Description

Technical Field

[0001] The utility model relates to a degradable packaging box with a planting function, belonging to the field of packaging boxes. Background Art

[0002] In the field of product packaging, packaging boxes serve as a key vehicle for product protection, transportation, storage, and display. Their material selection and structural design have a profound impact on environmental impact and resource utilization efficiency. Currently, the packaging boxes widely used in the market are primarily made of traditional plastics (such as polyethylene (PE), polypropylene (PP), and polystyrene (PS)) or ordinary, untreated cardboard (such as corrugated cardboard and paperboard). However, these two mainstream packaging formats have significant and urgently needed shortcomings in terms of sustainability and functionality:

[0003] The current mainstream plastic and ordinary paper box packaging constitute a long-term source of environmental pollution due to their non-degradable or difficult-to-degrade material properties; at the same time, their highly single functional design leads to a short life cycle, and they become waste after the product is unpacked, resulting in significant waste of resources and low utilization efficiency. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and to provide a degradable packaging box with a planting function.

[0005] A degradable packaging box with a planting function comprises an outer shell and a detachable box body. The box body is provided with a plurality of slots for placing items, each slot having a sealed cavity at its bottom for accommodating seeds for planting. After using the product, consumers can simply use the original packaging cavity for simple planting without having to purchase a separate seedling container, transforming the discarded packaging into a "planting vessel." This planting experience encourages consumers to pay attention to nature and environmental protection, enhancing their awareness and enthusiasm for environmental protection, extending the lifespan of the box body, and increasing the added value of the product. The packaging box is no longer simply "waste," but serves as a practical vehicle for home gardening and small-scale landscaping, promoting the secondary use of resources.

[0006] Preferably, the inner wall shared by two adjacent receiving grooves can be torn and separated from the adjacent inner walls along the edge lines on both sides of the inner wall. Through the tearable shared inner wall structure, the user can flexibly merge several adjacent small cavities into a larger planting space according to the size and quantity requirements of different seeds or seedlings. After tearing off the partition, several receiving cavities can be recombined into a "mini seedling tray" or "potted plant tray", further enhancing the secondary utilization value of the packaging box. Although a tearable structure is designed, during production, it is only necessary to engrave dotted lines or prefabricated breakpoints that meet the tear strength requirements on both sides of the inner wall, without the need to replace materials or add complex components. This not only ensures the structural strength of the product, but also provides a customizable assembly method without significantly increasing manufacturing costs.

[0007] Furthermore, the storage chamber is provided at the bottom of the storage tank via a detachable isolation plate. The isolation plate is detachably connected to the inner wall of the storage chamber on all sides, and the isolation plate can be torn and separated from the inner wall of the storage tank along the edges on all sides. During the transportation and display stages of the goods, the isolation plate strictly separates the storage chamber where the seeds are located from the space of the upper storage tank (used to place the goods), which can effectively prevent the seeds or seedling medium (such as soil, nutrient soil) from being contaminated or squeezed out of the goods; consumers only need to press or tear the isolation plate along the preset edges to completely remove the seed chamber at the bottom, together with the seeds and seedling medium pre-placed therein; compared to the traditional method of preparing flower pots or planting containers separately, this structure can be used directly as a seedbed without the need for additional tools or containers, which simplifies the operation process and improves the user experience. During production, it is only necessary to reserve an isolation plate of corresponding size and shape at the bottom of the storage tank, and set controllable tearing points (dashed lines or pressed lines) on all sides. The process is simple and does not require additional molds or production steps.

[0008] Furthermore, the chamber contains a coconut husk substrate for planting seeds. Coconut husk is rich in organic matter and has excellent water retention and air permeability. By pre-loading the chamber with coconut husk, consumers can simply plant seeds on the coconut husk surface and maintain proper moisture after removing the isolation panel, eliminating the need for additional soil or substrate.

[0009] Preferably, the outer shell and the housing are integrally formed of a degradable material. This integrally formed degradable material maintains the same degradation characteristics throughout the entire packaging box, avoiding the potential for differences in degradation rates that may arise from splicing multiple materials. This allows the products to be uniformly composted or biodegraded after use, achieving true zero-residue, zero-pollution results.

[0010] Furthermore, the degradable material is bagasse pulp, polylactic acid (PLA), or other degradable materials. Bagasse, the solid byproduct left after sugarcane juice extraction, is readily available and inexpensive. Pulping it for use in packaging production significantly reduces raw material costs. Bagasse itself has a natural cellulose structure, and the resulting packaging can be decomposed by microorganisms in natural environments (such as compost or soil). The degradation products are non-toxic to the soil and can even serve as organic matter to improve soil quality. PLA's inherently high tensile strength and stiffness ensure that the packaging has excellent impact and pressure resistance during daily use, handling, and stacking, protecting the contents from damage.

