Description

Technical Field

[0001] This utility model relates to the field of anti-scalding handle technology, and in particular to a folding anti-scalding handle. Background Technology

[0002] With the prevalence of fast-paced lifestyles, instant noodles in cups have become a widely consumed ready-to-eat food due to their convenience. However, existing cup noodle packaging presents significant problems in practical use, including scalding and inconvenience in handling. Traditional instant noodle cups are mostly made of single-layer plastic or paper-plastic composite materials. Although they have some heat insulation properties, after being soaked in hot water, the surface temperature of the cup may still exceed the comfortable contact temperature for the human body (approximately 43°C), causing users to feel hot when holding it. Especially when pouring water, users need to directly contact the hot cup, and the lack of an effective grip structure increases the risk of slipping, unstable pouring, and even burns.

[0003] Furthermore, existing designs are mostly smooth cylindrical structures, which make it difficult to provide a stable point of force application, further exacerbating the inconvenience of operation. Although some products have attempted to improve heat insulation by thickening materials or adding external sleeves, these solutions are often costly or structurally complex, making them difficult to apply on a large scale in fast-moving consumer goods. Therefore, there is an urgent need for an innovative design that is simple in structure, low in cost, and can effectively solve the problems of scalding prevention and grip. Summary of the Invention

[0004] The main objective of this invention is to overcome the shortcomings of existing technologies and provide a foldable anti-scalding handle. This foldable anti-scalding handle design effectively solves the deficiencies of traditional instant noodle buckets in terms of anti-scalding and ease of operation, and has significant market application value and improved user experience.

[0005] The technical solution adopted by this utility model to achieve its technical objective is: a folding anti-scalding handle, including a molding component and two sets of connecting components;

[0006] The shaping component includes a support plate, a bridging plate, and a first folding plate; the bridging plate integrally connects the support plate and the first folding plate.

[0007] The connecting component includes a bonding plate, a second folding plate, and an adhesive plate; the bonding plate integrally connects the second folding plate and the adhesive plate.

[0008] The first folding plate and the second folding plate are integrally connected, and the adhesive plate bonds the two sets of connecting parts together, so that the shaping part and the two sets of connecting parts form a closed loop connection.

[0009] The closed-loop connection of the foldable, heat-resistant handle ensures that the handle fits firmly against the bucket body and prevents it from falling off; the foldable design makes it easy to store and unfold, and can be adapted to different bucket sizes.

[0010] Preferably, the support plate is a rectangular structure, the bridging plate is a trapezoidal structure, and the first folding plate is a right-angled triangle structure, and is symmetrically connected to both sides of the bridging plate.

[0011] The bonding plate 201 is configured as a right-angled trapezoidal structure, and the second folding plate 204 is configured as a right-angled triangular structure. The bonding plate 201 and the second folding plate 204 together form a rectangular structure.

[0012] The rectangular support plate provides a stable contact surface, conforming to the outer curved surface of the barrel. The trapezoidal bridging plate transitions between the support plate and the folding plate, optimizing the distribution of forces. The right-angled triangular symmetrical connection of the first folding plate ensures consistent folding angles on both sides and balanced force distribution. The overall geometric design enhances structural strength, avoids stress concentration, and symmetry ensures handle balance after folding.

[0013] Preferably, a first crease is provided at the connection between the bridging plate and the first folding plate, a second crease is provided at the connection between the bonding plate and the second folding plate, and a third crease is provided at the connection between the first folding plate and the second folding plate. The creases guide precise folding, ensuring structural stability after unfolding and preventing material fatigue or breakage caused by arbitrary bending.

[0014] Preferably, the adhesive plate includes a first adhesive plate, a second adhesive plate, and an adhesive layer; the first adhesive plate is integrally connected to the top of the adhesive plate, and the second adhesive plate is integrally connected to the bottom of the adhesive plate. The double-layer adhesive enhances the fixing force to the barrel body, and the adhesive layer achieves a closed-loop bonding, preventing the handle from loosening.

[0015] Preferably, the adhesive plate is integrally connected to the side of one set of adhesive plates, and the two sets of adhesive plates are glued and fixed together by the adhesive plate. The adhesive plate acts as a "fastener," horizontally bonding the two sets of adhesive plates. This simplifies the assembly process; the user only needs to fold and glue to complete the closed loop, and improves the tensile strength of the connection points.

