Description

[0001] This application claims the rights and priority of EP21305303.6, filed on March 12, 2021. Technical Field

[0002] This disclosure relates to a refillable stick for a cosmetic applicator and a cosmetic applicator including the refillable stick and a base for receiving the refillable stick. Background Technology

[0003] A cosmetic applicator is used to apply cosmetic products or materials to a part of the body. Lipstick is an example of a cosmetic applicator. Lipstick includes cosmetic products or materials that provide color, texture, and / or protection to the lips. The cosmetic material of lipstick may be in the form of a stick or rod. Other examples of cosmetic applicator devices include sticks that can be applied to the cheeks, face, or eyes.

[0004] A lipstick may consist of a base and a lipstick holder that surrounds and holds the cosmetic material. The base and lipstick holder are typically rotatably connected. Rotation of the base relative to the lipstick holder causes the cosmetic material to move up and / or down. Once the cosmetic material is used up, a new lipstick may need to be purchased. It is advisable to purchase a brand new lipstick with both the base and the lipstick holder, although some parts of the used lipstick may still be usable.

[0005] Refillable or reusable lipstick cases can reduce waste of lipstick packaging materials. In these cases, several refillable or reusable lipstick cases can be removably attached to a base. In this way, once the cosmetic material is used up, only the refillable lipstick case needs to be purchased. Purchasing a refillable lipstick case is often cheaper than purchasing the entire lipstick. Using refillable lipstick cases also allows for the use of several cosmetic materials in different colors within a single base.

[0006] A refillable lipstick case containing cosmetic material can be removably attached to a base to create a refillable lipstick. Once the cosmetic material in the refillable lipstick is used up, the refillable lipstick case can be removed from the base, and a new refillable lipstick case with new cosmetic material can be removably attached to the base.

[0007] However, users may encounter problems when attaching the refillable lipstick case to the base. During insertion, the user may unintentionally deteriorate the case and / or the base. For example, if the refillable lipstick case is misaligned, it may become stuck inside the base. If the user attempts to move the case relative to the base to unblock it, it may come into contact with components of the base.

[0008] Furthermore, users may inadvertently insert the refillable lipstick case backwards or in the opposite orientation, i.e., with the cosmetic material facing the base. The cosmetic material of the refillable lipstick may thus come into unintentional contact with the base. This could damage the cosmetic material and render the refillable lipstick case unusable.

[0009] This disclosure provides examples of apparatuses that at least partially address some of the aforementioned drawbacks. Summary of the Invention

[0010] In a first aspect, a cosmetic applicator device is provided. The cosmetic applicator device includes a refillable stick container and a base for receiving the refillable stick container.

[0011] The refillable rod box is configured to be removably attached to a base. The refillable rod box extends along a first longitudinal direction and the base extends along a second longitudinal direction. When the refillable rod is attached to the base, the first longitudinal direction is parallel to the second longitudinal direction.

[0012] The refillable stick holder includes a stick holder for holding a stick of cosmetic material and a tubular guide surrounding the stick holder. The tubular guide extends along a first longitudinal direction between a connecting end and an open end of the tubular guide. Furthermore, the tubular guide includes a main portion having a major outer diameter and a connecting portion extending longitudinally from the main portion to the connecting end of the tubular guide. The connecting portion includes an outer surface defining the outer diameter of the connecting portion, wherein the outer diameter of the main portion is larger than the outer diameter of the connecting portion at the connecting end of the tubular guide. Additionally, the stick holder is configured to move within the tubular guide in the first longitudinal direction.

[0013] The base includes an internal member having a transverse wall extending in a direction perpendicular to a second longitudinal direction. The internal member includes a guide protrusion. The guide protrusion projects from a proximal end to a distal end of the protrusion at the transverse wall in a direction substantially parallel to the second longitudinal direction. The guide protrusion is further configured to guide the outer surface of the connecting portion of a tubular guide during insertion of the refillable cassette into the base.

[0014] In this disclosure, a refillable stick should be understood as a stick comprising a base and a holder that encloses cosmetic material attached to the base for use with different cosmetic materials in the base. The cosmetic material can be applied to, for example, the lips, face, cheeks, or eyes. A refillable stick suitable for holding cosmetic material to be applied to the lips can be referred to as a refillable lipstick. Therefore, a refillable lipstick is an example of a refillable stick.

[0015] In this disclosure, the refillable bar box should be understood as a component of the refillable bar, which is configured to be coupled to the base to form the refillable bar.

