Opinion

ALMOND, Judge.

This is an appeal from the decision of the Patent Office Board of Appeals, adhered to upon reconsideration, affirming the examiner’s rejection of claims 1-19, all of the claims in appellants’ application entitled “Method of Blowing Engraved Appearing Bottles Without the Use of Engraved Molds and Molds for Same.” 1

In the forming of plastic bottles by expanding a plastic tube under internal pressure within a mold, it is apparently desirous at times to produce bottles having surface ornamentation or indicia having the appearance of engraving. In order to achieve this, appellants have provided a manner of quickly and economically modifying the smooth internal molding surface of a typical splithalf blow mold so that the mold is capable of forming an engraved-appearing surface on a bottle blown within the mold without permanently altering the molding surface itself. This conversion is accomplished by adhesively securing to the mold interior a flexible insert having the desired configuration. Thus, the insert can be stripped from the mold after molding.

The claims fall in three groups: (1) Claims 1, 10 and 19 to an insert per se; (2) claims 2-7 and 11-15 to a blow molding method, and (3) claims 8, 9, 16-18 to a modified mold. Representative are claims 1, 2 and 8 :

1. An insert for converting a mold having a smooth molding surface to produce articles having an engraved appearing surface, said insert including a plastice base and metallic surface layer on one face of said base, the surface of said metallic surface layer being configurated complementary to the desired molded surface, and a low pressure adhesive on the base remote from said metallic surface layer for securing the insert within a mold.
2. A method of blow molding an engraved appearing plastic bottle utilizing a two part mold specifically formed for the molding of a plastic bottle having a surface configuration divided by a mold parting line with at least one half of said mold having a normally smooth molding surface, comprising the steps of temporarily modifying said mold half smooth molding surface by releasably applying to said smooth molding surface remote from the edges of said mold a thin insert having a desired surface configuration, blow molding a bottle within said modified mold with said insert projecting into the outer surface of the bottle during the molding process to provide the desire engraved appearance, setting the plastic of the bottle within said modified mold, and stripping the blow molded bottle from said mold with said insert remaining in place and intact on said modified mold half.
8. A mold particularly adapted for the blow molding of plastic bottles comprising two mold halves with at least one of said mold halves having a smooth molding surface remote from the edges thereof, said mold being complete and capable of use in blow molding usable plastic bottles, and a removable insert overlying at least a part of said smooth molding surface and forming a part of the molding surfaces of said mold, said insert presenting a three dimensional molding surface to produce engraved appearing impressions in bottles blow molded in said mold.

Benson discloses imprinting inner tubes while vulcanize molding them. A transfer is temporarily secured to a mold section by means of a dab of rubber cement, while an exposed face of the transfer is provided with ink or bronze. When a tube is inflated within the mold, the transfer attaches to the tube and is removed from the mold upon removal of the tube. The transfer is then stripped from the tube leaving the printing thereon.

Lawson relates to molding articles from plastic materials and especially the branding or marking of rubber or other plastic articles as they are formed in a mold and has as an object interchangeability of design. Illustrating his invention by reference to vulcanizing inner tubes, the patentee states:

In order to brand the tube with identifying indicia it is customary to provide one or more of the mold members with either raised or sunk lettering to impress the tube. Where it is desired to provide different indicia on tubes of the same size, this would ordinarily require different molds. In order to obviate this difficulty, one of the mold parts 16 is formed with a dove tailed recess 22 extending from the parting of the members 15, 16, along a face of the member 16 and a removable branding plate 23, having on its back a dove-tailed key 24, adapted to slidably engage the recess, is provided to be detachably mounted in the mold.

Haines discloses blow molding hollow containers by extruding a plastic tube into a split-half mold, closing the mold about the tube and directing air into the tube to expand it within the mold. The mold interior may be provided with a recess into which is placed a printed plastic film which is fused to the expanded container upon contact or the recess may be omitted.

Graham discloses a molding apparatus for molding printing plaques in which letters are magnetically held on the molding surface while plastic material is poured thereon. After curing, the printing plaque is removed while the magnetically held elements remain fixed to the surface.

Frank discloses a method of mounting decorative indicia by means of a sheet having pressure-sensitive adhesives on opposite faces thereof. One of the cover strips is removed and metal particles are applied to the exposed adhesive layer. Thereafter the other cover strip is removed and the sheet is applied to the desired surface.

The examiner rejected claims 2-7 and 11-15 on the ground of res judicata based upon the prior board decision in appellants’ parent application. The examiner also rejected claims 1-19 on prior art under 35 U.S.C. § 103.

Prior to treating the examiner’s rejections and the board’s affirmance thereof, we turn to what appellants contend is the first issue involved in this appeal, viz., the jurisdictional propriety of the presence of claims 11-13, 15, 16 and 18 before the court for decision thereon. In his Answer, the examiner withdrew a *446 multiplicity rejection and for the first and only time rejected the above claims on prior art. It is appellants’ contention that, under the requirements of 35 U.S.C.
