Description

Thermal insulating bag for lunch-box

The utility model relates to a kind of lunch box insulated bag, belongs to the technical field of daily necessities.

Worker's working at present is not because work unit has ad hoc dining room, if in the streets having dinner in the restaurant, because sanitary condition is not ideal enough, be afraid of to infect diseases such as hepatitis, though the appearance of existing disposable lunch box, because food quality taste, factors such as price, so people redeem a vow to a god and provide lunch box for oneself and carry food and have a meal, because the difference in season can not eat colder food, if there is not the facility of steaming, also make the use of lunch box be subjected to certain restriction, therefore must consider how to make lunch box can keep certain temperature, just can make things convenient for much when edible, but still lack simple and easy suitable insulation utensil at present.

The purpose of this utility model is that a kind of lunch box insulated bag will be provided, it can overcome above-mentioned shortcoming, the lunch box that fills with food is placed insulated bag, can make food keep certain warm degree, needn't heat again when edible, be not subjected to the restriction of place or heater, thereby make the eater feel convenient.

The purpose of this utility model is achieved in that

Insulated bag is integral admittedly by surface layer, adiabator layer and internal layer three layered sutures, again with bottom, and adiabator layer, internal layer is seamed into one bag of shape along the seam solidus, is sewed with zip at the right part of insulated bag, and surface layer has a tongue just in time to cover zip partly.Zip can stitch be fixed in insulated bag around.Adiabator layer is made with foamed plastics or cotton, silk flosssilk wadding.

Fig. 1 is the insulated bag schematic diagram.

Fig. 2 is the insulated bag partial sectional view.

Fig. 3 is the A-A cutaway view of Fig. 1.

Fig. 4 is insulated bag user mode figure.

Fig. 5 is the insulated bag schematic diagram of another kind of structure.

Now in conjunction with the accompanying drawings the structure of lunch box insulated bag is described in detail:

By Fig. 1; use nylon taffeta or bright silk to be sewn into insulated bag (1); when making; stitch solid along seam solidus (2); at the right part of insulated bag, be sewed with zip (3) on its surface layer (5), and surface layer right part (5) there is a tongue (4) just in time can cover zip (3); therefore can not see zip (3) from the surface, zip is also played the certain protection effect.

By Fig. 2, the surface layer (5) of insulated bag (1) and heat insulating material layer (6) and internal layer (7) seam that is superimposed is solid together, and heat insulating material layer can be space wadding foamed plastics or cotton, silk flosssilk wadding.

By Fig. 3, bottom of insulated bag (8) and adiabator layer (9) and internal layer (10), equally also seam is integral admittedly.

By Fig. 4, during use, raise the tongue (4) of surface layer (5) right part, pulling zip (3) just can be seated in the lunch box that fills food (11) in the insulated bag (1), locks zip (3) then.

By Fig. 5, the structure of this insulated bag (1) is similar with Fig. 1, just zip (11) partly be contained in bag around.Same surface layer (5) and bottom (8) also have the tongue of certain width, can cover in zip (11).

Compared with prior art, lunch box thermal protective bag has following advantages:

1. can be incubated about 5～6 hours.

2. light, be easy to carry.

3. outer field bottom, the color and luster style is bright-coloured.

4. foamed plastics has the effect of protection lunch box concurrently, is not afraid of the collision extruding.
