Abstract

An ink filling container comprises an ink filling nozzle and an ink holding part, wherein the ink filling nozzle is provided with a narrow nozzle part, a wide part and an ink channel connecting the two parts. The ink holding part is a soft bag, and the ink holding part is provided with an opening sealed and connected with the outer wall of the wide part. As the ink holding part is arranged into one soft bag, ink can be filled by self weight without external force. Ink filling process is stable, and ink filling effect is good.

Description

The refilling container

Technical field

The utility model relates to a kind of liquid container, especially a kind of refilling container that adds ink injection in ink-jet printer cartridge.

Background technology

Ink-jet printer uses print cartridge to provide ink to print work, and after the ink in the print cartridge used up, print cartridge mostly went out of use, thereby caused the pollution of environment and the waste of resource.Along with the enhancing of people's environmental consciousness, injecting ink in using up the empty cartridge of ink after, a lot of people reuse.

For inject ink in print cartridge, multiple refilling container has appearred, as needle tube type injection ink device and various ink-filling bottle.Figure 1 shows that a kind of common ink-filling bottle, have spring bottle and elongated ink-filling needle.When adopting this kind ink-filling bottle to carry out refilling, make the ink filling port of ink-filling needle insertion print cartridge, the extrusion bottle of exerting oneself, bottle is compressed distortion, thereby ink is clamp-oned in the print cartridge.Because bottle has specific shape, need apply external force when adding ink injection in print cartridge, and externally applied forces can't guarantee uniformity, adds the not steady of black process thereby cause, and easily produces bubble.Because these refilling containers have specific shape, structure is comparatively complicated in addition, thereby it is bigger to take up room, and production cost is higher.

Summary of the invention

The purpose of this utility model is to provide a kind of and adds China ink steadily, and refilling container simple in structure, that production cost is low.

For this reason, the utility model provides following technical solution:

The refilling container comprises: add black mouth, the one end is thin mouth portion, and the other end is the broad major part, has one and runs through thin mouth portion and the most ink channel of broad; Ink holding portion, ink holding portion are a soft bag, and have an opening that is tightly connected with the most outer wall of broad.

Be set to soft bag by the ink holding portion, make ink need not the external force effect and can carry out refilling by self gravitation.Existing ink tank must rely on the external force extruding that ink is injected in the print cartridge when refilling.During ink tank refilling of the present utility model, external atmospheric pressure acts on to ink by soft bag, and under atmospheric pressure and the effect of ink self gravitation, ink can overcome the air pressure in the print cartridge and flow into reposefully in the print cartridge, need not additionally to exert pressure again.

Simultaneously, it is few to adopt soft bag to consume material, occupies little space, and saves the convenient simultaneously transportation of cost.

More concrete scheme is most outer wall of broad and the welding of soft bag opening that adds black mouth.Compare with other connected mode, adopt the welding manner good sealing effect, technology is also simpler.

Scheme is that the most of cross section of broad that adds black mouth is arranged to lenticular more specifically.So setting can make add black mouth roomy to be easier to welding and sealing with soft bag.

Another more concrete scheme is that the diameter that adds the ink channel of black mouth diminishes gradually from the most of extremely thin mouth portion of broad.So setting can make ink be difficult for adding the generation obstruction of black mouth place.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing thereof the utility model is elaborated.

As shown in Figure 2, the refilling container by sealing cap 1, add black mouth 2 and soft bag 3 is formed.Sealing cap 1 adopts the good sizing material of elasticity to make, and adding black mouth 2 can make with plastic material, the strong PE material of soft bag 3 general available plasticity.Compare with other refilling container, refilling structure of container of the present utility model is simple, materials are few, production cost is low.

To shown in Figure 5, add roomy 23 and middle connecting portion 22 that black mouth 2 comprises that front end is more flat than thin mouth 21, the tail end of taper as Fig. 3, connecting portion 22 is provided with anti-skidding rib, adds in the black mouth 2 to have ink channel 24.Compare with thin mouth 21, the size that adds the connecting portion 22 of black mouth 2 and roomy 23 is bigger, thereby the diameter of its inner ink channel 24 also can be set to the diameter greater than thin mouth place ink channel 24, the cross section that is ink channel 24 can be set to become big gradually from front end to tail end, add tattooing needle and compare with the elongated Mo Guanhuo that adds, ink flowing in ink channel 24 is more unobstructed, is difficult for blockage phenomenon.

As shown in Figure 6, soft bag 3 can by a monoblock PE material folding back welding except that folded edge other limit and form, thereby the mid portion on the limit relative with folded edge does not weld together and is set to peristome 31, forms ink accommodation section 32 in welding edge 33 and the folded edge.To add roomy 23 opening of putting into peristome 31 of black mouth 2 then, and it will be tightly connected, thereby add black mouth 2 by the ink fluid connection in ink channel 24 and the ink accommodation section 32 with welding manner.

As shown in Figure 7, when adding China ink with the refilling container, take off sealing cap 1 earlier, thin mouth 21 is inserted in the ink filling port 41 of print cartridge 4, then the refilling container is stood upside down, the ink that holds in the ink accommodation section 32 is flowed in the print cartridge 4 through the ink channel 24 that adds in the black mouth 2 under atmospheric pressure and self gravitation effect, with apply external force add the China ink traditional approach compare, the refilling process is more steady, thereby is difficult for producing bubble in print cartridge, and refilling is effective.After refilling is finished, take off the refilling container, cover sealing cap 1 from the ink filling port 41 of print cartridge 4.

More than be preferred embodiment of the present utility model, the utility model includes but not limited to this, and the technical scheme of modes such as all employing equivalent transformations all drops in the protection domain of the present utility model.
