Description

Title of the invention: Container open at two ends and resealable by a dispensing cap

[0001] The present invention relates to the field of containers for liquid cosmetic products.

[0002] More specifically, the invention relates to a container for a liquid cosmetic product whose internal volume must be refilled with liquid cosmetic product for subsequent use by a user. To this end, the main bottle may, for example, be provided with a dispensing means for delivering the liquid cosmetic product contained in the internal volume of the main bottle to the user, such as a pump, a dispensing cap, or the like.

[0003] A cosmetic product is in particular a product as defined in Regulation 20 EC No 1223 / 2009 of the European Parliament and of the Council dated 30 November 2009 on cosmetic products.

[0004] Furthermore, the term "fluid" cosmetic product should be understood to mean a cosmetic product capable of flowing under its own weight. Generally speaking, a fluid cosmetic product is understood to be a liquid or viscous cosmetic product whose maximum consistency at room temperature (25°C) is such that it can flow under its own weight. By way of example, such a product may be in the form of a liquid with a viscosity on the order of magnitude of that of water, for example, between 1 and 10 times the viscosity of water, a foam, a cream, a paste, or a gel.

[0005] In this field, containers for fluid cosmetic products are known, comprising a main body defining an internal volume adapted to receive the fluid cosmetic product and extending along a longitudinal axis between a first end, called the distribution end, having a distribution orifice in fluidic communication with the internal volume, and a second end opposite to the first end; said container being able to adopt a storage configuration and a distribution configuration, and being provided with a first sealing element adapted to close the distribution orifice in the storage configuration and to clear the distribution orifice in the distribution configuration.

[0006] Documents WO9530590A1, US2005067046A1, WO2013136491A1 and WO2016031429Al describe examples of such a container whose main body is in the form of a flexible pouch made of two sheets sealed together to define an internal volume, and of which a portion is designed to be cut out to provide an opening for dispensing the liquid cosmetic product contained within. pouch. Thus, to refill a main bottle, the user of such a flexible pouch cuts out a part of the pouch giving access to its internal volume through a dispensing orifice, places this dispensing orifice opposite the opening of a main bottle and exerts pressure on the flexible pouch or rolls the flexible pouch on itself, in order to cause the liquid cosmetic product to exit from the internal volume of the flexible pouch into the internal volume of the main bottle.

[0007] A container of the aforementioned type is also known from document WO2021085362A1. The main body of this container is formed of two relatively rigid shells joined together to define an internal volume, and a portion of this portion is designed to be cut out to provide a dispensing orifice for the liquid cosmetic product contained in the main body. To refill a main bottle, the user of such a container cuts out a portion of the main body, forming a dispensing cannula that provides access to its internal volume through a dispensing orifice. This dispensing orifice is then positioned opposite the opening of a main bottle, and the liquid cosmetic product contained in the container's internal volume is poured into the main bottle by gradually tilting the container relative to the main bottle until the container is completely empty.

[0008] Such containers, whether in the form of a flexible pouch or a relatively rigid shell, present a number of drawbacks, particularly in terms of yield rate, i.e., the capacity of the internal volume to be completely emptied of the liquid cosmetic product it contains, as well as ease and cleanliness of use. The invention aims in particular to provide a container of the aforementioned type that is reusable after complete or partial use, so as to save cosmetic product.

[0009] The development of eco-responsible, environmentally friendly solutions, whose design and development take environmental issues into account, is becoming a major concern in order to help meet global challenges. It is therefore essential to design products that reduce the amount of materials used and / or replace them with more environmentally friendly materials and / or use recyclable materials in order to decrease the product's carbon footprint and / or reduce its environmental impact.

[0010] In this context, it is important to develop products that generate less waste, particularly those optimized for the quantity of products transported, notably by redesigning and / or resizing them to reduce the volume and weight of packaging. The objective is to offer eco-responsible, reusable products, particularly those that can be recharged at home or in stores, in order to reduce the carbon footprint of the products.

