Definitions
- the present invention relates to a ré_j.] Li ⁇ .mi. rigid intended to be closed under vacuum by a lid for the conservation of foodstuffs or other products to be kept away from air, but which can be pasteurized or sterilized, the container after first opening can be closed using the original cover.
- container neck ring means the part of the neck of the latter arranged to receive the cover, said ring being able to include means for blocking the cover on the container.
- Containers and lids are already known for preserving food products.
- the cover of these containers is in the form of a disc with seal, placed on the rim of the ring of the neck of the container after forming an air vacuum in the latter.
- the container is opened by piercing the lid, which for this reason can no longer be used after the first opening.
- this type of packaging is equipped with a second cover formed with no screw to cooperate in screwing with the helical thread that comprises the neck of the container.
- This second cover is not provided with a seal, which does not allow a tight closure of the container after first opening.
- the second cover also has the function of ensuring, in combination with the vacuum prevailing in the container, the maintenance of the first cover on the collar of the neck, the internal face of the second cover by screwing the latter being applied against the first cover.
- This type of container with lid is also used for the preservation of vacuum-packed products, as shown in patent FR-A-664 507.
- the nets in addition to their function of ensuring in combination with the pins the maintenance cover on the drink, allow during the operation of the cover in the uncorking direction, the elevation of the latter and the formation of an air leak between the seal with which it is fitted and the drink which allows to break empty the container and authorize the unclogging.
- the vacuum prevailing in the container before first opening contributes to maintaining the cover on the rim. It is therefore necessary to control the value of this depression if one wishes to control the value of the torque to be printed on the cover to ensure the unclogging of the container.
- the vacuum is ensured by condensation of steam after first closing.
- This technique which, moreover, can only be used if the product to be conditioned can undergo a temperature rise without deterioration, does not allow obtaining pronounced air voids and does not allow control and rigorous control of the value of the depression in the container.
- the product is introduced hot into the container or steam is injected into the container just before closing.
- the second technique proceeds by air suction which allows good control of the value of the vacuum and uses for its implementation vacuum bells under which the containers are arranged.
- vacuum bells With containers whose closure is operated by screwing, it is very difficult to use vacuum bells. Indeed, a convincing result with the latter is only obtained if the cover has a relatively large freedom of vertical movement relative to the rim of the container on the one hand and if the cover by translation only can be applied to the rim of somewhere else.
- the cover is first maneuvered in the unscrewing direction to be positioned correctly on the neck of the container and then in the screwing direction to make a pre-setting leading the pins to engage under the nets. Therefore, the only freedom of vertical movement of the cover is given only by the functional clearances which remain low.
- the container with a lid for the vacuum storage of food products or other products to be kept away from air comprising an opening delimited by a neck ring provided with a flange to which the seal of the lid is applied, which before first opening is maintained on the rim only by the effect of the vacuum prevailing in the container, said ring also comprising an external surface of revolution developing under the rim
- the cover has at least one radial lug directed towards the external surface of revolution when the cover is placed on the neck and when said external surface of revolution, along a fraction of its perimeter, has at least one radial thickness having on the one hand an upper surface in the form of a ramp on which engages the lug or one of the lugs when the cover is maneuvered in the direction of opening and other p art a rear stop surface developing in a secant manner and perpendicular to the circular trajectory
- the ramp surface has a front or lower end remote from the rim and disposed under the circular trajectory of the lug and a rear or upper end, brought closer to the rim and disposed above this trajectory, the rear abutment surface at from the rear end of the ramp surface away from the rim.
- the lug (s) of the cover may be angularly separated from the ramp surface and will be located opposite a zone of the external surface of revolution of the ring free of any roughness likely to oppose the free translation of the cover on the collar ring.
- the advantage of this arrangement lies in the fact that a vacuum bell can be used to create the vacuum in the container. Indeed, the cover before forming a vacuum in the container and closing the latter, has a large degree of freedom in elevation so that the seal can be kept at sufficient spacing from the rim during the formation of the vacuum.
- the cover by its seal, can be applied to the rim, with slight pressure if necessary, to be placed in a sealing condition before the vacuum breaks in the vacuum bell.
- the value of the vacuum and consequently adjust the value of the mechanical torque to be printed on the cover to open the container may be large enough to prohibit the operation of the cover by young children and sufficiently low to allow this operation to the elderly.
- the opening of the container occurs by rupture of the vacuum which is produced by the formation of a leak between the seal of the cover and the lip of the neck ring. The formation of this leak due to the spacing of the cover relative to the rim, results from the engagement of the lug on the ramp in combination with the movement of rotation of the cover.
