Description

  The present invention relates to a food packaging container made of plastics, and more particularly, to a food packaging container containing a transparent plastics pack capable of confirming contents suitable for storing fruits such as strawberries.

  Usually, high-quality fruits such as strawberries whose market value depends on freshness are packed in a transparent pack, and this transparent pack is placed in an outer frame made of foamed plastic resin or paper. It is sold with various patterns and pictures on the outside of the edge frame.

  However, the one with this border frame only placed around the transparent pack has a large external volume when carrying it, which is inconvenient when bringing it to the home or a gift destination, and eventually loses a sense of quality. It will be carried while stored in a transparent pack.

  For this reason, attempts have been made to develop a simple food packaging container that integrates the transparent pack and the outer frame, maintains the beauty, and does not hurt the contents.

  As a means for integrating the transparent pack and the outer frame, for example, as described in the following patent document, a bottom plate as an inner container is projected outward from the upper edge, and this projecting portion is used as a frame material. It is also conceivable to apply a system that engages or fits with the upper edge.

However, when these means are applied to a pack container containing strawberries or the like, it is necessary to fix the edge frame and lift the pack container and push it into the edge frame. There is a risk of damaging the stored contents, and considerable effort is required to prevent damage.

  The problem to be solved by the present invention is to provide a simple food container capable of easily fixing a transparent pack container containing high-quality small fruits such as strawberries, which are easily damaged, to an edge frame.

  The present invention is a state in which a transparent pack container containing high-quality small fruits is placed on a table such as a display shelf, and an edge frame made of foam plastics, wood, paper, etc. is fitted from above the transparent pack container, It is a simple container for food packaging that can be mounted and fixed.

  A normal transparent pack container is formed by integrally molding thin transparent plastics of the order of several tens of μm into a specific shape, and has a fin-like protrusion of about 5 mm on the outer periphery of the upper edge of the container. This ridge has elasticity, and when the edge frame made of foam plastics is fitted to this, the edge frame is made transparent by utilizing the elasticity of the rim and the inner surface of the edge frame made of foam plastics. By simply fitting from above the pack container, the transparent pack container containing the food contents can be locked and fixed to the edge frame.

  The means for locking and fixing the edge frame to the transparent pack container can be engaged and fixed as it is by adjusting the inner diameter of the edge frame in relation to the size of the transparent pack container. By providing a groove into the inner edge of the edge frame to insert the edge outer peripheral protrusion, just push the edge frame lightly from above the pack container without strictly adjusting the inner diameter of the edge frame and the size of the pack container. Thus, the edge frame can be fixed to the outer peripheral surface of the pack container.

  Further, the transparent pack container can be specially prepared for the simple food packaging container of the present invention instead of the ready-made product.

  For example, when the protrusion provided on the outer periphery of the upper edge of the pack container is formed long outward and the elasticity thereof is increased, the protrusion provided on the inner upper part of the edge frame when the edge frame is fitted from above the pack container. It can be easily inserted into the groove.

  Furthermore, the elasticity of the protrusion provided on the outer periphery of the upper edge of the pack container can be further utilized by forming a notch in the corner of the pack container.

  It is possible to provide a simple packaging food container made of a transparent pack container provided with an edge frame without requiring labor at a supermarket or a store.

  Since it can be fixed to the edge frame without touching the transparent pack container storing strawberries or the like, the stored items in the transparent pack fixed in the edge frame are not damaged.

  Various kinds of pictures and patterns can be applied to the border frame to add value and to give a sense of quality.

  When exhibiting at a storefront or when transporting to a store, if the outer frame is made higher than the contents, the stored contents can be prevented from being damaged even when stacked, and the display efficiency and transport efficiency can be increased.

  Hereinafter, embodiments of the present invention will be described based on examples applied to high-quality strawberry pack containers.

  FIG. 1 is a view showing an assembling procedure of a simple assembly container of the present invention.

  In the same figure, the pack container 1 which accommodated the strawberry is an integral molded product made of polystyrene, which is usually used for over-the-counter sales, and shows a state where it is placed on the display stand. The transparent container 1 is an integrally molded product made of polystyrene having an average thickness of 0.2 to 0.3 mm, the height is 40 mm, the length between the outer edges on the upper long side is 170 mm, and the outer edge on the upper short side The length between them was 115 mm.

  This transparent pack container 1 is formed with a protruding peripheral edge 11 having a width of 5 mm on the outer side of the upper peripheral edge. .

  The edge frame shown as 2 is a development of the folded edge frame 20 shown in FIG. This folding edge frame 20 is disclosed in Japanese Patent Application Laid-Open No. 2003-119651. In the case of the present embodiment, a band of polystyrene foamed resin having a thickness of 5 mm and a width of 40 mm is attached to the pack container 1. The wedge-shaped folds 21 are formed at four locations corresponding to the respective corners in accordance with the external size viewed from the plane, and both ends of the belt-like material are joined to be folded into a ring shape. The angle of the bending groove is 65 to 70 degrees. This folding edge frame 20 does not become bulky at the time of conveyance, and can improve transport efficiency. Then, a large number of strawberries are transported to the production or sales site, deployed on the edge frame 2 at the site, and used.

  Returning to FIG. 1, in the present embodiment, the edge frame 2 is formed with a groove 22 for inserting and locking the protruding peripheral edge 11 of the pack container 1.

  The groove 22 is formed over the entire circumference of the inner peripheral surface of the edge frame 2 corresponding to the position of the protruding peripheral edge 11 when the strawberry storage container 1 is inserted into the edge frame 2.
