Description

Push-type exhaust cover

The invention relates to a cover body, in particular to a cover body for a disposable microwave lunch box and having an exhaust function.

With the development of economic construction, people's life rhythm is getting faster and faster, fast food has been widely accepted, and the use of disposable fast food packaging boxes is increasing. At present, the microwave lunch boxes on the market are made of plastic. The disposable lunch boxes are mainly PP polypropylene and PS polystyrene. They are non-toxic, tasteless and odorless. PP is soft. Generally, the PP temperature is -6. Degree to +120 degrees, so it is especially suitable for hot meals, can be heated in the microwave oven, please refer to the fifth figure, the conventional microwave box cover 30 directly has a U-shaped through hole 31 communicating with the outside to provide ventilation. However, since the ventilation method is directly connected to the outside, it is difficult to avoid the entry of dust or mosquitoes, and even the outer packaging material needs to be coated again to achieve a complete sealing state, and the outer packaging must be removed before the microwave to be microwaved, which is not only inconvenient to use. It is not environmentally friendly, so the conventional microwave lid is still necessary for improvement.

In view of this, how to eliminate the above-mentioned defects is the technical difficulty point that the inventor of the case wants to solve; however, the inventor of this case is based on years of experience in the relevant industry, after many years of painstaking research, trial improvement, finally Successfully developed the case and made the invention born to enhance the efficacy.

In view of the above disadvantages, the push-type venting cover of the present invention comprises: a first cover body provided with at least one through hole; and a second cover body with one side attached to one side of the through hole The second cover body has a bending line between the second cover body and the through hole, and the periphery of the second cover body is combined with the peripheral edge of the through hole by a point break line, and a convex surface is protruded from the top surface of the second cover body. When the latching portion is pressed down, the point of the second cover body is broken and broken into the through hole, and the top end of the latching portion is abutted against the other side of the through hole. The through hole communicates with the outside to achieve exhaust efficiency.

In order to facilitate the review of the contents of the present invention and the effects that can be achieved by the reviewing committee, the specific embodiments are listed with reference to the drawings, and the detailed description is as follows:

Referring to the first and second figures, the push-type venting cover 1 of the present invention includes a first cover 10 and a second cover 20, and the components are as follows:

The first cover 10 is provided with at least one through hole 11. In the embodiment, the through hole 11 is disposed in a recess 12, but is not limited thereto.

The second cover 20 has a side connected to one side of the through hole 11 and a bending line 21 between the second cover 20 and the through hole 11. The periphery of the second cover 20 is The point break line 22 is coupled to the periphery of the through hole 11, and a latching portion 23 is protruded from the top surface of the second cover body 20. Therefore, the second cover body 20 can close the through hole 11 to prevent entry of mosquitoes and dust.

The width of the second cover 20 is greater than the width of the latch portion 23, and the height of the latch portion 23 is greater than the width of the through hole 11.

Referring to the first to fourth figures, by pressing the latching portion 23, the point break 22 of the second cover 20 is broken and caught in the through hole 11, wherein the rear end of the latch portion 23 An arc portion 231 is disposed at the top of the through hole, and the arc portion is pressed against the peripheral edge of the through hole, and the latch portion 23 passes through the through hole 11 to make the top end of the latch portion 23 and the through hole 11 The other side of the top is abutted to allow the through hole 11 to communicate with the outside to achieve exhaust gas efficiency.

The detailed description of the present invention is intended to be illustrative of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention. In the scope of patents.
