Description

The easy-to-pull explosion-proof bottle cap

Technical field

The utility model relates to a kind of bottle cap.

Background technology

For many years, what use for beer bottle is " crown plug " always, though this bottle cap good seal performance, moulding easily, cost are low, it is very inconvenient to open, use the Bottle opener of special use or use other tamper tool.Do not do a good job also easy damage bottleneck and the glass slag is fallen in the bottle when opening, some also can stave finger.For beer bottle, Yin Qinei has certain pressure, in hot weather or transportation, move, vibration takes place in the liquid when opening in the bottle and pressure sharply raises, and the bottle explosion accident often occurs, brings unnecessary damages and loss for customer or manufacturing enterprise.Although minority producer is based on " pop can ", produced the glass bottle lid of the carrying liquid of easy-to-draw, explosion proof type, but owing to draw when the unreasonable gas leakage that produces of structure design complicated, product itself of manufacturing process and frock, uncork lid mouthful fracture at place must be, thereby make customer and use producer less to this approval again with defectives such as bottle opener secondary openings.Also have some producers that this class is easy to generate interior liquid of pressing and adopt " pop can " splendid attire, but, generally do not adopted by manufacturer owing to pop can manufacturing process complexity, apparatus expensive, material requirements height, cost height.

The content of utility model

The technical problems to be solved in the utility model is: overcome the deficiency of existing bottle cap, and provide a kind of easy unlatching and can self-relieving easy-to-pull explosion-proof bottle cap when pressure of the inside of a bottle raises.

Technological improvement of the present utility model is: being the last draw ring afterbody of one with bottle cap body is connected with indentation line on the bottle cap body, is provided with the attached of relief hole and covers between bottle cap body and rubber cushion.

Further technological improvement of the present utility model is: the attached relief hole that covers is positioned at below the indentation line of bottle cap body, and the center of attached lid is the concave station structure.Relief hole is an arc-shaped through-hole.

Compared with prior art, good effect of the present utility model is: owing to increased draw ring on traditional bottle cap, do not need special-purpose bottle opener or other instrument when opening, make uncork be more prone to, more bottleneck can not staved or injures staff.Also because be provided with and the corresponding relief hole in bottle cap body indentation line position attached covering, will be when gaseous tension in the bottle surpasses its rated value with rubber cushion jack-up, and by relief hole the indentation line on the bottle cap body is backed down and to make the pressure of the inside of a bottle automatic release, reach safety, explosion-proof purpose, the person that has also guaranteed the customer simultaneously preserves from and reduces the loss of manufacturing enterprise.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model mainly is to be made of the bottle cap body 1 that has draw ring 4, the attached lid 2 that is provided with relief hole 8.Described draw ring 4 and bottle cap body 1 are connected as a single entity by Sheet Metal Forming Technology, and the centre of draw ring 4 is a hollow form.Be provided with two indentation lines 5 of gradually opening shape on the bottle cap body 1 of draw ring 4 afterbodys, 5 one of this indentation lines extend on the base of bottle cap body 1 always, and another then only extends to the edge on plane on the bottle cap body 1.As shown in Figure 3, Figure 4, described attached lid 2 is to be close to the structure that centre in the bottle cap body 1 has concave station, so that point and can stretch into when pulling moving draw ring 4.Be provided with an arc relief hole 8 on attached lid 2 plane on one side, this relief hole 8 runs through the above and below of attached lid 2, relief hole 8 be arranged on bottle cap body 1 indentation line 5 below.Has the rubber cushion 3 that seals again 2 times at attached lid.

Said bottle cap body 1, attached lid 2 and rubber cushion 3 are combined into one, and can utilize existing capping machine that bottleneck is sealed, and its sealing effectiveness and existing " crown plug " are identical.

Only with hand points to the direction pulling draw ring 4 of indentation line 5 during uncork, and make an indentation line 5 thorough drawing cracks that connect with bottle cap body 1 base, another indentation line 5 is the edge (thoroughly not drawing logical) on drawing crack plane to the bottle cap body 1 then, at this moment draw ring 4 is upwards mentioned and like a cork bottle cap to be opened, without any need for opener, very convenient.As in the higher occasion of ambient temperature, or when transporting, moving, open the appearance vibration, pressure of the inside of a bottle sharply raises, and its high pressure gas then can be with rubber cushion 3 jack-up, and discharge indentation line 5 tops are split by relief hole 8 and discharge bottle cap body 1, can play safety, explosion-proof effect.

Claims (3)

1, a kind of easy-to-pull explosion-proof bottle cap, comprise bottle cap body (1), draw ring (4) and rubber cushion (3), it is characterized in that being connected with indentation line (5) on the bottle cap body (1) for the draw ring of one (4) afterbody with bottle cap body (1), the attached lid (2) that is provided with relief hole (8) is positioned between bottle cap body (1) and the rubber cushion (3).
