Description

Bottle blank with step opening and draught beer barrel

Technical Field

The utility model relates to the field of bottle blank and draught beer barrel structures.

Background

At present, disposable PET beer barrels are becoming more and more popular in the market, and such PET beer barrels are usually a bottle blank at the initial stage of processing, and the bottle blank is processed into the disposable PET beer barrel by clamping the bottle mouth of the bottle blank, heating and blowing.

However, in practical use, most beer spears of PET beer barrels on the market are sealed in a top sealing mode, but the top sealing mode has the defect that the positions of sealing rings of the beer spears and bottle openings (tops) in sealing assembly are sanitary dead corners, and the beer spears cannot be washed cleanly all the time and cannot be sterilized, so that complete sanitation cannot be achieved, as shown in fig. 1. Therefore, in order to solve the sanitary problem, manufacturers have changed the sealing mode into a side sealing mode, so as to solve the problem of the sanitary dead angle of the sealing ring, as shown in fig. 2. However, in this way, the form of side seal will bring great trouble to the assembly, in the actual assembly process, when the wine lance inserts the bottleneck, because it is side seal, so the sealing washer has just had certain compression capacity at the bottleneck, make it just begin compression atress at the bottleneck, until the wine lance installs in place (the wine lance installs in place and means that the inside neck outside the wine lance is blocked with the first muscle atress of bottleneck), this section is in compression atress state all the time apart from the sealing washer, so assemble very labouriously, operating personnel need keep great pushing down the pressure and force the sealing washer long stroke of walking downwards, not only waste time and energy, still easily crush the sealing washer, appear the problem of sealed inefficacy, as shown in fig. 3.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems, the utility model provides a bottle blank with a step opening and a draught beer barrel, which can effectively solve the problems of high assembly difficulty of a sealing ring and easiness in damage of the sealing ring in the assembly process on the premise of realizing side sealing.

The technical scheme of the utility model is as follows: the bottle blank 1 is provided with a bottle opening 10, and the inner wall of the bottle opening 10 is in a step shape with a large outer part and a small inner part, so that a step opening is formed at the bottle opening.

The inner wall of the bottle mouth 10 is sequentially divided into an outer ring surface 101 and an inner ring surface 102 from outside to inside, the inner diameter of the inner ring surface 102 is smaller than or equal to the outer diameter of the sealing ring 4, and the inner diameter of the outer ring surface 101 is larger than that of the inner ring surface 102.

The bottle blank comprises a bottle blank body 1 and is characterized in that a bottle opening 10 of the bottle blank body 1 is matched with a wine lance 3, a slot 30 used for containing the bottle opening is formed in the wine lance 3, a sealing ring 4 is fixedly arranged on the side wall of the slot 3, and the distance between the sealing ring 4 and the bottom of the slot 30 is larger than the axial length of an outer annular surface 101.

The draught beer barrel 2 is formed by blow molding of the bottle blank 1, and the structure of the barrel opening of the draught beer barrel 2 is consistent with that of the bottle opening of the bottle blank 1.

The utility model greatly facilitates the assembly of the wine lance on the production line, and effectively solves the problems of high assembly difficulty of the sealing ring and easy damage of the sealing ring in the assembly process on the premise of solving the problem of sanitary dead angles of the sealing ring through side sealing. The wine spear has the advantages of exquisite structure, convenience in processing, easiness in realizing the assembly of the wine spear and the like on the whole, and has the advantages of good sealing effect, no sanitary dead angle and the like after the wine spear is assembled.

Detailed Description

In order to clearly explain the technical features of the present patent, the following detailed description of the present patent is provided in conjunction with the accompanying drawings.

As shown in figures 1-5, the bottle blank 1 is provided with a bottle mouth 10, and the inner wall of the bottle mouth 10 is in a step shape with a large outside and a small inside, so that a step mouth is formed at the bottle mouth.

The bottle mouth is clamped in the process of blowing the bottle blank into the draught beer barrel through the bottle blowing machine, so that the structure of the barrel mouth of the draught beer barrel after the blowing is finished is consistent with that of the bottle mouth of the bottle blank. Thus, as shown in fig. 4-6, the sealing ring can be forced past the outer annular surface with a small pressure during the assembly of the wine lance, i.e. so that the sealing ring for the side seal can easily enter the mouth of the bottle.

As shown in fig. 5, when the clamping groove outside the wine spear and the first rib of the bottle opening are pushed to the position needing to be stressed and pressed downwards, the sealing ring is just positioned at the step opening. At this moment, as long as a little effort again, the inside neck of wine lance outside can the atress block with the first muscle of bottleneck, and the sealing washer also installs in place simultaneously, and the pressurized stroke is shorter, as shown in fig. 6, like this, will be very big on the production water line the assembly of wine lance of having made things convenient for. Therefore, on the premise of solving the problem of sanitary dead angles of the sealing ring through side sealing, the problems that the assembly difficulty of the sealing ring is high and the sealing ring is easy to damage in the assembly process are effectively solved.

While the utility model has been described in terms of its preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model.
