A kind of stackable drinking-water bottle and manufacturing approach thereof
Technical field
The present invention relates to a kind of plastic bottle, especially relate to the plastic bottle that a kind of big Sheng is drunk water.
Background technology
The big drinking-water bottle of existing plastics is various in style, and all being has a bottleneck, bottleneck, body, the bottle end.Bottleneck has the long weak point that has, no matter length goes up occupation space but the height of this bottleneck has directly increased transportation; In when bottle transportation drinking-water, each layer occupation space, account for more than 25% than the own vol of drinking-water bottle more; In addition, the drinking-water bottle is gone up label paper and is sticked, and loses easily.
Summary of the invention
The present invention seeks in order to overcome the deficiency of prior art, a kind of stackable drinking-water bottle and manufacturing approach thereof be provided,
The technical scheme that the present invention taked is: the raw material that a kind of stackable drinking-water bottle adopts is PC (polycarbonate), is divided into bottleneck, bottleneck, shoulder, bottle, the bottle end, and described bottle is to process the identical hexahedron of face width; Shoulder is provided with reinforcing pad, and the middle epimere of bottle is provided with reinforced rib, and the bottle end is provided with reinforcing pad; Above reinforcing pad (muscle) is higher than bottle, and surface design has the piebald of gash, is used to protect bottle; The scar generation that sassafras causes is scraped in release when transportation, described bottleneck and shoulder joint are stress points, are provided with special reinforcing pad; It is characterized in that: six faces of bottle are arranged between the epimere reinforced rib in shoulder reinforcing pad and bottle, and these six faces are provided with to be inserted, and it is smooth smooth with the bottle shell wall to insert; Merge one, the described bottle end, be designed to fall in significantly, and recessed shaped design is the shape of bottleneck and shoulder; Its size is able to harmoniously similar bottleneck, the shoulder of drinking water bottle of another is inserted in, and is tightly not loose.
Manufacturing process of the present invention and manufacturing approach are: annotate the stretch blow one step processing.
Mould-manufacturing: because body is than conventional short, the recessed amplitude in bottom is big, so pipe embryo mould, injection moulding cores are wanted strict and pressed drawing construction, outer casing mold was used a pair of slide block originally; A pair of slide block is used in designed enclosures mould side now, increases independently bed die, and on a pair of slide block of described outer casing mold side, setting is inserted; The position is set between the epimere reinforced rib, has six faces in shoulder reinforcing pad and bottle, each face edge lastblock; Totally six, insert that it is smooth smooth to be connected with slide block, merge one.
Production procedure: first injection moulding bottle embryo, because the recessed degree of depth in the bottle end is especially big, in the heating period of bottle embryo; The design heating-up temperature increases by 5 ℃ than general technology, and playing increases the flowing power effect, completion blow draw program after; Earlier with the bed die disengagement of leaving behind; Again slide block is drawn back, eject the drinking-water bottle, finish one along ring.
The invention has the beneficial effects as follows: when drinking-water bottle stacked up and down, the space of compared with prior art saving was about 25%, thereby has practiced thrift traffic cost, has practiced thrift the consumption of the transportation energy; Because described inserting can be carved literal and figure for maker's casting, just on bottle, not only outward appearance is beautiful attractive in appearance for this casting literal at quarter and figure, and can effectively prevent the product personation.
Description of drawings
Fig. 1 is six front elevations of transparent drinking-water bottle one side wherein of specific embodiment of the present invention
Fig. 2 is the recessed scheme drawing in drinking-water bottle bottom of specific embodiment of the present invention.
The specific embodiment
Be elaborated below in conjunction with Fig. 1, Fig. 2: the raw material that a kind of stackable drinking-water bottle adopts is PC (polycarbonate), is divided into bottleneck 1, bottleneck 2, shoulder 3, bottle 4, the bottle end 5, and described bottle 4 is to process the identical hexahedron of face width; Shoulder 3 is provided with reinforcing pad, and the middle epimere of bottle has reinforced rib 6, and the bottle end 5 is provided with reinforcing pad; Above reinforcing pad (muscle) is higher than bottle 4, and surface design has the piebald of gash, and the scar generation that sassafras causes is scraped in 4 releases of protection bottle when transportation; Described bottleneck 2 is stress points with shoulder 3 joints, is provided with special reinforcing pad 8, and six faces of bottle 4 are arranged between the epimere reinforced rib 6 in shoulder 3 reinforcing pads and bottle; These six faces are provided with inserts 7, and it is 7 smooth smooth with bottle 4 shell walls to insert, and merges one; The described bottle end 5, be designed to fall in significantly; Recessed shaped design is the shape of bottleneck 2 and shoulder 3, and its shape size is able to harmoniously similar bottleneck 2, the shoulder 3 of drinking water bottle of another is inserted in, and is tightly not loose.
Manufacturing process of the present invention and manufacturing approach are: annotate the stretch blow one step processing.
Mould-manufacturing: because body is than conventional short, the recessed amplitude in bottom is big, so pipe embryo mould, injection moulding cores are wanted the strict drawing construction of pressing; Outer casing mold was used a pair of slide block originally, and design is now adopted a pair of slide block in the side, increases independently bed die; Six faces of bottle are arranged between the epimere reinforced rib in shoulder reinforcing pad and bottle, and on a pair of slide block of shell die side face, the position of corresponding these six faces is provided with and inserts; Each face edge lastblock; Totally six, insert that it is smooth smooth to be connected with the slide block shell wall, merge one.
Production procedure: first injection moulding bottle embryo, because the recessed degree of depth in the bottle end is especially big, in the heating period of bottle embryo; The design heating-up temperature will increase by 5 ℃ than general technology, and playing increases the flowing power effect, completion blow draw program after; Earlier with the bed die disengagement of leaving behind; Again slide block is drawn back, eject the drinking-water bottle, finish one along ring.
