Filter bag structure improvement

Abstract

This invention relates to an innovative design for a beverage filtration device, specifically an "improved filter bag structure." The main feature is a fixed structure at one end of a bag material with permeability and filtration properties, and a support block at the other end of the bag. The fixed structure controls the density of the bag material, and a special fitting mechanism allows the support block to be positioned at the bag end, easily attaching its support portion to the cup. Furthermore, the support block and bag are not limited by any material bonding, and the filtration density can be adjusted as needed to enhance the filter bag's practical functionality.

Claims

1. An improved filter bag structure, which mainly consists of two support blocks fixedly installed at the two outer ends of a bag body, with fold lines and slit lines respectively provided at the ends of the support blocks. The support blocks are separated by the slit lines of the support blocks, and the fitting blocks are movably connected to the support blocks by a connecting block. The main feature is that a practical filter bag structure for beverages is easily completed.

2. The improved filter bag structure as described in claim 1, wherein the bag body is made of a fiber material with appropriate density, water permeability and filtration characteristics of filter pores, and several fixing blocks are set at appropriate positions of the filter pores of the bag body, and connecting blocks are respectively set at both ends of the fixing blocks. By distributing the fixing blocks of specific shapes and quantities at the ends of the bag body as required, a special pattern can be presented on the surface of the bag body, and the fixing effect of the connecting blocks and the bonding blocks can be improved. It can also simplify the sealing and sealing operations of the bag body. Furthermore, other bags with different filter pore densities can be stacked and fixed with the connecting blocks to easily achieve the required filtration density. It does not require complex and high-cost molds and equipment, and also has the functions of being sturdy, durable and beautiful.

3. The improved filter bag structure as described in claim 1, wherein the support blocks provided at the two outer ends of the bag body are separated from the connecting block and the support block by means of a tangent line, and are bent by means of a fold line to bend the fitting block, the connecting block and the support block, so that the fitting block cooperates with the opening and closing action of the bag body, and the support block and the connecting block can be moved and separated by the mutual connection of the connecting block and the support block, so as to achieve the purpose of complete frame structure without wasting materials.

4. The improved filter bag structure as described in claim 1, wherein the adhesive block of the support block, after being separated by the slit line, has a larger and more stable area that adheres to the bag body, thus ensuring that the support block is securely fixed to the end of the bag body and is not easily detached. Furthermore, in conjunction with the connecting block and the connecting adhesive block, after the support block is pulled out, the space formed by the two end support blocks can span across the end of the cup body, allowing the bag body to be opened into a stable opening, which is convenient for holding food or pouring in boiling water. Because the whole structure is firmly fixed and has a high degree of adjustment tolerance, it can be easily placed on the end of cups of various sizes, which is convenient for users.
