Description

Technical Field

[0001] This application belongs to the field of medical device technology, and in particular relates to a packaging box. Background Technology

[0002] The combination of medical blister packs and heat-sealing caps to form a packaging box is a common form of medical device packaging. This ensures the medical device remains in a sterile environment during storage and transportation, improves physical protection, and facilitates clean and aseptic removal by medical personnel. Many medical devices (such as floating catheters) require pre-treatment (e.g., in vitro calibration) before use. This typically involves tearing open a portion of the heat-sealing cap to expose the corresponding part of the medical device for pre-treatment. However, currently, the heat-sealing caps on these packaging boxes are difficult to tear precisely. Utility Model Content

[0003] This application provides a packaging box that can be opened with relatively precise accuracy.

[0004] In a first aspect, embodiments of this application provide a packaging box having two or more functional areas and at least one stable area, the stable area being located between two adjacent functional areas. The packaging box includes a box body and a box lid. The box body includes a box main body and an edge sealing structure, the edge sealing structure being arranged circumferentially around the box main body. The box lid is closed onto the box main body and heat-sealed to the edge sealing structure. The box lid can be torn open along a first direction to expose the functional components inside the box main body. The first direction is the direction from one of the two adjacent functional areas toward the other. The connection strength between the box lid and the edge sealing structure in the stable area is greater than the connection strength between the box lid and the edge sealing structure in the functional areas.

[0005] In some embodiments, the edge sealing structure includes a first edge sealing portion located in the functional area and a second edge sealing portion located in the stable area. In a second direction, the cumulative dimension of the second edge sealing portion is greater than the cumulative dimension of the first edge sealing portion, and the second direction is perpendicular to the first direction.

[0006] In some embodiments, the first sealing portion includes a first sub-portion and a second sub-portion located at different edges of the box body, and the second sealing portion includes a third sub-portion and a fourth sub-portion located at different edges of the box body, wherein the first sub-portion and the third sub-portion are located at the same edge, and the second sub-portion and the fourth sub-portion are located at the same edge; in a second direction, the size of the third sub-portion is larger than the size of the first sub-portion; and / or, in a second direction, the size of the fourth sub-portion is larger than the size of the second sub-portion.

[0007] In some embodiments, the two or more functional areas include a first functional area and a second functional area. The first functional area is located on the side of the stable area near the tear-off end, and the second functional area is located on the side of the stable area away from the tear-off end. The first sealing portion located in the first functional area includes a main body segment and a transition segment located on the same side edge of the box body. The transition segment connects the main body segment and the second sealing portion. The transition segment and the second sealing portion together protrude into the box body to form a protrusion and define a groove corresponding to the protrusion on the outer side.

[0008] In some embodiments, at least one of the transition section and the second sealing portion extends in an arc shape; or, the transition section extends in an arc shape, and the angle α between the tangent of the transition section and the main body section satisfies: 90°≤α<180°.

[0009] In some embodiments, along the extension direction perpendicular to the main body segment, the ratio Z1 of the size of the transition segment to the size of the main body segment satisfies: 2≤Z1≤4; and / or, in the second direction, the ratio Z2 of the size of the second sealing portion to the size of the main body segment satisfies: 2≤Z2≤4.

[0010] In some embodiments, along the extension direction perpendicular to the main body segment, the dimension H2 of the main body segment satisfies: 8≤H2≤12mm; and / or, at least one corner portion is formed in the edge sealing structure, the width of the corner portion being greater than or equal to 12mm and less than or equal to 15mm.

[0011] In some embodiments, the box body includes a first edge, a second edge, a third edge, and a fourth edge that are joined end to end, and there are two second sealing portions; the tear-off end is disposed near the junction of the first edge and the fourth edge, and the two second sealing portions are respectively located at the first edge and the fourth edge; or, the tear-off end is disposed near the junction of the first edge and the fourth edge, and the two second sealing portions are respectively located at the second edge and the third edge; or, the tear-off end is located at the fourth edge, and the two second sealing portions are respectively located at the first edge and the third edge.