[0011] In order to overcome all or part of these drawbacks, the present invention proposes a container for a fluid cosmetic product, comprising a main body defining an internal volume adapted to receive the fluid cosmetic product and extending along a longitudinal axis X between: a first end, called the dispensing end, having a dispensing orifice in fluidic communication with the internal volume, and a second end opposite the first end; said container being able to adopt a storage configuration and a dispensing configuration, and being provided with a first sealing element adapted to close the dispensing orifice in the storage configuration and to open the dispensing orifice in the dispensing configuration, the second end of the main body is an air intake end and has an air intake orifice in fluidic communication with the internal volume,and the container is provided with a second sealing element adapted to close the air intake opening in the storage configuration and to open the air intake opening in the dispensing configuration, so that the transition from the storage configuration to the dispensing configuration and the opening of the dispensing opening and the air intake opening by the first and second sealing elements causes the liquid cosmetic product contained in the internal volume of the container to flow by gravity; the container can be resealed by the second sealing element after complete or partial drainage of the cosmetic product.

[0012] Thanks to these provisions, the invention offers a container for fluid cosmetic product, whose rate of restitution, simplicity, ergonomics and cleanliness of use are improved.In particular, the implementation within the container according to the invention of an air return orifice opposite the dispensing orifice allows, when the air return orifice is cleared by the sealing element associated with it and the dispensing orifice is placed in fluidic communication with the internal volume of the main bottle after clearing of the associated sealing element, to cause a continuous and substantially laminar gravity flow of the fluid cosmetic product received in the internal space of the container towards the internal volume of the main bottle to be refilled, avoiding any bubbling phenomenon, due to an air return through the dispensing orifice which would take place during the flow of the product out of the container, slowing down this flow, or stagnation of residual cosmetic product inside the container, if this container were devoid of such an air return orifice.Thus, the container according to the invention makes it possible to achieve an improved, if not substantially complete, restitution rate by simple gravity flow of the fluid cosmetic product it contains, without requiring any particular deformation of its main body to cause the fluid cosmetic product to come out, in a reduced time and minimizing the risk of. soiling or spillage of the cosmetic product outside the main bottle to be refilled while avoiding the bubbling phenomenon due to air intake at the dispensing orifice, the air intake taking place through the air intake orifice at the second end of the main body, opposite the first end of the main body equipped with the dispensing orifice.

[0013] Thanks to these provisions, the invention offers a container for liquid cosmetic products, the yield rate, simplicity, ergonomics, and cleanliness of which are improved because the container is resealable via the second sealing element. In particular, product savings can be achieved because any unused product can be stored in the container for future use instead of being discarded in the event of partial use. Similarly, the container can be resealed for refilling and reuse in the event of complete product use.

[0014] Preferably, the dispensing orifice and / or the air return orifice are centered on the longitudinal axis of the main body of the container. This promotes the speed and laminar flow of the liquid cosmetic product out of the container, as well as the balancing of the container, which is advantageous for its connection to the main bottle.

[0015] In a conventional manner, the main bottle extends along a longitudinal axis, defines an internal volume and includes a neck delimiting an opening, a bottom and a side wall connecting said bottom to said neck by being connected to the latter by a shoulder.

[0016] Furthermore, preferably, the first end of the main body includes a dispensing cannula with a dispensing orifice, the outer diameter of which preferably corresponds substantially to the inner diameter of the neck of the main bottle. These arrangements further improve the reliability of the coupling between the container and the main bottle and limit the risk of the main bottle being contaminated by the cosmetic product during a refilling operation. This is achieved by providing a dispensing cannula on the container adapted to be inserted at least partially into the opening of the neck of the main bottle, thus ensuring a clean and spill-free transfer of the liquid cosmetic product from the container to the main bottle.Furthermore, the implementation of such a dispensing cannula helps to limit the risk of the container tipping around an axis perpendicular to the longitudinal axis when coupled to the main bottle, and thus to improve the stability of the assembly formed by the container coupled to the main bottle.

[0017] In a particularly advantageous embodiment, especially with regard to reducing the environmental impact of the container, both during its manufacture and its transport and distribution, or at the end of its life, the main body comprises an inner layer adapted for contact with the liquid cosmetic product and made, for example, of plastic, and an outer layer made, for example, of a cellulosic material, such as paper, cardboard, or paper or cardboard pulp, or of plastic. The inner layer only provides a sealing and impermeability function against oxygen and water vapor for the cosmetic product contained within the main body of the container, and not a structural function for the container, this function being primarily ensured by the outer layer. Therefore, the amount of plastic used to make the container can be minimized, particularly by using a cellulosic material, especially recycled and / or recyclable, for the outer layer.

