Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a sealed packaging container for packaging foods, particularly soft and easily crumbling foods, including confectionery such as castella cake and shoot cake.

[Prior art]

When packaging soft and easily crumbly foods such as confectionery such as castella castella and shoot cake, etc., in packaging containers, the following formats were used.

(1) A type in which the opening of a container body made of plastic or the like filled with contents faces upward, and the upper surface is a film-like sealing member sealed from above.(2) Contrary to (1) above, A method in which the bottom surface of the container body is the upper surface and a film-like sealing member that seals the opening of the container body is the lower back surface (3) A method in which a paper tray or the like is fitted and covered without sealing the opening of the container body ( 4) A format in which the entire package is covered with an exterior such as pillow packaging in addition to the format described in (3) [Problems to be solved by the invention] The conventional packaging format described above had various drawbacks. That is, in type (1), when the seal member is peeled off and the contents are taken out, the seal member is too soft and may lose its shape or stick to hands. In addition, if the sealing member is on the upper surface, the package appearance will lack a high-quality appearance as a product.

In format (2), the package cannot be opened in the same position and must be opened after turning the package upside down, which has the same drawback as format (1).

Type (3) has low protection for the contents because it is not sealed, and is completely unsuitable especially for gel-like contents.

Type (4) is time-consuming to open and its sealing performance is inferior to types (1) and (2), but the gel content is similar to type (3).

Therefore, this invention provides a sealed packaging container that solves these drawbacks by simple means.

[Means for Solving the Problems] The sealed packaging container of this invention has a bottom surface of the container body filled with the contents as the upper surface, and a film that is tightly attached to the periphery of the opening of the container body to serve as a lid. The film-shaped sealing member is longer than the opening in one direction, preferably about twice the length of the opening, and the non-sealing part extending from the sealing part serving as the lid is the lower back surface. It is folded back at one side edge of the opening of the container body and overlapped with the sealing part.

Furthermore, the sealed packaging container may be temporarily fixed in one piece with a paper tray or the like placed under the film-like sealing member.

[Effect]

To open a sealed packaging container configured as above, if there is no tray, place it on a saucer with the upper surface facing up, or if there is a tray, temporarily secure it. Remove.

When the free end of the non-sealed portion of the folded film-like sealing member is pulled laterally, the sealed portion is successively peeled off from the folded portion. After the film-like sealing member is completely pulled out, the container body is removed upward, and the contents are placed on the saucer or paper tray without collapsing.

〔Example〕

An embodiment of this invention will be described according to the drawings.

The container body 1 shown in FIG. 1 is made of thermoplastic resin and has a thin rectangular parallelepiped box shape, preferably with a slight taper that widens from the bottom surface 2 toward the opening 3. The container body 1 shown in FIG.

A flange portion 4 is formed outwardly on the entire periphery of the opening 3. Then, on the edges of the flange parts 4', 4' on both opposing sides, tray temporary fixing protrusions 5 are provided at arbitrary locations (4 locations in FIG. A stopper protrusion 6 for a film-like seal member is provided at the edge of the portion 4''.
is provided at any location.

In the embodiment shown in FIG. 1, there are two stopper projections 6 near both ends. Alternatively, the stopper projection 6 may be modified to have a hook-shaped stopper projection 6' facing inward at both ends of the flange portion, as shown in FIG.

Further, a portion of the flange portion where the stopper projections 6, 6' are located is cut out to form a notch 7 for picking up the film-like seal member. When providing the notch 7, the center is appropriate.

It is also possible to omit the notch 7 in FIG. 1 and provide the stopper projection 6 at one location in the center.

In this way, a film-like sealing member 8 is prepared which is slightly larger than twice the size occupied by the entire outer peripheral edge of the flange portion 4 of the container body 1. That is, the width of the sealing member 8 is the width of the flanges 4' on both sides where the temporary fixing protrusion 5 is located,
4', and its length is slightly longer than twice the distance between the edges of the flange 4'' on which the stopper projections 6, 6' are located and the flange portion 4 opposite thereto.