[0016] The guide protrusions of the internal components of the base and the connection portion of the tubular guide allow for effective guidance of the refillable stick during insertion into the base. Because the outer diameter of the main portion is larger than the outer diameter of the connection portion at the connection end of the tubular guide, the guidance of the refillable stick is enhanced. The refillable stick can therefore be easily inserted into the base. This reduces the risk of accidental damage to components of the cosmetic applicator device.

[0017] Furthermore, since the outer diameter of the main part is larger than that of the connecting part, the guide protrusion prevents the refillable stick from being inserted backward, for example, by inserting the main part of the tubular guide first instead of the connecting part. The guide protrusion can prevent the insertion of the refillable stick by contacting the main part of the tubular guide. The specific shape of the tubular guide and internal components constitutes a mistake-proofing system. A mistake-proofing system is a system to prevent incorrect operation by the user. In this case, the cosmetic applicator device prevents incorrect insertion of the refillable stick. This prevents the cosmetic material from accidentally coming into contact with a part of the base. Therefore, the risk of damaging the cosmetic material can be reduced.

[0018] In some examples, the connecting portion of the tubular guide includes a tapered region. The outer diameter of the connecting portion decreases toward the connecting end of the tubular guide. This improves the smooth guidance of the refillable cassette. The tubular guide may include a main portion having a substantially constant outer diameter and a tapered region disposed at the connecting end of the tubular guide. The truncated conical or tapered region may extend from the main portion toward the connecting end of the tubular guide (e.g., the end of the inner member of the tubular guide facing the base). In the tapered region, the outer diameter of the connecting portion gradually decreases from a first diameter to a second diameter, where the first diameter is larger than the second diameter. Therefore, the outer diameter of the connecting portion gradually decreases toward the connecting end of the tubular guide in the tapered region. The outer surface of the connecting portion can be substantially smooth. This reduces frictional forces on the guide protrusion.

[0019] In some examples, the outer diameter of the connecting portion at the tapered region decreases continuously from the outer diameter of the main portion to the outer diameter of the connecting portion at the connecting end of the tubular guide. Alternatively, the connecting portion of the tubular guide includes a lower straight region, wherein the tapered region lies between the main portion and the lower straight region.

[0020] The guide protrusion may include a shape complementary to the connecting portion, such as a shape complementary to the tapered region of the tubular guide. The connecting portion can therefore easily engage the guide protrusion. Thus, during insertion, the refillable cassette can be easily guided. Furthermore, this complementary shape can help maintain the tubular guide in the desired position when it is connected to the internal components. In these examples, because the guide protrusion includes a shape complementary to the connecting portion, the guide protrusion includes a tapered region. For example, the guide protrusion may include a straight portion and a tapered portion.

[0021] In some examples, the guide protrusion includes a wedge-shaped cross-section to substantially engage a tapered region of the coupling area of ​​the tubular guide. The inner surface of this wedge-shaped cross-section may face the outer surface of the coupling portion at the tapered portion. The guide protrusion may therefore include a tapered portion extending from the proximal end of the protrusion to the distal end of the protrusion.

[0022] In some examples, the guide protrusion is annular. Alternatively, the guide protrusion may comprise multiple annular segments. A gap may be defined between two consecutive annular segments. In these examples, the inner surfaces of these annular segments are configured to engage the outer tube. Therefore, the shape of these annular segments is complementary to the guide portion. For example, the annular segments may comprise a wedge-shaped cross-section.

[0023] The annular segment can extend the circumference by a predetermined angle. Using an annular segment instead of an annular guide protrusion (extending 360°) simplifies the manufacturing process because it improves the injection or molding process while maintaining the guidance of the tubular guide. In some examples, the annular segment can extend between 0.5° and 45° of the circumference. In some examples, the annular segment extends between 0.5° and 5° of the circumference. The guide protrusion can include multiple annular segments, for example, between 3 and 10, particularly between 3 and 8.

[0024] In one example, the guide protrusion comprises four annular segments, each extending approximately 2° of the circumference. In this example, an 88° circumferential gap is defined between two consecutive annular segments.

[0025] The guide protrusion may include an inner diameter. This inner diameter may be defined by the inner surface of a wedge-shaped cross-section. The inner surface of the wedge-shaped cross-section may be inclined relative to a second longitudinal direction. In this way, the inner diameter of the guide protrusion increases from the transverse wall. The inner diameter of the guide protrusion at its proximal end may be larger than that at its distal end. The inner surface of the wedge-shaped cross-section can therefore substantially conform to the tapered region of the tubular guide.

[0026] In some examples, the outer surface of the connecting portion at the tapered section of the tubular guide forms an angle between 1° and 10° with the first longitudinal direction. In some examples, this angle can be between 4° and 8°. These angles can improve the manufacturing process. For example, for tubular guides made of plastic, these angles allow for easy removal from the injection molding tool.

