Description

Technical Field

[0001] The utility model belongs to the technical field of disposable tableware, and particularly relates to a heat-insulating and non-slip disposable tableware. Background Art

[0002] Disposable tableware can encapsulate meals and has a certain degree of heat preservation, giving people more choices when dining out. In order to reduce costs, disposable tableware is mostly made of easily recyclable materials, such as polypropylene (PP), high-impact polystyrene (HIPS), biaxially oriented polystyrene (BOPS), etc.

[0003] Disposable tableware is generally thinner and has poor heat insulation. When it is used to hold hot food, it is easy to burn your hands. Therefore, traditional disposable tableware is modified into a box or bowl shape with an insulating cavity inside to separate the hands from the hot inner wall. Disposable tableware is mostly packaged in degradable cardboard, which is rougher and less slippery than plastic packaging such as polypropylene.

[0004] Existing disposable tableware is generally carried in a degradable cardboard shell. The surface of the cardboard shell is raised for heat insulation, but the cardboard shell is easily flattened, especially when it is stacked and squeezed during the delivery process of takeout. If a handle is added to the cardboard shell, the handle needs to extend to both sides to leave enough insulation distance. Using the handle for heat insulation and anti-slip also takes up more space. For this reason, we propose a heat-insulating and anti-slip disposable tableware. Utility Model Content

[0005] The utility model aims to provide a heat-insulating and non-slip disposable tableware. Two handles are folded vertically or unfolded horizontally outside the heat-insulating paper cover to play the role of heat insulation and non-slip, and the space is saved and it is convenient to stack or squeeze.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A heat-insulating and non-slip disposable tableware comprises a dining bowl, both sides of which are fixed with heat-insulating paper sleeves, and the other two sides of the dining bowl are fixed with hinged seats, and the two hinged seats each comprise a concave block and a pin shaft rotatably connected to the concave block, and two handles are arranged on the outside of the dining bowl, and the two handles are in the shape of straight rods with one end being annular, and the annular parts of the two handles extend into the interior of adjacent concave blocks and are sleeved on the outside of the pin shaft, and the upper edges of the two handles near the concave blocks are fixed with connecting plates, and the central axis of the connecting plates is parallel to the central axis of the handles, and the upper surfaces of the two concave blocks are provided with a card slot adapted to one end of the connecting plate, and when serving food, the two handles are placed around the pin shafts of the adjacent hinged seats with the two handles facing downward. The bowl can be folded and placed against the outside of the bowl to save space. The lid can be opened, and the meal can be put into the bowl. The lid can be closed and pressed tightly to facilitate stacking or squeezing in containers such as thermal insulation boxes. Two handles and two heat-insulating paper sleeves can be used as protective layers on the outside to support the bowl and prevent it from being crushed and spilled. When eating, the two handles can be flipped upward around the hinged seat to drive the connecting plate to be inserted into the slot and fit with interference. The friction can be used to lock the two handles so that the two handles are suspended horizontally on adjacent hinged seats. The two handles can be held by hand to move the bowl away from the meal, which can play a role in heat insulation and scalding prevention. The rough surfaces of the two heat-insulating paper sleeves can contact the placement surface or hands, which can insulate and prevent slipping.

[0008] Both ends of the two heat-insulating paper sleeves are integrally installed with paper support plates, which are parallel to the handles. A clamping groove is formed between two adjacent paper support plates, which can be interference-fit with the adjacent handles. After the handles are inserted, the handles are locked by friction to prevent the handles from swinging during transportation or carrying.

[0009] Hollow protrusions are arranged at intervals on the two insulation paper sleeves, and several of the hollow protrusions surround the dining bowl. Several hollow protrusions increase the complexity of the insulation paper sleeve structure to enhance the supporting strength of the protective layer, and air can flow inside the hollow protrusions to take away the heat of the insulation paper sleeve for heat dissipation, thereby enhancing the insulation performance.

