Description

Packing box

Technical Field

The utility model relates to the field of packaging boxes, in particular to the field of paper packaging boxes.

Background

Packages are very common in everyday life and are used to hold a wide variety of items. The packaging box is also a factor considered by people when purchasing goods. For example, aesthetic packages tend to be more attractive to consumers. Besides aesthetics, the interaction between the user and the package is also a major consideration for consumers, as is the ease of removal and functional versatility of the package.

One of the more common storage boxes on the market today has a single cavity and an upper cover covering the cavity. In some cases, the packaged items may be mixed together for packaging, such as in the case of multiple confections. In other cases, the articles may be desired to be sorted, which may require a separate package for each article, or they may be packaged in a box, for example in the form of a most commonly employed package cell. When the upper lid is opened, the packaged item is presented and the package is not attractive to the user for use and unpacking.

wherein the first elastic pushing device has a first compressible pushing body and a first elastic member disposed within and connected to the first compressible pushing body, the first compressible pushing body having a compressed state and an expanded state; when the first compressible push body is in a compressed state, the first resilient member is in a pre-stretched state; when the first set of sub-cartridges is taken out through the main cartridge body outlet, the first compressible pushing body is switched to the expanded state by contraction of the first elastic member to push the second set of sub-cartridges in a first direction to the position to be taken out, and wherein the first compressible pushing body has a single sheet form.

In the packaging box, a plurality of groups of sub-boxes are arranged, after the former group of sub-boxes are taken out, the next group of sub-boxes can be automatically pushed to a position to be taken out through the elastic pushing device, and the compressible pushing main body of the elastic pushing device is in the form of a single piece of sheet, particularly a single piece of paper sheet, so that the packaging box can be formed through simple folding and pasting after one-time stamping of a flat paper board, the material is environment-friendly, the material can be manufactured in batches through a simple process, the folding and pasting operation is simple and easy, the operation is not required to be carried out under special environments, and the operation can be completed without operators with special skills, thereby greatly saving the cost.

In a further embodiment, the sub-cartridge assembly comprises a third set of sub-cartridges disposed rearward of the first set of sub-cartridges in a second direction toward the position to be removed; the package further comprises a second resilient pushing means disposed behind the third set of sub-cartridges in the second direction to bias the third set of sub-cartridges toward the position to be taken out; wherein the second elastic pushing device has a second compressible pushing body and a second elastic member disposed within and connected to the second compressible pushing body, the second compressible pushing body having a compressed state and an expanded state, the second elastic member being in a pre-tensioned state when the second compressible pushing body is in the compressed state; when the second set of sub-cartridges is taken out through the main cartridge body outlet, the second compressible pushing body is switched to an expanded state by the second elastic member to push the third set of sub-cartridges in a second direction to the position to be taken out, and wherein the second compressible pushing body has a single sheet form.

In the same main box body, a plurality of groups of sub boxes pushed in different directions can be arranged, so that the packaging box can be designed according to requirements, for example, according to the shape of the space for placing the packaging box, and the internal space of the packaging box can be utilized as much as possible, thereby realizing the maximum utilization rate. And the elastic pushing device according to the present utility model does not limit the pushing direction, so that it can be used in different pushing directions.

Preferably, the first compressible push body and the second compressible push body each have a strip-like body with two ends connected to form a loop, and when the loop is deployed, two ends of the respective elastic members are connected to two facing connections of the loop. The elastic means realized by the strip-like body are simple in structure and easy to manufacture, and are particularly advantageous in particular for paper sheets, which can be formed by one punching and which have an elasticity tending to spread themselves after the formation of the loop.

Preferably, the strip-shaped body comprises, in order, a first section, a first connecting piece, a second section, a third section, a second connecting piece, and a fourth section, wherein the first section and the third section have the same shape, the second section and the fourth section have the same shape, and the first section and the fourth section are connected to form the ring, and wherein the first connecting piece and the second connecting piece each comprise two symmetrical connecting halves, which are formed by folding the two connecting halves along their folding lines into the inside of the ring and fixing each other. The elastic pushing device formed by the method is easy to fold when flattened and convenient to position in the main box body, can form a relatively stable hexahedral structure when unfolded, and provides a further auxiliary effect when being converted from a compressed state to an unfolded state. Furthermore, the connection for connecting the elastic member is also part of a single piece of sheet material, formed together with the rest in one blanking process, without separate manufacturing.

