Abstract

The invention relates to a housing for a refillable cosmetic product container device. The housing (8) is configured to receive a refill configured to contain said cosmetic product. The housing (8) comprises an opening (9) forming a neck (11) of the housing and configured to receive the refill so as to place the refill in position in a receiving volume defined by an inner wall (14) of the housing. The housing further comprises a ring (17) connected to the neck (11), said ring (17) at least partially covering a portion of the inner wall of the housing forming said neck (11). The ring comprises an inner surface (18) to which is connected a member (19) of elastomeric material at least partially protruding with respect to said inner surface of the ring. The thus formed housing (8) is able to retain the refill in the receiving volume by virtue of the protrusion of the member of elastomeric material formed on the inner surface of the ring. The invention also relates to a cosmetic product container device comprising such a housing (8) and a refill.

Description

[0001] This invention relates to the field of refillable container devices for cosmetic products. Specifically, "cosmetic products" means all products used for applying makeup to the skin (including lips) and all compositions provided for application to the body, including so-called care products (such as moisturizers). This invention particularly relates to the field of refillable components for refillable container devices for cosmetic products.

[0002] Containers for cosmetic products are generally defined as any container used to hold cosmetic products for their preservation, transport, commercialization, or use. For example, jars, bottles, boxes, etc., used to hold cosmetic products are thus specified.

[0003] "Refill" means a removable component that is adapted to contain a cosmetic product and can be placed in place and removed from the housing (which forms the outer surface of the refillable cosmetic product container device consisting of the housing and the refill).

[0004] Once in place within the housing, the refill must be properly held within it. In particular, it is crucial to prevent the refill from detaching from the housing during transport or use, as the can may be in any orientation during transport or use, especially if the container assembly is completely overturned, whether intentionally or not. Furthermore, the refill should not move within the housing while the container assembly is in use. The refill must remain secured during product dispensing (e.g., when the user removes product from the refill).

[0005] However, in order to replace the refill, the refill must be easily removed from the housing.

[0006] Known refillable container devices typically include systems for retaining the refill within the housing, which are visible and aesthetically unappealing, and / or require complex or costly industrial modifications.

[0007] Document JP 2013119399 therefore discloses a can for cosmetic products, the can including a refiller, the refiller being generally shaped as a rotating cylinder, and including a protrusion that slides in a vertical groove provided in the outer shell of the can by means of a matching shape to prevent the container from rotating.

[0008] Document EP 0661012 also discloses a can device with a refilling element, the can device including an inner vessel or reservoir that is engaged in a matching shape within an outer reservoir forming a shell, in particular, the inner reservoir may include a peripheral protrusion that engages with a groove formed in the neck of the outer reservoir.

[0009] Document WO 2019058087 also discloses a can device with a refilling element in a closed configuration, the can device comprising an inner vessel or reservoir that is fitted in a matching shape into an outer reservoir forming a shell, the shell including a peripheral flange that engages with a groove formed on the outer surface of the vessel. The upper portion of the shell has a neck including a groove into which a radial flange of the vessel is inserted to keep the vessel from rotating.

[0010] Therefore, known container devices with refillable parts in the prior art are based on the shape matching between the shell and the refillable part, which allows the refillable part to be held in the shell, for example, by clamping (i.e., snap-fit ​​engagement or other relative mechanical engagement). This requires a shell and refillable part of a specific shape, which, for example, prevents the formation of refillable container devices using shells of conventional shapes (such as standard glass containers), and similarly prevents the use of refillable parts in the form of vessels of conventional shapes (such as conventionally shaped glass or stainless steel vessels).

[0011] The present invention aims to overcome all or part of the above-mentioned disadvantages.

[0012] Therefore, the present invention relates to a housing for a refillable container device for cosmetic products, the housing being configured to receive a refill, the refill being configured to contain the cosmetic product. The housing includes an opening forming a neck, the opening being configured to receive the refill so as to place the refill in place within a receiving volume defined by an inner wall of the housing. The housing further includes a ring connected to the neck, the ring extending over at least a portion of the inner wall of the housing forming the neck. The ring includes an inner surface to which a member of an elastomeric material is connected, the elastomeric material member at least partially projecting relative to the inner surface of the ring.

