Description:
BACKGROUND OF THE INVENTION
Multicompartment dispensing containers may be conveniently used for storing, merchandising, and dispensing various commodities such as pills or other medicaments, spices, condiments, or other suitable commodities.
Prior art multicompartment containers include those disclosed in U.S. Letters Patent Nos. 3,382,969 and 3,552,595. Many of the prior art devices are molded from a plurality of pieces or, if molded from a single piece, involve extensive molding or casting in order to achieve the desired result. Furthermore, such prior art devices may not permit simultaneous charging of all compartments and individual discharging from selected compartments.
The present invention is characterized by a simple more economical structure moldable as a one-piece item and adaptable as molded for simultaneously charging a plurality of compartments and selectively dispensing from each individual compartment. The invention accomplishes this by providing a device which is characterized by a peripheral or marginal wall of rectangular configuration having four front facing marginal edges and four rear facing marginal edges. A front panel covers the front of the opening defined by the marginal wall and is integral with the marginal wall along the four front facing marginal edges. The front panel is provided with a plurality of dispensing flaps defined by portions of reduced thickness adjacent one of the front marginal edges. A rear charging panel covers the rear of the opening defined by the marginal wall. The rear charging panel is continuously integral with one of the rear facing marginal edges and is molded in the opened position to permit charging. The juncture of the rear charging panel with the marginal wall is of thinner cross section whereby the rear panel is hingedly secured to the marginal wall to permit closing thereof.
There is also provided a plurality of parallel partition members extending between and integral with the marginal wall at opposite sides thereof and integral with the front panel along the edges of the partition members which are in confronting relation with the front panel, thereby defining a plurality of compartments with the front and rear panels and with the marginal walls. The dispensing flaps in the front panel provide individual selective access to each of the compartments.

DETAILED DESCRIPTION OF THE DRAWINGS
Referring now more particularly to the drawings, there is shown a one-piece molded container in accordance with the present invention. The materials from which this device is most conveniently formed are polyethylene or polypropylene. The device is characterized by a peripheral or marginal wall 10 defining a rectangular opening. The marginal wall 10 has four front facing edges 11, 12, 13, and 14 (FIG. 1) and four rear facing edges 15, 16, 17, and 18 (FIG. 4).
A front panel 22 covers the front of the opening defined by the marginal wall 10 and is integral therewith along the front facing edges 11, 12, 13, and 14.
There is also provided a charging flap or rear panel 28 which is dimensioned to cover the rear of the opening defined by the marginal wall 10 and which is continuously integral with the marginal wall 10 along the rear facing marginal edge 16. The juncture 30 of the rear panel 28 with the marginal wall 10 is of thinner cross-section than the rear panel 28, as best shown in FIGS. 3 and 5, whereby the rear panel 28 is hingedly secured to the marginal wall 10.
The container as shown in the annexed drawings also includes a plurality of parallel partitions 32 extending between and integral with the marginal wall 10 at opposite sides thereof, and integral with the front panel 22 along the edge of each partition 32 which confronts the front panel 22. When the rear panel 28 is closed, the rear panel 28 fits inside the rear facing marginal edges 15, 17 and 18. The partition members 32 then define with the front and rear panels 22 and 28 and with the marginal wall 10 a plurality of individual isolated compartments, and the closed rear panel 28 provides a common wall for all of the individual compartments.
As best shown in FIG. 5, the front panel 22 is also provided with a plurality of rectangular dispensing flaps 42 disposed along the edge of the front panel 22 which is adjacent the front facing marginal edge 14. The dispensing flaps 42 are molded integrally with the front panel 22 and are defined by reduced thickness side portions 43 (FIG. 6), top portions 44 (FIG. 5), and rearward portions 45 (FIG. 5). In this manner, the flaps 42 as molded provide leak-proof closures for the individual compartments prior to dispensing. When the contents of any one compartment are to be dispensed, the flaps 42 associated with such compartment is opened as shown in FIG. 5 by lifting the flap 42 and rotating it about the reduced thickness top portion 44 toward the front facing marginal edge 12 to break the reduced thickness side portions 43 and rear portion 45.
After each dispensing flap 42 has once been opened, the elastic memory of its reduced thickness connection 44 to the front panel 22 is sufficient to retain the flap 42 closed when relatively large items, such as pills, are carried by the compartments. However, when other materials, such as spices, condiments or the like are carried by the compartments, it may be desirable to provide a positive snap locking means, such as a suitable beveled lip on the front facing marginal edge 14, to retain each dispensing flap 42 in its closed position.
As best seen in FIG. 5, the rear panel 28 is also provided with a beveled edge 50 which, with a force sufficient to overcome the elasticity of the plastic from which the device is made, may be snapped into position behind a suitable beveled lip 52. In this manner, the rear panel 28, which is biased to the opened position by the elastic memory of the hinged connection 30 due to being molded in the opened position for charging purposes, is positively mechanically locked in its closed position after the container has been filled.
The device is molded as a single piece with the charging flap or rear panel 28 in the opened position as shown in FIG. 3 and with the dispensing flaps 42 in the closed position, as described above. The molded open individual compartments, which are defined by the marginal wall 10 and the partitions 32 and the front wall 22, are manually or automatically filled with the desired material, which may be pills or other medicaments, spices, condiments, or other suitable material. The rear panel 28 is then closed and frictionally retained in position by the lip 52. Thereafter, the individual dispensing flaps 42 may be selectively individually opened whereby the material contained in each associated compartment may be selectively removed.