Preferably, the two connecting halves have hook-shaped slits symmetrical with respect to their fold lines.

Preferably, the first compressible push body and the second compressible push body each have collapsible reinforcement on both sides of the first section and the third section of their strip-like bodies. The collapsible reinforcement is located inside the compressible push body when the compressible push body is in a compressed state, and when the compressible push body is switched to an expanded state, it expands at the same time and assists the resilient expansion action. Upon deployment, the opposing collapsible reinforcement sections may form sides of the compressible push body to provide a complete and compact appearance.

Preferably, a plate-like member is provided on a section of the strip-like body opposite to the section adjoining the inner wall of the package, the plate-like member being dimensioned to extend beyond the section where it is located. Since the plate has a longer dimension, it can cover as much as possible the respective abutment surfaces of the respective group of sub-cartridges in the unfolded state, to provide a uniform and smooth support thereof.

Preferably, the elastic member is an elastic cord or an elastic band, such as a rubber band. Thus, very simple and common components can be used to achieve the elastic function, which results in a significant cost saving.

Preferably, the second direction is perpendicular to the first direction.

Preferably, the pretensioning stress of the first elastic member is greater than the pretensioning stress of the second elastic member. Therefore, after the first group of sub-boxes are taken out, the first elastic pushing device is converted into an unfolding state earlier than the second elastic pushing device, so that the pushing sequence of the corresponding group of sub-boxes is determined, and mutual interference among the sub-boxes and clamping stagnation are avoided.

Preferably, the first set of sub-cartridges is not flush with the third set of sub-cartridges in the second direction. Thus, when the sub-cartridges of the respective sets are pushed in a predetermined order, they can travel smoothly without causing jamming.

Preferably, the package further includes a support portion provided inside thereof, the support portion having a support body provided in the rear of the third group of sub-cartridges and the second group of sub-cartridges in the first direction and the second direction, respectively.

Preferably, the main box outlet is provided on the front wall of the main box and has a recess facing in a direction opposite to the first direction, the support further comprising a first baffle extending from the support body along the front wall of the main box, the first baffle at least partially covering the recess. The recess provides a catch for opening the outlet of the main housing and the first flap at least partially covers the recess such that there is no gap between the lid and the main housing when the package is in the packaged condition, preventing dust from falling into the housing and contaminating the contents.

Preferably, the support portion abuts against a self-locking bottom surface of the main case, and the support portion further includes a second baffle extending from the support body along the self-locking bottom surface. This avoids the problem that the elastic pushing device and the corresponding set of sub-boxes cannot be placed stably due to the unevenness of the self-locking ground, and thus avoids the obstruction from the inner wall of the main box body, for example, when the sub-boxes are pushed, and the jamming phenomenon caused thereby.

Preferably, the first, second and third sets of sub-cartridges respectively include a plurality of sub-cartridges, and the plurality of sub-cartridges in each set are snap-connected to each other.

A further understanding of the nature and advantages of the present utility model will be realized by those skilled in the art by reference to the attached drawings and the corresponding written description. It will be apparent that the described embodiments are some, but not all, embodiments of the utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the utility model, as presented in conjunction with the accompanying drawings, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, the positional or positional relationship indicated by "top", "bottom", "upper", "lower" and the like are based on the positional or positional relationship shown in the drawings, or the positional or positional relationship in which the inventive product is conventionally put in use, are merely for convenience of describing the present utility model and simplifying the description, and are not indicative or implying that the apparatus or element in question must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present utility model. When the placement mode of the packaging box is changed (for example, the packaging box is turned over by a certain angle), a person skilled in the art can understand that the corresponding direction is also changed, and the obtained technical scheme still belongs to the protection scope of the utility model.

In the present utility model, the front wall of the packing box means the side of the main box body of the packing box having the main box body outlet, and the bottom surface means the side of the main box body of the packing box located at the bottom in the usual placing position.

