DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tablet container filling for inserting a tablet into a space above a container to prevent the tablet from moving in the container.

[0002]

2. Description of the Related Art Conventionally, a synthetic resin film is rolled and packed in an upper space in a container to prevent chipping or cracking due to collision of tablets in the container during shipping and transportation. In the above case,
When removing the film, if the caliber of the container is small, the film cannot be picked out, and the film is pulled out while pressing the film against the inner surface of the container with fingers. However, there is a problem that the film slips and is difficult to remove.

[0003] Therefore, the applicant has previously proposed a substantially tubular flexible filling having a net-like shape, one end closed, and the other end open (Japanese Utility Model Publication No. 5-7151). Since the stitches can be freely expanded and contracted due to the bias of the stitch, even if the outer diameter of the filling is large or small with respect to the diameter of the container (6), it can be inserted. Therefore, it has an advantage that it can be used for a plurality of types of containers having different sizes, and that it can be easily taken out from the container.

[0004]

The production of injection-molded cylindrical stuffing requires a complicated mold, and it is practically impossible to produce stuffing of the required size at low cost. Extremely difficult. The operation of filling the tablets into the container (6) is automated, and if the filling of the stuffing cannot be automated following this operation, the productivity will not increase. The generally considered automatic filling of the filling is to stack the fillings, stock them, remove them one by one from the top or bottom filling by suction and push them into the mouth of the waiting container. However, it is not possible to take out one by one with the filling of the mesh body by suction. The present invention is directed to a tablet container filling that can be produced by injection molding and that can be easily filled into containers automatically.

[0005]

The filling of the tablet container (6) of the present invention is inserted into an upper space in the container (6) containing tablets,
In a filling for preventing the tablet from moving in the container (6), the tablet is integrally formed into a substantially bowl-like shape with a flexible synthetic resin.
(1) Except for the center, the portion has a substantially net shape, the bottom (1) has an outward projection (2) at the center, and the peripheral wall (3) gradually increases in diameter toward the opening side. It is stored in the container (6) in a state.

More specifically, the mesh portion has a longitudinal axis (4) extending radially from the bottom (1) to the opening edge and an adjacent longitudinal axis (4) (4).
It is composed of a plurality of connecting pieces (5) connecting between them, and the connecting pieces (5), (5), (5) adjacent in the circumferential direction are arranged in a staggered manner.

[0007]

Since the filling is formed in a bowl shape and the peripheral wall (3) has a gradually increasing diameter at the opening side, it can be formed by injection molding of a resin with a mold having a simple structure of a split structure.

When filling the stuffing container (6), the bowl-shaped stuffing is stacked in a face-down state. The outer diameter of the mouth (61) of the container (6) for filling the filling is set to a size that can enter the bowl-shaped filling into a state where there is room. The center of the bottom of the uppermost stuffing of the stacked stuffing is sucked by the suction tool (7) and taken out upward, and the stuffing is put on the opening (61) of the container (6) on standby while maintaining the posture as it is.

An outward projection (2) on the bottom (1) of the bowl-shaped filling.
Is provided, and the peripheral wall (3) of the filling gradually expands toward the opening side. Therefore, when the fillings are stacked and stocked, a gap is formed between the upper and lower fillings, and the entire upper and lower fillings are formed. Since it is possible to avoid close contact and overlap, when the uppermost stuffing is adsorbed, the stuffing below it does not lift together.

Since the peripheral wall (3) of the bowl-shaped filling gradually expands toward the opening side, the opening of the container (6) is opened by the suction device (7).
When the padding is placed on (61), even if there is some misalignment, the inner surface of the peripheral wall (3) slides along the opening edge of the container (6),
The mouth (61) of (6) is guided to the bottom (1) of the stuffing, so that the stuffing can be put on the mouth (61) of the container (6) in the correct posture.

In addition, since the height of the stack with respect to the quantity of the stuffed products becomes constant due to the presence of the projections (2),
The fillings are stacked on a table that automatically rises in conjunction with the operation of the suction device (7), and the height of the top stuffing is ensured to correspond to the bottom dead center height of the suction device (7). be able to.
As a result, the top stuffing does not reach the bottom dead center height of the suction tool (7), causing a removal error, or the height position of the top stuffing is higher than the height of the suction tool (7). As a result, it is possible to prevent the suction device (7) from crushing the stuffing.

The container (6) is taken out by the suction device (7), and
The bottom (1) of the padding (61) is pushed into the container (6) by lowering the suction tool (7). A peripheral wall (3) contiguous with the bottom (1) of the filling fills the opening edge of the container mouth (61) and the inner surface of the mouth (61) by the bottom (1) pushed into the mouth (61) of the container (6). It is slid and dragged into the container (6), and the padding fits inside the container (6) with the inside and outside turned upside down. The suction of the suction tool (7) is released, the suction tool (7) is raised, and the filling of the container (6) with the filling is completed.

