Description

TECHNICAL FIELD

The present invention relates to the technical field of pizza boxes, and particularly relates to a heat insulation pizza box.

BACKGROUND

Pizza, also known as pizza pie, pisa, pisa pie, pizza cake and pizza pancake, is a food originated from Italy.

When eating pizza, people sometimes need to store the rest pizza, to store the rest pizza into a refrigerator or heat the rest pizza in a microwave oven before eating. At present, there are paper or plastic disposable pizza packaging boxes on the market. It is inconvenient for storing the rest pizza. Firstly, when the rest pizza is stored in a refrigerator, the rest pizza is poor in sealing performance and is prone to taint of odor with other foods in the refrigerator. Secondly, the rest pizza has high temperature after heated in a microwave oven, and the existing pizza box is easy to scald the hand and inconvenient to take up and carry.

Therefore, with respect to the above problems in the prior art, the technical problem to be urgently solved by those skilled in the art is to provide a pizza box with sealing and heat insulation functions.

The present invention has the beneficial effects that: the box body with the triangular sector structure is used for storing a plurality of pizza triangular slices; the top cover is covered on the open end of the box body and a contact surface has a seal structure to improve the sealing effect for storage of the pizza box. The top cover and the box body are opened or closed by the claw buckles and the clamping flange; and the box body and the top cover are wrapped with the heat insulation layers, so that the pizza box has a good heat insulation effect, and achieves heat insulation and anti-scalding effects when a heated pizza is stored.

On the basis of the above technical solution, the present invention can also be improved as follows.

Further, the heat insulation layers comprise a first heat insulation layer and a second heat insulation layer; the first heat insulation layer comprises a horizontal first wrapping part and a second wrapping part extending upward perpendicular to the edge of the first wrapping part; the first wrapping part and the second wrapping part define a first groove fitted with the bottom of the box body and wrapped; the second heat insulation layer comprises a vertical third wrapping part and a fourth wrapping part extending horizontally perpendicular to the edge of the third wrapping part; and the third wrapping part and the fourth wrapping part define a second groove fitted with the edge of the top cover and wrapped.

The above further solution has the following beneficial effects: when a user takes up the pizza box, hands usually touch the bottom of the pizza box and the edge of the top cover. The heat insulation layers are arranged at the corresponding parts to achieve the heat insulation and anti-scalding effects.

Further, the side wall of the top cover protrudes outwards to form a raised clamping structure; the raised clamping structure comprises a first bump, a second bump and a hinging shaft; the first bump and the second bump are arranged oppositely; the hinging shaft is connected to the opposite side of the first bump and the second bump; and the claw buckles are hinged with the hinging shaft.

The above further solution has the following beneficial effects: the claw buckles rotate with the hinging shaft as a center to realize the opening or closing of the top cover and the box body.

Further, each claw buckle comprises a hinging part, a buckling part and the clamping plate; the hinging part is a ring structure with a section greater than ½ circle and is hinged with the hinging shaft; one end of the hinging part away from the hinging shaft is integrally connected with the buckling part; the outer side wall of the buckling part is inclined downwards away from the box body; the clamping plate is perpendicular to the inner side wall of the buckling part, and an upper end surface is clamped with the lower end surface of the clamping flange.

The above further solution has the following beneficial effects: the outer side wall of the buckling part is inclined to the outer side at a certain angle, which is convenient for the user to apply force on the buckling part to open or close the top cover.

Further, the upper end surface of the top cover is provided with a heat dissipation hole which penetrates through the top cover and a heat dissipation cover for covering the heat dissipation hole; the heat dissipation cover comprises a plug and a clamping ring; an outer ring of the clamping ring is adaptively clamped with the heat dissipation hole; the plug is in T type; the outer side end of a transverse plate is rotatably connected with the clamping ring, and a vertical plate is an inserting block which extends downwards; and the inserting block is adapted to and slidably inserted with an inner ring of the clamping ring.

The above further solution has the following beneficial effects: when the pizza in the pizza box needs heat dissipation, the user only needs to apply upward force on the heat dissipation cover, the plug slides out from the heat dissipation hole and the interior of the box body is communicated with the outside through the heat dissipation hole for heat dissipation.

Further, the top cover is made of high borosilicate glass material; and the box body is made of high borosilicate glass material or stainless steel material.

The above further solution has the following beneficial effects: when the top cover and the box body are made of the high borosilicate glass material, the pizza box can be heated directly in a microwave oven or an oven; the link of putting the pizza into a baking tray is eliminated in the process of heating the pizza; and thus there is no trouble of cleaning the baking tray for the user. Because of the heat insulation and anti-scalding effects of the heat insulation layers, the user can take up and carry the pizza immediately after the pizza is heated in the oven.

Further, the side wall of the box body is hinged with a bracket handle, and the bracket handle can be rotated upward and buckled on the top cover.

The above further solution has the following beneficial effects: it is convenient to take up and carry the pizza box through the bracket handle. When placed, the bracket handle can be rotated and buckled on the top end of the top cover to reduce space occupation.

Further, the lower end surface of the top cover is sunk inwards to form a sealing groove; and a sealing ring is installed in the sealing groove and is hermetically abutted against the upper end surface of the clamping flange.

The above further solution has the following beneficial effects: the top cover and the box body are sealed by the sealing ring, which has a good sealing effect.
