Description

Technical Field

[0001] The utility model is applied to the field of food and relates to food packaging, in particular to a packaging box for heating flower steamed buns. Background Art

[0002] Huamo is an artistic food that reflects Chinese culture in terms of diet. It is eaten during festivals, birthdays, weddings, funerals, etc., and is used to express ideals and wishes. After the ceremony, it is often enjoyed as a delicacy. The Huamo prepared in advance has a low temperature, especially in winter, and the taste is very poor. However, there is no suitable heating vessel on site. Even in a restaurant, the size of the microwave oven in the restaurant may not correspond to the size of the Huamo. For this reason, when customizing Huamo, it is particularly important to provide a packaging box that can be self-heated on site, which can even lead the market trend.

[0003] There are many patent applications for self-heating food boxes, including CN105836307A, a self-heating packaging container, CN109095007A, a self-heating fresh cold chain packaging box, CN109649854B, a self-heating food packaging box, CN204433418U, a self-heating packaging box, CN209080637U, a self-heating packaging box, and CN204056752U, a portable self-heating packaging box, etc. This application not only needs to meet the self-heating function and solve customer difficulties, but also needs to be easy to operate and enhance customer experience, while not destroying the artistic beauty of the flower bun. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a self-heating flower steamed bun packaging box, which adopts a heating bag for self-heating, is simple to operate, convenient to pack, and does not destroy the artistic beauty of the flower steamed bun.

[0005] The technical solution adopted by the utility model is: the self-heating flower steamed bun packaging box includes a box cover, a grating plate, a bottom box, and a packaging frame. The packaging frame is installed on the grating plate and includes a pressure rod, a baffle, a puncture hole, and a packaging groove. The pressure rod passes through the ventilation square hole on the grating plate and is positioned by the ventilation square hole. The baffle is fixed on the outer surface of the pressure rod, contacts the grating plate, fixes the packaging frame, and prevents the packaging frame from moving down. The packaging groove is fixed at the bottom of the pressure rod, and a heating pack is placed, which corresponds to the size of the heating pack. The puncture hole is processed on the packaging groove, and corresponds to the sharp protrusion at the bottom of the bottom box. When the sharp protrusion passes through the puncture hole, the heating pack can be destroyed, so that the self-heating material contacts water, and the exothermic reaction generates water vapor to heat the flower steamed bun. The lower opening of the box cover is buckled with the upper opening step of the bottom box, and a vent is processed on the buckling surface of the box cover. The vent forces the steam to go down, ensuring that the flower steamed bun is heated evenly, while preventing dust in the air from falling into the packaging box and contaminating the flower steamed bun.

[0006] Furthermore, the grating plate and the bottom box are positioned and installed by cooperating with a positioning protrusion and a positioning notch. The positioning notch is arranged on the outer edge of the grating plate, and the positioning protrusion is arranged on the inner surface of the upper opening of the bottom box, laying a positioning foundation for the cooperation between the sharp protrusion and the puncture hole.

[0007] Furthermore, the top inner surface of the box cover is an inclined surface, such as a hemispherical, semi-ellipsoidal, or other inclined surface shapes. Water droplets flow down along the inner surface of the box cover to the bottom box and will not drip onto the flower steamed bun, thereby not destroying the artistic beauty of the flower steamed bun.

[0008] Furthermore, a handle is designed on the top of the box cover to facilitate opening the box cover. A reinforcing ring is designed at the bottom of the box cover to help maintain the roundness of the lower opening of the box cover and facilitate buckling with the upper opening of the bottom box.

[0009] Furthermore, the thickness of the grating plate at the ventilation square hole position is greater than that at other positions, that is, the hole depth of the ventilation square hole is greater than the hole depth of the ventilation hole on the grating plate, ensuring that the displacement of the pressure rod is small when it moves downward, and the puncture hole and the sharp protrusion can be positioned and matched.

[0010] Furthermore, a fixed boss is provided on the inner surface of the upper opening of the bottom box, and the boss is a full ring or evenly distributed, and is used to support and fix the grating plate.

[0011] Furthermore, a sealing paper is fixed on the inner surface of the bottom box, and the sealing paper seals the water. The height of the water is higher than the sharp protrusion, so as to avoid spilling during transportation and enhance the customer experience.

