Description

Technical Field

[0001] The utility model relates to a valve structure, in particular to a valve structure with environmental protection effect. Background Art

[0002] The applicant has previously developed a valve structure, which is installed at the opening of the container. The valve structure consists of a sleeve, a hollow piston rod, a metal spring and a discharge head. The sleeve is provided with a discharge port near the bottom. The rod body at one end of the hollow piston rod is sleeved with the metal spring and then placed in the accommodating space in the sleeve. The other end is sleeved with the discharge head. Finally, the sleeve is sleeved at the opening of the container. The compression force and reaction force of the metal spring cause the piston rod to move axially, thereby realizing the movable opening and closing of the discharge port, so as to control whether the cosmetic liquid in the container can flow out while achieving the effect of airtightness.

[0003] However, after long-term use, the cosmetic liquid will inevitably flow into the inside of the dispensing head through the gaps between the components. If it accidentally contacts the metal spring, in addition to affecting the quality of the cosmetic liquid, the metal spring may also rust. Moreover, since most metal springs are spiral-shaped, the cosmetic liquid is easily stuck in the gaps between them, affecting the elastic force of the metal spring. In addition, after using up the cosmetic liquid, consumers usually send the entire cosmetic container for recycling. However, due to the difference in materials, the recycling company must first remove the metal spring for recycling, and cannot recycle it together with the plastic dispensing head and container. Otherwise, it will cause damage to the recycling equipment, which will also cause trouble for the recycling company and is not environmentally friendly.

[0004] In order to solve the conventional problems, the applicant, based on many years of experience in manufacturing, developing and designing related products, has conducted prototype tests and related improvements many times, and finally obtained a practical utility model that can completely solve or effectively improve the conventional deficiencies.

[0031] See also Figures 1 to 4 As shown, the utility model discloses a valve structure with environmental protection effect, which includes:

[0032] A coating head 10 is provided with a plurality of first discharge holes 11. In the embodiment of the utility model, the coating head 10 is round in shape, and the material of the coating head 10 is thermoplastic polyester elastomer (TPEE).

[0033] A piston rod 20, the piston rod 20 has a convex ring disk 21, a fixed section 22 is extended at one end of the convex ring disk 21, and a rod body 23 is extended at the other end. The fixed section 22 is provided for the coating head 10 to be mounted, and the end surface of the fixed section 22 is provided with a plurality of second discharge holes 221. The outer surface of the rod body 23 is adjacent to the convex ring disk 21 to form a stop edge 231 radially. In addition, a through groove 24 is axially penetrated by the piston rod 20, and the through groove 24 is connected to the second discharge holes 221.

[0034] A sleeve 30, one end of which is axially provided with a receiving groove 31, and the rod 23 is sleeved in the receiving groove 31. The sleeve 30 has an axial body 32, one end of which is gradually reduced to form a ring bottom 33, and the outer edge of the other end is expanded to form a peripheral portion 34. The inner bottom surface of the ring bottom 33 is provided with a conical ring protrusion 331, and the periphery of the ring bottom 33 is provided with at least one discharge port 332, and the discharge port 332 is communicated with the receiving groove 31. In addition, the inner wall surface of the sleeve 30 is provided with a limiting portion 35 at the connection between the axial body 32 and the ring bottom 33, and the limiting portion 35 is abutted against the outer wall surface of the rod 23.

[0035] An elastic element 40, which is in the shape of a hollow cylinder as a whole and is made of soft plastic. In the embodiment of the utility model, the soft plastic is silicone or thermoplastic elastomer (TPE), wherein the wall surface of the elastic element 40 is flat, but the state of the elastic element 40 is not limited to that shown in the figure. The elastic element 40 is sleeved on the shaft 23 of the piston rod 20 and is located in the receiving groove 31 of the sleeve 30, and has a first end 41 and a second end 42 arranged opposite to each other, the first end 41 abuts against the stopping edge 231, and the second end 42 abuts against the limiting portion 35.

