By the way, a conventional lid for a viscous material container has an outer peripheral portion of the inner lid which is in sliding contact with the peripheral wall surface of the container body, and is constituted by an annular sliding contact piece extending in one direction from a face plate portion. The entire surface of the container is in sliding contact with the peripheral wall surface of the container body.

For this reason, in the conventional inner lid of the viscous material container, if the gap size between the inner lid and the peripheral wall surface of the container body is set to be small, the sliding resistance of the inner lid is large and the usability is poor. However, if the gap size is set to be large, there is a problem that the viscous material leaks from the gap. Therefore, in manufacturing the viscous material container and the inner lid, it was necessary to improve the dimensional accuracy.

In view of the problems of the conventional inner lid of the viscous material container, the present invention increases the sliding resistance of the inner lid or leaks the viscous material from a gap without increasing the dimensional accuracy. An object of the present invention is to provide an inner lid body for a viscous material container capable of solving the above problem.

In order to achieve the above object, the inner lid of the container for viscous material of the present invention, the peripheral wall surface of the container body for containing the viscous material of the container for viscous material, the outer peripheral portion is provided so as to slide contact, In an inner lid body having a discharge port for extruding a viscous material on a face plate portion, an outer peripheral portion of the inner lid body is formed by an annular sliding contact piece that extends in both directions in an arc shape with the face plate portion interposed therebetween. It is characterized in that the tip portion of the piece is in sliding contact with the peripheral wall surface of the container body.

In this case, a notch can be formed in one of the sliding contact pieces.

Further, of the sliding contact pieces, the position of the tip of the sliding contact piece on the bottom surface side of the container body and the position of the bottom surface of the face plate portion are set to the same level, and the outer peripheral portion of the face plate portion is annular. It is possible to connect to the intermediate position of an annular sliding contact piece that extends in an arc shape in both directions with the rib sandwiched therebetween.

According to the inner lid of the container for a viscous material of the present invention, the outer peripheral portion of the inner lid is composed of an annular sliding contact piece that extends in an arc shape in both directions with the face plate portion interposed therebetween, and a tip portion of the sliding contact piece is formed. Since it comes into sliding contact with the peripheral wall surface of the container body, compared with the conventional inner cover body for viscous materials in which the entire surface of the sliding contact piece slides with the peripheral wall surface of the container body, The dynamic resistance is reduced, the inner lid can be pushed down while finely adjusting the amount of viscous material to be pushed out from the discharge port with a light force from the finger, and the tip of the sliding contact piece Since it comes to be slidably in contact with the peripheral wall surface of the container body in a well-balanced manner, a gap is less likely to be formed between the inner lid and the peripheral wall surface of the container body, and the viscous material does not leak from the gap. In manufacturing the container for a dense material and the inner lid, it is not necessary to increase the dimensional accuracy, the manufacturing control can be facilitated, and the manufacturing cost can be reduced.

Further, by forming a notch in one of the sliding contact pieces, the sliding resistance of the inner cover can be further reduced, and at the time of manufacturing the inner cover, it is formed. It is possible to allow the sliding contact piece having the cutout portion of the inner lid body to be deformed, and to easily remove it from the molding die.

Further, of the sliding contact pieces, the position of the tip of the sliding contact piece on the bottom surface side of the container body and the position of the bottom surface of the face plate portion are set to the same level, and the outer peripheral portion of the face plate portion is annular. When the inner lid body is applied to a general container body having a flat bottom surface, the inner lid body is connected to an intermediate position of an annular sliding contact piece which extends in an arc shape in both directions with the rib sandwiched therebetween. The viscous material that remains between the face plate of the body and the bottom of the container body can be eliminated, and the viscous material can be used up to the end, and when the inner lid is pushed down, the inner lid deforms into strain. Can be prevented by the annular rib.

An example of the inner lid of the container for viscous material of the present invention is shown, (a) is a plan view, (b) is a partial cross-sectional front view, (c) is a bottom view, (d) and (e). ) Is an explanatory view of a discharge port. The inside lid of the container for viscous materials is shown, (a) is a front sectional view and (b) is a front sectional view showing a state of being attached to a container body.

Hereinafter, embodiments of the inner lid of the viscous material container of the present invention will be described with reference to the drawings.

1 to 2 show one embodiment of the inner lid of the viscous material container of the present invention.
The inner lid 1 of the container for viscous material is provided so that the outer peripheral portion 11 is in sliding contact with the peripheral wall surface 21 of the container body 2 for accommodating the viscous material of the container for viscous material. With a discharge port 13 through which a dense material is extruded, the outer peripheral portion 11 of the inner lid body 1 is composed of annular sliding contact pieces 11a and 11b that extend in an arc shape in both directions with the face plate portion 12 interposed therebetween. , 11b are brought into sliding contact with the peripheral wall surface 21 of the container body 2.

