Abstract

The utility model provides a packaging plastic flexible tube with sealing lines, wherein a concave line and a convex line are provided correspondingly on the two sides of inner wall of the hose and are sealed with each other. When in use, the concave line and the convex line are engaged with each other as the pasty material inside the hose is extruded out, so as to attach the two sides of the inner wall. The utility model prevents the flexible tube from returning to the original shape upon elasticity, controls the flow direction of the pasty material inside the flexible tube, avoids the repeated extrusion when being reused, and facilitates the daily life of people. The utility model has the advantages of simple structure and easy use.

Description

A kind of inwall has the plastic wrapping flexible pipe of involution line

The utility model relates to a kind of later-model plastic wrapping flexible pipe, and especially a kind of inwall has the plastic wrapping flexible pipe of involution line.

Existing plastic wrapping flexible pipe is used for food, toothpaste more, washes clean article and cosmetics etc., plastic hose is compared with the flexible pipe of lead system or aluminum, though use good hand touch, easily produce, but its shortcoming is because of the strong poor plasticity of its elasticity, so after extruding, can restore to the original state, make the not flow direction control preferably of paste object in the body, all to push repeatedly during each the use, the paste object could be expressed to the exit of flexible pipe, bring some inconveniences for people's life.

The purpose of this utility model provides and a kind ofly at hose inner wall the involution line is set, and the inwall that can fasten mutually after the extruding has the plastic wrapping flexible pipe of involution line, can solve the inconvenience that plastic wrapping flexible pipe elasticity is brought to use greatly preferably.

The utility model is achieved in that by body and end cap to be formed, and a side of inboard wall of tube body has some concaves, and the opposite side of inwall has some and the corresponding convex line of concave, and concave and convex line can fasten mutually, and the both sides of inwall are pasted mutually.

The concave of inwall one side is a strip, its section be shaped as the U font, vertically be connected in a side of inboard wall of tube body; The convex line of inwall opposite side is a strip, its section be shaped as the tenon shape, vertically be connected in opposite side with the corresponding inwall of concave.

Concave and convex line can the segmentation settings, the corresponding respectively both sides that vertically are connected in inboard wall of tube body.

The utlity model has following advantage:

1. simple in structure, easy to use;

2. need not to push repeatedly during because of use, bring convenience to daily life.

Accompanying drawing 1 is external form figure of the present utility model;

Accompanying drawing 2 is the utility model generalized section;

Accompanying drawing 3 is the generalized section after the utility model extruding.

Wherein: 1 convex line, 2 concaves, 3 inwalls, 4 bodys, 5 paste objects, 6 end caps

Be described further below in conjunction with accompanying drawing:

As shown in Figure 2, a side of inboard wall of tube body 3 has some concaves 2, its section be shaped as the U font, vertically be connected in a side of inboard wall of tube body 3; Inwall 3 opposite sides have some with concave 2 corresponding convex lines 1, its section be shaped as the tenon shape, vertically be connected in the opposite side with concave 2 corresponding inwalls 3, concave 2 and convex line 1 can fasten mutually, and the both sides of inwall 3 are pasted mutually.

Concave 2 and convex line 1 can be divided into several sections, the corresponding respectively both sides that vertically are connected in inboard wall of tube body 3.

When paste object 5 pours into packaging tube, open end cap 6 in use, push body 4 from bottom to up, paste object 5 is extruded from the mouth of pipe, this moment, corresponding concave 2 and convex line 1 fastened mutually, and the inwall 3 of body 4 both sides is pasted (as shown in Figure 3) mutually.Body 4 no longer restores to the original state because of its elasticity, and the paste objects 5 in the body 4 are squeezed on the top of body 4, have overcome the original elasticity of plastic hose, makes the paste objects 5 in the body 4 can be directionless mobile body 4 in.Along with being extruded of paste object 5, the concave 2 of inwall 3 both sides and convex line 1 fasten to body mouth of pipe place gradually, are extruded fully up to paste object 5.During each the use, need not to push repeatedly again body 4, bring convenience for people's life.

The concave 2 of inboard wall of tube body 3 both sides and convex line 1 can also the segmentation setting, vertically is connected in the both sides of inwall 3 respectively accordingly.

Claims

1. an inwall has the plastic wrapping flexible pipe of involution line, comprise body and end cap, its special card is that a side of inboard wall of tube body has some concaves, and the opposite side of inwall has some and the corresponding convex line of concave, concave and convex line can fasten mutually, and the both sides of inwall are pasted mutually.

2. a kind of inwall according to claim 1 has the plastic wrapping flexible pipe of involution line, the concave that it is characterized in that inwall one side is a strip, its section be shaped as the U font, vertically be connected in a side of inboard wall of tube body, the convex line of inwall opposite side is a strip, its section be shaped as the tenon shape, convex line vertically is connected in the opposite side with the corresponding inwall of concave.

3. a kind of inwall according to claim 1 has the plastic wrapping flexible pipe of involution line, it is characterized in that concave and convex line can the segmentation settings, the corresponding respectively both sides that vertically are connected in inboard wall of tube body.
