Detailed description of the invention

Embodiment 1:

As shown in Fig. 1 ~ 10, a kind of Hygienic lunch-box be convenient for carrying, comprises lunch box body 1, end box 2 and receiver 3.

The hollow cylinder of end box 2 in closed at both ends, its periphery is provided with external screw thread 24, and its bottom surface is provided with openable bottom 21, and its end face is provided with freshness protection package and portals 22.Be provided with the bulge loop A23 stretched out vertically outside end face, bulge loop A23 outer wall is provided with external screw thread 231.When end box 2 is threaded with annular element 11 minimum in lunch box body 1 by external screw thread 231, end box 2 inner being portalled by freshness protection package with lunch box body 1 inside 22 is communicated with.

Lunch box body 1 by the identical annular element 11 of at least two shapes by size order be socketed to form successively.The straight-tube shape annular of annular element 11 in zero draft.The periphery of annular element 11 is provided with elasticity raised line 111, and the two ends up and down of annular element 11 inwall are respectively equipped with the upper locating slot 112 and lower locating slot 113 that can match with elasticity raised line 111.Between adjacent annulus 11 slidably, to make lunch box body 1 entirety stretch or shrink.The internal thread 12 matched with the external screw thread 231 of end box 2 is provided with in the inwall of annular element minimum in lunch box body 1.

Receiver 3 closes the tubular of one end open in one end, be provided with the internal thread 33 matched with the external screw thread 24 on end box 2 periphery in the inwall of its opening part, the bottom surface of its inside is provided with the bulge loop B31 stretched out vertically.Knife and fork buckle 32 is provided with in bulge loop B31.The periphery of bulge loop B31 is provided with the external screw thread 311 matched with the internal thread 12 on annular element 11.

Embodiment 2:

Difference is only compared with embodiment 1, and annular element is the conical ring that lower end is greater than upper end, and tapering is 0 ° ~ 5 °, and the present embodiment is not shown.

Sketch use of the present utility model: as shown in Figure 2,4, when needing dining, stretching lunch box body 1, makes the elasticity raised line 111 on each annular element 11 fall into the lower locating slot 113 of upper level annular element 11.Again lunch box body 1 is connected on the bulge loop A23 of end box 2 by internal thread 12.Open the bottom 21 of end box 2 afterwards, the freshness protection package folded is put into end box 2, again freshness protection package is portalled in 22 from the freshness protection package end box 2 and extract out, be enclosed within stretched lunch box body 1 and can have dinner, receiver 3 can make separately nappy or soup bowl uses, after the meal freshness protection package is abandoned, without the need to cleaning lunch box body 1 and end box 2.
