[0002] In daily life, people often encounter some problems when using oil can to pour oil. The spout of the traditional oil can cover is short, and when pouring oil into some containers with small caliber or deep position, the spout is difficult to accurately approach the filling port, resulting in difficulty in pouring oil, and during the pouring process, the oil liquid is easy to be spilled, not only causing waste, but also dirtying the surrounding environment, which is very troublesome to clean up. If the spilled oil liquid contacts open flame, there is a safety hazard.

[0003] To this end, some oil bottle caps with oil nozzle telescopic function are launched on the market to overcome the inconvenience of pouring oil and the problem of oil liquid spilling. The existing telescopic oil bottle cap structure is generally composed of an outer sleeve, an oil nozzle, a spring, a top cover and the like. Under the action of the spring, the oil nozzle can be stretched out of the inner cavity of the outer sleeve to facilitate pouring oil. When not in use, the oil nozzle can be compressed back into the outer sleeve through the bottle cap. However, the existing telescopic oil bottle cap not only has many parts, but also is difficult to assemble. During assembly, the spring needs to be aligned with the bottom of the outer sleeve first, then the spring is installed into the outer sleeve, and then the oil nozzle is aligned with the spring and installed into the outer sleeve. If the two ends of the spring are not aligned well, the spring will be skewed or not abutted in place, resulting in the problem that the oil nozzle cannot be smoothly telescoped. It can be seen that the existing telescopic oil bottle cap has the problems of many parts, high assembly difficulty and low production efficiency, which need to be solved.

[0031] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0032] Example 1

[0033] The present embodiment discloses a telescopic oil bottle cap integrated with an oil nozzle elastic member, referring to Figures 1-6It includes an oil bottle plug 1 and a telescopic oil nozzle 2. The oil bottle plug 1 is installed as a component matched with the oil bottle mouth, and an inverted oil cavity 11 is arranged inside. The telescopic oil nozzle 2 includes an oil nozzle part and an elastic part 23. The oil nozzle part is movably sleeved in the inverted oil cavity 11 of the oil bottle plug 1, and a stroke limiting structure is arranged between the oil nozzle part and the oil bottle plug 1. One end of the elastic part 23 is integrally formed and connected with the oil nozzle part, and the other end of the elastic part 23 away from the oil nozzle part acts on the lower end of the oil bottle plug 1. Different from the traditional structure of the oil nozzle and the spring being separated, the oil nozzle part and the elastic part 23 are designed to be integrally injection molded in the present scheme, and a spring does not need to be additionally installed. Not only the number of parts is reduced, but also the assembly steps are simplified. Only the telescopic oil nozzle 2 needs to be installed from the upper opening of the inverted oil cavity of the oil bottle plug 1, which greatly improves the production efficiency and reduces the production cost.

[0034] As a preferred scheme, referring to Figure 3 , the oil nozzle part includes a slidingly sleeved outer oil nozzle 21 and an inner oil nozzle 22. The elastic part 23 is integrally formed at the lower end of the inner oil nozzle 22. The top of the elastic part 23 forms a limiting boss 233 at the lower end of the inner oil nozzle 22. The inner wall of the outer oil nozzle 21 is limited by the limiting boss 233 through the limiting step 211. This design realizes the telescopic function of the oil nozzle through the sliding sleeve of the outer oil nozzle 21 and the inner oil nozzle 22. The limiting boss 233 is formed by the structure of the elastic part 23 itself. The cooperation of the limiting boss 233 and the limiting step 211 can effectively prevent the oil nozzle from over-telescoping or falling off during telescoping, thereby improving the stability and safety of the product. In other embodiments, the oil nozzle part can be single, three or more sections, and the elastic part 23 is integrally formed with the innermost section of the oil nozzle.

[0035] As a preferred scheme, the inner oil nozzle 22 and the elastic part 23 are integrally injection molded by pp material. The pp material of the integrally injection molded elastic part 23 in the present scheme has better material stability than the traditional independent stainless steel spring. The pp material is not easy to react with the liquid in the bottle, has stronger resistance to acid and alkali, and has higher hygiene level and service life.

[0036] As a preferred scheme, the stroke limiting structure is that the lower end of the outer oil nozzle 21 is provided with a clamping convex edge 212, and the inner wall of the inverted oil cavity 11 of the oil bottle plug 1 is limited by the cooperation of the clamping convex edge 212 and the stop step 111. The elastic modulus of the clamping convex edge 212 is configured to allow elastic contraction to be embedded in the top opening of the inverted oil cavity 11 and to be elastically restored to cooperate with the stop step 111 for clamping. The stop step 111 cooperates with the clamping convex edge 212 for clamping to limit the outer oil nozzle 21 from separating from the oil bottle plug 1. This stroke limiting structure can effectively limit the telescopic stroke of the oil nozzle, ensure that the oil nozzle will not be over-extended or retracted during use, and improve the accuracy and reliability of oil pouring.

