A method of over-molding materials includes: providing a first material in a groove in a first portion of a mold such that only a single surface of the first material is exposed to a vacant portion of the mold; providing, via an injection molding process, a second material in a liquid form in the vacant portion of the mold adjacent to, and in engagement with, the first material; and allowing the second material to solidify and become directly coupled to the first material, thus forming a single component. During the method, the entire single surface of the first material is flush with a plane defined by outer surface of the first portion of the mold. The second material has one or both of a greater hardness when solidified than the first material and/or a higher melting temperature than the first material.

A dispenser (10) for dispensing flowable materials has a container (12) having an outer wall (16) and a membrane (34) collectively defining a first chamber (18) configured to contain a flowable material. The membrane (34) extends from the outer wall (16) at an angle. The membrane (34) has a thickness and a weld seam (40), and the weld seam (40) has a thickness less than the thickness of the membrane (34).

A childproof container apparatus, system and method. The apparatus, system and method may include a container body having therewithin a cavity; a cap capable of providing access to the cavity when opened; a collar about the container body and capable of impeding access to the cap; and at least one safety feature suitable, upon actuation, to allow the collar to slide to remove the impedance to accessing the cap. The container may further include a tamper evidencing feature at least partially physically associated with the cap. The at least one safety feature may include a plurality of tabs, or one or more buttons.

An in-mold lid closing apparatus includes a lid engagement member, a first actuation assembly connected to a first portion of the lid engagement member, a second actuation assembly connected to a second opposing portion of the lid engagement member, and a controller disposed in electrical communication with the first actuation assembly and the second actuation assembly. The controller is configured to transmit a first drive signal to the first actuation assembly and a second drive signal to the second actuation assembly to drive one of a linear position and a rotational position of the lid engagement member and to adjust at least one of the first drive signal and the second drive signal based upon a first feedback signal received from the first actuation assembly and a second feedback signal received from the second actuation assembly.

A container carrier and manufacturing method therefor are provided. The container carrier may include an integrally molded body with a plurality of annular structures. Each annular structure may have a top surface, a side wall, a circumferential rib, and a plurality of inwardly projecting flanges. The plurality of flanges may be collectively configured to secure a corresponding container within the annular structure. A first annular structure may be detachably coupled to a second annular structure by a tearable first tab, and a third annular structure may be detachably coupled to a fourth annular structure by a tearable second tab. The container carrier may be configured to separate into a first truncated carrier and a second truncated carrier when tearing operations are performed on both the first tab and second tab.

A method of forming a cap assembly comprises injection molding a cap in a first shot from a first polymeric material, wherein the cap has an opening at one end defined by a perimeter. Injection molding a tamper band in a second shot from a second polymeric material such that the tamper band is monolithically attached to the perimeter of the cap. The first polymeric material and the second polymeric material comprise dissimilar resins and the tamper band is configured to sever from the cap with no burrs remaining on the perimeter of the cap.

A vial is described herein that comprises a tubular body which comprises an opened end, a closed end, and a cavity, wherein the opened end is located at one end of the tubular body and the closed end is located at an opposing end of the tubular body. The tubular body further comprises a tear line located therein, wherein the tear line extends across at least a portion of one side of the tubular body, across the closed end, and across at least a portion of another side of the tubular body. In addition, the tubular body further comprises two flanges extending from the closed end, wherein the two flanges are configured to separate from one another outwardly from the tubular body and apply a force to break-open at least a portion of the tear line to open at least the closed end of the tubular body.

Disclosed is a process for manufacturing a safety closure, wherein in a first step, a monolithic injection-molded part is made having, one behind the other in the direction of a longitudinal axis (L), a rotary closure with a closure cap, a plurality of break-off points and an actuation piece, and in a second step, a force acting in the direction of the longitudinal axis (L) is applied to the injection-molded part such that the closure cap and the actuation piece move against each other in the direction of the longitudinal axis (L) and the closure cap slides at least partially into the actuation piece, the actuation piece being elastically deformed by the first engagement piece during the sliding-in movement so as to take an oval shape and then regaining its original shape once the sliding-in movement has been completed.

This nest comprises a plurality of breakable connecting bridges, a plurality of flanges arranged in a predetermined pattern and configured to form the flanges of the medical containers, the flanges being connected to the breakable connecting bridges, and a supporting structure attached to the breakable connecting bridges so as to support the flanges. The flanges are integrally formed with the breakable connecting bridges and the supporting structure.

A method of monolithically forming a flip-top cap from a thermoplastic material and a flip-top cap for dispensing a flowable dental substance. The flip-top cap has a base from which a dropper nose protrudes and a closure. The base and the closure are hingedly connected to each other by a living hinge for pivoting between a closed position, in which the closure closes the dropper nose, and an open position, in which the dropper nose is uncovered from the closure. The method has the steps of injection molding the flip-top cap in the open position in an injection molding device and positioning the closure and the base toward the closed position while the flip-top cap is still the injection molding device.
