THIS ENVELOPE HAS THE GENERAL FORM OF A RIGHT PRISM 1, PREFERRED REGULAR, THE SECTION OF WHICH IS SUCH THAT ITS FACES ARE TANGENT TO BOTTLE 4 TO BE PROTECTED, THE RIGHT PRISM BEING OBSTRUCTED AT LEAST PART AT ITS BASE BY A PART SUITABLE TO BE APPLIED AGAINST THE BOTTOM OF THE BOTTLE AND INCLUDING IN ADDITION TO ITS UPPER PART AT LEAST ONE ELEMENT SUITABLE TO TIGHTEN THE SHOULDER WHICH JOINS THE BOTTLE AND THE NECK OF THE BOTTLE. APPLICATION TO THE PACKAGING OF BOTTLES IN PACKAGING.

Description

The invention relates to a protective envelope for

  bottle, designed especially for the purpose of

lots of bottles.

  It is known that full bottles, whether glass or plastic, are generally delivered to consumers in cardboard cases, in which partitions or spacer elements separate the containers.

  different bottles to protect them from shocks.

  A particular problem arises when the bottles are delivered lying, in the head-to-tail position, in their packages, because the bottles of two superimposed layers are generally offset relative to each other, which complicates the separation between layers and leads to

  batches of bottles that are not stable in stacking.

  The invention aims to overcome this disadvantage by proposing to wrap the base of the bottles with a sheath, which protects them effectively from shocks and which thus replaces the usual intercalary elements of the packaging, which allows to superpose on each other without

  shift, the bottles of the different layers, reinforcing

  thus, the stacking resistance of the packages, which can be easily placed on the bottles, on the same bottling lines, without any significant change.

of these.

  For this purpose, the subject of the invention is a wavy corrugated envelope or the like for protecting the barrel

  of a bottle, characterized in that it has the general shape

  of a right prism, preferably regular, whose section is such that its faces are tangent at least to the surface of the barrel of the bottle to be protected, said right prism being closed at least partially at its base by a portion adapted to be applied against the bottom of the bottle and

  furthermore, at its upper part, at least one

  able to grip the shoulder that joins the barrel and the neck of the bottle or an element that has an opening in laQuelle can engage the neck of the bottle,

  which is thus prisoner of said envelope.

  -2- The parts enclosing said shoulder may be constituted by adjoining flaps at the upper part

  faces of the right prism and inclined to them.

  The section of said prism may be for example a square, a hexagon or a regular octagon. As will be seen in more detail with reference to

  the following description of many forms of implementation

  embodiment of the invention, the element or elements closing the base of the prism and the element or elements provided in the upper part thereof are held in a fixed position by against-gluing against flaps and or adjacent faces of the prism, the final assembly of the envelope being made on the same bottling line, the body of the prism being

or not pre-assembled.

  Another object of the invention is therefore constituted by a bottle whose barrel is housed in said envelope and

prisoner of it.

  The base of the bottles being equipped with a prismatic envelope, it is conceivable that it is easy to condition these bottles in a package, in the head-to-tail position, by superimposing several layers of bottles whose envelopes rest on top of each other. by their flat faces and laterally against the walls of the shipping crate,

  which ensures their rigging. In addition, super bottles

  of the different layers are supported on each other by a generatrix of their barrel, so that they contribute to the resistance to stacking of packaging, that

  it can thus be stacked on great heights.

  Another object of the invention is therefore constituted by a packaging containing bottles arranged head to tail and following several superimposed layers, this packaging being characterized in that the drums of said bottles are equipped with an envelope according to the invention and in what the bottles of the different layers support the

  on each other, without lateral shift, through the

  area of the flat faces of said envelopes.

  The accompanying drawings show various embodiments of the invention. In these drawings: Figures 1 and 2 are plan views of two blanks of cardboard, for the realization of an envelope according to the invention; Figure 3 is a perspective view of a bottle equipped with an envelope made from a blank according to Figure 1 or Figure 2; Figures 4 to 14 are plan views of other single-piece cardboard blanks for making envelopes according to the invention; Figures 15, 16 and 17 are exploded views showing the realization of envelopes according to the invention from two separate elements; FIG. 18 illustrates the filling of a packaging with several superposed layers of bottles, equipped with an envelope according to FIG. 1 and arranged on the back. Referring first to FIGS. 1 and 2, on which

  the same references designate identical parts.

  The body of the envelope consists of four

  identical ones, la, lb, lc and ld, made of corrugated cardboard,

  2. A shutter 3, adjacent to the panel 1a, is laminated during assembly against the inner face of the panel 1d, so that the four panels thus define a straight prism with a square section 1, which

  sheath shape for the barrel of a bottle 4 (Figure 3).

  At the top of the panels lb and ld is provided a trapezoldal flap, respectively 5b and 5d, while at the top of the panels la and lc is provided a flap

  identical, respectively 5a and 5e, but on which is

  side by a fold line a triangular flap

  connecting wire, respectively 6a, 6c, which, during assembly comes to be laminated on the inner face of the flap 5b, 5d adjacent. The flaps 5a, 5b, 5c, 5d are then in the inclined position that can be seen in FIG. 3, with respect to the adjoining panels, la to ld, and encloses 4-

  the shoulder that joins the barrel and neck of the bottle 4.

