Abstract

The bottle (3) has an intermediate piece (25) mounted inside a body of the bottle and comprising a downstream opening connected to a dip tube (32) belonging to the bottle, where the tube is axially extended in the body towards upstream up to bottom (6) of the body. The intermediate piece has sealed connection units cooperating with a product pumping device (4) to evacuate a liquid or pasty product in the bottle through the dip tube by pumping. The intermediate piece is integrated to the body and mounted in a sealed manner against an inner face of the body. An independent claim is also included for a liquid or pasty product packaging and distributing device comprising a pumping device including a base provided with reversible assembling units fixed on a bottle.

Description

The present invention relates to a bottle for containing a liquid or pasty product and comprising a dip tube, and a device for packaging and dispensing a liquid or pasty product comprising on the one hand such a bottle and on the other hand a pumping device, devoid of dip tube, removably mounted and sealed on such a bottle.

The invention also relates to a kit comprising a plurality of such bottles and a single pumping device without a dip tube.

Methods for packaging and dispensing liquid or pasty products, such as gels or creams, used in the field of hygiene, pharmaceuticals or cosmetics for example, are already known.

These packaging and dispensing devices typically comprise a bottle, containing the product, and a pump mounted on the bottle and allowing the dispensing of the product. The pump is provided with a dip tube which extends inside the bottle, substantially to the bottom of it.

According to a first known embodiment, the pump is mounted on the bottle irremovably. So we have a disposable device, which has the disadvantage of being expensive and generate a large amount of waste.

According to a second known embodiment, the pump is mounted on the bottle removably, typically by screwing on the neck of the bottle. It is therefore possible, when the bottle is empty, to unscrew the pump and screw it on a new bottle, full. As a result, the quantity of waste is less, and the overall cost for the user is reduced because the pump is the most expensive member of the packaging and dispensing device.

However, this second embodiment has the following disadvantage: when the pump is removed from the empty bottle to be placed on the full bottle, the plunger tube is found in the open air. However, this tube is covered and at least partially filled with product. It follows that we can not guarantee the perfect asepsis of this type of packaging and dispensing devices, which can be unacceptable in some applications, pharmacy for example. Indeed, when the tube is immersed in the new bottle, the product contained therein may be contaminated. Moreover, it is generally unpleasant for the user to manipulate the covered tube of product, especially if this product is pasty, when transferring the pump from an empty bottle to a full bottle.

Other packaging and distribution devices are proposed by the documents EP 0 240 817 , FR 2,593,147 and LU 88,593 .

The present invention aims to overcome the disadvantages mentioned above.

• un corps comportant un fond à son extrémité amont et une ouverture à son extrémité aval, et muni de moyens d'assemblage réversible d'un dispositif de pompage du produit ;
• un élément de fermeture obturant l'ouverture aval du corps avant la première utilisation du flacon, et pouvant être séparé du corps ;

et, en outre, une pièce intermédiaire montée à l'intérieur du corps, comportant une ouverture aval reliée à un tube plongeur appartenant au flacon et s'étendant sensiblement axialement dans le corps vers l'amont sensiblement jusqu'au fond, ladite pièce intermédiaire étant pourvue de moyens de raccordement étanche destinés à coopérer avec le dispositif de pompage, de façon à permettre l'évacuation du produit contenu dans le flacon par le tube plongeur, par pompage, ladite pièce intermédiaire étant solidaire du corps du flacon et montée de façon étanche contre la face intérieure dudit corps.For this purpose, and according to a first aspect, the invention relates to a bottle intended to contain a liquid or pasty product, said bottle having an axis and comprising:

• a body having a bottom at its upstream end and an opening at its downstream end, and provided with reversible assembly means of a device for pumping the product;
• a closure member closing the downstream opening of the body prior to the first use of the vial, and being separable from the body;

and, in addition, an intermediate piece mounted inside the body, having a downstream opening connected to a dip tube belonging to the bottle and extending substantially axially in the body upstream substantially to the bottom, said intermediate piece being provided with sealing connection means intended to cooperate with the pumping device, so as to allow the product contained in the bottle to be discharged through the dip tube, by pumping, said intermediate piece being integral with the body of the bottle and mounted so as to sealed against the inner face of said body.

