Description

A plastic bottle body with high structural strength

【Technical field】

The utility model relates to a plastic bottle, in particular to a plastic bottle body with high structural strength.

【Background technique】

At present, plastic bottles are widely used in the market, especially in the beverage filling industry. The plastic bottle body is generally blow-molded, that is, the blank is put into a mold with a cavity and blown to form it. The current molds are combined with the front and rear molds to enclose the cavity, so the blow-molded plastic bottle will be in the A parting line appears at the parting surface where the front and rear molds meet, and the parting line is where the structural strength of the plastic bottle is weak, especially at the parting line in the middle of the bottom of the plastic bottle, where the structural strength is the lowest. When the plastic bottle is filled with liquid, due to the pressure of expansion in the plastic bottle, cracking is prone to occur at the parting line at the bottom of the plastic bottle during long-term storage, causing the liquid in the bottle to spill out and the plastic bottle to be damaged , Bringing huge economic losses to beverage producers.

Therefore, the present invention just produces based on above deficiency.

【Content of utility model】

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a plastic bottle body with simple structure and high structural strength.

The utility model is achieved through the following technical solutions:

A plastic bottle body with high structural strength is characterized in that: it includes a bottle body 1 blow-molded by a blow molding machine, and the middle position of the bottom of the bottle body 1 is provided with a groove 2 recessed inwardly. In the groove 2 of the bottle body 1 and on the parting line 101 of the bottle body 1, there is a reinforcing sheet 3 integrally blow-molded with the bottle body 1 for improving the structural strength of the plastic bottle body.

The plastic bottle body with high structural strength as described above is characterized in that: the reinforcing sheet 3 is connected with the groove wall of the groove 2 .

The plastic bottle body with high structural strength as described above is characterized in that the distance between the parting line 101 of the bottle body 1 and the two sides of the reinforcing sheet 3 is equal.

The plastic bottle body with high structural strength as described above is characterized in that: the thickness of the reinforcing sheet 3 is 0.8 mm to 1.5 mm.

The plastic bottle body with high structural strength as described above is characterized in that the groove 2 is an arc groove.

The plastic bottle body with high structural strength as described above is characterized in that the groove 2 is a U-shaped groove.

The plastic bottle body with high structural strength as described above is characterized in that the groove 2 is a through groove spanning the entire bottle body 1 .

Compared with the prior art, the utility model has the following advantages: the middle position of the bottom of the bottle body of the utility model is provided with a groove inwardly recessed, and the groove is located on the parting line of the bottle body and is provided with the bottle body. Integral blow-molded reinforcing sheet used to improve the structural strength of the plastic bottle. The setting of the reinforcing sheet enhances the structural strength of the plastic bottle, making it less likely to crack at the middle of the bottom of the plastic bottle and reducing the economic loss of the user.

【detailed description】

Below in conjunction with accompanying drawing, the utility model will be further described:

A plastic bottle body with high structural strength, including a bottle body 1 blow-molded by a blow molding machine, the middle position of the bottom of the bottle body 1 is provided with a groove 2 recessed inward, and in the groove 2 Inside and on the parting line 101 of the bottle body 1, there is a reinforcing sheet 3 integrally blow-molded with the bottle body 1 for improving the structural strength of the plastic bottle body. The setting of the reinforcement sheet 3 enhances the structural strength of the plastic bottle body, making it less likely to crack in the middle of the bottom of the plastic bottle body, reducing the economic loss of the user.

The reinforcing sheet 3 is connected with the groove wall of the groove 2 . Therefore, there is no gap between the reinforcing sheet 3 and the bottle body 1, and such a structure makes the structural strength of the plastic bottle body higher, making the parting line at the middle position of the bottom of the plastic bottle body less likely to crack.

The distance between the parting line 101 of the bottle body 1 and the two sides of the reinforcement sheet 3 is equal. That is to say, the two sides of the reinforcement sheet 3 are symmetrical with respect to the parting line 101 of the bottle body 1, thus making the structure of the plastic bottle body stronger.

The thickness of the reinforcing sheet 3 is 0.8mm to 1.5mm. Designing the thickness of the reinforcing sheet 3 to be 0.8mm to 1.5mm can not only ensure the structural strength of the plastic bottle body, but also ensure that the cost will not increase due to the use of too many raw materials, so that the plastic bottle body can maintain high structural strength. At the same time, the cost is also very low.

The groove 2 is an arc groove, and the groove 2 can also be a U-shaped groove. The groove walls of the arc-shaped groove or the U-shaped groove are all smooth surfaces, which will not cause stress concentration due to the appearance of right angles, so it will not be easy to crack at right angles due to the existence of stress concentration.

The groove 2 is a through groove spanning the entire bottle body 1 . The through groove makes the structure of the plastic bottle body simpler and the cost is also low.
