Description

Tear-free food preservation antibacterial film cover Technical Field

[0001] This utility model relates to the field of food preservation device technology, and in particular to a tear-free food preservation antibacterial film cover. Background Technology

[0002] Plastic wrap covers are a convenient and practical food packaging material with good tensile strength, transparency, and water resistance. These plastic wrap covers can quickly and easily wrap food, thereby extending its shelf life.

[0003] When using existing plastic wrap covers, they are sometimes not only used to cover containers and protect the food inside, but also serve as temporary containers. If the food inside the container is no longer needed, it can be transferred into the plastic wrap cover by inverting the container, and then the container can be removed.

[0004] At this time, the membrane cover will serve as a temporary container. However, the membrane cover itself is prone to damage due to insufficient strength during use, which is a drawback.

[0005] Therefore, a tear-free food preservation and antibacterial film cover is provided to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a tear-free food preservation and antibacterial film cover.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An antibacterial liner is fixedly connected inside the plastic wrap;

[0010] Multiple sets of reinforcing ribs are fixedly connected to the antibacterial liner in a ring shape, with one end fixedly connected to an elastic gathering ring and the other end converging at the center of the plastic wrap. The reinforcing ribs are used to enhance the strength of the antibacterial film cover.

[0011] Preferably, a drainage strip is fixedly connected to the reinforcing rib, and the drainage strip is used to guide the condensate water to flow to the reinforcing rib.

[0012] Preferably, the drainage strip is located at the center of the reinforcing rib, and the two splices are arranged in a T-shape.

[0013] Preferably, the food preservation film is made of PE material.

[0014] Preferably, the antibacterial liner, reinforcing ribs, and drainage strips are all made of zinc oxide nanomaterials.

[0015] Preferably, the width of the reinforcing rib is 3-6 mm.

[0016] Preferably, the drainage strip has a thickness of 1-2 mm and a height of 0.5-1 mm.

[0017] Compared with the prior art, this utility model provides a tear-free food preservation and antibacterial film cover, which has the following beneficial effects:

[0018] This invention effectively improves the strength and quality of the membrane cover by adding reinforcing ribs, reducing damage. At the same time, the antibacterial liner reduces bacterial growth, facilitating long-term food preservation. The drainage strip can, to some extent, divert condensate, which not only helps improve strength but also reduces the impact of condensate droplets on the food. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example:

[0027] Referring to Figures 1-5, a tear-free food preservation antibacterial film cover includes a preservation film 1 with an elastic gathering ring 2. The film is characterized by further comprising: an antibacterial inner liner 3, fixedly connected inside the preservation film 1; and multiple sets of reinforcing ribs 4, fixedly connected in a ring shape to the antibacterial inner liner 3, with one end fixedly connected to the elastic gathering ring 2 and the other end converging at the center of the preservation film 1. The reinforcing ribs 4 are used to enhance the strength of the antibacterial film cover. A drainage strip 5 is fixedly connected to the reinforcing rib 4, guiding condensate water to flow to the reinforcing rib 4. The drainage strip 5 is located at the center of the reinforcing rib 4, and the two sections are joined in a T-shape. The preservation film 1 is made of PE material, and the antibacterial inner liner 3, reinforcing ribs 4, and drainage strips 5 are all made of zinc oxide nanomaterials. The width of the reinforcing rib 4 is 3-6 mm, the thickness of the drainage strip 5 is 1-2 mm, and the height is 0.5-1 mm.

[0028] The tear-free food preservation and antibacterial film cover in this device mainly consists of a preservation film 1, an elastic gathering ring 2, an antibacterial liner 3, reinforcing ribs 4, and a drainage strip 5. The functions and materials of each component are as follows:

[0029] Plastic wrap 1: Made of PE material, it has basic flexibility and sealing properties, and is suitable for different container shapes.

[0030] Elastic tightening ring 2: A ring-shaped elastic structure used to tighten the edge of the membrane cover, fit the container opening, and ensure a tight seal.

