Definitions
- containers In addition to rigid containers and those used in the industry for automatic packaging, containers can be divided into two main categories:
- the present invention relates to this second category.
- Examples include folding containers sold in post offices. They are delivered flat to the user and the latter must straighten walls or shutters (which is equivalent), maintain them and simultaneously set up the objects to be packaged because the container only becomes stable by its final closure.
- the present invention mainly remedies this drawback by making it possible to provide users, individuals or professionals, with a container which incorporates all that is necessary for its practical use, which makes any accessory useless, so that it is stable and fixed before the objects to be packed have to be placed.

- adheresive is used here when it is a substance which retains its properties for a relatively long time, especially when it is protected by a tape. It is, in fact, to defer the use of said adhesive after it has been placed, during manufacture.
- Such an adhesive is known per se and is sometimes defined by calling it an adhesive with "permanent setting time", which provides a "self-adhesive surface”.
- glue which concerns a substance which can only be used within a very short time, immediately after its installation, for a final fixation, before it has not hardened by drying, polymerization, evaporation of solvents and / or cooling.
- glue When glue is used for the manufacture of containers, it definitively assembles two parts of the blank from which the container is set in volume by the user, the latter therefore having no access to the glue, which is a means irreversible fixing.
- Fixing by irremovable means or those that leave indelible marks if they are removed is also considered irreversible, which is the case with staples, for example.
- the adhesive can be of any known type, in particular of the double-sided tape type, often designated by the expression "adhesive transfer tape" or else, for example, according to the provisions of European patent 431,144 in the name of the applicant.
- the invention relates to the packaging of objects in containers which are produced and then delivered in the form of a flat blank, having, as the case may be, one or more thicknesses, placing in volume of the blank to make a container being produced by the user (and not by the manufacturer).
- the container according to the invention can be presented in several forms depending on the phase of its cycle in which it is placed:
- a bowl or tray is formed, having a bottom 106 and four outer walls 107, 108, 109 and 110, the walls 107 and 108 being called “transverse” and the walls 109 and 110 being called “lateral”.
- the precut lines 102, 103, 104 and 105 determine four distinct elements 111, 112, 113 and 114, of quadrangular shape and exactly inscribed in the outline of the 'blank blank 101 and which, if they were not kept for reasons which will emerge from the description below, would constitute scrap to be eliminated in pure loss.
- Four pre-folding lines 115, 116, 117 and 118 placed diagonally determine for each separate element two triangular tabs 120-121, 122-123, 124-125 and 126-127.
- the long-acting adhesive 130 can be arranged in more or less extensive zones, in flat or dotted lines. and, therefore, in continuous or broken lines, straight, curved or broken.
- the adhesive lines are located substantially halfway up the separate elements and therefore cross the oblique pre-folding lines 115, 116, 117 and 118, which is of great interest, as will be explained below.
- the blank after manufacture, is determined by its external contour cut out from a plate and by the pre-folding lines 102, 103, 104, 105 and 115, 116, 117 and 118.
- the blank of FIG. 1 is therefore ready to be marketed and, to this end, the production is followed by a grouping of several blanks 101, of possible packaging, storage and delivery to the customer, that is to say to users.
- the user receives one or more blanks, possibly stores them and then takes them one by one to constitute as many containers.
- the separate elements 113 and 114 being integral with both a side wall and the transverse wall 108, the straightening of the walls 109 and 110 initiates the straightening of the transverse wall 108, so that the user does not that complete the straightening of this wall 108 by gripping and clamping the wall 108 and the triangular tabs 124 and 126.
- the adhesive 130 is broken down into two segments for each of the separate elements 113 and 114: one segment is on the triangular tab 124-126 and the other on the triangular tab 125-127.
- leg 124-126 is applied vertically (that is to say perpendicular to the pre-folding line 103) against the triangular leg located opposite 125-127, while the segment of this leg 125-127 s' applies horizontally (that is to say parallel to the pre-folding line 103) against the triangular tab situated opposite 124-126 (see FIG. 2).
- the user completes the assembly by pinching the wall 108 and the triangular tabs 124 and 126 between two fingers.
- the user can then use both hands to place the objects to be packaged on the base 106.
- This completion consists in removing the protective tape 131 from the separate elements 111 and 112, then pinching between two fingers the transverse wall 107 and the triangular tabs 121 and 123, after this wall 107 has been completely raised according to arrow F3.
- the user then has a complete container, without lid, of the type known by various names: tray, tray, bowl, crate, crate and others.
- a cover or a lid can be left uncovered or be protected by a cover or a lid.
- some fruits are only protected by a simple light sheet of paper or by a plastic film, sometimes perforated, to allow the ventilation of the contents, while others must be enclosed by means of a rigid cover, as will described later.
