June 23, 1970 KlsABURo'lNo DISPENSER CLOSURE Filed sept. 5, 1968 ATTORNEY United States Patent O 3,516,536 DISPENSER CLOSURE Kisaburo Ino, Tokyo-to, `lapan, assignor to Hiroko Ino, Tokyo-to, Japan Filed Sept. 5, 1968, Ser. No. 757,694 Claims priority, application Japan, Nov. 7, 1967, 42/ 93,511 Int. Cl. B65d 83/ 04 U.S. Cl. 206-42 6 Claims ABSTRACT F THE DISCLOSURE This invention is related to a dispenser closure in the form of a bottle cap, through which tablets in the tipped bottle roll out one by one, so that the user can take just as many tablets as he needs. The outer surface of said cap has an outlet sized enough for one tablet to pass through. Across the inside of the cap is a channel wide enough for tablets to be aligned in it, and a part of said channel is connected to said outlet. When a bottle with said cap is tipped, tablets enter the channel to be aligned in it and then roll out from the outlet one after another in the order of alignment. When tablets in the tipped bottle rush to the inside of the cap, banks on both sides of the channel bear the weight of the tablets which have not entered the channel, so that the tablets aligned in the channel are not obstructed by the other tablet in rolling out from the outlet.
BACKGROUND OF THE INVENTION This invention relates to a dispenser closure or cap for closing a container such as a bottle, especially to a cap controlling the movement of tablets which are rolling out of a bottle.
Generally, in taking tablets out of a capped bottle, a person must first take off the cap and then tip the bottle so as to enable tablets to come out. In this way it is almost impossible to take just the necessary number of tablets out of the bottle, even if the bottle be tipped very carefully. When tablets are used for medicine or food, it is undesirable from a sanitary point of View to return extra tablets back into the bottle with the lingers. Actually, however, such an insanitary action is still repeated without any reilection. Moreover, the smaller the size of a tablet is, the more difficult it is to make no more tablets than desired roll out of a tipped bottle. When the tablets are so small as to be granule, it is impossible.
There is a known idea of a bottle cap with an outlet which is slightly larger than the size of one tablet, for the purpose of taking tablets out of a bottle one by one. Such a cap, however, has no means for aligning tablets toward the outlet or for preventing a number of tablets from rushing together to the outlet, from which no tablet can pass away.
Of course, it would be possible to provide a bottle cap with an elaborate system which will enable tablets to roll out from the outlet one after another. However, in view of the fact that bottles and caps generally are not expensive, the additional system should be simple enough to be made cheap. Otherwise, it would be of no utility value. Furthermore, a cap with an elaborate system is apt to bring about troubles and breakage, when it is used.
SUMMARY OF THE INVENTION It is a primary object of this invention to provide a dispenser closure which will avoid the above disadvantages of known caps.
Accordingly, it is an object of this invention to provide a bottle cap, by means of which tablets can roll out of a bottle exactly one at a time.
It is the second object of this invention to provide a bottle cap where tablets are aligned every time when the bottle is tipped, so that they can roll out of the bottle one after another.
It is the third object of this invention to provide a bottle cap enabling aligned tablets to go out from an outlet disposed in it one by one without being obstructed by the other tablets in a tipped bottle.
It is the fourth object of this invention to provide a bottle cap a construction of which not only meets all of the above objects but also is simple enough to make it possible to manufacture caps of this type at a low cost in large quantities, as manufacture of bottles.
Accordingly, the features of this invention are rather in a construction of the inside of a cap which is to be related to the interior of a bottle than in a construction of the outside of the cap. The cap of this invention has an outlet sized slightly larger than the size of one tablet. Said outlet forms an exit for tablets. The cap has proper thickness, across which a channel is cut, Said channel has a depth greater than the height of each tablet which rolls into it. In order to place tablets in alignment, the channel is wide enough to contain a single row of tablets but too narrow to admit two rows of them. This channel is connected to the outlet at one part of it and is open to the interior of the bottle at the other part of it.
When the above cap is iixed on a bottle and then the bottle is tipped, some of the tablets in the bottle are aligned in the channel and then roll out from the outlet one by one.
BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a plan view of an embodiment of a bottle cap according to this invention;
FIG. 2 is a bottom view of the bottle cap;
FIG. 3 is a sectional elevation along the line III-III of FIG. l and FIG. 2, showing a cover which is opened; and
FIG. 4 is a sectional elevation along the line IV-IV of FIG. 1 and FIG. 2.
