Beneficial effect of the present invention: the opening part of the box body of plastic uptake processes of the present invention is formed with the box mouth rim charge of ring-type, utilize PP material by the edge formation one circle injection moulding circle of Shooting Technique along box mouth rim charge, the intensity of box body opening part (box mouth rim charge) is strengthened by injection moulding circle, when making box mouth place and the lid interference fit of box body, box mouth is not yielding, reach better sealing effectiveness, and packing box of the present invention can reuse, compared to traditional film seal, more hygienic environment-protecting; In addition, the end of lid of the present invention is formed with back-off position, and during interference fit, back-off position can fasten the bottom of injection moulding circle, reaches the effect of sealing further; Further, the inwall of lid of the present invention is provided with soft seal ring, the upper surface of injection moulding circle is formed with a circle baffle ring, with upwardly seal ring when sealing, can play multi-sealed effect; Also have, box body of the present invention is formed by plastic uptake processes by more than three layers or three layers co-extrusion material, not only can the thickness of effective control capsule body, can also effectively prevent oxygen and vapor permeation from entering in box body, avoid the food septic yeast in packing box, be particularly suitable for the food that all kinds of sauce, jam, flavoring, biscuit and jelly etc. need long-term storage.
Accompanying drawing explanation
Fig. 1 is the cutaway view of sealing packaging box of the present invention;
Fig. 2 is the structural representation of the work material of box body of the present invention.
Detailed description of the invention
Be further elaborated the present invention below in conjunction with accompanying drawing, wherein, direction of the present invention take Fig. 1 as standard.
As shown in Figure 1, sealing packaging box of the present invention comprises lid 1, box body 2 and injection moulding circle 3, lid 1 is processed by Shooting Technique by LDPE material, the end of lid 1 is formed with back-off position 11, box body 2 is formed by plastic uptake processes by more than three layers or three layers co-extrusion material, the outside bending of open end of box body 2, and extend to form the box mouth rim charge 21 of ring-type, box mouth rim charge 21 is the table top of a loop of opening part around box body 2, the outer end of box mouth rim charge 21 is provided with the injection moulding circle 3 of a loop, injection moulding circle 3 is formed in the opening part (outer end) of box mouth rim charge 21 by Shooting Technique by PP material, thus it is integrated with box body 2 to reach injection moulding circle 3, in order to ensure the perfect adaptation of Shooting Technique and plastic uptake technique, one section of outer wall along box mouth rim charge of injection moulding circle 3 of the present invention is to downward-extension, cover the lateral wall of part box body and form labeling plate face, silk-screen the latter labeling can be carried out in position, labeling plate face, interference fit is passed through between lid 1 madial wall and injection moulding circle 3 lateral wall, the back-off position 11 of lid 1 fastens the bottom of injection moulding circle 3, to reach sealing effectiveness.
Further, in order to ensure the leak tightness between injection moulding circle 3 and lid 1, the present invention can also arrange at the inwall bending part of lid 1 seal ring 4 that a soft material makes, a circle baffle ring 31 is formed at the upper surface of injection moulding circle 3, baffle ring 31 rounds along the opening of box body 2, and when lid 1 covers box body 2, baffle ring 31 is seal ring 4 upwardly, multi-sealed effect can be reached, to reach better fresh-keeping object.
Wherein, as shown in Figure 2, box body 2 of the present invention is paid the utmost attention to and is adopted five-layer co-squeezing material to make, and five-layer co-squeezing material comprises a barrier layer 22, two bonding coats 23 and two substrate layers 24, barrier layer 22 is positioned at midway location, is generally processed by ethene or ethenol copolymer; Two bonding coats 23 cover two surfaces up and down of barrier layer 22 respectively, and play adhesive effect, bonding coat 23 is generally processed by maleic anhydride grafted resin; Two substrate layers 24 cover two bonding coat 23 outside faces respectively, and substrate layer 24 is generally formed by one or several materials processings in HIPS, SBS, GPPS, PP or PE, and barrier layer 22, bonding coat 23 and substrate layer 24 are sheet material.In sum, box body 2 is five layers of supply plastic uptake sheet material, can blocking oxygen and other gas preferably, accomplish to protect fragrant fresh-keeping function for a long time, to reach the non-perishable object of commodity, and be generally injection molded into the product of flask body, cannot make multi-layer co-extruded sidewall, food is easily permeated the oxygen of entering and vapor corrosion goes bad, and realizes although multi-layer co-extruded technique can be blown on machine at note, but it is thicker to note the box body wall thickness of producing by boasting, and cost increases greatly.
The concrete stroke of injection moulding circle 3 is: first utilize five-layer co-squeezing extruder to extrude and make box body 2 five-layer co-squeezing material used; Then, utilize blistering machine by above-mentioned for the five-layer co-squeezing forming materials profile being formed with the box body 2 of box mouth rim charge 21; Then utilize manipulator to be pressed from both sides out by box body 2, move and be put on injection mould dynamic mould core, the outer end mold-closing injection one along box mouth rim charge 21 encloses the injection moulding circle 3 that hard PP material is made, thus realizes the integration product of a kind of injection moulding and plastic uptake two kinds of techniques combinations.
The foregoing is only better embodiment of the present invention, the present invention is not limited to above-mentioned embodiment, the structural modification that local is small may be there is in implementation process, if do not depart from the spirit and scope of the present invention to various change of the present invention or modification, and belonging within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these change and modification.