Referring to fig. 1 and 2, fig. 1 and 2 show a schematic perspective view of a package 1 according to the present utility model. The pack 1 comprises a main box 10, which main box 10 has, in the example of fig. 1, the general shape of a hexahedron, which may be a cube or a hexahedron with a rectangular cross section. It should be understood that the main casing 10 is not limited to the form shown in the drawings, but may have other shapes. The main box 10 may be a carton formed by folding paperboard.

As shown in fig. 2, the main casing 10 may be provided with a main casing outlet 11 and a position to be taken 16 corresponding to the main casing outlet. The main box outlet 11 is provided in a front wall 110 of the main box 10, which front wall 110 generally faces the user. The main cartridge outlet 11 may be covered by a lid 13, the upper edge of the lid 13 may be joined to the upper edge 111 of the front wall 110, while the other edges may be joined to the rest of the front wall 110 by frangible lines. When the lid 13 covers the main box outlet 11, it forms part of the front wall 110. In the illustrated example, the main box outlet 11 is located in the upper right hand corner of the front wall 110, it being understood that the main box outlet 11 may be located in other locations on this face.

The position 16 to be removed is shown in fig. 2 in dashed lines, which is a virtual position in the main box 10, i.e. the object of the main box 10 can be removed from the main box outlet 11 when it is in this position 16 to be removed.

The package 1 according to the present utility model is further described below with reference to fig. 3 and 4A to 4D.

As shown, package 1 may include a sub-cartridge assembly 20 (e.g., as shown in fig. 4D). The sub-cartridge assembly 20 may have at least a first set of sub-cartridges 500 and a second set of sub-cartridges 600. A sub-cartridge assembly 20 comprising these sets of sub-cartridges is provided within the main cartridge body 10 and can be withdrawn through the main cartridge body outlet 11. Fig. 3 shows a first set of sub-cartridges 500 being located in the position 16 to be removed. Each set of sub-cartridges may have one or more sub-cartridges, which are arranged in the take-out direction when there are a plurality of sub-cartridges. The multiple sub-cartridges in each group may be snap-fit to each other, for example. In one example, not shown, each sub-cartridge has a tab protruding toward the user and formed with slots on opposite sides that can correspond to the tab, and the tab of the rear sub-cartridge may be inserted into the slot on the front sub-cartridge to form a sub-cartridge array. When the user pulls the foremost one of the set of sub-cartridges at the position to be taken out 16, all of the sub-cartridges in the set can be taken out together.

The arrangement of the sub-cartridge assembly 20 is described below with reference to fig. 5. Fig. 5 is a cross-sectional view of package 1, taken in a plane parallel to front wall 110, to illustrate the arrangement of sub-cartridge assembly 20 inside main cartridge 10 of package 1.

As shown in fig. 5, the sub-cartridge assembly 20 includes a first set of sub-cartridges 500 positioned at the to-be-removed location 16. The sub-cartridge assembly 20 further comprises a second set of sub-cartridges 600 arranged behind the first set of sub-cartridges 500 in a first direction D1 towards the position 16 to be removed. When the first set of sub-cartridges 500 is removed, the second set of sub-cartridges 600 can automatically travel in the first direction D1 and occupy the position 16 to be removed to wait for the user to remove it. To this end, the packet 1 further comprises first elastic pushing means 30 arranged in the first direction (D1) behind the second set of sub-packets 600, which first elastic pushing means 30 are placed in a flattened condition between the bottom of the main packet 10 and the second set of sub-packets 600 in fig. 5. In the flattened condition, the first resilient pushing device 30 has a tendency to expand to bias the second set of sub-cartridges 600 toward the to-be-removed position. Thus, when both the first set of sub-cartridges 500 and the second set of sub-cartridges 600 are placed in the main casing 10, the first elastic pushing means 30 is flattened and pushes the second set of sub-cartridges 600 toward the first set of sub-cartridges 500, and when the first set of sub-cartridges 500 is ejected, the first elastic pushing means 30 automatically pops up to push the second set of sub-cartridges 600 to the to-be-extracted position 16.

In particular and with reference to fig. 7 and 8, the first elastic push device 30 according to the utility model has a first compressible push body 31, which has the form of a single piece of sheet material. Preferably, the first compressible push body 31 is formed from a single piece of paper. For example, the first compressible pushing body 31 may have a strip-like body 310, with two ends of the strip-like body 310 connected to form a loop 310A. The first resilient push device 30 also has a first resilient member 35 disposed within the first compressible push body 31 and connected to the first compressible push body 31. The first elastic member 35 may be, for example, an elastic cord or an elastic band, such as a rubber band.

