BACKGROUND OF THE INVENTION The present invention relates to a container for enclosing and sealing a relatively viscous paste-like seasoning, a paste-like detergent, or a paste-like cosmetic, and discharging the contents. With a palm or finger of the hand and pressurize, to peel off and tear off the seal on the side where the outlet for the contents is formed, and discharge the contents. The present invention relates to a disposable container suitable for applying to a specific part of a subject or extruding and supplying a predetermined amount to a specific target part.

[0002]

2. Description of the Related Art Conventionally, a disposable container containing, for example, a paste-like substance (paste, butter, jam, soft cheese, etc.) is usually provided with an opening notch in a seal portion, and the container is torn from this notch to open an opening. And the contents are extruded and discharged or flowed out to take out.

[0003] However, many of the above-mentioned open-type containers are difficult to open for infants or the like with one hand that is inconvenient or have weak fingertips. If the container is wet or water is attached to the container, there is a problem that the grip of the notch portion to be torn is slippery and cannot be opened, or the container is dropped.

In view of the above, the present applicant has disclosed a disposable container which can be easily opened with one hand, as disclosed in Japanese Utility Model Application No.
No. 119385 and several other proposals have already been made.

[0005] In the container proposed above, when the container is grasped with a hand or with a fingertip and a pressing force is applied to the container, a peeling and tearing seal portion formed in the container is torn open to discharge the contents. Since the outlet is formed, the problem of the conventional product has been solved.

By the way, in such a disposable container,
Paste foods such as jams and soft cheeses are stored therein, and the contents may be applied or supplied from the container as it is onto an object such as bread.

However, the previously proposed container is devised in that the outlet for the contents is formed by the pressing force, so that it is convenient to apply the contents to an object such as a bread as described above. No good form is considered.

[0008]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a disposable container in which a film-like sheet is sealed by heat sealing or the like, and is peeled and split by receiving a pressing force. It is an object of the present invention to develop a disposable container having a convenient form for applying an object to an object such as a bread.

[0009]

Means for Solving the Problems The object of the present invention, which has been made to solve the above-mentioned problems, is to provide a bag-like sheet formed by laminating a synthetic resin film, aluminum foil, or the like, or by sealing a non-laminated film sheet. A container, wherein the seal portion for forming a discharge port for contents by peeling and tearing of the seal portion is formed into a narrow bell-shaped or mountain-shaped seal toward the inner side of the container. Form and
In a disposable container formed by providing a small projection seal portion in the form of a teat at the top of the bell-shaped or mountain-shaped seal portion, an unsealed opening communicating with the outlet side of the contents of the outlet through a chamber. And a narrow projection or a tapered tongue-like portion extending from the discharge port to the opening.

Next, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a plan sectional view of a first embodiment of the container of the present invention, FIG. 2 is a plan sectional view of a second embodiment, FIG. 3 is a plan sectional view of a third embodiment, and FIG. FIG. 5 is a plan sectional view of the fifth embodiment, FIG. 6 is a plan sectional view of an example of the previously proposed container, and FIG. 7 is a plan sectional view of a conventional example.

[0011] In these figures, reference numeral 1 denotes a stack of two sheets each having at least opposing surfaces formed so as to be heat-sealable, or one sheet is folded in the length direction to be doubled, A bag-shaped container formed by heat-sealing two or three sides of these four or three sides. In a conventional container, a notch 6 is formed in a seal portion 3 where a cut opening is to be formed as shown in FIG. 6 as an example. Then, the bag was cut from the notch 6 to form an opening. The bag-shaped container to which the present invention can be applied is not limited to a heat-sealable container, and may be an adhesive type. Further, the present invention is also applicable to a bag of a type in which a material formed in a cylindrical shape from the beginning is heat-sealed or bonded at an appropriate pitch.

However, as described above, the opening forming structure as shown in FIG. 7 has various problems. In view of this point, the present applicant has proposed a container shown in FIG. This container does not have a notch, but forms a seal portion 8 formed on the inner side of the container to be peeled and cleaved by applying pressure to the container.

