CN201451827U - Fresh-keeping lunch box - Google Patents

Abstract

The utility model relates to a lunch box, in particularly to a fresh-keeping lunch box. The fresh-keeping lunch box comprises a thermal insulation top plate, a box cover, a box body, a thermal insulation cylinder, an ice block, a thermal insulation base plate, a meal storing cavity and a bottom plate, wherein the thermal insulation top plate is bonded into the space of an oblate cylinder of the box cover. Two ring-shaped partitions, including an inner ring-shaped partition and an outer ring-shaped partition, are formed on the inner side of the box body. The lower end of the inner partition adopts the bottom plate perpendicular to the inner partition, and the outer edge of the bottom plate is connected to and mutually perpendicular to the inner wall of the outer partition. The ice block is positioned in an annular space formed by the inner and the outer partitions of the box body. The thermal insulation top plate, the thermal insulation cylinder and the thermal insulation base plate are all made of polystyrene foam. Because the ice block is positioned in a closed space made of polystyrene foam, the meals inside the meal storing cavity can be kept under a low temperature for a long time, thereby achieving good fresh-keeping effect.

Description

Fresh-keeping cutlery box

Technical field

The utility model relates to a kind of cutlery box, particularly relates to a kind of fresh-keeping cutlery box.

Background technology

Existing fresh-keeping cutlery box normally only reaches the fresh-keeping purpose of food by airtight performance preferably.But, for the working clan who carries lunch, in temperature higher summer, food need be deposited the above time of half a day, even cutlery box has seal preferably, the harmful bacteria in the cutlery box also can be bred with fast speed, and the food of depositing like this is harmful to human body.

The utility model content

The utility model provides a kind of and can food be deposited the fresh-keeping cutlery box of long period under higher temperature for solving the deficiencies in the prior art.

The scheme that solves the utility model technical problem is: fresh-keeping cutlery box is taken over a business, lid, box body, heat-preservation cylinder, ice cube, insulation chassis, is deposited the meal chamber and base plate constitutes by insulation.Wherein, the outline of lid and box body is cylindrical, and lid is placed on the upper end of box body, and with box body with threaded engagement.There is a circle annular and separation inboard of lid, and this separates the space in the lid is divided into a peripheral ring annular groove and the oblate cylindrical space at middle part.The insulation of oblate cylindricality takes over a business to be adhered in the oblate column space of described lid.There are inside and outside two circle annular and separations the inboard of box body.Interior lower end of separating is and the perpendicular base plate of interior separation that the outer of base plate joins with the outer inwall of separating and be vertical mutually.Columnar heat-preservation cylinder is in the annular space that outer separation constituted of the outer wall of box body and box body.Ice cube is in the annular space that inside and outside separation constituted of box body.The insulation chassis is in the oblate space bottom the box body that outer separation and base plate by box body constituted.The columniform meal chamber of depositing of the common formation of the interior separation of box body and base plate.Described insulation is taken over a business, the material on heat-preservation cylinder, insulation chassis is polystyrene foam plastics.The material that insulation is taken over a business with box body is a polytetrafluoroethylene (PTFE).Before depositing food, earlier put into ice cube in the annular space that inside and outside separation constituted with box body, keep after the food lid covered to screw on box body and get final product.

Adopt such scheme, can reach following effect:

Because ice cube is in by in the extremely low confined space that polystyrene foam plastics was surrounded as of thermal conductivity factor, external heat is very faint to the influence of box body temperature inside.Lid and box body can be combined closely by screw thread simultaneously.Therefore the ice cube of box body inside can keep low temperature with the food of depositing in the meal chamber for a long time, has reached good fresh-keeping effect.

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1. be incubated 2. lids, 3. box bodys, 4. heat-preservation cylinders, 5. ice cubes, 6.insulation chassis 7. anddeposit meal chamber 8. base plates

The specific embodiment

The utility model will be further described below in conjunction with drawings and Examples.

Fresh-keeping cutlery box takes over abusiness 1 by insulation,lid 2,box body 3, heat-preservation cylinder 4,ice cube 5,insulation chassis 6,deposit meal chamber 7 andbase plate 8 formations. wherein, the outline oflid 2 andbox body 3 is cylindrical,lid 2 is placed on the upper end ofbox body 3, and withbox body 3 with threaded engagement. the inboard oflid 2 have one the circle annular and separation, this separates the space in thelid 2 is divided into a peripheral circle annular space and the oblate cylindrical space at middle part. and the insulation of oblate cylindricality is taken over abusiness 1 and is adhered in the oblate column space of describedlid 2. in the inboard ofbox body 3 has, outer two circle annular and separations. the lower end of interior separation is thebase plate 8 perpendicular with interior separation, the outer ofbase plate 8 joins with the outer inwall of separating and is vertical mutually. columnar heat-preservation cylinder 4 is in the annular space that outer separation constituted of the outer wall ofbox body 3 andbox body 3. ice cube be inbox body 3 in, the outer separation in the annular space that is constituted. the outer separation ofbox body 3 andbase plate 8 constitute the oblate space ofbox body 3 bottoms,insulation chassis 6 is in the oblate space ofbox body 3 bottoms. and the outer wall ofbox body 3 and outer upper end of separating are in the annular space of describedlid 2. and the interior separation ofbox body 3 andbase plate 8 be common to be constituted and columniformlydeposits meal chamber 7. described insulations and take over abusiness 1, heat-preservation cylinder 4, the material oninsulation chassis 6 is polystyrene foam plastics. and the material oflid 2 andbox body 3 is a polytetrafluoroethylene (PTFE). before depositing food, earlier with in thebox body 3, the outer separation in the annular space that is constituted put intoice cube 5, keeps after thefood lid 2 covered to screw onbox body 3 to get final product.