  At the base of the panels la to id are provided, in the case of Figure 1, flaps, respectively 7a to 7d, which, during assembly, are folded to 90, partially overlapping against the bottom of the bottle, and are laminated against each other. The bottle 4 is thus trapped in the envelope which equips it, the flaps have at 5d on the one hand, 7% on 7d, on the other hand, preventing it from moving in one direction or the other by report to

the envelope.

  Alternatively (Figure 2), instead of the flaps 7a to 7d, can be provided at the base of a panel # the panel lb for example, a square portion 8, of section equal to that of the prism 1, it thus closes at its base by forming a bottom, shutters 9a, 9c and 9d adjacent to the panel 8 coming respectively against the panels la, le, Jd,

against which they are stuck.

  As noted above, the envelope does not necessarily have the shape of a right square section prism, but its section may also be in the form of a regular polygon, including an even number of cations, for example a hexagon, as shown in FIG.

  found in this embodiment six recom-

  identical tangles, referenced 10a to 10f, hinged together by fold lines 11, one of which, the panel 10a, laterally comprises a flap 12, which is applied and stick against the inner face of the panel 10f, when of the assembly. All panels have at their base a flap, referenced 13a to 13f, which, during assembly, is folded to 900 relative to the adjacent panel They overlap and partially to be assembled by collages The panels c and 10f, which, in position mounted, are parallel to each other, Oomport to their upper part a trapezoidal flap, respectively 14c and 14f, while the panels lob and 10es comprise an identical flap, 14b and 14e, but have a lateral connection allowing, during assembly, -5 -. to make them integral by gluing in an inclined position,

  in flaps 10c and 10f also inclined.

  The fi lure 5 represents a blank making it possible to make a square-section envelope. On two parallel sides of a portion of the bottom 20, of square shape, are articulated two rectangular panels 21, which is erected perpendicular to the bottom 20 during assembly, to form two side walls of the right prism.A each of the panels 21 are adjacent laterally, by a fold line, panels 22, of width two times smaller, which, after mounting, each form half of another face of the right prism and come to be pressed against panels 23 articulated on the bottom 20

  and erect perpendicular to it. In the upper part

  the upper part of the panels 21 is provided a flap 24, having a notch of circular profile 25, intended to grip the shoulder of the bottle, when the flaps 24 are inclined against this shoulder and held in this position by laminating side flaps 26 against the

  corresponding side flaps of the opposite panel.

  Figure 6 shows another type of envelope to

  square section according to the invention. In an upper panel

  30 of square shape is formed a hole 31, in which is engaged the neck of the bottle. On two parallel sides of the square 30 are articulated two trapezoidal flaps 32 and

  on the other two sides are articulated two identical

  33, intended, like the flaps 32, to come to apply,

  in inclined position, against the shoulder of the bottle.

  On the longer side of the shutters 33 are hinged rectangular panels 34, intended to form two faces of the prism, the other two faces being each formed by two panels 35 adjacent respectively to the panels 34, but twice as wide as these , which are laminated against flaps 36 adjacent flaps 32. At the base of the panels 34 are provided flaps 37, each having two lateral extensions 38, to be laminated against adjacent extensions, to form the base of -6- 'envelope. FIG. 7 represents an alternative embodiment of the envelope of FIG. 2 and the elements already described therein

  retain the same reference figures, the only difference

  being that at the base of the panels 1a, 1c and 1d are provided flaps, respectively 39a, 39c and 39d, which

  come back against the bottom piece 8.

  FIGS. 8, 9 and 10 are partial views of other variants of FIGS. 1 and 2, where the elements already described

retain the same references.

  In FIG. 8, a square bottom piece 40 is articulated along one of its sides on the panel 1a, while it comprises, on its opposite side, a flap 41 intended to

  to come to apply against the inner face of the panel lc.

  Flaps 42 and 43, articulated respectively to the base of the panels lb and ld, are applied against the inner face of the bottom 40, to form therewith a case closure

of a classic type.

  FIG. 9 represents another variant in which the parts 45a, 45b, 45c and 45d, respectively adjacent to the base of the panels 1a-1d, have a shape known per se constituting a semiautomatically closed boot bottom. In a variant of FIG. 10, flaps 46a, 46b, 46c and 46d, respectively adjacent to the panels 5a, 1b, 1c and 1d, overlap each other and the flaps 46a and 46c comprise a tongue 47a, 47c which is folded over.

  and glued against the adjacent flap, respectively 46d, 46b.

  Figure 11 shows another type of sectional envelope

  square, comprising a square bottom 50, on which are

  crimped by fold lines of the identical rectangular panels 51 and 52, respectively, which are

  form the right prism. The panels 51 comprise, lateral-

  flaps 53, which come to stick against the inner face of the panels 52 and, at their upper part, flaps 54, which are applied in an inclined position against the shoulder of the bottle which they enclose the -7- collar by a circular notch 55. The flaps 54 are

  provided laterally with tongues 56 allowing them to

  dariser them by gluing said tabs.

