JPH03256867A - General purpose inner packaging container - Google Patents

Abstract

PURPOSE: To leave air into the inside of a container and eliminate a danger to permeate air into the inside of an article to be packaged in a bag and prevent the quality of the article from deteriorating by making the wall body of the packaging container permeable. CONSTITUTION: An all-purpose packaging container is constituted of two half members 2, 3 for instance. Ribs 4 are formed in the main parts of the wall bodies of the half members to impart a large resistance against the deformation to the packaging container. Holes 7 are formed on the wall bodies in which the ribs of the packaging container are provided. After a gift assembly has been put in the all-purpose packaging container and closed, the packaging container is dropped in a bag which is stuffed with coffee and vacuumized and sealed. In this time, the inside of the bag is also vacuumized through the holes 7 and deaerated. And hence, the aroma and fragrance of the enclosed coffee are not impaired.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention primarily relates to an internal general-purpose packaging container that is filled with coffee and placed inside a vacuum-packed bag. This general-purpose packaging container particularly refers to containers for holding small prizes.

(Prior Art) Vacuum packaging of various products, such as coffee, is widely practiced in practice, and such single-vacuum packaging is described in many manuals and patent documents.

The reason why vacuum packaging, such as coffee packaging, is so important is that when such packaged items are placed under conditions where they are exposed to the air, their aromas and aromas are rapidly lost. , because it gives off a bad odor. Packaged items such as ground coffee deteriorate more quickly. For this reason, if a packaged item is placed in a bag and the packaged item must be kept under vacuum until it is used, it should be ensured that no oxygen remains inside the bag. It is also important to prevent oxygen from entering the bag.

BACKGROUND OF THE INVENTION In many countries, it is common practice in consumer goods sales to include prizes in the packaging of popular products. Although it is a good idea to attach such prizes to the product packaging at the risk of loss or theft, it is also possible to place such prizes inside the product package before it is finally closed. It is possible. One example of how such prizes can be distributed with consumer goods is a clean carton containing small plastic toys inside a clear bag.

However, the method of distributing such prizes, for example,
It is unsuitable for use in bags for vacuum packaging coffee. In fact, attaching prizes to packaging bags is an expensive task. This is because not only extra equipment and man-hours are required to attach the prize, but also extra space is required for shipping and display due to the larger outer dimensions of the package. In addition to this, there is the risk of loss and theft as already explained. Another method is to put the prize in a plastic bag and place the bag loose inside the packaging container, but this method also solves the problem, similar to the method of putting cleaning agent in the carton. It is inappropriate for this purpose. In fact, the bags used to vacuum-pack coffee are made small in size to make them easier to grasp, so the prizes that can be placed inside are limited to small items. If we were to adopt a method where a very small prize was placed inside a coffee packaging bag before the coffee was packed, then when the package was opened, the title would be to reveal the prize from inside the package. There is a big risk that it will become very difficult to open the package and find the prize inside the coffee.

If it is not possible to identify the prize, there is a risk that, for example, when brewing coffee, the prize will be poured in with the coffee. Furthermore, if, for example, a small prize placed in a plastic bag is automatically added in a packaging process line that packs coffee into coffee bags, the shape of the prize assembly is not constant, and the prize If the assembly easily falls or is fed into the coffee bag, there is a risk of slowing down the packaging process.

(Problems to be Solved by the Invention) The present invention relates to an internal general-purpose packaging container that can be used to confine small items such as prizes in a vacuum-packed bag for coffee, for example. There is no risk of air remaining inside the packaging container.
It is an object of the present invention to provide an internal type general-purpose packaging container that does not have the risk of allowing air to penetrate into the interior of the packaged product in the vacuum-packed bag, and therefore does not pose the risk of degrading the quality of the packaged product. .