[0027] In some of these examples, the inner surface of the guide protrusion may form an angle between 1° and 10° with the second longitudinal direction. In some examples, this angle may be between 4° and 8°. In this way, the inner surface of the guide protrusion matches the outer surface of the connecting portion. The inner surface of the guide protrusion can therefore be substantially parallel to the outer surface of the connecting portion at the tapered region.

[0028] In some examples, the outer diameter of the main portion of the tubular guide is 0.5–1.5 mm larger than the outer diameter of the connecting portion at the connecting end of the tubular guide. This diameter difference allows the guide protrusion to easily guide the tubular guide toward the internal component. Furthermore, this diameter difference between the outer diameter of the main portion and the outer diameter of the connecting portion at the connecting end of the tubular guide improves the holding force of the tubular tube within the internal component. In other examples, the outer diameter of the main portion of the tubular guide is approximately 0.9 mm larger than the outer diameter of the connecting portion at the connecting end of the tubular guide.

[0029] In some examples, the refillable rod box includes a tubular housing surrounding a tubular guide. The tubular housing extends from a first end to a second end. The tubular housing may extend its height between the first and second ends. The tubular guide extends its height between its connecting end and its open end. The height of the tubular housing may be greater than the height of the tubular guide. The height of the tubular housing may be 3 to 5 millimeters greater than the height of the tubular guide, for example, about 4 millimeters.

[0030] In some examples, the first end of the tubular housing and the connecting end of the tubular guide are substantially in the same plane. The connecting end of the tubular guide can therefore be surrounded or covered by the first end of the tubular housing. The connecting end of the tubular guide can thus be protected by the tubular housing.

[0031] In some examples, a cavity is formed between the tubular housing and the connecting portion at the first end of the tubular housing. The tubular housing may include an inner surface defining the inner diameter of the tubular housing. The inner diameter of the tubular housing may be substantially constant along the height of the tubular housing. In some examples, for example, when the connecting portion includes a tapered portion, the cavity is annular and includes a substantially wedge-shaped cross-section.

[0032] The guide protrusion can be received by a cavity formed between the tubular housing and the tubular guide. The guide protrusion can therefore be surrounded between the outer surface of the connecting portion and the outer surface of the tubular housing. The refillable stick can thus be precisely guided toward the base. Furthermore, the fixation of the refillable stick to the base can be improved. Therefore, the stick of cosmetic material held by the stick holder can move precisely inside the tubular guide.

[0033] In some examples, the connecting portion of the tubular guide includes a connecting bracket, and the internal component includes a connector configured to be removably coupled to the connecting bracket of the tubular guide. The refillable rod box can therefore be removably coupled to the base via the connection between the connecting bracket and the connector.

[0034] In some examples, the tubular housing includes an edge at a second end of the tubular housing. The edge extends radially inward from the inner surface of the tubular housing. The edge may cover at least a portion of the open end of the tubular guide. Thus, the edge extends radially from the inner surface of the tubular housing toward the tubular guide. The radial direction is substantially perpendicular to the first longitudinal direction. In some examples, the wall of the tubular guide defined between the inner surface tubular guide and the outer surface tubular guide may be covered by the edge. The edge thus protects the tubular guide.

[0035] If the refillable stick is intended to be inserted into the base in the opposite orientation (i.e., the open end of the tubular guide faces the face), then the guide protrusion contacts the edge to prevent full insertion. The guide protrusion can therefore be configured to contact the edge of the tubular housing during insertion of the refillable stick into the base when the open end of the tubular guide faces the base. Insertion of the refillable stick in the opposite orientation can thus be prevented by the guide protrusion. This prevents the stick of cosmetic material from being accidentally contacted by internal components (e.g., connectors of internal components). Therefore, the risk of damage to the stick-shaped cosmetic material can be reduced.

[0036] In another aspect, a refillable stick holder for a cosmetic applicator device is provided. The refillable stick holder can be any of the examples disclosed herein. The refillable stick holder is configured to be removably coupled to the base of the cosmetic applicator device. The refillable stick holder and the base can thus form a cosmetic applicator device, such as a refillable stick, according to any of the examples disclosed herein. In some examples, the refillable stick holder can be a refillable lipstick holder.

[0037] A refillable stick container extends along a first longitudinal direction and includes a stick holder for holding a stick of cosmetic material and a tubular guide surrounding the stick holder. The tubular guide extends along the first longitudinal direction between a connecting end of the tubular guide and an open end of the tubular guide. The stick holder is configured to move within the tubular guide in the first longitudinal direction.