The terms "upstream" and "downstream" are defined with respect to the direction of flow of the liquid towards the outside of the vial. "Waterproof" means a seal to the liquid contained in the bottle.

Thus, the invention proposes a bottle comprising an integrated dip tube, which can be associated with a pumping device without a dip tube. By "integrated", it should be understood that the dip tube belongs to the bottle (and not to the pumping device). According to a first embodiment, the dip tube is made in one piece with the intermediate piece; according to a second embodiment, this dip tube is attached to the intermediate piece.

In practice, the bottle is initially closed (by the closure element) and the product can therefore neither leak nor be contaminated by an external element. At the moment of the first use, the user separates the closure element from the bottle, thus releasing the downstream opening of the body, then position the pumping device. This pumping device may not include a dip tube, since this tube is already provided in the bottle and that means for sealing connection between the bottle and the pumping device are provided. Therefore, when the pumping device is removed from an empty bottle to be placed on a full bottle, there is no long tube covered with product to move from one vial to another.

In addition, thanks to the invention, it is possible to market a kit comprising a single pumping device for several bottles, and thus to reduce the price to pay for a user for the same amount of product.

It should be noted that the intermediate piece is fixed relative to the body, and therefore it can not be extracted from the body. This is advantageous because it can thus ensure product hygiene and user safety.

It can further be provided that the intermediate piece does not protrude beyond the downstream end of the body, so that a user has no access to this room.

For example, the body comprises a substantially cylindrical portion and a neck of smaller diameter which is connected to this substantially cylindrical portion by a generally transverse wall forming a shoulder. The intermediate piece can then be mounted in abutment against this shoulder, upstream thereof.

The body is for example made from two separate parts, made by injection molding and assembled after mounting the intermediate piece in one of them.

According to one possible embodiment, the intermediate piece comprises an axial housing open at its two ends and connecting the downstream opening of the intermediate piece and the dip tube, said housing being intended to receive with sealing part of the pumping device.

For example, the intermediate piece comprises a transverse wall in which is formed the downstream opening, a skirt projecting from the transverse wall upstream, a generally tubular portion projecting from the transverse wall upstream, around the downstream opening, and whose inner zone forms the receiving housing of a portion of the pumping device, the upstream opening of said generally tubular portion being directly connected to the downstream opening of the plunger tube.

• une première partie cylindrique et une deuxième partie cylindrique de plus grand diamètre, un épaulement étant ainsi défini entre lesdites deux parties et formant une surface d'étanchéité destinée à être en contact avec une surface correspondante du dispositif de pompage ;
• une partie s'évasant vers l'amont, formant une zone d'introduction du dispositif de pompage dans le logement.

The generally tubular portion may comprise, from upstream to downstream:

• a first cylindrical portion and a second cylindrical portion of larger diameter, a shoulder being thus defined between said two portions and forming a sealing surface to be in contact with a corresponding surface of the pumping device;
• a part flaring upstream, forming an introduction zone of the pumping device in the housing.

Advantageously, the intermediate piece is snapped inside the body. In this way, a good axial resistance is obtained in both directions, and during the installation of the pumping device, it is not possible to separate the intermediate piece from the body and push it towards the bottom.

The body comprises for example a substantially cylindrical main part, open at its downstream end, and a cap mounted on the main part of the opening side, with sealing, the cap being open at its two axial ends and the intermediate piece being mounted inside the cap.

According to a second aspect, the invention relates to a device for packaging and dispensing a liquid or pasty product comprising a bottle as defined above and a pumping device mounted on the bottle removably and with sealing, the pumping device. being devoid of dip tube.