[0012] In some embodiments, the edge sealing structure includes an edge sealing portion and a recessed portion, the recessed portion being located on the side of the edge sealing portion away from the functional area, and the boundary line between the edge sealing portion and the recessed portion intersecting with a first direction; the recessed portion is recessed relative to the edge sealing portion toward the side away from the box lid, and the box lid is heat-sealed to the edge sealing portion.

[0013] In some embodiments, a pre-fold line is formed on the side of the lid facing away from the box body. The pre-fold line extends perpendicularly to the first direction and is located at the junction of the first functional area and the corresponding stable area.

[0014] This application provides a packaging box having two or more functional areas and at least one stable area. The stable area is located between two adjacent functional areas. The packaging box includes a box body and a box lid. The box body includes a main body and an edge sealing structure. The edge sealing structure is arranged around the circumference of the main body. The box lid closes onto the main body, thereby forming a receiving cavity for accommodating functional components. The box lid and the edge sealing structure are heat-sealed together. An operator can first tear off part of the box lid in a first direction to expose some functional components located in the first functional area inside the box body, and perform positioning and calibration through these functional components. After positioning and calibration, the remaining part of the box lid can be torn off in the first direction to expose the remaining functional components for use. During this process, since the connection strength between the lid and the sealing structure in the stable zone is greater than that in the functional zone, when the lid is torn to the boundary between the first functional zone and the corresponding stable zone, the operator can obtain force feedback of different intensities, producing a sense of jerkiness, prompting the operator to stop the action, thereby reducing the risk of the lid being accidentally torn in other functional zones, improving the accuracy of the lid tearing and avoiding calibration deviation.

[0024] The features and exemplary embodiments of various aspects of this application will now be described in detail. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain this application and are not configured to limit this application. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples of this application.

[0025] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0026] Many medical devices (such as floating catheters) require pre-calibration in vitro before use. Calibration typically involves tearing open a portion of the packaging lid to expose the corresponding part of the medical device, which is then used for calibration. For ease of understanding, the following explanation will use an application scenario suitable for floating catheters as an example.

[0027] Currently, there are various ways to tear open the packaging boxes used for packaging such medical devices. For example, a cutting line can be pre-set on the lid so that part of the lid can be torn open along the cutting line. However, the lids of the aforementioned packaging boxes are difficult to tear precisely. For example, operators may use excessive force and accidentally tear off the remaining part of the lid, which could lead to contamination of the remaining medical devices during calibration and may cause calibration deviations, affecting the safety of the medical devices.

[0028] In view of this, embodiments of this application provide a packaging box that can solve at least some of the above-mentioned technical problems. For example... Figure 1 and Figure 2 As shown, the packaging box has two or more functional areas K1 and at least one stable area K2. The stable area K2 is located between two adjacent functional areas K1. The packaging box includes a box body 100 and a box lid 200. The box body 100 includes a box main body 110 and an edge sealing structure 120. The edge sealing structure 120 is arranged around the circumference of the box main body 110. The box lid 200 is closed to the box main body 110 and heat-sealed to the edge sealing structure 120. The box lid 200 can be torn open along a first direction X to expose the functional components inside the box main body 110. The first direction X is the direction from one of the two adjacent functional areas K1 to the other. The connection strength between the box lid 200 and the edge sealing structure 120 in the stable area K2 is greater than the connection strength between the box lid 200 and the edge sealing structure 120 in the functional area K1.

[0029] It should be noted that the packaging box provided in this application embodiment can be used to package medical devices, that is, the functional component is a medical device. Alternatively, the packaging box provided in this application embodiment can also be used to package other structures, and this embodiment does not limit this. The first direction X in this application embodiment is the length direction or width direction of the box body 110. Alternatively, when the box body 100 is a square box, the first direction X can be a direction approximately parallel to a diagonal of the box body 110.

[0030] Specifically, the packaging box has functional areas K1 and stable areas K2, which can be approximately distributed along a first direction X. Alternatively, some functional areas K1 and stable areas K2 can be approximately distributed along the first direction X, while others can be distributed along other directions. The number of functional areas K1 is greater than or equal to two. Stable areas K2 are located between two adjacent functional areas K1. There can be one or more stable areas K2. When there are multiple stable areas K2, multiple stable areas K2 can be located simultaneously between two adjacent functional areas K1, or multiple stable areas K2 can be set one-to-one between different adjacent functional areas K1.

