For d0

to frequent overflow, it is common, in practice, to be placed above the container with a cover in which is drilled a hole suitable for simply that a straw can be inserted therein. This usage is neither desirable nor practical for hot liquids, including coffee and tea, for a number of reasons including the fact that a straw

It has been suggested other container closures to overcome such difficulties and undesirable characteristics, but none of these closures from proved practical.Though it is known a number of related devices in the past, none of the known devices thus does combining multiple particular features on which the invention is based and which comprise a return means particular

sealed characteristics the closure. While the user account on the simple elasticity of the material in which is formed the closure for re-locating the sealing member, it will often recognise that after several uses, the memory of the resilient portion of the closure will not retained stablishe, so as to result in a reduced or poor sealing of the opening of the container itself. This setback particular can be, in other, overcome easily according to the invention.I0 proposed is, in effect, according to the invention, a self-sealing closure for a container comprising: a central face provided with a through slot or opening defined by overlapping edges, an edge or skirt extending from the periphery of the central face, said rim being provided with a nesting engagement means provided on the inner side of the border, as an integral part thereof, for engaging or nesting on a seat formed by an opening of a container, said means comprising a member forming part of the border of integrating the central face and DC

.By referring to Figure I in, we can see a closure II is provided with an opening or slot 20. The opening "" 20 has an arcuate shape and is perpendicular to the plane of the central area 15. In a preferred embodiment, the opening extends over slightly less than a semicircle and

closing II into two associated parts, a part movable i0 19 with an edge b and a fixed part 18 with an edge A. the opening 20 is formed by the edges a and b, said edges abutting against one another in abutting or come together when the closure is not attached to a container or cup i0. It should be noted, as appears in the description hereinafter, that this mutual arrangement of said edges transforms into a layout in which the edges a and b overlap to form a seal when the closure is secured

appliquêe

or on the container. Indeed, the overlap or cover is such that the edge b of the movable part is reduced below the boron concentrations with the fixed part. This arrangement is easily obtained by giving to the mouth of the closure a non-circular shape or performed in any other way which deviates from a round shape for said closure. This aspect of the invention can be better understood with reference to Figure I-, NAD which represents an outer dimension X of the closure 11 which intersects, in effect, the opening 20 and the outer dimension

approximate container that is slightly larger than the outer dimension passing through it at right angles to said X dimension. In practice and, only single example, dimension X could be, in the order of 7.7 cm, while dimension Y would then be of 7.6 cm. Thus the conformation of the mouth piece has a slight curve of an ellipse when this one is not

or attached thereto so that the edges and e is often mutually disposed in abutment. It will be appreciated that the closure is to be

on a container such that the X dimension to conform the size of the rim of the container to be easily placed above the latter, while dimension Y shorter requires a very light action of extension or stretching to reach the rim of the container and engage a suitable way on <

of O" pp thereof. The overall effect resulting generates a layout of mutual overlap of the edges a and b when!' plug is disposed on the container.Outside straddling relation pp mutually overlapping resulting from the slightly elliptical shape of the opening of the shutter, the invention provides, in combination, a mechanism.tensioning of a spring effect which maintains relatively constant over the structure of the closure, so that the edges a and b are held in the above mentioned fastening or sealing until sufficient force is applied to the movable part or 19.Referring to Figures 4 and 5, we can see the associated closing in the operating position to the container or the beaker or similarly shaped container often used in!' industry products to be transported. In

gênéral

, a container of this kind is made of plastic, paper, cardboard or the like, and it is provided with a flange or flared edge 16 provided at the periphery of the mouth end of the container.Referring to said Figure, we can see one embodiment of the closure II-specific TREs

