Description

[Detailed description of the invention] The present invention relates to a lid for a shaker or pouring container containing powder, granules, or liquid. Concerning lids of containers that can be taken out.

Conventionally, as shaker containers, there have been known containers in which a container body is provided with a lid body having a lid that can be freely opened and closed, such as those disclosed in Japanese Utility Model Publication No. 41-2140 and Japanese Utility Model Publication No. 41-23918.
Publication No. 42-25266, Special Publication No. 1977-
As seen in Japanese Patent Publication No. 9710, Japanese Patent Publication No. 50-2426, etc., the lid body is provided with an opening, and this opening is opened and closed by an opening/closing lid.

These containers have the advantage that they can be opened and closed with extremely simple operations, and the contents can be easily taken out.

However, since these containers have openings in advance, after the contents are contained, the entire container must be sealed from moisture by packaging material until it is delivered to the consumer. There is a drawback that a separate airtight lid must be prepared for field 1 where the contents are liquid.

Publication No. 33-18587, Publication No. 35-2898
As seen in Japanese Patent Application No. 7, etc., there are also known containers which have an opening/closing lid and have paper or film attached thereto, and the paper or film is cut off when used.

Although these containers are excellent in protecting the contents during transportation and storage depending on the material used, such as the film, the opening method is not necessarily easy or reliable, and some consumers do not want to be able to always obtain a constant opening. It's hard to say.

This invention does not cause leakage problems during transportation, storage, etc. even when containing liquid as contents, and has excellent preservability of contents, so it can be packaged with simple packaging materials, and when used, The present invention relates to a structure of a lid for a container that has advantages such as being able to take out the contents with a simple operation.

In other words, the present invention can be opened and closed freely by the bending part,
A container in which a film is adhered to the inner surface of a lid provided with an opening/closing piece having a tearing blade, except for the opening/closing piece, and the tearing blade comes into contact with the film and can tear a part of the film by pressing. The present invention provides a lid for a container, characterized in that the tearing blade contacts the film approximately perpendicularly, and the portion of the tearing blade that first contacts the film is at an acute angle.

The present invention will be explained in more detail below with reference to the drawings.

Fig. 1 is a plan view showing an example of a container using the container lid according to the present invention, Fig. 2 is a longitudinal sectional view taken along line A-A' in Fig. 1, and Fig. 3 is an enlarged bottom view of the opening/closing piece. , FIG. 4 is a side view, and FIG. 5 is a side view illustrating another shape of the blade of the opening/closing piece.

1 and 2, a container lid 1 according to the present invention can be opened and closed by a bent portion 2, and is provided with an on-off valve 4 having a tearing blade 3.

A film 5 is adhered to the inner surface of the lid 1 except for the opening/closing piece 4, and by pressing the tearing blade 3 against the film 5, the film 5 is torn and the contents inside the container 6 (not shown) are cut. do not have.

) can be easily taken out. The opening/closing piece 4 may be provided with a hook portion 7 if necessary.

The lid 1 can be molded all at once from synthetic resin.

The film 5 is easy to tear, has a content protection function, that is, has mechanical strength for transportation until it is torn, and is required to have the ability to prevent the content from deteriorating, so it is a combination of metal foil and synthetic resin. Sprayed films are preferred.

This film 5 is adhered to the inner surface of the lid 1 with the exception of the opening/closing piece 4 by an appropriate adhesive method.

The lid 1 according to the present invention can be combined with, for example, a cylindrical side wall material 8 and a bottom material 9 to form a container, as shown in FIG.

Although a cylindrical container is illustrated in the drawings, it is obvious that the shape may be a rectangular tube or any other arbitrary shape.

The feature of the lid 1 according to the present invention is that the tearing blade 3 contacts the film 5 approximately perpendicularly, and the portion 10 of the tearing blade 3 that first contacts the film 5 is at least at an acute angle. be.

Due to this structure, the film 5 is easily torn by pressing.

In addition, until you cut it open and take out the contents, use the ripper blade 3.
It is necessary to prevent the film 5 from coming into contact with the film 5, and depending on the case, it may be necessary to interpose an appropriate protective member.

As shown in FIG. 3, the tearing blade 3 is located on the back side of the opening/closing piece 4.
For example, it is provided in the shape shown in the figure, and the film 5 is torn off on approximately three sides by the tearing blade 3 so that one piece remains.

Figure 4 shows the opening/closing piece 4 shown in Figures 1 to 3.
It is an enlarged side view of
Preferably, the angle is between 20° and 60°.

FIGS. 5a and 5b are side views showing other shapes of the tearing blade 3 of the opening/closing piece 4, which may have an acute-angled portion 11 in addition to the portion 10 that comes into contact initially.

[Brief explanation of the drawing]

FIG. 1 is a plan view showing an example of a container using the container lid according to the present invention, FIG. 2 is a sectional view taken along line AA' in FIG. 1, FIG. The same figure is a side view, and FIG. 5 is a side view showing another shape of the blade of the opening/closing piece. The main symbols in the diagram are as follows.
