Description

Field of the Invention

[0001] The present invention relates to the field of bottles and jars, and more particularly to the field of jars for cosmetics. In particular, "cosmetics" means all products for making up the skin (including the lips) and all compositions provided for application to the body, including so-called care products (such as moisturizing creams), cleaning products, or products intended to protect the skin from sun damage. Background Art

[0002] Bottles and jars for cosmetics generally include a base that forms a reservoir configured to contain cosmetics, and a neck formed on the base that defines an opening. The base is closed by a lid.

[0003] In a known manner, the neck is substantially cylindrical. In other words, the cross-section of the neck is circular, or the opening defined by the neck is circular. The cylindrical shape of the neck enables the bottle or jar to be simply closed and opened, particularly by screwing the lid onto and off the base. For this purpose, the neck is usually provided with a thread or a spiral ramp.

[0004] However, it may be desirable to manufacture necks of different shapes. In this regard, the necks of known bottles and jars have a non-circular cross-section, particularly a square cross-section that defines a square opening. To enable such bottles and jars to be closed and opened, some solutions of the prior art provide a hinge system that links the base to the lid. There are other alternative closing and opening systems, such as the closing and opening system described in document FR 1551009, which consists of complex and difficult-to-implement additional mechanisms.

[0005] Therefore, the existing solutions for non-cylindrical necks have the disadvantages of being complex and / or requiring the common form of manipulation of closing and opening by rotating the lid on the base of the bottle or jar. Summary of the Invention

[0006] The present invention aims to overcome at least one of the aforementioned disadvantages. In particular, the present invention aims to provide a bottle or jar for cosmetics that has a non-cylindrical neck and enables easy opening and closing while maintaining a simple and natural form of manipulation.

[0007] The present invention relates to a cosmetic bottle or jar, which includes: a base on which a neck is mounted, the neck defining an opening; and a lid configured to close the opening, the neck having a non-circular cross-section, and the neck including an edge that forms a rim on the periphery of the neck.

[0008] According to the present invention, the neck includes at least one first assembly member formed in an outer wall surface of the neck below the edge, the cap includes a profiled wall surface configured to surround the neck when the cap is positioned on the neck in an open position or a closed position, in which open position and closed position the cap closes the opening, the cap includes at least one second assembly member formed in the profiled wall surface, the at least one second assembly member being shaped to be complementary to the at least one first assembly member such that the at least one first assembly member can be assembled with the at least one second assembly member by insertion;

[0009] The cap is configured such that:

[0010] · When the cap is in the closed position:

[0011] ο The at least one second assembly member of the cap is disposed below the edge of the neck, thereby preventing the cap from being vertically removed relative to the neck; and

[0012] ο The at least one second assembly member and the at least one first assembly member are assembled together by insertion to create resistance to relative rotation of the cap and the neck; and

[0013] · When the cap is in the open position, the at least one second assembly member disengages from the at least one first assembly member and the edge of the neck, such that the cap can be vertically removed relative to the neck,

[0014] The cap is configured to be rotated about the neck from the open position to the closed position and vice versa.

[0015] Such a bottle or can having a non-cylindrical neck enables opening and closing movements to be performed in the same way as a conventional bottle or can having a cylindrical neck with the cap screwed onto the base, i.e., for example, rotating counterclockwise to open the bottle or can and rotating clockwise to close the bottle or can.

[0016] Furthermore, since the first and second assembly members are assembled together by insertion to prevent rotation, the user can know when the cap is correctly closed or fastened to the base. This enables unnecessary fastening to be avoided, which may ultimately cause wear of the bottle or can, especially breakage of the seal provided between the cap and the base. This also enables insufficient fastening of the cap on the bottle or can to be avoided, thereby ensuring proper sealing of the bottle or can.

[0017] According to a feature, the profiled wall surface of the cap defines a cavity provided in the cap, the cross-section of the cavity corresponding to the superposition of the cross-section of the neck in a first position and the cross-section of the neck in a second position, the second position being rotated by a predetermined angle relative to the first position.

[0018] Thus, the cap includes a cavity whose dimensions are determined to be able to closely fit the form of the neck.

