摘要:
A resin-coated metal plate having a metal substrate and, formed on the surface thereof, a thermoplastic resin layer, characterized in that the thermoplastic resin layer comprises a polyester containing polyethylene terephthalate as a main component and an ethylene polymer and further comprises tocopherol or a derivative thereof. The resin-coated metal plate exhibits good corrosion resistance and impact resistance (dent resistance) together with good resistance to an atmosphere of both high temperature and high humidity, and thus can be subjected to retort sterilization and can be held in a hot vender after retort sterilization.

Microprotein-inactivating ultrafine metal particles comprising ultrafine metal particles having a bond between an organic acid component and a metal, having an infrared absorption peak ascribable to the bond between the organic acid and the metal near 1518 cm -1 , and capable of efficiently inactivating microproteins without impairing properties of the resin or formability thereof. When used in the form of a resin composition or a coating agent, the microprotein-inactivating ultrafine metal particles are capable of exhibiting an effect for inactivating microproteins.

A polyester container furnished with a flange part having mechanical strength, transparency and heat resistance through orientational crystallization, which polyester container exhibits low-temperature heat sealability, is provided by disposing a projecting portion at a crystallized upper surface of flange part, the projecting portion at at least heat-sealing-face constituting region rendered amorphous or of low crystallinity. Further, in order to suppress variation of strength of sealing with a cover member and stably attain high sealability, the projecting portion is deformed at the time of heat sealing with the cover member so as to form a resin piece protruding toward the interior of the container while being substantially in close contact with the upper surface of opening rim part. The formed resin piece couples with a sealant layer of the cover member.

Disclosed is a readily degradable resin composition having excellent biodegradability. Specifically disclosed is a readily degradable resin composition comprising: an aliphatic polyester (A) which has biodegradability; and an aliphatic polyester (B) which has a solution viscosity (η inh) of 0.25 dl/g or less as measured in a mixed solvent composed of m-chlorophenol and 1,2,4-trichlorobenzene at a weight-based ratio of 4:1 at a concentration of 0.4 g/dl and at a temperature of 30°C and a melt viscosity of 50 Pa S or less as measured at 190°C at a shear rate of 1 rad/s and is capable of biodegraded at a more rapid degradation rate than the aliphatic polyester (A). Also disclosed is a readily degradable resin composition comprising: an aliphatic polyester (A) which has biodegradability; and an aliphatic polyester (B') which, when hydrolyzed, can release an acid showing a pH value of 2.0 or less when dissolved in water at a concentration of 0.005 g/ml and is capable of biodegraded at a more rapid degradation rate than the aliphatic polyester (A). Further disclosed is a biodegradable container comprising the readily degradable resin composition.

[Problem] A filling nozzle is provided which has a high flow straightening effect and is capable of forming a stable liquid flow of a circular cross section. [Solution] In a filling nozzle in which a flow straightening member for straightening the flow of liquid is arranged in a hollow nozzle body 2, a flow straightening plate 3 with a multitude of fine holes 5 formed therethrough so as to pass the liquid therethrough is used a the flow straightening member, and a divergent chamfered portion 7, which act as a guide means for guiding fine streams of liquid flowing out from adjacent individual fine holes 5 in a direction to bring them into contact with one another, is formed on an opening edge of an outlet of each fine hole 5 on an outlet side surface 6 of the flow straightening plate 3.

In a first mode for carrying out the invention, a coating layer (3) for coating a container body (2) is formed. The coating layer (3) disappears, while continuously and gradually reducing its thickness at a reduction rate of 0.1 - 1.5 μm/mm, from a coating layer formed portion (4) toward a portion (5) where the coating layer is not formed. Further, the coating layer (3) has a thickness reduction section (6). The thickness reduction rate of the thickness reduction section (6) is 0.1 - 0.5 μm/mm from at least a portion at which the coating layer (3) disappears to an area of a height of 30 mm, the area being an area immediately before the coating layer (3) disappears.

A hot-melt composition comprising a thermoplastic elastomer, a tackifier, a wax and a polyolefin resin, the wax having a softening point (R & B system) of 140 to 160°C. The hot-melt composition can be easily applied to the mouth-neck portion of a metal can and can be excellently produced. Even when placed under a high-temperature condition, the sealing material that is formed exhibits excellent heat resistance maintaining the sealing.

Provided is a branch type standing pouch in which an opened nozzle can easily be stood without necessity of special members or processes, and in addition, the opened nozzle can stably be maintained so that contents thereof can easily be poured out. The branch type standing pouch comprises: a pouch front side member including a pouring-out nozzle backside portion which constitutes a backside of a pouring-out nozzle by being folded back and a pouch body front side portion continuous therewith; a pouch backside member constituting a backside of the pouch body; a pouring-out nozzle front side member; and a bottom member, wherein: the pouch front side member, the pouch backside member, the pouring-out nozzle front side member, and the bottom member being respectively formed of plastic film and heat-sealed to each other so that a pouring-out nozzle is formed in a branched manner from a top of a pouch body. In this pouch, two symmetrical nozzle reinforcing areas are formed on both sides of a first protrusion as a result of a provision of the first protrusion at a central upper portion of the pouch front side member, extending from a center of the pouring-out nozzle backside portion to a central upper portion of the pouch body front side portion beyond a fold-back portion, and of a provision of two symmetrical second protrusions on both the sides of the first protrusion, a third protrusion extending in a longitudinal direction of the nozzle is provided at a center of the pouring-out nozzle front side member, a fourth protrusion is provided on an extension line from the third protrusion at a central upper portion of the pouch backside member. As a result, the branch type standing pouch in which the pouring-out nozzle can be fixed upright at a time of opening is obtained.