[0018] According to a particularly advantageous embodiment of the invention, the dispensing orifice has a first cross-section, and the air return orifice has a second cross-section smaller than or equal to the first cross-section. By providing a larger area, a larger cross-section for the flow of the fluid cosmetic product, at the air return orifice than at the dispensing orifice, it is ensured that the flow of the fluid cosmetic product through the dispensing orifice is not limited or hindered by the air intake capacity of the main body of the container through the air return orifice. The emptying rate of the main body of the container is thus optimized. Advantageously, the cross-section of the air return orifice is greater than or equal to twice the cross-section of the dispensing orifice. For example, the cross-section of the dispensing orifice is approximately 5 mm² and the cross-section of the air return orifice is approximately 10 mm².

[0019] In particular, the internal volume of the main body contains a fluid cosmetic product having a viscosity at room temperature (20°C) between 0.001 Pa.s and 10 Pa.s.

[0020] Preferred embodiments

[0021] Preferably, the container according to the invention has one or more of the following characteristics, taken alone or in combination:

[0022] The first sealing element is detachable from the first end.

[0023] It can be resealed by the first sealing element after a complete or partial flow of the cosmetic product.

[0024] The second sealing element includes a second cover suitable for assembly at the second end by screwing, snapping, press fitting, clipping, in storage configuration.

[0025] The first sealing element comprises a first cover suitable for being assembled at the first end by screwing, snapping, press fitting, clipping, in storage configuration.

[0026] It forms a resealable refill.

[0027] It forms a primary pack.

[0028] The main bottle extends along a longitudinal axis X, defining an internal volume and comprising a neck delimiting an opening, a base, and a side wall connecting said base to said neck by means of a shoulder. The first end of the main body comprises a dispensing cannula having the dispensing orifice, and whose outer diameter preferably corresponds substantially to the inner diameter of the neck of the main bottle. This structure maximizes the flow diameter of the formula, eliminating the need to leave a gap to allow air to rise into the refill.

[0029] The distribution cannula is connected to a lateral wall of the main body by a flat shoulder.

[0030] It is compressible.

[0031] The second shutter element is hinged on the main body.

[0032] The second shutter element is made in one piece with the main body and includes a hinge, preferably a film hinge or two flexible strands.

[0033] The second cover is designed to remain open without user intervention.

[0034] The second cover is offset from the longitudinal axis (X), which facilitates its grasping by the user.

[0035] At least one of the first sealing element and the second sealing element is permanently connected to the main body.

[0036] At least one of the first shutter element and the second shutter element includes a service capsule.

[0037] The distribution orifice has a first section, the air return orifice has a second section less than or equal to the first section.

[0038] The internal volume of the main body contains a fluid cosmetic product having a viscosity at room temperature (20°C) between 0.001 Pa.s and 10 Pa.s.

[0039] The invention also proposes an assembly comprising a container as described above and a main bottle extending along a longitudinal axis, defining an internal volume and comprising a neck delimiting an opening, a base, and a side wall connecting said base to said neck by means of a shoulder. According to an advantageous arrangement, the internal volume of the main bottle is greater than or equal to, and preferably substantially equal to, the internal volume of the main body of the container. Thus, the container constitutes a refill for the main bottle, which can, in particular, be single-use and discarded once the liquid cosmetic product it contains has been transferred into the main bottle. By way of example, the internal volume of the main bottle and the internal volume of the container are approximately 30 mL.

[0040] Furthermore, the present invention also relates to a method of using such an assembly, comprising the steps, preferably successive, of: providing a main bottle whose internal volume must be refilled with fluid cosmetic product; provide a container of fluid cosmetic product; uncover the dispensing orifice with the first sealing element; place the main body of the container on the main bottle, aligning the dispensing orifice of the main body with the neck opening, specifically aligning the longitudinal axis of the main body with the longitudinal axis of the main bottle; uncover the air return orifice with the second sealing element, so as to cause the fluid cosmetic product contained in the internal volume of the container to flow by gravity into the internal volume of the main bottle; close the air return orifice with the second sealing element when a desired quantity of cosmetic product has flowed into the main bottle.

[0041] The invention also relates to a resealable refill comprising a container of fluid cosmetic product as defined above.

[0053] Fig. 1 illustrates in perspective a particularly advantageous embodiment of the container 1 for a fluid cosmetic product according to the invention.

