Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging, and more specifically, to a face cream jar. Background Technology

[0002] As a common cosmetic packaging container, the design of a face cream jar plays a key role in protecting product quality, ensuring airtightness, and facilitating consumer use. A face cream jar typically includes a container body, a screw-on cap, and an outlet for applying face cream.

[0003] Traditional face cream jar designs typically rely on threaded structures to tighten and seal the cap. During the tightening process, the preload generated between the threads restricts the rotation of the cap and ensures a tight seal. However, existing face cream jars only have sufficient preload to restrict the rotation of the cap when fully tightened. When the cap is not fully tightened, it is easy for the cap to loosen or even fall off. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a face cream jar.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a face cream jar, including a jar body and a screw cap, wherein a threaded section that mates with the screw cap is fixedly connected to the top of the jar body, and a plurality of slots are provided on the top surface of the threaded section, wherein an elastic block is provided in the slot, the top surface of the elastic block is higher than the top surface of the threaded section, and the elastic block abuts against the screw cap.

[0006] The present invention is further configured such that a gap is provided between the inner wall of the slot and the elastic block.

[0007] The present invention is further configured such that the cross-sectional area of ​​the bottom end of the slot is greater than the cross-sectional area of ​​the top end of the slot.

[0008] The present invention is further configured such that the cross-sectional area of ​​the bottom end of the elastic block is greater than the cross-sectional area of ​​the top end of the slot.

[0009] The present invention is further configured such that the inner top surface of the screw cap is a horizontal plane.

[0010] In summary, this utility model has the following beneficial effects: by applying an upward force to the cap through the elastic block, the pressure between the threaded section and the cap increases, thereby improving the preload between them. This ensures that the preload between the cap and the threaded section no longer relies entirely on the compression between the cap and the can after tightening, thus guaranteeing the connection strength and sealing performance between the cap and the can. Both the can and the threaded section are made of HDPE material, giving them good rigidity and ensuring the structural stability of the slot and the threaded section. Attached Figure Description

[0014] In the diagram: 1. Tank body; 2. Screw cap; 3. Threaded section; 4. Slot; 5. Elastic block. Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Example: A face cream jar, such as Figures 1-3 As shown, it includes a can body 1 and a screw cap 2. The top of the can body 1 is fixedly connected to a threaded section 3 that mates with the screw cap 2. Several slots 4 are provided on the top surface of the threaded section 3. An elastic block 5 is provided in the slot 4. The top surface of the elastic block 5 is higher than the top surface of the threaded section 3. The elastic block 5 abuts against the screw cap 2. The inner top surface of the screw cap 2 is a horizontal plane.

[0017] Specifically, the threaded section 3 is integrally formed with the can body 1, the cap 2 is threadedly engaged with the threaded section 3, and there are four slots 4. The threaded section 3 accommodates the rubber elastic block 5 through the slots 4. When the cap 2 rotates downward on the threaded section 3, the cap 2 squeezes the elastic block 5, forcing the elastic block 5 to deform. After the rotation of the cap 2 is completed, the elastic block 5 applies an upward force to the cap 2, which increases the pressure between the threaded section 3 and the cap 2, and improves the pre-tightening force between them. This means that the pre-tightening force between the cap 2 and the threaded section 3 no longer relies entirely on the squeezing between the cap 2 and the can body 1 after tightening, ensuring the connection strength and sealing between the cap 2 and the can body 1. At the same time, the inner top surface of the cap 2 is parallel to the bottom surface of the elastic block 5, ensuring that the force applied by the elastic block 5 to the cap 2 tends to be vertically upward. Both the can body 1 and the threaded section 3 are made of HDPE material, which gives the can body 1 and the threaded section 3 good rigidity and ensures the structural stability of the slots 4 and the threaded section 3.

[0018] like Figures 1-3As shown, there is a gap between the inner wall of the slot 4 and the elastic block 5. The cross-sectional area of ​​the bottom of the slot 4 is larger than the cross-sectional area of ​​the top of the slot 4, and the cross-sectional area of ​​the bottom of the elastic block 5 is larger than the cross-sectional area of ​​the top of the slot 4. Specifically, the bottom area of ​​the slot 4 is larger than the bottom area of ​​the elastic block 5, which creates a gap between the inner wall of the slot 4 and the elastic block 5. This provides space for the deformation of the elastic block 5 and prevents the cap 2 from not being able to be screwed in completely. Both the slot 4 and the elastic block 5 have a structure that is smaller at the top and larger at the bottom. The gap between the top of the slot 4 and the elastic block 5 is smaller, which makes it easier for the top of the elastic block 5 to tend to be vertical so that the elastic block 5 can press the cap 2 upward. The bottom cross-sectional area of ​​the elastic block 5 is larger to prevent the elastic block 5 from coming out of the slot 4.

[0019] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
