| (54) | Box provided with a lid hingedly connected thereto |
| (57) The invention relates to a box, comprising:
a container (1) which is provided on one side with at least one outwardly forced first hinge part (23); a sheet-metal lid (4) which is provided with a corresponding number of lips (56) which each form a second hinge part and are curved inward; which first and second hinge parts form part of a hinge; which lid (4) in the closed situation of the box has an edge (9) engaging over the rim (8) of the container (1), which edge (9) remote from the or each hinge (2,5,3,6) is a first curled edge (10) such that the free, sharp end edge (11) of the sheet-metal lid (4) is received in the curled edge (10) such that contact with a user is prevented. The box according to the invention has the feature that said edge (9) has a form in the zone adjoining a hinge (2,5,3,6) such as to prevent a user making contact with the free, sharp end edge (12) of the sheet-metal lid (4) in this zone. |
[0001] The invention relates to a box, comprising:
a container which is provided on one side with at least one outwardly forced first hinge part;
a sheet-metal lid which is provided with a corresponding number of lips which each form a second hinge part and are curved inward;
which first and second hinge parts form part of a hinge;
which lid in the closed situation of the box has an edge engaging over the rim of the container, which edge remote from the or each hinge is a first curled edge such that the free, sharp end edge of the sheet-metal lid is received in the curled edge such that contact with a user is prevented.
[0003] A drawback to the known box is that the lid has an edge in the zone adjoining a hinge which consists of a non-modelled sheet-metal part which, due to the small thickness of the sheet-metal lid, has a sharp end edge. It may occur that in handling the box a user injures his fingers on such a sharp edge.
[0004] It is an object of the invention to embody a box of the stated type such that it does not have the mentioned drawback.
[0005] In respect of this objective the box according to the invention has the feature that said edge has a form in the zone adjoining a hinge such as to prevent a user making contact with the free sharp end edge of the sheet-metal lid in this zone.
[0007] Another embodiment has the special feature that said edge in said zone is a second curled edge.
[0008] This latter variant can advantageously have the special feature that the first curled edge is formed integrally with the second curled edge.
[0009] It is noted that the latter described two variants can advantageously be manufactured such that the curled edge or all curled edge parts can be formed by a shaping tool in one simultaneous process.
[0010] Yet another embodiment has the feature that a hinge comprises a hinge pin extending through the first and the second hinge parts.
[0011] This latter embodiment has the drawback that a separate component, i.e. the hinge pin, is required to form the hinge.
[0012] In this latter context an advantageous embodiment has the special feature that the first and the second hinge parts co-act directly with each other to form a hinge.
[0013] The invention will now be elucidated with reference to the annexed drawings. Herein:
figure 1 shows a partly perspective view of a box according to the invention in a first embodiment;
figure 2 shows the cross-section II-II of figure 1;
figure 3 is a partly perspective view of a second embodiment;
figure 4 shows the cross-section IV-IV of figure 3;
figure 5 is a partly perspective view of a third embodiment;
figure 6 shows the cross-section VI-VI of figure 5;
figure 7 is a partly perspective view of the lid according to figure 1; and
figure 8 shows a view corresponding with figure 7 of a variant.
[0014] Figure 1 shows a box consisting entirely of sheet-metal, comprising a container 1 which is provided on one side with two outwardly forced first hinge parts 2, 3, a sheet-metal lid 4 which is provided with two lips 5, 6 which each form a second hinge part and are curved inward. The associated first and second hinge parts form part of a hinge.
[0015] In the closed situation of box 7 the lid 4 has an edge 9 gripping over the rim 8 of container 1, which edge remote from hinges 2, 5; 3, 6 is a first curled edge 10 such that the free, sharp end edge 11 of lid 4 is received in curled edge 10 such that contact with a user is prevented.
[0016] Said edge 9 has a form in the zones adjoining hinges 2, 5; 3, 6 such as to prevent contact by a user with the free, sharp end edge 12 of sheet-metal lid 4 in these zones. Said edge is bent inward in said zones for this purpose. These edge zones are designated 13, 14, 15.
[0017] It will be particularly apparent from figure 2 that the inward bent sharp end edge 12 has a relative position such that contact with a user is effectively prevented.
[0018] Figures 3 and 4 show a variant which corresponds by and large with the embodiment of figures 1 and 2. Box 33 according to these figures 3 and 4 has only one hinge which in principle is embodied in the same manner as hinges 2, 5; 3, 6. In this embodiment a first hinge part 14 is comparatively long and co-acts with an inwardly curved, equally long lip 15 formed on lid 16. The sharp end edges to which the invention relates are designated respectively 17 and 18. As shown particularly clearly in figure 4, this sharp end edge is bent inward in the same way as edge 12 of figures 1 and 2.
[0019] Figures 5 and 6 show a box 19 wherein sharp end edge 20 is made inaccessible to a user in a manner other than in figures 1-4. The curled edge 10, for which the end edge of the lid 21 according to the invention is formed, is described with reference to figures 1 and 2. In the case of lid 21 this curled edge extends to a position close to hinges 2, 5; 3, 6 and therebetween. The diverse curled edge parts are designated respectively 22, 23, 24. It will be apparent that in this way the sharp end edge 20 is effectively made inaccessible.
[0020] Figure 7 shows the lid 4 according to figure 1 at the stage in which lips 5 and 6 have not yet been bent to form the hinges drawn in figure 1. It will be apparent that the longitudinal edges of the lips 5, 6, all designated 27 for the sake of convenience and extending transversely of edges 13, 14, 15, have been cut with a sharp edge and are therefore themselves sharp.
a container which is provided on one side with at least one outwardly forced first hinge part;
a sheet-metal lid which is provided with a corresponding number of lips which each form a second hinge part and are curved inward;
which first and second hinge parts form part of a hinge;
which lid in the closed situation of the box has an edge engaging over the rim of the container, which edge remote from the or each hinge is a first curled edge such that the free, sharp end edge of the sheet-metal lid is received in the curled edge such that contact with a user is prevented,
characterized in that
said edge has a form in the zone adjoining a hinge such as to prevent a user making contact with the free, sharp end edge of the sheet-metal lid in this zone.
