Self-suction pump pressure packing bottle discharging pipe

Abstract

The invention relates to a self-suction pump pressure packing bottle discharging pipe. The external contour of the discharging pipe is kept unchanged, and the superficial area of the inner wall of thedischarging pipe is increased. The outer edge of the cross section of the discharging pipe is in a round shape. The discharging pipe is a bent pipe. The bent pipe is composed of a straight pipe A anda straight pipe B. One end of the straight pipe A is a feeding end of the discharging pipe. Increasing the superficial area of the inner wall of the discharging pipe refers to that convex strips arearranged in the discharging pipe. The convex strips are located in the straight pipe A and are straight strips and parallel to a central axis of straight pipe A. The convex strips are arranged in thedischarging pipe in a circumferential mode. The lengths of all the convex strips are same. The centers of the convex strips are located on the same horizontal plane or located on different horizontalplanes. The convex strips and the discharging pipe are obtained through integral forming processing. The self-suction pump pressure packing bottle discharging pipe can meet wall-hanging requirements of thin or low-viscosity paste, the effect is good, the cost is low, the structure is simple, design is reasonable, and the self-suction pump pressure packing bottle discharging pipe has great application prospects.

Description

technical field [0001] The invention belongs to the field of packaging and relates to a self-priming pump pressure packaging bottle discharge pipe. Background technique [0002] With the development of society, people's material life has been greatly enriched. People not only have the pursuit of product quality, but also put forward higher requirements for the appearance and packaging of products, especially the packaging of daily necessities. Its appearance packaging is not only a simple container, but also must take into account the beautiful shape and the convenience of use. Squeeze-type or push-type packaging bottles stand out in the packaging of daily necessities because of their convenience and beautiful appearance. [0003] Patent CN 105923281A discloses a self-priming pump-pressed packaging bottle, which discloses the discharge principle of a general push-type discharge packaging bottle. After the paste is extruded from the discharge pipe, the upper end of the disch...
