Abstract
The plastic soft tubular container is manufactured by using polyethylene terephthalate (PET), polyethylene naphthalene-2,3-dicarboxylate (PEN), or polypropylene (PP) as material and through accelerated elongation and blowing into container with homogeneous thickness, tail cutting by laser, high-speed water cutter or supersonic cutter, filling and tail fusing. The complete single layer soft tubular container is light, simple in manufacture and practical, and has the features of high oxygen separation, easy recovery, etc.
Description
The present invention relates to a kind of manufacture method of plastic hose container, the monolayer plastic flexible pipe manufacture method that refers in particular to a kind of in light weight, high oxygen barrier and can reclaim easily.
Conventional flexible pipe container glue tank as being applied to, Cleansing Foam etc., all adopt PE (polyethylene) material, it is to make institute's pipe in the extrusion molding mode, cut to required length again, and form the locking screw thread of bottle cap in flexible pipe top desire, then must go out bottle cap to the upper end with another Mold Making again, it and flexible pipe adopt the mode of combination processing to be combined into one with the moulding hot melt, it is complicated and loaded down with trivial details that procedure of processing promptly seems, polyethylene (PE) material of while because of selecting for use, flexible pipe can't be made into the transparency and increase its purposes, and it is not enough to have an oxygen-barrier property, cause the shortcoming of content oxidation deterioration easily.
The objective of the invention is to propose a kind ofly monolayer plastic is extended stretch blow with high power speed become the uniform container of thickness, excise the container afterbody in modes such as laser, high speed water cutter, super sonics again, fill to inject PET, PEN that the step of content, afterbody fusion forms or the manufacture method of PP plastic hose container then, it not only simplifies procedure of processing, and increased the physical property of material, and make flexible pipe make transparence, thereby solved the existing in prior technology problem.
The technical solution adopted in the present invention is: it is the bottle embryo that individual layer is made into required size; Blown to draw with higher extension ratio with the stretch blow machine again and stretched, make a bottle embryogenesis thickness of pipe that the bottom tube-like container be arranged uniformly; To there be the bottom of bottom tube-like container to be excised again in modes such as laser, high speed water cutter, super sonics; Fill then and inject content; With the bottom end opening fusion, promptly finish a complete individual layer flexible pipe finished product again.
The said plastics of the present invention be polyethylene to too sour fat PET, or polyethylene 2,6 acid esters PET how, also polypropylene PP.Said extension ratio is 3.2 to 3.4 times.Said bottle embryogenesis thickness of pipe is at 0.1～0.5mm (millimeter).Said have a bottom tube-like container, and it can be added a cover or with aluminum sealing lid at bottleneck.
Characteristics of the present invention are: it can simplify procedure of processing, and increases the physical property of material, and can make flexible pipe make transparence, increases its field of application.
Fig. 1 makes diagram of circuit for the present invention.
Fig. 2 (A)～(E) is a making scheme drawing of the present invention.
Further specify preferred embodiment of the present invention in conjunction with above-mentioned accompanying drawing now, as shown in Figure 1, and, then can further understand method for making of the present invention in conjunction with the step shown in Fig. 2 (A)～(E):
In the present embodiment, plastic hose material of the present invention can adopt a kind of polyethylene to too sour fat (PET, polyethylene terephthalate) or polyethylene 2,6 sour fat (PEN how, polyethylene2,6naphthalate) or polypropylene (Polypropylene) resin.For making mouth cylindrical part that precise shape and size can be arranged, the mode of at first utilizing ejection formation is with the single-layer PET resin, PEN resin or PP resin are made into the bottle embryo 10 of required size, shown in Fig. 2 (A), the bottle mouth position of this bottle embryo 10 is the one-body molded locking screw thread 11 that has, then with the stretch blow machine with higher extension ratio, 3.2～3.4 times, in addition stretch blow is extended, make bottle embryo 10 form thickness at 0.1 to 0.5mm (millimeter), thickness of pipe has bottom tube-like container 20 uniformly, shown in Fig. 2 (B), can form a flexible pipe half-blank and preserved this moment, and during preservation, entered in the bottom tube-like container 20 for preventing foreign matter, can add lid 12 or with aluminum sealing lid at bottleneck.
Shown in Fig. 2 (C), when filling content (as glue or Cleansing Foam etc.), to there be the bottom of bottom tube-like tolerant 20 to be excised earlier in modes such as laser, high speed water cutter, super sonics, fill then and inject shown in Fig. 2 (D), again bottom end opening is fused, promptly finish an individual layer flexible pipe container finished product, shown in Fig. 2 (E).
Method for making of the present invention, can will summarize following step:
A, the accurate bottle embryo that forms;
B, with the stretch blow machine according to extension ratio with the stretch blow of bottle embryo, a shape container at the bottom of being formed with tin;
C, incision have bottom tube-like container bottom;
D, injection content;
E, bottom end opening are fused, and finish finished product;
As mentioned above, PET provided by the present invention, PEN and PP flexible pipe container method for making are extended single-layer PET resin PEN resin or PP resin and to be blow molded into the uniform container of thickness with high magnification; Can significantly strengthen the oxygen-barrier property of container, compare with the modular multilevel formula flexible pipe container of routine, not only has in light weight, the simple advantage of work programme, and can be made into flexible pipe container transparent and promote its occupation mode, but the disclosed idea of mat proposes effective solution at the defective of conventional flexible pipe processing mode and the effect of failing to reach really; Further, increase the unexistent function of conventional approach, have the value that novelty, creativeness, practicality and industry are utilized.
Below the present invention has been done a detailed description, but above said, only be preferred embodiment of the present invention, can not limit the scope of enforcement of the present invention certainly.Be all variations of doing according to claim scope of the present invention and modification etc., all should still belong to scope of patent protection of the present invention.