[0031] The packaging box includes a box body 100 and a box lid 200. The box body 100 includes a main body 110 and an edge sealing structure 120. The main body 110 has a storage slot for placing functional components. It is understood that a portion of the storage slot can be located in each functional area K1, and another portion can be located in a stable area K2. When a functional component is placed in the storage slot, a portion of the component can be located in each functional area K1, while another portion is located in the stable area K2. The functional components located in each functional area K1 can be connected into a whole through the functional components located in the stable area K2. The main body 110 can be square, circular, or other shapes; this embodiment does not limit this. The edge sealing structure 120 is distributed around the circumferential edge of the main body 110, and its shape can be adapted to the outer contour shape of the main body 110.

[0032] The lid 200 is used to cover the box body 110, and it can enclose the box body 110 to form a receiving cavity in the storage slot. Therefore, the lid 200 can protect the functional components located in the storage slot of the box body 110 and form a sterile barrier system. The lid 200 can be heat-sealed to the sealing structure 120 along the circumference of the box body 110. In some implementations, the connection process may involve placing the glued lid 200 and the box body 100 in a heat-sealing packaging machine for heating and pressurization. The glue layer melts, causing the lid 200 and the sealing structure 120 to adhere together, thereby achieving the function of sealing.

[0033] The packaging box has a tear-off end K3, which can be located at any position around the circumference of the packaging box. For example, when the packaging box is square, the tear-off end K3 can be located at the junction of two adjacent edges of the packaging box, or it can be located at any edge of the packaging box. It is understood that since the lid 200 and the sealing structure 120 are connected by a heat-sealing process, when an operator applies force to the lid 200 from the tear-off end K3, the lid 200 can be torn off along the first direction X from the tear-off end K3. During the tearing process, the lid 200 located in the first functional area K1 separates from the sealing structure 120 first, exposing some functional components located in the first functional area K1. At this time, calibration can be performed through these functional components located in the first functional area K1. After calibration, force is applied to the lid 200, causing the lid 200 located in the stable zone K2 and other functional zones K1 to separate from the sealing structure 120 in sequence. Some functional components located in the stable zone K2 and some functional components located in other functional zones K1 are exposed in sequence, realizing the step-by-step opening of the packaging box.

[0034] Understandably, because the connection strength between the lid 200 and the sealing structure 120 in the stable zone K2 is greater than that in the functional zone K1, the operator needs to apply forces of varying strengths to separate the lid 200 from the sealing structure 120 in both the stable zone K2 and the functional zone K1. In other words, when the lid 200 is torn to the boundary between the first functional zone K1 and the first stable zone K2, the operator receives force feedback of varying strengths, producing a jerky sensation that prompts them to stop and calibrate the functional components. This reduces the risk of premature tearing of the lid 200 in other functional zones K1, improves the accuracy of lid tearing, and avoids calibration deviations.

[0035] Furthermore, in related technologies, tearing open a portion of the lid 200 along the cut line may cause the lid 200 to delaminate and shed lint during the tearing process, further contaminating the functional components inside the box body 110. However, the packaging box provided in this application eliminates the need to tear the lid 200 along the cut line, reducing the risk of delamination and lint shedding during the tearing process, further minimizing the possibility of contamination of functional components, and improving the safety of medical device use.

[0036] It should be noted that, in the embodiments of this application, the first functional area K1 refers to the functional area K1 closest to the tear-off end K3 in the first direction X, and the first stable area K2 refers to the stable area K2 closest to the tear-off end K3 in the first direction X.

[0037] It is understandable that the connection strength between the lid 200 and the edge sealing structure 120 can be affected by various factors. For example, the connection strength between the lid 200 and the edge sealing structure 120 can be affected by their connection area; the larger the connection area, the higher the connection strength. Furthermore, the connection strength between the lid 200 and the edge sealing structure 120 is also affected by factors such as time and temperature during the heat sealing process. However, when the edge sealing width is the same, the overall connection strength of the edge sealing is basically consistent. Therefore, this embodiment of the application achieves zoned adjustment of the connection strength between the lid 200 and the edge sealing structure 120 in the stable zone K2 and the functional zone K1 by adjusting the connection area between the lid 200 and the edge sealing structure 120.

