Container anti-overflow method and anti-overflow container

Abstract

The invention discloses a container anti-overflow method and an anti-overflow container. The container comprises a liquid outlet formed in the upper end and is used for preventing liquid in the container from directly flowing out of the liquid outlet when the container is inverted, after the container is inverted, the liquid flowing to the liquid outlet is intercepted firstly, during the process of the liquid flowing to the liquid outlet, the space in the container at the rear end of the liquid outlet is gradually filled, part of air in the container is discharged from the liquid outlet, external air is prevented from entering the container from the liquid outlet, so that the gas outside the P container minus the gas inside the P container is greater than or equal to the liquid inside theP container before the liquid reaches the liquid outlet, non-automatic overflow of the liquid is realized, the tension of the liquid, an independent cavity and a narrow liquid channel are utilized tocontrol the outflow of the liquid, and the flow rate and outflow amount of the liquid depend on the extrusion degree of a user to the container on the premise of sufficient liquid; and under the statethat the flow rate and the outflow amount are controlled, the user can use a proper amount of liquid in different scenes, and the self-effect of the liquid is fully played.

Description

technical field [0001] The invention relates to the technical field of packaging devices, and more specifically, to a container overflow prevention method and an overflow prevention container. Background technique [0002] Existing liquid packaging containers generally use pouring or inversion to make the liquid flow out, but whether this type of liquid packaging container is in use or in a shelf state, once it is poured or inverted, the liquid will flow out automatically; in the use state, the container Once it is poured or turned upside down, the liquid will overflow automatically, and the flow process of the liquid cannot be controlled. In this process, the liquid itself is not only wasted, but also operation inconvenience is brought to the user. For this reason, in the prior art, a spiral liquid flow channel is designed, which can delay the outflow of the liquid when the container is toppled or inverted, but this type of flow channel still cannot solve the problem of aut...

[0002] Existing liquid packaging containers generally use pouring or inversion to make the liquid flow out, but whether this type of liquid packaging container is in use or in a shelf state, once it is poured or inverted, the liquid will flow out automatically; in the use state, the container Once poured or inverted, the liquid will automatically overflow, and the flow process of the liquid cannot be controlled. In this process, not only the liquid itself is wasted, but also the operation inconvenience is brought to the user.

For this reason, in the prior art, a spiral liquid flow channel is designed, which can delay the outflow of the liquid when the container is toppled or inverted, but this type of flow channel still cannot solve the problem of automatic overflow of the liquid. will flow out of the container

[0003] The flow control of liquid is even more important in the use of daily necessities, especially in plastic packaging containers that store low-viscosity liquids, such as liquid detergents, personal care products, liquid flavorings, etc.; because the container liquid is prone to automatic overflow Therefore, it often happens that the user overflows the liquid before the liquid outlet of the container is aimed at the target object, which not only causes waste of liquid, but also easily leads to improper dosage

For the target object that needs to control the amount of liquid, even if the liquid outlet of the container is aligned with the target, when the container containing the liquid is tipped or inverted, it will be difficult for the user to control the outflow of the liquid due to the gravity of the liquid and the instantaneous impact force. Effective control; combined with the automatic overflow situation, the liquid is prone to a large amount of overflow after the container is tipped or inverted, that is, the outflow of the liquid is often uncontrollable during use, and the amount of too much or too little liquid will be significant It affects the use effect of the liquid itself, so that the use effect of the liquid cannot be optimal, so it is very important to realize the flow process control of the liquid

In addition, in the state of shelving, such daily necessities are generally placed in a position that is easy for users to touch, and is also a position that is easy to be overturned or dumped. When the user does not seal it, once the container is tipped over, it will splash on the ground , in addition to wasting liquid, there may be dangerous accidents due to the lubricity of the liquid itself
