Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

SUMMARY OF THE INVENTION The present invention relates to a molded container of the type that sells liquid food products in a sealed form and allows consumers to eat the contents without transferring the contents to another container. Provided is a sealed container for liquid food with a novel structure that has been devised so that the liquid food as a content does not overflow from the container when the flat hermetic seal enclosing the liquid food is peeled off. What you want to do.

[0002]

2. Description of the Related Art Various factors such as the nuclear family, dual working, and westernization of lifestyles have caused a great change in Japan's food culture. Up to many prepared dishes,
From the traditional Japanese custom of once transferring to a container and eating it, it has shifted to the style of eating with the molded container prepared at the time of sale, and a wide variety of moldings according to the needs of consumers It has been a long time since ready-to-eat food in containers has been crowding stores.

[0003] Taking up such ready-to-eat foods as ready-made foods, typical instant noodles such as natto, tsukudani, salad, stewed, etc. are themselves juicy or even flow out if present. You can find various kinds of properties, from the kind that does not have it, to the ones whose containers are filled with pickled juice and liquid exuding from food, such as pickles, tofu, tokoro-ten, etc. However, among molded containers that contain foods with different properties, especially for foods with the latter property, so far, when roughly classified, only about two types can be found, and there has been little change. You can see that it is not.

[0004] In the most general structure, the entire periphery of the upper end of the container body 1 'is bent outward in a substantially horizontal shape to form a welding flange 2', and the contents R 'are melted. Wear collar 2 '
After filling to the full, put a flat sealing seal 5 ',
In parallel with the process of pushing out excess contents R 'and removing air, the periphery of the sealing seal 5' is heat-welded to the welding flange 2 'to seal the contents R' in the container. There is a sealed sealed container for liquid food having a structure as shown in the longitudinal sectional view of FIG. This type has a simple structure of the container itself, is easy and inexpensive to manufacture, and employs an inexpensive heat-sealing film as the sealing seal 5 '. Therefore, it has been adopted for various foods as the most economical sealed molded container for liquid foods.

[0005] However, in the case of the container having this structure, there is no problem if the contents R 'do not contain a liquid, or if the contents R' contain the liquid, there is no problem if the contents R 'do not flow out. Other foods that must be hermetically sealed together with the seasoning liquid, or foods such as pudding and tofu that ooze moisture from the food itself are sealed and provided, and when the consumer peels off the sealing seal 5 ', a considerable amount of Even if you pay attention,
Due to the reaction of the force when the welded portion of the sealing seal 5 'is forcibly peeled off from the welding flange 2' of the container body 1 ', the liquid filled up in the container overflows and the area is soiled. Consumers should choose a place where they can handle the situation in advance, such as starting work on a saucer or holding it on a sink sink. With the complication that the sealing seal 5 'must be peeled off, the container was not welcomed by consumers in that respect, and the provisional liquid could be opened without spilling. However, it was impossible to add soy sauce, syrup, or other seasonings unless it was possible to stir thereafter.

[0006] Because of these disadvantages, there is a sealed molded container for liquid food, which has been developed and provided to solve these problems and has a structure as shown in an enlarged sectional view of a main part of FIG. That is, the entire lower periphery of the welding flange 2 'formed at the upper end is slightly squeezed inward to form a container body 1' having a stepped portion 11 ', while the contents R' are sealed. For this reason, the entire periphery of the welded peripheral edge C1 for mounting and welding on the container body welding flange 2 'is welded to the container body stepped portion 11'. An inverted hat-shaped molded lid C having a shallow cross-section formed by forming a pressed lid C2 depressed to a depth such that the contact is formed,
After the quantified contents R 'are filled up to the full height of the step portion 11' of the container body 1 ', the molding lid C is covered, and the peripheral portion of the pressing lid portion C2 is placed on the step portion 11'. In the process, while the air is pushed out by slightly pressing the surface of the contents, the peripheral edge portion C1 to be welded is welded to the flange portion 2 'for welding the container body and sealed. It is a hermetically sealed container for liquid food having the above structure.

