Problems solved by technology

The sealing rings under normal pressure in daily necessities are generally single-hole (hollow) sealing rings, such as the "seal ring and strip" disclosed in Chinese Patent No. 200720006558.6 is a hollow sealing ring, the hollow sealing ring is relatively soft and easy to deform , but the disadvantages of single-hole sealing rings are: first, low support capacity, poor contact sealing effect with the surface of objects; second, poor stability to temperature changes; third, poor mechanical strength and short service life

Embodiment Construction

[0013] The present invention relates to edible container sealing ring, such as figure 1 As shown, it includes a hollow strip 1, which is characterized in that the hollow 11 middle part of the strip 1 is provided with a connecting rib 12. Compared with the prior art, its outstanding positive effect is: one, the sealing ring is still It is hollow and maintains the characteristics of softness, and with the connecting ribs, it has strong support ability, large anti-extrusion force, and good sealing performance with the surface of the object; secondly, because there are connecting ribs in the hollow, the sealing ring is affected by temperature changes. The impact is small and the performance is stable; the third is that the mechanical strength such as tensile and compressive strength is high, and the service life is long, thus achieving unexpected effects and significant progress. Its described connecting rib 12 is one, and the cross-sectional shape of the corresponding strip is Ja...

Abstract

The invention relates to a sealing ring of a food vessel. The sealing ring comprises a hollow strip body and is characterized in that the hollow middle part of the strip body is provided with a connecting rib. Compared with the prior art, the hollow middle part of the strip body of the sealing ring is provided with the connecting rib; and the sealing ring has the following advantages that: (1) the sealing ring still has a hollow part and keeps the soft characteristic; and with the connecting rib, the sealing ring has strong supporting capacity, large anti-extrusion acting force, and good contact sealing performance with the surface of an object; (2) as the hollow part is provided with the connecting rib, the sealing ring suffers small influence of temperature change and has stable performance; and (3) the sealing ring has tensile resistance, pressure resistance, high mechanical strength and long service life. The sealing ring can be applied to a food vessel, food processing equipment, kitchen ware and various products which need to block gas and liquid leakage.

Description

technical field [0001] The invention relates to a sealing ring, which is mainly applicable to fresh-keeping boxes, space cups and the like. Background technique [0002] The sealing ring is mainly used to block the leakage of gas and liquid. The sealing rings used in industry mainly include rubber or metal sealing rings, which are usually made into solid sealing rings due to the high extrusion force after assembly. The sealing rings under normal pressure in daily necessities are generally single-hole (hollow) sealing rings, such as the "seal ring and strip" disclosed in Chinese Patent No. 200720006558.6 is a hollow sealing ring, the hollow sealing ring is relatively soft and easy to deform , but the disadvantages of single-hole sealing rings are: first, low support capacity, poor contact sealing effect with the surface of objects; second, poor stability to temperature changes; third, poor mechanical strength and short service life. Contents of the invention [0003] The ...