  Figure 12 shows yet another type of square section envelope according to the invention. At two parallel sides of the bottom 60 are adjacent two rectangular panels 61 and 62, the latter itself being hinged laterally on two identical rectangular panels 63 having a flap 64 which is glued against the inner face of the panel 61. At the upper part panels 63 is provided a flap 65 intended to be applied in an inclined position against the shoulder of the bottle to be equipped, which it encloses

  by an indentation 66, lateral tabs 67 make it possible

  to secure the shutters 65 by gluing.

  Another variant with a square section is shown in FIG. 13. A square upper portion 70 caps the bottle whose neck is engaged in an opening 71. Two panels 72 are hinged on two parallel sides of the portion 70 and erected perpendicularly to that portion. and two faces of the right prism, while each of the two other faces of the prism is formed of two panels 73, laterally attached to the panels 72, but of width two times smaller than these. The panels 73 are glued on

  panels 74 adjacent to part 70. The base of the enve-

  loppe is defined by flaps 75 adjacent to the lower part of the panels 72 and extend laterally by tabs 76, which are adhered to the inner face

  73. It should be noted that in this form of

  invention, as in that illustrated in Figure 6, the upper part of the envelope is parallel to its base, in this case, there is no part

  slanted against the shoulder of the bottle.

  Figure 14 also represents another type of enve-

  square section loppe, comprising four rectangular panels

  adjacent walls, 80a, 8G7, 80c and 80d, the panel 80d having, along one of its long sides, a tongue 81, sticking in mounted position against the inner face of the panel 80a. The panels 80a and 80c each comprise, at one of their ends, a flap 82, intended to form the part of the bottom of the envelope after bonding the overlapping parts, and at the other end, a flap 83, presenting an indentation 84 for the passage of the shoulder of the bottle, against which they come to bear in inclined position, after gluing the legs 85 which they are éauipés. All the envelopes according to the invention which have been described so far come from a single blank of

  cardboard or corrugated cardboard properly cut and scored.

  These envelopes may, however, be made by assem-

  several distinct parts, as are the embodiments represented on the

Figures 15, 16 and 17.

  Thus, for example, * the envelope of the figure consists of two parts, one 86, in the form of

  square-section right prism with a bottom (not shown)

  the other 87 comprising a plare88 portion, parallel to the bottom of the portion 86 and pierced with an opening 89 for the

  passing the neck of a bottle, two side

  90 tapers conforming to the shape of the shoulder of the bottle, and two end flaps 91 coming to counter against

  the inner face of two opposite panels of the portion 86.

  With such an envelope, the bottle is first put in place in part 86, then capped by part 87, which

  is then glued against part 86.

  In the embodiment of FIG. 16, the lower part comprises a bottom 92, to which are attached two rectangular panels 93, provided with lateral flaps 94, and two flaps 95, on which two side panels 96 of the upper part are bonded. . The panels 96 are joined by two inclined portions 97 to a flat portion 98 parallel to the bottom, in which is pierced an opening 99

  for the passage of the neck of the bottle.

  The lower part of the envelope shown in FIG. 17 simply comprises a bottom 100 and two panels.

  rectangles 101, while the upper part

  takes a plane portion 102, parallel to the bottom and pierced with a hole 103 for the neck of the bottle, and two inclined lateral portions 104, extending by panels 105, which flaps 106 make it possible to join together by gluing.

  panels 101 of the lower part.

  As indicated above, the protective casings according to the invention have a particularly advantageous application in the packaging inside a package of several superposed layers.

  bottles arranged head to tail.

  Indeed, as can be seen in Figure 18, which represents

  Sense such a package 110, for example an American box open laterally, it is possible to rest on each other, by some of their flat faces, the envelopes 111, in which the bottles 112 are prisionnières. As a result, the lateral envelopes are thus wedged against the side walls of the body

  and that, if the right-hand prism part of the

  loppes is sufficiently long, that is to say greater than the material of the height of the bottles, the envelopes of the bottles in the head position have a part in contact

  and so lock each other up, forbidding any movement

  lateral cement during the handling of the crate. It should be noted, in this regard, that the bottles being trapped in their envelope, there is no risk of movement of the envelope by sliding along the bottle, during

handling operations.

  In addition, as can be seen clearly in FIG. 18, the bottles of the different layers are plumb with each other, and not laterally shifted from one layer to the other, as is usually the case. As a result, the bottles are supported on each other at their upper generatrix and their lower generator, so that they contribute to the resistance.

  crushing the full box, which is thus self-

  carrier. When stacking crates, it is possible to build piles of cases much larger than usual packages. As the volume of protective envelopes

  and their assembly around the bottles fit easily

  existing bottling lines, the invention

  Therefore, it provides a simple and inexpensive means for improving the packaging of batches of bottles in a package. Naturally, the envelopes according to the invention can also be used for packaging bottles standing in conventional packaging, the envelopes then replacing the usual braces or other separations known in the art. In this application, all the bottles can be dressed with an envelope according to the invention or only,

  alternatively, one in two of them.
