Abstract

PROBLEM TO BE SOLVED: To facilitate the taking out of various kinds of fluid foods, eliminate a residual food in the container, and at the same time, enhance the forming efficiency of the container by a method wherein a bar-shaped body which extends in the container with the tubular suction port of the bag-shaped container as a base, constitutes a passage for drawing which communicates with the suction port, along with the internal surface of the container. SOLUTION: When a food is drawn from a mouth part 22, as the liquid level of the food descends, the internal surfaces of a container main body 1 come closer to each other between the lower opening edge part 25 of a bonding part 21 and the liquid level of the food, and a bar-shaped body 3 resists a deformation by contraction of the container main body 1, and prevents the internal surfaces from joining to each other, and ensures a passage for the drawing of the food between the end edge 32 of a rib 31 which is the external surface of the bar-shaped body 3, and the internal surface of the container main body 1. When a residual amount of the food becomes less, and the container main body 1 is further deformed by contraction, the internal surface of the container main body 1 comes into contact with the bottom of the end edge 32 of the rib 31, and a passage A for drawing is constituted between both ribs 31. For this reason, regardless of the residual amount in the container, the food can be introduced to a tubular suction port 2 by making it pass through the passage A for drawing.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a food container,
More specifically, the present invention relates to a food container for filling liquid foods such as juices, sports drinks, jelly-like favorite items, soups, and gruel.

[0002]

2. Description of the Related Art Conventionally, for example, a bag-shaped container main body is formed of a flexible sheet in which an aluminum foil is used as a core material and synthetic resin films are laminated on the front and back thereof, and the synthetic resin is formed so as to close an opening of the container main body. A food container having a spout attached thereto is used. Further, a straw is known in which a straw that extends toward the inside of the container body is connected to the mouth in advance, and the fluid food filled in the container can be sucked from the straw. At the connection between the straw and the mouth, an opening is formed for introducing the remaining food to the mouth by tilting the container, and this opening is initially sealed on the inner surface of the container body and the container is tilted when the container is tilted. The inner body surface is separated from the opening to release the sealing, and the remaining food can be taken out of the container without being left.

[0003]

In the above-described food container, when a straw extending from the mouth is injection-molded with a synthetic resin, a slide pin is inserted into and pulled out of a split mold. Since the time required for cooling the pulled-out slide pin occupies a considerable proportion, the molding efficiency is lowered. In addition, an opening is formed at the connection between the straw and the mouth in order to lead the remaining food from the mouth.If this opening is large, the inner surface of the container body separates from the opening while holding the container. As a result, the seal is accidentally released, and it becomes difficult to suck the food from the lower end of the straw. Conversely, if the opening is small, it becomes difficult to take out foods having relatively low fluidity, such as jelly-like favorite items, soups, and gruel.

[0004] It is an object of the present invention to provide a food container which can be easily taken out of various fluid foods, can be taken out of the container without leaving the remaining food, and has high molding efficiency.

[0005]

According to the present invention, there is provided a bag-like container formed of a flexible sheet for storing a flowable food,
A tubular suction port that is sealed at the sealing portion of the container and can communicate with the outside, and a rod-like body extending into the container with the suction port as a base, wherein the rod-like body is between the inner surface of the container and A food container characterized by being able to constitute a suction channel communicating with the suction port.

According to the present invention, a bag-shaped container formed of a flexible sheet for storing a flowable food, a tubular suction port which is sealed at a sealing portion of the container and can communicate with the outside, and It consists of a rod-like body extending into the container as a base,
A food container is provided, wherein the rod-shaped body can form a suction channel communicating with the suction port between the rod and an inner surface of the container.

The flexible sheet according to the present invention includes:
Preferably, it is compatible with the food to be filled, is easy to dispose and recycle, is not easily torn by external force, and has an appropriate shape retention. Specifically, a film obtained by heat-sealing a film made of a synthetic resin, for example, a film of polyester, polyethylene, polystyrene, polyvinyl chloride, stretched nylon, or the like on the front and back of aluminum foil as a core material can be used.

