Storage device having at least one storage container having a container housing with a housing wall bounding a storage space, wherein, in the outer surface of the housing wall, there is formed a card receptacle having a substantially rectangular outline, which is bounded at the edges at least by two lateral edge surfaces lying opposite each other at a distance in a transverse direction and by an upper edge surface extending between the two lateral edge surfaces, wherein, in the region of each of the two lateral edge surfaces, a holding rib each is located, which extends along the lateral edge surfaces, is located at a distance in front of a base surface of the card receptacle and defines, together with said base surface, a holding slot, and having at least one rectangular information carrier card, which is separate from the storage container and can optionally be placed in a standby position outside the card receptacle or in a position of use inserted into the card receptacle, wherein it dips in the position of use with each of opposite lateral card edge portions into one of the two holding slots, so that its dropping out of the card receptacle is prevented and it can be seen through an inspection opening laterally bounded by the two holding ribs, - wherein the card receptacle is bounded, on its underside located opposite the upper edge surface at a distance in a vertical direction, by a lower edge surface extending between the two holding ribs, wherein all edge surfaces (66, 67, 68, 69) are formed by a boundary frame, which frames the card receptacle peripherally, is designed integrally with a one-piece wall portion of the housing wall and which has an upper frame leg assigned to the upper edge surface of the circumferential wall and extending in the transverse direction, a lower frame leg likewise extending in the transverse direction and two lateral frame legs (64, 65) connecting the upper frame leg to the lower frame leg, mutually spaced in the transverse direction and extending in the vertical direction, - wherein each holding rib is shorter than the lateral edge surface of the card receptacle assigned thereto and each holding rib terminates with an upper end face at a distance from the upper edge surface of the card receptacle, wherein the gap formed thereby in each case defines a card insertion gap, through which the information carrier card, having resiliently flexible properties, can be moved from the standby position into the position of use in connexion with a reversible bending process while the lateral card edge portions are simultaneously inserted into the holding slots from above, - and wherein the boundary frame is in the region of the lower edge surface of the card receptacle locally interrupted by a reach-in slot, the length of which is less than the clear distance between the two holding ribs and through which the information carrier card, being in the position of use, can be gripped from behind with a finger and pulled into the standby position through the inspection opening while being bent and buckled elastically, characterised in that the container housing consists of plastic, wherein each holding rib is designed integrally with one of the two lateral frame legs (64, 65) and moulded to that longitudinal side thereof which faces the card receptacle, and wherein only that lower frame leg of the boundary frame which defines the lower edge surface of the card receptacle has a reach-in slot, the boundary frame being otherwise continuous. - wherein the card receptacle is bounded, on its underside located opposite the upper edge surface at a distance in a vertical direction, by a lower edge surface extending between the two holding ribs, wherein all edge surfaces (66, 67, 68, 69) are formed by a boundary frame, which frames the card receptacle peripherally, is designed integrally with a one-piece wall portion of the housing wall and which has an upper frame leg assigned to the upper edge surface of the circumferential wall and extending in the transverse direction, a lower frame leg likewise extending in the transverse direction and two lateral frame legs (64, 65) connecting the upper frame leg to the lower frame leg, mutually spaced in the transverse direction and extending in the vertical direction, - wherein each holding rib is shorter than the lateral edge surface of the card receptacle assigned thereto and each holding rib terminates with an upper end face at a distance from the upper edge surface of the card receptacle, wherein the gap formed thereby in each case defines a card insertion gap, through which the information carrier card, having resiliently flexible properties, can be moved from the standby position into the position of use in connexion with a reversible bending process while the lateral card edge portions are simultaneously inserted into the holding slots from above, - and wherein the boundary frame is in the region of the lower edge surface of the card receptacle locally interrupted by a reach-in slot, the length of which is less than the clear distance between the two holding ribs and through which the information carrier card, being in the position of use, can be gripped from behind with a finger and pulled into the standby position through the inspection opening while being bent and buckled elastically,
