Definitions
- the present invention relates to a sealed window box which can be produced at least partially by forming and fixing a blank in a semi-rigid material such as cardboard or the like.
- boxes are known of cardboard, or similar semi-rigid material, which have a window closed by a film format of a transparent plastic material whose edges are fixed to the edges of the window and which allows see the item (s) packed in the box. It is easy by fusing the edges of the film to seal the window. However, the box is not completely sealed.
- the subject of the present invention is a waterproof box made of cardboard or similar semi-rigid material, the body or cover of which has a window.
- This box is characterized in that a transparent plastic film is fixed on the internal face of the body or of the cover of the box and / or of its cover, extending over the entire surface of this body or of this cover, so that it closes the window and makes it possible, by heat sealing, to obtain a perfectly sealed body or cover, so that the film which acts as a window simultaneously performs the role of bonding and eliminates the need for a supply of glue.
- the body of the box can be obtained from a blank, two opposite edges of which are joined to one another so as to obtain a tubular structure whose internal surface is coated with the above film.
- the film may protrude slightly from one of the two edges so as to constitute a tab which is fixed by theraio welding on a film area adjacent to the other edge. Thanks to this arrangement, an excellent seal is obtained at the junction of the two edges with insulation of the edge in semi-rigid material of the blank, with respect to the material contained in the box.
- the film may slightly protrude at least one of the opposite edges delimiting one of the two orifices of the tubular structure.
- this orifice can be closed by a cover, the peripheral edge of which comprises an annular cavity in which the said edge engages, on which the projecting part of the film has been folded down.
- This projecting part can then be fixed in this position both on the body and on the cover by heat sealing. There is thus obtained a very good quality waterproof fixing between the body and the cover.
- the above film can be used to produce a tamper-evident security closure of the cover with an integrity indicator.
- the cover is provided with at least one orifice or a notch and the portion of film covering this orifice or this notch is heat-sealed on the body or on an element integral with the body so that the opening of the cover implies a tearing and / or a visible tear of said portion.
- Figure 1 is a perspective view of the body of a box made according to a first embodiment of the invention
- Figure 2 is a sectional view of part of the wall of this body to the right of the window;
- Figure 3 is a perspective view of a box according to a second embodiment of the invention.
- Figure 4 is a perspective view of a box made according to a third embodiment of the invention.
- FIG. 5 shows the blank from which the box shown in Figure 4 is made
- Figure 6 is a schematic partial section showing the principle of closing the cover of the box shown in Figure 4 with integrity indicators;
- Figure 7 is a partial axial section of a box comprising a cylindrical body closed by a cover;
- Figure 8 is a partial schematic perspective view showing the sealed assembly of the body of the box shown in Figure 7;
- FIG. 9 is a partial axial section illustrating the principle of the sealed closure of the cover on the tubular body of FIG. 7.
- the box according to the invention comprises a body 1 whose section is rectangular.
- This body 1 is obtained by folding a blank consisting of a sheet of cardboard 2 from which has been cut an opening or window 3, for example rectangular; on the entire surface of this sheet was fixed a film 4 of a transparent heat-sealable plastic.
- the film 4 closes the opening 3; moreover, after folding the blank, so that the film 4 is inside, the two longitudinal edges of the blank can be fixed to one another by applying these two edges to each other and by fusing the film on one edge to the cardboard on the other edge.
- the body 1 can be closed by a bottom 5 provided with folded edges 6 and which is introduced into the body, at one of its ends, the edges 6 then being heat-sealed on the internal wall of the body.
- This bottom may include a window and sealable edges, themselves covered with the same film as the window.
- the other end of the body can be closed in a similar manner or by a cover fitted on the body and fixed on it. A box is thus obtained, the body of which is perfectly sealed over its entire surface, both at the right of the window 3 and at its junction with its bottom 5 and at the junction of its two longitudinal edges.
- the body 7 of the box has no window and is constituted by a simple cardboard plate and has at its upper part an outer peripheral flange 8.
