Description

[Detailed description of the invention]

[0001]

[Field to which the invention belongs]

 The present invention relates to a cushioning material that is inserted into an upper portion of a tablet container to suppress the movement of the tablet and prevent the tablet from cracking or chipping.

[0002]

[Prior art]

 If there is a space in the upper part of the container that contains tablets (in the present invention, capsules containing granules and powders are also included in the tablets), vibration or drop shock may cause collision between tablets or collision between tablets and container wall. Tablets crack or chip.

Therefore, as shown in FIGS. 4 and 5, a fitting portion (10) that tightly fits into the mouth portion (81) of the tablet container (8) and a reduced diameter portion (a diameter reduction portion that is continuous with the fitting portion ( 2) In the reduced diameter portion (2) of the tubular portion (1) having a plurality of slits (3) opened at the lower end, and flexible leg pieces (4) (4) are provided between the slits. A cushioning material has been proposed which is formed by projecting an inward pressing piece (5) at the lower end of each leg piece (4) and a downward pressing piece (51) extending obliquely downward to the outside (Patent Publication 4). No. 23817).

[0004]

[Problems to be solved by the device]

 Since the tip of the downward pressing piece (51) of the cushioning material is on a virtual circle that is approximately the same as the outer diameter of the tubular part (1), the cushioning material (7) is grabbed by an automatic machine and automatically loaded into the container. In doing so, the downward pressing piece (51) is caught on the opening edge of the mouth (81) of the container (8), and the caught part is extruded together with the leg pieces (4) to the outside of the container mouth and loaded. It became impossible and not only caused a loading error, but also caused a great deal of trouble as the cushioning material loading line stopped.

Further, the wall thickness of the leg piece (4) is smaller than the wall thickness of the fitting portion (10), but the length L ₂ is ₁ of the total length L ₁ of the tubular portion including the leg piece (4). It is less than / 2 and elastically deforms but lacks in softness. Therefore, in order to compensate for the small elastic deformation, a downward pressing piece (51) is provided in addition to the inward pressing piece (5), and the downward pressing piece (51) is elastically deformed outward to form a tablet group. It is designed to hold the entire upper surface of. Since the leg pieces (4) are less elastically deformed, the height from the upper end of the mouth (81) of the container (8) to the height of the upper surface of the tablet group must be increased. growing.

Furthermore, when inserting the cushioning material (7), if the tablet is a sugar-coated tablet, the tip corner portion (52) of the downward pressing piece (51) scratches the sugar-coated surface, and the sugar-coated layer is not applied to the bare tablet. In that case, there is a problem that the pressing piece (51) scrapes off the tablet surface or causes chipping. The present invention provides a cushioning material for a tablet container that can solve the above problems.

[0007]

[Means for solving the problem]

 The cushioning material (7) of the present invention is a tube having a fitting part (10) tightly fitted to the mouth part (81) of the tablet container (8) and a reduced diameter part (2) continuous with the fitting part. A plurality of slits (3) opened at the lower end are formed in the reduced diameter portion (2) of the portion (1), and flexible leg pieces (4) (4) are provided between the slits (3) (3). In the shock-absorbing material for a tablet container integrally formed of synthetic resin, which has a pressing piece at the lower end of each leg piece (4), the pressing piece is an inward pressing piece ( Only 5) is formed, and the length of the leg piece (4) is 1/2 or more of the total length of the tubular portion (1).

[0008]

[Action and effect]

 When the cushioning material (7) is inserted into the container (8), the lower end of the cushioning material (7) is fitted into the container mouth portion, and the diameter is gradually reduced from the fitting portion (10). The cushioning material (7) can be smoothly inserted even if the standby position of the is slightly displaced, and the downward pressing piece is caught on the rim of the container like the conventional cushioning material having the downward pressing piece, which may cause an insertion error and It is possible to prevent the resulting trouble.

When the cushioning material (7) is inserted into the container (8), the lower surface of the pressing piece (5) first comes into contact with the tablet, and the tablet is pressed by the elastic deformation of the leg pieces (4). As in (7), the corners of the diagonally downward pressing piece (51) can be prevented from damaging the tablet.

Since the leg piece (4) is longer than in the conventional case, the leg piece (4) is more likely to be elastically deformed, and the leg piece (4) is directly deformed by the bending of the leg piece (4) as well as the inward pressing piece (5). The tablet can be pressed against the tablet, and the tablet group can be effectively pressed without the conventional downward pressing piece (51). Further, since the leg piece (4) is long, that is, the flexible portion is long, it is possible to reduce the height from the upper end of the mouth portion (81) of the container (8) to the upper surface height of the tablet group, and the amount of stored tablets is the same. If so, the height can be made smaller than that of the conventional container (8). Since there is no conventional downward pressing piece for the cushioning material (7), the amount of resin material can be reduced accordingly and the cost can be reduced.

[0011]

[Embodiment of the invention]

As shown in FIG. 1, the cushioning material (7) has a lid (6) at the upper end of a tubular part (1) to be inserted into a container (8) and is integrally molded by injection molding of synthetic resin. ing. The tubular portion (1) is composed of a fitting portion (10) that tightly fits into the mouth portion (81) of the container (8) and a reduced diameter portion (2) whose lower portion gradually decreases in diameter. axial length L ₂ of the (2) accounts for 1 / 2-2 / 3 of the total length L ₁ of the cylindrical portion (1).

Slits (3) are provided at equal intervals in the circumferential direction over the entire length of the reduced diameter portion (2) in the axial direction, and the slits (3) are opened at the lower end of the reduced diameter portion (2) to provide slits ( Legs (4) are formed between (3) and (3). The wall thickness of the leg piece (4) is thinner than the wall thickness of the tubular portion (1). At the lower end of the leg piece (4), a pressing piece (5) is projected inward in a plane orthogonal to the axis of the tubular portion (1). Each pressing piece (5) has a narrow width on the tip side.

However, when the cushioning material (7) is inserted into the container (8), the lower end of the cushioning material (7) is gradually reduced in diameter from the fitting portion (10) fitted to the container mouth. Even if the standby position of the container (8) is slightly displaced, the cushioning material (7) can be smoothly inserted, and the downward pressing piece is caught on the rim of the container like the conventional cushioning material having the downward pressing piece. As a result, it is possible to prevent insertion errors and troubles resulting from them.

When inserting the cushioning material (7) into the container (8), the lower surface of the pressing piece (5) first comes into contact with the tablet, and the tablet is pressed by the elastic deformation of the leg pieces (4). As in (7), the corner of the downward pressing piece (51) can be prevented from damaging the tablet. Since the leg piece (4) is longer than before, it is more easily elastically deformed, and the leg piece (4) directly contacts the tablet due to the bending of the leg piece (4) as well as the inward pressing piece (5). The tablets can be pressed, and the tablet group can be effectively pressed without the conventional downward pressing piece (51).

Further, since the leg piece (4) is long, that is, the flexible portion is long, it is possible to reduce the height from the upper end of the mouth (81) of the container (8) to the upper surface height of the tablet group, and the amount of tablets to be stored. If it is the same, it can be made smaller than the conventional container (8). Since there is no conventional downward pressing piece for the cushioning material (7), the resin material can be reduced accordingly and the cost can be reduced. The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the utility model registration request.