[0038] Furthermore, the tubular guide includes a main portion having a major outer diameter and a connecting portion extending longitudinally from the main portion to a connecting end of the tubular guide. The connecting portion may include a tapered portion including an outer surface of the connecting portion defining the outer diameter of the connecting portion. In this example, the outer diameter of the connecting portion decreases toward the connecting end of the tubular guide, such that the outer diameter of the main portion is larger than the outer diameter of the connecting portion at the connecting end of the tubular guide.

[0039] The advantages arising from this second aspect are similar to those mentioned regarding the cosmetic applicator device in the first aspect. That is, the refillable stick can be easily guided during insertion into the base. Furthermore, incorrect insertion is prevented, for example, when the refillable stick is intended to be inserted in the opposite orientation.

[0040] In another aspect, a kit is provided that includes a base and a plurality of refillable stick cartridges configured to be removable from the base. Thus, a user can removably attach one of the refillable stick cartridges to the base to apply a specific stick of cosmetic material. For example, each refillable stick cartridge may include sticks of different colors. The user can therefore use a single base to apply different colors. The base of this kit can be any of the examples disclosed herein. The plurality of refillable stick cartridges can be any of the examples disclosed herein. Attached Figure Description

[0053] In these figures, the same reference numerals have been used to denote matching elements.

[0054] Figure 1 An example of a cosmetic applicator device 10 including a refillable stick cassette 100 and a base 20 is shown. The refillable stick cassette 100 can be inserted and removably coupled to the base 20. The base 20 includes an open end 21 and a cavity 22 for receiving the refillable stick cassette 100. The refillable stick cassette 100 includes a cavity 102 for containing a stick of cosmetic material (not shown in this figure) and an open end 101 that allows a portion of the stick of cosmetic material to protrude from the interior of the refillable stick cassette. A user can couple the refillable stick cassette 100 to the base 20. The user can then move the stick of cosmetic material in the refillable stick cassette along the cavity 102 to apply the cosmetic material to the lips.

[0055] The refillable rod box 100 extends along a first longitudinal direction 11 and the base extends along a second longitudinal direction 12. When the refillable rod box 100 is attached to the base 20, the first longitudinal direction 11 is parallel to the second longitudinal direction 12.

[0056] Figure 2a A cross-sectional view of a cosmetic applicator device 10 having a refillable stick cassette 100 and a base 20 is shown. Figure 2b An enlarged view of the connection between the refillable stick box 100 and the base 20. The refillable stick box 100 is removably connected to the base 20.

[0057] The refillable stick cassette 100 includes a stick holder 110 for holding a stick 111 of cosmetic material. In this example, the stick of cosmetic material is a lipstick, configured to be applied to the lips. The stick holder 110 is movable within a tubular guide 120 for removing a portion of the stick of cosmetic material from the refillable stick cassette 100. The tubular guide 120 extends along a first longitudinal direction 11 between a tubular guide connecting portion 140 and a tubular guide open end 122.

[0058] The tubular guide 120 includes a main portion 130 and a connecting portion 140. Figure 2a In this configuration, the main portion 130 corresponds to the upper part of the tubular guide, and the connecting portion 140 corresponds to the lower part of the tubular guide. The main portion 130 extends from the open end 122 of the tubular guide to the connecting portion 140. The connecting portion 140 extends from the main portion 130 to the connecting end 121 of the tubular guide.

[0059] The connecting portion 140 includes a connecting bracket 150 and a connecting portion outer surface 141 that defines the outer diameter of the connecting portion. The outer diameter of the main portion is larger than the outer diameter of the connecting portion.

[0060] In this example, the connecting portion 140 includes a tapered region 160 that decreases the outer diameter of the connecting portion toward the tubular guide connecting end 121. The outer surface 141 of the connecting portion in these figures forms an angle between 1° and 10° with the first longitudinal direction 11.

[0061] The base 20 includes an internal member 30 having a transverse wall 31 extending in a direction perpendicular to the second longitudinal direction 12. In this example, the internal member 30 includes a connector 40 and a guide protrusion 50. In these figures, the connector 40 is coupled to a coupling bracket 150 of the tubular guide 120.

[0062] The guide protrusion 50 extends from the proximal end of the protrusion at the transverse wall 31 in a direction substantially parallel to the second longitudinal direction 12. In these figures, when the refillable cassette 100 is attached to the base 20, the inner surface 53 of the guide protrusion engages with the outer surface 141 of the connecting portion.

