Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a cushioning material for tablets that is used by filling the upper part of a container containing tablets such as pharmaceuticals and food products. This invention relates to a cushioning material for tablets made of synthetic resin suitable for wide-mouthed bottles.

<Prior art and problems to be solved> Generally, in a container containing a large number of capsules or tablets, in order to prevent the tablets from being damaged due to collisions between the tablets or the walls of the container due to vibration etc. ,
Cushioning materials such as urethane foam, cellophane, and cotton are stored at the top of the container, but such cushioning materials are difficult to manage and store hygienically, and dust tends to adhere to them during the filling process. There are drawbacks such as hygienic issues and the filling process is time-consuming.

From this point of view, the applicant first proposed the
In No. 39265, we proposed a cylindrical cushioning material integrally molded with synthetic resin material. According to this proposal, the cushioning properties of a disc-shaped cushioning material main body 1 having a large number of notches in the radial direction, and a plurality of upright pillars 3 are provided.
Although it has an excellent effect in compressing the upper surface of the tablet in the container 5 due to its elasticity, it actually has the following problems. First, since the central portion of the bottom plate of this cushioning material is formed of a solid disk, it has poor elasticity, and there is a large difference in elasticity compared to the soft elasticity of the surrounding radial presser pieces. Therefore, it is unrivaled in terms of effectively and uniformly compressing the uneven surfaces of a large number of granular tablets, especially the entire area of the tablet surface in a wide mouth bottle with a wide diameter and body. It is unsuitable for tablets that are relatively soft and break easily.

Therefore, the present invention has a structure that can be easily manufactured by integral molding, but it can effectively compress the uneven tablet surface over a wide area in a wide-mouth bottle without leaking, and it is also easy to put in and take out the bottle. The main object of this invention is to provide a synthetic resin cushioning material that has functions that are easy to perform and also has an outer lid function.

<Means for solving the problem> In order to achieve the above object, the present invention is made by integrally molding a synthetic resin material with appropriate elasticity,
It consists of a cylindrical body part 1 and a number of leg rods 2 arranged in a cylindrical shape in series at the lower end of this body part.
The leg rods are erected concentrically through slits 3 at appropriate intervals in the circumferential direction, and the middle portions of the plurality of leg rods 2 arranged in a cylindrical shape are axially aligned so that they have a small diameter. This narrowest diameter portion 2a
A horizontal internal presser piece 4 extending in the axial direction is formed on the inner surface of the leg rod 2, and a lower portion of the leg rod 2 from the narrow diameter portion 2a is inclined outward to form an external presser piece 5. This external presser piece 5 is formed within a range that does not exceed the circumference of the body,
Furthermore, the base portions 5a, 4a of the outer presser piece 5 and the inner presser piece 4 are formed thin or thin so that the outer presser piece 5 and the inner presser piece 4 can be easily elastically deformed, and furthermore, A large-diameter lid 6 is integrally formed at the upper end of a cylindrical body 1.

<Function> The above-mentioned buffering material A acts as a buffering material for the tablets C stored in the container B by filling it into a container containing a large number of tablets C, especially a wide-mouthed bottle B having a wide diameter and body. It essentially acts as a stopper.

<Example> Embodiments of the present invention will be described below with reference to the drawings.

In the figure, reference numeral A indicates a cushioning material according to the present invention, which is integrally molded from a synthetic resin material having appropriate elasticity. This buffer material A
consists of a cylindrical body 1 and a number of cylindrical leg rods 2 arranged in series at the lower end of the body. The leg rods 2 are erected concentrically through slits 3 at appropriate intervals in the circumferential direction. The intermediate portions 2a of the numerous leg rods 2 arranged in a cylindrical shape are narrowed in the axial direction to have a small diameter, and extend toward the axial direction on the inner surface of this narrowest diameter portion. A horizontal internal presser piece 4 is formed. Further, a portion below the narrowest diameter portion 2a of the leg rod is inclined outward to form an external presser piece 5. This external presser piece 5
The outer diameter is within a range that does not exceed the circumference of the body 1,
Preferably, the outer diameter of the external presser piece 5 is approximately equal to the outer diameter of the body portion 1. Further, the base portions 5a, 4a of the outer presser piece 5 and the inner presser piece 4 are formed thin or thin so that the outer presser piece can easily be elastically deformed in the vertical direction.

Further, a large-diameter lid body 6, which constitutes a substantial stopper of the container b, is integrally formed at the upper end of the cylindrical body portion 1.

The buffer material A constructed as described above is used by being filled into a container containing a large number of tablets C, particularly a wide mouth bottle B having a wide diameter and body. The container B may be a wide-mouth glass or plastic bottle, an aluminum can, or a cylindrical container.

Therefore, when inserting the cushioning material A into the wide-mouthed bottle B, the external presser piece 5 is formed within a range that does not exceed the circumference of the body 1 when viewed from above, so that the buffer material A is not obstructed by the outer presser piece 5. It can be easily inserted into the mouth of the container without having to worry about it. When the cushioning material A is pushed into the container, the external presser piece 5 comes into contact with the surface of the tablet and the thin base portion 5
a to expand its pressing area and elastically press the tablet surface together with the internal pressing piece 4. At this time, since the inner and outer presser pieces 4 and 5 are formed independently with the slit in between, they are elastically deformed to adapt to the uneven surface of the tablet, as shown in Fig. 2, and the tablet surface is completely and uniformly formed. can be pushed to Furthermore, since the lid 6 is integrally formed, the container can be sealed at the same time as the cushioning material A is stored, thereby streamlining the packing operation.

Although typical embodiments of the present invention have been described above, the present invention is not necessarily limited to the structure of the above-described embodiments.
It goes without saying that the present invention can be implemented with appropriate changes within the scope of the effect.

<Effects of the Invention> The present invention has the following effects by being configured as described above.

Since the external presser piece 5 is formed within a range that does not exceed the circumference of the body 1 when viewed from above, when inserting the cushioning material A into the bottle B, it can be easily inserted without being hindered by the external presser piece 5. It can be inserted into the mouth of the container, and when the cushioning material A is pushed into the container, the external presser piece 5 comes into contact with the surface of the tablet and is pushed up via the thin base portion 5a, increasing the pressing area against the tablet. is spread out, which allows it to press against the tablet surface over a wide area.

Since the external presser piece 5 is formed to be inclined downward and outward, when it is filled into a bottle, it comes into contact with the surface of the tablet and is pushed upward to a substantially horizontal position, and its elastic repulsive force provides a sufficient pressing force. is obtained.

The inner and outer presser pieces 4 and 5 are formed independently with a slit in between, and have thin or narrow base portions 4a and 5a, so that they can easily be elastically deformed to adapt to the uneven surface of the tablet. This allows the surface of the tablet to be pressed substantially uniformly and effectively without any leakage, thereby preventing breakage of relatively soft tablets even when stored.

Furthermore, since the lid 6 is integrally formed on the upper end of the body 1, the container can be sealed at the same time as the cushioning material A is attached, and the attachment of an outer lid can be omitted, streamlining the packing work. be able to. Moreover, the upper end of the cushioning material A itself is closed by the outer cover 6, and the entire lower surface is covered with inner and outer pressing pieces 4,
5 is formed and the inside is sealed, it is convenient because the desiccant can be stored in the internal middle part by pushing up the internal presser piece 4.
