Detailed Description
The present invention will be further described with reference to the accompanying drawings. The utility model provides a high leakproofness bottle lid of integral type which characterized in that: it includes the main lid 1 that forms by the stereoplasm plastic is moulded plastics, and the inner cup top injection moulding of main lid 1 has sealing washer 2, and sealing washer 2 is fixed as an organic whole with main lid 1 hot melt, and sealing washer 2 width is greater than the setting of bottleneck width.
The main cover body 1 is formed by injection molding of PP plastic.
The main cover body 1 is made of PE plastic through injection molding.
The sealing ring 2 is made of TPE plastic through injection molding.
The thickness of the sealing ring 2 is 1.5mm-4mm.
The width of the sealing ring 2 is 3mm-8mm.
As shown in fig. 3, the outer cylindrical surface of the main cover 1 is further provided with a label 3.
As shown in fig. 4, the label 3 is formed on the outer cylindrical surface of the main cover 1 and penetrates the main cover 1.
When the product is produced: which comprises the following steps:
a: the main cover body 1 and the sealing ring 2 adopt a double-color injection molding process, raw materials for producing the sealing ring 2 are added into the charging barrel with the A nozzle, and raw materials for producing the main cover body 1 are added into the charging barrel with the B nozzle.
B: the injection molding machine heats the raw material of the sealing ring 2 to a molten state, and the molten liquid flow is injected into a cavity of an injection mold from a nozzle A of a charging barrel of the injection molding machine to mold the sealing ring 2;
c: after the first-shot sealing ring 2 is formed, a movable template of a double-color injection molding machine is rotated by 180 degrees to be matched, the injection molding machine heats the raw material of the main cover body 1 to molten liquid flow, and the molten liquid flow is injected into a cavity of a second-shot mold from a nozzle B of a charging barrel of the injection molding machine to form the main cover body 1, so that the main cover body 1 and the sealing ring 2 are fused into a whole;
wherein, the material of pairing of double-colored moulding plastics must satisfy two basic compatible conditions, and it is compatible with the course of working promptly to adhere, can both fine two basic compatible conditions of satisfying through experimental PP material or PE material and TPE material, can make the sealing washer shaping back, during the secondary main lid of moulding plastics, enables main lid and sealing washer adhesion as an organic whole, can effectively avoid both occurrences of separation in later stage.
D: periodically opening the die: after the mold is opened periodically, the two-shot product is ejected out, and the movable mold plate of the molding machine of the double-color injection molding machine is rotated by 180 degrees to reset.
And in the step B, a nozzle of a charging barrel A of the injection molding machine is injected into a cavity of the one-shot mold to form the marking paste 3, and during the two-shot molding, the injection molding machine heats the raw material of the main cover body 1 to molten liquid flow and injects the molten liquid flow into the cavity of the two-shot mold from the nozzle of the charging barrel B of the injection molding machine to form the main cover body, so that the marking paste 3 and the outline of the main cover body 1 are fused into a whole. Wherein, can mark the plastics colour of subsides with the shaping and carry out the differentiation setting with the colour of main lid to there is bright contrast with main lid, so that the user can be more clear observe mark the subsides content, promote user identification ability.
Compared with the prior art, the structure in this case is with main lid and sealing washer integrated into one piece, consequently, when this bottle lid passes through screw-thread fit with the plastic bottle and screws up, the TPE flexible glue part is hugged closely as sealing washer and bottleneck terminal surface and is compressed tightly, has high leakproofness. Therefore, the packaging bottle using the main cover body does not need to be sealed by arranging accessories such as an aluminum foil sealing sheet, a hot melt adhesive film, an aluminum cover, a gasket and the like, sealing can be completed only by screwing the cover body, the production cost can be greatly reduced, the production efficiency is improved, and the main cover body can be widely popularized and used.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