As shown in fig. 7, the first compressible pusher body 31 may have a compressed state and an expanded state, the first compressible pusher body 31 being shown in the compressed state in the lower half of fig. 7 and the first compressible pusher body 31 being shown in the expanded state in the upper half of fig. 7. In the example of fig. 7, when the first compressible pushing body 31 is in the unfolded state, it presents a hexahedral overall solid shape, the ring 310A has the form of a rectangular ring or a square ring, while the two ends of the first elastic member 35 (e.g. a rubber band) are connected to the substantially diagonal positions of the ring 310A, respectively. It will be appreciated that the first compressible pushing body 31 in the expanded state may also have other forms than hexahedral, the ring 310A may also have other forms than rectangular or square rings, for example, in the form of a circular ring, with both ends of the elastic member connected to both end points of the circular ring diameter.

When the first compressible push body 31 is in the compressed state (lower half of fig. 7), the first resilient member 35 is in a pre-stretched state, having a tendency to spring the first compressible push body 31 up to the expanded state. When the first set of sub-cartridges 500 in the to-be-removed position 16 is removed through the main cartridge body outlet 11, the pressure above the second set of sub-cartridges 600 is lost and only the force applied by the first elastic pushing means 30 in the first direction is applied. At this time, the first elastic member 35 is contracted, and the first compressible pushing body 31 is converted to the expanded state by the contraction of the first elastic member 35 to push the second group of sub-cartridges 600 to the to-be-taken out position 16 in the first direction D1. At this point, the deployed first resilient pushing device 30 occupies the original position of the second set of sub-cartridges 600. In fig. 5, the first direction D1 is a vertically upward direction, that is, the first elastic pushing device 30 is capable of pushing up the second group of sub-cartridges 600. At this time, the user may still take out the second set of sub-cartridges 600 through the main cartridge body outlet 11.

In the package 1 according to the utility model, a plurality of sets of sub-boxes are provided, after the former set of sub-boxes is taken out, the next set of sub-boxes can be automatically pushed to the position to be taken out by the elastic pushing device, and the compressible pushing body of the elastic pushing device is in the form of a single piece of sheet, in particular a single piece of paper sheet, so that the package can be formed by simply folding and pasting after one-time stamping of a flat paper board, the material is environment-friendly, the material can be manufactured in batches by a simple process, the folding and pasting operation is simple and easy, the operation is not required to be performed in a special environment, and the operation can be completed without operators with special skills, thereby greatly saving the cost.

The main casing 10 of the pack 1 according to the present utility model may accommodate therein a plurality of sets of sub-cartridges that can be ejected in different directions. Specifically, as shown in fig. 5, the sub-cassette assembly 20 may include a third set of sub-cassettes 700, the third set of sub-cassettes 700 being disposed rearward of the first set of sub-cassettes 500 in a second direction D2 toward the to-be-removed location 16. In this embodiment, the second direction D2 may be perpendicular to the first direction D1, for example, and when the first direction D1 is a vertical direction, the second direction D2 is a horizontal direction. The package 1 further comprises a second elastic pushing means 40 arranged in a second direction D2 behind said third set of sub-cartridges 700 to bias the third set of sub-cartridges 700 towards said position to be removed 16. The second resilient pushing device 40 is shown in fig. 5 in a flattened state disposed between the side walls of the main housing 10 and the second set of sub-housings 700. In the flattened condition, the second resilient pushing device 40 has a tendency to expand to bias the third set of sub-cartridges 700 toward the to-be-removed position 16.