[0038] Please continue reading. Figure 2 In some embodiments, the edge sealing structure 120 includes a first edge sealing portion 121 located in the functional area K1 and a second edge sealing portion 122 located in the stable area K2. In the second direction Y, the cumulative size of the second edge sealing portion 122 is greater than the cumulative size of the first edge sealing portion 121. The second direction Y is perpendicular to the first direction X.

[0039] Specifically, the first sealing portion 121 may include a first sub-portion 1211 and a second sub-portion 1212 located on different edges of the box body 110, and the second sealing portion 122 may include a third sub-portion 1221 and a fourth sub-portion 1222 located on different edges of the box body 110. The first sub-portion 1211 and the third sub-portion 1221 are located on the same edge, and the second sub-portion 1212 and the fourth sub-portion 1222 are located on the same edge. The cumulative dimension of the first sealing portion 121 may be the sum of the dimensions of the first sub-portion 1211 and the second sub-portion 1212 in the second direction Y, and the cumulative dimension of the second sealing portion 122 may be the sum of the dimensions of the third sub-portion 1221 and the fourth sub-portion 1222 in the second direction Y.

[0040] In some embodiments, the size of the third sub-part 1221 may be larger than the size of the first sub-part 1211, and the size of the fourth sub-part 1222 may be equal to the size of the second sub-part 1212.

[0041] In some other embodiments, the size of the fourth sub-part 1222 may be larger than the size of the second sub-part 1212, and the size of the third sub-part 1221 may be equal to the size of the first sub-part 1211.

[0042] In some other embodiments, the size of the third sub-part 1221 may be larger than the size of the first sub-part 1211, and the size of the fourth sub-part 1222 may be larger than the size of the second sub-part 1212.

[0043] In these embodiments, by setting the cumulative size of the second sealing portion 122 to be greater than the cumulative size of the first sealing portion 121, the connection area between the second sealing portion 122 and the lid 200 per unit length in the first direction X can be greater than the connection area between the first sealing portion 121 and the lid 200 per unit length. Under the condition that the heat sealing temperature, time and other variables of the first sealing portion 121 and the second sealing portion 122 are constant, the connection strength between the second sealing portion 122 and the lid 200 can be greater than the connection strength between the first sealing portion 121 and the lid 200.

[0044] It should be noted that the second direction Y in this embodiment can be a direction perpendicular to the first direction X. For example, when the box body 110 is a square box and the first direction X is approximately parallel to one diagonal of the box body 110, the second direction Y can be approximately parallel to the other diagonal of the box body 110.

[0045] Please see Figure 3In some embodiments, the two or more functional areas K1 include a first functional area K11 and a second functional area K12. The first functional area K11 is located on the side of the stable area K2 near the tear-off end K3, and the second functional area K12 is located on the side of the stable area K2 away from the tear-off end K3. The first sealing portion 121 located in the first functional area K11 includes a main body segment 1213 and a transition segment 1214 located on the same side edge of the box body 110. The transition segment 1214 connects the main body segment 1213 and the second sealing portion 122. The transition segment 1214 and the second sealing portion 122 together protrude into the box body 110 to form a protrusion, and define a groove K4 corresponding to the protrusion on the outer side. Wherein, the transition segment 1214 and the second sealing portion 122 together protrude into the box body 110 to form a protrusion, which can be understood as the entire combination of the transition segment 1214 and the second sealing portion 122 protruding into the box body 110 to form a protrusion, and similarly, the common protrusion away from the box body 110 as mentioned below. The groove K4 can provide certain guidance to the operator during the tearing process of the cover 200, so as to further reduce the risk of the cover 200 located in other functional areas K1 being accidentally torn during positioning calibration, and reduce the possibility of deviation of functional components during calibration.

[0046] In some other embodiments of this application, the transition section 1214 and the second sealing edge 122 are recessed into the box body 110 to form a groove K4, and a protrusion corresponding to the groove K4 is defined on the outside.

