Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to sealed containers, and more specifically, to food products,
This product relates to sealed containers and containers that are suitable for packaging heavy items such as pharmaceuticals or jewelry and watches.

[Conventional technology]

Containers used to package packaged items not only protect the packaged items, but also maintain the quality of the product up to the final point in the distribution process.
Therefore, the simplest sealing method is to attach a seal to the unsealed part of the packaging container, but this seal can be peeled off. Therefore, the reliability of the protection i!E function is poor.Therefore, in order to improve the guarantee function, a type of film backing of the entire packaging container has been adopted, but it is possible to reseal the container by replacing the entire film. 6s0, which is possible and can be expected to have a perfect guarantee function.

[Problems to be Solved by the Invention] In the conventional packaging containers as described above, there is an extremely high possibility of accidents such as removal and replacement of the contents (packed articles). Regarding medicines, etc., there is a possibility of foreign substances being mixed in (1)
Some kind of countermeasure is required. [Means for solving the problem] In order to solve the above-mentioned problems, the packaging container is composed of a packaging container body and a sealed bag accommodated in the packaging container body, and the packaging container body has A breaker that has a thin wall part that can be broken and an edge to break this thin wall part is provided, and the pressure applied to the sealed bag suppresses the destructive action of the edge on the thin wall part, and the pressure is released when the sealed bag breaks. This feature is characterized in that the edge of the breaker breaks the thin part when the breaker is pressed. [Embodiments] The structure of the present invention will be explained below with reference to embodiments shown in the attached drawings. First, in FIG. 1, the reference numeral 10 indicates a so-called box made of carton paper, that is, a packaging container body, and an opening 1 is formed on the end surface of the packaging container body 10 by a flap 11.
2 is in a state where it can be closed, and a window hole 14 is bored in the front or back surface plate 13, and this window hole 14 is closed by pasting aluminum foil 15, and the thin part is closed. has been formed. This aluminum foil 15
Since the purpose is to be torn, the material can be freely selected within the scope of the purpose, and may be a thin plastic film. A trademark, a manufacturer's name, etc. are printed on the front side of this aluminum foil 15. Furthermore, a breaker 16 for breaking the aluminum foil 15 is attached to the inside of the aluminum foil 15, and this breaker 16 has a deformed V-shaped slit 161 formed approximately in the center of one board. and a chevron-shaped edge 162 is formed,
With this slit 161 as a boundary, the V valley side is the fixed substrate 16
The V mountain side having the A1 edge 1θ2 is configured as a movable substrate 16B. ■Groove 16 on both sides of Surin 1-161
3 extending in the width direction of the board, and the edges 162 are for breaking the aluminum foil 15, so some mechanical strength is required, and for this purpose, a lining 164 is applied and reinforced. There is. The ends of the fixed substrate 16A and the movable substrate 16B are connected by a tension spring or rubber strip 17, which is an elastic body, and the fixed substrate 16A is fixed to the edge of the window hole 14. In other words, the movable substrate 16B1 has a habit of constantly bending toward the fixed substrate 16A with respect to the edge 162. In the packaging container main body 10 as described above, food, which is an object to be packed, is sealed with an airtight bag 20 formed of a thin film such as a polyester film, together with an inner container 21. is filled with air or an inert gas, and the airtight bag 20 is inflated and brought into close contact with the inner surface of the packaging container body 10. Furthermore, due to the air pressure inside the airtight bag 20, the breaker 16
The movable substrate 16B is expanded in the same plane as the fixed substrate 16A against the elasticity of the rubber strip 17. That is, the edge 162 is parallel to the thin aluminum foil 15. After the food is packed in the packaging container body 10, the opening 12 is closed by folding the flap 11, and a seal or the like is pasted. , rOther Examples] In the above embodiments, a window hole 14 was made in the packaging container body 1G, and an aluminum foil 15 was pasted thereon.However, the material of the packaging container body 10 was changed from carton paper to If the material is changed to plastic, only the portion corresponding to the window hole 14 can be made thin by reducing the wall thickness, and aluminum foil can also be used instead. Alternatively, if the elasticity of the material itself can be used as a breaker to change the direction in which the edge 162 breaks the aluminum foil 15, the elastic body can be omitted.

【Effect of the invention】

As is clear from the above explanation, food to be packaged is placed in a sealed bag and pressure is applied to it, and the sealed bag is brought into close contact with the packaging container body, pushing the edge of the breaker against the elastic body. Since it is configured to maintain its posture along the container body, if the airtight bag is tampered with, it will rupture and the pressure gas will escape, causing the breaker to be pressed against the inner surface of the container body due to internal pressure. The container stands upright, breaks the meat WI portion of the aluminum foil, etc., and can notify that some processing has been applied to the item to be packaged in the packaging container body.

Claims (1)

[Claims] (1) A packaging container main body and a sealed bag housed in the packaging container main body and capable of enclosing a packaged article, wherein the packaging container main body has at least one thin wall portion and the airtight bag located inside the thin wall portion to seal the bag. The breaker has an edge that can be kept in an inoperative state by the internal pressure of the bag, and an elastic body that causes the edge of the breaker to always stand up toward the thin wall part, and the internal pressure is reduced when the sealed bag breaks. A sealed container characterized in that the thin wall portion of the packaging container body is broken by a breaker.
