3 Claims. (01. 215-43) l This invention relates to an improvement. in closures, particularly for bottles, jars, or other containers ofthe type adaptedto be removably attached thereto as by screw threads or other means of fastening a closure on'the container.
It has been proposed heretofore to construct closures with parts thereof of non-metallic material, such as paper, cardboard or the like, but such materials have required reenforcing with metal parts, either by'a metal hood over the outside thereof or a, metal ring inside the wall of the closure, to obtain the necessary strength and rigidity and to provide for the secure fastening of the closure on the container. I
It has been proposed also to form closures entirely of such non-metallicmaterials as plastic resins which contain phenolic compounds, but such materials are critical during the present war emergency and not readily available for the manufacture of closures for containers. The metals, such as tin and steel, used heretofore for the reenforcing of paper or other closures, are also critical materials not readily available for this purpose. I
The object of this invention is to construct the closure entirely of non-critical material, such as paper or the like, while at the same time effecting a secure rigid structure capable of being fastened tightly on a container, for removal therefrom, so as to seal the contents of the container effectively, and which closure is durable, inexpensive to manufacture, is of light weight, and lends itself to decoration or ornamentation in an effective manner. I
This closure is formed preferably both with a side wall and guide ring formed of paper or other thin non-metallic material that may be wound in multiple layers, with the upper edge of the side Wall turned inward and supporting a top disc thereon, while a liner has its periphery received between the inturned portion of the side Wall and the upper edge of the guide ring when it is securely held in place thereby and presents a neat appearance at the inner side ofthe closure.
The guide ring is formed by winding a thin strip of non-metallic material, such as paper, into a multiplicity of layers to provide the desired thickness, and by adhesive or otherwise securing the layers together. The guide ring is wound up of rigid form which will add strength to the closure and provide a detachable connection for the container which enables the closure to be applied thereto repeatedly, if desired.
The invention is illustrated in a preferred em- Mass, a corpobodiment; together-with modifications thereof, in
the accompanying drawin in'which;
Fig. 1 is a vertical sectional view through a closure embodying this invention; I I
Fig, 2 is a bottom plan view thereof;
Fig. 3 is a detail cross section through a mod ified form thereof; and
Fig. 4 is a similar view through astill further modified form thereof; r
The invention is shown as applied to the sealing of containers, such as glass bottles, jars or the like, of the character designated generally at C, and having a neck Ct at th open end thereof which is externally screw-threaded to receive a closure thereon that seals the inletand outlet for the container. I
The closure embodying the present invention is preferably constructed of paper or like nonmetallic material throughout, sufficient rigidity being provided by building up portions of the closure by means of laminations which are adhesively secured together to form a rigid unitary structure. The several laminations are exaggerated considerably in the drawing for clearness of illustration, it bein evident that in an actual construction, many more laminations will be used than are shown in the drawing, and of materiallythinner composite structure.
The closure is constructedof a top or--cover discil, which may be formed of cardboard, or I laminated pa'perfas described, of sufficient' thickand'is in the :form of a circular disc.
Extending about the peripher'y of the top disc I isa sidewallz formed of tubing of. multiple layers wound in spiral or convolute form; with the layers adhesively secured together so as to form a rigid wall structure for the closure. The upper edge of the side wall 2 is turned inward at 3 sufliciently far to overlap the upper edge of the neck CI of the container. This inturned portion 3 on the side wall 2 may be formed by spinning over the edge of the tubing, or pressing it inward, or in other suitable manner. The upper surface of the inturned portion 3 is adhesively or otherwise secured to the underface of the top disc I at the outer edge portion thereof.
Secured at the inner side of the wall 2 is a guide ring 4 of less vertical height than said wall 2, and havingthe upper edge thereof spaced downward from the inturned flange portion 3 to receive therebetween the periphery of a liner 5,
peripheral edge of the liner 5, clamped between the upper edge of the guide ring 4 and the in: turned flange 3, not only tends to hold the liner in place,'in addition to the adhesive attachment thereof to the top disc I, butalso'presents a-n'eatappearance to the inside of the closure by concealing the peripheral edge of the. liner.
The guide ring 4, as statedis formed of mu'l tiple convolutions which are wound one upojnranother and 'adhesively secured together. A thread I is formed on the guide .ring to interfit with the threadedlneck portion of the container; The guide ring 4 maybe secured to the side wall 2 by adhesiveor inany other suitable manner, andthe relative thickness .of these parts may be varied so long as they coact to form a rigidandsecure side wallstructure which has provision for detachably fastening the closure on the container. I I
desired, the side wall structure .may be enclosed within a decorating strip shown at 8 in 'Fig, 3 of thin paper or the like, and a similar decorating sheet 9 provided on the top disc I. Theseare not required where the decorations are applied .directly to the side wall and top disc, 7
or where no decoration is required.
As illustrated in Fig. 4, the side wall 2 is turned inward'at l9, if desired, over the lower edge of the guide ring i. for greater strength or decorating purposes.
It will be evident ,thateach part'of the closure maybe firmly attached to the adjoining part or parts with adhesive or other suitable binding material, so as tov resultin a secure and rigid structure. This substantial closure .is made entirely of paper or other inexpensive non-.critical material, andis capable of being manufactured at a much lower cost than has been possible here,- tofore. The construction issuch that thekclosure operates correctly onfastworkinglcapping equipment with .no change .in the structure thereof, Itmaybe used Wherever desired for the effective sealing of containers of .difierent types,
