Problems solved by technology

The glass feeding bottles of the above-mentioned patents are all equipped with a structure to prevent breaking, but structurally speaking, the bottles of the above-mentioned patents are all single-layer structures, and the thermal insulation performance is relatively poor. protection effect, but because there is no good bonding of glass fragments, it is still harmful and does not achieve the purpose of safety; and in the prior art, there are also people who have designed a double-layer glass bottle, and a vacuum structure is taken between the two layers of glass. Although it can Improve the heat preservation effect, but there is a risk of being fragile. Once broken, it is easy to hurt infants and young children, and cannot guarantee the safety of infants and young children

Embodiment 1

[0038] Example one, such as Figure 1 ~ Figure 6 Shown:

[0039] The first embodiment discloses a manufacturing process of a double-layer bottle cup. The manufacturing process specifically includes the following steps:

[0040] Step 1: Make a single-layer outer preform 1 which can be made of plastic or glass material. The outer preform 1 has an open mouth.

[0041] Step 2. Make a concave mold 3 with the same size as the outer preform 1 in step 1. The concave mold 3 can be made by casting silicone rubber as a fixed mold for the outer preform 1; the concave mold 3 is specifically made The process is as follows:

[0042] (1) Brush the release agent on the outer surface of the outer preform 1, while fixing the outer preform 1 and placing it in the middle of the mold;

[0043] (2) After mixing the silicone rubber with a chain extender and a vulcanizing agent in a ratio of 1:1, vacuum degassing is carried out. Among them, the chain extender is preferably methyl vinyl bispyrrolidone silane, ...

Embodiment 2

[0061] Example two, such as Figure 7 , Figure 8 Shown:

[0062] The manufacturing process of the double-layer preform of the second embodiment and the first embodiment is exactly the same, the difference is that the outer preform 1'used in the second embodiment is a double-ended baby bottle with a bottle opening at the upper and lower ends. The small hole 11' of the outer preform 1'is opened on the outer surface of one side of the bottle mouth, see Figure 7 Since the outer preform 1'is directly used as a model, the blowing of the inner preform 2'does not require additional molds, and a more complex bottle shape can be made, which is compared with the common ones in the prior art The straight cylindrical bottle cup, the manufacturing process adopted in this embodiment can enrich the model and appearance of the product, meet the use needs of users with different functions, and have a broader practical prospect.

Abstract

A process for making a double-layer bottle/cup is characterized by including the first step of making a single-layer outer bottle blank, the second step of making a concave mold the same as the outer bottle blank in size, the third step of drilling a small hole in the bottom of the outer bottle blank, the fourth step of blowing air into a bottle opening of the outer bottle blank to form an inner bottle blank with the outer bottle blank as a model and the fifth step of injecting elastic soft silicone rubber to fill the gap between the inner bottle blank and the outer bottle blank from the small hole formed in the bottom of the outer bottle blank to obtain the bottle/cup of a double-layer structure. Compared with the prior art, the process has the advantages that the outer bottle blank serves as the model, the inner bottle blank is directly formed in the outer bottle blank through blowing, another mold does not need to be made, and the whole process is simple and practicable; the outer bottle blank and the inner bottle blank are fixedly connected into a whole through the elastic soft silicone rubber, so the feeding bottle or the cup can be effectively prevented from falling off and being broken into pieces accidentally, and use security is effectively improved.

Description

Technical field [0001] The invention relates to a manufacturing process of a bottle body, in particular to a manufacturing process of a bottle cup with a double-layer structure. Background technique [0002] Most of the bottles / cup bodies used to hold liquids in daily life are single-layer structures made of glass or plastic materials. In particular, baby bottles require stricter manufacturing requirements because of their special use. . [0003] Although the baby bottle of the plastic bottle gallbladder is not afraid of falling, long-term use of plastic will have certain toxins, and it is easy to breed bacteria because the inner wall of the plastic is difficult to clean after use. The plastic material is also prone to scratches during cleaning, which affects the aesthetics of use. Therefore, many baby bottles currently use glass liners. The glass is non-toxic, easy to clean and not easy to produce bacteria. However, the disadvantages of glass liners are that they are heavy and di...
