Description

Technical Field

[0001] This utility model relates to the field of plastic container technology, and in particular to an environmentally friendly and biodegradable universal plastic container for food and cosmetics. Background Technology

[0002] In the food and cosmetics packaging industry, plastic containers are widely used due to their lightweight and good sealing properties. Environmentally friendly and biodegradable plastic containers, with their environmentally friendly advantages, have become an important direction for industry development. Currently, while some environmentally friendly and biodegradable food and cosmetic plastic containers on the market possess biodegradable characteristics, they have significant structural design flaws. On the one hand, most containers use a one-piece structure, requiring the entire container to be replaced when the contents need to be changed or the inner liner is damaged. This not only increases usage costs but also wastes resources due to frequent container disposal, contradicting environmental protection principles. On the other hand, some containers with inner liners have complex fixing structures between the inner liner and the bottle body, making disassembly and replacement inconvenient. Furthermore, the sealing effect between the inner liner and the bottle body is poor, easily leading to leakage problems. This is especially problematic for liquid foods or cosmetics, where leakage not only causes spoilage and waste but may also contaminate surrounding items. Utility Model Content

[0003] The purpose of this utility model is to solve the problems mentioned in the background art and to propose an environmentally friendly and biodegradable universal plastic container for food and cosmetics.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an environmentally friendly and biodegradable general-purpose plastic container for food and cosmetics, comprising a bottle body, an inner liner disposed inside the bottle body, and a bottle cap threadedly connected to the top opening of the bottle body. The inner liner is fixed inside the bottle body via a support plate fixedly connected to the inner wall of the bottle body by two sets of fixing components on the inner side of the bottom opening of the bottle body. A slot is provided on the inner wall of the bottle body near the bottom. The fixing components include a fixing block fixedly connected to the bottom of the support plate. An insert rod is slidably connected inside the fixing block. The insert rod is inserted into the slot. A pull rod is fixedly connected to one end of the insert rod away from the slot. A pull plate is fixedly connected to the other end of the pull rod. A spring is sleeved on the pull rod.

[0005] Preferably, a sealing ring is fitted around the top edge of the inner liner, and the sealing ring abuts against the top surface inside the bottle body.

[0006] Preferably, the top surface of the support plate has a circular groove, the inside of the circular groove is provided with a top plate, the bottom of the circular groove has a threaded hole, the inside of the threaded hole is threaded with a screw, the top end of the screw is fixedly connected to the top plate, and the bottom end of the screw is fixedly connected to a knob.

[0007] Preferably, the bottle body, bottle cap, and inner liner are made of the same material, and are all made of environmentally friendly and biodegradable polylactic acid material.

[0008] Preferably, limiting rods are symmetrically fixedly connected to both sides of the middle of the outer wall of the inner liner, and limiting grooves are opened on the inner wall of the bottle body corresponding to the positions of the two limiting rods, with the limiting rods being engaged inside the limiting grooves.

[0009] Preferably, a positioning block is fixedly connected to the outer wall of the support plate, and the positioning block is slidably inserted into the inside of the limiting groove.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the inner liner is securely fixed and easily disassembled inside the bottle body through the cooperation of the support plate and the fixing components. The support plate is connected to the inner wall of the bottle body through two sets of fixing components. The insert rod slidably connected in the fixing block of the fixing components is pushed by the spring and inserted into the slot of the inner wall of the bottle body, thereby fixing the support plate inside the bottle body, and thus fixing the inner liner placed on the support plate. When it is necessary to remove the inner liner, pull the pull plate. The pull plate drives the pull rod and the insert rod to move, so that the insert rod disengages from the slot, and the support plate and the inner liner can be taken out from the bottom opening of the bottle body. This avoids the problem of the need to replace the whole container as in traditional integrated containers. When the inner liner is damaged or the contents are changed, only the inner liner needs to be removed and replaced. The bottle body can be reused, which greatly reduces the cost of use, reduces resource waste, and conforms to the concept of environmental protection. Secondly, the operation of the fixing components is simple and convenient, without the need for complicated tools. Whether installing or removing the inner liner, it can be completed quickly.

