Production process of a functional bottle cap gasket

Abstract

Disclosed is a production technology of a functional bottle cap gasket. The production technology of the functional bottle cap gasket comprises the steps of the prefabrication working procedure and the combination working procedure. In the prefabrication working procedure, a first base material layer, a second base material layer, an outer membrane layer and an information layer are made, the information layer is arranged on the upper end face of the second base material layer or the outer membrane layer, and identification patterns or characters or anti-counterfeiting information or any combinations of the identification patterns, the characters and the anti-counterfeiting information are arranged on the information layer. The combination working procedure comprises the following steps that step 1, the outer membrane layer and the upper end face of the second base material layer are combined through the combination technology; and step 2, the lower end face of the second base material layer and the end face of the first base material layer are combined through the combination technology, so that a combined gasket body is formed. According to the production technology of the functional bottle cap gasket, due to the fact that an exiting thick base material layer is divided into two or more layers, the thickness of the second base material layer which is combined with the outer membrane layer is smaller than the total thickness of the base material layers, the difference of tension and deformation in the winding process is reduced, the outer membrane layer and the base material layers are not prone to misalignment and corrugation, and the yield is high.

Description

technical field [0001] The invention relates to a production process of a bottle cap gasket provided with pictures, texts or anti-counterfeiting information. Background technique [0002] Graphical information is printed on bottle caps of bottled beverages and wines to achieve labeling or anti-counterfeiting effects. If the graphic information is directly printed in the bottle caps, it is very easy to pollute the beverages or wines in the bottle. [0003] At present, the bottle caps of bottled beverages and wines are usually equipped with a gasket to enhance the sealing effect. Such bottle gaskets usually do not have any information attached, although it is conceivable to print the above-mentioned graphics or anti-counterfeiting information on the bottle gasket. However, it is still difficult to avoid the problem of contamination of beverages or liquor in the bottle. [0004] For this reason, the applicant has developed a bottle pad specially used for printing graphic infor...

Problems solved by technology

[0002] Print graphic information on bottle caps of bottled beverages and alcoholic beverages to achieve labeling or anti-counterfeiting effects. If the graphic information is directly printed on the bottle caps, it will easily pollute the beverages or alcoholic beverages in the bottle

[0003] At present, the bottle caps of bottled beverages and wines are usually equipped with a gasket to enhance the sealing effect. Such bottle gaskets usually do not have any information attached, although it is conceivable to print the above-mentioned graphics or anti-counterfeiting information on the bottle gasket. However, it is still difficult to avoid the problem of contamination of beverages or wine in the bottle

[0004] For this reason, the applicant has developed a bottle pad specially used for printing graphic information, which can not only achieve the sealing effect, but also play the role of marking or anti-counterfeiting. This type of bottle pad includes a base material layer and an outer film layer, and the outer film layer has It is made of transparent material and its bottom surface is printed with graphic information. The outer film layer is set on the base material layer by gluing or composite process to form the main body of the bottle mat. The outer film layer can isolate the contact between the beverage or wine in the bottle and the graphic information pattern. , but in the actual production process, both the base material layer and the outer film layer are roll materials, which are stored in rolls and sent out as a whole. Cut to the specified bottle pad shape, and the base layer is usually made of deformable foam material (so as to compress and deform the bottle cap), the outer film layer is a transparent film, and the thickness of the outer film layer is much smaller than the thickness of the base layer , the materials of the two are different, the tension and deformation are different during winding and bending, and due to the large thickness difference, the outer film layer and the base layer are prone to misalignment and wrinkling during the winding process, which affects the bonding Or compound effects, even unable to read graphic information, high scrap rate

[0005] Of course, in order to avoid winding and wrinkling, the thicker gasket can be compounded by unwinding the coil, and then the thicker gasket is output as a whole, and finally die-cut to the specified contour, although this method avoids the need for composite gaskets. Problems caused by winding, but in this way, the production efficiency is extremely low, and it takes up a lot of space, and the production line layout is extremely inconvenient