[0013] The resulting housing can hold a properly shaped refill in place using components made of elastomeric material. This retention (which still allows for refill removal) utilizes the elastic properties and coefficient of friction of the elastomeric material. Therefore, the use of the refill is very simple. Because the elastomeric material components are supported on a ring mounted on and attached to the housing, the invention can be implemented on housings with very different configurations and shapes.

[0014] Components made of elastomeric materials can be molded onto rings.

[0015] The ring can be formed from a plastic material. The ring and its elastomeric components can be formed together by two-material injection molding.

[0016] Therefore, rings can be produced through known and mastered industrial processes that provide good cohesion between the ring and the components of the elastomeric material it supports.

[0017] The elastomer material used can be, for example, a thermoplastic elastomer or a silicone elastomer. It can have a hardness between 20 and 80 Shore hardness, preferably between 40 and 60 Shore hardness.

[0018] The elastomer material used and its hardness enable it to deform under reasonable forces compatible with those applied to the refill of cosmetic products.

[0019] Components made of elastomeric materials can form discontinuous protrusions distributed on the surface of the inner wall of the shell.

[0020] The elastomeric material component may form at least two protrusions, preferably at least three protrusions, which are distributed on the periphery of the inner surface of the ring in the portion of the ring located on the inner wall of the neck of the outer shell.

[0021] The elastomeric material components may extend in one or more strips parallel to the opening of the shell.

[0022] Different configurations of elastomeric material components allow the support area to adapt to the application of refilled components, retaining force, aesthetics, and implementation complexity.

[0023] In such a casing, the receiving volume can have the general shape of a cylinder of revolution or a truncated cone or a right prism.

[0024] These are configurations particularly well-suited for implementing the present invention.

[0025] The outer shell can be made primarily of plastic, glass, stainless steel, aluminum, or wood.

[0026] "Mainly" means more than 50% by volume. Specifically, apart from components made of ring and elastomeric materials, the outer shell can be formed from one of the aforementioned materials. In fact, the outer shell possesses an aesthetic aspect, which is perhaps the most important in the cosmetics industry.

[0027] The ring can be attached to the neck of the housing via snap-fit ​​and / or adhesive bonding. Any other known reliable rigid connection method can also be used.

[0028] When bonding is performed between the ring and the neck, bonding can be performed between the ring and the outer wall of the housing, and / or between the ring and the inner wall of the housing, and / or on the periphery of the neck of the housing.

[0029] The present invention also relates to a container device for a cosmetic product, the container device comprising a shell as defined above and a refill, wherein the refill includes a sidewall having a gap relative to the inner wall of the shell, except at all or part of the location of the elastomeric material component, such that a support region of the elastomeric material component is formed on the sidewall of the refill.

[0030] Since the refill material is held in the support area within the housing, the means of holding it in place can be invisible (if the housing is opaque) or at least highly discontinuous, so that they do not compromise the aesthetics of the constructed can.

[0031] Compared to the configuration of elastomeric material components when not subjected to external forces, elastomeric material components can deform in the support region by being compressed against the sidewalls of the refill.

[0032] The deformation of the elastomeric material component in the support area increases the force it applies to the inner surface of the housing, thereby increasing the frictional force resisting the removal of the refill.

[0033] In one embodiment, the sidewall of the refill component is free of protrusions or recesses, such as snap-fit ​​rings, studs, orifices, or grooves, at least in the area where the sidewall interacts with the elastomeric material component. Specifically, the sidewall of the refill component is free of protrusions or recesses below any component (edge, peripheral flange, etc.) of the vessel configured to be vertically engaged with the outer shell.

[0034] Not based on snap-fit ​​or screw engagement principles or other engagements of a component in a matching-shaped component, the retention of the refill does not require forming any particular shape thereon that is configured to cooperate with the housing's retention mechanism.

[0035] In a container device as defined above (the refill container of which is filled with cosmetic product), the outer shell and the refill can be configured such that the force required to remove the refill is greater than or equal to twice the weight of the refill, preferably greater than or equal to two and a half times the weight of the refill. In particular, the shape, size, and configuration of the elastomeric material components are configured to obtain the force required to achieve the desired removal of the refill.

[0036] This holding force allows for relatively easy removal and replacement of the refill. This corresponds to the ideal specifications for conventional containers used in cosmetic products.

[0037] Finally, in the container device described above, the vessel may include a lid that is fastened to the rest of the vessel by snap-fit ​​or screw engagement. This allows the vessel to be used alone, without an outer casing, to transport the cosmetic products it contains.

