Description

Technical Field

[0001] This utility model relates to the technical field of kraft paper bowl equipment, and in particular to a heat-resistant kraft paper bowl. Background Technology

[0002] In today's fast-paced life, disposable tableware is widely used. Kraft paper bowls, as an important part of this, occupy an important position in the food packaging field, especially in the catering and takeaway industry, due to their environmental protection and biodegradability. Kraft paper bowls have become a common container when people buy hot drinks, hot soups and other foods.

[0003] Currently, traditional kraft paper bowls mostly use a single-layer or simple composite structure. Their main technical principle relies on the material of the kraft paper itself to hold food. Some have an internal waterproof coating to prevent liquid leakage. Structurally, they are basically simple bowl shapes with relatively flat and smooth walls and bottoms.

[0004] However, this traditional kraft paper bowl has a significant problem: when it is filled with hot food, the heat from the food is quickly transferred to the user's hands through the paper bowl, which can easily cause burns. This greatly affects the user experience and poses a safety hazard. Therefore, a heat-resistant kraft paper bowl is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a heat-resistant kraft paper bowl, which aims to improve the problem of heat from food being transferred to the user's hands through the paper bowl during use, thus causing burns to the user's hands.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heat-resistant kraft paper bowl includes a paper bowl, an heat-resistant component provided on the outer wall of the paper bowl, a transparent cover plate provided on the top of the paper bowl, and a stabilizing component provided on the inner wall of the transparent cover plate;

[0008] The anti-scalding component includes a rubber pad one located at the bottom of the paper bowl. The inner wall shape of the rubber pad one matches the shape of the connection between the outer wall and the bottom of the paper bowl. A rubber pad two is provided on the top of the outer wall of the paper bowl. The rubber pad one and the rubber pad two are glued to the paper bowl. Multiple corrugated strips are fixedly connected to the outer wall of the paper bowl, and the outer wall of each corrugated strip is in the shape of a round strip.

[0009] As a further description of the above technical solution:

[0010] The stabilizing component includes multiple locking plates located on both sides of the inner wall of the transparent cover, which engage with the paper bowl.

[0011] As a further description of the above technical solution:

[0012] Both sides of the inner wall of the transparent cover are fixedly connected to connecting frames, and multiple connecting frames are attached to the top of the rubber pad.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the connecting frame has a T-shaped structure, and a card plate is fixedly connected to the bottom of each connecting frame.

[0015] As a further description of the above technical solution:

[0016] The rubber pad has guide grooves on both sides inside, and the card plate fits against the inner wall of the guide groove.

[0017] As a further description of the above technical solution:

[0018] Each of the rubber pads has springs on both sides inside, one end of each spring is fixedly connected to a ball, and the other end of each spring is fixedly connected to the inner wall of the rubber pad.

[0019] As a further description of the above technical solution:

[0020] The ball is slidably connected inside the second rubber pad, and each ball engages with the inside of the plate.

[0021] This utility model has the following beneficial effects:

[0022] In this invention, rubber pads one and two protect the contact surface between the paper bowl and the hand, while corrugated strips slow down the heat transfer rate, achieving the product's anti-scalding effect. This solves the problem of heat from food being transferred to the user's hand through the paper bowl during the use of traditional kraft paper bowls, thus causing burns to the user's hand, and enhances the product's anti-scalding effect.

[0023] In this invention, the position of the card plate is limited by the guide groove, and the connection between the card ball and the inside of the card plate is fixed by the card ball. This solves the problem in traditional products where the transparent cover plate is easily separated from the top of the paper bowl due to too much food or accidental impact from the outside. This enhances the stability of the connection between the transparent cover plate and the paper bowl. Attached Figure Description

[0029] 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.

[0030] Reference Figure 1 An embodiment of this utility model is provided: a heat-resistant kraft paper bowl, including a paper bowl 2, a heat-resistant component provided on the outer wall of the paper bowl 2, a transparent cover plate 1 provided on the top of the paper bowl 2, and a stabilizing component provided on the inner wall of the transparent cover plate 1;

[0031] The anti-scalding component includes a rubber pad 3, located at the bottom of the paper bowl 2. Made of high-temperature resistant rubber, it offers excellent heat insulation and flexibility. The inner wall shape of the rubber pad 3 matches the shape of the connection between the outer wall and bottom of the paper bowl 2, ensuring a tight fit and preventing heat transfer. A second rubber pad 5, also made of high-temperature resistant rubber, is positioned on the top of the outer wall of the paper bowl 2, providing excellent heat insulation and anti-slip properties. Both rubber pads 3 and 5 are glued to the paper bowl 2 to prevent them from falling off during use. Multiple corrugated strips 4 are fixedly connected to the outer wall of the paper bowl 2. These strips are made of food-grade plastic, offering high-temperature resistance and wear resistance. Each corrugated strip 4 has a round outer wall, increasing the thickness and surface area of ​​the paper bowl 2 wall and enhancing its structural strength.

