Description
~04~59~3 1 The present invention relates to a packing carton for breakable articles, in particular eggs, consisting of a container member, a lid member hinged on the latter by means of an arti-cular fold, and a closing flap hinged on one of these members :
by means of an articular fold which when the lid member is closed over the container member engages in the respective other member, its outside lying opposite the inside of one of the side walls of this member, wherein at least one fastening -projection is provided on the outside of the flap, and at least ~`
10 one fastening opening is provided in the relative side wall to ;
accommodate the projection when the carton is closed.
When closing such a carton, problems may arise in ;practice from the parts hinged together being too strong1y inclined towards one another, and in particular from the closing flap being inclined inwards too far so that there cannot be a proper engagement between the fastening projection and fastening opening.
It has already been proposed to solve this problem by providing on the inside both of the closing flap and of the ~ adjacent container or lid member, protruberant supporting sur-faces which when the closing flap is tilted inwards come to lie against one another so that further inclination of the closing flap is prevented.
The present invention differs from this proposal in that on the inside of at least one of these articular folds, at least one projection is provided jutting from the articular fold. The projection may advantageously be oblong in the direction of the articular fold.
When the closing flap is turned inwards, this 3~ projection is wedged in between the parts of the carton adjacent ~.

1 to the closing fold, and therefore inhibits further pivoting of the flap.
According to a further development of the idea of the ~ invention, the projection may have a U-shaped cross-se~tion - such that the free ends of the U are joined to the axticular fold.
Advantageously the projection may be of smaller wall thickness at least in its middle section than the parts of the articular fold ad~acent to it.
The invention is explained in detail in the following with reference to the drawing.
Fig. 1 shows in the opened state the insides of an embodiment of a packing carton formed in accordance with the invention in the form of a specimen package.
Fig. 2 is a view on a larger scale o a cross-sectio:n through an articular fold of the carton in the region of a ' projection in the fold provided in accordance with the invention.
; Fig. 3 is a cross-section through an articular fold : in the region of a projection in which the fold is folded together.
The packing carton shown consists of a container ~ -member 1 and a lid member 2. rrhe two members are joined together by an articular fold 3. The carton is designed for packing eggs.
The container member has two parallel rows of egg ;
pockets 4, wherein five pockets 4 are placed in each row in the ; example illustrated. Disposed between the pockets placed next ... , ., -to each other in rows are protruberant supporting projections in the form of hollow pins 5 which define the pockets and act as supports for the lid member 2 when it is closed over the container member 1.
.,,
by means of an articular fold which when the lid member is closed over the container member engages in the respective other member, its outside lying opposite the inside of one of the side walls of this member, wherein at least one fastening -projection is provided on the outside of the flap, and at least ~`
10 one fastening opening is provided in the relative side wall to ;
accommodate the projection when the carton is closed.
When closing such a carton, problems may arise in ;practice from the parts hinged together being too strong1y inclined towards one another, and in particular from the closing flap being inclined inwards too far so that there cannot be a proper engagement between the fastening projection and fastening opening.

Advantageously the projection may be of smaller wall thickness at least in its middle section than the parts of the articular fold ad~acent to it.
The invention is explained in detail in the following with reference to the drawing.
Fig. 1 shows in the opened state the insides of an embodiment of a packing carton formed in accordance with the invention in the form of a specimen package.
Fig. 2 is a view on a larger scale o a cross-sectio:n through an articular fold of the carton in the region of a ' projection in the fold provided in accordance with the invention.
; Fig. 3 is a cross-section through an articular fold : in the region of a projection in which the fold is folded together.
The packing carton shown consists of a container ~ -member 1 and a lid member 2. rrhe two members are joined together by an articular fold 3. The carton is designed for packing eggs.
The container member has two parallel rows of egg ;
pockets 4, wherein five pockets 4 are placed in each row in the ; example illustrated. Disposed between the pockets placed next ... , ., -to each other in rows are protruberant supporting projections in the form of hollow pins 5 which define the pockets and act as supports for the lid member 2 when it is closed over the container member 1.

- 2 -' :
' 1~4~598 1 The lid member 2 has two parallel, protruberant gable members 6 which extend parallel to the rows of pockets and lie above these rows when the package is closed. 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 members.
10 indicates a number of inspection holes for the eggs. These holes are formed partly in the sides 6a of ~he gable members, and partly in the lid section 7. The number of holes 10 corres-ponds to the number of poc~ets 4 and they are disposed so as to lie opposite the pockets 4 when the package is closed. In the present example there are therefore five holes 10 in each gable member 6.
The dimensions of the package are such that when the package is closed the upper section of the gable members 6 is ; higher and the lid section 7 lower than the upper section of the ;
eggs placed in the package, and such that the gable members 6 are narrower than the said part of the eggs.
Consequently a part of the eggs is visible in the holes 10 when the package is closed, and may project a bit through the holes even so far as to come into contact with the edges of them and be held thereby.
The supporting projections S have a bearing surface 11 at their upper end.
Between the gable members 6, the lid member 2 is provided with counter-projections 12 with contact surfaces designed to rest on the surfaces 11 indicated by 13. In the example shown, the counter-projections 12 are formed as part of the sunken lid section 7.
When the package is closed the front surfaces of the projections 5 and 12 are adjacent ~o one another.
, A closing flap 15 is hinged on the container member 1 by means of an articular fold 14. This flap has two projections 16 on its outside. When the carton is closed the closing flap 15 is introduced into the lid member 2 and lies in it along the front inner wall 17 of the same. Fastening openings 18 corres-ponding to the two projections 16 are provided in the inner wall, through which the projections 16 project when the package is closed thereby holding the lid member 2 securely over the con-~: , :` tainer member 1.
: ' In accordance with the invention projections 19 whichprotrude from the articular fold, are provided in the articular folds 3 and 14. FigO 2 shows such a projection in the articular fold 1~ between the container member 1 and the closing flap 15.
The projection is oblong in the direction of the articular fold and has a U-shaped cross-section such that the free ends 20 of ~ -the U are joined to the articular fold. As a result an inter-ruption in the fold join is formed in the region limited by the free ends of the U. Fig. 1 shows a series of these projections 19 uniformly distributed along the articular folds 3 and 14, ~ 20 wherein in each case a projection is provided at the respective end of the fold. The projections may be of smaller wall thickness at least in their middle section than the adjacent parts of the articular fold, and if desired may even be more or less open. ~ -When pivoting the closing flap over the container member 1, as shown in Fig. 3, the projections 19 provided in the articular fold 1~ are wedged in between the adjacent parts, and -thus act as a barrier against further pivoting. The same applies to the projections in fold 3.
Naturally, the projections proposed in accordance with the invention can be used with the same or similar advantages ,' ' ., ,, . , .:
