Definitions

  • the present invention relates to a sealed packaging box composed of a receptacle and a cover covering the latter, each comprising connecting means intended to cooperate to close the box in a sealed manner.
  • boxes are particularly useful for the temporary storage of food products in a refrigerator or other, such boxes or at least their principle is not suitable for receiving certain types of food products in particular very fragile products.
  • the present invention proposes to create a packaging box with a sealed closure making it possible to create a vacuum inside the box at the time of its closing in order to expel at least part of the air which remains between the product placed in the box and cover, and, on the other hand, for discharging excess liquids, a box which is easy to make and practical to use, in particular when it is closed for the first time, and which can be reused.
  • the edge of the cover is provided with a tamper-evident band terminated with a tear-off tab, this band connected to the edge by a preferential breaking line is hooked under the edge of the receptacle.
  • the passage is open towards the upper edge of the receptacle.
  • the passage has a shape which widens towards the inside of the receptacle or only towards the outside, by two flared parts separated by a neck.
  • the inner flared part of the passage in the receptacle has a V-shaped section and the cover closure member intended to be housed in this flared part has a diamond-shaped section with or without lips. .
  • the cover has a reinforcing and lifting rib.
  • the upper external part of the ring of the receptacle is formed by a conical surface to facilitate the positioning of the cover.
  • the inner annular rib of the cover has a rounded edge on the side cooperating with the ring-shaped edge of the receptacle.
  • the box according to the invention allows, thanks to its closure in two stages, to exert a certain pressure on the cover to evacuate the air and the excess liquids from the box through the passages then by a simple rotational movement (rotation which can be very low), to position and completely push in the cover and to keep it hooked, especially in the case of the first closure, by the tamper-evident security strip.
  • This box can be opened for the first time after tearing off the guarantee strip. It is possible to take a part of the contents of the box and in this case, it can be closed again with the lid, proceeding in the same way as at the time of the first closure except that in this case, there will have more warranty tape which is useless in most cases, the box being at the user or consumer.
  • this box is mainly intended to receive fragile food products such as caviar, spices, etc.
  • this box is not limited to the sole use in the food industry. It can also be used in other industries for the packaging and transport of fragile products, which must be conditioned in the absence of air or humidity.
  • the invention relates to a sealed packaging box composed of a receptacle (1) and a cover (2) connected to each other by connecting means which cooperate to close the packaging box tightly after having expelled the air manually or mechanically, the box being full to the brim or partly full.
  • the receptacle (1) consists for example of a frustoconical side wall (3) and a bottom (4).
  • this bottom can be produced at different heights (4A, 4B) according to the capacity of the receptacle.
  • the receptacle (1) is provided with a peripheral edge in the form of a sealing ring (5) crossed by passages (6) connecting the interior of the receptacle to the exterior. According to the embodiment shown, the passages (6) open onto the upper surface of the ring (5).
  • the cover (2) which covers the receptacle (1) consists of a bottom (21) provided internally with a rib (22) and bordered by an outer peripheral edge (23) with, if necessary, a reinforcement rib (24) and at the bottom a guarantee strip (25) provided with a tear-off tab (26) (see FIG. 9).
  • the cover (2) comprises shutter members or studs (27) which, when the cover (2 ) is placed on the receptacle, are housed in the flared parts of the passages (6) to close them from the rear, the front face of the passages (6) being closed by the peripheral edge (23) of the cover (2 ).
  • Figure 5 shows, schematically in the right half and the left half, the relative arrangement of the cover (2) and the receptacle (1) before and after insertion.
  • the upper edge of the receptacle (1) formed by a sealing ring (5) has a reinforced thickness relative to the side wall (3) of the receptacle (1).
  • This ring (5) has a cylindrical inner surface (51), an upper surface (52) located in a horizontal plane and an outer surface (53) inclined in a truncated cone at the top, continuing at the bottom with a cylindrical surface ( 54) projecting forming a shoulder (55) with the outer surface (31) of the wall (3) of the receptacle (1).
  • FIG. 6 The sectional view of Figure 6 also shows the shape of a passage (6) communicating the interior of the receptacle (1) with the outside.
  • the passage (6) which in this embodiment opens into the upper surface (52) of the ring (5), consists of an inner part (61) flared, continuing with a narrowed part (62) forming a neck then an outer part (63) which can also be flared.
  • section of the passage (6) is the same over its entire height to facilitate the manufacture by molding and allow the establishment of the shutter member (27) of the cover (2) as will appear below. after.
  • this passage (6) can have the form of a venturi as above or else a form of hearing, valve or valve allowing the passage of air or liquid, from the interior of the receptacle towards the 'outside.
  • the height of the passage (6) is chosen so that it is capped by the edge (23) of the cover even when the guarantee strip (25) has been torn off.
  • Figure 6 also shows, in detail, the shape of the cover (2).
  • This consists of a bottom (21) provided on its inner surface with a sealing rib (22) located in a position such that when the cover (2) is pressed, it comes behind the ring sealing (5), against its inner surface (51).
  • This rib has a trapezoidal section with a rounded outer edge to facilitate its positioning behind the sealing ring.
  • This peripheral sealing rib (22) is completed by a sealing member or stud (27) intended on the one hand to serve as a support and on the other hand to come into the flared inner part (61) for shut it off.
  • This shutter member (27) is of cylindrical shape and of section corresponding, at least for the part concerned, to that of the flared inner part (61) of the passage (6).
  • the shutter member (27) projects beyond the flared part (61) of the passage (6) for reasons of solidity.
  • the cover (2) is provided with an edge (23) forming a skirt of sufficient height to cover the sealing ring (5).
  • the edge (23) is provided in its lower part with a guarantee ring (25) forming a step (251) with the inner surface (231) of the edge. At this recess (251) there is a rupture line (252) for tearing off the guarantee strip (25).
  • the height of the edge (23) and the importance of the step (251) are chosen so that this assembly can closely cover the sealing ring (5), as shown in FIGS. 8 and 9.
  • the shutter members (27) serve as a support for deforming the bottom (21) of the cover (2), for expelling air and / or liquid, it is not only necessary that these members be sufficiently resistant , but that they are also regularly distributed. As their number is identical to that of the passages in which they are housed, it is advantageous to have at least three sets of passages (6) / shutter members (27).
  • closing the box consists of putting the cover (2) in place, in a partially closed position, then expelling the air and / or the liquid, then completely closing the box by putting in places the tamper-evident security strip (25).
  • the passages (6) and the shutter members (27) are in a position slightly angularly offset so that the lower surface (271) of the members (27) comes to bear against the upper surface (52) of the 'ring (5) and limits the driving movement.
  • the passages (6) thus remain clear at the rear and the edge (23) or the guarantee strip (25) also do not close the passages (6).
  • the two sectional views made one in line with a passage (6) and the other in a different location, show on the one hand the close fitting of the edge (23) of the cover (2) on the ring (5), the rib (22) coming from the other side and on the other hand the shutter member (27) in the part flared (61) from the passage (6).
  • the packaging boxes described above can be produced in different forms and capacities, either single or multiple. They can be used for the packaging of industrial or food products and in particular fragile foodstuffs such as caviar, which must be conditioned in the absence of air.