[0011] Preferably, the housing is provided with a mounting groove, the box body is embedded in the mounting groove, and the outer side of the box body is provided with a pull-tab for separation from the housing. By pre-forming a mounting groove in the housing that matches the contour of the box body, the box body can be directly inserted and positioned, and can be fixed in the housing without the need for additional screws or adhesives. The outer side of the box body can be separated from the housing along the edge of the mounting groove by simply pulling lightly along the pre-set pull-tab, without peeling off the entire packaging or using tools, significantly reducing the number of disassembly steps for the user. The structure of the mounting groove and the box body pull-tab can be designed and molded in one step using the same mold, eliminating the need for subsequent secondary cutting or bonding, reducing process steps and reducing production complexity.

[0012] Furthermore, the outer shell is provided with an observation window for viewing the contents of the box, which is sealed with a transparent film. Through the observation window covered by the transparent film, consumers can visually view the goods inside the box without opening the package. The transparent film not only ensures the transparency of the observation window, but also uses a sealing process around the film and the outer shell to relatively isolate the interior of the box from the external environment.

[0013] Furthermore, the housing is equipped with a humidity indicator strip for observing soil moisture. This strip is a cobalt chloride test paper. For consumers unfamiliar with gardening, it is difficult to determine the actual moisture content of the substrate by touch or visual inspection. The humidity indicator displays an intuitive color change, allowing accurate information to be obtained without removing the cover or touching the substrate, reducing the learning curve for first-time growers.

[0014] Preferably, the bottom of the chamber is provided with a drainage hole. After watering, excess water can be drained through the bottom drainage hole, preventing water accumulation in the coconut husk matrix due to prolonged overwetting. The drainage hole can be created in one go within the mold design, eliminating the need for subsequent drilling or additional processing, maintaining a simple and economical production process.

[0015] The beneficial effects of the present invention are as follows: after the product is used, consumers do not need to purchase a separate seedling container, and can directly use the holding cavity of the original packaging box for simple planting, turning the discarded packaging into a "planting vessel"; through the planting experience, consumers are guided to pay attention to nature and environmental protection concepts, enhance their environmental awareness and enthusiasm for participation, extend the service life of the box, and increase the added value of the product; the packaging box is no longer a simple "waste", but serves as a practical carrier for home gardening and small-scale greening, promoting the secondary utilization of resources.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0022] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0023] The directional and positional terms used in this invention, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are used solely to refer to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0024] like Figure 1-3 The figure shows an embodiment of a degradable packaging box with a planting function according to the present invention, comprising an outer shell 1 and a box body 2 detachable from the outer shell 1. The box body 2 is provided with a plurality of slots 21 for placing items arranged at intervals. The bottom of the slots 21 is sealed with a receiving cavity 22 for accommodating seeds for planting. After using the product, consumers do not need to purchase a separate seedling container. They can directly use the receiving cavity 22 of the original packaging box for simple planting, transforming the discarded packaging into a "planting vessel". Through the planting experience, consumers are guided to pay attention to nature and environmental protection concepts, enhance their environmental awareness and enthusiasm for participation, extend the service life of the box body 2, and increase the added value of the product. The packaging box is no longer simply "waste", but serves as a practical carrier for home gardening and small-scale greening, promoting the secondary use of resources.

[0025] The inner wall shared by two adjacent receiving grooves 21 can be torn and separated from the adjacent inner walls along the edges on both sides of the inner wall. Through the tearable shared inner wall structure, the user can flexibly merge several adjacent small cavities into a larger planting space according to the size and quantity requirements of different seeds or seedlings. After tearing off the partition, several receiving cavities 22 can be recombined into a "mini seedling tray" or "potted plant tray", further enhancing the secondary utilization value of the packaging box. Although a tearable structure is designed, during production, it is only necessary to engrave dotted lines or prefabricated breakpoints that meet the tear strength requirements on both sides of the inner wall, without the need to replace materials or add complex components. This not only ensures the structural strength of the product, but also provides a customizable assembly method without significantly increasing manufacturing costs.

