TECHNICAL FIELD

[0001] The utility model relates to packing technical field, concretely relates to a packing container and two side open door formula top through cover. BACKGROUND

[0002] In the drinking water packing container, the most widely used cover is top through cover, and the most important feature of top through cover is simple structure and convenient production. The top through cover in the prior art generally sets a top through hole on the cover body, and the top through hole is sealed by a concave small disc, and the outer periphery of the small disc and the inner periphery of the top through hole are weakly connected. When the small disc is pressed by external force, the weakly connected part will break, so that the small disc and the cover body are separated, and then the top through hole is exposed to form a water taking opening. The external force of the small disc can be provided by the top through column of the water dispenser, or manually provided, so that the top through cover can meet the scenes of using with and without water dispenser. However, since the entire outer periphery of the small disc is connected with the cover body, and although it is a weak connection, it still needs to meet a certain connection strength, and the stress point when pressing is not directly applied to the weakly connected part. Therefore, when not using the water dispenser, it is difficult to open the top through cover by human force, and the size of the water taking opening after opening is consistent with the size of the top through hole. When a thinner water taking pipe is used, the larger water taking opening is easy to cause foreign matters to enter and pollute the water body. SUMMARY

[0003] In order to overcome the defects of the prior art, the utility model aims at providing a two-side open door type top through cover, which can be applied to different use scenes and meet different use requirements of users, and can facilitate opening of the water taking opening in different use scenes, and the size of the water taking opening after opening can be adapted to the size of the water taking pipe, so that foreign matters can be prevented from entering and polluting the water body.

[0004] To solve the above problems, the utility model adopts the following technical scheme: a two-side open door type top through cover, comprising a cover body and a door structure, the top of the cover body is provided with a top through hole, the door structure comprises two door pieces, the side of the two door pieces close to each other is connected with each other through a first weakly connected structure, and the side of the two door pieces away from each other is connected with the inner periphery of the top through hole through a second weakly connected structure to seal the top through hole, and the first weakly connected structure and the second weakly connected structure have an intersection.

When the water taking pipe is thin, the first weak connection structure will stop breaking when broken to a proper position, at this time, the size of the water taking opening is equivalent to the outer diameter of the thin water taking pipe, so as to adapt to the use of the thin water taking pipe, so as to avoid the situation that foreign matters enter the water body to pollute the water. When the water taking pipe is thick, the first weak connection structure will completely break, and will extend from the joint between the first weak connection structure and the second weak connection structure to the second weak connection structure, so that the second weak connection structure continues to break, thereby forming a larger water taking opening, at this time, the size of the water taking opening is equivalent to the outer diameter of the thick water taking pipe, so as to adapt to the use of the thick water taking pipe. When the water is taken by using the water dispenser and other equipment, the second weak connection structure will break to the maximum position, at this time, the size of the water taking opening is equivalent to the outer diameter of the top-penetrating column of the water dispenser and other equipment, and is equivalent to the inner diameter of the top-penetrating hole, so as to adapt to the use of the top-penetrating column of the water dispenser and other equipment. Therefore, the top-penetrating cover can be applied to different use scenes, and meets different use requirements of users, and in different use scenes, the water taking opening can be easily opened, and the size of the opened water taking opening can be adapted to the size of the water taking pipe, so as to avoid the situation that foreign matters enter the water body to pollute the water.

[0018] BRIEF DESCRIPTION OF DRAWINGS: 100 cover body, 200 door structure, 210 door piece, 220 first weak connection structure, 230 second weak connection structure, 240 door handle, 250 reinforcing rib, 300 top-penetrating column. DETAILED DESCRIPTION

[0019] The embodiments of the present application will be described in detail below, with reference to the accompanying drawings. Figures 1 to 4 The embodiments of the present application provide a two-side opening door type top-penetrating cover, which comprises a cover body 100 and a door structure 200. The top of the cover body 100 is provided with a top-penetrating hole. The door structure 200 comprises two door pieces 210. The two door pieces 210 are connected to each other through a first weak connection structure 220 on the side close to each other. The two door pieces 210 are connected to the inner periphery of the top-penetrating hole through a second weak connection structure 230 on the side away from each other, so as to seal the top-penetrating hole. The first weak connection structure 220 and the second weak connection structure 230 have an intersection. It can be understood that the first weak connection structure 220 and the second weak connection structure 230 described in the present application have similar structure and principle of action to the weak connection structure in the existing top-penetrating cover. They are a structure integrally formed when the mold is opened. The material thickness is relatively thin. The structure will not be broken in the packaging and transportation process, so as to seal the top-penetrating hole, so as to protect the liquid in the packaging container. When a certain size of external force is applied, the structure will be broken, so as to facilitate the taking out of the liquid in the packaging container.

[0020] The packaging container described in the present application can be a drinking water bucket, a drinking water bottle or the like.

