Description

The novel toothpaste pipe

Affiliated technical field

The utility model relates to a kind of novel toothpaste pipe, particularly relates to a kind of any toothpaste extrusion device that do not rely on, just a kind of novel plastic dentifrice tube that can make things convenient for, neatly toothpaste be extruded.Can be used for the ointment product of hose packings such as toothpaste, ointment, viscose glue, cosmetics, belong to the daily necessities technical field.

Background technology

Toothpaste is indispensable daily necessities during we live.Now a lot of toothpaste all are that we can feel during use with the plastic hose encapsulation, and when toothpaste had been used one section, it was not so easy extruding it.Because the flowing power of toothpaste is pinched it with hand, it not necessarily flows out from the mouth of pipe, usually can go in the pipe and go in other space, and toothpaste is hustled and bustled all to squeeze and do not go out.But if, may extrude again and cause waste too much with more energetically.Have only and used almost, the afterbody of the pipe that does not have toothpaste is rolled, do not allow toothpaste flow backwards, could extrude toothpaste from the mouth of pipe when toothpaste.But one looses one's grip, and rolled-up part can restore to the original state again.All to do so at every turn, obviously pretty troublesome.But if not like this, just can not successfully extrude toothpaste, can not squeeze toothpaste in the pipe very totally.So, many people are arranged when toothpaste does not also run out, just simply it has been thrown away, cause very big waste.These are weak points of existing plastics dentifrice tube.

This thing happens, is because the dentifrice tube of today is made with plastics mostly.After the plastics moulding at normal temperatures, it has the characteristic that will keep original shape.It is cylindric that dentifrice tube is made back typing, fills bottom sealing behind the toothpaste, seals to be yi word pattern.Toothpaste is used after one section, the space of toothpaste just appears not having in the place that toothpaste is squeezed away, to recover under its cylindrical elastic effect at plastic pipe, will produce vacuum in above-mentioned space, make you when squeezing toothpaste out of a tube, toothpaste is not to go out from the mouth of pipe, but is back to the space that does not have toothpaste, so toothpaste is hustled and bustled all to squeeze and do not go out, squeeze unclean.In a word, present plastics dentifrice tube uses cumbersome, and it is handy to be not so good as former metal dentifrice tube.

Early stage dentifrice tube is with metal or its alloy material manufacturings such as lead, tin, aluminium, because these metallo-ductility and plasticity, dentifrice tube is extruded and can recover that it is cylindric after the distortion, after using one section, can not allow toothpaste flow backwards from the bottom there not being toothpaste partly to roll, can satisfy operating needs.But because lead, tin, aluminium price height not only, and all be very easily with the metal of acid, alkali, salt attack, be easy to content with its packaging (as toothpaste, medicine, viscose glue, makeup etc., the chemical analysis that mostly contains complicated acid, alkali, salt character) plays the adverse chemical reaction, reduce it and use effect or toxigenicity.Plastics do not react with acid, alkali, salt, and cheap, thus not reusable lead, tin, the aluminum metallic material manufacturing of many afterwards dentifrice tubes, and replace with plastics.From safe and sanitary and economic angle, plastic hose is the perfect package material of ointment products such as toothpaste, medicine, viscose glue, makeup, but from angle easy to use, it is again not as metallic material.

For addressing the above problem, the inventor has designed many patented products, but all because of complex structure, the cost height, or use inconvenience and fail generally to promote.As the patent No. is 200420112617 invention " tooth-paste extruder ", " be made up of two clamping plate that combine, narrow meeting arranged between two clamping plate, and the dentation pressure roller on two clamping plate is relative; Circular-arc projection is arranged on one of them clamping plate ... ", it is constructed more than the dentifrice tube complexity.And for example application (patent) number: 200420094901, cry the invention of " intelligent toothpaste box ", dentifrice tube is arranged in the tooth case, the tooth-paste extruder that the toothpaste extrusion device that the tooth case is made up of push jack, push rod, spring, shell, handle is again made constitutes.Its structure is also quite complicated, and uses also inconvenient.

Summary of the invention

In order to overcome the inconvenience of extruding of existing plastics dentifrice tube existence, squeeze untotally, the deficiency of waste is arranged, the utility model provides a kind of novel plastic dentifrice tube, this dentifrice tube needn't use the toothpaste extrusion device of any complexity, also needn't increase manufacturing facilities, and only slight improvement be done in the inside of dentifrice tube, in the time of just can realizing squeezing toothpaste out of a tube, toothpaste can not flow backwards, extrude conveniently, squeeze totally, not waste.Make cheap plastics dentifrice tube give full play to its advantage, really can replace expensive metal dentifrice tube.

The technical scheme that its technical matters that solves the utility model adopts is: at the inwall of plastics Flexible tube for toothpaste, go out the concavo-convex body of some tubular grooves and cylindrical convex ridge along the tube axial direction pressure injection, the tubular groove places the demifacet of dentifrice tube cylinder inner wall, cylindrical convex ridge places another demifacet of cylinder inner wall, and the tubular groove is relative one by one with cylindrical convex ridge.Tubular groove mouth is made and is slightly less than cylindrical convex ridge diameter.When squeezing toothpaste out of a tube, under pressure, because the elasticity of plastics, top cylindrical convex ridge can embed in the following tubular groove.Convex ridge can be held in the following tubular groove after embedding and being slightly less than the groove mouth of its diameter, make dentifrice tube up and down two demifacets tightly stick together, do not have the space.

