- PROCESS FOR SEALING A CONTAINER OR PACKAGING IN A SEALED AND HERMETICALLY MANUFACTURING METHOD SEALING MEMBER FOR SUCH A PACKAGING OR CONTAINER AND CONTAINER OR PACKAGING OBTAINED BY THIS PROCESS.
- the invention relates to a method for sealing and hermetically sealing a package, or in general all types of container. It also relates to a member intended to lead to this sealed and hermetic closure. Finally, it relates to such a container or packaging provided with this closure member.
- the invention uses a cover, attached to the level of the closure member.
- This closure may consist of a cover with reversible closure, but may also consist of a repositionable adhesive, releasing an orifice closed by a cover.
- one of them consists in producing a rigid preform, typically made of a relatively thick cardboard, or even aluminized, that is to say receiving an aluminum film, preform to which the final shape is given. that we want to see adopted by the packaging.
- the packaging thus produced is turned over, then filled with the agro-food product that it is intended to contain and finally, is closed by a traditionally heat-sealed bottom, this fixing being further optimized by a stamping towards the inside of the preform. , so as to constitute a reinforcing shoulder for said bottom.
- the body of the container or of the packaging is rigid, so that the film constituting the cover is put in place relatively easily.
- This process consists in starting with a flat or sheet, intended to constitute the body of the packaging.
- This sheet is given the desired shape by means of a mandrel and of pliers coming to take the two extreme edges of the sheet, in order to make them overlap edge to edge, typically over a width of 2 millimeters, and to ensure their joining on their entire height, this joining being typically carried out by ultrasound, or even by gluing or heat-bonding.
- This sheet is therefore made of synthetic material, or even of cardboard, treated so as to allow this ultrasonic welding or heat sealing.
- the body thus produced receives at its base a bottom, typically consisting of a cup, also made of a synthetic material, the shape and dimensions of which correspond of course to the shape and dimensions of the body produced during the previous step, and the periphery of which is provided with a groove within which is intended to be inserted the lower end of said body.
- a bonding or welding phase is carried out in order to ensure the required tightness and hermeticity at this level.
- the packaging is returned and filled. To do this, it is kept in shape by means of pliers or a system of external pliers, taking into account the relative flexibility of the constituent walls of the body. Then it is closed by means of a cup similar to that constituting the bottom, generally provided with an appropriate closure system, and attached and secured in the same manner as the latter.
- this embodiment makes it possible to achieve a multiplicity of forms, since one starts from a flat, to which one can give the desired shape and dimensions, and that the final shape then results from the shape of the cups.
- the object of the invention is to overcome these various drawbacks.
- This process for sealing and hermetically sealing a packaging or container the body of which is produced from a flat sheet or sheet of any material, and in particular cardboard, synthetic material, paper or even metal, said flat being shaped according to the desired profile, consists in attaching a rigid peripheral ring or base intended to be closed by a tight and hermetic seal at the circumference of the tip of said container or of said packaging, intended to constitute the opening access or emptying of its content.
- the invention consists in attaching to the opening of a container a rigid part capable of receiving a seal, suitable for ensuring the tightness and hermeticity of said container.
- the ring or peripheral base is provided with the cover prior to its positioning at the opening of the container.
- said ring is first of all secured at this opening, then the cover is integrated at the level of the ring.
- the bottom of such a packaging is constituted by a cup made of synthetic material, wood or cardboard, and whose shape and dimensions correspond to the desired final shape of the packaging, said cup being provided at its periphery with means able to cooperate with the lower end of said sheet so as to be able to be secured thereto in a sealed and hermetic manner by bonding or welding, the opposite end piece receiving the ring provided with the tear-away or retractable seal.
- this nozzle receives a cover with reversible closure.
- a cover proper is articulated on the base or peripheral ring.
- This cover can be obtained from molding, and formed a whole with the ring or peripheral base, the assembly then being provided with a hinge formed at one of the edges of the ring, or else the cover can be clipped on one of the edges of said ring, these two elements then being provided with the necessary complementary members.
- Figure 1 is a schematic sectional representation of an embodiment of the invention with the cover closed
- Figure 2 is a similar view, cover open.
- Figure 3 is a very schematic plan view of a cover according to the invention.
- Figure 4 is a schematic representation of the different steps of placing the cover within the cover according to the invention, of which Figure 5 is a representation of a detail seen in plan.
- Figure 6 is a schematic representation of a variant of the embodiment of Figure 4. The following description relates more particularly to the field of food products. It is however understood that the invention cannot be limited to this single application.
- FIG. 1 a schematic cross-sectional representation of a container according to the present invention.
- This container bears the general reference (1), and in the embodiment described, consists of a vertical parallelepiped body (2), the two ends of which. respectively constitute the bottom (3) and the access nozzle inside the container (10).
- the body (2) of the container consists of a sheet or flat, made of plastic, capable of being printed by a traditional process such as, in particular screen printing, flexography, and in general, all processes d 'impression.