[0037] As a preferred solution, referring to Figure 4 , the inner side wall of the outer nozzle 21 is provided with an inner nozzle limiting plane 213, and the outer periphery of the inner nozzle 22 is in a conformal fit with the inner side wall of the outer nozzle 21. The design of the inner nozzle limiting plane 213 and the conformal fit can ensure that the inner nozzle 22 moves linearly and smoothly in the axial direction within the outer nozzle 21. In addition, the inner side wall of the pouring cavity 11 of the oil bottle plug 1 is also provided with a bottle nozzle limiting plane 112, and the outer periphery of the telescopic oil nozzle 2 (i.e. the periphery of the outer nozzle 21) is in a conformal fit with the inner side wall of the pouring cavity 11 of the oil bottle plug 1. The design of the bottle nozzle limiting plane 112 and the conformal fit can ensure that the outer nozzle 21 moves linearly and smoothly in the axial direction within the pouring cavity 11, avoiding the rotation of the oil nozzle during the telescopic process, and improving the use performance and user experience of the product. Further, the outer periphery of the elastic part 23 is in a conformal fit with the inner side wall of the outer nozzle 21. This design can further optimize the fit between the elastic part 23 and the outer nozzle 21, ensuring that the elastic part 23 can be telescoped under the guidance of the inner side wall of the outer nozzle 21 during the working process, and improving the stability and reliability of the telescoping.

[0038] As a preferred solution, referring to Figures 5-6 , the oil bottle plug 1 is internally provided with a top-to-bottom through-flow cavity 12, and the top of the oil bottle plug 1 is provided with a backflow ring 13, which surrounds the pouring opening of the pouring cavity 11 and the top opening of the backflow cavity 12. The design of the backflow cavity 12 and the backflow ring 13 can effectively collect the backflow of oil that may occur during the pouring process, prevent the spilling of oil, keep the surrounding environment clean, and also avoid the influence of oil residues on the quality of the oil product, thereby improving the practicality and safety of the product. In addition, the backflow cavity 12 is preferably designed on the side of the pouring cavity 11 close to the bottle nozzle limiting plane 112, so as to make full use of the space on the side of the bottle nozzle limiting plane 112, and make the pouring opening and the backflow opening larger in the limited space, thereby optimizing the structure.

[0039] As a preferred solution, referring to Figures 5-6 , the oil bottle cap further comprises a top cover 3, the bottom of the top cover 3 is provided with a sealing ring 31 and a buckle ring 32, the top of the oil bottle plug 1 is provided with a buckle ring 14, the buckle ring 14 surrounds the outside of the backflow ring 13, the sealing ring 31 abuts the inner side of the backflow ring 13, the surface of the buckle ring 32 is provided with a protrusion, and the buckle ring 14 is provided with a groove matched with the protrusion of the buckle ring 32. The design of the top cover not only enhances the sealing performance of the oil bottle cap to prevent oil leakage, but also realizes the firm connection of the top cover and the oil bottle plug through the buckle structure, which is convenient for opening and closing. When the top cover 3 is buckled on the oil bottle plug 1, the top cover 3 acts on the top of the telescopic oil nozzle 2, compresses the telescopic oil nozzle 2 into the pouring cavity 11 against the elastic force of the elastic part 23, and when the top cover 3 is opened, the elastic part 23 rebounds to push out the telescopic oil nozzle 2, which is convenient for pouring. In other embodiments, the oil bottle cap can also not contain a top cover, but use the cap of the soy sauce bottle itself to replace the top cover.

[0040] Embodiment 2

[0041] The embodiment discloses a telescopic oil bottle cap with an oil nozzle elastic element, referring to Figure 7 The difference between the embodiment and the embodiment 1 is that the elastic part 23 of the embodiment comprises a plurality of spaced elastic rings 231 and double helix elastic arms 232 connecting adjacent elastic rings 231. The scheme utilizes the characteristics of the integrated injection molding of the elastic part 23 and the oil nozzle part, and the elastic part 23 can be designed in multiple elastic special structures. In addition to the conventional single helix spring structure of the elastic part 23 in the embodiment 1, the elastic part 23 can also be designed in the special spring structure of the embodiment. The elastic part 23 of the structure can provide stable elastic support, ensure the stability and reliability of the oil nozzle in the telescopic process, and the design of the double helix elastic arm can increase the elasticity and durability of the elastic part 23, prolong the service life of the product.
