vented by Lucius D. Richardson, and assigned to the assignee of the present invention.
BACKGROUND The invention pertains to packages of the type for dispensing a product contained therein.
Many varieties of dispensing packets are known. In some, opening has been provided through perforations, either in the flange or in the pocket or receptacle portion. Others anticipate tearing of the flange, removal of a cover, or pulling a tab. Each has certain drawbacks and an improved opening feature is desirable.
SUMMARY The present invention relates to dispensing packets and more particularly to such a packet having an improved opening feature.
A general object of the present invention is to provide a new and useful dispensing packet which can be easily opened.
Another object is to provide a dispensing packet which is initially imperforate to protect the contents but which has a unique opening feature for the dispensing thereof.

DESCRIPTION Reference is now made more particularly to the drawings which, by way of example, illustrate several embodiments which represent the best presently known mode of carrying out the invention. Similar reference characters indicate the same parts throughout the several views.
In the embodiments illustrated, the dispensing packet is advantageously made of a sheet of synthetic resin material, generally designated 30 and a sheet of covering material 31 which may be transparent. First and second imperforate recessed pockets 32 and 34 are provided in a central portion of the sheet 30. The recessed pockets may take any desired shape and may be of the same size or different sizes. Both pockets may be utilized for holding a material to be dispensed, as is contemplated in the embodiment of FIG. 1, or one of the pockets may be principally for holding the material to be dispensed, as contemplated in FIG. 9. At least one imperforate recessed neck 36 intercommunicates the pockets. As shown, the pockets and the neck are initially open at the top side thereof but closed by the cover 31. An outwardly extending peripheral flange 38 surrounds the pockets and the neck at the open side thereof. In accordance with the present invention, the cover material 31 is secured or sealed to the peripheral flange 38 to secure the product to be dispensed within the packet.
Pocket 32 has a bottom 42 spaced from the flange 38. Similarly, pocket 34 has a bottom 44 spaced from the flange. The neck 36 has a generally semihourglass shape provided by a reduced portion with a well-defined juncture 46 intermediate the pockets and at a level above the pocket bottoms. The well-defined juncture 46 provides an internal throat of a generally U-shaped cross section. In the embodiments illustrated, the cross section is substantially semicircular, but other shapes may be used. The neck 36 tapers outwardly in opposite directions from the throat. For this purpose, the neck has bottom wall portions 47 and 48 extending toward bottom walls 42 and 44, respectively. The well-defined juncture or throat defines a plane which, when extended through the flange 38 provides an imaginary line 48 passing between opposite edges of the flange without passing through the pockets 32 and 34 (see FIGS. 2, 9 and 12). The pockets 32 and 34 are swingable about said line 48 to rupture the neck 36 at the throat 46 for dispensing the product through the resulting opening in the manner illustrated in FIGS. 6, 7, 14 and 15. The manually applied forces are indicated by arrows in FIG. 5. As a result of the particular shape of the throat, the packet ruptures at the throat when flexed or swung about the line 48. Swinging about the line causes a downward component of force at the juncture 46 while the side walls of the throat restrain the juncture against this component. This component, however, keeps the throat from collapsing during the swinging movement. Simultaneously, the horizontal components of force put the neck in tension with the overall result that the neck ruptures at the welldefined juncture. At this point, it should be observed that an ordinary tube collapses when swung in the manner of the present invention. Similarly, a relative planar bottom does not rupture at a preselected neck as in the present invention.
In the embodiment of FIGS. 1-8, another neck 37 also intercommunicates the pockets 32 and 34. In this embodiment, the well-defined junctures' of the necks are preferably coplanar for the opening operation. Intermediate the two necks is formed an island or plateau 52 which has an upper surface at the level of the peripheral flange. Preferably, the cover member 31 is also sealed to this upper surface to assure dispensing only through the necks 36 and 37. The swingline 48 extends through the island and the island provides a convenient point for the application of manual pressure for the swinging operation, as shown in FIGS. 6 and 7. By pressing on the island, as by the thumb, force is applied midway between the necks 36 and 37, and the necks are simultaneously ruptured by the swinging action.
After opening, the contents may be dispensed through the resulting openings and the packet is easily placed to a non-dispensing position (FIG. 8) by resting it on opposite ends of the flange 38. For this purpose, the packet of FIGS. 1-8 is generally rectangular and the swingline 48 is about midway between the ends of the packet. It can be seen that the first and second pockets 32 and 34 are on opposite sides of the swingline and the island is generally midway bet-ween the sides of the packet. In this manner, the packet of the embodiment of FIGS. l8 is generally symmetrical about the swingline 48 and about its longitudinal axis.
