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 or capsules, to prevent breakage such as cracking or chipping of tablets due to the phenomenon of collision between tablet tablets or the inner wall of the container due to vibration or shock. 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 the filling operation. At present, it is used with some problems in terms of user usability, operability at manufacturers, and economy. In particular, the polyethylene sheet cushioning material used in standard glass bottles is also specific to each pharmaceutical company, etc., regarding the defect that the tablet entangles and pops out when the end user takes out 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 amount of tablets stored is relatively large, and the upper space of the container has become extremely small.

In the cushioning material for 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, an external presser piece Will hit the container mouth and bend upward, and when inserted into the container, it will be reversed by the elastic restoring force at the widened part of the body, and the external presser will be restored radially to the horizontal surface to hold the tablet upper surface. It has a structure and function that can be done.

However, the three-dimensional tablet cushioning material of JP-A-10-7205), and the JP-A-9-290863 planar type, tablet cushioning material, etc. are the upper surface of the tablet and the upper part of the bottle stored as viewed from the standard glass bottle packaging. In the form of the cushioning material of the current molded product of a large container with little space, after inserting into the bottle, the external presser piece has no space to reverse due to elastic restoring force and the external presser piece hits the mouth of the bottle There is a drawback in that the function of the cushioning material for tablets is lost because the inner neck of the mouth of the bottle is clogged in the upward direction and is clogged, and the presser piece cannot press the upper surface of the tablet.
In addition, utility model registration No. 2074596 (Japanese Utility Model Publication No. 6-44848) The cushioning material for tablets spread radially like a tilted umbrella through a minimal slit when inserted into a bottle. The presser piece and the presser piece come into contact with each other and can be narrowed to pass through the inner diameter of the mouth and the neck long part, and can be inserted into the inner diameter part of the trunk, and the center pole extending in the center of the center desk is pushed downward. However, the external presser has a structure and function that spreads and presses the upper surface of the tablet, but has the following drawbacks.

The above-mentioned umbrella-shaped presser piece is basically always limited in the minimum slit width based on the inner diameter of the bottle mouth, and when the presser piece is deployed on a substantially horizontal surface, the slit width is the inner diameter of the bottle body. The larger the size, the wider the slit width and the easier the tablet pops out. In addition, the outer diameter of the presser piece, which is narrowed like an umbrella, has a small gap between the bottle inner diameter and, for example, numerically, the gap between the mouth inner diameter and the presser piece diameter is about 1 mm and the gap on one side is 0.5. Since it is about a ridge, it is likely to interfere with the inner diameter of the container in the actual insertion operation, and the insertion is difficult. In addition, when the center pole extended in the center of the center desk is pushed downward, the external presser piece spreads and presses the top surface of the tablet, but the presser piece that is narrowed from the mouth neck to the top of the tablet It is necessary to operate the space distance of approximately horizontal plane, but the timing of the center pole does not match the timing, and after the squeezed umbrella-shaped external presser piece contacts the top surface of the tablet, the center pole is moved downward. When pressed down, there is a defect of scooping up the tablet, and it is difficult to satisfactorily press the tablet upper surface, and it has not been put into practical use. Accordingly, it is necessary to develop a cushioning material having a universally reasonable form that is hygienic and economical, instead of the cushioning material, regardless of the amount of tablets stored in the container. .
Japanese Patent No. 3116274 (Japanese Patent Laid-Open No. 10-72055) Japanese Patent No. 3211082 (Japanese Patent Laid-Open No. 9-290863) Utility Model Registration No. 2074596 (Japanese Utility Model Publication No. 6-44848)

The conventional three-dimensional cushioning material for tablets and the cushioning material for flat tablet tablets disclosed in Japanese Patent Laid-Open No. 10-72055 described above are the upper surface of the tablet and the neck length 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 the elastic restoring action at the inner diameter of the container, but in the case of a narrow space, the outer diameter presser piece is reversed in the container. It is impossible to press the tablet uniformly on the horizontal surface because there is no space for the clogging and the upper neck portion of the bottle is clogged and depressed in the upper direction when it hits the mouth of the bottle.

