Description

Technical Field

[0001] This application relates to the field of packaging materials technology, and in particular to a foam plastic for packaging a heater. Background Technology

[0002] Currently, as a common household appliance, the outer shell of a space heater is mostly made of plastic, and the body has vulnerable parts such as air outlets, control panels, and power cord interfaces. Therefore, in order to reduce the damage rate during transportation and storage, appropriate foam plastic is needed to package and support the space heater.

[0003] For example, a foam plastic material with application number "CN201920484105.7" includes a main packaging material and a secondary packaging material. The main packaging material has a main storage groove on its front side facing inward, and a deeper edge storage groove at one end of the main storage groove. The main packaging material has a first crease on its front side that runs vertically and horizontally through the main storage groove and the edge storage groove, and a second crease in the longitudinal direction is provided at the center of the back side of the main packaging material. The secondary packaging material has a secondary storage groove on its front side, and a third crease with the width center as a reference. The secondary packaging material has a fourth crease on its back side that corresponds to the third crease. The beneficial effect of this utility model is that it has a detachable structure, which allows it to be applied to the packaging protection of items of different sizes and materials under the same design style, which not only saves packaging costs, but also benefits green and environmentally friendly sustainable development.

[0004] However, the existing foam plastic used for packaging heaters has the following drawbacks: for example, after the existing foam plastic is used to package the heater, it still needs to be inserted into the packaging box for storage and transportation. However, when the foam is inserted into the packaging box, the gap between it and the packaging box is small. When it is necessary to separate the foam from the packaging box later, it is difficult to remove the foam intact without damage. Utility Model Content

[0005] The purpose of this application is to solve the problem that existing foam still needs to be inserted into the packaging box for warehousing and transportation, but when the foam is inserted into the packaging box, the gap between the foam and the packaging box is small, making it difficult to remove the foam intact and undamaged when it needs to be separated from the packaging box later.

[0006] To achieve the above objectives, the technical solution adopted in this application is: a foam plastic for packaging a heater, including a packaging box, wherein a lower support foam is embedded inside the packaging box; The top of the lower support foam has a groove for placing the heater, which is the lower mold cavity. The outer side of the lower support foam has a longitudinal groove, which is an insertion groove for the user's hand to insert. Insertion grooves are provided on both the left and right sides of the lower support foam. The inside of the insertion groove has a gripping groove for hand holding.

[0007] As a preferred embodiment, anti-collision posts are fixedly connected to the outer side of the lower support foam. The anti-collision posts are made of foam, and anti-collision posts are fixedly connected to the four corners of the outer side of the lower support foam.

[0008] As another preferred embodiment, the top of the lower support foam is provided with a slot, which is a positioning slot, and the top of the lower support foam is fitted with an upper support foam.

[0009] Further preferably, the bottom end of the upper supporting foam is provided with a groove, which is the upper mold cavity, and the upper mold cavity has the same structure as the lower mold cavity.

[0010] As a preferred embodiment, the upper mold cavity is located directly above the lower mold cavity, and anti-collision posts are also fixedly connected to the four outer corners of the upper supporting foam.

[0011] As another preferred embodiment, the upper support foam has two insertion slots facing each other on both the left and right sides, and these insertion slots are connected to the insertion slots on the left and right sides of the lower support foam.

[0012] In a further preferred embodiment, the insertion slot on the outer side of the upper support foam is also provided with a gripping slot for the user's hand to insert.

[0013] As a preferred embodiment, a foam insert is fixedly connected to the bottom end of the upper supporting foam, and the foam insert has a rectangular frame structure.

[0014] Alternatively, the foam insert is matched with a positioning slot formed at the top of the lower support foam, and the foam insert and the positioning slot together form a sealing structure.

[0015] Further preferably, reinforcing foam is fixedly connected to both the bottom surface of the lower supporting foam and the top surface of the upper supporting foam, and the reinforcing foam is arranged in an X shape.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: (1) In this utility model, by opening insertion slots on the left and right sides of the lower support foam and connecting the insertion slots of the upper support foam with the insertion slots of the lower support foam, and setting a holding slot inside the insertion slot, a clear and stable force application structure is provided for the user. The user does not need to use additional tools, but can transmit the pulling force by simply inserting his / her hand into the insertion slot and holding the holding slot. This completely avoids the situation of uneven force on the foam and damage caused by the lack of an effective force application point, and ensures that the foam assembly can be completely and undamagedly separated from the inside of the packaging box, thus fundamentally solving the technical pain points of the prior art. (2) In this utility model, the upper mold cavity and the lower mold cavity are adapted and combined to form a double-layer wrapping of the heater, which can accurately fit the shape of the heater and effectively protect the vulnerable parts such as the air outlet and control panel of the heater, and avoid the vulnerable parts from being damaged by friction or collision with the foam structure during transportation; at the same time, the anti-collision posts at the four corners of the lower support foam and the upper support foam can buffer the collision force of the external environment on the packaging box during storage and transportation, reduce the transmission of impact force to the heater, and the X-shaped reinforced foam can further enhance the structural strength of the upper and lower support foams, and prevent the foam itself from losing its protective effect due to deformation by external force. It has achieved an innovative improvement over the existing technology in terms of comprehensive protection and structural stability. Attached Figure Description