Similar to the first elastic push device 30, the second elastic push device 40 has a second compressible push body 41 and a second elastic member 45, the second elastic member 45 being disposed within the second compressible push body 41 and connected to the second compressible push body 41. The second compressible push body 41 has the form of a single piece of sheet material, preferably formed from a single piece of paper. Similar to the first compressible push body 31, the second compressible push body 41 may have a strip-like body 410 (fig. 8), with the ends of the strip-like body 410 being joined to form a loop 410A (fig. 7). The second elastic member 45 of the second elastic pushing device 40 may be, for example, an elastic cord or an elastic band, such as a rubber band. As shown in fig. 7, the second compressible push body 41 may also have a compressed state and an expanded state, and when the second compressible push body 41 is in the expanded state, it takes on a hexahedral overall three-dimensional shape, the ring 410A has the form of a rectangular ring or a square ring, and both ends of the second elastic member 45 (e.g., a rubber band) are respectively connected to the substantially diagonal positions of the ring 410A. It should be understood that the second compressible push body 41 in the expanded state may have other forms than hexahedral, and the ring 410A may have other forms than rectangular or square rings.

When the second compressible push body 41 is in the compressed state, the second resilient member 45 is in the pre-tensioned state, having a tendency to spring the second compressible push body 41 up to the expanded state. When the second group of sub-cartridges 600 at the to-be-taken-out position 16 is taken out through the main-cartridge outlet 11, the second compressible pushing body 41 is switched to the expanded state by the second elastic member 45 to push the third group of sub-cartridges 700 to the to-be-taken-out position 16 in the second direction D2. At this point, the deployed second elastic pushing device 40 occupies the original position of the third set of sub-cartridges 700.

The specific structure of the first compressible push body 31 and the second compressible push body 41 is described below with reference to fig. 7 and 8. As previously mentioned, the two ends of the respective strip-like bodies 310, 410 of the first 31 and second 41 compressible push bodies are connected to form a

loop

310A, 410A, and when the

loop

310A, 410A is unfolded, the two ends of the respective elastic member 35, 45 are connected to the two facing connection portions 318, 319 (belonging to the first 31) and 418, 419 (belonging to the second 41) of said loop. The connections 318, 319 and 418, 419 may be located at the diagonals of the respective rings. In the compressed state of the compressible push body 31, 41 the resilient members 35, 45 are in a pre-tensioned state, and when the force applied to the compressible push body 31, 41 to bring it in a flattened state is removed, the resilient members 35, 45 contract, pulling the opposing connection portions towards each other, whereby the compressible push body 31, 41 returns from the flattened state to a stereoscopic state to apply a push force to a set of sub-cartridges adjacent thereto.

Fig. 8 shows a specific embodiment of the first and second compressible push bodies 31, 41, and fig. 8 shows a state in which they have not been folded. Since the first and second compressible push bodies 31, 41 are similar in structure, they are not shown separately in separate views. The first and second compressible push bodies 31, 41 are in the form of a single piece of sheet material, such as paper sheet material, which may be formed by one-time stamping, with portions thereof lying in a plane prior to folding. The strip-shaped body 310, 410 includes, in order, a first section 311, 411, a first connecting piece 321, 421, a second section 312, 412, a third section 313, 413, a second connecting piece 322, 422, and a fourth section 314, 414. The sections and tabs are joined end to end in the order described above to form a longitudinal strip of a length, with the joints having fold lines, as shown in figure 8.

The first sections 311, 411 have the same shape as the third sections 313, 413, the second sections 312, 414 have the same shape as the fourth sections 314, 414, and the first sections and the fourth sections are connected to form the ring. The loops thus formed are square and rectangular loops, wherein the first sections 311, 411 face the third sections 313, 413 and the second sections 312, 414 face the fourth sections 314, 414. The latticed portions on the compressible push bodies 31, 41 shown in fig. 8 are adhesive tabs that, when folded, adhere to the corresponding portions to form a stable pop-up structure. The elastic pushing device formed by the method is easy to fold when flattened and convenient to position in the main box body, can form a relatively stable hexahedral structure when unfolded, and provides a further auxiliary effect when being converted from a compressed state to an unfolded state.

To form the connection in a single piece of sheet material, the first connection tab 321, 42 comprises two

symmetrical connection halves

321A, 321B, 421A, 421B and the second connection tab 322, 422 comprises two

symmetrical connection halves

322A, 322B, 422A, 422B, the respective two connection halves being folded along their fold lines towards the inside of the

loop

310A, 410A and secured to each other to form the connection 318, 418 and 319, 419. Thereby, the connection for connecting the elastic member is also part of the single piece of sheet material, formed together with the rest in one blanking process, without separate manufacturing.

