Background of invention
Because of the packing problem on deformation that exists difference of pressure to cause between sealed package inside and ambient pressure is widely known by the people in packing business.For some packing, as some plastics or metal, this packing distortion may be restored.Thin-walled, part flexible packaging are normally made by this sensitive material, therefore are subject to the influence of the problems referred to above especially.
Some factors that may cause existing between above-mentioned packing inside and outside difference of pressure are arranged.For example, the content of this packing can be chemically unstable or can with the gas reaction that is present in this package top space, perhaps, react with packing itself in some cases.Any chemical reaction relevant with liquid contents may cause the generation of gas, makes the hypertonia of package interior, or causes the absorption to headspace gas, makes the hypotony of package interior.
When the temperature during container is by can and sealing obviously is different from transportation, conveying and the temperature between the storage life, also there is difference of pressure between pressure in this container and the ambient pressure.The another kind of possibility that difference of pressure produces is to be caused by the difference between the ambient pressure at the ambient pressure at container filling place and another diverse geographic location place.
Prior art has proposed the solution of several employing valve systems, and these schemes can avoid packing inside and outside difference of pressure.These schemes that proposed also relate to various vent caps, and this vent cap sheds the pressure that is produced in packing by emergent gas.For example, FR-A-2259026, US-4136796 and DE-A-2509258 have disclosed a kind of packing of self ventilating, and it comprises a Breathable films that covers on the hole that communicates with the external world.This film is by not seeing through liquid but ventilative material is made.Therefore, packing can comprise can to the outside discharge gas but have can the forfeiture its sealing property the hole.Another example is EP-A-593840, its year a kind ofly be used for the container that splendid attire can produce the liquid of pressure, this container is made by the thermoplastic material that comprises network of micropores.Described network of micropores is an aeration, can see through liquid but have.
The inventor finds, can make its part forfeiture permeability to air when flowing product contacts this film.In addition, viscous liquid goods or have the goods of certain affinity not flow back into the packing from this film to this film.Therefore, if described film touches described goods, the part substantial loss that covers by the described goods that do not flow away from this film of this film venting capability.The situation that this its venting capability of packing forfeiture can occur like this.
Before the customer bought, described goods just might spatter on described film because of the vibration of the packing of filling during transportation of packing and conveying.The contriver finds that the amount of splashing down during transportation and conveying is enough to thoroughly destroy the aeration of this packing.The contriver finds that also also there is similar defective in other blow and vent system such as valve.
Therefore, the purpose of this invention is to provide a kind of lid of packing or being used for this packing, wherein, can prevent that the goods of being adorned from contacting blow and vent system, thereby prolong the ventilatory effect of this packing or lid.
Summary of the invention
The invention provides a kind of lid (10) that is used to adorn the packing (10) of flowing product or is used for this packing.Described packing or the lid that is used for this packing comprise a breather (20), and when the pressure in this packing was different from the pressure of outer package, this breather made gas to pass through between the inside of packing and outside.This breather can see through gas, but can not see through flowing product.This packing or the lid that is used for this packing also comprise a fender guard (30), and it can prevent that described goods from spattering on breather, and therefore, this fender guard has guaranteed that gas can pass through described breather.

Detailed Description Of The Invention
Accompanying drawing referring to packing top and lid thereof.Screw on/go into or snap-on type lid, or turnover, push-and-pull or the sealing of rotation lid can be described lid with pack between coupling device.
To at first describe Fig. 1 a below, be described as a lid then as a packing.When Fig. 1 a represented a kind of cutaway view of packing, this packing (10) (its part only is shown) comprised a hollow body (11).This hollow body can contain any flowing product.It is desirable to, this hollow body to a certain degree is being soft, and it can be out of shape with the pressure of package interior and the difference of pressure of ambient pressure.For example, the present invention also comprises the bag of being made by thin plastics.In addition, the suitable shape of this packing comprises roughly cylindrical shape, cone barrel, ellipse, square, rectangle or flat ellipse.
