CONTAINER-TOP.

Specification of Letters Patent.

Application Ied May 8, 1915. Serial No. 26,719.

To all whom t may concern:

Be it known that I, O'r'ro ject of the King of Norway, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Container- Tops, of which the following is a specification.

My invention relates to that class of container or receptacle tops that are provided with a movable member having one ornmore openings or perforations adapted to be brought into and out of registry with an openingor openings inthe top proper for the purpose of permitting the contents to GOETZKE, a subescape or to seal the receptacleagainst the escape of its contents at the will ofthe Iao ' section through The invention relates more Iparticularly to a construction of top whereinthe movable member slides or moves in a rectilinear path and the object is to provide a simple, effective and cheap construction of top ca. pable of being used conveniently in the intended manner.

To these ends my invention consists in the construction of container or receptacle top more particularly hereinafter described and then specified inthe claims.

In the accompanying drawings Figure 1 is a side elevation of a form of top embodying my invention. Fig. 2 is a plan of the same. Fig. 3 is an end view. Fig. 4: is a longitudinal vertical section of the top. Fig. 5 is a perspective view of the top, Fig. 6 is a vertical cross-section thereof. Figs. 7 and 8 show in vertical cross-section modifications in the form ofthe sliding cap and head. Figs. 9 and 10 are longitudinal sections illustrating theapplication of a spring to the sliding cap. Fig. 11 is alongitudinal cross- `rone yend of the container top provided with a spring for the sliding c t which top `may be oval, circular,

receptacle,

or of other form that may be ap. cases, however, 1t is 1 indicates the top properfof the can or Figs. 7 and 8 in which case vention the perforations are indicated as being a line of perforations formed in the top or extremity of the head for coperation with a similar line of perforations in the sliding cap.

4 is the sliding member ofthe device and consists of a cap or shell superimposed on the head and guided thereon in a right line by means of its straight side flanges or skirts and is held in position upon the head by the crimping in of said skirts or side flanges on the line 6 where the side flanges engage the xrstraight sides of the neck and are thereby guided so that the cap maybe moved back and forth on the head to bring its line of perforations into and out of reglstr with the perforations in the top of said As will be observed by reference to the drawings, the ends of the c ap are closed in by the end portions or plates 7 which join the side flanges and complete the contour of the cap and serve not only the purpose of stifening said cap l, and preventing disen gagement of the side flanges with the guides formed on the head but likewise .serve as thumb-pieces for operation by the user in sliding the cap back .and forth upon the head. Furthermore, as will be seen, flanges are somewhat longer than the portion of head upon which the cap slides and the end portions of the flange thereby are enabled to operate as stops for the sliding movement andv to determine the extent of movement for bringing the holes in the top of the cap into registry with the holes in the top of the head or for limiting the reverse sliding movement of the cap when the receptacle is to be closed.

In the form of my invention illustrated in Fig. 1 the cap and the top of the head' are of curved form and the openings in both members -occupy a straight line. In some desirable to make the top of the head flat and the top of the cap also flat, as shown more particularly in a double line of perforations or'openings might be employed if desired. 'In some respects the form shown in Figs. 7` and Sis more desirable since the two members being flat, a more perfect seal is formed'.

in so forming the parts the side or flanges are crimped or compressed into the guides the cap will be held down upon the head by asprmg pressure which insures a continuous engagement of the ca and head' along the line of the perforation or perforations, thereby conducing to a more perfect closure. This end is accomplished by leaving a slightA space between' the sides of the cap vand the sides of the head as illustrated in the cross sections, so that the spring of the metal of the flange will operate to hold the top ofthe cap down upon the top of the head.

Fig. 8 illustrates another form of the invention in which the flange is crimped into a groove formed in the side of the neck to form the rectilinear guide for the cap.

By constructing the cap with the end portions of its flange or skirt separated from the ends of the head or portion of top upon Y which it slides as already described, I secure the advantage that ockets are provided for the reception of) blade or vother springs 8 located between the flange and head as illustrated in Figs. 9, 10 and l1 wherein the end flange'is shown as turned under at its bottom to hold the spring and prevent it from slipping out of the pocket.

As shown in Fig. 9, a spring may be provided at each end or in each pocket and the two springs coperate to center the cap with the perforations therein and in the head out of line so that the receptacle will be sealed.`

Pressure applied by the thumb to either end flange or plate obviously will bring the hole or holes into registry and allow the contents to escape, while upon release of pressure the cap will automatically resume a position cap in position tol seal the top.

properfor sealing the receptacle. -In Fig; 10v the cap is shown as provided with one spring only which serves to only hold the As will be understood, the 'members of the can top described are preferably made of sheet" metal throughout althoughI do not limit myself to the use of such material for all portions of the device. In case a spring is used it may be desirable to turn in the lower edge of the end flange or portion of the skirt to retain the spring in place.

By constructing theJ cap .as shown so that it engages with the head only on the top and at the bottom of the flanges or skirts as is the case whenv the space between the 4'sides of the flanges and the head is provided,

` the cap works with' greater freedom` and the liability to the lodgment of material between the surfaces of the cap and head 4which .exists particularly in those forms wherethe cap rotates on the head, is avoided. Any material,A moreover, that might tend to lodge is by my construction permitted to wrk out at the end of thel cap owing Tato the provision of the-"spaces on the sides and'betweenthe ends v and ends of the head.

By this construction I am enabled to manufacture can tops having a sliding cap, in an economical fashion and so that they will be free from the objections found to exist with the ordinary rotary top.

What I claim as my invention is l. In a container or receptacle top, the combination with a perforated head, of a perforated permanently attached sliding cap havin rectilinear depending side flanges guided upon the head and joined at both ends in end flanges completing the contour of the top', said side flanges being longer than the head and said end flanges joining them coperating with the head as stops for limiting the movement of the cap in both directions and determining by the action of one stop the extent of movement which will bring the holes of the cap and head into registry and by the action of the other stop limiting the reverse movement in closing the receptacle.

In a container or receptacle top,the combination with the perforated head, of a perforated permanently attachel sliding cap moving in a rectilinear path thereon, said cap having side flanges crimped upon and guided by rectilinear guides on the head and' being stiffened to prevent their disengagement from the head by end flanges at both ends coperating with the head to form means for limiting the movement of the cap in both ldirections as and for the purpose described.
