Abstract
Description
Title of the invention: Reusable packaging Technical field of the invention
[0001] The present invention relates generally to paper or cardboard packaging.
[0002] It relates more particularly to a device comprising packaging which is made from at least one blank in cardboard or paper and which includes an article receiving part and a closing part adapted to close the article receiving part.
[0003] The invention finds a particularly advantageous application in the manufacture of envelopes, boxes... State of the art
[0004] Packaging, whether in the form of a box or an envelope, has a part designed to receive items such as letters or objects, and a closing part for sealing the packaging. This closing part may, for example, be in the form of a simple flap, a lid, etc.
[0005] It is known to reseal the packaging in a tamper-evident manner, for example by applying dots of glue to the sealing part. Thus, the only way to open the packaging will be to tear it open.
[0006] Closure systems are also known that allow the packaging to be opened and resealed multiple times, making it reusable. However, in this case, the closure is not tamper-evident. Presentation of the invention
[0007] Here, the present invention proposes a solution for closing packaging in a tamper-evident manner, while allowing the packaging to be reused.
[0008] More particularly, the invention proposes a device as defined in the introduction, in which the article receiving and closing parts have at least two slots through which is passed at least one tab which has, on a first side, means for attaching to the article receiving part or to the closing part, and, on a second side, locking means adapted to prevent the withdrawal of said at least one tab from each slot.
[0009] Thus, thanks to the invention, the tabs can be used to seal packages tamper-evidently. When the packages need to be opened, the tabs are designed in such a way that they must be damaged, for example by being torn across their widths.
[0010] By tearing them, it is then possible to open the packages without damaging them.
[0011] Once torn, the tabs can then be extracted from the slots and replaced with new tabs, so that the packages can be reused and resealed in a tamper-evident manner.
[0012] Other advantageous and non-limiting features of the device according to the invention, taken individually or in all technically possible combinations, are as follows: - at least one slot is provided in each of the article receiving and closing parts; - each tab is mounted to slide through at least one slot; - at least two tabs are provided which are respectively threaded through the two slots provided in the article receiving and closing parts, each of the two tabs having hooking means adapted respectively to hook onto the article receiving part and / or the closing part, the locking means being adapted to fix the two tabs together by their second sides; - the two tabs are respectively threaded through the slots provided in the article receiving and closing parts, the hooking means of each of the two tabs being adapted respectively to hook onto the article receiving part and the closing part; - the locking means include an adhesive; - the locking means comprise on said at least one tab a layer of adhesive covered with a peelable lid; - the locking means comprise two layers of adhesive; - the two layers of adhesive are located on the same tab; - the two layers of adhesive are separated from each other on the tab by an area of less resistance and / or a tab cutting accessory; - the item receiving area has a printed area or is covered with a printed label on which an address is written, this area or label being hidden by at least one of the two tabs; - said adhesive layer is suitable for bonding only to an adhesive layer of the same type; - the fastening means include at least one shoulder formed by a widening and / or thickening of the tongue on the first side compared to the second side; - the fastening means include two shoulders formed by a widening of the tongue on the first side compared to the second side; - said at least one tab has, on the second side, an area of less resistance and / or a tab cutting accessory; - said at least one tab is made from at least one cardboard or paper blank; - the two tabs are made from a single piece of cardboard or paper; - the article receiving and closing parts are linked and preferably come from the same cardboard or paper blank; - the item receiving and closing parts are removable from each other; - the article receiving and closing parts each have at least one other slot, said other slots being traversed by at least one other tab which has, on one side, means for hooking to the article receiving part or to the closing part, and, on the other side, locking means adapted to prevent the removal of said at least one other tab from each other slot; - there are provided at least two other tabs which are respectively threaded through the other slots provided in the article receiving and closing parts, the hooking means of which are adapted respectively to hook to the article receiving part and to the closing part and the locking means of which are adapted to fix together.
[0013] Of course, the various features, variants, and embodiments of the invention can be combined in various ways, provided they are not incompatible or mutually exclusive. Detailed description of the invention
[0014] The following description with regard to the attached drawings, given by way of non-limiting examples, will make it clear what the invention consists of and how it can be carried out.
[0015] On the attached drawings:
[0016] [Fig-1] is a schematic plan view of a pre-cut blank which, once placed in volume, will form a device conforming to the invention;
[0017] [Fig.2] is a schematic perspective view of the device according to the invention, before closing;
[0018] [Fig.3] is a detail view of a tab and part of the packaging of the device of the [Fig.2];
[0019] [Fig.4] is a schematic perspective view of the device of [Fig.2], at the time of its closure;
[0020] [Fig.5] is a schematic perspective view of the device of [Fig.2], at the time of its opening;
[0021] [Fig.6] is a schematic plan view of another embodiment of the device in accordance with the invention, before closure;
[0022] [Fig.7] is a schematic perspective view of the device in [Fig.6], after closing.
