Description

Description Food container

Technical field

The present invention relates to a food container, and more particularly, to a food container for filling a liquid food such as juice, sport drink, or jelly cake, soup, porridge and the like.

Background art

Conventionally, for example, a bag-shaped container body is formed of a flexible sheet in which aluminum foil is used as a core material and synthetic resin films are laminated on the front and back, and the opening of the container body is closed with a synthetic resin. Food containers with mouthpieces (soutouts) are used. It is also known that a straw that extends toward the inside of the container body is connected to the mouth in advance, and that the liquid food filled in the container can be sucked from the straw. . At the connection between the straw and the mouth, an opening is formed to allow the remaining food to be drawn out to the mouth by tilting the container.This opening is initially sealed on the inner surface of the container body and the container is tilted. When the container is opened, the inner surface of the container body is separated from the opening and the sealing is released, so that the remaining food can be taken out of the container without being left.

In the above-mentioned food container, an opening is formed at the connection between the straw and the mouth in order to take out the remaining food from the mouth, but if this opening is large, while the container is being gripped, The inner surface of the main body separates from the opening and the sealing is accidentally released, and the food is Is difficult to aspirate. Conversely, if this opening is small, it will be difficult to remove foods with relatively low fluidity, such as jelly-like luxury items, soups, and gruel.

Also, when a straw extending from the mouth is injection-molded with synthetic resin, the slide bin is inserted into and pulled out of the split mold.However, during the molding time, the time required for cooling the slide pin pulled out of the straw is required. Occupy a considerable proportion of the food, which leads to a reduction in molding efficiency.The problem of the present invention is that various fluid foods can be easily taken out, can be taken out of the container without leaving the remaining food, and the molding can be carried out. It is to provide a food container with high efficiency. Disclosure of the invention

According to the present invention, a bag-shaped container formed of a flexible sheet for storing a flowable food, a tubular suction port sealed at a sealing portion of the container and capable of communicating with the outside, and a base having the suction port And a rod-shaped body extending into the container, wherein the rod-shaped body can form a suction flow path communicating with the suction port between the rod-shaped body and an inner surface of the container. A container is provided.

The flexible sheet in the present invention is compatible with the food to be filled, is easy to dispose and recycle, is not easily torn by external force, and has a suitable shape retention property. Things are preferred. Specifically, aluminum foil was used as the core material, and films made of synthetic resin, such as polyester, polyethylene, polystyrene, polyvinyl chloride, and stretched nylon, were thermally welded to the front and back. Things.

The liquid food in the present invention includes beverages such as juices and sports drinks, jelly-like luxury items, liquid foods such as soups and porridges, and other portable foods such as space foods, and potuyu, Sauces and sauces are included.

The bag-shaped container of the present invention is formed of a flexible sheet and is not easily ruptured by external pressure in a state where the food is filled. Is preferred. 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 bottom with gussets on both sides of the bag A gusseted bag having gussets on both sides of the bag, or a square-bottomed bag is preferred. The tubular suction port in the present invention is a part of a bag-like container, preferably or not. A short pipe portion formed on the sealing side of the flexible sheet, and more preferably a tubular member whose outer periphery is fixed inside the sealing side on the inside and which forms a flow path for food. Yes, 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 when the food is taken out. This stopper can be easily opened from the suction port by external pressure or by internal pressure such as coagulation of food or thermal expansion. Those that do not escape are desirable. Specifically, a screw cap with a return torque to the suction port of 1.5 kgf or more is preferable.

The rod-shaped body in the present invention 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 inner surface of the container. The food filled in the container This is a means for securing a flow path for leading out 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.

In the present invention, the suction flow path means that when food filled in a container is sucked from the suction port, the food shrinks and deforms when the food is taken out. Refers to the tubular channel formed.

The rod-like 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 an adjacent rib, and a suction flow path is provided between both ribs. It is preferable to configure The rib group according to the present invention refers to a container body that 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 suctioning 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 by staking, and the shape connecting the ends of the ends of the radially extended ribs 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 in accordance with the aspect ratio in the cross-sectional shape of the bag-like container.

Although it is a special shape, it has a "H" shape or an "I" shape with two ribs extending in opposite directions, that is, a flat plate Even when the rod-shaped body is made of a rod-shaped body, the specified outer shape of the rod-shaped body is cooperated with the container body, that is, the contraction deformation of the container body is arranged in the pre-oriented container. The shape of the rod is not limited to the above as long as a suction channel can be formed between the surface and the inner surface of the container.

Preferably, the rib further comprises at least one branch rib branched from the edge or side or from the edge and side.

The branch rib in the present invention refers to a rib in which the base of the rib is at a position off the axis of the rod-shaped body and which branches off from the axis in a “comb” shape.

The rod-shaped body has one end fixed with the suction port as a base.-It is desirable that the rod-like body should be a posture holding means for holding the posture of the suction port when gripping the container.