In addition, the umbrella-type tablet cushioning material has a shape in which the presser piece is formed radially like an umbrella from the beginning, and has a function of pushing the center pole downward, but the presser piece has a radial shape. In this state, the center pole is pushed downward after coming into contact with the upper surface of the tablet, and there is a drawback that the upper surface of the tablet is scooped up when deployed on a horizontal surface.

Therefore, the present invention is a disadvantage of the above-described cushioning material, and can be easily inserted even in a packaging form in which the container has a large tablet filling amount and a small space between the neck portion of the inner diameter of the mouth and the upper surface of the tablet. This is a shape that can also be applied to tablet containers using flat type cushioning materials, and the width of the presser piece is not restricted by the mouth inner diameter of the container. Is a tablet cushioning material of the present invention having an epoch-making feature that can be arbitrarily formed with a small slit width. The tablet wide mouth container is a large-capacity container, or a standard small-sized container. An object of the present invention is to provide an economical tablet cushioning material that is compatible with glass bottles and the like and has high versatility.

In order to achieve the above-mentioned object, the following solution is taken in the cushioning material according to the present invention. That is, in the present invention, a molded product made of a synthetic resin material having an appropriate elasticity and corresponding 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. 1) A plurality of upper vertical ribs (2) are connected at equal intervals from the inner diameter lower part of the intermediate ring (3) to the upper edge surface of the intermediate ring (3), and are radially spaced from the outer edge of the bottom disk (5) through the slit (10). The edges (6a) (7a) of the plurality of bottom pressing pieces (6) (7), the base parts (8a) (9a) of the outer pressing pieces (8) (9), and the lower edges of the lower rib (4) are connected. The upper edge of the lower rib (4) is connected to the lower edge surface of the intermediate ring (3), and the bottom presser piece (7) has a bottom disk (5). A hinge-shaped groove (7b) is provided at a position close to the outer edge of the bottom edge of the bottom pressing piece (6). The hinge-shaped groove (6b) is provided at a position close to the edge (6a), and the bottom disk (5) is formed on the upper surface of the bottom pressing piece (6) from the center position of the hinge-shaped groove (6b). A triangular reinforcing rib (14) is provided on the outer peripheral surface of the cylindrical pole (11) formed on the upper surface of the cylindrical pole (11), and a plurality of rectangular shapes are formed from the upper edge surface of the cylindrical pole (11). The rib (12) is connected, and a rod-shaped pole (13) is formed at the center of the bottom disk (5).

As described above, the tablet cushioning material of the present invention can be applied from the lower part of the inner diameter of the upper ring-shaped inner plug (1) in order to accommodate 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 intermediate ring (3) and a plurality of vertical ribs (2) are connected at equal intervals. The diameter of the intermediate ring (3) is smaller than that of the conventional bottom disk and the slit (10) is separated from the outer edge of the bottom disk (5) in the radial direction. A plurality of bottom pressing pieces (6) (7) are provided, and the edge portions (6a) (7a), the base portions (8a) (9a) of the plurality of external pressing pieces (8) (9), and a plurality of lower portions The lower edge of the rib (4) is formed to be connected, and the lower rib (4) is the same number of elastic lower ribs (4) as the bottom presser piece and the outer presser piece, and the upper edge is an intermediate ring It is a form connected to the lower edge surface of (3).

A hinge-shaped groove (7b) is provided at a position close to the outer edge of the bottom disk (5) provided on the bottom presser piece (7), and the edge (6a) of the bottom presser piece (6) separated by one is provided. When a hook-shaped groove (6b) for hinges is provided at a close position and a bar-like pole at the center of the upper surface of the bottom disk (5) is pulled upward, the bottom presser piece (6) is moved when the bottom disk (5) moves upward. ) Of the hinge-shaped groove (6b) located in the position close to the edge (6a) of the hinge), the outer presser piece (8) is curved downward in advance, and the bottom presser piece (7) has a bottom disk ( The external presser piece (9) is bent downward from the groove portion (7b) for the hinge provided at a position close to the outer edge of 5). This function and structure is such that the external presser piece (8) (9) is shaped like a flower bud, and the neck length of the inner diameter of the mouth of the container passes through a sufficient gap and is pulled upward. When the stick-shaped pole is released, the outer presser pieces (8) and (9), which have been constricted by the restoring force of the plurality of elastic lower ribs (4) of the bottom presser piece and the outer presser piece, spread the umbrella. There is an effect that the tablet can be pressed without any wrinkle by expanding in a horizontal plane so as to cover the upper surface of the tablet by operation.