[0025] The packaging box structure of the flower bun in this embodiment is as shown in the attached figure. Figure 1-4 As shown, it includes a box cover 1, a grating plate 2, a wrapping frame 3, a bottom box 4, etc. The grating plate 2 is placed on the top of the bottom box 4 to hold the flower buns, and the box cover 1 is buckled on the bottom box 4 to seal the flower buns. The wrapping frame 3 is installed on the grating plate 2, and a heating bag is placed at the bottom. Pure water is placed at the bottom of the bottom box 4. When the heating bag moves down and contacts the pure water, the hot water evaporates, realizing the steam self-heating of the flower buns.

[0026] The lid 1 is a cylindrical structure with a hemispherical upper portion. Figure 1 As shown. In order to prevent the self-heating water vapor from condensing and dripping on the flower bun, causing bubble defects on the surface of the flower bun and affecting the artistic beauty of the flower bun, the top is designed to be hemispherical, so that the condensed water droplets can slide down the hemispherical inner wall and then fall into the bottom box 4 from the cylindrical inner wall. In order to ensure that the water droplets slide off the inner surface of the box cover, the box cover should be made of a material with good water infiltration ability, such as glass, plastic, etc., and the plastic should be transparent plastic. In this way, the glass or plastic is transparent, and the flower bun can still be seen without opening the packaging box, which does not affect the sense of ceremony. Especially for outdoor environments, the flower bun can be protected from dust pollution, kept clean, and eaten with confidence. The top of the box cover is designed with a handle 11, which is convenient for opening the box cover 1 and avoiding scalding. For the plastic box cover, due to its strong elastic deformation ability, a reinforcing ring 12 can be designed at its lower part to ensure the roundness of the lower mouth of the box cover, which is convenient for buckling with the bottom box 4. The lower opening of the box cover is buckled with the upper opening step of the bottom box 4, as shown in the attached Figure 4As shown, to ensure the positioning and stability of the box lid. An air vent 13 is processed on the lower snap-fitting surface of the box lid, and the box lid and the bottom box are snap-fitted. The air vent 13 can dissipate the steam in the box lid. The other positions of the box lid are closed, and only the position snapped with the bottom box is connected to the atmosphere. When the bottom box generates steam to heat the flower bun, the steam goes up. When the air vent 13 emits steam, it means that the steam is fully diffused in the box lid, ensuring that the steam is evenly heated from top to bottom of the flower bun. At the same time, the air vent 13 is set at this position, which can effectively prevent the strong wind in the ritual environment from bringing dust into the packaging box to contaminate the flower bun.

[0027] The grate plate 2 is disc-shaped, with ventilation holes 21 and ventilation square holes 22 evenly distributed on it. Figure 2 As shown, the water vapor generated in the bottom box 4 can rise into the box cover through the vent hole 21 to heat the steamed bun. The vent hole 22 is mainly used to position and install the bag rack 3. A positioning notch 23 is processed on the edge of the grating plate, which cooperates with the positioning protrusion 43 on the inner surface of the upper opening of the bottom box to achieve the positioning installation of the grating plate, lay the foundation for the positioning of the sharp protrusion 41 and the puncture hole 33, and prevent the grating plate from rotating.

[0028] Package rack 3 as attached Figure 4 and attached Figure 5 As shown, it includes a pressure rod 31, a baffle 32, a puncture hole 33, and a bag groove 34. The cross section of the pressure rod 31 is a square that matches the ventilation square hole 22. It passes through the ventilation square hole 22 on the grating plate. A baffle 32 is fixed on the outer surface of the pressure rod. The baffle 32 contacts the grating plate to prevent the bag frame from moving down. At the bottom end of the pressure rod 31, a bag groove 34 is fixed, and the bag groove 34 is used to place the heating bag 5. On the bag groove 34, a puncture hole 33 is designed, and the puncture hole 33 corresponds to the sharp protrusion 41 on the bottom box. It should be noted that in order to ensure the installation of the bag frame 3, the baffle 32 should be spot welded on the pressure rod 31 after the pressure rod 31 is sleeved on the ventilation square hole. The bag frame is usually made of plastic, and spot plastic welding is sufficient, which is convenient and quick.

[0029] The bottom box 4 is located at the bottom of the packaging box, and the inner surface of the upper opening is designed with a boss 42, which can be a whole ring or a local protrusion evenly distributed on the upper opening. The function of the boss 42 is to fix and support the grating plate 2. A positioning protrusion 43 is designed on the inner surface of the upper opening, and the positioning protrusion 43 cooperates with the positioning notch 23 on the grating plate to realize the positioning of the grating plate. At the inner bottom of the bottom box 4, a sharp protrusion 41 is designed, and the position of the sharp protrusion 41 corresponds to the position of the puncture hole 33 on the bag rack. To ensure that the bag rack is installed after the vent hole, the puncture hole corresponds to the position of the sharp protrusion, the pressure rod and the ventilation square hole should be rectangular, which is convenient for positioning and installing and preventing the rotation of the pressure rod. At the position of the ventilation square hole 22, the thickness of the grating plate should be increased. Under the same gap condition, the larger the depth of the ventilation square hole, the smaller the offset angle of the pressure rod, which is more conducive to the cooperation of the sharp protrusion and the puncture hole.