[0031] Antibacterial liner 3: Zinc oxide nanomaterials are used to cover the inside of the preservation film 1. The antibacterial properties of the nanomaterials destroy the bacterial structure, inhibit growth, and extend the food preservation period.

[0032] Reinforcing rib 4: Made of zinc oxide nanomaterial, 3-6mm wide, radially distributed, with one end connected to elastic constriction ring 2 and the other end converging at the center of the membrane cover, strengthening the overall strength of the membrane cover and preventing stretching and compression deformation.

[0033] Drainage strip 5: Made of zinc oxide nanomaterial, 1-2mm thick and 0.5-1mm high, it is connected to the reinforcing rib 4 in a "T" shape and located in the center of the reinforcing rib 4. It can further improve the strength of the film cover to a certain extent. Since condensate usually gathers at the top of the plastic wrap 1, the drainage strip 5 can guide the condensate to the elastic constriction ring 2 to avoid condensate dripping and contaminating the food.

[0034] Place the food that needs to be preserved, such as leftovers, fruits, and baked goods, into clean containers, such as bowls, plates, or food storage boxes. Ensure that the opening shape is suitable for the film cover, and that there is no excessive splattering of soup on the surface of the food and no oil stains obstructing the mouth of the container, in preparation for the film cover to be applied.

[0035] Hold the elastic retaining ring 2 at the edge of the membrane cover and gently pull it outward. Utilize the extensibility of the elastic retaining ring 2 to unfold the membrane cover as a whole. Align the center of the membrane cover, where the reinforcing rib 4 and the drainage strip 5 converge, with the center of the container above. Adjust the position of the membrane cover so that the reinforcing rib 4 is evenly distributed above the container opening, ensuring that the coverage area is adapted to the container size.

[0036] Slowly lower the film cover, allowing the plastic wrap 1 to hang naturally and cover the container opening. At this time, the elastic gathering ring 2 should fit against the outside or inside of the container opening, adjusting flexibly according to the shape of the container. With the help of the elastic gathering ring 2's rebound force, it will automatically tighten and seal the container opening. Gently pull the edge of the film cover to check the seal: if the elastic gathering ring 2 fits tightly and the film cover has no obvious gaps, the initial seal is complete. At this time, it is important to note that the center of the film cover should also be in the center of the container, which will facilitate the subsequent collection and drainage of condensate.

[0037] After the covering is completed, the antibacterial liner 3 continues to function: relying on the antibacterial properties of zinc oxide nanomaterials, it inhibits the growth of bacteria on the surface of food inside the container and in the air, delaying food spoilage. If the food inside the container has a certain temperature and produces water vapor, condensation will be generated on the inside of the membrane cover. The drainage strip 5 guides the condensation along the surface of the antibacterial liner 3 to the reinforcing rib 4, and finally gathers at the connection between the reinforcing rib 4 and the elastic constriction ring 2 or the edge of the membrane cover, preventing the condensation from dripping directly and contaminating the food, thus ensuring the appearance and taste of the food.

[0038] When you need to take out food, pull the elastic retaining ring 2 in the opposite direction to release the seal and lift the film cover.

[0039] In actual use, the antibacterial liner 3 or reinforcing rib 4 and the drainage strip 5 inside the membrane may come into contact with the food inside the container. At this time, some of the drainage strips 5 may have difficulty playing a drainage role, and condensate may flow directly along the liner or directly into the food. However, the T-shaped structure formed by the drainage strip 5 and the reinforcing rib 4 can still play a basic role in strengthening the membrane.

[0040] This invention effectively improves the strength and quality of the membrane cover by setting the reinforcing rib 4. At the same time, the antibacterial liner 3 can reduce the growth of bacteria and facilitate the preservation of food for a long time. In addition, the setting of the drainage strip 5 can, to a certain extent, divert the condensate generated and reduce the impact of condensate droplets on the food.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
