Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic packaging bottles, in particular to a cosmetic packaging bottle with a single-handed opening lid. Background Art

[0002] A cosmetic bottle is a container used to hold cosmetics. Bottles for creams are generally called cream jars. These bottles typically consist of a body and a cap, which are typically threaded or snap-fitted together. Users typically open the bottle by twisting the cap or pressing the snap. To facilitate one-handed operation, a range of cosmetic bottles designed for one-handed opening have emerged in the prior art. For example, CN116158612A discloses a single-handed push-to-open cosmetic container. The container has a snap-fit ​​groove on the bottle body, and the bottle cap includes an outer cap, a snap claw, and an inner cap. The snap hooks of the snap claws are equidistantly L-shaped and arranged downward and inward. The ends of the snap hooks are provided with inwardly protruding hook heads. The snap hooks of the snap claws extend into hook holes at the top corners of the inner cap. The snap hooks of the snap claws extend into the hook holes of the inner cap and are fixed to the snap-fit ​​groove at the bottle mouth by the hook heads at one end of the snap hooks. The top of the snap claws is provided with an elastic disk that, when pressed from the top, causes the snap hooks to deform and expand outward to disengage from the snap-fit ​​groove at the bottle mouth. The center of the elastic disk is provided with an upwardly protruding button column that extends from or is located in the center hole of the outer cap. The inner cap, provided with the snap claws, is inserted into the outer cap, and the outer and inner caps are integrally connected. This cosmetic packaging bottle can be opened with one hand by pressing the button column to cause the snap hooks to deform and disengage from the snap-fit ​​groove, thereby enabling the bottle cap to be opened with one hand. However, this structure relies on the deformation of the claw to engage and disengage the hook from the engaging groove, and the deformation of the hook when the button column is pressed down is unstable. The elastic disk of the claw and the hook are prone to fatigue deformation after long-term use, which will cause the hook to be unable to disengage from the engaging groove normally when the button column is pressed. Summary of the Invention

[0003] The utility model addresses the deficiencies of the existing technology and provides a one-handed opening cosmetic packaging bottle. The one-handed opening cosmetic packaging bottle can effectively prevent the buckle hook from being unable to normally disengage from the buckle groove due to fatigue of the buckle claw after long-term use, effectively improving the stability of the fit between the bottle cap and the bottle body and prolonging the service life.

[0004] In order to solve the above technical problems, the utility model is solved through the following technical solutions: a one-handed opening cosmetic packaging bottle, comprising a bottle body and a bottle cap, the bottle cap comprising an outer cover and an inner cover that are snap-connected, the inner circumference of the bottle cap is provided with a plurality of hooks bent inwardly, the bottle body is provided with a hook groove that cooperates with the hooks, and the plurality of hooks are provided on the inner cover, a movable seat is provided between the outer cover and the inner cover, an elastic reset structure is provided between the movable seat and the inner cover, a pressing port is provided on the top of the outer cover, a plurality of ejector rods are provided on the movable seat, and a plurality of openings for the ejector rods to pass through are provided on the hook head, the ejector rod is aligned with the inner side surface of the hook head, and when the movable seat is pressed down, the ejector rod presses against the inner inclined surface of the hook head to bend the hook head outward to disengage from the hook groove. The one-handed opening cosmetic packaging bottle has a plurality of inwardly bent hooks hooked into the hook grooves to fix the bottle cap and the bottle body. When opening the bottle cap, the movable seat is pressed downward, and the top rod of the movable seat presses the inner side surface of the hook to bend the hook outward to disengage from the hook groove. The operation is convenient, and the deformation of the hook is more stable, ensuring that the hook can be normally disengaged from the hook groove after the movable seat is pressed downward. The service life is longer, the structure is more streamlined, and the manufacturing cost is reduced.

[0005] In the above technical solution, preferably, the elastic return structure includes a guide slope provided on the top of the inner cover, and an elastic rod provided on the bottom of the movable seat, vertically facing the guide slope. This elastic return structure can be directly integrally formed during the production of the inner cover and movable seat, achieving an elastic return effect after assembly, thereby reducing the number of parts such as springs, reducing assembly steps, and lowering assembly and processing costs.

[0006] In the above technical solution, preferably, the guiding slope is a tapered surface that gradually decreases from bottom to top, and the plurality of elastic rods are arranged around the tapered surface with their bottoms aligned with the tapered surface. This structure makes the lateral force when the elastic rods bend more balanced, and is more stable during the lifting and resetting process.

[0015] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments: Figures 1 to 4When the bottle is opened, the bottle cap 2 is opened, and the bottle cap 2 is opened. When the bottle is opened, the bottle cap 2 is opened, and the bottle cap 2 is opened. When the bottle is opened, the bottle cap 2 is opened, and the bottle cap 2 is opened, the bottle cap 2 is opened, and the bottle cap 2 is opened. When the bottle is opened, the bottle cap 2 is opened, and the bottle cap 2 is opened, the bottle cap 2 is opened, and the bottle cap 2 is opened. This single-handed opening cosmetic packaging bottle secures the bottle cap 2 and the bottle body 1 by hooking the inwardly bent hook head 5 into the hook groove 11. When opening the bottle cap, by pressing the movable seat 6 downward, the top rod 61 of the movable seat 6 presses against the inner side surface of the hook head 5 to bend the hook head 5 outward to disengage from the hook groove 11. The operation is convenient, and the deformation of the hook head 5 is more stable, ensuring that the hook head 5 can normally disengage from the hook groove after the movable seat 6 is pressed downward. The service life is extended, the structure is more streamlined, and the manufacturing cost is reduced. When the movable seat 6 is reset, the restoring force of the movable seat 6 comes from the reaction force of the inner inclined surface of the hook head 5 on the top rod 61 and the elastic force of the elastic reset structure 7.

[0016] In this embodiment, the elastic reset structure 7 includes a guide bevel 71 disposed on the top of the inner cover 4, and an elastic rod 72 disposed at the bottom of the movable seat 6, vertically facing the guide bevel 71. This elastic reset structure 7 can be directly integrally formed during the production of the inner cover 4 and the movable seat 6, achieving an elastic reset effect after assembly, reducing the number of parts such as springs that would otherwise be required, reducing assembly steps, and lowering assembly and processing costs. During use, by pressing down on the movable seat 6, the elastic rod 72 is guided by the guide bevel 71, causing it to bend and generate a certain amount of elastic potential energy. When the pressing force on the top of the movable seat 6 disappears, the elastic potential energy in the elastic rod 72 reacts with the guide bevel 71, causing the movable seat 6 to return to its original position.

[0017] Specifically, in this embodiment, the tapered surface is located at the top center of the inner cover 4. The guide slope 71 is a tapered surface that tapers from bottom to top. Four elastic rods 72 are arranged around the tapered surface with their bottoms aligned with the tapered surface. This structure ensures that the lateral force when the elastic rods 72 bend is more balanced, and the lifting and resetting process is more stable.

[0018] In this embodiment, a raised portion 62 is provided on the top of the movable seat 6, which matches the size of the pressing opening 31 and is flush with the surface of the pressing opening 31. This structure makes the raised portion flush with the pressing opening in the closed state, and the appearance is more beautiful.

[0019] In this embodiment, the sidewalls of the outer cover 3 are provided with vertical guide ribs 32, and the movable seat 6 is provided with vertical limiting ribs 63 arranged in groups of two, with the guide ribs 32 located between each group of limiting ribs 63. This structure is used to guide the lifting movement of the movable seat 6, making the movement of the movable seat 6 more stable.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