[0054] As can be seen in particular in this [Fig. 1], as well as in Figures 2 to 4,

[0055] The container 1 according to the invention comprises a main body 2, defining a internal volume 20 suitable for receiving a fluid cosmetic product P with which one wishes to refill the internal volume of a main bottle.

[0056] The main body 2 of the container 1 extends along a longitudinal axis X between a first end 21, the distribution end of the fluid cosmetic product P, and a second end 22, opposite the first end 21 and called the air intake end.

[0057] As shown in particular in [Fig. 2], the first end 21 of the main body 2 has a distribution orifice DO, in fluidic communication with the internal volume 20 of the main body 2 and through which the fluid cosmetic product P contained in the internal space 20 of the main body can be distributed out of the container 1, in particular towards a main bottle to be refilled. The second end 22 of the main body 2 has an air return orifice VO, in fluidic communication with the internal volume 20 of the main body 2 and through which air is admitted into the internal volume 20 of the main body 2 as the fluid cosmetic product contained within it flows out of the internal volume 20 of the main body 2 through the distribution orifice.

[0058] As can be seen in particular in [Fig.2], the distribution orifices DO and the air return orifice VO are aligned with each other and centered on the longitudinal axis X of the main body 2. The invention could also be implemented with distribution orifices DO and air return VO eccentric with respect to the longitudinal axis X.

[0059] The container 1 according to the invention can adopt a storage configuration, in which the fluid cosmetic product P is received in a sealed manner in the internal volume 20 of the main body 2 and a distribution configuration, in which the fluid cosmetic product P contained in the internal volume 20 of the main body 2 can be distributed outside the main body 2 through the distribution orifice DO.

[0060] For this purpose, the main body 2 of the container 1 according to the invention is provided with a first sealing element 3 adapted to seal the distribution orifice DO in storage configuration and to clear the distribution orifice DO in distribution configuration.

[0061] Furthermore, and according to the invention, the main body 2 of the container 1 is provided with a second sealing element 4 adapted to seal the air return orifice VO in storage configuration and to clear the air return orifice VO in distribution configuration.

[0062] Thanks to these arrangements, the passage of the container 1 from its storage configuration to its distribution configuration, by the release of the first and second sealing elements 3, 4 respectively from the distribution orifice DO and the air intake orifice VO, causes the flow by gravity of the fluid cosmetic product P contained in the internal volume 20 of the main body 2 of the container 1, through the distribution orifice DO, in particular towards the main bottle to be refilled.

[0063] In the embodiment illustrated in figures 1 to 4, the main body 2 and more broadly the container 1 is made in the form of a cylindrical container, in particular from a sheet of thermoplastic material.

[0064] The second sealing element 4 advantageously comprises a dispensing cap forming a dispensing head with a cover 8 connected to a base portion by a film hinge 28. The cover 8 has a pin arranged to hermetically seal the air intake VO when folded down onto the base portion. The cover 8 forms a movable portion hinged to said base portion. The cover 8 is integral with the base portion. In particular, the cover is shaped in a complementary manner with respect to the base portion. The pin may be provided with a snap-locking ridge.

[0065] The first sealing element includes in particular a stopper or a service cap.

[0066] Advantageously, the main body 2 and more generally in the illustrated embodiment the container 1 has a structure comprising an inner layer adapted for contact with the fluid cosmetic product P and made for example of plastic material, and an outer layer made for example of cellulosic material, such as paper, cardboard or paper or cardboard pulp, or of plastic material.

[0067] The container 1 according to the invention is intended to constitute a refill of fluid cosmetic product P for a main bottle. As shown in Figures 7 to 10, illustrating successive steps of refilling with cosmetic product using the container according to the invention, the main bottle 10 to be refilled extends along a longitudinal axis X', defines an internal volume 100 adapted to receive the fluid cosmetic product P and includes a neck 11 delimiting an opening O, a base 12 opposite the opening along the longitudinal axis X' and a side wall 13 connecting the base 12 to the neck 11 by being connected to the neck 11 by means of a shoulder 14.

[0068] According to a particularly advantageous provision of the invention, the container 1 is provided with means to facilitate and make reliable the coupling of the container 1 in dispensing configuration and the main bottle 10 to be refilled with fluid cosmetic product P.

