A plastic packaging bottle with a pet screw cap

Abstract

The invention provides a plastic packing bottle with a PET threaded buckling cover. As the buckling cover is made of a PET material, the buckling cover is high in hardness, high in transparency, safe and durable, can be firmly buckled with a flange, and is difficult to fall off and deform. The plastic packing bottle comprises a bottle body and the buckling cover, wherein a supporting ring is pressed on the circumferential wall of an opening of the bottle body; an annular supporting bench protruding into the opening of the bottle body is arranged on the inner face of the supporting ring and is connected with a metal seal cover through a circular easy-pull trace; internal threads are formed on the inner circumferential face of the buckling cover; the middle part of the outer face of the supporting ring protrudes out of the opening of the bottle body to form a flange, so that a structure capable of clamping the internal threads is formed; the buckling cover is made of the PET material; external threads matched with the internal threads are formed at a position, at the lower end of the supporting ring, on the bottle body; the upper end face of the metal seal cover is connected with a pull ring through a rivet; the part, positioned at the front end of the rivet, of the pull ring is arranged on the circular easy-pull trace and serves as a tip end; an avoiding slot is formed in the metal seal cover at the position, at the lower end of the rear part of the rivet, of the pull ring; backwards extending reinforcement ribs are arranged at positions, on both sides of the pull ring, of the metal seal cover.

Description

technical field [0001] The invention relates to a packaging bottle, in particular to a plastic packaging bottle with a PET screw cap. Background technique [0002] Existing plastic packaging bottles are pressed on the opening of the bottle body with a metal cover and a flange for snapping the buckle cap. The buckle cap fits on the opening of the bottle body and is locked by the flange. The bottle body can be unsealed by tearing off the metal cover. The existing buckle caps are made of PP and PE materials, which are soft in texture, low in hardness, and easy to deform. It is easy to fall off under contact, and the button cap made of PP and PE materials has low transparency, and the food inside the bottle cannot be seen through the button cap well, and the appearance is not beautiful. When in use, there is no gland metal cover on the mouth of the bottle body, so that the food preservation effect is not good before unsealing. Contents of the invention [0003] In view of th...
