of a given envelope.

15. The envelope package of claim 14 wherein each band is spaced apart from another given band.

16. An envelope package comprising:

a plurality of generally aligned envelopes, said plurality of envelopes being compressed together, the plurality of envelopes together defining a stack of envelopes having a center portion and two edge portions, said center portion having more layers thereat than either of said two edge portions due to a configuration of said individual envelopes; and

two or more generally non-elastic bands extending around said plurality of compressed envelopes and retaining said envelopes in a state of compression, wherein each envelope is generally flat and planar in the absence of outside forces, and wherein said plurality of envelopes are held in a limited state of compression by said bands such that said stack of envelopes does display bowing about said center portion thereof due to the relative number of layers thereat, yet such that none of the banded envelopes are bowed out of plane by more than about 1/40 of the length of a given envelope.

17. An envelope package comprising:

a plurality of generally aligned envelopes, said plurality of envelopes being compressed together; and

a pair or more of bands extending around the plurality of envelopes and retaining the envelopes in a state of compression such that the plurality of envelopes are compressed at least about 10% from their uncompressed state, the bands retaining the plurality of envelopes in a limited state of compression such that none of the banded envelopes are bowed out of plane by more than about 1/40 of the length of a respective envelope, at least one of the bands having a marking thereon indicating the orientation for processing of the plurality of banded envelopes.

18. The envelope package of claim 17, wherein the plurality of envelopes is sufficiently compressed to generally seal ambient air out of the plurality of envelopes and to reduce absorption of moisture therein.

19. The envelope package of claim 17, wherein the marking is an arrow.

20. The envelope package of claim 19, wherein the stack of envelopes is sufficiently compressed to generally seal ambient air out of the plurality of envelopes and to reduce absorption of moisture therein.

21. An envelope package comprising:

a plurality of generally aligned envelopes, said plurality of envelopes being compressed together, the plurality of envelopes together defining a stack of envelopes, the plurality of envelopes together defining a stack of envelopes having a center portion and two edge portions, said center portion having more layers thereat than either of said two edge portions due to a configuration of the individual envelopes; and

a pair or more of spaced-apart bands extending around the stack of envelopes and retaining the envelopes in a state of compression, the stack of envelopes displaying an amount of bowing in the center portion thereof due to the difference in the number of layers at the center portion relative to either of the two edge portions, the bands retaining the plurality of envelopes in a limited state of compression such that none of the banded envelopes are bowed out of plane by more than about 1/40 of the length of a respective envelope.
