6. A travel container as claimed in claim 5, characterized in that said second elastic means provide said pushing block (64) with a force tending to approach said telescopic strap (5).

7. Travel container according to claim 5, characterized in that said stop means (6) comprise a second lever, said second elastic means and said pushing block (64) being located at the two ends of said second lever, respectively, said second elastic means being connected to said insertion block (63) through said second lever.

8. Travel container according to any one of claims 1 to 2, characterised in that said stop means (6) further comprise a connecting element (65) fixed with respect to said second container portion (3) and a strap support (66) for supporting the telescopic strap (5), said strap support (66) and one end of said first elastic means (61) being connected to said connecting element (65).

9. Travel container according to any one of claims 1 to 2, characterised in that the side of the end of the insert block (63) for insertion into the latching hole or latching groove facing the first container part (1) is the end side with a curved surface (631) or inclined surface and/or the wall of the latching hole or latching groove facing the second container part (3) is the wall with a curved surface or inclined surface; after the insertion block (63) is inserted into the clamping hole, the first box body part (1) or the second box body part (3) is pressed or the telescopic belt (5) is pulled, and the hole wall of the clamping hole or the groove wall of the clamping groove inserted into the insertion block (63) can jack up the insertion block (63) by pushing the side surface of the end part, so that the volume of the suitcase is reduced; one side of the end part departing from the first box body part (1) is used for clamping the clamping hole or the clamping groove, so that when the inserting block (63) is inserted into the clamping hole or the clamping groove, the volume of the travel box is limited to increase.

10. Travel container according to any one of claims 1 to 2, characterized in that it further comprises box extension means (4), said box extension means (4) being intended to provide a force for extending said telescopic portion (2) so as to tend to expand the volume of said travel container.

11. Travel container according to claim 10, characterized in that said box stretching means (4) comprise a first and a second lever hinged in an X-shape and comprising third elastic means, the first ends of said first and second levers being connected in translation with said first box portion (1) and the second ends of said first and second levers being connected in translation with said second box portion (3), said third elastic means exerting a force on said first and second levers that stretches said telescopic portion (2).

12. A travel container according to claim 11,

the third elastic device comprises a torsion spring arranged at the hinged part of the first rod and the second rod; and/or the presence of a gas in the gas,

the third elastic means comprise compression springs arranged between the first tank portion (1) and the first end of the first rod, between the first tank portion (1) and the first end of the second rod, between the second tank portion (3) and the second end of the first rod or between the second tank portion (3) and the second end of the second rod; and/or the presence of a gas in the gas,

13. A travel container according to any one of claims 1 to 2, characterised in that said telescopic portion (2) comprises an accordion-like compression band, the projections of which are provided with high-strength carbon fibre rods.
