CN2237601Y - Integrated beverage plastic bottle - Google Patents

Abstract

The utility model relates to a beverage bottle integrally formed by moulded plastic material, which comprises a bottle body and a bottle jack, wherein, the lower part of the bottle jack and an opening reduction part at the upper part of the bottle body are connected into a bottleneck, the inner wall from the bottle jack to the bottle neck presents a smooth round tube shape, the outer wall at the connection position between the bottle neck and the bottle jack is provided with a solid bulged holding ring, and the outer wall from the solid bulged holding ring to the opening of the bottle jack is provided with solid screw threads. Because of the smooth inner wall of the bottle jack, liquid remained in the groove of the inner wall of the bottle jack is avoided. The thickness of the bottle neck and the bottle jack is increased, so that a bottle cap can be closely combined with less air leakage and deformation. Additionally, the beverage bottle can be formed integrally by using regenerated PP material.

Description

Integrated beverage plastic cement bottle

The utility model relates to a kind of with the integrated beverage bottle of molded plastic material.

Make the plastic cement bottle with plastic material, mostly adopt the bottle blowing method of air blowing type, along with the difference of the liquid of adorning, beverage in the bottle, and the demand of using different plastic materials is arranged, as PE, PVC, PET, PP ... etc. multiple plastic material.After moulding, light weight, the good characteristic of diaphaneity are arranged, therefore adopted by the drink manufacturing merchant.But this kind PET PET bottle is all because the use of can't regenerating after using causes great destruction and influence to environmental ecology.Therefore, take the measure of reclaiming, a kind of plastic cement bottle of PVC material then to use, when being the liquid of higher temperature when filling, then need use the PP material of beverage level at filling cryogenic liquid beverage.

When generally making bottle with bottle blowing method, because plastic material is earlier dissolved, blowing moulding in the mould that reinjects.Because gas blow pipe places the bottleneck upper end of mould, referring to Fig. 1, its bottleneck (1) inwall all can form indenture (14) along with the protrusion screw thread (11) of bottleneck outer wall, especially be used for bulge loop (12) position of clamping at bottleneck than the lower end, its inwall all can form a profound chase (15), this be plastic material by the natural phenomenon of blowing moulding, all can't solve the bottleneck problem of an air blowing type forming process of this kind in decades.

The bottleneck inwall has the plastic cement bottle of chase, as desires to be used for loading beverage, just bottle must be washed one by one, and be sterilized.But, after the bottle sterilization, the bottle in moisture content, when sterilised liq will be poured out, will locate too dark residual liquid because of the chase in the bottleneck (15), promptly use high pressure blow-gas also to be difficult for full scale clearance, in case the QC personnel not to be noted, promptly begin the filling beverage, after liquid entered in the bottle, residue promptly can advance bottle interior beverage blends with filling, and this situation will cause beverage to go bad or breed bacteria.Present various tea beverage or non-sparkling water maker all quite have a headache to this kind problem, and the beverage quantity of not passed through by product examine is a lot.Though the technology of the legal system of blowing for many years bottle constantly promotes, manufacturing speed has also obtained enhancement, and the significant problem that has only plastic cement bottle bottleneck can't break through always, also allows the beverage dealer cause greatest loss and puzzlement.

The purpose of this utility model is to provide a kind of bottleneck inwall smooth smooth, not yielding or disappointing, integrated beverage plastic cement bottle.

The utility model comprises bottle and bottleneck, the upper opening reducing diameter part of bottleneck bottom and bottle is linked to be bottleneck, bottleneck to bottleneck inwall is smooth round tubular, and bottleneck and bottleneck junction outer wall are established solid clamping bulge loop, and solid clamping bulge loop to bottleneck opening part outer wall is established solid screw thread.

Compare with the plastic cement bottle with existing beverage, the utility model has smooth smooth bottleneck inwall, has avoided residual liquid in bottleneck inwall chase, in order to avoid cause beverage rotten.Simultaneously solid clamping bulge loop and the solid screw thread of bottleneck have increased the thickness of bottleneck and bottle mouth position, when tightening aluminium lid after bottled, in conjunction with closely, are difficult for losing heart and being out of shape, and improve its leak tightness.And can use the PP raw material of regeneration, and reduce environmental pollution, lower manufacturing cost.

Fig. 1 is existing beverage plastic cement bottle bottleneck cutaway view.

Fig. 2 is the utility model bottleneck cutaway view.

Fig. 3 is the utility model manufacturing process scheme drawing.

Used gas blow pipe when Fig. 4 makes for the utility model.

Embodiment: as shown in Figure 2, the utility model comprises bottleneck (2) and bottle (3), the upper opening reducing diameter part (31) of bottleneck bottom and bottle is linked to be bottleneck, bottleneck to bottleneck inwall (23) is smooth round tubular, bottleneck and bottleneck junction outer wall are established solid clamping bulge loop (22), and solid clamping bulge loop to bottleneck opening part outer wall is established solid screw thread (21).

In order to implement such scheme, referring to Fig. 3,4, when plastic material dissolves, push out pipe shape soft plastic pipe downwards by outpouring mouth, move to again in the two-piece type bottle mould (5), then gas blow pipe (4) is stretched in bottle mould, the upper end of gas blow pipe (4) have joint (41) can for the connector engages of air duct, with the cooresponding air blowing body of bottleneck bore (42) the central authorities air blowing mesopore (43) for running through, and length that should the air blowing body is about plastic cement bottle bottleneck top to the position that is connected with bottle and is as the criterion.In addition, the body (42) of gas blow pipe (4) from top to bottom is cone.When gas blow pipe (4) when bottle mould central authorities press down, just the plastic material at bottle mould top can be pressed down, form thicker mouth cylindrical part, simultaneously pressurization is blown immediately, is the plastic cement bottle with the plastic material that dissolves according to blowing moulding of shape of two-piece type bottle mould.When air blowing is finished, make the suitable angle of gas blow pipe (4) rotation one thereupon after, as shown in Figure 3, can the slick and sly outer wall of this gas blow pipe of mat (4), the still unhardened raw material of pushing bottleneck inwall makes inwall be the surface of a slyness in rotation.Partly tube wall is very thick though be used for bulge loop (22) that gripping bottle uses, is subjected at plastic material also just can not cause chase under the situation of gas blow pipe body (42) outer wall pushing.

And existing air blast, all just gas blow pipe is placed on the bottleneck port to blow, and, the caliber of its gas blow pipe is also less, blow in the position of bottleneck upper end that places bottle mould, natural when blowing moulding, the screw thread of bottleneck and bulge loop place, its inwall will form indenture and chase naturally because of the bottleneck shape pressurized of mould.

Claims (1)

1, integrated beverage plastic cement bottle, comprise bottle and bottleneck, the upper opening reducing diameter part of bottleneck bottom and bottle is linked to be bottleneck, bottleneck and bottleneck junction outer wall are established the clamping bulge loop, and clamping bulge loop to bottleneck opening part outer wall is established screw thread, it is characterized in that bottleneck to bottleneck inwall is smooth round tubular, bottleneck and bottleneck junction outer wall are established solid clamping bulge loop, and solid clamping bulge loop to bottleneck opening part outer wall is established solid screw thread.