[0023] In [Fig.1], two pre-cut flanks 100', 200' are shown.
[0024] As a preliminary point, it should be noted that in this figure, solid lines represent cutting lines while dotted lines represent pre-folding lines (hereinafter referred to as "folding lines").
[0025] A cutting line is a line along which the material is cut through.
[0026] A fold line is an area of least resistance that ensures the fold between two panels occurs at the desired position. It can be created in various ways. When the panels are made from a multi-layered cardboard sheet, it can be created by creasing, using a press, or by half-cutting. The creasing operation consists of pressing the multi-layered cardboard sheet along the desired line. The half-cutting operation consists of cutting only a portion of the cardboard sheets along this line.
[0027] Each folding line can alternatively be made in other ways, typically by alternating creasing or half-cut lines with cutting or pre-cut lines.
[0028] A panel will be defined as a portion of blank which is entirely delimited by cutting or folding lines on its edges, and which is internally devoid of such lines.
[0029] Here, each 100', 200' blank is made from a sheet of paper or cardboard. A sheet of paper or cardboard is a thin, opaque, and flexible material made of pressed and dried plant fibers (mainly cellulose). Such a sheet may have one or more superimposed layers. These layers may be flat or corrugated.
[0030] A sheet of paper differs from a sheet of cardboard in its thickness and density (referred to as its basis weight). In practice, a sheet of paper consists of a single, thin layer (generally approximately 0.05 mm to 0.2 mm thick). A sheet of cardboard is thicker than a sheet of paper (over approximately 2 mm thick) and has a higher basis weight (over 224 g / m²). It may be made up of several layers of paper.
[0031] Here, the description relates to a device 1 which includes a package 100 of any shape and at least one tab.
[0032] In the illustrated embodiment, this device 1 comprises a package 100 and two tabs 210, 220.
[0033] In the figures, the packaging 100 is formed by a box, but alternatively, it could have a different shape, typically an envelope shape.
[0034] Here, this packaging 100 is made from a single monobloc piece, by folding a pre-cut cardboard blank 100'.
[0035] The tabs 210, 220 are also derived from a pre-cut cardboard blank 200'.
[0036] On [Fig.1], the packaging 100 and the tabs 210, 220 are shown in the cut but not yet folded state (we will then refer to them in the rest of this presentation as "blanks"), whereas they are shown in the folded state on the following figures.
[0037] The 100', 200' blanks are preferably pre-cut from a multi-layered cardboard sheet (here with three superimposed layers, including a corrugated layer sandwiched between two flat layers): we can then speak of simple or multi-flute corrugated cardboard.
[0038] The 100 box-shaped packaging could come in very diverse forms.
[0039] It could typically be in the form of a single-piece box. Such a box conventionally comprises four panels hinged to one another by parallel fold lines so that these panels, when folded at right angles in pairs, form a band. A lower flap and an upper flap are hinged to each panel. The lower flaps cooperate with each other or are fixed to one another, for example by gluing or using adhesive tapes, so as to form the bottom of the packaging. The upper flaps can be folded in the same way to form the lid of the packaging.
[0040] Alternatively, the packaging could be in the form of a box without a top flap but equipped with a removable cap that can be attached to this box to close it like a lid (this is referred to as a "box with base and lid").
[0041] In the embodiment illustrated in the figures, the packaging 100 is presented in a slightly different form, which can be described in more detail.
[0042] As shown in [Fig.1], it first comprises a rectangular base panel 101.
[0043] It also includes four side panels 102, 103, 104, 105 which are attached respectively to the bottom panel 101 by its four sides, via four main folding lines L102, L103, L104, L105. These four panels, once folded at right angles upwards with respect to the bottom panel 101, together form the side wall of the packaging 100.
[0044] Among these four side panels 102, 103, 104, 105, we distinguish two small side panels 102, 103 articulated with respect to the bottom panel 101 around folding lines L102, L103 parallel to a first axis Al, and two large side panels 104, 105 articulated with respect to the bottom panel 101 around folding lines L104, L105 parallel to a second axis A2.
[0045] Here, the four side panels 102, 103, 104, 105 are connected to each other by bellows 106.
[0046] Each bellows 106 is formed of two panels 106A, 106B articulated to each other by a first fold line inclined at 45° to the first and second axes A1, A2. Each of these two panels 106A, 106B is further articulated on one side of one of the side panels 102, 103, 104, 105 by a second fold line orthogonal to the main fold line connecting this side panel to the bottom panel 101.
