Abstract

The utility model relates to the improved structure of an easy-open bottle cap, in particular to the structure which is arranged on the bottle cap of a bottle package, and in the structure, the bottle cap can be opened through an easy-open ring without using an opener. The improved structure of an easy-open bottle cap is characterized in that the side part of a middle part of a finished bottle cap is provided with a hollow rivet formed through pressurization and is provided with a radiation spiral main cutting mark through mechanical processing, and the radiation spiral main cutting mark and the centerline of the periphery are tangential; the small hole of an easy-open vertical ring and the shaft body of the rivet are matched; the upper end of the rivet is riveted, a bigger head part is formed and is covered on the periphery of the small hole of the easy-open vertical ring. Accordingly, the easy-open vertical ring can be torn apart along the radiation spiral main cutting mark, and the opening force can be reduced.

Description

Improved structure of easily opened bottle cap

The utility model is a kind of easy-to-pull bottle cap structure-improved, refers to that especially this device of mat can radiate spiral master snick towards removable portion and tear, and is able to the end of openable container easily, and does not need a kind of constructional device by tool for processing such as bottle openers in addition.

Know as known, easily open pull-tab and be widely used in as on drink can, fashion drink and the beer can, though have the minority soda to improve to be used in bottled on, is perfect not to the utmost eventually, through studying in great detail, nothing more than following shortcoming is arranged:

1. punching out is one-body molded, must stay side draw ring riveted tab, waste material, and cost is too high.

2. hang down circle in the lower end,, must grip body with a strength, and bestow big strength and just can tear removable portion when the application of force up the time.

3. when removable portion is applied that big strength removes thereon, often cause the impact shock of bottle or rock, make content thereby spill.

4. the bottleneck side has a vertical circle design, destroys overall appearance.

5. hanging down of bottleneck side enclosed design, easily colludes with other thing when general carrying, brings inconvenience, and when a large amount of carrying, also needs other with the container splendid attire in addition, just can move, and also be inconvenience.

Therefore, the purpose of the utility model is to provide a kind of structure-improved of easy-to-pull bottle cap, and it can overcome above-mentioned shortcoming, reduces crack force, and saving in material is aesthetic in appearance, is convenient to carrying, meets economic benefit.

Above-mentioned purpose reaches by following structure.The structure-improved of this a kind of easy-to-pull bottle cap, it is made up of bottle cap body, the easy-to-pull circle institute of hanging down, and its improvements are,

Bottle cap body, empty rivet stem body among the center side end is provided with a press molding, is provided with a small circular embossing and is provided with radiation spiral master snick as the center with the hollow rivet handle, its another spiral master snick is reserved spacing from the circumferential edge end, in order to the unlatching of tearing of integral body;

The easy-to-pull circle that hangs down is established a finger pull-up and is inserted the hole, establishes a flange in leading edge, and its central authorities establish an aperture, cooperates empty rivet stem body among the bottle cap body to form an enlarged head through riveted and covers and be pressed on easy-to-pull and hang down on the aperture Zhou Yuan of circle;

The combination of mat said structure makes it can tear bottle cap, simple operation more easily.

Brief description:

The block diagram of structure is commonly used by Fig. 1 system.

The embodiment of structure commonly uses in Fig. 2 system.

The expansion drawing of structural plan is commonly used by Fig. 3 system.

Fig. 4 is the three-dimensional system diagram of the utility model.

Fig. 5 is the stereo appearance figure of the utility model.

Fig. 6 is the plane outspread drawing of the utility model.

Fig. 7 is the embodiment of the utility model.

From commonly using Fig. 1 of structure, 2,3, just can know and finding out vertical vertical 90 ° of the covering of enclosing into, when the application of force from lower to upper during the application of force, must grip bottle end with another hand, and bestow a strength greatly, could open, therefore often cause bottle to impact or vibration, make content thereby spill, adding man-hour again is a whole punch forming because of hang down circle and bottle cap, waste material very, the utmost point are not had an economic benefit and open on the effect yet relatively poor.

See also Fig. 4, the utility model mainly is made of

bottle cap body

1,2 on the vertical circle of easy-to-pull; Wherein:

Bottle cap body 1, empty rivet stem body 11 among the center side end is provided with a press molding is the center with hollow rivet handle body 11, is provided with a small circular embossing 111 and is provided with radiation

spiral master snick

12,13, spiral master snick 12 is reserved A part spacing from the circumferential edge end, in order to the unlatching of tearing of integral body;

The easy-to-pull circle 2 that hangs down is established a finger pull-up and is inserted hole 21, establishes a flange 22 in leading edge, and its central authorities establish an aperture 221, cooperates empty rivet stem body 11 among the bottle cap body 1 to form an enlarged head through riveted and covers and be pressed on easy-to-pull and hang down 221 week of aperture of circle 2 on the circle;

It is when when assembling, and as shown in the figure, hang down circle 2 of easy-to-pull changes in the centre of bottle cap body 1 for the small circular embossing 111 of its side setting of center along rivet stem body 11;

It uses method of operation figure as 5, shown in 6, with the vertical circle 2 of easy-to-pull, go to opening point (as shown in Figure 6) outside the bottleneck along rivet stem body 11 for small circular embossing 111 cws of its side of center, omiting Shi Yili again, is fulcrum with the riveted place, through opening a duck eye, carry over radiation spiral master snick 12 its removable portions again and tear, just can open and only use slight strength swimmingly and just can easily open its next (as shown in Figure 7).

The advantage of the utility model:

1. reduce to open the strength of bestowing, use just tearing type bottle cap easily of slight strength.

2. saving material, handling ease meets economic benefit.

3. it is easy, convenient to open, and applicability is wider.

4. elegant in appearance in the global design, also do not take up space.

5. when carrying in a large number, can not need the container splendid attire, get final product work with the binding mode.

In sum, the utility model is when running, really can reach and reduce crack force and utilize less strength just can tear bottle cap easily, really have and open easy, convenient effect, and its structural shape does not all have and sees any similar open person, really meet the condition of utility model patent, so file an application in accordance with the law, request is ratified to be lotus.
