Inner cap assembly convenient to use

Abstract

The invention discloses an inner cap assembly convenient to use. A reset structure is arranged in an inner cavity of a seal sleeve; when the upper end of a liquid discharge pipe sleeve suffers an external force so as to jack the rest structure, and the external force is removed, the reset structure automatically jacks the liquid discharge pipe sleeve to reset, so that a first liquid inlet and a second liquid inlet are in a staggered sealed plugging state switched from an aligned conducting state; meanwhile, a liquid discharge control valve capable of being opened along with the inclining of the liquid discharge pipe sleeve is arranged at a position, located between a liquid outlet and the second liquid inlet, in a liquid discharge cavity; and when in use, the external force is needed to act on the liquid discharge pipe sleeve so as to align and conduct the first liquid inlet and the second liquid inlet, and meanwhile, a container and the liquid discharge pipe sleeve need to be inclined. Therefore, by adopting the technical scheme provided by the invention, the overall inner cap assembly is ensured to be at a sealed state before and after use, is low in cost due to a concise structure and less parts, is convenient to operate since the inner cap assembly is opened by utilizing the rest structure or automatically closed, and has the characteristic of smoothness in discharging liquid at the same time.

Description

【Technical field】 [0001] The invention relates to a container cover, in particular to a convenient inner cover assembly. 【Background technique】 [0002] Corresponding to some packaging such as containers, it needs to use an inner cover, that is, install the inner cover at the mouth of the container and then connect the outer cover. In the prior art, there is an inner cover / plug directly made of silica gel. However, when using this structure, the inner cover / plug needs to be removed. During the process of removing the inner cover / plug, the user will inevitably touch the container mouth Part and solution, for this reason, there is the defect of inconvenient use and unhygienic. [0003] In addition, there is an inner cover structure, which is formed by connecting multiple components, but it has the defects of high assembly and manufacturing costs, poor liquid outlet effect during use, and unsatisfactory sealing effect after use. [0004] For this reason, how to provide an inn...
