Description

Technical Field

[0001] This utility model relates to the field of beverage cup technology, specifically to a heat-sealed pure paper lid film for beverage cups, and also to beverage cups. Background Technology

[0002] After beverages are filled, beverage cups need to be sealed with a lid to make them easy to carry. Commonly used lids are plastic sealing film and aluminum foil sealing film. Plastic sealing film has good sealing properties and durability, while aluminum foil sealing film is characterized by its high flatness, easy tearing, and excellent heat sealing effect. Its smooth surface is not conducive to bacterial growth, making it suitable for occasions where maintaining beverage hygiene is important.

[0003] Existing beverage cup sealing films lack heat insulation properties, making it easy for heat to transfer from the cup after cold or hot drinks are poured in, thus affecting the temperature of the beverage and failing to guarantee its optimal taste. Furthermore, existing sealing films lack a gripping structure at the edges, making them difficult to tear. Additionally, when made of plastic or aluminum foil, existing sealing films have weak biodegradability, easily causing environmental pollution. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a heat-sealing pure paper lid film for beverage cups and beverage cups. By setting a double-layer paper lid film and a heat-insulating paper film, the heat-insulating paper film sandwiched in the middle of the beverage cup lid film can play a role in blocking heat transfer, thereby ensuring that the temperature of cold or hot drinks is less affected, thus ensuring the drinking taste, and effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: The beverage cup heat-sealing pure paper lid film includes upper and lower paper lid films. The outer edge of the paper lid film is provided with a reinforcing ring, and a pull ring is provided outside the reinforcing ring. The pull ring is provided with a finger-peeling hole, and an easy-tear paper piece connected to the pull ring by a tear line is provided on the finger-peeling hole. The lower side of the lower paper lid film is coated with a heat-sealing adhesive layer.

[0006] Furthermore, the upper and lower layers of paper cover film are glued together.

[0007] Furthermore, the heat-sealing adhesive layer is applied to the entire lower side of the paper cover film, or the heat-sealing adhesive layer is applied to the lower side of the cover film where the paper contacts the top opening of the paper cup.

[0008] Furthermore, the pull ring and paper cover film are integrated into one structure.

[0009] Furthermore, the inner layer of the central part of the paper cover film has a heat-insulating paper film, which is bonded to the paper cover film.

[0010] Furthermore, a reinforcing rib is provided on the inner side of the reinforcing ring, and the reinforcing rib is bonded to the heat-sealing adhesive layer.

[0011] Furthermore, the paper cover film is provided with straw insertion holes. The paper cover film in the straw insertion hole area is a single layer, that is, the straw insertion hole of the lower layer of paper cover film has a hollow structure.

[0012] A beverage cup includes a paper cup, the top of which is provided with a heat-sealing pure paper lid film as described above, a heat-sealing ring is provided on the upper edge of the paper cup, and two ring grooves are provided on the upper side of the heat-sealing ring. The paper lid film and the heat-sealing ring are connected by heat sealing.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the design of a double-layered paper lid film and a heat-insulating paper film, allows the heat-insulating paper film sandwiched in the middle of the beverage cup lid film to block heat transfer, thereby ensuring that the temperature of cold or hot drinks is less affected, and thus ensuring the taste of the drink.

[0014] This utility model features a pull ring, an easy-tear paper piece, and a tear line. When the paper cover film needs to be torn, the easy-tear paper piece is removed by tearing the tear line, and then a finger is inserted into the hole of the easy-tear paper piece to peel the paper cover film off the paper cup by pulling the pull ring, making it easy to apply force.

[0015] This invention improves the biodegradability of the beverage cup's sealing film in the natural environment by using a double-layered paper lid film, thereby reducing environmental pollution. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 The beverage cup heat-sealed pure paper lid film includes two layers of paper lid film 3. A reinforcing ring 4 is provided on the outer edge of the paper lid film 3. A pull ring 6 is provided on the outside of the reinforcing ring 4. A finger-peeling hole is provided on the pull ring 6. An easy-tear paper piece 7 is provided on the finger-peeling hole and connected to the pull ring 6 by a tear line 8. A heat-sealing adhesive layer 12 is applied to the lower side of the lower paper lid film 3.

[0020] The upper and lower layers of paper cover film 3 are glued together.

[0021] The heat-sealing adhesive layer 12 is applied to the entire lower side of the paper cover film 3, or the heat-sealing adhesive layer 12 is applied to the lower side of the cover film 3 where the paper contacts the top opening of the paper cup 1.

[0022] The pull ring 6 and the paper cover film 3 are an integral structure.

[0023] Among them, the inner layer of the central part of the paper cover film 3 has a heat-insulating paper film 10, and the heat-insulating paper film 10 is bonded to the paper cover film 3.

[0024] Among them, the inner side of the reinforcing ring 4 is provided with a reinforcing rib 11, which is bonded to the heat-sealing adhesive layer 12.

[0025] Among them, the paper cover film 3 is provided with a straw insertion hole 5. The paper cover film in the area where the straw insertion hole 5 is located is a single layer, that is, the lower layer of paper cover film in the area where the straw insertion hole 5 is located has a hollow structure.

[0026] A beverage cup includes a paper cup 1, with a heat-sealing pure paper lid film as described above on the top of the paper cup 1, a heat-sealing ring 2 on the upper edge of the paper cup 1, and two ring grooves 9 on the upper side of the heat-sealing ring 2. The paper lid film 3 and the heat-sealing ring 2 are connected by heat sealing.

[0027] The working principle is as follows: Figures 1-4As shown, the paper lid film 3 and the paper cup 1 are heat-sealed by the heat-sealing ring 2. When inserting a straw, the user inserts the straw into the paper cup 1 through the straw insertion hole 5 to drink the beverage. When it is necessary to remove the paper lid film 3, the easy-tear paper piece 7 is peeled off by tearing the tear line 8, and then the user inserts their finger into the hole at the position of the easy-tear paper piece 7, and then peels off the paper lid film 3 by pulling the ring 6. The heat insulation paper film 10 can improve the heat insulation ability of the paper lid film 3, thereby reducing the heat exchange between the cold or hot beverage in the paper cup 1 and the outside world, thus ensuring that the temperature of the beverage is less affected and ensuring the taste of the beverage. The ring groove 9 can improve the connection strength between the heat-sealing adhesive layer 12 on the paper lid film 3 and the heat-sealing ring 2 after heat sealing, ensuring the airtightness of the beverage cup.