[0010] A plurality of heat dissipation holes are arranged at intervals on the outside of the two handles, and the heat dissipation holes can circulate air to take away the heat of the handles for heat dissipation, thereby enhancing the heat insulation performance.

[0011] Several metal rings are arranged inside the two handles, and the outer surfaces of the metal rings are fixedly connected to the inner walls of the heat dissipation holes. The metal rings serve as an inner skeleton to support the inside of the handles to prevent the handles from bending, so as to cooperate with the hinged seat to stably support the dining bowl.

[0012] A glass fiber wool board is fixed on the side of the two recessed blocks that are away from each other. After the handle is suspended horizontally, the glass fiber wool board is used as an interlayer between the handle and the hinge seat to reduce heat conduction, so as to block the heat transferred from the bowl to the handle, thereby keeping the handle at a low temperature and preventing burns.

[0013] The technical effects achieved by this utility model are:

[0014] The utility model discloses a heat-insulating and non-slip disposable tableware. When serving food, two handles are swung downward around the pin shafts of adjacent hinged seats and folded against the outer side of the bowl, which saves space. The lid is opened, and the food is put into the bowl, and then the lid is closed and pressed tightly, so that the tableware can be conveniently placed in containers such as an incubator for stacking or squeezing. The two handles and two heat-insulating paper sleeves are arranged on the outer side as protective layers to support the bowl, so as to prevent the bowl from being flattened and causing leakage. When dining, the two handles can be flipped upward around the hinged seats, and the connecting plate can be driven to be inserted into the card slot and interference fit, and locked by friction, so that the two handles are horizontally suspended on the adjacent hinged seats. The two handles can be held by hand to move the bowl to a position away from the food, so as to play a role of heat insulation and scalding prevention. The rough surfaces of the two heat-insulating paper sleeves contact the placement surface or the hands, so as to provide heat insulation and non-slip. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-4As shown, a heat-insulating and non-slip disposable tableware includes a dining bowl 1, a lid is clamped at the opening of the dining bowl 1, and both the dining bowl 1 and the lid can be made of photobiodegradable PP, polypropylene (PP), high-impact polystyrene (HIPS), biaxially oriented polystyrene (BOPS) or natural inorganic mineral-filled polypropylene composite materials, etc., insulation paper sleeves 2 are fixed on both sides of the dining bowl 1, and both insulation paper sleeves 2 can be made of degradable paper products with good structural strength, and hinge seats 3 are fixed on the other two sides of the dining bowl 1, and the two hinge seats 3 both include concave blocks and pins rotatably connected to the concave blocks. Two handles 4 are arranged on the outside of the dining bowl 1, and the two handles 4 are straight rods with one end being annular, and the annular parts of the two handles 4 extend into the adjacent concave blocks and are sleeved on the outside of the pins, and the two handles 4 are fixed with connecting plates 5 near the upper edges of the concave blocks, and the two handles 4, the two hinge seats 3 and the connecting plate 5 can be made of disposable degradable plastic materials, and the central axis of the connecting plate 5 is parallel to The central axis of the handle 4, the upper surfaces of the two concave blocks are provided with a card slot 6 adapted to one end of the connecting plate 5. Before leaving the factory, the bowl 1 and the lid are sterilized. When the meal is filled, the two handles 4 are swung downward around the pins of the adjacent hinge seats 3 and folded against the outside of the bowl 1, which saves space. The lid is opened, the meal is put into the bowl 1, and then the lid is closed and pressed, which is convenient for stacking or squeezing in containers such as incubators. The two handles 4 and the two insulation paper sleeves 2 are on the outside. The protective layer supports the dining bowl 1 to prevent the dining bowl 1 from being flattened and causing spillage. When eating, the two handles 4 can be flipped upward around the hinge seat 3 to drive the connecting plate 5 to be inserted into the slot 6 and interference fit, and locked by friction, so that the two handles 4 are horizontally suspended on the adjacent hinge seats 3. The two handles 4 can be held by hand to move the dining bowl 1 to a position away from the meal, which can play a role in heat insulation and scalding prevention. The rough surfaces of the two insulation paper sleeves 2 contact the placement surface or hands, which can insulate and prevent slipping.

