Description
Technical field
The utility model relates to food container technical fields, and in particular to a kind of disposable paper food container.
Background technique
When rhythm of life is increasingly accelerated, people are inclined to simple life more asking.From traditional " eat as day " to today
" busy to cook ".It cooks and constantly upgrades with the contradiction of work strain, the booming and line for creating take-away food delivery business is online
Under (020) on the net make a reservation the mode of ordering takeaway.Now more outer real quotient are taking out cell phone client using light mode, as Meituan takes out,
Baidu takes out, and Logistics Project is done inside molality formula light: making into wood reduction, profit improvement and survival rate and increases.According to 2016
Year, first half of the year DCCI Internet data center showed, user considers to take out in the factor of platform with the safety and quality of food delivery food
Positioned at forefront (85% is shown as the place for needing to pay attention to).Therefore it " takes out heat " and becomes barrier.Its shock resistance of existing takeout box compared with
Difference, meanwhile, during taking out dispatching, since the equal many factors of weather or traffic influence, lead to sending for a take-away
Generally all it is higher than half an hour up to the time, so that taking out after being completed from businessman, during being sent in user hand, takes out
Because the heat insulating ability of takeout box is poor, take-away turns cold, and has lost best flavor, meanwhile, existing takeout box multiselect plastics
It is made, non-degradable, user can abandon takeout box after dining, cause environmental pollution, also, existing takeout box
Intelligence degree is low, lacks device of tracing to the source accordingly.
Utility model content
In view of the drawbacks of the prior art, the utility model provides a kind of disposable paper food container, existing for solving
Some takeout box heat insulating abilities are poor, cannot independently degrade, and the feature of environmental protection is poor, can not track the problem of tracing to the source.
In order to achieve the above objectives, the utility model provides a kind of disposable paper food container, including degradable
First box body and the second box body；
The upper end of first box body and the second box body is equipped with opening, and the first box body can be plugged in the second box body, the
The first heat preservation film layer is bonded on the inner sidewall of one box body.
In the above-mentioned technical solutions, the present invention can also be improved as follows.
Preferred technical solution, additional technical feature are: being bonded with the second guarantor on the lateral wall of second box body
Warm film layer.
Preferred technical solution, additional technical feature are: being equipped with side by side in the inner bottom wall of second box body several
Convex stud.
Preferred technical solution, additional technical feature are: the convex stud is two, single convex stud and the first box
The exterior bottom wall of body is bonded by viscose, and the first cavity is enclosed between single convex stud and second box body, and two convex vertical
The second cavity is enclosed between muscle and the second box body.
Preferred technical solution, additional technical feature are: first box body is in pyramidal, the opening of the first box body
Area is greater than the bottom area of the first box body, and the open outer side of the first box body, which encloses, is equipped with the first surrounding edge.
Preferred technical solution, additional technical feature are: second box body is in pyramidal, the opening of the second box body
Area is greater than the bottom area of the second box body, and the opening inner side of the second box body, which encloses, is equipped with the second surrounding edge, first surrounding edge with
Second surrounding edge mutually bonds.
Preferred technical solution, additional technical feature are: the first heat preservation film layer and the second heat preservation film layer are selected
Use polylactic acid membrane.
Preferred technical solution, additional technical feature are: the thickness of the first heat preservation film layer and the second heat preservation film layer
Degree is 0.01-0.02mm.
Preferred technical solution, additional technical feature are: heat preservation is equipped between first box body and the second box body
Layer.
Preferred technical solution, additional technical feature are: being sticked between first box body and the second box body has electricity
Subtab.
The utility model has the following beneficial effects:
The first, for from the appearance, the wall thickness of the first box body and the second box body in the utility model food container is respectively only
In 1.0-1.5mm, the probability of the surface indentation of box wall, shrinkage cavity and the mass defects such as sandwich can be greatly reduced in process of production,
It is bonded with film layer made of the polylactic acid of plant refinement on the inside of first box body of the utility model and on the outside of the second box body simultaneously,
Therefore the utility model food container is integrally inside and outside two-sided with gloss and smooth；
The second, in terms of thermal insulation property promotion, because being glued on the inside of first box body of the utility model and on the outside of the second box body
Film layer made of the polylactic acid of plant refinement is had, to enable the overall surface of entire utility model there is gloss therefore to promote guarantor
Warm nature energy should be based on the phenomenon that radiating heat propagation, and the easy reflected radiation heat of the smooth object in surface is also not easy discharging radiation heat, therefore
Film layer is coated in the interior outside of whole container can be with reflected radiation heat, while heat can not be spread out of with method of radiating in outside container, in addition,
Insulating layer is embedded in as filling materials, this cooperation can be reduced heat during hot food is placed on container to conduct and convection type
It spreads out of outside container, the mutual cooperation of film layer and insulating layer, which is used, enhances the utility model thermal insulation property；
Third, about customer experience management, the utility model food container combination Internet of Things enters 020 new model, penetrates
The mobile phone of electronic tag and customer with NFC function being attached in utility model food container carries out data interchange, related customer
It is expected that the information read and write with experience, thus promote the participation of Customer Experience and therefrom reduce the desired drop of customer,
Finally realize the promotion to customer satisfaction.