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] like Figure 1-5 The illustrated foam packaging for a heater includes a packaging box 1, with a lower support foam 2 embedded inside the packaging box 1. The top of the lower support foam 2 has a groove for placing the heater, which is the lower mold cavity 2014. A longitudinal groove is formed on the outer side of the lower support foam 2; this longitudinal groove is an insertion groove 2011 for the user's hand to insert. Insertion grooves 2011 are formed on both the left and right sides of the lower support foam 2. A gripping groove 2012 for hand holding is formed inside the insertion groove 2011. Reinforcing foam 301 is fixedly connected to the bottom surface of the lower support foam 2 and the top surface of the upper support foam 3. The solid foam 301 is arranged in an X shape. By embedding the lower support foam 2 inside the packaging box 1, the heater is stably placed by using the lower mold cavity 2014 at the top of the lower support foam 2. At the same time, insertion slots 2011 are set on the left and right sides of the lower support foam 2, and a gripping slot 2012 is opened inside the insertion slot 2011. This allows the user to insert their hand into the insertion slot 2011 and then hold the foam through the gripping slot 2012. This effectively solves the problems of small gap between the foam and the packaging box 1, difficulty in removal, and easy damage, and achieves complete removal of the foam.

[0028] The lower support foam 2 is fixedly connected to the outer side of the anti-collision posts 201. The anti-collision posts 201 are made of foam, and anti-collision posts 201 are fixedly connected to the four corners of the lower support foam 2. The top of the lower support foam 2 is provided with a slot, which is a positioning slot 2013. The upper support foam 3 is installed on the top of the lower support foam 2. By fixing the anti-collision posts 201 of foam structure to the outer side of the lower support foam 2 and setting anti-collision posts 201 at the four corners of the lower support foam 2, the anti-collision posts 201 can buffer the impact force of the outside on the four corners of the lower support foam 2, reduce the damage to the lower support foam 2 and the internal heater during transportation and storage, and improve the impact protection effect of the packaging.

[0029] The upper support foam 3 has a groove at its bottom end, which is the upper mold cavity 3012. The upper mold cavity 3012 has the same structure as the lower mold cavity 2014. The upper mold cavity 3012 is located directly above the lower mold cavity 2014. Anti-collision posts 201 are also fixedly connected to the four outer corners of the upper support foam 3.

[0030] The upper support foam 3 has two opposite insertion slots 2011 on its left and right sides, which are connected to the insertion slots 2011 on the left and right sides of the lower support foam 2. The insertion slots 2011 on the outside of the upper support foam 3 also have grip slots 2012 inside, which are used for the user's hand to insert. The positioning slot 2013 is opened at the top of the lower support foam 2, and the upper support foam 3 is installed at the top of the lower support foam 2. The positioning slot 2013 can provide precise positioning for the installation of the upper support foam 3, ensuring that the upper support foam 3 and the lower support foam 2 are aligned. At the same time, the upper support foam 3 can work with the lower support foam 2 to form a double layer of wrapping, which enhances the packaging protection of the heater.

[0031] Among them, the bottom end of the upper support foam 3 is fixedly connected to a foam insert 3011. The foam insert 3011 has a rectangular frame structure. The foam insert 3011 matches the positioning slot 2013 opened at the top of the lower support foam 2. The foam insert 3011 and the positioning slot 2013 together form a sealing structure. By opening an upper mold cavity 3012 at the bottom end of the upper support foam 3 with the same structure as the lower mold cavity 2014, the upper mold cavity 3012 can be adapted to the lower mold cavity 2014, and wrap the heater from the top and bottom sides, limiting the space for the heater to shake in the packaging, better adapting to the shape of the heater, and improving the protection effect on vulnerable parts such as the heater's air outlet and control panel.

[0032] Working principle: The operator first places the heater to be packaged precisely inside the lower mold cavity 2014 opened at the top of the lower support foam 2. Since the lower mold cavity 2014 is a groove structure that adapts to the shape of the heater, it can directly form a lateral limit on the heater, preventing the heater from shifting on the surface of the lower support foam 2, thus laying a stable foundation for the subsequent assembly process. The operator holds the upper support foam 3 and aligns the rectangular frame structure foam block 3011 fixedly connected to its bottom with the positioning slot 2013 opened at the top of the lower support foam 2. Then, the operator slowly inserts the foam block 3011 into the positioning slot 2013. At this time, the upper support foam 3 and the lower support foam 2 are precisely connected. At the same time, the upper mold cavity 3012 opened at the bottom of the upper support foam 3 (which has the same structure as the lower mold cavity 2014) covers the top of the heater and forms a closed enclosing space together with the lower mold cavity 2014. This forms a longitudinal limit on the heater from the top and bottom, further strengthening the fixing effect of the heater. The operator will embed the assembled lower support foam 2 and upper support foam 3 into the packaging box 1. During this process, the foam structure anti-collision posts 201, which are fixedly connected to the four outer corners of the lower support foam 2 and upper support foam 3, will form a buffer gap with the inner wall of the packaging box 1, which can pre-bear the impact force that may be applied from the outside. At the same time, the X-shaped reinforcing foam 301, which is fixedly connected to the bottom surface of the lower support foam 2 and the top surface of the upper support foam 3, can enhance the structural strength of the foam used for the upper and lower supports, prevent the assembly from deforming due to force during the embedding process, and ensure the integrity of the foam structure. When it is necessary to separate the foam from the packaging box 1, since the insertion slots 2011 on the left and right sides of the upper support foam 3 are in a continuous state with the insertion slots 2011 on the left and right sides of the lower support foam 2, the operator can put his hand into the continuous insertion slot 2011, and then grasp the grip groove 2012 designed for the hand in the insertion slot 2011 and apply a uniform pulling force away from the packaging box 1; with the help of the stable force application point provided by the grip groove 2012, the combination of the lower support foam 2 and the upper support foam 3 can be easily removed from the packaging box 1 without causing damage to the foam structure, and finally the foam and the packaging box 1 are completely separated.
