American Can Co. v. M. J. B. Co., 48 F.2d 144, 8 U.S.P.Q. (BNA) 432, 1931 U.S. App. LEXIS 4192 (9th Cir. 1931).

Opinion

WILBUR, Circuit Judge.

This is an action for the infringement of patent No. 1,586,277), issued by the United States to John M. Young, now owned by the appellant, covering a familiar type of tin can, a right cylinder, used as container for food products, such as coffee, butter, etc. The type of ean involved is one in which the cover is severed from the cylindrical body upon opening, by removing from the upper end of the outer cylindrical surface a tearing strip of familiar design. The object of the invention is to utilize the top portion of the can as a reelosure cover to be used after the ean is opened by removal of the tearing strip, the cover fitting tightly enough to form a closure that will protect the contents of the ean. The method of thus utilizing the top portion of the can for reeoverage in order to protect the contents of the can is common in the canning industry. The.contents are sometimes preserved by what is known as an •outside slip cover, fitting over the outer portion of the can at the top (a familiar example of this type of cover being the old-fashioned tin dinner-pail). In appellant’s patent the air-tight closure is effected by friction between a countersunk part of the top and a ring or bulge at the top of the can and on the face of its interior wall. When the top is forced down inside the can, this countersunk part of the top contacts with the bulge or ring on the inside of the ean. Claims contained in the appellant’s patent, issued May 25, 1926, known as the Young patent, deal with the latter form of can, in which the countersunk portion of the top, when removed and replaced for reeoverage, upon depression comes in contact with an inner ring or bulge formed on the inside of the ean, spoken of in the briefs as an inner fold, bend or bead.

In view of the fact that the argument narrows the alleged invention to a single element in this combination, we can largely confine our consideration to that element. Appellant’s claim is narrowed in the briefs to the single item of the offsetting of the annular depending ring or countersink in the top of the ean from the side of the can. to the exact distance that the inner ring, bend, or fold projects into the inside of the can, so that upon removal of the tearing strip the countersunk portion of the top slips inside [145]*145this inner ring, bend, or fold, with a snug fit, thus sealing the contents.

The accompanying diagram of vertical cross sections, one through a portion of appellant’s can, and the other through a portion of appellee’s can, which are substantially as set forth in the briefs of the par- ■ ties in connection with their respective contentions, illustrate the point thus advanced by the appellant:

We have indicated in cross-hatching, and have marked “X” on each diagram, the portion of the top of ean body, in each of the two cans, which appellant claims is covered by the Young patent.

We restate the above proposition in the language of the appellant:

“The thing that was not known or old was the insetting or offsetting of the bung or internal reclosure from the seam by the thickness of the fold or bend so that the material of the can body part which contained the score lines may extend down from the seam on the outside of the fold in a single cylindrical plane to the bottom of the fold or bend itself. The construction of the ean beneath the fold or bend is, we submit, unimportant to the consideration of the claims because the structure in which the invention is embodied is located wholly above this portion of the ean body.”

In view of the claim that the shoulder “X” of the appellee’s can infringes the offset “X” of the appellant’s patent, it should be stated that the basis of this contention is the assumption that the 3-ply portion of the appellee’s can is the equivalent of the internal fold or bend of the appellant’s can, which is marked 18 on the above drawing. It is significant that when the application for appellant’s patent was pending before the Patent Office, the Examiner in the Patent Office called the attention of the applicant to the similarity between his method of reclosure and that involved in the Ginzler patent (British, 1910). A diagram of a vertical cross section, of the Ginzler.can is here shown:

It will be observed that in the Ginzler can the inner portion of the cap or cover contacts with an interior bend or fold in the side of the ean. The original claims presented by the applicant were rejected by the patent Examiner for lack of novelty over the Ginzler. Attention was also called by the Examiner to a prior French patent to Delpeut and a British patent to Spindler. Thereupon the claims of the Young application were amended to read as they appear in the patent in suit. The written amendments were presented to the Patent Office with the accompanying statement on behalf of the applicant that the patents referred to had been carefully examined, and that:

“In the Ginzler patent there is an upward bend, but it does not extend inward towards the middle of the ean, and the upper and lower parts of the can wall have to be out of line with each other to accommodate such a fold. This fold lies parallel with and against the inner face of the can wall and has not the yielding and gripping features of my bend 18. My claims distinguish very clearly from a construction like that in the Ginzler patent. It will be noticed also that in this patent there is no preformed (delineated by score lines) tearing strip but a rude and rough tear is made through the material of the can wall by a stiff internal tearing element, so that this can is entirely unsuitable to provide a replaceable cover.
“In the Spindler and Delpeut patents a replaceable cover may be formed, but it is an outside slip cover.
“I believe that I am the first to provide a can body with an inwardly extending bend, integral with the body, and with a plug closure to fit within said bend and similarly [146]*146offset inwards from the double seam of the cover and from the can wall.”

No further objections being raised in the Patent Office, the patent in suit was issued to John M. Young,- assignor of appellant.

It thus appears that the appellant, in securing his patent, differentiated the inner ring or fold in his device from that in the Ginzler .patent, although in the Ginzler patent the folds extend inside the can, that is the .can bulges inwardly at the point of the fold; whereas, in the appellee’s can the side of the can is vertical in its cross section from the bottom of the can to the upper edge of the collar or band which is produced on the outside of the can at its upper end by an outward double folding of the metal blank or sheet from which the can is formed.

It is well settled that, where an applicant whose claim is rejected on reference to a prior patent, without objection or appeal, voluntarily restricts himself by an amendment of his claim to a specific structure, “having thus narrowed his claim * * * in order to obtain a patent the patentee may not by construction, or by resort to the doctrine of equivalents, give to the claim the larger scope which it might have had without the amendments, which amount to a disclaimer.” Weber Elec.
