SECTION I - CLASS DEFINITION

This class is the generic class of apparatus for and methods of encompassing, encasing or completely surrounding goods or materials with a cover made from sheet material stock.

(1) Note. This class does not provide for methods of permanently encompassing, encasing, or immobilizing hazardous or toxic waste. Methods of packaging binding and immobilization of hazardous or toxic waste for the sole intent of permanently containing the waste are found elsewhere. Methods of packaging to move potentially hazardous or potentially toxic materials through commerce where the materials are removed from the container for subsequent use or treatment are proper for this class (53). This class is also the generic class of apparatus for and methods of partially encasing or surrounding goods and materials by a partial cover made from sheet material stock, which completely encircles and is in frictional contact with the goods or materials so as to be retained thereon. This class is also the generic class of apparatus for and methods of assembling and/or securing a separate closure (hood, cap, capsule, crown, seal, cork, disk, cot, etc.,) to the aperture of preformed receptacle so as to complete the encasement of contents. Assembling includes any manipulation or handling of the receptacle resulting in the sealing of a filling orifice by the closure. This class is also the generic class of apparatus for and methods of depositing articles and arranging fluent materials in preformed receptacles. See subclasses 235+. This class is the residual class of apparatus for and methods of subjecting the contents to a treatment before, during or after packaging combined with the packaging operation not otherwise provided for. Treatment includes plural diverse manufacturing provided for elsewhere (see References to Other Classes below) This class is also the generic class for apparatus for, and processes of, making match books. This class also includes apparatus for exposing the contents of a package by opening one or more folds of the cover. The apparatus and processes in this class include the shaping of the cover about the article, the partial or complete shaping of the cover followed by a filling operation, the filling of a preformed receptacle with articles and the filling of a preformed receptacle followed by a closing operation. The apparatus and processes in this class include the application of wrappers and encircling bands and labels, and the application of partial covers encircling the contents. The apparatus and processes in this class may include the making of the cover prior to packaging and/or the treatment of cover before, during or after packaging.. The apparatus and processes in this class include the printing and/or embossing of the contents and/or the cover, the coating of the package, the making and/or applying of cover opening adjuncts such as tear strips, and the application of a strand, handle, strip, stamp, and/or label to the package. The apparatus and processes in this class include the association of articles into groups for packaging, and also include the packaging of individual units followed by a grouping of such units for further packaging, whether or not the further packaging is claimed. The apparatus and processes in this class encase or encompass goods and materials with a cover, which serves for identifying, protecting or unit handling the goods or materials. The cover is usually removable from the contents when the latter is used. However, some exceptions are found to this removal including, e.g., match books, capsules and tea bags. EXPLANATORY NOTE ON SCOPE OF CLASS Class 53 was designed with the purpose of recognizing that the packaging of manufactured products so that they may pass through the channels of trade in a safe, convenient and attractive condition, is an art deserving of a separate status in the system of classifying inventions. Heretofore, for the most part, the packaging operation was treated either as an appendage to the manufacture of the product to be packaged or as a special instance of container manufacture. Neither was in accord with the activities of those who devise packaging machinery or processes, who are neither the manufacturers of the product nor of the packaging materials. Where patent claims include subject matter limiting the process or apparatus to use in manufacturing a particular article other than as specifically provided for in the definition below such patent is excluded from this class and will be found in the class best providing for making said article. If the claims merely recite, by name, the article being manufactured but the process or apparatus is of general utility, such recitation alone will not exclude the patent from this class. Since it is not desirable to withhold from use those portions of the reclassification which can be completed and handled as a unit, Class 53 was established even though numerous inventions pertaining to the art of packaging are as yet represented therein only by search notes to other classifications. The art relating to filling and closing and closing, per se, of preformed receptacles, and depositing articles in preformed receptacles, formerly classified in Class 226, Filling and Closing Portable Receptacles, is now classified in appropriate subclasses of this class (53) unless otherwise excluded by the notes to the various subclasses herein.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

A. PACKAGING AND BINDING ELSEWHERE CLASSIFIED

Banding apparatus is found in this class, subclass 582 and the corresponding processes are found in subclass 399. Banding machines and processes, either, per se, or combined with other machines or steps, are also found in many places; for which see the search notes below to Textiles: Presses; and Tobacco.

