Description

Packaging comprising a tray, a sheath and a tamper evidence of the packaging

The present invention relates to a package, of the type comprising a tray and a sheath inside which the tray is slidably mounted in a longitudinal direction, the package further comprising at least one inviolability indicator of the package, said witness tamper evidence comprising:

a first integral section of the tray, and

a second section linked by at least one line of weakness to the sheath. The invention also relates to a blank for forming such a package.

The invention applies more particularly to the packaging of individual portions of packaged food products, for example and without limitation:

portions of dairy products such as, but not limited to, cheese, products comprising a cheese base and / or a dairy base,

- portions of dairy substitute products,

portions of composite products comprising at least one dairy base and at least one other non-dairy base, for example a cereal base,

- portions of food products based on vegetable matter,

- portions of confectionery or chocolate products,

portions of culinary aid products of the cube broth type or derivatives. The products contained in packs formed of a tray slidably mounted in a sheath are commonly theft, especially in supermarket shelves, since these packages can be opened and closed simply by sliding the tray out of the sheath then again towards the inside of the scabbard.

To remedy this, packages with a tamper evidence are known.

Thus, for example, there is known from EP 1 652 781 a package comprising a tray and a tubular sheath provided with a tamper evidence. The tray is provided with an end closure structure. A detachable portion of the sleeve cooperates with the end closure structure to prevent access to the tray when the package is intact.

Such packaging, however, requires the design of a complex and expensive tray, as well as the use of a large amount of raw materials. The packaging obtained is also more bulky than a packaging without tamper evidence. EP 1 637 460 and US 2009/0261 155 also disclose packagings comprising a tray and a tubular sheath inside which the tray is slidably mounted, each package comprising a tamper evidence.

In EP 1 637 460, the tamper evidence is constituted by a tear strip formed of a portion with the tray and folded on the sleeve. To open the package, a user must tear off the tape, then grab the tray and remove it from the sheath.

In US 2009/0261 155, the inviolability indicator is formed of two tabs each formed of a portion with the tray and the sheath, folded and glued on the sheath. To open the package, the user must take off the tabs of the sheath, tear them off the package, then grab the tray and remove it from the sheath.

An object of the invention is to facilitate the opening of the package and the withdrawal of the tray out of the sheath. Another goal is to limit the amount of raw materials used, as well as the cost of packaging.

For this purpose, the invention relates to a package of the aforementioned type, wherein the or each line of weakness opens into a longitudinal end edge of the sheath.

According to particular embodiments of the invention, the packaging also has one or more of the following characteristics, taken in isolation or according to any combination (s) technically possible (s):

- The sheath comprises a bottom, a roof, and two side walls connecting the bottom to the roof, the sheath having at least one notch formed in one of the roof, the bottom and at least one of the two side walls of the sheath ;

the second section of the inviolability witness is housed in the notch or one of the notches;

the notch comprises a first region occupied by the inviolability witness and a second region left free;

the tray comprises a front end panel in the longitudinal direction, the first section of the tamper evident being secured to said front end panel;

the first section of the inviolability witness is connected to the second section of the inviolability witness by a line of weakness;

the first section of the inviolability indicator has a T-shape, a semi-discoidal shape, a quadrangular shape, a rounded shape, or an oval shape;

- The inviolability indicator is formed of a part with the sleeve and is folded on the tray; - The tamper evidence is formed of a portion with the tray and is folded over the sheath.

The invention also relates to a blank for forming such a package.

Other features and advantages of the invention will appear on reading the description which follows, given solely by way of example and with reference to the appended drawings, in which:

Figures 1 and 2 are top views respectively of a first portion and a second portion of a blank, presented flat, to form a package according to a first preferred embodiment of the invention, Figure 3 is a perspective view, front and bottom, of a package formed with the blank of Figures 1 and 2, the package being closed,

Figure 8 is a view similar to that of Figure 7, the package being partially open,

Figures 9 and 10 are top views respectively of a first portion and a second portion of a blank, presented flat, to form a package according to a third embodiment of the invention,

Figure 11 is a perspective view, front and top, of a package formed with the blank of Figures 9 and 10, the package being closed, and Figure 12 is a view similar to that of Figure 1. 1, the package being partially open.

The blank 10 of Figures 1 and 2 is intended for the constitution of the package 200 of Figures 3 and 4. For this purpose, the blank 10 comprises a first portion 12, shown in Figure 1, especially for the constitution of a tray 14 (Figure 3) of the package 200, and a second portion 16 shown in Figure 2 specially intended for the constitution of a tubular sheath 18 (Figure 3) of the package 200.