When using toothpaste, toothpaste seals from pipe bottom yi word pattern, bit by bit up squeezed, the place that toothpaste is squeezed away, in the tubular groove below cylindrical convex ridge embeds, make dentifrice tube up and down two demifacets tightly stick together, do not have the space.When squeezing toothpaste out of a tube, though the toothpaste of pressurized flow has certain pressure, be not enough to dentifrice tube tightly two demifacets up and down of phase embedding wash open, toothpaste does not have the route of retreat, just can only spill out from upper end outlet.Can bit by bit squeeze away toothpaste thus, and the situation that toothpaste flows backwards can not take place.The place that toothpaste is squeezed away, dentifrice tube two demifacets up and down just tightly stick together, and stop toothpaste to flow backwards, and reaching the metal dentifrice tube can roll the afterbody of the pipe that does not have toothpaste, the same effect that does not allow toothpaste flow backwards.After toothpaste used up, whole dentifrice tube two demifacets up and down was close together, and resembles a plastic sheet, does not have toothpaste therebetween residual.Realized squeezing toothpaste out of a tube and one pointed out a bit, do not flow backwards, squeezed totally thoroughly, the purpose of not wasting.

The beneficial effects of the utility model have 3 points: 1, the cheap and good-quality advantage of the existing plastics dentifrice tube of novel toothpaste pipe safe and sanitary has the convenient handy characteristics of metal dentifrice tube again; 2, make toothpaste squeeze totally, residual few, cut the waste; 3, make cheap plastics dentifrice tube can replace expensive metal dentifrice tube finally, save national resources and reduce consumer spending.

The specific embodiment

As can be seen from Figure 1, profile of the present utility model is identical substantially with existing dentifrice tube, is cylindric φ 2, and there is an outlet φ 1 upper end, and a word shape is sealed in the toothpaste posterior end of packing into.But different is, the I-I cutaway view of dentifrice tube is seen from Fig. 4, the inwall of dentifrice tube upper half plane 1, have some equidistant, the cylindrical convex ridge 3 of axial array.And the following inwall of demifacet, then have some equidistant, the tubular groove 4 of axial distribution, groove 4 is relative one by one with top convex ridge 3.

Fig. 2 is the outside of dentifrice tube upper half plane 1, is level and smooth; Fig. 3 is the appearance of demifacet 2 under the dentifrice tube, and the little raised line with the tube axial direction arrangement in parallel is arranged.As can be seen from Figure 4, these little raised lines are outer shape of demifacet inwall tubular groove 4 under the dentifrice tube.

Not easily separated in order to allow cylindrical convex ridge 3 embed in the following tubular groove 4, tubular groove mouth is designed to be slightly less than cylindrical convex ridge diameter.Utilize the elasticity of plastics, firmly just can be pressed into cylindrical convex ridge 3 in the following tubular groove 4 a little.In like manner, also must exert oneself a little, could from following tubular groove 4, separate cylindrical convex ridge 3.The power that this power produces in the time of must flowing greater than toothpaste guarantees the power that the toothpaste that is extruded produces when flowing with this, can not separate two demifacets about the dentifrice tube, and toothpaste can not flow backwards.After should making cylindrical convex ridge 3 be pressed into following tubular groove 4 during design, dentifrice tube two demifacets up and down is close to and is not had the space, could squeeze toothpaste totally thoroughly as far as possible.

When squeezing toothpaste out of a tube, seal from dentifrice tube bottom yi word pattern and to begin to squeeze, under the finger pressure effect, two demifacets are squeezed up and down, toothpaste is squeezed away, cylindrical convex ridge 3 above the dentifrice tube just is embedded in the following tubular groove 4, because the elasticity of plastics, after cylindrical convex ridge 3 embeds and is slightly less than the tubular groove mouth of its diameter, closely be embedded in the following tubular groove 4, two demifacets are close together about making dentifrice tube, do not interspace, and toothpaste is thoroughly squeezed away.Toothpaste can flow under finger pressure, and the toothpaste that flows has certain pressure, but the insufficient pressure that toothpaste flows forces toothpaste to spill out from the upper end outlet so that two demifacets up and down of tightly phase embedding are washed open.After whole toothpaste used up, dentifrice tube up and down two demifacets was close together, and resembles a plastic sheet, does not have toothpaste therebetween residual, had realized squeezing toothpaste out of a tube one pointing out a bit, did not flow backwards, and is totally thoroughly crowded, the purpose of not wasting.

Based on the foregoing description, the orientation of cylindrical convex ridge 3 and tubular groove 4 can axially parallel with dentifrice tube, vertical or become certain angle of cut, as long as groove is relative one by one with convex ridge, when the cylinder dentifrice tube was crushed, groove and convex ridge were just identical just.

Based on the foregoing description, the cross section shape of groove and convex ridge can be circular, also can be ellipse, rhombus or triangle.It is just not easily separated to allow convex ridge be embedded in the following groove.

Based on the foregoing description, concavo-convex body can be the groove convex ridge of strip, also can be the concavo-convex body of point-like, resemble hidden discount one by one, the shape of concavo-convex body can be cylindrical body, globoid, prismatic body, and the concave volume convex body is relative one by one, becomes point-like to be distributed in the cylinder dentifrice tube respectively up and down in the two demifacet inwalls.As long as convex body can embed in the concave volume, and can closely interlock just.
