Abstract

The utility model relates to a sealing-type lunch-box, which belongs to domestic articles. The sealing-type lunch-box is characterized in that the rigidity framework and elastic buckles are adopted. The utility model has the advantages of high rigidity, high reliability, simple manufacturing process, convenient operation and high durability, which is used for carrying dishes with dripping. No matter what states the lunch-box is in, the sealing-type lunch-box can ensure the excellent sealing property.

Description

Sealing-type lunch-box

The utility model relates to the improvement of Dinner pail.

At present commercially available various Dinner pails are in carrying the food process; In the box the soup juice in the dish of filling a bowl with rice spill the clothing etc. of making dirty often, very troubling.

The purpose of this utility model is to overcome the deficiency of now selling lunch box, provides a kind of sealing property not spill the sealed Dinner pail of soup juice reliably.

The utility model is mainly by lid 1, sealing ring 2, and box body 3, rigid backbone 4 and Elastic buckle 6 are formed.One of its characteristics are to have placed rigid backbone 4 in the crimping of lid and box body, have thoroughly solved known sealing class Dinner pail because the very thin rigidity deficiency that causes of material is yielding, and sealing is difficult for the key issue of assurance.Two of its characteristics are to have designed a kind of Elastic buckle as locking device.Not only simplified this class device, and used not only convenient but also reliable.The different limit degree of lip-rounding formulas and the sealing ring of corresponding different section shape have been adopted; To adapt to the requirement of various processes.Sealing ring 2 usefulness meet rubber or other plastic material of food hygiene requirement to be made, and its section configuration can be the O type, and it is compound that rectangle or the two combine.Also can adopt other various section configurations.

The utility model is selecting for use sheet material manufacturing thicker or good rigidly can place rigid backbone 4.

Below in conjunction with embodiment the utility model is done further specific description.

Accompanying drawing of the present utility model has:

Number description:

1, lid 4, rigid backbone 7, buckle sliding sleeve

2, sealing ring 5, snap seats 8, buckle are removed handle

3, box body 6, Elastic buckle 9, little axle

10, common buckle

Embodiment 1 is as Fig. 1: O RunddichtringO 2 is enclosed within on the edge of lid 1 arc.The spy has placed a rigid backbone 4 in the edge crimping of box body 3, has solved very poorly, yielding because of the thin rigidity of material in the past, thereby is difficult for the difficult problem of sealing.The external diameter of sealing ring 2 is made the internal diameter greater than box body 3, cover lid 1 after, the inboard crush seal circle 2 in the edge of its curved edge and box body 3 makes it to produce strain, has so just reached the purpose that seals.5 of snap seats are welded on the box body 3 and Elastic buckle 6 are housed.It is big that this Elastic buckle has elasticity, and reliable lock is simple in structure, and is easy to use, is the utility model initiative.Cover behind the lid 1 thereon, both made that lid 1 can not fall down when on the way running into the situation of colliding with yet this Elastic buckle button.The designed hermetically-sealed construction of this example because the bounce effect of sealing ring 2, also can any locking or attachment device lid 1 can oneself not hold yet, and still have reliable sealing performance.

Embodiment 2 is as Fig. 2: this routine lid 1 and box body 3 place lid 1 and contacted position, box body 3 edges.Common buckle 10 is buckled in above the edge of lid 1; Move buckle downwards and remove after 8 and both produced a tightening force, make the purpose that had both realized sealing after the lid compresses seal 2.

Embodiment 3 is as Fig. 3: this example combines O type and rectangle sealing ring and forms a kind of compound sealing ring, has the dual-seal effect, also is well suited for the container that other need seal except being used for lunch box.The sealing ring 2 that this is compound is enclosed within the outside, edge of lid 1.Be provided with rigid backbone 4 in the crimping of box body 3.Angie type in make at the elasticity position of Elastic buckle 6 is built lid 1, and buckling both can be with the lunch box good seal behind the Elastic buckle 6.

Embodiment 4 is as Fig. 4: be equipped with rigid backbone 4 in the edge crimping of this routine lid 1 and box body 3.The form of Elastic buckle 6 changes to some extent, and the elasticity position has been located at bottom, bigger lunch box can make than broad as the Elastic buckle of A to two snap seats of be shown with.Also can make the Elastic buckle of other various sizes and pattern as required.The edge section of lid 1 is made flute profile, and compound sealing ring 2 is placed in the groove, covers on the edge that Elastic buckle 6 is buckled in behind the lid 1 lid 1 and has both sealed lunch box rapidly.

Claims

1, a kind of sealed Dinner pail, mainly by lid 1, sealing ring 2, box body 3, rigid backbone 4 and Elastic buckle 6 formed, and it is characterized in that being placed with rigid backbone 4 and making locking device with Elastic buckle 6 in the crimping of lid 1 and box body 3.

2, Dinner pail according to claim 1 is characterized in that the elasticity position of Elastic buckle 6 can be arranged on different positions, and its form and size can be made various as required.

3, Dinner pail according to claim 1 is characterized in that the sealing ring section can be a different shape.

4, if Dinner pail according to claim 1 is characterized in that can be without rigid backbone 4 when making of plate thicker or good rigidly.
