This invention provides a method of bulging at least a portion of a sidewall of a drawn or drawn and ironed aluminum container body. The method involves an initial thermal treatment step prior to bulging. The thermal treatment is provided to that portion of the sidewall of the container that is to be bulged and is sufficient to reduce the yield strength of that portion of the sidewall about 20% without substantially adversely affecting the yield strength of the bottom wall of the container. After thermal treatment, at least a portion of the thermally treated sidewall is bulged at a circumferential strain greater than about 5% to provide container shape.

Method for partially annealing the sidewall of a container

This invention relates to an endwall for a container having a panel portion surrounded by a substantially vertical wall portion which terminates into a narrow rim. The rim is connected to a sidewall of the container. The wall portion extends outward from the container and is adapted to be reformed inwardly into the container in a controlled manner by an external mechanism to reduce the volume thereof after the container has been filled and sealed. The invention also relates to a method of packaging a product in a container having a body opened at one end and closed at an opposite end by an endwall as described above. The method includes the steps of filling the container with a product and sealing the open end, thermally treating the filled and sealed container, and reforming the endwall inwardly into the container. The sequence of steps can be rearranged.

Container recycling machine

An apparatus for the receipt of a recyclable container is disclosed. The apparatus includes a manually rotatable carrier having a container receiving station. The recyclable container is inserted into the receiving station where the presence or absence of a container having a metallic sidewall is determined prior to any movement apparent to the user. If the object inserted into the receiving station is determined to be a container having a metallic sidewall, rotation of the carrier for further processing of the recyclable container is permitted. The initial passive screening may include detecting the orientation of the container, detection for the type of metal sidewall, and may also include optical scanning of the container for reading a product code thereon.

Apparatus for passive analysis of containers to determine acceptability

Apparatus is provided for receiving and processing used containers including an enclosure with a rotatable carrier having one or more container receiving stations therein. Means are provided for detecting the presence of a container inserted into the receiving station. Means are also provided for crushing a container accepted for processing by the apparatus comprising a fixed crushing jaw and a movable crushing jaw adapted for dual engagement with a container to provide two stages of crushing.

Apparatus for processing used containers having improved crusher means

Apparatus is provided for the insertion of a recyclable container into a container receiving station in a manually operated rotatable carrier normally maintained in a non-rotatable condition; and for analysis and initial acceptance or rejection of the container for recycling without mechanical movement apparent to the user. The apparatus includes detecting means adjacent the receiving station to determine the presence of a container comprised of material acceptable for recycling and scanning means for reading code markings on the container. The information read from the code markings on the container may be recorded for subsequent use in determining amounts of deposits to be paid as well as sources of containers. Releasing means are provided for subsequently permitting movement of said rotatable carrier if said container comprises a material acceptable for recycling.

Container recycling apparatus using scanning means to read code markings

A process for recycling containers such as used aluminum beverage cans comprises sensing the presence of an acceptable container inserted into a receiving station in a rotatable carrier and unlatching a latching mechanism to permit the carrier to be rotated if the presence of an acceptable container is sensed. Rotation of the carrier conveys the container to a station where the container is crushed. A receipt is then issued for the crushed container. The process is controlled by a central control unit which may include a computer having a program to monitor and control the process steps.

Process for recycling containers

Apparatus is provided for receiving and crushing containers consisting essentially of recyclable material comprising an enclosure having a manually operated rotatable carrier with a first station comprising a pocket in the carrier to receive a container. Means are provided for detecting the presence of a container in the pocket and for detecting the type of material comprising the wall of the container. The apparatus also contains latching means to prevent rotation of the rotatable carrier until a container inserted therein has passed all tests performed in the first station. Means are also provided for measuring the weight of the container and for crushing metallic containers having a predetermined acceptable weight.

Apparatus for processing recyclable containers

Apparatus is provided for receiving and crushing containers consisting essentially of recyclable material comprising an enclosure having a manually operated rotatable carrier with one or more stations comprising pockets in the carrier to permit insertion of a container. Means are also provided to detect the presence of a container inserted into the pocket. Shock absorbing means are associated with the rotatable carrier to inhibit damage to the apparatus by rapid or jerking motions during rotation of the carrier to transport an inserted container to one or more subsequent stations for testing and eventual crushing of a container accepted for recycling.

Container recycling apparatus having shock mounted manually rotatable

Recycling apparatus for receiving and crushing recyclable containers is provided comprising a frame and an enclosure. A manually operated rotatable carrier is associated with the enclosure and has at least one open pocket therein to receive a recyclable container. The apparatus also is provided with detector means to determine the presence of a container in the pocket. Means are provided to lock the rotatable carrier to substantially prevent rotation of the carrier unless a container has been inserted into the pocket. Releasing means are also provided to permit rotation in response to actuation by the detector means when a container has been inserted into the pocket. The container is eventually crushed after rotation of the carrier to carry a container inserted into the pocket to a crushing station.

A wheel having a spider portion and a rim portion, a tire mounted on the wheel. The tire having a pair of sidewalls and an interposed, ground engaging portion. At least one anchor member secured to the spider portion and disposed on the inner side of the wheel. Traction members secured to the anchor member adjacent to one tire sidewall and extending beyond the tire ground engaging portion to the other sidewall. The traction member being secured adjacent to the other sidewall also.