[0038] The container device can be, in particular, a can, such as a frost can.

[0039] Other features and advantages of the present invention will become apparent in the following description.

[0040] The accompanying drawings are provided by way of non-limiting example:

[0041] Figure 1 A first example of a refill component that can be implemented in a container device for cosmetic products according to an embodiment of the present invention is shown in a three-dimensional view.

[0042] Figure 2 A first example of a housing for a refillable cosmetic product container device according to a first illustrative embodiment of the present invention is shown in three-dimensional view.

[0043] Figure 3 A cross-sectional view shows a cosmetic product container device, namely a can, which includes... Figure 2 The outer shell and Figure 1 Refill components;

[0044] Figure 4 Shown in partial cross-sectional view Figure 3 The interaction between the outer shell and the refill component in the container assembly;

[0045] Figure 5 Is Figures 2 to 4 A schematic view of the ring implemented in an embodiment of the present invention.

[0046] Figure 1 A first example of a refiller 1 configured for use in a refillable cosmetic product container device according to an embodiment of the present invention is shown in a three-dimensional view.

[0047] The refill component 1 includes a vessel 2, which is hollow, meaning that the shape of the vessel forms a space configured to receive cosmetic products. In the example shown here, the vessel 2 has a general cylindrical shape, which can be a straight prism or slightly flared (truncated cone). However, any hollow shape can be envisioned to form the vessel, particularly any right prism shape, especially having a shape that is square, rectangular, pentagonal, hexagonal, octagonal, etc.

[0048] The vessel 2 has a side wall 3 and a bottom 4.

[0049] In the example shown, the vessel includes an upper edge 5. The upper edge 5 is formed around the opening surface 6 of the vessel 2.

[0050] According to an embodiment not shown, the upper edge 5 may protrude, that is, it forms an edge around the opening surface 6. Such an edge allows the lid to snap onto the vessel 2. When the vessel is inserted into the corresponding outer shell, this edge also forms a support area for the vessel.

[0051] In the illustrative embodiment shown here, the vessel 2 has a thread 15 that allows it to be fitted with a lid that screws onto the vessel. The vessel 2 can therefore be distinguished independently from the description below. Figure 2 The described outer shell is used alone for transporting cosmetic products contained in the container.

[0052] Cosmetic products, such as creams, can therefore be contained within the space formed inside the vessel.

[0053] The opening 6 of the container may be covered with a removable cap, such as a plate for protecting the product, which is supported, for example, on the upper edge 5 and / or on a shoulder formed in the upper portion of the container. The container may also include a closure, such as a heat-sealed closure, that covers the opening 6 and must be removed when the refill is used for the first time. The opening may be unobstructed, thus directly exposing the product contained in the container 2 of the refill, or it may be equipped with a regulating device, such as a sieve, mesh, or other device configured for dispensing the product. The refill therefore has a simple shape.

[0054] Here, the refill, especially its sidewall 3, and more particularly the outer surface 7 of the sidewall 3, has no protrusions or other snap-fit ​​fastening devices.

[0055] "Uneven body" means a hollow or protruding block or component formed on a surface and whose dimensions are substantially larger than the possible roughness associated with the material constituting the surface. The sidewall 3 surface specifically excludes snap-fit ​​rings, pins, openings, or any grooves.

[0056] In the illustrative embodiment shown here, the sidewall 3 still includes a peripheral protrusion 16 that provides a supporting surface. Therefore, the sidewall 3 does not have any means for snap-fit ​​engagement with the housing configured as the receiver dish 2, as detailed below.

[0057] Refill components can therefore be easily manufactured, or can be made from standard containers such as plastic cans, glass cans, or stainless steel cans.

[0058] As a refill, a pre-existing container that has not been modified, such as a conventional glass container, can be used as a refill for cosmetic product container devices.

[0059] Therefore, the manufacturing cost of the vessel (and the final container) can be reduced compared to a container device that must include specific components for fastening it inside the shell.

[0060] Figure 2 This illustrates an example of housing 8, which can be used to form a structure having a refill element 1, for example... Figure 1 A container device (here, a can) for cosmetic products that requires refilling.