However, the proposed container shown in FIG. 6 can solve the problem that the outlet can be formed by easily peeling and tearing with one hand, but the paste-like container such as jam or glue can be solved. In order to apply foods and the like to objects such as bread, it was found that there was a point to be improved. The container of the present invention shown in FIGS. 1 to 5 has been completed for the purpose of improving this point.

In FIGS. 1 to 5, the same reference numerals as those in FIGS. 6 and 7 denote the same members or the same parts.
The feature of the container of the present invention is that a convenient opening for applying the content to an object such as a bread when the content is extruded is formed, and the seal portion 8 to be peeled and cleaved is a container 1.
A flow resistance portion for reducing the flow velocity of the contents is appropriately formed between the split opening and the opening 9 formed in the seal portion 5 by unsealing in advance. As for these points,
This will be described with reference to FIG. The flow resistance part is not indispensable to the container of the present invention, and it is preferable that the flow resistance part is not provided in the case of a highly viscous paste-like substance such as jam or soft cheese.

In FIG. 1, a seal portion 8 formed below the inside of the container 1 has seal lines 81, left and right on both sides thereof.
8r is formed substantially flat, and has a bell-shaped or chevron-shaped narrow width which is continuous with the seal lines 8l and 8r at a substantially central portion and whose top side faces the inside of the container. Are formed on the seal line 8a, and a nipple-like portion 8p is formed on the top.

In FIG. 1, a thin tongue-shaped portion extending below the sealing portion 8 and outside the container 1 is provided.
That is, an opening 9 is formed in the narrow protruding portion or tongue-shaped portion K by non-sealing, and a chamber 10 is formed between the opening 9 and the sealing portion 8. In this room 10,
Immediately below the seal line 8a to be peeled and cleaved, a resistance seal portion 11 having a shallow arc shape here is formed to function as a flow velocity resistance portion. 9a is a brush substitute portion formed by making the lower end side of the opening 9 zigzag.

By forming the container 1 in this manner,
The paste-like substance contained in the container 1 is
Brush-shaped opening 9 formed in the form of a tongue extending outside
And can be easily extruded at a reduced flow rate.

That is, the container 1 is squeezed by holding it tightly.
Is applied, the stress due to the pressure is concentrated on the nipple 8p of the seal line 8a where the seal portion 8 is peeled and cleaved, so that the seal is separated from the nipple 8p, and the contents are filled in the chamber. Start to leak to the 10 side. The peeling of the nipple 8p spreads like an opening along the peeling and tearing seal line 8a, depending on the pressure, and the outflow of the contents is expanded.

The contents (for example, a paste substance having a relatively low viscosity) flowing out from the outlet formed by the above-mentioned peeling and tearing are applied to the chamber 1 by strong gripping force applied to the container.
However, since the chamber 10 is provided with a resistance seal portion 11 functioning as a flow velocity resistance portion,
The contents flowing out from the peeling and tearing discharge port do not flow directly to the outside from the opening 9 formed in the seal portion 5 in the tongue shape outside the container 1. Therefore, the contents are temporarily stored in the chamber 10 by the action of the resistance seal portion 11 and gradually flow out of the opening 9 to the outside, so that the contents do not jump out directly to the outside. here,
The position of the opening 9 is formed in a narrow tongue-like shape outside the container at the lower side of the container 1 in communication with the chamber 10, so that this portion, that is, a narrow protrusion or a tongue-like shape is formed. Section K can be used for application of the contents, so to speak as a brush, a spatula or a knife.

The tongue-like opening 9 formed on the outside of the container 1 is used in the same manner as a knife or a spatula. Two sheets are stacked and heat-sealed around the opening. In a bag-type container of a type, it is desirable to use one sheet material that is thicker than the other sheet material, for example, about 70-100 μm.

