Soft and hard silica gel nipple and manufacturing method thereof

Abstract

The invention discloses a soft and hard silica gel nipple, which comprises an inner layer and an outer layer, wherein the inner layer is made from high-hardness silica gel; the inner layer is 0.79-0.81mm thick and is 48-52 degrees in shore hardness; the outer layer and the inner layer, when produced, are integrally connected; the outer layer is made from low-hardness silica gel; and the outer layer is 0.89-0.91mm thick and is 8-12 degrees in shore hardness. With the adoption of a specific liquid-state silica gel injector, two liquid-state silica gels, which are different in hardness, are injected into A set of liquid-state silica gel mold and B set of liquid-state silica gel mold in a separated mode by conducting an injection-molding process twice, and then high-temperature vulcanization is conducted, so that the nipple is shaped. Related nipple standard requirements can be satisfied, and the demands of the nipple in taste, softness and comfort can be met, so that effects of a mother'snipple can be completely achieved. The finished nipple provided by the invention has the advantages of being simple in structure, reasonable in design, high in production efficiency, good in serviceeffect, easy for promotion and application and the like.

Description

technical field [0001] The invention relates to the technical field of pacifiers, in particular to a soft-hard silicone pacifier and a manufacturing method thereof. Background technique [0002] The pacifier is installed on the body of the feeding bottle and is used to replace the mother's nipple for infants to suck and eat. In order to ensure the safety performance of pacifiers, the state, localities, industries, enterprises, etc. have formulated and promulgated a series of corresponding standards, which involve mandatory terms such as "acupuncture and pull resistance performance" and "safety holding force". [0003] At present, the manufacturing process of the pacifiers produced by various manufacturers is to inject single-hardness liquid silicone into the mold once, and then form them after high-temperature vulcanization. The existing pacifiers on the market are all produced by this process. In order to ensure the safety of the pacifier In line with the requirements of t...

Problems solved by technology

[0003] At present, the manufacturing process of the pacifiers produced by various manufacturers is to inject single-hardness liquid silicone into the mold once, and then form them after high-temperature vulcanization. The existing pacifiers on the market are all produced by this process. In order to ensure the safety of the pacifier In line with the requirements of the above standards, all manufacturers use relatively high hardness liquid silicone to produce pacifiers. Although this can make the pacifier meet the standard requirements, it cannot achieve the effect of mother's nipples in terms of taste, softness, and comfort. Our company Another kind of dual-hardness silicone pacifier produced, although it is also a pacifier formed by two kinds of silicone with different hardness, its structure is composed of soft and hard silicone at the front end of the pacifier and high-hardness silicone at the back end. This structure is to a certain extent It meets the safety, taste, softness and comfort requirements of the pacifier, but it cannot fully achieve the effect of the mother's nipple.
