Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural / chemical / medical / food related plastic blow molding packaging bottle structures, and in particular to a blow molding container for hazardous chemicals which can prevent splashing when pouring liquid. Background Art
[0002] The existing hazardous chemicals packaging barrels have a vertical surface directly above the barrel mouth. When the barrel is poured at 45 degrees, the liquid blocks the air in the container, resulting in intermittent spraying of the liquid when pouring, which is easy to cause splashing liquid to contaminate people or objects. The current design on the market to solve this defect is: the barrel body is designed with two bottle mouths, the main bottle mouth is for pouring, and the secondary bottle mouth is relatively small: it is universal for air flow.
[0003] However, this design has an extra set of bottle mouths, which increases the production cost and the risk of leakage. The extra set of bottle mouths has an extra set of sealing processes, which also restricts the aesthetics of the design product. When pouring liquid, an additional opening process is required. For gasoline iron barrels or double-mouth chemical barrels, one of the mouths is used to assist air intake when pouring, so as to achieve pressure balance inside and outside the barrel, and pouring liquid becomes smooth without splashing. The disadvantage of a double-mouth barrel is that it has an extra mouth, an extra cover, and an extra possibility of leakage. Summary of the invention
[0004] The utility model mainly solves the deficiencies in the prior art and provides a blow-molded container for hazardous chemicals that prevents splashing when pouring liquids. The container has the characteristics of simple structure, good pouring flow rate stability and high safety and sealing. The problem of splashing or unstable flow rate caused by pressure fluctuations when pouring solutions is solved. The pressure difference between the inside and outside of the container is balanced by the structure of supplementing air, which has the effect of stabilizing the flow rate and preventing splashing.
[0005] The above technical problems of the utility model are mainly solved by the following technical solutions:
[0006] A blow-molded container for hazardous chemicals that can prevent liquid from splashing when poured, comprises a blow-molded container barrel body, a handle is provided at the upper end of the blow-molded container barrel body, a pouring spout is provided on one side of the handle and is integrally connected to the blow-molded container barrel body, a barrel cover is provided on the pouring spout and is threadedly sleeved on the pouring spout, a guide block is provided in the pouring spout, and the guide block is provided with one or more air replenishment channels that are connected to the blow-molded container barrel body.