[0007] In the case of a liquid food food sealed mold container having this structure, even if the welded peripheral portion C1 of the molded lid C is forcibly peeled off from the container body welding flange 2 'and opened, the contents R are not removed. ′ Itself is regulated and accommodated in a portion lowered from the upper end of the container body 1 ′ to the step portion, and the upper peripheral wall portion of the container body 1 ′ above the step portion 11 ′ is placed on the contents R ′. Because of the existence, even if the liquid of the contents R 'is considerably shaken by the reaction when the temporary lid C is opened, there is no possibility of overflowing from the container body 1', and the above structure is the most general structure. Evils such as liquid food sealed molding can be reliably wiped off, and are extremely easy to handle,
The result is a consumer-friendly container.

However, this type of container has the following structural problems not found in the above-mentioned container. One of these is that, first of all, in the case of this container, a film cannot be used unlike the container having the above-mentioned structure, and a sealing molded lid C specially manufactured by a plastic molding machine is separately prepared similarly to the container main body. And the second problem is that the cost of the container alone is high, and the second problem is that, in the sealing process, the molded lid C and the container body inside from the welding point are welded. The 1 'upper peripheral wall portion is merely in the attached state, and as a result of being combined with a structure having a gap, no matter how accurately the contents R' are quantified and filled, As long as a step of pressing the hollow structure portion of the molded lid C against the surface of the content and bleeding air is required, the content R 'is to be pushed into the above-mentioned gap portion, so that the portion is not mottled. Of contents in state Part, the appearance is extremely poor if the container is transparent or translucent. Even if a container made of provisional opaque material is used, the contents R Part of the container body 1 'sticks to the upper peripheral wall portion of the container body 1', resulting in an unsightly state. In any case, there is a disadvantage that the commercial value is reduced.

[0009] In view of the above-mentioned current situation of this type of hermetically sealed molding for liquid foods, the present invention is based on the fact that the business related to food production and sales has been a living business for many years, Unsatisfied with these provided containers, I realized the need to develop containers based on the viewpoint of providing foods that are welcomed by consumers, and developed from various angles,
As a result of conducting research and repeating many trial and error and trial production experiments, we finally completed and commercialized a liquid food sealed mold with a new structure that can achieve the intended purpose. In the following, all of the configurations will be described in detail together with some embodiments.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The sealable molding for liquid foods of the present invention, as can be easily understood from several typical embodiments shown in the drawings, has the following features. Things. That is, the seal welding flange is integrally formed substantially horizontally outward from the entire periphery of the upper end of the container body,
A peripheral wall portion having a predetermined height directed upward or obliquely upward toward the outside is integrally formed on the entire outer peripheral edge of the seal welding flange portion, and is formed as a flat seal made of a heat-sealed film. The seal periphery is welded onto the seal welding flange and sealed in the container body without being related to the peripheral wall rising from the container body seal welding flange. This is a hermetically sealed container for liquid food in which an overflow prevention space is secured above the hermetic seal.

In other words, a seal welding flange portion is integrally formed substantially horizontally outward from the entire periphery of the upper end of the container body, and is formed around the entire outer peripheral edge of the seal welding flange portion. Is formed integrally with a peripheral wall portion of a predetermined height facing directly upward or obliquely upward toward the outside, and forms a flat hermetic seal periphery made of a heat-sealing film into a container main body seal welding flange periphery. Irrespective of the peripheral wall rising up from above, by welding on the seal welding flange and sealing the contents in the container body, the container body seal welding flange is placed on the flat sealing seal. It can be said that it is a sealed molded container for liquid food in which an overflow prevention space surrounded by a peripheral wall rising from the peripheral edge is secured.