To remove the filling, the mouth (61) of the container (6)
When the finger is inserted into the container and the finger is lifted while pressing the inner surface of the peripheral wall (3) of the stuffing, the stuffing is slid together with the inner surface of the container (6), and the stuffing can be easily taken out.

A mesh portion of the filling is formed by a longitudinal axis (4) extending radially from the bottom (1) to the opening edge and a plurality of connecting pieces (5) connecting the adjacent longitudinal axes (4) and (4). If the connecting pieces (5) that are adjacent in the circumferential direction are arranged in a staggered manner, the degree of freedom in the radial direction of the peripheral wall (3) is large, and the padding can be easily turned inside out. If the connecting pieces (5) between the vertical axes (4) and (4) are connected in a line in the circumferential direction, the diameter of the peripheral wall (3) can hardly be increased, so that the opening (61) When the bottom of the padding is pushed into the container (6), the peripheral wall (3) does not expand in diameter and the pushing resistance increases.
The connecting piece (5) between the vertical axes (4) and (4) of (3) is broken.

Since the opening edge side of the peripheral wall (3) is enlarged,
When the filling is dragged into the container (6), it is more easily turned over.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a state in which a bowl-shaped filling is laid down, and FIG. 2 is a plan view thereof. The filling is integrally molded by injection molding of a low-density polyethylene resin, and the bottom (1) is closed circularly except for the outer periphery,
A protruding frustoconical projection (2) is formed at the center of the closing portion (11),
A rib (21) is provided radially on the inner surface of the projection (2).

The outer peripheral portion of the bottom portion (1) of the padding and the peripheral wall (3) connected to the outer peripheral portion have a longitudinal axis (4) extending radially from the closing portion (11) and a longitudinal axis (4) adjacent thereto. 4) (4) Connecting piece connecting between
(5) is formed in a substantially net shape. A pair of adjacent longitudinal axes (4) and (4) are connected by a plurality of connecting pieces (5), and the connecting pieces (5) and (5) adjacent in the circumferential direction are not continuous and are arranged in a staggered manner. Have been.

The peripheral wall (3) of the filling gradually expands toward the edge of the opening, and the tip of the longitudinal axis (4) is bent outward so as to be parallel to the opening. A bulge portion (31) that bulges round toward the bottom (1) side is formed.

As shown in FIG. 3, the mesh portion of the padding is such that it does not become undercut with respect to the injection mold halves or that it can be easily separated from the mold by elastic deformation of the resin. It is undercut. This is a technique in which the peripheral wall (3) of the filling gradually expands toward the opening.

The mouth (61) of the container (6) for filling the above-mentioned filling material.
Has an inner diameter larger than the circular closing portion (11) of the bottom (1) of the filling, and an outer diameter covering the marginal wall (3) of the filling.

The step of filling the container 6 with the filling will now be described. As shown in FIG. 5A, a predetermined amount of tablets (8) is pre-filled in a container (6), and an upper part of the container (6) has a space for filling. The stuffing
As shown in Fig. 6, automatic lifting platform
(9) Set on top. Each time the uppermost filling is taken out, the automatic elevating platform (9) rises by that amount to keep the height of the uppermost stack constant.

The center of the bottom of the uppermost stuffing on the elevating table (9) is sucked by the suction tool (7) and taken out upward, and while maintaining this posture, it is inserted into the opening (61) of the waiting container (6). Cover with filling (FIG. 5A). Lower the suction device (7) and lower the filling (1)
Is pushed into the container (6) (FIG. 5B). A peripheral wall (3) continuous to the bottom of the filling is slid over the opening edge of the container (6) and the inner surface of the mouth by the bottom pressed into the mouth of the container (6).
The padding is dragged into the container (6), and the stuffing is accommodated in the container (6) with the inside and outside turned upside down.

The suction of the suction tool (7) is released, and the suction tool (7) is released.
To complete the filling of the container (6) with the filling (FIG. 5C).

To remove the filling, insert the finger F into the mouth (61) of the containers (6) and (6) as shown by the two-dot chain line in FIG. 5C.
When the finger F is pulled up while pressing the inner surface of the peripheral wall (3) of the stuffing, the stuffing is pulled up together with the inner surface of the container (6) and can be easily taken out. If the bulge (31) is formed at the tip of the longitudinal axis (4) of the peripheral wall (3) of the stuffing as in the embodiment, the finger F is hooked on the bulge (31) and the stuffing is more easily taken out. it can.

In carrying out the present invention, the mesh portion of the padding is formed like a grid in the bias direction (the peripheral wall (3)).
Since the opening side is enlarged, each stitch does not become a square.) The diameter may be expandable in the circumferential direction.

The configuration of the above embodiment is not limited, and various modifications are possible within the scope of the claims.