- the body 7 is closed by a cover consisting of a cardboard plate 9 from which is cut a window 10 and which is lined by an inner film 11 of transparent plastic. This film closes the window 10 and when the box is closed, is heat sealed on the flange 8.
- the box comprises a tubular body 14 or sheath of parallelepipedal section closed on one side by a bottom (not visible) and, on the other side, by a hinged cover 15 d '' one side on the body 14 around a fold line 16 and extended on the other side by a tongue 17 which engages in the body 14 in the closed position of the cover 15.
- the front face 18 of the body 14 is provided with a diamond-shaped cutout D which constitutes a window through which the contents of the box can be observed.
- the cover 15 is provided with two lateral oblong bores 20, 21 which, as will be explained below, serve for the tamper-proof fixing of the cover 15 and also ensure the role of integrity indicators.
- the box is produced by folding and fixing a cardboard blank, one of the faces of which, which here corresponds to the outside face of the box, is completely covered with a film of heat-sealable transparent material 19.
- This film 19 therefore covers both the cutout D and the two oblong holes 20, 21.
- This blank comprises a rectangular longitudinal central strip divided by four transverse fold lines Pu to P, into five successive rectangular areas PL] to PL 5 , namely:
- a third area PL 3 intended to constitute the rear face of the box
- a fifth track PL 5 which constitutes a tab intended to be fixed on the free edge of the first track PL ! .
- the areas PL] to PL 4 are extended on one side by four respective flaps Ri to R 4 intended to constitute the bottom of the box, these flaps being connected to the areas PL] to PL 4 by corresponding fold lines.
- the pad PL Î is extended on the side opposite the flap R] by a pad PL 6 constituting the cover 15 then by a pad PL 7 constituting the tongue 17, the pads PL 15 PL 6 , PL 7 being connected to each other by fold lines P 5 , P 6 .
- the areas PL 2 and PL 4 are extended on the opposite side to the flaps R 2 , R 4 by two respective areas PL 8 , PL 9 constituting flaps 23, 24 on which the cover 15 comes to bear in the closed position.
- the locking of the cover 15 in the closed position is ensured by heat sealing the portions of the film 19 covering the oblong holes 20, 21 on the portions of film 19 covering the flaps 23, 24.
- the oblong shape of the holes 20, 21 having the advantage of '' ensure a perfect flatness of the cover which can no longer "yawn".
- the box has a body 25 of cylindrical shape, only one end has been shown, the other can be closed by a bottom according to a conventional technique or not.
- the inner wall of the body 25 which has an oblong window F is coated with a film of heat-sealable material 26 which protrudes slightly from the upper edge of the body 25 (projecting part 29).
- the body 25 is closed at this end by means of a cover C, the edge of which has an annular cavity 28 of substantially U-shaped section which extends axially and opens out at the bottom face of the cover C .
- This annular cavity 28 is intended to receive the upper edge 30 of the body 25 with the projecting part 29 of the film 26 turned outward so as to cover the edge T of the edge 30 and an adjacent area of the outer wall.
- the width of the cavity 28 is slightly greater than the sum of the thickness of the semi-rigid material constituting the body 25 and twice the thickness of the film 26.
- the body 25 is obtained from a strip of rectangular cardboard 31 covered by the transparent film 26 and whose two transverse edges B 15 B 2 are joined to one another and fixed in this position by heat sealing of the area of the film 26 lying between the two edges B 1? B.
- the film 26 projects slightly beyond the transverse edge to form a tongue 27 intended to be fixed by heat sealing in a zone of the film 26 adjacent to the edges Bi, B 2 in order to ensure a high seal at the junction of said edges. (figure 8).
- An important advantage of the solution described above consists in that the seal obtained by means of the cavity 28 of the cover and the projecting part 29 of the film 26 also covers the connection area of the edges B t and B 2 . Indeed, this area is trapped by the film 26.
- this solution makes it possible to guarantee sealing in the angular regions of the body in the case where the latter has a polygonal section. Indeed, in this case, we obtain a continuity of sealing at the edge of the body.
