Description

The present invention relates to a device for conditioning and

  delivering a liquid contained in a container.

  It relates more particularly, but not exclusively, to the production of a bottle intended to contain a cosmetic or pharmaceutical product, having a viscosity such that the product can be delivered by deforming the walls of the bottle, and more particularly by exerting a compression on the walls of the bottle.

  Such liquid product dispensers are known, comprising a bottle made of a sufficiently elastic material to be able to return to its original shape after deformation.

  The bottle has an opening, through which the product is introduced, and a liquid product taking tube, the tube being introduced into the bottle and held by one of its ends in the vicinity of the opening of the bottle.

  The bottle also has a sealing closure of the opening, so that the liquid does not spill when the bottle is, for example, in the supine position.

  Such devices have the following disadvantages in particular: When deforming the bottle by manual support on its side wall, the upper part of the bottle (which is located near its opening) also deforms, and the bottle hardly resumes its original shape ; The resumption of shape of the bottle is slow, which implies a waiting time for the user between two successive uses.

  The present invention aims to overcome these disadvantages.

  It relates to a device for packaging and dispensing a liquid product, comprising a container deformable by compression, or manual support, on its side walls, in which the liquid to be delivered is stored. The container is closed by a dispensing head of the liquid product which is traversed by an outlet of the product. The device also comprises a liquid-collecting tube, one end of which is fixed in the vicinity of the outlet orifice of the liquid, the tube being of such length that its other end is in the vicinity of the bottom of the container to ensure the sampling of the liquid. liquid. According to the invention, the wall of the container has cavities which partially delimit the contour of the dispensing head, to absorb the deformation stresses when the wall of the container is compressed, in order to avoid deformation of the dispensing head. In addition, at least one air circulation passage is formed in the vicinity of the dispensing head to ensure air entry into the container after distribution of the liquid, so as to allow the container to resume its original shape by replacement, or compensation, by volume of the dose of liquid delivered.

  In order to best preserve the dispensing head during the deformation of the bottle, it is preferable that said cavities are made such that they extend radially at least partially peripheral under the level of the dispensing head.

  Thus achieved, the container returns to its original shape faster than the known bottles, and the dispensing head does not deform.

  According to one embodiment, the container comprises at least two communicating compartments, interconnected by two deformable zones which allow the two compartments to be brought together by pressing against their external walls. A channel is advantageously provided between the two compartments forming a passage for the liquid contained in the container.

  Advantageously, the deformable zones consist of grooves which are arranged in an axial direction between two compartments, so as to promote the deformation of the side walls of the compartments.

  According to a second embodiment, several air inlet passages in the container are formed in the dispensing head. This makes it possible to increase the flow rate of air entering the container after delivery of liquid product, and thus to accelerate the recovery. of initial shape of the container.

  The passages are preferentially distributed uniformly around the end of the gripping tube, to promote a uniform distribution of the air entering the container and thus allow a recovery of uniform initial shape of the container.

  According to an alternative embodiment, the container comprises a liquid filling opening to be dispensed, and the dispensing head is made in the form of a plug for closing the filling opening.

  According to an advantageous embodiment of the device according to the invention, the cap comprises a base to be fixed on the opening of the container, the base having the liquid outlet orifice, and a closing cap of the orifice which is connected to the base by a hinge.

  The base preferably comprises a receiving housing of the end of the gripping tube, the housing being traversed by at least one air passage.

  According to an alternative embodiment of the device according to the invention, provision is made to produce the integral head of the container.

  Other features and advantages of the invention will become apparent on reading the description which follows, with particular reference to the appended figures in which: FIG. 1 shows a device according to a first embodiment according to the invention for the purpose of next to ; Figure 2 illustrates the device of Figure 1 in front view; - Figure 3 shows the device of Figures 1 and 2 in profile view; FIG. 4 represents the device of FIG. 4 equipped with a closing cap in the open position; Figure 5 is a longitudinal sectional view of the device shown in Figure 1; Figure 6 shows the shape taken by the device of the preceding figures when a pressure is exerted on its side wall, in side view (high figure) and cross-sectional view (low figure); Figure 7 is a partial sectional view of the device shown in Figure 8; FIG. 8 illustrates a dispensing head of the device according to the invention, for longitudinal sectional view, when the liquid is expelled from the container that comprises the device according to the invention, as well as the movements of air and liquid contained in the inside the container (movements symbolized by arrows); and Figure 9 illustrates the dispensing head shown in Figure 8, in longitudinal sectional view, when the container returns to its shape after being deformed by a user, as well as the movements of air entering the container (movements symbolized by arrows).

  In the context of the exemplary embodiment of the device according to the invention shown in FIGS. 1 to 9, the device is intended for the packaging of cosmetic or pharmaceutical liquid products.

  As can be seen in particular in Figures 1 and 2, the device comprises a container 1 which is made of an elastically deformable material with shape memory.

  In this way, the container can be deformed by compression of its side wall, and it can return to its original shape by elastic return.

  Said liquid to be delivered is stored in the container 1. The liquid is introduced through an opening 10 formed in the container (Figure 5).

