Description

A kind of food box

Technical field

The utility model relates to a kind of food containers, especially a kind of food box.

Background technology

When we open food box, in the process of eating, food inside box constantly reduces, and food heights constantly declines, from box mouth distance more and more away from, must reach inside box and remove clamping food, box body is more long more inconvenient, uses inconvenience especially, when using food box in addition concerning children old man, also need to carry independently chopstick box, carry inconvenience.

For above deficiency, be necessary very much to develop a kind of structure simple, novel foodstuff box easy to use.

Utility model content

For solving the problems of the technologies described above, the utility model provides a kind of food box of applicable dress large grained food, and no matter food is many or few, makes food be in box mouth place all the time, simple for structure, easy to use.

The utility model is achieved through the following technical solutions: a kind of food box, comprises lid, box body, chassis and at least one spring;

Described lid and described box body removably connect;

Described chassis and described spring are all placed in described box body, described spring at the bottom of the box of described chassis and described box body between, described chassis liftable in described box body moves.

In such scheme, also comprise chopstick box, described chopstick box is fixed on the end face of described lid.

Further, the opening of described chopstick box is located at side or located in the above.

In such scheme, described lid, described box body and described chassis are cylindrical.

Further, described lid and described box body are threaded connection.

In such scheme, edge, described chassis is provided with sidewall.

In such scheme, described spring is round screw thread spring.

Further, the number of described spring is 3, and the internal diameter of described 3 springs varies in size.

Beneficial effect:

1, adopt the relation of gravity and elastic force, chassis adopts can the design of automatic lifting, and no matter food is many or few, makes food be in box mouth place all the time, makes food consumption conveniently.

2, chopstick box is integrated with lid, can be used as screw capping handle and uses, simple for structure, easy to use.

3, described spring is round screw thread spring, and its relation with application force and displacement is sensitive, and softness is good, and structure comparison is compact, the advantage that energy interest rate is high.

4, described spring is that 3 internal diameters vary in size, and the spring that stiffness factor is different, can realize the selection of 7 kinds of different stiffness factors, if food density is different, by independent assortment, between the density region that can increase food, can better adapt to its change.

Detailed description of the invention

In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", "left", "right", " top ", " end " " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.

In the utility model, unless otherwise clearly defined and limited, the term such as term " installation ", " being connected ", " connection ", " fixing " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, the concrete meaning of above-mentioned term in the utility model can be understood as the case may be.

Figure 1 shows that a kind of embodiment of food box described in the utility model, described food box, comprise lid 1, box body 2, chassis 3, at least one spring 4 and chopstick box 5.

Described lid 1, box body 2 and chassis 3 are cylindrical, but are not limited only to this.Described lid 1 and described box body 2 removably connect; Described lid 1 and described box body 2 are preferably by being threaded.

Described chassis 3 and described spring 4 are all placed in described box body 2, described spring 4 at the bottom of the box of described chassis 3 and described box body 2 between, described chassis 3 outer wall and described box body 2 inwall have certain gap, and under the effect of described spring 4, described chassis 3 liftable in described box body 2 moves.Edge, described chassis 3 is provided with the sidewall 301 of certain altitude, forms the space of containing foodstuff.

As shown in Figure 3, described chopstick box 5 is fixed on the end face of described lid 1, is integrated design with described lid, can be used as screw capping handle and uses; The opening of described chopstick box 5 is located at side or located in the above.

Described spring 4 is round screw thread spring, and its relation with application force and displacement is sensitive, and softness is good, and structure comparison is compact, the advantage that energy interest rate is high.

Described spring 4 is preferably 3 springs of independent assortment, described 3 springs 4 vary in size for internal diameter, spring A, spring B, spring C that stiffness factor is different, the selection of 7 kinds of different stiffness factors can be realized: spring A, spring B, spring C, spring A spring B, spring A spring C, spring B spring C, spring A spring B spring C, if food density is different, by independent assortment, between the density region that can increase food, its change can better be adapted to.

The utility model principle:

The utility model adopts Hook's law, and for described spring 4, represent its stiffness factor, represent quality of food with m with K, X represents chassis displacement, and chassis area is A, and acceleration due to gravity is g,

Then △ mg=K △ X 1.

If food density is even, represent with ρ, if the top of food is to the height decline △ H on chassis, Mass lost △ m,

Namely △ mg=ρ Ag △ H 2.

By 1., 2. know, △ H=△ X be made, then K=ρ Ag.As long as so make device of spring stiffness coefficient K close to ρ Ag, wherein variable only has food density ρ.

According to put food independent assortment in described 3 springs 4, choose described spring 4, food is put in described chassis 3, when food heights reduces △ H, rise △ H under the effect of described spring 4 on described chassis 3, thus make the distance at the bottom of food top and box remain at L height, as shown in Figure 2, left side food is many, the right food tails off, no matter food is many or few, makes food top be in box mouth place all the time, makes food consumption convenient.

Described embodiment is preferred embodiment of the present utility model; but the utility model is not limited to above-mentioned embodiment; when not deviating from flesh and blood of the present utility model, any apparent improvement that those skilled in the art can make, replacement or modification all belong to protection domain of the present utility model.
