Abstract

Tamperproof closures for securing a lid to a plastic box with a rolled lip take the form of a curved eye shade located on each of four rounded corners on the lid. These caps on each corner of the lid have an internal lip to engage the edge of the rim of the box, and are slotted on a level intermediate between that of the internal lip and the top of the box, pref. level with half the depth of the box rim. The caps remain intact when the lid is first pushed on to the box, but break when the tips of the caps have to be pulled outwards to release the lid. Simpler to make and use than designs involving peripheral pull tapes to release the lid. Pref. the lids have an internal lug near each corner for supporting the lids when stacked for storage, to avoid strain on the caps. In an alternative design, the cap incorporates a slot deep enough to accommodate part of the lip of the rim of the lid which is inclined outwards.

Description

L'invention a pour objet un couvercle inviolable pour notamment un emballage en matière plastique formant boite. The subject of the invention is a tamper-evident cover, in particular for a plastic packaging forming a box.

L'objet de l'invention se rattache aux secteurs techniques de l'emballage et du conditionnement. The object of the invention relates to the technical sectors of packaging and packaging.

I1 est connu de réaliser des couvercles, bouchons et similaires, avec des prolongements formant dans leur plan des ban- zes detachables par rapport à leur support, et s'ajustant sr des boitiers de façon qu'il soit nécessaire d'enlever les bandes détachables pour avoir accès au contenu du boîtier. It is known practice to produce covers, plugs and the like, with extensions forming detachable strips in their plane relative to their support, and adjusting to housings so that it is necessary to remove the detachable strips. to access the contents of the box.

On a constaté à l'expérience que ce type de moyens assurant l'inviolabilité des emballages en position fermée présentait certains inconvénients pour des emballages notamment quadrangulaires et lorsque ceux-ci étaient utilisés et stockés dans des endroits à très basse température (de l'ordre de - 20 degrés cen tirades) tels que congélateurs, chambres froides et autres. On a constaté notamment la fragilité des bandes détachables qui sont cassantes très facilement, aussi il est nécessaire pour enlever complètement une bande de procéder à plusieurs opérations successives de préhension et d'arrachage, cet arrachage se faisant dans une direction parallèle au bord du couvercle. Experience has shown that this type of means ensuring the inviolability of packaging in the closed position has certain disadvantages for packaging, in particular quadrangular, and when these are used and stored in places at very low temperatures (of the order de - 20 degrees cen tirades) such as freezers, cold rooms and others. It has been noted in particular the fragility of the detachable strips which are very easily brittle, so it is necessary to completely remove a strip to carry out several successive gripping and tearing operations, this tearing taking place in a direction parallel to the edge of the cover.

En outre, la préhension de ces bandes détachables s'avère difficile et mal aisée et à forciori lorsque celles-ci sont partiellement cassées. In addition, the gripping of these detachable tapes proves difficult and uneasy and a fortiori when they are partially broken.

Le but recherché selon l'invention est donc de concevoir un couvercle inviolable qui supprime les inconvénients précités. Pour cela et après de nombreux essais reproduisant les données d'utilisation de tels emballages, on a mis au point un couvercle inviolable d'une conception nouvelle, s'adaptant facilement sur le corps du boîtier. The aim sought after according to the invention is therefore to design a tamper-evident cover which eliminates the aforementioned drawbacks. For this and after numerous tests reproducing the usage data of such packages, a tamper-evident cover of a new design has been developed, which easily adapts to the body of the case.

Suivant l'invention, le couvercle inviolable pour notamment un emballage plastique formant boite, au moyen de bandes détachables coopérant avec la jupe de la boite après emboîtement de leur borure périphérique en forme de U respectives, le dit couvercle étant ca ractérisé en ce qu'il comprend a' chacun de ses angles arrondis des oreilles détachables débordantes avec un profil extédeurarrondi et munis in térieurement de moyens conformés pour autoriser par pressiondUne part 1' engagement progressif du couvercle sur la Supe du corps de boite et d'autre part son clipsage en fin de couvez le détachement des oreilles par rapport à leur support étant effectué par une action de relevage de l'oreille par rapport au corps de boite provoquant la rupture simultanée de la totalité de la zone de rupture. According to the invention, the tamper-evident cover, in particular for a plastic packaging forming a box, by means of detachable strips cooperating with the skirt of the box after fitting their respective U-shaped peripheral boride, said cover being ca acterized in that it includes, at each of its rounded angles, detachable protruding ears with a rounded external profile and internally provided with shaped means for authorizing by pressure on the one hand the progressive engagement of the cover on the body of the box and on the other hand its clipping in end of cover the detachment of the ears relative to their support being effected by an action of lifting the ear relative to the body of the box causing the simultaneous rupture of the entire rupture zone.

Suivant une autre caractéristique, le couvercle présente des moyens autorisant d'une part son centrage par rapport au récipient et d'autre par l'empilement en hauteur avec d'autres couvercles aussi conformés en vue de leur stockage notamment. According to another characteristic, the cover has means allowing, on the one hand, its centering with respect to the container and, on the other hand, by stacking in height with other covers also shaped in particular for their storage.

