Description

Bottom Filling Vented Liquid Bottles

technical field

The utility model relates to the field of liquid packaging, in particular to a bottom-filled and vented liquid bottle.

Background technique

Liquid spray bottles are widely used in various industries and technical fields, such as cosmetics, medicine, food and other fields. After the liquid in the liquid spray bottle is used up, the bottle body is usually discarded, resulting in waste of resources and environmental pollution. After the bottle is opened, if people need to travel and use it, they need to re-tighten the spray bottle. During the tightening process, the bottle cap needs to be squeezed, which will easily cause the liquid in the bottle to flow out. Usually the original bottle is large and inconvenient to carry .

Contents of the invention

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a bottom-filled and vented liquid bottle. The technical solution adopted by the utility model to solve the technical problem is: the structure of the utility model includes a bottle body , piston, liquid filling port, sealing ring, filling hole, spring, vent hole, exhaust cavity, piston sleeve, exhaust port, upper exhaust pipe, filling pipe, which is characterized in that the center position of the bottom of the bottle is set There is a piston sleeve, which is integrated with the bottle body. The piston sleeve is arranged in the inner cavity of the bottle. There is an exhaust port inside the piston sleeve. The cavity between them is the exhaust cavity, and the outer side of the piston is surrounded by a sealing ring, which can prevent liquid leakage during filling and storage. There is a liquid filling port at the bottom of the piston, which is connected to the filling pipe. The top of the filling pipe is provided with a filling hole, the piston is provided with an upper exhaust pipe, and the upper exhaust pipe is provided with an exhaust hole, the end of the spring is arranged at the bottom of the piston, and the top of the spring is arranged at the inner side of the piston sleeve .

Working principle: After removing the nozzle of the large liquid bottle at home, there is a thin tube, align the base of the bottle body with the thin tube of the large liquid bottle, connect the liquid filling port with the thin tube, press down on the bottle body, Under the action of force, the spring is compressed, the piston is pushed up, and the large bottle of liquid flows into the filling pipe from the filling port, and finally injects into the inner cavity of the bottle through the filling hole. When the piston moves up, the air in the inner cavity of the bottle is squeezed due to the liquid injection and the upward movement of the piston. At this time, the exhaust hole on the upper exhaust pipe coincides with the exhaust port, and the air in the inner cavity of the liquid bottle passes through the upper exhaust pipe and flows through the The exhaust hole flows into the exhaust cavity through the exhaust port, and finally discharges out of the bottle from the gap between the liquid filling port base and the piston sleeve.

The beneficial effects of the utility model are: the filling pipe and the exhaust pipe are integrated on the piston, the structure is simple, the assembly is convenient, and it is beneficial to quantitative production; multiple sealing rings are used between the piston and the piston sleeve to effectively ensure that the liquid in the bottle does not leak out ; Can be used in many fields, easy to market, small size, easy to carry and store.

Detailed ways

The utility model is described in detail below with reference to the accompanying drawings. As shown in the drawings, the structure of the utility model includes a bottle body 1, a piston 2, a liquid filling port 3, a sealing ring 4, a filling hole 5, a spring 6, an exhaust hole 7, an exhaust cavity 8, and a piston sleeve 9 , an exhaust port 10, an upper exhaust pipe 11, and a filling pipe 12, which are characterized in that a piston sleeve 9 is arranged at the center of the bottom of the bottle body 1, and the piston sleeve 9 and the bottle body 1 are integrally shaped, and the piston sleeve 9 is arranged on the bottle body 1 In the inner cavity, an exhaust port 10 is arranged on the inner side of the piston sleeve 9. The exhaust port 10 is trapezoidal in shape, and the piston sleeve 9 is provided with a piston 2, and the cavity between the piston sleeve 9 and the piston 2 is an exhaust cavity 8. The outer side of the piston 2 is surrounded by a sealing ring 4, and the bottom of the piston 2 is provided with a liquid filling port 3. The liquid filling port 3 communicates with the filling pipe 12.
