Description

  The present invention relates to a tablet cushioning material that is used by filling the upper surface of a tablet in order to guarantee the quality of the tablet stored in a packaging container such as pharmaceuticals and foodstuffs.

  In general, in a wide-mouth container containing a large number of tablets and capsules, to prevent breakage such as cracking or chipping of tablets due to the phenomenon of collision between tablets or the inner wall of the container due to vibration or impact action, Although cushioning materials such as maltoprene, polyethylene film, and cotton are housed in the upper part of the container, there is a problem in terms of hygiene because dust is likely to adhere during filling operations. At present, it is used with some problems in terms of user usability, operability at manufacturers, and economy. Especially for the polyethylene sheet cushioning material used in standard glass bottles, there is a specific problem with each pharmaceutical company regarding the defect that the tablet entangles the sheet when the end user removes the polyethylene sheet cushioning material. There is no solution and it is still a potential claim on the end user side. Some relatively large-capacity containers have been put into practical use with a shock-absorbing material integrally injection-molded with maltoprene or synthetic resin material, but are housed in recent standard glass bottles and the like. The tablets are relatively large in the amount of tablets stored, and the space in the upper part of the container is extremely small.

  In the cushioning material of molded products for large-capacity wide-mouth containers that are currently in practical use, there is a relatively large space between the stored tablet surface and the upper part of the container, and when inserting into the container, the external presser When the piece hits the mouth of the container and curves upward, it is reversed by elastic restoring force at the widened part of the body when inserted into the container, and the external presser piece is restored radially to the horizontal plane to hold the upper surface of the tablet. A cushioning material for tablets is commercially available.

Japanese Patent No. 3116274 Japanese Patent No. 3211082

  However, the three-dimensional tablet cushioning material described in Patent Document 1 and the planar tablet cushioning material described in Patent Document 2 are stored in the bottle upper surface and in the bottle as viewed from the standard glass bottle packaging. There is little space with the upper part, and in the form of cushioning material for molded products of current large containers, after inserting into the bottle, the external presser piece has no space to be reversed due to elastic restoring force, and the external presser piece is the mouth of the bottle There is a drawback that the neck portion of the mouth of the bottle is clogged in the upper direction when it hits the part and is clogged and the presser piece cannot press the upper surface of the tablet, and the function of the cushioning material for tablets is lost.

  Therefore, it is suitable as a buffer material for a conventional large-capacity wide-mouth container, regardless of the amount of tablets stored in the container, and can be easily inserted and removed, and can be formed simply. There is a need to develop a cushioning material that is hygienic, economical, and universally valid.

  The conventional three-dimensional cushioning material for tablets described in Patent Document 1 and the planar tablet cushion material described in Patent Document 2 described above have a tablet upper surface and a neck length portion of the inner diameter of the mouth depending on the filling amount of the tablet in the container. In the case of a wide space, the outer presser piece can hold the tablet in a substantially horizontal plane by elastic restoring action at the inner diameter of the container body, but in the case of a narrow space, the outer diameter presser piece is reversed in the container. When there is no space and hits the mouth part of the bottle and curls upward and becomes narrowed, it clogs the inner neck of the mouth of the bottle, making it impossible to press the tablet uniformly against the horizontal surface.

  Therefore, the cushioning material of the present invention can be easily inserted even in a packaging form in which the container is filled with a large amount of tablet and the space between the neck portion of the inner diameter of the mouth and the upper surface of the tablet is small, and a large-capacity tablet wide-mouth container The purpose of the present invention is to provide a tablet cushioning material having high versatility and epoch-making characteristics that can be flexibly adapted to standardized glass bottles and the like.

  In order to achieve the above object, the present invention takes the following technical means.

  In other words, the tablet cushioning material of the present invention is a molded product made of a synthetic resin material having appropriate elasticity in order to cope with the size of the space between the upper surface of the mouth and the upper surface of the tablet by changing the filling amount of the container. The conical ring-shaped rib and the handle part are formed obliquely from the inner wall surface slightly below the upper ring-shaped inner plug upper surface, and are formed at equal intervals with a slit from the lower part of the upper ring-shaped inner plug. The lower edge of the plurality of helical vertical ribs and the upper edge of the plurality of inclined ribs are connected by a hinge part, and the lower edge of the plurality of inclined ribs and the peripheral edge of the bottom disk are connected by a hinge part. Thus, a basket-type structure is formed integrally.

  In addition, the tablet cushioning material of the present invention is formed from an inner plug that is detachably fitted in the mouth portion of the tablet container and a lower part of the inner plug, and has a cylindrical shape with an interval in the circumferential direction. A plurality of spiral longitudinal ribs arranged, an inclined rib connected to the lower end of each longitudinal rib via a hinge portion, and a bottom disc, which are integrally formed of a synthetic resin material, The peripheral edge portion of each of the plurality of vertical ribs is connected to the lower end portions of the plurality of inclined ribs connected to the plurality of vertical ribs via hinges. In such a cushioning material for tablets, the inner stopper is formed in a ring shape, and the conical ring-shaped rib and the handle portion are integrally formed obliquely from the inner wall surface slightly below the upper surface of the inner stopper. Is preferred.

  In the above-described tablet cushioning material of the present invention, the vertical ribs and the inclined ribs can be formed in a band plate shape, and the circumferential width of the vertical ribs in a predetermined portion in the vertical direction can be made narrower than the width of the inclined ribs.

