After the airbag is inflated, the shape of the airbag is compared with the inner wall of the cylinder. Adaptation, there is a transparent window on the side of the cylinder. When the cylinder is inelastic, the resilient reset ring is added to the cylinder to increase its elasticity. This ointment packaging cylinder can be squeezed after use by the elastic force of the cylinder. The negative pressure is generated in the cylinder body, and the outside air enters the airbag through the one-way air inlet valve, so that the depression on the cylinder body is added in time, so that the ointment is The loading tube is always in a full state, and the ointment can ensure that it is used up without wasting through the action of the airbag.