[0030] The heating pack 5 is purchased from outside, and is filled with self-heating material mainly composed of lime that releases heat when reacting with water. The size of the heating pack 5 corresponds to the size of the pack slot 34, and can be inserted and fixed in the pack slot 34 to maintain its position unchanged during transportation.

[0031] When the present embodiment is used, the flower bun is placed in a packaging box, tied up, and delivered to the customer by express delivery. The lid is opened, and water is added through the vent hole until the water surface is at the tip of the sharp convex. When the ceremony is completed and ready to be eaten, the lid is opened, the pressure rod is pressed, and the baffle is peeled off from the pressure rod. The heating pack moves down with the package frame. After the sharp convex passes through the puncture hole, the wrapping paper of the heating pack is destroyed. The water contacts the self-heating material, an exothermic reaction occurs, and water vapor is generated to heat the flower bun. It should be noted that although there is a gap when the positioning protrusion and the positioning notch are positioned on the grating plate, and there is also a gap when the ventilated square hole is positioned on the pressure rod, it is very likely that the center of the puncture hole is eccentric to the center of the sharp convex. However, as long as the tip of the sharp convex is inserted into the puncture hole, the guiding effect of its tip can make the puncture hole match the sharp convex. To take a step back, even if the sharp convex is damaged due to the eccentric force, the sharp convex has destroyed the heating pack at this time, and the self-heating material has contacted with water to react exothermically, which does not affect the heating effect of the flower bun.

[0032] Since the amount of heat released by each heating pack is determined, the amount of steam required to heat the steamed buns varies with climate change. Therefore, six pack rack positions are provided in this embodiment. Figure 3 As shown, the number of heating packs can be adjusted according to seasonal changes, and two heating packs are placed in the figure. Example 2

[0033] This embodiment is an improvement on the basis of embodiment 1. Figure 6 As shown. In Example 1, it is necessary to open the lid and add water to the bottom box, which is detrimental to the customer experience. In this embodiment, water is directly added to the bottom box 4, which is sealed with a sealing paper 44. The sealing paper 44 is bonded and fixed to the inner wall of the bottom box, thereby sealing the water. The height of the water is higher than the sharp protrusion to avoid the sharp protrusion damaging the sealing paper, and it will not overflow during transportation. Before eating, the customer only needs to open the lid once and press the pressure rod to destroy the sealing paper 44. The sharp protrusion passes through the puncture hole, and the self-heating material contacts the water, so that the self-heating of the flower bun can be achieved. There is no need to worry about the amount of water added, which enhances the customer experience.

[0034] Another improvement of the present embodiment is to add a foot ring 45 to the bottom surface of the bottom box, the size of which is consistent with the size of the lower step of the box cover, and can be buckled with the upper step of the bottom box. In this way, when the bottom box is stored, it can be stacked and positioned to save storage space.

[0035] It should be noted that the utility model is drawn and described in a circle, but is not limited to a circle. Due to the various shapes of the flower bun, it can also be designed into other shapes such as an ellipse or a square, and the hemispherical shape of the upper part of the box cover can be changed accordingly. In addition, the hemispherical shape of the upper part of the box cover can also be replaced with other shapes, such as a semi-ellipsoidal shape, an arc shape, and other inclined shapes, as long as the top inner surface of the box cover is an inclined surface, the water droplets will not drip, but can flow down along the inner wall of the box cover.

[0036] The utility model uses the self-heating material in the heating bag to react with water to release heat and generate steam to heat the steamed bun. It does not require electricity or other heat sources, is not restricted by the environment and resources, and is convenient and fast. The heating operation only requires pressing the pressure rod and closing the lid, which is simple and convenient, and provides a good customer experience. Steam droplets flow down along the inner wall of the lid and will not drip on the steamed bun, thereby not destroying the artistic beauty of the steamed bun. The air vents are set on the buckling surface of the lower mouth of the lid, and the steamed bun is evenly heated without dust pollution. The lid is made of transparent material, the steamed bun is visible, and the sense of ceremony is strong.