- the retention of the lid on the collar of the neck and therefore the tight closure of the container being ensured only by the effect of the vacuum prevailing in said container, any leakage between the seal and the collar, resulting from a manufacturing defect in an attempted fraud, etc. will cause the vacuum in the container to rupture and the lid to peel off.
- the merchant can therefore remove the product from its display and avoid offering products that are unsuitable for sale for marketing.
- the invention according to another of its aspects provides for a notch made in the rear part of the radial excess thickness in which, by compression of the seal and rotation of the cover, is brought the lug of the latter, said lug after relaxation of the compression coming to be applied against the horizontal upper face of the notch, which ensures the mechanical locking of the cover relative to the container.
- a hollow is formed in the radial excess thickness and this at spacing of the ramp and abutment surfaces, in which after the first opening can be engaged the lug of the cover to ensure the closure of the container. Before reaching the hollow, the lug must cross the full part of the extra thickness, which is done by force.
- FIG. 2 shows the neck ring of a container with extra thickness according to a second embodiment
- FIG. 3 shows the neck ring of a container according to a third embodiment
- FIG. 4 shows the neck ring of a container according to a fourth embodiment.
- the cylindrical skirt comes around the external surface of revolution of the neck ring 2 and the lug 6 forms a radial projection towards this surface of revolution.
- the neck ring has on its external surface of revolution at least one radial allowance 7 having an inclined upper surface 8 forming a ramp surface 1.
- This ramp surface intersects the circular path accomplished by 1 ' lug when the cover is rotated on the neck of the container. Furthermore, this surface of ramp occupies an oblique position relative to the trajectory of the lug.
- the radial allowance has a pointed tip front end corresponding to the lowest point of the ramp and a rear end corresponding to the highest point of the ramp, that is to say, that located closest to the rim 3.
- the front and rear ends of the ramp are preferably spaced angularly from each other.
- the front end of the ramp is located slightly below the lug trajectory while the rear end is located above this trajectory.
- the movement of the lug on the ramp in the opening direction takes place in the direction of the highest point of the latter.
- the slope of the ramp will be adapted to the value of the torque required to ensure the opening and will be sufficiently pronounced for the radial allowance 7 to occupy only a portion of the perimeter of the neck.
- the additional thickness 7 has a rear abutment surface 9 radial with respect to the neck parallel to the central axis of symmetry of the neck and intersects the circular path of the lug 6.
- This rear abutment surface is oblique with respect to the surface of the ramp and extends towards the bottom of the ring from the rear end of the ramp surface, the top of the ring being formed by the rim.
- the abutment surface 9 by its upper end is connected to the rear end of the ramp 8.
- a locking notch 10 in which, by elastic compression of the seal by axial thrust on the cover and rotation of the latter is engaged the pin 6.
- the notch 10 has an upper edge 11 forming right angle to the abutment surface.
- the notch 10 at a distance from the surface of the stop 9 has a bottom edge 12 developing perpendicular to the upper surface 11. This bottom edge constitutes a stop to the progression of the lug 6 in the notch 10.
- a recess 13 is made in the radial thickness 7 and this at a distance from the ramp 8 and abutment surfaces 9.
- the lug 6 of the cover 5 In this recess after first opening can be engaged the lug 6 of the cover 5 to ensure the main ⁇ hold of the latter on the rim 3 and therefore the almost sealed closure of the container.
- the lug 6 Before reaching the hollow, the lug 6 must cross the solid part of the extra thickness 7 which is done by forcing. opening of the container will also be effected by forcing, the lug 6 having to again cross the full part of the extra thickness.
- FIG. 4 a fourth embodiment of the radial allowance has been shown.
- This additional thickness is formed by a first thread, in a helix segment for example, forming the ramp 8 and a second thread in a straight segment for example, forming the stop 9.
- the container neck ring may be equipped with one or more radial thicknesses 7. In the case where only one radial thickness is provided, the latter may develop along a fraction of the perimeter of the ring only and the portion of the latter opposite to the additional thickness will be free of any protrusion.
- the cover Before first closing, prior to this operation, the cover will be angularly positioned with respect to the ring so that its single lug faces the portion of the ring free of protrusion. In this way, no obstacle is formed in the movement of the cover towards the rim during the first closure.
- the ring can be fitted with several radial excess thicknesses angularly spaced apart from one another and arranged at regular intervals from one another on the perimeter of the neck 2.
- the cover will have as many lugs as radial excess thicknesses.
- the lugs of the cover will be arranged opposite the intervals between the radial thickeners which are free of any protrusions against which the lugs could come, which would constitute an obstacle to the movement of the cover towards the drinker during the first closing.
- at least two radial thicknesses with notches or recesses will be provided, arranged on the neck symmetrically with respect to the central axis of the latter and the cover will have at least two pins, both arranged according to the same diameter.