This hollow body is applicable to the antiseep packing of flowing product.Hereinafter, flowing product also comprises paste, missible oil, gel, emulsion and slurry.For example, described goods can comprise household article, use or dishwashing detergent crust and house detergent, shampoo, bleaching agent, individual/cosmetics and skincare product, butterfat and toothpaste as laundry.According to the present invention, described hollow body can hold the flowing product that can produce pressure in packing.For example, described goods can be the liquid laundry goods, and it contains bleaching agent, particularly the peroxy type bleaching agent.It is desirable to, the viscosity of described goods is 200-5000cps, and 800-1800cps is better, and 1300-1600cps is best, and wherein, this viscosity is that the rotating speed with 360rpm records with the Brookfield viscosity agent under 20 ℃.
When Fig. 1 a represented the cutaway view of a lid, lid (10) comprised a roof (17) and a sidewall (18).This lid can engage with above-mentioned packing with leakage-preventing form.In another kind of preferred embodiment of the present invention, described packing or lid (10) can comprise an outlet (shown among Fig. 2 12).It is desirable to, described packing or lid are to be made with the fabricate block of stratiform, lamination or co-extruded form by plastics, metal, paper or these materials.These materials also can be reusable edibles.The preferred material of described hollow body comprises plastics, as polyethylene (high or low density), polyvinylchloride, polyester, polyethylene terephthalate (=PET), extrudable PET, polypropylene, polycarbonate and nylon.Described plastics can use or be combined into coextrusion thing, stratiform or laminate separately.
Another key character of described packing or lid (10) comprises a breather (20).The pressure and the atmosphere outside pressure of this breather energy balance package interior.Therefore, the hypertonia inside this breather can be avoided packing or low excessively.In fact, the gas that described breather allows to be disengaged by the dress goods is discharged to the outside by the inside of packing, and vice versa.When this packing was in stand up position, described breather was positioned at the top of packing above the dress goods.In fact, cause hypertonia or low excessively gas to accumulate in the top of packing usually.Therefore, help the outside or inner of gas flow packing.
Described breather comprises at least one hole.It is desirable to, this breather comprises at least one hole (21) and a film (22).This film can improve the not leakage property of this packing and don't can obviously reduce its venting capability.Described hole connects the inside and outside of this packing.Specifically, described hole (21) allow gas to flow to its outside by the inside of packing, and vice versa, so that the pressure in the packing keeps identical with outside atmospheric pressure or be lower than at least making Packaging Bottle that the obviously pressure of distortion take place.Hole size should be suitable for passing through of gas.It is desirable to, this hole is circular, and diameter is at least 0.5mm, is preferably 1～3mm.Those skilled in the art can be selected the quantity in hole, so that allow enough gas to pass through.
Described film (22) is positioned between the content (11) and hole (21) of described hollow body, covers described hole.It is desirable to, this film can not see through liquid, but can see through gas.Therefore, described film can provide a kind of barrier that can not see through liquid, allows gas to pass through simultaneously.It is desirable to, described film is to be made by any material that can be made into thin layer, and can be used for coverage hole (21).This film must see through gas stream, and can pass through gas under less difference of pressure.It is desirable to, when pressure reduction is low during to 100mbar, gas stream also can pass through this film, and gas stream also can will be better by this film during to 5mbar when pressure reduction is low.The thickness of film can be selected, but preferably in the 0.2mm-2mm scope.This film can comprise any material that can make thin layer basically, as has finely porous plastics, paper or metal.Preferably membraneous material comprises the cellular plastic film.Finely porous size on the described film should make gas pass through under low pressure reduction, simultaneously liquid non-permeate.It is desirable to, this micropore is 0.1～5mm, and 0.2-1mm is better.
The preferred microporous film that is used for this purpose has:
-nonwoven plastic film is that trade mark is sold with TYVEK by E.I.Du Pont Company particularly
The spunbond polyethylene film of nonwoven, TYVEK wherein, Style10 is by carbon
Fluoride was handled, to have high liquid impermeability;
-by Gelman Seience company (600, Seuth Wagner Road,
Ann Arbor, MI48106 US) with VERSAPOR is trade mark
The casting of selling on a kind of nonwoven support (nylon or PET) third
The olefin(e) acid copolymer has the hydrophobic after a fluorine monomer is handled, this product
Product are best.