[0047] The first functional area K11 and the second functional area K12 can be any two adjacent functional areas K1 among the multiple functional areas K1 of the packaging box. There is a stable area K2 between the first functional area K11 and the second functional area K12. The first functional area K11 is located on the side of the stable area K2 along the first direction X close to the tear-off end K3, and the second functional area K12 is located on the side of the stable area K2 along the first direction X away from the tear-off end K3. During the process of tearing the box cover 200 along the first direction X from the tear-off end K3, the box cover 200 of the first functional area K11 is torn off before the box cover 200 of the second functional area K12.

[0048] Both the first functional area K11 and the second functional area K12 have a first sealing portion 121. The first sealing portion 121 in the first functional area K11 includes a main body segment 1213 and a transition segment 1214. The main body segment 1213 and the transition segment 1214 are located on the same side edge of the box body 110. The main body segment 1213 can extend approximately along the edge of the box body 110. The transition segment 1214 is located between the main body segment 1213 and the second sealing portion 122 in the corresponding stable area K2. That is, the end of the transition segment 1214 near the tear end K3 is connected to the end of the main body segment 1213 away from the tear end K3, and the end of the transition segment 1214 away from the tear end K3 is connected to the corresponding second sealing portion 122.

[0049] It should be noted that in the embodiments of this application, the two or more functional areas K1 include the first functional area K11 and the second functional area K12, and are not limited to the packaging box having only the first functional area K11 and the second functional area K12. The packaging box provided in the embodiments of this application may also include other functional areas K1. Furthermore, the first functional area K11 and the second functional area K12 can be two relative concepts, and do not absolutely refer to a certain functional area K1. For example, in three functional areas K1 arranged sequentially and adjacently along the first direction X, the second functional area K1 is the second functional area K12 relative to the first functional area K1, but it can be the first functional area K11 relative to the third functional area K1. In this case, the first sealing portion 121 in the second functional area K1 may also include the main body section 1213 and the transition section 1214. One end of the transition section 1214 is connected to the corresponding main body section 1213, and the other end is connected to the second sealing portion 122 in the stable area K2 between the second functional area K1 and the third functional area K1.

[0050] The inner side of the transition section 1214 and the inner side of the second sealing edge 122 both protrude into the box body 110, and the outer side of the transition section 1214 and the outer side of the second sealing edge 122 both indent into the box body 110. At this time, the transition section 1214 and the second sealing edge 122 are equivalent to bending and extending into the box body 110 together. The angle between the extension direction of the second sealing edge 122 and the second direction Y can be smaller than the angle between the extension direction of the corresponding main body section 1213 and the second direction Y. Preferably, the second sealing edge 122 can extend approximately along the second direction Y, so that the size of the second sealing edge 122 along the second direction Y is larger than the size of the first sealing edge 121 along the first direction X.

[0051] Furthermore, the inner side of the transition section 1214 and the inner side of the second sealing edge 122 protrude into the box body 110. When the functional component is located inside the box body 110, the inner side of the transition section 1214 and the inner side of the second sealing edge 122 can also limit the functional component to a certain extent, thereby improving the stability of the functional component.

[0052] It should be noted that the extension direction in this embodiment can be the length direction of the corresponding component, and it can be an approximate extension direction, rather than an absolutely precise extension direction. In the second direction Y, the size of the transition segment 1214 can be the same as the size of the main body segment 1213, or it can be slightly larger than the size of the main body segment 1213, as long as there is a certain size difference between the transition segment 1214 and the second sealing edge 122. The inner and outer sides mentioned in this embodiment can be the opposite sides of the corresponding component, where the inner side can refer to the side of the corresponding component closer to the storage slot of the box body 110, and the outer side can refer to the side of the corresponding component away from the storage slot of the box body 110, that is, the side of the corresponding component closer to the external environment of the packaging box.

[0053] In some embodiments, at least one of the transition section 1214 and the second sealing edge portion 122 extends in an arc shape, which is beneficial for the forming and manufacturing of the corresponding heat sealing mold, and can make the shape of the transition section 1214 and / or the second sealing edge portion 122 more compatible with the shape of the functional component, thereby improving the space utilization rate inside the box body 110 for accommodating the functional component.

