Lining reinforced-type internal pocket

Abstract

The invention relates to a lining reinforced-type internal pocket, which comprises an outer layer unit and an inner layer unit, wherein the outer layer unit is provided with a pocket body, the upper end and the lower end of the pocket body are respectively provided with a funnel-shaped feeding port and a funnel-shaped discharging port, the inside of the pocket body is hollow and provided with an accommodating part, the inner layer unit is provided with a lining and a plurality of reinforced belts which are arranged between every two inner walls of the lining, the lining is sleeved inside the accommodating part of the pocket body and combined with the pocket body, the outer circumferential surface of the pocket body can be prevented from being deformed through the reinforced belts, so that the internal space volume of the internal pocket can be enlarged, and an effect for saving the transport cost can be realized.

Description

technical field [0001] The invention relates to an inner bag used on a space bag, in particular to a liner-reinforced inner bag which can increase the volume space of the inner bag and has the effect of saving freight costs. Background technique [0002] see figure 1 As shown, there is an inner bag 10 made of aluminum foil in the past. A rectangular bag body 11 is formed in the middle of the inner bag 10. A funnel-shaped inlet 12 and a material outlet are respectively provided at the upper and lower ends of the bag body 11. The mouth 13 and the inside of the bag body 11 are hollow to form a container 14. The material can be poured into the container 14 through the feed port 12, and then the inner bag 10 is vacuumed to achieve the effect of preservation. [0003] Although the above-mentioned inner bag 10 can achieve the use effect of containing raw materials, there are still some shortcomings in use. Generally, the aluminum foil inner bag 10 is mainly used in occasions that ...

AI Technical Summary

Problems solved by technology

[0003] Although the above-mentioned inner bag 10 can achieve the use effect of containing raw materials, there are still some shortcomings in use. Generally, the aluminum foil inner bag 10 is mainly used in occasions that need to be dry and moisture-proof, because the aluminum foil material is easily broken after being bent. Moisture-proof function, so the aluminum foil inner bag 10 should not have too many times of processing, this limit aluminum foil inner bag 10 can not make too complicated shape, see figure 2 As shown, when the aluminum foil inner bag 10 is generally filled with raw materials, the outer peripheral surface of the inner bag 10 will expand and protrude because the raw materials will expand the inner wall of the inner bag 10 outward. Multiple inner bags 10 are stacked on top of each other, and the expansion surfaces of each inner bag 10 are in contact with each other, leaving a lot of space at the corners to cause waste. Therefore, the internal volume of the inner bag 10 is generally small, the carrying capacity is limited, and the freight cost will be relatively increased.