[0069] Thus, and as can be seen in particular on [Fig. 1], the first end 21 of the main body 2 advantageously includes a receiving housing centered on the distribution orifice DO, adapted to receive the neck 11 of the main bottle 10 and whose external radial dimension dr preferably corresponds substantially to the external diameter De of the neck of the main bottle 10.

[0070] Furthermore, and as can be seen in particular in [Fig. 2], the first end 21 of the main body 2 comprises a dispensing cannula 212 having the dispensing orifice DO, and whose outer diameter preferably corresponds substantially to the inner diameter Di of the neck 11 of the main bottle 10 mentioned in [Fig. 5]. In this way, when the container 1 is placed on the main bottle 10, the dispensing cannula 212 is inserted through the opening O into the neck 11 of the main bottle 10, with some play, with a slight rubbing contact or even with slight tightening.

[0071] Advantageously, and as illustrated in [Fig.2], the dispensing cannula 212 having the dispensing orifice DO extends along the longitudinal axis X. This ensures that the dispensing orifice DO is located inside the neck 11 when the container 1 is coupled to the main bottle 10 to be refilled along the longitudinal axis X, as can be seen in particular in Figures 5 and 6.

[0072] According to a particularly advantageous arrangement, the cross-sectional area S2 of the air return orifice VO is preferably less than or equal to the cross-sectional area SI of the distribution orifice DO. For example, the cross-sectional area SI of the distribution orifice DO is approximately 5 mm² and the cross-sectional area S2 of the air return orifice VO is approximately 10 mm².

[0073] The fluid cosmetic product P intended to be contained in the container 1 and transferred to the main bottle 10 preferably has a viscosity at room temperature (20°C) of between 0.001 Pa.s and 10 Pa.s. Such a fluid cosmetic product P may, for example, be a body hygiene composition, such as a shower gel or cream, a makeup composition, such as a liquid foundation, a skincare composition, such as a serum or other, or a hair product, such as a shampoo or hair coloring product.

[0074] We will now describe in relation to figures 7 to 10 the different successive stages of use of an assembly comprising a container 1 of fluid cosmetic product P and a main bottle 10 to be refilled with product.

[0075] In a first step, illustrated in [Fig. 7], a main bottle 10, the internal volume 100 of which is empty and to be filled or refilled with fluid cosmetic product P, is provided, as well as a container 1 as described previously. The first sealing element 3 is detached from the main body 2 of the container 1, so as to release the distribution orifice DO of the main body 2. The first sealing element 3 detached from the main body 2 can then be discarded or kept for reuse.

[0076] In a second step, illustrated in [Fig. 8], the container 1 is positioned and coupled onto the main bottle 10 to be refilled by lifting the second sealing element 4, i.e., by opening the dispensing cap to begin filling. Furthermore, the longitudinal axis X of the main body 2 of the container 1 is aligned with the longitudinal axis X' of the main bottle 10, and the dispensing orifice DO of the main body 2 of the container is aligned with the opening O of the neck 11 of the main bottle 10.

[0077] More specifically, when the container 1 is coupled to the main bottle 10, the container 1 is moved along the longitudinal axis X towards the main bottle 10 as shown in [Fig. 9]. In this dispensing configuration, with the dispensing orifices DO and air return VO unobstructed, the fluid cosmetic product P is free to flow simply under the effect of gravity through the dispensing orifice DO into the internal volume 100 of the main bottle 10, until the internal volume 20 of the main body 2 of the container is completely emptied, as illustrated in [Fig. 10].

[0078] Advantageously, the internal volume 100 of the main bottle 10 is substantially equal to the internal volume 20 of the main body 2 of the container 1. As an example, the internal volume 100 of the main bottle 10 and the internal volume 20 of the main body 2 of the container 1 are close to 30 ml.

[0079] The main body 2 of the container 1 can then be separated from the main bottle 10 after closing the second sealing element if desired.

[0080] Finally, the neck 11 of the main bottle 10 can be closed, for example by means of a stopper, or be equipped with a distribution means, such as a pump, a dispensing cap or other, allowing the distribution of the fluid cosmetic product P outside the main bottle 10.

[0081] The invention has been illustrated by an example concerning a refill. The container could be a primary pack, for example a shampoo bottle.

[0082] The invention is not limited to the illustrated embodiments. Other display presentations are in particular part of the present invention. Those skilled in the art will understand that the embodiments described above can be combined to form new embodiments provided they are technically compatible.
