Abstract

The packaging box for bottles is made from a blank in a flexible foldable material that comprises two similar body panels which are foldable against each other about a lateral generatrix and that form together a side wall for said box when their remote side edges are secured together, so that said box can be shelved flat in a collapsed form. The blank further comprises two symetrical bottom elements having the shape of a half-section of the bottom face of said box, with two bottom flaps connected each along the diameter of one of said bottom elements. The two bottom flaps are securable flat on each other into a grip for pushing said bottom elements into said side wall where they are blocked by jamming, thereby erecting said box, that further constitutes a strengthening element for said bottom face of said box.

Claims

1. A packaging box for bottles, made from a blank in a flexible foldable material, such as cardboard comprising

two similar body panels which are foldable against each other about a lateral generatrix and that form together a side wall for said box when their remote side edges are secured together, whereby said box can be shelved flat in a collapsed form,

two symetrical bottom elements having the shape of a half-section of the bottom face of said box, each of said bottom elements being foldably connected respectively to one of said body panels,

a bottom flap foldably connected to each of said bottom elements along a diameter of said bottom face at a free edge of each respective bottom element,

the two bottom flaps being securable flat on each other along said diameter into a grip for pushing said bottom elements into said side wall, where they are blocked by jamming, thereby erecting said box, and further constituting a strengthening element for said bottom face of said box.

2. A packaging box as claimed in claim 1, wherein each of said bottom elements is attached respectively to said body panels through an intermediate laterally strengthening panel, that is substantially of the same width as said bottom flaps, and which is folded towards the inside of said side wall and secured thereon, so that said bottom elements are retracted in said side wall and the free edge of each of said intermediate panels forms, with the lower edge of said side wall, a support base for said box.

3. A packaging box as claimed in claim 1, wherein the remote side edges of said body panels are secured to each other through an attaching panel connected to the outer vertical side edge of one of said body panels and secured to the outer vertical side end of the other body panel.

4. A packaging box as claimed in claim 2, wherein the remote side edges of said body panels are secured to each other through an attaching panel connected to the outer vertical side edge of one of said body panels and secured to the outer vertical side end of the other body panel, and wherein one of said intermediate panels is cut out from a length which is substantially equal to the width of said attaching panel.

5. A packaging box as claimed in claim 1, wherein said bottom flaps comprise on both vertical side edges a non-secured extension that folds towards said flaps during the erection of said box.

6. A packaging box as claimed in claim 1, wherein said body panels have the shape of a rectangular trapezium, whereby said box has a frustoconical shape.

7. A packaging box as claimed in claim 1, wherein each body panel comprises, next to each of its vertical side edges, a fold line parallel to said edge, whereby said box has an oval section.

8. A packaging box as claimed in claim 1, wherein three upper strengthening flaps and a cover element are connected to the upper edge of said side wall.

9. A packaging box as claimed in claim 1, wherein each of said body panels is connected to a median cover element having the shape of a half-section of the top face of said box.

10. A packaging box as claimed in claim 9, wherein each cover element comprises two half-sections joined by a strip into which is arranged a central aperture, and wherein each cover element comprises an insertion flap projecting out of the diameter of one of its half-sections, which insertion flap is intended to engage itself in the aperture of the other cover element, the two insertion flaps being situated on opposite half-sections of said cover elements.

11. A packaging box as claimed in claim 10, wherein each aperture comprises, on its side opposite to the insertion flap of the corresponding cover element, two shoulders for centring the flap of the other cover element.

12. A packaging box as claimed in claim 1, wherein the side wall section is fitted to that of the bottle to be packed, at least substantially close to its bottom.

13. A packaging box as claimed in claim 1, wherein all the elements belonging to said blank are connected together by fold lines.

14. A packaging box for bottles that is made of a blank in a flexible foldable material and comprises, when in an easily erectable collapsed state:

two similar body panels folded against each other about a lateral generatrix and that form together a side wall for said box,

two symetrical bottom elements having the shape of a half-section of the bottom face of said box,

a bottom flap foldably connected to each of said bottom elements along a diameter of said bottom face at a free edge of each respective bottom element, the two bottom flaps being secured flat on each other,

each of said bottom flaps comprising on both vertical side edges a non-secured extension,

an attaching panel connected to the outer vertical side edge of one of said body panels and secured to the outer vertical side end of the other body panel, inside said side wall,

and two intermediate laterally strengthening panels that are substantially of the same width as said bottom flaps, each of said intermediate panels connecting one of said bottom elements and one of said body panels, and which are folded towards the inside of said side wall and secured thereon,

one of said intermediate panels being cut out from a length which is substantially equal to the width of said attaching panel,

all said panels, flaps and elements in said blank being connected together by fold lines.

15. A packaging box as claimed in claim 14, wherein the side wall section is fitted to that of the bottle to be packed, at least substantially close to its bottom.

16. A packaging box as claimed in claim 14, wherein each body panel comprises, next to each of its vertical side edges, a fold line parallel to said edge, whereby said box has an oval section.

17. A packaging box as claimed in claim 14, wherein each body panel is foldably connected to a median cover element having the shape of a half-section of the top face of said box, each cover element comprising two half-sections foldably joined by a strip into which is arranged a central aperture, and an insertion flap projecting out of the diameter of one of its half-sections, which insertion flap is intended to engage itself in the aperture of the other cover element, the two insertion flaps being situated on opposite half-sections of said cover elements, and wherein each aperture comprises, on its side opposite to the insertion flap of the corresponding cover element, two shoulders for centring the insertion flap of the other cover element.

18. A packaging box for bottles, in a collapsed state, easily erectable, made from a blank in a flexible foldable material such as cardboard comprising

two similar body panels having the shape of a rectangular trapezium, folded against each other about a lateral generatrix, and that form together a side wall for said box,

two symetrical bottom elements having the shape of a half-section of the bottom face of said box,

a bottom flap connected along a diameter of said bottom face to each of said bottom elements, the two bottom flaps being secured flat on each other,

an attaching panel connected to the outer vertical side edge of one of said body panels and secured to the outer vertical side end of the other body panel, inside said side wall,

two intermediate laterally strengthening panels that are substantially of the same width as said bottom flaps, each of said intermediate panels connecting one of said bottom elements and one of said body panels, and which are folded towards the inside of said side wall and secured thereon,

one of said intermediate panels being cut out from a length which is substantially equal to the width of said attaching panel,

and three upper strengthening flaps and a cover element connected to the upper edge of said side wall,

all panels, flaps and elements in said blank being connected together by fold lines.

19. A packaging box as claimed in claim 18, wherein the side wall section is fitted to that of the bottle to be packed, at least substantially close to its bottom.