- FIGS. 1 and 2 The container of FIGS. 1 and 2 is very simple and requires only elementary and inexpensive operations for its manufacture.
- the blank 101 delivered is relatively bulky because it has only one thickness, without overlapping, and, as a consequence, has a fairly large width, equal to the sum of the widths of the wall 109, of the base 106 and of the wall 110.
- FIGS. 3 to 6 differs from the previous one by an additional connection, produced during manufacture, between the transverse walls and the separate elements, which has, moreover, the advantage to make the blank delivered narrower.
- Figure 3 we see a blank corresponding exactly in shape and size to the blank of Figure 1, because both are intended to obtain a container of the same design and the same capacity.
- the triangular tabs 120, 122, 125 and 127 receive, during manufacture, glue represented by a dotted sowing and which, here, is provided over the entire surface of the triangular tab but which, of course, could also be arranged in the form of one or more one-off or online deposits.
- this glue should not be confused with the long-acting adhesive 130. It should be used immediately after it has been placed in its place.
- this adhesive must irreversibly join each of the two transverse walls 107 and 108 with the adjacent triangular legs, namely the wall 107 with the legs 120 and 122, and the wall 108 with the legs 125 and 127, which is obtained, during of manufacture, by folding over the transverse walls 107, 108 and the base 106, on the one hand the wall assembly 109 and separate elements 111 and 113 along the pre-folding line 104, and on the other hand the wall assembly 110 and separate elements 112 and 114 along the pre-folding line 105 (FIG. 4).
- the blank of Figure 3 is therefore only an intermediary between its cutting and its preparation of blank ready for delivery, as shown in Figure 4.
- This blank is narrower than that of Figure 1 , that is to say less bulky and if it has a double thickness due to the superposition of two lateral parts on the central part, this is not a significant drawback with regard to the advantages it has for its delivery and for its assembly by the user.
- FIG. 5 illustrates the setting in volume of the blank which, here, begins not with the straightening of the side walls 109, 110 and that of the transverse wall 108, but by the lifting of the side walls 109 and 110 according to the arrows F4.
- the separate elements 111, 112, 113 and 114 being integral with the adjacent transverse and lateral walls and the triangular tabs 120, 122, 125 and 127 being fixed (as soon as they are made) to the transverse walls 107 and 108, the lifting of the lateral walls 109 and 110 has the effect of automatically straightening the walls 107 and 108 and force the separate elements to bend along the oblique pre-folding lines 115, 116, 117 and 118.
- the user removes the protective tape 131 from the separate components 113 and 114, before or after having lifted the side walls 109 and 110.
- FIG. 6 the position of the container is seen after straightening and fixing of the side walls 109, 110 and of the transverse wall 108.
- the legs 124, 125 and 126, 127 form with the wall 108 a fixed and inseparable assembly, the legs 125 and 127 being glued to the wall 108 and the legs 124 and 126 being fixed to the legs 125 and 127 by the adhesive 130.
- the transverse wall 107 is shown in the position it occupies when it has been partially straightened, automatically, under the pulling effect exerted by the separate elements 111 and 112, themselves pulled by the raised side walls 109 and 110 by the user.
- the protective tape 131 has been removed and the user only has to pinch the wall 107 and the triangular tabs 121 and 123 to have a finished container.
- the objects to be packaged can be placed on the base 106, either before or after having fixed the wall 107 and the legs 121 and 123.
- the container according to the invention may have an integrated cover, as will now be described with reference to FIGS. 7 to 19.
- FIG. 7 shows a blank similar to that of Figure 3.
- the transverse wall 107 is secured to a closure panel 140 by a pre-folding line 141 and this panel 140 is itself secured to a so-called "fixing flap "142 by a pre-folding line 143.
- the closure panel 140 has two so-called" locking "tabs 144 and 145, differentiated from the panel 140 by pre-folding lines 146 and 147.
- the side walls 109 and 110 are secured by pre-folding lines 148 and 149 of flaps 150 and 151 marked with precut lines 152 and 153.
- the triangular tabs 120, 122, 125 and 127 receive glue, as already indicated with regard to FIG. 3.
- Long-lasting adhesive 130 covered with a protective tape 131 is placed on the hidden face of the blank of FIG. 7 and extends transversely, in a single line, from one edge to the other of the blank, crossing the oblique pre-folding lines 117 and 118.
- two glue dots 154 and 155 are placed on the closure panel 140 opposite the tabs 144 and 145.