[0063] The guide protrusion 50 in these figures includes a substantially wedge-shaped cross-section. In these figures, the guide protrusion 50 has an annular shape. The wedge-shaped cross-section thus extends along the entire circumference. In other examples, multiple annular segments may include substantially wedge-shaped cross-sections. The inner surface 53 of the guide protrusion defines the inner diameter of the guide protrusion. In these figures, this inner diameter of the guide protrusion increases from the transverse wall 31 to the opening end 21 of the base 20.

[0064] The shape of the inner surface 53 of the guide protrusion in these figures is complementary to the shape of the outer surface 141 of the connecting portion. In this example, the inner surface 53 of the guide protrusion substantially matches the outer surface 141 of the connecting portion.

[0065] The internal component 30 in these figures includes an inverted cap shape having a sidewall 32 extending from the transverse wall 31 in a direction parallel to the second longitudinal direction. The sidewall 32 is substantially perpendicular to the transverse wall 31. The sidewall 32 defines an internal cavity.

[0066] In this example, the base 20 further includes a support element 80 that engages with the internal member. The support element 80 includes a cylindrical body 81 inserted into a cavity defined by the sidewall 32 of the internal member 30. In this example, the support element 80 further includes a flange 82 extending radially outward from the cylindrical body 81. The flange 82 can support the sidewall 32 of the internal member 30.

[0067] In some examples, the internal member 30 includes a plurality of supports for engaging a sleeve arranged around the internal member 30. The supports may be arranged at the sidewall 32. The plurality of supports may form a ring gear. The supports may be distributed along the outer periphery of the sidewall 32 and may extend outward from the outer surface of the sidewall 32. The sleeve may include a plurality of supports engaging the supports of the internal member 30. Rotation of the sleeve can cause rotation of the internal member 30. When the refillable rod box 100 is coupled to the base 20, for example when the connecting bracket 150 of the tubular guide 120 is coupled to the connector 40 of the internal member 30, rotation of the internal member 30 causes rotation of the tubular guide 120. Rotation of the tubular guide 120 causes movement of the rod holder 110 in a first longitudinal direction 11.

[0068] In this example, the refillable rod box 100 includes a tubular housing 170 surrounding a tubular guide 120. The tubular housing 170 extends from a first end to a second end. The first end of the tubular housing is near the connecting end 121 of the tubular guide, and the second end is near the opening end 122 of the tubular guide. In these figures, the tubular housing 170 covers the tapered region 160 of the connecting portion 140. This enhances protection of the connecting portion.

[0069] As can be seen in these figures, the guide protrusion 50 is surrounded between the outer surface 141 of the connecting portion and the inner surface 171 of the tubular housing. When the tubular guide is attached to the internal component, as shown in these figures, the outer surface 141 of the connecting portion can contact the inner surface 53 of the guide protrusion. However, a gap is defined between the inner surface 171 of the tubular housing and the outer surface 54 of the guide protrusion. This gap allows the internal component 30 and the tubular guide 120 to rotate relative to the tubular housing.

[0070] Figure 2aThe tubular housing 170 includes a edge 173 disposed at a second end of the tubular housing. In this example, the edge 173 extends inwardly from the inner surface 171 of the tubular housing in a radial direction (i.e., perpendicular to the first longitudinal direction 11). The edge 173 in this figure covers at least a portion of the opening end 122 of the tubular guide. The edge 173 may define... Figure 2a The outermost surface of the refillable rod box.

[0071] In this example, the tubular guide 120 and the internal component 30 are made of plastic. This reduces the manufacturing cost of the cosmetic applicator. The tubular housing can be made of aluminum. This increases the durability and aesthetics of the refillable stick container. The base may include an outer cover. This cover can be made of aluminum to increase the overall durability of the cosmetic applicator device and for aesthetic reasons.

[0072] Figure 3a A perspective view of the connecting portion 140 of a tubular guide for a refillable rod box according to an example of this disclosure is shown. Figure 3b for Figure 3a A cross-sectional view of the connecting portion 140 of the tubular guide.

[0073] The connecting portion 140 of these figures includes a tapered region 160 surrounded by a tubular housing 170. The tapered region 160 includes an outer surface 141 of the connecting portion facing the inner surface 171 of the tubular housing. An annular cavity 175 is formed between the tubular housing 170 and the tapered region 160. The annular cavity 175 is defined between the outer surface 141 of the connecting portion and the inner surface 171 of the tubular housing. A guide protrusion of the base may be received in the cavity 175.

