Description

Technical Field

[0001] This invention belongs to the field of packaging box technology, and in particular relates to a heat-proof and oil-proof sandwich packaging box for freshly fried snacks. Background Technology

[0002] Freshly fried snacks, as the name suggests, are snack foods that are fried on-site using edible oil, such as: French fries, fried dough sticks, twisted dough sticks, potato chips, tofu, instant noodles, fried chicken, fried fish, fried shrimp, fried chicken strips, fried chicken neck bones, fried rice cakes, fried gluten, fried pork belly, etc. There are many varieties. After the freshly fried snacks are fried, they need to be packaged in bags.

[0003] The existing technology (patent application CN211845376U, entitled "A Moisture-proof Food Recycling Box for Fried Foods") addresses the problem that existing fried food packaging boxes lack moisture-proof functionality, have poor moisture-proof effects, thus affecting storage and consumption, and are not recyclable. In implementing this technical solution, at least the following problems were found in the existing technology: After the fried snacks are fried, vendors usually use disposable plastic bags or kraft paper bags to hold them. Because the snacks absorb a lot of cooking oil after frying, and vendors are usually busy and don't let the oil cool down for long, the absorbed oil gradually seeps out. The high temperature generated during frying causes the hot snacks, along with the residual oil, to burn and leak from the disposable plastic bags and cause prolonged oil seepage from the kraft paper bags, affecting the consumer's eating experience. Summary of the Invention

[0004] This application aims to at least address one of the technical problems of oil leakage in traditional packaging bags in the prior art. To this end, this application proposes a heat-resistant and oil-leakage-resistant sandwich-type packaging box for freshly fried snacks.

[0005] To achieve the above objectives, the specific technical solution of the present invention is as follows: A heat-resistant and oil-proof sandwich-type packaging box for freshly fried snacks includes a plastic box body, characterized in that: a plastic box lid is snapped onto the plastic box body, and a heat-resistant component matching the plastic box lid is provided on the outside of the plastic box body; The anti-scalding component includes a buckle seat fixed to the outside of the plastic box, and a handle head is snapped into the buckle seat. Two sets of the handle heads are fixed with thick iron wires. Plastic support feet are fixed around the bottom of the plastic box, and an oil leakage component is provided inside the plastic box to match the plastic support feet. The oil leakage component includes an oil leakage plate embedded in the side of the plastic box near the plastic support feet, and an oil leakage port is opened on the oil leakage plate. The bottom end of the oil leakage plate is connected to an oil guide head that seals the interlayer cavity. The oil leakage component is equipped with an opening and closing component.

[0006] Preferably, the tops of the two sets of thick iron wires are hinged with universal joints that are fixed to the plastic box body, and the two sides of the plastic box cover are each provided with limiting blocks that connect with the thick iron wires.

[0015] The heat-resistant and oil-proof sandwich-type packaging box for freshly fried snacks of the present invention has the following advantages: 1. This heat-resistant and oil-proof sandwich-type packaging box for freshly fried snacks uses heat-resistant components to facilitate lifting the plastic box body and plastic lid as a whole, preventing direct contact with the plastic box body and plastic lid containing the freshly fried food and causing burns. At the same time, it insulates the high temperature of the freshly fried snacks inside the plastic box, preventing heat conduction to the outside of the plastic box and causing burns, while also playing a heat preservation role.

[0016] 2. This heat-proof and oil-proof sandwich-type packaging box for freshly fried snacks uses an oil-leaking component to direct the edible oil dripping from the freshly fried snacks inside the plastic box to the oil guide head area, and temporarily collects and stores the oil in the oil storage cavity.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments: like Figures 1-10 As shown, the present invention provides a heat-resistant and oil-proof sandwich-type packaging box for freshly fried snacks, comprising a plastic box body 1, a plastic box lid 2 snapped onto the plastic box body 1, and both the plastic box body 1 and the plastic box lid 2 being made of lightweight heat-resistant composite plastic material. While reducing the overall weight of the plastic box 1 and the plastic lid 2, it also improves the overall heat resistance of the plastic box 1 and the plastic lid 2, so as to avoid the residual heat carried by the plastic box 1 and the plastic lid 2 from being scalded, deformed, or even broken and leaking oil when they are filled with fried snacks. Furthermore, the outer side of the plastic box body 1 is provided with an anti-scalding component that matches the plastic box lid 2. The anti-scalding component includes a buckle seat 71 fixed to the outer side of the plastic box body 1, and a handle head 72 is snapped into the buckle seat 71. Two sets of handle heads 72 are fixed with thick iron wires 73. The handle head 72 in its initial position is locked in place by the buckle seat 71, which prevents the handle head 72 from shaking and affecting the serving of freshly fried snacks when there is no need to lift and move the plastic box 1 and the plastic box lid 2. By using thick iron wire 73 instead of the traditional soft nylon rope design, if the fried snacks in the plastic box 1 are not full and the force is uneven, the traditional soft nylon rope design will easily cause the plastic box 1 to tilt, and tilt towards the side containing the fried snacks. The design using thick iron wire 73 can provide overall support for the plastic box 1, ensuring that the plastic box 1 remains stable when lifted and moved, whether it is not full or full of freshly fried snacks, which also facilitates subsequent oil draining operations. The top of the two sets of thick iron wires 73 is hinged with universal joints 74 that are fixed to the plastic box body 1. Through the universal joints 74, universal rotation support is provided for the flipping shape of the thick iron wires 73, which makes it easier for the thick iron wires 73 to flip with the handle head 72 to the lifting position above the plastic box cover 2. And the two sides of the plastic box cover 2 are both embedded with limiting blocks 75 that connect with the thick iron wires 73. The limiting block 75 serves to stop the thick iron wire 73 from flipping upwards into place. An arc-shaped chamfer is provided at the edge of the limiting block 75 to reduce frictional wear between the thick iron wire 73 and the limiting block 75, extend the service life of the thick iron wire 73, and enable it to be used continuously. The handle head 72, thick iron wire 73, and universal head 74 make it easy to lift the plastic box body 1 and plastic box lid 2 as a whole, so as to prevent direct contact with the plastic box body 1 and plastic box lid 2 containing freshly fried food, which could cause burns.