[0047] Two of the side panels, here the small side panels 102, 103, each have a flap 107, 108 on the side opposite the bottom panel 101. Each flap 107, 108 is attached to its small side panel 102, 103 by a secondary fold line L107, L108 parallel to the first axis Al. Here, each flap 107, 108 has an isosceles trapezoidal shape. These two flaps are designed to be folded at a right angle to the small side panels 102, 103, parallel to the bottom panel 101, above it.
[0048] One of the large side panels 105 also has a flap 109 on the side opposite the bottom panel 101. This flap 109 is attached to its large side panel 105 by two secondary fold lines L109 parallel to the second axis A2. These two secondary fold lines L109 are placed close together, here at a distance less than or equal to twice the thickness of the cardboard used to make the blank 100'. Thus, this flap 109 is designed to be folded back 180° against the large side panel 105, on the inside of the packaging 100.
[0049] The other of the large side panels 104 has, on the opposite side from the bottom panel 101, a closing wall 140, here of identical shape and size to those of the bottom panel 101. This closing wall 140 is attached to this large side panel 104 by one or two secondary folding lines L140 parallel to the second axis A2. It is thus designed to be folded at a right angle to the large side panel 104, parallel to the bottom panel 101, above it, over the flaps 107, 108.
[0050] For a reason which will become clearer later, this closing wall 140 is formed of two panels 141, 142 connected by a fold line L142 parallel to the second axis A2. These two panels 141, 142 have similar sizes here.
[0051] Finally, this closing wall 140 has a return 143 on the side opposite the side panel 104. This return 143 is attached to the closing wall 140 by a fold line L143 parallel to the second axis A2. Thus, this return 143 is designed to be folded at a right angle to the closing wall 140 to rest against the inner face of the flap 109.
[0052] For the initial shaping of the blank 100', the four side panels 102, 103, 104, 105 are therefore folded at right angles to the bottom panel 101, so that the bellows each fold into the interior volume delimited by these panels.
[0053] These side panels 102, 103, 104, 105, bellows 106, bottom panel 101 and flaps 107, 108, 109, once folded, then form an "item 110 receiving part" in the sense that one or more items of any kind can be housed in this internal volume.
[0054] The closing wall 140 and its return 143 together form a "closing part 150" adapted to close this receiving part of article 110.
[0055] The device 1 comprises, in addition to this packaging 100, two tabs 210, 220 which are threaded through two slots 119, 159 respectively provided in the receiving parts of article 110 and closure 150.
[0056] These slots 119, 159 are preferably located on faces of the packaging 100 (into volume) which are distinct but adjacent.
[0057] In practice, as shown in [Fig.1], a slot 159 is provided here in one of the panels 142 of the closing wall 140, and a slot in the large side panel 105.
[0058] These slots extend lengthwise parallel to the articulation axis of the closing part 150 relative to the receiving part of article 110, that is to say here parallel to the second axis A2.
[0059] These slots are through-slots in the sense that they extend through all the layers of the cardboard used to manufacture the 100' blank. Of course, they could initially be closed by pre-cut flaps.
[0060] They each have a width substantially equal to the thickness of the cardboard blank 200' used to manufacture the tabs 210, 220. Thus the tabs 210, 220 can each be threaded through one of these two slots so as to be able to slide freely in them.
[0061] It should be noted here that the edges of the slots 119, 159 could possibly be reinforced (for example with a thickness of cardboard) or fitted with a film facilitating this sliding.
[0062] Here, as shown in [Fig.1], the two tabs 210, 220 are made from a single blank 200' in cardboard or paper.
[0063] In one embodiment, the two tabs 210, 220 are initially attached to each other by a pre-cut line, which prevents them from being lost. They are therefore designed to be detached from each other just before being inserted through the slots in the packaging.
[0064] Each tab 210, 220 has, on one side, means for attaching it to the packaging 100. At least one of the two tabs also has, on a second on the side, locking means adapted to fix the two tabs 210, 220 to each other by their second sides.
[0065] The fastening means are preferably designed to prevent the sliding of the tabs through the slots in one direction. These are therefore stop means.
[0066] In practice, each tab 210, 220 has, on its second side, a width and thickness less than or equal to the length and width of the slot 119, 159 through which it is engaged. Conversely, each tab 210, 220 has a widening and / or a thickening such that its width and / or thickness on the first side is strictly greater than the length and / or width of the slot 119, 159 through which it is engaged.