[0074] The tubular guide 120 in these figures includes an annular lip 125 extending outward from the outer surface of the tubular guide. The annular lip 125 can be flexible to adjust the position of the tubular housing 170 relative to the tubular guide 120. In some examples, the distal end of the annular lip contacts the inner surface 171 of the tubular housing. The annular lip 125 can thus close one side of the cavity 175. The annular cavity can thus be defined between the outer surface 141 of the connecting portion, the annular lip 125, and the inner surface 171 of the tubular housing. The annular lip can facilitate precise adjustment of the relative position between the guide protrusion of the internal component and the connecting portion 140 of the tubular guide.

[0075] In these figures, the annular lip 125 extends from the transition region between the outer surface 131 of the main portion and the outer surface 141 of the connecting portion. The annular lip 125 thus separates the annular cavity 175 from the gap 176 defined between the outer surface 131 of the main portion and the inner surface 171 of the tubular housing. A helical tube (not shown in these figures) can be arranged in the gap 176.

[0076] In these figures, the connecting portion includes a connecting bracket 150. The connecting bracket 150 includes a connecting tube 151 that extends the connecting tube height from the connecting end 121 of the tubular guide toward the open end of the tubular guide in a direction parallel to the first longitudinal direction 11. The connecting bracket 150 further includes a wall 152 extending radially from the outer surface 141 of the connecting portion to the connecting tube 151. In these figures, the wall 152 is substantially perpendicular to the first longitudinal direction 11. The wall 152 covers the inner cavity of the tubular guide. The connecting tube 151 is used for a connector removably coupled to an internal component of the base. For example, multiple snap-fit ​​elements of the base's connector can engage the connecting tube 151 to secure a refillable cassette to the base.

[0077] The connecting tube 151 in these figures includes an inner surface 153 facing the connector outer surface of the base. In this example, the inner surface 153 includes a plurality of protrusions 154. When the refillable cassette is attached to the base, the connector of the base can be surrounded by the connecting tube 151. The plurality of protrusions 154 engage the connector of the base to prevent undesirable rotation of the connecting tube of the refillable cassette around the internal components of the base.

[0078] Figure 4a A perspective view of the internal components 30 of a base according to an example of this disclosure is shown. Figure 4b for Figure 4a Cross-sectional views of the internal component 30. These views show the internal component 30 configured to be connected to a device having... Figure 3a and Figure 3b The example is a tubular guide for the connecting part.

[0079] The internal component 30 in these figures includes an inverted cap shape having a sidewall 32 extending from the transverse wall 31. A guide protrusion 50 protrudes from the transverse wall 31 in a direction parallel to the second longitudinal direction 12. The internal component 30 in these figures includes a connector 40 configured to engage a connecting bracket of a tubular guide. The connector 40 also protrudes from the transverse wall 31 in a direction parallel to the second longitudinal direction 12.

[0080] In this example, connector 40 extends the connector height from transverse wall 31 in a direction parallel to the second direction. Guide protrusion 50 further protrudes the protrusion height from transverse wall 31 in a direction parallel to the second direction. In this example, the protrusion height and connector height are substantially similar. As will be discussed in more detail later, these heights reduce the risk of damaging the cosmetic material rod if the refillable rod is inserted rearward or in the opposite orientation. In other examples, the protrusion height may be greater than the connector height.

[0081] For reference Figure 2a and Figure 2bAs explained, the guide protrusion extends from the proximal end 51 of the protrusion at the transverse wall 31 to the distal end 52 of the protrusion. A connecting portion of the tubular guide of the refillable cassette can be arranged between the inner surface 53 of the guide protrusion and the connector 40. When the refillable cassette is inserted into the base, the outer surface 54 of the guide protrusion can face the tubular housing. The guide protrusion in these figures is annular and includes a wedge-shaped cross-section. However, in other examples, the guide protrusion may include multiple annular segments. These annular segments may include wedge-shaped cross-sections.

[0082] In these figures, the connector 40 of the internal component includes a plurality of snap-fit ​​elements 41 to engage the connecting tube of the connecting bracket of the refillable rod box. The snap-fit ​​elements 41 temporarily connect the connecting tube (and thus the inner surface of the connecting tube) to the internal component. In this example, the plurality of snap-fit ​​elements 41 are oriented outward. Alternatively, the plurality of snap-fit ​​elements may be oriented inward to surround the connecting tube.

[0083] In these figures, ring 42 connects multiple snap-fit ​​elements 41. Ring 42 includes an outer surface 43 to engage the inner surface of the connecting tube. The outer surface 43 includes a protrusion 44. This protrusion can engage between two consecutive protrusions on the inner surface of the connecting tube. This prevents rotation of the tubular guide about the internal components.

