Description

Device for improving the grip of a container and container

  provided with such an anti-slip device.

  The invention relates to containers for the packaging and dispensing of a fluid product and more particularly, but not exclusively, those for containing an oxidation dye product.

  In one mode of using the oxidation dye products, an oxidation dye precursor is mixed with an oxidizing composition to obtain a ready-to-use composition.

  In this regard, it has been proposed to condition the oxidant in tube-shaped containers in order to make the mixture easier to achieve.

  In particular, the tubes used for conditioning the oxidizing composition generally have a body provided with a closed end and an open opposite end forming a neck. The neck may be provided with a thread on which can be screwed a tube containing the oxidation dye precursor, so that it is easy to transfer the content to the conditioning tube of the oxidizing composition. Therefore, this tube can also be used to distribute and distribute the product in the hair.

  However, gloves are generally used for handling such containers and in particular when using the coloring products they contain. It has been found that the use of gloves, which are quickly soiled, to handle the containers does not make it possible to ensure that the container is effectively taken. This is particularly the case when the user has to squeeze the container to dispense the product. This disadvantage increases when the container is configured in the form of a tube whose closed end is obtained along a transverse closure line, so that the mutually opposite walls of the tube form a relatively open angle.

  In view of the foregoing, there is a need to improve the grip of the containers for packaging and dispensing products, without modifying existing molds and tools for producing the containers and with negligible additional cost.

  The invention thus relates to a device for improving the grip of a container containing a product to be applied to the hair, in particular a hair dye product.

  According to a general characteristic of this device, it comprises fixing means for mounting the device on the container, a first portion intended to be applied substantially against a side surface of the container when the device is mounted on the latter and a second portion configured relative to the first portion so that when the device is mounted on the container, the second portion extends from said first portion transversely to a longitudinal axis of the container.

  The second portion thus constitutes an axial abutment.

  The presence of such an axial abutment provides support for the hand of the user. This stop may, for example, be inserted between two fingers of the user thus preventing any slippage of the container and to ensure its grip.

  Such a device constitutes an independent element and separate from the container on which it is mounted, so that the invention can be made without making any modification to the mold used for the realization of the containers.

  According to a first embodiment, the device comprises a rod provided with a bend delimiting a first portion provided with fixing means 28 and a second part comprising the first and second portions.

  It should be noted that, in the context of the present description, rod means any element of generally elongated and thin shape such as a strip, so that it is not beyond the scope of the invention when the device is provided with an anti-slip part provided with an axial abutment which extends along the wall of the container and which has indifferently a cross section in round, parallelepipedal, oval, ..., and a rectilinear or curved shape .

  For example, the second portion is constituted by a shoulder extending transversely from the second portion.

  For example, the shoulder has a general parallelepiped shape.

  In an advantageous embodiment, the rod is provided at one of its ends with a ring adapted to be mounted around a neck of the container.

  In this embodiment, the inner diameter of the ring is preferably adapted to allow insertion of the ring around the neck with clearance, the outer diameter of the ring being substantially equal to the outer diameter of the product dispenser member. .

  In addition, preferably, the height of the ring is greater than or equal to the height of a space formed between the product dispensing member and the wall of the container, when said dispensing member is mounted on the neck in the absence of anti-slip device.

  According to yet another characteristic of the invention, the first rod portion advantageously forms an angle with the ring which corresponds to an angle of inclination of a shoulder of the container with respect to a geometric axis of said container.

  According to yet another characteristic of the invention, the shoulder extends from the stem in a median zone of the first portion.

  In an exemplary implementation of the invention, the device comprises a shoulder implanted substantially at two-thirds of the length of the first portion, considered from the bent portion, in order to allow the stopper to be inserted between two fingers. the user, for example the index and middle finger.

  According to another embodiment of the device according to the invention, it comprises two mutually opposite ends each provided with fixing means, the device being configured, when it is mounted on the container by the ends of the rod, in the form of a loop.

  In this embodiment, it comprises for example at each end a ring adapted to be mounted around a neck of the container.

  Preferably, the device comprises a band of elastically deformable material provided at each end of said ring, the loop being closed by folding the strip.

  The device according to the invention can be made in one piece by molding a plastic material. It can thus be achieved at low cost. In addition, the use of an elastically deformable plastic is advantageous insofar as, in this case, the ring can be pressed between the shoulder of the container and the dispensing member to ensure a seal. In addition, in this case, the rod can be deformed manually by pressing against the wall of the container for the extraction of the product.

  Finally, the device may comprise a rectangular section over at least part of its length.

