Description

The present invention relates to a device for packaging and distribution of a product, by means of a pump, as used in particular for the packaging and distribution of certain cosmetic products. Such cosmetic products include hair products, personal care products, care, make-up or protection of the skin against the harmful effects of solar radiation.

Products packaged in bottles fitted with a pump are in vogue currently, and their market continues to grow. This is particularly the case for personal hygiene or sun protection products.

One of the disadvantages of using these pump bottles is their meaning use. Typically, due to the presence of the dip tube, one of which free end is near the bottom of the container, the bottle must be used head up. This condition is imposed by the fact that the free end of the tube diver must always be immersed in the product to be dispensed.

Systems without dip tube have been proposed, intended to operate in upside down position. With such systems, the pump is primed at the first use in head-up position of the device.

There are also flexible bag type devices, equipped with a pump without air intake, and not using a dip tube. Although satisfactory to In many respects, such systems, however, require vacuum filling of the pocket, so as to remove any volume of air above the product. In moreover, this absence of air, in particular with certain products, is difficult to maintain for the entire duration of use of the device.

Systems have also been proposed, using a ball whose position allows in theory to use the device both upside down and upside down. The problem then arises when the device is used in a horizontal position, this which is relatively common for the distribution of products such as deodorants. In this position, the position of the ball oscillates between its position head-up operation, and its head-down operating position. It Often results in defusing the pump.

The document GM 77 07 773 describes a device equipped with a pump, and comprising an outer container and an inner container, formed of material elastically deformable, rubber type. The pump is connected to a dip tube. The elasticity of the material forming the pocket forces the latter to compress as the product is dispensed by means of the pump, so that, at the end, the pocket is substantially in contact with the dip tube and the pump.

The disadvantages of such a configuration are numerous. First, the pocket must be filled under pressure in order to overcome the elasticity of the constituent material. In addition, the pressure inside the pocket varies from between the first use and the last, which can cause problems from the standpoint of proper pump operation. Otherwise, due to the elasticity of the pocket, there is a great risk that the pocket will plate against the free end of the dip tube, and closes the inlet port. The risk is also great for that, depending on the thickness of the walls of the pocket, the free end of the dip tube pierces the pocket. Finally, the impermeability of elastomeric materials, and their compatibility with good number of products used in fields such as cosmetics, are more insufficient.

It is therefore one of the objects of the invention to provide a device for packaging and distribution, equipped with a pump, and able to operate, as long as possible, regardless of the position of the device, particularly in horizontal position.

It is another object of the invention to provide such a device which is capable of allow the container to be emptied as completely as possible.

It is yet another object of the invention to provide such a device which does not does not require vacuum filling of the flexible bag which contains the product.

It is another object of the invention to produce such a device, which is simple of use, reliable, and economical to carry out.

Still other objects will appear in the detailed description which follows.

According to the invention, and completely surprisingly, the applicant has discovered that all or part of these objects could be achieved by performing a such a device in the form of a container inside which is placed a pocket with flexible walls containing the product, said bag being connected to a pump without return air fitted with a dip tube, one free end of which is located substantially half the axial height of the pocket, means allowing an air inlet in the volume outside the pocket as the product is pumped inside the latter, the pressure inside the pocket, at least prior to the first use of the device, being less than or substantially equal to atmospheric pressure.

The terms "substantially equal", referring to pressure, reflect the fact that it there may be a slight increase in pressure inside the bag by compared to atmospheric pressure, due to factors external to the device itself even, such as an increase in temperature. The pressure comes back generally at atmospheric pressure when the external factor in question disappears. In document GM 77 07 773, the overpressure results from the configuration of the device itself, in this case, the elasticity of the pocket, which overpressure, by the very admission of the document, is maintained until the last use of the device.

In reality, according to the invention, the filling of the bag is preferably done at the atmospheric pressure, which atmospheric pressure, if we ignore pressure variations linked to the external factors mentioned above, and variations related to transient phenomena occurring over time necessary for the return of atmospheric pressure outside the pocket, is kept inside the pocket until the last use of the device.

