Technical Field

The invention relates to a liquid storage bottle, in particular to a liquid storage bottle with a vacuum pump, and belongs to the field of packaging containers. The invention also relates to a die, belongs to the field of molding, and also relates to a manufacturing method, belonging to the field of industrial manufacturing.

Background

The liquid storage bottle with the vacuum pump is one of the most common storage containers for a plurality of emulsion liquids on the market, and the vacuum pump is manually compressed, so that the use is very convenient.

Every time the vacuum pump is pressed, a certain amount of storage liquid can be discharged from the pump outlet, and waste is avoided. However, when the liquid in the liquid storage bottle of the vacuum pump is used to the end, the liquid outlet pipe of the vacuum pump is not in a full-covering state, so that part of the liquid is remained.

The drain pipe bottom of present vacuum pump has several kinds of forms, one kind is the flat notch, and the drain pipe of flat notch generally makes the drain pipe bottom apart from the certain distance of body when setting up, guarantees that the drain pipe can inhale liquid, and consequently remaining liquid volume is just the liquid of drain pipe bottom to this height of body bottom.

The other mode is a bevel cut, the beveled bottom end of the liquid outlet pipe can be contacted with the bottom surface of the bottle body, when the beveled pipe opening can be contacted with air, the amount of liquid extracted by the vacuum pump begins to be reduced, when the liquid descends again, the vacuum pump can hardly extract the liquid again, and the amount of the residual liquid depends on the bevel inclination of the liquid outlet pipe.

Therefore, although the two methods can reduce certain liquid residue, a part of the liquid remained in the liquid storage bottle cannot be drawn out, if the liquid is directly thrown away, part of the liquid is wasted, and if the liquid is directly poured out from the bottle mouth after being opened, the using amount is not well controlled.

There are some methods to solve the problem, for example, CN201711252640.1 discloses a method of adding a weight on the bottom of the liquid outlet pipe, but this method causes inconvenience when in use, and when the liquid is about to be used up, the liquid storage bottle needs to be tilted for use, and if some liquid with relatively high viscosity is used, the tilted state needs to be kept for a long time, which further reduces the user experience.
