Abstract

The utility model relates to a plastic toothpaste tube with double-layer structure, wherein, the inner layer is provided with a plastic film bag, the outer layer is provided with a plastic outer shell with elastic restoring force, and a sandwich layer space between the inner layer and the outer layer is communicated with atmospheric air by small air through holes on an outer shell. An inner bag of the toothpaste tube is used for storing toothpaste; after the toothpaste is extruded, the volumn of the inner bag is reduced; when the outer shell reverts to original shape, negative the pressure can be generated in the sandwich layer; then, the outer shell sucks air from the through holes, which keeps the appearance of the toothpaste tube to be unchanged. The utility model has the advantages that the operation is convenient, and the toothpaste which is extruded from the outer paste tube of the utility model does not generate the inverse sucking phenomenon. The utility model can replace the outer paste tube made of aluminum, which lowers the cost and saves a large numbers of aluminum materials.

Description

Plastic toothpaste tube

The utility model is a dentifrice tube of storing cream and crowded cream about a kind of, is fit to all body of paste and uses.

Dentifrice tube adopts metallic aluminium to make more, cost height, and the aluminium of consume valuable.As adopt plastics to replace the aluminum dentifrice tube, and can save aluminium, for example the external used medicine of existing paste adopts plastics cream pipe mostly.This cream pipe makes the lotion of extruding easily by in the suck-back return pipe because the elastic recovery effect of plastics produces negative pressure, also because increasing of pipe internal pore often can only be extruded air, is difficult to extrude lotion, causes residual lotion all not extrude utilization, causes waste.

It is effective that the purpose of this utility model provides a kind of crowded cream, and the plastics dentifrice tube of no suck-back is to save aluminium, cost-cutting.

The utility model plastics dentifrice tube is made up of plastic sheeting inner bag and the plastic casing with restoring force, and inner bag is store cream and communicated with paste outlet, forms interlayer between shell and the inner bag, and this interlayer communicates with atmosphere by the air bleeder on the shell.

Can pin spilehole with finger when the utility model uses, push shell simultaneously, make internal layer storage cream bag uniform-compression, extrude toothpaste from paste outlet, point when decontroling, when eliminating squeese pressure, shell reinstatement owing to elastic force produces negative pressure in the interlayer simultaneously, and air charges into interlayer by pore.Because the plastic sheeting inner bag do not have return action, thereby inner bag do not have negative pressure, and lotion can be by suck-back.Along with the minimizing of inner bag lotion, the space of interlayer increases gradually, but the profile of shell is constant.

As seen, the utility model plastics dentifrice tube has overcome the shortcoming of existing plastics storage cream pipe lotion suck-back, and tight in the storage cream bag is extruded lotion easily, and it is crowded clean to be convenient to residual lotion, with its dentifrice tube that replaces aluminum, can save aluminium, cost-cutting.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the front elevation of these plastics dentifrice tube.

Fig. 2 is the birds-eye view of Fig. 1.

As Fig. 1, Fig. 2, the utility model is made up of the plastic casing 3 of plastic sheeting inner bag 4 and flexible restoring force, and inner bag links to each other with paste outlet 2 together with shell, and inner bag communicates with paste outlet, form interlayer 5 between the inside and outside layer, this interlayer communicates with atmosphere by the air bleeder on the shell 6.

The effective common process of these plastics toothpaste is made, and covers cap 1, and cream outside the inside packed filling of afterbody is then with the afterbody hot pressing sealing in the lump of shell.

Claims

The plastics dentifrice tube is characterized in that being made up of plastic sheeting inner bag and plastic casing with elastic-restoring force, and inner bag communicates with paste outlet, and and shell between form interlayer, this interlayer communicates with atmosphere by the air bleeder on the shell.
