Abstract

<P>PROBLEM TO BE SOLVED: To provide a structure by which housed articles can be used in order from the oldest one in a container which can house small articles. <P>SOLUTION: This container is formed by attaching a first lid 2a and a second lid 2b having a structure which can be fitted on confronted opening sections of a cylindrical housing section body 1. Either one of the confronted opening sections is used for the putting in of an article, and the other opening section is used for the taking out of the article. Thus, the container which can perform so-called "first in first out" can be provided. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a container with a lid suitable for storing so-called small items, and more particularly, to a container with a lid that is provided with two lids and in which a stored item can be taken in and out from either side.

  Along with the development of the chemical industry, various plastic materials and products using them have been developed and used in every field from daily necessities to automobile and aircraft parts. At home, plastic products are used from trash to food containers.

  Among them, a container called Tupperware (registered trademark) has become widespread and is frequently used as a container for food. The general structure is a container body made of a polymer material, and a lid made of the same polymer material, covering the opening of the container, and having a rib on the periphery and a groove provided on the inner peripheral side of the rib. The container body is sealed by fitting the end of the opening of the container into the groove of the lid.

  One common use of such containers is to store cooked foods and store them in a refrigerator. In addition, there is a use method of preserving soy sauce, hot pepper, etc., which are encapsulated in a transparent film bag.

  A problem in the latter method of use is that the article at the bottom of the container is left unused for a long time. This is because the priority for taking out the articles is often in the vicinity of the lid, that is, the upper side of the container. In particular, in the case of food, there is a certain expiry date, after which it must be discarded, and so-called “first-in first-out”, which is consumed from the oldest, is important for preservation.

  From this point of view, when an existing container is overviewed, for example, as disclosed in Patent Document 1, a number of improvements in usability by adding a new structure to the lid portion have been disclosed. At present, there is nothing to deal with.

  Therefore, an object of the present invention is to provide a structure that is a container that can store small items and that can be used in order from the oldest.

  The present invention has been made as a result of investigations focusing on the fact that the above-mentioned problems can be solved by using separate inlets and outlets for storing and taking out articles.

  That is, this invention is a container with a double-sided lid characterized by having a cylindrical storage part main body and two lids of the structure which can be fitted to the opening part which the said storage part opposes.

  According to the present invention, the lid has a rib formed on a peripheral edge and an annular groove formed on the inner peripheral side of the rib, and the groove can be fitted into the opening of the storage unit body. It is the said container with a double-sided lid characterized by the above-mentioned.

  In the container of the present invention, the storage unit main body is cylindrical as described above, and either one of the opposed openings can be used for storing the product and the other can be used for taking out the product. Can be substantially eliminated that the old article is not removed indefinitely.

  Next, the form for implementing this invention is demonstrated. 1A and 1B are diagrams showing an example of a container with a double-sided lid according to an embodiment of the present invention. FIG. 1A is a perspective view and FIG. 1B is a cross-sectional view. In FIG. 1, 1 is a storage unit body, 2a is a first lid, 2b is a second lid, and 3 is a fitting groove.

  The storage unit body 1, firstly the lid 2a, and the second lid 2b can be made of plastic. Specifically, since the contents can be visually confirmed, it is desirable to use transparent polyolefin or the like. More specifically, polypropylene is used for the storage unit main body 1, and low-density polyethylene and ethylene-vinyl acetate copolymer that are more flexible than polypropylene are used for the first lid 2 a and the second lid 2 b. be able to.

  With such a configuration, the peripheral portion of the first lid 2a and the second lid 2b is elastically deformed by pressing the portion of the fitting groove 3 against the end portion of the opening of the storage unit body 1, and the storage is performed. Fits into the body. In actual use, articles are stored using the opening on either one of the first lid 2a and the second lid 2b as a storage port, and the opening on the other side is used as a take-out port. be able to.

  As described above, according to the present invention, it is possible to provide a container with a double-sided lid capable of “first-in first-out” of contents. In addition, this invention is not limited to the said embodiment, For those who have the normal knowledge in the field | area of this invention, for example, the cross-sectional shape of the container main body 1 is made into an ellipse or a rectangle. Needless to say, the present invention includes design changes within a range that does not depart from the gist including various modifications and corrections.