(Means for Solving the Problems) In a preferred embodiment of the present invention, the spherical packaging container has two
It consists of two mold halves, which are easy to separate and close again. In order to ensure that no air remains in the package after each completed package has been evacuated, holes are provided in the walls of the packaging container. Before a gift to be packaged, such as a necklace pendant, is inserted into a packaging container, the pendant is wrapped in a film with minute holes and then closed. The automatic delivery device is installed in the coffee packaging process before the bag of coffee is placed in the vacuum chamber. Prior to sealing the package, a vacuum is applied to the vacuum chamber to remove air from the interior of the coffee bag and packaging container.

In this way, when the package is opened and the contents are consumed, the quality of the contents of the package is not degraded, and the prize packaging container can be taken out. This packaging container can be easily opened to take out the prize therein, and can then be closed again and used as a small toy.

A preferred form of packaging is made using polypropylene. However, the packaging can also be made of any material that is compatible with the food product. This material can maintain its shape even when vacuumed. Moreover, this packaging container can be made using a material that can coexist with food, can maintain its shape, and has minute holes.

Although the preferred form of the packaging container described above is spherical,
This shape can be changed according to preference or necessity. Further, the dimensions of the packaging container can be adapted to the dimensions of the prize to be packaged and the capacity of the exterior package of the packaged object into which the prize is placed.

Having described a preferred form of a general purpose packaging container for use with coffee vacuum packaging bags, this general purpose packaging container can also be used for vacuum packaging any other packaged item.

〔Example〕

Although this specification includes claims that particularly point out and strictly claim the contents of the present invention, reference will be made to the drawings, and the same reference numerals will be used for substantially the same components. Examples of the present invention will be described in detail.

The universal packaging container (see FIG. 1) is constituted by two halves 2.3. Ribs 4 are formed in the main part of the wall of this half-form member. This rib 4 is designed to provide the packaging container with a high resistance to deformation, to be able to create such a high resistance using a minimum amount of plastic material, and to provide gripping when opening and closing the packaging container. This is to make it easier. The tip 5.6 of the packaging is a smooth surface on which any instructions or instructions for the use of the packaging can be displayed. The hole 7 is provided in the wall of the packaging container, which is shaped like a rib.

FIG. 2 shows how the male threaded portion 8 of the half mold member 3 is screwed into the female thread portion 9 of the half mold member 2.

FIG. 3 is a top view of the mold half 2, and in this FIG. 3, using the smooth area 5 of the mold half, to the consumer:
A method for displaying the packaging container to let people know that it is made of a material 10 that can coexist with food will be shown.

FIG. 4 is a top view of the mold half 3, which shows how to use the smooth surface 5 of the mold half to inform the consumer how to open the packaging container 11. .

FIG. 5 shows how to form a prize assembly 14 by wrapping a prize in a plastic film 13 with minute holes. This prize, in the form shown in this figure, is a necklace pendant.

FIG. 6 shows how to position the prize assembly 14 within the mold half 3 so that it can be easily covered using the mold half 2.

As is known, the dimensions of the holes 7, or the dimensions of the holes if the packaging container is made of a material with minute holes, are determined by the volume of air extracted from the packaging container and the size of the holes. It is a function of the length of time to perform the sampling operation.

In a preferred form, the general purpose packaging container is made of polyethylene and is spherical as shown in the drawings. The diameter of this general-purpose packaging container is 3.5 centimeters. Each mold half is provided with four holes, each of which has a diameter of 4 millimeters.

After the prize assembly is placed in a general-purpose packaging container and closed, the general-purpose packaging container is dropped into a bag filled with 250 grams of ground coffee. The bag thus filled is sealed by applying a vacuum for 10 minutes. When a bag of coffee subjected to this procedure is opened three months later, it can be seen that the aroma and aroma of the coffee sealed inside is intact.

It is clear that the preferred embodiments described above do not limit the concept of the invention. The packaging container can be of any shape that fits inside the packaging container to be vacuum packaged. Additionally, the packaging container can be constructed from several parts, as long as the prize assembly can be evacuated and can withstand the evacuating operation without damage. Additionally, the method for opening or keeping the packaging container closed may be of any suitable type, such as threaded, bayonet, snap-fit, or friction-fit. I can do it.
