A ceramic packaging carton with reinforced corner sleeves

Abstract

This utility model relates to the field of ceramic packaging cartons, specifically disclosing a ceramic packaging carton with corner reinforcement sleeves. The carton includes a main body, with a reinforcing protective mechanism on its outer side. This mechanism includes an outer frame, and four corners of the lower inner wall of the outer frame are each provided with a first reinforcing sleeve that fits against the outer wall of the main body. A cover is provided on the top of the outer frame. The first and second reinforcing sleeves work together to form a fully enclosed reinforcing structure for the upper and lower corners of the main body, providing targeted reinforcement to the corners. This effectively solves the problems of tearing, deformation, and structural collapse caused by stress concentration at the corners of traditional cartons, preventing ceramic products from losing protection. The sponge pad absorbs the vibration energy generated by transport bumps through elastic cushioning, effectively preventing ceramic products from rolling, colliding, or shifting within the main body of the carton, thereby improving the transport safety of ceramic products and reducing the breakage rate.

Description

Technical Field

[0001] This utility model relates to the field of ceramic packaging cartons, and specifically discloses a ceramic packaging carton with corner reinforcement sleeves. Background Technology

[0002] Ceramics are materials made from inorganic non-metallic raw materials such as clay, quartz, and feldspar through high-temperature sintering. They possess characteristics such as high-temperature resistance, corrosion resistance, high hardness, and excellent surface finish, and are widely used in daily utensils, artistic decorations, and industrial components. Cylindrical ceramic products, such as ceramic bottles, storage jars, and industrial ceramic tubes, are particularly common due to their simple and practical design and high space utilization. However, while these products are hard, they lack toughness and are easily damaged during transportation due to collisions and compression, thus requiring the protection of packaging cartons. As the primary carrier for transporting ceramic products, the structural rationality of the packaging cartons directly affects the safety of the ceramic products.

[0003] Currently, existing ceramic packaging cartons generally suffer from two major technical defects: Firstly, as a typical hexahedral structure, the corners of a carton are the intersection points of its edges. Under external forces (such as handling collisions and stacking pressure), significant stress concentration occurs at the corners, meaning the force per unit area is much greater than in other parts. Because existing cartons often lack targeted reinforcement at the corners, they are highly susceptible to tearing and deformation during transportation due to stress concentration, even leading to the collapse of the entire carton structure and thus losing its protective function for the internal ceramic products. Secondly, when packaging cylindrical ceramic products, multiple products usually need to be arranged neatly inside the carton, separated by partitions. However, existing cartons lack effective internal protective structures, making it difficult to prevent ceramic products from bumping into each other during transportation, especially thin-walled cylindrical products, which have a higher breakage rate due to collisions.

[0004] Therefore, a ceramic packaging carton with reinforced corner sleeves is needed to solve the above problems. Utility Model Content

[0005] This utility model proposes a ceramic packaging carton with corner reinforcement sleeves, which specifically strengthens the corners of the packaging carton body, effectively solving the problems of tearing, deformation and structural collapse caused by stress concentration at the corners of traditional cartons, and preventing ceramic products from losing protection; at the same time, it improves the transportation safety of ceramic products and reduces the breakage rate.

[0006] This utility model is implemented as follows: a ceramic packaging carton with corner reinforcing sleeves includes a packaging carton body. A reinforcing protective mechanism is provided on the outer side of the packaging carton body. The reinforcing protective mechanism includes an outer frame. At the four corners of the lower side of the inner wall of the outer frame, a first reinforcing sleeve is provided that fits against the outer wall of the packaging carton body. A cover is provided on the top of the outer frame. At the four corners of the upper side of the inner wall of the cover, a second reinforcing sleeve is provided that fits against the outer wall of the packaging carton body.

[0007] The interior of the packaging carton body is provided with multiple sponge pads stacked vertically, and the upper end of each sponge pad has multiple evenly distributed receiving cavities.

