Description

Technical Field

[0001] This utility model relates to the field of oil brush bottle technology, and in particular to an oil brush bottle. Background Technology

[0002] An oil brush bottle is a common kitchen tool used to store liquids such as cooking oil and soy sauce. It's used to brush oil onto food during grilling or other cooking activities. An oil brush bottle typically consists of a handle, a silicone brush head, and an oil reservoir. The silicone brush head is fixed to the bottom of the handle, and the handle is threaded to the opening of the reservoir. To use it, hold the handle and use the silicone brush head to dip a small amount of cooking oil from the reservoir and brush it onto the food surface. For example, Chinese patent application CN202322549914.0 discloses the following: a brush bottle with good sealing performance, including a handle, a silicone brush head, and an oil reservoir. The opening of the oil reservoir is connected to a connecting ring by a thread. The cross-section of the connecting ring is an isosceles trapezoidal structure. The inner wall of the connecting ring is provided with three equally spaced annularly distributed locking protrusions. The bottom of the handle is provided with a locking disc. The bottom center of the locking disc is provided with an installation tube. The silicone brush head is located at the bottom of the installation tube. The outer wall of the locking disc is provided with three equally spaced annularly distributed locking grooves. The locking protrusions can be screwed into the locking grooves. The outer wall of the locking disc above the locking grooves is provided with a sealing ring.

[0003] In existing technologies, oil brush bottles all use screw caps, which are cumbersome to use. They require two hands to operate: one hand holds the glass bottle, and the other hand holds the handle cap. Only by unscrewing the handle cap can one access the oil brush. Moreover, when carrying it outdoors, the tightness of the cap can affect the sealing effect, posing a risk of oil leakage and contaminating other items. Utility Model Content

[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] The present invention will be further described below with reference to embodiments.

[0037] This utility model provides an oil brush bottle, as shown in the following embodiment. Figures 1 to 5 This includes: bottle body 100, neck 200, and brush cap 300;

[0038] The neck 200 has an opening 210 and is detachably installed at the bottle mouth of the bottle body 100. The inner side wall of the neck 200 also has a slot 220.

[0039] The brush cover 300 is used to block the opening 210. The brush cover 300 is symmetrically equipped with two buttons 310. An elastic element 320 is provided between the two buttons 310. One end of the button 310 is provided with a pressing part 311, and the other end is provided with a locking part 312 that cooperates with the slot 220.

[0040] In this embodiment, the oil brush bottle mainly includes a bottle body 100, a neck 200, and a brush cap 300. The bottle body 100 is made of transparent glass and has a cylindrical oil storage chamber for storing liquids such as edible oil and soy sauce. A threaded structure is provided at the top of the bottle body 100. The matching neck 200 is made of plastic material such as PP, and its inner wall has a threaded structure that matches the bottle body 100. The neck 200 can be installed onto the bottle body 100 by rotating it clockwise. A circular opening 210 is provided in the middle of the neck 200, and a groove 220 is provided circumferentially on the inner wall of the neck 200. Possibly, there are two symmetrical grooves 220, or a complete circle of grooves is provided around the inner wall of the neck 200.

[0041] The brush cap 300 is injection molded from plastic, and its main body is a disc-shaped structure with a diameter matching the opening 210 of the neck 200. The button 310 includes a pressing part 311 and a locking part 312, which can be integrally molded and are "L"-shaped. The front end of the locking part 312 is wedge-shaped, and the rear end can be connected to the inner wall of the brush cap 300 through a stainless steel compression spring. In the locked and sealed state of the brush bottle, the elastic element 320 remains naturally extended, pushing the locking part 312 outward to form a mechanical interlock with the neck groove 220.

[0042] When the oil brush bottle is opened for use, the user pinches the pressing part 311, applying pressure to compress the elastic element 320, causing the engaging part 312 to disengage from the slot 220. At this point, lifting the brush cap 300 releases the locked seal, allowing the brush to be freely used for cooking. To reset, the user can align the brush with the neck 200 and press down; the wedge-shaped surface at the front of the engaging part 312 contacts the inclined surface of the slot 220, automatically compressing it. Once in place, the elastic element 320 springs back to lock. This locking mechanism effectively prevents oil leakage during outdoor transport.

[0043] Compared to traditional oil brush containers, this new oil brush bottle allows for one-handed operation through a locking mechanism and slot, simplifying the opening and closing process while ensuring a tight seal. It effectively prevents oil leakage and is particularly suitable for outdoor use.