Combined packaging and binding apparatus is found in this class, subclasses 138.6+, and corresponding processes are found in subclasses 410+. Because the related arts have often treated banding and binding as equivalents, the references to the Binding art refer back to this section, rather than to the section on Other Covering, below. Binding machines and processes, either per se or combined with other machines or steps, are also found in many places, see the notes under Search Class to classes for textiles: manufacturing; harvesters; presses; manufacturing container or tube from paper; or other manufacturing from a sheet or web.

Since practically all packaging and binding elsewhere classified includes not only packaging and binding, per se, but the combination therewith of other devices or steps no attempt to distinguish between the references to packaging and binding, per se, and to combined packaging and binding, has been made.

Methods of packaging, binding, and immobilization of hazardous or toxic waste for the sole intent to permanently containing the waste are found in Class 588. Methods of packaging to move hazardous or toxic materials through commerce where the materials are removed from the container for subsequent use or treatment are proper for Class 53.

See References to Other Classes below that reference this section.

B. OTHER COVERING

Since covering is a form of assembly, reference is made to the notes to Class 29, Metal Working, See the Search Class note below referencing this section.

Because the related arts have often treated banding and binding as equivalents, references to the binding art have been placed in "Packaging And Binding Elsewhere Classified," above, rather than in this section. See References to Other Classes, below, that reference this section for other covering classes.

C. PACKAGES, AND PACKAGED AND BANDED ARTICLES

Capsules are found in several other classes. See References to Other Classes, below, that reference this section.

D. PACKAGING AND BINDING SUBCOMBINATIONS

See the article dispensing class for article dispensers (feeders) not otherwise provided for.

For cutting and/or scoring sheets for cover blanks, and for cutting combined with form-scoring; and for form-scoring generally of a sheet or web, see the Search Class references below.

SECTION V - GLOSSARY

BAND

A species of cover in which the cover material completely encircles the contents in one direction only, such as girth, leaving the contents fully exposed on two sides or ends, and which is in frictional contact with the contents so as to be retained thereon. See "BINDING".

BINDING

The embracing by means of a filament, strand or wire of either an accumulated bunch of articles, a series of coils, or a single encased package. It differs from banding in that no substantial area of the contents is covered, and the binder is usually tied, knotted, or twisted. Except where applied to a package for this class, (see subclass 138.6), the process of and apparatus for applying a binding is not here classified. See "Packaging and Binding Elsewhere Classified" of the Class Definition for binding, per se.

CLOSURE

A species of cover in which a separate cover member completes the encasement or confinement of contents within a preformed receptacle when said member is assembled within, over or around the aperture of said receptacle.

CONTENTS

The goods or materials which are, or are to be, confined within the space defined by the cover of the package, An insert sheet or coupon, to be packaged with other goods is considered to be a part of a group contents. See "GROUP FORMING". A package resulting from a first packaging operation may become the contents of a second packaging operation.

COVER

A member, made from sheet material stock which serves to confine the contents by either a complete encasement or a partial encasement, and which fully encircles or encompasses the contents in at least one direction. A band, closure, preformed container, carton or receptacle, though said members are not "made from sheet material", are each considered covers for this class. A spindle or core which extends into or through a preformed aperture in the contents is considered to be a partial cover. See subclass 581. See "BAND", "CLOSURE", and "RECEPTACLE".

