Abstract
The utility model discloses a kind of bottom self-locked formula aviation paper lunch-box, the folding section of the triangle of two homonymies is set on the paper lunch-box bottom self-locked, the folding section and the wedge angle position of bottom self-locked are provided with gap, and the long side position that the folding section is connected with bottom self-locked is provided with impression.Bottom self-locked formula aviation paper lunch-box described in the utility model, folding section wedge angle position is provided with gap, long side position is provided with impression, primarily to when folding, avoids there is a situation where corrugation or folds not in place, control folding angles and impression length simultaneously, play it is beautiful and more time saving and energy saving, suitable for mass production by machines process, this is simple in structure, handling ease realizes that practical effect is notable.
Description
Technical field
The utility model is related to a kind of aviation paper lunch-box, especially a kind of bottom self-locked formula aviation paper lunch-box belongs to food
Product packing technique field.
Background technology
Existing aviation paper lunch-box, majority can be converted into flat using automatic locking bottom structure, the i.e. box body of cutlery box and cassette bottom
Plate, when box body struts, cassette bottom can revert to sealing state automatically, need not in addition organize underseal and.Bottom self-locked cutlery box has
The characteristics of firm, efficient beautiful, but since its structure is relative complex, manufacturing schedule is slower, and cost of manufacture is higher.
Existing bottom self-locked formula aviation paper lunch-box, in process, since part-structure needs to fold its easy
Wrinkle, surface is not smooth enough, and often folds situation not in place, and cutlery box is caused to deform, and influences actual use and integrated beauty
It sees.
Utility model content
The utility model is exactly in view of the deficienciess of the prior art, providing a kind of bottom self-locked formula aviation paper lunch-box.
To solve the above problems, technical solution adopted in the utility model is as follows：
A kind of bottom self-locked formula aviation paper lunch-box sets the folding of the triangle of two homonymies on the paper lunch-box bottom self-locked
At conjunction, the wedge angle position of the folding section and bottom self-locked is provided with gap, the long leg that the folding section is connected with bottom self-locked
Position is provided with impression.
As the improvement of above-mentioned technical proposal, long side and the horizontal line angle β of the folding section are 45 °.
As the improvement of above-mentioned technical proposal, the relation between the long edge lengths H of the folding section and the length L of impression
For：1/2H≤L≤2/3H.
Compared with prior art, the implementation result of the utility model is as follows：
Bottom self-locked formula aviation paper lunch-box described in the utility model is provided with gap, in long side at folding section wedge angle position
Position is provided with impression, primarily to when folding, avoids occurring corrugation or folds not in place, while control folding
Folded angle and impression length, play beautiful and more time saving and energy saving, and suitable for mass production by machines processing, this is simple in structure, adds
Work is easy to implement, and practical effect is notable.
Description of the drawings
Fig. 1 is aviation paper lunch-box bottom self-locked structure diagram described in the utility model.
Specific embodiment
Illustrate the content of the utility model below in conjunction with specific embodiments.
As shown in Figure 1, it is aviation paper lunch-box bottom self-locked structure diagram described in the utility model.
Aviation described in the utility model paper lunch-box bottom self-locked sets the folding section 20 of the triangle of two homonymies on bottom self-locked,
The folding section 20 and the wedge angle position of bottom self-locked are provided with gap 10, the long leg that the folding section 20 is connected with bottom self-locked
Position is provided with impression 30.The folding section 20 easily wrinkles or folds situation not in place when folding, and sets gap 10
It ensure that the folding section 20 after folding will not wrinkle, surfacing, beauty.The impression 30 ensure that folding section 20 along long side
When being folded, accurately positioned, folding section 20 will not be allowed to become larger or become smaller, at the same it is more time saving and energy saving folded,
Beneficial to personnel's operation or machine foldable.
Aviation described in the utility model paper lunch-box bottom self-locked, in order to realize that self-locking bottom structure and surfacing are beautiful,
The long side of folding section 20 is 45 ° with horizontal line angle β, and self-locking and beauty are realized after so folding.The long side of the folding section 20
Relation between length H and the length L of impression 30 is：1/2H≤L≤2/3H so ensure that along impression 30 and fold time saving province
Power, at the same also utmostly reduce compression moulding impression 30 when mold abrasion.
The above content is the detailed descriptions made in conjunction with specific embodiments to the utility model, it is impossible to assert that this practicality is new
Type specific implementation is only limitted to these explanations.For those skilled in the art of the present invention, this is not being departed from
On the premise of utility model is conceived, several simple deduction or replace can also be made, should all be considered as belonging to the utility model guarantor
The scope of shield.