[0044] In a preferred embodiment, such as Figure 3 and Figure 4 As shown, the brush cover 300 has a brush head 330 at the lower end and a brush handle 340 at the upper end, with two pressing parts 311 symmetrically arranged on the brush handle 340; the connection between the brush handle 340 and the brush cover 300 is provided with an avoidance opening 350 to avoid the movement path of the pressing part 311.

[0045] In this embodiment, a flat brush head 330 made of silicone material extends from the bottom of the brush cover 300, and a brush handle 340 is vertically connected to the top of the brush cover 300. An L-shaped clearance opening 350 is provided at the connection between the brush handle 340 and the brush cover 300. Two sets of pressing parts 311 are symmetrically arranged on the left and right sides of the clearance opening 350. The pressing parts 311 are independently formed and embedded into the brush cover 300. The lower ends of the two pressing parts 311 extend into plate-shaped engaging parts 312. The two pressing parts 311 are connected to the same elastic member 320 and are respectively located at both ends of the elastic member 320. When an external force is applied, the two pressing parts 311 retract towards the center, causing the engaging parts 312 to retract into the brush cover 300.

[0046] In a preferred embodiment, such as Figure 4 , Figure 6 and Figure 7As shown, the brush cap 300 includes an upper cover 360 and a lower cover 370; the lower surface of the upper cover 360 is provided with a first sliding groove 361; the upper surface of the lower cover 370 is provided with a second sliding groove 371; the first sliding groove 361 and the second sliding groove 371 enclose to form a sliding chamber for the engaging part 312; the outer end of the first sliding groove 361 is provided with a first notch 361a; the outer end of the second sliding groove 371 is provided with a second notch 371a; the first notch 361a and the second notch 371a enclose to form a through hole 362 for the engaging part 312 to protrude.

[0047] In this embodiment, the brush cap 300 adopts a dual-component injection-molded structure of an upper cap 360 and a lower cap 370, both of which can be circular. The guiding and avoidance structure of the upper cap 360, lower cap 370, and engaging portion 312 is specifically implemented as follows: A sliding chamber structure design is used, with a first sliding groove 361 injection-molded on the lower surface of the upper cap 360, forming a symmetrical U-shaped guide rail structure. The side walls of this guide rail are adapted to the width of the engaging portion 312, preventing the engaging portion 312 from shifting or moving within the width direction of the first sliding groove 361. A second sliding groove 371 corresponding to the first sliding groove 361 is machined on the upper surface of the lower cap 370. The second sliding groove 371 and the first sliding groove 361 are mated together to form a closed slide, preventing the engaging portion 312 from moving up and down within the U-shaped guide rail of the first sliding groove 361. This further ensures that the engaging part 312 can only reciprocate in a straight line along the length direction of the engaging part 312 within the limiting cavity.

[0048] A first notch 361a is made at the edge of the upper cover 360, and a second notch 371a is made at the corresponding position of the lower cover 370. The first notch 361a and the second notch 371a are combined to form a through hole 362, allowing the protruding end of the engaging part 312 to extend out. Through the precise fit of the split brush cover, the high-precision linear guidance of the engaging part 312 is achieved in a limited space.

[0049] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 7 As shown, the upper surface of the pressing part 311 is provided with a first locking point 311a, and the lower surface of the engaging part 312 is provided with a second locking point 312a; the brush handle 340 is provided with a first baffle 341, and the upper cover 360 is provided with a second baffle 363. When the elastic member 320 is extended, the first baffle 341 interferes with the first locking point 311a, and the second baffle 363 interferes with the pressing part 311; the second slide groove 371 is provided with a third baffle 371b. When the elastic member 320 is pressed, the third baffle 371b interferes with the second locking point 312a.

[0050] In this embodiment, since the pressing part 311 is relatively long, interference structures are provided at the top, middle and bottom to ensure that the pressing part 311 will not shift randomly during the pressing process, but will only slide along the direction of force application.

[0051] The upper surface of the pressing part 311 is provided with a raised cylindrical first locking point 311a. The brush handle 340 has a hollow cylindrical structure. The first locking point 311a and the hollow inner wall of the brush handle 340, i.e., the first baffle 341, form a dynamic engagement. This ensures that when the pressing part 311 extends outward, the plane of the first locking point 311a makes surface contact with the inner wall of the first baffle 341. At the same time, the upper surface of the pressing part 311 is flat, and the bottom surface of the brush handle 340 connected to the first baffle 341 is also flat. The two form surface contact, restricting the pressing part 311 from sliding along the plane.

