Description

Technical Field

[0001] The present invention relates to the technical field of container closure, and particularly relates to an easy-to-open container metal closure that facilitates information acquisition. Background Art

[0002] Currently, the utility model patent with the publication number CN212606890U discloses an easy-to-open bottle cap with a new type of gasket, which includes a bottle cap covering the bottle mouth and a pull ring connected to one side of the bottle cap. The bottle cap includes an outer shell, and a gasket is fixedly installed inside the outer shell. The gasket includes an inner sealing ring and a circular outer sealing ring. The outer sealing ring is fixedly installed on the inner side of the side wall of the outer shell. The inner sealing ring is in a beveled shape like a knife cut, and the long end is close to the pull ring. The inner sealing ring is arranged inside the outer sealing ring.

[0003] In actual production, it is often necessary to print some information on the inner side of the bottle cap, such as lottery information or two-dimensional codes. However, due to the blockage of the gasket, these printed information cannot be clearly presented; but separating the gasket from the bottle cap easily causes the glue on the gasket to take away part of the ink of the two-dimensional code, resulting in incomplete printed information. Summary of the Invention

[0004] The purpose of the present invention is to provide an easy-to-open container metal closure that facilitates information acquisition, and its advantage is that the closure can be easily opened, and at the same time, the printed information can be ensured to be complete, clear and easy to read for scanning.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: an easy-to-open container metal closure that facilitates information acquisition, including a bottle cap and a sealing gasket arranged inside the bottle cap;

[0006] It is characterized in that the bottle cap includes a circular pressing end plate and a gripping edge that grips the edge of the bottle mouth, and the gripping edge extends from the edge of the pressing end plate;

[0007] A bonding layer, an isolation layer and an information recording block are sequentially arranged on the side of the pressing end plate facing the sealing gasket;

[0008] An easy-opening convex edge extends from the edge of the gripping edge. Two symmetrically arranged easy-tearing grooves are opened on the side of the pressing end plate facing away from the sealing gasket, and the easy-tearing grooves extend to both sides of the easy-opening convex edge;

[0009] The information recording block is arranged between the two easy-tearing grooves;

[0010] The bonding layer evenly covers the inner side of the bottle cap, and the isolation layer covers the bonding layer;

[0011] The isolation layer includes a covering block and a connecting block. The connecting block is arc-shaped, and a receiving groove is formed between the two connecting blocks.

[0012] The upper and lower sides of the adhesive layer are respectively adhered to the sealing gasket and the pressing end plate.

[0013] Through the above technical solution, the pressing end cover is used to press the sealing gasket against the bottle mouth, and at the same time, the clamping edge tightly holds the flange of the bottle mouth, so that the sealing gasket can better seal the bottle mouth; the information recording block is used to record information. The isolation layer does not adhere to the sealing gasket, which can better prevent the ink on the information recording block from being taken away when the sealing gasket is separated from the pressing end cover, ensuring the integrity of the information; the adhesive layer is used to adhere the sealing gasket to the pressing end plate, making the installation of the sealing gasket more firm and further providing the sealing performance; the easy-opening convex edge is used to install a pull ring or a convex block for the user to apply force to the bottle cap; the easy-tearing groove extends to both sides of the easy-opening convex edge, and the easy-tearing groove is used to guide the bottle cap to separate from both sides of the easy-tearing groove, making the bottle cap easier to open; the covering block in the isolation layer is used to cover part of the adhesive layer, and the connecting block is used to cooperate with the adhesive layer, thus better preventing the isolation layer from falling out.

[0014] The present invention is further configured such that: the information recording block is located in the upper half of the pressing end cover near the easy-opening convex edge.

[0015] Through the above technical solution, after the pressing end cover is opened by using the easy-opening convex edge, the upper half of the pressing end cover near the easy-opening convex edge will roll up, and at this time, the information recording block will be exposed, enabling the user to more conveniently obtain the information recorded therein.

[0016] The present invention is further configured such that: a triangular guiding notch is formed at the position where the clamping edge is close to the easy-opening convex edge, and the guiding notch communicates with the easy-tearing groove.

