Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic packaging, in particular to a telescopic airtight perfume cream. Background Art

[0002] Deodorant is a solid perfume, which is easier to carry and can be applied to the skin. The main ingredients of deodorant are essence and beeswax. It is solid at room temperature and melts when heated. The fragrance lasts for about 3-4 hours. After applying deodorant on the skin, the skin will be moisturized and oil will be left on the skin. People with oily skin may not like it very much, so it is more suitable for use in winter. At present, in order to increase the storage capacity of deodorant, the length of the storage tube is usually designed to be longer, which causes the lifting structure of the deodorant to be extended at the same time, which leads to a problem. The overall length of the deodorant is relatively long, which is extremely inconvenient to put in a small bag, and it is not convenient and beautiful to use, so it needs to be improved.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art belonging to the technical field of the present utility model. The terms used herein in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0019] As shown Figures 1 to 4 in the figure, a telescopic airtight deodorant stick includes a barrel body 1, an outer cover 2, an inner cover 3, a base 4, a first screw member 5, a second screw member 6 and a piston 7. The inner cover 3 is installed at the upper port of the barrel body 1. An outlet 31 is provided on the inner cover 3. The outer cover 2 is detachably installed outside the barrel body 1 and covers the inner cover 3. The base 4 is movably installed at the lower end of the barrel body 1. The first screw member 5 penetrates through the base 4 and extends into the barrel body 1. The first screw member 5 is in screw connection with the base 4. The second screw member 6 is spirally sleeved inside the first screw member 5. The piston 7 is installed at the top of the second screw member 6. The edge of the piston 7 is in movable contact with the inner wall of the barrel body 1. Specifically, in this embodiment, the barrel body 1 is made of metal or plastic and is tubular. The inner cover 3 is installed at the upper port of the barrel body 1 through bone position fitting, or can also be assembled by means of screw connection. In order to prevent the fragrance of the deodorant stick from wafting out along the outlet 31 of the inner cover 3 when not in use, an outer cover 2 is installed outside the inner cover 3. The outer cover 2 can also be connected to the port of the barrel body 1 by means of snap connection or screw connection. The deodorant stick is contained in the barrel body 1. In order to continuously extrude the deodorant stick during the application process, a first screw member 5, a second screw member 6 and a piston 7 are provided in the barrel body 1. In order to reduce the overall length of the barrel body 1, a double-screw method is adopted, that is, the base 4 is screwed to the lower end of the barrel body 1, and the first screw member 5 is in screw connection with the base 4. When the base 4 is rotated, the first screw member 5 can be lifted and lowered in the barrel body 1. Similarly, when the first screw member 5 rises to the top position and the base 4 is continuously rotated, the second screw member 6 can be driven by the first screw member 5 to be lifted and lowered in the barrel body 1, so that it is not necessary to design a longer screw member. We split it into the first screw member 5 and the second screw member 6. When there is more deodorant stick in the barrel body 1, only by driving the first screw member 5 to be lifted and lowered through the base 4, the deodorant stick can be extruded. When there is less remaining deodorant stick, at this time, the second screw member 6 needs to be screwed out of the first screw member 5 and raised, so as to cooperate with the piston 7 to extrude the deodorant stick. The double-screw design can make the length of the barrel body 1 designed shorter, avoid designing a longer extrusion structure, reserve space for storing more deodorant stick, and the use experience is excellent.

[0020] As shown Figures 2 to 4 in the figure, both the second screw member 6 and the first screw member 5 are tubular. A feed port 41 is provided at the bottom of the base 4. The second screw member 6 is communicated with the feed port 41 through the first screw member 5. Specifically, in this embodiment, when filling and filling the deodorant stick, the deodorant stick can be poured into the barrel body 1 through the feed port 41, and the pouring is extremely simple and convenient. It can be understood that in order to prevent the piston 7 from blocking the pouring, an opening can be provided at the top of the piston 7 so that the deodorant stick can be poured into the barrel body 1 under high pressure.

[0021] As Figures 2 to 4 shown, a plug 8 is installed inside the second helical member 6, and the top of the plug 8 protrudes outside the piston 7. Specifically, the plug 8 is made of rubber and is inserted into the second helical member 6 through the first helical member 5 to block the filling channel of the solid perfume, preventing the solid perfume from leaking out along the channels of the first helical member 5 and the second helical member 6 during use.

[0022] As Figures 2 to 4 shown, a silica gel pad 21 is provided inside the outer cover 2, and the silica gel pad 21 is used to block the discharge port 31. The silica gel pad 21 blocks the discharge port 31 with high fitting degree and good airtightness, avoiding the smell of the solid perfume from emitting.

[0023] As Figures 2 to 4 shown, the base 4 further includes an outer seat 42 and an inner sleeve 43. The outer seat 42 is sleeved on the lower outer side of the barrel body 1, the feed port 41 is provided on the outer seat 42, the inner sleeve 43 is screwed on the outer seat 42, and the first helical member 5 movably penetrates through the inner sleeve 43. Specifically, the outer seat 42 is movably clamped at the lower end of the barrel body 1, so that the outer seat 42 is rotatable. The inner sleeve 43 and the outer seat 42 are integrated. A threaded ring is provided on the inner circumference of the upper end of the inner sleeve 43 for mating connection with the thread on the outer side of the first helical member 5. When the outer seat 42 is rotated, the inner sleeve 43 rotates synchronously, thereby causing the first helical member 5 to rotate and move up and down.

[0024] As Figures 3 to 4 shown, a stop ring 431 is provided on the inner side of the upper port of the inner sleeve 43, and a stop piece 51 cooperating with the stop ring 431 is provided at the lower end of the first helical member 5 to prevent the first helical member 5 from disengaging from the upper end of the inner sleeve 43 during the helical lifting and lowering process in the inner sleeve 43.

[0025] As Figures 2 to 4 shown, the side part of the piston 7 is recessed towards one side of its central axis, so that both ends of the piston 7 are in contact with the inner wall of the barrel body 1, reducing the contact area and making the resistance of the piston 7 to move up and down smaller.

[0026] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