• une base munie de moyens d'assemblage réversible sur le flacon ;
• une tête comportant un conduit débouchant par une extrémité à l'extérieur de la tête, montée mobile en translation axiale par rapport à la base entre une position haute et une position enfoncée, sous l'action d'appui d'un utilisateur, pour délivrer par le conduit une dose de produit contenu dans le flacon ;
• un embout fixé dans la base et faisant saillie de celle-ci vers l'amont, l'embout comportant un canal axial ouvert à ses deux extrémités et en communication, en aval, avec le conduit ménagé dans la tête ;

l'embout étant dépourvu de tube plongeur et comprenant des moyens de raccordement étanche avec le flacon, permettant, en position assemblée du dispositif de pompage et du flacon, une mise en communication entre le canal axial de l'embout et le tube plongeur intégré au flacon.According to one possible embodiment, in this packaging and dispensing device, the pumping device has an axis and comprises:

• a base provided with reversible assembly means on the bottle;
• a head comprising a duct opening at one end to the outside of the head, mounted movably in axial translation relative to the base between a high position and a depressed position, under the action of support of a user, to deliver by the conduit a dose of product contained in the bottle;
• a nozzle fixed in the base and projecting from it upstream, the nozzle having an axial channel open at both ends and in communication, downstream, with the conduit formed in the head;

the nozzle being devoid of a dip tube and comprising means for sealing connection with the bottle, allowing, in position assembly of the pumping device and the bottle, placing in communication between the axial channel of the nozzle and the plunger integrated in the bottle.

Again, the term "integrated" does not mean that the dip tube is formed in one piece with the bottle. Indeed, it can be provided, alternatively, that the dip tube is a separate piece, attached to the bottle. The essential point is that this dip tube belongs to the bottle and not to the pumping device.

• une première partie sensiblement cylindrique et une deuxième partie cylindrique de plus grand diamètre, un épaulement étant ainsi défini entre lesdites deux parties et formant une surface d'étanchéité destinée à être en contact avec une surface correspondante du flacon ;
• une partie s'évasant vers l'amont, destinée à être introduite dans un logement de forme complémentaire ménagé dans le flacon.

The tip may comprise, from upstream to downstream:

• a first substantially cylindrical portion and a second cylindrical portion of larger diameter, a shoulder being thus defined between said two portions and forming a sealing surface for contact with a corresponding surface of the vial;
• a part flaring upstream, intended to be introduced into a housing of complementary shape formed in the bottle.

For example, the end portion of the tip has an outer face converging upstream, and has a radial projection intended to cooperate sealingly with a wall of the bottle. The tip thus has a tapered upstream end portion that facilitates its introduction into the bottle and provides a certain flexibility. This gives a spring effect which, in combination with the presence of the radial projection, provides a very good sealing contact with the housing of the bottle.

Finally, according to a third aspect, the invention provides a kit comprising a plurality of bottles as previously described, each bottle being filled with a liquid or pasty product and closed by a closure element, and a single pumping device, disjointed vials (that is to say assembled to none of the bottles), the pumping device being devoid of dip tube.

The pumping device in question may have the aforementioned characteristics.

Such a kit can be marketed at a very attractive price for the user, since it comprises only one pumping device for several bottles, which constitute refills.

The packaging and dispensing device 1 according to the invention has an axis 2 and comprises a bottle 3 and a pumping device 4.

Firstly, bottle 3 is described with reference to figures 1 and 2 .

The bottle 3 comprises a substantially cylindrical main part 5 provided with a bottom 6 at its upstream end, and an opening 7 at its downstream end. The inner face 8 of the main part 5 is cylindrical over the entire height, while the outer face 9 has a downstream end part also cylindrical but smaller diameter. The main part 5 thus comprises a thinned downstream edge 10 defining a crown shoulder 11 orthogonal to the axis 2. The downstream edge 10 comprises an annular bead 12 projecting radially from the outer face 9.

• vers l'aval, un col 16 entourant l'orifice central 15, le col 16 étant pourvu d'un filetage extérieur 17 et d'un retour 18 annulaire intérieur définissant une ouverture aval 19 ;
• vers l'amont, une jupe extérieure 20 périphérique pourvue d'une gorge intérieure 21 et une jupe intérieure 22, de plus grande longueur axiale que la jupe extérieure 20.