Since the connection pieces 322, 422 are similar to the connection pieces 321, 421, the connection pieces 321, 421 are described only as examples, and the connection pieces 322, 422 may be structured with reference to the connection pieces 321, 421. In the example shown in fig. 8, the connection halves 321A, 321B and 421A, 421B have a trapezoidal form and are connected to each other at the short sides of the trapezoid. Fold

lines

321L, 421L are formed at the short sides. The two connecting

halves

321A, 321B and 421A, 421B have hook-shaped

slits

321C, 321D and 421C, 421D that are symmetrical with respect to their

fold lines

321L, 421L. Taking the example of hook-shaped

slits

321C, 321D, their root portions are located at the fold line 321L, and they communicate with each other here, thereby forming a channel (as shown in FIG. 7) that allows the elastic member to pass through after folding. The ends of the hook-shaped

slits

321C, 321D inside the connection halves 321A, 321B may have a hooked shape to stably receive the ends of the elastic member after folding.

Assuming that one side of the strip-like bodies 310, 410 shown in fig. 8 is the outside after they are folded into a loop, when folded, the connecting

halves

321A, 321B are folded along a fold line 321L in the direction into the page, preferably the opposite faces of the connecting

halves

321A, 321B can be secured together to form a stable connection.

The connecting part formed by the method has stable structure, does not need to be manufactured separately by using materials except a single piece of sheet material, reduces manufacturing process steps and saves cost.

As also shown in fig. 8, in order to make the structure of the first and second compressible push bodies 31 and 41 more stable, the first and second compressible push bodies 31 and 41 each have

foldable reinforcements

331, 332 and 333, 334 on both sides of the first and third sections 311, 411, 313, 413 of their strip-like bodies. The

collapsible reinforcement

331, 332 and 333, 334 may have the form of a right triangle, one of the right triangle sides connecting the longitudinal edges of the first sections 311, 411. After folding, the adhesive tabs of the collapsible reinforcement 331, 332 are adhered to the respective longitudinal edges of the second section 312, and likewise the adhesive tabs of the

collapsible reinforcement

333, 334 are adhered to the respective longitudinal edges of the fourth section 314. As also shown in fig. 8, the collapsible reinforcement parts are symmetrical right triangles, whereby when the resulting compressible, push body is in an unfolded state, the hypotenuse of collapsible reinforcement part 331 is adjacent to the hypotenuse of collapsible reinforcement part 333 and covers the sides of rectangular or square ring 310A, as are

collapsible reinforcement parts

333 and 334, thereby forming a substantially closed, resilient push device. Thus, the elastic pushing device obtains a compact and attractive appearance.

The collapsible reinforcement 331 may have a fold line 331L, which fold line 331L may divide the collapsible reinforcement 331 into two symmetrical parts, which may extend perpendicularly from the right-angled vertex of a right triangle towards the hypotenuse, for example. When in the flattened state, the fold line 331L is located inside the loop, whereby the collapsible reinforcement 331 is also hidden inside the loop, i.e. not visible from the outer face of the loop. The collapsible reinforcement 331 may also have a small collapsible portion 3310 at its free edge, which small collapsible portion 3310 collapses outwardly when flattened, i.e. in the opposite direction to the rest of the collapsible reinforcement 331. Other collapsible reinforcements 332-334 may also have the same arrangement. Thus, the large portion of the collapsible reinforcement 331 and the small collapsible portion 3310, which collapse in opposite directions when expanded, provide better spring force and support for the compressible push body 21 to transition to the expanded state.

In a preferred embodiment, as shown in fig. 8, the strip-like bodies 310, 410 are provided with plate-like members 36, 46. The plate members 36 and 46 may have a similar structure and thus will be described by way of example only with respect to the plate member 36. The plate 36 is provided on a section (313 in fig. 8) of the strip-like body opposite to the section (311 and 314 in fig. 8) adjoining the inner wall of the package, the plate 36 extending beyond the section where it is located. The plate 36 may be a flat paperboard. Taking the embodiment shown in fig. 8 as an example, in the compressed state, the first section 311 and the fourth section 314 abut against the inner wall, such as the bottom wall, of the main case 10, and the second section 312 and the third section 313 abut against the bottom of the second set of sub-cases 600. When sprung to the deployed state, only the first section 314 abuts the inner wall of the main casing 10, the second and fourth sections 312, 314 extend in a generally vertical direction, and the three third sections 313 are formed to support and contact the faces of the second set of sub-cartridges 600. The plate 36 fixed to the third section 313 has a longer longitudinal dimension, so that in the unfolded state it can cover as much as possible the respective abutment surfaces of the second set of sub-cartridges 600 to provide a uniform and smooth support thereof.