[0017] Through the above technical solution, the guiding notch can guide the stress to concentrate at the notch of the easy-tearing groove, making it easier to tear the bottle cap from the easy-tearing groove.

[0018] The present invention is further configured such that: a transition arc edge is provided between the clamping edge and the pressing end plate.

[0019] Through the above technical solution, the transition arc makes the transition between the clamping edge and the pressing end plate smoother, and also avoids the cracking of the easy-tearing groove at the transition.

[0020] The present invention is further configured such that: the side of the connecting block facing the center of the pressing end plate is arc-shaped, and the ends of the two connecting blocks away from the easy-opening convex edge are open.

[0021] Through the above technical solution, the two arc-shaped connecting blocks can embrace both sides of the bonding layer in the connection area with the sealing gasket in an embracing form. At the opening, the bonding layer can contact the sealing gasket, increasing the area of the bonding layer and the sealing gasket, so that the bonding layer can more firmly bond the sealing gasket to the pressing end plate.

[0022] The present invention is further configured that: the isolation layer is formed by uniformly coating emulsified paraffin or is cut from a polypropylene film.

[0023] Through the above technical solution, emulsified paraffin is convenient for coating into a film, and emulsified paraffin does not bond with other substances, which can play a good isolation role; the polypropylene film can also be conveniently covered on the inner side of the bottle cap, and the polypropylene film does not bond with the bottle cap and the sealing gasket, which can play a good isolation role.

[0024] The present invention is further configured that: the sealing gasket includes a base layer, a thickening layer, an outer sealing ring for fitting with the outer side of the bottle mouth, and an inner sealing ring for fitting with the inner side of the bottle mouth, which are integrally formed.

[0025] Through the above technical solution, the base layer is used to carry the thickening layer, the outer sealing ring and the inner sealing ring. The thickening layer can be set in a ring shape. The thickening layer can enhance the overall strength and toughness of the sealing gasket. Setting the thickening layer in a ring shape can save materials as much as possible while ensuring the function; the inner sealing ring and the outer sealing ring are respectively in contact and fit with the outer side and the inner side of the bottle mouth, thereby achieving a better sealing effect.

[0026] The present invention is further configured that: the upper end of the inner side of the inner sealing ring is inclined towards the middle position of the bottle cap.

[0027] Through the above technical solution, when the inner sealing ring is squeezed, the inclined inner sealing ring enables it to better rebound towards the direction of the bottle mouth, so as to fit more tightly at the bottle mouth and further improve the sealing effect.

[0028] The present invention is further configured that: the information recording block is printed with high-adhesion ink, and the high-adhesion ink is divided into the following raw material weight components: 26 - 28 parts of polyurethane resin, 22 - 24 parts of modified alkyd resin, 24 - 26 parts of water-soluble acrylic resin, 3 - 5 parts of mica, 7 - 9 parts of wollastonite, 1 - 3 parts of 783 slow-drying water, 2 - 4 parts of epoxy-methoxy functional silane, 44 - 46 parts of γ-butyrolactone, 32 - 34 parts of turpentine, 3 - 5 parts of sodium hexametaphosphate, and 4 - 6 parts of natural oil.

[0029] Through the above technical solution, epoxy-methoxy functional silane is an adhesion promoter, which can better improve the adhesion of the ink, enabling the information recording block to adhere more firmly to the isolation layer. When the user opens the bottle cap, the sealing gasket, the bottle cap and the isolation layer are all separated. Due to the high adhesion of the ink, the ink can adhere firmly to the isolation layer and will not be carried away by the sealing gasket, further ensuring the integrity of the information recording block.

[0030] In summary, the present invention has the following beneficial effects:

[0031] 1. The isolation layer separates the adhesive layer from the sealing gasket, so that when the bottle cap is opened and the sealing gasket is detached from the bottle cap, it will not carry away the ink on the information recording block along with the adhesive layer, ensuring the integrity of the information recording block;

[0032] 2. The information recording block is located in the upper half of the pressing end cap close to the easy-open convex edge, so that after the bottle cap is torn open through the easy-open convex edge, the information recording block can be presented more completely and clearly.
