Referring to fig. 1, the glass cream bottle comprises a bottle mouth 1 and a bottle body 2 connected to the lower end of the bottle mouth 1, a coherent joint line 3 is arranged on the outer surface of the bottle mouth 1 and the outer surface of the bottle body 2, a positioning nail 4 protruding in the radial direction is arranged on the outer surface of the bottle mouth 1, and the positioning nail 4 is positioned on the joint line 3.

To produce the above-mentioned bottle mouth 1, a blank mold shown in fig. 4, a blank mold for producing a glass cream bottle, is used, a blank mold concave 81 for forming the positioning pin 4 is provided at a position for forming the bottle mouth 1, and the blank mold concave 81 is located at a mold clamping surface. As the prior art, the primary mold comprises two neck molds 83 and two primary mold half-molds 82, in the molding process, the two primary mold half-molds 82 clamp the two neck molds 83 in the middle, the neck molds 83 are used for molding the bottle mouth 1 of the product, and the two primary mold half-molds 82 are used for molding the bottle body of the primary blank. It should be noted that the "body of the preform" is not the body 2 of the product, the "body of the preform" is smaller than the body 2 of the product, and the "body of the preform" needs to be blown up and cooled in the mold to become the body 2 of the product; the bottle mouth 1 is finally formed in a primary mold and is cooled and hardened, the bottle mouth 1 is not deformed in the molding process, two neck molds 83 are generally used for clamping the bottle mouth 1 in the production process, and the primary blank is turned into the molding process.

The forming die matched with the bottle mouth 1 is shown in fig. 5, and the forming die for producing the glass cream bottle comprises two forming die halves 9, wherein the top of each forming die half 9 is provided with a forming concave pit 91 used for being matched with the positioning nail 4, and the forming concave pits 91 are positioned at the joint surfaces. Some molding dies comprise a bottom die, the bottom die is clamped between two molding die halves 9 during molding, and the bottom surface of the produced bottle has no joint line; some of the molds do not have a bottom mold, and the produced bottles have a seaming line. The presence or absence of the counter-die is not relevant for the improvement of the utility model in the vicinity of the bottle mouth 1 and will not be discussed in detail.

The utility model mainly relies on three principles to realize the beneficial effects: firstly, concave-convex matching positioning. Secondly, the bottle mouth 1 is cooled and hardened after the primary mold forming. And thirdly, the product inevitably has a joint line.

The positioning nail 4 is formed at the bottle mouth 1 of the cream bottle blank manufactured by the primary die, the forming die is provided with a forming die pit 91, when the primary blank is turned to the forming die from the primary die, the positioning nail 4 of the cream bottle blank falls into the forming die pit 91, the cream bottle blank cannot rotate, and the finally formed cream bottle cannot have the defects of overlarge joint line, double joint lines (two lines on each side) or staggered joints and the like. In addition, the positioning pin 4 is positioned on the joint line 3, and can be cooled and hardened more quickly in the primary mold; on the other hand, the commissure lines 3 make the tack 4 more convex and pointed, and easier to locate in the mold.

The positioning nails 4 are formed at the joint surfaces to be more convex and sharper because the molten glass inevitably seeps into the gaps in the mold, and the joint lines affect the appearance of the bottle body 2, but are more favorable for positioning the positioning nails 4. Preferably, one cream bottle has two positioning pegs 4, one on each side.

For easier positioning, the bottom of the positioning nail 4 is an arc surface, the bottom of the molding pit 91 is also an arc surface, and after the primary blank is turned over from the primary mold to the molding, when the mouth mold 83 releases the bottle mouth 1, even if the primary blank rotates for a certain time due to vibration, the arc surface can guide the positioning nail 4 to align with the molding pit 91.

Specifically, the (radial) projection amplitude of the positioning nail 4 is 1% -2% of the outer diameter of the bottle mouth 1. The horizontal width of the positioning nail 4 is 5% -6% of the outer diameter of the bottle mouth 1, and the vertical height of the positioning nail 4 is 5% -6% of the outer diameter of the bottle mouth 1. This dimension can exert reliable positioning performance and is not apparent in product appearance.

Some products have a neck, the mouth 1 of which is divided into an upper part and a lower part, the upper part being a cap engaging part 11 provided with an external thread 111 and the lower part being a non-threaded neck part 12. The following three positions of the positioning pin 4 exist.

Firstly, referring to fig. 2, the positioning pin 4 is disposed on the bottle cap combining portion 11 and located below the external thread 111, the protruding range of the positioning pin 4 is smaller than that of the external thread 111, and the protruding range of the positioning pin 4 is 1% -2% of the outer diameter of the bottle cap combining portion 11. This scheme can make location nail 4 and bottle lid have the cooperation relation, for example, set up on the bottle lid with location nail 4 complex screens, can send "papda" sound suggestion when screwing up the bottle lid and screw up. Therefore, the positioning nail 4 can prevent the primary blank from rotating in production and can be tightly matched with the bottle cap when the product is used.

Secondly, referring to fig. 3, the outer diameter of the bottle neck 12 is larger than that of the bottle cap joint 11, the positioning pin 4 is arranged on the bottle neck 12, and the protruding range of the positioning pin 4 is 1% -2% of the outer diameter of the bottle neck 12. The outer diameter of the neck 12 is larger than the outer diameter of the cap engaging portion 11 to abut against the cap, which is also a way to indicate that the cap is screwed on, but in this case the positioning pin 4 is made to be more obvious in appearance of the product.

Thirdly, referring to fig. 1, the outer diameter of the bottle neck 12 is smaller than the outer diameter of the bottle cap joint 11, the positioning pin 4 is disposed at the joint between the bottle cap joint 11 and the bottle neck 12, the protrusion range of the positioning pin 4 is 1% -2% of the outer diameter of the bottle neck 12 within the vertical projection range of the bottle cap joint 11. The position of the preliminary mold recess 81 in the preliminary mold shown in fig. 4 and the position of the molding recess 91 in the molding mold shown in fig. 5 are made around the third solution, which is advantageous in that the positioning pins 4 can be hidden well in appearance, giving the product the appearance of a conventional cream bottle.

In the first and second versions, the initial mold recesses 81 are provided in the die 83; in a third version, the primary mold recesses 81 are provided in the primary mold halves 82.
