Abstract
An embodiment of the utility model discloses a fresh-keeping carton which comprises a carton and a heat-insulation layer. The heat-insulation layer is arranged in the carton and comprises a first clamp plate, a second clamp plate and an expanded plastic layer; the expanded plastic layer is arranged between the first clamp plate and the second clamp plate and contains bubbles, and a ratio of the total volume of the bubbles to the volume of the expanded plastic layer ranges from 1:10 to 7:10. The fresh-keeping carbon in the embodiment of the utility model has the advantages that external heat can be prevented from being transferred into the carton, and accordingly the temperature of the inside of the carbon is constant.
Description
Technical field
The utility model relates to a kind of carton, particularly a kind of fresh-keeping corrugated box.
Background technology
Traditional carton is generally used for placing articles.But the effect of heat insulation of traditional carton is poor, when the temperature of external environment condition can not be born high temperature compared with thing high and that place in carton, because traditional carton can not completely cut off the high temperature of external environment condition, therefore the article of placing in traditional carton likely damage.
Therefore, be necessary to propose a kind of new technical scheme, to solve the problems of the technologies described above.
Utility model content
The purpose of this utility model is to provide a kind of fresh-keeping corrugated box, and its heat that can prevent carton outside enters in carton, thereby makes the temperature constant in carton.
For addressing the above problem, the technical scheme of the utility model embodiment is as follows:
A fresh-keeping corrugated box, comprising: casing; Thermal insulation layer, described thermal insulation layer is arranged in described casing, and described thermal insulation layer comprises: the first clamping plate; The second clamping plate; And foamed plastic layer; Wherein, described foamed plastic layer is arranged between described the first clamping plate and described the second clamping plate, in described foamed plastic layer, contains bubble, in the scope of the ratio of the volume of the cumulative volume of described bubble and described foamed plastic layer in 1:10 to 7:10.
In above-mentioned fresh-keeping corrugated box, described thermal insulation layer is fixed in described casing by viscose glue.
In above-mentioned fresh-keeping corrugated box, described the first clamping plate are towards the inwall of described casing, and described the second clamping plate are the inwall of described casing dorsad, and described the first clamping plate are fixed in described casing by described viscose glue.
In above-mentioned fresh-keeping corrugated box, on the surface of described the first clamping plate, be provided with array of depressions, described array of depressions includes a plurality of depressions.
In above-mentioned fresh-keeping corrugated box, the extreme depth of described depression is in the scope of 1 millimeter to 8 millimeters.
In above-mentioned fresh-keeping corrugated box, the radius of the maximum circumscribing circle of described depression is in the scope of 2 millimeters to 25 millimeters.
In above-mentioned fresh-keeping corrugated box, the radius of the maximum circumscribing circle of described depression is in the scope of 5 millimeters to 15 millimeters.
In above-mentioned fresh-keeping corrugated box, in the scope of the ratio of the volume of the cumulative volume of described bubble and described foamed plastic layer in 3:10 to 1:2.
In above-mentioned fresh-keeping corrugated box, described in each in the scope of the volume of bubble in 0.05 cm3 to 0.3 cm3.
In above-mentioned fresh-keeping corrugated box, described foamed plastic layer is fixed together by glue and described the first clamping plate and described the second clamping plate.
Relative prior art, fresh-keeping corrugated box of the present utility model can prevent that the heat of carton outside from entering in carton, thereby makes the temperature constant in carton.
For foregoing of the present utility model can be become apparent, preferred embodiment cited below particularly, and coordinate appended graphicly, be described in detail below:
Accompanying drawing explanation
Fig. 1 is the schematic diagram of fresh-keeping corrugated box of the present utility model.。
The specific embodiment
The explanation of following embodiment is graphic with reference to what add, can be in order to the specific embodiment of implementing in order to illustration the utility model.
With reference to figure 1, the schematic diagram that Fig. 1 is fresh-keeping corrugated box of the present utility model.
The fresh-keeping corrugated box of the present embodiment comprises: casing 101 and thermal insulation layer 102, described thermal insulation layer 102 is arranged in described casing 101, and described thermal insulation layer 102 comprises the first clamping plate (not shown), the second clamping plate (not shown) and foamed plastic layer (not shown); Wherein, described foamed plastic layer is arranged between described the first clamping plate and described the second clamping plate, in described foamed plastic layer, contains bubble, in the scope of the ratio of the volume of the cumulative volume of described bubble and described foamed plastic layer in 1:10 to 7:10.
Fresh-keeping corrugated box of the present utility model can prevent that the heat of carton outside from entering in carton, thereby makes the temperature constant in carton, is conducive to keep the freshness of the food in case.
In above-mentioned fresh-keeping corrugated box, described thermal insulation layer 102 is fixed in described casing 101 by viscose glue, described the first clamping plate are towards the inwall of described casing 101, and described the second clamping plate are the inwall of described casing 101 dorsad, and described the first clamping plate are fixed in described casing 101 by described viscose glue.Described foamed plastic layer is fixed together by glue and described the first clamping plate and described the second clamping plate.
On the surface of described the first clamping plate, be provided with array of depressions, described array of depressions includes a plurality of depressions, wherein, the extreme depth of described depression is in the scope of 1 millimeter to 8 millimeters, the radius of the maximum circumscribing circle of described depression is in the scope of 2 millimeters to 25 millimeters, preferably, the radius of the maximum circumscribing circle of described depression is in the scope of 5 millimeters to 15 millimeters.By on described the first clamping plate, array of depressions being set, can be so that described thermal insulation layer and described casing be firmly fixed together.
In the scope of the ratio of the volume of the cumulative volume of described bubble and described foamed plastic layer in 3:10 to 1:2, wherein, described in each in the scope of the volume of bubble in 0.05 cm3 to 0.3 cm3.Like this, be conducive to make heat-insulating property better.
In sum; although the utility model discloses as above with preferred embodiment; but above preferred embodiment is not in order to limit the utility model; those of ordinary skill in the art; within not departing from spirit and scope of the present utility model; all can do various changes and retouching, the scope that therefore protection domain of the present utility model defines with claim is as the criterion.
