Background

At present, the filling of the fluid is mainly to draw the fluid from the upper part of the packaging container by various types of fluid pumps, however, the above filling method has the following problems:

(1) and the fluid in the packaging container is more remained, which causes waste.

(2) And if the waste is dangerous, the treatment cost of the dangerous waste is increased.

(3) And the energy consumption of the fluid pump is high during operation.

(4) Some fluids can also generate VOCS gas, and when the equipment is installed, environmental protection departments require the installation of VOCS gas collecting and processing devices, so that the cost is high.

(5) When viscous fluid such as ink, grease, resin, glue and the like is extracted from the upper surface of the packaging container, a sucker is usually adopted, a fluid pump is installed on the sucker, downward pressure needs to be applied to a pressure plate in the using process, the viscous fluid inside the packaging container often overflows along the periphery of the pressure plate, and the pollution of the viscous fluid and the waste of materials are caused. In addition, the sucker is generally made of non-metal materials for sealing, fatigue damage or aging can occur in the using process, the sealing is not tight, and high replacement cost is caused when the sucker needs to be replaced. Meanwhile, the periphery of the sucker is sealed by non-metal materials, and certain extrusion force is required between the sucker and a packaging container, so that the packaging container is difficult to replace and long in time. Therefore, it is necessary to provide a further solution to the above problems.

Detailed Description

The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.

The utility model provides a fluid pail pack inner bag, its fluid that is suitable for to hold includes: printing ink, lubricating grease, lubricating oil, coating, paint, dye, resin and glue. The inner bag of the fluid packaging barrel comprises: bag body, protective layer, discharge gate, inner cup stay cord, flap.

The technical solution of the present invention is illustrated below with reference to an embodiment.

As shown in fig. 1 and 2, the inner bag of the fluid packaging barrel of the present embodiment is placed in the outer packaging barrel when in use, so that the fluid does not contact with the outer packaging barrel, excessive solid waste or dangerous waste caused by the contact of the fluid with the outer packaging barrel is avoided, and meanwhile, the fluid residue in the built-in inner packaging bag, such as ink, lubricating grease, lubricating oil, coating, paint, dye, resin, glue, etc., is very little. And the material is withdrawn from the bottom. When the outer packaging barrel is replaced, the operator can replace the outer packaging barrel cleanly without contacting materials.

The fluid packaging barrel inner bag of this embodiment includes: the bag comprises a bag body 1, a protective layer 2, a discharge hole 3, an inner cover 4, an inner cover pull rope 5 and a bag cover 6.

The bottom of the bag body 1 is provided with the discharge gate 3, and the sack has been seted up at the top, inner cup 4 set up in inside the

discharge gate

3, 5 one end of inner cup stay cord connect in on the inner cup 4. When in use, the inner cover 4 can be pulled out by the inner cover pull rope 5; the inner cap 4 can also be removed using a special tool, avoiding the body from coming into contact with the fluid. The working environment of the staff is improved.

The bag cover 6 is connected to the discharge port 3 through threads, seals the discharge port 3, seals the inner cover pull rope 5 between the bag cover 6 and the inner cover 4, and the protective layer 2 is compounded on the surface of the inner part of the bag body 1, and a distance is kept between the protective layer 2 and the bag opening. The protective layer 2 is an oxygen-isolating layer or an oxygen-isolating light-isolating layer, and has the function of preventing the internal fluid from being oxidized or deteriorated during vacuum packaging or long-term storage.

Further, the size of the opening is consistent with the size of the bottom of the inner bag of the fluid packaging barrel, or the size of the opening is larger than the size of the bottom of the inner bag of the fluid packaging barrel. In addition, the radial section of the bag body 1 is circular, oval, polygonal or special-shaped, and can be customized into other special shapes according to the requirements of packaged objects.

Meanwhile, the inner part of the inner bag of the fluid packaging barrel is in a vacuum-pumping state, or a nitrogen-filling state, or a sealing state. So, when having avoided traditional extraction material, to filling actions such as compressed air, air exhaust inside the container, it is short to change the pressure disk time, because the material is with the inner packing bag contact to carry out the sealed processing of evacuation, do not have the fluid adhesion, also need not to handle traditional fluid and remain, can practice thrift operating time, can also reduce the time of washing hands.

When the packaging container of this embodiment uses, in the fluid extraction in-process, the fluid of fluid pail pack inner bag the inside does not contact with the air, and extraction equipment is clean and tidy, to the fluid that has volatility VOCS, can the gaseous pollution to the environment of the VOCS that significantly reduces. In addition, when residual fluid, particularly viscous fluid, exists in the inner bag of the fluid packaging barrel, the residual fluid can be completely extruded by corresponding extruding equipment, and if the fluid is fluid with good fluidity, the fluid in the packaging container can be completely extracted.

To sum up, the utility model discloses set up the discharge gate in the bottom of the bag body is after filling fluid to fluid pail pack inner bag the inside, and the sack is sealed or vacuum seal. In the using process, the fluid flows out from the bottom of the bag body or is pumped out from the bottom of the bag body by a pump, and in the whole material-feeding process, the fluid in the bag body is not contacted with the air, so that the generation of volatile organic compounds (VOCS gas) is avoided.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
