Description
Technical Field
The utility model belongs to sealed field, more specifically say so and relate to a medicine bottle headspace accuse oxygen sealing ring and seal structure.
Background
In pharmaceutical liquid products, there are often products that need to meet headspace oxygen requirements.
Previous bottle neck seals have often been sealed in one pass. Once the seal is damaged in the production process, the oxygen content in the headspace of the product exceeds the standard, waste products are generated, the product yield is influenced, and the benefit is reduced.
Disclosure of Invention
An object of the utility model is to provide a medicine bottle headspace oxygen control sealing ring and seal structure can solve the method that headspace oxygen content exceeds standard.
According to the utility model provides a technical scheme: the utility model provides a medicine bottle headspace accuse oxygen sealing ring, the sealing ring is cyclic annular, medicine bottle headspace accuse oxygen sealing ring inner ring middle part sets up the pressure cock head installation department, medicine bottle headspace accuse oxygen sealing ring inner ring lower part sets up first sealing ring, first sealing ring top sets up the second sealing ring, first sealing ring with it has the elasticity clearance to open between the second sealing ring.
Further, the sealing ring is made of ethylene propylene diene monomer.
A sealing structure for controlling oxygen in headspace of a medicine bottle comprises a medicine bottle headspace oxygen control sealing ring, wherein the medicine bottle headspace oxygen control sealing ring is arranged on the periphery of a cork pressing head; one side of the pressure plug head is provided with a vacuum pumping pipe, and the other side of the pressure plug head is provided with a nitrogen charging pipe; the medicine bottle is placed to pressure cock head below, first sealing ring with the second sealing ring is located medicine bottle bottleneck periphery.
Furthermore, the included angle b between the first sealing ring and the second sealing ring is smaller than the included angle a of the bottle neck of the medicine bottle.
Compared with the prior art, the utility model, have following advantage:
1. the utility model discloses simple structure forms twice with the medicine bottle and seals, ensures the cavity leakproofness of evacuation and nitrogenization.
2. The utility model uses the ethylene propylene diene monomer, meets the use requirement of the medicine grade rubber, and can carry out online sterilization.
Drawings
Fig. 1 is a structural diagram of the medicine bottle headspace oxygen control sealing ring of the utility model.
Fig. 2 is a schematic diagram of the sealing structure of the present invention.
Fig. 3 is a schematic structural view of the medicine bottle of the present invention.
In the figures 1-3, the device comprises a medicine bottle 1, a press plug 2, a vacuum tube 3, a nitrogen filling tube 4, a medicine bottle headspace oxygen control sealing ring 5, a press plug mounting part 5-1, a first sealing ring 5-2, a second sealing ring 5-3 and the like.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 2, the utility model relates to a seal structure of medicine bottle headspace accuse oxygen, including medicine bottle 1, the cover is established and is pressed the cock head 2 on the 1 bottleneck of medicine bottle, presses cock head 2 one side to set up evacuation tube 3, and the opposite side sets up fills nitrogen gas pipe 4, and medicine bottle 1 and cork head seal up through medicine bottle headspace accuse oxygen sealing ring 5.
As shown in fig. 1, the medicine bottle headspace oxygen control sealing ring 5 is ring-shaped, the middle of the inner ring of the medicine bottle headspace oxygen control sealing ring 5 is provided with a cork pressing head installation part 5-1, the size of the cork pressing head installation part 5-1 is slightly smaller than the outer diameter of a cork pressing head 2, the periphery of the cork pressing head 2 can be firmly held by the cork pressing head installation part 5-1, the lower part of the inner ring of the medicine bottle headspace oxygen control sealing ring 5 is provided with a first sealing ring 5-2, a second sealing ring 5-3 is arranged above the first sealing ring 5-2, and the first sealing ring 5-2 and the second sealing ring 5-3 are both used for sealing the bottleneck of the medicine bottle 1.
The included angle b between the first sealing ring 5-2 and the second sealing ring 5-3 is smaller than the included angle a of the bottleneck of the medicine bottle 1, so that the bottleneck of the medicine bottle 1 has radial pretightening force on the medicine bottle headspace oxygen control sealing ring 5, and the sealing effect is better.
An elastic gap 5-4 is arranged between the first sealing ring 5-2 and the second sealing ring 5-3, so that the first sealing ring 5-2 has small resistance when contracting.
The working process of the utility model is as follows:
as shown in fig. 2, the medicine bottle headspace oxygen control sealing ring 5 is mounted on the corking head 2 of the filling and sealing machine. When a medicine bottle 1 filled with liquid enters a lifting tray of a corking station, the medicine bottle 1 rises to enter a bottleneck sealing ring 5, the bottleneck of the medicine bottle 1 and the bottleneck sealing ring 5 form sealing at a first sealing ring 5-2 and a second sealing ring 5-3, a filling machine vacuumizes the medicine bottle 1 through a vacuumizing tube 3 of a corking head 2, nitrogen is filled into the medicine bottle 1 through a nitrogen filling tube 4, and after certain times, the corking head presses a rubber plug on the bottleneck to complete the encapsulation of the product.
