Abstract

The utility model discloses a novel easy-open metal crown lid including a lid top and a skirt edge; a pull ring is covered on the upper end face of the lid top, a connecting piece compounded on the upper end face of the lid top extends at one side of the pull ring, and the inner side surfaces of the skirt edge at the two sides of the axis of the pull ring are respectively provided with a notch line. The lid has the characteristics of convenient opening and automatic pressure release, moreover, the integral rigidity and intensity of the lid body can be improved, and the length of the metal plates for making the lid body is reduced, therefore, the lid saves materials, reduces the manufacturing cost, and is applicable to the beer industry.

Description

Novel easy-to-draw crown plug

Technical field

The utility model relates to a kind of crown plug, is specifically related to a kind of novel easy-to-draw crown plug.

Background technology

At present, most of beer, beverage, seasonings all adopt the crown plug structure with the bottle cap of glass bottle.But there is following shortcoming in present crown plug structure: 1, crown plug is inconvenient to open, and must could open by the uncork special implement; 2, when gases such as glass bottle content carbonated, if the bottle internal gas pressure reaches the critical pressure force, then glass bottle has the possibility of blast, has also influenced the content quality simultaneously; 3, copy easily, producer is caused damage; 4, existing crown cork rigidity and intensity are lower, and the iron plate of employing is thicker, waste material.

The utility model content

The purpose of the utility model is the weak point to prior art, and a kind of novel easy-to-draw crown plug simple in structure is provided, and it opens convenient, and can releasing pressure automatically.

For achieving the above object, the utility model adopts following technical scheme:

Novel easy-to-draw crown plug comprises caping and shirt rim; The upper surface of said caping covers a draw ring, and the side extension one of said draw ring is compound in the connecting strap of caping upper surface, and is respectively equipped with a kerf line at the medial surface of draw ring axis two side shirt edges.

As preferably, the covering position of the corresponding draw ring in said caping upper surface is provided with an annular groove, and said draw ring is placed in this annular groove.

Further preferred, the cross-sectional plane of said annular groove is a rectangle.

Further preferred, said annular groove is provided with half the heavy portion in the zone that the caping upper surface is enclosed.

As preferably, said connecting strap extends to shirt rim and compound with this shirt rim, place from the caping upper surface.

As preferably, the angle between said two cut line is 120 degree.

The utility model has and opens convenient, self-relieving characteristics, and can improve the integral rigidity and the intensity of lid through adopting said structure, reduces lid and manufactures the thickness with sheet metal, has saved material, has reduced manufacturing cost.

Description of drawings

Fig. 1 is the sectional structure scheme drawing of the utility model.

Fig. 2 is the plan structure scheme drawing of the utility model.

Among the figure:

1-caping; 11-annular groove; 12-half heavy portion; 2-shirt rim; 21-cut line; 3-draw ring; 4-connecting strap.

Combine accompanying drawing and embodiment that the utility model is done further explain at present.

The specific embodiment

As depicted in figs. 1 and 2, the described novel easy-to-draw crown plug of the utility model mainly is made up of caping 1, shirt rim 2, draw ring 3 and connecting strap 4.The annular groove 11 that it is rectangle that the upper surface of caping 1 is provided with a cross section is provided with one and half heavy portions 12 in the zone that annular groove enclosed.Draw ring 3 covers the upper surface of caping 1 and is placed in this annular groove 11.Connecting strap 4 extends from a side of draw ring 3, and extends to shirt rim 2 from caping upper surface 1, and this connecting strap is combined with each other with the caping upper surface and the shirt rim that are covered.Medial surface at draw ring axis two side shirt edges 2 is respectively equipped with one section cut line 21, and the angle between said two cut line is 120 degree.。

The use of the utility model is following:

Utilize traditional crown plug capping machine the utility model to be pressed onto the bottle mouth position of glass bottle.In the time of need opening bottle cap, with pointing the inward flange that triggers draw ring from half heavy portion of caping, when draw ring becomes an angle of 90 degrees with respect to the caping perk; Forefinger is placed in the draw ring, pull-up backward gently makes draw ring and connecting strap tilt upward again; At this moment because the iron plate attenuate at cut line place; Intensity reduces, and the shirt rim is torn from cut line in the force, thereby easily bottle cap is separated from bottleneck.

When the glass bottle that adopts the utility model to seal is impacted in transportation and handling procedure, when a bottle internal gas pressure is increased to a transformation point (like 0.8Mpa, adjustable), the cut line of the utility model can automatically unloading, reduces the generation of bottle explosion casualty accident.When bottle internal gas pressure during less than transformation point, then the utility model can not leak gas again, makes bottle interior content can not receive very big influence.

Because the caping of the utility model is provided with annular groove, has increased lid whole rigidity and intensity, therefore can adopt thin iron plate or stainless steel materials, saved material.

The utility model is simple in structure, and it is convenient to open, and is specially adapted to the crown plug of beer bottle, and because of not changing the design of bottle cap itself, ability and domestic brewery form a complete production network, and need not improve original bottle cap production facilities.
