[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a filling material for a container used as a buffer material for preventing cracking, which is inserted on the tablet layer of a container containing tablets, capsules, etc. More specifically, it has good operability in loading into a container. The present invention relates to a cushioning material for a container.

[0002]

[Prior art]

 Tablets are generally stored in glass or plastic containers, but if the container during transportation or handling is subjected to vibration or shock, the tablets inside may break or chip. Therefore, conventionally, after the tablets are stored, one or several sheets of cushioning material for a container as a cushioning material are filled in the voids above the tablet layer to prevent the tablets from being damaged. . As the cushioning material used here, for example, a film made of polyethylene, polypropylene or the like can be cited, and normally, it is automatically filled in a rolled state by a poly sheet filling machine.

However, when the conventional cushioning material is pushed into the container by the poly sheet filling machine, the cushioning material tries to return to its original shape due to the impact resilience, so that it protrudes or pops out from the mouth of the container. It may happen. Such a phenomenon is likely to occur particularly in the case of a container having a wide mouth. When such a phenomenon is caused, there is a problem that when the cap is capped in the subsequent step, the cap bites the cushioning material, resulting in defective packaging.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems, and an object of the present invention is to provide a cushioning material for a container which has a good loading operability in the step of loading the cushioning material into the container.

[0005]

[Means for Solving the Problems]

 The cushioning material for a container of the present invention has a large number of folds formed by embossing on the surface of a flexible sheet material.

The flexible sheet material used for the cushioning material of the container of the present invention is a flexible synthetic resin sheet material, and specifically, a film made of polyethylene, polypropylene or the like is given. However, the present invention is not limited to this.

The fold line formed on the surface of the flexible sheet-like material is formed in a dent shape by an embossing process such as roller pressing. The folds may be linear or curved, but preferably the folds may be formed in a lattice shape.

The shape and number of folds may be appropriately set depending on the material and thickness of the flexible sheet material and the shape of the mouth of the container. Such folds can be formed, for example, by forming protrusions in a grid pattern on the peripheral surface of a flexible sheet-shaped material feeding roller of a poly sheet filling machine and feeding the flexible sheet-shaped material while pressing the roller. It is possible to form the flexible sheet material at the same time as it is transferred to the next step.

[0009]

[Action]

 The cushioning material of the present invention is loaded into a container that contains tablets and presses the uppermost surface of the contained tablet layer to regulate the movement of the tablets so that the tablets do not move due to vibration or shock, and damage is prevented. To prevent.

In addition, since the cushioning material of the present invention has a large number of creases formed on the surface thereof, the flexibility of the flexible sheet-like material is improved and the repulsion elasticity is reduced, so that the cushioning material is smooth in the container. It will be inserted into the container and will not pop out of the mouth of the container, thus providing good loading operability.

【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a plan view showing an embodiment of the cushioning material for a container of the present invention, and FIG. 2 is an enlarged sectional view of an essential part showing a section taken along line XX of FIG. In FIG. 2, the thickness direction is enlarged and the shape in the thickness direction is clearly shown. The container cushioning material 1 is made of a polyethylene sheet having a thickness of 30 μm, and has folds 2 formed by a roller press, which are formed by a roller press and are made up of lattice-shaped depressions with vertical intervals of 1.5 mm and widths of 1 mm. It has been subjected.

FIG. 3 is a sectional explanatory view showing an example of a usage state of the cushioning material for a container of the present invention. 4 and 5 are process explanatory views showing an example of a manufacturing process and a loading process of the container cushioning material of the present invention. The polyethylene film 11 is nipped by the feed roller 13 and the feed roller 14 and transferred to the next step. The feed roller 13 is provided with protrusions in a lattice shape on its peripheral surface. One side of the polyethylene film is embossed by the protrusions in a lattice shape, and the portion is depressed to form a lattice fold.

The polyethylene film 12 having the folds is cut into a predetermined length and rolled by the knocker 15 and the socket 16, and then the socket 16 is inverted as shown in FIGS. 5 (a) to 5 (c). Then, the container 5 containing a predetermined amount of tablets is forcibly pushed by the knocker 15 and loaded into the container 5.

Since the cushioning material loaded in the container is extremely flexible, it did not jump out or protrude from the mouth of the container due to its own resilience. Also, in the process of rolling a sheet-shaped object when inserting it into a container, it can be rolled much easier than conventional products, and its shape is stable, so insertion from the mouth of the container is extremely easy. there were.

[0016]

[Effect of device]

 Since the cushioning material for a container of the present invention has a large number of folds formed on its surface, it has a small impact resilience and can be smoothly inserted into the container, and after being inserted into the container, it pops out from the mouth of the container. There is no protrusion or protrusion, and the operability for loading the container is extremely good. Therefore, it is possible to prevent the occurrence of defective packaging containers.

The container cushioning material of the present invention can be easily manufactured by giving the fold forming action to the feed roller of the conventional poly sheet filling machine. The loading of the material can be carried out without preparing a buffer material having a crease in advance and without increasing the number of conventional steps.

What is stored in the container in the present invention is not limited to tablets, and may be, for example, powder, granules, agglomerates, agglomerates, etc. It can be applied to general-purpose containers.