[0019] According to the feature, the predetermined angle is less than 45° and strictly greater than 0°, preferably equal to 22°.

[0020] According to the feature, the neck has a prismatic cross-section, and the base of the prism has a polygonal shape or a polygonal shape with rounded corners and / or sides.

[0021] According to the feature, the neck has a square cross-section or a square cross-section with rounded corners and / or sides.

[0022] According to the feature, the at least one first assembly member is formed at one or more corners of the cross-section of the neck.

[0023] This facilitates the identification of the position of the at least one first assembly member for closing and opening the bottle or can.

[0024] According to the feature, the neck includes the same number of first assembly members as the number of sides of the polygon.

[0025] According to the feature, the neck has an oval cross-section.

[0026] According to the feature, the cap includes a second assembly member whose number is equal to the number of the first assembly members of the neck.

[0027] According to the feature, the at least one first assembly member includes a protrusion protruding relative to the outer wall surface of the neck, and the at least one second assembly member includes a recess of a corresponding shape, or vice versa.

[0028] According to the feature, the at least one first assembly member includes a notch formed in the neck, and the at least one second assembly member includes a lug of a corresponding shape, or vice versa.

[0029] According to the feature, the at least one first assembly member includes a rotation stopper whose shape is determined to prevent the at least one second assembly member from being supported on the stopper.

[0030] In particular, the rotation stopper enables the prevention of the cap from rotating around the neck when the cap is rotated from the open position to the closed position.

[0031] According to the feature, the at least one second assembly member and / or the at least one first assembly member is elastic.

[0032] According to the feature, the cap includes a cut at the at least one second assembly member, and the cut increases the elasticity of the second assembly member. Description of the Drawings

[0033] Other features and advantages of the present invention will be presented in the following description by way of non - limiting examples with reference to the accompanying drawings:

[0041] - Figure 8 is Figure 1 a cross - sectional view of the bottle - jar of

[0042] - Figure 9 is Figure 1 a cross - sectional view of the bottle - jar of Detailed Description of the Embodiments

[0043] Figure 1 and Figure 2 show a bottle - jar 1 according to an embodiment.

[0044] In the illustrated exemplary embodiment, the bottle - jar 1 is a vessel configured to contain a product that can be directly accessed by a user and is arranged to be retrieved, for example, by a finger or with the aid of a spatula. However, the bottle - jar according to the present invention can be any type of vessel or container. By way of non - limiting example, the bottle - jar can be a vessel provided with a pump or a pipette, enabling access to the product contained therein.

[0045] The bottle - jar 1 includes a base 2 and a cap 3 that enables the bottle - jar 1 to be opened or closed. In this example, the bottle - jar 1 also includes a seal 4 disposed between the base 2 and the cap 3.

[0046] The jars shown in these figures are jars with a square profile. "Square profile" means that the base of the jar has a generally parallelepiped shape with a square bottom, which does not exclude jars with a protruding profile or any other minor variations to the general shape of the jar. Additionally, this specification is made with respect to jar 1 having a square profile, but with the necessary modifications it can be applied to any jar, regardless of the general external shape of the base of the jar.

[0047] In this specification, a "lateral plane" means a plane parallel to the bottom of the base of the jar, and a "vertical plane" means a plane at right angles to the lateral plane.

[0048] Jar 1 is formed symmetrically with respect to the vertical plane here.

[0049] Base 2 is shown separately from two different perspectives, for example, in Figure 3 and Figure 4 Base 2 includes a container 200 and a neck 201, which is mounted on top of the container 200. Neck 201 defines an opening 202, which enables access to the product contained in the container 200. The dimensions of neck 201 and the dimensions of opening 202 are close to the cross-sectional dimensions of base 2. In any case, in the example shown here, opening 202 of jar 1 is wide enough for at least one finger of one hand to pass through, that is, the lateral dimension of the opening in cross-section is greater than or equal to about 25 millimeters.

[0050] Neck 201 includes an outer wall surface 203 and a rim 204, which is formed in the outer wall surface 203. Rim 204 forms a bead around the perimeter of neck 201.

[0051] Here, the outer wall surface 203 is substantially convex in the portion located below the rim 204. This enables the rotational movement of cap 3 on neck 201 to be facilitated.

