Background

With the development of packaging materials and packaging techniques, plastic bottles are widely used for packaging cosmetics, washing products, and medicines. At present, most of plastic materials for daily chemical packaging containers, medicine bottles and the like in the market are made of HDPE. HDPE bottles have poor clarity. And transparent plastic bottle can let the people see the article in the packing clearly at a glance, can let the consumer strengthen the sense of trust and the sense of security to the product, consequently the demand to transparent container on the market is more and more wide.

PET as an environment-friendly material has good transparency and glossiness, and has the advantages of good plasticity, impact resistance, size stability, stable chemical property, good gas barrier property, soft touch and the like; meanwhile, through the stretch blow molding process, the capacity range of the PET bottle is wide, and the common capacity range can be from dozens of milliliters to several liters. Therefore, PET bottles are more and more widely used in daily chemical and pharmaceutical packaging fields.

PET bottles are basically sealed by bottle caps, and 80% of PET bottles are used for beverage packaging, and in order to save cost, it is expected that daily chemical and medical PET bottles can be used as common caps for beverage bottles. At present, most daily chemical packaging bottles and medical bottles on the market have only one ring below the bottle mouth threads, and the whole bottle mouth is contained in a bottle cap. The bottle mouth of the beverage bottle is different from the bottle mouth of the beverage bottle, the bottle mouth of the beverage bottle comprises two rings, namely an anti-theft ring (shown in figures 3 and 2-2) and a support ring (shown in figures 3 and 2-3), and the position between the two rings is used for clamping a bottle blank during bottle blowing. By adjusting the shape of the bottle mouth, the bottle cap not only meets the appearance that the daily chemical and medical packaging bottles only have one ring, but also can meet the bottle blowing requirement of PET, and simultaneously can be used as a bottle cap commonly used with the beverage bottle mouth.

SUMMERY OF THE UTILITY MODEL

The utility model discloses select the PET beverage bottle 28mm bottleneck commonly used in the market, on the 28mm bottleneck basis of standard, through the shape of change bottleneck, make it both accord with the appearance of daily use chemical and medical packaging bottleneck, do not influence PET's normal bottle blowing technology again, bottleneck after the while change can also be with the bottle lid of the 28mm bottleneck of standard.

In order to satisfy the above requirements, the utility model discloses a solution is:

providing a 28mm bottle mouth of a PET packaging bottle for daily chemicals and medicines, wherein the outer wall of the bottle mouth is provided with a thread, a groove and a ring from top to bottom in sequence; the thread, the part of the bottle mouth above the thread and the inner diameter of the bottle mouth have the same size as the standard 28mm bottle mouth; the upper end of the groove is 9.6 mm-9.8 mm away from the bottle mouth, and the height is 2.5 mm-2.8 mm; the lower surface of the ring is 14mm away from the bottle mouth.

As a modification, the depth of the groove, i.e. the distance between the bottom of the groove and the root of the thread above it, is 0.5 mm.

As a modification, the height of the bottle mouth, namely the height of the lower surface of the ring from the bottle mouth is 14mm, and the diameter of the ring is 28 mm. The bottle mouth is made of PET plastic.

The utility model discloses a theory of operation: two rings, an anti-theft ring and a support ring are arranged below the thread of the standard 28mm beverage bottle mouth, and the position between the two rings is used for clamping a bottle blank during bottle blowing. Because only one ring is arranged below the design thread of the bottle mouth of the daily chemical and medical packaging bottle, the bottle is changed into PET material, and if the design of the bottle mouth is not changed, a bottle blank is not clamped locally during bottle blowing. The addition of a ring, like a standard 28mm finish, changes the existing design of daily chemical and pharmaceutical packaging finishes. Therefore, the problem of clamping bottle blanks during bottle blowing is solved by adding the groove. According to the requirements of a bottle blowing machine for clamping a bottle blank, the depth of the groove is 0.5mm, and the height of the groove is 2.5 mm-2.8 mm. Because of the sealed inside and outside footpath and the screw thread part that mainly depends on the bottleneck top of bottle lid, in order to can be with the general bottle lid of standard 28mm beverage bottleneck, so the utility model discloses a bottleneck keeps the inside and outside footpath unanimity of screw thread and screw thread above part. In addition, after the standard 28mm beverage bottle is closed, the anti-theft ring is contained in the bottle cap. Because the bottle mouth of the utility model is provided with only one ring (figure 3, 2-3), the ring is contained in the bottle cap, and the ring also has the function of an anti-theft ring, the height of the bottle mouth (figure 1, X) is kept to be close to the height of the anti-theft ring of a standard 28mm bottle mouth, and 14mm is selected; the diameter is also kept close to the anti-theft ring, and is selected to be 28 mm. Compared with a standard 28mm beverage bottle mouth, the bottle mouth has the advantages that the gram weight is reduced by 50%, and materials are saved.

The utility model also provides a bottle, have foretell bottleneck.

Compared with the prior art, the beneficial effects of the utility model are that:

after daily chemical and medical packaging bottles are changed into PET materials, the design that the original bottle mouth of an HDPE bottle is only provided with one ring can be kept, the clamping requirement of a bottle blank during bottle blowing of the PET bottle can be met, and meanwhile, the bottle cap can be shared with the bottle mouth of a standard 28mm beverage. Compared with a standard 28mm beverage bottle mouth, the bottle mouth has the advantages that the gram weight is reduced by 50%, and materials are saved.
