- The synthetic resin container, which is found in the commercial space of the commercial mat, mostly uses a so-called general-purpose polyethylene such as a stupid ethylene homopolymer having excellent tensile strength, heat resistance, light resistance, properties, and surface gloss. Resin (GPPS: General purpose Polystyrene), or the internal friction of polystyrene-based resin containers with internal rubber and SBR, BR and other rubbers to improve their brittleness. Laminated body. This recorded = rare (HIPS: High Impaet ρ〇1 purchase). For the cover material to be attached to such a mouth portion to be sealed,

The mouth contact portion of the container opening 89490-970901.doc 1308896 will be at the end of the lid, and it will be maintained from the 1 1 < under the broken cover. 3. It can prevent the container from being stained near the opening of the container. Water is not only a good guard but also very good. It has always been widely used. However, in recent years, there have been many incidents in the processing of food containers, and the Queen’s countermeasures have become a problem. However, because of the use of metal detectors, such as the use of such aluminum cover, Therefore, there is a problem that it is impossible to check the metal nails such as the nails, the nails, the fragments of the molded products, the bolts and the linings, the metal wires, and the springs. Further, the container having such an inscription cover must be separated from the original cover and the container body of the polystyrene synthetic resin, which has the disadvantage of poor recovery. : The proposal points out that this traditional inscription is replaced by a cover made entirely of plastic; Such as 'the system is revealed to contain high density polyethylene and polypropylene. a central layer of the object' and a coextruded film material having a coating layer composed of high density polyethylene on both sides of the center layer

On the both sides of the base material of the "-" four-layer substrate, 'the surface of the base material having heat resistance and s soil material', the laminated material provided with the sealant layer is punched into a specific shape of the cover material (Japan (4) W No. L The plastic cover will be followed by the end of the container, so that the outer peripheral portion of the adhesive surface is not folded back to form a flat shape that continues to extend. When directly filling the container from the container to the container, there is a problem of hygiene. When the container is made of polystyrene resin such as GPPS or s, the body of the τ 囚 盍 谷 谷 谷 谷 谷 谷 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体 本体The slab of the slab is between the pair of convex and f-shaped concave molds (mother molds), and the slab is used to form the slab into the concave mold by the convex mold, and the dicing material plate made of Ig is plastically deformed by using ndt cutting And the shape and shape of 89490-970901.doc 1308896 (4) is carried out by the cold forming method of the stomach stamping forming method, and the formed aluminum cover has the shape retaining property for maintaining the deformation, and then the cover is applied when Should (4), due to the change in the shape of the molecule, it will be subject to: Pressing into the liters below the temperature of the glass transition point: when the 'has a strong tendency to restore the shape. Therefore, when the forming process is completed, that is, when the mold is released, the elastic recovery will occur and the forming precision will be lowered, and the time-lapse will occur later. The change of 'the cold section below the glass transfer point' is not able to obtain a plastic cover that can faithfully conform to the shape of the mold to maintain the shape of the end material (four). Also, in order to form the shape of the cold form Some people have tried to use thicker plates or harder materials ''', but not only can not obtain a cover with sufficient shape retention, and even the problem of deterioration of openness. (4) The following proposal is made. The thermoplastic resin (4) and the non-extended low-temperature adhesion (four) product (4) are subjected to low-temperature heating in such a manner that the thermoplastic resin is located inside: pre-forming, and the preform is placed on the flange of the capacitor 11 By using ., , and shrinking, it is a method of sealing the film in accordance with the Japanese Patent Publication No. 157603 (Japanese special public, ..., this method uses heating to make the resin produce 2 f raw only, and must be g and die 1_ η »* , /, can be achieved by the heating and cooling mechanism of the tree, so the problem of large-scale, complicated and low-speed filling of the cover forming device and the capping device: 2: The device is generally filled with a beverage in the container. If the hair is on the line / the step ' however, the formation and filling step is the result of the problem: the problem is to use the resin to heat the formation of the above method, and the right side of the six + small take time 盍 积 accumulated in the heating zone The resin film for forming must be completely obscured by 89490-97090i.doc 1308896. If it is to be avoided, it is necessary to separately set the means for retracting the heating device. Also, when the device is driven, the temperature is required to reach a certain temperature. For a while, there is a problem that the material of the container material and the time consumption cannot be avoided. Others have the method shown below, that is, heating the front end of the Jianshan-shaped jig to a temperature above the glass transition point of the resin film and below the softening point, and using the heated Jianshan-shaped jig to press and push The plastic deformation method of the resin film is carried out by the operation (JP-A-2001-76581), or the pre-formed sheet rubber or resin material formed by continuous extrusion molding is heated and simultaneously subjected to stress to produce plastic deformation. Plastics deformation processing products (JP-A-2000-135744), but both methods require a permanent heat step, so the above problem cannot be solved. 有人 Some people have proposed the following proposal, that is, having a strip shape The metal plate forms a step of forming the insert; the insert is treated as a core material, and is coated by co-extrusion of rubber or resin, thereby forming a step of forming the coated strip, and plastically deforming the coated strip. A method for producing a lining strip of a plastic deformation step which forms a lining (Japanese Patent Laid-Open No. Hei 5-2379G4), but the invention uses a metal body as a heart material The plastic deformation of the resin is not related to the processed product obtained by subjecting the metal-free pure resin sheet to cold forming.