The bottle 3 also comprises a cap 13 comprising a transverse wall 14 provided with a central orifice 15. From the transverse wall 14 protrude:

• downstream, a neck 16 surrounding the central orifice 15, the neck 16 being provided with an external thread 17 and an inner annular return 18 defining a downstream opening 19;
• upstream, a peripheral outer skirt 20 provided with an inner groove 21 and an inner skirt 22, of greater axial length than the outer skirt 20.

The cap 13 is intended to be snapped, preferably irremovably, on the main part 5, thus forming the body of the bottle 3. In mounted position ( figure 2 ), the downstream edge 10 of the main part 5 is sandwiched between the outer skirt 20 and the inner skirt 22, the bead 12 being housed in the groove 21 and the upstream end of the outer skirt 20 abuts against the shoulder in crown 11. The outer face of the inner skirt 22 is in sealing contact with the inner face 8 of the main part 5, and the outer face of the outer skirt 20 is located in the extension of the outer face 9 of the main part. 5 (in his part of greater thickness), so that the body of the bottle 3 has a continuous outer face, without recess.

The downstream opening of the body is closed, before the first use, by a closure element. This closure element may be a screw cap (optionally provided with a tamper evidence such as a ring) or a peelable seal or a breakable appendage. In the embodiment shown, there is a breakable appendage 23 made in one piece with the cap 13 and connected thereto, at the downstream opening 19, by a junction zone 24 of lower resistance.

Finally, the bottle 3 comprises an intermediate piece 25. This intermediate piece 25 has a transverse wall 26 provided with a central opening 27 and which project, upstream, on the one hand, at its periphery, a skirt 28 and secondly, around the central opening 27, a generally tubular portion 29 whose inner region forms a housing 30 open at its two axial ends.

• une tige creuse 31 de petit diamètre, et sur laquelle est emmanché un tube plongeur 32 s'étendant sensiblement axialement dans le corps, vers l'amont, sensiblement jusqu'au fond 6. En variante, le tube plongeur 32 et la pièce intermédiaire 25 pourraient constituer une seule pièce monobloc ;
• une première partie cylindrique 33 de plus grand diamètre que la tige creuse 31, définissant une paroi radiale 34 contre laquelle le tube plongeur 32 vient en butée ;
• une deuxième partie cylindrique 35 de plus grand diamètre que la première partie cylindrique 33, un épaulement 36 étant ainsi défini entre lesdites deux parties cylindriques 33, 35 ;
• et une partie globalement tronconique 37 s'évasant vers l'amont.

The generally tubular portion 29 comprises, from upstream to downstream:

• a hollow rod 31 of small diameter, and on which is fitted a dip tube 32 extending substantially axially in the body, upstream, substantially to the bottom 6. Alternatively, the dip tube 32 and the intermediate piece 25 could be a single piece;
• a first cylindrical portion 33 of larger diameter than the hollow rod 31, defining a radial wall 34 against which the plunger tube 32 abuts;
• a second cylindrical portion 35 of larger diameter than the first cylindrical portion 33, a shoulder 36 being thus defined between said two cylindrical portions 33, 35;
• and a generally frustoconical portion 37 flaring upstream.

The intermediate piece 25 is snapped into the cap 13, reciprocal latching means (not shown) being provided for this purpose. In the mounted position of the intermediate piece 25 in the cap 13, the transverse wall 26 abuts against the transverse wall 14 of the cap 13, and the skirt 28 is in sealed contact with the inner skirt 22 of the cap 13.

The main part 5, the cap 13 and the intermediate part 25 are for example made by molding a plastic material such as polypropylene.

The pumping device 4 is now described with reference to FIG. figure 3 .

The pumping device 4 comprises first of all a base 38 having an internal thread 39 intended to cooperate with the external thread 17 of the neck 16 of the cap 13.

The pumping device 4 also comprises a head 40 comprising a first duct 41, oblique, opening at one end outside the head 40 and at another end in a second duct 42, axial, provided with radial orifices 43. The head 40 is movably mounted in axial translation relative to the base 38 between a high position and a depressed position, under the action of a user, to deliver through the orifices 43 and the conduits 42, 41 a dose of product contained in the bottle 3. The head 40 is further biased towards its upper position by a spring 44.

