Description

Container

But the present invention relates to the package of the material of a kind of disperse in liquid and the application of this package.Specifically, the present invention relates to the package as the material of forms such as concentrated chemical fertilizer, this chemical fertilizer forms dilute solution or suspending fluid by adding water.

Always exist control and restriction dangerous material and potential dangerous device and operator and the contacted requirement of environment.For example, many agricultural chemicals are made particle or powdery by prescription, they before using, be dissolved in earlier before promptly spraying or disperse in water.When with the garden tube of traditional upper shed, carton, bag packaging, for crop spraying operation person, spray and mix when irritating when pouring agricultural chemicals into crop by working hole, especially out of doors, often be in when blowing situation, exist the danger of pollution.Therefore just there is one to make the article of packing pour liquid into and not make environment and operator be subjected to the requirement of its package that influences.

The invention provides a kind of to adding the package of the article in the liquid dielectric to.Wherein, this package comprise one be easy to dissolve and/or disperse in liquid dielectric first and one be not easy to dissolve and/or disperse another part in liquid dielectric, this package can comprise the content that is generally granular or powdery.The representative type package is a container that is used for particle and powder.It has an openable end, and this end is dissolved in or disperse is closed and sealed in a paper of water.

This container can be the box or the bag of paper or cardboard system, and it can be with one deck plastic sheet as lining, as the polyethylene thin layer.Its end, can simply fold in the bottom and form, and dissolves in by one then or disperse is fixed in the paper of water, and this paper slip is fixed in promptly fixed position by adhesive agent.

This paper is preferably such: when being got wet by water and container is taken after support base, for the weight of content in the container, paper is wanted weak and was preferably in 7 seconds and forces the end to open in about 10 seconds to being enough to.

Like this, container can be put into a water pot by a working hole, bedews the bottom in second at 4-5, is suggested the surface of water then, and 2-3 is after second, and the bottom is by the weight force open of content, and this content is poured in the jar with not producing any dust.

For the facility of using, the top of container preferably is heat-sealed and is equipped with a handle.In order to prevent to get wet prematurely, as be exposed in the rainwater, this container preferably is contained in the moisture proof outer container, it is taken out from outer container during use again.In addition, as a kind of processing mode, outer container can also hold to use stays the interior water droplet of container afterwards.

Perhaps, but easily molten/disperse part of package can be by a kind of scalable by overplate protection insoluble or that can not the disperse material make.Like this, only before using, just overplate is peeled off, Yi Rong/disperse is partly come out.

But dissolve in or disperse in the paper of water, can be mainly to constitute or constitute by any other material by carboxymethyl cellulose, the made paper of these materials has enough dry tenacities, so that sealing has been full of the bottom of the container of content, and when being got wet by water, it is very weak that this material becomes soon.

This be dissolved in or disperse is depended on the weight of container dimensional and its content product in the thickness of the paper of water, for example, its suitable thickness range is from 30 microns to 200 microns, preferably from 60 to 200 microns.

The content of container can comprise one or multiple chemical fertilizer and/or agricultural chemicals, as powdery or granular pesticide and bactericidal agent.In addition, can comprise the parcel of one or more water-soluble not agricultural chemicals of the same race, so that provide a final solution or a suspending fluid that contains the estimated rate agricultural chemicals.This package also can be used for other materials, as dyestuff or pigment.

In a preferred embodiment, the invention provides a package (being generally a bag or box), it has some sidewalls and one by the formed bottom of one or more sidewall folded parts.These folded parts are not adhered to one another or adhere to sidewall, but are retained, but so that by being dissolved in or disperse provides a bottom in the sticking tablet that adheres to this part and/or sidewall of water.Like this, the dissolving of sticking tablet can make sack be transformed into the pipe at a no end, and content just can not have with hindering to be poured out.

Package can have enough rigidity or enough flexible, or there promptly have rigidity to have again to be flexible.Package can be the form of bag, bag, box, cup, tube or dish.They can lining or lining not.The dissolving of package/disperse part can comprise as be used for sealing bag or bag sutured portion, be used for sealing dixie cup or tube lid stick portion or form the part of package with paper or film, as a sidewall of box; The top of cup, tube or dish; Or the end of bag.But except carboxymethyl cellulose, also comprise polyvinyl alcohol (PVOH) and polyethylene oxide (PEO) for the suitable material of the film of solubilized one disperse.These other material all is the thermal plastic material and is heat-sealable.Using casting film and/or coated paper is easily.

The present invention also provides a kind of method of a kind of material in the liquid dielectric of adding, and it comprises: for the package of the above-mentioned type provides content; But and partly immerse medium to the solvable and/or disperse of major general's package; Like this, dissolve a part of this package and therefrom discharge content.

In order to be easier to understand the present invention.To describe some embodiment in conjunction with the accompanying drawings, wherein:

Fig. 1 is the transparent view of the bottom of package before the sealing;

Fig. 2 has represented the folding end of package shown in Figure 1;

Fig. 3 represented that a slice dissolves in or disperse in the position of the paper of water;

Fig. 4 has represented the plan view of a foldable bag of not opening.

With reference to accompanying drawing, Fig. 1-3 has represented a package 10 that has

wall

2,4,6,8, and its crease mark is indicated by long and short dash line.The end of

wall

2,4 is by folding along

joint

12,14,16,18,20,22, and the end of wall 6,8 is folded into given position shown in Figure 2 along joint 24,26.But place a slice water soluble or disperse in the paper 28 of water, as shown in Figure 3 at folded end then.

After package is filled with, as behind the herbicide of packing into,, can prepare then to use with top seal.In use, the end of package, be inserted into a water pot, and herbicide will become the solution suspending fluid and be used for spraying there, mention package then so that the wet end and water disengage.The weight of rapid lost strength of paper and content forces the end to be opened, and content is fallen into the water.

Bag 100 shown in Figure 4 is self-opening school bag shape bags, is depicted as and is folded into flat condition.In use, it can cannot not become foldingly and become a cube bag that has the top 112 of opening.The rectangular base 114 of bag 100 can be easily by flap 116,118, and 120 and 122 forms as envelope fold and form.Yet, to compare with convenient bag, flap 116,118,120 and 122 is not sealed mutually, but is placed on a rectangle flaky material 124 on the flap and above being enclosed in, thereby seals effectively at the end 114 of bag 110.Rectangle flaky material 124 is made in the paper of water by the water-soluble film or the film that covers.Material 124 is applied to the end 114 of bag 110 by using the water base adhesive mixture.

The filling and at top seal of some sacks like this according to usual operation.The bag that filling is good just can be placed on the dish after sealing, or is placed in the box, and stores and provide in usual mode.

In order to use bag 100, operator's (perhaps may a machine) catches bag 100 near end 112, this end is closed, and bottom 114 is dipped into liquid, aqueously then, and then proposes from liquid and a bag end 114 is suspended in several centimeters in liquid surface top.But water-soluble then/disperse is in material 124 dissolving or the disperses of water, and like this, the content in the bag is released into liquid.When the content of bag 110 when liquid, aqueous, especially be stirred that rod stirs or during continuous flow, content just scatters when liquid, aqueous.Empty then bag can suitably be disposed.