COVER-ADJUNCT

Some accessory, device or abiding characteristic which is supplied to, or formed integral with, a cover to perform some function in addition to the mere enclosing of the contents. Such adjuncts include the addition to a cover of (1) a filament, strand, wire, stamp, label, handle, or display support, (2) a filler piece for the gap resulting between two or more folded flaps, (3) some auxiliary cover seam retaining device, including a staple, a clip, a sewn stitch, or a simultaneously integrally formed and set tab-and-slot retaining means, (4) a coating, printing, embossing or other marking, ornamenting or display feature, (5) some means to provide for opening the cover such as, e.g., a tear strip, (6) a cover attached reinforcement, article holder, or article remover, or (7) a window or window opening, (8) a contents contacting sealing spot, disc or gasket, (9) a superimposed disc which is applied to a hood or cap so as to depress said disc and a portion of the hood or cap within the aperture of a receptacle, (10) a cam actuated sealing or gripping means on the closure for fastening said closure, or (11) a protection strip placed over the contents of a receptacle (e.g., matches) and inserted between the side of the receptacle and the contents. However, the operations of slitting or notching of cover blanks and flaps preparatory to the shaping of the cover, or the application of adhesive to the cover to aid in seam retaining are not considered cover-adjuncts for this class. Nor is the addition of a transitory characteristic to a cover for the purpose of aiding in the packaging, e.g., the addition of moisture to a wrapper, considered to be a cover-adjunct.

FEED

Feed or delivery, as distinct from infeed, is transfer, conveyance, movement or translation of assembly components to or from what is established as a work position; at which position further motion of the components with respect to each other - generally a straight line movement along the major axis of either or both components - is called infeed. Thus, for example, motion of a closure element from a hopper or magazine to a superimposed position over the aperture of a receptacle is referred to as feed or delivery while the final juxtapositioning of the closure and receptacles previously aligned and oriented is considered infeed.

FILLING

The step of placing a contents within a cover. It is not necessary that the contents occupy the entire space encased; i.e., the cover may be only partially filled by a filling operation.

GROUP FORMING

The accumulating or gathering of an associated collection of articles, of the same or of different characteristics, by means of a plurality of feeding operations, for placement as a contents in a single cover. An insert sheet or coupon to be packaged with other goods is considered to be an article of different characteristics from the goods. On the other hand, an inner cover, or a section of plural section cover is not considered to be a part of the contents of an outer cover. See "CONTENTS".

HEADER

The means to either (1) hold and position, (2) hold and secure, or (3) juxtaposition and secure a separate closure element during infeed.

INITIAL WRAP

The wrapping of a cover around a contents to form a package is invariably done in two stages, viz.: first, the shaping of the cover about a single end or surface of the contents, and second, a further shaping of the cover by bending or folding the previously unfolded portions thereof so that the latter portions are in contact with the contents end or surface opposite to the end or surface about which the cover was previously shaped. The intermediate state of the cover at the end of the first stage is referred to as the Initial Wrap. The initial wrapping operation begins with the contact between the first end or surface of the contents with the cover and proceeds in two ways, either by (a) an unidirectional relative movement (which is not necessarily continuous) between the folding instrumentalities and the cover material-contents unit or (b) by a first relative movement between the folding instrumentalities and the cover material-contents unit, and one or more succeeding relative movements therebetween, at least the first of which is in a direction different from the first movement, and which serves to complete the shaping of the cover along the first end or surface of the contents without bending or folding the remaining unfolded portions of the cover into contact with the opposite end or surface of the contents.

PACKAGE

A unit consisting of an assembled cover material and contents, where the contents is, or is to be, encased or encircled by the cover material. The cover need not be shaped around the contents, e.g., the unit resulting from the final positioning of a contents upon a cover blank or web, which is then handled as a unit through further packaging operations including an encasement or encirclement, is also termed a package.

RECEPTACLE

A stage of cover formation in which the cover material has been fashioned into such shape as to at least partially confine the contents, as for example, against lateral displacement. A sheet of bendable or foldable cover material which has received a single preliminary fold, such as a U-fold, as well as a completely formed carton, are both considered to be receptacles.

SEAM

Two or more edges of the cover material brought together with or without adhesion. Usually the seam is implemented by adhesion, folding or interfitting but a mere overlapping of two edges is sufficient to constitute a seam.

WRAPPER

A species of flexible cover material in which the initial wrap is bent or folded about the contents as the first step in the encasement of the contents to make a package.
