The lower end of the inner cap is provided with a force-bearing ring. The upper end of the force-bearing ring is bent inward to form a lower support part. The inner side of the lower support part is bent upward to form an upper support part. The upper support part is fixedly connected to the inner cap. The circumferential surface of the force-bearing ring is provided with several lower flat surfaces. The lower end of the outer cap is provided with a support platform and a snap-fit ​​groove. The middle outer side of the upper support part is provided with a snap-fit ​​ring. The snap-fit ​​ring is inserted into the snap-fit ​​groove. The stable double-layer cap soft tube improves the aesthetics of the tube. The tube is more stable when placed vertically downward. The tube is more substantial and has a better texture, which improves the user experience of cosmetics. It is suitable for use in ointment-like cosmetics such as eye cream and eye ointment.

[0003] The existing technology uses an outer cover, an inner cover, and a tube body. The upper end of the tube body has a tube head, and the side of the outer cover has several upper flat surfaces. The upper end of the tube body has a shoulder, and the lower end of the tube head is connected to the shoulder. The lower end of the tube head has an external thread, and the lower inner end of the inner cover has an internal thread. The lower outer end of the inner cover has a force-bearing ring. The upper end of the force-bearing ring is bent inward to form a lower support, and the inner side of the lower support is bent upward to form an upper support. The upper support is fixedly connected to the inner cover. The circumferential surface of the force-bearing ring has several lower flat surfaces. The lower inner end of the outer cover has a support platform and a snap-fit ​​groove. The middle outer side of the upper support has a snap-fit ​​ring that snaps into the snap-fit ​​groove. This achieves a stable double-layer cap tube, improves the tube's aesthetics, enhances stability when the tube is placed vertically downward, and gives the tube more weight and texture, improving the user experience of cosmetics. It is suitable for use with ointment-like cosmetics such as eye creams and eye balms.

[0004] The existing technology has a pointed structure, which causes the paste to be squeezed out of the outer ring during the gas reflux process in the tube, making it difficult to recover. This leads to the paste solidifying and the outlet becoming blocked.

[0005] Therefore, there is a need for a non-return eye cream tube to improve upon the above-mentioned shortcomings. Utility Model Content