Here and in the following, the terms "tube" and "tubular" are to be understood according to all their possible meanings and are not limited to the cylindrical form of revolution. Thus, once formed, the sheath 18 has a cross section of any technically feasible form. Preferably, the sheath 18 has a cross section of rectangular shape.

The blank 10 'of Figures 5 and 6 is intended for the constitution of the package 200' of Figures 7 and 8. For this purpose, the blank 10 'comprises a first portion 12', shown in Figure 5, especially for the constitution of a tray 14 '(Figure 7) of the package 200', and a second portion 16 'shown in Figure 6 specially intended for the constitution of a tubular sheath 18' (Figure 7) of the package 200.

The first portions 12, 12 'of the blanks 10 and 10' are identical. Thus, the description of the first portion 12 of the blank 10, given here with reference to Figure 1, is also applicable to the first portion 12 'of the blank 10'.

The first portion 12 is elongate in a first longitudinal direction.

Preferably, the first portion 12 is composed mainly of cardboard. According to another embodiment, the first part is composed mainly of rigid plastic.

The first portion 12 advantageously has a total thickness of between 100 and 2500 microns when unfolded, preferably between 200 and 800 microns.

The first portion 12 comprises a main region 20 and two end regions 22 disposed on either side of the main region 20 in the longitudinal direction.

The main region 20 typically has a generally rectangular shape.

The main region 20 comprises three panels 24, 26, 28 side by side, a central panel 24 and two side panels 26, 28 disposed on either side of the central panel 24 in a first transverse direction ΤΊ substantially perpendicular to the longitudinal direction .

The three panels 24, 26, 28 are interconnected by longitudinal fold lines 30, 32 extending substantially parallel to the longitudinal direction.

The central panel 24 is intended to form a base 34 (FIG. 4) of the tray 14, and the two side panels 26, 28 are intended to form two opposite side walls 56, 58 (FIG. 4) of the tray 14.

Preferably, the two side panels 26, 28 are substantially identical in shape and size.

The end regions 22 are connected to the main region 20 by transverse fold lines 40, 41 extending in the transverse direction TV

Preferably, the end regions 22 are, as shown, symmetrical relative to one another relative to a median transverse plane (not shown) of the first portion 12. Typically, each end region 22 comprises an end closure flap 42 and two longitudinal flaps 44 placed on either side of the end closure flap 42 in the transverse direction T The end closure flap 22 is connected to the main region 20 by a first transverse fold line 40, and each of the longitudinal flaps 44 is connected by a second transverse fold line 41 to a respective side panel 26, 28.

The end closure flap 42 comprises two panels 46, 48 side by side in the longitudinal direction. Subsequently, the panel 46 connected to the main region 20 is called the proximal panel 46, the other panel 48 being called the distal panel 48.

The distal panel 48 and the proximal panel 46 are connected by a fold line

50 extending substantially parallel to the transverse direction T

The distal panel 48 and the proximal panel 46 are substantially identical in size so that they can be folded over each other.

Preferably, the distal panel 48 comprises two locking teeth 52 intended to engage in slots 54 formed in the fold line 40 between the end closure flap 42 and the central panel 24 of the main region 20.

To assemble the tray 14 of Figures 3 and 4 or the tray 14 'of Figures 7 and 8, the flaps 44 are first raised in a direction of elevation (not shown), perpendicular to the longitudinal and transverse directions T _1; following the fold lines 41.

The side panels 26, 28 of the main region 20 are then raised in the direction of elevation and along the fold lines 30, 32 to form the side walls 56, 58 of the tray 14. In doing so, the flaps 44 switch into a position where they are oriented transversely.

The end closure flaps 42 are then raised in the elevation direction along the fold lines 40, so that the proximal panel 46 of each flap 42 comes into contact with the flaps 44.

Finally, the distal panel 48 of each end closure flap 42 is folded over the associated proximal panel 46 at the fold line 50, the locking teeth 52 being engaged in the corresponding slots 54. In doing so, the flaps 44 are trapped between the distal panel 48 and the side panel 46 of each end closure flap 42, which locks the side walls 56, 58 in the upright position.

The trays 14, 14 'are therefore simple to assemble.

Referring to Figures 2 and 6, the second portions 16, 16 'of the blanks 10 and 10' are each elongate in a second longitudinal direction L ₂ . Preferably, said second portions 16, 16 'are composed mainly of cardboard. According to another embodiment, the second part 16, 16 'is composed mainly of rigid plastic.

