Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applicable to commercializing foods and cosmetics having fluidity and semi-liquidity, such as creamy foods, cosmetics, mayonnaise, kneaded wasabi, kneaded mustard and miso. The present invention relates to the containers used in and the removal of foods, cosmetics and the like from the containers.

[0002]

2. Description of the Related Art Conventionally, foods and cosmetics having fluidity and semi-fluidity have been made into a synthetic resin disposable container consisting of a tube portion having a spout and a plug (lid) portion removable from the spout. It was filled and sold.

In such a disposable container, the tube portion is made of a flexible member so that the contents can be used up to the end, but a stopper (lid) is attached to the spout. Because it must be removable,
It is necessary to mold the spout portion so as to have a certain hardness, and thus it is still difficult to prevent the residual material from being left unused.

Further, in order to mold the spout portion so as to have a certain hardness, it is necessary to use a large amount of material. Therefore, it is inevitable to use a large amount of raw material resources. For food products, cosmetics, etc. sold in disposable containers, this had the effect of affecting the price structure.

On the other hand, in order to suppress the consumption of material resources required for molding a spout having a certain hardness, a mere rectangular synthetic resin bag without a spout, a soft film, etc., for food, cosmetics, etc. It is also practiced to fill and sell the product, but in this case, it is necessary for the purchaser to refill foods, cosmetics, etc. from a synthetic resin bag, a soft film, etc. into a replacement container.

[0006]

SUMMARY OF THE INVENTION From the viewpoint of resource saving and low cost, the present invention is a synthetic resin which is filled with a fluid or semi-fluid food or cosmetic and is not provided with a spout portion. An object of the present invention is to provide a stopper that can be used for bag-shaped containers such as bag-making and soft films, and that can be used repeatedly.

That is, the bag is attached to the bag-shaped container itself such as a synthetic resin bag or a soft film which is sold by filling with food or cosmetics having fluidity or semi-fluidity and which is not provided with a spout, An object of the present invention is to provide a stopper which can be used as it is and which can be used repeatedly.

[0008]

In order to solve the above-mentioned problems, the present invention proposes an externally removable stopper for a bag-shaped container.

That is, the plug of the present invention is a plug composed of a cylindrical member and a columnar member, and is a cylinder whose one end is open and the other end is closed by a top plate having a small hole for spouting. A columnar member that can be loosely fitted in the tubular member,
A plug having a length greater than the depth of the tubular member and a columnar member having a notch in the longitudinal direction.

[0010]

[Operation] A bag-shaped container is sandwiched between the tubular member and the columnar member,
Push the bag-like container into the tubular member with the columnar member, align the small hole for the spout of the top plate of the cylindrical member with the longitudinal notch of the columnar member, and face the position of the small hole for the spout. Open the part of the bag-shaped container that is open from the outside of the small hole. After that,
By applying pressure to the bag-shaped container, the food or the like in the bag-shaped container is pushed out by expanding the bag portion of the longitudinal cutout portion of the columnar member to the spout portion.

That is, the stopper of the present invention is a mere rectangular synthetic resin bag without a hard spout used for filling and selling foods and cosmetics having fluidity and semi-fluidity. It can be used by directly attaching it to a bag-shaped container such as a soft film.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a state in which a stopper of the present invention is attached to a soft plastic bag 1 filled with a fluid food.

The plug of the present invention comprises a columnar member 3 and a cylindrical member 2.
It consists of and. As shown in FIG. 3, one end of the tubular member 2 is closed by a top plate 4, and the top plate 4 is provided with a small hole 5 for spouting. Further, as shown in FIG. 2, the columnar member 3 can be loosely fitted into the tubular member 2, has a length larger than the depth of the tubular member 2, and has a notch 6 in the longitudinal direction. are doing.

When using the stopper of the present invention, the columnar member 3 is used.
The tubular member 2 is brought into contact with both sides of the bag 1, and the columnar member 3 is pushed to push the bag 1 into the tubular member 2. In this case, bag 1
Is made of soft plastic, the columnar member 3
The bag surface 1a on the side and the bag surface 1b on the side of the tubular member 2 are pushed into the tubular member 2 without breaking (FIG. 1). After pushing the columnar member 3 into contact with the top plate 4 of the tubular member 2,
The notch 6 and the small hole 5 of the top plate 4 are aligned with each other, and then the portion of the bag surface 1b facing the position of the small hole 5 is opened from the outside of the small hole 5 by a puncture or the like.