Further, according to a more specific description, a seal welding flange portion is formed integrally and substantially horizontally outward from the entire periphery of the upper end of the container body, and the seal welding flange is formed. On the entire outer periphery of the portion, a peripheral wall portion of a predetermined height directed straight upward or obliquely upward toward the outside is integrally erected and formed, and a flat hermetic seal periphery made of a heat-sealed film is formed into a container. By being welded on the seal welding flange and sealing the contents inside the container body without being concerned with the peripheral wall rising from the peripheral edge of the body seal welding flange,
On a flat hermetic seal, a sealable container for liquid food is provided which has an overflow preventing space directly surrounded by a peripheral wall rising from the periphery of the flange for welding the container body seal. Can provide a summary.

The container body is made of a liquid food, that is, a liquid or a liquid that is dissolved in a liquid itself, such as juice, yogurt, ice cream, or the like, or a solid substance mixed in a liquid, such as a pulp juice. Including, bean bean, tokoroten, foods such as pickles such as pickled, solid or jelly-like, impregnated or coated with various liquids, and those liquids exude from the surface, such as tofu and Egg tofu, pudding, and other similar foods, and solid foods that are slightly out of the meaning of the wording but are later poured into liquids such as boiling water and seasoning liquid to contain liquids,
For example, containing food such as cup noodles, sold as it is or in a state where it is appropriately packaged, after the consumer has purchased and peeled off the sealing member to expose the contents upward, It is a water-resistant material that functions as a tableware itself, or as a container for a certain period of time while leaving the contents until it is eaten,
In addition, it must be a material that can be sealed with a known heat-sealing film using the same heat-sealing means as before, and can be made of plastics, resin-coated paper, metal, or metal curtains. It can be formed from any material that has been conventionally used for this type of sealing, such as laminated paper, and its three-dimensional shape is not particularly limited, and can be variously selected from functions, applications, design purposes, etc. It is possible to adopt various shapes.

[0014] From the entire upper edge of the container body,
A welding flange portion extending substantially horizontally outward is formed integrally with at least a width (not necessarily equal width) that enables welding processing over the entire circumference. Further, the outer peripheral edge thereof is a peripheral wall portion having a structure formed by bending so as to have a predetermined height in a direction directly above or slightly inclined upward and outward, Both the seal welding flange portion and the peripheral wall portion are integrally formed by molding when the container body is formed.

The hermetic seal is formed from a flat heat-welded film cut into a shape substantially corresponding to the outer periphery of the seal welding flange portion of the container body, and is filled up to the full seal welding flange portion of the container body. Along with the surface of the contents, the peripheral portion is placed on the flange portion for sealing welding, and is then welded by a known welding means to perform a function of sealing various contents filled in the container body. At the same time, after reaching the consumer's hand, the peripheral portion must be peeled off from the seal welding flange in order to eat the contents, which is convenient for peeling. Looks good,
For example, as shown in an embodiment described later, a part of the peripheral portion of the hermetic seal is formed at one or a plurality of locations, a tongue-like knob that protrudes outward, or the hermetic seal itself is used. , Shall be cut into a shape larger than the outer periphery of the seal welding flange, and those knobs or large portions that are outside the portion welded on the seal welding flange and remain unwelded It is desirable to simply bend the peripheral portion of the peripheral wall portion inside the peripheral wall portion of the overflow prevention space portion so as to be attached to the peripheral portion portion, and to have a structure that also has a peeling function.

The spill-prevention space is surrounded by a peripheral wall that rises in the direction in which the entire outer peripheral edge of the seal welding flange is inclined upward or slightly upward. After the sealing seal is peeled off, it is formed in advance above the hermetically-sealed sealing seal, allowing the contents or the contents to which the seasoning liquid or the like has been added to rise, and the contents overflow from the container body. It functions as a space to prevent it from getting stuck, and has a structure in which the peripheral wall part that rises continuously from the seal welding flange formed integrally with the upper end edge of the container body remains facing upward (However,
The upper edge should be provided with a protective edge treatment such as a rounded structure, a thick structure, and a folded structure all around. ) Or, furthermore, the entire periphery of the upper edge is outwardly bent and extended substantially horizontally to form a reinforcing edge, or the entire periphery of the reinforcing edge is bent and formed downward. It is also possible to form on the reinforcing edge of the structure reinforced by the auxiliary edge.

