Abstract

<P>PROBLEM TO BE SOLVED: To provide an inner plug which enables a desired number of tablets to be sufficiently taken out of a container easily with a simple structure and at a lower cost. <P>SOLUTION: The inner plug for tablet containers made of a resin is constituted of an outer cylinder assembled onto the internal surface of a mouth tube part, a working part provided in the outer cylinder and a support piece for movably supporting the working part. The working part normally keeps a clearance in between with the internal surface of the outer cylinder enough to block the passage of a tablet while being supported with the support piece so strongly as to discharge no tablet even under a dead load which may be applied by turning the container downward. When the clearance between the outer cylinder and the working part is expanded by pressing the working part with a finger or the like, the tablets are discharged outside the container through the clearance. As the pressing of the working part is released, the support piece works to return the working part to the original position, thereby stopping the discharge of the tablets. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to an inner stopper for a tablet container that allows a desired number of tablets to be easily taken out from the container without excess or deficiency.

  Conventionally, when taking out a tablet stored in a bottle or the like, the tablet is directly drained from the bottle onto the palm, a predetermined number of tablets are taken from the palm and put into the mouth, and the rest is returned to the bottle. .

  There is also known a tablet container that has a take-out mechanism and takes out a desired number of tablets from the container.

JP 2000-142841 A

  In the conventional bottle, the tablet touched by the hand is returned to the bottle again, and there is a possibility that the dirt on the hand adheres to the tablet. Moreover, even if it tried to make a tablet flow out from a container little by little, it was difficult to adjust operation, and it came out excessively and returned the tablet to the bottle in many cases. In addition, it is known that an inner stopper with a small opening is fitted into the mouth of a bottle and the small amount flows out from the opening. It was.

  Furthermore, in the container of the above invention, each time the button of the container is pressed, one or two predetermined number of tablets are taken out from the container, so the button must be operated many times until the required tablet comes out. There wasn't. Further, such a container take-out mechanism is composed of many parts, and much labor and cost are required for manufacturing parts, assembling and assembling them.

  An object of the present invention is to provide an internal stopper capable of easily taking out a desired number of tablets from a container without excess or deficiency, with a simple configuration and at low cost.

  The inner stopper for the tablet container was constructed as follows. The inner plug is made of resin and consists of an outer cylinder assembled to the inner surface of the mouth tube portion, an operating portion provided in the outer tube, and a support piece that movably supports the operating portion. The tablet is supported by the support piece with a strength that prevents the tablet from being discharged even if the tablet's own weight is applied with the container facing downward, and the operating part is pressed with a finger or the like. And when the clearance gap between an outer cylinder and an action | operation part was expanded, it comprised so that a tablet might be discharged | emitted out of a container through the clearance gap. Further, when the pressing of the operating part is released, the operating part is returned to the original position by the support piece, and the tablet discharge is stopped.

  Specifically, the inner plug was configured as follows.

  The outer cylinder is formed in a cylindrical shape that fits into the inner surface of the mouth of the container. It is formed so that it can be pressed, and a holding part is provided on the lower surface of the inner cylinder that extends toward the inner surface of the outer cylinder. The inner plug was connected to the inner cylinder.

  The inner plug may be formed from a plurality of parts, but it is desirable to integrally mold with a synthetic resin.

  The outer cylinder is closely fitted to the inner surface of the mouth tube portion of the container with an appropriate holding force. Further, the outer cylinder may be fitted to the mouth tube portion by undercut coupling or screw coupling.

  The actuating part is formed so that it can be actuated with fingers etc. with the container facing down, but it not only pushes and moves in the axial direction toward the inside of the container, but also the gap with the outer cylinder is enlarged If the tablet passes, the gap between the outer cylinder and the outer cylinder may be enlarged by tilting the inside of the outer cylinder or by pulling it out of the inner plug.

  Further, the operating portion may be provided not to be symmetric with respect to the central axis of the outer cylinder but to be offset from the center on one side of the inner surface of the outer cylinder. Further, the operating portion may be formed of a disc and a projecting piece attached to the disc, and the projecting piece may be pressed to discharge the tablet.

  The support piece is formed to have such a strength that the tablet does not fall from the inside with the container facing downward, and the operating part is easily operated and the tablet is discharged when the operating part is operated. In addition, when the operation of the operating portion is released, it is formed with a restoring force that reliably stops the discharge of the tablet. The support piece may connect the outer cylinder and the inner cylinder through the upper portion of the inner plug without passing through the lower portion of the inner plug. In short, it is only necessary to form a gap through which the tablet passes between the outer cylinder and the working piece.

  The support piece is preferably formed evenly with respect to the central axis of the outer cylinder, but may have other configurations and arrangements. Further, the operating part may be hinge-coupled to the inner surface of the outer cylinder, and the hinge-coupled operating part may be held by a support piece with an appropriate holding force.