The inner lid 1 is molded using a relatively flexible synthetic resin material such as polyethylene resin, polypropylene resin, or polyamide resin, which is selected according to the properties of the viscous material contained in the container body 2. ..

The annular sliding contact pieces 11a and 11b that extend in an arc shape in both directions with the face plate portion 12 interposed therebetween are thinner than the face plate portion 12 in thickness, for example, are formed to have a thickness of about 0.2 to 0.5 mm. It deforms when it comes into sliding contact with the peripheral wall surface 21 of the main body 2 so as to be in close contact.

At the center of the face plate portion 12, a pressing portion 14 is formed so as to be able to uniformly push down the inner lid 1 when the viscous material is pushed out from the discharge port 13 and which is slightly bulged from the surroundings. ..

In the present embodiment, the discharge port 13 is formed at a position deviated from the central portion of the face plate portion 12 because the pressing portion 14 is formed in the central portion of the face plate portion 12. When the outer edge portion of 13 is used as the pressing portion, the discharge port 13 is formed in the central portion of the face plate portion 12.

The discharge port 13 can be formed as a simple opening, but in order to apply a load to the viscous material to be extruded, in addition to the cross-shaped cut as shown in this embodiment, FIGS. 1(d) and 1(e). It can be configured with a cut end as shown in.
When the scooping material extruded from the discharge port 13 is scooped with a finger, the wall thickness t of the discharge port 13 is thinner than the thickness of the face plate portion 12, for example, formed to be about 0.2 to 0.5 mm. It is transformed into a shape that makes it easier to scoop viscous material with your fingers.

In addition, as shown in FIG. 2B, one of the annular sliding contact pieces 11a and 11b extending in an arc shape in both directions with the face plate portion 12 sandwiched therebetween is used. The cutout portion 16 can be formed in the sliding contact piece 11a located on the opening side of the container body 2 when mounted on.
The notches 16 are formed at a plurality of locations at equal angular intervals, and in the present embodiment, four locations at 90-degree intervals.
As a result, the sliding resistance of the inner lid 1 can be further reduced, and at the time of manufacturing the inner lid 1, the sliding contact piece 11a having the cutout portion 16 of the molded inner lid 1 can be deformed. Therefore, it is possible to easily remove from the mold.

In addition, as shown in FIG. 2B, of the sliding contact pieces 11a and 11b, when the inner lid 1 is attached to the container body 2, the tip of the sliding contact piece 11b on the bottom surface 22 side of the container body 2 is attached. The position and the position of the bottom surface of the face plate portion 12 are set to the same level, and the outer peripheral portion of the face plate portion 12 is formed into an annular rib 15, and an annular sliding contact extending in an arc shape in both directions with the rib 15 sandwiched therebetween. The connection is made at an intermediate position between the pieces 11a and 11b.
Thus, when the inner lid body 1 is applied to a general container body 2 having a flat bottom surface 22, the viscous material remaining between the face plate portion 12 of the inner lid body 1 and the bottom surface 22 of the container body 2. In addition, the viscous material can be used up to the end, and the annular rib 15 can prevent the inner lid body 1 from being deformed into a strain when the inner lid body 1 is pushed down.

The inner lid body 1 for this viscous material container has a sliding contact with the inner lid body 1 as compared with a conventional inner lid body for a viscous material container in which the entire surface of the sliding contact piece is in sliding contact with the peripheral wall surface of the container body. The resistance is reduced, and the inner lid 1 can be pushed down while finely adjusting the amount of viscous material to be extruded from the discharge port 13 with a light force of a finger, and the sliding contact pieces 11a and 11b can be pushed down. The tip portion of the container comes into slidable contact with the peripheral wall surface 21 of the container body 2 in a well-balanced manner, and a gap is unlikely to be formed between the inner lid 1 and the peripheral wall surface 21 of the container body 2, and the viscous material leaks from the gap. Therefore, in manufacturing the viscous material container (container main body 2) and the inner lid body 1, it is not necessary to increase dimensional accuracy, manufacturing control can be facilitated, and manufacturing cost can be reduced. ..

Although the inner lid of the viscous material container of the present invention has been described above based on the examples thereof, the present invention is not limited to the configurations described in the above examples, and does not depart from the scope of the invention. In the above, the configuration can be appropriately changed.

The inner lid of the container for a viscous material of the present invention has a small sliding resistance of the inner lid, and a gap is unlikely to be formed between the inner lid and the peripheral wall surface of the container body. Since it does not leak out, it is not necessary to increase the dimensional accuracy when manufacturing a container for viscous material or an inner lid, which facilitates manufacturing control and reduces manufacturing costs. Therefore, it can be suitably used for the inner lid of various viscous material containers such as pharmaceuticals such as ointments, cosmetics such as creams, and industrial products such as pastes.
