CPC Definition - Subclass B29C

Last Updated Version: 2019.02
SHAPING OR JOINING OF PLASTICS; SHAPING OF MATERIAL IN A PLASTIC STATE, NOT OTHERWISE PROVIDED FOR; AFTER-TREATMENT OF THE SHAPED PRODUCTS, e.g. REPAIRING (making preforms B29B 11/00; making laminated products by combining previously unconnected layers which become one product whose layers will remain together B32B 37/00 - B32B 41/00)
Definition statement

This place covers:

Processes and apparatus for:

  • shaping or joining of plastics;
  • shaping of material in a plastic state when a specific material is not identified;
  • shaping of material in a plastic state, not otherwise provided for.

Products obtained by processes provided for in this subclass, as long as the products are characterised by said processes.

Relationships with other classification places

Subclass B29C is often connected with the following areas:

  • B29B, related to preparation or pre-treatment of the material to be shaped, making granules or preforms, beyond recovery of plastics or other constituents of waste material containing plastics;
  • B29D, related to processes and apparatus for the production of particular articles characterised by their global structure, e.g. flat, hollow, or tubular articles, by their structural features, e.g. provided with screw threads, corrugations, grooves or projections, or by their purpose, e.g. buttons, optical elements, tyres or footwear. Attention should be paid to B29 note (3), i.e. classification according to production of particular articles in subclass B29D is restricted to:
  • aspects which are characteristic for the production of a particular article, and not classifiable in subclass B29B or B29C;
  • combined operations for making the particular article which are not fully classifiable in subclass B29C;B29C;
  • B32B, related to layered products (products built-up of strata of flat or non-flat, e.g. cellular or honeycomb form) as well as methods or apparatus for making layered products;
  • C08J, related to chemical aspects or features for treating, compounding, working-up or recovery of macromolecular substances not covered by subclasses C08B, C08C, C08F, C08G or C08H;
  • C08K, related to the use of inorganic or non-macromolecular organic substances, or mixture thereof, as additives in composition of macromolecular compounds;
  • C08L, related to composition of organic macromolecular compounds, such as polysaccharides and derivate, rubbers and derivate, macromolecular compounds obtained by reactions involving or not carbon-to-carbon unsaturated bonds, natural macromolecular compounds and derivatives.

Special rules of classification

In this subclass, the following rules must be applied:

  • The working of plastics is, as far as possible, classified primarily according to the particular shaping technique used in this subclass;
  •  Combined operations for making a particular article which are not fully classifiable in this subclass must be classified in subclass B29D.

Products per se are not classified in this subclass. However, if a product is characterised by the way it is produced and not by its structure or composition, the production method should be classified in this subclass.In this subclass:

  • repairing of articles shaped or produced by using techniques covered by this subclass or subclass B29D is classified in group B29C 73/00;
  • component parts, details, accessories or auxiliary operations which are applicable to more than one moulding technique are classified in groups B29C 31/00 - B29C 37/00;
  • component parts, details, accessories or auxiliary operations which are only applicable or only of use for one specific shaping technique are classified only in the relevant subgroups of groups B29C 39/00 - B29C 71/00.

In this subclass, it is desirable to add the indexing codes of subclasses B29K and/or B29L.

Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:

A plastic

is a macromolecular compound or composition based on such a compound

In a plastic state

refers to a state in which the material is more or less easily deformable, locally or as a whole, by force in any direction, to assume and retain any desired shape.

Special rules of classification

Moulds specific for a single moulding technology are classified in that technology: e.g. moulds for injection moulding B29C 45/26, moulds for blow moulding B29C 49/48.

Since the classification scheme present in B29C 45/00 is much more detailed, for reasons of search efficiency, classification in B29C 45/00 is preferred above a classification in B29C 33/00 in the case that both classifications would be applicable.

Relationships with other classification places

The difference between B29C 45/14786 and resin transfer moulding (B29C 70/48) is the way of coating.

In the group B29C 45/14786, the fibrous insert is not completely impregnated but coated at only one side.

A process, whereby an insert of fibrous material is complete impregnated refers to resin transfer moulding, even if the process is done by injection moulding.

Relationships with other classification places

Concerning the preference of B29C 45/14827, it should be taken into account that this preference concerns either a double layered product where one layer is the transfer foil or a multilayered product, but were the invention concerns the use transfer foil as such (the identity of the other layers are not important for the invention).

Moulding processes, where the invention concerns the making of the multilayered inserts and where the fact that one of the layers can be removed is only disclosed on the level of additional information, is covered by the group B29C 45/14811.