[0084] Figure 5 The connection between a refillable stick container and a base of a cosmetic applicator according to an example of this disclosure is schematically illustrated. A tubular guide 120 includes a connecting portion 140 and a main portion 130. A tubular housing 170 surrounds the tubular guide 120. The connecting portion 140 includes a tapered region 160. Furthermore, the connecting portion 140 in this figure includes a lower straight region 252.

[0085] In this figure, the tapered region 160 extends from the main portion 130 to the lower straight region 252. The lower straight region 252 extends from the tapered region 160 to the tubular guide connection end 121. The outer surface 141 of the connection portion defines a decreasing outer diameter of the connection portion at the tapered region 160. The outer diameter of the connection portion is substantially constant at the lower straight region 252.

[0086] The internal component 30 in this figure includes a guide protrusion 50 projecting from the transverse wall 31. In this example, the internal component includes an inverted cap shape having sidewalls 32 extending from the transverse wall 31.

[0087] The outer surface 141 of the connecting portion of the tubular guide 120 includes a plurality of protrusions 251, which are configured to engage a plurality of receivers 250 of the guide protrusions. In this figure, the plurality of protrusions 251 are arranged in the lower straight region 252. The protrusions 251 of the tubular guide mate with the receivers of the inner base. Thus, a connection can be established between the tubular guide and the inner base.

[0088] In this figure, the connecting portion 140 does not include the connecting bracket, for example... Figures 3a-3b The connecting bracket is depicted in the figure. However, in other examples, the connecting portion 140 includes the connecting bracket and a plurality of protrusions 251. In this figure, the internal component 30 does not include a connector, for example... Figures 4a-4b The connector is depicted in the figure. However, in other examples, the internal component 30 includes a connector and a plurality of receivers 250.

[0089] In some examples, multiple protrusions may be arranged on the inner surface of the guide protrusion, and the outer surface of the connecting portion may include multiple receivers to receive the protrusions.

[0090] Figure 6 The diagram schematically illustrates the tapered region 160 of the connecting portion of a tubular guide and the guide protrusion 50 of the internal member 30, according to one example of the present disclosure. In some examples, the connecting portion may also include a connecting bracket, and the internal member may also include a connector.

[0091] The tapered region 160 includes a connecting portion outer surface 141 that defines the outer diameter of the connecting portion. This connecting portion outer diameter of the tapered region 160 decreases towards the tubular guide connecting end 121. In this figure, the main portion outer diameter is indicated by 146, and the connecting portion outer diameter at the tubular guide connecting end 121 is indicated by 145.

[0092] In this figure, the outer diameter of the main part 146 is approximately 14.8 mm. The outer diameter of the connecting part 145 in this figure is approximately 13.9 mm. In this figure, the difference between the outer diameter of the connecting part 145 and the outer diameter of the main part 146 at the connecting end 121 of the tubular guide is approximately 0.9 mm.

[0093] In some examples, the outer diameter 145 of the connecting portion can be between 13.5 mm and 14.3 mm, optionally between 13.8 mm and 14.0 mm. The outer diameter 146 of the main portion can be between 14.4 mm and 15.2 mm, optionally between 14.7 mm and 14.9 mm. In these examples, the outer diameter 146 of the main portion is 0.5-1.5 mm larger than the outer diameter 145 of the connecting portion at the connecting end 121 of the tubular guide, optionally about 0.9 mm.

[0094] In this figure, the tapered region 160 of the tubular guide mates with a cavity defined by the inner surface 53 of the guide protrusion 50 of the internal member 30. The guide protrusion 50 in this figure extends from its proximal end 51 at the transverse wall 31 to its distal end 52. In this figure, the inner surface 53 of the guide protrusion defines an inner diameter that decreases toward the transverse wall 31. In this example, the inner diameter of the guide protrusion substantially corresponds to the outer diameter of the connecting portion.

[0095] The inner diameter of the guide protrusion at the distal end 52 of the protrusion is indicated by 56, and the inner diameter of the guide protrusion at the proximal end 51 of the protrusion is indicated by 55. In this figure, the inner diameter of the guide protrusion 55 is approximately 14.0 mm, and the inner diameter of the guide protrusion 56 is approximately 14.9 mm.

[0096] In some examples, the inner diameter 55 of the guide protrusion can be between 13.6 and 14.4 mm, optionally between 13.9 and 14.1 mm. The inner diameter 56 of the guide protrusion can be between 14.5 and 15.3 mm, optionally between 14.8 and 15.0 mm.

[0097] In this diagram, the inner diameter of the guide protrusion, 55, is equal to or greater than the outer diameter of the connecting portion, 145. The tubular guide can therefore fit and remain within the internal base.

