摘要： PURPOSE:To bring a film in close contact with the side faces of an item to reduce the exudation of juice and improve the quality and appearance by a method wherein a vacuum chamber is heated, the bottom and the side face of a deep-draw film are brought in contact with steam, and the steam is forcibly recovered. CONSTITUTION:A bottom die 10 is elevated to tightly close a vacuum zone, and an upper vacuum valve 2 and a lower vacuum shut-off valve 19 are opened so that the inside of a vacuum chamber is evacuated. At this time, a steam valve 16 and a steam recovery valve 18 are closed. After a set evacuating time period passes, a sealing hot-plate 3 is lowered and the upper and lower films are heat-sealed together. The steam valve 16 is opened to blow steam into the bottom die 10, causing the steam to disperse into the vacuum due to the differential pressure. At this time, the lower vacuum shut-off valve 19 and the steam recovery valve 18 are kept closed to retain the steam only in the bottom die 10. The steam recovery valve 18 is opened to recover the steam to a steam blower 17. The exudation of juice is reduced because the film is brought in close contact with a product without loose-fitting of the film and longitudinal wrinkles on the side face.

摘要： PURPOSE:To reduce a packing cost, to effectively utilize the advantage of stretch package wherein a contained food is well watched through a package film, and to improve a freshness holding function by a method wherein a container or a food is wrapped with a high barrier properties plastic film in which an exhaust hole is formed, shrink package is effected, and sealing is effected by means of a label. CONSTITUTION:A deaerating hole 2 is formed in the bottom of a tray 1. Further, in the case of a food having a plenty of moisture contents, it is desired that the deaerating hole formed in the tray is formed in the side of the tray. Briefly, the position of the deaerating hole formed in the tray is properly set according to a kind and the size of a food. A food 4 is then contained in the tray 1. A high barrier properties plastic film 5 is shrunk in a heat tunnel. Finally, a label 8 is mounted on the back of the tray 1 for sealing so that the exhaust hole of the high barrier properties plastic film 5 is blocked. In which case, it is desirable that a material having a low oxygen permeability is used as the label 8.

摘要： PURPOSE:To make thick the arris sections of a container and prevent the generation of pinholes by preforming a raw film preheated by a preheater into the round tray shape by means of a molding heating plate and vacuumizing from below a mold to form a recessed section. CONSTITUTION:A raw film 12 preheated by a preheater 11 is reheated by a molding heating plate 13 having round tray-shaped sections 13a and vacuumized through a communicating opening 16a of a top force 16 of a mold section. The raw film 12 is stretched along the recessed sections 13a of the molding heating plate 13 by said premolding so that the wall thickness of a section covering the bottom section of a final molded container is made thinnest. Then, compressed air is fed into the top force 16, while vacuumization is carried out from a communicating opening 15a of a bottom force 15. As a result of said molding, the film wall thickness of a central part of a recessed section of the bottom force 15 is made thinnest, which makes the wall thickness dispersed in a coner section 15b of the bottom force 15 to uniformize the thickness of said surfaces 18a, a bottom surface 18b and arris sections 18c of a molded container 18 and eliminate pinholes of the arris sections 18c.

摘要： PURPOSE:To enable use of a container such as a deformable and thin tray and to eliminate loosening or overlapping at a sealing part by a method wherein the container and food are wrapped by high barrier plastic film which is formed with an exhaust hole, and heated on an upper part, then on a lower side and finally at both ends. CONSTITUTION:Food 4 is housed in a tray 1. Next, the tray 1 is wrapped with high barrier plastic film 5 to make lateral pillow wrapping. At this time, an exhaust hole 7 is formed in the high barrier plastic film 5 at a place which becomes a back surface of the tray 1. Then a lower side of the tray 1 is heated to make the high barrier plastic film 5 undergo a lower shrink. In this case, air and gas inside a pack are exhausted compulsorily by pressing the tray 1 on the upper surface with a compulsory exhausting conveyor 11. Next, an upper part of the tray 1 is heated to make the high barrier plastic film 5 undergo an upper shrink. Finally both end parts of the tray 1 are heated to make the high barrier plastic film 5 undergo both-end shrink.

摘要： PURPOSE:To prevent generation of defective sealing of a tray having slanted edges and round corners by a method wherein polystylene paper is used as material for a sealing part, and a sealing surface of a sealing receiving base and a sealing surface of a sealing frame are formed to slant at the same or an approximate inclination as the sealing inclination on the tray side. CONSTITUTION:A sealing surface of a sealing receiving base 1 and a sealing surface of a sealing frame are formed to slant at the same or an approximate inclination as the sealing inclination on the tray 2 side, polystylene paper is used as material for a sealing part, a tray 2 is put over the sealing receiving base 1, and the tray 2 and a film 3 are pressed down by a sealer 4 to carry out heat sealing operation. By this sealing method, even sealing can be obtained due to the cushion property of the polystylene paper, and therefore generation of defective sealing can be reduced.

摘要： PURPOSE:To ensure the supply of a skewer to a groove by reciprocating the whole skewer container having a hopper and to improve the accuracy of thrusting of a skewer by covering the top of the groove with the bottom wall of the container. CONSTITUTION:A skewer container 1 having a hopper 3 is provided with a skewer-passing slot 4 connected with the hopper at the bottom wall and the skewer container 1 is slidably supported on a base table 2. The base table 2 is provided with a groove 7 holding a skewer 5 passed through the slot 4. The skewer container 1 is reciprocated with a driving apparatus 10 between the 1st position where the slot 4 is connected with the groove 7 and the 2nd position where the groove 7 is covered with the bottom wall of the skewer container 1. A plunger having a part intruding in the groove 7 pushes the skewer 5 along the axial direction of the skewer with the intruded part and the skewer in pushed out of the container 1. As a result, the supply of the skewer to the groove can be ensured and the accuracy of the thrusting of the skewer can be improved.

摘要： PURPOSE:To enable positive labelling regardless of the shape of the surface of shaped body by making recessions allowing said shaped body to sink thereinto in the upper face of a base substance and interposing elastic forms freely deforming by pressure applied to the shaped body into said recessions. CONSTITUTION:Many parallel thin endless belts 2 installed on a fixed base substance 1 with specific intervals are exposed on the upper face of said fixed base substance 1 and a movable base substance 3 of comb-shaped end faces installed inside the fixed base substance 1 and capable of removal is interposed between the adjacent endless belts 2. Recessions 3a allowing shaped forms B to sink thereinto are made in the upper face of the movable base substance 3 and several parallel elastic forms, thin strip rubbers, 3b are stretched tight on the open top end faces of the recessions 3a. When labels A are mounted on the strip rubbers 3b and the shaped forms B are applied to the labels A, the pressure of application thereto forces the strip rubbers 3b to be loosened, therefore, the strip rubbers 3b come in contact with the surfaces of the shaped forms B over a wide range. Therefore, the surfaces of the shaped forms B are applied to the labels A over the whole width thereof and securely adhered thereto.