The peripheral wall, which is necessary for forming the overflow preventing space, needs to be set so as to increase as the viscosity of the contents decreases, and it is also necessary to set a size such as syrup, soy sauce, vinegar or the like. In the case of adding a seasoning liquid or the like to the contents in the container body later and eating it, the amount of the added seasoning liquid or the like must be taken into consideration, and further,
After the seasoning liquid is added, it is necessary to adjust the height depending on whether it is necessary to stir with the contents. Besides, the overflow prevention space is made of simple dishes such as spoons and hawks, and various seasonings. If the space also serves as a storage space for materials, instructions, etc., the height must be optimized in consideration of their volume.

The spillover prevention space formed in this way has a structure in which a hermetic seal is welded to the seal welding flange, and the contents are sealed in the container body (therefore, the peripheral edge protrudes upward). In the case of products that have a reinforcing edge on the peripheral edge, in order to seal the contents once, a sealing seal is welded to the sealing welding flange, and a separate sealing seal is used. The outer peripheral edge of the container is welded to the reinforcing edge to form an overflow prevention space enclosed by the sealing seal, or the outer periphery of the container main body including the seal seal welding flange portion and the peripheral wall portion is heat-shrinkable. By tightly packing, it is also possible to form an overflow prevention space portion sealed by the heat shrinkable film, and it is possible to form the sealed overflow prevention space portion. In this case, the overflow prevention space can be used also as an accommodation space in which an additive or a mixture such as a seasoning liquid or a condiment, or a simple dish such as a spoon or a printed matter such as a manual can be loaded. It can be very convenient. Hereinafter, some of the illustrated embodiments will be described in order to further clarify the configuration of the present invention described above.

[0019]

Embodiment 1 The embodiment shown in the vertical sectional view of FIG. 1 is the most typical case having the basic structure included in the present invention. The container main body 1 is a flat circular container whose bottom is formed to have a reinforced cross-sectional structure, and its entire upper edge is about 3 to 5 mm (interfering with heat sealing with a sealing seal described later). The width of the seal welding flange 2 is extended substantially horizontally so as to extend outward.
And the entire outer periphery is bent in a direction directly above to about 5
mm (If the viscosity of the contents or the seasoning liquid is to be added later, the height should be set to the optimum height considering the overflow of the contents, such as the amount and necessity of stirring.) (There is no restriction.) To form a peripheral wall portion 4, and the container body 1, the seal welding flange portion 2, and the peripheral wall portion 4 are integrally injection-molded by a plastic molding machine. The upper edge of the peripheral wall portion 4 is not necessarily clear in the drawing, but has a rounded structure for safety.

The desired liquid food R is placed in the container body 1 including the seal welding flange 2 and the peripheral wall 4 thus formed.
Is filled up to the seal welding flange 2, and a flat sealing seal 5 made of a separately prepared heat-sealing film is used to seal the peripheral portion of the liquid food R together with the surface thereof on the sealing welding flange 2. The peripheral portion of the hermetic seal 5 and the sealing flange 2 are heated and welded while being pressed downward so as to push out any excess content from the surface of the liquid food R together with air, if any. When the contents are sealed in the container body 1, the liquid food hermetically sealed molding of the present invention in which the overflow preventing space 3 is formed in the portion of the sealing seal 5 surrounded by the peripheral wall 4 is provided. Is achieved.

In the drawing, reference numeral 51 denotes a knob which serves to peel off the hermetic seal 5 which has been heat-welded and is in close contact with the seal welding flange portion 2 at the consumer stage. One or more places in place of
Is formed so as to protrude outward from the peripheral edge of the peripheral wall portion 4, and is attached to the inner side of the peripheral wall portion 4 without being thermally welded. A product in which the liquid food R as the content is sealed in the container main body 1 in this structure is sold as it is, and from the viewpoint of hygiene, the seal welding flange 2 and the peripheral wall 4 Can be sold with the entire outer periphery of the container body 1 including the heat-shrinkable film, or the outer peripheral wall portion 4 covered with a paper, plastic or other shallow cap or the like.

