Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a lid member for sealing a container opening when in use, mainly for preventing moisture absorption of contents in a container after opening the lid member, Used to prevent the scent from escaping out of the container.

[Conventional technology]

Conventionally, as shown in FIG. 8, a lid member that abuts on the upper end surface b of the opening of the container a in order to prevent the moisture contained in the container from being absorbed and the scent from escaping outside the container. On the inner surface of the upper end side of c, a cardboard of a size that closes the container opening
Was fitted tightly. When it is marketed as a product, the contents stored in the container are composed of a sealing member e made of aluminum or the like that seals the upper end of the container opening and a cardboard d of a lid member c that abuts the peripheral portion of the sealing member e. ,
Prevention of moisture absorption and escape of scent, and when the seal member e is broken, the thick paper d of the lid member c screwed or elastically attached to the container opening is directly pressed against the upper end of the container opening when used. As a result, it was possible to prevent moisture contained in the container from being absorbed and prevent the scent from escaping.

[Problems to be solved by the device]

As in the conventional case, when the cardboard d closely fitted to the inner surface of the upper end of the lid member c is used to prevent moisture absorption during use and to prevent the scent from escaping, the cardboard d has a size that closes the container opening. Since the thick paper d must be closely fitted to the inner surface of the upper end of the lid member c, the material cost of the thick paper d is not only required, but also the thick paper is punched into a predetermined size. Since it takes time and money to fit the lid member c at a predetermined position, the cardboard d
In the method of preventing moisture absorption and preventing the scent from leaking by using, there has been a disadvantage that the production cost is considerably high.

The present invention was made in view of these circumstances, and prevents the moisture absorption and scent of the contents stored in the container at the time of use by using the lid member installed at the time of selling the product upside down without using thick paper. It is an object of the present invention to provide a lid member for sealing a container opening in use, which can very easily prevent the escape of the container.

[Means for Solving the Problems]

In order to achieve the above object, according to the present invention, one end side of the lid member has an outer periphery (5, 10) of the container opening before opening the container.
A fitting part (2, 9) that is screwed or fitted into the container is formed, and the other end of the lid member is press-fitted into the container opening after the container is opened to maintain the sealed condition of the container contents. Protrusion (3,
3A, 3B) are formed, and the outer surface on the other end side is covered with an exterior seal member (7) before the container is opened.

[Action]

To prevent moisture absorption and scent escape when the product is sold on the market, aluminum foil or other sealing material that seals the upper end surface of the container opening is used to prevent the escape of the fragrance as in the conventional case. When the fitting protrusion provided on the upper end side is inserted into the container opening with the member upside down, the contents stored in the container at the time of use are protected from moisture absorption by the fitting protrusion that fits with the container opening. Prevents the escape of scent.

If the fitting protrusion of the lid member for sealing the container opening at the time of use is covered with a synthetic resin film or other exterior sealing member, dust may be attached to the outer surface of the fitting protrusion at the distribution stage, or Since there is no direct contact with the hand, the hygienic condition is kept good during use when the fitting protrusion is inserted into the container opening.

〔Example〕

The invention will be described based on the embodiments shown in the drawings. The invention is not limited to this.

FIG. 1 and FIG. 2 show an embodiment of the present invention, which is a lid member 1 having functions of preventing moisture absorption and scent escape.
However, this is a case where the present invention is applied to a container 4 made of glass, plastic, or the like, in which the male screw portion 5 is formed on the outer circumference of the opening.

Lid member 1 made of plastic or other material
Is a male screw part 5 provided at the outer periphery of the opening of the container 4 at one end.
A female screw portion 2 that is screwed with is formed, and at the other end side of the lid member 1, a fitting protrusion portion 3 that can seal the opening according to the opening shape of the container opening is formed.

The fitting protrusion 3 has a cylindrical shape, an inverted truncated cone shape, a polygonal column shape, an inverted polygonal pyramid trapezoidal shape, or any other shape depending on the shape of the container opening.

For example, powder such as instant coffee is stored in the containers 4 and sold in the market. To prevent moisture absorption and escape of aroma of the stored products at the time of marketing, aluminum that seals the upper end surface of the container opening is used. A sealing member 6 such as a foil is used, and a lid member 1 that is screwed onto the male screw portion 5 of the container 4 is mounted on the upper side thereof.