[0011] 2. In this utility model, the cooperation of the knob, screw, top plate, and sealing ring effectively enhances the sealing performance between the inner liner and the bottle body. When the knob is turned, the screw rotates in the threaded hole and drives the top plate to move up and down. The upward movement of the top plate pushes the inner liner upward, so that the sealing ring at the top edge of the inner liner is tightly abutted against the inner top surface of the bottle body. This solves the problem of poor sealing and easy leakage between the inner liner and the bottle body in traditional containers. The top plate pushes the inner liner to make the sealing ring fit tightly, which greatly improves the sealing effect and can effectively prevent leakage of liquid food or cosmetics, ensure the quality of the contents, and avoid the waste of contents and contamination of surrounding items caused by leakage.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figure 1 - Figure 6As shown, this utility model provides a technical solution: an environmentally friendly and biodegradable general-purpose plastic container for food and cosmetics, including a bottle body 1, an inner liner 3 disposed inside the bottle body 1, and a bottle cap 2 threadedly connected to the top opening of the bottle body 1. The inner liner 3 is fixed inside the bottle body 1 by a support plate 4 fixedly connected to the inner wall of the bottle body 1 through two sets of fixing components 5 via the inner side of the bottom opening of the bottle body 1. A slot 7 is provided on the inner wall of the bottle body 1 near the bottom. The fixing component 5 includes a fixing block 501 fixedly connected to the bottom of the support plate 4. An insert rod 502 is slidably connected inside the fixing block 501. The insert rod 502 is inserted into the slot 7, and the insert rod 502 is away from the slot. One end of the bottle 7 is fixedly connected to a pull rod 504, and the other end of the pull rod 504 is fixedly connected to a pull plate 505. A spring 503 is fitted on the pull rod 504. A sealing ring 14 is fitted on the top edge of the inner liner 3. The sealing ring 14 abuts against the top surface inside the bottle body 1. A circular groove 8 is opened on the top surface of the support plate 4. A top plate 11 is set inside the circular groove 8. A threaded hole 9 is opened at the bottom of the circular groove 8. A screw 10 is threaded inside the threaded hole 9. The top end of the screw 10 is fixedly connected to the top plate 11. A knob 12 is fixedly connected to the bottom end of the screw 10. The bottle body 1, the bottle cap 2, and the inner liner 3 are made of the same material and are all made of environmentally friendly and biodegradable polylactic acid material.

[0017] The beneficial effects achieved in this embodiment 1 are as follows: through the cooperation of the support plate 4 and the fixing component 5, the inner liner 3 is stably fixed and easily disassembled inside the bottle body 1. The support plate 4 is connected to the inner wall of the bottle body 1 through two sets of fixing components 5. The insert rod 502 slidably connected in the fixing block 501 of the fixing component 5 is inserted into the slot 7 of the inner wall of the bottle body 1 under the push of the spring 503, thereby fixing the support plate 4 inside the bottle body 1, and thus fixing the inner liner 3 placed on the support plate 4. When it is necessary to disassemble the inner liner 3, the pull plate 5 is pulled. 05. Pull plate 505 moves pull rod 504 and insert rod 502, causing insert rod 502 to disengage from slot 7. This allows support plate 4, along with inner liner 3, to be removed from the bottom opening of bottle body 1. This avoids the need for complete replacement of traditional integrated containers. When inner liner 3 is damaged or its contents need to be changed, only inner liner 3 needs to be disassembled and replaced. Bottle body 1 can be reused, significantly reducing usage costs and resource waste, aligning with environmental protection principles. Furthermore, the operation of fixing component 5 is simple and convenient, requiring no complex tools for both installing and removing inner liner 3. All processes can be completed quickly; by setting a sealing ring 14 at the top edge of the inner liner 3, the sealing performance between the top of the inner liner 3 and the top surface of the back of the bottle body 1 can be improved; through the cooperation of the knob 12, screw 10, top plate 11 and sealing ring 14, the sealing performance between the inner liner 3 and the bottle body 1 is effectively enhanced. When the knob 12 is turned, the screw 10 rotates in the threaded hole 9 and drives the top plate 11 to move up and down. The upward movement of the top plate 11 can push the inner liner 3 upward, so that the sealing ring 14 at the top edge of the inner liner 3 is tightly abutted against the inner top surface of the bottle body 1, solving the transmission problem. To address the issue of leaks caused by poor sealing between the inner liner 3 and the bottle body 1, the top plate 11 pushes the inner liner 3 to ensure a tight seal with the sealing ring 14, significantly improving the sealing effect. This effectively prevents leakage of liquid food or cosmetics, ensuring the quality of the contents and avoiding spoilage and waste, as well as contamination of surrounding items due to leakage. Furthermore, the bottle body 1, cap 2, and inner liner 3 are all made of polylactic acid, ensuring consistent degradation performance across all components. After disposal, they can be simultaneously decomposed into carbon dioxide and water by microorganisms, leaving no residual pollution and meeting environmental protection requirements.