[0052] The upper cover 360 is provided with a second baffle 363. The pressing part 311 has vertical surfaces on both sides that form surface contact with the upper cover 360 provided with the second baffle 363, forming an interference limit when the pressing part 311 slides outward.

[0053] The lower surface of the engaging part 312 is provided with a cylindrical second locking point 312a, and the second sliding groove 371 is provided with a third baffle 371b on the path of the second locking point 312a sliding inward. When the engaging part 312 slides inward to the limit position, the third baffle 371b and the second locking point 312a form an interference limit.

[0054] In a preferred embodiment, such as Figure 1 , Figure 5 , Figure 7 As shown, the lower cover 370 has a first retaining part 372 around its periphery, and the first retaining part 372 is fitted with a first sealing ring 373; the inner sidewall of the neck 200 is provided with an annular platform 230; the first sealing ring 373 and the annular platform 230 are sealed together.

[0055] In this embodiment, an annular first retaining portion 372 is provided at the bottom edge of the lower cover 370, and the first sealing ring 373 is made of food-grade silicone material, with its main body in the shape of an O-ring. During assembly, the first sealing ring 373 is tightly fitted onto the first retaining portion 372, pressing against the annular platform 230. The first sealing ring 373 undergoes radial elastic deformation, and its outer diameter expands to fit tightly against the annular platform 230, forming a sealing barrier and effectively blocking the path of medium leakage along the gap.

[0056] In a preferred embodiment, such as Figure 6 and Figure 7 As shown, the lower surface of the upper cover 360 is provided with a protrusion 364, and the upper surface of the lower cover 370 is provided with an insertion hole 374. The protrusion 364 and the insertion hole 374 are inserted and matched to connect the upper cover 360 and the lower cover 370.

[0057] In this embodiment, the positioning and connection structure between the upper cover 360 and the lower cover 370 is mainly achieved through an interlocking fit. Specifically, multiple cylindrical protrusions 364 are symmetrically arranged on the lower surface of the upper cover 360. Correspondingly, multiple insertion holes 374 are provided on the upper surface of the lower cover 370. The depth of the insertion holes 374 is adapted to the length of the protrusions 364, and the protrusions 364 and the insertion holes 374 are interference-fitted.

[0058] During assembly, first keep the upper cover 360 and the lower cover 370 vertically aligned, align the axis of the protrusion 364 with the center of the insertion hole 374, apply axial pressure to make the protrusion 364 fully inserted into the insertion hole 374, and the assembly of the upper cover 360 and the lower cover 370 is completed.

[0059] It is also possible that the upper cover 360 and the lower cover 370 are assembled and connected by means of screws or other methods.

[0060] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the lower surface of the neck 200 is provided with a second retaining part 240, and the second retaining part 240 is fitted with a second sealing ring 250, which is sealed to the bottle mouth of the bottle body 100.

[0061] In this embodiment, the lower surface of the neck 200 is machined with an annular second retaining portion 240, and the second sealing ring 250 is made of food-grade silicone, the cross-sectional shape of which matches the second retaining portion 240, and is embedded in the groove through an interference fit. When the neck 200 is screwed to the threaded bottle neck of the bottle body 100, the second sealing ring 250 is compressed and deformed, forming a surface contact seal with the annular plane at the top of the bottle neck. This structure can effectively prevent oil from seeping out of the bottle body 100 through the threaded gap.

[0062] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the elastic element 320 is a spring, and the inner side wall of the pressing part 311 is provided with a spring holder 311b, on which the spring is sleeved.

[0063] In this embodiment, a cylindrical spring holder 311b is integrally injection molded on the inner wall of the pressing part 311, and the axis of the spring holder 311b extends along the sliding direction of the pressing part 311. During assembly, the spring is laterally sleeved on the spring holder 311b, with both ends of the spring abutting against the opposing inner walls of the two spring holders 311b respectively. The spring holder 311b guides the spring and prevents it from tilting. The outer diameter of the spring holder 311b maintains a clearance fit with the inner diameter of the spring, ensuring smooth assembly and limiting radial displacement of the spring. When a pressing operation is applied, the spring holder 311b acts as a guide shaft to constrain the elastic element 320 to only undergo axial compression, preventing jamming caused by spring twisting. This structure stabilizes the spring's working stroke and improves the linear feel of the opening action.

[0064] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