Can handle the microporous membrane material of described film (22), reducing its surface energy, thereby improve the not leakage property of this membrane material.Reduce the surface energy of this membrane material, packing (10) goods of adorning when containing surfactant component for improving its not leakage property particular importance.It is desirable to, in this case, the specific surface energy of described membrane material should be lower than the specific surface energy of the goods that contain inhibiter, so that realize the complete impenetrability of product content thing basically.
An object lesson that can reduce the processing of surface energy is that fluorocarbon is handled, and this processing comprises micro-fluoro carbon materials is fixed on the membrane material surface.In fact, fluorination treatment can reduce the microporous membrane material of described film by the wetting possibility of flowing product inclusion.But, when handling the described microporous membrane material of film of the present invention, should not destroy the permeability to air of this film with this carbon fluoride.For example, a kind of carbon fluoride material that is used for carbon fluoride processing of the present invention is that trade mark is sold with SCOTCHBAN by 3M company.
Film (22) can be used for and places hollow body (11) inside, is positioned at by any way between inclusion and described hole (21), to keep it according to liquid of the present invention not permeability and aeration.Therefore, the mode of use can comprise uses adhesives or with the position of described film heat seal around in described hole, or uses the mechanical device such as anchor clamps or hot-die dash, or inserts described film during the molding of this packing.As indicated above, employed application apparatus should obviously not destroy the ventilation capacity of aeration film.Therefore, any adhesives that it is desirable to be adopted also is hole permeability to air or that can not clog this film.
This film also can be contained on the shell.Its size be particularly suitable for packing of the present invention or lid shell can (Via Roma 50,40069, Zola Predosa (BO) Italy) buy from GVS.In a kind of optimum implementation, the production of described shell and film (22) installation in this shell can be finished by one " operation of insert molding ", wherein:
-with device of a matrix input, this diaphragm is preferably by a film material
The material roller input;
-in described device, downcut at least one film from described diaphragm, and
Put it into a shell therein in the forming mould;
-then that shell is molded around described film substantially, so that film is fixed
In this shell." substantially around " in case be meant end here,
This step will produce a shell that has film, wherein, and this film
The two sides all can enter air, but this film is securely held in shell
In.
Can make shell on the support material or by this film is clipped between two or more plastic sheets by film (22) is bonding or heat seal.
As another key character of the present invention, described packing or lid comprise a fender guard (30).This fender guard can prevent that the goods of being adorned from spattering and be dissolved on the breather (20).In this article, splashing down a speech is meant when liquid substance vibrates discontinuous and of short duration contacting with a surface in packing.The phenomenon of splashing down of the flowing product of adorning mainly betides during transportation or the conveying, and it is dangerous higher that vibrate this moment.The contriver finds that when dress liquid touched described hole or film, this hole or film can be lost its permeability to air.In fact, the contriver finds that described flowing product or partially liq goods can not fully flow out from described hole or film, flow back in the packing.Like this, described hole or film may be covered by goods, that is: any position that covers described film by the goods that do not reflux all can reduce its venting capability.Therefore, the venting capability of this packing is lowered or forfeiture significantly.
For the viscous liquid goods or with the material around described film or the hole flowing product of certain affinity is arranged, situation is especially true.Its example has the liquid of the non-Newtonian flow characteristic of showing or has low-surface-energy (＜30 dyne/cm
2) liquid.For example, the liquid that contains inhibiter shows non-Newtonian flow characteristic usually.In this article, " non newtonian " goods are meant to have full-bodied goods under low shear rate, otherwise its viscosity is low under high-rate of shear.Therefore, the backflow of non newtonian goods is poor, because described backflow is feature with the low shearing speed, therefore, the viscosity of this goods is bigger.
Before the customer bought, particularly during packed and transported or conveying, when the packing of filling was vibrated, described flowing product may spatter and melt on described hole or film.The contriver finds, splashing down in transportation and during carrying is normally with the ventilation capacity of thorough this packing of destruction.The contriver finds that the ventilation capacity of other blow and vent system such as valve also may be compromised.