[0026] The accommodating chamber 22 is provided at the bottom of the accommodating groove 21 via a detachable isolation plate 25. The isolation plate 25 is detachably connected to the inner wall of the accommodating chamber 22 on all sides, and the isolation plate 25 can be torn and separated from the inner wall of the accommodating groove 21 along the edges on all sides. During the transportation and display of goods, the isolation plate 25 strictly separates the accommodating chamber 22 where the seeds are located from the space of the upper accommodating groove 21 (for placing goods), which can effectively prevent the seeds or seedling medium (such as soil, nutrient soil) from being contaminated or squeezed out from the goods. Consumers only need to press or tear the isolation plate 25 along the preset edges to completely remove the seed cavity at the bottom, together with the seeds and seedling medium pre-placed therein. Compared with the traditional method of preparing flower pots or planting containers separately, this structure can be used directly as a seedbed without the need for additional tools or containers, which simplifies the operation process and improves the user experience. During production, it is only necessary to reserve an isolation plate 25 of corresponding size and shape at the bottom of the accommodating groove 21 and set controllable tearing points (dashed lines or pressed lines) around it. The process is simple and does not require additional molds or production processes.

[0027] The chamber 22 also contains a coconut husk substrate for planting seeds. Coconut husk is rich in organic matter and has excellent water retention and air permeability. By pre-loading the chamber 22 with coconut husk, consumers can simply sow seeds directly on the coconut husk surface, maintaining appropriate moisture levels, after removing the isolation panel 25. This eliminates the need for additional soil or substrate for seedling cultivation.

[0028] In the embodiment of the present application, unlike the above-described embodiment, the outer shell 1 and the housing are integrally formed of a degradable material. This integrally formed degradable material maintains the same degradation characteristics throughout the entire packaging box, avoiding the potential problem of varying degradation rates caused by splicing multiple materials. This allows the products to be uniformly composted or biodegraded after use, achieving true zero-residue, zero-pollution results.

[0029] The degradable material is bagasse pulp, polylactic acid (PLA), or other degradable materials. Bagasse, the solid byproduct left after sugarcane juice extraction, is readily available and inexpensive. Pulping it for use in packaging production significantly reduces raw material costs. Bagasse itself has a natural cellulose structure, and the resulting packaging can be decomposed by microorganisms in natural environments (such as compost or soil). The degradation products are non-toxic to the soil and can even serve as organic matter to improve soil quality. PLA also possesses high tensile strength and stiffness, providing the packaging with excellent impact and compression resistance during daily use, handling, and stacking, protecting the contents from damage.

[0030] The shell 1 is provided with a mounting groove 11, and the box body 2 is embedded in the mounting groove 11. The outer side of the box body 2 is provided with a pull-out 23 for separation from the shell 1. By pre-forming a mounting groove 11 that matches the contour of the box body 2 in the shell 1, the box body 2 can be directly embedded and positioned, and can be fixed in the shell 1 without the need for additional screws or adhesives. The outer side of the box body 2 only needs to be gently pulled along the preset pull-out 23 to be separated from the shell 1 along the edge of the mounting groove 11. There is no need to peel off the entire packaging or use tools, which greatly reduces the number of disassembly steps for the user. The structures of the mounting groove 11 and the pull-out 23 of the box body 2 can be designed and molded in one step using the same mold, without the need for subsequent secondary cutting or bonding, thus reducing process links and reducing production complexity.

[0031] In this embodiment of the present application, unlike the above-described embodiment, the outer shell 1 is provided with an observation window 12 for viewing the contents of the box body 2. The observation window 12 is sealed and covered by a transparent film. Through the observation window 12 covered by the transparent film, consumers can visually view the merchandise inside the box body 2 without opening the package. The transparent film ensures the transparency of the observation window 12 and, through the sealing process around the film and the outer shell 1, the interior of the box body 2 is relatively isolated from the external environment.

[0032] In this embodiment of the present application, unlike the previous embodiment, the housing 1 is provided with a humidity indicator strip for observing soil moisture. This indicator strip is a cobalt chloride test strip. For consumers unfamiliar with gardening, it is difficult to determine the actual moisture content of the substrate by touch or visual inspection. The humidity indicator strip displays an intuitive color change, allowing accurate information to be obtained without removing the cover or touching the substrate, reducing the learning curve for first-time growers.

[0033] In this embodiment, unlike the previous embodiment, drainage holes 24 are provided at the bottom of the housing chamber 22. After watering, excess water can be drained through these holes, preventing accumulation of water in the coconut husk substrate due to prolonged moisture. These drainage holes 24 are created in a single, integrated mold design, eliminating the need for subsequent drilling or additional processing, maintaining a simple and economical production process.

[0034] Users can plant the box into the soil or directly use it as a potted plant carrier as needed.

[0035] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.

[0036] Although the present invention has been described with reference to several specific embodiments, it should be understood that the present invention is not limited to the specific embodiments disclosed, and the present invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
