The invention relates to a collapsible container having a container base and four collapsible walls. The catch mechanism for the lockable lateral walls in their upright assembled condition is a resilient pivotable lock member contained within a recess of the lateral wall having a projecting tongue latching member that cooperates with opposing ramps of a locating lug located on the adjacent wall member to lock the adjacent walls to each other.

What is claimed is: 1. A container comprising: a container base; and four lateral walls; each said lateral wall of said four lateral walls being hinged to said container base and collapsible inwards onto said container base; two first opposing lateral walls of said four lateral walls, each first lateral wall of said two first opposing lateral walls having a recess located therein, said recess positioned adjacent an edge of each wall of said two first opposing lateral walls; and a bushing-type opening mounted in said first lateral wall, said bushing-type opening positioned within the confines of said recess; a resilient pivoting lock member mounted within said recess of said first lateral wall, said resilient pivoting lock member having a pivot pin mounted in said bushing-type opening for mounting said resilient pivoting lock member in said recess of each wall of said two first opposing lateral walls for pivotable movement relative to said first lateral wall; and a projecting tongue latching member; and two second opposing lateral walls of said four lateral walls, each second lateral wall of said two second opposing lateral walls having a locating lug spaced a predetermined distance from an edge of said second opposing lateral wall, said locating lug having opposing ramped surfaces thereon; such that each said wall of said two first opposing lateral walls are releasably lockable with a respective wall of said two second opposing lateral walls whereby as each wall of said two first opposing lateral walls are moved from a collapsed position adjacent said container base to an upright position, said projecting tongue latching member of said resilient pivoting lock member cooperates with one of said ramped surfaces of said locating lug mounted on each respective wall of said two second opposing lateral walls, to pivot said resilient pivoting lock member in one direction and further cooperate with a second ramp surface of said locating lug to pivot said resilient pivoting lock member in an opposite direction and snap lock into place, in an upright position, behind said locating lug at the edges of each of said two second lateral walls for purposes of locking said four assembled lateral walls. 2. The collapsible container as claimed in claim 1 wherein said resilient pivoting lock member of each said first lateral wall is attached to a respective one of each said second lateral wall via said pivot pin/bushing connection. 3. The collapsible container as claimed in claim 1, wherein in order to accommodate said resilient pivoting lock member, said bushing-type opening is provided in each said first lateral wall, said resilient pivoting lock member configured with said pivot pin member for inserting into said bushing-type opening; and wherein said pivot pin further comprises a plurality of flare-shaped latches mounted at one end; and a pair of radial slits whereby the diameter of said pivot pin can be reduced elastically to allow insertion of said pivot pin into said bushing-type opening and said plurality of latches on said pivot pin grip of each said first lateral wall from behind when said pivot pin is seated, thus locking said pivot pin in position. 4. The collapsible container as claimed in claim 1, wherein said resilient pivoting lock member is configured as a circular-sector-shaped member around said centrally mounted pivot pin. 5. The collapsible container as claimed in claim 1, wherein said resilient pivoting lock member is mounted in said recess of each said first lateral wall in such manner as to be substantially flush therewith. 6. The collapsible container as claimed in claim 1, wherein in the locked position, said resilient pivoting lock member is pretensioned. 7. The collapsible container as claimed in claim 6, wherein said resilient pivoting lock member further comprises a pretensioning spring; and each said first lateral wall further comprises a stop configured in each said first lateral wall. 8. The collapsible container as claimed in claim 7, wherein said pretensioning spring is mounted in spaced relation to said stop such that when said resilient pivoting lock member is in the disengaged position, that is, with an opening movement of said resilient pivoting lock member, said resilient pivoting lock member is pretensioned in the direction of the locking or engaging position. 9. The collapsible container as claimed in claim 1, wherein said projecting tongue latching member in the engaged position, engages behind said locating lug on said second lateral wall. 10. The collapsible container as claimed in claim 7, said projecting tongue latching member further comprises opposing ramped surfaces on a forward edge thereof, and wherein said ramped surfaces on said locating lug have complementary ascent ramps in the form of inclined surfaces, such that when said first lateral wall is folded upwards, said resilient pivoting lock member is rotated by said projecting tongue latching member as they ascend said complementary ramps of said locating lug, and said pretensioning spring is tensioned against said stop while building up restoring forces, whereby said projecting tongue latching member engage behind said locating lug when said first lateral wall is in an upright position. 11. The collapsible container as claimed in claim 7, wherein said pretensioning spring is shaped in the form of an arcuate flexible tongue. 12. The collapsible container as claimed in claim 1, wherein said resilient pivoting lock member further comprises an actuating grip member. 13. The collapsible container as claimed in claim 3, further comprising a catch member mounted on said resilient pivoting lock member; and an arcuate guide element in the form of an oblong hole located in said recess of said first lateral wall, said arcuate guide element limiting the rotary movement of said resilient pivoting lock member in both directions of rotation. 14. The collapsible container as claimed in claim 13, wherein said resilient pivoting lock member further comprises a safety catch mounted in an upper edge of said first lateral wall such that when said resilient pivoting lock member performs an opening movement, said safety catch moves in an upward direction from said upper edge of said first lateral wall in such manner that if a container is stacked on top of the container in question, the exiting movement of said safety catch and hence the opening movement of said resilient pivoting lock member is blocked by said top container. 15. The collapsible container as claimed in claim 14, wherein said safety catch comprises a pin or bolt member mounted integral with said upper edge of said first lateral wall and extending into said recess in a direction towards said resilient pivoting lock member. 16. The collapsible container as claimed in claim 1, further comprising at least one detent member mounted along an edge of said second opposing lateral wall in spaced relation to said locating lug of said second opposing lateral wall said at least one detent adjoining the corners of said first lateral wall and said second opposing lateral wall when said first and second lateral walls are in an upright position. 17. The collapsible container as claimed in claim 16, wherein said at least one detent further comprises a detent member mounted adjacent said locating lug. 18. The collapsible container as claimed in claim 16, wherein said at least one detent comprises additional detent members located at the upper and lower edges of said first lateral wall said additional detent members cooperating with said second lateral wall to connect thereto. 19. The collapsible container as claimed in claim 18, wherein said additional detent members are configured with grooves and said second opposing lateral wall further comprises complementary flexible elements located at the upper and lower edges of said second lateral wall to engage said configured grooves of said additional detent members to form a tongue-and-groove connection when said four lateral walls are in an upright position. 20. The collapsible container as claimed in claim 1, wherein said resilient pivoting lock members are each mounted in an upper corner area of the respective said first lateral wall of said collapsible container. 21. The collapsible container as claimed in claim 17, wherein the distance between said at least one detent member and said locating lug is essentially corresponding to the width of said projecting tongue latching member for wobble-free arrangement.