[0054] It should be noted that when the shape of the transition section 1214 and the second sealing edge 122 is adapted to the shape of the functional component, the inner side of the transition section 1214 and the inner side of the second sealing edge 122 can serve as the sidewall of the storage slot, respectively fitting into the functional component, thereby improving the space utilization rate of the storage slot.

[0055] Please continue reading. Figure 3 In other embodiments, the transition segment 1214 extends in an arc shape, and the angle α between the tangent of the transition segment 1214 and the main body segment 1213 satisfies: 90°≤α<180°.

[0056] Specifically, when the transition segment 1214 extends in an arc shape, the tangent of the transition segment 1214 can refer to the tangent on the inner side of the transition segment 1214 or the tangent on the outer side of the transition segment 1214. The angle α between the tangent of the transition segment 1214 and the main body segment 1213 can be the angle between the tangent on the inner side of the transition segment 1214 and the inner extension line of the main body segment 1213, or the angle between the tangent on the outer side of the transition segment 1214 and the inner extension line of the main body segment 1213.

[0057] In these embodiments, by setting the angle between the tangent of the transition segment 1214 and the main body segment 1213 to be greater than or equal to 90° and less than 180°, compared to setting the angle to be less than 90°, the transition segment 1214 can tend to extend away from the main body segment 1213, instead of bending and extending to the side of the main body segment 1213 along the second direction Y. This reduces the difficulty of tearing the sealing structure and the lid 200 in the first functional area K1 along the first direction X, making the lid 200 easier to tear.

Figure 3 In some embodiments, along the extension direction perpendicular to the main body segment 1213, the ratio Z1 of the dimension H1 of the transition segment 1214 to the dimension H2 of the main body segment 1213 satisfies: 2≤Z1≤4. For example, the ratio of the dimension H1 of the transition segment 1214 to the dimension H2 of the main body segment 1213 can be 2, 2.5, 3, 3.5, 4, etc., so as to reasonably set the length of the transition segment 1214 bending and extending into the box body 110 relative to the main body segment 1213. This does not affect the utilization rate of the internal space of the packaging box, while allowing the dimension of the second sealing edge 122 in the second direction Y to a certain extent. The section, namely adjusting the connection strength between the second sealing part 122 and the box cover 200, can be derived from the ratio of H1 to H2 and the angle α between the tangent of the transition section 1214 and the main body section 1213. It can be deduced that in the second direction Y, the ratio Z2 of the dimension H3 of the second sealing part 122 to the dimension H4 of the main body section 1213 satisfies: 2≤Z2≤4. For example, the ratio of the dimension H3 of the second sealing part 122 to the dimension H4 of the main body section 1213 can be 2, 2.5, 3, 3.5, 4, etc., so as to further optimize the dimension design of the second sealing part 122 in the second direction Y. On the one hand, it creates a large gradient between the connection strength between the first sealing edge 121 and the lid 200 and the connection strength between the second sealing edge 122 and the lid 200, so that the operator can get a more obvious force difference feedback when tearing the lid 200 to the junction of the first sealing edge 121 and the second sealing edge 122, thus achieving a prompting effect for the operator. On the other hand, it can also reduce the difficulty for the operator to tear the lid 200 from the second sealing edge 122.

[0059] In some embodiments, along the extension direction perpendicular to the main body segment 1213, the dimension H2 of the main body segment 1213 satisfies: 8≤H2≤12mm. For example, the dimension H2 of the main body segment 1213 can be 8mm, 9mm, 10mm, 11mm, 12mm, etc., thereby ensuring the reliability of the connection between the sealing structure 120 and the box cover 200.

[0060] It is understandable that, based on the above dimensional relationships, the dimensions of the transition section 1214 in the direction perpendicular to the main body section 1213 and the dimensions of the second sealing portion 122 along the second direction Y can be obtained from the dimensions of the main body section 1213 in the direction perpendicular to itself.

[0061] In some embodiments, the sealing structure 120 has at least one corner portion, the width of which is greater than or equal to 12 mm and less than or equal to 15 mm. The corner portion can be located between any two portions of the sealing structure 120 extending in different directions. By rationally designing the width of the corner portion, a variable diameter design with gradually increasing sealing width can be formed at the corner of the sealing structure 120, thereby further improving the heat sealing reliability between the sealing structure 120 and the lid 200.

