GLASS CONTAINER Filed Jan. 2. 1951 gi gd.

. 1 I l r I I Gnu/nap.

Patented July '12, 1932 UNITED. STATES- PATENT OFFICE *canr. e. meanness, or nan'rmonn, MARYLAND, ASSIGNOR tro cane-toms GLASS CO., OF BALTIMORE, MARYLAND GLASS conmrm Applicatldn filed January 2, 1931. Serial lio. 508,249.

This invention relates to glass containers of that typeemploying screw caps.

glass containers are'formed in molds they are produced with protruding seams or minute beads where the mold members come together. Thus when a container has been formed with a threaded neck finish, these'protruding seams have appeared on the threads and cut into and mutilated screw caps formed of Balselite and like materials such as now generally used. This has interfered with the proper sealing action of the cap'engaging the thread. As a means for avoiding this objectionable feature it has been the practice to mold glass containers with jump threads. In other Words the threads are eliminated at the, seams so that there will be no portion of the glass protruding beyond the threads. This structure has not been entirely satisfactory, however, because it has weakened the neck portion and left portions of the threaded cap fully spaced from theneck finish.

It is an object of the present invention to combine the advantages of a continuous thread and a jump thread without having the disadvantages resulting from the forma tion of a protruding seam.

With the foregoing and other objects'in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, maybe made within the scope of what is claimed, without departing from the spirit of the invention.

. the protruding seam being exaggerated.-

Referring to the figures by characters of reference, 1 designates a container which can be of any desired configuration. The neck 2 of the container has a continuous thread 3 molded thereon but at those points where the protruding seam 4 extends across the thread, said thread is reduced in size as shown at 5 so thatthe protruding portion ofthe seam will not extend beyond continuations of the faces of those ortions of the thread which are not reduce Thus it will be seen that when a screw cap is placed in engagement with the threaded neck the seam will not engage and bite intothe cap. However the thread will have the advantages of both a continuous threadand a ump thread.

In practice it has been found possible to extend the reduced portion not more than -10 each side of the seam or joint. It has also been found that the main thread can .be made longer and thus provide more bearing surface for the screw cap than where a jump" thread is used, thereby insuring a better connection.

What is claimed is: 1

1. A glass container having a neck provided with a seam and a screw thread molded on the neck and extending therearound, that portion of the thread crossed by the seam being reduced in size to an extent not less than the height of'the seam. 2. A glass container having a continuous screw-threaded neck finish anda seam extending across the thread, those portions of the thread crossed by the seam being reduced to support all of the protrudin portions of the seam within the area de ned by the threads. 3. A glass container having a continuous thread on the neck portion thereof, there being a protruding seam on the neck portion and extending across the thread, said thread being so shaped as to prevent protrusion of the seam beyond the outermost surfaces of the thread. In testimony thatI claim the foregoing as CARL G. HILGENBERG.