Each second portion 16, 16 'advantageously has a total thickness of between 100 and 2500 microns when unfolded, preferably between 200 and 800 microns.

Each second portion 16, 16 'comprises a main region 80 and a tongue 82 forming a tamper evidence connected to the main region 80.

The main region 80 comprises four panels 84, 86, 88, 90 and a connecting end strip 92 arranged side by side. The four panels 84, 86, 88, 90 and the terminal connecting strip 92 are interconnected by fold lines 94, 96, 98, 100 extending substantially parallel to the longitudinal direction L ₂ .

The four panels 90, 86, 84, 88 are intended to form respectively a bottom 102 (Figures 3 and 8), a roof 104 (Figures 3 and 8) opposite the bottom 102 and two side walls 106, 108 (Figures 3 and 8 ) connecting the bottom 102 to the roof 104 of the sleeve 18, 18 '. Alternatively, the panel 86 is intended to form the bottom 102 of the sleeve 18, 18 ', and the panel 90 is intended to form the roof 104.

In the example shown, the panels 86, 90 for forming the roof 104 and the bottom 102 of the sleeve 18 have substantially identical dimensions.

According to the example shown, the panels 84, 88 intended to form the two side walls 106, 108 have substantially identical dimensions.

In the present description, the bottom 102 and the roof 104 of the sheath 18 are defined relative to the tray 14 when it is inserted into the sheath 18, the base 34 of the tray 14 facing the bottom 102 of the sheath 18, and the open portion of the tray 14 facing the roof 104 of the sleeve 18.

The panels 84, 86, 88, 90 are dimensioned so that, once assembled, the tray 14 can be slidably mounted in the sleeve 18.

The main region 80 has a first longitudinal end edge 109a, said front longitudinal end edge 109a, and a second longitudinal end edge, said rear longitudinal end edge 109b opposite the longitudinal leading end edge 109a.

The tongue 82 is attached to the main region 80. Preferably, the tongue 82 is integrally formed with said main region 80.

The tongue 82 comprises a first free portion 10 and a second portion 1 12 bonded to the main region 80. In particular, the first portion 1 10 and the second portion 1 12 are juxtaposed to each other in a first direction of the tongue 82 and each extend over the entire width of the tongue 82 in a second direction orthogonal to the first direction.

In the particular case of the first embodiment, shown in FIG. 2, the first section 1 has a T-shape. In the particular case of the second embodiment, shown in FIG. rectangular shape. Alternatively, the first section 1 10 has another shape, for example a semi-discoidal shape, a quadrangular shape, a rounded shape, or an oval shape.

The second section 1 12 has a first end 1 14 connected to the first section 1 10 and a second free end 1 16 said gripping end 1 16 opposite the first end 1 14.

In the particular case of the first embodiment, shown in Figure 2, the second section 1 12 of the tongue 82 is connected to the first section 1 10 by a fold line 1 18 extending substantially parallel to the transverse direction T ₂ along the first end 14.

In the particular case of the second embodiment, shown in Figure 6, the first section 1 10 is connected to the second section 1 12 of the tongue 82 by a line of weakness 1 18 'extending substantially parallel to the transverse direction T ₂ along the first end 1 14. Said line of weakness 1 18 'is typically formed by a precut in the carton forming the second portion 16'.

The second section 1 12 is connected to the main region by at least one line of weakness 120. These lines of weakness 120 are typically formed by pre-cuts in the cardboard forming the second part 16, 16 '.

According to the invention, the or each line of weakness 120 opens into one of the longitudinal end edges 109a, 109b of the main region 80, typically in the longitudinal end edge before 109a. In particular, the or each line of weakness 120 extends longitudinally from the gripping end 1 16 of the second section 1 12 to said longitudinal end edge 109a, 109b in which it opens.

Thus, the exercise of a force on the gripping end 1 16 of the second section 1 12 of the tongue 82 whose intensity is large enough to break the or each line of weakness 120 and whose direction comprises a longitudinal component causes the rupture of the or each line of weakness 120.

In the particular case of the first embodiment, shown in FIG. 2, the lines of weakness 120 are two in number, each opening into the longitudinal end edge before 109a and substantially forming the two branches of a V whose tip is formed by the grip end 1 16. In the particular case of the second embodiment, shown in Figure 6, the lines of weakness 120 are two in number, each opening into the longitudinal end edge before 109a and are substantially parallel to the longitudinal direction L ₂ . The second section 1 12 of the tongue 82 then has a substantially rectangular shape.