[0018] Example 2: Figure 3 - Figure 6 As shown, the inner liner 3 has symmetrically fixedly connected limit rods 6 on both sides of the middle of the outer wall. The inner wall of the bottle body 1 has limit grooves 13 corresponding to the positions of the two limit rods 6. The limit rods 6 are locked inside the limit grooves 13. The outer wall of the support plate 4 is fixedly connected to a positioning block 15, which is slidably inserted into the limit groove 13.

[0019] The beneficial effects achieved in this embodiment 2 are as follows: by the cooperation of the limiting rod 6 on the outer wall of the inner liner 3 and the limiting groove 13 on the inner wall of the bottle body 1, the position of the liner can be restricted to prevent the inner liner 3 from rotating or moving inside the bottle body 1, thus ensuring the sealing effect. It can also provide guidance for the inner liner 3 during installation, thereby improving installation efficiency. By the cooperation of the positioning block 15 on the outer wall of the support plate 4 and the limiting groove 13, the installation position of the support plate 4 can be accurately positioned, ensuring that the insertion rod 502 in the fixing component 5 is quickly aligned with the slot 7.

[0020] The working principle of this embodiment is as follows: First, confirm that the bottle body 1, inner liner 3, bottle cap 2, and other components are intact. Place the sealing ring 14 on the top edge of the inner liner 3. Then, align the limiting rod 6 on the outer wall of the inner liner 3 with the limiting groove 13 on the inner wall of the bottle body 1. Insert the inner liner 3 into the bottle body 1 along the limiting groove 13. Next, align the positioning block 15 on the outer wall of the support plate 4 with the limiting groove 13 on the inner wall of the bottle body 1 and push the pull plates 505 in the two fixing components 5 closer together. Push the support plate 4 into the bottom opening of the bottle body 1 along the limiting groove 13 until the insertion rod 502 of the fixing component 5 corresponds to the slot 7 on the inner wall of the bottle body 1. At this point, the insertion rod 502 automatically inserts into the slot 7 under the elastic force of the spring 503, completing the fixing of the support plate 4 inside the bottle body 1. Then, rotate the knob 12 at the bottom of the support plate 4. The knob 12 drives the screw 10 to rotate in the threaded hole 9. The screw 10 pushes the top plate 11 upward, and the top plate 11 pushes the inner liner 3 upward. The sealing ring 14 at the top of the inner liner 3 is tightly abutted against the inner top surface of the bottle body 1. Stop turning the knob 12 to complete the installation of the inner liner 3. Finally, connect the bottle cap 2 to the top opening of the bottle body 1 with threads to complete the assembly of the entire container. When the inner liner 3 is damaged or the contents are used up and need to be replaced, first unscrew the bottle cap 2, then turn the knob 12 in the opposite direction. The screw 10 drives the top plate 11 to move downward. Then pull the two pull plates 505 at the bottom of the support plate 4. The pull plates 505 drive the pull rod 504 and the insertion rod 502 to move. The insertion rod 502 compresses the spring 503 and disengages from the slot 7. At this time, the support plate 4 and the inner liner 3 are taken out from the bottom opening of the bottle body 1 along the limiting groove 13. Remove the old inner liner 3 and replace it with a new inner liner 3 with a sealing ring 14. Following the above steps for installing the inner liner 3 and fixing the support plate 4, reinstall the support plate 4 and the new inner liner 3 into the bottle body 1 to complete the replacement of the inner liner 3 and realize the reuse of the bottle body 1.