Since the outer presser piece (8) is curved in advance from the center position of the mountain-shaped groove (6b) for hinges provided on the one-piece bottom presser piece (6), the top of the bottom presser piece (6) is hinged. The triangular reinforcing rib (14) provided on the outer circumferential surface of the cylindrical pole (11) from the center position of the mountain-shaped groove (6b) is bent when the bottom presser piece (6) rises upward. The outer presser piece (8) is effectively refracted and bent in advance, preventing deformation.

The upper ring-shaped inner plug (1) is formed so as to be lightly fitted to the inner diameter of the container when the cushioning material of the present invention is accommodated in the container, and the upper part of the cylindrical pole (11) A plurality of rectangular ribs (12) from the edge surface have an effect of assisting the pressing of the center portion of the tablet cushioning material by contacting the back surface of the cap when the cap is screwed onto the container.
When taking out the cushioning material for tablets, the external presser pieces can be easily taken out by holding the tip of the rod-shaped pole (13) provided on the upper part of the bottom disk with a finger and pulling it upward. If an undercut is provided on the inner surface of the upper ring-shaped inner plug (1), the upper ring-shaped inner plug (1) can be easily taken out by pulling up.

In order to allow the conventional external presser piece to pass through the inner diameter of the container, it contacts the upper surface of the mouth and curves upward, so that the width of the multiple external presser pieces touch each other and its outer shape is smaller than the inner diameter of the mouth. It is formed. Therefore, the dimension value of the slit separating the external pressing piece is also limited, and cannot be used in the case of a tablet having a small shape.

The tablet cushioning material of the present invention is shaped like a flower bud before inserting the plurality of external presser pieces (8) and (9) as described above, and passes through the mouth inner diameter of the container. Sometimes it does not come into contact with the inner diameter of the mouth or the upper surface of the mouth and passes through a sufficient gap through the mouth inner diameter of the container so that it is not numerically regulated with respect to the width of multiple external pressing pieces and the width of the slit without any influence. Can be flexibly and flexibly adapted to changes in the size and shape of tablets, changes in the inner diameter of the mouth and body of the container, and changes in the amount of space in the upper part of the container due to the amount of tablet filling. It is a tablet cushioning material with epoch-making features that has a remarkable effect.

Embodiments of the present invention will be described in detail with reference to the drawings.

1 to 8 relate to a first embodiment of the cushioning material for tablets of the present invention, FIG. 1 is a sectional view taken along the line E in FIG. 2, and FIG. 2 is a bottom surface of the cushioning material in FIG. It is a figure which shows the position of the groove part (6b) (7b) of the mountain shape for hinges formed in the bottom part presser piece (6) (7) connected with the external presser piece (8) (9) in the figure. FIG. 3 is a plan view of the cushioning material of FIG. 1, and the position of the triangular reinforcing rib (14) of the bottom pressing piece (6) connected to the outer pressing piece (8) and the rectangular rib (12). FIG. 4 is a cross-sectional view showing the operation of each part when the cushioning material is inserted. FIG. 5 is a front view showing the appearance of the cushioning material. FIG. 6 is an external view when the cushioning material is inserted. FIG. 7 is an external front view showing a state in which the cushioning material is inserted into the container. FIG. 8 is a sectional view showing a state in which the cushioning material is mounted in the container.