[0036] See also Figure 5 and Figure 6 As shown, the utility model is used in combination with an outer cover 50 and a bottle body 60 containing cosmetic liquid. The inner wall surface of one end of the outer cover 50 is provided with a screw-fitting portion 51 and a pressing edge 52 is formed. An opening 61 is axially provided at one end of the bottle body 60. The sleeve 30 is sleeved on the inner edge of the opening 61 so that the circumferential portion 34 stops at the end surface of the opening 61, and a threaded portion 62 is provided on the outer edge of the opening 61. The threaded portion 62 can be screwed with the screw-fitting portion 51 of the outer cover 50 so that the outer cover 50 is covered on the applicator head 10.

[0037] When the utility model is not in use, the outer cover 50 is screwed onto the bottle body 60, wherein the threaded portion 62 of the bottle body 60 is correspondingly screwed and fastened with the screw-fitting portion 51 of the outer cover 50, and the convex ring disk 21 of the piston rod 20 is pressed by the pressing edge 52 of the outer cover 50, so that the convex ring disk 21 is pressed against the circumferential portion 34 of the sleeve 30, and at the same time, the stopping edge 231 compresses the elastic element 40, so that the rod body 23 moves toward the annular protrusion 331 and forms an embolism with the annular protrusion 331 to close the discharge ports 332, so that the cosmetic liquid in the bottle body 60 cannot flow out.

[0038] See also Figure 7 And with Figure 6 As shown, when the user wants to apply the cosmetic liquid, the outer cover 50 is first unscrewed, and the stop edge 231 of the piston rod 20 is pushed by the elastic force of the elastic element 40, driving the piston rod 20 to move axially, so that the convex ring plate 21 is away from the circumferential portion 34 of the sleeve 30, and the rod body 23 is away from the annular protrusion 331. At this time, the cosmetic liquid in the bottle body 60 can flow into the through groove 24 from each of the discharge ports 332, and flow out through the second discharge holes 221 and the first discharge holes 11, and can be used with the application head 10 to be evenly applied to the use area. Therefore, through the operation of the piston rod 20, the sleeve 30 and the elastic element 40, in addition to making the cosmetic liquid flow out evenly and quantitatively, it can also effectively prevent the cosmetic liquid from leaking out, achieve an airtight effect, and isolate the cosmetic liquid from air pollution.

[0039] Continue reading Figures 8 to 10 As shown, it is a second embodiment of the utility model, which is different from the first embodiment in that the material of the applicator head 10 is a sponge, and the first discharge holes 11 are not provided (because the sponge can directly allow the cosmetic liquid to penetrate), and a connecting portion 12 is extended at one end of the applicator head 10, and the fixed section 22 of the piston rod 20 has a discharge head 222, and the connecting portion 12 is sleeved on the discharge head 222, and the discharge head 222 is axially penetrated by a through hole 223, and the through hole 223 is connected to the piston rod 20. The through grooves 24 are interconnected, so the fixed section 22 does not need to be provided with the second discharge holes 221. In addition, it also includes a neck sleeve 25, which is hollow and has a fitting portion 251 formed at one end to fit the fixed section 22 and abut against the convex ring disk 21, and a binding portion 252 formed at the other end. The binding portion 252 is for the coupling portion 12 of the application head 10 to be inserted into, so that the coupling portion 12 is confined between the fixed section 22 and the neck sleeve 25, thereby preventing the application head 10 from falling off.

[0040] The wall surface of the elastic element 40 disclosed in the second embodiment is wavy, so the compression and rebound capabilities of the elastic element 40 can be improved.

[0041] Therefore, since the elastic element 40 is made of soft plastic, it can be recycled together with the plastic applicator head 10, the outer cover 50 and the bottle body 60, which is environmentally friendly. The combination and operation of the piston rod 20, the sleeve 30 and the elastic element 40 can achieve an airtight effect, which can effectively prevent external air and overflowed cosmetic liquid from flowing back into the bottle body 60 to ensure that the quality of the internal cosmetic liquid is not affected. At the same time, it can prevent the elastic element 40 from rusting, thereby increasing its service life.
