Abstract

PROBLEM TO BE SOLVED: To preserve a food, a medicine and a chemical substance while keeping the specified quality thereof after a container is unsealed by providing an external container and at least a compact balloon-like container which is stored inside the external container and manufactured of a flexible material. SOLUTION: A plurality of compact balloon-like containers 2 which is formed of a flexible material such as rubber or polystyrene latex, and stores a food such as jam, a beverage such as Japanese sake, a medicine such as tablets, and chemical substances are stored inside an external container 1 forming a container of bottles and cans. The size of each container 2 is selected in a range of 1 cm to 10 cm according to the size of the external container 1 and the size of the food, etc., to be stored in the container 2. The container 2 is preferably heated for sterilization for keeping the quality of the food, etc., stored in the container 2. No bacteria is proliferated in the preservation using this double structure even when the container is preserved at 37 deg.C and a lid is unsealed every day, and the stable quality can be maintained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-structured container for preserving the quality of foods, medicines and chemicals, especially after opening, while maintaining the quality.

[0002]

2. Description of the Related Art Bottles and cans are used as containers for foods such as jams, drinks such as sake, and medicines such as tablets. For long-term storage, there is almost no problem unless opened, but after opening, it is almost impossible to seal as before opening, so the taste will deteriorate over time, the food will rot, and the effect will decrease. In order to avoid this, use of mini-containers has been attempted, but it is not always practical in terms of tidying, transportation, ease of use, and waste as well as cost.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a food, beverage or drink such as sake or a tablet or the like containing a drug and a chemical substance even after opening the product, the taste of the product may be lost, the product may become spoiled, It is an object of the present invention to provide a container capable of maintaining a constant quality without falling.

[0004]

In order to achieve the above object, a container according to the present invention comprises an outer container, and a small-sized container made of an elastic material housed in the outer container. And a balloon-shaped container.

[0005] Since the material of the small balloon-shaped container is a stretchable material, it can be easily sealed even after opening, and furthermore, the double-layer structure increases the degree of sealing. The quality of the goods and the like contained in the container can be kept constant.

[0006] If a small balloon-shaped container is further sterilized, the effect that bacteria in products and the like contained in the container hardly grow can be increased.

The size of a small balloon-shaped container is 1 cm or more.
When the size is about 10 cm, the degree of sealing is increased, and the inflow and outflow of outside air is further reduced. Therefore, it is more effective to keep the quality and the like of the product in the container constant.

Further, it is preferable that the elastic material of the small balloon-shaped container is rubber or polystyrene latex.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing a container having a double structure according to the present invention, in which a small balloon-shaped container 2 made of an elastic material such as rubber or polystyrene latex is housed in a plurality of outer containers 1. Is shown.

The small balloon-shaped container 2 depends on the size of the outer container 1 and the size of the food and the like to be put in the container 2.
The size is selected within a range of about 1 cm to 10 cm, and the number of the containers can be selected from four, five, and the like.

The objects to be put in the small balloon-shaped container 2 are:
Foods such as jams, drinks such as sake, pharmaceuticals such as tablets, and chemical substances.

The small balloon-shaped container 2 is made of an elastic material so that if it is broken into a container by a fork or a toothpick, the container 2 can be shrunk to a small size so as not to be too hindered even if it is directly inserted into the outer container 1. That is, rubber or polystyrene latex is preferred.

Further, the small balloon-shaped container 2 is preferably heated and sterilized in order to maintain the quality of the food and the like contained in the container.

The outer container 1 is made of a material currently used for containers such as bottles and cans.

Experiments were conducted on the effects of the present invention, and the results of the experiments are described below.

[Methods and Materials] A study was conducted on jam using a small balloon-shaped container made of rubber and a bottle of jam used for the eyebrows. The research was performed three times in total, but the experimental method is common. Open the bottles of commercially available strawberry jam [first time (Fig. 2), second time (Fig. 3)] and homemade plum jam [third time (Fig. 4)], divide the jam into several pieces, One part was stored in a jam bottle as it was at 4 ° C., and another part was stored at 37 ° C. (sealed or unsealed). Another part was injected into a sterile and non-sterile small balloon-shaped container with a special syringe, tied the injection port, and put it in a jam bottle. Jam bottles were sealed or unsealed and stored at 37 ° C. After the lapse of the number of days shown in the figure, the appearance and taste were judged blindly by four persons. In addition, several bacteriological tests were performed on the samples on the last test day. Jam jars were tightly sealed with Saran wrap, unsealed ones were capped with aluminum foil and replaced daily with fresh air. In the case of sterile preservation, the operation was a sterilization operation, and other things were prevented from being contaminated with bacteria as much as possible. The size of the bottle is 10cm in height
And the diameter of a bottle containing 250 g of jam and a small balloon-shaped container were about 3 cm.

[Results] The results are shown in FIGS. 2, 3 and 4. The bottle storage at 4 ° C. was used as a control because the appearance did not change much and the taste did not deteriorate in a maximum of 16 days. 3
When stored in a bottle at 7 ° C., the appearance did not change much, but the taste was slightly reduced in many cases. Bacterial tests showed that, especially for homemade plum jam, including the pathogens, they grew considerably. In the case of a small balloon-shaped container that was stored in a double structure, it was unsealed [the second time (Fig. 3) 4 and the third time (Fig. 4) 4]. It was impossible. In the case of sealing [2nd time (Fig. 3) 3rd time (Fig. 4) 3], 37 ° C
, The taste was almost unchanged compared to the control. In addition, even if a small balloon-shaped container is used, in the case of non-sterilization, there is a possibility of bacterial growth [first time (FIG. 2) 5].

[0018]

As described above, the rubber used for the eyebrow tofu is made into a small balloon-shaped container, and the outer container is bottled. The container is stored at 37 ° C., and the lid is opened every day. No bacterial growth occurred, the appearance did not change, and the taste was hardly reduced.