  The container 1 comprises at least two communicating compartments 11 and 12, interconnected by two deformable zones 13 and 14 (FIG. 6) which allow the two compartments 11 and 12 to be brought together by pressing on their external walls, a channel 15 being provided between the two compartments 11 and 12 forming a passage for the liquid contained in the container 1.

  The two deformable zones 13 and 14 each consist of grooves which are each formed between two compartments 11 and 12 to promote the deformation of the side walls of the compartments.

  The grooves are formed directly during molding, by means of the shape of the mold.

  The container 1 is closed by a head 2 for dispensing the liquid product.

  More precisely, the dispensing head 2 is made in the form of a plug 7 for closing the filling opening 10.

  However, it should be understood that the invention is not limited to an embodiment in two separate parts of the container and the cap. According to an alternative embodiment of the device according to the invention, the dispensing head 2 could be made integral with the container 1.

  According to the presently described and illustrated embodiment, the plug 7 comprises a base 71 to be fixed on the opening of the container and a cap 72 mounted hinged between open position and a closed position on the base 71.

  To do this, the cap 72 is connected to the base 71 by a hinge.

  The base 71 has two cylindrical inner skirts 73 and 74 (Figures 7 is and 8), having different diameters and being centered around the axis of the base.

  The two skirts 73 and 74 maintain the base on the container by positioning on either side of a neck of the container, said neck defining the opening 10 of the container 1.

  To maintain the base 71 in position, the end of the inner skirt 73 is in the form of a hook 75 engaging under a bead 16 formed protruding from the neck 10 of the container (Figure 9).

  The base 71 is traversed by an orifice 3 for the liquid product (FIGS. 4, 5, 8 and 9).

  Incidentally, the base 71 has axial grooves 17 which are positioned facing the grooves 13 and 14 of the container when the cap 7 is fixed on the container 1. This gives the device a more aesthetic appearance (Figure 2).

  Furthermore, the base has a recess 18, formed radially opposite the hinge which connects it to the cap, and in the vicinity of the junction 30 between the base and the cap, to allow a user to open easily. the cap by positioning his thumb, for example, in the recess 18, and exerting a thrust towards the cap to tilt it to the open position.

  The device also comprises a tube 4 for taking liquid contained in the container 1.

  One 41 of the ends of the gripping tube 4 is fixed in the vicinity of the outlet orifice 3 of the dispensing head 2. To this end, the dispensing head 2 comprises an internal annular skirt 21 whose axis is confused with that of the orifice 3 so that the orifice is facing the end of the tube 4, to promote the evacuation of the liquid taken from the container 1 (Figures 5, 8 and 9).

  The tube 4 has a length such that its end 42, opposite the end 41, is in the vicinity of the bottom of the container to ensure the removal of the liquid (Figure 5).

  According to the invention, and as illustrated in Figures 1 to 6, the container wall has cavities 5 which partially define the contour of the dispensing head 2, to prevent deformation of the latter when the container is deformed by pressure on wall and eliminate the risk of malfunction.

  As can be seen in particular in Figures 1, 2 and 6, the cavities 5 extend radially at least partially peripheral under the level of the dispensing head (2).

  Indeed, as shown more particularly in Figure 6, when a pressure is exerted on the side wall of the container (pressure symbolized by the arrows P), the base of the dispensing head 2 is not deformed.

  It will be understood that the base of the dispensing head is the portion of the device that defines the boundary between the dispensing head and the container. In the context of the embodiment which is presently described and illustrated, the base of the dispensing head corresponds to the plane passing through the receptacle and the cavities 5.

  Indeed, the cavities 5 isolate the dispensing head 2 from the rest of the body of the container 1, so that when the container 1 is deformed by pressure on its side wall, the cavities 5 absorb the deformation stresses.

  The dispensing head 2 thus undergoes no deformation. 25

  The base 71 comprises a receiving housing of the end of said socket tube 4, said housing being traversed by at least one air passage.

  As shown in FIG. 7, three passages 60, 61 and 62 are provided in the dispensing head 2. The passages 60, 61 and 62 allow air to circulate between the inside of the container and the outside of the container.

  The passages 60, 61 and 62 ensure in particular an air inlet into the container after distribution of the liquid so as to allow the container to resume its original shape by replacement, or compensation in volume of the dose of liquid that has been delivered (see air circulation symbolized by arrows in Figure 9).

  The passages 60, 61 and 62 also allow the exit of the air contained in the container (Figure 8), which promotes the deformation of the container.

  The passages 60, 61 and 62 are uniformly distributed around the end of the gripping tube 4.

  In this way, the air entering the container is distributed uniformly, which allows a uniform initial recovery of the container 1.

  Thus realized, the device according to the invention has the following advantages: It is easily deformed, without having to apply a large force to compress the side wall of the container; It resumes easily and quickly its original shape after deformation, so that a user can spray two doses of liquid without having to wait excessively between two sprays as the container returns to its original shape; It is of simple design, and cheap, since it requires no delivery pump, the pumps commonly constituting the most expensive elements in the delivery devices.
