Description

The container that liquid is used

Technical field

The present invention relates to the container that liquid is used, in more detail, relate to be contained in self-priming mechanically, hold the container of viscosity higher liquid.

Background technology

The chest that sack is equipped with in inside shown in Fig. 7 is an example of liquid container in the past.The chest that sack is equipped with in inside has with the wrapper of band ripple or outer container 36 that ground paper is made and is contained in the endogenous pyrogen 35 of the usefulness thin film fabrication in the outer container 36.Liquid or fluid containment are in endogenous pyrogen 35.Endogenous pyrogen 35 has the injection discharge orifice 5 of injection and discharge current body and function.The chest of sack is equipped with in inside, is divided into the chest that has the injection discharge orifice 5 that protrudes from outer container 36 and in use just injecting the chest that discharge orifice 5 pulls out from outer container 36.The chest of sack is equipped with in this inside, generally is the container that holds the lower liquid of viscosity ratio such as soy sauce, wine, imaging liquid.

When liquid container is used for holding the higher fluid of viscosity ratio, for example, hold the printing ink that tartar sauce, stencil or screen printing are used, perhaps during mayonnaise, only rely on gravity to be difficult to fluid is taken out.Therefore, be by means of attracting fluids from injecting discharge orifice 5, could be equipped with fluid internally in the chest of sack and take out.

During fluid in attracting the inner chest that sack is housed, discharge injecting the chest that near the discharge orifice 5 fluid can be equipped with sack soon internally., endogenous pyrogen 35 but can be owing to distortion shown in long and short dash line and dotted line a, b, c, d takes place in attraction.Be in the following time of state shown in the dotted line d at endogenous pyrogen 35, inject near discharge orifice 5 parts and stopped up by endogenous pyrogen 35.So the position just remains in endogenous pyrogen 35 away from the fluid that injects discharge orifice 5 places.Therefore, just can not discharge fluid expeditiously.

Therefore, once proposed to be attached on the inside face of outer container 36, prevented to block the scheme of injecting discharge orifice 5 by means of a part that makes endogenous pyrogen 35., make in this way, the contraction of endogenous pyrogen 35 is just inhomogeneous, and its effect is not ideal.

In recent years, requiring for bulk article can be discarded with its packing material easily., if plastic container, the container after discarded the use can produce following point.Because plastic container are all bigger, the expense height of transportation and keeping.If plastic container are embedded in underground, it can not resolve into germ again, can be left behind.If plastic container are burnt,, damage stove easily because the heat that burning is produced is a lot.

Summary of the invention

The specific embodiment

The feature of novel concepts of the present invention particularly in claims of the application, can be well understood to.Described below the reference accompanying drawing has been read, current be desirable embodiment after, will clearer understanding be arranged to objects and advantages of the present invention.

Below, the container 100 according to the first embodiment of the present invention is described.

Fig. 1 represents to inject the container 100 under the state of fluid.Container 100 after Fig. 2 A and Fig. 2 B represent to fold.Container 100 has front 1, the left side 2, the back side 3, the right side 4, top 6 and following 7.Four sides the 1,2,3, the 4th, usefulness, for example, the first cascade film 110 that aramid layer/ethylene vinyl alcohol copolymer compound layer/polyethylene layer is constituted is formed.1 near on the angle of bottom in front, has formed the hole of injection and discharge current body and function.Inject discharge orifice 5 and insert in these holes, welding is in front on 1.

The first film 110 is that perhaps co-extruded shaping processing method is made with various stacked job operations such as dried layered manner, wet lamination method, extruding layered manners.The formation of desirable the first film 110 is: aramid layer/sex change polyethylene layer/polyethylene layer; Ethylene-vinyl acetate co-polymer alkali compound layer/sex change polyethylene layer/polyethylene layer; Aramid layer/ethylene-vinyl acetate co-polymer alkali compound layer/sex change polyethylene layer/polyethylene layer; Biaxial stretch-formed polyethylene terephthalic acid salt deposit/aramid layer/sex change polyethylene layer/polyethylene layer; Biaxial stretch-formed polyethylene terephthalic acid salt deposit/ethylene-vinyl acetate co-polymer alkali compound layer/sex change polyethylene layer/polyethylene layer; Biaxial stretch-formed polyethylene terephthalic acid salt deposit/aramid layer/ethylene-vinyl acetate co-polymer alkali compound layer/sex change polyethylene layer; Biaxial stretch-formed polyethylene terephthalic acid salt deposit/aramid layer/sex change polyethylene layer/polyethylene layer.Desirable sex change polyethylene preferably uses anhydrous maleic acid sex change polyethylene.

