Apparatus utilizing pressurized liquid for testing containers such as soft drink beverage bottles for the ability to withstand internal pressure and for the absence of leakage. The pressurized liquid is introduced into each bottle with a swirling motion through an annular passageway and air is expelled from the bottle through a vent tube positioned coaxially within the passageway. The outer wall of the annular passageway is formed by a resilient sleeve which is compressed radially and extended axially by the pressurized liquid to provide a tight seal with the bottle. Pressure within the bottle is monitored by a sensing member which is displaced by the pressurized liquid and actuates a pivotally mounted lever arm which provides an amplified movement and corresponding to the displacement of the sensing member. In the disclosed embodiment, the apparatus is mounted on a rotary turret, and the introduction of the pressurized liquid and the expulsion of air are controlled by valves which are actuated automatically as the turret rotates between different positions.

Bottle testing apparatus

A one-piece blank forms a liquid-tight carton having plural rectangular side walls sealed or integral with one another at adjoining side edges and flat end panels of polygonal shape, the carton facilitating ultrasonic scaling of the end walls to the side walls through a unique set of sealing tabs on the side and end walls. The process and equipment for sealing the end walls to the side walls permits ultrasonic heating and sealing after the carton is full of liquid through a compression of the sealing tabs of these walls between facing dies which are diagonally aligned in relationship to the side and end walls. The carton formed by this blank facilitates nesting of multiple cartons, one above the other.

Continuous sealing rim for carton

A workpiece positioning mechanism (10, FIG. 1) includes a movable arm (12) having a plurality of joints (14). A pair of grippers (26 and 28) are movable toward and away from a semiconductor wafer boat (44). The grippers are held in position by a stop member (70, FIG. 4) when they engage the boat (44) and locked in an open position by prongs (86). A solenoid (30) is actuated to allow the grippers to move between their open and closed positions. Flexible bellows (22 and 94) and tubing (24) surround moving parts (e.g., 14, 62, 64, 66, 80) of the mechanism (10) to prevent contamination of the semiconductor wafers (52).

Workpiece holding and positioning mechanism and system

Machine for transporting and stacking cartons loaded with containers comprising two transport systems one above the other with restraining means to restrain motion of each loaded carton on one or the other or both systems, and pusher means which releases the restrained carton or cartons and pushes both of them in unison and with one above the other to a delivery point where the upper carton is deposited on the lower carton.

Machine for transporting and stacking loaded cartons

An apparatus and method is disclosed for forming a liquid-tight container having a rectangular cross-section formed from a one-piece, T-shaped blank of paperboard material. The carton preferably includes an access flap and straw element on one side thereof which, when manually lifted, exposes an end of the straw element from which the contents of the carton may be consumed by a user. The apparatus is compact in nature, possessing relatively few transport mechanisms which advance the T-shaped carton blank through a plurality of work stations. A novel method and apparatus for serially applying the straw element and access panel to the carton blank is disclosed, wherein the straw element and a length of polyethylene coated Mylar tape is automatically bonded to the carton blank upon a rotating heat sealing and alignment drum. A conveyor for collating a plural number of the carton blanks about a forming mandrel is also provided, and is positioned transversely to the remainder of the apparatus thereby significantly reducing the overall size of the apparatus. An ultrasonic welder bonds the side seams and end closure panels of the container upon a rotating crossbar mandrel which eliminates any misalignment during the sealing process. A substantially rigid conveyor transport carries a plurality of the carton blanks through pre-form, filler, and end closure work stations, and includes plural anvils for the ultrasonic welding process. An ejector mechanism is additionally provided which ejects the filled carton blanks from the rigid conveyor along a dual direction path, thereby eliminating the possibility of creasing or puncturing the filled and sealed container. The apparatus of the present invention additionally accommodates the production of differing size containers with only minor adjustments.

Method and apparatus for forming a container for liquids

A one-piece blank forms a liquid-tight carton having plural rectangular side walls sealed or integral with one another at adjoining side edges and flat end panels of polygonal shape, the carton facilitating ultrasonic sealing of the end walls to the sidewalls through a unique set of sealing tabs on the side and end walls. The process and equipment for sealing the end walls to the side walls permits ultrasonic heating and sealing after the carton is full of liquid through a compression of the sealing tabs of these walls between facing dies which are diagonally aligned in relationship to the side and end walls. The carton formed by this blank facilitates nesting of multiple cartons, one above the other.

Paperboard carton

Apparatus for testing bottles to determine whether they will withstand internal pressure as from a carbonated beverage, also for detecting flaws in crown of bottle which may result in leaks. Hydraulic pressure is applied internally by hydraulic fluid, usually water. Bottle is filled with low pressure water, then high pressure water is used to apply pressure. Bottle is held between a sealing chuck which contacts and seals crown and a bottom member bearing against bottom of bottle, thus simulating force applied to bottle during filling with beverage and capping. Means are provided to remove air displaced during filling with low pressure water.

Machine for testing bottles

Apparatus for forming a sealable carton for liquids accepts from a supply station a T-shaped blank of coated sheet material that is impervious to the fluid that the carton to be formed from the blank is to contain. The blank is pre-scored to delineate the side walls and ends of the carton and is further pre-scored to delineate tabs by means of which the sealing of the carton is to be effected. The apparatus for forming the carton includes a plurality of carton blank carriers mounted on a conveyor. As the conveyor carries the blank past a first operational station the side seam sealing tab is flexed forwardly and away from the mounting plate preparatory to the formation of a side seam. Following the positioning of the mandrel the blank is wrapped around the mandrel, two of the three exposed side panels of the blank being brought into surface contact with two of the faces of the mandrel and a third being brought into a position of angular confrontation with a face of the mandrel in which position its free edge spacedly confronts the side seam sealing tab that has been flexed. The carton blank carrier next brings the blank into registry with a source of heated air directed between the flexed side seam sealing tab and the inner surface of the side panel that is confronting the sealing tab. The sealing tabs at the end of the tube that will be closed to form the bottom of the carton are brought into association with a system of rollers which flexes the three sealing tabs toward positions where they may be engaged by the closure panel of the tube that has been left exposed by the mandrel. The carton blank carrier next transports the carton past a source of heat which is directed on the outer surfaces of the sealing tabs and the inner surface of the closure panel that has been brought into proximity to the sealing tabs. Following completion of the closure of one end of the carton the mandrel is withdrawn and the open-ended carton is released from the blank carrier for storing or for delivery of the carton to carton filling equipment.
