Norton ABSTRACT: A straw puncturable dispensing opening which includes a thin sheet of material which is sealed to the outside surface of a surmounting closure of a liquid container around the dispensing opening thereby making possible an easy visible inspection of the condition of the seal.

1 serting a straw in the opening whichgis primarily intended 'and J adapted for pouring. out the contents; The"arrangements"*in most present liquid containers of the quart'pintorhalf pint size for opening and pouring out'the contentsis eithera pull tab which has an attached portion whichis pulled'out'leaving' a. hole, or a surmounting closure on thecontainer-whichis of the"' gable top type and which houses a pouring lip which is un-"' folded out to pour out therliquid contentsrBoth of thesejog known arrangements necessitate a pulling and holding by'the fingers in the immediate vicinity of theopening to ready the container for pouring. Anymotionof fingers perhaps of soiled hands in the immediate vicinity of theopeningis undesirable from the sanitation aspect since -particles'therefrom maybe passed through .the opening and vtherelriy contaminate-1hriiquid contents of the containenFrom a sanitary viewpoint in e another. respect,the above-describedarrangementsleave a lot' to be desired when used with a straw;'since theopening'area'of the above openings for pouringtare much=largenthanthe-cross sectional area of a straw, so that after-these: containers are" opened, much space is left aroundthe-inserted straw-through which airborne contaminants'mayenter the container and liquid thereinsThe liquid containersof =the"'above'types*for*-' orange juice, milk, etcr'which arefound' in all cafeteria and? food stores which are used for individual consumptionare ar ranged for pouring out the liquids therefrom whereas when'it is a requirement'that these containersgen'erally of the "pint or half-pint size) have means-therein permittingpassage: of a straw thereinto for withdrawing the contents therefrom; a sim pier and cheaper arrangementof the container ispossible".

The object of this invention is toprovide outlet means foraliquid container which is'adapted especially foruse'by a'straw for the withdrawal of liquids therefrom.

A further object of this-inventiorr'isto providea liquid con tainer adapted for use with a straw which is especially s'anitary since-not requiring a substantial ar'nount'of fingering or han-- dling around the opening area through which the straw=is passed or permitting entry of airborne 'contaminantsafteh opening and insertion of the straw.r-

It is yet another object of this invention to provide means=in- It a container which permits fast entry "of a straw therein'forthe withdrawal of liquid therefrom.

It is also anotherobject of this invention to' provide a simple,

inexpensive and easyto use,'arrangement in a container for passage of a straw into the container..-

In accordance with a preferredembodiment of the invention a container for-liquids is surmounted by closuremeanswhich closure means-has an aperture therein; The apertureis covered by a thin sheet of plasticlike materialwhichfi's pierceable' by a. straw. The periphery- 0f .the' thin sheet of plasticlike material'is sealedto thet'outside or top of the' cl'o sure means taught and in liquidtightrelationi" Other objects, features, applications and? advantages-50f the present invention will becomemanifest" to those vcrsed' in thef art upon making reference to the'detaileddescriptionwhich followsand the accompanying sheetof drawings which show differentembodiments of the presenuinventio'n. 1

When it has been decided as to what kind of straw is going to be used then the diameter of the aperture 4 is made larger than the diameter of the aperture to provide clearance for passing the straw through the aperture 4. A piece of material for a cover 5 is then selected which can be pierced readily by the straw without breaking or damaging the particular type of straw selected. An adhesive is selected which will attach and seal the cover 5 to the container wall 2.

Referring to FIG, 2 there is shown a boxlike container 16 having a flat top panel 17 and having no opening for removing liquid from the container 16 other than the simple aperture 18 with covering 19 which is pierced with a straw for the withdrawal of the liquid contents. The cover 19 is arranged over the aperture in the same manner as cover 5 was arranged over aperture 4 as was explained above in connection with the description of FIG. 1. Where straws are to be used exclusively with, for example, half-pint size or pint size containers containing a beverage such as milk or orange juice but-not soda or a beverage required to be kept under pressure, then a simple, inexpensive, paperboard type boxlike arrangement such as shown in H6. 2 may be used which has the cover 19 and aperture 18 therein through which a straw is pushed to withdraw the liquid contents thereof.' The narrow aperture 18 which'is only slightly larger than the straw passed therethrough does not permit the contents to come in contact with the outside air which might otherwise carry and pass contaminants to the liquid contents in the container.

Referring to FIG. 3 there is shown a milkshake container having a removable plastic cover 13. An aperture 14 and cover is arranged in a similar manner as the aperture 4 and cover 5 of the container 1 already discussed in connection with H6. 1. The aperture 14 may be larger than the aperture 4 since for milkshakes a larger straw is used and such straw will of course have to pass through the aperture 14.

Extra covers 5', l9, 15' with adhesive backing may be provided for temporarily rescaling the containers described if 'pierceable by a straw, the periphery of said thin sheet of material extending beyond the periphery of said aperture and being sealed to the outside surface of said closure means, and including a further sheet of material for resealing said container after piercingof said thin sheet of material, said further sheet of material having an adhesive backing thereon, said further sheet of material also pierceable by a straw. 1

2. A tubular container for liquids which is surmounted by closure means, said closure means having an aperture therein, said aperture being covered by a thin sheet of material 'pierceable by a straw, the periphery'of said thin sheet of material extending beyond the periphery of said aperture and being sealed to theoutside surface of said closure means, and wherein said aperture is slightly larger in cross section than said straw which is used to pierce said thin sheet of material,

said thin sheet of material being sealed to the outside surface of said closure means in liquidtight relation and so that said thin sheet of material is maintained taught across said aperture, said tubular container being rectangular in cross section and having four sidewall panels, said closure means being. a gable top closure housing a pouring lip including front and rear roof closure panels extending upwardly towards each' other from opposite, sidewall panels of said tubular container,

said aperture being located approximately in the center of one of said roof closure panels.
