GB/T 17449—1998
This standard specifies the size series of threaded glass bottle mouths. The size of the anti-theft threaded glass bottle mouths is not equivalent to ISO9056:1990 "Glass Containers-Anti-theft Bottle Mouth Series-Dimensions", the single-threaded glass bottle mouth refers to the British standard BS1918Part1-1978 "Glass Container Bottle Mouth Part 1 Continuous Thread Bottle Mouth Specifications", and the multi-threaded glass bottle mouth is combined with the actual domestic situation. This standard is proposed by China Packaging Corporation. This standard is under the jurisdiction of the Glass Container Sub-Technical Committee of the National Packaging Standardization Technical Committee. The responsible drafting unit of this standard: Beijing Glass Product Quality Supervision and Inspection Station. The participating drafting units of this standard: Shanxi Xinghua Village Fen Liquor Factory Co., Ltd., Beijing Glass Group Corporation, Beijing Glass Factory No. 6, Fujian Putian Jinshi Glass Products Co., Ltd.

Packaging-Glass containers----Thread finish dimensions
This standard specifies the definition, classification and dimensions of threaded glass bottles. This standard applies to threaded glass bottles containing non-inflated materials. 2 Definitions
This standard adopts the following definitions.
2.1 Pilferproof thread finish of glass A threaded glass bottle that needs to twist off the bottle cap before opening. Multiple-start thread finish of glass 2.2
Connection: A threaded glass bottle with discontinuous threads between the threads. 2.3 One-start thread finish of glass A threaded glass bottle with continuous threads between the threads. 2.4 Shape
The shape and structure of the threaded glass bottle.
3 Classification
Divided into three series according to the use requirements.
3.1 Anti-theft threaded glass bottle mouth series
GB/T17449- 1998
neq ISO 9056:1990wwW.bzxz.Net
According to the use, it is divided into three categories: A, B, and C, namely standard, deep mouth, and super deep mouth. Each category is divided into 1 to 3 forms, see Figure 1, Figure 2, and Figure 3 for details. There are two ways to recess the super deep bottle mouth with a nominal diameter of 30mm. 3.2 Multi-threaded glass bottle mouth series, see Figure 4 for details. 3.3 Single-threaded glass bottle mouth series, see Figure 5 for details. 4 Size
4.1 The size of the anti-theft threaded glass bottle mouth shall comply with the provisions of Table 1. 4.2 The size of the multi-threaded and single-threaded glass bottle mouth shall comply with the provisions of Table 2. Note: The size should be selected according to the shape of the bottle mouth, as shown in Figures 1 to 5 and the attached table. All dimensions without tolerance are nominal dimensions, and the bottle mouth thickness should meet normal operation requirements.
4.3 The calculation of the helix rise (roller lead angle) is shown in formula (1). tga
Wherein: β-helix rise angle (roller lead angle), °; pitch, mm;
dj—thread outer diameter, mm;
dbottle mouth outer diameter, mm.