The posture holding means in the present invention means that when the container body is gripped, the rod-shaped body extending into the container from the suction port serves as a core material of the container to assist in shape preservation of the container. This means means for guiding the posture of the suction port, that is, the direction of the opening, in which the rod-shaped body fixed through the fin is fixed to the tip thereof, in a direction suitable for suction. This measure also works effectively for 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 through the suction port when the container is tilted.

The opening in the present invention means that when the container is tilted, it remains in the container. It is formed to guide the food to be discharged from the suction port, and specifically refers to the opening of the suction port at the connection (base) between the rod-shaped body and the suction port.

By the way, the food container according to the present invention releases the sealing of the suction port and sucks the food from the suction port when the food is taken out from the food container in which the food is sealed. At this time, the container body contracts and deforms so that the inner surfaces of the suction port and the food adhere to each other due to the decompression and close the portion directly below the suction port, but the rod-shaped body resists the contraction deformation of the container body. The suction channel can be formed between the outer surface of the rod and the inner surface of the container by preventing the inner surfaces from sticking to each other. For this reason, regardless of the remaining amount of food, the food passes through the suction channel and is discharged 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), and the inner surface of the container abuts the edge of the adjacent rib, and a suction flow path is provided between both ribs. When the food filled in the container is sucked from the suction port, the inner surface of the container is prevented from closely adhering to the axis of the rod-shaped body. In this case, a suction flow path is formed between the outer surface of the rod and the inner surface of the container, that is, in this case, between the inner surface of the container and the two ribs which are in close contact between the edges of both adjacent ribs. If the rib further has at least one branch rib branched from the end and / or side surface, the shape of the container or the food in the container in cooperation with the container body It is possible to form a planned suction flow path according to the remaining amount of water.

In addition, the ribs become pongee at the end If a taper is formed, a suction channel having a relatively small cross section can be formed at the bottom of the container, so that the suction force of the food reaches the bottom of the container and the food can be sucked with a small suction force.

The rod-shaped body is fixed at one end with the suction port as a base. When forming a posture holding means for holding the posture of the suction port when gripping the container, when the container body is gripped. The rod extending from the suction port into the container became the core of the container and assisted in keeping the shape of the container.At this time, the rod fixed in the palm through the container was fixed to the tip end. The posture of the suction port can be guided in the suction direction. If the stick has a base formed with an opening large enough to allow the food enclosed in the container to flow into the suction port when the container is tilted, the remaining food in the container will be sucked when the container is tilted. It can be derived from the mouth. BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 is a perspective view (including a partially cut surface) of a food container according to one embodiment of the present invention, and FIG. 2 is a front view showing a tubular suction port and a rod-like body of the food container of FIG. Fig. 3 is a cross-sectional view taken along the line II-II of Fig. 1 (when the food is full), and Fig. 4 is a cross-sectional view taken along the line III--11 of Fig. 1 (when the food is taken out). 5 to 11 are enlarged cross-sectional views of a rod according to another embodiment of the present invention, and FIG. 12 is a front view in which a part of the rod in FIG. 11 is omitted. BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 4 show a food container according to one embodiment of the present invention. The food container 10 includes a container body 1 formed of a flexible sheet, a tubular suction port 2 sealed with a sealing portion of the container body 1 and capable of communicating with the outside, and the suction port 2 as a base. And a rod 3 extending into the container.

The container body 1 is a gusset bag having gussets 11 on both sides, and is made of a laminated film of a polyester film, an aluminum foil, a stretched nylon film, and a polyethylene film. It has a flexible structure. A tubular suction port 2 is fixed to an upper sealing side 12 of the container body 1. The capacity of the container body 1 can be set in the range of about 0.1 to 1 reel.

The tubular suction port 2 is a synthetic resin tubular member that 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 (1), the outer peripheral portion is composed of a joint 21 that is 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 thread 23, and a cap 24 can be attached to the thread 23. A rod 3 is thermally welded to the lower end of the joint 21. When the tubular suction port 2 is fixed to the container body 1 at the sealing side 12, the lower end of the rod body 3 is located near the center of the height direction of the container body 1 or below the center thereof. It is set to the position length. As shown in the vertical cross-sectional view of Fig. 3, a group of ribs 31 extending radially from the axis (or axis) in four directions at approximately equal angular intervals is used. Each of the ribs 31 is formed to have substantially the same width and thickness along the axis (equal cross). The ends 32 of the adjacent ribs are 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.

Here, the diameter of the rod 3 (the maximum diameter including the tip of the rib 31) can be set in a range of about 5 mm to 3 Omm according to the thickness of the container body 1 when the food is filled. Assuming that the diameter is 10 mm, the average thickness of the rib 31 can be set in a range of about 1 mm to 3 mm, so that the radial width of the rib 31 is about 3.5 in m to 4.5 mm.

