Description

The clamping structure of convenient mess tin

The utility model relates to the structure technology of convenient mess tin, is a kind of clamping structure of convenient mess tin, refers to a kind of structure that fixes mutually by the volume round mouth edge of lid positioning convex point and box body especially.

The situation that the affluence though the modern lives, breakfast, lunch and dinner do not continue is fewer and feweri,, even today that high-tech is assumed command, catering trade remains unchanged and develops vibrantly, especially the place contested by all strategists of catering trade especially in shopping centre and the school district.And for staying the teachers and students of middle and primary schools that have a dinner in the school, and the employee of large-scale organ, if not tiffin,, cordially invite the service of the cook and cook the meal exactly from having central authorities meal kitchen by outer braised dealer, it serves to show the flourishing scene of catering trade today; Relatively, the convenient mess tin that the consumer uses also has significant progress, convenient mess tin on the market can see that lid and box body have the form of interior convex wall rib now, take the packing dish in order to form groove, and, lid is also darker than before, makes can place tablewares such as bowls and chopsticks, soup bowl in the lunch box, and is very convenient really.But the box and the box body of existing convenient mess tin are still continued to use the purpose that two buckle ears reach fixing, and buckle ear formula clamping structure has following shortcoming: 1, shelter evil people and countenance evil practices easily near the buckle ear, but be difficult to clean.2, its processing and material cost are difficult to reduce all the time.3, service life is not long.

Main purpose of the present utility model is to propose a kind of clamping structure of convenient mess tin, and this structure is by the fixing of the volume round mouth edge of several positioning convex points of lid and box body design, make the convenient mess tin lid fixing, to start action more simple and easy.

Secondary objective of the present utility model is to propose a kind of clamping structure of convenient mess tin, this structure is by the fixing design of the volume round mouth edge of several positioning convex points of lid and box body, improve and to commonly use buckle ear formula structure and be easy to accumulate dirt, clean and be difficult for, and service life short problem.

Another purpose of the present utility model is to propose a kind of clamping structure of convenient mess tin, and this structure is saved material and the processing cost of commonly using buckle ear formula structure by the fixing design of the volume round mouth edge of several positioning convex points of lid and box body.

Main technical schemes of the present utility model and principal character are: the clamping structure of this convenient mess tin, its lunch box mainly are to be covered up and down by a lid and a box body to form; It is characterized in that:

This box body has the peristoma of outside volume circle, and be slightly larger than the circular section diametrical position of its box body peristoma apart from its top with respect to the lid inner side edge, inwardly dash and establish several positioning convex points, but the application of force is covered on lid on the box body whereby, the inboard top that makes lid is by terminating in the peristoma top side of box body, several positioning convex points on the lid then are fastened in the peristoma bottom side of box body, and then make the clamping structure of convenient mess tin can reach practical effects such as operation is simple and easy, long service life, low cost.Wherein, this lid is to have enough degree of depth, so that convenient mess tin can ccontaining bowls and chopsticks, tableware such as soupspoon, and its lid side edge bottom section is stepped, forms the edge that connects of an evagination, and this connects on the edge in the circular section diametrical position that is slightly larger than the box body peristoma apart from its top, inwardly dash and establish several positioning convex points, but the application of force is covered on lid on the box body whereby, makes inboard top that lid connects edge by terminating in the peristoma top side of box body, and lid connects the peristoma bottom side that several positioning convex points on the edge then are fastened in box body.Wherein this lid or box body are the form with interior convex wall rib, are used to form groove and split dish.Wherein this convenient mess tin is rectangular or circular.This lid side is to establishing two or more positioning convex points.

Major advantage of the present utility model be to make the convenient mess tin lid fixing, to start action more simple and easy, improve and to commonly use buckle ear formula structure and be easy to accumulate dirt, clean and be difficult for, and service life short problem, the material and the processing cost of buckle ear formula structure commonly used in saving, reaches the low effect of easy cleaning, long service life and production cost.

The figure number explanation: 10 lids, 11 positioning convex points 12 connect edge 20 box bodys 21 peristomas 30 wall ribs

31 grooves, 40 vegetable dish

From Fig. 1--as can be known, the clamping structure of convenient mess tin of the present utility model, its lunch box mainly are to be covered up and down by a lid 10 and a box body 20 to form shown in-the 2A; It is characterized in that:

This box body 20 has the peristoma 21 of outside volume circle, and be slightly larger than the circular section diametrical position of its box body 20 peristomas 21 apart from its top with respect to lid 10 inner side edges, inwardly dash and establish several positioning convex points 11, but the application of force is covered on lid 10 on the box body 20 whereby, make peristoma 21 top sides of inboard top by terminating in box body 20 of lid 10, several positioning convex points 11 on the lid 10 then are fastened in peristoma 21 bottom sides of box body 20, because its processing is very easy, therefore its cost is very cheap, and the clamping structure of this convenient mess tin is simplified many than the buckle ear commonly used, and is not only more simple and easy and more can significantly prolong its service life in the operation.

As Fig. 3--shown in-5, be to be applied in the rectangle lid 10 of another kind of pattern for the utility model, this lid 10 is to have enough degree of depth, so that convenient mess tin can ccontaining bowls and chopsticks, tablewares such as soupspoon, and its lid 10 side edge bottom sections are stepped, what form an evagination connects edge 12, and this connects on the edge 12 in the circular section diametrical position that is slightly larger than box body 20 peristomas 21 apart from its top, inwardly dash and establish several positioning convex points 11, but the application of force is covered on lid 10 on the box body 20 whereby, make lid 10 connect peristoma 21 top sides of inboard top by terminating in box body 20 of edge 12, lid 10 connects peristoma 21 bottom sides that several positioning convex points 11 on the edge 12 then are fastened in box body 20.

And be different from the pattern of aforementioned pair of positioning convex point 11, and the utility model also can be made as four positioning convex points 11 of symmetry, as shown in Figure 6, certainly, considers its firm degree, and the number of positioning convex point 11 can optionally increase; And in Fig. 7--shown in-10, be to be applied to lid 10 or box body 20 has the pattern of interior convex wall rib 30, be used to form groove 31 and split dish;

As Figure 11--shown in-14, be to be applied to circular convenient mess tin, wherein, this lid 10 or box body 20 are for having the form of interior convex wall rib 30, perhaps have a vegetable dish 40, and the number of its positioning convex point 11 can be the symmetry 3 points, four point locations, perhaps 2 points, more than all can more than 4 o'clock.
