2 Claims.
This invention relates to slip covers for fibrous containers of the type that are secured to the open end of the container by frictional contact with the outer wall of the container.
a The general object of the invention is a. slip cover provided with means readily operable to permit the slip cover to be quickly and conveniently removed from the container.
The fibrous container comprehended by this lo application is usually formed of a paper material, and the use of such containers has become universal, particularly, in connection with the sale of merchandise from retail stores, where the merchandise is transferred in bulk state tothe l5 container by hand, as for example, these containers are used in soda fountainsk for hot and cold liquids, and ice-cream, and the like.
Slip covers for such containers usually comprise a disk provided with a depending annular flange. 'I'he disk portion rests upon and forms a closure for the open end of the container, and the depending flange nts snugly around the outer wall of the container adjacent the open end thereof. Usually no specific fastening means is used to secure the cover to the container, it being held on the container solely by the friction between the depending flange portion of the slip cover and the side wall of the container. Accordingly, it is necessary to form the depending 30. flange portion of the slip cover, or at least a portion thereof, of such dimensions, or of such diameter, that it fits snugly on the open end of the container. OtherwiseVa sufliciently tight .seal will not be established between the slip cover and the container. On account of the necessarily tight fit between the slip cover and the container, two problems are presented. First, pushlng the slip cover onto the container andsecond, removlngthe slip cover from the container. )This invention has only to do with the second problem.
This problem, that is, the removal of the slip cover, exists particularly when the container is used for merchandise having gummy, or sticky, qualities, such as ice-cream, and also in connection with the use of the container for hot drinks. After the hotliquid cools, a considerable vacuum is created in the top of the container. On account of this, and together with the fact that the cover is originally of a tight fit, a considerable i0 Dull must be exerted to remove the cover. This often resultsin spilling the contents-of the container, or otherwise mutilating the cover, so that it can not be conveniently put back onto the container.
,5 The invention consists in the novel featuresV and in the combinations and constructions hereinafter set forth and claimed.
In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in.- all 5 the views.
Figure 1 is a fragmentary, side elevation of the slip cover and -contiguous portion of the container, partially in section.
Figure 2 is a fragmentary, sectional view taken 10 on line 2 2, Figure 1.
Figure 3 is a fragmentary, side elevation of a slip cover and contiguous portion of the container showing a modification of the invention.
Figure 4 is a fragmentary, sectional View taken l5 on line 4 4, Figure 3.
Figure 5 is a fragmentary, side elevation of a slip cover and contiguous portion of the container in section showing a modification of the structure shown in Figure 1. 20
Figure 6 is a fragmentary, sectional view taken on line 6 6, Figure 5.
The side wall I0 of the cylindrical container is usually formed of one or more layers of paper material.
II designates the disk portion of the slip cover which, as here shown, is provided with an upstanding annular flange I2.'y The disk II is secured to a depending annular flange portion I3 in any suitable manner, as by crimping of 30 the adjacent portions of the flanges I2, I3, as at I4. Usually, the slip cover is so formed that the internal diameter of the flange I3 is slightly less than the outside diameter of the container wall I Il. The slip cover is placed upon the open end ofthe container by pushing the flange I3 axially of the container and over the outer upper portion of' the wall I0.
Referring to Figures 1 and 2, the flange I3 is formed with a flap I5 defined by the upwardly 40 extending cuts or incisions I 6, and horizontal cut I 'I. The flap may be of any desired shape, but preferably the top cut I1 is located a short distance below the disk I I, and extends circumferentially of ythe flange I3, as indicated in Figure 2. The portion 2U, above the tab I5, provides a continuous sealing surface against the upper portion of the wall I0 of the container.
The incisions I 6 and II are preferably cut at an angle to the surface of the flange I3, as indicated 504 at 2 I, Figure 2, the incisions being cut at an angle so as to resist outward movement of the flap I5 beyond the peripheral surface of the flange I3.
Inl removing the slip cover from the container, the ap I5 is pressed inwardly by the thumb or A55 nger, as indicated in Figure 2, which in turn presses the contiguous portion of the side wall II) inwardly in spaced relation relative to the flange I 3, or the portion 20 thereof, permitting air to `enter the upper portion of the container to relieve the vacuum, -when the container has been filled with a hot liquid, and also reducing the friction between the container wall I and the iiange I3 of the slip cover. The notch produced in the flange I3 by the inward movement of the flap I5 forms a-convenient recess for the thumb, or nger nail, and thus provides a better grip with which to remove the slip cover.
In Figures 3 and 4, the ange-I3 is provided with an incision or cut 22 extending circumferentially of the fiange. The incision 22 is preferably spaced about the same distance from the disk portion II as is the incision Il deiining the top of the iiap I5 but of comparatively greater length to permit that portion 23 of the ange I3 immediately below the incision 22 to be pressed inwardly without tearing, or mutilating, the flange I3.
As shown in Figure 4, the portion 23 of the slip cover, immediately below and centrally of the incision 22, is pressed inwardly producing substantially the same eiect as that obtained by operation of the flap I5. It will be observed that in both instances the slip cover may be easily replaced on the container as no substantial damage is done to the flange I3 during the removal of the cover. Also, the incisions permit convenient escapement of the air from the container which results in an easier application of the cover to the container.'
In instances where the slip cover becomes xed, or set, on the container, as where the ange I 3,
`or upper portion of the container, becomes moist over a period of time, or in instances where it is not desired to replace the slip cover after it has been removed, the flap I5 may be provided with a pull tab 25, as shown in Figures 5 and 6. The pull tab 25 may be secured to the ap I5 by any suitable means such as a staple 26. With this structure, the slip cover is removed by pulling outwardly and then downwardly on the tab 25, which action swings the upper portion of the ap I5 outwardly and then severs the ange I3 immediately below the ap I5, thereby permitting ready removal of the slip cover.
What I claim is:
1. A slipcover for brous containers comprising a disk portion, a depending annular flange secured to the disk portion and arranged to snugly t the upper end of the container, an incision extending through the ange of the cover, the incision being arranged between the bottom of the disk portion and the lower edge of the ange, and being formed at an angle relative to the peripheral surface of the flange so as to resist outward movement of the ange below the incision beyond the peripheral surface ofthe portion of the iiange above the incision.
2. A slip cover for brous containers including a disk portion, a depending annular flange portion, a plurality of incisions extending through said flange and defining a hinged flap portion, said flap being provided with a pull tab.