Thus, the bag 1 is surrounded by the columnar member 3 and the tubular member 2 and has a passage through the notch 6 communicating with the small hole 5 for the spout.

Then, by pressurizing the bag 1, the contents push out the bag portion located at the notch 6 and are pushed out from the small hole 5 for spouting.

When all the contents of the bag 1 have been pushed out, the columnar member 3 and the tubular member 2 can be removed and used in another soft plastic bag as a stopper.

In FIG. 4, a lid 7 is provided on the top plate 4. A lid 7 is provided which is rotatable around a fulcrum 8 on the top plate 4. By rotating the lid 7, the small hole 5 for the spout of the top plate 4 can be opened and closed. By providing the lid 7, the small hole 5 for spouting can be closed when not in use, so that the sealing can be maintained and the deterioration of the contents can be prevented.

The structure of the lid 7 is not limited to this, but may be removable from the tubular member 2. The point is that the small hole 5 for spouting can be closed when not in use.

Further, as shown in FIG. 5, the columnar member 3 and the tubular member 2 may be provided with a collar 9 and a collar 10, respectively, for stoppers. The collar 10 of the tubular member 2 may be a lid that also serves as a stopper.

Although not shown, the columnar member 3 and the tubular member 2 may be screwed together. If such a structure is adopted, the positional relationship between the columnar member 3 and the tubular member 2 can be fixed at a predetermined position. Therefore, when the bag 1 is pressurized, the columnar member 3 retracts and the cylindrical member 2 is removed. There is no fear of getting out.

1, 2 and 3, the case where both the columnar member 3 and the cylindrical member 2 have a cylindrical shape has been described, but the shape of the columnar member 3 and the cylindrical member 2 is only this. do not stop.
It is also possible to adopt a prismatic shape. The point is that when the soft plastic bag 1 is sandwiched between the columnar member 3 and the tubular member 2 and the columnar member 3 is pushed into the tubular member 2, a notch provided in the longitudinal direction of the columnar member 3 This is because the passage of the bag 1 leading to the small hole 5 for spouting should be formed in the part.

FIG. 6 shows a case where the prismatic columnar member 13 and the cylindrical member 12 are used as a stopper of the soft plastic bag 11. FIG. 7 is a view of the columnar member 13 as viewed from the side of the cylindrical member, and 16 indicates the position of the notch. In the figure, it is possible to provide a collar as represented by reference numeral 19. FIG. 8 is the top plate 14 side of the tubular member 12, and is provided with a lid 17 that can be rotated around 18 as a fulcrum. In the figure, reference numeral 15 is a small hole for the spout provided in the top plate 14. A collar can also be provided here, as indicated by reference numeral 19a.

Whether the tubular member has any of the above shapes,
It is more practical to make the opening side that contacts the soft plastic bag thicker than the top plate side. This is because it becomes easier when the bag is pressurized and the contents are pushed out.

9 and 10 show another example of use of the stopper of the present invention. That is, the cylindrical member 2 is placed at a symmetrical position.
The soft plastic bag 21 is sandwiched by the plate-like objects 22 having the holes 23, 23 into which the holes can be inserted. Next, the columnar member 3 having the cutout portion 6 and the tubular member 2 having the small hole 5 for spouting in the top plate are respectively inserted into the plate-shaped member 22 through the holes 23, 23.
Abutting the bag 21 from both sides of the columnar member 3 in the usual manner.
And push the bag 21 into the tubular member 2. The method of use is basically as described above, but in the case of this embodiment, by pressing the plate-shaped member 22 to narrow the interval,
The contents can be extruded more easily, and the remaining amount can be reduced.

[0026]

Industrial Applicability The stopper of the present invention is a mere rectangular synthetic resin bag without a hard spout, which is sold by being filled with foods and cosmetics having fluidity and semi-fluidity, a soft film, etc. The bag-shaped container can be used as it is by being attached to the bag-shaped container itself. Since the bag-shaped container does not have a rigid portion for the spout, it is possible to squeeze out the entire contents without leaving them.

After squeezing to the end, it can be removed and directly attached to another bag-shaped container for repeated use as a stopper.

When the stopper of the present invention is used, a mere rectangular bag made of synthetic resin, a bag-shaped container such as a soft film itself can be used. Therefore, unlike the conventional disposable container, it is not necessary to mold a rigid spout portion with a removable lid using extra raw material resources. Therefore, the raw material can be saved to about one-third of that of the conventional material, and thereby the price of foods, cosmetics, etc. to be filled in the bag-shaped container and sold can be suppressed.