As shown in FIGS. 1 and 2, the symbol A indicates a cushioning material according to the present invention, which is integrally formed of a synthetic resin material having appropriate elasticity.
The buffer material A has a plurality of, for example, four upper vertical ribs (2) connected at equal intervals from the lower inner diameter of the upper ring-shaped inner plug (1) to the upper edge surface of the intermediate ring (3). A plurality of, for example, twelve bottom pressing pieces in the radial direction across the slit (10) from the outer edge of the bottom disk (5) and the edges (6a) (7a) of (6) (7), for example, twelve The base portions (8a) and (9a) of the external presser pieces (8) and (9) and the upper edge of, for example, twelve elastic lower ribs (4) are connected to the lower edge surface of the intermediate ring (3) to be integrated. Formed

Thus, when the cushion ring A is inserted into the upper surface of the tablet C in the container B, the upper ring-shaped inner plug (1) has, for example, four upper vertical ribs (2) and, for example, twelve elastic lower portions. When the rib (4) is pressed and elastically curved upward, the inner diameter of the mouth and the upper ring-shaped inner plug (1) are light so that the upper ring-shaped inner plug (1) does not rise from the upper surface of the mouth of the container. It is formed to fit.

For example, six bottom presser pieces (7) are provided with a mountain-shaped groove (7b) for hinges at a position close to the outer edge of the bottom disk (5), and are separated from each other, for example, six bottom portions. The presser piece (6) is provided with a mountain-shaped groove (6b) for hinges at a position close to the edge (6a), and a bar-shaped pole (13) is formed at the center of the upper surface of the bottom disk (5). When the rod-like pole (13) is pulled upward, the bottom disk (5) rises and bends from the angled groove (6b) for the hinge provided on the bottom presser piece (6). (6a) is pulled obliquely upward, and the external presser piece (8) is bent in advance. The external presser piece (9) is refracted from the hinge-shaped groove (7b) provided on the bottom presser piece (7), but the outer presser piece (9) has a longer distance from the edge (7a). Bends late.
The timing of the movement of the external presser pieces (8) and (9) with a time difference is important for the external presser piece (9) to bend and constrict so that the flower folds overlap the outside of the external presser piece (8). It is a factor.

The position of the triangular reinforcing rib (14) of the bottom holding piece (6) connected to the external holding piece (8) in the plan view of the tablet cushioning material A shown in FIG. It is a figure which shows several positions of 12).
As shown in FIG. 4, the cushioning material A for tablets is formed on the cylindrical pole (11) formed on the upper surface of the bottom disk (5). A triangular reinforcing rib (14) is formed at the center of (6b), and a plurality of, for example, three rectangular rectangular ribs (12) divided from the upper edge of the cylindrical pole (11). Are connected to each other, and a bar-shaped pole (13) is integrally formed at the center, and the operating shape of each part when the bottom disk (5) and the bottom presser pieces (6) (7) are raised. Refracted in an inclined direction with the hinge-shaped groove (6b) adjacent to the edge (6a) of the bottom presser piece (6) connected to the outer presser piece (8) as a fulcrum. The base part (8a) and the lower rib (4) of the outer presser piece (8) are drawn toward the upper center part, and the outer presser piece ( ) Is curved in advance.

The bottom presser piece (7) connected to the external presser piece (9) is refracted in the inclined direction with the groove portion (7b) for the hinge as a fulcrum at a position close to the outer edge of the bottom disc (5). The base portion (9a) and the lower rib (4) of the presser piece (9) are drawn toward the upper center, and the external presser piece (9) is delayed and curved outward from the external presser piece (8).

The form of the operation function of the preceding and slow movement of the external presser piece is based on the respective edge portions (6a) and (7a) of the base portions (8a) and (9a) of the external presser pieces (8) and (9). When the distance between the central portions of the groove portions (6b) and (7b) for the hinges as the fulcrum is long and short and the bottom presser pieces (6) and (7) are raised in the same manner as the bottom disc (5), The distance from the base point of the edge (6a) of the bottom presser piece (6) connected to the presser piece (8) to the fulcrum of the center part of the groove portion (6b) of the hinge chevron is short, and the external presser piece (9) The distance from the base point of the edge (7a) of the connected bottom presser piece (7) to the central fulcrum of the groove portion (7b) of the hinge chevron is formed long, and the difference in length is that of the external presser piece (8 ) And (9), the external presser piece (8), which has been operated in advance and slowed down, is bent inwardly, Hold pieces (9) is a shape that Lisbon curved to wrap the outside.
In particular, the external presser pieces (8) and (9) are overlapped with each other so that they are curved and constricted like flower buds, which are not yet present in conventional tablet cushioning materials. Will provide a breakthrough to the market.