Injecting discharge orifice 5 preferably makes with poly injection moulding.Under the desired strength condition with higher, inject discharge orifice 5 and also can make with the multi-cavity injection molding method, have sandwich structure.Injecting on the discharge orifice 5, be used for supporting the flange 5a (referring to Fig. 3) of container 100 when being preferably disposed on injection and discharging fluid.That flange 5a can do is circular, the various shapes arbitrarily of hexagon, pentagon, quadrangle or the like.In addition, inject discharge orifice 5 and can also have the neck 5b that is arranged on the flange 5a back side.The wall thickness that injects discharge orifice 5 is generally 0.6～3.0mm, it is desirable to 0.8～2.0mm.

Above 6 and following 7, for example, be to form with the second layer laminate film 120 that biaxial stretch-formed polyethylene terephthalic acid salt deposit/aramid layer/ethylene-vinyl acetate co-polymer alkali compound sex change polyethylene layer/polyethylene layer constitutes.Second film 120 also has oil resistance and water resistance.On a face of second film 120, use can not welding material, and on its another face, then use can welding material.

Second film 120 can use: biaxial stretch-formed polyethylene terephthalic acid salt deposit/aramid layer/sex change polyethylene layer/polyethylene layer; Biaxial stretch-formed polyethylene terephthalic acid salt deposit/ethylene-vinyl acetate co-polymer alkali compound layer/sex change polyethylene layer/polyethylene layer; Biaxial stretch-formed polyethylene terephthalic acid salt deposit/aramid layer/ethylene-vinyl acetate co-polymer alkali compound layer/sex change polyethylene layer; Biaxial stretch-formed polyethylene terephthalic acid salt deposit/aramid layer/sex change polyethylene layer/polyethylene layer; Or the like the laminate film that constituted.

Second film 120 preferably has the rigidity lower than the first film 110.Because the second softer film 120 is when injecting the discharge fluid, than the first film 110 distortion to the inside earlier, so container 100 is just folded up than being easier to.In order to regulate the rigidity of second film 120, can be the reduced thickness of second film 120.In addition, also can do the rigidity of second film thinnerly than higher barrier layer (ethylene-vinyl acetate co-polymer alkali compound layer, aramid layer or biaxial stretch-formed polyethylene terephthalic acid salt deposit).

Below, the manufacturing process of container 100 is described.

As shown in Figure 3, two second film 120 doublings, make layer that it can not welding relative to each other.These two second films 120 are inserted between two the first films 110.At this moment, the folding line of two second films 120 is arranged to relative to each other.Then, shown in Fig. 2 A and Fig. 2 B, with the peripheral part of the heated sealant method welding the first film 110 and second film 120.Detailed says, middle weld the 8, the 9th is formed by two the first films 110 of welding.Other weld (edge weld part) 10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25 then forms by the welding the first film 110 and second film 120.As shown in Figure 3, when welding, the first film 110 and second film 120 overlap.Since in each second film 120 after folding can not welding layer relative to each other, so be not welded together.On edge weld part 10～25, the first film 110 relative to each other and second film 120 just are welded together.By means of this welding, just be divided into the accommodating chamber of regulation, thereby can have obtained the container of folding up 100 on plane.The container 100 on plane is expanded, just can obtain square shapes of containers 100 (Fig. 1).

Inject discharge orifice 5 preferably welding in advance on the first film 110.The fusion temp of the film among first embodiment is 220 ℃.For

weld

8,9 in the middle of forming, preferably make the length of minor face (left side of Fig. 2 A, 2B and the right) of the first film 110 longer than the length of the minor face of second film 120.In other words, the distance that preferably folding line of two second films 120 is separated regulation.At this moment, when Foldable container 100, between the folding line of two second films 120, form the gap.Therefore, owing to can prevent from container 100, to be separated into two accommodating chambers temporarily,, can not remain in the container so liquid can both be poured out from container 100.

Fig. 4 represents the container 200 of the second embodiment of the present invention.Fig. 5 A and 5B represent the container 200 folded up.