  The invention also relates to a container for packaging and dispensing a product which comprises a body having a closed end and an open end forming a neck, and a product dispensing member mounted on the open end, characterized in that it further comprises an anti-slip device as defined above to improve the grip of the container.

  In one embodiment of this container, the neck is provided with an external thread on which is screwed the product dispenser member.

  This dispensing member has, for example, a generally conical shape and comprises a base provided with an internal thread intended to cooperate with the threading of the neck and a top provided with a manually breakable shutter element.

  Other objects, features and advantages of the invention will appear on reading the following description, given solely by way of nonlimiting example, and with reference to the appended drawings, in which: FIG. front view of a container for packaging and dispensing a product; FIG 2 is a profile view of the container of Figure 1; FIG. 3 is a perspective view of an anti-slip device according to a first embodiment of the invention, intended to be mounted on the container of FIG. 1; FIGS. 4, 5, 6 and 7 illustrate the different phases of mounting an anti-slip device on a container according to the invention; - Figure 8 is a diagram illustrating a mode of use of the container according to the invention; FIG. 9 illustrates a second embodiment of an anti-slip device according to the invention; and FIGS. 10, 11 and 12 illustrate the different phases of the assembly of the anti-slip device of FIG. 9.

  FIGS. 1 and 2 show a container for packaging and dispensing a product, designated by the general reference numeral 1 and represented in a supposedly vertical imaginary position. I1 has an axis of symmetry X-X '.

  For example, this container 1 is intended to contain an oxidant for reacting with an oxidation dye precursor to form a hair dye.

  In the embodiment shown in these figures, the container 1 is made in the form of a tube with deformable walls, which comprises a body 2 provided with a lower end 3 closed by pinching and heat sealing and an upper end 4 which has a neck 5 which coincides with the longitudinal axis XX 'of the body 2.

  As is known per se, the neck 5 is separated from the periphery of the container by an annular shoulder 6, generally frustoconical, which extends in slope of the neck 5 towards the peripheral wall of the body 2.

  Furthermore, the tube 1 is provided with a dispensing member 7 in the form of a generally conical tip mounted on the neck. It comprises a base 8 internally provided with a thread intended to cooperate with an external thread 9 formed in the neck 5, and an apex S closed by a breakable cap 10 with fins. The member 7 delimits internally a conduit allowing, after rupture of the breakable seal 10, to extract the product contained in the tube by pressure on the walls of the tube.

  As can be seen in particular in FIG. 2, due to the pinch closure of the lower end 3, the body 2 of the tube has strongly reciprocating mutually opposite anterior and posterior surfaces which delimit a relatively open angle α between them. As indicated above, such a tube is likely to slip when it is handled, in particular during the extraction of the product.

  Also, the tube 1 is completed by an anti-slip device.

  According to a first embodiment illustrated in FIG. 3, the anti-slip device 11 essentially consists of a rod 12 provided at one end with a ring 13 possibly interrupted over a portion of its circumference and which is intended to come position itself around the neck 5 of the tube. The internal diameter d1 of the ring 13 is slightly greater than the external diameter of the neck, to allow the insertion of the device 11 around it with clearance. The external diameter d2 of the ring 13 is, for its part, substantially equal to the outer diameter of the base 8 of the dispensing member 7. In addition, the height h of the ring 13 is less than the height h '(Figure 1) of a space delimited by the tip 7 and the shoulder 6 of the tube, when the tip is screwed fully on the neck.

  FIG. 3 also shows that the rod 12 has a bent portion 14. This bent portion 14 delimits a first straight rod portion 15 which extends from the ring 13 and which forms with the plane thereof an angle a 'which corresponds substantially to the slope of the shoulder 6 of the tube.

  The bent portion 14 also delimits a second rod portion 16 which forms, with the first portion 15, an angle α "which substantially corresponds to the angle α" 'formed between the shoulder 6 of the tube and an anterior or anterior wall of the tube 2 (Figure 2).

  The second shaft portion 16 extends rectilinearly.

  In the exemplary embodiment shown, the rod 11, including the first and second rod portions 15, 16, has a rectangular cross section. It has an inner surface 17, intended to be turned towards the tube 2 and an opposite surface 18.

  Between the elbow 14 and the free end 19 of the rod, the second rod portion 16 comprises a first rectilinear portion 21 intended to be applied, when the device is mounted on the container, substantially against the lateral or peripheral surface of the container and a second portion constituted by a shoulder 20 erected transversely from the first portion 21.

