Abstract

The utility model relates to a multilayer plastic sealed lunch-box with hoop handle, which can prevent soup-meagre from overflowing effectively. The plastic sealed lunch-box with hoop handle is composed of a hoop handle, a box cover, 2-4 box bodies, plastic seal rings which are arranged between the box cover and the box body and the upper box body and the lower box body, and a locking device.

Description

Plastic sealed lunch-box with hoop handle

The utility model relates to the improvement of bale handle formula multilayer lunch box.The bale handle formula multilayer lunch box that China uses for a long time is subjected to liking of working people deeply, also widely uses up to now.But this lunch box can not seal, the time have the situation that vegetable soup overflows to take place, not only cause the loss of vegetable soup, the clothing around also often polluting simultaneously.In order to overcome this shortcoming, the utility model provides a kind of bale handle formula multilayer lunch box that can prevent that vegetable soup from overflowing, and this is by between lid and box body, and the installing plastic seal ring reaches between upper strata box and lower floor's box.That plastic seal ring adopts o type (cross section is for circular) or n type (cross section is a hat), material can be a rubber, also can be flexible plastic, but all should meet the health conditions requiring of containing with food.

In order to make lid edge, box feather edge and the box mouth edge can be closely connected, they be made the circular arc concave surface tangent with sealing ring, or box mouth edge is embedded in the plastic seal ring, and compress by locking device with plastic seal ring.Locking device can be various forms of, as screw locking type, eccentric bushing locking type, turn over beam locking type etc., but requires plastic seal ring evenly stressed, and compression ratio is in the 15%-50% scope.

Below in conjunction with embodiment the utility model is further described.Accompanying drawing of the present utility model has:

The multilayer lunch box of Fig. 1 band o RunddichtringO and screw locking device

The multilayer lunch box of Fig. 2 band n RunddichtringO and eccentric bushing locking device

The multilayer lunch box of Fig. 3 band n RunddichtringO and eccentric wheel locking device

Fig. 4 has the multilayer lunch box of steel core o RunddichtringO and eccentric disk locking device

The multilayer lunch box of Fig. 5 band n RunddichtringO and flip beam shrinking device

The multilayer lunch box of the tight device of Fig. 6 band n RunddichtringO and handle lock

The numbering of each element is as follows among the figure:

1-lid 2-sealing ring 3-box body 4-locks beam

5-nut 6-bale handle 7-locking frame 8-locking frame hook bar

9-rivet shaft 10-eccentric bushing 11-flip beam 12-locks beam casing

13-eccentric disk 14-side ring 15-rivet 16-flip beam

17-removes a 18-movable sleeve

Embodiment 1 makes lid 1 to upper overturning as Fig. 1, makes it to form the circular arc concave surface of declivity, and box body 3 is made outward flanging, makes it to form oblique circular arc concave surface, puts into sealing ring 2 between this two circular arcs concave surface.Equally, the bottom margin of box body 3 is also made the circular arc concave surface of declivity, this circular arc concave surface and lower floor's box body outward flanging form on tiltedly putting into sealing ring 2 between the circular arc concave surface.Then by handle one deck and the sealing ring of putting into down one deck down with quadrat method.Each that handle well stackedly put away and puts into locking frame 7, again locking beam 4 be placed on lid 1 above, make the upper end of locking frame 7 stick in the breach at locking beam 4 two ends fastening nut 5, the just whole multilayer lunch box of good seal.

Embodiment 2 is as Fig. 2, and except that n RunddichtringO and employing eccentric bushing locking device are outwards rolled and embedded in the edge of box body 3, other were identical with embodiment 1 basically.

Embodiment 3 is as Fig. 3, and except that the edge of box body 3 directly embeds sealing ring and adopts the eccentric wheel locking device, other is identical with embodiment 2.

Embodiment 4 is as Fig. 4, and except that sealing ring adopted the o RunddichtringO and employing eccentric disk locking device that has steel core, other were substantially the same manner as Example 1.

Embodiment 5 is as Fig. 5, and embodiment 6 is as Fig. 6, and except that adopting the tight device of flip beam locking device and handle lock, other are identical with embodiment 3 with embodiment 2.

The utility model compared with prior art has following advantage: can prevent effectively that vegetable soup from overflowing, collision, inversion situation are arranged in carrying exactly, the situation of rushing down can not take place to leak yet.

Claims

1, a kind of multilayer lunch box that has bale handle, feature of the present utility model be between lid and box body and upper strata box body and lower floor's box body between be provided with the plastic seal ring that prevents that vegetable soup etc. from overflowing.

2, multilayer lunch box according to claim 1 is characterized in that plastic seal ring adopts (cross section is for circular) or (cross section is a hat) of n type of o type.

3, multilayer lunch box according to claim 1 is characterized in that lid edge or box feather edge and box mouth edge make the circular arc concave surface tangent with plastic seal ring, or the box mouth is embedded in the plastic seal ring.

4, multilayer lunch box according to claim 1 is characterized in that being provided with the locking device that compresses each sealing ring.