The liquid food in the present invention includes drinks such as juices and sports drinks, jelly-like drinks, liquid foods such as soups and porridges, and other portable foods such as space foods, and noodle soups, sauces and sauces. Types of seasonings are included. The bag-shaped container in the present invention is preferably a container formed of a flexible sheet and shrunk and deformed in response to the removal of the food without being easily ruptured by external pressure in a state where the food is filled. More specifically, a flat bag, generally called an envelope, a gusset bag with gussets on both sides of the bag, a turtle shell with no gusset, and a hexagonal bottom, and a hexagonal corner with gussets on both sides of the bag A bottom bag is mentioned, and among them, a gusset bag or a square bottom bag having gussets on both sides of the bag is preferable.

In the present invention, the tubular suction port is a short tube portion formed on a part of the bag-like container, preferably on the sealing side of the flexible sheet, and more preferably the outer periphery is formed on the sealing side. A tubular member that is fixed inside and has an inner periphery that forms a flow path of food, and the inner diameter is set according to the physical properties and fluidity of the food. The suction port is provided with a stopper that seals the food filled in the container and can be opened at the time of taking out the food, and this stopper does not easily come out of the suction port due to external pressure or internal pressure such as coagulation of food or thermal expansion. desirable. Specifically, a screw cap having a return torque to the suction port of 1.5 kgf or more is preferable.

In the present invention, the rod-shaped body is connected to the lower end of the suction port (open end in the container) without closing the suction port, and cooperates with the container body to form a gap between the outer surface and the container inner surface. Secondly, it is means for securing a flow path for leading out the food filled in the container to the suction port. Specific examples of the cross-sectional shape of the rod include a circle, an ellipse, a semicircle, a rectangle, a polygon, a circle, a split circle, and those in which ribs are formed.

[0011] The suction channel in the present invention means that when the food filled in the container is sucked through the suction port, the outer surface of the rod-shaped body and the inner surface of the container are opposed to the container body that contracts and deforms when the food is taken out. Refers to a tubular channel formed therebetween. The rod-shaped body is composed of a shaft and a group of ribs extending radially from the shaft (or the axis), and the inner surface of the container abuts the end of an adjacent rib to form a suction flow path between the two ribs. Is preferred.

The group of ribs in the present invention refers to a container which shrinks and deforms by taking out food, in order to prevent the inner surface of the container from sticking around the axis of the rod when sucking the food filled in the container from the suction port. It acts as a spacer for forming a suction flow path between the outer surface of the rod and the inner surface of the container against the main body, and the shape that connects the ends of the ends of the ribs extending radially is used. Those that form a polygon are desirable.

In particular, it is preferable that ribs composed of long pieces and short pieces are orthogonal to each other so that the above-mentioned shape forms a "rhombic shape". In such a case, the direction of the long piece and the short piece or the ratio of the length of both pieces may be determined according to the aspect ratio in the cross-sectional shape of the bag-shaped container.

Although it has a special shape, even if it has a "H" shape or an "I" shape in which two ribs extend in opposite directions, that is, a rod-like body made of a flat plate, the container body and In cooperation, that is, it is possible to form a suction flow path between the specified outer surface of the rod and the inner surface of the container by placing the shrink deformation of the container body in the pre-oriented container. For example, the shape of the rod is not limited to the above.

Preferably, the rib further comprises at least one branch rib branched from the end side or side surface or from the end side or side surface. The branch rib in the present invention refers to a rib whose base is off the axis of the rod-shaped body and which branches off in a “comb” shape from the axis. It is desirable that the rod-like body has one end fixed with the suction port as a base, thereby serving as a posture holding means for holding the posture of the suction port when gripping the container.

[0016] The posture holding means in the present invention means that when the container body is gripped, a rod-like body extending into the container from the suction port serves as a core material of the container and assists in maintaining the shape of the container. And means for guiding the attitude of the suction port fixed at the tip of the rod-shaped body via the container, that is, the opening direction to a direction suitable for suction. This measure also works effectively in automatic packaging including food filling.