  As will be described in detail later, this shoulder 20 is intended to constitute a bearing surface for the hand of a user and is intended, for example, to be inserted between two fingers of the user, for example between forefinger and middle finger, to facilitate the gripping of the tube and avoid any risk of slipping by providing an axial stop.

  For example, the shoulder 20 extends along the entire width of the rod 11, at a height compatible with the user's morphology, and in a thickness sufficient to give it rigidity that allows it to perform its function, but also weak enough to fit between two fingers.

  Preferably, the device 11 is made in one piece, by molding a plastic material, preferably an elastically deformable plastic material.

  Thus, for example, the device 10 made of polyethylene, giving elasticity to the device 11. Also, thanks to this elasticity, and the height h of the ring relative to the height h '2890047 9 of the interstice between the tip and shoulder 6, the ring can be compressed after complete screwing of the dispensing member 8 to provide sufficient sealing.

  In addition, the rod 11, in particular due to its rectangular cross section, can be a support element against the wall of the tube that can be manipulated by the user to proceed with the extraction of the product.

  With reference to FIGS. 5 to 8, the use of the container which has just been described is as follows.

  As indicated above, the device 11 is mounted, by its ring, on the open end 4 of the tube. To do this, it is first necessary to unscrew the dispensing member 8 (Figure 4). The ring 13 is then inserted around the neck 5. In this position, represented in FIG. 5, the rod 11 is applied against the wall of the tube. In particular, the first shank portion 15 extends along the shoulder 6, while the second shank portion 16 extends along one of the anterior or posterior walls of the tube. It is then necessary to close the tube by screwing the dispensing member 8 on the neck (Figure 6). As explained above, after complete screwing of the tip, the ring provides a seal to the product. The lid 10 is then broken (FIG. 7).

  As shown in Figure 8, the plug of the tube 2 provided with the anti-sliding device 11 is then provided. Indeed, when the tube is grasped by inserting the shoulder 20 between two fingers, for example between the index finger and middle finger, it is possible to press on the tube without the latter being able to slide, even when the tube is seized with gloves contaminated with a slippery product.

  The extraction of the product can then be carried out by pressure on the walls of the tube, which is effected, on the anterior or posterior side, by means of the second rod portion 16.

  Of course, the invention is not limited to the embodiment described.

  Indeed, in the embodiment shown, the stop is made in the form of a shoulder extending about two-thirds of the second rod portion.

  It is also possible, alternatively, to provide several stops depending on the number of desired support points.

  Similarly, the shape of the stops can be modified without departing from the scope of the invention.

  In addition, it is also possible to provide a surface treatment of the rod, in particular the outer surface of the second rod portion 16 to further confer an anti-slip character to the rod.

  A second embodiment of an anti-slip device according to the invention will now be described with reference to FIGS. 9 to 12.

  Referring firstly to Figure 9, the device is in the form of a strip 22 of elastically deformable material provided, at each of its mutually opposite ends, two rings 23 and 24 of identical internal and external diameters to the diameters d1 and d2 of the ring described above with reference to FIG.

  For mounting this device on a container, it is necessary to fold the band on itself so as to superimpose the two rings 23 and 24. Thus, in this case, the height of each of the rings is such that the overall height of two stacked rings corresponds to the height h of the ring 13 of the embodiment described with reference to FIG.

  Referring to Figure 10, according to this embodiment, the strip 22 is mounted first by one of its rings 23 around the neck 5 of the container. It is then necessary to fold the band 22 to bring the other ring 24 around the neck 5 (Figure 11). The tube is then closed by screwing the dispensing member 8 onto the neck (FIG. 12). In this position, the rings contribute to the sealing of the container. The band 22 can be obtained, for example, by molding or by cutting a flexible thermoplastic material or a foam, for example a polyethylene foam, a cell foam. closed or not. It is then possible to fold the band against the container and, in particular, against the anterior or posterior wall of the tube.

  The strip thus mounted on the container is then in the form of a loop which also comprises, as in the embodiment described above a first portion 25 which is applied along the tube and a second portion 26 constituted by a part bent of the band and which constitutes a stop for the hand of the user.

  In use, the taking of the container can be ensured by inserting the hand or one or more fingers in the loop, the distribution of the product being ensured by applying a force on the tube through the first portion 25 of the loop .

  Note that in the various embodiments described, it is possible to permanently mount the anti-slip device on the tube or on the dispensing nozzle 8 so that the device remains integral with the container or the tip when the this is removed. In this case, the device can be connected to the tip or to the tube, respectively, by frangible means of inviolability.