[0022] The plastic box 1 has a double-layer cavity 76 inside. The double-layer cavity 76 insulates the high temperature of the fried snacks inside the plastic box 1, preventing heat from being conducted to the outside of the plastic box 1 and causing burns, while also keeping it warm. Furthermore, the plastic box body 1 is provided with a mating groove 3, and a mating protrusion 4 that is fixed to the plastic box lid 2 is engaged in the mating groove 3. Through the mating groove 3 and the mating protrusion 4, the plastic box lid 2 can be stably engaged on the plastic box body 1, which not only forms a sealing and protection for the plastic box body 1, but also slows down the loss of residual heat from the various freshly fried snacks contained in the plastic box body 1, thus playing a role in sealing, heat preservation and dust prevention.

[0023] like Figures 1-10 As shown, plastic support legs 11 are fixed around the bottom of the plastic box 1, and an oil leakage component that matches the plastic support legs 11 is provided inside the plastic box 1. The plastic box 1 has observation windows 5 on all four sides. The observation windows 5 are sealed to the interlayer cavity 76. Through the observation windows 5, it is easy to observe the state of the freshly fried snacks inside the plastic box 1 from the outside. The observation windows 5 are also equipped with heat-insulating soft glass. The heat-insulating soft glass keeps the material transparent, which is conducive to observation and also reduces costs. The plastic box 1 is equipped with a cross-shaped heat insulation partition 6. The cross-shaped heat insulation partition 6 divides the plastic box 1 into four placement areas and insulates the residual heat carried by the fried snacks placed in each placement area. It also prevents different types of fried snacks from mixing flavors. The plastic box 1 has an inclined surface 8 at the bottom near the heat insulation partition 6. The height of the inclined surface 8 decreases gradually from the inside to the outside. When the cooking oil remaining on the fried snack drips to the bottom of the plastic box 1, it flows quickly to the oil drainage area through the inclined surface 8, which decreases gradually from the inside to the outside, to prevent the dripping cooking oil from accumulating at the bottom of the plastic box 1 and causing oil leakage. Furthermore, a placement plate 9 is fixed on the side of the plastic box 1 near the inclined surface 8. The placement plate 9 facilitates the placement of various freshly fried snacks. An oil filter 10 is embedded in the inner side of the placement plate 9. The oil filter 10 filters the residual cooking oil on the freshly fried snacks and intercepts the food scraps that flow out with the cooking oil, so as to avoid subsequent oil drainage blockage. The height of the placement plate 9 and the oil filter screen 10 increases gradually from the inside to the outside, and the direction of the tilt distribution is opposite to that of the tilted surface 8. This tilting effect helps to control the oil in various fried snacks placed on the placement plate 9, making it easier to quickly drain the residual cooking oil in the fried snacks, reducing the amount of cooking oil residue in the fried snacks, and at the same time reducing the intake of cooking oil, which is healthier. The oil leakage component includes an oil leakage plate 121 embedded in the plastic box 1 near the plastic support 11, and the oil leakage plate 121 has oil leakage outlets 122 in a triangular equidistant shape. The bottom end of the oil leakage plate 121 is connected to an oil guide head 123 that is sealed to the interlayer cavity 76. Through the oil leakage plate 121 and the oil leakage outlets 122, the edible oil dripping from the fried snacks in the plastic box 1 flows to the area of ​​the oil guide head 123, completing the flow and drainage of the edible oil dripping from the fried snacks, reducing the amount of edible oil accumulated in the bottom area of ​​the plastic box 1, concentrating the drainage of oil, and preventing oil seepage. The plastic support leg 11 has an oil storage cavity 124 that communicates with the oil guide head 123. The dripping waste cooking oil is temporarily stored and collected through the oil storage cavity 124 in the plastic support leg 11. Furthermore, a sealing screw groove 125 is provided at the bottom of the oil storage cavity 124, and a sealing screw head 126 is connected to the sealing screw groove 125 internally. Through the sealing screw groove 125 and the sealing screw head 126, the oil storage cavity 124 is sealed, and it is also convenient to periodically pour the edible waste oil collected in the oil storage cavity 124 to the cleaning area, preventing oil leakage and allowing for reuse.

