[0032] First embodiment

[0033] Please refer to Figure 1 and Figure 2The present embodiment provides an easily-openable packaging box 100, which includes a box body 110 and a tape layer 120. The box body 110 includes a first side wall 111 and a second side wall 112 opposite to each other. The second side wall 112 is provided with an easy-tear area 130 formed by a dotted area 131 or an easy-tear hole 132. One end of the tape layer 120 is connected to the first side wall 111, and the other end extends to the top of the box body 110 and seals the opening and then continues to extend to the second side wall 112. The tape layer 120 covers part of the easy-tear area 130.

[0034] See also Figure 3 The box body 110 is a conventional rectangular parallelepiped box body, which is composed of four side walls, a top wall 115 and a bottom wall 116, and is a cardboard material for forming an easily detachable packaging box. The four side walls include an opposite first side wall 111 and a second side wall 112, an opposite third side wall 113 and a fourth side wall 114, the top wall 115 is formed by at least two opposite first opening and closing plates 1151, and the bottom wall 116 is formed by at least two opposite second opening and closing plates 1161. The first opening and closing plates 1151 are connected to the tops of two opposite side walls among the four side walls (specifically, Figure 3 In the embodiment, the first opening and closing plate 1151 is connected to the top of the third side wall 113 and the fourth side wall 114), and the second opening and closing plate 1161 is connected to the bottom of two opposite side walls among the four side walls (specifically Figure 3 In the embodiment, the second opening and closing plate 1161 is connected to the bottom of the third side wall 113 and the fourth side wall 114), and one of the four side walls that is not connected to the first opening and closing plate 1151 (such as Figure 3 The first side wall 111 in the box is provided with an easy-tear area 130 formed by a dotted area 131 or an easy-tear hole 132. The easy-tear area 130 is provided in the direction in which the gap between the two opposite first opening and closing plates 1151 is extended along the side wall when the gap is closed. By providing an easy-tear area 130 on the basis of the conventional box body 110, rapid unpacking can be achieved during subsequent unpacking. At the same time, the provision of the cardboard material used to form the easy-to-disassemble packaging box 100 can facilitate the factory processing of the box body 110. At the same time, when not assembled, the four side walls, the top wall 115 and the bottom wall 116 can be folded to form a plate shape, which is conducive to reducing the volume, facilitating storage and transportation, and can also achieve factory batch processing. When using it, the operator can directly assemble it, and then use tape to seal the opening to form a tape layer 120. During the sealing process, the tape layer 120 covers part of the easy-tear area 130, and then when unpacking, rapid unpacking can be achieved.

[0035] The "dotted line area 131" refers to an easy-tear area 130 composed of dots and lines formed by punching with a conventional punching mechanism (such as a laser). In the dotted line area 131, the operator can apply external force and tear it easily along the dotted lines. During the tearing process, the opening is smooth. The dotted line area 131 can be a solid line mark, a dotted line mark, or a mark with different line shapes, with a wide range of options and many types.

[0036] The “easy-tear hole 132” is a hole structure, and the operator can insert a finger into the easy-tear hole 132 to tear the tape layer 120 in the easy-tear hole 132, so that the tape layer 120 is torn along its sticking position to achieve quick unpacking.

[0037] In this embodiment, the tape layer 120 covers a portion of the easy-to-tear area 130, so that the portion of the tape layer 120 that does not cover the easy-to-tear area 130 can be quickly torn off, and then the tape layer 120 will be torn off together with the other positions along the easy-to-tear area 130. At this time, the packaging box can be opened along the tape layer 120, and the operation is simple.

[0038] Specifically, the covered area is that 1 / 3-1 / 2 of the tape layer 120 along its width direction partially covers more than 1 / 2 of the dotted area 131. The tape layer 120 covers a larger area, which can effectively prevent the problem of the tape layer 120 being difficult to tear open due to insufficient force during unpacking.

[0039] One or more or all of the dotted line area 131 are dotted line structures, wherein the dotted line area 131 outside the tape layer 120 is a dotted line structure, and the dotted line structure outside the tape layer 120 is convenient to tear, so that the tape layer 120 is torn apart at the same time as the dotted line area 131 is torn apart. Specifically in this embodiment, the dotted line structure is provided at the edge of the dotted line area 131 of this embodiment, which makes the operation simpler and also makes it easier to cover the tape layer 120.

[0040] In this embodiment, there can be multiple patterns of the easy-tear area 130, which can be selected according to actual conditions. For example, the pattern of the easy-tear area 130 is polygonal, circular, elliptical, semicircular or irregular. Among them, polygons include but are not limited to triangles, rectangles, squares, rhombuses, pentagons or hexagons. Irregular shapes include but are not limited to crescents, stars or zigzags. Specifically in this embodiment, the pattern of the easy-tear area 130 is a square dotted area 131, and preferably the tape layer 120 covers at least one right-angle area of ​​the easy-tear area 130, so that when unpacking, the easy-tear area 130 is easy to tear open, and at the same time, the contact area between the easy-tear area 130 and the tape layer 120 is large, which ensures the bonding strength between the easy-tear area 130 and the tape layer 120, and it is easy to tear open the tape layer 120 together, ensuring the efficiency of unpacking.

