Description

Tablet dispenser

The present invention relates to be used for providing continuously the tablet dispenser of tablet, especially relate to such distributing box, be that it comprises bulge and circular lid, in this bulge, tablet is stored in along in the separate space of the circumferential distribution of this container, and this circle lid is concentric with this container, and this lid covers this separate space, and dispense aperture is arranged, when this lid rotated with respect to container, this dispense aperture allowed to enter a separate space.

In known distributing box, lid can wind by with the concentric container of described container in the supporting member that forms of cylindrical wall and with respect to the container rotation, this wall forms the axle journal of lid, this lid has the central opening around described cylindrical wall.This opening has sawtooth along its periphery, and this sawtooth includes the tooth of sloping edge and brink.Projection in this sawtooth and the described supporting member cooperates, and this convexes to form similar tooth, and the sloping edge of this tooth is facing to the sloping edge of the interior tooth of lid opening.Like this, when lid during with the rotation of direction, the sloping edge of the tooth of the sloping edge of the tooth of lid and projection will slip over mutually, and when lid during with opposite spin, two brinks that overlap teeth will be meshing with each other and stop this rotation.

When the sloping edge of the tooth of lid slips over the sloping edge of tooth of the projection on the cylindrical wall, this wall will be out of shape and press to its center.It is very big to produce the required power of described distortion, thereby even also be difficult to make the lid rotation when all providing axial groove on each side of projection, therefore, this cylindrical wall is divided into the littler part of hardness.Make more weakly and more pliable and tougher if will have the cylindrical wall portion of projection, then when attempting with the rotation of unallowed direction, these cylindrical wall portion also will be easier to bend and open.If this tooth is lower, so that make the easier rotation of lid, so, the difference that rolls across between (cam over) required power of cam is also less each other to make lid slip over the required power of such permission direction rotation and the brink that makes tooth each other with the sloping edge of tooth, and the escapement function is possible destroyed.

The tablet dispenser that the purpose of this invention is to provide a kind of described circle, wherein, the lid assign direction rotation to allow at an easy rate, and destroy this escapement function and make this lid obviously bigger with the required power of opposite spin.

This purpose is to realize by a kind of tablet dispenser that is used for providing continuously tablet, especially such distributing box, be that it comprises bulge and circular lid, in this bulge, tablet is stored in along in a plurality of separate spaces of the circumferential distribution of this container, this circle lid is concentric with this container, and this lid covers this separate space, and dispense aperture arranged, when this lid rotates with respect to container, this dispense aperture allows to enter a separate space, and wherein, the cylindrical surface on the parts in these parts of container piece or lid forms pawl wheel, this pawl wheel has tooth, each tooth all has sloping edge and brink, and another parts have the escapement that matches with described tooth, so that only allow the mutual unidirectional rotation of these parts, distributing box of the present invention is characterised in that: this escapement comprises the flexible ratchet that at least one is elongated, this ratchet is fixed on described another parts at the one end, and substantially along the string of circular device, cooperates with the tooth of pawl wheel so that pass through another free end of this ratchet.

When be subjected to perpendicular to its longitudinally bending force do the time spent, described ratchet is flexible, in fact this situation that is ratchet when the sloping edge of tooth slides, but, when the power that is subjected to along its longitudinal direction, described ratchet is actually rigidity, and in fact this is the brink of the tooth situation when pressing the free end of ratchet.

Can make it have enough elastomeric length in order to guarantee that ratchet has, the arc of ratchet leap is suitably at least 30 °, preferably about 60 °.

In distributing box preferred embodiment of the present invention, three ratchets each other in about 120 ° spaced apart.

In the preferred embodiment of distributing box of the present invention, tooth is on the inside face of the ring that is formed by separate space, and ratchet is contained on the lid.Described inside face makes this cylindrical surface can obtain maximum diameter, therefore allows the tooth of sloping edge high as far as possible, that have given gradient.The number that shall also be noted that tooth is corresponding with the number of the separate space of container, and like this, ratchet is once through a tooth, and dispensing a slice tablet.

The container piece of tooth being arranged and the lid spare of ratchet is arranged can be Unitarily molded parts.

Present invention is described in more detail below with reference to the accompanying drawings, in the accompanying drawing:

Figure 1 shows that the exploded drawings of the distributing box of prior art;

Figure 2 shows that the exploded drawings of distributing box of the present invention;

Figure 3 shows that the partial view of distributing box, wherein, lid is installed on the container part, and the part lid is cut open to disclose the cooperation between ratchet and the pawl wheel.

The distributing box of prior art shown in Figure 1 comprises the conglobate bottom parts of cardinal principle 1, conglobate lid spare 2 of cardinal principle and conglobate date indicator 3 substantially.

Bottom parts 1 is provided with a plurality of separate spaces 4 in the chunk ring 5 of a part that constitutes described bottom parts 1.This lid spare 2 has central opening, and lid spare can be by this central opening on the area supported 9 of journal rest in the cylindrical wall that is made of a plurality of parts 6 and 7 that stand vertically from the bottom 8 of bottom parts 1.The part that forms cylindrical wall has two kinds.Long part has projection 10 on its area supported 9, and short part also has hook-type upper limb 11 except the projection on its area supported 10, when this opening was engaged on the described hook-type edge 11, this hook-type upper limb 11 made lid spare 2 journal rests on the area supported 9 of cylindrical wall.

