Abstract

The utility model provides a saving-type piston packing hose, belonging to the packing technical field. The bottom part of the hose is internally provided with a piston, wherein the internal diameterof the piston is equal to that of the hose, and the piston is coincided with shape of the hose; the top part of the piston is provided with a bulge, wherein the internal diameter of the bulge is equalto that of the mouth of the hose, and the bulge is coincided with the shape of the mouth of the hose; and the bulge is positioned at the mouth of the hose when the piston is pushed to the top part inthe hose. When the hose is used, a hand pushes the piston toward the mouth of the hose from the bottom part of the hose, and the piston is furthermore pushed to the mouth of the hose by the bulge, sothat all residual contents in the hose are squeezed out without any waste, therefore, the saving-type piston packing hose can be widely applied in the fields of daily necessity toothpaste pipes, cosmetic or pharmaceutical packing pipes or packing bottles and the like, and has very high market valve.

Description

Economizing type piston type packaging tube

Technical field

The utility model relates to packaging field, is specifically related to a kind of putty-type packaging tube or Packaging Bottle.

Background technology

Generally putty-type packing device of Shi Yonging such as daily necessities dentifrice tube, cosmetics or pharmaceuticals packaging tube (bottle) etc., when use had been treated, residual content often can't be extruded use in its pipe, so that wastes meaninglessly, has increased use cost, and was very unfortunate.

Summary of the invention

Be to solve the deficiencies in the prior art, the utility model proposes a kind of rational in infrastructure, operation is easy, can make the not remaining piston type packaging tube of paste packaging tube (bottle) content.

For achieving the above object, the utility model is achieved by the following technical programs: economizing type piston type packaging tube includes the pipe lid on packaging tube, the mouth of pipe and the mouth of pipe, described flexible pipe be built-in with in the bottom with inner diameter quite and the piston that coincide with the flexible pipe shape.

The further technical measures of the utility model are, the piston head in stating have with spout diameter quite and the projection of coincideing with orifice configuration, this projection overhead was in the mouth of pipe when piston advanced in flexible pipe to the top.

Described piston is a solid construction, also can adopt hollow structure, and piston length is between 1-5cm.

Compared with prior art, the utlity model has following technical advantage: structure is novel, and is easy to use, cheap, technology is made easily, significantly reduces use cost and resource consumption, applied widely, can be applicable to daily necessities dentifrice tube, cosmetics or pharmaceuticals packaging tube (bottle) etc.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation that piston type packaging tube of the present utility model is applied to dentifrice tube;

Fig. 2 is the structure of piston scheme drawing.

Among the figure: 1, dentifrice tube, 2, packaging tube, 3, the mouth of pipe, 4, Guan Gai, 5, piston, 6, projection.

The specific embodiment

With reference to Fig. 1 and shown in Figure 2, the utility model is applied on the dentifrice tube, this dentifrice tube 1 has flexible pipe 2, the mouth of pipe 3 covers 4 with pipe, dentifrice tube 1 is a cylindrical-shaped structure, and piston 5 is the long solid construction of 3cm, and material can be selected rubber or the strong material of elastic forces such as foam or PVC for use, piston 5 is built in the bottom of flexible pipe 2, its diameter depends on the dentifrice tube size and decides, and only need be slightly less than inner diameter so that can place to get final product in it, and it is shaped as the cylinder that matches with flexible pipe; Piston 5 tops are provided with a projection 6, and similarly this projection 6 is coincide less than the internal diameter of the mouth of pipe 3 and with the mouth of pipe 3 shapes slightly.When using toothpaste, with hand piston 5 is advanced toward the mouth of pipe 3 bottom flexible pipe, remaining toothpaste promptly is extruded in the dentifrice tube, and utilizes projection 6 toothpaste further can be pushed to the mouth of pipe 3, and the interior remaining toothpaste of pipe is all extruded and waste not.

When making the piston type packaging tube, only need after canned toothpaste is finished, putting piston in the dentifrice tube bottom again gets final product, produce easily, use also very convenient, greatly reduce the waste and the consumption of resource, this piston type packaging tube also can be applicable to cosmetics or medical science packaging tube other fields such as (bottles).

According to technique scheme; those skilled in the art according to actual needs; also can design the piston type packaging tube of more different structure forms; but the foregoing description is only enumerated for explanation the utility model; be not to be used to limit the utility model; the structure of any effects equivalent based on the conversion of the technical program institute all belongs to protection domain of the present utility model.

Claims

1, a kind of economizing type piston type packaging tube has the pipe lid on a packaging tube, the mouth of pipe and the mouth of pipe, it is characterized in that: described flexible pipe be built-in with in the bottom with inner diameter quite and the piston that coincide with the flexible pipe shape.

2, economizing type piston type packaging tube according to claim 1 is characterized in that: described piston head have with spout diameter quite and the projection of coincideing with orifice configuration, this projection overhead was in the mouth of pipe when piston advanced in flexible pipe to the top.

3, economizing type piston type packaging tube according to claim 1, it is characterized in that: described piston is solid construction or hollow structure.