  Moreover, the straight part which does not exhibit a spiral form but extends straight with respect to the inclined rib can be provided at the lower end of the vertical rib.

  Furthermore, according to the cushioning material for tablets of the present invention, when the bottom disk is pushed up relatively with respect to the inner stopper by contacting the upper surface of the tablet in the container, the plurality of inclined ribs expand and the bottom disk and The upper surface of the tablet in the container is pressed and held by the bottom disk and the plurality of inclined ribs, and the plurality of helical vertical ribs are developed by the twisting action of the plurality of inclined ribs and inner plugs. The elastic vertical distance can be adjusted.

  Furthermore, the lower end portion of the longitudinal rib can be curved outward in the radial direction. According to this, the twisted twist deformation of the vertical rib when the cushioning material is pressed onto the upper surface of the tablet and the horizontal deformation of the vertical rib are more smoothly performed.

  As described above, the tablet cushioning material of the present invention can be easily inserted into the inner diameter of the mouth of the container in order to correspond to the size of the space between the upper surface of the mouth and the upper surface of the tablet by changing the filling amount of the container. The outer diameter of the plurality of vertical longitudinal ribs is smaller than the outer diameter of the upper ring-shaped inner plug that fits into the inner diameter of the container, and can be easily inserted without interfering with the inner diameter of the mouth of the container. .

  When the cushioning material of the present invention is inserted, when the bottom disk comes into contact with the upper surface of the tablet, a hinge part that connects the lower edge of the plurality of helical vertical ribs and the upper edge of the plurality of inclined ribs; In the configuration in which the lower edge of the inclined rib and the peripheral edge of the bottom disk are connected by a hinge portion, the plurality of inclined ribs are formed when a plurality of helical longitudinal ribs are pressed downward in the upper surface of the tablet. The inclined ribs of the bottom plate are hinge portions connected to the peripheral edge of the bottom disk, and the hinge portions connected to the lower edge of the plurality of helical vertical ribs and the upper edge of the plurality of inclined ribs are tablets. When pressed and moved in the direction of the inner diameter of the upper surface of the upper surface, the plurality of inclined ribs form a shape that changes into a presser piece that unfolds horizontally together with the bottom disk and presses the upper surface of the tablet.

  Furthermore, when the outer diameter portion of the upper ring-shaped inner stopper is fitted to the inner diameter of the container mouth, the plurality of spiral longitudinal ribs are inclined spiral ribs that are twisted clockwise with the hinge portion as a fulcrum. A plurality of spiral longitudinal ribs are transformed into twisted elastic ribs to form a cushioning material for tablets.

  The present invention provides a plurality of helical vertical ribs and a plurality of longitudinal ribs by the function of each of the hinge portions connecting the plurality of ribs and the bottom disk while being configured in such a three-dimensional and simple bucket shape. The inclined ribs and the cushioning material having an innovative feature have the function of changing the bottom disk into a pressing piece on the upper surface of the tablet by the pressing action after insertion into the container.

  For the removal of the bucket-type cushioning material, the handle is formed integrally with the conical ring-shaped rib obliquely from the inner wall surface slightly below the upper surface of the upper ring-shaped inner plug fitted to the inner diameter of the container. It can be easily taken out by hooking the back side of the circumferential part of the part from an arbitrary position with an index finger or the like.

  The form of the bucket-type cushioning material is a simple shape of a plurality of helical vertical ribs or a plurality of inclined ribs and a bottom disk, and is shaped like a bowl, so when inserted into a container, a tablet Inside the plurality of inclined ribs and the bottom disk connected to the spiral longitudinal ribs, the tablet does not enter.

  The conventional cushioning material with flat ribs and cylindrical ribs that press the tablet by bending the vertical ribs, the tablet enters the inside by the vibration action of the container from the gap between the vertical ribs and the vertical ribs due to vibration and impact of the container. Had a fatal flaw. However, the cushioning material of the present invention has a simple shape of a plurality of spiral longitudinal ribs and a plurality of inclined ribs and a bottom disk, and is shaped like a bowl, so when inserted into a container, A plurality of inclined ribs and bottom disc connected to the spiral longitudinal ribs form a tablet presser piece that is expanded horizontally to the body and inner diameter wall of the container by each hinge function to form a shape that presses the top surface of the tablet thoroughly. It has become. Therefore, it is a tablet cushioning material having a structure and a function that prevents tablets from leaking inward.

  Conventional three-dimensional or flat cushioning material is molded from low-density polyethylene, which is a synthetic resin material that has elasticity, so in complex shapes, there is a risk of deformation when transporting or moving. The bucket-type cushioning material according to the present invention is a tablet-shaped cushioning material having a feature that the quality of the appearance is stable because it has a ring-shaped shape with a ring-shaped inner plug and therefore has very few elements to be deformed.

  The cushioning material of the present invention has a simple shape such as a plurality of longitudinal longitudinal ribs, a plurality of inclined ribs, etc., but changes in the size and shape of the tablet, changes in the mouth inner diameter and body inner diameter of the container, tablet filling amount It is a tablet cushioning material that has the epoch-making feature that can effectively cope with the change in the amount of space in the upper space of the container due to the above, and has a versatile and economically significant effect.