[0052] Preferably, the upper part of the rim 204 is rounded or beveled to create a ramp effect with the seal 4 when the seal 4 moves vertically against the neck 201.

[0053] Neck 201 has a non-circular (lateral) cross-section. In this exemplary embodiment, neck 201 has a substantially square cross-section. Here, the form of the cross-section of neck 201 is substantially similar to the profile of the base. More specifically, neck 201 includes four identical parts, that is, these four parts have the same form and the same dimensions, and thus together form the sides of a parallelepiped with a generally square bottom surface. The intersections between these parts have rounded corners. These rounded corners facilitate the rotation of the cap around the base.

[0054] Of course, the present specification is applicable to other neck shapes. In particular, the present specification is applicable to any bottle or can having a neck with a non-circular cross-section. By way of example, the neck may have a generally polygonal or oval cross-section. In other words, the neck may have a prismatic form (the base of which is polygonal) or, for example, a cylindrical form (the base of which is non-circular, for example oval).

[0055] The neck 201 includes at least one first assembly member 205. The at least one first assembly member 205 is formed in the outer wall surface 203. The at least one first assembly member 205 is formed here under the edge 204.

[0056] In the example shown, the neck 201 includes four first assembly members 205. The "first assembly member" is used generically to refer to the part of the neck 201 configured to cooperate with the second assembly member carried by the cap 3. The cooperation between the first assembly member and the second assembly member provides or participates in the closing of the bottle or can as described below. Advantageously, the first assembly members 205 are formed at the positions of the corners of the neck 201. This facilitates the identification of the positions of these first assembly members.

[0057] Of course, the number and position of the first assembly members 205 can vary.

[0058] Since the first assembly members 205 are all the same here, only one of these first assembly members will be described.

[0059] The first assembly member 205 includes a stop 206. The stop 206 is a rotational stop such that it is possible to prevent the cap 3 from rotating around the neck 201 when the cap 3 is moved from the open position to the closed position.

[0060] The stop 206 is formed here, for example, by a shoulder provided in the outer wall surface 203 of the neck 201. More specifically, a notch 207 is provided in the outer wall surface 203 such that the neck 201 then has a locally reduced thickness. The face of the neck 201 tangent to the notch 207 then forms the shoulder or stop 206.

[0061] The first assembly member 205 of the neck 201 also includes a protrusion 208 here. The protrusion 208 protrudes relative to the outer wall surface 203 of the neck 201. The protrusion 208 has a semi-cylindrical shape here. The protrusion 208 is tangent to the notch 207.

[0062] The base 2 is formed of any suitable material (in particular, a glass or plastic material). The material may be transparent or opaque. The base 2 may be provided to receive a cosmetic addition or replacement container.

[0063] The cap 3 is in Figure 5 and Figure 6It is shown separately in the figure. The lid includes an upper surface 300, a lower wall surface 301 (on the back of the upper surface 300), and a contour wall surface 302.

[0064] The lid 3 has a square contour here, that is, the upper surface 300 has a square shape. Advantageously, the lid 3 has substantially (or exactly) the same contour dimensions and shape as the base 2.

[0065] The upper surface 300 forms an outer side surface here, and this outer side surface is arranged to be visible to the user when, for example, the bottle or can 1 is closed with the lid 3.

[0066] The lid 3 includes a cavity 303, and this cavity is provided in the lower wall surface 301. The cavity 303 forms the inner part of the lid 3, and this inner part is not visible to the user when the lid 3 closes the opening 202.

[0067] The contour wall surface 302 includes an outer contour surface 302a and an inner contour surface 302b.

[0068] The outer contour surface 302a extends at the periphery of the upper surface 300. In other words, the outer contour surface 302a is tangent to the edge of the upper surface 300. The outer contour surface 302a is visible to the user when the lid 3 closes the opening 202.

[0069] The inner contour surface 302b defines the periphery of the cavity 303. The inner contour surface 302b extends within the inner part of the lid 3. Therefore, the inner contour surface 302b is not visible to the user when the lid 3 closes the opening 202.

[0070] The inner contour surface 302b has a rounded corner whose shape is complementary to the rounded corner of the neck 201.