- the adhesive must irreversibly join each of the two transverse walls 107 and 108 with the adjacent triangular legs, namely the wall 107 with the legs 120 and 122, and the wall 108 with the legs 125 and 127, which is obtained, during manufacture, by folding over the transverse walls 107, 108 and the base 106, on the one hand the wall assembly 109 and separate elements 111 and 113 along the pre-folding line 104, and on the other hand the wall assembly 110 and separate elements 112 and 114 along the pre-folding line 105 ( Figure 8).
- the locking tabs 144 and 145 are also folded along the pre-folding lines 146 and 147 and they are fixed to the panel 140, inside its outline, by means of the glue dots 154 and 155.
- the blank of FIG. 7 is therefore only an intermediary between its cutting and its preparation of blank ready for delivery, as shown in FIG. 8.
- the user When using the blank of FIG. 8, the user performs the same operations as those described with the previous embodiment, with reference to FIGS. 3 to 6 and, in addition, he straightens the locking tabs 144 and 145 , which is possible because the glue dots 154 and 155 are of small extent and / or made of a substance having, by design, a low coefficient of adhesion.
- the locking tabs 144 and 145 are simply peeled off and they are only put in the active position when the container is closed, which is described below.
- the user lifts the side walls 109 and 110 according to the arrows F4, which puts the blank in the situation mentioned in FIG. 9. It removes the protective tape 131 from the ends of this tape located near the edges of the triangular tabs 124 and 126, this tape remaining in place over its entire length located on the outside of the transverse wall 108 thanks to the fact that, when of manufacture, this ribbon is cut transversely to itself in line with the pre-folding lines 104 and 105 which form the delimitation between the wall 108 and the triangular tabs 125 on the one hand and 127 on the other hand.
- the user can fix, by the adhesive 130 uncovered, the legs 124 and 126 to the legs 125 and 127 glued to the wall 108 during manufacture, an operation which is evoked by FIG. 10.
- this single operation makes it possible to make the part of the container formed by the base 106, the transverse wall 108 and the side walls 109 and 110 perfectly stable and fixed, by means of the separate elements 113 and 114.
- the user can then place the objects to be packaged on the base 106 using his two hands.
- the user When the objects to be packaged are installed, the user lowers the flaps 150 and 151 inwards, which releases the cardboard parts cut by the pre-cut lines 152 and 153, these parts determining two ribs 156 and 157 which are protruding above the flaps 150 and 151 because these parts remain in the extension of the side walls 109 and 110 instead of folding with the flaps 150 and 151.
- the lowering of the flaps 150 and 151 unmask two slots 158 and 159 whose width is coordinated with the thickness of the cardboard so that a tab 144-145 can penetrate there.
- the ribs 156 and 157 can be removed if they are not used, for example to cooperate with the closure panel 140.
- they are useful during manufacture because they create the slots 158 and 159 which are needed, while avoiding the delicate operation of removing and eliminating the cardboard cut on the four sides of each slot.
- the user completes the closure of the container by applying the fixing flap 142 against the transverse wall 108 to which it is permanently fixed by the adhesive 130 which was unmasked during the removal of the tape.
- the finished container constitutes a box, the manufacture of which is simple and inexpensive because it involves processes and means accessible to those skilled in the art.
- the blanks are delivered flat and occupy a small volume for shipping and storage.
- the setting up of a blank to mount it in a container is extremely simplified compared to known comparable models, and it does not require any mounting or closing accessory. This makes it a particularly well-suited box for the general public and, in particular, for postal items.
- the presence of the legs 144 and 145 removes, between the top of the side walls 109-110 and the closure panel 140, any space through which could, voluntarily or accidentally, pass a thin object such as an envelope, a postcard, a sheet or the like, both from the inside to the outside and vice versa from the outside to the inside. This guarantees both the integrity of the content and the security of documents and of postal mail in general, capable of rubbing shoulders with a closed box in accordance with the invention.
- the closed box is inviolable, even by fraudulent practices, because when the adhesive 130 of the fixing flap 142 has been unmasked and then applied against the wall 108, it is impossible to open the box and access the content other than by destroying an external part, which immediately reveals the fraud and prevents it from being practiced secretly.
- the height of the fixing flap 142 must simply be sufficient for it to cover the wall 108 up to the level of the adhesive 130 and, for safety, a little below.
- the fixing flap 142, the closure panel 140 and even the transverse wall 107 are subjected to a force which tends to return these components to their original position, flat, since they are brought to their position. final by constraining the carton along the pre-folding lines 102, 141 and 143.
- the pressure action exerted by the user when the box is closed causes a correlative reaction of the wall 108 and, as this wall 108 is flexible, its resistance to deformation depends on the rigidity of the structure, which is maximum on the pre-folding line 103 and decreases as it moves away from it, because this line determines two perpendicular planes (base 106 and wall 108) and is equivalent to a stiffening rib.
