I following is a specification.
This invention relates to the manufacture of rubber water bottles or bags, or vessels of a similar kind, and it has for its object to provide an improved process or method of making such bottles in such manner that they shall be practically seamless. For many reasons it is desirable to avoid seams in such articles, but difficulty has been ex perienced in providing a method of making such a bottle which will permit the withdrawal of the core or mandrel, while preserving a regular or symmetrical shape of the finished article.
The present invention provides a method whereby a seamless bottle can be made, of a graceful and symmetrical shape, and with desirable reinforcement at the neck and shoulders df'the bottle. The invention also provides an improved manner of attaching or placing the metal thimble in the neck.
In the accompanying drawings, Figure 1 is a front elevation showing the bottle or blank in its first condition. Fig. 2 is a similar view, showing the slot or opening through which the core is removed. Fig. 3 is a view of the finished bottle, partly broken away showing the thimble applied.
Primarily, the body portion 6, the neck portion 7, the funnel portion 8, and the tabs 9 are molded in one piece, in a suitable mold, and over a suitable core or mandrel, corrugations 10 being formed on the inside of the neck portion.
In order to permit the core to be withdrawn, the neck and funnel portions of the blank are made in the form of two separate flaps which are united or continuous at their lower or inner ends with the opposite sides of the body, but which are free or disconnected'from each other above or beyond a slit or opening extending across the top of the bottle at the points 11 at the shoulder of the bottle. In other words, instead of making'the neck and funnel portions continu'ous and circular, they are split or left Will open at the ed es, down to the points l1, as illustrated in ig. 2, thereby producing a slit or opening at the top of the'bottle of sufficient length to permit the withdrawal of the core through said opening by stretching the body at said opening and stripping the bottle ofi of the core. It should also be stated that at the time the blank or body is made, as above indicated, each of the neck and funnel halves or parts 7 and 8 is provided along each edge with an extension or flange indicated at 12,; also, each shoulder of the body is provided with a flange 13 ex tending to the slit 11, 'for a purpose to be hereinafter described. The mold in which the blank is made as above described is suitably constructed for the above purpose, and the resulting blank is seamless and is closed at all points except the elongated opening below the neck.
After the removal of the blank from the mold and from the core the metal thimble or neck piece is applied. vThis is done by placing said thimble, which is indicated at 14, between the neck flaps 7, rubber gum or cement being first applied around the edges 12, as well as around the thimble and in the corrugations 10, the thimble being corrugated accordingly to engage therewith. The neck parts being then closed against the thimble, the flanges or edges 12 are lapped and pinched or worked together, by hand, to form the complete tube or funnel and to close the side openings or joints, thereby completing and forming the funnel, the neck around the thimble, and the portions at the base of the neck down to the points 11. It is then necessary to place the article in a suitable vulcanizing mold for the purpose of vulcanizing the raw gum and cement used for the purpose of fasteningthe top flaps together, as explained above. When inserted in such a mold or press and suitable heat applied the joints are cured and united, making a practically one piece bottle. The flanges 13, on the shoulders of the bottle, are used in this vulcanizing step for the purpose of being gripped by the vulcanizer parts while the vulcanizing operation is prohold the bottle in-the' vulcanizer while the joints are being cured. After the parts are united and vulcanized as above described the flanges 13 are trimmed ofi smooth, and the complete bottle remains, as illustrated in t will be observed that in addition to providing aT'novel means for withdrawing the,c0re at the top of the bottle, the in' vention provides an improved manner ofplacing andsecuring the neck, thimble in position and for reinforcing the bottle at the-part where it particularly needs it, that is, at the funnel, the neck, and the base of the neck, such-reinforcement being provided by the lapped, cemented and vulcanized flanges 12 I What I claim as new is: ,1. The method of making a rubber bottle or similar vessel, comprising molding the body and neck portions over a core, the neck portion being formed in two side parts with an opening therebetween permitting Withdrawal of the core, and uniting the [edges of said parts, after removal of thecore, to
form the neck.
2. The method of making a rubber bottle or similar vessel, comprising molding the body and neck portionsover a core, the neck portions being formed as two flaps or parts with separated edges extendingto the shoulders of the bottle, withdrawing the core through the opening between said parts, and
then uniting said edges toform the neck.
3. The method of making a' rubber bottle' or similar vessel, comprising molding the body and neck in a single piece over a core, the neck portion being formed as two side flaps with extended flanges'at'the edges thereof, withdrawing the core through.the opening between said flaps, and then uniting the said flanges to form thene'ck.
flanges to form the neck and close the shoulder opening.
5. .The method of making a rubber bottle 7 or similar vessel, comprisingmolding the body' and neck portions over a core, formingthe-neck portion in two side parts withan a opening therebetween, Withdrawing the core through said opening, inserting a neck thimblebetween said side parts, and uniting and. vulcanizing the edges of said parts, to form the neck and hold the thimble in place.
6. The method of making a rubber bottle or similar vessel, comprising molding the body and neckportions over acore, forming the neck portion in two separate side flaps with flanges at the edges thereof and transverse slits in the shoulders at the base of said flaps, withdrawing the core through the opening provided by said flaps and slits, and then uniting the flanges and closing the slits' by cementing and vulcanizing""the edges.