At the distribution stage of the product, the fitting protrusion 3 of the lid member 1
The outer surface on the side is covered with a synthetic resin film or other exterior sealing member 7, and dust is attached to the surface of the fitting protrusion 3 or a human hand handling the product directly contacts the surface of the fitting protrusion 3 at the time of shipping or marketing. Of the fitting protrusion 3 by removing the exterior seal member 7 at the time of use.
Even when the side is inserted into the container opening, good hygiene can be maintained.

The outer sealing member 7 covers the entire outer surface on the fitting protrusion 3 side with, for example, a bag-shaped heat-shrinkable synthetic resin film or the like, and the hot air is applied from the outside of the film. Can be performed by heat-shrinking and closely fitting to the fitting protrusion 3. In this case, the exterior seal member 7 does not necessarily have to be in the shape of a bag, and an opening that is slightly smaller than the upper end surface of the fitting protrusion 3 is provided in the bottom portion of the bag, and the upper end surface of the fitting protrusion 3 is provided. A heat-shrinkable exterior seal member having a paper sheet 8 formed in substantially the same shape as the upper end surface and having the outer peripheral portion of the paper sheet 8 and the side surface portion of the fitting protrusion 3 opened at the bottom portion. 7 and a paper sheet 8 by an exterior seal member 7 that shrinks by hot air,
You may make it coat | cover the outer surface of the fitting protrusion part 3 (FIG. 3). The paper sheet 8 in the above embodiment may be attached to the upper end surface of the fitting protrusion 3 instead of the tack label, and may be peeled off when fitting the fitting protrusion 3 into the opening of the container 4.

Next, the use of the lid member of this embodiment will be described.

FIG. 1 is a vertical cross-sectional view of a main part showing a state at the time of marketing in which a lid member 1 is screwed into an opening of a container 4 having various cross-sectional shapes. Instant coffee stored in the container 4 is shown. As for other products that do not want moisture or scent to escape, the aluminum foil or other sealing member 6 that seals the opening of the container prevents moisture absorption and scent escape as in the conventional case.

To take out the contents from the container 4, the lid member 1 screwed into the opening of the container 4 is rotated in the loosening direction to separate it from the container 4, and the sealing member 6 for sealing the upper end surface of the opening is sealed. It is done by removing.

When the instant coffee or the like was taken out of the container 4, the exterior sealing member 7 covering the outer surface of the lid member 1 was broken to expose the fitting protrusion 3 of the lid member 1, and the sealing member 6 was removed. As shown in FIG. 2, the fitting protrusion 3 of the lid member 1 whose top and bottom are turned upside down is inserted into the container opening.
Insert. This state is the normal appearance when the container 4 is used after being opened.

Since the fitting protrusion 3 of the lid member 1 is made so as to be able to seal the opening according to the opening shape of the container opening,
In a state of use in which the fitting protrusion 3 is inserted into the container opening, even if the insertion of the cardboard is omitted, the instant coffee and other moisture absorption and aroma are surely prevented from escaping.

Further, when using the lid member 1 of this configuration, in order to prevent moisture absorption and scent escape during use, it is possible to save the material cost by omitting the use of the conventionally used cardboard d, Since it is possible to save the labor and cost of pushing d into the position where it comes into contact with the upper end surface of the container opening, it is also useful for reducing the production cost of the lid member 1.

Moreover, in the lid member 1, the surface of the fitting protrusion 3 is covered with the exterior sealing member 7 at the stage of product distribution, so that dust may be attached to the surface of the fitting protrusion 3 at the time of shipping or marketing. Since the human hand handling the product does not come into direct contact with the product to prevent it from becoming unsanitary, it is possible to keep the lid member 1 in good hygienic condition during use.

Also in the case of the lid members 1A and 1B elastically fitted into the opening of the container 4A as in each of these embodiments, the lid members 1A and 1B with the cardboard d are used.
The same operational effects as those described in the first embodiment can be achieved without mounting the same on the first embodiment.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

After the lid member was once removed from the opening of the container, the lid member before opening the container was turned upside down and the fitting protrusion was press-fitted into the container opening, which was conventionally attached to the inner upper end surface of the lid member. Even if the cardboard is omitted, it is possible to prevent moisture absorption and scent of the container contents after opening from escaping. As described above, since the use of the cardboard can be omitted, not only the material cost required for the cardboard but also the labor and cost for mounting the cardboard and the inner upper end surface of the lid member can be saved.

Also, the outer surface of the other end of the lid member is covered with an exterior sealing member before opening the container, so that it is possible to prevent dust from adhering or touching human hands at the time of shipping or marketing the product. It is possible to maintain good hygiene.