FIG. 5 shows a front view of the outer appearance of the tablet cushioning material, and is a diagram showing in detail the shape of the external presser piece and the like in a concrete three-dimensional shape. The external presser pieces (8) and (9) show the form until the tablet cushioning material is inserted into the container, and are external views showing a developed view in a substantially horizontal shape of the same shape.

FIG. 6 shows a front view of the external appearance of the tablet cushioning material. The bar-shaped pole (12) is pulled upward to curve the external presser pieces (8) and (9). It is a figure which shows the external appearance shape which makes an inner side and external presser piece (9) curves outside, and a petal is narrowed. Since the petal-squeezing shape can be actuated, the external presser piece has a large width and the external presser piece has a large width even when the inner diameter of the container and the tablet filling amount are large and the space from the upper surface of the tablet to the upper surface of the tablet is small. If the plurality of pressing pieces are even numbers, for example, 24, 18, 16, 12, 8, 6, etc., the minimum number can be six. Also, the slit width can be made as small as possible depending on the minimum dimensions, for example, the mold structure, material and strength, and wear resistance. The normal size of 0.5 mm is possible, which means that the cushioning material can be designed without the outer pressing piece being restricted by the inner diameter of the container.

FIG. 7 is a diagram showing an external view of insertion into a tablet cushioning material container and the insertion of the tablet cushioning material A of the present invention into the space between the upper surface of the tablet C and a cross section of the container B. The movement of the trajectory that expands from the form in which the external presser piece is curved and squeezes is released when the tablet cushioning material releases the rod-like pole (13) in the state shown in the figure, and the external presser piece is bent and squeezed. Then, the lower rib (4) expands downward in an umbrella shape from the curved shape like a bow with an elastic restoring force and presses to cover the upper surface of the tablet. This unfolding trajectory motion can be used more effectively even if the space from the top surface of the tablet to the top surface of the mouth is large as before.

FIG. 8 is a view in which the cushioning material A for tablets is inserted into the container B and the upper surface of the tablet C is pressed without any damage to close the cap. From the upper edge of the cylindrical pole (11) formed on the upper surface of the bottom disc (5) at the center of the tablet cushioning material, for example, three rectangular ribs (12) divided into three equal parts and the center It is a figure which shows mounting | wearing of the cushioning material for tablets provided with the structure and the function which can respond also to the inertial impact of a container, when the rod-shaped pole (13) of this contacts the inner packing lower surface of a cap, and it respond | corresponds.

The tablet cushioning material A1 of the second embodiment shown in FIG. 9 shows a form corresponding to the container B1 in which the inner diameter of the container B and the container B1 are the same and the inner diameter of the cylinder is smaller than the container B. The presser piece is configured to be easily elastically deformed by a plurality of angled grooves.
As shown in FIG. 10, the cushioning material A1 for tablets is inserted into the container B1, and the tip presser piece of the outer presser piece is easily bent by a plurality of chevron-shaped grooves and comes into contact with the inner wall surface of the body part along the downward direction. I can do it.

Since the cushioning material A for tablets of the present invention has a function and a structure in which the external pressing piece is bent downward and is narrowed when inserted into the container, the inner diameter of the mouth is not limited even when the inner diameter of the container is small. Since it is a shape that does not interfere with the inner wall of the neck, a flexible shape that has universal validity with respect to the inner diameter of the mouth of the target container to be used can be expanded.

The cushioning material A for tablets of the present invention has a function and a structure that allow easy insertion and removal of containers. The main feature is that the external pressing piece is curved and constricted, and has a shape and function that could not be achieved with conventional tablet cushioning materials.

Although the embodiment and examples of the present invention have been described, the scope of the present invention is not limited thereto. For example, the shape of a picking shape or a rod-shaped pole for taking out the buffer material for the tablet is the situation. Of course, it can be carried out with appropriate changes within a range that has effects.

The present invention manufactures and sells innovative products that are not yet available in conventional cushioning materials, such as pharmaceutical tablet containers, health and health tablet containers, and the contents of general tablet containers. It can be used for universal expansion.
