Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention is suitable for use with relatively high viscosity paste seasonings, paste detergents, or pastes. - When sealing and sealing cosmetics in strip form and discharging the contents, open the container. By applying pressure with the palm of your hand or fingers, open the side of the cylinder where the outlet for the contents will be formed. - Especially regarding disposable containers whose contents can be discharged by peeling and tearing the container. , suitable for applying the contents to a target or extruding a predetermined amount to a specific part of the target. This relates to disposable containers.

0002

[Conventional technology]

Traditionally, it has been used to store, for example, pasty substances (glue, butter, jam, soft cheese, etc.) Disposable containers that have been sealed usually have an opening notch in the seal and can be opened through this notch. Tear open the container to create an opening that allows the contents to be forced out or spilled out. It is common to take it out.

0003 However, the above-mentioned opening-type containers are not suitable for people who have difficulty using one hand or have weak fingertips. Many children find it difficult to open their mouths, and even healthy people may have wet fingers. If there is water on the container or if there is water on the container, hold the notch part above The problem is that the container may slip and be unable to be opened, or the container may fall out.

0004 In view of these points, the applicant has developed a disposable package that can be easily opened with one hand. Containers have already been proposed in Utility Application No. 1-119385 and several others.

[0005] The previously proposed container can be gripped by hand or fingertips, and pressure is applied to the container. When the container is added, the peel-off seal formed on the container ruptures, opening the outlet for the contents. Because of this, the problems associated with conventional products have been solved.

[0006] By the way, disposable containers like this are not suitable for storing products such as jam or soft cheese. - If food such as strips is stored and the food is placed directly from the container on top of the object such as bread, etc. May apply or supply containers.

[0007] However, the previously proposed container has the disadvantage that the outlet for the contents is formed by pressing force. Because it is a devised product, it is suitable for applying the contents to objects such as bread as mentioned above. No consideration is given to convenient forms.

[0008]

[Problem that the idea aims to solve]

Therefore, the problem to be solved by the present invention is to heat-seal a film-like sheet. In a disposable container that is sealed with A disposable product with a convenient form for applying the contents to objects such as bread. The challenge is to develop a container.

[0009]

[Means to solve the problem]

The structure of the present invention, which was created with the aim of solving the above problems, is based on a synthetic resin film. For sealing film-like sheets with or without lamination of aluminum foil, aluminum foil, etc. A bag-like container formed by peeling and tearing the seal portion to open the outlet for the contents. The seal part to be formed is shaped like a bell or chevron toward the inside of the container. The seal is formed into a narrow seal having a shape, and the top of the bell-shaped or mountain-shaped seal portion. In the disposable container formed by providing a small protrusion seal portion having a papillary shape on the The downstream side of the outlet is formed into a tongue-like part extending outside the container, and the tongue It is characterized in that an unsealed opening communicating with the discharge port is formed in the piece-like part. It is something that

0010 Next, embodiments of the present invention will be described with reference to the drawings. Figure 1 shows the flat surface of the first embodiment of the container of the present invention. 2 is a cross-sectional view of the second embodiment, and FIG. 3 is a cross-sectional view of the third embodiment. 4 is a plan sectional view of the fourth embodiment, FIG. 5 is a plan sectional view of the fifth embodiment, FIG. 6 is a plan sectional view of a conventional example, and FIG. 7 is a plan sectional view of an example of the previously proposed container.

[0011] In these figures, 1 is two sheets with at least opposing surfaces formed to be heat-sealable. by stacking two sheets of material, or by folding one sheet material in the length direction to make it double, A bag-shaped container is formed by heat-sealing these four or three sides 2 to 5 times. For example, as shown in FIG. A notch 6 is formed in the loop part 3, and the bag is cut from this notch 6 to form an opening. Was. Note that the bag-like containers to which the present invention can be applied are not limited to those that are heat-sealable. , it may be of adhesive type. In addition, the material was originally formed into a cylindrical shape. It can also be applied to bags that are heat-sealed or glued at appropriate pitches.

0012 However, with the opening structure shown in Figure 7, there are various problems that can arise. As stated above. In view of this point, the present applicant has proposed a container shown in FIG. This container does not have a notch and is shaped by applying pressure to the inside of the container. A seal portion 8 is formed which can be peeled off and torn.

