Abstract

The invention makes a pull tab on a can lid to be caught easily by a finger tip at opening a can by forming the pull tab in a seesaw-like shape. The pull tab provided at the can lid is formed in a seesaw-like shape with its one part facing a spout and the other part for pulling-up warped upward with a part caulked at the center of the tab made to serve as a center, and a gap is formed between the pull tab and the can lid, With the part facing the spout pressed by a fingertip at the time of opening the can, a large gap is formed between the part at the opposite side of the tab and the lid surface, and thereby the finger tip can be easily put into the gap. A part protruding beyond the lid at a riveted portion is formed in an oval shape within the size of conventional circular shape, or a protuberance projecting higher beyond the plane of the tab is provided at the side of the caulked part, and thereby the tab is prevented from turning. Furthermore, with deep rims provided at several positions on the lid surface, bulging arising from a swell inside the can is prevented and thereby such a type of pull tab can be physically set on a can for carbonated drinks such as beer or cola.

Description

Cans with rocker pull-tab can lids

technical field

The present invention relates to a can with a seesaw type pull-tab can lid which is easy for fingers to penetrate when opening the can lid.

Background technique

In the existing can lid, since the pull tab is closely attached to the lid surface, it is difficult for fingers to enter when the lid is opened.

In the existing pull-tab tank lid, sometimes the pull-tab rotates left and right due to external factors, making it difficult to open.

In addition, in the case of beer, beverages containing carbonated gas, etc., since the expansion of the contents of the can will cause the lid to bulge upward, it is physically impossible to design a rocker-shaped pull tab. Moreover, when the pull piece is in the shape of a seesaw, it may affect the strength of the upturned part connected to the drinking mouth.

In the existing pull-tab can lid, since the pull-tab is closely attached to the lid surface, it is difficult for fingers to enter when opening the can.

Contents of the invention

In the present invention, the part of the pull tab arranged in the center of the can lid that is in contact with the drinking port and the finger entry part is made into an upwardly warped seesaw shape without affecting the lamination of the lid, so that a gap is formed between it and the lid surface, so that Fingers are easier to reach in.

By changing the upward protrusion of the rivet part from the cover to an oval shape within the current circular size range, the pull tab can be prevented from turning left and right.

Several flanges are arranged on the cover surface, which can prevent the cover from bulging upwards when the content in the can such as beer expands, so that the design of the seesaw-shaped pull piece is physically possible.

In order to increase the strength of the upturned part of the pull piece connected to the drinking mouth, the two sides of the rivet part should be made as deep as possible, and two or three layers should be bent outward without cutting.

The tab rotation prevention protrusion is provided with a circular hole in the lateral direction of the central rivet part of the cover, so that the height of the protrusion from the cover surface is about 0.5 to 1.0 mm higher than the plane of the hole part, or the protrusion The upper part is riveted to securely prevent rotation.

Explanation of symbols: 1. Can lid; 2. Pull tab; 3. Rivet part; 4. Oval protrusion; 5. Diagonal line part (bending part); 6. Flange; Rotation prevention protrusion.

Detailed ways

Make the pressing part of the drinking port and the finger entry part of the pull piece riveted in the center of the can lid into an upturned rocker shape. When the part connected to the drinking port is pressed down with your finger, the finger on the other side enters the gap of the part Larger, thus allowing easy access for fingers.

Make the round protrusion upward from the cover surface of the riveted part into an oval shape within the same size to prevent the pull tab from turning left and right.

Set several flanges as deep as possible on the cover surface to prevent the cover surface from bulging due to the expansion of the contents of the tank. Make the pull tab design physically possible.

In order to increase the strength of the upturned part of the pull-tab, the two sides of the pull-tab of the riveted part are bent outward without cutting, and two or three layers are overlapped to increase the strength of the pull-tab.

In order to prevent the rotation caused by the connection of the can lid pull tab, etc., a hole is provided on the pull tab in the transverse direction of the central riveting part, so that the height of the raised part on the cover surface is set higher than the plane of the pull tab within a non-obstructive range. Or riveting the raised upper part of the set.

Example

Examples will be described with reference to the drawings.

Fig. 1 is a perspective view of a seesaw type pull-tab can lid of the present invention. It is designed in the shape of a seesaw with the rivet part as the center, which upwards from left to right, so that it forms a gap with the cover surface.

Fig. 2 is a perspective view of stacked seesaw pull tabs according to the present invention. The upturned shape is formed within the range that does not affect the lid lamination.

Fig. 3 is a view when pressing a finger on the pull tab according to the present invention.

Fig. 4 is a cross-sectional view of the cover surface of the pull-tab according to the present invention. Several deep flanges are arranged on the cover surface on the left and right sides of the pull tab to prevent the cover from bulging upwards.

Fig. 5 is a plan view of the pull tab of the present invention. Make the riveted part that protrudes from the cover oval to prevent it from turning side to side.

Fig. 6 is a perspective view of the reinforced part of the pull tab according to the present invention. Bending the oblique surface shown in Fig. 5 outward without cutting.

It is a perspective view of the convex part for handle rotation prevention which concerns on this invention.

Fig. 8 is a perspective view of the present invention.

The present invention is carried out in the manner described above, and the following effects can be obtained.

By making the pull tab rocker-like, it is easy to put your fingers in when opening the can.

It can prevent the pull tab from rotating due to external factors, so that there is no obstacle to opening the can.

Since several deep flanges are arranged on the cover surface, the upward bulging of the cover surface caused by the expansion of the contents of the tank can be prevented. This makes it possible to design a seesaw puller.

In order to prevent the pull piece arranged on the tank cover from turning left and right, the shape of the rivet part protruding from the cover is made into an ellipse or a polygon.