[0008] As a preferred embodiment of the ceramic packaging carton with corner reinforcement sleeves of this utility model, both the outer wall of the first reinforcement sleeve and the outer wall of the cover are provided with tear-resistant layers, and the two tear-resistant layers are fixed together by adhesive tape.

[0009] As a preferred embodiment of the ceramic packaging carton with corner reinforcement sleeves according to this utility model, the four first reinforcement sleeves and the four second reinforcement sleeves are all made of rigid plastic.

[0010] As a preferred embodiment of the ceramic packaging carton with corner reinforcement sleeves of this utility model, the bottom end of the outer frame wall is fixedly connected to a support plate that fits against the lower end of the packaging carton body, and the top end of the inner wall of the sleeve is fixedly connected to a limiting plate that fits against the upper end of the uppermost sponge pad.

[0011] As a preferred embodiment of the ceramic packaging carton with corner reinforcing sleeves of this utility model, the four first reinforcing sleeves are all fixed to the inner wall of the outer frame by hot melt adhesive, and the four second reinforcing sleeves are all fixed to the inner wall of the cover by hot melt adhesive.

[0012] As a preferred embodiment of the ceramic packaging carton with corner reinforcement sleeves of this utility model, the carton body, outer frame, and cover are all made of corrugated paper.

[0013] The beneficial effects of this utility model are:

[0014] 1. An outer frame is installed on the outside of the packaging carton. The first reinforcing sleeves at the four corners of the lower inner wall of the frame are attached to the four corners of the outer wall of the carton. A cover is fitted onto the outer wall of the frame, and the second reinforcing sleeves at the four corners of the upper inner wall of the cover are attached to the four corners of the top of the carton. The first and second reinforcing sleeves work together to form a fully enclosed reinforcement structure for the top and bottom corners of the packaging carton, completely covering all eight corners. This design provides targeted reinforcement to the corners of the packaging carton, effectively solving the problems of tearing, deformation, and structural collapse caused by stress concentration at the corners of traditional cartons, and preventing ceramic products from losing their protection.

[0015] 2. The packaging carton contains multiple layers of custom-made sponge pads, whose cavities are tightly embedded in the ceramic products, completely separating them and preventing them from contacting each other. The sponge pads absorb the vibration energy generated by transport bumps through elastic cushioning, and work with internal limiting and support plates to limit their vertical movement. This design effectively prevents the ceramic products from rolling, colliding, or shifting within the packaging carton, thereby improving the safety of transporting the ceramic products and reducing the breakage rate.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-4 A ceramic packaging carton with corner reinforcement sleeves includes a packaging carton body 1. A reinforcement protection mechanism is provided on the outside of the packaging carton body 1. The reinforcement protection mechanism includes an outer frame 2. A first reinforcement sleeve 4 that fits against the outer wall of the outer carton body 1 is provided at the four corners of the lower side of the inner wall of the outer frame 2. A cover 3 is provided on the top of the outer frame 2. A second reinforcement sleeve 5 that fits against the outer wall of the packaging carton body 1 is provided at the four corners of the upper side of the inner wall of the cover 3.

[0024] The interior of the packaging carton body 1 is provided with multiple sponge pads 10 stacked vertically, and the upper end of each sponge pad 10 is provided with multiple evenly distributed receiving cavities 11.

[0025] In this embodiment: Before the ceramic product packaging operation, the outer frame 2 is first fitted onto the outside of the packaging carton body 1, so that the first reinforcing sleeve 4 at the four corners of the lower side of the inner wall of the outer frame 2 fits into the four corners of the outer wall of the packaging carton body 1, forming the initial corner support structure.

