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
Technical field
The present invention relates to when the unlatching cover, put in easily the jar of the use seesaw type pulling plate cover of finger.
Background technology
Existing cover is because pulling-on piece and capping are closely pasting, and finger is difficult to enter when therefore opening.
Existing pulling-on piece cover, pulling-on piece is because outer thereby left rotation and right rotation are opened very difficult sometimes.
In addition, at beer, contain under the situation of beverage of carbonic acid gas etc. since jar in the thing expansion can cause upwards drum of lid, from physical angle, the pulling-on piece that is designed to the seesaw shape is impossible.And, when pulling-on piece is the seesaw shape, might influence with drink the mouth join upwarp the part an intensity.
Existing pulling-on piece cover because pulling-on piece and capping closely pasting, is pointed when opening jar and is difficult to enter.
Summary of the invention
The present invention will be arranged on the cover center pulling-on piece make tip-tilted seesaw shape with drinking mouthful joining part and finger entering part not influencing under the folded situation of cap rock, make between itself and the capping and produce the gap, make finger be easier to put in.
By with rivet portion from lid projection upwards, making ellipse in the circular dimension scope at present, can prevent the pulling-on piece left-right rotation.
Number place's flange is set on capping, and capping drum upwards makes the design of seesaw shape pulling-on piece say it is possible physically in the time of can preventing like this that thing expands in beer etc. jar.
For increasing and drink the intensity that upwarps part of the pulling-on piece of mouthful joining part, the both sides of rivet portion make darker as far as possible, do not bend two or three layers laterally with not cutting off.
Pulling-on piece rotation prevent with projection be the pulling-on piece central authorities rivet portion of lid laterally be provided with circular hole, make about the high 0.5～1.0mm in plane of the aspect ratio bore portion that protrudes from capping to be provided with, or protruding top riveted, rotate preventing really.

The specific embodiment
Be riveted on cover central authorities pulling-on piece drink mouthful pressure part and the finger entering part is made tip-tilted seesaw shape, when depressing and drinking mouthful joining part with finger, it is big that the gap of the finger entering part of opposite side becomes, and therefore makes to point to be easy to enter.
The circular protrusions that makes progress from capping of riveting portion is made ellipse in the same size, to prevent the pulling-on piece left-right rotation.
The dark as far as possible flange in number place is set, to prevent causing drum on the capping owing to thing in the jar expands on capping.Make the design of pulling-on piece become possibility physically.
For increasing the intensity that pulling-on piece upwarps part, the both sides of the pulling-on piece of riveting portion are not cut off ground bending laterally, overlapping two-layer or three layers, to increase the intensity of pulling-on piece.
Rotation for preventing from really to be caused by the junction of cover pulling-on piece etc. is provided with the hole on the horizontal pulling-on piece of central riveting portion, the height of the bossing on the capping is provided with on highland, unobstructive scope internal ratio pulling-on piece plane, and maybe rivet on the top of the projection that will be provided with.
Embodiment
With reference to drawing embodiment is described.
Fig. 1 is the block diagram of seesaw type pulling plate cover of the present invention.Being designed to the rivet portion is the tip-tilted seesaw shape in the left and right sides, center, makes it to form the gap with capping.
The block diagram that Fig. 2 stacks for seesaw type pulling plate of the present invention.In not influencing the folded scope of cap rock, form the shape that upwarps.
The figure of Fig. 3 when on pulling-on piece of the present invention, finger being pressed.
Fig. 4 is the section drawing of pulling-on piece capping of the present invention.The darker flange in number place is set, to prevent upwards drum of lid on the capping about pulling-on piece.
Fig. 5 is the planar view of pulling-on piece of the present invention.The part from covering projection that to be riveted is made ellipse, to prevent left-right rotation.
Fig. 6 is the block diagram that pulling-on piece of the present invention strengthens part.Oblique line face shown in Figure 5 is not cut off ground bending laterally.
Fig. 7 prevents to use the block diagram of protuberance for pulling-on piece rotation of the present invention.
Fig. 8 is a block diagram of the present invention.
The present invention implements by the mode of above explanation, can obtain following effect.
By pulling-on piece is made seesaw type, when opening jar, can easily finger be put in.
Can prevent to make out jar not have obstacle because the pulling-on piece that external cause causes rotates.
Count the darker flange in place owing on capping, be provided with, can prevent from upwards to rouse owing to the capping that thing expansion in the jar causes.Make the possibility that is designed to of seesaw type pulling plate.
For preventing to be arranged on the pulling-on piece left-right rotation on the cover, the shape from covering projection of rivet portion is made ellipse or polygon.
Claims (2)
1, a kind of jar that uses the seesaw type pulling plate cover, it is characterized in that, with be arranged on pulling-on piece on the cover with drink mouthful joining part and pull-up part, in not hindering the folded scope of cap rock, make the shape that upwarps along the length direction seesaw shape of pulling-on piece, between capping and pulling-on piece, form the gap; A plurality of outstanding flanges are set, so that suppress downwards owing to a jar interior expansion causes upwards drum of lid on the capping corresponding to the position of leaving the pulling-on piece breadth; With the both sides of pulling-on piece under the prerequisite of not cutting off as far as possible in outside bending so that increase pulling-on piece with drink the intensity that upwarps part that mouth joins; The riveting portion of pulling-on piece central authorities laterally establish the hole, projection is set on capping so that prevent the rotation of pulling-on piece, under unobstructive situation, be provided with projection than pulling-on piece plane height at Width, make the teat of the hole of above-mentioned pulling-on piece and above-mentioned capping chimeric.