In the embodiment of FIGS. 9 and 10, the pocket 32 is primarily for holding the material to be dispensed and pocket 34 is merely a result of providing the recessed neck for the convenient opening operation. Pocket 34 need not protrude as illustrated, but the packet may be arranged so that the periphery has a generally regular shape, for example a rectangle. The second pocket 34 may occupy a small portion thereof and the flange 38 may be slit so that the line 48 extends between edges of the flange without intersecting the pockets. A packet of this type may be utilized for dispensing various products, for example a large particulate material such as seeds.
The embodiment of FIGS. 11-17 is a modification of the embodiment of FIG. 1. Here the packet is separated into what is essentially two separate packets. Intermediate these twin packets, is a longitudinal slit 62 leading to the island 52. Perforations 64 represent a continuation of the slit 62 along which the packets may be divided for individual use, if desired. Even when joined these packets may be individually opened and utilized for dispensing, if desired. To rupture a single neck, a user can apply pressure at the swingline 48 as by spanning the neck with his thumb. As shown in FIGS. 14 and 15, one side can be easily broken open for dispensing of the contents. Alternately, the other side can be broken open for the same purpose. When both sides are ruptured, a user can hold one side in closed position while dispensing out of the other in a manner shown in FIG. 17. A typical utility of such twin packets is as a salt and pepper dispenser.
Various products may be dispensed from the dispensing packets of the present invention, for example particulate materials and liquids or semiliquids. The reduced neck portion limits the amount to be dispensed and the size thereof can be selected correlative to the material to be contained. When used for certain particulate materials, such as salt, pepper, or certain seasonings, the throat can be sized to provide a restriction so that shaking is neecessary to dispense the material. This gives the desirable result since the average individual is accustomed to dispensing seasonings of this nature by shaking action. Alternately, when a pouring action is desirable, as with sugar and liquids, the throat can be given a size for that result. The quantity of product placed in the packet can be measured when desirable, for example the packet can contain one teaspoon of sugar.
It can be seen that the present invention provides a dispensing packet in which a recessed pocket 32 is formed with an outwardly extending communicating neck 36 and a peripheral flange 38. A cover 31 is sealed to the flange 38 to retain the product in the pocket. The neck 36 has a reduced throat at a well-defined juncture 48 and the packet is swingable about a line 48 at the flange and extending crosswise of the neck to rupture the neck for dispensing. This provides an advantageous opening feature.
While it is contemplated that the present invention may be manufactured in various ways, it may be conveniently formed, filled, and sealed by the apparatus diagrammatically illustratd in FIG. 18. It is contemplated that thermoplastic materials may be utilized for the sheet 30, and cover member 31 may be of a flexible thermoplastic material of any type compatible with the container for sealing thereto. If desired, however, the cover member can be formed of sheets of material, such as paper or aluminum foil, coated with a material for sealing to the container. Preferably, the sheet 30 is of a material which is imperforate, yet will rupture under manual pressure as described above. In one embodiment, thin polystyrene is used for the sheet 30.
Referring now to FIG. 18, a roll 70 of thermoplastic material is supported adjacent one end of the machine. The sheet of material 30 is withdrawn from the roll and advanced longitudinally of the machine past successive stations. Heating heads 72 and 73 heat the sheet 30 so that it may be formed into the desired shape. At the next station the pockets and neck are pressure formed in the sheet 30 by a mandrel 74 adjacent one side of the sheet and pressure adjacent the other side. Sheet advancement is accomplished by a gripper 76 reciprocated by a piston 77 in the direction of arrows 78. After the sheet 30 is formed, it is advanced to a third station where the product to be dispensed is placed in the pockets. As illustrated, the container is of the embodiment of FIG. 11 and two products are simultaneously placed therein, for example salt S and pepper P. A second roll 80 of cover material is supported on the machine and the cover material 31 is withdrawn therefrom. Through proper selection of materials for cover material 31 and sheet 30, the two may be secured to each other by heat sealing. It should be understood, however, that other materials may be utilized and that other sealing methods may be used. As shown, cover member 31 is placed in juxtaposition to the flange 38 and the two are advanced to a sealing station 81 where the cover member 31 is sealed to the peripheral flange 38. At this point, a plurality of sealed dispensing packages are interconnected in a continuous web as illustrated in FIG. 18. The web is advanced to another station 84 where the dispensing packets are cut from the web by cutters 85 and 86. The completed packages are deposited on a conveyor 88 and the waste portion of the web is fed out of the machine.
