Description

Package for preventing content from automatic flowing out

Technical Field

The invention relates to the technical field of packaging, in particular to a package capable of preventing contents from automatically flowing out.

Background

The invention discloses a method for completely extruding ointment, and relates to an ointment bag capable of completely extruding ointment, wherein the ointment bag comprises a conventional ointment bag 1, a cylinder 2, a column core 3 and air holes 4, the cylinder is placed at the bottom of the ointment bag, the column core is positioned in the center of the cylinder and can move up and down, when the ointment cannot be extruded out, the air holes are torn, the cylinder is upwards extruded and pushed, the ointment in the ointment bag can be extruded, and the residual ointment in an ointment opening is extruded by pushing the column core, so that no residue is left, no waste is caused, and the ointment is saved and environment-friendly. By the same method, toothpaste bags, toothpaste cosmetic bags and other toothpaste article packaging bags with the same functions can be manufactured. However, in practical use, on one hand, the cylinder itself is difficult to push, and on the other hand, the cylinder is not reset after being pushed, so that the problem that the content automatically flows out due to the fact that the external pressure exerts force on the content due to the deformation of the ointment bag is easily caused.

Also, an invention of patent publication No. CN204323924U is a push toothpaste package, comprising a barrel, a toothpaste nozzle, and a piston; wherein: the tube body is hollow and cylindrical, the top end of the tube body is provided with a toothpaste nozzle, and the bottom end of the tube body is open; the piston is arranged in the cylinder body and is a disc-shaped piston, the circumferential side wall of the piston is in sliding fit with the inside of the cylinder body, and the piston can vertically slide in the cylinder body along the inside of the cylinder body under the action of external force. When the push toothpaste package provided by the invention is used, the toothpaste can be completely squeezed out, no waste is caused, and the push toothpaste package is very convenient to use. However, in actual use, the piston still cannot be reset after being pushed, and the problem that the content flows out automatically due to the fact that the external pressure exerts force on the content due to the deformation of the cylinder body still exists.

In conclusion, the object containing the contents is extruded and then stands still, and the external pressure applied to the contents due to the deformation of the object body is easy to cause the contents to automatically flow out, so that the waste is caused, and the extrusion pushing mode is labor-consuming and inconvenient to use.

Therefore, in order to solve the technical problems, the invention provides a package for preventing contents from automatically flowing out, which solves the problem that the contents are not used completely in the prior art on one hand, and controls the pressure by controlling the size of an inner storage cavity in the package on the other hand, so that the contents are not pressed any more and automatically flow out.