[0022]

Embodiment 2 The following is an example of an enlarged sectional view of a main part of FIG. 2, which is another typical example which can be adopted as a structure in which a protective end treatment of a peripheral wall portion 4 for an overflow prevention space portion 3 is performed. In the case of (a), the predetermined width of the upper edge is approximately 18
This is a typical embodiment in which the upper end is rounded by 0 ° inversion bending processing so as to also serve as a reinforcing structure. In the enlarged cross-sectional view of the main part of (b), only the upper end edge is used. This is another typical embodiment in which a portion having a thicker portion than other portions is rounded to have a structure having both safety measures and reinforcement measures. As can be easily understood from these embodiments, the peripheral wall portion 4 has a shape of an upper end edge thereof so as not to injure or injure a human body or peripheral equipment, and is made of a plastic mold. Including all other shapes that can be formed, and in some cases, separately, for example, a U-shaped cross-section or other edge member covered or adhered to achieve the purpose, etc.
It is encompassed by the concept of protected edge treatment of the present invention.

[0023]

Embodiment 3 An enlarged sectional view of a main part of FIG. 3 shows a typical embodiment in which the upper edge of the peripheral wall 4 is formed on a reinforcing edge 41. FIG. First, in the case shown in (a), the entire periphery of the upper end edge of the peripheral wall portion 4 is extended substantially horizontally outward by a predetermined width to form the reinforcing edge portion 41, and the strength of the peripheral wall portion 4 is increased. Therefore, it is effective when the wall thickness of the peripheral wall portion 4 itself is thin.
As shown in (b), in the case where the outer peripheral edge of the reinforcing edge portion 41 is bent further downward to have the auxiliary edge portion 42, a more reinforcing effect can be obtained. In the drawings shown as this embodiment, these reinforcing edges 41
Alternatively, the reinforcing edge 41 having the auxiliary edge 42 and the peripheral wall 4
Does not have any structural correlation with whether it has a structure extending directly upward from the seal welding flange portion 2 or a structure inclined toward the outside, and is merely a group based on convenience in the figure. It is just a matching structure.

[0024]

Embodiment 4 As can be understood from the longitudinal sectional view of FIG. 4, this embodiment is carried out by using the reinforcing edge 41 of the peripheral wall 4 of the reinforced structure taken up in Embodiment 3 described above. This is a typical embodiment for realizing the overflow prevention space portion 3. That is, in order to seal the liquid food R as the contents, first, the sealing seal 5 is heat-welded to the seal welding flange 2 and the outer peripheral edge of the separate sealing seal 6 is reinforced by the reinforcing edge 41.
In this case, the overflow preventing space 3 is sealed by the sealing seal 6. In other words, the heat sealing means for the sealing seal 5 and the sealing seal 6 is performed twice. This is to form an overflow prevention space 3 which is shielded from the outside world. Therefore, the overflow preventing space 3 is maintained in a sanitary manner until the sealing seal 6 is peeled off.

Although not shown, instead of welding the sealing seal 6 to the reinforcing edge 41, the outer periphery of the container body 1 including the seal welding flange portion 2 and the peripheral wall portion 4 is conventionally removed. Also by tightly packing with a heat shrink film that is generally adopted, the heat shrink film is similarly
It is also possible to form a sealed overflow prevention space portion 3 and, as employed in the fifth embodiment shown in the enlarged sectional view of the main part of FIG. 5, a relatively shallow paper cap 7 is covered with a cap. With this configuration, substantially the same overflow prevention space 3 can be realized.