As a material of the above-mentioned sheet material, for example, a film-like sheet conventionally used for a stick type or pillow type container is used. For example, the outer layer is made of a polyester film or the like having good printability, the intermediate layer is made of an aluminum foil or polyester film having good gas barrier properties or light-shielding properties, and the inner layer is made of polypropylene or EVA based on heat sealing properties. Using film 2
A film having a lamination structure of three layers is used. Of course, a single-layer film having all or any of the functions described above may be used.

The flow resistance part by the resistance seal part 11 of the above example may be formed as shown in FIG.

In the example shown in FIG. 2, an arm-shaped resistance seal portion 13 connected to the seal line 8l or 8r is provided in the chamber 10.
Is formed, and the flow path shape of the chamber 10 itself is devised so as to function as a flow velocity resistance portion. As a result, the non-sealed opening 9 of the portion which has been formed in the tongue-like shape outside the container 1 in advance is formed at the position shown in FIG. .

The flow resistance section in FIGS. 1 and 2 can be arbitrarily set or changed in its shape and the flow path shape of the chamber 10 according to the viscosity of the liquid or paste-like substance as the contents. .

The flow resistance portion does not use the seal portion 11 or the seal portion 13 and, for example, by loading a continuous foam having a large foam diameter into the chamber 10 so that the viscosity of the content is low. In the case of the thing, the flow velocity of the outflowing contents can be remarkably relaxed, and the outflow can be prevented. Further, a flow rate resistor made of a continuous foam or the like may be provided near the cleavage discharge port inside the container 1. Furthermore, as a flow velocity resistor,
The material is not limited to the continuous foam of the above example, and may be a member through which liquid can permeate and flow, for example, a nonwoven fabric, a coarsely woven or knitted fibrous material, or the like.

FIG. 3 shows an example of the container of the present invention in which the seal portions 2, 3, and 4 are formed so that the outer shape of the container 1 is substantially oval, and the flow velocity resistance portion is not formed in the chamber 10. FIG. 4 shows the shapes of the seal portions 2, 3, 4 forming the internal shape of the container 1,
FIG. 5 shows an example of the container according to the present invention in which the shape of the seal portion 8 to be peeled and cleaved is different from each of the above-mentioned examples. It is each showing an example of a container. Here, in the container shown in FIGS. 3 and 5, it is not necessary to separately form a tongue-shaped extending portion depending on the outer shape of the container itself.

In the above-described container according to the present invention, two or more containers may be provided in parallel in the length direction, or may be provided in a laminated structure on the thickness side. When the container has a multi-row structure or a multilayer structure as described above, the container of the present invention is suitable as a container for simultaneously discharging two or more kinds of paste-like substances, for example, ketchup and mustard, or a container for simultaneously applying to a target. is there.

[0028]

The present invention is as described above. In a container in which the sealing portion is partially peeled and ruptured by the pressure applied to the container and the contents are extruded, the outlet formed by rupture is substantially removed. A bell-shaped or mountain-shaped thin seal line is formed, and a nipple-shaped peeling projection is formed at the top of the seal line, so that an opening that is peeled and cleaved by applying pressure can be easily formed. In addition to the effect that it can be made to work, there are the following unique effects.

In the container according to the present invention, a non-seal opening communicating with a discharge port of the contents formed by peeling and tearing the seal portion is connected to the discharge port so that a tongue-shaped or thin piece is formed on the outside of the container. Since the opening is formed so as to form a width protruding portion and the opening is formed in a brush shape or a spatula shape, the content extruded from the discharge port of the content formed by the above-mentioned peeling and tearing is used as a pan or the like. Can be applied as it is to the application target, that is, there is an inherent effect that the opening of the container and its contents can be extruded, and the application of the extruded contents to the object can be performed with one hand in a series of operations. . In addition, since the application amount can be adjusted as it is with one hand, it is more convenient.

As a result, for example, by using a paste-like seasoning such as butter in the container of the present invention, jams and butters are divided into small portions at restaurants such as restaurants and cafes, and You can save time and effort. Moreover, since the coating can be performed by the container itself, there is an advantage that a butter knife, a spoon or the like is not required.