The construction of the second elastic pushing device 40 is similar to that of the first elastic pushing device, except that its arrangement inside the main casing 10 is adjusted according to its pushing direction.

Further, after the first group of sub-cartridges 500 is taken out, the order in which the first elastic pushing means 30 and the second elastic pushing means 40 are sprung may be determined according to the pretensioning stress of their respective elastic members. In the example shown in fig. 5, the pretensioning stress of the first elastic member 35 is greater than the pretensioning stress of the second elastic member 45, whereby after the first group of sub-cartridges 500 is taken out, the first elastic pushing means 30 is first switched to the expanded state, so that the second group of sub-cartridges 600 will preempt the position 16 to be taken out. The second resilient pushing device 40 will not expand until after the second set of sub-cartridges 600 is removed.

In addition, in order to avoid jamming by the third set of sub-cartridges 700 when the second set of sub-cartridges 600 is pushed in the first direction D1, the first set of sub-cartridges 500 is not flush with the third set of sub-cartridges 600 in the second direction D2. In the example shown in fig. 5, it can be seen that the top surface of the second set of sub-cartridges 600 is slightly higher than the bottom surface of the third set of sub-cartridges 700. In another embodiment, not shown, the top surface of the second set of sub-cartridges 600 may be slightly lower than the bottom surface of the third set of sub-cartridges 700. Thus, when the sub-cartridges of the respective sets are pushed in a predetermined order, they can travel smoothly without causing jamming.

In order to position the groups of sub-cartridges inside the main cartridge body, the package 1 further comprises a support portion 50 provided inside thereof, as shown in particular in fig. 6. The support portion 50 has a support body 51, and the support body 51 may have a substantially hexahedral form, for example. The relative positional relationship of the support body 51 and each sub-cartridge assembly can be referred to fig. 5. As shown, the support body 51 is disposed rearward of the third set of sub-cartridges 700 in the first direction D1 and rearward of the second set of sub-cartridges 600 in the second direction D2. The support body 51 may be fixed with respect to the main casing 10, and may be adhered to an inner wall of the main casing 10, for example.

Further, the support 50 may further include a first baffle 55 extending from the support body 51 along the front wall 110 of the main casing 10. Meanwhile, the main box outlet 11 has a recess 115, and the recess 115 is opposite to the first direction D1. The recess 115 provides a catch for opening the lid 13. The first flap 55 of the support 50 may at least partially cover the recess 115, whereby there is no gap between the lid 13 and the main casing 10 when the package 1 is in the packaged state, preventing dust from falling into the casing and contaminating the contents.

In some cases, the main cartridge 10 may have a self-locking bottom surface. Such self-locking bottom surfaces are often uneven, whereby tilting occurs when groups of sub-cartridges and elastic pushing means are placed on the self-locking bottom surface, whereby sub-cartridges are also hindered by e.g. inner walls from the main cartridge body when being pushed, resulting in jamming. To solve this problem, the supporting portion 50 further includes a second barrier 56 extending from the supporting body along the self-locking bottom surface, and the corresponding elastic pushing means and the corresponding group of sub-cartridges can be smoothly stacked on the flat second barrier 56, and the corresponding pushing action can be smoothly performed.

The packaging box can provide a plurality of discrete spaces to meet the requirement of object classification, and each classification space (namely a plurality of groups of sub-boxes) can be automatically sprung by an elastic pushing mechanism which is environment-friendly and simple to manufacture in the use process, and the whole packaging box can be made of paper materials, and is light in weight and environment-friendly. The elastic pushing device adopts a single sheet form, can be formed by blanking for one time, has simple process and is convenient for batch manufacturing and transportation. And the elastic pushing device according to the present utility model does not limit the pushing direction, so that it can be used in different pushing directions.
