- a container is intended to contain a liquid or food.
- such products with a specific form can be bottles intended for the agrifood sector, cleaning products and cosmetics (or FHPC for "Food, Home / Health and Personal Care”).
- a first drawback lies in the shape of a bucket dedicated to a specific format of product. During a change of production, it is then necessary to replace all the buckets of the products formerly produced, by new buckets shaped to receive the new products to be treated. Such an operation results in a significant loss of time. In addition, it is easy to understand the storage space required for unused buckets, as well as the referencing problems to find them when changing production. In addition, depending on the number of formats to be processed, the cost Buying and replacing each type of bucket by size is expensive.
- chassis with a receiving base intended to support the bottom of a product
- a means for gripping a product comprising a clamp provided with two movable jaws between a spread position and a tight position.
- each jaw may have a horizontal hollow shape at least in the upper part and in the lower part, so as to maintain the said product on either side in at least two upper support points and in the minus two lower support points.
- the holding device can include elastic return means for each jaw from the separated position to the constricted position.
- Said base can be mounted movable in rotation relative to said chassis.
- Said base can be adjustable vertically with respect to said chassis.
- Each jaw may include a shape memory coating at least at the levels of at least one of the upper and lower support points.

- the base 4 has a receiving surface which may or may not be flat, horizontal or inclined.
- the receiving surface of the base 4 can be curved, namely that it has a recess allowing in particular to receive in a more adjusted manner a convex bottom of a product 1.
- Such a recess can include inclined side walls, generally forming a truncated cone, ensuring the insertion adjustment of the bottom of a product 1 but also of its peripheral walls.
- Said base 4 can be covered at least partially with a non-slip coating, limiting the sliding of the walls of the product 1 in contact with it.
- said base 4 is mounted movable in rotation relative to said chassis 3.
- the upper part of the device 2 intended to receive a product 1 can rotate, in order to orient the product 1 differently.
- An example of rotation of the base 4 is shown in one direction in FIG. 1.
- Such a rotation of the base 4 takes place in principle around an axis extending vertically.
- Such an axis is mounted on the chassis 3, substantially at its center and preferably aligned with the center of gravity of the holding device 2.
- the rotation can be performed at an angle of 90 °.

- the invention makes it possible to overcome any instability or imbalance of the product 1, when its width extends along the conveying direction, especially when undergoes accelerations or decelerations.
- each device 2 during the passage of each device 2 at a location and / or along a portion of an installation, the cooperation of said systems applies a rotation to each base 4 at an angle provided and determined beforehand. It is then possible to modify the orientation of a product 1 relative to the device 2 along the industrial line, making it possible in particular to orient the products 1, for example oblong with their length extending transversely relative to the conveying direction, so as to be able to bring several devices 2 together to transport more products on an identical conveying portion.
- the device 2 may include elastic return means applied to the base 4 to cause it to return to an initial angular position.
- said base 4 is adjustable vertically with respect to said chassis 3. Such an adjustment can be carried out manually by an operator, raising or lowering each base 4 of each device 2, but preferably in a controlled manner, in particular by through a dedicated engine or through a mechanical system cooperating with a complementary mechanical system of the installation or installations along which the device 2 is conveyed.
- the cooperation of said systems can apply the raising or lowering of the base 4 relative to the chassis 3. It it is then possible to modify the vertical position of a product 1 relative to the device 2 along the industrial line.

- the device 2 comprises a means 5 for gripping a product 1.
- the means for gripping 5 comprises a clamp provided with two jaws 50, 51.
- the jaws 50, 51 are movable between a separated position and a constricted position. In the separated position, the jaws 50, 51 open to leave enough space to extract or introduce a product 1 between the clamp, with or without play between the interior surfaces of the jaws 50, 51 and the peripheral walls of product 1. In the closed position, the jaws 50.51 close until a product is pinched 1. When empty, without product 1, the jaws 50.51 can abut one against the other or be spaced apart compared to each other.
