Products Description
Compact Portion Size for Everyday Carry
The 370 ml format is suited to fruit portions, snacks, sauces, side dishes, desserts, and light meals. This gives retailers a clear product position for student lunch kits, office meal accessories, children's food storage, and compact meal-preparation collections.
Glass Visibility with a Practical Plastic Lid
The transparent glass body allows users to identify the contents directly, while the lightweight plastic lid provides a separate handling component for daily opening and closing. This combination offers buyers a balanced material story between food visibility, container structure, and portable use.
Secure Four-Side Closure for Transport
The lid uses side clips to hold the cover in place, supported by a silicone sealing ring around the edge. This closure design helps create a more contained interior during transport and storage; final leakage performance should be confirmed according to the selected lid and seal configuration.
Microwave-Ready Borosilicate Glass Positioning
The product visual identifies the glass as high borosilicate and indicates heat resistance up to 120°C for microwave use. Buyers can position the container for reheating prepared food, provided the lid is handled according to the final product instructions and the confirmed production specification.

Product Details
Layered Sealing Interface Around the Glass Rim
The container uses a plastic lid that overlaps the upper edge of the glass body, with a silicone ring positioned around the contact area. When the side clips are closed, the lid is held against the rim to create a more controlled seal line. This structure gives buyers a clear explanation of how the glass container and lid work together during storage and transport.
Small Footprint with Portion-Focused Capacity
The 145 × 105 mm reference footprint is designed around a compact serving size rather than a large family meal. Its rectangular outline can sit neatly on refrigerator shelves and inside lunch bags, while the 47 mm reference height keeps the container relatively shallow for fruits, snacks, salads, and side dishes that need quick visibility.