[0067] In practice, the tabs 210, 220 have similar shapes.
[0068] Here, each tongue 210, 220 has a T-shape, the crossbar of which forms the first side and the foot of which forms the second side. Each tongue therefore has a widening at the junction between the foot and the crossbar of the T.
[0069] Each tongue 210, 220 thus has two shoulders 211, 221 formed on either side of the foot of the T, by the edge of the crossbar of the T.
[0070] When one of these tabs is threaded into one of the slots 119, 159 by its second side (the foot of the T), the two shoulders 211, 221 are designed to block the sliding of this tab by coming to rest against the panel (105, 142) in which the slot is cut.
[0071] Here, the tabs are designed to be inserted into the slots from the inside of the packaging, so that their first sides (the crossbar of the T) remain housed in the packaging 100 and their second sides (the foot of the T) protrude out of the packaging 100.
[0072] The locking means, which, it should be recalled, allow the two tabs 210, 220 to be connected together from the outside of the packaging, could be in various forms.
[0073] They could, for example, be in the form of staples adapted to connect the feet of the two tabs 210, 220.
[0074] But, preferably, it is rather a question of means of gluing.
[0075] It could therefore be provided for to bring one or more drops of glue between the two tabs to fix them together by their second sides (the foot of the T).
[0076] But, preferably, these means comprise, on at least one of the two tabs 210, a layer of adhesive 212 covered with a peelable cover 213. Here, the layer of adhesive 212 forms a band which extends over the entire width of the foot of the T, on the side opposite the crossbar of the T.
[0077] Thus, it will be sufficient to remove this peelable lid 213 to fix the two tabs 210, 220 together, by pressing them against each other.
[0078] Alternatively, it could be provided that the two tabs each have a layer of adhesive.
[0079] In this embodiment, the adhesive could be of the type that only adheres to another layer of adhesive of the same type. This is referred to as a "self-adhesive layer." The use of such self-adhesive layers would prevent one of the tabs from being accidentally stuck to the packaging, which could otherwise damage it and prevent its reuse. Such an adhesive is known and comprises, for example, a latex-based coating that sticks to itself and can only be removed by peeling off the substrate to which it is attached.
[0080] As shown in [Fig.1], one of the tabs 210 preferably has a folding line L1 at its foot.
[0081] Thus, with the two tabs 210, 220 coming out of the packaging 100 from two distinct sides thereof, it is possible to fold one of these tabs 210 at the level of the corresponding edge of the packaging 100.
[0082] Preferably, one of the two tabs 220 has, at its base, a zone of lesser resistance and / or a cutting accessory. This zone or accessory is designed to allow, when the two tabs are glued together, for one of them to be torn in order to allow the packaging 100 to be reopened without damaging it.
[0083] In the embodiment shown here, one of the tabs 220 has two pre-cut lines parallel to the second axis A2, which delimit between them a strip 223 extending over the entire width of the foot. Preferably, this strip 223 extends beyond one side of the foot by means of an appendage 224 facilitating its gripping.
[0084] Thus, a user can tear this tab across its entire width by grasping the appendage 224 to force the section to tear and separate the tab into two parts.
[0085] At this stage, we can describe how device 1 can be used and reused.
[0086] Once the packaging 100 has been folded into volume in the aforementioned manner (by folding the side panels forward), it is possible to install the tabs 210, 220.
[0087] These two tabs 210, 220 are therefore separated from each other if they are delivered in one piece, by cutting them along a pre-cut line provided for this purpose.
[0088] As shown in Figures 2 and 3, they are then threaded through the two slots 119, 159, sliding them into the slots until they reach a position where their shoulders 211, 221 come to rest against the inner faces of the panels in which the slots are cut.
[0089] During this operation, the folding line L142 provided between the panels 141, 142 of the closing wall 140 facilitates the placement of the tabs through the slots.
[0090] The operator can then fold the flap 109 inwards against the side panel 105. Then he can place any articles in the interior volume delimited by the bottom panel 101 and the side panels 102, 103, 104, 105.
[0091] So, before closing the package 100, he folds the flaps 107, 108 over these items. Then he folds the closing panel 140 over these flaps 107, 108, taking care to engage the return 143 in the package 100, against the inner face of the flap 109.
[0092] Therefore, to close this packaging 100 in a tamper-evident manner, it uses the pair of tabs 210, 220.
[0093] The peelable cover 213 of the adhesive layer 212 is for this purpose removed ([Fig.4]), then the two tabs 210, 220 are applied against each other by their second sides, so that this adhesive layer assembles them but does not adhere to the packaging 100.
