Description
~ 4~
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 articular 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 one fastening opening is 10 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 articular folds being torn or ruptured on closing the carton. This is particularly applicable in the case ; where the carton is made of-relatively brittle material, such as papier-maché. ~ ;
It is the purpos~ of the present invention to solve this problem, and this is achieved in accordance with the invention in that at least one of these articular folds, and preferably that which joins the container member to the lid member, where the bending stress is frequently greatest, has slot-shaped -- apertures which axe oblong, running in the direction of the fold and are distributed at several positions over its length, wherein the spacing between the apertures is a multiple of the length of the same. 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 the carton can be met effectively without the durability of the articular joint ;~
between the members being impaired.
The apertures may in accordance with the ~.', ,.. ~.:. . : .
10~
1 invention, be covered over by a projection of ~-shaped cross-section protruding from the inside of the articular fold, which on mutual pivoting of the carton members hinged together may serve as an aid to braking or damping the pivoting movement. By this means the danger of too strong an action on the articular fold can be further avoided.
In accordance with the invention, the projection may be of smaller wall thic~ness at least in its middle section than the adjacent parts of the articular fold. It is also advantageous according to the invention for a-~e4e~ r an aperture to be - ~ ` provided at each end of the articular fold.
The invention is explained in detail in the following with reference to the drawing.
Fig. 1 shows, in the open state ! the insides of an em-bodiment 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 of a cross-section ~-through an articular fold of the carton in the region of a projection in the fold provided in ~ccordance 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. The two members are joined together by an articular fold. 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 adjacent 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 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 the gable members, and partly in the lid section 7. ~he number of holes 10 corresponds to the number of pockets 4, and they are disposed so as to lie opposite the pockets 4 when the packageis 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 5 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 o~
the projections 5 and 12 are adjacent to one another.

A closing flap 15 is hinged on the container member 1 by means of an articular fold 14. This flap has kwo 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 correspond- .
:~ ing to the two projections 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 container member 1.
In the embodiment illustrated, oblong, slot-shaped apertures 20 running in the direction of the fold are provided in both articular folds 3 and 14, the spacing ~ .
between the apertures béing a multiple of the length -of the same. In the embodiment shown, the apertures are covered over by a projection of U-shaped cross-section .
protruding from the inside of the articular fold.
Fig. 2 shows such an aperture with a pro-jection in the articular fold 14 betwe n the container member 1 and the closing flap 15.

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 articular 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 one fastening opening is 10 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 articular folds being torn or ruptured on closing the carton. This is particularly applicable in the case ; where the carton is made of-relatively brittle material, such as papier-maché. ~ ;
It is the purpos~ of the present invention to solve this problem, and this is achieved in accordance with the invention in that at least one of these articular folds, and preferably that which joins the container member to the lid member, where the bending stress is frequently greatest, has slot-shaped -- apertures which axe oblong, running in the direction of the fold and are distributed at several positions over its length, wherein the spacing between the apertures is a multiple of the length of the same. 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 the carton can be met effectively without the durability of the articular joint ;~
between the members being impaired.
The apertures may in accordance with the ~.', ,.. ~.:. . : .
10~
1 invention, be covered over by a projection of ~-shaped cross-section protruding from the inside of the articular fold, which on mutual pivoting of the carton members hinged together may serve as an aid to braking or damping the pivoting movement. By this means the danger of too strong an action on the articular fold can be further avoided.
In accordance with the invention, the projection may be of smaller wall thic~ness at least in its middle section than the adjacent parts of the articular fold. It is also advantageous according to the invention for a-~e4e~ r an aperture to be - ~ ` provided at each end of the articular fold.
The invention is explained in detail in the following with reference to the drawing.
Fig. 1 shows, in the open state ! the insides of an em-bodiment 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 of a cross-section ~-through an articular fold of the carton in the region of a projection in the fold provided in ~ccordance 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. The two members are joined together by an articular fold. 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 adjacent 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 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 the gable members, and partly in the lid section 7. ~he number of holes 10 corresponds to the number of pockets 4, and they are disposed so as to lie opposite the pockets 4 when the packageis 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 5 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 o~
the projections 5 and 12 are adjacent to one another.

A closing flap 15 is hinged on the container member 1 by means of an articular fold 14. This flap has kwo 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 correspond- .
:~ ing to the two projections 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 container member 1.
In the embodiment illustrated, oblong, slot-shaped apertures 20 running in the direction of the fold are provided in both articular folds 3 and 14, the spacing ~ .
between the apertures béing a multiple of the length -of the same. In the embodiment shown, the apertures are covered over by a projection of U-shaped cross-section .
protruding from the inside of the articular fold.
Fig. 2 shows such an aperture with a pro-jection in the articular fold 14 betwe n the container member 1 and the closing flap 15. The aperture, and thus also ~ the projection, are oblong in the dlrection of the articular fold, and the projection is of U~shaped cross-section such that the free ends of the U are joined to the articular fold. As a result an interruption in the fold join is formed in the region Iimited by the free ends of the U. Fig. l shows a series of these projections 19 covering these apertures, uniformly distributed along the articular folds 3 and 14,wherein in each case a projection is provided at the respective end of the fold. The projections l9 may be of smaller wall thickness at least in their middle sectiQn than the adjacent parts of the articular fold, and if desired may even be more or less open.
48~;7 1 When pivoting the closing flap over the container member 1 t as shown in Fig. 3 the projection 19 is wedged in between the adjacent parts, and thus acts as a barrier against further pivoting.
Naturally the-~ees~es-~ apertures proposed in - ~ ~ accordance with the invention can be used, with the same or similar advantages to those explained, in other packages than the type shown by way of example.