Preferably, the second portions 16, 16 'of the blanks 10 and 10' have at least one notch 122 formed in one of the panels 84, 86, 88, 90 of the main region 80, said notch 122 opening into one longitudinal end edges 109a, 109b of the main region 80, typically in the front longitudinal end edge 109a. In the present description, the term "notch" denotes a small notch or cut.

The second section 1 12 of the tongue 82, more particularly the gripping end 1 16 of this second section January 12, is housed in said notch 122 or in one of said notches 122.

Preferably, the notch 122 comprises a first region 124 occupied by the tongue and a second region 126 left free.

The second region 126 left free thus leaves a nail passage allowing a user to easily grasp the grip end 1 16 of the tongue.

In the particular case of the first embodiment shown in Figure 2, the notch 122 is formed in the panel 90 for forming the bottom of the sleeve 18, the second section 1 12 of the tongue being housed in said notch 122.

In the particular case of the second embodiment shown in FIG. 6, the notch 122 is formed in one of the panels 84, 88 intended to form one of the side walls 106, 108 of the sleeve 18, the second section 1 12 of the tongue 82 being housed in said notch 122.

To assemble the sleeve 18 of Figures 3 and 4, the four panels 84, 86, 88, 90 of the second portion 16 of the blank 10 are folded along the fold lines 94, 96, 98 to form a tube.

The terminal connecting strip 92 is folded along the fold line 100 which connects it to the main region 80. It is fixed, for example glued, to the adjacent side wall 106 of the sleeve 18 so as to laterally close the sleeve 18.

Thus, once the sleeve 18 assembled, the panel 90 of the second portion 16 of the blank 10 constitutes the bottom 102 of the sleeve 18, the panel 86 constitutes the roof 104, and the panels 84 and 88 constitute the side walls 106 and 108. In addition, the front longitudinal end edge 109a of the second portion 16 of the blank 10 constitutes an edge longitudinal end end of the sleeve 18, and the rear longitudinal end edge 109b constitutes a rear longitudinal end edge of the sleeve 18.

Alternatively (not shown), the panel 86 constitutes the bottom 102 of the sleeve 18, and the panel 90 constitutes the roof 104.

The sheath 18 'of Figures 7 and 8 is assembled in the same manner as previously described for the blank 18, the second portion 16' of the blank 10 'being simply substituted for the second portion 16 of the blank 10.

Thus, the assembly of the sleeves 18, 18 'is very easy and easily mechanizable.

To form each of the packages 200, 200 'of FIGS. 3, 4 and 7, 8, the tray, respectively 14, 14', is first filled with a plurality of articles A (FIG. 8), then inserted into the corresponding sheath, respectively 18, 18 ', so as to place the base 34 of the tray 14, 14' against the bottom 102 of the sheath 18, 18 'and coincide the longitudinal directions and L ₂ , said longitudinal directions and L ₂ forming a longitudinal direction L of the package 200, 200 '.

Articles A are, for example, food products, in particular individual portions of packaged food products, for example and without limitation:

- portions of dairy substitute products,

- portions of food products based on vegetable matter,

- portions of confectionery or chocolate products,

portions of culinary aid products of the cube broth type or derivatives. The first section 1 10 of the tongue 82 is then secured to the tray 14, 14 ', in particular at one of the two end panels 60 of said tray 14, 14', to seal the package 200 and to form a witness of inviolability. Typically, the first section 1 10 of the tongue 82 is folded and then glued to said end panel 60.

This panel 60 is said front end panel 60 of the tray 14, 14 '. It has a central zone 202 and two end zones 204, 206 arranged transversely on either side of the central zone 202.

Thus, in the example shown, when the package 200, 200 'is sealed, there is a non-zero angle and different from 180 ° between the first section 1 10 and the second section 1 12 of the tongue 82. Moreover, the first stretch 1 10 belongs to a face of the package 200, 200 'different from the face of the package 200, 200' to which belongs the second section 1 12.

In the first embodiment, the first section 1 10 of the tongue 82 is secured to the central zone 202 of the front end panel 60. In the second embodiment, the first section 1 10 of the tongue 82 is rendered secured to one of the end zones 204, 206 of the front end panel 60.

The packages 200, 200 'thus formed have a substantially parallelepiped shape.