- Such mobility can take place symmetrically or not with respect to a vertical plane, in particular the vertical median plane of the device 2.
- only one of the jaws 50 (or 51) is provided movable relative to the base 4, the other 51 (or 50) being fixed.
- the device 2 can comprise elastic return means for each jaw 50,51 from the separated position towards the position tightened.
- This elastic reminder automatically applies pressure on either side of a product 1, ensuring that it remains in opposition, as if it were gripped from two sides.
- the applied force can be adjusted manually or in a controlled manner by modifying the elasticity of said return means.
- the mobility of jaws 50.51 makes it possible to adapt the distance between the jaws 50.51 and the nip to be applied to a product 1, depending on its shape, but also on other characteristics such as its rigidity.
- the device 2 makes it possible to adapt to different forms of products 1, including specific forms.
- each jaw 50.51 is mounted to rotate freely around a pivot point 6, allowing each jaw 50.51 to tilt and ensure that it comes into contact with the walls of the product 1 to be clamped, even if said walls are not straight or vertical. Indeed, around each pivot point 6, each jaw 50.51 can rotate at an angle sufficient to tilt according to the slope of the wall of the product 1 located opposite each jaw 50.51 .
- each pivot point 6 receives an axis extending horizontally or substantially horizontally, the axes of the pivot points 6 of the jaws 50, 51 being parallel, preferably in the same horizontal plane.
- Each jaw 50, 51 rotates around its axis centered on each pivot point 6.
- Each jaw 50, 51 has a concave vertical shape, so as to maintain said product 1 in at least one upper fulcrum and in at least one lower fulcrum. Thus, each jaw 50, 51 comes into contact at the top and bottom of the product 1, which then finds itself gripped on either side at at least four points.
- the concave shape of the jaws 50, 51 is understood to be on the interior side facing each other.
- the upper and lower parts of each jaw 50,51 are offset towards the inside of the clamp, relative to the center of each jaw 50,51.
- This concave shape can be rounded or made up of segments.
- the device 2 can include arms 7 supporting the jaws 50, 51.
- Each arm 7 extends vertically or substantially vertically.
- the upper distal end of each arm 7 receives the pivot point 6 of each jaw 50,51, in particular said axis mounted free in rotation relative to each arm 7 and / or relative to the corresponding jaw 50,51 .
- each arm 7 can be mounted mobile on the base 4 or the chassis 3.
- Each arm 7 can be provided mobile in translation, in rotation or a combination of the two. Consequently, it is the arms 7 which are mounted movable in movement towards the inside or towards the outside of the device 2, in order to confer approximation or spacing to the jaws 50, 51.
- actuation in approach or spacing of the jaws 50, 51 can be controlled mechanically by a suitable system, at the passage of a place or along a portion of one or more installation (s).
- the spacing of the jaws 50.51 can also be carried out by introducing a product 1, by pushing in force, and conversely during the extraction by pulling the product 1 until it is released from the device 2, the jaws 50.51 are approaching under the effect of elastic recall. Consequently, the opening or closing of the jaws 50, 51 is freed from any intervention by an operator manually on each device 2.
- Each upper fulcrum is located above the pivot point 6, while each fulcrum lower is located below.
- each upper support point can be located above the center of gravity of the product 1, while each lower support point is located under said center of gravity.
- the jaws 50, 51 can be mounted on the chassis 3.
- the clamp is retained by clamping it can be carried out in the direction of the greatest length of the base of the product 1.
- each jaw 50, 51 comes to bear on either side, at each edge of the length of the product 1.
- its clamping can be carried out according to the diameter or the diagonal.
- the product 1 can be clamped along the largest diagonal or the largest internal dimension. It is also possible to enclose the product 1 differently, depending on its diameter, its side or its smallest diagonal.
- each jaw 50, 51 can have a horizontal hollow shape at least in the upper part and in the lower part, so as to hold the product 1 on either side in at least two upper support points. and at least two lower support points.
- each jaw 50.51 includes product 1 on either side with respect to a vertical plane, ensuring at the top as at the bottom, a support on its front and rear faces (ie on the front and back) .
