Abstract

The invention belongs to common metal container process industry and general rubber product industry.

Realize that the subject matter that the present invention need solve has:

Want rationally in the gap that cooperates between A, lid [7], big lunch box [2], dish box [5], the rubber seal [6].

That the manufacturing of B, rubber seal [6] will be selected for use is nontoxic, oil resistant, resistant to elevated temperatures elastomeric material, the water-bearing channel of rubber seal outside system twice horizontal direction.

The shape spring [3] of C, manufacturing will guarantee stable elasticity.Elastic force when single spring is worked remains on 1.5 kilograms approximately for best, antirust chromium plating.

The present invention has thoroughly solved the outside leakage problems of soup in the lunch box in the past, has guaranteed not pollute the article that contacts with this lunch box, and has accomplished that this lunch box interior staple food and dish do not obscure, and utilizes the handle [10] to carry the lunch box of high temperature, low temperature at any time.This lunch box also can be used for others.

Description

Sealed combined messtin

The present invention combines lunch box, dish box, has the combined lunch box of sealing characteristics.Also can use as other container.

For many years we use always by lid and the lunch box formed of box.If use a lunch box.Food can only be mixed being fitted together, eat very inconveniently, just be difficult to eat if wheaten food and dish are fitted together that, turn sour but also exist easily, problems such as seepage especially because leakage problems is not only polluted article such as clothes, and cause dispute in public places.

Obscure problem in order to solve, we use dish box of a lunch box usually.In order to solve the pollution problem that causes because of seepage, we are normal to adopt to go into polybag or with towel lunch box, dish box are wrapped lunch box and dish are box-packed, perhaps is not with thousand and one ways such as dish box, but all can not addresses these problems at all.

The objective of the invention is to provide a kind of sealed combined messtin.It not only can closely be combined lunch box and dish box, and accomplishes that food do not obscure, and assorted flavor is not sneaked in heating in the meal case, and the soup in lunch box and the dish box is outside seepage, does not pollute all contact article.And hot and cold lunch box can carry at any time.

Invention is achieved in that at first manufactures the big lunch box [2] that the bottom has groove, manufacture the rubber seal [6] that outside horizontal direction has three water-bearing channel according to big lunch box [2], and be installed on the big lunch box [2], doing flange place root has the dish box [5] of fillet, be sitting on the rubber seal [6], lid [7] lid that will have groove then is tight, becomes meal, dish part.Use at last by degree of lip-rounding cutting ferrule [1], shape spring [3], the lock sleeve that expansion plate [4], pressing plate [8] are formed is partly locked lunch box, dish box, dress is self-locking clamp [9] and handle [10] at last, whole process finishes.

In whole process, because the effect of coupling mechanism force, the fillet of dish box [5] flange place root tightly is pressed on the rubber seal [6] all the time, produce a kind of downward pressure and outside expansive force, the several surfaces of rubber seal are all contacted with big lunch box [2], dish box [5], lid [7] respectively closely, and the sealing effectiveness that obtains has played supporting role by rubber seal [6] in level with the bottom of delicacies of the season box [5], improved the intensity of sealed combined messtin greatly.

The present invention reforms on the basis of old-fashioned lunch box, and changed under the situation of old-fashioned lunch box shape and combining form and increased a sealing ring and lock sleeve, thus single between structure, neither need special material, do not need high technology again, realize easily.

Accompanying drawing 1 is the plane of sealed combined messtin.Accompanying drawing 2 is the profiles according to sealed group of packed meal box of invention proposition

(1) expression U-shaped cutting ferrule in the accompanying drawing 2. Be stuck in the groove of big lunch box.

(2) expression is with the big lunch box of groove.

(3) the shape spring of expression. Be contained in the loose slot of U-shaped cutting ferrule and expansion plate composition.

(4) expression is contained in figure [1] but the expansion plate of easy on and off activity under the effect of inner spring.

(5) expression flange place root has the dish box at angle, garden.Under the effect of power, the fillet of dish box root produces downward power and outside expansive force, and the several times machine of rubber gasket contacts closely with lid, dish box, big lunch box respectively like this.

(6) expression outside horizontal direction has the rubber seal of 3 water-bearing channels.This circle height equates with the height of lid (7) and dish box (5), uses soft rubber manufacturing nontoxic, oil resistant high temperature.

(7) lid of expression band groove.

(8) expression pressing plate.Two cooperates with slotted hole on the expansion plate respectively.

(9) represent automatic clamp.Can be up and down at handle.

(10) the expression handle is made with the spring steel wire of 2 millimeters of diameters, owing to have elasticity, two of handle hook when the self-locking clamp is downward, two apertures of pressing plate (8), on the contrary two hooks of handle just eject.

Claims

1, dish box, two containers of lunch box are combined closely, become sealed combined messtin.It is characterized in that:

One rubber seal [6] is arranged in a, the described sealed combined messtin, play sealing and fixed position;

There is a lock sleeve b, described sealed combined messtin outside, by the U-shaped cover, [1], shape spring [3] expansion plate [4], pressing plate [8] is formed.

2, according to claim 1, its feature is applicable to the combination of various container of material.