[0061] The term "shell" specifically refers to a component configured to receive a refill and in which the refill will be held. Therefore, Figure 2 The outer shell of the vessel 2 is configured to receive the receiving volume of the refill 1 through the opening 9. More specifically, the inner wall 14 of the outer shell of the vessel 2 defines the receiving volume of the refill 1 in the vessel 2.

[0062] The outer casing 8 includes a body 10. In the example shown, the body 10 is substantially prismatic in shape, with a square base and slightly convex sides. Since the outer casing 8 forms the visible part of the can, it has an important aesthetic function once the can is constructed. The body 10 of the outer casing 8 has a neck 11 at the top, which is provided with threads 12, allowing the screw cap to be screwed on. Figure 2 (Not shown in the image) Assembled in place.

[0063] A shoulder 13 is formed near the mouth of the neck 11. The shoulder 13 is sized to receive the components of the vessel 2 supported thereon, namely the peripheral flange 16 in the schematic embodiment shown.

[0064] The shoulder 13 is optional. In other embodiments, the refiller can be vertically supported on other surfaces of the housing. For example, the upper edge 5 of the vessel 2 of the refiller 1 can be directly supported on the neck 11, or, for example, if the vessel 2 of the refiller has no edge, the bottom 4 of the vessel can be supported on the bottom of the housing if the housing includes a bottom. A bottomless housing 8 can facilitate the removal of the refiller.

[0065] More specifically, according to the invention, the housing 8 includes a ring 17 attached to the neck 11. In the illustrated example, the ring 17 covers the neck 11 and is attached to the neck by a snap-fit ​​engagement. Alternatively, or in addition to snap-fit ​​engagement, other types of connections, such as adhesive, may be used.

[0066] The ring 17 here includes a shoulder 13, which enables the vessel 2 of the refilling component to be vertically supported.

[0067] According to the present invention, the ring 17 includes an inner surface 18 to which an elastomeric material member 19 is attached.

[0068] The elastomeric material component 19 is tightly connected to the ring 17.

[0069] Typically, the component 19 of the elastomeric material can be molded onto the ring 17.

[0070] The component 19 of the elastomeric material can be molded onto the ring 17, particularly onto the ring 17 made of plastic material, especially hard plastic material (such as polypropylene).

[0071] Alternatively, the ring 17 and the component 19 of the elastomeric material can be formed by two-material injection molding.

[0072] The elastomeric materials that can be used to form components include thermoplastic elastomers (TPEs) and silicone elastomers. The available materials advantageously have a Shore hardness between 19 and 80 degrees (preferably between 40 and 60 degrees).

[0073] The hardness of the material used is an important parameter for optimization, and is selected in particular based on the size of the refill vessel and the material used to form ring 17 and the configuration of the ring.

[0074] The elastomeric material component 19 protrudes relative to the inner surface 18 of the ring 17.

[0075] In other words, at least a portion of the elastomeric material component 19 is raised relative to the inner surface 18.

[0076] In the illustrated schematic embodiment, the elastomeric material component 19 forms a peripheral strip on the inner surface 18 of the ring. This strip includes three protrusions 20 distributed along the periphery of the inner surface 18 supporting the strip.

[0077] These protrusions 20 form portions of the elastomeric material component 19 that function to retain the refill 1 in the receiving volume, as detailed below.

[0078] The number, size, shape, and orientation of the protrusions 20 can vary depending on the application being considered. More generally, there are many possible configurations that can be conceived for components made of elastomeric materials.

[0079] In the illustrated schematic embodiment, the protrusions 20 are arranged vertically, that is, they form elongated protrusions from the top (the opening of the neck 11 of the housing 8) to the bottom (the bottom of the housing 8 (if the housing has a bottom)).

[0080] More generally, the protrusion 20 is oriented perpendicular to the plane formed by the opening 9 of the housing for inserting the refill member 1. Therefore, in this embodiment, the protrusion 20 can be designed as a gadroon.

[0081] In this embodiment, the number of protrusions formed by components made of elastomeric material can be easily adapted with almost no modification to the production tools.

[0082] Except for the protrusion 20, which must protrude relative to the inner surface 8 of the ring 17, the rest of the elastomeric material component 19 may protrude or be flush with the inner surface 18 of the ring 17.

