Description

Novel Easy tearing lid and its belling device

Technical field

It can increase the novel Easy tearing lid of Easy tearing lid bearing capacity and its belling device the utility model is related to a kind of, belong to Easy tearing lid manufacturing field.

Background technology

Existing Easy tearing lid, as shown in Figure 1, including metal decorative cover 1 ' and the aluminium foil 2 ' being pressed together on metal decorative cover 1 ', and 3 ' upper surface of aluminium foil nip portion in metal decorative cover 1 ' is flat, when cover bottom bears an air pressure（In Easy tearing lid tank When head is transported to area more higher than grown place temperature, the pressure in Easy tearing lid can increase）, lid aluminium foil will encircle It rises, lid aluminium foil the phenomenon that it is detached with lid will easily occur so that product cannot be eaten when polluting or go bad, so as to improve The scrappage of product.

Utility model content

Purpose of design：To avoid the deficiency in background technology, design is a kind of can to increase the novel of Easy tearing lid bearing capacity Easy tearing lid and its belling device.

Designing scheme：To realize above-mentioned purpose of design.1st, the outer surface of the horn-like sheet body is the design of arcwall face, is One of the technical characteristics of the utility model.The purpose designed in this way is：When cover bottom bears an air pressure（In Easy tearing lid When can is transported to area more higher than grown place temperature, the pressure in Easy tearing lid can increase）, lid aluminium foil will encircle It rises, when the peeling force that lid aluminium foil is caused to arch upward is more than lid aluminium foil bonding force, lid and aluminium foil will be stripped, so as to make The product rejection is obtained, the outer surface of horn-like sheet body is concave curved surface, changes the loading angle of aluminium foil, can substantially increase The bearing capacity of lid, so as to reduce product scrappage caused by the temperature difference.2nd, the crimping upper surface is less than horn-like sheet body Upper surface design, be the two of the technical characteristics of the utility model.The purpose designed in this way is：In lid aluminium foil and lid Lid aluminium foil will appear after heat-seal bond deforms by a small margin, by carrying out pushing processing to intermediate aluminium foil（Under intermediate aluminium foil It is recessed）, aluminium foil is enabled to be in tensioned state, so as to which the aluminium foil being arranged on metal decorative cover be made to seem well-pressed, less than horn-like sheet body Crimping plays the role of limited support for recessed aluminium foil, so that it is guaranteed that the processing quality of Easy tearing lid.3rd, the aluminium foil side is set There is the design of knob, be the three of the technical characteristics of the utility model.The purpose designed in this way is：Knob is convenient for user by aluminium Foil is torn from metal decorative cover.4th, it is arc that the lower face of the belling upper mold, which is provided with circular groove and the internal face of circular groove, The design in face is the four of the technical characteristics of the utility model.The purpose designed in this way is：The internal face of circular groove is arc Face, in this way after the pressing effect by belling upper mold and belling lower die, in the aluminium foil nip portion shape of the metal decorative cover of Easy tearing lid Into horn-like sheet body, and the outer surface of horn-like sheet body is arcwall face.5th, the lower face of belling upper mold is provided with annular groove and ring The outer side surface of connected in star is the design of arcwall face, is the five of the technical characteristics of the utility model.The purpose designed in this way is： The outer side surface of annular groove is arcwall face, in this way after the pressing by belling upper mold and belling lower die, in the gold of Easy tearing lid The aluminium foil nip portion for belonging to decorative cover forms horn-like sheet body, and the outer surface of horn-like sheet body is arcwall face, while can be to aluminium foil Middle part carries out pushing processing.6th, the bottom plate upper surface in the belling lower die is equipped on the outside of round fixed block and round fixed block and sets There is the design of movable sleeve block, be the six of the technical characteristics of the utility model.The purpose designed in this way is：Belling lower die is lifting It is moved upwards under the promotion of platform and belling processing, wherein movable sleeve block and the cooperation pair of belling upper mold is carried out to Easy tearing lid with belling upper mold Easy tearing lid plays clamping action, and the round fixed block for continuing uplink carries out belling processing to the aluminium foil nip portion of Easy tearing lid, from And improve the efficiency of Easy tearing lid belling processing.7th, the movable sleeve block upper surface is equipped with the design of limit stop ring, is that this practicality is new The seven of the technical characteristic of type.The purpose designed in this way is：Limit stop ring plays positioning action to Easy tearing lid.8th, it is described round solid Determine the design that block upper surface is provided with annular groove, be the eight of the technical characteristics of the utility model.The purpose designed in this way is：It is described Round fixed block upper surface is provided with annular groove, and annular groove can prevent from Easy tearing lid crimping from occurring deformation in belling processing procedure asking Topic.9th, the belling upper mold lower face is equipped with decorative pattern, and the circle fixed block upper surface is equipped with the design of decorative pattern, is that this practicality is new The nine of the technical characteristic of type.The purpose designed in this way is：The belling upper mold lower face is equipped with decorative pattern, the circle fixed block Upper surface is equipped with decorative pattern, and such belling device presses the aluminium foil on Easy tearing lid while belling processing is carried out to Easy tearing lid Flower processing.

Technical solution one：A kind of novel Easy tearing lid, including metal decorative cover and the aluminium foil being pressed together on metal decorative cover, the gold Belong to the aluminium foil nip portion of decorative cover by be in integrally-built ring slice and horn-like sheet body form and the internal circle of ring slice with The outer circumferential edge connection of horn-like sheet body, the outer surface of the horn-like sheet body is concave curved surface.

Technical solution two：A kind of novel Easy tearing lid belling device, including belling upper mold and belling lower die, the belling upper mold Lower face be provided with the internal face of circular groove and circular groove and be provided with ring for the lower face of evagination arcwall face or belling upper mold The outer side surface of connected in star and annular groove is evagination arcwall face；The belling lower die is located at immediately below belling upper mold and under belling Mould position bottom plate is mounted on the upper surface of lifting platform.

The utility model is compared with background technology, and novel Easy tearing lid and its belling device are by changing the shape of aluminium foil nip portion Shape realizes increase Easy tearing lid bearing capacity, so as to reduce product scrappage caused by environmental factor.