[0016] Preferably, the overall width of the two sets of connecting parts after bonding is consistent with the width of the molded part. This ensures that the handle width is uniform after the loop is closed, without any local protrusions or depressions. It is aesthetically pleasing and conforms to the curve of the barrel; it also avoids stress concentration caused by uneven width.

[0017] Preferably, it also includes double-sided adhesive, which is applied at the connection point of the two sets of connecting components. The double-sided adhesive adheres to the bonding surface of the adhesive plate. It assists in fixing the adhesive plate, enhancing resistance to longitudinal tensile forces (such as the 5140g load tested in Example 2), and preventing a decrease in adhesive strength at high temperatures.

[0018] Preferably, each component of the shaping part and the connecting part is a foldable semi-rigid sheet material. Semi-rigid sheets are easy to fold and can maintain their shape after unfolding, such as cardboard, combining shaping ability with moderate rigidity. They are low in cost, environmentally friendly, and suitable for disposable use scenarios (such as instant noodle containers).

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This foldable anti-scalding handle enhances scalding performance and safety. The foldable handle design prevents users from directly contacting the hot bucket body, significantly reducing the risk of burns. Furthermore, the handle structure employs a closed-loop connection and double-layer adhesive design to ensure a secure fit to the bucket body, enhancing stability during use.

[0021] This foldable, heat-resistant handle is highly convenient to operate. Its foldable design facilitates storage and unfolding, and it can accommodate different bucket sizes. The introduction of crease lines guides precise folding, ensuring structural stability and preventing material fatigue or breakage caused by arbitrary bending.

[0022] This foldable, heat-resistant handle has a simple and inexpensive structure, using semi-rigid boards (such as cardboard) as the main material. It combines shaping ability with moderate rigidity, is low-cost and environmentally friendly, and is suitable for disposable use. The overall design requires no complex processes and is easy to mass-produce.

[0023] This folding, heat-resistant handle offers high grip stability. The rectangular structure of the support plate and the trapezoidal design of the bridging plate optimize the force distribution, while the symmetrical folding plates ensure balanced force distribution and prevent stress concentration. The handle width matches the body of the container, further enhancing grip comfort and stability. Attached Figure Description

[0036] Please see Figures 1-4 A foldable anti-scalding handle includes a molded part 1, and connecting parts 2 are provided on both sides of the molded part 1;

[0037] The shaping component 1 includes a support plate 101, a bridging plate 102, and a first folding plate 103. The bridging plate 102 is used to integrally connect the support plate 101 and the first folding plate 103. The support plate 101 is configured as a rectangular structure, which facilitates bending and contact with the outer arc surface of the barrel. The bridging plate 102 is configured as a trapezoidal structure, and the first folding plate 103 is configured as a right-angled triangle structure. The first folding plate 103 is symmetrically and integrally connected to both sides of the bridging plate 102. The bridging plate 102 and the first folding plate 103 together form a rectangular structure, and a first crease is provided at the connection between the bridging plate 102 and the first folding plate 103.

[0038] The connecting component 2 includes a bonding plate 201, a second folding plate 204, and an adhesive plate. The bonding plate 201 is used to integrally connect the second folding plate 204 and the adhesive plate. The first folding plate 103 and the second folding plate 204 are integrally connected, and the adhesive plate bonds the two sets of connecting components 2 together, so that the shaping component 1 and the two sets of connecting components 2 form a closed loop connection. The bonding plate 201 is set as a right-angled trapezoidal structure, and the second folding plate 204 is set as a right-angled triangular structure. The bonding plate 201 and the second folding plate 204 together form a rectangular structure, and a second crease is set at the connection between the bonding plate 201 and the second folding plate 204. After the first folding plate 103 and the second folding plate 204 are integrally connected, a third crease is set at the connection between the two. The first folding plate 103 and the second folding plate 204 are symmetrical about the third crease.