[0024] like Figures 1-10 As shown, the oil leakage assembly is equipped with an opening and closing assembly, which includes a sealing cover 131 that is snapped onto the oil leakage plate 121. The bottom of the sealing cover 131 is fixed with a sealing block 132 that snaps onto the oil leakage port 122 in a triangular equidistant shape. The oil leakage port 122 on the oil leakage plate 121 is blocked by the sealing block 132 on the sealing cover 131, forcing the oil leakage port 122 to close its oil discharge channel. A heat-conducting hole 133 is provided on the circumference of the sealing cover 131, and a heat-conducting cavity 134 communicating with the heat-conducting hole 133 is provided inside the sealing cover 131. A sliding end 135 is connected to the bottom end of the heat-conducting cavity 134, so that the residual heat and high temperature of the fried snacks contained in the plastic box 1 can be conducted through the heat-conducting hole 133 and the heat-conducting cavity 134, and then through the sliding end 135. The oil drain plate 121 has a sliding cavity 136 that slides with the sliding end 135. The residual heat and high temperature carried by the fried snack are conducted to the sliding cavity 136 through the sliding end 135. The heat conduction cavity 134 is interconnected with the sliding cavity 136 through the sliding end 135. A memory metal block 137 that fits with the sliding end 135 is placed vertically in the sliding cavity 136. The residual heat and high temperature carried by the fried snack are conducted to the memory metal block 137 through the sliding cavity 136, causing it to expand and deform, providing a purely mechanical lifting force.

[0025] Using the memory metal block 137, based on the principle of thermal expansion and contraction, a purely mechanical pushing and pulling method is adopted to open and close the oil leakage port 122 on the oil leakage plate 121 at a frequency by the sealing block 132 on the sealing cover 131. When thermal expansion occurs, the sealing block 132 is removed from the oil leakage port 122. When the oil is cooled and contracted, the sealing block 132 engages with the oil leak port 122, thus closing the oil drain channel. This adaptively opens and closes the drain channel and adjusts the size of the opening and closing to accommodate the residual edible oil in the fried snacks, following the changes in residual heat.

[0026] Working principle: First, place the freshly fried snacks into the four placement areas formed by the cross-shaped heat insulation partition 6 on the placement plate 9. Then, snap the plastic box lid 2 onto the plastic box 1. Next, snap the two sets of handle heads 72 off the buckle seat 71 and flip them to face each other above the plastic box lid 2. With the universal head 74 providing universal rotation to the thick iron wire 73, the two sets of handle heads 72 synchronously drive the two thick iron wires 73 to flip and connect with the limit block 75 until the two sets of handle heads 72 are flipped above the plastic box lid 2. Then, grip the two sets of handle heads 72 tightly and lift the plastic box 1 and the freshly fried snacks inside to move it. The interlayer cavity 76 inside the plastic box 1 provides heat insulation for the various freshly fried snacks on the four placement plates 9. During this period, the various fried snacks placed on the four placement plates 9 have residual cooking oil. This oil drips through the oil filter screens 10 on the four tilted placement plates 9 and onto the inclined surfaces 8 at the bottom of the four placement areas. The oil then flows quickly to the oil drain plate 121 area and through the oil drain 122 and the oil guide head 123 to the oil storage chamber 124 in the plastic support 11 for temporary storage and collection. The sealing screw head 126 is periodically unscrewed from the sealing screw groove 125. The waste cooking oil in the oil storage chamber 124 is discharged to the waste oil cleaning area through the channel opened by the sealing screw groove 125. Then, the plastic box cover 2 is opened to clean the inside of the plastic box 1, which can be reused. At the same time, when the residual heat of the various fried snacks placed on the four placement plates 9 is high, it is introduced into the heat conduction cavity 134 inside the sealing cover 131 through the heat conduction hole 133 on the sealing cover 131, and then through the sliding end 135 to the memory metal block 137 area in the sliding cavity 136. Based on the principle of thermal expansion, the memory metal block 137 expands and deforms after being heated, and forces the sliding end 135 to rise upward in the sliding cavity 136. Then, the upwardly rising sliding end 135 drives the sealing block 132 on the sealing cover 131 to separate from the oil leak port 122 on the oil leak plate 121, that is, the channel of the oil leak port 122 is opened. Conversely, when the residual heat carried by the various fried snacks placed on the four placement plates 9 is low, based on the principle of cold contraction, the residual heat is conducted sequentially from the heat conduction hole 133 and heat conduction cavity 134 through the sliding cavity 136 to the memory metal block 137 area. Then, the memory metal block 137 shrinks and resets, forcing the sliding end 135 to be pulled down in the sliding cavity 136. Then, the sliding end 135 pulled down drives the sealing block 132 on the sealing cover 131 to re-lock onto the oil leak port 122 on the oil leak plate 121, that is, the channel of the oil leak port 122 is closed.