[0071] The lid 3 includes at least one second assembly member 304, and the shape of this at least one second assembly member is complementary to the first assembly member 205 of the neck 201. In the illustrated example, the lid 3 includes four second assembly members 304. Each second assembly member 304 of the lid 3 corresponds to one first assembly member 205 of the neck 201, and this second assembly member is configured to cooperate with the corresponding first assembly member.

[0072] In the illustrated example, four second assembly members 304 are formed at the positions of the rounded corners of the contour wall surface 302.

[0073] Of course, the number and position of the second assembly members can vary.

[0074] Since the second assembly members 304 are all the same here, only one of these second assembly members is described, but of course it applies to all other second assembly members.

[0075] The second assembly member 304 is formed in the profile wall surface 302. The second assembly member 304 extends in the inner part of the lid 3 so as to be invisible to the user when the lid closes the opening 202. This enables the improvement of the aesthetics of the bottle or jar 1.

[0076] The second assembly member 304 herein includes a projection or lug 305 and a recess 306. The lug 305 and the recess 306 are adjacent to each other. The shape of the lug 305 is complementary to the notch 207 formed in the neck 201. The recess 306 also has a shape complementary to the protrusion 208. The lug 305 of the second assembly member 304 is configured to be inserted into the notch 207 of the first assembly member 205 between the stopper 206 and the protrusion 208. The recess 306 of the second assembly member 304 is configured to receive the protrusion 208 of the first assembly member 205.

[0077] Herein, the height of the second assembly member 304 is at most equal to the height of the first assembly member 205 of the neck 201. Preferably, the height of the second assembly member 304 is less than or significantly less than the height of the first assembly member 205 of the neck 201.

[0078] Height means the vertical dimension. The height of the neck 201 corresponds to the sum of the height of the edge 204 and the height of the first assembly member 205 intercepted on the same vertical plane.

[0079] In the illustrated example, the heights of the edge and the first assembly member are different at each position. The neck 201 has at least one inclined surface or slope, which is formed at the boundary between the edge 204 and the first assembly member 205. The inclined surface is formed in each part of the neck 201 herein.

[0080] Advantageously, the second assembly member 304 is formed of an elastic material. For example, the flexibility of the material constituting the lid 3 (generally made of a plastic material) can be utilized for the second assembly member. This enables the simple assembly of the first assembly member 205 and the second assembly member 304 together by insertion.

[0081] In Figure 6 In the illustrated exemplary embodiment, the second assembly member includes a cut 307, which is formed in the profile wall surface 302. The cut imparts more flexibility to the second assembly member 304, and thus it is more easily assembled with the first assembly member 205 by insertion.

[0082] According to an embodiment, the lid 3 can be entirely made of an elastic material. The lid 3 can be produced by molding or injection molding so that the lid has a desired shape.

[0083] Generally, at least one of the first assembly member and the second assembly member has flexibility and elasticity such that the assembly members can be assembled together by insertion.

[0084] The shape and dimensions of the inner contour surface 302b are such that the inner contour surface can surround the neck 201 to close the opening 202. In other words, the cross-section of the cavity 303 is at least as large as the cross-section of the neck 201 such that the lid 3 can surround the neck 201 of the base 2 and rotate about the neck.

[0085] The lid 3 is configured to adopt an open position and a closed position in which the lid 3 closes the opening 202. When the lid 3 is in the open position and the closed position, the contour wall surface 302, in particular the inner contour surface 302b, surrounds the neck 201.

[0086] The open position of the lid 3 corresponds to the position where the second assembly member 304 disengages from the first assembly member 205 and the edge 204 of the neck 201. In this position, the lid can rotate freely and be removed vertically relative to the neck 201. The closed position of the lid 3 corresponds to the position where the second assembly member 304 is disposed below the edge 204 of the neck 201. In this position, the rotation of the lid is prevented due to the cooperation of these assembly members (unless sufficient force is applied to the lid to overcome the resistance generated by the insertion assembly of these assembly members), and the vertical removal of the lid 3 relative to the neck 201 is prevented due to the interaction between the first assembly member and the rim 204 as detailed below.

