[0041] The following description is purely exemplary and is not intended to limit the present disclosure, its application or its uses.

[0042] The following detailed description of the present invention refers to the accompanying drawings, which illustrate specific embodiments in which the present invention may be implemented. These embodiments are described in sufficient detail to enable those skilled in the art to practice the present invention. It should be understood that various embodiments of the present invention are different from one another, but need not be mutually exclusive.

[0043] With respect to the terms used in the present invention, the general terms that are currently and widely used are chosen in consideration of the functions of the present invention. However, the meaning of the terms may be changed according to the intention of those skilled in the art, judicial precedent, the emergence of new technology, and the like. Furthermore, in some cases, a term may be chosen at the discretion of the applicant. In such cases, the meaning of the term will be described in detail in the corresponding part of the description of the invention. Therefore, the terms used in the present invention should be defined based on the meaning of the terms and the complete descriptions provided herein without being limited simply to the names of the terms.

[0044] In the present disclosure, when a certain part "includes" certain elements, unless explicitly stated otherwise, it means that other elements may be included, but not excluded.

[0045] Hereinafter, a refillable cosmetic container with a practical refillable structure according to one or more embodiments of the present invention will be described with reference to Figures. 1 to 8.

[0046] As shown in the drawings, the refillable cosmetic container 100 according to one embodiment of the present invention may include an outer housing 110, an inner container 120, a bottom ring 150, and a discharge unit. In one example, the refillable cosmetic container further comprises a cap capsule assembly. In the following, each component of the cosmetic container according to one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0047] As shown in [Fig.l], the outer housing 110 may be configured as a rigid cylinder and is provided with one side (i.e., the top side of the [Fig. 1 ]) of the dispensing unit and is provided on another side (i.e., the low side in [Fig.l]) with an inner container 120. As shown in [Fig.l], the discharge unit has a pressure bar 170, and the pressure bar 170 has a nozzle 171 (as shown in Figure 3) for dispensing the cosmetics. The outer housing 110 is also provided on another side (i.e., the low side in [Fig.l]) with the bottom ring 150.

[0048] [Fig. 2] is an exploded perspective view showing the refillable cosmetic container 100 according to one embodiment of the present invention. In one example, the refillable cosmetic container 100 comprises an outer housing 110, an inner container 120, a cap capsule assembly 130, 140, a bottom ring 150, a bottom cover 160, and a discharge unit. In one example, the discharge unit comprises a pressure bar 170, a compression spring 192, a hollow shaft 180, a pump piston 190, a ball 191, and a pump body 112. However, such a configuration of the dispensing unit is only an example, and therefore the dispensing unit may be freely configured, without being limited thereto. The pump body 112 is part of the outer housing 110 and extends axially from a horizontal plate 111 of the outer housing 110.The hollow shaft 180 is installed on the vertical internal passage of the pressure bar 170, and the pump piston 190 moves axially or vertically in the cavity of the pump body 112. In addition, the hollow shaft 180, the pump piston 190, the ball 191 and the pump body 112 may constitute a pump or a pumping assembly for pumping the cosmetics from the inner container 120.

[0049] In one example of the present application, the discharge unit is coupled to an upper portion of the outer housing 110, so as to discharge the cosmetic products outwardly by the pumping action of the pumping assembly in accordance with the lifting / lowering of the pressure bar 170 relative to the outer housing 110.

[0050] [Fig.7] is a bottom perspective view showing the internal structure of an outer housing 110 of the refillable cosmetic container 100 according to an embodiment of the present invention, wherein a cap bar 114 of the outer housing 110 is shown in close-up view. The outer housing 110 has a horizontal plate 111 near its upper end. As shown in [Fig. 2], the outer housing 110 further comprises a pump body 112 extending axially upward from the horizontal plate 111. In addition, as shown more clearly in [Fig. 7], the outer housing 110 further comprises a guide collar 113 extending axially downward from the horizontal plate 111 and a plug bar 114 also extending axially downward from the horizontal plate 111. The plug bar 114 is coaxial with the guide collar 113 and has a smaller radius than that of the guide collar 113. As shown in Figures 3a and 7, the cap bar 114 has a vertical passage 1144 passing through the horizontal plate 111 so as to allow the passage of cosmetics.