Multicompartment dispensing containers may be conveniently used for storing, merchandising, and dispensing various commodities such as pills or other medicaments, spices, condiments, or other suitable commodities.
Prior art multicompartment containers include those disclosed in U.S. Letters Patent Nos. 3,382,969 and 3,552,595. Many of the prior art devices are molded from a plurality of pieces or, if molded from a single piece, involve extensive molding or casting in order to achieve the desired result. Furthermore, such prior art devices may not permit simultaneous charging of all compartments and individual discharging from selected compartments.
The present invention is characterized by a simple more economical structure moldable as a one-piece item and adaptable as molded for simultaneously charging a plurality of compartments and selectively dispensing from each individual compartment. The invention accomplishes this by providing a device which is characterized by a peripheral or marginal wall of rectangular configuration having four front facing marginal edges and four rear facing marginal edges. A front panel covers the front of the opening defined by the marginal wall and is integral with the marginal wall along the four front facing marginal edges. The front panel is provided with a plurality of dispensing flaps defined by portions of reduced thickness adjacent one of the front marginal edges. A rear charging panel covers the rear of the opening defined by the marginal wall. The rear charging panel is continuously integral with one of the rear facing marginal edges and is molded in the opened position to permit charging. The juncture of the rear charging panel with the marginal wall is of thinner cross section whereby the rear panel is hingedly secured to the marginal wall to permit closing thereof.
There is also provided a plurality of parallel partition members extending between and integral with the marginal wall at opposite sides thereof and integral with the front panel along the edges of the partition members which are in confronting relation with the front panel, thereby defining a plurality of compartments with the front and rear panels and with the marginal walls. The dispensing flaps in the front panel provide individual selective access to each of the compartments.

DETAILED DESCRIPTION OF THE DRAWINGS
Referring now more particularly to the drawings, there is shown a one-piece molded container in accordance with the present invention. The materials from which this device is most conveniently formed are polyethylene or polypropylene. The device is characterized by a peripheral or marginal wall 10 defining a rectangular opening. The marginal wall 10 has four front facing edges 11, 12, 13, and 14 (FIG. 1) and four rear facing edges 15, 16, 17, and 18 (FIG. 4).
A front panel 22 covers the front of the opening defined by the marginal wall 10 and is integral therewith along the front facing edges 11, 12, 13, and 14.
There is also provided a charging flap or rear panel 28 which is dimensioned to cover the rear of the opening defined by the marginal wall 10 and which is continuously integral with the marginal wall 10 along the rear facing marginal edge 16. The juncture 30 of the rear panel 28 with the marginal wall 10 is of thinner cross-section than the rear panel 28, as best shown in FIGS. 3 and 5, whereby the rear panel 28 is hingedly secured to the marginal wall 10.
The container as shown in the annexed drawings also includes a plurality of parallel partitions 32 extending between and integral with the marginal wall 10 at opposite sides thereof, and integral with the front panel 22 along the edge of each partition 32 which confronts the front panel 22. When the rear panel 28 is closed, the rear panel 28 fits inside the rear facing marginal edges 15, 17 and 18. The partition members 32 then define with the front and rear panels 22 and 28 and with the marginal wall 10 a plurality of individual isolated compartments, and the closed rear panel 28 provides a common wall for all of the individual compartments.
As best shown in FIG. 5, the front panel 22 is also provided with a plurality of rectangular dispensing flaps 42 disposed along the edge of the front panel 22 which is adjacent the front facing marginal edge 14. The dispensing flaps 42 are molded integrally with the front panel 22 and are defined by reduced thickness side portions 43 (FIG. 6), top portions 44 (FIG. 5), and rearward portions 45 (FIG. 5). In this manner, the flaps 42 as molded provide leak-proof closures for the individual compartments prior to dispensing. When the contents of any one compartment are to be dispensed, the flaps 42 associated with such compartment is opened as shown in FIG. 5 by lifting the flap 42 and rotating it about the reduced thickness top portion 44 toward the front facing marginal edge 12 to break the reduced thickness side portions 43 and rear portion 45.
After each dispensing flap 42 has once been opened, the elastic memory of its reduced thickness connection 44 to the front panel 22 is sufficient to retain the flap 42 closed when relatively large items, such as pills, are carried by the compartments. However, when other materials, such as spices, condiments or the like are carried by the compartments, it may be desirable to provide a positive snap locking means, such as a suitable beveled lip on the front facing marginal edge 14, to retain each dispensing flap 42 in its closed position.
As best seen in FIG. 5, the rear panel 28 is also provided with a beveled edge 50 which, with a force sufficient to overcome the elasticity of the plastic from which the device is made, may be snapped into position behind a suitable beveled lip 52. In this manner, the rear panel 28, which is biased to the opened position by the elastic memory of the hinged connection 30 due to being molded in the opened position for charging purposes, is positively mechanically locked in its closed position after the container has been filled.
The device is molded as a single piece with the charging flap or rear panel 28 in the opened position as shown in FIG. 3 and with the dispensing flaps 42 in the closed position, as described above. The molded open individual compartments, which are defined by the marginal wall 10 and the partitions 32 and the front wall 22, are manually or automatically filled with the desired material, which may be pills or other medicaments, spices, condiments, or other suitable material. The rear panel 28 is then closed and frictionally retained in position by the lip 52. Thereafter, the individual dispensing flaps 42 may be selectively individually opened whereby the material contained in each associated compartment may be selectively removed.