- the hollow of the jaws 50, 51 can be rounded or in the form of segments. It is formed in the inner face of each jaw 50,51, recessed inward. As can be seen in the figures, in particular in FIG. 2, the jaws 50, 51 can have a hollow shaped like a V.
- the product can be grabbed laterally and transversely, improving its retention within the device 2.
- the tilting combined with the hollows of the jaws 50, 51 makes it possible to adapt the retention by clamping to very varied shapes, in particular by pinching very specific shapes, such as for example with oval base or elliptical, as well as the edges of polygons, but also the projecting edges even rounded, such as for example a section of calisson type.
- each at least one upper and lower support point of each jaw 50, 51 can constitute a support surface in a plurality of support points, depending on the shape of the product 1 at these support levels and according to the conformity of each jaw 50.51.
- each jaw 50, 51 may include a non-slip coating 8 at least at the levels of at least one of the upper and lower support points.
- a non-slip coating can be made of a flexible or elastic material, such as synthetic or natural rubber. This coating is applied to the internal face of the jaws 50, 51. It can protrude internally, in particular in the form of bars 8 made of non-slip material, as can be seen in FIGS. 2 to 4.
- each jaw 50, 51 can comprise a coating with shape memory at least at the levels of at least one of the upper and lower support points.
- the entire surface of each jaw 50, 51 is covered with a shape memory material.
- a shape memory material has an elasticity allowing its deformation in contact with the walls of a product 1 at the time of its clamping. The resilience of this material allows conservation of the imprint of a product 1, for a given period, even after its extraction from the device 2.
- the time required to return to the original shape of this material can be provided for a duration corresponding to the time necessary for a change of production to a different format of product 1, for example from a few seconds to a few minutes.
- the device 2 is a device for holding a single product 1.
- the products 1 are conveyed individually within a conveying installation and the distance and / or the arrangement between successive products 1 can easily be modified according to the treatments to be given to products 1.
- the clamp can comprise exactly two jaws 50, 51 movable between a spread position and a tight position, so that it is possible, if necessary, to hold or release a product 1.
- the two jaws 50.51 of the clamp face each other.
- the device 2 is in principle a device 2 for holding a single product 1 comprising a clamp provided with exactly two jaws 50, 51.
- the mobility between the two jaws 50, 51 to open or close the clamp is carried out according to a horizontal translational movement.
- at least one jaw 50,51 can be mounted free in translation relative to the base 4 in a horizontal plane in the direction of the other jaw 50,51.
- the two jaws can move towards and away from each other by means of respective horizontal translational movements.
- At least one of the jaws 50,51 can be fixed to the base 4 via at least one horizontal slide directed from one jaw 50,51 towards the other.
- the two jaws 50, 51 are thus mounted.
- the device 2 is particularly suitable for being able to maintain products 1 of very different widths. Indeed, whatever the width of the product 1 to be maintained, the jaws 50, 51 will be more or less close to each other, but always at the same height. Therefore, even for products 1 of very different widths, the at least one upper fulcrum and the at least lower fulcrum can respectively be located above and below the center of gravity of these products 1 when they are maintained by such a device 2, which thus ensures optimum maintenance.
- the device 2 is a device 2 for maintaining a single product 1 compatible with a plurality of different forms of products 1, within an industrial production and processing line for products 1, including:
- a means 5 for gripping a product 1 comprising a clamp provided with exactly two jaws 50, 51 movable between a separated position and a tightened position;
- the device 2 is characterized by the fact that:
- Each jaw 50,51 is mounted to rotate freely around a pivot point 6 and has a concave vertical shape, so as to maintain said product 1 at at least one upper bearing point and at least one point of lower support, and
- At least one of the two jaws 50, 51 is mounted movable in translation relative to the base 4 in a horizontal plane, so as to allow passage between said separated and tightened position.
- the device 2 ensures improved maintenance of a product 1, by adapting to several formats and several shapes, even specific and complex.