[0013] However, the proposed container shown in Figure 6 can be easily peeled and torn open with one hand to open the outlet. Although we were able to solve the problem of being able to form There are some points that need to be improved in order to apply strip foods to objects such as bread. It turns out. In order to improve this point, the invented container shown in Figures 1 to 5 was completed. It is.

[0014] Therefore, in FIGS. 1 to 5, the same reference numerals as in FIGS. 6 and 7 indicate the same members or parts. However, the feature of the container of the present invention is that when extruding the contents, the contents are Formed with an opening convenient for application to objects such as A seal portion 8 is formed inside the container 1, and the tear opening and the seal portion 8 are formed inside the container 1. - Reduce the flow rate of the contents between the opening 9 previously formed in the seal part 5 by non-sealing. Regarding these points, since the flow velocity resistance part is appropriately formed to increase the flow velocity. , will be explained based on FIGS. 1 to 5. Note that the flow rate resistance section is essential to the container of the present invention. rather than viscous pasty substances such as jams and soft cheeses. In this case, it is preferable not to provide it.

[0015] In FIG. 1, the seal portion 8 formed in the lower part of the interior of the container 1 is located on both the left and right sides. The seal lines 8l and 8r are formed almost flat, and the seal lines 8l and 8r are formed approximately in the center. A bell-shaped or mountain-shaped shape that is continuous with lines 8l and 8r and whose top side faces the inside of the container. The seal line 8a is formed into a narrow seal line 8a that is peeled off and torn to form a seal line 8a. A head 8p is formed.

[0016] In FIG. 1, a tongue-shaped portion extending below the seal portion 8 to the outside of the container 1 is shown. An opening 9 is formed in the non-sealed portion, and this opening 9 and the sealed portion 8 is formed into a chamber 10. This chamber 10 contains a seal line to be peeled and torn. Immediately below 8a, there is a resistance in the form of a shallow arc to function as a flow resistance section. A seal portion 11 is formed. 9a is to make the lower edge of the opening 9 into a zigzag shape. This is a brush substitute part made of

[0017] By forming the container 1 in this way, the paste contained inside the container 1 can be The substance is passed through the brush-like opening 9 formed in the form of a tongue extending from the outside of the container 1. Can be extruded easily and at well-reduced flow rates.

[0018] In other words, if you apply pressure to container 1 by squeezing it tightly, the pressure will cause Stress is concentrated on the papilla 8p of the seal line 8a where the seal line 8a is peeled and split in the seal portion 8. Therefore, the seal of the seal part 8 peels off from this papilla 8p, and the contents leak out to the chamber 10 side. start. The peeling of the papilla 8p may occur along the peeling/tearing seal line 8a, depending on the pressure. It expands like an opening, and the outflow of the contents expands.

[0019] The contents (e.g. relatively viscous A paste-like substance with low strength) is forced into chamber 10 by strong grip force applied to the container. However, this chamber 10 has a resistance seal part 11 that functions as a flow rate resistance part. Therefore, the contents flowing out from the above-mentioned peeling and tearing outlet are The liquid flows directly to the outside through an opening 9 formed in a tongue-like manner on the outside of the container 1. Never. Therefore, the contents are temporarily accumulated in the chamber 10 due to the action of the resistance seal part 11. Since the contents flow out slowly from the opening 9 to the outside, the contents do not fly directly to the outside. It won't come out. Here, the position of the opening 9 is such that it communicates with the chamber 10 and is located below the container 1. Since the tongue-like part is formed on the outside of the container, it is difficult to touch this part with a brush, spatula, or so to speak. can be used like a knife to apply the contents.

[0020] An opening 9 extending in the form of a tongue on the outside of the container 1 can be opened with a knife or spatula. In order to use it in the same way as For type bag containers, one sheet material is thicker than the other sheet material, e.g. For example, it is desirable to use a material with a thickness of about 70 to 100μ.