- the slot 108a is located below the adhesive 130 and above the lower edge of the transverse wall 108, because the fixing flap 142 is lower than the transverse wall 108.
- the blank of FIG. 20 receives glue not only on the triangular tabs 120, 122, 125 and 127 but also on two lateral strips 160 and 161 located beyond the lateral edges of the base 106, which widens by both the blank, both at the base of the side walls 109 and 110 and along the triangular legs 120, 122, 125 and 127.
- the diagonal lines 115, 116, 117 and 118 are identical to those of the previous embodiments, that is to say that they always end at the base of the side walls 109 and 110.
- Pre-folding lines 162 and 163 border these strips 160 and 161 and form a separation between the side walls 109-110 and these strips 160-161.
- Lines 162 and 163 therefore end at diagonal lines 115, 116, 117 and 118.
- the blank is ready for use, during manufacture, by folding over the transverse walls 107, 108 and the base 106, on the one hand the wall assembly 109 , separate elements 111 and 113 and side strip 160 along the pre-folding line 104, and on the other hand the wall assembly 110, separate elements 112 and 114 and side strip 161 along the pre-folding line 105 (FIG. 21 ).
- the side walls 109 and 110 are thus protected on three sides. It is therefore advantageous to complete this protection by the fourth side, that is to say by the closure panel 140.
- closure panel 140 is widened by two strips 167 and 168 which are glued against it during the folding of the blank of FIG. 20 to obtain the blank of FIG. 21.
- the strips 167 and 168, just like the reinforcements 173 to 176 can of course be fixed irreversibly to the panel 140 other than by glue placed according to the drawing in FIG. 20 (by staples in particular), or else the glue can be placed other than on flat surfaces (solid and continuous surfaces), for example: points, dots, lines, etc.
- the locking tabs 144 and 145 they must not be fixed irreversibly since they must be straightened out of their plane. For this, it is possible to plan to deposit a point of glue of the same quality as that of the strips 167 and 168 because the glued surface is so small that it can easily be removed without damage. But we can also create "bridges” or "attachment points” when cutting the blank, that is to say small fractions of cardboard 177 not cut when cutting the lines which give the outline of the legs 144 and 145 and isolate them from the reinforcements 173, 174, 175 and 176, and joining the two sides of the slots coming from this cutout.
- the locking tabs 144 and 145 can be given the same width as the walls 109 and 110, without wasting cardboard, as indicated by lines x and y . in dashed line.
- the legs 144 and 145 therefore extend over the entire height of the side walls 5 109 and 110 and bear on the base 106.
- the triangular legs 121 and 123 are somewhat spaced from the neighboring triangular legs 120 and 122, which leaves the pre-folding line 141 offset backwards along which the closure panel 140 is articulated to the transverse wall 107.
- the user By bringing the panel 140 forward, the user does not necessarily tighten the triangular tabs 120 and 122 towards the corresponding triangular tabs 121 and 123, so that the free ends 144a . and 145a . yz - tabs 144 and 145 do not necessarily appear in the middle of the length of the slots 158 and 159.
- the longitudinal axis of the legs 144 and 145 is parallel to the vertical edges of the walls and perpendicular to the plane of the base
- the folding down of the panel 140 takes place not along a straight line but along a curve which is the result of the pivoting of the wall 107 around the pre-folding line 102 and the pivoting of the panel 140 around the pre-folding line 141. Thanks to the support of the edges 144b. and 145b against the edges of the ends 158b and 159b of the slots 158 and 159, the simple action of folding the panel 140 over the packaged objects automatically causes the wall 107 to pivot and the triangular tabs 121 and 123 to fold since the edges 144b . and 145b push on the ends 158b and 159b because the legs 144 and 145 cannot be lowered without simultaneously forcing any point whatsoever of their edges 144b and 145b to remain in contact with the ends 158b and 159b.
- edges 144b and 145b which are situated at the ends 158b and 159b of the slots 158 and 159.
- the front edges 144e. and 145th . are advantageously curved, to penetrate without gene near the front ends 158a. and 159a . .
- edges 165 and 166 The existence of the edges 165 and 166 has the consequence that the triangular tabs 120-122 and 125-127 have an exposed part which vertically extends the corresponding edge 165-166, which is very advantageous.
- the triangular tabs 125 and 127 receive extended-effect adhesive 130 over their entire width, so that if this adhesive 130 were disposed as described with the embodiment of FIGS. 7 to 19, removing the protective tape 131 at this point, would leave the adhesive 130 exposed, accessible to all dust and impurities and presenting the danger of retaining objects located near the closed box, without even mentioning the inconvenience for the user involuntarily placing their fingers on this adhesive.