The air intake outside the pocket helps maintain the volume surrounding the pocket substantially at atmospheric pressure, thus facilitating contraction adequate bag as the product is pumped.

By "substantially half the axial height of the pocket" means more close to the axial mid-height of the pocket than to either end of the latter. Preferably, however, the free end of the dip tube is as close as possible to the axial mid-height of the pocket. Of course, the height of the pocket to be taken into account in determining the mid-height, is the effective height of the pocket, i.e. the height capable of containing some cash. Likewise, the ends of the pocket designate the ends of the pocket corresponding to its effective height. So, in case the pocket extends over all or part of the height of the container neck, which is occupied by the pocket height means the height of the pocket under the neck of the container, the base of the neck corresponding substantially to a first end of the pocket, the bottom of the pocket corresponding to the other end.

A pump without return air means a pump which does not allow reentry of air inside the pocket containing the product, replacing the volume of product aspirated. The resulting reduction in pocket volume is compensated for on the other hand by an air inlet outside the pocket, i.e. in the volume between the outer container and the bag, until obtained of a pressure substantially equal to atmospheric pressure in said volume.

As the product is pumped inside the bag, this last contracts so that the volume of the pocket located above the free end of the dip tube is substantially equal to the volume of the pocket located below the free end of the dip tube. By "substantially equal" we hears a difference in volume, preferably less than or equal to 25%, and more preferably, less than or equal to 10%, and more preferably, less or equal to 5%.

This conservation or quasi-conservation of the identity of the volumes above and below the free end of the dip tube keeps the level of substantially constant product in the pocket as the product is pump. In this way, whatever the position of the device (head up, head bottom, angled, or horizontal), during the pumping of substantially all of the contents of the bag, the free end of the dip tube is immersed in the product. The pump cannot be primed.

In other words again, the free end of the dip tube, thus arranged at mid-height of the pocket, is always at the center of the "virtual sphere" described by the product surface when the device is moved in all directions possible around the point corresponding to said free end.

According to the invention, and unlike certain pocket systems without a dip tube, it is not necessary to fill the device under vacuum. Indeed, the presence of a air volume above liquid level does not affect proper operation of the device as long as the free end of the dip tube is submerged in the product. Preferably, however, during filling, arrangements will be made for have a filling level as high as possible, and in any case, above from the free end of the dip tube.

In practice, it appears that with the invention, even in its configuration the simpler, i.e. without the attachment zones to which reference will be made thereafter, more than 85% of the product can be pumped regardless of the position of the device during pumping (head up, head down, tilted or horizontal). At above 85% to 90%, may appear problems when pumping in horizontal position. For the last 5 to 7%, the head up or head up position bottom, depending on the configuration of the container and the pocket, may constitute a privileged position of pumping. Such performances are, for some applications, considered entirely satisfactory, to the point that this configuration simpler, because of its simplicity and low cost, may constitute a preferred embodiment of the invention.

The rate of refund, in any position of the device, can however be still improved by attaching the pocket to the interior wall of the container along at least one zone extending longitudinally to the X axis of the pocket. The, or areas of attachment allow better control of how the pocket will compress pumping thread, and facilitate the conservation of the identity or virtual identity of the volumes below and above the free end of the tube diver. In this way, it is possible to arrange so that, in practice, the volume difference below and above the free end of the tube diver does not exceed that generated by the differences in shape inherent in the presence of a possible neck and a flat bottom of the outer container.

Advantageously, the cross section of the pocket as well as the arrangement of the, or attachment zones are chosen so that, as the product is pumped inside the pocket, the cross section of this the latter decreases by remaining, over at least a portion of its axial height, containing the free end of the tube, substantially symmetrical about a plane means containing said free end and perpendicular to said axis X. Maintaining of this symmetry with respect to the free end of the dip tube, and which, from preferably extends over most of the axial height of the pocket, facilitates in to a large extent, the preservation over the pumping of identity or quasi-identity volume of the pocket above the free end of the dip tube, and below the free end.