Ces caractéristiques et d'autres encore ressortiront de la suite de la description. These characteristics and others will emerge from the following description.

Pour fixer l'objet de l'invention sans toutefois le limiter, dans le dessin annexé
La figure 1 est une vue en perspective d'un couvercle selon l'invention avant son montage et adaptation sur un récipient notamment une boite.To fix the subject of the invention without however limiting it, in the attached drawing
Figure 1 is a perspective view of a cover according to the invention before mounting and adaptation on a container including a box.

La figure 2 est une vue partielle en perspective selon la figure 1, l'emballage étant formé et verrouillé par son inviola bilité. Figure 2 is a partial perspective view according to Figure 1, the package being formed and locked by its inviola bility.

La figure 3 est une vue partielle en perspective montrant notamment l'agencement intérieur de l'un quelconque des angles du couvercle. Figure 3 is a partial perspective view showing in particular the interior arrangement of any of the angles of the cover.

La figure 4 est une vue sn coupe considérée selon la ligne 4-4 de la figure 2. Figure 4 is a sectional view sn taken along line 4-4 of Figure 2.

La figure 5 est une vue en coupe semblable à la figure 4, mais après arrachement des languettes d'angle de verrouillage. Figure 5 is a sectional view similar to Figure 4, but after cutaway of the locking angle tabs.

La figure 6 montre par une vue partielle en coupe le gerbage de plusieurs couvercles selon l'invention. Figure 6 shows a partial sectional view of the stacking of several covers according to the invention.

Afin de rendre plus concret l'objet de l'invention on le décrit maintenant d'une manière non limitative, en se référant à 1' exemple de réalisation des figures du dessin. In order to make the object of the invention more concrete, it is now described in a nonlimiting manner, with reference to the embodiment of the figures in the drawing.

On voit figure 1 le couvercle 1 selon l'inventions avant son montage sur un récipient R constituant généralement un corps de boîte 2 de toute forme volumétrique appropriée et correspondant à celle du couvercle 1. FIG. 1 shows the cover 1 according to the invention before it is mounted on a container R generally constituting a box body 2 of any suitable volumetric shape and corresponding to that of the cover 1.

D'une manière connue, le corps de boite 2 constitue périphériquement dans sa partie supérieure, une jupe 219 constituant un bourrelet de section transversale en forme de U renversé (figures 4 et 5). Le couvercle 1 forme également d'une manière connue une bordure périphérique 11 v profilée en U renversé, complémentaire à celle de la boite 2 pour permettre l'emboîtement du dit couvercle 1. In a known manner, the box body 2 constitutes peripherally in its upper part, a skirt 219 constituting a bead of cross section in the shape of an inverted U (Figures 4 and 5). The cover 1 also forms in a known manner a peripheral edge 11 v shaped in an inverted U, complementary to that of the box 2 to allow the fitting of said cover 1.

Selon l'invention, le couvercle 1 présente dans chacun de ses angles arrondis 12 des oreilles profilées 13 détachables par rap 6 port au corps lu couvercle selon une ligne de rupture 1, et ori- entées vers le bas. Ses oreilles 1 présentent un profil qui augmente à partir des points extrèmes de rattachement jusqu'au plan médian avec un profil extérieur en arrondi, comme cela apparaît bien aux figures du dessin. Ces oreilles, selon une autre caractéristique sont déportées selon un angle o( obliquement par rapport au plan vertical de chacune des faces du corps de boîte 2. According to the invention, the cover 1 has, in each of its rounded angles 12, profiled ears 13 detachable relative to port 6 to the body read cover along a breaking line 1, and oriented downwards. Its ears 1 have a profile which increases from the extreme points of attachment to the median plane with an external rounded profile, as can be seen in the figures in the drawing. These ears, according to another characteristic, are offset at an angle o (obliquely to the vertical plane of each of the faces of the box body 2.

Les oreilles sont ainsi établies de telle manière que l'utilisateur les saisisse obligatoirement dans leur plan médian selon la bissectrice de l'angle, et que pour assurer leur détachement, 1' utilisateur effectue une action de relevage de la languette par rapport au corps de boîte, provoquant de ce fait une action de rupture sur la totalité de la zone de rupture, assurant le détachement en une seule fois de l'oreille par rapport à son support.The ears are thus established in such a way that the user must grasp them in their median plane according to the angle bisector, and that to ensure their detachment, the user performs a lifting action of the tongue relative to the body of box, thereby causing a rupture action on the entire rupture zone, ensuring the detachment at one time of the ear relative to its support.

