Abstract
The utility model discloses a heat preservation paper box layer structure and a paper box thereof, comprising a first base layer and a second base layer, wherein a reinforcing layer is bonded between the first base layer and the second base layer; and an insulation layer is arranged in the enhancement layer. Through adopting the design that enhancement layer and heat preservation combined together, can increase the heat preservation effect when increasing carton structural strength to adopt the mode of filling the chamber to place the heat preservation, can protect insulation material, avoid insulation material's damage, improve the life of carton.
Description
Technical Field
The utility model relates to the technical field of packaging cartons, in particular to a heat preservation carton layer structure and a carton thereof.
Background
The paper box is the most widely used packaging product, and has various specifications and models, such as corrugated paper boxes, single-layer paper boxes and the like according to different materials. The paper box is commonly used with three layers and five layers, seven layers are less, each layer is divided into lining paper, corrugated paper, core paper and face paper, the lining paper and the face paper are provided with tea board paper and kraft paper, the corrugated paper for the core paper has different colors and handfeel, and the paper (color and handfeel) produced by different manufacturers is also different.
The corrugated paper box used at present has almost no heat preservation effect, articles stored inside are difficult to preserve temperature, and the temperature inside is fast to dissipate.
Disclosure of Invention
The utility model aims to solve the problem that the existing paper box does not have a heat preservation function, and provides a heat preservation paper box layer structure and a paper box thereof.
The heat preservation carton layer structure comprises a first base layer and a second base layer, wherein a reinforcing layer is bonded between the first base layer and the second base layer; and an insulation layer is arranged in the enhancement layer.
Further, the enhancement layer sets up to the bar structure, the inside filling chamber that is provided with of enhancement layer, the heat preservation fills and sets up in filling chamber.
Further, the filling cavity is arranged in a rectangular structure.
Further, the reinforcing layer is made of light plastic; the heat preservation layer is filled by foam.
Furthermore, a protective layer is also smeared on the surface of the second base layer.
A heat preservation paper box is provided with the paper box layer structure.
The beneficial effects of the utility model are as follows:
1. through setting up the heat preservation between first basic unit and second basic unit, can realize the heat preservation function of carton.
2. Through adopting the design that enhancement layer and heat preservation combined together, can increase the heat preservation effect when increasing carton structural strength to adopt the mode of filling the chamber to place the heat preservation, can protect insulation material, avoid insulation material's damage, improve the life of carton.
Drawings
FIG. 1 is a schematic cross-sectional view of the present carton aspect;
in the figure, 1-first base layer, 2-reinforcing layer, 21-filling cavity, 3-heat preservation layer, 4-second base layer and 5-protective layer.
Detailed Description
Other advantages and effects of the present utility model will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present utility model with reference to specific examples. The utility model may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present utility model. It should be noted that the following embodiments and features in the embodiments may be combined with each other without conflict.
It should be noted that the illustrations provided in the following embodiments merely illustrate the basic concept of the present utility model by way of illustration, and only the components related to the present utility model are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complicated.
Example 1
As shown in fig. 1, the heat insulation carton layer structure comprises a first base layer 1 and a second base layer 4, specifically, the first base layer 1 and the second base layer 4 are made of flat paper materials, wherein the first base layer 1 serves as an outer layer of the carton, and the second base layer 4 serves as an inner layer of the carton.
A reinforcing layer 2 is arranged between the first base layer 1 and the second base layer 4 in a bonding way; the enhancement layer 2 is arranged to be in a strip-shaped structure, and specifically, during processing, strong glue is uniformly coated on the inner side surface of the first base layer 1 and the outer side surface of the second base layer 4, and the enhancement layer 2 is attached between the inner side surface of the first base layer 1 and the outer side surface of the second base layer 4.
In order to increase the structural strength of the reinforcing layer 2, the reinforcing layer 2 is a lightweight plastic.
The reinforcing layer 2 is internally provided with a filling cavity 21, and the filling cavity 21 is arranged in a rectangular structure. The design of rectangular structure can realize the I shape support of enhancement layer 2, can reduce the use amount of light plastics under the circumstances of guaranteeing structural strength.
And an insulation layer 3 is arranged in the reinforcing layer 2. Specifically, the insulating layer 3 is composed of a foam filling, and the foam filling is disposed in the filling cavity 21 when in use.
In order to further increase the heat insulation performance of the carton, a protective layer 5 is also smeared on the surface of the second base layer 4. Preferably, the protective layer 5 is provided as an aluminum film.
Through the design that adopts enhancement layer 2 and heat preservation 3 to combine together, can increase the heat preservation effect when increasing carton structural strength to adopt the mode of filling cavity 21 to place heat preservation 3, can protect heat preservation, avoid heat preservation's damage, improve the life of carton.
Example 2
A heat preservation paper box is provided with the paper box layer structure.
The foregoing examples merely illustrate specific embodiments of the utility model, which are described in greater detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