After forming, as the punch 5 retreats back to its original position, the piston 8 advances under the action of the spring repulsive force and pushes the formed cover c back. The cover C that is pushed back will fall to the lower cover feeding means (slot) and be fed to the capping means. As described above, the cap forming apparatus of the present invention does not have a heating mechanism, and is capable of forming a cover by plastically deforming a resin-made plate-shaped covering material by cold forming. A major feature of the cap forming apparatus of the present invention is that a plurality of grooves or protrusions are provided on the inner peripheral surface of the forming die constituting the forming means, and/or a plurality of grooves or protrusions are provided on the outer peripheral surface of the punch. A plurality of grooves are formed on the inner circumferential surface of the forming die (Fig. 3). The plurality of grooves and protrusions disposed on the inner circumferential surface of the forming die are from the reference 89490-970901.doc 14- 1308896; from the angle of the fixed position, 'should be relative, and the same, the plural number of the convex surface The grooves and protrusions are also opposite. On the other hand, if a plurality of wrinkle guiding portions having different intervals are disposed in the gap between the inner surface of the forming die 7 and the outer peripheral surface of the convex concave mold 7, the plurality of grooves or projections disposed on the inner peripheral surface of the forming female die are disposed on the salient pole. The plurality of grooves or protrusions on the outer peripheral surface are also opposite. Further, when the projections are arranged on the outer circumferential surface of the forming die 45, the cross section of the projection front end 4 should be formed in an arc shape in advance. The punched cover material is folded between the outer peripheral portion of the punch 5 and the inner periphery of the forming die to form a cover c including the flat portion C1 and the portions C2, and the groove 73 is provided in advance. When the wrinkle guiding portion is used, the stress is concentrated on the plastic deformation due to the folding of P C3 , and the shape retaining property after the bending deformation is maintained, that is, the shape retention property is improved. Further, the groove or the projection ' disposed on the inner circumferential surface of the forming die or the convex surface * the circumferential surface is preferably provided in parallel with the protruding direction (advancing and retracting direction) from the viewpoint of the slidability of the punch 5. Further, the shape of the groove or the projection is limited to ', ', ''. However, in order to smoothly guide the formed pleats to the skirt portion C2 of the lid c: a lid is provided. For better shape retention, the groove or protrusion is preferably in the shape of an arc. In particular, when the shape of the mouth of the container is circular, the grooves or protrusions of the arc shape are arranged at equal intervals on the inner circumferential surface of the forming die or the outer peripheral surface of the skirt of the convex yoke k not only can be smoothly creased The skirt 4 C2' guided to the cover C gives the cover c a better movability and the appearance of the cover c. The η security is also conducive to the special limitation of the slip of the punch 5, and the width (size) and length of the c-protrusion are not the size of the melon, the thickness of the plate-shaped covering material, and the plate-like coating material. Make the appropriate settings for the material. The inner peripheral surface 71 of the sub-shaped concave bead 7 is subjected to a surface treatment to improve the slidability of the skirt portion C2 of the cover material 89490-970901.doc -15-1308896, and the stress is easily and smoothly concentrated on the bent portion C3'. Plastic deformation occurs, and in addition to improving shape retention, it is also possible to suppress breakage of the cover which occurs during the punch forming process. The surface treatment is, for example, hard ore chrome, plated collar, electroless ore, etc., but the surface of the cover material is further improved by a surface treatment which allows a small coefficient of dynamic friction. From the viewpoint of slidability, it is preferred to plate boron. Performing this surface treatment can not only improve the skirt of the cover material. The slidability also facilitates the formed cover. The mold release (release property) from the forming die 7. In addition, when the surface treatment is performed not only on the inner circumferential surface 71 of the molding die 7, but also the surface treatment is performed on the molding die opening portion 72, it is possible to prevent