- This removal consists in cutting the cardboard from the blank, but obviously after placing the adhesive and protective tape 131, according to a window 181 which constitutes the desired neutral zone.
- the embodiments described above always provide for the direct retention of the triangular legs 125 and 127 (as well as possibly the triangular legs 120 and 122) against the wall 108 (as well as possibly against the wall 107) with glue. and holding the corresponding triangular tabs 121-123 and 124-126 by extended-effect adhesive 130 which joins them together without an intermediary.
- Figures 32 to 40 provides for the maintenance of the triangular legs, and therefore separate elements 113 and 114 (and possibly 111 and 112) as a whole by different means, so that the separate elements are maintained indirectly.
- the same parts bear the same references as in the preceding figures and their description and their usefulness will only be repeated if this is useful for the proper understanding of the drawings.
- the blank in FIG. 32 has two so-called "blocking" flaps 184 and 185 secured to the transverse wall 108 by pre-folding lines 186 and 187 and each carrying a segment of adhesive 130 and protective tape 131.
- the triangular tabs 125 and 127 do not receive adhesive 130.
- the locking flaps 184 and 185 remain in their position and, therefore, exceed the outline of the blank.
- the flaps 184 and 185 can be folded back inside the outline of the blank, by folding against the inside face of the transverse wall 108, in order to be protected from accidental catching.
- the container When the container is placed in volume (FIG. 34) the user lifts the side walls 109 and 110 according to the arrows F4, then straightens the transverse wall 108 according to the arrow F2. In doing so, the separate elements 113 and 114 fold, their triangular legs 124-125 and 126-127 bending against each other and against the wall 108.
- the user folds the flaps 184 and 185 inwards according to the arrows F6, after having removed the protective tape 131 from each of these two flaps (preferably before even lifting the side walls 109 and 110).
- the flaps 184 and 185 block all of the separate elements 113 and
- This embodiment also illustrates a variant concerning the locking tabs 144 and 145, a variant which is, of course, usable independently of the embodiment chosen for the other components of the container.
- the user After having set in volume and joined the side walls 109, 110 and the transverse wall 108, the user removes the protective tape 131 located on the fixing flap 142, straightens the locking tabs 144 and 145 then brings back the closure panel 140 forward, in now the legs 144 and 145 on the outside and against the walls 109 and 110.
- the fixing flap 142 By applying the fixing flap 142 to the wall 108, the user simultaneously tightens the separate elements 111 and 112, and the tabs 188 and 189 are automatically opposite the slots 190 and 191.
- the legs 144 and 145 are held in position where they double the resistance of the side walls 109 and 110. At the place where its slots 190 and 191 are to be found, there are two thicknesses of cardboard: that of the side edge 165- 166 and that of base 106.
- the tongue 188-189 can be given a height equal to that of the two thicknesses of cardboard and a second slot 190a respectively . and 191a in the bottom 106 proper (FIG. 32), so that after being put in place, the tongue 188-189 crosses both the lateral edge 165-166 and the bottom 106 (FIG. 38).
- tab 145 placed outside the side wall 110 and provided with a lower tab 189.
- a second tab 189a is provided . secured to the side of tab 145 in front be perpendicular to the bottom 106 of the upright container.
- This tongue 189a is blocked by the edges of a slot 191b formed in the triangular tab 122 and, possibly in the transverse wall 107.
- the tongue 189a automatically places itself in slot 191b . when the container is closed.
- a tab 145 is shown which is less high than the side wall 110, so that it does not have a lower tongue which could not reach the level of the side edge 166.
- FIG. 32 there is shown the case where the adhesive 130 and a protective tape 131 are deposited in a segment of a certain length, but it can also be a simple punctual deposit.
- the adhesive 130 and the protective tape 131 are provided inside the tabs 144 and 145
- FIGS. 33 to 36 the adhesive 130 and the protective tape 131 are provided in the outside walls 109 and 110.
- the locking tabs 144-145 placed outside the walls. side 109-110 and associated with different holding means.
- the structure of the box and the use of a long-acting adhesive make it possible to obtain a tamper-evident closure.
- the user grasps one or the other of the two tabs 196 or 197 and makes the gesture of tearing it off, which has the effect of exerting a strong pull on the link 195 which is too robust to break, follows the tongue to which it is securely attached and cuts in a straight line the cardboard sheet constituting the shutter 142.
- the adhesive 130 always brings together (since it is an irreversible connection) the fixing flap 142 and the transverse wall 108 but since the flap 142 is cut by the opening link 195, this amounts to removing the fixing flap 142 and the user can easily disassemble the box.
- FIGS. 41 to 48 another embodiment of the invention is shown, making it possible to obtain a very simple container and of reasonable cost price.
