Abstract
The utility model discloses an inner pad of a bottle cap. An effective sealing face of the inner pad is composed of an inner ring, an outer ring and a top plane, wherein a slope face of the inner ring is in interference fit with the inner diameter of a bottle opening, a protrusion is formed along the outer edge of the periphery of the inner ring, the outer portion of the protrusion slants to the outer ring to form the slope face of the inner ring, and the thickness of the inner pad of the bottle cap is 1-2mm. The inner pad of the bottle cap has three effective sealing faces, the slope face of the inner ring is in interference fit with the inner diameter of the bottle opening to combine advantages of an inner plug of the bottle cap and the plane, effects of increasing pressure and corresponding sealing force are achieved, the pad and the bottle cap adopt once molding and pasting processes, corresponding locations of the pad and the bottle cap are guaranteed to be accurate, the pad cannot drop from the inside of the bottle cap, opening force is good while good sealing performance is guaranteed, good sealing performance of a rubber plug is avoided, the problem of big opening force is solved, and requirements for the healthy bottle cap, good sealing performance and small opening force are met.
Description
Technical field
The utility model belongs to the packing technique field, relates in particular to a kind of bottle cap.
Background technology
The original bottle cap in market is divided into plug. two kinds of flat pad
Plug; Complex-shaped, the first injection-compression molding of palpus, then put into inside lid, production efficiency is low, no matter machinery enters pad or staff enters pad, easily causes secondary pollution, can't guarantee the hygienic requirements of bottle cap, and plug is for guaranteeing sealing effectiveness, and elasticity is too large usually, causes when uncapping and opens greatly difficult because of friction force.
Flat pad; Being divided into bonding and later stage of mold pressing enters two kinds of techniques of pad, because sealing surface is single, when running into packing gassiness drink and needing the drink of high-temperature sterilization, causes interior pad and bottleneck top contact surface to reduce because interior pressure increases, and easily reduces sealing property, causes leakage.
The utility model content
The utility model provides a kind of bottle cap, though for solving the good still crack force of prior art plug sealing property greatly and the low shortcoming of flat pad sealing property.
For solving the problems of the technologies described above, the bottle cap that the utility model embodiment provides, adopt following technical scheme:
A kind of bottle cap, its effective sealing face are that inner ring, outer ring and plane, top form, and wherein, described inner ring inclined-plane and internal diameter of the bottleneck are interference fit.
Further, described inner ring periphery forms projection along the edge.
Further, the outside of described projection is formed slopely the inner ring inclined-plane to the outer ring.
Particularly, the thickness of described bottle cap is the 1-2 millimeter.
a kind of bottle cap that the utility model provides, the effective sealing face is three, and inner ring inclined-plane and internal diameter of the bottleneck are interference fit, advantage two-in-one with plug and plane in bottle cap, reaching pressure increases, sealing force is the effect of corresponding increase also, pad and bottle cap adopt one-shot forming and bonding technique, the opposite position of guaranteeing pad and bottle cap is accurate, and pad can not come off in bottle cap, when guaranteeing that leak tightness is good, crack force is exhibits excellent also, avoided the plug good seal performance, and the large shortcoming of crack force, reach the bottle cap health. good seal performance. the requirement that crack force is little.
Description of drawings
Fig. 1 is the structural representation of bottle cap described in the utility model.
Reference numeral: 1-inner ring 2-outer ring 3-pushes up 1-1-projection 1-2-inner ring inclined-plane, plane
The specific embodiment
a kind of bottle cap that the utility model provides, the effective sealing face is three, and inner ring inclined-plane and internal diameter of the bottleneck are interference fit, advantage two-in-one with plug and plane in bottle cap, reaching pressure increases, sealing force is the effect of corresponding increase also, pad and bottle cap adopt one-shot forming and bonding technique, the opposite position of guaranteeing pad and bottle cap is accurate, and pad can not come off in bottle cap, when guaranteeing that leak tightness is good, crack force is exhibits excellent also, avoided the plug good seal performance, and the large shortcoming of crack force, reach the bottle cap health. good seal performance. the requirement that crack force is little.
Below in conjunction with accompanying drawing, the bottle cap that the utility model embodiment offers is described in detail.
As shown in Figure 1, a kind of bottle cap that the utility model embodiment provides, its effective sealing face are that inner ring 1, outer ring 2 and plane, top 3 form, and wherein, described inner ring inclined-plane and internal diameter of the bottleneck are interference fit.
Described inner ring 1 periphery forms projection 1-1 along the edge.
The outside of described projection 1-1 2 is formed slopely inner ring inclined-plane 1-2 to the outer ring.
The thickness of described bottle cap is the 1-2 millimeter.
Bottle cap effective sealing face is three, and inner ring inclined-plane and internal diameter of the bottleneck are interference fit, advantage two-in-one with plug and plane in bottle cap, when innermost circle runs into pressure when high-temperature sterilization (after carbonated beverage or can), it is withstand voltage to bottleneck that pressure promotes inner ring, reaches pressure and increase, sealing force is the effect of corresponding increase also, pad and bottle cap adopt one-shot forming and bonding technique, guarantee that the opposite position of pad and bottle cap is accurate, and pad can not come off in bottle cap.
Structural advantage;
adopt high-temperature injection. the mold pressing one-shot forming. adhesion technique, clean hygiene, production efficiency is high, select the PVC.TPE.EVA environment-friendly materials, meet the drink of need high-temperature sterilization or the seal request of gassiness drink, this gasket construction can effectively replace plug. flat pad, every pad possesses the advantage of plug and flat pad simultaneously, because sealing surface is three three-dimensional seal, strengthened the sealing property of bottle cap, and the surface is fine and smooth, friction force is little, when guaranteeing that leak tightness is good, crack force is exhibits excellent also, avoided the plug good seal performance, and the large shortcoming of crack force, reach the bottle cap health. good seal performance. the requirement that crack force is little.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion by described protection domain with claim.
Claims (4)
1. bottle cap, its effective sealing face are that inner ring, outer ring and plane, top form, and it is characterized in that, described inner ring inclined-plane and internal diameter of the bottleneck are interference fit.