DESCRIPTION OF A PREFERRED EMBODIMENT A cap 10 mainly consists of an outer wall 111, a sidewall 17 and a thick part 13 of the inside of the cap 10. If the outer wall 11 and the sidewall 17 are shaped by pressing a at metallic plate, the thick part 13 may be xed on the inside of the cap 10 with screw clamps or aggl'utinant. An outlet 12 bored in the outer wall 11 is preferably positioned on one side of the wall 11. In this embodiment a se'micircular cover 19 for closing said outlet 12 is provided so as to keep tablets from rolling out in case of a bottle rfalling down unexpectedly. Said cover 19 also serves to isolate tablets in the bottle from moisture of the air. However, if tablets are not badly influenced by the outer air the cover 19 is not always necessary. The part 13 of the inside of the cap 10 and the sidewall 17 are `formed with a space 18 between themselves. Said space 18 is provided for a bottle neck to enter. However, if the cap is inserted into a bottle neck, that is, a sidewall 17 of the cap fits an inside wall of a bottle neck, said sidewall and a part corresponding to the part 13 may be formed in one. A channel 14 is formed diametrically across the part 13 and has the outlet 12 on one side. Said channel 14 is slightly wider than a tablet T so that it can contain a row of tablets but cannot admit two rows. The depth of the channel 14 is a little greater than the diameter of the tablet T so that the tablet T may not project higher than banks `16 on both sides of the channel 14. In order to smooth the movement of tablets into the channel 14 and secure a certain number of tablets in the channel 14, it is preferable to pare off the sharp edges of the banks 16 to provide round edges 15. The round edges 15 are important to accomplish the objects of this invention without fail. The cover 19 is swingingly mounted on the outer surface 11 at a straight line 20 corresponding to its inner edge. The cover 19 has a tab 21 projecting toward the rim of the outer wall 11. As shown in FIG. 3, said tab 21 can be pushed up with the fingers so that the cover 19 may be raised up. On the back of the cover 19 is a projecting part 22 which is as large as the outlet 12. When the cover 19 is pushed down, said projecting part 22 ts into the outlet 12 to close it tight.
When the cap 10 having the screw threaded sidewall 17 is screwed on a bottle 24, tablets as many as needed are removed from the interior 23 of the bottle 24 in the following process. As soon as the bottle 24 is tipped, all the tablets in its interior 23 rush to the part 13 but only a certain number of them can enter the channel 14. As tablets roll into the channel 14, they are aligned too deep in the channel 14 to be obstructed by the load of the other tablets from going out through the outlet 12 one after another.
What is claimed is:
1. A dispenser closure to be connected to a container for dispensing therefrom tablets of a given size and configuration, said dispenser closure comprising an outer wall having opposed outer and inner surfaces and formed with a bore extending through said outer wall and having a size and configuration only large enough for one tablet to pass through said bore at one time, and a part fixed to said outer wall at said inner surface thereof and projecting inwardly from said inner surface through a depth greater than the largest transverse dimension of a tablet, said part being formed with a channel extending transversely across said part and completely through the latter up to said inner surface where said channel cornmunicates with said bore, said part being adapted to be received into the mouth of a container provided with the dispenser closure so that the channel will communicate with the interior of the container to receive tablets therefrom when the container is inverted, said channel having a width only slightly greater than the thickness of a tablet and a depth greater than the largest transverse dimension of a tablet so that only one row of tablets can become located in said channel at one time -for movement from said row one by one out through said bore.
2. The combination of claim 1 and wherein said bore is situated at the region of one end of said channel.
3. The combination of claim 2 and wherein said part has a pair of inner side surfaces directed toward each other to define said channel and said side surfaces being convexly curved at the region of said part distant from said outer wall and longitudinally of said channel to provide the latter with a cross section which flares at the end of the channel directed toward the interior of the container for facilitating movement of tablets into the channel.
4. The combination of claim 1 and wherein a cover is carried by said wall at the outer surface thereof for releasably covering said bore.
5. The combination of claim 1 and wherein said outer wall extends radially beyond said part, and a sidewall xed to and projecting from the outer periphery of said outer wall and defining with said part an annular space adapted to receive a container wall at the mouth thereof.
6. The combination of Claim 5 and wherein said sidewall is threaded to be threaded onto the exterior threaded surface of a container at the mouth thereof.
