Detailed Description
In order to make the technical solution of the present invention clearer, the present invention will be described in detail below with reference to fig. 1 to 5. It should be understood that the detailed description and specific examples, while indicating the scope of the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.
Example 1
The utility model relates to a sealing ring for a cup, which comprises an annular sealing ring main body 1 made of elastic materials, wherein at least one vent hole 2 is arranged on the annular sealing ring main body 1 along the radial direction, the section of the vent hole 2 is V-shaped, the V-shaped opening faces to the outer side, and the tip part of the vent hole is provided with a through hole 3 communicated with the inner side and the outer side of the annular sealing ring main body 1.
Preferably, the inner side wall of the annular sealing ring main body 1 is provided with an annular groove 4 with an inward opening, and the through hole 3 of the vent hole 2 is communicated with the annular groove 4. The number of the vent holes 2 is four, and the vent holes are uniformly distributed along the circumferential direction. The shape and size of the through hole 3 are preferably single round holes (with the diameter of 0.1-0.3 mm), or strip-shaped (with the length equal to the vent hole 2 and the width of 0.1-0.3 mm), or a plurality of parallel round holes (with the length equal to the vent hole 2, the diameter of 0.1-0.3mm and the distance of 0.1 mm). The sealing ring for the cup is integrally formed by elastic silica gel for food contact.
Example 2
The sealing ring for the cup with another structure comprises an annular sealing ring main body 1 made of elastic materials, wherein the annular sealing ring main body 1 is divided into an upper sealing ring 1-1 and a lower sealing ring 1-2, the upper sealing ring 1-1 and the lower sealing ring 1-2 are connected through a circular ring connecting piece with a V-shaped cross section, a V-shaped opening of the circular ring connecting piece faces towards the outside, and at least one through hole 3 is formed in a V-shaped tip of the circular ring connecting piece. The shape and size of the through holes 3 are preferably single round holes (diameter 0.1-0.3 mm), or long strips (length 0.5-5mm, width 0.1-0.3 mm), or a plurality of round holes side by side (length 0.5-5mm, diameter 0.1-0.3mm, spacing 0.1 mm).
Preferably, the upper sealing ring 1-1, the lower sealing ring 1-2 and the ring connecting piece are of an integral structure and are made of elastic silica gel for food contact. The number of the through holes 3 is four, and the through holes are uniformly distributed along the circumferential direction.
It can be seen that the sealing rings for cups of the two structures have the technical characteristics that the through holes 3 have the same shape and size and have V-shaped sections.
When the cup is used, the cup cover is screwed down to press the sealing ring for the cup, the vent hole 2 on the annular sealing ring main body 1 is closed, the cross section of the vent hole is of a V-shaped structure, the structure is equivalent to a check valve, the pressure in the cup acts on the outer side surface of the V shape, the through hole 3 is closed more tightly, and the water in the cup can be prevented from overflowing; when opening the bowl cover, the sealing washer extends naturally for the cup, and the balanced atmospheric pressure in the through-hole 3 entering cup of air vent 2 is followed to the outside air, and the bowl cover can be opened smoothly, and the cross-section is the structure of V-arrangement, has the guide effect, because the pressure effect of negative pressure in the cup, outside air current can make air vent 2 and through-hole 3 enlarge on the V-arrangement inside wall, and the air current passes through with higher speed, makes the inside and outside atmospheric pressure of cup obtain the balance more fast. The silica gel material can expand in a hot environment, so that the air holes are further closed more tightly.
