Abstract

The utility model discloses a double piston toothpaste cylinder, which relates to a toothpaste cylinder used for dishing and extruding a toothpaste body and is composed of a cylinder body, the head of the cylindrical body, an upper piston, a lower piston and a nozzle head. The center of the head of the cylindrical body is provided with an inner pipe whose both ends are provided with openings; the lower piston and the upper piston are separately mounted in the cylinder body and the inner pipe of the head of the cylindrical body, an upper piston rod is a circular pipe whose both ends are provided with openings; the nozzle head is arranged at the top part of the head of the upper piston. When the nozzle head is pressed by a hand to make the upper piston go down, the toothpaste body in the inner pipe of the head of the cylindrical body is extruded out from a toothpaste outlet mouth at one side of the top part of the nozzle head through a one-way valve; when the upper piston resets under the action of a spring, the inner part of the inner pipe of the head of the cylindrical body forms negative pressure, the lower piston moves up, and the toothpaste body in the cylindrical body is pressed into the inner pipe of the head of the cylindrical body through the one-way valve.

Description

The dual Piston toothpaste tube

The utility model relates to a kind of toothpaste tube that is exclusively used in splendid attire and extrudes toothpaste body.

Toothpaste is requisite necessity in people's daily life, be generally paste body shape and can in toothpaste tube so that carry and use.Toothpaste tube of the prior art is soft toothpaste tube and the direct hand pinching cream that passes through that adopts metal skin or plastics to make mostly.Because soft toothpaste tube intensity difference, yielding, bring a lot of difficulties not only for the manufacturing of toothpaste tube and the can of lotion, and give toothpaste carry and use brings some inconvenience.Particularly, soft toothpaste tube is poor to the comformability of pasty consistence, and crowded cream amount is also wayward.

The purpose of this utility model promptly is the improvement in addition suitable to the structure of toothpaste tube, makes it to be more convenient for carrying and using, and makes it to adapt to the toothpaste body of various different denseness simultaneously and is convenient to control the cream amount of squeezing.

To achieve these goals, to change soft cylindrical shell be the hard cylindrical shell with higher-strength to the utility model.Simultaneously, design one cover is made of barrel head, upper piston, lower piston and nozzle head and the double-piston of working in coordination with cylindrical shell squeezes cream mechanism.Barrel head is installed in the top of cylindrical shell, and its central authorities have the interior pipe of both ends open; Lower piston and upper piston are installed in cylindrical shell and the interior pipe of barrel head respectively and can slide up and down therein, and upper piston rod is the pipe of both ends open, and its top has a upper piston head; The nozzle head is installed in the upper piston head and works in coordination with the upper piston head.When making upper piston descending by hand by the nozzle head, the toothpaste body of storing in the pipe in the barrel head is chewed and is extruded from the cream that goes out of the first side of nozzle through upper piston rod and check valve.During horizontal reset, form negative pressure in the pipe in the barrel head under the effect of upper piston at spring force, lower piston is subjected to the barometric pressure effect up and the toothpaste body in the cylindrical shell is standby in the pipe in check valve is pressed into barrel head.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model dual Piston toothpaste tube.

Accompanying drawing 1 is the structural representation of the utility model dual Piston toothpaste tube;

With reference to the accompanying drawings 1, the utility model dual Piston toothpaste tube mainly is made of cylindrical shell, barrel head, upper piston and lower piston and nozzle head.Cylindrical shell 1 is a cylindrical shape, and the top has paste outlet and has a check valve 2, and the bottom has induction opening.Lower piston 3 is cylindrical, is installed in the cylindrical shell 1 also can slide up and down therein.Barrel head 4 is the cylindrical shape of upper end open, is installed in the top of cylindrical shell 1, and its central authorities have the interior pipe 5 of both ends open, the interior pipe 5 outer springs 6 that are set with, and the lower end of interior pipe 5 is communicated with cylindrical shell 1 by check valve 2.Upper piston 7 is cylindrical, be installed in the barrel head in the pipe and can slide up and down therein, its piston rod 8 is the hollow circular tube of both ends open, the top of piston rod 8 have with barrel head in the pipe medi-spring 6 upper piston head 9 of working in coordination, the check valve 10 that also has suitable for reading of piston rod 8.Nozzle head 11 is the cylindrical shape of lower ending opening, is installed in the top of upper piston head 9 and works in coordination with upper piston head 9, and its lower end is communicated with upper piston rod 8 by check valve 10, and its top one side has out cream and chews 12.

The structure of check valve 2 and check valve 10 is basic identical.Be annular arrangement, make by nonrigid plastic, its central authorities have and are used for capping cylinder top paste outlet or upper piston rod circular closure suitable for reading, and the below of capping has can insert the cylinder top paste outlet or the upper piston rod axis of guide suitable for reading, and the section of the axis of guide is a criss-cross.

The toothpaste body can in cylindrical shell lower piston above.When squeezing cream, press the nozzle head by hand and make upper piston descending, be stored in the barrel head toothpaste body in the pipe and promptly go out cream from the nozzle head and chew and extrude through upper piston rod and check valve.When unclamping hand, upper piston horizontal reset under the effect of spring force forms negative pressure in the pipe in the cylindrical shell, and the lower piston of cylindrical shell is up and be pressed into barrel head in pipe standby by paste outlet and check valve the toothpaste body in the cylindrical shell under the barometric pressure effect.

The utility model novel structure, cylindrical shell are not yielding, easy to carry and use, squeeze the cream amount and can strictly control the also lotion of applicable different denseness.The utility model also can be used for splendid attire and extrudes shoe polish, shampoo, bath foam, lubricated wet goods similar articles except that being particularly suitable for as the toothpaste tube.