[0039] The bonding plate includes a first bonding plate 202, a second bonding plate 203, and an adhesive plate 205. The first bonding plate 202 is integrally connected to the top of the bonding plate 201, and the second bonding plate 203 is integrally connected to the bottom of the bonding plate 201. The connecting parts 2 are symmetrically integrally connected to both sides of the shaping part 1. The adhesive plate 205 is integrally connected to the side of one set of bonding plates 201. After the connecting parts 2 are folded about the side of the shaping part 1 with the second crease facing the second crease, the two sets of bonding plates 201 are bonded and fixed by the adhesive plate 205, so that the shaping part 1 and the two sets of connecting parts 2 form a closed loop connection. After the two sets of connecting parts 2 are bonded, they are located on one side of the shaping part 1.

[0040] After the two sets of connecting parts 2 are bonded together and located on one side of the shaping part 1, the bonding surfaces of the first bonding plate 202 and the second bonding plate 203 both face away from the shaping part 1, and are bonded and fixed to the barrel body through the first bonding plate 202 and the second bonding plate 203. After the two sets of connecting parts 2 are bonded together, their overall width is consistent with the width of the shaping part 1.

[0041] Furthermore, in this embodiment, after the two sets of connecting parts 2 are bonded together and located on one side of the shaping part 1, double-sided adhesive 3 is bonded and fixed at their connection point. The double-sided adhesive 3, together with the first adhesive plate 202 and the second adhesive plate 203, is bonded to the barrel body, making the connection between the connecting parts 2 and the barrel body more stable.

[0042] Furthermore, in this embodiment, the shaping component 1 and its included support plate 101, bridging plate 102, and first folding plate 103, as well as the connecting component 2 and its included bonding plate 201, first adhesive plate 202, second adhesive plate 203, second folding plate 204, and adhesive plate 205, are all made of semi-rigid boards with shaping and shape-changing capabilities, such as foldable cardboard boxes / cartons. The first adhesive plate 202, second adhesive plate 203, and adhesive plate 205 are also made of the aforementioned materials and are integrally coated with an adhesive surface on one side.

[0043] Specifically, in use, to facilitate handling of lightweight containers (such as instant noodle containers) that are heated, and to avoid scalding the hands when handling the container, the entire assembly is bonded to the container body using double-sided adhesive 3 in conjunction with the first adhesive plate 202 and the second adhesive plate 203. Then, the shaping component 1 and the connecting component 2 are opened from the bottom of the bridging plate 102. Due to the setting of the first crease, the second crease, and the third crease, the shaping component 1 and the connecting component 2 can be unfolded according to the angle of the crease. After the shaping component 1 and the connecting component 2 are unfolded, the support plate 101 is pressed against the container body. Example 2

[0044] Please see Figures 1-6Based on the above embodiment, in this foldable anti-scalding handle, the length of the support plate 101 in the molding component 1 is set to 4.5cm, and the width of the first folding plate 103 is set to 5cm. The values ​​of the other components are adaptively set according to the values ​​of the support plate 101 and the first folding plate 103. The bucket that needs to be picked up using the foldable anti-scalding handle is a bucket containing instant noodles and hot water. The following is a specific implementation example:

[0045] In the instant noodle cup, the noodles + ingredients weigh 136g + 6g = 142g;

[0046] Load-bearing capacity verification: When the large cup of instant noodles is filled with water to the mark, the weight of the noodle mixture is 900g. After filling the entire cup with water, the weight of the noodle mixture is 1090g. Since the crease of the folding anti-scalding handle is vertical, and the pressure exerted by the instant noodles on this structure is gravity, it is also a vertical force. Furthermore, the folding anti-scalding handle is secured to the outside of the cup with double-sided tape (or other strong adhesive), thus enabling it to withstand significant vertical forces.

[0047] According to force gauge measurements, the maximum weight that the dual handles can withstand is 5140g, which means they can withstand a longitudinal tensile force of 50.37 Newtons, demonstrating high stability. Therefore, this handle structure can easily withstand the weight of 900g of instant noodle mixture, and after filling the entire instant noodle container with water, the structure can withstand a weight of 1090g.

[0048] This calculation is based on the dimensions of one embodiment of this example. Optionally, if a larger folding structure is used, its load-bearing capacity will continue to increase, but it will cause a certain degree of cost increase and waste of resources.

[0049] The solution in this embodiment can be selectively combined with solutions in other embodiments.

[0050] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural, procedural, or functional transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
