United States Patent O ce 3,119,543 NECK SECUREMENT FR CONTAENERS .lames H. Walker, 2655 Mait Ave., Los Angeles 22, Cali. Filed Aug. 28, 1961, Ser. No. 134,30) 7 Claims. (Cl. 229-14) This invention relates to containers and more especially to containers for liquid products for use in the home such as milk, fruit juices and other drinks, also liquids used for cleaning or for any purpose.

Container users at the present time are endeavoring to turn away from glass and metallic containers for liquids and a number of improved containers have been developed. One of such for-ms of improved containers is the well-known milk bottle type which is made of paperboard or fiberboard with complete inner and outer coatings of parain or wax. Such containers frequently have dispensing spouts or openings initially closed by Iflaps or other formations which, after once being opened, cannot be readily and effectively closed for dispensing initially unused portions of the contained liquid. Furthermore, such containers are generally rigid in form and require excessive storage space prior to the time they are lled with the contained liquid. There has been a long-felt want in the `art for a simple container Vfor liquids made of lightweight, inexpensive material and generally of the carton type in initially collapsed condition in order that handling and storage can be effected and requiring only a minimum of space.

Itis, therefore, the general purpose and objective of this invention to provide an improved container for liquids in the general form of a flat envelope having a semi-rigid neck formation that can be extended through the top ap of an outer box-like container of the general carton form.

Another object of the invention is to provide an improved neck securement for =a ilexible body container which is insertible in the relatively stiff body carton.

A further object of the invention is to provide a neck securement, as in the previous object, wherein the container neck is provided with a screw type cap which can be removed and be replaced with the effectiveness of a bottle type of cap. l

Another object of the invention is to provide a novel two-part container for liquids having a reusable screw type cover and wherein the parts are initially formed substantially flat for convenience in handling and storage prior to illing with liquid.

Other objects and advantages of the invention will appear and be brought out more fully in the following specication, reference being had to the -accompanying drawing wherein:

FIGURE 1 is a perspective view of a container embodying the present invention.

FIGURE Z is a top plan view of the same.

FIGURE 3 is a sectional view taken on line 3 3 of FIGURE 2.

FIGURE 4 is a partial sectional View taken along the line 4 4 of FIGURE 2.

FGURE 5 is a partial perspective view of the liner part of the container showing the neck securement features of the invention.

Referring more particularly to the drawing, the invention is illustrated in connection with a container unit having two parts, .10 and 11 respectively. Part 111 is a carton generally of conventional type and made of paperboard, lberboard or the equivalent having a front wall 12, rear wall 13 and a pair of side walls 14. The front and rear walls 12 and 13 have overlapping flaps 1S which are secured together to form the bottom of part 10, and front wall 12 has a top flap 16. Rear wall 13 has a narrow 3,119,543 Patented Jan. 28, 1964 top flap 17 which overlies and is secured to the free edge of top llap 16.

Top Hap 16 is formed with a circular opening and the edge portion of the flap adjacent the opening is radially slotted as indicated at 18 to form a plurality of tongues or tabs 20 which are deformable outwardly or upwardly on the neck of the container, part 11, when it is inserted through the top of the opening. Part 11, which comprises a liner for part 10, is formed of a pair of flat sheets 21 and 22 secured .together along their marginal edges 23 by cementing or a heat seal process, the sheets being made of a waxed paper or of Plio-lm, cellophane or equivalent plastic material. It will be understood that sheets 21 and 22 will be so formed and dimensioned that when lled with the desired liquid the walls will fill out or expand to positions adjacent the front, rear and side walls 12, `13 and 14 respectively.

At a suitable and selected position, preferably adjacent one of the shorter edges of part 11, a neck 2liis secured to one of the sheets, such as 21. Neck 2.4 has a flared skirt portion 2S, and a radial ange 26 extends outwardly from skirt 25. An annular bead 27 is formed on neck 24 .at the juncture of skirt 25 and four radial ears or ribs 2S are formed on the skirt 25, preferably in quadrature arrangement, as shown. Neck 24 has external screw threads 29 for the replaceable attachment of a cap 30. If desired, the neck 24 may be provided with a membrane or other seal closure 31 for the end of the neck to protect the contents of the inner container part 11 after it is so lled. The neck 2.4 is preferably made of a semirigid thermoplastic material and flange 26 thereof can sealably be attached to sheet 21 around an opening suitably formed therein.

In the assembly of the carton unit, the outer part 10 wi-ll be expanded from a collapsed condition and the end aps 15 or 16 and 17 sealed together. The inner part 11 is then inserted in the part lll and neck 2.4 passed through the opening in top flap 16. This movement will deflect tabs 20 a sufficient amount to permit threads 29 and llange 27 to pass through the opening, however, the tabs will spring back and underlie flange 27 whereby the inner part 11 will be supported in part from top flaps 16. As can be seen in FlGURES l and 2. the diametrically opposite radial ears or ribs 28 will extend into the spaces between adjacent pairs of tabs 211 and thereby provide an anchorage for the part 11 when the cap 30 is being screwed on or 0E.

It will be understood that the foregoing description is illustrative of rather than restrictive of the invention and that changes `and modifications may be made without departing from the spirit and scope of the -subjoined claims.

What is claimed is:

A neck securement for containers comprising in combination, a container including a top ap having an opening formed with a plurality of tabs, and a closed envelope receivable in the container having a threaded neck formed with an annular bead and an axial rib, and extending through said opening whereby said neck is supported on said top ilap with said tabs under said bead and with said rib between a pair of said tabs to hold the neck when a cap is screwed onto it.

2. A neck securement for containers comprising in combination, a container including a top flap having an opening formed with a plurality of tabs extending radially and inwardly, and a closed envelope receivable in the container having a threaded neck formed with an annular bead and at least one axial rib and extending through said opening whereby said neck is supported on said top flap with said tabs under said -bead and with said rib between a pair of said tabs to hold the neck when a cap is screwed onto it.