  In a container equipped with an internal stopper, even if the tablet is accommodated and the container is turned downward, the tablet is not discharged from the container. Then, when the operating part is operated and operated with the belly of the finger or the like in the state of being directed downward, the tablet is discharged. The operating portion gradually moves according to the operation and widens the gap between the outer cylinder and the tablet can be discharged while checking. Therefore, it is possible to take out only one tablet and stop it. Alternatively, the tablet can be discharged continuously, and when the desired number of tablets has been discharged, the operation of the operating unit is released to stop the discharge of the tablet. Any number of tablets can be removed.

  Since the tablet is not returned from the hand to the container, the tablet can be stored hygienically. Anyone can easily operate the inner plug and take out the required number of tablets from the container.

  The inner plug can be integrally molded with resin, so no assembly process is required and it can be provided at low cost.

  8 and 9 show a tablet container 30 to which the inner stopper 2 is attached. The tablet container 30 has a mouth tube part 32 at the upper part, and the inner plug 2 is fitted to the inner surface of the mouth tube part 32. A male screw 34 is formed on the outer peripheral surface of the mouth tube portion 32, and a cap 36 is screwed into the male screw 34. The tablet container 30 stores the tablet A therein.

  The inner plug 2 has a cylindrical shape as shown in FIG. 3, and includes an outer cylinder 4, an inner cylinder 6 as an operating part, and a support piece 8 as shown in FIG. 1. The inner plug 2 is formed by integral molding with resin.

  The outer cylinder 4 has a substantially uniform outer diameter in which the upper half is fitted to the inner surface of the mouth cylinder 32, and the lower half is tapered so that the diameter gradually decreases. On the upper part of the outer cylinder 4, a collar 10 is formed which protrudes outward from the outer cylinder 4 and is applied to the upper end of the mouth tube part 32.

  As shown in FIG. 2, the inner cylinder 6 is provided coaxially with the outer cylinder 4 on the inner side of the outer cylinder 4, and has almost the same height as the collar 10 (does not come out above the collar 10). It is formed as follows. A holding piece 12 as a holding portion is provided at the lower end of the inner cylinder 6. The holding piece 12 extends to the outside of the inner cylinder 6 and faces the same position as the lower end of the outer cylinder 4, and a gap d is formed between the inner surface of the outer cylinder 4. The gap d in this state is a distance through which the tablet A does not pass. The inner cylinder 6 has a slight gradient in the vertical direction so that the mold can be easily removed.

  As shown in FIG. 4, the support piece 8 is bent under the inner plug 2 and is connected to the lower ends of the outer cylinder 4 and the inner cylinder 6. The support pieces 8 are evenly arranged at three locations, have a predetermined thickness and width so as to support the inner cylinder 6 with a predetermined holding force, and are shown in FIG. 5 when the inner cylinder 6 is pressed. Thus, the gap d is long enough to expand until the tablet A passes therethrough.

  Specifically, the support piece 8 has a holding force that prevents the tablet A from flowing out even when the tablet container 30 to which the inner plug 2 is attached is filled with a prescribed amount of tablet A, the cap 36 is opened, and the mouth tube part 32 is directed downward. And the flexibility which can be moved until it presses the inner cylinder 6 and flows out the tablet A, and if it cancels | releases, it has the restoring property which returns to the present condition. Furthermore, the support piece 8 is integrally molded with the outer cylinder 4 and the inner cylinder 6.

  Next, the operation of the tablet container 30 to which the inner plug 2 is attached will be described.

  FIG. 8 shows a tablet container 30 in which tablets A are stored. The tablet A has a size and shape that does not flow out of the gap d between the outer cylinder 4 and the inner cylinder 6 in a normal state. The tablet container 30 is sealed with a cap 36.

  When taking out the tablet A, the cap 36 is opened, and the tablet container 30 is tilted so that the mouth tube portion 32 faces downward as shown in FIG. In this state, the tablet A does not flow out of the tablet container 30. Then, the inner cylinder 6 is pressed with the belly of the finger or the like and pressed into the tablet container 30. Then, as shown in FIG. 7, the gap d between the outer cylinder 4 and the inner cylinder 6 increases, and the tablet A begins to flow out from the gap d. When a predetermined number of tablets A flow out, the pressing of the inner cylinder 6 is stopped, the gap d is narrowed, and the tablet A outflow is stopped.

  Therefore, a desired number of tablets A can be taken out arbitrarily and easily by pressing the inner cylinder 6 as appropriate. Since a desired number of tablets A can be taken out, the taken out tablets A are not returned to the container.

  Since the inner plug 2 can be integrally formed of resin, the manufacturing cost is low, the assembly is unnecessary, the assembly into the container is facilitated, and the cost can be greatly reduced.
