Description

Technical Field

[0001] The present invention relates to the field of cosmetic packaging, in particular to a cosmetic packaging hose with a discharge control function. Background Art

[0002] Packaging hoses are widely used in cosmetics, daily necessities, pharmaceutical packaging and other fields due to their light weight, ease of use and portability. However, as hoses are soft tubes, they are easily squeezed by external forces during transportation or carrying, causing the material inside the tube to overflow. This not only affects the user experience and appearance of the hose, but also causes material pollution and waste. To solve the above problems, it is necessary to add a device to control the discharge of the material at the hose outlet.

[0003] However, the structural design of such devices currently on the market generally has the problem of cumbersome operation. It is necessary to open the outer cover first and then control the discharge of the material through the device, which is a relatively redundant step.

[0004] Therefore, how to simplify the discharge control process and improve ease of use has become one of the technical problems that need to be solved urgently in this field. Summary of the Invention

[0005] In order to overcome at least one of the above problems, the present invention provides a cosmetic packaging hose with a discharge control function, which has a simple discharge control process and is easy to use.
