The present invention relates to a container comprising foldable sidewalls which has a hinge connection which almost entirely prevents the base from slumping relative to the sidewall even under load, The container may be produced in a particularly simple and inexpensive manner, since due to the specific hinge connection, the base may be produced, in an injection-molding process, without any slide in the tool, and since a simple tool arrangement is thus enabled.

1. A container, comprising: a container base and at least two sidewalls that are foldable onto the container base,wherein the foldable sidewalls are articulated relative to the base by means of hinges,wherein the hinges comprise a hinge pin which in an upright position of the foldable sidewall is held, within an orifice in the container base that corresponds to the hinge pin, against being pulled out from the orifice,wherein at least one catch lug is provided which unilaterally protrudes from the hinge pin in the direction transverse to the alignment of the hinge pin,wherein the hinge pin is held within the orifice such that, when the sidewall is folded open, the catch lug acts on a wall of the orifice to cause an eccentric movement of the hinge pin in the orifice,wherein the hinge pin, in the folded-open position of the sidewall, is held within the orifice by at least one protrusion formed in the orifice,wherein the catch lug, in the folded-open position of the sidewall, acts on the wall of the orifice thereby fixing the hinge pin within the orifice underneath the protrusion, andwherein the sidewall comprises at least one support which interacts with the base and forms, in the upright position of the sidewall, a mechanical barrier against further folding-open of the sidewall. 2. The container as claimed in claim 1, wherein at least one insertion lug is provided within the orifice for clamp-like reception of the hinge pin within the orifice. 3. The container as claimed in claim 1, wherein the catch lug is integrally formed on the hinge pin, specifically in the orientation perpendicular to the extension of the sidewall, so that the hinge pin may be removed from the orifice in the position where the sidewall is folded onto the container base. 4. The container as claimed in claim 1, wherein the hinge pin is centrally attached to the sidewall by means of at least one hinge pin ridge, and in that two pairs of opposite and counteracting insertion lugs are configured within the orifice on either side of the hinge pin ridge(s). 5. The container as claimed in claim 4, wherein the protrusion holding the hinge pin is configured underneath at least two adjacent insertion lugs. 6. The container as claimed in claim 1, wherein the support is configured as a catch lug which, in the upright position of the sidewall, engages behind a protrusion of an oblique wall in the base. 7. The container as claimed in claim 1, wherein the support is configured as a surface element which, in the upright position of the sidewall, adjoins a corresponding surface element of the base, the surface elements being protected, in an upright position of the sidewall, against mutual displacement in the normal direction of the surface elements, and the two surface elements extending in the direction of extension of the upright sidewall.
