Abstract

The utility model provides an ink bag for an ink cartridge. The ink bag comprises a bag body used for containing printing ink, and a pressure reduction pipe, wherein the bag body is communicated with the pressure reduction pipe, and the bag body and the pressure reduction pipe are made in an all-in-one blow moulding manner; and the pressure reduction is provided with a U-shaped pressure reduction portion. As a result, the ink bag made in an all-in-one blow moulding manner is very simple in structure; during the production process, only one set of blow moulding moulds is needed, and thus compared with conventional structures, a large amount of mould cost is saved, and the production cost is substantially reduced; furthermore, the process flow only includes blow moulding and is very simple, the difficulty in production is small, the process control cost is reduced, and at the same time, the production is completed in one step, and thus the production cycle is shortened and the production efficiency is high; and the U-shaped pressure reduction portion enables the ink bag to have more precise control of ink supply amount, and the supply of ink is more stable.

Description

A kind of print cartridge ink sac

[technical field]

The utility model belongs to the ink-cases of printers technical field, relates in particular to a kind of print cartridge ink sac.

[background technology]

At present, what common ink-cases of printers used on the market is the ink sac structure that labyrinth structure proportioning valve film control print cartridge internal ink consumes, and perhaps uses by the synthetic ink sac of PET, aluminium foil and other materials and is welded on the ink sac structure that plastic injection-moulded nozzle forms; Structure is very complicated, and the amount of parts of formation is extremely many, and is die needed many, and the cost die cost is high, and technology controlling and process cost and manufacturing cost are higher, and production procedure is complicated, and the assembling difficulty is large, and the production cycle is relatively long, and efficient is slow.

[utility model content]

In order to solve the above-mentioned technical problem that exists in the prior art, it is a kind of simple in structure that the utility model provides, and is easy to produce, and the process-cycle is short, and efficient is higher, the print cartridge ink sac that cost of manufacture is low.

The technical scheme that the prior art problem that solves the utility model adopts is:

A kind of print cartridge ink sac includes utricule, relief pipe for Ink cartridge, and described relief pipe one end is connected, communicates with described utricule, and the integrally blow moulding.

Further, described relief pipe is provided with a U-shaped relief portion.

The beneficial effects of the utility model are as follows:

The utility model passes through technique scheme, integrally blow moulding ink sac originally, and structure is very simple, and production process only needs a cover blow mold, compare with traditional structure and to have saved a large amount of die costs, greatly reduced cost of manufacture, and technological process only is blowing, extremely simple, production difficulty is little, has reduced the technology controlling and process cost, produces simultaneously to settle at one go, shortened the production cycle, production efficiency is high; And U-shaped relief portion makes the amount control out of ink of this ink sac more accurate, out of ink more stable.

[description of drawings]

Fig. 1 is the structural representation of a kind of print cartridge ink sac embodiment described in the utility model.

[specific embodiment]

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

As shown in fig. 1:

The described a kind of print cartridge ink sac of the utility model implementation column, include utricule 1 and relief pipe 2, wherein, described utricule 1 is mainly used in Ink cartridge, described relief pipe 2 one ends are connected, communicate with utricule 1, and the integrally blow moulding, the other end is connected with this ink cartridge nozzle (not showing among the figure), and described relief pipe 2 is provided with a U-shaped relief portion 21.

Like this, this ink sac adopts blow molding process one-body molded, and structure is very simple, and production process only needs a cover blow mold, compare with traditional structure and to have saved a large amount of die costs, greatly reduced cost of manufacture, and technological process only is blowing, extremely simple, production difficulty is little, has reduced the technology controlling and process cost, produces simultaneously to settle at one go, shortened the production cycle, production efficiency is high; And U-shaped relief portion 21 makes the amount control out of ink of this ink sac more accurate, out of ink more stable.

Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