Finally, the pumping device 4 comprises a tip 45 fixed in the base 38 and projecting from it upstream, beyond the base 38. The tip 45 comprises an axial channel 46 open at both ends , able to communicate with the second duct 42, via the radial orifices 43, when the head is in the depressed position.

• une première partie sensiblement cylindrique 47 et une deuxième partie cylindrique 48 de plus grand diamètre, un épaulement 49 étant ainsi défini entre lesdites deux parties cylindriques 47, 48 ;
• une partie globalement tronconique 50, s'évasant vers l'amont.

The end piece 45 is intended to be placed in the housing 30 formed in the intermediate part 25, and therefore has an outer shape corresponding to the inner shape of this housing 30. Thus, the endpiece 45 comprises, from upstream to 'downstream :

• a first substantially cylindrical portion 47 and a second cylindrical portion 48 of larger diameter, a shoulder 49 being thus defined between said two cylindrical portions 47, 48;
• a generally frustoconical part 50, flaring upstream.

The end portion of the tip 45, at the first substantially cylindrical portion 47, has an outwardly converging outer face forming a ramp 51, and has a radial projection 52.

It should be noted that, in an essential manner to the invention, the pumping device 4 does not include a dip tube, since it is intended to be assembled, removably and with sealing, to the bottle 3 which already comprises a tube diver 32.

The method of assembly of the various constituent parts of the packaging and dispensing device 1 according to the invention is now described.

Vial 3 is obtained as follows. In a first step, the intermediate piece 25 (provided with the single-piece or insert plunger tube 32) and the cap 13 (provided with its closure member) are assembled. Then we just snap this set on the main part 5 previously filled with the desired product. It is in this form that the bottle 3 is marketed. It is perfectly waterproof and is a refill (atmospheric).

When a user wishes to obtain a certain quantity of the product contained in the bottle 3, he must first set up the pumping device 4 on the bottle 3.

At first, the user releases the downstream opening 19 of the bottle 3 by removing the closure element (here by detaching the appendage 23, according to the zone of least resistance 24). Then, it can screw the pumping device 4 onto the bottle 3 ( figure 3 ).

During the introduction of the pumping device 4, the tip 45 passes through the opening 19 and then is positioned in the housing 30. The generally frustoconical portion 37 of the intermediate piece 25 forms a facilitating and guiding the introduction area of the pumping device 4, as well as the ramps 51. As indicated above, the latching means between the intermediate part 25 and the cap 13 are arranged to prevent the screwing of the pumping device 4 from pushing the separation of the intermediate part 25 and the cap 13.

The figure 4 shows the packaging and distribution device 1 ready to use, the pumping device 4 being screwed onto the bottle 3. In this position, the tip 45 matches the shape of the housing 30, the end of the tip 45 being in abutment with the bottom of the intermediate piece 25, just downstream of the hollow rod 31, the radial projection 52 being in contact with the inner face of the first cylindrical portion 33 of the intermediate piece 25. In addition, the shoulder 49 of the nozzle 45 is in contact with the shoulder 36 of the intermediate piece, sealingly.

Thanks to the invention, there are means for sealing connection between the pumping device 4 and the bottle 3, that is to say with the dip tube 32, which make it possible to initiate the suction of the product by pressing on the head 40. It should be noted that the packaging and dispensing device 1 according to the invention does not require a seal for this purpose.

Thus, the invention provides a decisive improvement to the prior art, providing a device for packaging and dispensing a product which, with a simple structure, can significantly reduce the costs for the user. Indeed, it is possible to market a kit comprising several refill bottles with integrated dip tube (for example 10) for a single pumping device. In addition, this cost reduction is accompanied by a significant improvement in terms of asepsis and ergonomics for the user, who is no longer at risk of depositing the product in various locations, and unintentionally, during unscrewing. and screwing the pumping device back onto a full flask.

It goes without saying that the invention is not limited to the embodiment described above as an example but that it encompasses all variants.