[0026] After the outer frame 2 is installed, a sponge pad 10 is placed inside the packaging carton body 1. The receiving cavity 11 opened at the upper end of the sponge pad 10 is customized according to the size, depth and shape of the ceramic product to ensure that the ceramic product can be tightly embedded in the receiving cavity 11. Then, the ceramic product is loaded into the receiving cavity 11 of the bottom sponge pad 10. Subsequently, the sponge pads 10 are stacked layer by layer. The receiving cavity 11 of each layer of sponge pad 10 is placed in a corresponding ceramic product, thereby completely separating the ceramic products and preventing them from contacting each other.

[0027] After loading, the upper end of the top layer of sponge pad 10 is coplanar with the upper end of the packaging carton body 1. Then, the cover 3 is put on the outer wall of the outer frame 2, so that the second reinforcing sleeve 5 at the four corners of the inner wall of the cover 3 fits with the outer wall of the top four corners of the packaging carton body 1, forming a fully enclosed reinforcement structure for the upper and lower corners of the packaging carton body 1. The second reinforcing sleeve 5 and the first reinforcing sleeve 4 work together to completely wrap the eight corners of the packaging carton body 1, effectively coping with the stress concentration caused by external loads such as handling collisions and stacking pressure.

[0028] Subsequently, the outer frame 2 and the cover 3 are glued and fixed to complete the packaging. During transportation, the first reinforcing sleeve 4 and the second reinforcing sleeve 5 serve as rigid support structures at the corners, providing targeted reinforcement to the corners of the packaging carton body 1. This effectively solves the problems of tearing, deformation, and structural collapse caused by stress concentration at the corners of traditional cartons, and prevents ceramic products from losing their protection.

[0029] The cavity 11 of the sponge pad 10 inside the packaging carton body 1 absorbs the vibration energy generated by transportation bumps through elastic buffering. Together with the upper and lower limits of the limiting plate 7 and the support plate 6, it prevents ceramic products from rolling, colliding or shifting inside the packaging carton body 1, thereby improving the transportation safety of ceramic products and reducing the breakage rate.

[0030] As a technical optimization of this utility model, both the outer wall of the first reinforcing sleeve 4 and the outer wall of the cover 3 are provided with tear-resistant layers 8, and the two tear-resistant layers 8 are fixed together by adhesive tape 9.

[0031] In this embodiment: the tear-resistant layer 8 of the outer wall of the first reinforcing sleeve 4 and the outer wall of the cover 3 is made of high-strength paper material, which can withstand the tensile force when the tape 9 is pasted. The tear-resistant layer 8 serves as an intermediate transition layer to prevent the tape 9 from directly adhering to the surface of the corrugated paper frame 2 and the cover 3, and to prevent the first reinforcing sleeve 4 and the cover 3 from being torn when the tape 9 is removed, thereby realizing the reuse of the outer frame 2 and the cover 3.

[0032] As a technical optimization of this utility model, the four first reinforcing sleeves 4 and the four second reinforcing sleeves 5 are all made of hard plastic.

[0033] In this embodiment, the four first reinforcing sleeves 4 and the four second reinforcing sleeves 5 are all made of hard plastic, thereby improving the reliability of corner protection.

[0034] As a technical optimization of this utility model, the bottom of the outer wall of the outer frame 2 is fixedly connected to a support plate 6 that fits against the lower end of the packaging carton body 1, and the top of the inner wall of the cover 3 is fixedly connected to a limiting plate 7 that fits against the upper end of the uppermost sponge pad 10.

[0035] In this embodiment: the lower end of the packaging carton body 1 is supported by the support plate 6 to prevent the bottom from collapsing, and the limiting plate 7 restricts the vertical displacement of the sponge pad 10, thereby fixing the top position of the uppermost ceramic product and preventing the ceramic product from jumping upward due to vertical impact during transportation.

[0036] As a technical optimization of this utility model, the four first reinforcing sleeves 4 are all fixed to the inner wall of the outer frame 2 by hot melt adhesive, and the four second reinforcing sleeves 5 are all fixed to the inner wall of the cover 3 by hot melt adhesive.