[0021] In addition, as for the material of the above-mentioned sheet material, conventionally, for example, stick type and Use the film-like sheet used for pillow-type containers. For example, outside The surface layer is made of polyester film with good printability, and the middle layer is made of gas barrier or shielding material. Aluminum foil or polyester film with good optical properties are used for the inner layer with heat sealability in mind. Lamination with 2 to 3 layers using polypropylene or EVA films. Use a film with a thin structure. Of course, a single layer film can provide all of the above functions. It may be equipped with all or any of the above.

[0022] The flow velocity resistance section formed by the resistance seal section 11 in the above example should be formed as shown in FIG. There is also.

[0023] In the example of Fig. 2, an arm-shaped resistor is provided in the chamber 10 that is continuous with the seal line 8l or 8r. The seal part 13 is formed to improve the flow path shape of the chamber 10 itself, thereby reducing the flow velocity resistance. It is designed to act as a part. As a result, a tongue-like shape is formed on the outside of the container 1 in advance. The non-sealed opening 9 extending from the chamber 10 is located at the end of the flow path formed by the chamber 10. It is formed at the position shown in FIG.

[0024] The flow rate resistance section in FIGS. 1 and 2 above has its shape and the flow path shape of the chamber 10 It can be set or changed as desired depending on the viscosity of the liquid or paste-like substance. Ru.

[0025] Note that the flow rate resistance section does not use the seal section 11 or the seal section 13 described above, and for example, the foam diameter By loading a large open foam into chamber 10, the viscosity of the contents is low. In this case, the flow rate of the outflowing contents can be significantly reduced and splashing out can be prevented. Also , a flow velocity resistor made of continuous foam or the like is provided inside the container 1 near the tearing outlet. You may also do so. Furthermore, the flow rate resistor is not limited to the open foam shown in the example above. , members that allow liquid to permeate and flow, such as non-woven fabrics and loosely woven or knitted fibrous materials etc.

[0026] In Fig. 3, the seal parts 2, 3, and 4 are formed so that the outer shape of the container 1 is approximately oval. FIG. 4 shows an example of a container of the present invention in which a flow rate resistance part is not formed in the chamber 10. The shape of the seal portions 2, 3, and 4, which have the internal shape of An example of a container of the present invention whose shape is different from the above-mentioned examples, FIG. 5 shows the outer shape of the container 1. This figure shows an example of the container of the present invention in which the top and bottom are formed into a substantially symmetrical diamond shape. Ru. Here, in the containers shown in FIGS. 3 and 5, the tongue-like extension is There is no need to form separately.

[0027] The container of the present invention described above has two or more containers arranged in parallel in the length direction, It may be provided in a laminated structure on the thickness side. In this way, containers can be constructed in multiple rows or in multiple rows. With a layered structure, the container of the present invention can contain two or more paste-like substances, such as ketchup. Can be used as a container for dispensing paste and mustard at the same time, or as a container for applying it to the target at the same time. suitable.

[0028]

[Effect of the idea]

The present invention is as described above, and the seal portion is partially sealed by applying pressure to the container. An outlet formed by tearing in a container that is peeled and torn to extrude the contents. is formed by a thin seal line that is approximately bell-shaped or mountain-shaped, and this seal A papillary-shaped peeling protrusion is formed at the top of the line, so it can be removed by applying pressure. In addition to the effect of easily forming an opening for peeling and tearing, it also has the following advantages: There are unique effects such as

[0029] The container of the present invention communicates with the content outlet formed by peeling and tearing the seal part. the non-sealed opening communicates with the outlet so as to form a tongue shape on the outside of the container. Since the opening is formed in the shape of a brush or spatula, the peeling and tearing described above is avoided. The contents extruded from the discharge port of the contents formed by the process are applied to the object of application such as bread. Can be applied as is, i.e. by opening the container and extruding its contents; It is said that the application and supply of the extruded contents to the object can be done with one hand in a series of movements. It has a unique effect. Moreover, you can adjust the amount of application with one hand and apply it as is. This makes it even more convenient.

[0030] As a result, for example, when pasty seasonings such as butter are packed in the container of the present invention, By doing this, jams, butter, etc. can be sold at restaurants, coffee shops, etc. You can save time by dividing the food into smaller portions and dispensing it for each customer. Moreover, it is applied in the container itself. This also has the advantage of not requiring the use of butter knives, spoons, etc.