[0087] Figure 7 The lid 3 positioned around the neck 201 and in the open position is shown. Figure 8 and Figure 9 The lid positioned around the neck 201 and in the closed position is shown.

[0088] Advantageously, the cross-section of the cavity 303 corresponds to the superimposed cross-section of the cross-section of the neck 201 in the first position and the cross-section of the neck 201 in the second position, the second position being rotated by a predetermined angle relative to the first position. In other words, the cross-section of the cavity 303 corresponds to the superimposition of the cross-section of the neck 201 and the image obtained by rotating the neck by a predetermined angle about the center (or centroid) of the cross-section.

[0089] The predetermined angle constitutes the angle swept by the lid 3 when the lid moves from the extreme open position to the closed position or vice versa.

[0090] The predetermined angle can be less than 45°. In a preferred embodiment, the predetermined angle is about 22°.

[0091] Thus, when the cap 3 includes the same number of second assembly members 304 as the number of first assembly members 205 of the neck 201, a cavity 303 is formed.

[0092] In another embodiment, the cap 3 may include a number of second assembly members 304 that is less than the number of first assembly members 205 of the neck 201. In an example of a neck 201 having a generally square cross-section and having four first assembly members 205, the cap 3 may include a single, two, or three second assembly members 304.

[0093] Of course, the opposite situation is perfectly conceivable. The cap 3 may include a number of second assembly members 304 that is greater than the number of first assembly members 205 of the neck 201.

[0094] In any case, the cross-section of the cavity 303 is such that the cap 3 can surround the neck 201 when the cap 3 closes the opening 202, particularly when in the open and closed positions. Furthermore, the cross-section of the cavity 303 is such that when the cap 3 is in the open position, the cap 3 can be removed vertically from the neck 201 and rotated about the neck 201, and when the cap 3 is in the closed position, it creates a resistance to rotation of the cap 3 relative to the neck 201 and prevents the vertical removal of the cap 3 relative to the neck 201.

[0095] When the user wishes to close the bottle or can 1, he positions the cap 3 in the open position as Figure 7 shown. In this position, the cap 3 is rotated through a predetermined angle relative to the neck 201. The rounded corners of the cap 3 are then opposite the rounded corners of the neck 201.

[0096] To close the bottle or can 1, the user rotates the cap 3 clockwise, for example. The cap 3 rotates about the neck 201 until the first assembly members 205 of the neck 201 and the second assembly members 304 of the cap 3 are in engagement with each other. In other words, the cap 3 rotates about the neck 201 until the second assembly members 304 bear against the stops 206 of the neck 201. The stops 206 thus form a rotational stop for the cap 3. In the example described, when the cap 3 is in the closed position, the lugs 305 are inserted into the notches 207 of the neck 201, and the protrusions 208 are inserted into the recesses 305. In this position, the second assembly members 304 extend beneath the rim 204. The cap 3 is then vertically blocked by the rim 204. In other words, the cap 3 cannot be removed vertically relative to the neck 201.

[0097] To open the bottle or can 1, the user rotates the cap 3 in a direction opposite to the direction along which it is closed (e.g., counterclockwise). The user overcomes the resistance generated due to the fit between the first assembly member and the second assembly member. The second assembly member 304 of the cap disengages from the first assembly member 204 of the neck 201. The second assembly member 304 of the cap 3 then disengages from the stop 206 of the neck 201. The lug 305 disengages from the notch 207. The protrusion 208 also disengages from the recess 205. The cap 3 can then rotate freely again relative to the base 2. The second assembly member 304 of the cap 3 also disengages from the edge 204 of the neck 201. The cap 3 can then be removed vertically relative to the neck 201 since the cap is no longer blocked by the bead 204.

[0098] Of course, the present invention is not limited to the embodiments described and shown.

[0099] The present invention enables a form of manipulation for screwing onto a neck to be maintained, which neck would not have been expected to allow such a form of manipulation due to its geometry (such as square, another form of polygon, more generally many non-circular forms).

[0100] Such a cap 3 can easily be adapted to any base 2 configured to contain cosmetics and including a neck 201 having at least one first assembly member 205 and an edge 204. Modifying only the cap 3 enables the bottle or can to be opened and closed by a simple and intuitive form of manipulation.