[0094] Thus, the packaging 100 is closed in a tamper-evident manner since it is no longer possible to access its internal volume without tearing it or without tearing the tabs 210, 220.
[0095] To open it, a user can then tear one of the tabs across its entire width, here by grasping the appendage 224 provided for this purpose at the end of the strip 223 ([Fig.5]).
[0096] It is then understood that the user can then remove the tabs 210, 220 from the slots 119, 159, and reuse the packaging 100, possibly using a new pair of new tabs for this purpose.
[0097] It may be noted here that, when the tabs 210, 220 are fixed to each other, they together conceal a part of the packaging 100 on which a return address is written.
[0098] Thus, after receiving a package, if the item contained in this package 100 is not suitable for the buyer, he can return it using the same package 100. In this case, he can close the package 100 in a way other than with tabs, for example by means of adhesive tape, so as not to hide the return address.
[0099] Alternatively, package 100 could be sent with a pair of new tabs usable in case of return of item, this pair of tabs being pre-printed with the return address.
[0100] The present invention is in no way limited to the embodiment described and represented, but a person skilled in the art will be able to make any variation in accordance with the invention.
[0101] Typically, in the case of a box with a base and lid, two pairs of tabs can be used to attach the lid to the base. Two slots can thus be made in two opposite side panels of the box, and two slots in the lid.
[0102] According to another embodiment, in the case of a box with a base and lid, a single pair of tabs can be used to attach the lid to the base. Two slots can be made in two opposite side panels of the box, the two tabs inserted through these slots, folded over the lid, and then glued together.
[0103] According to another embodiment of the invention, packaging as illustrated in the figures could be used, and a single long, constant-width tab. This tab would then be threaded through the two slots so that its two ends protrude outside the packaging and can be glued together.
[0104] According to another embodiment of the invention, a one-piece box could be used, in which at least two of the upper flaps have overlapping slots, and a single T-shaped tab. This tab could be inserted through these overlapping slots so that its shoulders rest against the inner face of one of the upper flaps. The foot of the T, then located outside the packaging, could be folded or rolled back on itself and then glued to itself to hold it in this configuration, which would prevent the tab from sliding through the slots and would thus lock the one-piece box.
[0105] As a further alternative, the article receiving part could be in the form of a simple flat panel, and the closing part could be a bell-shaped cap that fits onto the flat panel.
[0106] More generally, the article receiving part and the closing part could have very varied shapes.
[0107] For example, as shown in Figures 6 and 7, in a second embodiment of the invention, the article receiving part may form the body 180 of an envelope while the closing part 150 will form a flap 190 hinged on the body 180.
[0108] We can briefly describe this second embodiment of the invention.
[0109] The body 180 of the envelope classically has two parallel walls 181, 182, rectangular and overlapping. One is usually made from a single piece of cardboard or paper, while the other is made from several pieces of cardboard glued together.
[0110] These two walls 181, 182 are connected by their edges, here on three of their four sides, directly or by bellows.
[0111] The flap 190 is attached to the fourth side of one of these two walls 182, here by a fold line L182, so that it can be folded against the outer face of the other of these two walls 181.
[0112] As illustrated in figures 6 and 7, it is then preferably provided two slots 185, 195, one in this other wall 181 and the other in the flap 190.
[0113] Two tabs 280, 290 similar to those described with reference to Figures 1 to 5 are then inserted through these two slots 185, 195, so that their shoulders abut against the inner faces of these walls 181 and flaps 190, and so that they can be glued one over the other on the outer side of the envelope. One of these tabs 290 has at least one strip of adhesive 291 for this purpose.
[0114] It could consist of only one strip of adhesive.
[0115] However, as clearly shown in [Fig. 6], it comprises two separate adhesive strips 291, 292. Here, these two strips are parallel. They are separated by an area in which there is a detachable strip 293 (defined between two pre-cut lines).
[0116] The other tab 280 has only a detachable strip 283 (defined between two pre-cut lines).
[0117] In addition, a printed area or label 189 is provided on the wall 181 indicating a return address (in anticipation of a possible return of the item).
[0118] As shown in [Fig.7], when the tabs 280, 290 are fixed to each other by the adhesive strip 292 (the one located closest to the end of the second side of the tab 290), they together hide this printed area or label 189.
[0119] To open the envelope, it is planned to tear at least one of the two detachable strips 283, 293.
[0120] If the recipient ever wishes to return the envelope, he will have to tear these two detachable strips 283, 293, remove the tab 280 from the envelope and stick the other tab directly onto the envelope using the second adhesive strip 291. Thus closed, the envelope could be returned directly by post since the return address written on the printed area or on the label 189 would then be visible.