- FIG. 41 represents a blank on which there are always the same elements making it possible first to form a stable part of the container: the bottom 106, two transverse walls 107 and 108 and two side walls 109 and 110, as well as the separate elements 113 and 114 which will not be re-described.
- the closure panel 140 is secured to two side tabs 201 and 202 whose dimensions are substantially the same as those of the side walls 109 and 110, and the fixing flap 142 has substantially the same dimensions as those of the transverse wall. 108.
- This flap 142 is integral with two lateral tabs 203 and 204 determined by fold lines 205 and 206, and also has two 45 ° oblique fold lines, 207 and 208.
- the fixing flap 142 is folded along lines 207 and 208 (left part of FIG. 42), which shows two triangular fractions 209 and 210 of the fixing flap 142. Then, the assembly 201, 109, 113 is folded towards the center on one side and 202, 110, 114 on the other.
- This operation is still to be performed on the left side of FIG. 42 and is already accomplished on the right side.
- the lateral tabs 203 and 204 are glued to the upper part 201a-202a .
- the protective tapes 131 are removed from the two separate elements 113 and 114, then the transverse wall 108 is straightened towards the center according to arrow F2, while the two are straightened by spreading them apart according to arrows F4.
- side walls 109 and 110 which automatically brings the triangular tabs 124 and 126 against the triangular tabs 125 and 127 glued to the wall 108, to which they are fixed by means of the adhesive 130 unmasked, which is comforted by tightening between the fingers the legs 124-126 and the wall 108.
- the protective tape 131 is removed from the wall 108 to unmask the adhesive 130, then the side tabs 201 and 202 are moved aside, which pulls the fixing flap 142 in the direction of its straightening. , and rotate the triangular fractions 209 and 210 along the lines 207 and 208, to bring the flap 142 and its fractions 209 and 210 substantially in the same plane.
- This wall 107 is straightened and the side tabs 201 and 202 are kept apart so as to lead them outside the side walls 109 and 110, and finally the flap 142 is passed in front of the wall 108 until the cover styling covers this wall 108 and the side walls 109 and 110 (Figure 45).
- the external face of the flap 142 is pressed to apply its internal face 142b to the adhesive 130.
- two slots (at least 5) 211 and 212 are provided which pass through the thickness of the flap 142 at the level which corresponds to that of the adhesive 130 deposited. on the outer face 148a.
- a short segment of adhesive 130 and of tape 131 can be applied to each of the two distinct elements 113 and 114 after folding the blank, in the longitudinal direction. and no longer transverse, so that these segments always cross the fold line 117-118 and extend on the two triangular legs 124-125 and 126-127.
- Figure 50 we see that we take advantage of the adhesive deposit on the separate elements 113 and 114 to extend this deposit on the side walls 109 and 110, which allows, after removing the protective tape 131, d on the one hand to partially erect the container (wall 108 and side walls 109-110) and on the other hand when closing, to fix the locking tabs 144 and 145 outside and against the walls 109 and 110.
- the container is particularly solid and rigid. There is therefore a choice, having the adhesive longitudinally when making the blanks, between the three solutions of Figures 49 (separate elements 113 and 114 only), 50 (separate elements 113 and 114 and walls 109 and 110) , 51-52 (separate elements 113 and 114, walls 109 and 110, separate elements 111 and 112).
- This closure can be obtained in two different ways, depending on whether one still wishes to use adhesive 130 or not.
- the fixing of the flap 142 can be provided with the only two segments of adhesive 130 and of protective tape 131 situated in the extension of the two longitudinal segments, but it can also be supplemented by at least one other segment, such as that which is visible on Figures 51 and 52, substantially in the axis of the container.
- the second way is to provide a closing tab 220, of known type, secured to the free edge of the fixing flap 142 and to be introduced into a slot 221 formed in the transverse wall 108.
- the closure is carried out as described above with reference to the tongue 142a . and at slot 108a . , this being equivalent to the slot 221.
- the tongue 220 is therefore advantageously provided with two opposite teeth 222 and 223 which are folded flat on the tongue 220 before introducing everything into the slot 221, the fact of loosening the bending of the teeth 222 and 223, causing the return of the latter to their original position but after passing through the cardboard through the slot 221, against the inner face of the wall 108.
- the flaps 184 and 185 hold on to the blank by the pre-folding lines 186 and 187, but the same result could also be obtained by using an additional separate element, independent of the blank.
- the plate 300 When the plate 300 is given a surface corresponding to that of the transverse wall 108, it is placed inside the box, against the folded triangular tabs 124 and 126 to which the plate 300 is fixed by the adhesive to extended effect 130.
- the plate 300 need not also be fixed to the transverse wall 108 since it is sufficient for it to join the two triangular tabs 124 and 126.
