Description

Technical Field

[0001] This utility model relates to the field of infusion bottle technology, specifically an integrated infusion plastic bottle. Background Technology

[0002] Infusion bottles are containers used in the medical field to hold intravenous fluids, and are mainly made of plastic materials such as PC, PP, and PE. PC has high transparency, high strength, high temperature resistance, and high impact resistance, and can withstand high temperature and high pressure sterilization processes, making it suitable for manufacturing the main body of infusion bottles; PP is lightweight and low cost, and is often used to manufacture components such as tubing, caps, and sealing rings for infusion bottles, making it safe and durable; PE is corrosion-resistant, and resistant to high and low temperatures, and is often used as a cushioning material and lining material for infusion bottles.

[0003] Limited by production technology and equipment, and in order to reduce material costs and minimize the use of expensive materials, many traditional infusion plastic bottles are manufactured by separately producing components of different materials for the bottle body and neck, which are then assembled. However, because the production process requires assembly, there is a certain probability of defective products due to weak assembly connections. Now, with the development of production technology and the upgrading of production equipment, it is possible to produce more economical integrated infusion plastic bottles. These bottles have the same material for both the body and neck, a secure connection, good sealing performance, and good impact resistance during storage and transportation. To meet market demand, an integrated infusion plastic bottle structure has been designed and proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated infusion plastic bottle, which aims to achieve a reliable connection and good sealing effect between the bottle body and the bottle mouth.

The bottom of the plastic bottle is provided with a clearance groove, the center of the clearance groove is provided with a storage groove, a three-fold hanging ring that is an integral part of the plastic bottle is provided in the storage groove, and a sealing label located below the three-fold hanging ring is affixed to the clearance groove. The three-fold hanging ring includes a connecting piece one, a connecting piece two, and a hanging ring connecting piece, which are Z-shaped folded and integrally structured. The connecting piece one is fixed to the plastic bottle body corresponding to the top of the inner wall of the storage slot. Folding grooves are provided between the connecting piece one and the plastic bottle body, between the connecting piece one and the connecting piece two, and between the connecting piece two and the hanging ring connecting piece.

[0006] Preferably, the bottle opening and the sealing partition are an integral structure.

[0007] Preferably, the top and bottom of the sealing plug are provided with easy-insertion grooves and snap-fit ​​protrusions located around the easy-insertion grooves.

[0008] Preferably, the bottom of the annular pressure plate is provided with a pressure ring that presses against the outer side of the top of the sealing plug and engages with the annular pressure plate, and the pressure ring and the annular pressure plate are an integral structure.

[0009] Preferably, the sealing partition has an easy-to-insert slot at the top center for engaging the bottom of the sealing plug with a snap-fit ​​protrusion.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This utility model features a bottle mouth made of the same material as the plastic bottle body and integrally welded by hot-melt welding. An integral sealing partition is installed inside the bottle mouth, making the plastic bottle body and bottle mouth an integrated structure. This improves the overall impact resistance and sealing effect of the infusion plastic bottle during the transportation and storage of infusion fluids, achieving a reliable connection and good sealing effect between the bottle body and bottle mouth of the integrated infusion plastic bottle.