[0083] The distribution of the three protrusions 20 is preferably regular, meaning that these protrusions are equidistant along the strip formed by the member 19 of the elastomeric material. If the ring 17 is circular, then these protrusions are thus formed at an angle of 120° between them. More generally, when the ring 17 is shaped as a surface of revolution, this results in a regular angular distribution of the protrusions 20 within the ring.

[0084] Although in the illustrated embodiment, the elastomeric material member 19 extends continuously in the form of a strip on the periphery of the inner surface 18 of the ring 17, according to another variation of this embodiment, the elastomeric material member 19 may be formed of several protrusions 20 connected together internally by the elastomeric material strip.

[0085] Many other configurations of the elastomeric material component 19 can be envisioned, such as a single strip protruding relative to the inner surface 18 of the ring, a serrated or wavy strip, a combination of one or more strips and protrusions 20, etc.

[0086] Figure 2 The outer shell can be primarily (e.g., except for the ring 17 of the elastomeric material component 19) formed of a variety of different materials. For example, the outer shell can be formed of glass. Glass of any hue can be used, particularly transparent, translucent, opaque, tinted, or untinted glass.

[0087] Depending on the desired appearance, volume, shape, and desired closure, the enclosure can be formed from a variety of other materials. In particular, the enclosure can be made of plastic, wood, or metal (such as stainless steel, tinplate, or aluminum).

[0088] Figure 3 The cross-sectional view shows the result of Figure 2 The outer shell and Figure 1 A container device formed by refilling components, namely a tank.

[0089] Figure 3The container device shown is also equipped with a lid 21, which is configured to cooperate with the thread 12.

[0090] The cross-sectional plane is the radial plane of the outer shell 8, such as... Figure 2 As shown.

[0091] therefore, Figure 3 The tank shown includes a shell 8, which is in the form of a reservoir with thick walls, forming a receiving volume therein for receiving the refill 1.

[0092] In the example shown, the shape of the internal volume of the outer shell 8 thus matches the external shape of the vessel 2 (e.g., cylindrical or slightly truncated conical), with the gap being the only difference. The depth of this volume is slightly greater than the total height of the refill 1, such that the peripheral convex edge 16 of the refill supports the shoulder 13 formed at the mouth of the neck 11.

[0093] Figure 4 It shows the basis with Figure 3 The cross-sectional plane is the same as the cross-sectional plane. Figure 3 A detailed view of the interaction between the outer shell 8 and the refill component 1 in the tank.

[0094] Figure 4 The snap-fit ​​engagement of the ring 17 on the neck 11 of the vessel 2 is shown in particular. For this purpose, the neck 11 can therefore have a shape configured for snap-fit ​​engagement, for example by means of a groove 22 formed in the upper portion of the neck 11.

[0095] Figure 4 The support relationship formed between the peripheral protrusion 16 and the shoulder 13 of the ring 17 is also shown.

[0096] The ring 17 extends along the upper part of the inner wall 14 of the vessel.

[0097] When the refill 1 is in place in the housing 8, in the example shown, its only interaction with the housing is with the ring 17.

[0098] In fact, there is a gap J1 between the inner wall 14 of the outer shell 8 and the outer surface 7 of the side wall 3 of the vessel 2. For example, for a jar of cosmetic cream with a normal volume, such as 60 mL, the gap is on the order of 1 mm to 3 mm.

[0099] An elastomeric material member 19 is disposed on the inner surface of the ring 17. In the illustrated example, a gap J exists between the elastomeric material member 19 and the outer surface 7 of the sidewall 3 of the vessel 2, except for the area protruding from the elastomeric material member 19. In practice, when the protrusions 20 are not subjected to external mechanical stress, and especially when the protrusions 20 are not deformed by compression, each protrusion forms a protrusion with a thickness greater than the gap J.

[0100] For example, the thickness of the protrusion can be on the order of 1 mm, such as 0.9 mm.

[0101] In order to insert the refill 1 into the housing 8 to obtain a support relationship on the shoulder 13, the protrusion 20 needs to be deformed to allow the refill 1 to be inserted into the housing 8.

[0102] When the refill 1 is in the housing 8, each protrusion 20 is compressed and thus has a thickness equal to the gap J. The protrusion 20 thus fills the gap J and, due to its elasticity, exerts a supporting force on the side wall 3 of the vessel 2 of the refill 1.

[0103] Advantageously, several support protrusions are distributed around the vessel 2 so as to distribute the support on the side wall 3 and ensure that the vessel 2 is held effectively and evenly in the outer shell 8.