Weld

8,9 in the middle of container 200 has two, edge weld part 14～25, and the

weld

26,27,28,29,30,31,32,33 of 45 degree that approximately tilt.Container 200 just is easy to expand into regular cube by means of inclination weld 26～33.Because these inclination welds 26～33,8 triangle auricle 26a, 27a, 28a, 29a, 30a, 31a, 32a, the 33a after each bight of container 200 has formed the first film 110 and second film 120 and is piled up just.One side each weld 26～33 sealing cooresponding auricle 26a～33a.Therefore, just can prevent that fluid from flowing in the triangular cavity that forms between the first film 110 and second film 120,, can prevent that fluid from flowing into the inside of each auricle 26a～33a that is.

When will using the fluid attractor (not shown) that has suction nozzle when container 100,200 is discharged high viscosity fluids.The O RunddichtringO that rubber is made is housed on suction nozzle.The determining positions plate of fluid attractor is connected on the neck 5b that injects discharge orifice 5, suction nozzle is inserted inject discharge orifice 5.By means of the O RunddichtringO suction nozzle and injection discharge orifice 5 are sealed.Like this, just can from container 100,200, suck out liquid.When on using wall, having the fluid attractor that attracts the hole, then allow and inject discharge orifice 5, it closely is attached on the above-mentioned wall round attracting the hole.

Fig. 6 A and Fig. 6 B represent the modification of container 100,200.Owing to be fixed on the determining positions plate of fluid attractor, perhaps be fixed in the such outer container of Fig. 7, so front 1 just is difficult to distortion injecting discharge orifice 5.Therefore, shown in Fig. 6 B, just second film 120 that rigidity is lower is the 6 and following 7 direction distortion to injection discharge orifice 5 promptly.In addition, 3 directions of distortion to front 1 along with top 6 and following 7 in the back side move.

When container 100,200 was folded up, the inner 5c (referring to Fig. 3) that injects discharge orifice 5 was just near the inside face of second film 120.For this reason, can protective film 34 (referring to Fig. 1) welding or be connected second film 120 with the corresponding part of inner 5c of injecting discharge orifice 5 on, that is, and welding or be connected below on.In this case, intensity and rigidity owing to following 7 have all improved, thereby can avoid container 100,200 damaged because of injecting discharge orifice 5.

By means of forming rib or groove 5d, just can avoid second film 120 to stop up injecting discharge orifice 5 at the inner 5c that injects discharge orifice 5.Therefore, just can all eject fluid, can not remain in the container 100,200.

Because the good rigidly of container 100,200 is so can paste poster paper on the outside face of container 100,200.

Container 100,200 is suitable for storing the higher liquid of viscosity ratio, for example: printing ink, chocolate cream, mayonnaise, catsup, liquid detergent, dress material hand modifier, paint, lining cement, honey or the like.In addition, container 100,200 is specially adapted to the device that forcibly fluid ejected from container.

Container 100,200 can be folded into the tabular of general planar except injecting discharge orifice 5.Therefore, when not injecting fluid, container the 100, the 200th, small-sized object.The keeping of container 100,200 and transportation are all very convenient, can reduce housing cost and cost of transportation.In addition, in the factory of injecting liquid, do not need to be provided with special-purpose container manufacturing equipment.

Because protective film 34 has been arranged, improved the rigidity of container 100,200, just can discharge fluid safely.Protective film 34 can use film of synthetic resin, perhaps ground paper.Protective film 34 can be installed on the inside face or outside face of second film 120.

Because bevelled weld 26～33 has been arranged, the shape of container 200 is very stable, can discharge fluid at an easy rate from container 200.In addition, by means of bevelled weld 26～33, when injecting fluid, container 200 can very successfully erect and be cube shaped.In addition, when discharging fluid, second film 120 is folded up earlier than the first film 110.After forming bevelled weld 26～33, also can cut away auricle 26a～33a.

Can also with the part of

weld

14,15,16,17 corresponding second films 120 on form hole.In addition, can also be doing smallerly with the width of

weld

14,15,16,17 corresponding second films 120.In this case, on the position of its pertusate position or narrow width, the first film 110 of the first film 110 in the place ahead with the rear is welding together.The dimensionally stable that like this, just can keep container 100,200.

Usually, in the time will from container 100,200, taking out fluid, container 100,200 be placed to allow it top 6 up, but the placement direction of container 100,200 also can change.For example, also can be placed to container 100,200 and allow side 2 up, perhaps container 100,200 be placed to allow it top 6 and side 2 the border up.
