METHOD FOR COATING PREFORM FOR PLASTIC BOTTLE
In slot-die coating, shrinkage of a PVA film when heating after the application of a PVA solution onto an anchor layer formed on the outer surface of a preform for a plastic bottle is suppressed. A leveling agent such as a siloxane is added to the PVA solution.
Agricultural stake to support plants and associated methods
An agricultural stake to support plant includes a fiberglass reinforced plastic (FRP) elongated member comprising a top end and a bottom end, and an exterior coating impregnated with an aggregate covering an exterior surface of the elongated member. The exterior coating is configured to provide purchase to a line attached to the elongated member. A cap may be secured over the top end of the elongated member and is configured to withstand a force used to drive the elongated member into a ground surface.
Nozzle for blow-molding stepped finish preform
An apparatus for a nozzle is provided for engaging with lightweight preforms for blow-molding the preforms into plastic containers without damaging the finish portion of the preforms. The nozzle comprises a first cylindrical portion including a first seal, a second cylindrical portion including a second seal, and a tapered portion between the first and second cylindrical portions. The first and second cylindrical portions include diameters that are less than respective diameters of interior surfaces within the finish portion. The first and second seals are disposed around respective circumferences of the first and second cylindrical portions and configured to tightly engage with the interior surfaces of the preform while maintaining clearance between the nozzle and the interior of the finish portion. In some embodiments, the seals are configured to stabilize an orientation of the preform after being pressed onto the nozzle and facilitate conveying the preform along a manufacturing line.
COMPOSITE PREFORM, COMPOSITE CONTAINER, COMPOSITE PREFORM, PLASTIC MEMBER, AND METHOD FOR PRODUCING COMPOSITE CONTAINER
A composite container which can be given various functions and characteristics; a method for producing such composite container; a preform; and a composite preform. A composite container according to the present invention that includes a container body which is made of a plastic material; and a plastic member disposed on the outer surface of the container body, wherein the container body and the plastic member are integrally inflated by means of blow molding, and wherein the plastic member includes a colored layer and/or a print layer where a print is made.
COMPOSITE PREFORM, COMPOSITE CONTAINER, COMPOSITE PREFORM, PLASTIC MEMBER, AND METHOD FOR PRODUCING COMPOSITE CONTAINER
A composite container which can be given various functions and characteristics; a method for producing such composite container; a preform; and a composite preform. A composite container according to the present invention that includes a container body which is made of a plastic material; and a plastic member disposed on the outer surface of the container body, wherein the container body and the plastic member are integrally inflated by means of blow molding, and wherein the plastic member includes a colored layer and/or a print layer where a print is made.
Liquid blow molding apparatus and liquid blow molding method
A liquid blow molding apparatus comprises: a mold (4) in which a preform (2) is to be placed; and a nozzle unit (6) having a supply port (9) capable of supplying a liquid from above into the preform (2) placed in the mold (4), wherein the nozzle unit (6) includes a seal body (13) that is movable among a closed position at which supply of the liquid through the supply port (9) is blocked, a first open position at which supply of the liquid through only part of the supply port (9) in a circumferential direction is allowed, and a second open position at which supply of the liquid through the whole supply port (9) in the circumferential direction is allowed.
Blow moulding machine, preforms, system and process
A continuous non-symmetric preform feed stretch-blow-moulding machine dedicated to the stretch-blow-moulding of containers from non-symmetric injection moulded preforms; the non-symmetrical preforms including an integral handle extending from a first junction point to a second junction point on a body of the preform; the body of the preform and the integral handle constituted from the same material.
Divergently vented aerosol dispenser outer container therefor and preform therefor
An aerosol dispenser, an outer container for an aerosol dispenser and a preform for an outer container. The aerosol dispenser, outer container and preform each have a neck, which in turn has a crimp ring, to receive a valve cup clinched thereto. The crimp ring has slots which act as vents therethrough. The vents may be exposed to pressurized propellant and product due to deformation of the neck during undue internal pressurization. The cross section of the vents diverge in the downward direction to provide both flow area and for product and propellant and adequate area for the valve cup to be corrugatedly clinched to the crimp ring.
ONE PIECE MULTILAYER THERMOPLASTIC CONTAINER HAVING A COLORANT
A container formed of a common one-piece multilayer thermoplastic substrate. The container wall has an outer layer and an adjacent underlying layer. And the underlying layer has a colorant visible through the outer layer. The colorant in the underlying layer can be one or more pigments and or one or more dyes.
SYNTHETIC RESIN-MADE CONTAINER, PREFORM, AND METHOD OF MANUFACTURING SYNTHETIC RESIN-MADE CONTAINER
A synthetic resin-made container has an outer layer body and an inner layer body separably laminated on an inner surface of the outer layer body and is formed by stretch blow molding, and has: a tubular mouth portion; a shoulder portion located below the mouth portion and increasing in diameter downward; a barrel portion connected to and located below the shoulder portion; and a bottom portion closing a lower end of the barrel portion, wherein the mouth portion has an outside air introduction hole for introducing outside air into a space between the outer layer body and the inner layer body, and the inner layer body is made of a crystalline resin, and has, in at least a part of the mouth portion in the inner layer body, a crystallized region having a higher degree of crystallinity than other regions.
