Abstract: The present invention is directed to an apparatus for loading stacks of container lids into an associated lid-applying apparatus, as typically found in a container filling facility. The apparatus includes a reciprocably movable carriage which is positioned generally above the lid-applying apparatus. The carriage can be positioned in a first, loading position, which is generally offset from the apparatus for convenient placement of the lid stacks by operators. The carriage can then be moved over the lid-applying apparatus to a second, unloading position. The carriage includes movable lid supports, which then open to release the lid stacks downwardly onto the lid-applying apparatus. In the preferred form, vertically movable lid cradles extend upwardly from the lid-applying apparatus, and receive the lid stacks from beneath carriage. The cradles then move downwardly, carrying the lid stacks downwardly, for transfer of the stacks onto the lid-applying apparatus.
Abstract: A method and capping apparatus is provided for securely seating a closure with curvilinear top surface onto a container in a manner that avoids damage from excessive force applied to the closure. The apparatus has a cap locking unit with a circulating compression belt that contacts a top surface of the closure/container as the combination is being transported from underneath by a conveyor. A dancer contacts an inner surface of the compression belt. Pressure is applied from the dancer through leading and trailing leg components that converge from a common pivot. Ends of the leading and trailing legs are spaced from one another less than the length of the closure. Force is applied to the closure by simultaneous pressure from both legs on different first and second areas of the closure top surface.
Abstract: A method and apparatus for capping blown containers is provided. The top surfaces of a snap-on cap are preferably engaged sequentially by pressure members that traverse different segments thereof. The pressure members urge the cap over the neck of a container as they traverse the cap. The pressure members are preferably mounted to a support that is positioned above an initially loosely capped container, and resiliently urge the cap in a downward direction. The pressure exerted by each pressure member on the cap may be adjustable. The surfaces of the pressure members for engaging the cap are preferably substantially spherical.

Abstract: A cartridge of wound-up photographic film has an elongate housing within which the film is received, the housing having an outlet through which the film leader projects. In order to insert the cartridge of film into a cylindrical container it is necessary to wrap the film leader around the housing of the cartridge. A method of inserting the cartridge into the container involves conveying the cartridge into the open end of the container whilst simultaneously rotating the cartridge about its longitudinal axis so that the film leader is brought into engagement with the rim of the open end of the container whilst it is rotating. This causes the film leader automatically to be wrapped around the housing of the cartridge to permit the ready insertion of the cartridge and the film leader into the container. An apparatus for automatically performing the function of inserting the cartridge into the container using this method is also described.

The ridge provides a uniform taper in the outside diameter of the lid, enabling containers to be capped at high speeds by a method that utilizes a spinning rod feed mechanism. The ridged lid is formed by a novel method, utilizing a one-piece mold cavity, fitted with a one piece mold insert. Also disclosed is a method of fabricating the one-piece mold cavity.
Abstract: Apparatus and method for applying resiliently self-latching lids to upwardly open containers such as molded plastic buckets used to contain powdered or liquid products, in which a supply of generally planar circular lids is supported in a shallow sloping stack in which individual lids are on edge and supported on parallel sloping rails. Lids are released individually into a lid placement guide which may include a reciprocally rotating mechanism to orient each lid to place a pour spout of the lid in proper position relative to a bail of the container. Containers are carried beneath the lid placement guide on an endless belt conveyor to receive lids. A powered presser roll forces the lid into mating relationship with each container, without overturning empty containers receiving the lids.
Abstract: This invention shows two mechanisms for receiving, separating, delivering covers to a gravity chute, and thence to metering and cover-positioning and -pressing means. The feeding of covers may be automatic or may be hand-loaded. One embodiment shows the separation mechanism employing Y-members that are actuated by a reciprocated ring with jaws and guide supports in a common plane. Adjusting means for size and cover thickness, both metal and plastic, is contemplated. The other mechanism utilizes jaw arms that are stacked one above the other and preferably are arranged as four pairs, with upper arm jaws moved by one cycled ring and the lower arm jaws moved by another cycled ring. Vacuum cups remove and carry the removed cover to a gravity chute and a metering and cover-pressing apparatus that provides insured placement of only the forwardmost cover on a traveling container. Orienting means is also contemplated, and plural delivery chutes are shown. A height-adjusting means is also depicted.
Abstract: An apparatus and method for automatically placing large plastic lids onto containers. Lids 24 are dispensed individually from magazine 11 onto slide 33. Each dispensed lid is individually retained at the bottom of the slide 33 for pickup by a container 41. The lid is urged onto the container by a pivoted roller 47 and further leveled by a roller 58 which is extended twice by a pneumatic piston to first contact a leading edge of the lid and to secondly contact a trailing edge of the lid. Thereafter a pneumatically operated lid securement means 61 comprising a convex plate 70' burps the air from beneath the lid and fully seats the lid on the container. The apparatus has various sensing means for sensing the depletion of lids from magazine 11, for sensing that a lid has been dispensed onto slide 33 and for sensing a container at the capping station. The sensing means control the various operations of the machine in proper sequence.
Abstract: A machine for applying lids to containers and for further heat sealing a metal foil membrane to each container beneath its lid includes a main conveyor and a timing screw at the feed end of the conveyor for releasing open top containers onto the conveyor at equally spaced intervals. As the containers move along the main conveyor, captivator blocks, which are carried on synchronized chains located at each side of the main conveyor, converge toward and close upon the side walls of the containers so as to confine the containers in the horizontal direction while they move along the main conveyor. Lids are applied to the containers at a lid applicator while the containers are gripped by the captivator blocks. Thereafter the containers pass beneath an overhead belt and the lower pass of this belt is backed by a pair of skid plates and a plurality of rollers, with the rollers being interposed between the two skid plates.
