Abstract

The utility model relates to a leakproof lunch-box which is provided with lockup devices. The utility model overcomes the defects that products of the prior art can not play the role of leak proofing owing to have no lockup device, and dangers are easy to happen in the sealing state when the liquid state food is being heated and the box cover is lidded on firmly. The leakproof lunch-box with lockup device is characterized in that a controller used to lockup is arranged on the box body, and a groove is arranged on the combination between the interior of the box cover and a back cut of the box body. Elastic sealing elements are arranged in the groove, and a bayonet which is used for the locating of a tongue is arranged on side walls of both sides of the box cover. The leakproof lunch-box with lockup device can achieve functions of sealing and leak proofing, which can also make the lunch-box under a state of non-sealing. The utility model has the advantages of high safety and simple structure.

Description

Leakproof lunch-box with lockup device

The utility model belongs to a kind of lunch box, particularly a kind of leakproof lunch box with locking device.

In order to prevent the leakage of food in the lunch box, the structure of taking potted component that has in the prior art, as the patent No. is the leakproof lunch box of " 87211758 ", it is at the box body of ordinary lunch-box position suitable for reading an elastic sealing elements to be installed, the extruding force that utilization acts on the elastic sealing elements stops food leakage in the box, owing to only depending on this extruding force not have locking device, when making lunch box inclination or upset carrying lunch box, aqueous liquid foodstuff very easily overflows, and does not in fact have the leakproof effect.In addition, when the tight lunch box of lid, this lunch box is in sealing state all the time, and when the heating aqueous liquid foodstuff, the lunch box internal pressure increases easy jack-up cover of the lunch box gradually and causes danger.

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of food that prevents to overflow, the safe and reliable leakproof lunch box with locking device.

The utility model is achieved in that it has a box body and lid, the block tongue that has locking effect is installed on box body, there is a groove inside and box body junction suitable for reading at lid, in this groove, elastic sealing elements is housed, on the side walls of lid, have the bayonet socket that makes block tongue location, during use, cover lid and compress, be about to block tongue and be stuck in the bayonet socket on the lid, can realize locking and the function of sealed against leakage.

The utility model is elaborated and embodiment is provided below in conjunction with accompanying drawing:

Fig. 1 is a front view of the present utility model;

Fig. 2 is Figure 1A-A cutaway view;

Fig. 3 is the 1 part enlarged drawing of Fig. 2;

Fig. 4 is a vertical view of the present utility model;

As shown in drawings, the utility model has a box body 2, on the side walls of box body 2, be fixed with the block tongue of making of elastomeric material with locking effect 4 with rivet, stagger mutually in the position of said block tongue 4 on relative two sides on the box body 2, have square hole 7 at the middle part of block tongue 4, position in block tongue 4 upper aperture 7 both sides is processed with a pair of through hole, handle 5 is installed in this through hole, there is a boss 5b at the position of said handle 5 corresponding square holes 7, the anti-scald sleeve pipe of making of nonmetallic materials (as bakelite) 6 also is installed on handle 5, a lid 1 is arranged on box body 2, stamp out a groove 1a in the bottom surface of said lid 1 and the junction suitable for reading of box body 2, elastic sealing elements 3 is housed in groove 1a, and the position corresponding to block tongue 4 on the sidewall of lid 1 has the bayonet socket 8 that makes block tongue 4 location.

During use, according to making bayonet socket 8 and block tongue 4 relative directions cover lid 1 and compressing, block tongue 4 is stuck on the bayonet socket 8 lid 1 is blocked, because elastic sealing elements 3 produces elastic deformations, lid 1 is tightly contacted with junction, box body 2 upper edge reach the sealed against leakage effect.When wanting to open or taking off lid 1, handle 5 with box body 2 both sides upwards turns to horizontal level simultaneously, at this moment boss 5b is by square hole 7 and withstand on the sidewall of box body 2, and the top that makes block tongue 4 is by jack-up and then make block tongue 4 break away from square holes 7, and just can open the lid 1 this moment.When food does not need to seal in the box body 2, can cover lid 1 by the direction that bayonet socket 8 and block tongue 4 are staggered, at this moment block tongue 4 is inoperative, elastic sealing elements 3 essentially no elastic deformations, the utility model just is in the non-tight state.When box body 2 and lid 1 because of box body 2 in food when being in high temperature and scalding one's hand, handle 5 is upwards turned to vertical, just can play anti-scald effect.

The utility model has the advantage of simple in structurely, can realize the effect of sealed against leakage, also can make as required the utility model be in the non-tight state, owing at handle anti-scald sleeve pipe is housed, can also play anti-scald effect, thus safe and reliable.
