Background technology

At present, the bottle cap water outlet internal orifice cover material that water dispenser uses with the drum water bottle capable on the market all is with the low density polyethylene (LDPE) the same with bottle cap body.Seal Design mainly contains plug-in (referring to patent US005232125), jacket-type (referring to patent US005392939) and Contiuum type three major types.Its function is to seal water outlet internal orifice (mark 16) to avoid water to flow out from bottleneck when drum stands upside down the insertion water dispenser.The design of Contiuum type is divided into " Q " font top-opening type (referring to patent CN301299736S) again, " ten " font top-opening type (referring to patent CN3050914), " " font top-opening type (referring to patent US00557304).Their interior flap all fuses with bottle cap.So be called the Contiuum type design.And the requirement of the water outlet internal orifice cover mold tool design accuracy of Contiuum type is very high, and the bottle cap plastic material requires quality good.Because " Q " font, " ten " font, "

" groove that splits of font requires thin and evenly.And the depth of these grooves that split break into small pieces after can being caused inner cap or difficulty to back down or back down when answering back to sudden force by the clever post of water inlet (mark 14) are fallen in the water; Water does not leak along the groove that splits before not backing down.In addition, be that the design of plug-in or jacket-type inner cap all might be by the clever post of water inlet (mark 14) when backing down with sudden force, plug or overcoat are all fallen into the water because of the nuance of the clever post design of different water dispensers or size can not 100% accurately be enclosed within on the clever post in it.The inner cap that feasible quilt pushes away is immersed in and causes secondary pollution in the potable water.Flap leaked in the bottle cap water outlet, misfit mutually the contact position at bottle cap inwall and bottleneck top also was to cause the immediate cause of leaking.Mostly insert the bottle cap inwall on the market and solve this seepy question with movable polyethylene pad.But pad is not produced because of the little general bottle cap originating firm of consumption, mostly needs outsourcing.And pad need be placed in the bottle cap.And pad can be brought foreign matter and bacterium into unavoidably in the process of producing, transport, store in a warehouse and be placed into bottle cap and the bottle cap inwall is caused secondary pollution.Although some bottle placer has the bottle cap sterilizing equipment decontaminating apparatus, all can't carry out disinfection to the tow sides of pad and foreign substance cleaning.Therefore, the sealing of bottle cap and health all are difficult to be guaranteed.

Summary of the invention

For the foreign matter and the problem of bacteria that solve the sealing of flap in the bottle cap water outlet and the placement of come off leaking of being caused and secondary pollution problem and bottle cap polyethylene pad may bring.The utility model provides a kind of foil sealing health bottle cap, and this bottle cap can thoroughly solve the water outlet inner cap and leak, comes off, and stops the secondary pollution problem that the leakproof pad brings.

The technical scheme that its technical matters that solves the utility model adopts is: flap food stage aluminium foil (mark 1) in the water outlet of bottle cap, the top of bottle cap water outlet internal orifice is by smooth region and have the unsmooth regional two parts of fine particle and forms (mark 11 and mark 12), it is poor with bottle cap water outlet internal orifice top formation fusion firmness that aluminium foil is covered under the electromagnetic induction effect, when the clever post of water inlet (mark 14) is answered back to the aluminium foil lid with sudden force, the zone that degrees of fusion is strong has sticked the aluminium foil lid, thereby swims in the water after avoiding the aluminium foil lid to be backed down.In addition, at the fixing food stage foaming packing ring (mark 2) of bottle cap inwall, and add uniform 16 bottleneck reed chocks (mark 8) at interval at the bottle cap madial wall, just can avoid that bottle cap leaks, bacterium and foreign matter placing the secondary pollution that the bottle cap inwall is caused when preventing drain gasket.

The utility model with the total technical characterictic of existing nearest technology is: water outlet internal orifice sealing mode and the anti-drain gasket of bottle cap inwall placement by the design bottle cap stop leaking of bottle cap to reach the purpose that the sealing bottleneck prevents bacterium secondary pollution bottled water.

The utility model is with the maximum different characteristic of existing nearest technology: flap replaces other material with aluminium foil in the water outlet of bottle cap, with unifor or 4,4 '-the polyethylene pad of the retaining washer replacement activity that the OBSH foaming generates.Change the design of the anti-drain gasket of bottle cap water outlet internal orifice sealing means and bottle cap fully.The utility model product materials is few, and is simple in structure, and directly, production technology is pollution-free, and On-line Product is once finished.Stop fundamentally on the market that flap leaks in the existing drum bottled water bottle cap water outlet, damaged and the bacterium of anti-drain gasket and the secondary pollution that foreign matter causes bottled water.

The specific embodiment

Among Fig. 1, aluminium foil covers the realization of thorough seal bottle cap water outlet internal orifice

In the bottle cap production process, add one procedure: locate to be inserted in bottle cap water outlet internal orifice with the aluminium foil of cardboard with the inner cap die sleeve at bottle cap water outlet internal orifice (mark 16).After bottle cap moved by load-transfer device and passes through the electromagnetic induction aluminium foil sealing machine, contactless aluminium foil is merged of aluminium foil sealing machine reached complete sealing effectiveness (mark 1) (see figure 1) on bottle cap water outlet internal orifice.And the band cardboard aluminium foil by electromagnetic induction after its cardboard separate automatically with aluminium foil along with removing of inner cap die sleeve.

Whether the technical matters that may exist is here: backed down by the clever post of water inlet (mark 14) easily by flap in the bottle cap water outlet after the foil sealing fully, and whether the lid of the aluminium foil after backing down can fall into (see figure 6) in the water.