[0023] Among them, the thickness of the two handles 4 and the thickness of the two hinged seats 3 are both greater than 1.5 mm, maintaining good structural strength. Even if used to support the bowl 1 filled with food, the shape can be maintained without deformation. When the two handles 4 are placed vertically, they are close to the outside of the bowl 1 and occupy less space horizontally. Even if part of the heat of the bowl 1 is conducted to the vertically placed handles 4, the handles 4 are subsequently suspended horizontally away from the bowl 1, and the heat can be dissipated into the air to reduce their own temperature.

[0024] like Figure 1 and Figure 2 As shown, both ends of the two heat-insulating paper sleeves 2 are integrally installed with paper support plates 7, and the paper support plates 7 are parallel to the handles 4. A clamping groove is formed between two adjacent paper support plates 7, which can be interference-fitted with the adjacent handles 4. After the handles 4 are inserted, the handles 4 are locked by friction to prevent the handles 4 from swinging during transportation or carrying.

[0025] like Figure 1 and Figure 2 As shown, hollow protrusions 8 are arranged at intervals on the two insulation paper sleeves 2, and the hollow protrusions 8 are integratedly installed in the insulation paper sleeves 2. Several hollow protrusions 8 surround the dining bowl 1. Several hollow protrusions 8 increase the complexity of the structure of the insulation paper sleeve 2 to enhance the supporting strength of the protective layer, and air can circulate inside the hollow protrusions 8 to take away the heat of the insulation paper sleeves 2 for heat dissipation, thereby enhancing the insulation performance.

[0026] like Figure 1 and Figure 4 As shown, a plurality of heat dissipation holes 9 are provided at intervals on the outside of the two handles 4. The heat dissipation holes 9 can circulate air to take away the heat of the handles 4 for heat dissipation, thereby enhancing the heat insulation performance.

[0027] like Figure 1 and Figure 4 As shown, a plurality of metal rings 10 are provided inside the two handles 4, and the outer surfaces of the metal rings 10 are fixedly connected to the inner walls of the heat dissipation holes 9. The metal rings 10 serve as an internal skeleton to support the inside of the handles 4 to prevent the handles 4 from bending, so as to cooperate with the hinge seat 3 to stably support the dining bowl 1.

[0028] like Figure 1 and Figure 3 As shown, a glass fiber wool board 11 is fixed on one side of the two recessed blocks away from each other. After the handle 4 is suspended horizontally, the glass fiber wool board 11 is used as an interlayer between the handle 4 and the hinge seat 3 to reduce heat conduction, and is used to block the heat transferred from the bowl 1 to the handle 4, so as to keep the handle 4 at a low temperature and prevent burns.

[0029] The working principle of the utility model is as follows: when serving food, the two handles 4 are swung downward around the pin shafts of the adjacent hinged seats 3 and folded against the outer side of the bowl 1, which saves space. The lid is opened, and the food is put into the bowl 1, and then the lid is closed and pressed tightly, so that it is convenient to stack or squeeze in containers such as an incubator. The two handles 4 and the two heat-insulating paper sleeves 2 serve as a protective layer on the outer side to support the bowl 1 to prevent the bowl 1 from being crushed and causing leakage.

[0030] When eating, the two handles 4 can be flipped upward around the hinge seat 3, driving the connecting plate 5 to insert into the slot 6 and interference fit, and locked by friction, so that the two handles 4 are horizontally suspended on the adjacent hinge seats 3. The two handles 4 can be held by hand to move the bowl 1 to a position away from the meal, which can play a role in heat insulation and scalding. The rough surfaces of the two insulation paper covers 2 contact the placement surface or the hand, which can insulate and prevent slipping.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