[0026]

Fifth Embodiment FIG. 5 is an enlarged cross-sectional view of a main part showing an embodiment characterized by the peripheral structure of the sealing seal 5. The sealing is formed so as to be larger than the contour shape of the sealing flange 2 for welding. Using the seal 5, leaving a margin around the seal 5
The heat sealing is performed on the upper surface, and the peripheral edge of the surplus sealing seal 5 is merely attached to the inner side of the peripheral wall portion 4. In this embodiment, the case where the plane shape of the peripheral wall portion 4 is circular is shown,
The sealing wall 5 is formed on the peripheral wall 4 inclined slightly outward.
The peripheral edge is made to easily adhere to the inner side of the peripheral wall portion 4, and the sealing portion 5 originally formed of a flat heat-welding film is also forcibly formed by the peripheral edge portion protruding from the seal welding flange portion 2. As a result of being welded to the portion which comes into contact with the seal welding flange portion 2 while being pressed along the inner side of the peripheral wall portion 4, the inner side from the welded portion is maintained as an original flat surface, but welding is performed. As shown in the drawing, the portion outside the portion has a structure in which irregular folds are generated over the entire circumference, and as a result, the portion is partially separated from the peripheral wall portion 4 at various places, and is easily peeled from anywhere. The structure as described above is realized, and as in the case shown in the first embodiment, a special knob 51 is prepared, and only the portion is welded and sealed.
This is an example of trying to resolve the inconvenience that makes it impossible to remove.

As described above, according to the present invention, the hermetic seal 5
A part of the sealing wall 5 is attached to the peripheral wall portion 4, but the sealing seal 5 is surely welded onto the seal welding flange portion 2 irrespective of the relation with the peripheral wall portion 4. It must be formed in such a way that the mounted structure can be realized. The molded lid shown in FIG. 7 is employed as having a function of sealing the fold portion of the hermetic seal 5 in addition to a function of sealing the overflow prevention space 3.

[0028]

According to the sealable molding for liquid food of the present invention having the above-described structure, the peripheral wall is provided over the entire periphery of the upper edge of the container body which is higher than the hermetically sealed seal of the liquid food. As a result, a structure in which an overflow prevention space portion is secured above the surface of the liquid food is realized, so that the consumption such as that shown in FIG. When the person peels off the sealing seal 5 ',
It is possible to surely avoid the unexpected itself, such as the reactionary spilling of the liquid food that is the content, and the liquid food is eaten by adding a predetermined condiment, seasoning, or seasoning liquid. Even without transferring to another container, spices and seasonings, seasoning liquid is added using the molded container as it is, and furthermore, it has an excellent feature that it can be stirred, furthermore, Unlike the conventional liquid food container having the structure shown in FIG. 7, no specially formed molding lid C is required at all, and the sealing seal 5 made of a heat-sealing film, which is the simplest sealing means, is used. Since the heat-sealing and sealing process can be performed by the simple structure and means used, the harmful effects such as the high unit cost of the container and the deterioration of the sealing condition, as in the past, can be completely eliminated. When it is done It has become what can be obtained significant advantages.

As described above, in the present invention, the conventionally known molded containers for liquid foods are all based on the technical idea of heat sealing and sealing at the uppermost part of the container. , Heat-sealing, because it employs a revolutionary means of setting the sealed location at a location that is lower than the top of the container by a predetermined dimension, it is clear that the technical idea and the previous one The difference between the two is that the most practical containers for consumers are:
This kind of container can be realized by the simplest and most economical means for hermetically sealing. This kind of container can realize a container having a substantially ideal configuration.

In particular, the container shown in the first embodiment is the container which can most easily realize the constitution of the present invention, and the sealed container for liquid food of the second embodiment has a reinforced structural strength. Thus, a container having high durability can be realized, and the structure shown in Embodiment 3 has a high added value that a new accommodation space can be obtained in addition to consideration of hygiene. This is a container, which has the advantage that it can be applied to various liquid foods, and furthermore, in Example 4, it is possible to exhibit characteristics that are not easy to handle in other examples. ing.

As described above, the sealed molded container for liquid food of the present invention is formed into a structure that is extremely convenient for consumers as a molded container for liquid food, and is a production method for instantly converting this kind of liquid food into food. Many sellers also enjoyed the advantage of being able to enjoy the advantages of being able to offer products that are inexpensive, have a good appearance, and have added value by adopting almost the same manufacturing process as before, and are highly valued by many people. It is expected to be widely adopted and greatly spread.
