Abstract

The utility model discloses a volume-preset toothpaste tube, which comprises a cylindrical tube body having an upper cover and a bottom. The lower part of the bottom is provided with a base having a threaded rod and a positioning bulge, wherein the threaded rod axially passes through the inner cavity of the tube body from the bottom so as to be threaded to a piston in the tube body, and a plurality of positioning holes corresponding to the positioning bulge are arranged on the bottom. When using, the base on the lower part of the tube body is rotated in order to move the piston upwards along the screw thread on the threaded rod and extrude the toothpaste in the inner cavity from an outlet. Meanwhile, the positioning bulge on the base is matched with the positioning holes on the bottom so the toothpaste is extruded with a preset volume at each time for completely eradicating the over-extruding phenomenon, which not only decreases the waste of toothpaste but also prevents the harm to human body caused by overusing the toothpaste, therefore being fit for children. The threaded rod axially passes through the inner cavity of the tube body, so the piston can move upwards to the top of the inner cavity along the threaded rod so as to completely extrude the toothpaste, reduce the residual quantity and prevent wastage.

Description

The quantitative dentifrice tube

One, technical field

The utility model belongs to the daily necessities technical field, is specifically related to a kind of quantitative dentifrice tube.

Two, background technology

Toothpaste is the necessity of daily life, is made of flexible pipe that has lid and interior lotion thereof usually.During use, the lid of outwarding winding directly squeezes at toothbrush and gets final product, and is very convenient.But the extrusion capacity of this kind toothpaste can only artificially be controlled, much more very easily to squeeze, and relatively poor children of control ability particularly, to squeeze phenomenon more serious more.Like this, not only cause the waste of toothpaste, excessive use toothpaste also can cause the harm of health, and particularly the toothpaste with fluoride problem is more serious.According to media report, Shanghai City relevant departments res shows that toothpaste dosage was too much when most children brushed teeth, and caused fluorine content severe overweight in blood and the urine.

Three, summary of the invention

The purpose of this utility model provides a kind of simple in structure, reasonable in design, can control the toothpaste extrusion capacity effectively, reduces the toothpaste waste, avoids causing the quantitative dentifrice tube of health harm.

For achieving the above object, the technical solution adopted in the utility model is: this dentifrice tube comprises the cylindrical tube that has loam cake and manage the end, be characterized in: the bottom at the pipe end is provided with the base of threaded shank and positioning convex, and thread rod penetrates from the pipe end axially through tube cavity and with piston thread in the body and is connected; Be provided with positioning convex corresponding positioning hole on several and the base on the end at pipe.

Adopt said structure, the lotion of packing in the tube cavity on piston top.During use, the base of rotation body bottom makes piston along moving on the screw thread on the thread rod, and lotion in the inner chamber is extruded from outlet.Simultaneously, the positioning convex on the base cooperatively interacts with the knock hole of pipe at the end, and making at every turn can only be according to quantitatively extruding, the generations of squeezing phenomenon have fundamentally been stopped more, not only reduced the waste of toothpaste, the health of also having avoided causing because of excessive use toothpaste endangers, and is particularly suitable for children and uses.Because thread rod axially through tube cavity, makes piston to make lotion all to be extruded along the top that moves to tube cavity on the thread rod, has reduced residual quantity, has avoided waste.The utility model is simple in structure, reasonable in design, has replenished the blank of this type of dentifrice tube, is worth applying widely.

Four, description of drawings

Fig. 1 is the utility model external structure scheme drawing;

Fig. 2 is the utility model inner structure scheme drawing.

Five, the specific embodiment

As shown in Figure 1 and Figure 2, the utility model comprises the cylindrical hard tube body 1 that has loam cake 2 and manage the end 5.Loam cake 2 is exporting on 12 by screw collar.The pipe end 5, be provided with several knock holees 10, these knock hole 10 equidistant being arranged on the pipe concentrically ringed circumference at the end 5.Be provided with circular piston 6 in the inner chamber of body 1, the cavity on piston 6 tops is the material chamber 7 that is used to store lotion.Piston 6 sides have with internal chamber wall on the bayonet socket 14 that fastens of guiding card article 13, like this, piston 6 will move up and down along guiding card article 13, idle running can not occur.The top packing seal 8 that prevents leakage under the lotion that also is provided with of piston 6; The bottom at the pipe end 5 is provided with cylindrical base 3, and the center of this base 3 is provided with vertical thread rod 4.This thread rod 4 penetrates axially from the pipe end 5 and is threaded through body 1 inner chamber and with piston 6 centers.Base 3 also is provided with and manages the knock hole 10 corresponding positioning convex 9 at the end 5, and this positioning convex 9 cooperatively interacts with knock hole 10, can realize quantitatively extruding of lotion, and can adjust the extrusion capacity of lotion by the spacing of adjusting knock hole 10.The side of base 3 also is provided with some tread plates 11.