[0051] In one example, the guide collar 113 includes one or more vertical guide mechanisms, such as vertical guide ribs 1131 for guiding the inner container 120, as will be explained below. In one example, the cap bar 114 includes one or more push bars 1141 for pushing the connecting cap assembly downward, as will be explained below. In other words, there will be one or more notches 1142 circumferentially located between the push bars 1141. In one example, near the push bars 1141, the plug bar 114 has a hopper portion 1143 for receiving the ball 190. The diameter of the ball 190 is larger than the smallest diameter of the vertical passage 1144 that passes through the hopper portion 1143. The bottom end of the push bar 1141 is lower than the bottom end of the hopper portion 1143.With such an arrangement of the cap bar 114, the cosmetic products can flow through the outer housing 110 so as to be discharged once the refillable cosmetic container 100 is installed in position.

[0052] [Fig. 6] is a perspective view showing the inner container 120 of the refillable cosmetic container 100 according to one embodiment of the present invention. After installation, the outer housing 120 accommodates the inner container 110 therein. The inner container 110 comprises a receiving member 121 and a neck 122. The bottom of the inner container 110 is engaged by a bottom cover 160, as will be explained below.

[0053] The receiving member 121 provides a storage space for the contents. As shown, the receiving member 121 has a long cylindrical shape, but is not limited to it. In this case, the contents are a fluid of liquid or gel, which includes a cosmetic, a drug, and a quasi-medicated dental paste, but these are merely examples, so the contents may include all kinds of materials capable of being discharged by pumping. A piston 124 may be provided within the receiving member 121 so as to seal the contents or cosmetics within the storage volume or space enclosed by the piston 124 and the receiving member 121. As the contents or cosmetics are consumed, the piston 124 automatically moves upward to keep the storage space free of air.

[0054] The neck 122 of the inner container 110 has one or more axial extension ribs 1221 on their outer peripheral surface and a step portion 1222 on their inner peripheral surface. The axial extension rib is an example of an axial extension guide mechanism. When installing the refillable cosmetic container 100, the axial extension ribs 1221 and the guide ribs 1131 will cooperate together to vertically guide the inner container 120 to insert it into the outer housing 110 from the bottom thereof. As one skilled in the art would readily understand, there are many other types of guide mechanisms for guiding the inner container 120 relative to the outer housing 110. Near the lower end periphery of the receiving member 121, there are external threads 123 on the outer peripheral surface of the receiving member 121.

[0055] [Fig.4] is an exploded perspective view showing a cap capsule assembly of the refillable cosmetic container 100 according to an embodiment of the present invention. [Fig.5a] is a perspective view showing that the cap capsule assembly is in a closed position as shown in [Fig 3a] and [Fig.5b] is a perspective view showing that the cap capsule assembly is in an open position as shown in [Fig.3b] according to an embodiment of the present invention. [Fig.5c] is a sectional view showing that the cap capsule assembly is in an open position as shown in [Fig.5b] according to an embodiment of the present invention.

[0056] As shown in [Fig. 4], the cap capsule assembly includes a cap member 130 and a cap member 140. The cap member 130 includes a bottom member 131 and a cap body 132 extending axially from the bottom member 131. The bottom member 131 has one or more axial through holes 133. The cap body 132 is a cylinder and one or more windows 134 are formed at the bottom end of the cap body 132. In one example, a dome 135 extends from the bottom member 131 and is spaced from the cap body 132. In one example, the bottom member 131 includes a circumferential ridge 136 on its inner peripheral surface, as shown schematically in [Fig. 2].

