A method for producing a package closure (10) having a neck (18), a cap (19) and an axis (A), comprising the steps of a) by means of movable jaws (11, 12) and a tool core (14) forming the neck (18) with an outer thread (21 ) and the cap (19) with an inner thread (26), wherein an interior of the neck (18) is formed by an outer first tool core part (16), and wherein an interior of the cap (19) is formed by an inner second tool core part (17) and a third tool core part, the thread (26) of the cap (19) being formed by the third tool core part, b) removing the jaws (11, 12) from the formed package closure (10), c) axially displacing the second tool core part (17) in relation to the first tool core part (16) and thereby separating the cap (19) and the neck (18), d) axially displacing the third tool core part in relation to the second tool core part (17) and thereby disengaging the cap from the third tool core part while keeping the second tool core part (17) engaged with the cap (19), e) displacing the neck (18) axially in relation to the cap (19) and bringing the thread (26) of the cap (19) into engagement with the thread (21) of the neck (18) through an inherent flexibility of the package closure (10) to form a package closure having a cap (19) mounted on the neck (18), and f) displacing the package closure (10) in relation to the second tool core part (17) to disengage the package closure (10) from the tool core (14). The invention is also related to a device for production of the package closure (10). Disclosed is also the package closure (10) produced by the method.

A moulding machine suitable for producing an article having two or more parts, the moulding machine comprising two or more mould sections for respective article parts and an in-mould pick and place mean. A moulding machine including one or more moulds and a robot pick-and-place system, in which the robot pick-and-place system is fixed to a mould. A method of forming an article having two or more parts, in which a first part of the article is moulded in a first mould section of a moulding machine comprising two or more mould sections for respective article parts and an in-mould pick and place means, and the in-mould pick and place means moves a moulded first part of the article from the first mould section to a second mould section of the two or more mould sections.

A preform can be made from two different materials that do not bond together by a bi-injection process, using the same mold. An outer preform can be fashioned first, then an inner preform molded through a center hole in the outer preform's bottom. The preforms are then connected. Inner/outer preform materials can be different, e.g., PET/polyolefin or polyamide, or the same, e.g., PET/PET—if mutual bonding during the molding of the second is prevented. A non-stick coating can be sprayed on a surface portion of the first preform touching the second perform, then the second container molded. Manufacturing order can be either outer/inner, or inner/outer, and the non-stick coating sprayed on the inside/outside of the perform first molded, followed by molding of the other.

An example lid assembly can include a lid and a slider. The lid can include a wall defining a recess. The slider can be configured to slide in the recess and can be configured to move between a closed position where the slider covers the opening to aid in preventing spilling of contents of the container and an opened position where the slider uncovers the opening such that the contents of the container can be consumed. The slider can be configured to be removable from the lid and can be replaced back on the lid. Additionally, the slider can be configured to lock into place on the recess in both the closed position and the opened position.

A seal and method of forming a seal for a resealable container includes a removable cap that is selectively received over a pour opening formed in a can body. A seal is adhered to the end wall of the cap and includes a continuous, first axial region extending outwardly from the inner surface of the cap. The seal first region is dimensioned for engagement with the opening in the container and sealing the container along an inner diameter thereof. Reduced on-torque/off-torque are required since the seal is formed on the inner diameter, and a down force is substantially reduced to assemble the cap to the container.
摘要:
A metal cap in which a liner to be held to a cap body and separable from the cap body can be formed by a series of operations for forming the cap body and press molding the liner. The liner 3 of the metal cap 1 has a double-layer structure consisting of a barrier layer 20 on a top panel wall 5 side and a sealing layer 21 on the inner side of the cap body 2, and the barrier layer 20 is temporarily bonded to the top panel wall 5 with a weak adhesive at the time of molding the barrier layer 20 and separated from the top panel wall 5 by the natural cooling of the barrier layer 20 after molding.

The present invention relates to a cap for a container. The cap comprises a main body having a top plate and a circular sidewall, wherein one periphery of the circular sidewall connects to the top plate forming a closed end, and the other periphery of the circular sidewall at the opposite side of the closed end forms an opened end; and a ring member located at the opened end of the main body, separated from the main body by a first incision line, and connected to the main body by a plurality of connecting portions, wherein a plurality of second incision lines locate on the main body or the ring member and locate at one side of the plurality of connecting portions. The cap provided by the present invention will, while in its open and/or closed state, continue to be connected to its container.