the resin powder from adhering to the resin-made plate-shaped coating material. In the case of forming the concave mold 7, not only the increase in the dynamic friction coefficient due to the adhesion of the powder but also the prevention of the mixing of the powder into the sealed container or the like can be prevented, which is also advantageous for the sanitary surface. The cover forming means of the present invention is not particularly limited as long as it has the above-mentioned forming die (mother die) and punch (male die), and as shown in FIG. 1, the forming means is provided with a cover with a spring 81. By reusing the piston, it is convenient that the formed cover can be automatically released from the forming die and dropped to the lower chute. However, for example, the formed cover is provided at the opposite side end of the punch of the forming die. When the suction device or the plate-shaped covering material is transferred in the horizontal direction and the end portion in the boring die is inserted from above to insert the punch, the cover push-back piston 8 is not required. Further, in terms of the gap between the forming die 7 and the punch 5 having the forming means for forming the female die and the punch, the minimum interval should be adjusted to 4'0彳0 or less of the thickness of the plate-shaped covering material', especially for adjustment. It is preferably 1.3 times to 3.5 times or less. When the gap between the forming concave core 7 and the punch 5 is 4 times or less, it is easier to plastically deform the cladding of the covering material and to form a resin-covered cover having shape retention, and the forming concave B9490-970901.doc -16-1308896 When the gap between the mold 7 and the punch 5 is more than 3 times the thickness of the covering material, especially 1.5 times or more, the coating material sheet can be further reduced to be damaged in the die cutting process. The cover material punching means of the present invention is not particularly limited as long as it can punch out one or two or more cover materials from the plate-shaped covering material. However, preferred examples include, for example, The movable blade 2 at the relative position of the forming die 7 and the punching means for the fixed blade 3 which is disposed at the outer peripheral edge portion of the forming die 7 at the height of the die face. Further, as shown in Fig. 1, the pressing member 4 of the plate-shaped covering material is attached to the flange portion 42' via a spring 41 so as to surround the outer peripheral edge portion of the movable blade 2; The coating material moves "to perform the punching process stably. Further, the cover forming device 1 of the present invention can also be applied as a part of a cap forming and closing device. The lid-forming sealed state of the present invention is not particularly limited as long as it has the following mechanism: it has a rewinding for winding the sheet-shaped covering material wound around the reel 9 shown in Fig. 5 a reeling feeding mechanism for the intermittent feeding material of the plate-shaped covering material for feeding the rewinding roller 1 (), and a retracting feeding method; Or a cover material punching means of two or more coffins, and a forming die and a punch formed by punching the cover material punched by the cover material, and provided on the inner circumferential surface of the forming concave core a die-cutting mechanism 12 for a plurality of grooves or protrusions, and/or a cover forming means for a plurality of grooves or protrusions outside the punch: a cover supply means 13 for feeding the formed cover C, and the above: The capping mechanism 14 of the crown capping means; and as described above, the second forming mechanism 12 does not have a heating mechanism, so that the cap forming cap can be realized = 89490-970901.doc 1308896 miniaturization. The molding method of the resin cap of the present invention is formed by punching out a resin sheet. The right horse is immediately pressed into the state of the forming die by abutting the covering material. Inserting into the forming concave mold, the skirt portion of the lid is formed in the gap, and the gap-cut lid member is formed into a lid shape, and the wrinkle is guided to the skirt portion of the lid to form a lid shape.

For example, the board should be tested according to the melon 7125. The static friction coefficient of the surface is 〇·ι~. The surface of the surface of the plate is made to have a resistance of 〇6 to 1〇14 Ω. For example, a surfactant such as a charge preventive agent or an antifogging agent is applied to the surface of the plate, and hydrophilicity is applied. A conductive material such as a polymer is used to form a charge-preventing layer, or a charge preventer or an anti-fogging agent is mixed into a resin to form a plate.
