Description
Technical field
The present invention relates to the injection molding forming method of container, container and the die injection moulding of container.In more detail, container of the present invention is wide-mouth, has back-off (Japanese: ア ン ダ ー カ ッ ト) in the inner side of container body.Injection molding forming method of the present invention and die injection moulding are for the manufacture of such container.
Background technology
Past, as for filling container for example butyraceous cosmetic, used for cosmetic, the container of known wide-mouth.The container of wide-mouth, is mainly made up of container body, gasket seal and cap.
Cap is installed in the neck of container body.The also known roughly the same container of external diameter that makes container body and cap.The container body of such container, is provided with difference at the external diameter of cylinder portion and neck.As the cylinder portion at container body and the external diameter of neck arrange difference,, at the outer peripheral face of container body, form the part (shoulder) that external diameter changes from neck to cylinder portion.
In the container that is formed with shoulder, exist the inner peripheral surface of shoulder to have the type of back-off and there is no the type of back-off.The inner peripheral surface of shoulder does not have the type of back-off, although cylinder portion external diameter compared with neck is large, internal diameter is changeless from cylinder portion to neck.This type, because there is no back-off, so, by the moulding of injection mo(u)lding means in the situation that, easily carry out the withdrawing pattern of mould.But, thickening compared with the wall thickness of cylinder portion of container body and the wall thickness of neck, the use quantitative change of resin is many.In addition, because be heavy wall, so resin is difficult to cooling curing when injection mo(u)lding, injection mo(u)lding is time-consuming.Therefore, exist manufacturing cost high and be difficult to provide with low cost the problem of container.
On the other hand, the inner peripheral surface of shoulder has the type of back-off, and the degree of depth of back-off is larger, can the wall thickness of the cylinder portion of container body be formed thinlyyer, can reduce the use amount of resin.In addition, as wall thickness, the easy cooling curing of resin when injection mo(u)lding, can shorten time of injection mo(u)lding.Therefore, manufacturing cost is suppressed, provides container to become possibility with low cost.But, because there is back-off, so, become difficulty at the withdrawing pattern that carries out the situation bed die of moulding by injection mo(u)lding.As the technology that is had container back-off, wide-mouth by the manufacture of injection mo(u)lding means, known for example patent documentation 1,2.
In the injection molding technology of patent documentation 1,2, the withdrawing pattern of mould is undertaken by so-called pressure withdrawing pattern.Specifically, in the die cavity to die injection moulding, inject after resin, before resin cooling curing, carried out die sinking, carried out withdrawing pattern from larger mould compared with the peristome drawing of neck of the container body as formed body and the internal diameter of peristome., there is following such problem in the withdrawing pattern of forcing withdrawing pattern to carry out by this.
First, force withdrawing pattern because be to make peristome be out of shape to carry out the withdrawing pattern of mould before the complete cooling curing of resin, so, be difficult to the formed products of the shape that obtains the forming surface of verily having reproduced mould.Particularly, because the dimensional accuracy step-down of the peristome of container body, so the air-tightness under the state that cap has been installed is low.For example, for the container of the filling of cosmetic, cap being arranged under the state on container body, require high air-tightness.This be in the case of with filling the state of cosmetic also can prevent the content being caused by the expansion of content, internal gas, the leakage of internal gas being placed under the environment of indoor high temperature.But, as low in the dimensional accuracy of the peristome of container body, even if adopt gasket seal, also produce deviation for each product in air-tightness.Therefore,, as by forcing withdrawing pattern to carry out the withdrawing pattern of container body, be difficult to meet the air-tightness being required.
In addition, force withdrawing pattern, as dark step-like in back-off is made, the withdrawing pattern of mould becomes difficulty, so, need back-off by shallow and level and smooth Surface forming, make withdrawing pattern easy.Because the restriction of the degree of depth of back-off, shape, can not form fully thinly by the wall thickness of the cylinder portion of container body sometimes, form unnecessary wall thickness part at the inner peripheral surface of shoulder.Therefore, can not cut down the use amount of resin, be difficult to manufacture with low cost.
And, force withdrawing pattern, because be to make peristome distortion before the complete cooling curing of resin, carry out the withdrawing pattern of mould, so, must manage according to precision target these multiple condition of molding on opportunity of temperature, the withdrawing pattern of resin.As departed from condition of molding, there is defective work.But, because be difficult to manage multiple conditions of molding according to precision target, how do disqualification rate and all uprise, so, be difficult to manufacture with low cost.
That is, there is the technology of container back-off, wide-mouth as the inner side that is molded over container body by injection mo(u)lding, the past, known to forcing withdrawing pattern to carry out the technology of withdrawing pattern, but in pressure withdrawing pattern, be difficult to meet the air-tightness of container requirement.In addition, in pressure withdrawing pattern, be also difficult to low cost fabrication container.
In addition, there is the technology of container back-off, wide-mouth as injection mo(u)lding, also the injection molding technology of the so-called telescopic core of known use.Telescopic core, is by centrepin is extracted, the halved core mould of undergauge to the inside having cut.As use telescopic core, can in the time of withdrawing pattern, make mould undergauge, so, do not force withdrawing pattern just can carry out withdrawing pattern to mould.But, as used telescopic core, there is the problem that forms parting line on container body in the position corresponding with the divisional plane of telescopic core.As the peristome of the neck at container body, particularly form parting line in the end of peristome, because parting line small concavo-convex, the contact of gasket seal, cap becomes inhomogeneous, air-tightness declines, exist content, internal gas from contact step-down the problem that spills of position.