- the joining of these two legs has the effect of keeping the walls 109 and 110 upright because the plate 300 prevents them from moving apart, which also prevents the triangular legs 124 and 126 from moving away from the wall 108, so that the presence of the adhesive 130 between the triangular tabs is superfluous.
- the blanks are provided on the one hand and the separate elements on the other hand, they are grouped into two different stocks, so that at the time of packaging, the user gathers them to create an assembly conforming to the invention, the blanks and the separate elements then forming an inseparable whole since the separate elements are fixed irreversibly to the blanks.
- the plates 300 can receive long-acting adhesive either longitudinally (FIGS. 54 and 55) or transversely (FIG. 56) and, after manufacture, the plates 300 are assembled in a stock like that illustrated in FIG. 55, then delivered to customers with or independently of the blanks themselves.
- the production of a separate element in the form of a plate 300 makes it possible to apply the invention to containers with variable height, whereby this height can be adjusted to that of the objects to be packaged, so that they are wrapped in closer to be properly maintained, immobilized and protected.
- FIGS. 57 to 64 there is shown the example of a very simple variable height container, the blank of which (FIG. 57) is an exactly rectangular band 301 which does not create any fall when it is cut from a plate, provided that the dimensions of the strip and the plate are suitably coordinated.
- the strip 301 is marked with two transverse precut lines 302 and 303 on either side of a central pre-folding line 304 and between two pre-folding lines 305 and 306, which determines an end panel 307.
- the end panel 307 is marked with two lateral longitudinal pre-folding lines 308 and 309 and a central longitudinal pre-cutting line 310 in the general shape of a very elongated S, which joins the middle of the pre-folding line 304 and the center d a notch 311.
- long-acting adhesive 130 is placed transversely and covered with a protective tape 131.
- two symmetrical lines of perforations 313 are cut during manufacture, arranged transversely and at the two ends of which two V-shaped cuts have been made which determine two small tongues 314 and 315.
- the blank of FIG. 57 receives glue on two lateral bands 316 and 317 intended to receive the margins of the panel 307 comprised between the longitudinal edges of the band 301 and the pre-folding lines 308 and 309, by folding the panel 307 along the lines 302-303-304-305-306, which makes the blank of Figure 42, the blank ready for use of Figure 58.
- two side edges 318 and 319 of width L corresponding to the edges 165 and 166 of the embodiments of FIGS. 20 to 40.
- the pre-folding and precut lines 308, 309 and 310 of the panel 307 give rise to two transverse flaps 320 and 321 articulated at the edges 318 and 319 and separated from each other, during packaging, by the line of central precut 310.
- two "bridges" 322 are provided, similar to those 177 of the embodiment of FIGS. 20 to 31.
- the user straightens the transverse flaps 320 and 321 and breaks the bridges 322 by using the notch 311 to slide his fingers under the flaps 320 and 321, which releases a base 323 intended for the objects to be packaged, constituted by the part of the strip 301 which extends from the lines 302 to 306 over a length equal to that of the edges 318-319.
- the width of the base 323 is equal to the distance between the pre-folding lines 308 and 309.
- the flaps 320 and 321 automatically fold at the height of the top of the objects to be packaged, forming an upper part 324-325 substantially parallel to the plane of the base 323 and a lateral part 326-327 either perpendicular to said plane, or more or less inclined. depending on the width of the objects to be packed. Only the upper parts 324 and 325 must be fixed to the separate element 300, but these parts are more or less distant from each other depending on whether the objects to be packaged are more or less high since the length of the flaps 320 and 321 being finished, it is divided into upper part 324-325 and lateral part 326-327 according to the height and the width of the objects to be packaged, these measurements being by hypothesis variable.
- the separate element 300 tends to eliminate the possible difficulties arising from unforeseeable differences in the dimensions of the objects to be packaged, since it makes it possible to join the two upper parts 324 and 325, and therefore the two whole flaps 320 and 321, whatever the spacing of the edges opposite the upper parts 324 and 325. It follows from these considerations that the separate element 300 can be more or less long depending on the height of the objects to be packaged and more or less short depending on the length of these same objects (it is indeed length, although the latter is measured according to the width of the strip 301).
- FIGS. 59, 61 and 62 show a large object to be packaged A and a small separate element 300, while in FIG. 60, a small object to be packaged B and a large separate element 300 are shown, in fact of the same dimensions as those of the base 323.
- two oblong windows 328 and 329 are cut out during manufacture from the carton constituting the flaps 320 and 321, in order to allow the 'user apply a finger on the element 300 through the windows 328 and 329 and slide it, if necessary, to its correct position.