Solution is: in two zoness of different of bottle cap water outlet internal orifice top surface design.The region surface of a small size is handled smooth (mark 11), and the remaining areas surface design becomes to have fine particle face (mark 12) (see figure 4).The unusual smooth area on the surface, merge at aluminium foil lid and the top of bottle cap internal orifice will be very firmly and even (mark 13) (see figure 3), and the degree that merges at its aluminium foil lid of the region surface that has the fine particle face and the top of bottle cap internal orifice is because the existence of fine particle and firmness reduces.Because the aluminium foil lid merges area with the top unit of bottle cap internal orifice and reduced because of the existence that particle is arranged,, aluminium foil lid unit area formed the degrees of fusion difference in two different zones thereby merging fastness.Withstand the (see figure 5) in an instant of aluminium foil lid when the clever post of water inlet (mark 14), the aluminium foil lid that has the fine particle region surface breaks away from bottle cap water outlet internal orifice top in advance, and the lid of the aluminium foil on the surperficial very smooth small size zone has been retained on the smooth small size zone when bottle cap inserts clever post fast because the unit firmness is strong.Thereby avoided the aluminium foil lid to descend slowly and lightly in water.(see figure 6)

Among Fig. 1, the foaming packing ring is fixed on the realization of bottle cap inwall

Before the production process of aluminium foil lid seal bottle cap internal orifice, add one procedure earlier, be ejected into uniformly in the bottle cap inwall circle groove by jet pipe with nonpoisonous and tasteless food stage foaming agent liquid.Foaming agent in the bottle cap inwall circle groove is foamed to produce nontoxic, tasteless, white, shinny foaming packing ring and accurately to be fixed in the bottle cap inwall circle groove rapidly.Seal bottle cap water outlet collar extension (mark 15) (see figure 2) by the hot pressing automatic labeling machine more at last.Whole production process is just finished on manufacturing line automatically since then.Avoided the secondary pollution between aluminium foil lid and the hot pressing trade mark label.

The selection of foaming agent: alternative foaming agent is various in style, and physical aspect is also different separately.The criterion that is used for passing judgment on is also a lot.Not all physics and chemical foaming agent all are suitable for the foaming packing ring of potable water bottle cap.Since to safety, health, low-carbon (LC), environmental protection, the energy, cost, temperature, etc. all multifactor influences to the plastic bottle closure aspect all need conscientious, comprehensively, take all factors into consideration.The utility model is designed most important several principles is: but under the condition of controlled speed and estimating temperature, the gas that selected foaming agent discharges is not only measured greatly, and duplicability is good; Gas and solid that reaction produces are nontoxic person, and for the poly-mer of foaming any harmful effect can not be arranged, and for example, produce color or bad smell.At last, be the cost problem, this also is a considerable criterion.The low-temp foaming agent is selected from numerous available chemical foaming agent, and mainly the problem that should consider is, the dissociation temperature of foaming agent should adapt with the processing of plastic temperature.There are two kinds of organic chemistry foaming agents to be accepted extensively by the low-temperature low-density polyethylene.

First kind is unifor (TSH).

Molecular formula C ₇H ₁₀N ₂O ₂S.It is the white crystals fine-powder.Relative molecular mass 186.Relative density 1.40～1.42.100～110 ℃ of fusing points.Be soluble in alkali, be dissolved in methyl alcohol, ethanol, MEK, be slightly soluble in water, aldehydes, be insoluble to benzene and toluene.100～110 ℃ of dissociation temperature are emitted nitrogen and low amounts of water, and gas forming amount is 110～125ml/g.Hydrolysis produces sulfonic acid in hot water, and emits nitrogen.Normal temperature is no moisture absorption deliquescence phenomenon down, and chemical property is stable.The gas that takes place and residue decomposition is nontoxic, odorless, do not pollute.The foam structure that this product produces is fine and closely woven, and evenly the goods shrinkage percentage is little, and peel strength is big, is particularly suitable for making closed-cell foam and gelatin sponge.

Second kind be 4,4 '-OBSH, or claim OBSH.

Molecular formula C ₁₂H ₁₄N ₄O ₅S.It is character white or light yellow crystalline powder.Relative molecular mass 358.39.Relative density 1.52.140～160 ℃ of dissociation temperature are emitted nitrogen and aqueous vapor, and gas forming amount is about 120ml/g.Be dissolved in cyclohexanone, ethylene glycol, ether, be slightly soluble in ethanol and warm water, be insoluble to benzene and gasoline.This product is the extremely wide foaming agent of comformability, and the title of omnipotent foaming agent is arranged.Can be used for PVC, PE, PP, ABS resin etc.Though contain ehter bond in its structure, highly stable.Dissociation temperature in resin is 120～140 ℃.Use sodium bicarbonate can make its activation, reduce dissociation temperature.The foam structure fine and even, decomposition gas and resistates are nontoxic, odorless, do not pollute goods.

These two kinds of foaming agents decompose the nitrogen that is produced environment are not polluted.And all be low form.Can save the energy resource consumption in the production.Therefore, the foaming agent of the utility model bottle cap is selected unifor TSH or 4,4 '-OBSH OBSH for use.

On the bottle cap production process because the installation procedure that has removed injection moulding, the installation procedure of water outlet inner cap and removed foamed gaskets makes that two procedures and former bottle cap production that the utility model bottle cap is increased are cooresponding on operation.But just differing widely aspect material saving, environmental protection, safety and the health.It is superior a lot of that the utility model bottle cap technology is wanted.