[0032] Specifically, in the process of preventing burns on the product surface, based on the contact area between the user's hand and the bowl when holding it, rubber pad 2 (5) and rubber pad 3 (3) are glued and fixed to the top and bottom of the paper bowl 2, respectively. Rubber pad 2 (5) is located on the outer wall of the top of the paper bowl 2 to isolate the user's hand from direct contact with the top of the paper bowl 2 and prevent heat transfer. Rubber pad 3 is located on the outer wall of the bottom of the paper bowl 2 to isolate the user's hand from direct contact with the bottom of the paper bowl 2, further reducing heat transfer. Through the good heat insulation properties of rubber pad 2 (5) and rubber pad 3 (3), the heat of the food can be effectively blocked from being directly transferred to the user's hand through the paper bowl 2, avoiding burns. Multiple corrugated strips 4 are evenly distributed along the outer wall of the paper bowl 2. The circular shape of the corrugated strips 4 increases the thickness and surface area of ​​the bowl wall, requiring heat to travel through more paths during the transfer process, thereby slowing down the heat transfer speed. The distribution direction and structural design of the corrugated strips 4 can disperse the concentrated heat transfer, further improving the anti-scalding effect and ultimately achieving a good anti-scalding purpose.

[0033] Reference Figures 1-3 The stabilizing component includes multiple retaining plates 8, located on both sides of the inner wall of the transparent cover 1. These plates are made of high-strength plastic, offering wear resistance and deformation resistance. The retaining plates 8 are used to fit against the inner wall of the guide groove 6, ensuring a stable connection between the transparent cover 1 and the paper bowl 2. The transparent cover 1 and the paper bowl 2 are interlocked. The transparent cover 1 is made of transparent polycarbonate, offering high transparency and heat resistance, allowing users to easily observe the food inside the bowl. Connecting brackets 7 are fixedly connected to both sides of the inner wall of the transparent cover 1. These connecting brackets 7 are made of metal, offering high strength and corrosion resistance. Multiple connecting brackets 7 are attached to the top of the rubber pad 5. The outer wall of the connecting bracket 7 has a T-shaped structure to enhance its support and stability. Each connecting bracket 7 has a fixed bottom... A retaining plate 8 is attached, which is used to cooperate with the inner wall of the guide groove 6 to fix the transparent cover plate 1. Guide grooves 6 are opened on both sides of the inner side of the rubber pad 2 5. The guide grooves 6 are made of high temperature resistant rubber material, which has flexibility and wear resistance. The retaining plate 8 fits against the inner wall of the guide groove 6 to ensure that the retaining plate 8 can slide along the inner wall of the guide groove 6. Springs 9 are set on both sides of the inner side of each rubber pad 2 5. The springs 9 are made of high elasticity alloy material, which has fatigue resistance and deformation resistance. One end of each spring 9 is fixedly connected to the outer wall of the retaining ball 10, and the other end of each spring 9 is fixedly connected to the inner wall of the rubber pad 2 5 to provide the restoring force of the retaining ball 10. The retaining ball 10 is slidably connected inside the rubber pad 2 5, and each retaining ball 10 is engaged with the inside of the retaining plate 8.

[0034] Specifically, during the process of placing the transparent cover 1 on top of the paper bowl 2, multiple connecting brackets 7 on the inner wall of the transparent cover 1 are moved to the top of the rubber pad 2 5. At this time, the locking plate 8 will fit against the bottom of the inner wall of the guide groove 6. Next, the transparent cover 1 is rotated, causing the locking plate 8 to move along the inner wall of the guide groove 6 to a specific locking slot. During the rotation and movement of the locking plate 8, the locking plate 8 will push the locking ball 10 to slide into the rubber pad 2 5, while the spring 9 is compressed. When the groove inside the locking plate 8 moves to the bottom of the locking ball 10, the locking ball 10 loses the squeezing force of the locking plate 8. The rebound force of the spring 9 pushes the locking ball 10 to engage with the groove inside the locking plate 8, thereby fixing the position of the locking plate 8. This process solves the problem in traditional products where the transparent cover 1 separates from the top of the paper bowl 2 due to excessive food or external impact after being placed on top of the paper bowl 2. Through the cooperation of the locking plate 8, the locking ball 10 and the spring 9, the stability of the connection between the transparent cover 1 and the paper bowl 2 is enhanced, ensuring safety during use.

[0035] Working principle: During the anti-scalding process on the product surface, based on the contact area between the user's hand and the bowl when holding it, rubber pads 2 and 3 are glued to the top and bottom of the paper bowl 2 respectively. Through the good heat insulation properties of rubber pads 2 and 3, the contact area between the user's hand and the surface of the paper bowl 2 is well insulated, preventing the heat of the food from being directly transferred to the user's hand through the paper bowl 2 and causing burns. In addition, multiple corrugated strips 4 are used to increase the thickness and surface area of ​​the bowl wall, so that the heat needs to go through more paths during the heat transfer process, thereby slowing down the heat transfer speed and ultimately achieving a good anti-scalding effect.

[0036] During the process of covering the paper bowl 2 with the transparent cover 1, the multiple connecting brackets 7 on the inner wall of the transparent cover 1 are moved to the top of the rubber pad 2 5. At this time, the locking plate 8 will move to fit against the bottom of the inner wall of the guide groove 6. Next, the transparent cover 1 is rotated so that the locking plate 8 moves to a specific locking groove. During the rotation and movement of the locking plate 8, the locking ball 10 will be pushed to slide into the rubber pad 2 5, and the spring 9 will be compressed. When the groove inside the locking plate 8 moves to the bottom of the locking ball 10, the locking ball 10 loses the squeezing force of the locking plate 8 and will use the rebound force of the spring 9 to push the locking ball 10 to engage with the groove inside the locking plate 8, thereby fixing the position of the locking plate 8. This solves the problem in traditional products where the transparent cover 1 is easily separated from the top of the paper bowl 2 due to too much food or accidental external impact, thus enhancing the stability of the connection between the transparent cover 1 and the paper bowl 2.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
