Description
Technical field
This utility model relate to a kind of under gnotobasis the container in order to stored article, it can store the article of for example medical treatment or surgical operating instrument and so on.This container can adopt the structure of bag shape or other packaging arrangements are arranged.
Background technology
The sterile chamber that is used to store medical treatment or surgical operating instrument adopts bag shaped structure usually, and this bag shaped structure is by two plastics, and low density polyethylene (LDPE) for example is combined face-to-face along peripheral heat-sealing and forms.Have access portal on a slice plastics therein, cover a penetrating thin film above the opening, this penetrating thin film round the opening involution on bag shape main body.Penetrating thin film mainly contains two kinds of functions in this structure: one, it covers on the opening, can sterilize to the content in the bag.Thin film uses the strip of paper used for sealing involution that can peel off on packed main body, thereby can peel off from bag easily, so that take out content from opening part.Moreover thin film has been made permeability, is in order to use sterilizing gas (chemical gas or steam) to come the content in the sealing bag is sterilized after bag is sealed.Aperture on the thin film can allow sterilizing gas pass through, but can stop that but antibacterial or similar substance pass through.Penetrating thin film (being called tear tape) on this bag adopts surgical operation paper or the spunbond polyene of Arathene to make usually, and there is sale in these products Du Pont company, and its sales trademark is Tyvek.
" breathing freely " of tear tape is a very important place of this type of sterile bag.In order to allow sterilising cycle short as far as possible, tear tape must be as far as possible little to the resistance of the mobile generation of sterilizing gas.Unfortunately, in order to make the sealing strip that can peel off with low density polyethylene (LDPE), paper or Arathene must be coated or be carried out other processed, and its these needed processed then can reduce the permeability of thin film significantly.Adopt the sterilising cycle of this tear tape longer than the required time usually.Therefore, preferably adopt uncoated tear tape.This problem was set forth in United States Patent (USP) 4367816 the present inventor.The settling mode that he provided is the tear tape that adopts a bilayer, above one deck be uncoated penetrating thin film, the second layer then is an interlayer between penetrating thin film and sealing bag.This interlayer is a thin slice (normally plastics), and this thin slice both can form the involution that can peel off on the material of sack, simultaneously also with uncoated film sealing.This disclosed in 4367816 above-mentioned patents interlayer has duck eye, perforation, and perhaps otch passes through sterilizing gas.The invention in this early stage has been carried out very big improvement to prior art, but adopts its described structure to be easy to produce a problem, especially when making big sealing bag.When sterilizing gas outwards flowed, interlayer will be pushed down porous membrane, in some cases, can cause the area of the thin film that gas passes through to dwindle like this, passed through thereby hinder gas.Adopt manufacturing techniques available, can't in interlayer, cut big opening.If the opening of interlayer is done very greatly, for example,, will produce the difficult problem that some are made if the width of opening has surpassed 25% of interlayer width, this will further discuss hereinafter.Adopt the described manufacture method of description of the present utility model just can address these problems, use this method can also make a sealing bag, the ventilative area of this bag is all the same substantially with inside gas for outside mobile gas.The term that uses in description " length " and " width " then are to refer to respectively in manufacture process, the moving direction of the thin film on Bag Making Machine, and with the vertical direction of this bag machine direction.Use this invention, " width " of the sealing bag of making is may (in fact being possibly) longer than its " length ".
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of novel aseptic packaging that is used for stored article is provided.
An aseptic packaging that is used for stored article of the present invention comprises
A sealed container has and has the softish plastic wall of one side at least, and the opening of a predetermined length and width is arranged on the soft plastics wall of described container; And
The tear tape that can peel off of sealing up on described opening comprises on the described tear tape:
One penetrating thin film,
One interlayer, between described penetrating thin film and sealed container, and in their both involutions, described interlayer has an opening onesize with opening, and the width of this described interlayer split shed is more than or equal to the width 25% of interlayer.
Above-mentioned penetrating thin film is made by uncoated surgical operation paper or by uncoated Arathene.