Lid spare 2 has a plurality of teeth 12 that cooperate with the projection 10 of area supported 9 on the heart opening therein, and this central opening journal rest is on the area supported 9 of the cylindrical wall of bottom parts 1.This tooth 12 is the same with projection, an one precipitous edge and a bevelled edge all arranged, and be oriented like this, promptly when lid spare 2 rotates with respect to bottom parts 1 with a direction, the sloping edge of tooth and projection slips over mutually, and when lid spare was attempted to rotate in the opposite direction, the brink of projection withstood the brink of tooth 12, thereby prevented to rotate.Because when the sloping edge of tooth 12 and projection 10 slips over each other, part 6 and 7 pressurizeds and to the center curvature of distributing box, so allow to be rotated, arrive up to brink, clatter is sent in the part rebound simultaneously, and the rotation that expression has been carried out enough distributes a tablet.But, the length of part is very short, and because their cambers, part is quite hard, and therefore, tooth and projection must be very low.This cause when crooked part rebounds fast clatter quite a little less than, and interlock is less by required power each other to make brink.

When lid spare 2 was installed on the bottom parts 1, it can rotate, so that carry out the distribution of a tablet during by dispense aperture continuously, this dispense aperture is opened after destroying sealing 13.This seals and guarantee that this product is new and not used when buying.

At last, date indicator 3 can also be housed.With the (not shown) the days of the week, like this, the user that should eat a tablet in a day can know that she had eaten tablet today to this indicating device along its periphery order.By the free-running fit between a pair of in the projection 14 on the cylindrical wall 15 that makes date indicator and a plurality of rib 16, date indicator is locked on one group of position of rotation with respect to bottom parts 1, and this rib 16 is on the part 6 and 7 inboards of the cylindrical wall that forms bottom parts 1.Locking between date indicator 3 and the bottom parts 1 is very firm, to such an extent as to when only useful tool makes this date indicator 3 with respect to bottom parts 1 rotation, just can overcome this locking.This instrument can be a coin, this coin is inserted in the fringing groove (kerb) 17 of date indicator 3, so that make this date indicator 3 rotate to such position, promptly write on the position and the aligned in position of sealing 13 on date on the date indicator, that conform to date that this device is brought into use, then, tear this and seal 13 so that take out first tablet of tablet.On the date subsequently, make the lid rotation with a slice tablet under the dispensing, this tablet forms block, prevents that this lid rotation from surpassing a pitch.After, this opening will be all align every day on date on the date indicator, that conform to actual date.

Figure 2 shows that the exploded drawings of distributing box of the present invention.This distributing box also comprises bottom parts 21, lid spare 22 and date indicator 23.

Bottom parts 21 has a plurality of separate spaces 24 in the chunk ring 25 of a part that constitutes described bottom parts 21.This lid spare 22 has central opening, lid spare can be by this central opening journal rest on the formed area supported of cylindrical wall that constitutes by a plurality of parts 26 and 27 that alternately stand vertically from the bottom 28 of bottom parts 21.Part 26 edge thereon has hook 31, and when the opening of described lid spare and 31 engagements of described hook, this hook 31 makes lid spare 22 journal rests on the area supported of cylindrical wall.Part 27 has the flexible latch arm 36 of band projection 38 in its side towards the cylindrical wall center, this projection 38 can cooperate with the recess 39 on the sagging cylindrical wall 40 of date indicator 23.

The inside circumference of chunk ring 25 has the ratchet gear teeth 32, and these ratchet gear teeth 32 have brink and sloping edge, and these ratchet gear teeth 32 cooperate with ratchet 30 on the lid spare 22, as shown in Figure 3.

In the illustrated embodiment, three ratchets 30 are arranged on lid spare 22.These ratchets 30 are elongated plastic item, one end of this elongated plastic item is by integrally molded with described lid spare and link to each other with this lid spare 21, and it is spaced apart that these plastic item are in hexagonal angle, and locate like this, be their strings, and when this lid is installed on the bottom parts 21, form by the ratchet gear teeth 32 formed internal pawl of described bottom parts 21 and take turns string on the determined circle along circular lid spare.This ratchet is located like this, promptly when lid rotates on the supporting member that is formed by part 26,27, ratchet, be installed in fixed end on the lid can be just through the top of the ratchet gear teeth of bottom parts, and the free end of this ratchet 30 cooperates with the ratchet gear teeth, and only allow with such direction rotation, promptly, on this direction, when the free end of ratchet slips over the sloping edge of this tooth, the free end of ratchet can be bent and open, by the terminal of inclined-plane and rebound and clash into the sloping edge of next tooth, produce sharp-pointed clatter up to them simultaneously.When with opposite spin, the free end of ratchet props up the brink of tooth, and this contrarotation is blocked, because ratchet is subjected to along its power longitudinally, therefore will be difficult to curved opening.

In the illustrated embodiment, lid has the groove 34 on ratchet 31.This groove is for the ease of molded.And, lid have with Fig. 1 in seal and 13 correspondingly seal 33.