According to a preferred embodiment, the cross section of the pocket thus that the arrangement of the, or fixing areas are chosen so that, as and as the product is pumped inside the bag, the section transverse of the latter decreases by retaining on at least said portion axial, a shape that is substantially symmetrical about an axis containing the tube diver. This arrangement makes it possible to reduce as much as possible the "dead volume" of product that will be difficult to pump. In addition, it facilitates the design of the device.

Advantageously, the pocket is able to pass from a first position in which it has a maximum cross section at a second position in which it has a minimum cross section, said pocket being in the second position, in the vicinity, or even in contact, of the dip tube along at least one longitudinal zone. Again, this provision contributes to reduce the dead volume mentioned above.

Preferably, the internal cross section of the outer container is shaped identical to the shape of the cross section of the pocket when the latter is in the first position. This arrangement optimizes the volume of product contained in the device, and to facilitate the realization of the device, especially when the latter is produced by coextrusion.

More preferably, the cross section of the pocket as well as the arrangement fixing zones are chosen so that the profile of the pocket portion extending between two consecutive fixing zones deforms so substantially symmetrical with respect to the mean plane passing through the two said areas. This arrangement facilitates complete emptying of the device, and contributes to facilitate maintaining the volume of product in the pocket at a constant level.

Preferably, said plane cuts substantially in the middle of the segment right connecting the dip tube to the point of said most cross section away from the dip tube when the pocket is in the first position. So in the second position, said portion which, in the first position is the most distant from the dip tube, is substantially in contact with the dip tube.

Preferably, the attachment zone (s) extend continuously over substantially the entire height of the pocket so that said axial portion roughly corresponds to the axial height of the pocket. This provision obviously helps to maintain the volume identity of the pocket below and above the free end of the dip tube, and to reduce maximum product level variations generated by pumping at inside the pocket.

The cross section of the pocket may be symmetrical around a axis. Preferably, it has, in the first position of the pocket, at least four sides, the pocket being attached to the container along N attachment areas longitudinal (N greater than or equal to 3) arranged on axes of symmetry of order N of said cross section.

According to a first preferred example, in the first position of the pocket, said cross section is square, a longitudinal fixing area extending in the middle of each face of the section. So we have four lines of fixing of the pocket on the internal surface of the external container.

According to a second preferred example, in the first position of the pocket, said cross section is hexagonal, a fixing zone longitudinal extending at an angle of two of said section. So we have three pocket attachment lines on the inner surface of the outer container.

Advantageously, the cross section of the pocket is substantially maximum at half its height, and gradually decreases towards each of its ends. The decrease is symmetrical on either side of the transverse plane pocket median. This arrangement is optimal for reducing the dead volume discussed above, and to allow operation in any position, also as long as possible.

Preferably, the air intake means outside the pocket are consisting of one or more orifices or slots made in the bottom of the device. Such orifices or slots may result from the use of first and second physico-chemically incompatible materials to form on the one hand the outer container, and secondly, the flexible pocket, and the realization of the device by coextrusion. Indeed, in this configuration, at the bottom of the device, the walls of the pocket oppose the welding of the edges of the outer container, thus generating in the bottom of the device, an air intake slot.

The fixing zone (s) can be ensured by means of a third material, in particular thermoplastic, physico-chemically compatible with said first and second materials. It may especially be an adhesive.

By way of examples, the first material may consist in particular of a polyethylene terephthalate, ABS, or styrene.

Also by way of examples, the second material can be made in particular polypropylene or polyethylene.

As examples, the third material can be made of a resin marketed by the company MITSUI ™, under the trade name ADMER ™ (grade SF 600, SE 800 or SF 620E) or a resin sold by ATO ™ under the trade name LOTADER ™ (grade TX8030 or HX8020).

The pump can be mounted on the device, in particular by crimping or screwing.

Preferably, the device is equipped with a dispensing head for actuation of the pump and distribution of the product via at least one orifice of distribution. The dispensing orifice can be formed in a nozzle, a grid, or in an element made of porous material, in particular a sintered material or a foam.

The device according to the invention is particularly suitable for packaging and the distribution of a cosmetic product, in particular a hygiene product body, a perfume, a makeup product, a hair product, a care product, or a product to protect against the harmful effects of the sun.