It is desirable that the rod has a base formed with an opening large enough to allow the food sealed in the container to flow into the suction port when the container is tilted. The opening in the present invention is formed so that when the container is tilted, the food remaining in the container is drawn out from the suction port. Specifically, the opening of the suction port at the connection portion (base) between the rod-shaped body and the suction port is formed. As expected.

In the food container according to the present invention, when the food is taken out from the food container in which the food is sealed, the suction port is unsealed and the food is sucked from the suction port. At this time, the container body contracts and deforms so that the inner surfaces of the suction port and the food come into close contact with each other due to the reduced pressure and closes a portion immediately below the suction port, but the rod-shaped body resists the contraction deformation of the container body. The suction flow path can be formed between the outer surface of the rod-shaped body and the inner surface of the container while preventing the close contact between them. For this reason, regardless of the remaining amount of the food, the food passes through the suction channel and is drawn out from the suction port.

The rod-shaped body is composed of a shaft and a group of ribs extending radially from the shaft (or the axis). The inner surface of the container abuts on the edge of the adjacent rib, and a suction flow is provided between the two ribs. If it constitutes a passage, when suctioning the food filled in the container from the suction port, the inner surface of the container is prevented from sticking around the axis of the rod-shaped body, thereby resisting the container body that shrinks and deforms. In other words, between the outer surface of the rod and the inner surface of the container,
In this case, a suction flow path can be formed between the inner surface of the container and the two ribs that are in close contact between the ends of the two adjacent ribs.

If the rib further comprises at least one branch rib branched from the end and / or side surface thereof, the shape of the container or the remaining amount of food in the container is reduced in cooperation with the container body. It is possible to form a suction flow path according to a plan.

If one end of the rod-shaped body is fixed to the suction port as a base to form a posture holding means for holding the posture of the suction port when gripping the container, the rod-shaped body may be fixed when the container body is gripped. A rod extending from the suction port into the container serves as a core material of the container to assist in maintaining the shape of the container. At this time, the rod fixed via the container in the palm of the hand is attached to the tip of the suction. The posture of the mouth can be guided in the suction direction. If the rod has a base formed with an opening large enough to allow the food sealed in the container to flow to the suction port when the container is tilted, the remaining food in the container is sucked when the container is tilted. Can be derived from the mouth.

Since at least one of the ribs forms a taper tapering toward the end at the end thereof, a suction passage having a relatively small cross section can be formed at the bottom of the container. The suction force reaches the bottom of the container, and the food can be sucked with a small suction force. The rib is composed of a pair of long pieces extending in the dorsal direction from the shaft and a pair of short pieces extending in the dorsal direction from the shaft and orthogonal to the pair of long pieces. If the rod-shaped body is extended in the container so as to be parallel to the sealing side of the container, a suction flow path according to the shrinkage deformation of the bag-shaped container can be formed.

[0023]

1 to 4 show a food container according to one embodiment of the present invention. The food container 10 includes a container main body 1 formed of a flexible sheet, a tubular suction port 2 sealed at a sealing portion of the container main body 1 and capable of communicating with the outside, and extending into the container using the suction port 2 as a base. And a rod-shaped body 3 to be provided.

The container body 1 is a gusset bag having a gusset 11 on both sides and has a flexible structure made of a laminated film of a polyester film, an aluminum foil, a stretched nylon film, and a polyethylene film. At the upper sealing side 12 of the container body 1, a tubular suction port 2 is provided.
Is fixed.

The tubular suction port 2 is a synthetic resin tubular member which is integrally sealed with the container body 1 when the sealing side 12 is sealed and the inner periphery of which forms a flow path for food. As shown in FIG. 3, the outer periphery is composed of a joint 21 hermetically sealed inside the upper sealing side 12 and a mouth 22 extending upward from the joint 21 with the same inner diameter. The mouth 22 has a screw portion 23, and a cap 24 can be attached to the screw portion 23. The rod 3 is thermally welded to the lower end of the joint 21.

