Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to fig. 3, it is a schematic structural diagram of the simple drainage type paper cover provided by the present invention. The simple drainage type paper cover is used for covering a container 10. The container 10 comprises a container mouth 11 and a circular bead 12 arranged on the edge of the container mouth 11. The container 10 may be a paper container such as a paper bowl or a paper cup, which is a prior art and will not be described herein. The circular bead 12 is also the most common configuration of the container 10 and will not be described in detail herein.
The simple drainage type paper cover comprises a cover bottom 21, a cover edge 22 connected with the cover bottom 21, and a drainage ring 23 arranged on the cover bottom 21 and positioned on the opposite side of the cover edge 22.
The lid bottom 21 may be made of a single layer of paper, which should be food grade paper, and may have a grammage of between 190 and 380 grams.
The lid flange 22 structurally includes a middle layer 221, and two covering layers 222 respectively adhered to both sides of the middle layer 221. The intermediate layer 221 is integrally formed with the cover bottom 21 to connect the cover bottom 21 and the cover rim 22 together. Two layers of the coating layers 222 are respectively disposed on two sides of the middle layer 221, and preferably, the two layers of the coating layers 222 are integrally formed to coat the middle layer 221, so as to coat three outer sidewalls of the middle layer 221. The cover 222 may be made of the same paper as the cover bottom 21. The lid flange 22 functionally includes a snap-in portion 223 and a lead-in portion 224 connected to the snap-in portion 223. One end of the clamping portion 223 is directly connected to the cover bottom 21 and is used for clamping the circular bead 12 of the container 10, and the specific working principle will be described in detail below. The lead-in portion 224 is used to insert the circular bead 12 of the container 10 into the snap-in portion 223. The angle between the extending direction of the lead-in portion 224 and the central axis of the cover bottom 21 is between 0 degree and 12 degrees. In this embodiment, the extending direction of the introducing portion 224 is parallel to the central axis of the cover bottom 21, i.e. 0 degree. At the same time, the maximum diameter of the lead-in 224 is smaller than the circular bead 12 of the container. Because the cross section of the circular bead 12 of the container 10 is circular, when the container mouth 11 is buckled into the clamping portion 223, firstly the introduction portion 223 is spread under the effect of the circular bead 12 of the container 10, then the circular bead 12 of the container 10 is clamped between the clamping portion 223 and the cover bottom 21, and finally the introduction portion 223 retracts towards the central axis of the cover bottom 21, so that the paper cover 100 and the container 10 are clamped. In order to cover the circular bead 12 of the container, the contour line of the locking portion 223 is an arc shape in a cross section along the central axis of the lid bottom 21, and the central angle of the arc shape is between 90 degrees and 120 degrees. Meanwhile, the arc chord of the contour line of the clamping part 223 on the section along the central axis of the cover bottom 21 is parallel to the central axis of the cover bottom 21. In order to allow the insertion portion 224 to catch the circular bead 12, the arc-shaped chord of the contour line of the snap-in portions 223 is arranged parallel to and spaced apart from the extending direction of the insertion portion 224 in a cross section along the central axis of the cover bottom 21, and therefore the distance between the two snap-in portions 223 is equal to the maximum distance between the circular beads 12 in a cross section along the central axis of the cover bottom 21.
The drainage ring 23 serves for guiding the flow and comprises a connecting edge 231 connected to the lid edge 22 and a drainage bead 232 arranged at the free end of the connecting edge 231. The connecting edge 231 is connected to the covering layer 222, so that the drainage ring 23 is disposed on the cover bottom 21. Specifically, the connecting edge 231 is integrally formed with the covering layer 222. For the purpose of guiding the flow, an included angle between the extending direction of the connecting edge 231 and the central axis of the cover bottom 21 is an acute angle, and specifically, an included angle between the extending direction of the connecting edge 231 and the central axis of the cover bottom 21 is between 10 degrees and 20 degrees. The drainage curling edge 232 is formed by curling the free edge of the connecting edge 231, and the method for rolling the drainage curling edge 232 is the prior art and is not described herein again.
As shown in fig. 4, the simple drainage paper cover further includes a spout 24 disposed on the cover bottom 21. The cannula port 24 is one of a cross-shaped notch, a circular through hole and a hexagonal through hole, and is used for inserting a suction tube. In this embodiment, the cannula port 24 is a circular through hole.
As shown in fig. 5, the simple drainage type paper cap further includes a drinking hole 25 formed in the cap bottom 21. The drinking spout 25 may be oval.
Compared with the prior art, the simple drainage type paper cover provided by the utility model can be directly covered or buckled on the container mouth 11 of the container 10, and because one end of the clamping part 223 of the cover rim 22 is directly connected with the cover bottom 21, when the paper cover is buckled on the container mouth 11 of the container 10, the circular bead 12 of the container 10 can be clamped between the clamping part 223 and the cover bottom 21 without moving, meanwhile, because the maximum diameter of the leading-in part 224 is smaller than the maximum diameter of the circular bead 12 of the container 10, and because the circular bead 12 is circular, when the container mouth 11 is buckled into the clamping part 223, firstly the leading-in part 224 is propped open under the effect of the circular bead 12 of the container 10, then the circular bead 12 of the container 10 is clamped between the clamping part 223 and the cover bottom 21, and finally the leading-in part 224 retracts towards the central axis of the cover bottom 21, thereby achieving the purpose of gripping the paper lid with the container 10. If the cover bottom 21 is provided with the drinking hole 25, the drainage ring 23 has a flow guiding function, liquid is not easy to spill out, and if the drinking hole 25 is not provided, a space formed by the drainage ring 23 can be used for placing some drinking seasonings, such as sugar and the like used for drinking coffee.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
