Definitions
- the invention relates to packaging packaging, in particular products food, made of plastic.
- plastic packages are widely known, especially for packaging of food products. Among these, there may be mentioned a package described in document FR-A-2 707 951.
- This package consists of a rigid container, which has an opening delimited by an inverted U-shaped peripheral flange, and intended to receive a cover with a peripheral rim, complementary shape, so also inverted U-shaped, intended to be fitted on the peripheral rim of the tray.
- the seal between the tray and the lid is ensured by means of two strips annular, extending the respective peripheral edges of the tray and the cover, welded together over the entire outer peripheral edge, and presenting a tear notch, to allow the posterior opening of the lid, when the first use.
- a package also plastic, having a container itself, closed by a lid, with, as in the previous example, joining by welding of the flanges extension and presence of a zone of least resistance of the lid.
- the lid is detached from its peripheral edge, then can be closed by interlocking it, within the container, presenting to this effect a shoulder cooperating with a shoulder which is also provided with lid.
- the invention proposes a packaging of the type in question, allowing first of all to optimize its watertightness before use, especially with gas, so that it can increase the retention period significantly.
- the packaging according to the invention aims to optimize the inviolability, well apparent, and in addition, allows to be molded in one step.
- This objective is realized by separating the functions of sealing and opening properly called.
- the peripheral edge of the disk is provided with a radial rib extending between the implantation site of the gripping member and the peripheral rim of the lid.
- the invention aims to divide the fastening functions, by welding or gluing, lid on the container, and opening said container. Indeed, it is not properly speaking the lid that is open, so far as its flange device remains permanently glued or welded on the peripheral edge of the container, but the central shutter disk that is likely to be open. This by doing so, the sealing of the contents of said container is substantially optimized, especially with respect to the containers of the prior art. In addition, there is a single piece, in which said disc is not separated from the assembly constituting lid and container.
- this line of least resistance is quasi-continuous and has interruptions that can be hinged articulation of the disk on the peripheral rim of the lid.
- this line of least resistance is actually constituted by a succession of points of attachment or pins, solidarisant to regular intervals the two parts of the flat portion of the peripheral rim of the cover, the areas of said flat portion of the cover extending between the points fasteners or pins are free of any material.
- FIGS. 1 and 2 an embodiment of FIG. the packaging package according to the invention.
- this package is more particularly intended to receive a fresh food product, salad type etc ...
- a rounded container (1) in which the described example, of symmetry of revolution, having an upper opening (6), intended to be closed by a cover (2).
- the upper rim of the container (1) has an inverted U-shaped section, such that that can be observed in Figures 12 and 13.
- this particular arrangement comprises an internal branch (7), a outer branch (8), the two branches being interconnected by a portion substantially horizontal (9).
- the inner branch (7) in fact extends the side wall of the container (1), the whole resulting from the molding, in particular by injection.
- the lid (2) consists of a peripheral flange (3) designed to fit on the peripheral rim of the container (1), and further comprises a disc (4) closing the opening (6) of the container (1).
- the disc (2) is provided, in the vicinity of its periphery, with a gripping member (5), constituted in this particular case by a substantially circular ring, the two ends of which are secured to the base of the disc. closing (4) in the vicinity of the peripheral edge (3) of the cover (2).
- the gripping ring is systematically oriented in a plane parallel to the disk (4), except during the opening phases. It returns after such phases to its natural position in said plane parallel to the disc (4), due to the elastic effect of the plastic material that constitutes it.
- FIGS. 3 to 6 a first embodiment of FIG. cover (2) according to the invention.
- the lid according to this first form of realization, therefore has a flange (3) protruding from the general plane of the disc (4) (see Figures 4 and 5).
- the peripheral rim (3) of the lid (2) is also in U-shaped section inverted, so as to be able to fit on the peripheral rim of the container (1), as can be clearly seen in Figures 12 and 13.
- the outer leg (16) of the peripheral rim (3) of the lid (2) is provided with an inwardly directed projection (18) for promoting cooperation between the outer branch (16) of the cover (2) and the lower end of the branch external (8) of the container (1).
- the flat part (17) of the peripheral rim (3) of the lid (2) has a zone of least resistance (10), substantially circular.
- This area of least resistance is obtained by reducing the amount of material to this level, as can be observed, especially in Figure 6, or Figure 12.
- This line of least resistance (10) is substantially continuous, except at the level of two zones (11), substantially diametrically opposed to the implantation zone of the gripping ring (5).
- These zones (11) are intended to form hinges during the opening of the disk (4).
- the zone of the peripheral rim located in line with the gripping ring (5) has a discontinuity consisting of a beak (12), oriented in the direction of the center of the disc (4), and intended to promote the initiation of rupture of the line of least resistance (10).
- the peripheral edge extends at the beak (12) by a rib (13), radial, extending substantially over the entire height of the peripheral rim, as can be observed, in particular Figures 5 and 6.
- This rib is in a way an extension of the beak (12).
- the rib ends substantially on the disk between the two zones implanting the ends of the gripping ring (5) on the disc (4) (see Figures 5 and 11).
- This rib is intended to concentrate the tensile force exerted by the ring of gripping (5) at the spout (12), and thus promote the breaking of the line of less resistance (10).
- the hinge effect is increased by optimizing the resistance mechanics of pulling the disc out of the peripheral rim. It is not uncommon indeed that excessive traction exerted by the user causes the total tearing of the disk.
- the line of least resistance (10) is replaced by the absence of any material at this level. Only pins (19) join at regular intervals the portions of the flat portion (17) of the peripheral rim of the cover (2).
- the hinge effect is maintained here by pins, in appropriate places, always in substantially diametrically opposite position with respect to the gripping ring (5), and the principle of the rib also remains the same.
- the first embodiment is more particularly suitable in the frame of a welding attachment of the peripheral rim (3) of the cover (2) on the peripheral rim of the container (1)
- the second embodiment is all particularly used in the context of a joining by bonding.
- ultrasonic welding in particular, intervenes substantially in an annular portion (20) external to the portion respectively (9) and (17) peripheral rims of the container (1) and the lid (2).
- the bonding (21) takes place substantially over the entire flat part, such that can see it in figure 13.
- This method of joining makes it possible to confer on the contents of the container a perfect including gas, during a specified period, which is one of the most goals sought by the present invention.
- the assembly constituted by the lid (2), the shutter disc (4) and the gripping member (5) is monoblock and directly obtained from molding by injection.
- fixation system implemented and in addition the principle of the zone of less resistance also confer tamper resistance on the container.
- the opening of the container is very easy by the user, and is done in one operation.
- the gripping ring (5) is not secured to the base of the disc (4), but at the level of top of its peripheral rim, in an area immediately adjacent to the beak (12).
- This embodiment avoids the implementation of the radial rib (13), and thus simplifies the realization of the package of the invention.
- this ring can be shaped so as to extend in two planes as can be clearly seen in Figures 15 and 16, which is thus to allow its folding on the bottom of the disc (4), and corollary, to promote the stacking of the packs according to the invention on top of each other.
- packaging of the invention is in one piece, filling the different functions devolved to it, including tight closure, and different opening and closing operations after first use.