When the tubular suction port 2 is fixed to the container main body 1 at the sealing side 12, the lower end of the rod 3 is located near the center of the container body 1 in the height direction or below the center. It is set to the length located at. As shown in the vertical cross-sectional view of FIG. 3, there are ribs 31 extending radially from the axis (or axis) at substantially equal angular intervals in four directions, and each rib 31 has substantially the same width along the axis. And a thickness (equal cross). Edge 32 of adjacent rib
Is configured such that when the container body 1 is contracted and deformed, it comes into contact with the inner surface thereof to form a suction channel between the two ribs 31.

The upper end (base) of the rod 3 is inserted into the inner periphery of the joint 21 through the upper end of the side 32 of the rib 31, whereby the lower opening edge 25 of the joint 21 is An upper opening 4 is formed between the rod 3 and the axis thereof by dividing a surface orthogonal to the axis by the ribs 31 into four groups. This upper opening 4
Is formed in such a size that the food can flow into the mouth portion 22 when the food enclosed in the container is tilted, thereby facilitating the removal of the food having relatively low fluidity.

The method of use and operation of the container body 1 will be described.
When taking out pre-filled food from the container 10 through the mouth 22, the cap 24 is first removed. Since the cap 24 is configured to be released with a return torque exceeding 1.5 kgf between the cap 24 and the threaded portion 23, the filled food can be removed from the container 1.
It does not leak easily from zero. When the food is sucked through the mouth 22, the liquid level of the food decreases and the joint 2
1 between the lower opening edge 25 of the container 1 and the liquid level of the food.
The container body 1 contracts and deforms in the direction in which the inner surfaces of the container approach each other and narrows the food suction channel formed immediately below the upper opening 4, but the rod-shaped body 3 resists the contraction deformation of the container body 1. Adhesion between the inner surfaces is prevented, and a suction channel (not shown) can be secured between the outer surface of the rod-shaped body, that is, between the end 32 of the rib 31 and the inner surface of the container body 1.

As shown in FIG. 4, even when the remaining amount in the container body 1 is further reduced and the container body 1 contracts and deforms,
Since the inner surface of the container body 1 abuts on the edge 32 of the adjacent rib 31 below the edge 32 of the rib 31, and the suction channel A can be formed between the two ribs 31, the food is stored in the container. Irrespective of the remaining amount, it is led out to the suction port through this suction channel.

When the remaining amount in the container body 1 is small enough to be less than the lower end of the rod 3, the container 10 is tilted so that the lower opening edge 25 of the joint 21 and the rod 3
The food can be taken out by gravity from the upper opening 4 formed between the shaft and the shaft . Even if the upper opening 4 is made larger than before, it does not affect the suction, so that the food with relatively low fluidity can be easily taken out. When the used container 10 is discarded, the volume can be reduced by wrapping the container body 1 around the rod 3,
Easy disposal.

In the above-mentioned rod-shaped body 3, the ribs 31 are equi-crosses, that is, the adjacent ribs 31 are formed with substantially the same width along the axis, but the adjacent ribs 31 are formed of long and short pieces. It may be an equilateral cross-shaped rib (see FIG. 11). If this long piece is arranged so as to match the direction in which the sealing side 12 of the container body 1 extends, it is possible to form a suction channel according to the contraction deformation of the container body 1.

FIGS. 5 to 11 show other embodiments 51 to 57 of the rod 3 usable for the food container according to the present invention.
The cross-sectional shape at the center in the longitudinal direction is shown. Embodiments 51 to 57 are, in that order, an "I" shape, an arc, a six-piece radial shape, an "H" shape, an inequality cross and parallel ribs, an "I" and an "H" shape and an inequality cross. Are shown.

