Embodiment Construction
[0023] The present invention will be described in detail below with reference to the drawings and examples.
[0024] figure 2 It is a structural schematic diagram of the composite cover for riveting type easy-tear film sticking of the present invention. Such as figure 2 As shown, the composite cover for the riveting type easy-tear film of the present invention is composed of an outer cover 7 with a diaphragm 5 and a rubber gasket 4. The diaphragm 5 is connected to the middle part of the inner wall of the outer cover 7, and the outer cover 7 is divided into an upper half and a lower half.
[0025] The rubber gasket 4 is a circular gasket, and the outer peripheral edge part of the circular gasket extends upwards and downwards in the thickness direction respectively to form clamping parts 8, and the clamping parts 8 are connected in the riveting part 11 of the outer cover 7 described below. The middle part of the rubber gasket is evenly distributed with a plurality of punctu...

The invention discloses a riveting combined cover for film pasting of an easily-tearing film. The riveting combined cover is composed of an outer cover with a separation film and a rubber gasket, and the separation film is connected to the middle of the inner wall of the outer cover, so that the outer cover is divided into an upper half part and a lower half part; the upper half part of the outer cover is riveted to the outer portion of the rubber gasket, and the separation film is arranged below the rubber gasket. The riveting combined cover for film pasting of the easily-tearing film is formed by machining and assembling the outer cover with the separation film an the rubber gasket and heating and riveting the outer cover with the separation film and the rubber gasket, the injection forming process of an original inner cover is omitted, plastic raw materials are saved, and a large amount of electric energy consumed by the injection forming process is saved. Meanwhile, clean workshops for containing inner cover injection forming equipment and inner cover components are reduced, the construction cost of workshop facilities and power loads caused by daily purification and temperature control are effectively lowered, practicality is enhanced, and the production cost is reduced.
Description
technical field [0001] The invention belongs to the field of liquid medicine packaging, in particular to a combination cover for riveting easy-tear film sticking. Background technique [0002] Infusion products in plastic containers generally consist of two parts, the container and the liquid medicine. The container is mainly composed of a combination cover and a bottle body (or bag body), which has the functions of sealing and storing the liquid medicine, convenient use and transfer. The bottle body (or bag body) is the packaging material that directly contacts the liquid medicine. The inner surface of the combined cover is also in contact with the liquid medicine, so it also belongs to the packaging material in contact with the liquid medicine. [0003] Infusion products in plastic containers need to be used in clinical use through a closed puncture combination cover for drug addition, drug liquid extraction, and infusion operations. Therefore, rubber gaskets or similar ...