[0041] In this embodiment, the area of ​​the easy-tear region 130 is 2-6 cm 2 The easy-tear region 130 is relatively small in area, and will not affect the overall structure and compression resistance of the box body 110, nor will it affect the adhesive properties of the tape layer 120, but can provide a small easy-tear opening, so that the person opening the box can tear open the entire easy-to-open packaging box 100 from the opening formed by the easy-tear region 130. Preferably, the easy-tear region 130 is located on the side wall of the box body 110, and more preferably close to the end of the tape layer 120, so that the tape layer 120 can be easily torn open.

[0042] In addition, the dotted line structure is composed of a plurality of dotted lines arranged at intervals, the length of each dotted line is 2-6 mm, and the interval between any two dotted lines is 2-4 mm. Preferably, the length of the dotted line is 5 mm, and the interval is 2 mm. In this embodiment, the range of the dotted line area 131 is small, and it is only used to tear off the tape, and will not affect the strength and easy disassembly. Therefore, the dotted line area 131 provided in this embodiment can ensure the strength of the box body 110 while also achieving easy disassembly.

[0043] The working principle of the easy-to-open packaging box 100 is: by using the easy-to-open area 130 formed by the dotted area 131 or the easy-to-open hole 132 set on the box body 110 and the design that the tape layer 120 covers part of the easy-to-open area 130, the uncovered easy-to-open area 130 can be easily torn open, and then the tape layer 120 will be torn open along the other positions of the easy-to-open area 130, so that the packaging box can be opened along the tape layer 120, and the operation is simple. In addition, the dotted area 131 in this embodiment is relatively small in area, which will not affect the overall structure and pressure resistance of the box body 110, and it is also easy to tear the tape layer 120, so that it can be quickly disassembled without tools during the unpacking process.

[0044] Therefore, the easily dismantled packaging box 100 provided by the utility model has a dotted area 131 set at a position of the box body 110 close to the tape layer 120, and the tape layer 120 covers the part of the dotted area 131. When unpacking the box, the part of the tape layer 120 that does not cover the dotted area 131 can be quickly torn off, and then the tape layer 120 will be torn off together with the other positions along the dotted area 131. At this time, the packaging box can be opened along the tape layer 120, and the operation is simple. The easily dismantled packaging box 100 provided by the utility model can achieve quick and convenient opening on the basis of meeting the requirements of pressure resistance and non-deformation.

[0045] Second embodiment

[0046] During the research, the utility model found that the packaging box has a storage function in addition to the function of transportation turnover, especially in the cold drink industry, the products are packed in cartons and then stored in cold storage. Due to the high production speed of the production line, the freezing effect in the cold storage is particularly important for cold drink products, especially some large barrels of ice cream and soft ice cream slurry. Large barrels of ice cream have a sealed thick paper barrel with slow cold conduction; soft ice cream slurry is poured at room temperature, put into cartons and then enter the cold storage for freezing. How to improve the freezing efficiency of the cold storage is also a problem that the utility model needs to solve.

[0047] Therefore, based on the first embodiment, this embodiment further provides through holes for cold transfer on both sides of the box body 110 .

[0048] Specifically, see Figure 4 The box body 110 includes a first side wall 111 and a second side wall 112 opposite to each other. A first vent hole 117 is provided on the first side wall 111, and a second vent hole 118 is provided on the second side wall 112. The first vent hole 117 is arranged at 1 / 3-1 / 5 of the height direction of the first side wall 111 from top to bottom, and the second vent hole 118 is arranged at 2 / 3-4 / 5 of the height direction of the second side wall 112 from top to bottom. In this embodiment, by arranging the first vent hole 117 and the second vent hole 118 one above the other, a convection state can be formed, thereby facilitating the conduction of cold air in both the upper and lower parts of the box body 110, achieving better conduction effect, better freezing effect, and helping to improve freezing efficiency.

[0049] The diameter of the first vent hole 117 and the second vent hole 118 is about 2-5 cm. In this embodiment, the size of the first vent hole 117 and the second vent hole 118 is small, which will not affect the overall structure and pressure resistance of the box body 110, and will not affect the bonding performance of the tape layer 120.

[0050] like Figure 2 As shown, the first vent hole 117 in this embodiment can be used to replace the easy-tear hole 132, so that it is easy to open the tape while ensuring cold conduction. Figure 5 As shown, the first vent hole 117 and the dotted area 131 may also be provided separately.

[0051] The easily dismantled packaging box 100 provided in this embodiment can facilitate the entry of cold air into the box body 110 during the freezing process by setting the first ventilation hole 117 and the second ventilation hole 118. The cold air is fully conducted inside the box body 110, which is beneficial to improving the freezing efficiency. Therefore, this embodiment can achieve fast unpacking and fast cooling at the same time.

[0052] In summary, the easy-to-open packaging box 100 provided by the utility model is provided with an easy-to-open area 130 formed by a dotted area 131 or an easy-to-open hole 132 at a position of the box body 110 close to the tape layer 120, and the tape layer 120 covers the part of the easy-to-open area 130. When unpacking, the part of the tape layer 120 that does not cover the easy-to-open area 130 can be quickly torn open, and then the tape layer 120 will be torn open along other positions of the easy-to-open area 130. At this time, the packaging box can be opened along the tape layer 120, and the operation is simple. The easy-to-open packaging box 100 provided by the utility model can be opened quickly and conveniently on the basis of meeting the requirements of pressure resistance and non-deformation. The first vent hole 117 and the second vent hole 118 in the utility model can meet the requirements of good cold air conduction and improve the freezing efficiency.

[0053] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