[0021] The door structure 200 of the top-piercing cover includes two door pieces 210. When the door structure 200 is pressed, the first weak connection structure 220 between the two door pieces 210 will be directly stressed, thereby breaking to form a water outlet, so that the top-piercing cover is easy to be pierced when not used on a water dispenser. When the water pipe is thin, the first weak connection structure 220 will stop breaking at a proper position, at which the size of the water outlet is equivalent to the outer diameter of the thin water pipe, so as to adapt to the use of the thin water pipe, so as to avoid the situation that a larger water outlet is formed and foreign matters enter the water body to pollute the water. When the water pipe is thick, the first weak connection structure 220 will completely break and extend from the intersection between the first weak connection structure 220 and the second weak connection structure 230 to the second weak connection structure 230, so that the second weak connection structure 230 continues to break, thereby forming a larger water outlet, at which the size of the water outlet is equivalent to the outer diameter of the thick water pipe, so as to adapt to the use of the thick water pipe. When the water is taken by using a water dispenser or the like, the second weak connection structure 230 will break to the maximum position, at which the size of the water outlet is equivalent to the outer diameter of the top-piercing column 300 of the water dispenser or the like, and is equivalent to the inner diameter of the top-piercing hole, so as to adapt to the use of the top-piercing column 300 of the water dispenser or the like. Therefore, the top-piercing cover can be applied to different use scenarios and meet different use requirements of users, and in different use scenarios, the water outlet can be easily opened, and the size of the opened water outlet can be adapted to the size of the water pipe, so as to avoid the situation that foreign matters enter the water body to pollute the water.

[0022] Further, referring to Figure 1 and Figure 2 , the door handle 240 is arranged on the side of the two door pieces 210 close to each other, and the top surface of the door handle 240 is an arc surface. When the door structure 200 is subjected to an external force, the structure of the door handle 240 can make the stress of the door structure 200 more concentrated on the position of the first weak connection structure 220, so that the first weak connection structure 220 is more easily broken, and the door structure 200 will first break at the position of the door handle 240, that is, first break at the middle position of the first weak connection structure 220, and then extend in two directions, so as to not only make the first weak connection structure 220 easily broken, but also better adapt the size of the water outlet to the size of the water pipe.

[0023] Further, referring to Figure 3 and Figure 4, two door pieces 210 are provided with reinforcing ribs 250 on the side away from each other and the cover 100, and the reinforcing ribs 250 are located on the inner side of the cover 100. When the water taking pipe is thin, the second weak connection structure 230 is not broken, so the two door pieces 210 can still be connected with the inner periphery of the top perforation, and after the water taking pipe is removed, the first weak connection structure 220 can gradually close under the self-recovery of the material, so as to close the door structure 200 to prevent foreign matters from entering. When the water taking pipe is thick, the second weak connection structure 230 will be broken, at this time, the reinforcing ribs 250 can make the door pieces 210 remain connected with the cover 100, so as to prevent the door pieces 210 from falling into the packaging container, and also avoid that the water taking opening is directly exposed after the water taking pipe is removed, so as to prevent foreign matters from entering. In addition, after the water taking pipe is removed, the reinforcing ribs 250 can also generate a reaction force to push the two door pieces 210 back, so as to form a kind of virtual closing state to prevent foreign matters from entering. Further, referring to Figure 2 , the whole door structure 200 is an arc surface structure concave towards the bottom, and no side wall is formed between the outer periphery of the door structure 200 and the cover 100, but the door structure 200 is directly formed from the top surface of the cover 100 and concave towards the bottom, so that the door pieces 210 of this kind of structure can rebound more easily to form a closing state after the water taking pipe is removed.

[0024] Further, the connecting line between the two reinforcing ribs 250 is perpendicular to the extension direction of the first weak connection structure 220, the connecting line between the two reinforcing ribs 250 is the X direction, the extension direction of the first weak connection structure 220 is the Y direction, the intersection of the X direction and the Y direction is O, the intersection between the first weak connection structure 220 and the second weak connection structure 230 is A, and the position of the reinforcing rib 250 is B. When the door structure 200 is stressed, the crack will first break from the O point, then extend along the Y direction, and after extending to the A point, continue to extend along the circular arc S until extending to the B point, and then stop extending. Therefore, the connecting line between the two reinforcing ribs 250 is perpendicular to the extension direction of the first weak connection structure 220, so that the crack extends symmetrically and orderly, and the water taking opening formed can better adapt to the water taking pipe.

[0025] The embodiment of the utility model also provides a packaging container, which can be a drinking water bucket, a drinking water bottle or the like structure, and the packaging container comprises the above-mentioned two-side opening door type top-penetrating cover, so that it has all the beneficial effects brought by the above-mentioned two-side opening door type top-penetrating cover. Further, in the packaging container, the top-penetrating cover can be buckled to the mouth of the packaging container or be screwed to the mouth of the packaging container.
