Flint Glass Round Jars with Screw Neck

Description

The Flint Glass Round Jars with Screw Neck, also known as clear glass cosmetic jars, wide-mouth glass containers or screw-neck sample jars, are designed for storing and presenting creams, balms, powders, spices and other compatible materials. Manufactured from clear flint glass, these containers provide good visibility of their contents. Their transparent construction makes them suitable for applications where product appearance and visual inspection are important. The range includes four capacities: 30 mL, 65 mL, 120 mL and 125 mL, allowing customers to select a container according to the required volume, packaging format and storage conditions.

Each jar features a continuous-thread screw neck, designed to accept a compatible screw cap with the matching neck finish. The 30 mL glass jar has a 38-400 neck finish and compact dimensions of 46.2 mm high × 40.5 mm diameter. Its small capacity makes it suitable for cosmetic samples, trial formulations and limited quantities of compatible materials. The 65 mL glass jar features a 48-400 screw neck, measures 52.5 mm high × 53.1 mm diameter and provides a wider container for creams, balms, spice blends and product samples. The 120 mL round glass jar has a 58-400 screw neck and measures 64.6 mm high × 61.2 mm diameter. Its relatively wide opening allows convenient access when filling or removing thicker products.

The 125 mL glass jar features a 48-400 screw neck and measures 84 mm high × 53.8 mm diameter. Its taller profile provides an alternative for products requiring a narrower external container diameter. All four variations feature round glass bodies, making them suitable for compatible labels used for product identification, batch details and contents information. The jars can be used in cosmetic formulation laboratories for holding creams, body scrubs, ointment bases and small-batch trial formulations, provided the contents are compatible with the glass and selected closure. They are also suitable for dry ingredients and sample packaging, including spices, powders and compatible solid materials. Suitability for food-contact applications should be confirmed against the intended use and applicable requirements.

The 400-series neck finish identifies a continuous-thread closure configuration. Matching the thread diameter and finish series is important when selecting suitable screw caps. For example, the 30 mL jar requires a 38-400 compatible closure, while the 65 mL and 125 mL jars require 48-400 closures. The 120 mL variation requires a 58-400 closure. An airtight or leak-resistant seal depends on the selected cap, liner, application torque and compatibility with the contents. The glass jar alone does not guarantee sealing performance. Individual jar weights range from 46 g to 130.5 g, providing useful information when assessing packaging weight and handling requirements.

The glass construction allows the jars to be reused where suitable cleaning and inspection procedures are established. However, thermal resistance, autoclaving suitability and chemical compatibility have not been specified for these particular containers. Safety Precautions: Inspect jars for chips, cracks or other damage before filling. Avoid sudden temperature changes and excessive impact. Do not use for pressurised storage or heating unless the manufacturer confirms suitability. Verify container and closure compatibility with the intended contents. Each variation is supplied in its specified carton quantity. Screw caps, sealing liners and other accessories are not confirmed as included.
