Description

With oneself folding automatic lunch box

The utility model provides a kind of food service items, is a kind of auto-folder lunch box of being convenient to carry specifically.

Normally used lunch box constitutes by joining a corresponding lid on the box body mostly, in recent years, improves on the lunch box some that great majority concentrate on the external form, in the moulding, and it is excessive all to have a volume, should not carry and wait deficiency.

The purpose of this utility model is to provide a kind of to be convenient to carry, volume is small and exquisite, lunch box volume-diminished when shrinking, and lunch box uses the with oneself folding automatic lunch box that volume strengthens when opening.

Embodiment of the present utility model is: by up and down two covers of the lunch box, gripper shoe, folding lunch box body etc. are formed.Flexibly connect with gripper shoe respectively in the two lid opposite ends, being equipped with respectively on two gripper shoes can be by the spring assembly of automatic pull-up, and being fixed with folding between gripper shoe and the lid is the lunch box body of skeleton with gripper shoe and lid.When opening box body, last lower casing and gripper shoe automatically spring open under the pulling force of spring, and two lids are 180 ° of arrangements, and gripper shoe is propped, and drive folding lunch box and launch, and last lower casing becomes the end of lunch box, and gripper shoe is two side support plates of lunch box body.

Said going up on the lower casing has a corresponding grooves and projection respectively, and the buckle on resting and reorganizing with common composition box is with the closure of convenient mess tin body.

One rotatable 180 ° clamp is arranged on the lid, respectively there is a circle recessed at lid and both sides, clamp junction, the corresponding positions of clamp is equipped with two projectioies, and when packing up, the projection of clamp changes groove over to, so that clamp is fixed, this moment clamp can be used as hang hairpin or belt card not on one's body, when using lunch box, the clamp Rotate 180 ° is stretched out, the conversion of clamp projection falls into the groove chucking again for 180 ° and fixes, and clamp can be used as the handle of end lunch box.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Among Fig. 1, Fig. 2, clamp 3 is contained on the lid 2 by screw 4, with both sides, clamp 3 junction one circle recessed 17 is arranged respectively on the lid 2, corresponding positions on the clamp 3 is equipped with two projectioies 18, when clamp 3 tightly is installed on the lid 2 by screw 4, if clamp 3 is when the strength rotation of hand, projection 18 will produce, and when changeing 180 °, projection 18 will change recessed 17 places of circle again under the restoring force of material, can both fix firmly and will be difficult for double swerve no matter revolve preceding supination clamp 3 like this.16 are hole, connection garden.

Among Fig. 3, lid 1,2 flexibly connects with

plastic support board

5,6 respectively in the relative both sides, on the

plastic support board

5,6 spring assembly is housed respectively.

Among Fig. 4, the lunch box body 7 of unlimited rectangular build suitable for reading is the folded flexible plastic of folding, and lunch box body 7 the right and lefts be bilayer, shut at the top, is enclosed within on the

plastic support board

5,6 of bottom skeleton, is propped by

plastic support board

5,6 to strut, form a container, and with lid 1, be bottom support.This kind structure is convenient to the replacing of lunch box body.

Among Fig. 5, spring 10 is fixed in the interlayer of cover of the lunch box 1,2 by plastic plate 11 respectively, and the other end of two springs 10 is connected with

projection

8,9 on the plastic support board 5,6.Among the figure situation that plastic support board is pressed mutually under the lunch box closed condition, spring elongation this moment, after lunch box was opened, gripper shoe was pulled up under the pulling force of spring.

Among Fig. 6, Fig. 7, Fig. 8,6 is plastic support board, and 8 for connecting the projection of spring assembly, and 13 is the commissure seat on the lid, and gripper shoe 6 is connected latch 12 with commissure seat 13 by one and connects.

Among Fig. 9, there is a hook 14 at lid 2 bayonet socket places, one interlaced projection and recessed is arranged on the last lower casing, the common buckle of forming, when lunch box was closed, plastic support board had a kind of power of mutual top under the putting forth effort of spring, the trend of backing down lid is arranged, buckle on the lid is convenient to closing of box body at this moment, and in can preventing that box body from closing in the dust of back.Among the figure, the hook 14 of lid 2 will inwardly have certain deformation S under the pressure F of hand effect, fall into and cover 1 groove 15, and at this moment lunch box covers and closes.When opening, available finger is given a pressure F ₂, hook 14 will have a distortion S ¹, and from groove 15, deviate from, can open box body.

Among Figure 10,1,2 is lid, 3 is clamp, 7 is lunch box body, 5,6 is gripper shoe, in the time will using this lunch box, be used in reference to plastics hook 14 is pressed in box, hook stress deformation and leave the groove 15 that catches on it, lid 1,2 separately, at this

moment gripper shoe

5,6 under the situation that pressure is removed each other, hold up under spring 10 pulling force in the lid interlayer, when lid 1,2 when being opened into 18 °, just become the bottom bracing of lunch box, the gripper shoe 5 that erects, 6 is two lateral support of lunch box, they resemble the skeleton of umbrella lunch box body are propped up, become container, then clamp 3 Rotate 180s are become one handle, be convenient to use the hand end.

The utility model structure is small and exquisite, lunch box volume-diminished during contraction, be convenient to carry, lunch box uses volume can increase several times when opening, if it is narrower that the interlayer of lid is done, and the volume after lunch box shrinks is the addition of two lids, and Ci Shi volume only will be to launch back volume number/one so.The convenient use, be adapted to student, tourism, and the people of field work use.