- This sheet the dimensions of which are determined as a function of the desired volume of the final packaging, is joined edge to edge at two of its extreme edges, welded by a traditional welding or gluing process, in order to constitute a body of parallelepiped shape.
- this shape is not acquired, taking into account the relative flexibility of the material which constitutes it, and consequently, the buckling phenomena likely to result therefrom.
- the desired final shape will be given to it by the installation of the constituent elements of the bottom and of the access nozzle.
- the bottom (3) of this body (2) is in fact constituted by a cup (3), therefore of corresponding dimensions and having the shape of a square.
- the periphery of this cup (3) has an annular groove (4) directed upwards, and intended to receive the lower edge of the body (2) thus produced.
- This cup is made of synthetic material, or of wood or cardboard.
- the open end (10) of the packaging thus produced intended to constitute the means of access to the interior thereof and of evacuation of the content that it is intended for. to be received, is closed by means of a cover (5) described in more detail below.
- This cover basically comprises a rigid peripheral ring (7), also of square shape, the dimensions of which correspond to those of the body (2).
- This ring (7) is attached to the upper end of said body by any traditional means, such as in particular bonding, heat sealing or even welding.
- this ring could be attached in the vicinity of the end considered of the body, but inside, outside, or even on horseback on either side of the end of said body.
- This peripheral ring is made of plastic, and has a hinge (9) for articulation of the actual cover (6), also of square shape.
- the assembly constituted by the cover (6), the peripheral ring (7) and the hinge (9) is produced by injection molding.
- the actual cover (6) and the ring (7) are produced completely independently, the cover being clipped onto one of the edges of said ring after the latter has been placed on the body (2).
- the ring (7) incorporates a cover (8), intended to seal the contents of the container (1).
- a cover (8) intended to seal the contents of the container (1).
- the user removes the cover (8) to gain access to the interior of the packaging.
- Figure 2 a view similar to Figure 1, wherein the cover (6) is in the open position.
- the packaging (1) it is possible to shape the packaging (1) according to a multiplicity of shapes and dimensions.
- the desired volume of the packaging can also be modified at leisure by simply modifying the dimensions of the starting sheet or flat constituting the body (2) of the packaging.
- a sheet can be printable at will, it also becomes possible to communicate in a variety of ways.
- a robot manipulator (13) grips them, in l 'species by group of eight, and their positioning on a conveyor (12) in four series of two covers.
- a manipulator arm (14) takes the covers in groups of two by means of suction cups, and positions them on a turntable (15) (Phase A), at a female socket coming to be fitted within the opening defined by the peripheral ring (7), and this, in order to ensure the maintenance in a horizontal position of these.
- This turntable (15) is motorized by means of a stepping motor, so as to convey the pairs of covers directly above the various successive stations, necessary for the installation of the lids.
- phase B the pairs of covers are routed directly above two identical barrels (17) storing the solid covers.
- the cover located at the lower end of the stack contained in each of the barrels is apprehended by a jack (19) with vertical travel, provided with suction cups, passing through the opening defined by the peripheral ring (7), then placed at the level of the ring (7), and more precisely at the level of an internal shoulder (not shown). To do this, at this level, the vacuuming of the suction cups is cut, thus allowing the release of the seal.
- the latter is rigid enough to rest on the shoulder mentioned, in the absence of any other constraint.
- each of the two covers is kept blocked by an underlying suction cup (20) at the level of the cover, so as to allow the flap of the cover (6) on the peripheral ring (7).
- This operation is carried out by means of a manipulator arm (not shown).
- the cover (6) is clipped onto the ring (7) during the subsequent step (phase E), then, after further rotation of the plate (15), the pair of covers (5) is grasped by a manipulator arm (21), which deposits said covers on a conveyor (16) by means of suction cups (phase F).
- This cover is of traditional invoice and typically consists of a complex consisting of an aluminum film surmounted by a polyethylene film, said polyethylene film being intended to allow fixing by heat sealing or heat sealing at the internal face of the ring or peripheral base (7) of the cover (5).
- this cover is placed directly on the production site, that is to say when filling the container intended to receive the cover.
- the covers (5) obtained after injection are stored in a vibrating bowl (22), then conveyed to the level of a conveyor (23), at the end of which a manipulator arm (24) ensures their positioning at the level of the upper end of a package, the lateral body (2) of which alone is produced, said body being held in place at a rotary plate (15) by members not shown.
- each cover is fixed to the upper end of the body (2) by means of the peripheral ring (7), and this by gluing or heat-bonding, or even by welding.
- the cover is not fixed in its entirety (5), but only the rigid peripheral ring (7), also by gluing, heat sealing or by welding.
- a mandrel (25) with vertical stroke rises through said lateral body (2) to come and take the seal located at the lower end of a barrel (17), to come and place it at the level of the peripheral ring (7) of the cover (5), and more precisely, at the level of an internal shoulder, formed within the peripheral ring (7).
- a welding head secures said seal at the internal face of the peripheral ring (7).
- the actual cover (6) when required, is folded down and clipped onto the ring (7).
- the packages (25) are conveyed at the level of the filling line (not shown).