- the user After having folded down the two flaps 320 and 321 on the separate element 300 (FIG. 62), the user has both hands to complete the container, that is to say to remove the protective tape 131 located at the end 312 of the strip 301 and then to bring back over the flaps 320 and 321 and the objects to be packaged, according to the arrows F9, the part of the strip 301 situated beyond the base 323, to its end 312.
- This part automatically folds along the first transverse edge 330 of the flaps 320 and 321, then along the second transverse edge 331 of these same flaps, then finally along the edge 332 corresponding to the fold line of the end panel 307 on the strip 301.
- the user thus achieves a complete wrap by closing the strip 301 on itself, and immobilizes the whole by applying the end of the strip 301 against the external face of the base 323 (FIGS. 63 and 64), the adhesive 130 close of the end 312, previously unmasked, irreversibly joining the strip 301 and the base 323.
- the finished container (figure 64) can receive a label to be sent by post.
- the recipient opens the container to remove the wrapped objects, by grasping one or the other of the two tabs 314 or 315 and gestures to tear it off, which has the effect of exerting a strong pull on the fraction of cardboard located between the two lines of perforations 313 which yield in series and thus create a cut in a straight line which releases the strip 301 since its end 312 fixed to the outside of the container remains only integral with the base 323.
- Figures 65 to 74 we see an embodiment of the invention among many other possible, according to which the separate element is integral with the blank.
- the blank comprises two parallel strips 401 and 402 joined by a pre-folding line 403 with a tab 404 determined in the strip 401 by this line 404, a second pre-folding line 405 and two cutting lines 406 and 407, the latter being oriented at 45 ° relative to the axis of the strip 401.
- This strip 401 is, here, longer than the strip 402, but in practice, according to the proportions which it is desired to give to the blank in order to make it compatible with a certain maximum length of the objects to be packaged, the bands 401 and 402 can be equal or unequal, one or the other being the longest.
- the cardboard of the strip 401 is longer than that which is only necessary to form side flaps, the separate element 400 being constituted, with this embodiment, by this excess of length, so that the it is possible not only to deposit therein long-lasting adhesive 130 and its protective tape 131, but that in addition the two ends of the strip 401 can be superimposed, as will be seen a little later.
- the strip 401 is marked with two pre-folding lines 408 and 409 which determine between them a central base for receiving the objects.
- the rule to follow to determine the length of the strip 401 is that it must be equal to twice the distance between the two lines 408 and 409, plus a more or less important length which is that intended to constitute the separate element. 400 ensuring the fixing between them of the two ends of the strip 401 over the objects to be packaged.
- the strip 402 is also marked with two pre-folding lines 410 and 411, but offset from the lines 408 and 409, which are only useful if the blank is made of corrugated cardboard, the grooves of the latter are longitudinal with reference to the band 402.
- the two strips 401 and 402 receive adhesive 130 along two lines located in the extension of one another. In fact, they are only one and the same line arranged at one time and cut transversely at the same time as the cutting lines 412 and 413 are created, on either side of the pre-folding line 403, which determine the two bands 401 and 402.
- the pre-folding lines 408 and 409 determine between them a base 414 for receiving the objects to be packaged.
- the pre-folding lines 408 and 409 determine between them and the transverse edges 415 and 416 two flaps 417 and 418.
- the very simple blank of Figure 65 is delivered either in the position of this figure, or after superimposition of the bands 401 and 402 by direct track along the line 403, so that this blank constitutes the finished blank, ready for use. .
- the two strips 401 and 402 are then equivalent to a blank of the same type as that described with reference to FIG. 58, that is to say a blank ready to constitute a container with variable height formed by a strip and flaps lateral.
- the user straightens the flaps 417 and 418 which fold along the pre-folding lines 408 and 409 which are spaced apart, it will be recalled, by a distance less than the width of the strip 402 (FIG. 69).
- the determination of the separate element 400 ultimately depends on the respective dimensions of the flaps 417 and 418 because they must be joined together regardless of the length and height of the objects to be packaged.
- the longest flap 417 must not have a length greater than the width of the strip 402 in order to be able to be applied to an object to be packaged of low height, or even almost zero. But it must have a sufficient length, as well as the flap 418, so that these two flaps can be fixed to each other by the adhesive 130, even if the objects to be packaged are thick (FIG. 71).
- the user completes the container by folding the upper part (in the drawing) of the strip 402 over the separate element 400 formed by the cooperation of the two flaps 417 and 418 (FIG. 72) then the lower part (in the drawing ) of the strip 402, after removing the protective tape 131 (FIG. 73).
- the container is finished when the user firmly applies the end of the strip 402 so that the adhesive 130 is fixed on the other end of the same strip 402 ( Figures 73 and 74).