To unseal these packages 200, 200 ', simply grasp the second section 1 12 of the tongue 82 by the gripping end 1 16 and detach it from the sleeve 18, 18' by breaking the or each line of weakness 120 into exerting a force on the gripping end 1 16 of the second section 1 12 of the tongue 82 whose intensity is large enough to break the or each line of weakness 120 and whose direction comprises a longitudinal component causing the breaking of the or each line of weakness 120, the second section 1 12 remaining connected to the first section 1 10 itself remaining glued to the tray 14, 14 '.

The user can then slide the tray 14, 14 'in a single longitudinal movement by pulling on the second section 1 12 of the tongue 82 while continuing to exert the force on the gripping end 1 16.

It will be noted on this occasion that the particular T shape of the first section 1 10 in the particular case of the first embodiment allows in particular a better holding of the tongue 82 on the tray 14 at the time of withdrawal of the tray 14 by pulling on the tongue 82. As for the line of weakness 1 18 'specific to the second embodiment, it allows to easily detach the second section 1 12 of the package 200 once the latter open.

The package 200, 200 'once opened can be closed by sliding the tray, respectively 14, 14', inside the sheath, respectively 18, 18 '.

For example, the package 200, 200 'is closed by exerting a force on the gripping end 1 16 of the second section 1 12 of the tongue 82 in the same direction and in a direction opposite to the force exerted during the opening of the package 200, 200 '.

Each distal side panel 218, 224 is folded over the proximal side panel 220, 222 associated with the fold line 226, 230. In doing so, the transverse flaps 262 are trapped between the distal side panel 218, 224 and the panel proximal lateral 220, 222, which allows to lock the side walls 56, 58 in the rectified position.

The tray 14 "is then completed, each tab 215 extending out of the tray 14" transversely to the front end panel 261 (Figure 1 1).

Referring to Figure 10, the second portion 16 "of the blank 10" is elongated in a second longitudinal direction L " ₂ .

Preferably, said second portion 16 "is composed mainly of cardboard In another embodiment, the second portion 16" is composed mainly of rigid plastic.

The second portion 16 "advantageously has a total thickness of between 100 and 2500 microns when unfolded, preferably between 200 and 800 microns.

The second part 16 "comprises a main region 380.

The main region 380 comprises four panels 384, 386, 388, 390 and a connecting terminal strip 392 arranged side by side. The four panels 384, 386, 388, 390 and the terminal connecting strip 392 are interconnected by fold lines 394, 396, 398, 400 extending substantially parallel to the longitudinal direction L " ₂ .

The four panels 390, 386, 384, 388 are intended to form respectively a bottom 402 (Figure 1 1), a roof 404 (Figure 12) opposite the bottom 402 and two side walls 406, 408 (Figures 1 1 and 12) connecting the bottom 402 on the roof 404 of the sleeve 18 "In a variant, the panel 386 is intended to form the bottom 402 of the sleeve 18" and the panel 390 is intended to form the roof 404.

According to the example shown, the panels 386, 390 for forming the roof 404 and the bottom 402 of the sleeve 18 "have substantially identical dimensions. According to the example shown, the panels 384, 388 intended to form the two side walls 406, 408 have substantially identical dimensions.

In the present description, the bottom 402 and the roof 404 of the sheath 18 "are defined relative to the tray 14" when it is inserted into the sheath 18 ", the base 234 of the tray 14" facing the bottom 402 of the 18 "sheath, and the open portion of the tray 14" facing the roof 404 of the sheath 18 ".

The panels 384, 386, 388, 390 are sized so that, once assembled, the tray 14 "can be slidably mounted in the sleeve 18".

The main region 380 has a first longitudinal end edge 409a, said front longitudinal end edge 409a, and a second longitudinal end edge, said rear longitudinal end edge 409b opposite the front longitudinal end edge 409a.

To assemble the sheath 18 "of Figures 1 1 and 12, the four panels 384, 386, 388, 390 of the second portion 16" of the blank 10 "are folded along the fold lines 394, 396, 398 to form a tube.

The terminal connecting strip 392 is folded along the fold line 400 which connects it to the main region 380. It is fixed, for example glued, to the adjacent side wall 406 of the sleeve 18 "so as to laterally close the sleeve 18" .

Thus, once the sleeve 18 "assembled, the panel 390 of the second portion 16 of the blank 10" constitutes the bottom 402 of the sleeve 18 ", the panel 386 constitutes the roof 404", and the panels 384 and 388 constitute the side walls 406 and 408. In addition, the front longitudinal end edge 409a of the second portion 16 "of the blank 10" constitutes a front longitudinal end edge of the sleeve 18 ", and the rear longitudinal end edge 409b constitutes an edge rear longitudinal end of the sheath 18 ".