Above-mentioned container is made up of two rectangular soft plastics thin slices, and these two plastic sheets are sewn to together along their periphery.
Embody one of sack of the present invention preferably embodiment by shelving face-to-face and forming in anter and rear panel that their common periphery is sewed up.Two sheet materials preferably all adopt low density polyethylene (LDPE).In order more clearly to set forth, describing sack of the present invention with a concrete sealing bag can be more convenient, but must understand, only is in order to illustrating in the description of this size of doing, but not in order to limit scope of the present utility model.The described here sealing bag 20cm length that is used as for example, 24cm is wide.A wide 3cm, the elongate channel opening of long 17cm are arranged on the center apart from the 7cm (length direction) at sack one edge.Take out stored content like a cork with regard to having a bigger opening like this.Covering on the opening is the high density polyethylene (HDPE) thin slice (interlayer) of a coating, and general 7cm is wide, the same with sealing bag long.Covering on the interlayer is the penetrating thin film that a piece of paper or Arathene are made, and it is the same with the size of interlayer.Paper or Arathene because permeability is arranged, can allow sterilizing gas pass through, but can not allow antibacterial and similar substance pass through.The area of penetrating thin film is big more, and disinfection cycle is just short more, and therefore, large-area penetrating thin film is best.The two sides of interlayer is all carried out coating (preferably adopting the bimetallic extruding) with very thin material at each face, and this coating material has the adhesion characteristic that it needs respectively to bag material and penetrating thin film.Preferably interlayer and penetrating thin film are very tightly bonding, but can peel off from low density polyethylene (LDPE).The mixture of various vinyl acetate thermoplastic polymers (EVA) and low density polyethylene (LDPE) can reach this order, and that this is the personnel of ordinary skill in present technique field is known.An opening is arranged on the interlayer, and the opening of itself and preceding low density polyethylene (LDPE) thin slice matches, and therefore the ventilation area of penetrating thin film is not just covered by interlayer, also just can not hinder flowing of sterilizing gas.Because some reasons that will go through hereinafter, above-described sealing bag can not successfully be made with existing technical matters.
Sealing bag is normally made on machine, and on this machine, the material of each layer of forming sealing bag is respectively to supply from the continuous net width of cloth mode of material webs separately.When the net width of cloth passed through machine, needed opening was cut, and the net width of cloth also is sealed to a sealing bag mutually, and last, the finished product sack is cut from the network width of cloth.Make the described sack of this description, need four net width of cloth, two low density polyethylene (LDPE) net width of cloth are two-layer as the front and back of sealing bag, and a narrow relatively high density polyethylene (HDPE) net width of cloth also has a same wide porous membrane net width of cloth with interlayer as interlayer.If there is not method of the present invention, in manufacture process, two the low density polyethylene (LDPE) net width of cloth and the penetrating thin-film network width of cloth can not produce any problem, but the interlayer net width of cloth then can cause the difficulty in the great manufacturing.Its reason has a big relatively clipping region with regard to being the interlayer among the present invention.If one of cutting surpasses the otch of plastic wire fabric width degree 25%, the tension force that exists in the net width of cloth will make the limit of the net width of cloth to anterior arch so, thereby produces fold on the net width of cloth.In manufacture method of the present invention, before the cutting opening, the interlayer of an additional relative narrower of involution on anter so just can be avoided this problem earlier.By the support of anter, the narrow interlayer net width of cloth forms trend folding or a fold and just can be avoided.Make two to throw the net after the width of cloth is fixed together tightly with strip of paper used for sealing, just can on anter and interlayer, cut an opening simultaneously.The otch of anter is last just as access portal.After otch was by cutting, penetrating thin film, interlayer and anter just were stitched together tightly by strip of paper used for sealing, the anter rear panel were stitched together with similar method at last again and had just finished the manufacturing of this invention container.
By the following detailed description and accompanying drawing, can a more complete understanding be arranged to this invention.