placê

I0 on on the container, and, in particular, we will first consider Figure 2 which represents a first embodiment of the invention. The self-sealing closure member depicted in said fig. 12 comprises a rim adapted to fit on the rim of the container and provided with first and second members 13 and 14, as an integrated part of said border and respectively disposed on the inner surface of said edge 12. as shown in greater detail in Figure 6, said elements combine at substantially a member 23 for engagement with the container rim and extending along the inner portion of the edge of the occluder in being spaced uniformly from the top of the stationary part 18. member 23 for engaging the flange of the container assumes, when viewed in a direction perpendicular to the central face 15 of!' shutter-II, a conformation that is substantially circular or elliptical and wherein are the first and second members which are attached to the rim engaging the flange of the container and form a channel 22

disposê

axially for reception and slipping it onto the flange or flared edge 16 of the

ïécipient

10. In effect, the ends of two substantially semi-circular members, join ouchand W-I-L::: " defining an elliptical shape when the closure is not attached to the container, the contrary by defining a substantially circular shape when it is attached or applied to the container. Further, the flared edge or flange 16 is generally enclosed by the 23 member interlocking said flange securing a closing tightly sealed. Thus, as can be seen in the Figures, the first member is joined to the second member 13 14 which, as well as the first member, contributes to the appearance of the docking element on the ledge, which i0 extends over the peripheral portion of the inner face of the rim 12. also in this case, the members being provided with channel 22, said channel having itself substantially the shape of a U-shaped opening returned.As can be seen in Figure 2, the first member 14 is arranged in a first imaginary plane, said plane being parallel to a central face 15, while the second element 13 is arranged in a second imaginary

Dlan

, said second plane being inclined, and not parallel to the center side in this particular embodiment. Referring to Figure 2, we can see that this arrangement results in the formation of a structure of the border of the closure confectioneries like a letter L in Figure 3, which represents yet another embodiment of the invention comprising a first member 14 'and a second member 13' in this SAW elements are both inclined inwardly from the central face 15 'and assume, as a whole, more or less the form of a V. in this case also, as seen in Figure 3, the

premíer

member 14' is disposed in a first plane, said plane being slightly inclined from the central face confectioneries 15 ', while the second element 13' from plug disposed in a second plane, said second plane of this embodiment mutant is also inclined and not parallel to the central face. It is visible after these aspects that said planes intersect along a line which falls well on or forms a main rope that passes an axis or point of a line passing itself by the focal points of the circular or elliptical closed loop formed by the distinguished for interlocking with the flange of the container, and that the first and second imaginary planes intersect at subtending an acute angle. Said acute angle is represented by the angle in Figures 2 and 3. the acute angle thus formed is typically between 0.5 ° and 20° and, preferably, between 0.5 ° and 5°.The closure is provided with a slight recess or depression 24 well formed between said central face 15 and the stationary part 18. generally, the opening is accommodated in said recess, to the base thereof, and assumes an annular aspect. Although the recess can be only small, it serves as a bearing for the upper lip of the user to thereby facilitate!' normal absorption and comfortable of a liquid contained in the container. According to an additional feature, there may be used a small tongue or connecting means placed across the opening at or near its midpoint, to facilitate stacking of the containers.For use,

c'est

to say for the consumption of a product contained in the container, when a user places said container provided with the closure according to the invention, in a normal position, its lips and, in some cases, its nose come into direct contact with the movable part or central side so as to cause the movement of said part or face inwardly to release a consuming area. The contents of the container may then be freely absorbed or consumed by the user.When the user has completed its consumption, by removing its lips, it causes immediate feedback of the portion or side

çrécltée

sealed in its engaged position, by the restoring means described above.By turning the receptacle to the spilling or placing it on the side, there can be no chance output or projecting the content such as a liquid from said container, because the edges overlapping or overlapping, that the stationary part has supports and holds the movable portion b is in place, and that the movable part B is pushed up and held rigidly against the portion has through the biasing action constant proper to closure elements of the invention, when they are mounted on the rim of the

fìxés

or container as described above.According to the invention, the closure may be provided with one or more reinforcing ribs or lateral fins 17, in any quantity, which contribute to the structural stability of the closure. It should be mentioned that the self-sealing closure as disclosed has robust and durable for the use U-frequent -... - '+ :',: - ", .:.>: OE: O-
