1479757 Cartons; egg boxes BRODRENE HARTMANN AS 21 Aug 1974 [31 Aug 1973] 36759/74 Heading B8P In a packing carton, e.g. for eggs, which comprises hinged together a container member 1, a lid member 2, and a closing flap 15 which is hinged to one of the container and lid members and in the closed position extends within and engages the other member by means of fastening projection(s) 16 and interlocking aperture(s) 18, at least one of the hinge portions is provided with slot shaped apertures (indicated at 19) distributed along the hinge portion, the spacing between the apertures being greater than the lengths of the apertures and there being a respective aperture at each end of the hinge portion. The apertures may be covered by respective projections (Figs. 2 and 3, not shown) which are U-shaped in cross-section transverse to the hinge line and extend inwardly of the packing carton.

Description

Packing carton article Aktieselskabet 2800 Packing Carton for Breakable The present invention relates to a packing carton for in particular consis ing of a container a lid member hinged on the latter by means of an articular and a closing flap hinged on one of these members by means of an articular fold which when the lid member is closed the container member engages in the respective other its outside lying opposite the inside of one of the side walls of this wherein at least one fastenin projection is provided on the outside of the and at least one fastening ing is provided in the relative side wall to accommodate the projectio when the carton is When closing such a problems may arise in practice from the articular folds being torn or ruptured on closing the cart This is particularly applicable in the case where the carton is made of relatively brittle such as is the purpose of the present invention to solve this and this is achieved in accordance with the invention in that at least one of these articular and preferably that which joins the container to the lid where the bending stress is frequently has rooooooc apertures which are running in the direction the and are distributed at several positions over its wherein the spacing between the rooooooo or apertures is a multiple of the length of the It has been shown that in this manner the danger of the articular folds tearing or rupturing on mutually pivoting the carton members to close carton can be met effectively without the durability of the articular joint between the members being The roooccoo or apertures in accordance with the be covered over by a projection of protruding from the inside of the articular which on mutual pivoting of the carton members hinged together may serve as an aid to braking or damping the pivoting By this means the danger of too strong an action on the articular can be further In accordance with the the projection may be of smaller wall thickness at least in its middle section than the adjacent parts of the articular It is advantageous according to the invention for a or an aperture to be provided at each end o articular invention is explained in detail in the following with reference to the 1 in open insides of an embodiment of a packing carton formed in accordance with the invention in the form of a speciment 2 is a view on a larger scale of a through an articular fold of the carton in the region of a projection in the fold provided in accordance with the a through an articular fold in the region of a in which the fold is folded The packing carton shown consists of a container member 1 and a lid member The two members are joined together by an articular The carton is designed for packing The container member has two parallel rows of egg pockets wherein five pockets 4 are placed in each row in the example Disposed between the pockets adjacent other in rows are protruberant supporting projections in the form of hollow pins which define the pockets and act as supports the lid member 2 when it is closed over the container The lid member 2 two protruberant gable members which extend parallel to the rows of pockets and lie above these rows when the package is Extending between the gable members is a sunken lid section 7 which joins together the lower edges of the facing sides 6a of the gable indicates a number of inspection holes for the These holes are formed partcly in the sides 6a of the gable and partly in the lid section The number of holes corresponds to the number of pockets and they are disposed so as to lie opposite the pockets 4 when the package is In the present there are therefore five holes 10 each gable member The dimensions of the package are such that when the package is the upper section of the gable members 6 is and the lid section 7 lower than the upper section of the eggs placed in the and such that the gable members are narrower than the said part of the Consequently a part of the eggs is visible in the holes 10 when the package is and may project a bit through the even so far as to come into contact with the edges of them and be held The supporting projections have a bearing surface 11 at their upper Between the gable members the lid member 2 is provided with 12 with contact surfaces designed to rest on the surfaces indicated by In the example the 12 are formed as part of the sunken lid section the package is the front surfaces of the pro ections 5 and 12 are adjacent to one A closing flap is hinged on the container member 1 by means of an articular fold This flap has two projections on its the carton is the closing flap 15 is introduced into the lid member 2 and lies in it alon the front inner wall 17 of the Fastening openings 18 corresponding to the two projections are provided in the inner through which the projections 16 project when the package is thereby holding the lid member 2 securely ove the container member In the embodiment recesses apertures 20 running in the direction of the fold are provided in both articular folds and the spacing between the recesses o apertures being a multiple of the length of the same In the embodiment the or apertures are covered over by a projection of protruding from the inside the articular 2 shows such or aperture with a projection in the articular fold 14 between the container member 1 and the closing flap or and thus also the o are oblong in the direction of the articular and the ection is of such that the free ends of the U are joined to the articular As a result an interruption in the fold join is formed in the region limited by the free ends of the 1 shows a series of these projections covering these or uniformly distributed along the articular folds and wherein in each case a projection is provided at the respective end of the The projections 19 may be of smaller thickness at least in their section than the adjacen parts of the articular and if desired even be more or less When pivoting the closing flap over the container member shown in 3 the projection 19 is wedged in between the the and thus acts as a barrier against further Naturally the or apertures proposed in accordance with the invention can be with the same or advantages to those in other packages than the type shown by way of insufficientOCRQuality
