Cosmetic applicator with rotary cartridge

Abstract

A cosmetic applicator includes a body which includes a tip part and an extension which has a threaded portion. A case has a rotary member threadedly connected to the threaded portion. A contact member is received in the case which has a contact portion located corresponding to the shoulder of the body. A liquid supply unit is axially received in the body and the case, and has a liquid tube, a duct and a guide tube. The liquid tube contacts the contact member. The duct is inserted in the liquid tube and has a passage. A sealing member is removably located at the duct to seal or open the guide tube. A clip is connected to a groove between the case and the body before first use. The clip is removed and the case is rotated to move the sealing member to allow cosmetic liquid to reach the tip part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(6) Referring to FIGS. 1 to 3, the cosmetic applicator of the present invention comprises a body 1 having a space defined axially therein. A tip part 11 is connected to the first end of the body 1, and an extension 12 extends from the second end of the body 1 and has a threaded portion 121 formed thereon. The body 1 has a shoulder 13 formed at the conjunction portion between the extension 12 and the body 1. The diameter of the shoulder 13 is larger than that of the threaded portion 121.

(7) A case 2 is connected to the body 1 and has a room 21 which communicates with the space of the body 1. A rotary member 22 is threadedly connected to the threaded portion 121 of the body 1. A contact member 23 is received in the room 21 of the case 2. In this embodiment, the contact member 23 is a T-shaped member. The case 2 has a contact portion 24 which is located corresponding to the shoulder 13 of the body 1. In a preferred embodiment, the contact member 23 and the case 2 are a one-piece part. In a preferred embodiment, a groove 25 is formed between the shoulder 13, the contact portion 24 and the extension 12. A clip 3 is engaged with the groove 25 and has a hold portion 31 which matches with the outer periphery of the extension 12 to connect the clip 3 to the extension 12. In a preferred embodiment, the clip 3 is a C-shaped clip. The top face and the bottom face of the hold portion 31 respectively contact the shoulder 13 and the contact portion 24. The clip 3 has a handle 32 extending from the outside of the hold portion 31.

(8) A liquid supply unit 4 is axially received in the space of the body 1 and the room 21 of the body 2. The liquid supply unit 4 has a liquid tube 41, a duct 42 and a guide tube 43. The liquid tube 41 has the first end thereof contacting the contact member 23. The liquid tube 41 and the duct 42 are received in the room 21 of the case 2. The guide tube 43 is located in the space of the body 1. The contact member 23 has a recess 231 in which the liquid tube 41 is inserted.

(9) The duct 42 is inserted in an opening 411 defined in the first end of the liquid tube 41, and the flange 423 contacts the first end having the opening 411 of the liquid tube 41. The duct 42 has a passage 421 defined axially therethrough. A sealing member 422 is received in the duct 42 and removably located at the first end of the duct 42 that faces the first end of the liquid tube 41. The diameter of the sealing member 422 is larger than an opening in the second end of the guide tube 43, so as to seal or open the guide tube 43. The liquid tube 41 has a rod 412, and the diameter of the rod 412 is smaller than the inner diameter of the passage 421.

(10) The tip part 11 is connected to the first end of the guide tube 43, and the diameter of the second end of the guide tube 43 is smaller than the inner diameter of the passage 421. The second end of the guide tube 43 is located in to the passage 421. The second end of the guide tube 43 contacts the sealing member 422. The guide tube 43 is longer than the duct 42. A cap 5 is axially connected to the first end of the body 1.

(11) Because the conventional cosmetic applicator is easily rotated or pushed unintentionally when the cosmetic applicator is not in use, and releases too much cosmetic liquid as a result, the present invention is structured to eliminate that shortcoming. As shown in FIG. 3, the clip 3 is engaged with the groove 25 between the body 1 and the case 2 to function as a safety device and prevent the user from unintentionally rotating or pushing the cosmetic applicator. The fist time the cosmetic applicator is used, the clip 3 is removed from the groove 25 by pulling the handle 32 outward, and the case 2 is rotated by rotating the rotary member 22 along the threaded portion 121. The body 1 is located at an initial position P1, and the sealing member 422 seals the second end of the guide tube 43.

(12) As shown in FIG. 4, when the case 2 is rotated by rotating the rotary member 22 along the threaded portion 121 to make the distance D between the shoulder 13 and the contact portion 24 be reduced to an open position P2, because the liquid tube 41 is contacts the inner end of the recess 231, and the flange 423 of the duct 42 contacts the first end of the liquid tube 41 having the opening 411, so that the when the case 2 is rotated to move toward the tip part 11, the contact member 23 contacts the liquid tube 41 to move the liquid tube 41 and the duct 42 move axially toward the tip part 11. At the same time, the guide tube 43 is inserted into the passage 421, the sealing member 422 is pushed by the second end of the guide tube 43 to move axially in the passage 421. The distance D between the shoulder 13 and the contact portion 24 is larger than the distance D that the sealing member 422 is separated from the passage 421 of the duct 42. The sealing member 422 moves a distance longer than the distance D by the guide tube 43 and is located in the liquid tube 41.

(13) As shown in FIG. 5, by shaking the cosmetic applicator of the present invention, the rod 412 stirs the cosmetic liquid in the liquid tube 41, and the sealing member 422 is displaced from the second end of the guide tube 43 due to the shaking, so that the cosmetic liquid in the liquid tube 41 flows through the gap between the sealing member 422 and the duct 42, and flows to the tip part 11 via the guide tube 43. The cosmetic liquid is evenly and smoothly output from the tip part 11 because the rod 412 and the sealing member 422 stir the cosmetic liquid.

(14) After the cosmetic applicator is used, the cap 5 is re-capped to the first end of the body 1 to hide the tip part 11 in the cap 5. When the cosmetic applicator is put horizontally or vertically, because the cosmetic liquid has viscosity so that the cosmetic liquid is stably received in the liquid supply unit 4 and the tip part 11 and does not flow. When the cosmetic applicator is used again, by shaking the cosmetic applicator to make the sealing member 422 is displaced from the second end of the guide tube 43, and the rod 412 and the sealing member 422 stir the cosmetic liquid that is gradually subsided, and the cosmetic liquid in the liquid tube 41 flows through the gap between the sealing member 422 and the duct 42, and flows to the tip part 11 via the guide tube 43 for being evenly used.

(15) While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
