Description
Technical field
The utility model relates to a kind of bottle cap, particularly relates to a kind of bottle cap with sealing inner plug.
Background technology
The interior plug sealing of existing bottle adopts glass bottle and interior plug end face close contact formation sealed environment to realize, its sealing property can cause different sealing effectivenesss according to plug structure difference in it, have the hidden danger of seal failure, according to the feedback of user to sealing problem, technical personnel is internally filled in and has been carried out improving (background technology one) with the hermetically-sealed construction of glass bottle, the interior plug adopting circular plastic uptake pad 1 to be assemblied in upper cover 2 as shown in Figure 1 intercepts on buckle 3 and locates, interior plug intercepts buckle 3 and can prevent circular plastic uptake pad 1 from use dropping, upper cover 2 and the lower pipe 4 mode overall package of ultrasonic welding, to be that the end face axial of bottle is stressed contact with plastic uptake pad sealing principle after wine covers bottle, cause the crimp of plastic uptake pad to form closed environment thus ensure sealing, its antifalsification relies on the irrecoverability of the fracture of weld nugget to realize.
In actual production process, there is the defects such as sealing property, assembly performance and detection perform due to such scheme, this structure carries out again improving (background technology two) by technical personnel, as shown in Figure 2, the mode that original upper cover and the assembling mode of lower pipe change screw thread snapping into by the mode of ultrasonic welding is connected, interior plug 5 uses LDPE (Low Density Polyethylene) moulding, the top internal diameter interference fit (flush fit) of depression outer-diameter end face and glass bottle is adopted to realize sealing, lower pipe 6 increases screw thread and coordinates with upper cover 7, and increases unlatching tooth for false proof.
In actual use, the interior plug sealing that the mode of ultrasonic welding is assembled there will be the hidden danger connecting shakiness, and detection can not be carried out to it to judge, for follow-up process of doing over again brings inconvenience, further, interior plug is circular plastic uptake pad, and material may not meet the material of food security containing plasticiser etc., and its reliability sealed can not be ensured, can the hidden danger such as seepage be occurred.
The mode of screw thread snapping connects, upper cover increases opening groove and coordinates with unlatching tooth, lower pipe increases unlatching tooth position and ensures its antifalsification, false proof characteristic is realized by the irrecoverability of the fracture of opening tooth, interior plug structure and material also change, material changes LDPE (Low Density Polyethylene) moulding into, meet food packaging requirement, structure changes to depressed, sealing is realized by the outer-diameter end face of pit bit and the interference fit of internal diameter of the bottleneck end face, its leak tightness increases substantially, and can detect it, unstable and non-detectable trouble is connected although there will not be, but, because interference fit after upper bottle is opened, wherein, plug may come off with upper cover and be deposited in glass bottle, bottle cap is caused effectively not open, give in life to use and bring great inconvenience.