• les figures 1, 2, 3A-3D, 4 et 5 sont relatives à un premier mode de réalisation du dispositif selon l'invention; et
• les figures 6A-6C sont relatives à un second mode de réalisation du dispositif selon la présente invention.

The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:

• Figures 1, 2, 3A-3D, 4 and 5 relate to a first embodiment of the device according to the invention; and
• Figures 6A-6C relate to a second embodiment of the device according to the present invention.

The device 1 described with reference to Figures 1, 2, 3A-3D, 4 and 5 is shaped generally elongated along a longitudinal axis X. The device 1 comprises a outer container 2, rigid or semi-rigid, made of polyethylene terephthalate. The outer container 2 is of square cross section, with rounded corners. The outer section is maximum at the median transverse plane of the container 2 and gradually decreases towards its two ends, so that symmetrical with respect to said median transverse plane. At one of its ends, the container 2 ends with a flat bottom 3. At the other end, it ends with an open neck 4 inside which is mounted by snap-fitting or crimping a pump without air intake 5. The pump 5 is surmounted by a push button 6 for its actuation, and for the diffusion of the product via at least one orifice of outlet 7. A removable cover 8 covers the push button 7 in the storage or transport of the device.

Inside the rigid or semi-rigid outer container 2 is disposed a pocket for flexible walls 10, which in the maximum expansion position (as shown in Figures 2 and 3A is of cross section similar to the cross section inner of outer container 2. So in this filling position maximum the walls of the pocket 10 fit relatively perfectly the inner walls of container 2. The pocket 10 is the same height as the height of the outer container 2 and ends at one end with a closed bottom 11, and the other end by an open edge 12 held in the neck 4 of the container outside 2 by clamping between the latter and the pump body 5.

The bag 10 is made of a thermoplastic material, physico-chemically incompatible with the material forming the outer container 2. According to this example, a polyethylene bag is used.

The airless pump 5 is thus in communication with the flexible bag 10, which contains the product to be distributed. Product supply to the pump is done via a dip tube 13, the free end of which is substantially halfway up axial of pocket 10 (excluding collar).

As appears more clearly in Figure 3A, the pocket 10 is welded to the inner wall of outer container 2 via four weld lines 15, 16, 17, 18 arranged on axes of symmetry of order 4 of the square defined by the section of the pocket 10. Thus, the attachment zones each extend in the middle of one face of the square formed by the section of the outer container 2, and extend over the entire height (excluding neck) of the outer container 2.

Advantageously, the device according to this particular embodiment is produced by coextrusion, the coextruded parison comprising an outer layer continuous, intended to form the outer container 2, a continuous inner layer intended to form the pocket 10, and a discontinuous layer, between the internal layer and the outer layer, intended to form the four longitudinal fixing zones 15, 16, 17, 18.

The discontinuous layer is formed from a material compatible with both the material of the outer layer and with the material of the inner layer. AT by way of example, a resin sold by the company MITSUI ™ is used, under the trade name ADMER ™ (grade SF 600, SE 800 or SF 620E). As an example, a resin sold by the company is used. ATO ™ under the trade name LOTADER ™ (grade TX8030 or HX8020).

The material forming the discontinuous layer being compatible with the materials forming the inner and outer layers, the inner layer will stick to the outer layer via the four longitudinal strips 15, 16, 17, 18 formed by the discontinuous layer.

The parison thus formed is introduced into a mold with the shape and dimensions required for the device. When the mold closes, the flexible pocket goes close continuously, including at the bottom. However, at the junction area of the bottom, the edges of the flexible pocket will be interposed between the two edges of the outer container, and, due to the incompatibility of the materials forming the flexible bag and the outer container, preventing said edges from weld with each other, leaving in the bottom of the outer container after demoulding and removal of the pinching area of the mold, a slot 9, allowing air to be taken up inside the volume delimited between the flexible bag 10 and the outer container 2.

As it appears in Figure 2, the flexible bag 10 is filled with product, substantially to the neck 4 of the container 2, and in any case well above the free end 14 of the dip tube 13.