[0057] The plug member 140 includes a cylindrical plug 141, a plug flange 143, and one or more axial protrusions 144. In one example, the plug member 140 further includes a stepped portion 142 so that it can be more easily inserted into the neck 122 of the inner container 120. The axial protrusion 144 includes a widening portion 1441 at its end. In other words, the axial protrusion 144 includes a shim 1442 on each lateral side thereof. During assembly, the axial protrusions 144 are inserted into the axial through holes 133, and the shim 1442 facilitates this insertion. After insertion, the widening portion 1441 will prevent the capsule member 130 from moving away from the stopper member 140. After insertion, the capsule member 130 can move upward on the outer peripheral surface of the stopper member 140. The circumferential ridge 136 will help to achieve a tight fit or transition fit between the cap member 130 and the cap member 140, so that the cap-cap assembly can be held in the closed position.

[0058] As shown in [Fig. 5a], when the cap capsule assembly is in the closed position, the bottom wall portion of the cylindrical cap 141 will block or close the window 134, and therefore the window 134 will be closed by the cap member 140, and at this time, no contents or cosmetics will be able to flow through the cap capsule assembly. As shown in [Fig. 5b], when the cap capsule assembly is in the open position, the bottom wall portion of the cylindrical cap 141 will leave the cap member 130 and therefore will no longer block the window 134, and therefore the window 134 will not be closed by the cap member 140, and at this time, the contents or cosmetics will be able to flow through the cap capsule assembly. As shown in [Fig.5c], when the cap capsule assembly is in the open position by pushing the cap bar 114 downward against the dome 135, which will be explained below, the capsule member 130 will move downward relative to the cap member 140, then the window 134 will be left open, and the contents or cosmetics will be allowed to flow through the window 134, and then through the open space between the axial protrusions 144 to flow out, as shown by the arrows in [Fig.5c]. .

[0059] During the refilling process, the contents or cosmetics are first loaded into the inner container 120. After the inner container 120 is filled with the predetermined amount of contents or cosmetics, the cap capsule assembly will be capped up to the neck 122 of the inner container 120, and the cap flange 143 of the cap member 140 will engage with the step portion 1222 of the neck 120 of the inner container 120. At this point, the cap capsule assembly is held in the closed position due to the interference fit or transition fit between the cap member 130 and the cap member 140 and thus the inner container 120 is also closed and sealed, and therefore no additional sealing or service capsules are required to seal the inner container.The inner container 120 is then ready for use and can also be used for inventory storage, with the contents or cosmetics being loaded and sealed therein.

[0060] During installation, the inner container 120 is inserted into the outer housing 110 through the bottom of the outer housing 110, and the guide mechanisms as explained above can facilitate this insertion. Referring to [Fig 3a], the inner container 120 full of the contents is inserted into the open bottom of the outer housing 110. Then, the cap bar 114 will contact the cap capsule assembly, more precisely, the push bars 1141 will contact the capsule member 130 (e.g., the dome 135 thereof). An insertion Additional insertion of the inner container 120 will cause the push bars 1141 to push the cap member 130 downward, and then the cap member 130 will move downward relative to the cap member 140 as shown in [Fig.5b]. At the end of the insertion, as shown in [Fig.3b], the inner container 120 is installed on the outer housing 110, and the refillable cosmetic container 100 in an open position in which the cosmetics in an inner container 120 of the refillable cosmetic container 100 can be dispensed.

[0061] In one embodiment of the present application, the outer housing 110 is provided with a circumferential groove 115 near the bottom end thereof. The circumferential groove 115 is formed on the inner peripheral surface of the outer housing 110. The circumferential groove 115 is configured to receive one or more circumferential bosses 1531 of the bottom ring 150, such that the bottom ring 150 is constrained by the outer housing 110 in the axial direction, as will be explained below.

[0062] [Fig. 8] is a perspective view showing a bottom ring 150 of the refillable cosmetic container 100 according to one embodiment of the present invention. In one example, the bottom ring 150 includes an outer cylinder 151 and an inner cylinder 152 extending axially from the outer cylinder 151, wherein the inner cylinder 152 is to be inserted into the outer housing 110 from the bottom, and the inner cylinder 152 is positioned between the wall of the outer housing 110 and the wall of the inner container 120 after the refillable cosmetic container 100 is installed.

