Description

Technical Field

[0001] This utility model relates to a container bag with an inner lining. Background Technology

[0002] FIBCs (Flexible Intermediate Bulk Containers) are a type of unitized container, used with cranes or forklifts to achieve unitized transportation. They are suitable for transporting bulk granular materials and are widely used in the food, grain, pharmaceutical, chemical, and mining industries. The drawback of existing FIBC technology is that their single-layer structure results in poor sealing, particularly for food storage, making them prone to localized spoilage. Based on years of experience and market needs, our company has designed this invention. Utility Model Content

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0020] like Figure 1-2 As shown, this utility model relates to a container bag with an inner liner, including an outer bag and an inner bag 10 that can be contained within the outer bag, and also includes a bag opening spring clip 101 and a notch ring 41, the shape of which matches the inlet of the inner bag. Both the outer bag and the inner bag include an inlet and an outlet, wherein the height of the inlet of the inner bag is greater than the height of the inlet of the outer bag, and the diameter of the inlet of the inner bag gradually decreases from the port direction to the inward direction. A detachable filling funnel 4 is provided inside the inlet of the inner bag.

[0021] As a technical improvement, the inner bag's inlet is provided with a protruding rib 100. This rib is made of a high-strength, flexible plastic material. This material ensures the rib has sufficient hardness for fixing and supporting, while also allowing for deformation to adapt to different usage scenarios. The rib has a circular cross-section. The notched ring 41 is used to cooperate with the clamp to fix the inlets of the inner and outer bags. The notched ring is a flexible rubber ring. In use, the inlet of the inner bag is flipped outwards to simultaneously wrap around the inlet of the outer bag. Then, the notched ring is wrapped around the outside of the inner bag's inlet. The clamp is used to hold the inlets of the inner and outer bags, the notched ring, and the filling funnel. The notched ring acts as a skeleton, and the filling funnel acts as a guide.

[0022] like Figure 1 As shown, sealing ropes 6 are installed on the inlet on the top surface and the outlet on the bottom surface of the outer bag. An inner baffle structure is installed inside the inlet and outlet, arranged in a ring shape. The inner baffle structure consists of multiple baffles 8, which prevent material overflow during feeding and discharging. These baffles are arranged in a ring around the inside of the inlet and outlet. The structure can be trapezoidal or rectangular. A first buckle 91 and a first rope are installed on the inner baffle structure at the inlet. Adjusting the position of the first rope within the first buckle allows for the expansion and contraction of the inlet and the locking mechanism. A second buckle 92 and a second rope are installed on the inner baffle structure at the outlet. The buckles are of a common structure, operating on the principle of a belt buckle, enabling expansion and contraction and locking. For ease of transport, four lifting straps 5 are installed at the corners of the bag. The loop of each strap is 30cm high, and a portion of the strap is completely sewn to the bag, with a length greater than 50cm, to enhance stability.

[0023] As a technical improvement, a marking area 7 is provided on the surface of the bag, the marking area including a document pocket and a label.

[0024] As a technological improvement, the outer bag is a woven bag comprising a polypropylene (PP) layer 12 and a polyethylene (PE) layer 13.

[0025] As a technological improvement, the inner bag includes a polyester layer (PET) 14, an aluminum foil layer (AL) 15, a nylon layer (PA) 16, and an ethylene layer (PE) 17.

[0026] As a technical improvement, the inner bag is small at both ends and large in the middle. It has a diameter-changing area at the contact position with the inlet and outlet. The middle part is the bag body. The total height of the inlet and the diameter-changing area is 840mm, and the total height of the outlet and the lower diameter-changing area is 1060mm.

[0027] As a technical improvement, a rubber block 18 is provided at the corner of the inner bottom of the outer bag. This block serves as both a barrier and a reinforcement at the corner. It is a rubber block with a concave, curved surface. The block is made of highly elastic, wear-resistant rubber with good chemical corrosion resistance. This material adapts to the usage requirements of the container bag in different environments, ensuring its long-term effectiveness. The block is approximately triangular in shape, with right-angled sides of 80mm and 100mm, a hypotenuse of approximately 128mm, and a height of 20mm. This size design fully covers the corner area of ​​the inner bottom of the outer bag, providing effective isolation and reinforcement. The concave surface has a radius of curvature of 50mm. This curved design better conforms to the shape of the corner of the inner bottom of the outer bag, increasing the contact area between the block and the outer bag and improving stability. The block is firmly attached to the corner of the inner bottom of the outer bag using strong adhesive.

[0028] In practical use, the inner bag is placed inside the outer bag, and then a filling funnel is used to assist in filling.

[0029] The inner bag's inlet is located inside the outer bag's inlet, secured by the second buckle and the second rope, and finally sealed with a sealing rope.