Relationships with other classification places

The difference between injection compression moulding (B29C 45/561) and B29C 45/572 is typically that in injection compression moulding a movable mould half is used for shaping the material in the cavity, while in B29C 45/572 the already shaped material is pressed for compensating the volume change caused by the shrinkage. Pressurizing is typically done locally e.g. by pressurizing pins

It is further noted, that B29C 45/56 comprises a reference out, that B29C 45/572 takes precedence.

Special rules of classification

All material aspects, not only the moulding material as such, but also fillers, preformed parts of mould (die) composition has to be identified by allocating the appropriate Indexing Code of B29K. This also applies to moulding material properties, e.g. tear strength for identifying that extruded layers are easily torn apart is classified in B29K 2995/0081.

Extrusion techniques characterised by the material must be allocated a classification in B29C 48/0022.

All SHAPING CONDITIONS influencing the extrusion technique, e.g. extrusion in sterile or vacuum environments, the application of vibrations, must be identified by allocating the appropriate Indexing Code as provided in B29C 2791/004 and subgroups, as well the classification in B29C 48/14 or subgroups.

Cutting operations and printing operations must be identified by allocating the appropriate Indexing Code as provided in B29C 2793/00 and B29C 2795/00.

All ARTICLES must be identified by allocating the appropriate Indexing Codes as provided for by the subclass B29L, e.g. anchoring between layers in general, e.g. due to chemical treatment B29C 2045/1664, mechanical anchoring in general, e.g. layers gripping into each other B29C 37/0082.

COMBINATIONS of extrusion and other techniques corresponding to the subgroups of B29C 48/001 are classified in B29C 48/001 or one of its subgroups.

Orienting or stretching of extruded materials should be identified by allocation the Indexing Code B29K 2995/005 and B29K 2995/0046 or one of its subgroups.

The Indexing Codes B29C 2791/00 - B29C 2791/003 are generally not used in this group B29C 48/00.

All MEASURING and CONTROL aspects must receive the relevant code(s) in the B29C 2948/92 indexing scheme.

Special rules of classification

- For articles and materials, as much as possible additional classification by adding the Indexing Codes of B29K and B29L is recommended.

- If more then 4 different thermoplastic materials are described in the disclosure then the Indexing Code B29K 2101/12 should be allocated. In addition only up to 4 of the disclosed uncommon thermoplastic materials are classified (common thermoplastics for blow moulding are PET, PE, PP) by allocating the appropriate Indexing Code as provided in B29K 2001/00 - B29K 2101/00.

- Inventive and additional information disclosed in documents to be classified should be identified by allocation the appropriate classification codes of B29C 49/00 - B29C 49/78. In particular attention should be paid to the so called break down Indexing Codes, which are only present at additional information level, but should be allocated if disclosed in the document to be classified.

- If during blow moulding also vacuum is used, or only vacuum is used for deformation of the tubular parison then one or both of the following classification codes are additionally allocated: B29C 2791/006 and/or B29C 2791/007.

- making of balloon catheters by combined operations, e.g. an additional moulding technique to blow moulding is additionally classified in one of the sub groups A61M 25/1027

Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:

Preform or parison

A tubular object obtained by moulding substantially consisting of plastic material, which has to undergo an additional processing step, e.g. blow moulding, to obtain its final shape, examples are: tubes, extruded parisons, two parallel sheets which behave like tubular preforms, injection moulded tubular preforms normally with one end closed.

Blowing

using a pressurized blowing gas to deform the tubular preform or parison; but also applying a vacuum on one side of the tubular article, since the ambient pressure is deforming the tubular preform or parison.

Making preforms characterised by structure or composition

B29B 11/14

Special rules of classification

- The use of the indexing of preforms for blow-moulding bottles, using the coding scheme under B29B 2911/14, is obligatory when the structure of the preform differs from the conventional shape (meaning: one layer, open neck, flange, cylindrical body, closed semispherical end).

- If a preform is claimed and in the description it is mentioned that the preform would be suitable for blow moulding --> then the additional classification code B29C 49/0073 is allocated to this document and the document is additional classified in B29B 11/14.

- If a tubular reheated parison (meaning: has two open ends) is used during the blow moulding process then, the following Indexing Code should be allocated: B29K 2105/258

Special rules of classification

- For articles and materials, as much as possible additional classification by adding the Indexing Codes of B29K and B29L is recommended.

- If more then 4 different thermoplastic materials are described in the disclosure then the Indexing Code B29K 2101/12 should be allocated. In addition only up to 4 of the disclosed uncommon thermoplastic materials are classified (common thermoplastics for thermoforming are PET, PE, PP) by allocating the appropriate Indexing Code as provided in B29K 2001/00 - B29K 2101/00.