In use, by actuating the pump 5 via the push button 6, a dose of product is dispensed from the flexible pouch 10. In response to dispensing this dose, and due to the lack of air intake inside the pocket flexible, a depression is created inside the latter, which depression causes the walls of the pocket to collapse towards the tube diver. The collapse of the walls of the flexible bag 10 is done so organized, due to the presence of the weld zones 15, 16, 17, 18, via which the pocket 10 is fixed to the outer container 2.

Figures 3A-3D illustrate the different profiles occupied by the flexible bag 10 between the maximum filling position (Figure 3A) and the emptying position maximum (Figure 3D).

In FIG. 3A, the walls of the flexible bag 10 stick perfectly to the walls the inner container 2.

In FIG. 3B, after several pumpings, the corners of the pocket have started their movement converging towards the X axis of the device, and this over the entire pocket height. Thus, the pocket retains a symmetrical section on the one hand with respect to its mean transverse plane, and on the other hand all around the X axis containing the dip tube 13. This results in a reduction in the cross-section of the pocket, uniform over its entire height, which allows to maintain a quasi-identity volume above and below the free end of the dip tube, and to maintain the product inside the flexible pouch 10, at a level substantially constant.

In FIG. 3C, the converging movement of the four corners of the pocket 10 in direction of the dip tube continues over the pumping, until reversal complete pocket profile between two consecutive fixing zones 15, 16, 17, 18 (Figure 3D). As it appears in Figures 3A-3D, the profile inversion takes place symmetrically with respect to the mean plane passing through two consecutive weld zones.

In the position of Figure 3D, the four corners of the pocket are in contact with the dip tube along four longitudinal zones 19, 20, 21, 22, the pocket being also kept attached to the outer container in the middle of each of its four sides. As it appears in Figure 3D, in this position, the volume of the bag is now substantially zero, the passage of the maximum volume (figure 3A) at the minimum volume (FIG. 3D) having been carried out while permanently keeping a symmetry of the pocket on the one hand with respect to the average transverse plane of the pocket, and on the other hand, the cross section of the pocket around the X axis of the device. It follows that by going from the configuration of FIG. 3A to the configuration of FIG. 3D, in spite of the reduction in volume of the pocket 10, the level of product inside it did not move so significant. The immersion of the free end 14 of the dip tube 13 inside the product is extended to the maximum due to the decreasing pocket section gradually from its extremities towards its median transverse plane in which is located the free end of the dip tube 13.

At the end of use of the device, when the vacuum created by the pump becomes insufficient to further compress the bag, the level of product in the pocket drops, until it passes below the free end of the dip tube. AT at this point, the product can no longer be pumped. This residual volume is located essentially around the dip tube, and in the vicinity of the junction zones. Before reaching the stage where the product can no longer be pumped, it may be necessary to goes through a phase in which pumping can only be done in one privileged position of the device (either head up or head down). In the practical, it should be arranged so that these phases during which the pumping can no longer be done, or only unidirectionally, either as short as possible.

Figures 4 and 5 show a longitudinal sectional view of the device for a intermediate compression position of the pocket as shown in the view in cross section of Figure 3C. As it appears in these figures, the product level inside the bag is identical to the product level before the first use of the device (Figure 2). In both head-up positions and upside down, the free end 14 of the dip tube is largely immersed in the product. The same applies when the device is used in a horizontal position.

The embodiment of Figures 6A-6C differs from the embodiment previous in that the cross sections of the outer container 2 and the pocket 10 are hexagonal instead of square. The fixing zones 15, 16, 17 are located on the axes of symmetry of order 3, that is to say at the level of a angle on two.

In the same way as for the previous embodiment, over the pumping, the profile of the pocket portions located between two attachment zones is reversed, substantially symmetrical to the plane containing the two consecutive fixing zones, until it comes into contact with the dip tube 13 in three longitudinal zones 19, 20, 21. In this position, the volume of the flexible bag is minimal. How this mode works implementation is also identical in all respects to the operation of the previous achievement.

In the foregoing detailed description, reference has been made to modes of preferred embodiments of the invention. Obviously there may be variations made without departing from the spirit of the invention as claimed below.
