TECHNICAL FIELD
[0001] The utility model relates to packing box cover field, concretely relates to disposable packing box cover. BACKGROUND
[0002] With the quickening of people's life rhythm, the take-out quantity is also more and more big, and the consumer puts forward more requirements to the quality and portability of tableware. When the existing packing box is sealed with food with a large amount of soup, generally, multiple layers of preservative films are wound between the box cover and the box body, although this can prevent the soup from spilling to a certain extent. But in this case, the inside of the take-out lunch box is often deformed due to heating or bulging due to poor exhaust, and after the lunch box is deformed, the preservative film can hardly guarantee the sealing effect. SUMMARY
[0003] In view of the deficiencies existing in the prior art, the utility model aims at providing disposable packing box cover, the structure design is reasonable, it is used on disposable packing box, can prevent the soup from leaking, and has exhaust effect, and the practicality is strong.
[0004] In order to realize the above-mentioned purpose, the utility model is through the following technical scheme to realize: disposable packing box cover, including box cover body, flow guide groove, flexible connecting belt, sealing cover, exhaust hole, outer air outlet and water baffle, one corner of the box cover body is provided with the flow guide groove, the exhaust hole is arranged in the flow guide groove, the edge of the box cover body outside the flow guide groove is connected with the flexible connecting belt, the flexible connecting belt is connected with the sealing cover, the outer air outlet is arranged on the sealing cover, the sealing cover is buckled with the upper edge of the flow guide groove, the exhaust hole and the outer air outlet are staggered, and the outer side of the exhaust hole is further provided with the water baffle.
[0005] As preferred, the lower edge of the box cover body is a sealing buckle connected with the box body.
[0006] As preferred, the shape of the flexible connecting belt is consistent with the edge of the box cover body.
[0007] The utility model has the advantages of reasonable structure design, exhaust through the exhaust hole, and water baffle, which can block the soup and prevent the soup from leaking, convenient and reliable to use, and strong practicality. BRIEF DESCRIPTION OF DRAWINGS
[0008] The utility model will be described in detail in combination with the drawings and specific embodiments;
[0009] Fig. 1 It is the structural schematic diagram of the utility model;
[0010] Fig. 2 It is the sealing cover opening diagram of the utility model. DETAILED DESCRIPTION
[0011] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.
[0012] With reference to Figs. 1-2 The utility model discloses a disposable packing box cover, including box cover body 1, diversion groove 2, flexible connecting band 3, sealing cover 4, exhaust hole 5, outer air hole 6 and water baffle 7, diversion groove 2 is arranged on one corner of box cover body 1, exhaust hole 5 is arranged in diversion groove 2, the edge of box cover body 1 on the outside of diversion groove 2 is connected with flexible connecting band 3, flexible connecting band 3 is connected with sealing cover 4, outer air hole 6 is arranged on sealing cover 4, sealing cover 4 is buckled with the upper edge of diversion groove 2, exhaust hole 5 and outer air hole 6 are staggered arrangement, the outside of exhaust hole 5 is also provided with water baffle 7.
[0013] It is worth noting that the lower edge of the box cover body 1 is a sealing buckle connected to the box body.
[0014] In addition, the shape of the flexible connecting band 3 is consistent with the edge of the box cover body 1.
[0015] The diversion groove 2 provided on the box cover body 1 of the present embodiment is used to collect the liquid (such as soup) or steam condensate water overflowing from the box, and the exhaust hole 5 provided in the diversion groove 2 is used to exhaust the steam in the box, so as to avoid the box cover from bulging or exploding due to excessive pressure in the box. The flexible connecting band 3 connects the box cover body 1 and the sealing cover 4, so that the sealing cover 4 can be flexibly opened and closed. The sealing cover 4 is used to cover the diversion groove 2 to prevent external dust or contaminants from entering the exhaust hole 5. The outer air hole 6 provided on the sealing cover 4 is staggered with the exhaust hole 5, which ensures that the steam can be smoothly exhausted, while avoiding direct overflow of liquid. The water baffle 7 is provided on the outside of the exhaust hole 5 to block the liquid from overflowing from the exhaust hole 5, further improving the leakage prevention performance. The sealing buckle on the lower edge of the box cover body 1 is tightly connected with the box body, ensuring the sealing performance between the box cover and the box body, and preventing liquid from spilling.
[0016] The specific embodiment can effectively collect and block the overflowing liquid by the design of the flow guide groove 2 and the water baffle 7, and prevent the soup from spilling. The sealing fastener further enhances the sealing between the box cover and the box body, ensuring that the liquid does not overflow from the edge. The staggered arrangement of the exhaust hole 5 and the outlet hole 6 ensures that the steam in the box can be smoothly discharged, avoiding the box cover from bulging or exploding due to excessive pressure in the box. The design of the flow guide groove 2 can also guide the condensed water to a specific area, avoiding the condensed water from overflowing from the exhaust hole 5. The flexible connecting band 3 allows the sealing cover 4 to be flexibly opened and closed, facilitating user operation, while ensuring that the sealing cover 4 can tightly cover the flow guide groove 2. The sealing cover 4 can effectively prevent external dust or contaminants from entering the exhaust hole 5, ensuring the hygiene and safety of food.