[0098] In this figure, the tapered region 160 extends parallel to the first longitudinal direction 11 with a tapered height 148. The tapered height 148 in this figure is approximately 6 mm. In this example, the tapered height 148 extends from the main portion of the tubular guide to the connecting end 121 of the tubular guide. In some examples, the tapered height 148 may be between 4 and 8 mm, optionally between 5 and 7 mm, for example, approximately 6 mm.

[0099] In this figure, the guide protrusion 50 extends between the proximal end 51 and the distal end 52 of the guide protrusion at the transverse wall 31, with a guide protrusion height 58. The guide protrusion height 58 is similar to the cone height 148. The guide protrusion height 58 can be between 4 and 8 mm, optionally between 5 and 7 mm. In this figure, the guide protrusion height 58 is approximately 6 mm.

[0100] The outer surface 141 of the connecting portion forms an angle 147 with the first longitudinal direction 11. The angle 147 can be between 1° and 10°, and optionally between 4° and 8°. In this example, the angle 147 is approximately 7°.

[0101] The inner surface 53 of the guide protrusion forms an angle 57 with the second longitudinal direction 12. Angle 57 substantially corresponds to angle 147. Angle 57 can be between 1° and 10°, optionally between 4° and 8°. In this example, angle 57 is approximately 7°.

[0102] The shape and size of the guide protrusion 50 and the tapered region 160 allow the tubular guide (and therefore the refillable cassette) to be smoothly inserted into the inner member 30 (and therefore smoothly inserted into the base). The tubular guide can be precisely guided during insertion and is held in the base when the refillable cassette is attached to the base. Furthermore, when the tubular guide and inner member 30 are made of plastic material, these shapes allow for easy removal from the syringe device.

[0103] Figure 7 Show Figure 2a and Figure 2b A cross-sectional view of a cosmetic applicator device, wherein a refillable stick is designed to be inserted into a base in the opposite orientation.

[0104] In this figure, the refillable rod box 100 is intended to be inserted rearward or in the opposite orientation, i.e., with the tubular guide opening end 122 of the tubular guide 120 facing the internal member 30 of the base 20.

[0105] The tubular guide includes a main portion 130 having a main outer diameter and a connecting portion 140 having a connecting outer diameter. The internal member 30 includes a guide protrusion 50 having a guide protrusion inner diameter. In this figure, the main portion 130 is intended to be inserted into the base. However, because the inner diameter of the guide protrusion is smaller than the outer diameter of the main portion, complete insertion of the refillable rod box is prevented.

[0106] The distal end 52 of the guide protrusion prevents the refillable stick cartridge 100 from being inserted into the base. This prevents the cosmetic material stick 111 contained inside the refillable stick cartridge from coming into contact with the connector 40 of the internal component 30. Therefore, it prevents the cosmetic material stick 111 from being damaged.

[0107] The tubular housing 170 surrounding the tubular guide 120 includes an edge 173 disposed at a second end of the tubular housing. The edge 173 of the tubular housing 170 is stopped by the distal end 52 of the guide protrusion. The height of the guide protrusion is equal to or greater than the connector height. The stopping function is further improved. This edge 173 thus enhances the error-proof configuration of the cosmetic applicator device.

[0108] Figure 8 An exploded view of a refillable rod box according to an example of the present disclosure is shown. The refillable rod box 100 includes a tubular guide 120 and a tubular housing 170 according to any of the examples disclosed herein.

[0109] A stick holder 110 for holding a stick (not shown in this figure) of cosmetic material can be arranged inside a tubular guide 120. The stick holder 110 is movable within the tubular guide 120. The stick holder 110 includes a pair of stick holder supports 112. These stick holder supports 112 are guided by a pair of longitudinal grooves 138 arranged at the main portion 130 of the tubular guide 120. Each of the stick holder supports 112 engages a different longitudinal groove 138. The stick holder support can travel within the corresponding longitudinal groove 138.

[0110] A helical tube 190 may be arranged between a tubular guide 120 and a tubular housing 170. The helical tube 190 includes a pair of helical grooves 191 extending along its inner surface. A rod retainer support 112 engages the helical grooves 191.

[0111] In this figure, the tubular housing 170 and the helical tube 190 can rotate together. The tubular guide 120 rotates about the tubular housing 170 and the helical tube 190. The rod holder 110 can move about the tubular guide 120 in a first longitudinal direction.

[0112] The relative rotation of the helical tube 190 about the tubular guide 120 causes the rod retainer 110 to move relative to the tubular guide 120 in the first longitudinal direction. As the rod retainer support 112 disengages through the longitudinal groove 138 and engages the helical groove 191, the rotation of the helical tube forces the rod retainer 110 to move up and down relative to the tubular guide 120.
