Description
Technical field
The present invention relates to the technical field of daily necessity, more specifically to a kind of papery disposable lunch-box.
Background technique
In life, fast food lunch-box generally refers to disposable lunch box.In the market, the feelings not found in user
Under condition, there are many cutlery boxs have be utilized again or food delivery road in deliberately opened the phenomenon that, such dining box structure just loses
The problems such as having gone disposable and safe meaning, there is easy leakage and having poisoned, causes security risk.Such as apply
Number: the utility model of 201720127809.X discloses a kind of cutlery box, including box body and box cover, and the box body and box cover are by food
Grade plastics are made, and the upper end of the box body is equipped with the button tongue to extend out, and the edge of the box cover is equipped with to be adapted with button tongue
Catching groove, catching groove and button tongue are irreversible primary and secondary back-off structure, and box cover is equipped with recessed kerve, kerve and catching groove it
Between, the box cover is equipped with a circle V-shaped notch of the opening being convenient for.This be our company application can only disposable lunch box
Patent, material are plastics, the papery that can be degraded can only first use mess-tin difficulty it is very big.For another example application number:
201310224765.9 authorization patent of invention, disclose a kind of manufacturing method of novel degradable non-toxic disposable bowl for snack,
It joined following process on the basis of modern disposable paper bowl for snack manufacturing process: nano-titanium dioxide being added in paper pulp
And it is uniformly mixed；One layer of chitosan-gelatin composite membrane of even spread inside bowl for snack, while plasticizer glycerol and tristearin is added
The mixture of acid and palmitic acid is put into drying box heating, is dried at room temperature for forming a film.There is no mistake disposably, but can only drop
Solution, it cannot be guaranteed that the safety of food.The present invention seeks to provide a cutlery box that can guarantee food safety and can degrade again
Product.
Summary of the invention
Emphasis of the present invention solves the problems, such as that disposable lunch-box cannot be guaranteed food safety in the prior art, provides a kind of papery
The disposable snack box that can be degraded is a kind of practical product of upgrading.
In order to solve existing above-mentioned technical problem, the present invention takes following technical proposals: disposable lunch-box, including papery
Box body and lid, which is characterized in that the top of the box body is equipped with cylindrical structure, the end of the cylindrical structure be crimping or
Flanging or straight flange, the inner wall of the cylindrical structure are equipped with cricoid protrusion or groove, the lower part of the box body be cylinder body or
The port of vertebra staving, the cylinder body or vertebra staving is crimping or flanging or straight flange, the top and the bottom overlap joint of the box body；Institute
It states and is equipped with cylinder on the outside of lid, the outside of the cylinder is equipped with and the matched annular recess of box body cylindrical structure inner wall
Or protrusion, the lid are equipped with opening device.
The maximum feature of this papery disposable snack box is: lid is to fill in box body upper interior, box body top
Protrusion or groove on the inside of cylindrical structure and on the outside of lid cylinder cooperate, the purpose is to prevent lid from opening easily, when
So, also certainly openable using sucker on lid since this interference that is fastened and connected is not too large, but do not destroying lid
Body or box body, it is difficult for manually opening, therefore has anti-theft function.Lid is fastened on tray interior, without impetus,
Lid is opened, the opening device that can only just lid is used to be equipped with, destroying lid could open, and may insure in cutlery box in this way
Food first switches on, because being the cutlery box of papery, and can degrade.Box body using upper and lower two parts overlapped structure,
Main purpose is to be equipped with step in junction, is positioned convenient for lid；Second, the rigidity of box body is improved, the mistake with lid is conducive to
It is full of connection, prevents lid from being extruded easily.
Preferably, the lid is that two ply board structure is fixedly connected with cylinder, lower layer paperboard is equipped with air hole, on
Layer paperboard is equipped with U-shaped or annular breaks indentation.What user's button opened upper layer cardboard breaks indentation, so that it may pull open lid use
Meal.
Preferably, the lid is two ply board structure, lower layer paperboard is free state, and lower layer paperboard is equipped with ventilative
Hole, upper layer cardboard are fixedly connected with cylinder, and upper layer cardboard is equipped with U-shaped or annular breaks indentation.User's button opens upper paper
Plate breaks indentation, so that it may pull open lid dining.
Preferably, the U-shaped that lid upper layer cardboard is equipped with breaks the arc structure that indentation is semicircle or more.User
What button opened upper layer cardboard breaks indentation, and taking out lower layer paperboard can directly eat.
Preferably, the box body top, which is divided under the cylindrical structure and box body of two inner beads, partially has outer crimping
Staving dislocation lap joint is bored, forms groove between two crimpings of box body；The upper end of the lid cylinder is equipped with outer crimping knot
Structure is caught between lid crimping as protrusion and forms in groove.This is relatively good one of the structure of rigidity of the present invention, on cutlery box
There are four crimpings to form altogether in portion.
Preferably, the box body top is divided into the cylindrical structure of inside and outside each one two-fold side composition, the cylinder knot
The cone staving dislocation lap joint of outer crimping is partially had under the inner bead and box body of structure, is equipped with groove between two crimpings of box body；
The upper end of the lid cylinder is equipped with outer bead structure, is caught in the groove of lid as protrusion.
Preferably, the box body top is divided into the cylindrical structure of the composition of a flanging and a crimping, the cylinder
Partially with the cone staving dislocation lap joint of outer crimping or flanging under the crimping and box body of structure, the flanging on cylindrical structure top with
Box body lower part forms groove between bundling side；The top of the lid cylinder is inside bead structure, the cylinder
Lower end be equipped with outside folded edges, the folded edges of the cylinder be caught between lid crimping as protrusion form it is recessed
In slot.Cutlery box top shares 2-3 crimping and 3-2 flanging forms, and two folded edges of box body and lid are interlocked.
Preferably, the crimping of the box body and the flanging of lid, the end of at least one convolution is to stick up structure outside.This
The outer of sample sticks up structure just equivalent and hangnail, so that box body and lid fastening are more reliable.
Preferably, the box body top is divided into the cylindrical structure of a crimping or flanging and straight flange composition, it is described
The flanging cylinder body dislocation lap joint of part under the straight flange and box body of box body cylindrical structure, the flanging on cylindrical structure top or crimping
Lower section is equipped with groove or protrusion, and the top of the lid cylinder is inside bead structure, and the lower end of the cylinder is set
There are outside folded edges, protrusion or groove are equipped between the crimping and flanging of lid cylinder, protrusion and groove were formed
It is full of fastening structure.
Due to taking above-mentioned technical solution, a kind of cutlery box provided by the invention has such the utility model has the advantages that passing through box
Body and the isostructural combined innovation of lid, it is simple to provide a kind of structure, at low cost, operation and disposable lunch-box easy to use, tool
Having prevents the secondary ability used, can guarantee food safety, while the product of papery can degrade, and meets modern environmental protection and wants
It asks.