Furthermore, a tray 9 as shown in FIG. 1 is prepared.

The tray 9 is made of cardboard, for example.

The central portion 9' of the tray 9 has approximately the same shape as the entire outer periphery (excluding the protrusions 5, 6, 6') of the flange portion 4 of the container body 1, and has wing portions 9'' on both sides with the folding line 10 as the border.
9'' follows. The wings 9'', 9'' are shorter than the depth of the container body 1 and have handling holes 11, 1 in the center as shown.
1 is drilled.

A temporary fastening protrusion insertion cut 12 is made on such folding line 10 at a position corresponding to the temporary fastening protrusion 5 provided on the flange portions 4', 4' of the container body 1.

In the sealed packaging container of this invention, for example, castella,
When sealing and packaging soft and easily crumbling foods such as sweets such as shortcake, first fill the container body 1 with the contents 13, and align one edge of the film-like sealing material 8 with the edge of the flange portion 4''. The opening 3 of the container body 1 is covered by a seal portion 8' occupying about half of the seal portion 8', and the opposing portions of the flange portion 4 are bonded to the flange portion 4 to seal the container body 1.

Then, the non-sealed portion 8'' of the film-like sealing member 8 is folded back at the edge of the flange portion 4.

Then, near the edge of the non-sealed portion 8'',
A stopper projection insertion cut 14 is cut at a position corresponding to the stopper projection 6 provided on the flange portion 4'', so the stopper projection 6 is inserted into the cut 14 and the free end of the non-sealed portion is inserted into the container body 1. Fix it.

If the stopper protrusion on the flange portion 4'' of the container body 1 is a hook-shaped stopper protrusion 6' as shown in FIG. Both side edges near the end of 8 may be inserted between the hook-shaped stopper protrusions 6'.

Next, the container body 1 is placed on the central part 9' of the tray 9 with the sealing member 8 facing down and the bottom surface 2 facing up, and the protrusion 5 of the flange part 4' is inserted into the protrusion insertion cut 12 of the tray 9. The packaging is completed by folding the wing portions 9'', 9'' of the tray 9 upward at the folding line 10.
The tray 9 is easy to handle due to the handling holes 11. Modifications of the tray 9 include both wing parts 9'',
9'' is further extended and bent to the bottom surface 2 of the container body 1, and both wing parts 9'' and 9'' are engaged with each other to form the container body 1.
It can also take the form of surrounding.

In some cases, the tray 9 may not be added; in that case, the flanges 4',
The tray temporary fixing protrusion 5 at 4' is no longer necessary.

After opening the sealed packaging container of this invention, the contents are 12.
To remove the container, if there is no tray, place the container body 1 on a saucer with the bottom surface 2 facing up, or if there is a tray 9, use the wings 9'', 9'' of the container body 1. , remove the cut 12 from the protrusion 5 (Fig. 3A), then pinch the free end of the non-sealed part 8'' of the folded sealing member 8 and pull it horizontally. 8' is peeled off (FIG. 3B). In this case, the notch 7 provided in the flange portion 4'' facilitates the pinching and pulling operation even if the excess length of the free end of the unsealed portion is narrow. After the sealing member 8 is completely pulled out, the container body 1 is removed upward, and the contents 13 are placed on the saucer or tray 9 without any collapse (FIG. 3C). At this time, the taper provided on the container body 1 makes the removal operation of the container body 1 even easier.

[Effect of idea]

Since the sealed packaging container of this invention has the bottom surface 2 of the container body 1 as the upper surface, the packaging appearance gives a high-class appearance as a product, and when the container body 1 is made of transparent plastic, the appearance is even more product-like. gets better.

In addition, since it is sealed by the film-like sealing member 8, the sealing property against the contents 12 is improved.
Highly protective, prevents leakage and staining, and
Since it is not necessary to perform a tipping operation or a gripping operation to take out the contents 12, it is possible to prevent the contents 12 from collapsing and getting your hands dirty. Furthermore, the unsealing operation is extremely simple, and this is achieved by the simple structure.