[0104] exist Figure 5 An example of the distribution of protrusions can be seen in the image. Figure 5 Shown from below Figures 2 to 4 In this embodiment, the ring 17, that is, when the ring 17 is attached to the housing, causes the bottom-oriented surface of the seal to protrude. The three protrusions 20 (which are regularly spaced apart at an angle of 120° between them) enable the vessel 2 to be held evenly and perfectly centered as it is positioned in the housing 8 and interacts with the ring 17.

[0105] Each support region formed at the location of each protrusion 20 forms an area that ensures the vessel 2 (and therefore the refill 1) is held within the housing 8. When a force is applied that tends to remove the refill 1 from the housing 8, a reaction force is created at the location of the protrusion by means of a reaction force, due to the interaction between each protrusion 20 and the sidewall 3 of the refill 1 (to which the protrusion 20 is compressed). This force is generated by the friction of the protrusion 20 against the outer wall of the vessel 2.

[0106] As long as the vessel 2 remains stationary within the outer casing 8, this is known as dry friction. For each protrusion 20, the intensity of this dry friction is at most equal to the static friction coefficient between the protrusions 20 multiplied by the force exerted between the inner wall 14 of the outer casing 8 and the protrusion due to the compression of the protrusions 20. When the force tending to remove the vessel from the outer casing 8 exceeds the sum of the maximum static friction forces applied at the locations of the protrusions 20, the refill 1 begins to move relative to the outer casing 8 to remove it.

[0107] Therefore, the number of protrusions, their size, the elastomer material used, the material constituting the vessel 2, and the state of the outer surface 7 of the sidewall 3 of the vessel are parameters that can adjust the force required to place and remove the refill 1.

[0108] Regarding the elastomeric material component 19, the material it is made of, the total supporting surface area (sum of supporting surface areas) between the elastomeric material component and the outer surface 7 of the side wall 3 of the vessel, and the sum of the forces applied due to the compression of the elastomeric material component are key parameters for determining the configuration of the elastomeric material component.

[0109] Regardless of the implementation method considered, for cosmetic product containers, it is recommended that the force required to remove the refill is at least twice the weight of the entire refill, for example, about two and a half times the weight of the entire refill.

[0110] like Figure 5 In the example shown, the presence of at least three regularly distributed protrusions also allows the refill to be centered in the housing 8, as described above.

[0111] To facilitate placement of the refill 1 into the housing 8, the protrusion 20 in the illustrated example has a dome-shaped form in the so-called vertical direction, which corresponds to the insertion (and removal) direction of the refill 1. This allows for gradual compression of the protrusion as the refill 1 is inserted into the housing 8. The protrusion 20 can alternatively have a beveled or chamfered shape to achieve the same effect.

[0112] This invention is by no means limited to the embodiments detailed above. In particular, the corresponding configurations of the elastomeric material components, refills, and / or housings can be very different from those described above. For example, the presence of protrusions on the elastomeric material components is optional, provided that at least a portion of the elastomeric material component protrudes relative to the inner surface of the housing. A great variety of forms of elastomeric material components are conceivable.

[0113] Several components made of different elastomeric materials can coexist on the same shell.

[0114] Depending on the application being considered, vessels can have different shapes and configurations. Similarly, the outer shell can have different shapes and configurations.

[0115] For example, the vessel can be cubic, cylindrical, cubic or parallelepiped, spherical, and may or may not have a bottom, or have an opening at its bottom to facilitate the removal of the refill.

[0116] Therefore, the present invention enables the removable retention of a cosmetic product's refill component within a housing, resulting in an aesthetically pleasing cosmetic product container that can be refilled by replacing the refill component. Retention is achieved through friction of an elastomeric material component against the outer surface of the refill component's wall. Once the container is constructed, the retaining device, particularly the elastomeric material component, becomes completely invisible and inconspicuous within the housing.

[0117] Furthermore, refills can have shapes that are easy to manufacture because the vessel of the refill is configured to interact with the elastomeric material of the outer shell to retain the outer surface of the refill without requiring any specific mechanical means for snap-fit ​​engagement. Therefore, pre-existing containers (e.g., conventional glass containers, simple plastic containers, metal containers, etc.) can be used as refill vessels for cosmetic product container devices without modification.