Alternatively (not shown), the panel 386 constitutes the bottom 402 of the sheath

18 ", and the panel 390 constitutes the roof 404.

Thus, the assembly of the sheath 18 "is very easy and easily mechanizable.

To form the package 200 "of Figures 1 1 and 12, the tray 14" is first filled with a plurality of items A (Figure 12), then inserted into the sleeve 18 ", so as to place the base 234 of the tray 14 "against the bottom 402 of the sleeve 18" and coincide the longitudinal directions L "-, and L" ₂ , said longitudinal directions L "- and L" ₂ forming a longitudinal direction L "of the package 200 ".

portions of dairy products such as, but not limited to, cheese, products comprising a cheese base and / or a dairy base, - portions of dairy substitute products,

- portions of food products based on vegetable matter,

- portions of confectionery or chocolate products,

portions of culinary aid products of the cube broth type or derivatives. Each tongue 215 is then secured to the sheath 18 ", particularly at the side walls 406, 408 of said sheath 18", to seal the package 200. Typically, each tongue 215 is folded and then its first portion 286 is glued to said respective end panel 406, 408, the second portion 288 remaining preferably free of glue.

Thus, once the tongue 215 has been glued, a tamper proof indicator 500 of the package 200 "is obtained, comprising a first section 502 constituted by the proximal panel 266, integral with the container 14", and a second section 504 constituted by the second portion 288 of the tongue 215 bounded by the lines of weakness 294 to the sheath 18 ", each line of weakness 294 opening into one of the longitudinal end edges of the sheath 18", in particular in the front longitudinal end edge . In addition, each line of weakness 294 extends longitudinally from the gripping end 292 of the second portion 288 to said longitudinal end edge into which it opens.

In particular, the first section 502 and the second section 504 are then juxtaposed with each other in a first direction of the inviolability indicator 500 and each extend over the entire width of the inviolability indicator 500 according to a second orthogonal direction to the first direction.

Furthermore, when the package 200 "is sealed, there is then a non-zero angle and different from 180 ° between the first section 502 and the second section 504 of the tongue 215.

In addition, the first section 502 then belongs to a face of the package 200 "different from the face of the package 200" to which the second section 504 belongs.

Thus, the exercise of a force on the gripping end 292 of the second portion 288 of the tongue 215 whose intensity is large enough to break each line of weakness 294 and whose direction comprises a longitudinal component causes the rupture each line of weakness 294.

The package 200 "thus formed has a substantially parallelepiped shape. To unseal this package 200 ", simply grasp the second portion 288 of each tab 215 by the gripping end 292 and detach the sheath 18" by breaking each line of weakness 294 by exerting a force on the end of gripping 292 of the second section 504 of the tongue 215 whose intensity is large enough to break the or each line of weakness 294 and whose direction comprises a longitudinal component causing the breaking of the or each line of weakness 294. The second part 288 remains nevertheless integral with the tray 14 ".

The user can then slide the tray 14 "in a single longitudinal movement by pulling on the second portion 288 of one or each tongue 215 by continuing to exert the force on the gripping end 292..

The package 200 "once opened can be closed by sliding the tray 14" inside the sleeve 18 ".

For example, the package 200 "is closed by exerting a force on the gripping end 292 of the second section 504 of the tongue 215 in the same direction and in a direction opposite to the force exerted during the opening of the 200 "packaging.

According to the embodiments described, the tray 14, 14 ', 14 "and the sheath 18, 18', 18" each have a substantially parallelepiped shape.

However, other forms are conceivable. For example, according to undescribed variants of the invention, the tray 14, 14 ', 14 "and the sheath 18, 18', 18" have a trapezoidal shape, cylindrical or partially cylindrical, or any other form technically feasible in the scope of the invention.

Thanks to the invention, the user thus manages to unseal the package 200, 200 ', 20 "and remove the tray 14, 14', 14" of the sleeve 18, 18 ', 18 "in one and the same movement In addition, the quantity of raw materials remains limited, as well as the cost of packaging 200, 200 ', 200 ". The sleeve 18, 18 ', 18 "is also easily achieved by machines.

Furthermore, it is not necessary to adapt the tray 14, 14 'to the inviolability system of the package 200, 200', which allows the use of standard trays for these. Similarly, it is not necessary to adapt the sheath 14 "to the tamper-proof system of the package 200", which allows to use a standard sheath for the latter.