[0063] In one example, the inner cylinder 152 is provided with one or more elastic wall pieces 153 by cutting some portions of the inner cylinder 152. For example, as shown in [Fig. 8], the elastic wall pieces 153 are formed by cutting an "n" shape in the inner cylinder 152. The elastic wall pieces 153 are free at their upper ends, so that they are elastic. In one example, the elastic wall piece 153 is provided with a circumferential boss 1531 on its outer peripheral surface, and the circumferential boss 1531 is to be received in the circumferential groove 115 of the outer housing 110, so that the bottom ring 150 is constrained by the outer housing 110 in the axial direction.

[0064] In one example, the outer cylinder 151 is provided with internal threads 154 on its inner peripheral surface. The internal threads 154 are to engage the external threads 123 on the inner container 120. Upon installation, the bottom ring 150 is first inserted into the outer housing 110, and the circumferential boss 1531 is received in the circumferential groove 115 of the outer housing 110, and therefore the bottom ring 150 can only rotate relative to the outer housing 110, but cannot move axially relative to the outer housing 110. Then, the inner container 120 is inserted into the outer housing 110 through the bottom ring 150. Then, the outer threads 123 on the inner container 120 will engage with the inner threads 154 on the bottom ring 150, at the same time the inner container 120 will be guided by the guide mechanisms as explained above (i.e., the axial extension ribs 1221 on the neck 122 of the inner container 110 will cooperate with the guide ribs 1131 to vertically guide the inner container 120) and therefore only vertical movement of the inner container 120 will be allowed. When rotating the bottom ring 150 clockwise (i.e., in the "CLOSE" direction as shown by the mark and arrow on the outer cylinder 151, as shown in [Fig.8]), the inner threads 154 on the bottom ring 150 engage with the outer threads 123 of the inner container 120 so as to push the inner container 120 upward, and then the inner container 120 is lifted to the installation position relative to the outer housing 110. There may be a clicking sound which may be an auditory feedback to the user indicating that the inner container 120 is already installed on the outer housing 110. Due to the structure of the cap capsule assembly, when a user assembles the refillable cosmetic container by rotational force, it would be a “push-open”. In the sense of transforming the rotary motion from the bottom ring into the linear motion of the inner container, the combination of the bottom ring and the inner container behaves to some extent like a ball screw or a lead screw.

[0065] With respect to a process of uninstalling the refillable cosmetic container 100, the user can rotate the bottom ring 150 counterclockwise (i.e., in an "OPEN" direction as shown by the mark and arrow on the outer cylinder 151 as shown in [Fig.8]), then the inner threads 154 of the bottom ring 150 engage with the outer threads 123 of the inner container 120 so as to pull the inner container 120 downward. Once the inner threads 154 of the bottom ring 150 disengage from the outer threads 123 of the inner container 120, the inner container 120 can be removed by exerting force on the exposed portions of the inner container 120. In this manner, a new inner container 120 can be installed on the outer housing 110, so that the cosmetic container 100 is refillable and reusable.

[0066] According to an embodiment of the present application, the discharge unit, and / or the inner container 110, and / or the outer housing 120, and / or the cap capsule assembly 130, 140 may be made of polypropylene (PP), or polyethylene (PE) including LDPE and HDPE, or polyethylene terephthalate (PET). PP is a more environmentally friendly solution than PVC, PCTA, PETG, ABS or PC due to its reduced emissions and it is lighter than other materials.

[0067] Aspects of the present disclosure have been described in detail with reference to the illustrated embodiments; however, those skilled in the art will recognize that numerous modifications may be made thereto without departing from the scope of the present disclosure. The present disclosure is not limited to the precise construction and compositions disclosed herein; all apparent modifications, changes, and variations of the foregoing descriptions are within the scope of the disclosure as defined by the appended claims. Furthermore, the present concepts expressly include all combinations and subcombinations of the foregoing elements and features. LIST OF DIGITAL REFERENCES