Ces oreilles 1 , pour être facilement détachables, présentent à leur endroit de raccordement avec la bordure périphérique 11 du couvercle, une multitude de perforations ou simplement une ligne d'amorce de rupture 16 (figures 1 et 2 > . Cette ligne d'amorce est sensiblement horizontale et à mi-hauteur de la paroi périphérique 11 et débouche de par ses parties extrêmes sur le bord pé riphérique inférieur de la bordure I
Le bord extérieur recourbé 15 de la bordure périphérique il du couvercle 1, à partir des angles duquel sont formées les oreilles 1 , peut également être déporté obliquement selon le même plan que celui desdites oreilles (figures 3 et 4).These ears 1, to be easily detachable, have at their connection point with the peripheral edge 11 of the cover, a multitude of perforations or simply a line of initiation of rupture 16 (FIGS. 1 and 2>. This line of initiation is substantially horizontal and halfway up the peripheral wall 11 and opens from its end portions on the lower peripheral edge of the edge I
The curved outer edge 15 of the peripheral edge 11 of the cover 1, from the angles of which the ears 1 are formed, can also be offset obliquely along the same plane as that of said ears (Figures 3 and 4).

Suivant une autre caractéristique, chacune des languettes est munie intérieurement de moyens M conformés pour autoriser par pression d'une part l'engagement progressif du couvercle 1 sur la jupe 21 du corps de boite 2 et d'autre part, son clipsage en fin de course. Cet ajustement est tel que, sauf arrachement de la totalité des oreilles d'angle 132 l'emballage fermé demeure inviolable (figure 4) et que, lorsque chacune des oreilles est détachée (figure 5), le couvercle 1 est normalement réutilisable pour s'emboiter de manière amovible sur la boîte 2. According to another characteristic, each of the tongues is internally provided with means M shaped to allow by pressure on the one hand the progressive engagement of the cover 1 on the skirt 21 of the box body 2 and on the other hand, its clipping at the end of race. This adjustment is such that, unless all the corner ears 132 are torn off, the closed package remains inviolable (FIG. 4) and that, when each of the ears is detached (FIG. 5), the cover 1 is normally reusable for removably fit onto the box 2.

A cet effet, chaque oreille d'angle arrondie 13 forme intérieurement une nervure en saillie 17 à partir de laquelle est formée perpendiculairement à partir de celle-ci et dans le plan médian de la languette, une rampe d'accès 1 s'amincissant en direction du bord inférieur arrondi 1 de la languette 13 (figure 3). For this purpose, each rounded corner lug 13 internally forms a projecting rib 17 from which is formed perpendicularly therefrom and in the median plane of the tongue, an access ramp 1 tapering in direction of the rounded lower edge 1 of the tongue 13 (FIG. 3).

Les rampes 1 permettent donc ltengagement progressif du couvercle jusqu'à son clipsage en fin de course au moyen des nervures I qui coopèrent avec le dessous du bord extérieur recourbé 15 de la bordure périphérique 11 du couvercle (figure 4).The ramps 1 therefore allow progressive ltengagement of the cover until it is clipped at the end of the stroke by means of the ribs I which cooperate with the underside of the curved outer edge 15 of the peripheral edge 11 of the cover (FIG. 4).

Suivant une autre caractéristique, le couvercle 2 présente intérieurement sensiblement dans le prolongement de chaque angle arrondi du bord intérieur recourbé 1 de la bordure périphérique i1 des bossages en saillie 11 . Ces bossages 1 C perpendiculaires au plan horizontal du couvercle permettent le centrale du couvercle en combinaison avec les parois intérieures du corps de la boite (figure 5) et permettent également le gerbage en hauteur de plusieurs couvercles selon les caractéristiques de l'invention (figure 6). Cela s'avère particulièrement intéressant pour le stockage des couvercles qui n'ont pas tendance à basculer les uns par rapport aux autres. According to another characteristic, the cover 2 has internally substantially in the extension of each rounded angle of the curved inner edge 1 of the peripheral edge i1 of the protruding bosses 11. These bosses C perpendicular to the horizontal plane of the cover allow the central cover in combination with the inner walls of the body of the box (Figure 5) and also allow stacking in height of several covers according to the characteristics of the invention (Figure 6 ). This is particularly advantageous for the storage of covers which do not tend to tilt relative to one another.

Les avantages ressortent bien de la description, en patticulier on souligne - La facilité de préhension des languettes d'angle détabhables - La fadlité et rapidité de clip sage du couvercle sur le réci
pient - La rapidité pour déverrouiller le couvercle du récipient pour
l'utilisation de languettes d'angle indépendants en apposition
à une bande détachable formée sur la totalité du pourtour exté
rieur du couvercle ; - La nouvelle esthétique du couvercle confèrée par les languettes
d'angle arrondie - La facilité de stockage des dits couvercles.The advantages are apparent from the description, in particular it is emphasized - The ease of gripping the detachable corner tabs - The fadlity and speed of wise clip of the lid on the container
pient - The speed to unlock the container lid for
the use of independent corner tabs in apposition
to a detachable strip formed on the entire outer periphery
laughing lid; - The new aesthetics of the lid brought about by the tabs
of rounded corner - The ease of storage of said covers.

L'invention ne se limite aucunement à celui de ses apodes d' application non plus qu'à ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées ; elle en embrasse au contraire toutes les variantes. The invention is in no way limited to that of its apodes of application any more than to those of the embodiments of its various parts which have been more especially indicated; on the contrary, it embraces all its variants.