The above-mentioned rod-shaped body is inserted and adhered to the inner peripheral portion of the joint portion 21 through the upper end portion (base portion) of each rib at the time of manufacture. In order to enhance the adhesion of the rod, a portion inserted into the inner peripheral portion of the joint portion 21 may have a configuration different from that of the main body of the rod-like body therebelow. Specifically, for example, the insertion portion of the rod 3 is inserted into the rod 53 (FIG. 7), and the insertion portion of the rod 52 (FIG. 6) is inserted into the center of the inner surface of the arc.
1 (FIG. 5), the insertion portion of the rod 54 (FIG. 8) is replaced with the rod 56 (FIG. 10), and the rod 57 (FIG. 1).
In 1), the inserted portion is transformed into a rod-shaped body 3 (FIG. 3). The above-mentioned insertion portion is connected to the main body of the rod-shaped body by integral molding or separately by bonding. Thereby, the contact area with the inner peripheral portion of the joint portion 21 can be increased, and a robust adhesion state can be obtained.

FIG. 12 is a front view in which a part of the rod 57 of FIG. 11 is omitted.
7 shows an example in which a rib 7 has a taper (FIG. 2 equivalent view).
That is, the rod-shaped body 58 is tapered so as to become thinner toward a set of axially symmetric ribs. Such a taper formed in the rib allows the food to be sucked more reliably by making the long piece parallel to the sealing side of the container body, and a draft angle of the mold at the time of forming the rod-shaped body is formed. , Making molding easier. The taper may be formed by all, for example, all four ribs extending from the shaft.

Here, as shown in FIGS. 1 to 4, a test body in which a fruit juice beverage and a jelly-like food (200 g each) were filled in a container body 1 having a rod-shaped body 3 connected below a mouth 22 was prepared. Ten each were produced, and ten adults ate each specimen. As a result, all 10 persons were able to suck the beverage and food almost without leaving the container body 1. In addition, the food suction channel was not blocked during suction. The rod 3 has a length of 80 mm and a diameter of 10 m.
m, average thickness of rib 31 2 mm, radial width 4 of rib 31 4
mm.

In the present application, a rod-shaped body is extended from the mouth into the food container instead of the straw extending from the mouth into the food container, so that the slide pin can be easily cooled during straw molding. As a result, the cooling time is shortened, and one minute per shot is reduced to 30 seconds or less.

[0037]

In the food container according to the present invention, when the food is taken out from the food container in which the food is sealed, the rod-shaped body prevents the inner surfaces of the container from sticking together against the shrinkage deformation of the container main body. A suction channel can be formed between the outer surface of the body and the inner surface of the container body. For this reason, the food can be led out of the suction port through this suction channel regardless of the remaining amount in the container.

The rod-shaped body is composed of a shaft and a group of ribs extending radially from the shaft or the axis, and the inner surface of the container comes into contact with the edge of the adjacent rib to form a suction flow path between the two ribs. If constituted, when sucking the food filled in the container from the suction port, the inner surface of the container is prevented from closely contacting around the axis of the rod, thereby preventing the rod from being shrunk and deformed. Can be formed between the outer surface of the container and the inner surface of the container, that is, between the inner surface of the container and the two ribs which are in close contact with both ends of the adjacent ribs.

If the rib further comprises at least one branch rib branched from the end side and / or side surface, the shape of the container or the remaining amount of food in the container is reduced in cooperation with the container body. A corresponding intentional suction channel can be formed. If the rod-shaped body forms an attitude holding means for holding the attitude of the suction port when gripping the container by being fixed at one end with the suction port as a base, the suction port is held when the container body is gripped. The rod extending from the inside of the container serves as the core of the container to help keep the shape of the container, and at this time, the rod fixed through the container in the palm of the hand and the posture of the suction port fixed to the tip Can be guided in the suction direction.

If the base is formed with an opening large enough to allow the food sealed in the container to flow through the suction port when the container is tilted, the stick remains in the container when the container is tilted. The food can be led out to the suction opening. According to the present invention,
It is possible to provide a food container that can easily take out various fluid foods, can be taken out of the container without leaving the remaining food, and has high molding efficiency.