[0037] In this embodiment: Since the four first reinforcing sleeves 4 are all fixed to the inner wall of the outer frame 2 by hot melt adhesive, and the four first reinforcing sleeves 4 are all fixed to the inner wall of the cover 3 by hot melt adhesive, the four first reinforcing sleeves 4 and the four second reinforcing sleeves 5 are fixed.

[0038] As a technical optimization of this utility model, the packaging carton body 1, the outer frame 2, and the cover 3 are all made of corrugated paper.

[0039] In this embodiment: the packaging carton body 1, the outer frame 2 and the cover 3 are all made of corrugated paper. Corrugated paper, as the main structure of the packaging, is lightweight, low-cost and has a certain degree of cushioning.

[0040] The working principle and usage process of this utility model are as follows: Before packaging ceramic products, the outer frame 2 is first fitted onto the outside of the packaging carton body 1, so that the first reinforcing sleeve 4 at the four corners of the lower side of the inner wall of the outer frame 2 is attached to the four corners of the outer wall of the packaging carton body 1. The first reinforcing sleeve 4 is pre-fixed to the inner wall of the outer frame 2 by hot melt adhesive, and its rigid plastic material forms the initial corner support structure. The support plate 6 at the bottom of the outer frame 2 is simultaneously and tightly attached to the lower end face of the packaging carton body 1, providing bottom horizontal support for the packaging carton body 1 and preventing the lower end of the packaging carton body 1 from collapsing.

[0041] After the outer frame 2 is installed, a sponge pad 10 is placed inside the packaging carton body 1. The receiving cavity 11 opened at the upper end of the sponge pad 10 is customized according to the size, depth and shape of the ceramic product to ensure that the ceramic product can be tightly embedded in the receiving cavity 11. Then, the ceramic product is loaded into the receiving cavity 11 of the bottom sponge pad 10. Subsequently, the sponge pads 10 are stacked layer by layer. The receiving cavity 11 of each layer of sponge pad 10 is placed in a corresponding ceramic product, thereby completely separating the ceramic products and preventing them from contacting each other.

[0042] After loading, the upper end of the top layer of sponge pad 10 is coplanar with the upper end of the packaging carton body 1. Then, the cover 3 is put on the outer wall of the outer frame 2, so that the second reinforcing sleeve 5 at the four corners of the inner wall of the cover 3 fits with the outer wall of the top four corners of the packaging carton body 1, forming a fully enclosed reinforcement structure for the upper and lower corners of the packaging carton body 1. The second reinforcing sleeve 5 is also fixed to the inner wall of the cover 3 by hot melt adhesive, and works together with the first reinforcing sleeve 4 at the bottom to completely wrap the eight corners of the packaging carton body 1, effectively coping with stress concentration caused by external loads such as handling collisions and stacking pressure.

[0043] Subsequently, adhesive tape 9 is attached to the two tear-resistant layers 8 to fix the outer frame 2 and the cover 3, thus completing the packaging. The tear-resistant layer 8 is made of high-strength material and can withstand the tensile force when the tape 9 is attached and torn, avoiding direct tearing damage to the outer frame 2 and the cover 3, thereby enabling the reuse of the outer frame 2 and the cover 3. During transportation, the first reinforcing sleeve 4 and the second reinforcing sleeve 5 serve as rigid support structures at the corners, providing targeted reinforcement to the corners of the packaging carton body 1, effectively solving the problems of tearing, deformation and structural collapse caused by stress concentration at the corners of traditional cartons, and preventing ceramic products from losing protection.

[0044] The cavity 11 of the sponge pad 10 inside the packaging carton body 1 absorbs the vibration energy generated by transportation bumps through elastic buffering. Together with the upper and lower limits of the limiting plate 7 and the support plate 6, it prevents ceramic products from rolling, colliding or shifting inside the packaging carton body 1, thereby improving the transportation safety of ceramic products and reducing the breakage rate.
