Abstract
The utility model discloses a kind of lunch box capable of heating, comprise box body and lid, the junction of described lid and box body is provided with slide fastener, the upper limb of described lid opposing zippers be provided with can cover described in draw chain flexibility catch, the lower edge of described box body opposing zippers is provided with bristle layer, one end of the relative box body of described catch is provided with raw wool layer, described raw wool layer and bristle layer form laminating mutually, according to said structure, under the prerequisite not expanding overall dimensions, the connection that just can be realized lid and box body by slide fastener is coordinated, thus achieve the effect of small size, be easy to carry, and pass through flexible baffle, the situation that the junction of lid and box body generation heat leaks can be prevented.
Description
Technical field
The utility model relates to a kind of lunch box, and more particularly, it relates to lunch box capable of heating.
Background technology
Lunch box capable of heating is a kind of New lunch box, has insulation, heating function.Generally all adopt food-grade PP material as shell, adopt circulating ptc heater to heat.Compared to traditional ordinary lunch-box or incubation canteen, there is plug-in heating, numerous advantage such as easy to carry.
But existing lunch box capable of heating, uses hasp to be connected with the fit system of lid at box body usually, and so, hasp will be exposed at the periphery of box body, the overall volume of profile not only can be made to become large, and also cannot play good effect for the insulation in lunch box.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of lunch box capable of heating, by this lunch box capable of heating, after having heated in lunch box, by the cooperation of lid and box body, can play good heat insulation effect, and volume is little, is easy to carry about with one.
For achieving the above object, the utility model provides following technical scheme: a kind of lunch box capable of heating, comprise box body and lid, the junction of described lid and box body is provided with slide fastener, the upper limb of described lid opposing zippers be provided with can cover described in draw chain flexibility catch, the lower edge of described box body opposing zippers is provided with bristle layer, and one end of the relative box body of described catch is provided with raw wool layer, and described raw wool layer and bristle layer form laminating mutually.
By adopting technique scheme, being realized the connection of box body and lid by slide fastener, avoiding the mode by hasp in prior art, thus create the volume outwards increased, make the overall volume of lunch box become large, be unfavorable for carrying; And the flexible catch by described slide fastener being covered completely; further decrease the heat exchange between tray interior and the external world; further ensure that the heat insulation effect of lunch box; by this mode of VELCRO; realization is located at the flexible catch on lid and is fitted tightly with box body, and can also protect slide fastener.
The utility model is set to further: described slide fastener is provided with pull head, and described flexible catch is provided with stopper slot, and described pull head is limited in stopper slot.
By adopting technique scheme, by the stopper slot suitable with pull head that flexible catch is arranged, make after the flexible catch of laminating, described pull head can be limited in stopper slot, slide fastener will be opened due to uncertain factor, thus box body is separated with lid generation, make lunch box lose heat insulation effect, or the meal in lunch box is dropped in transportation.
The utility model is set to further: described lid is provided with the rubber flange of downward projection relative to one end of box body, and the opening of described rubber flange and affiliated box body forms interference fit.
By adopting technique scheme, by this circle rubber flange, after lid and box body formation cover, form sealing effectiveness closely, the heat insulation effect of lunch box will promote greatly.
The utility model is set to further: described flexible catch is made up of polystyrene.
By adopting technique scheme, the physical property of this material of polystyrene is colourless, odorless, tasteless, has good insulation, effect of heat insulation, and is soft heart mutability, long perfomance life.
Compared with prior art, the utility model has the advantage of: under the prerequisite not expanding overall dimensions, the connection that just can be realized lid and box body by slide fastener is coordinated, thus achieve the effect of small size, be easy to carry, and by flexible baffle, the situation that the junction of lid and box body generation heat leaks can be prevented.

Detailed description of the invention
With reference to accompanying drawing 1 to 5, the embodiment of the utility model lunch box capable of heating is described in further details:
The present embodiment comprises box body 1 and lid 2, one end of the relative box body 1 of described lid 2 is provided with the rubber flange 22 of downward projection, described rubber flange 22 forms interference fit with the opening of affiliated box body 1, the junction of described lid 2 and box body 1 is provided with slide fastener 3, the upper limb of described lid 2 opposing zippers 3 is provided with the flexible catch 4 that can cover described slide fastener 3, described flexible catch 4 is made up of polystyrene, the lower edge of described box body 1 opposing zippers 3 is provided with bristle layer 5, one end of the relative box body 1 of described catch is provided with raw wool layer 41, described raw wool layer 41 and bristle layer 5 form laminating mutually, described slide fastener 3 is provided with pull head 31, described flexible catch 4 is provided with stopper slot 42, described pull head 31 is limited in stopper slot 42.
According to said structure, lid 2 is covered on box body 1, the rubber flange 22 coordinated with the opening of box body 1 will produce enjoyable cooperation with opening and realize fitted seal closely, zip up 3, the docking realizing lid 2 and box body 1 is sealed, again flexible catch 4 is covered on slide fastener 3, the bonding of flexible catch 4 is realized by raw wool layer 41 and bristle layer 5, in addition in order to increase heat insulation effect, flexible catch 4 has polystyrene to make, heat in further minimizing lunch box is spilt by slide fastener 3 place, avoid the heat exchange between box body 1 inside and the external world, box body is provided with venthole 21, this venthole 21 is generally unidirectional and gives vent to anger, lunch box is in heating process, vapours sheds by the venthole 21 be arranged on lid, avoid the pressure in box body excessive and be damaged.
Further, when lunch box is in transportation, by the stopper slot 42 suitable with pull head 31 that flexible catch 4 is arranged, make after the flexible catch 4 of laminating, described pull head 31 can be limited in stopper slot 42, slide fastener 3 will be opened due to uncertain factor, thus box body 1 is separated with lid 2 generation, make lunch box lose heat insulation effect, or slide fastener 3 is opened, the meal in lunch box is dropped in transportation.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