[0062] Please see Figure 4 In some embodiments, the box body 100 includes a first edge S1, a second edge S2, a third edge S3, and a fourth edge S4 that are joined end to end, and there are two second sealing portions 122; the tear-off end K3 is disposed near the junction of the first edge S1 and the fourth edge S4, and the two second sealing portions 122 are respectively located at the first edge S1 and the fourth edge S4; or, the tear-off end K3 is disposed near the junction of the first edge S1 and the fourth edge S4, and the two second sealing portions 122 are respectively located at the second edge S2 and the third edge S3; or, the tear-off end K3 is located at the fourth edge S4, and the two second sealing portions 122 are respectively located at the first edge S1 and the third edge S3.

[0063] The box body 100 can be a square box, and the box body 100 includes a first edge S1, a second edge S2, a third edge S3, and a fourth edge S4. The aforementioned four edges are connected end to end to form the peripheral edge of the box body 100. There are two second sealing edges 122, and the two second sealing edges 122 can have the same shape and size.

[0064] In some embodiments, the tear-off end K3 can be located near the junction of the first edge S1 and the fourth edge S4. In this case, the first direction X can be approximately parallel to the line connecting the junction of the first edge S1 and the fourth edge S4 to the junction of the second edge S2 and the third edge S3. The box cover 200 is approximately torn off from the tear-off end K3 along the diagonal direction of the packaging box, thereby reducing the difficulty of tearing off the box cover 200.

[0065] In this embodiment, the number of functional areas K1 can be two, while the number of stable areas K2 can be one. The two second sealing portions 122 can be as follows: Figure 4 The two second sealing portions 122 are located at the first edge S1 and the fourth edge S4, respectively, or at the second edge S2 and the third edge S3, respectively, so that the area corresponding to the two functional areas K1 can be adjusted, that is, the size of the storage slots in the two functional areas K1 can be adjusted so that they can be adapted to various types of functional components.

[0066] In other embodiments, the tear-off end K3 is located at the fourth edge S4, in which case the first direction X can be parallel to the extending direction of the first edge S1 or the third edge S3. In the embodiments of this application, the number of functional areas K1 can be greater than or equal to two, and the number of stabilizing areas K2 can correspond to the number of functional areas K1. The two second sealing portions 122 are respectively located at the first edge S1 and the third edge S3, and the two second sealing portions 122 can be arranged opposite each other along the second direction Y.

[0067] Please continue reading. Figure 4 In some embodiments, the sealing structure 120 includes a sealing portion 123 and a recessed portion 124. The recessed portion 124 is located on the side of the sealing portion 123 facing away from the functional area K1. The boundary line between the sealing portion 123 and the recessed portion 124 intersects with the first direction X. The recessed portion 124 is recessed relative to the sealing portion 123 on the side away from the lid 200. The lid 200 is heat-sealed to the sealing portion 123.

[0068] The boundary line between the sealing portion 123 and the recessed portion 124 intersects with the first direction X. In some embodiments, the boundary line is perpendicular to the first direction X. By reasonably setting the direction and position of the boundary line, it can play a guiding role when the lid 200 is torn off, thereby reducing the difficulty of tearing the lid 200.

[0069] In some embodiments, a guide protrusion 125 is formed on the recessed portion 124, and the guide protrusion 125 is spaced apart from the tear-off seal portion 123. The guide protrusion 125 is formed on the side surface of the recessed portion 124 facing the lid 200, and the shape of the guide protrusion 125 can be various, for example, the guide protrusion 125 can be elongated. The guide protrusion 125 is spaced apart from the tear-off seal portion 123, and the lid 200 is separated from the recessed portion 124. The guide protrusion 125 can reduce the difficulty of tearing the lid 200 when it is torn off.

[0070] Please see Figure 5 In some embodiments, a pre-fold line P is formed on the side of the lid 200 facing away from the box body 100. The pre-fold line P extends perpendicularly to the first direction X. The pre-fold line P is located at the intersection of the first functional area K1 and the corresponding stable area K2, so as to further remind the operator, further reduce the risk of the lid 200 being accidentally torn, and reduce the possibility of deviation of the functional components during the calibration process.