The length of the rod 3 can be set in a range of about 30 mm to 300 mm according to the height of the container body 1. The rod-shaped body 3 can be configured such that the lower end thereof comes into contact with the bottom surface (bottom side) of the inside of the container body 1 when the food is filled, but the distance between them is determined by the shape of the container body〗. It is set arbitrarily according to the flexibility.

The upper end (base) of the rod 3 is inserted into the inner periphery of the joint 21 via the upper end of the end 32 of the rib 31, whereby the lower opening of the joint 21 is opened. An upper opening 4 is formed between the part 25 and the axis of the rod 3 by dividing a plane orthogonal to the axis into four groups of ribs 31. The upper opening 4 is formed in such a size that the food can flow into the mouth 22 when the food enclosed in the container is tilted, thereby facilitating the removal of relatively low-flowable food. .

The usage and operation of the container body 1 will be described. When removing the pre-filled food from the container 10 from the mouth 22, first remove the cap 2 Remove 4. The cap 24 is configured to be released with a return torque of more than 1.5 kgf between the thread 23 and the filled food, so that the filled food can easily leak out of the container 10. And not. When the food is sucked from the mouth 22, the inner surface of the container body 1 moves between the lower opening edge 25 of the joint 21 and the liquid level of the food as the liquid level of the food drops. The container body 1 shrinks and deforms in the direction of approaching and narrowing the food suction flow path formed just below the upper opening 4, but the rods 3 pile on the shrinkage deformation of the container body 1 and the inner surfaces Adhesion is prevented, and a suction channel (not shown) can be secured between the outer surface of the rod-shaped body, that is, the end 32 of the rib 31 and the inner surface of the container body 1.

As shown in FIG. 4, even if the remaining amount in the container body 1 becomes smaller and the container body 1 contracts and deforms, the ribs 31 adjacent to the ribs 31 adjacent to the lower part of the edge 3 2 of the rib 31 may be used. The inner surface of the container body 1 abuts against the edge 32, and a suction channel A can be formed between the two ribs 31 so that the food can be suctioned regardless of the remaining amount in the container. After passing through the use channel, it is led out to the suction port.

When the remaining amount in the container main body 1 becomes small enough to be less than the lower end of the rod 3, the container 10 is tilted so that the lower opening 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. 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 disposing of used container 10, wrap container body 1 around rod 3. By squeezing, the volume can be reduced and disposal is easy.

In the rod 3 described above, the ribs 31 are equilateral 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 the long piece and the short piece. It may be an unequal cross-shaped rib consisting of (see Fig. 11). If this long piece is arranged so as to match the direction in which the sealing side 12 of the container main body 1 extends, a suction flow path according to the contraction deformation of the container main body 1 can be formed.

FIGS. 5 to 11 show other embodiments 51 to 57 of the rod-shaped body 3 usable in the food container according to the present invention in a sectional shape at the center in the longitudinal direction. Embodiments 51 to 57 have an "I" shape, an arc, a six-piece radial shape, an "H" shape, an unequal cross and a parallel rib, an "I" and a "H" shape, and Each of the equal crosses is shown.

The above-mentioned rod-shaped body is inserted and adhered to the inner periphery of the joint 21 through the upper end (base) of the end of each rib at the time of manufacturing. In order to enhance the adhesiveness of the joint, the portion inserted into the inner peripheral portion of the joint portion 21 may be configured differently from the main body of the rod-like body therebelow. Specifically, as an embodiment, 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. 5 1 (Fig. 5), the insertion part of the rod 54 (Fig. 8) is the rod 56 (Fig. 10), and the insertion part of the rod 57 (Fig. I1) is the rod. Transform into body 3 (Fig. 3). Insert part above Is connected to the rod-shaped body by integral molding or by separate bonding. As a result, the contact area of the joint portion 21 with the inner peripheral portion can be increased, and a strong adhesive state can be obtained.

Fig. 12 is a front view in which a part of the rod-shaped body 57 of Fig. 11 is omitted, and shows an example in which the rib of the rod-shaped body 3 or the rod-shaped body 57 has a taper (Fig. ). That is, the taper is formed such that the rod-shaped body 58 becomes thinner toward a set of ribs that are axisymmetric. Such a taper formed on 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 the draft angle of the mold when forming the bar body is formed. Therefore, molding becomes easier. The taper may be formed with all of the ribs extending from the shaft-for example, with four. Industrial applicability

In the present application, a rod-shaped body is extended from the mouth into the food container in place of the conventional mouth that extends from the mouth into the food container. As a result, the cooling time has been shortened, from 1 minute per shot to less than 30 seconds.

As described above, 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 stick prevents the inner surfaces of the container body from sticking to each other against the shrinkage deformation of the container body. A suction channel can be formed between the outer surface of the rod and the inner surface of the container body. For this reason, the food is stored in this Can be drawn out from the suction port after passing through the suction channel.

The rod-shaped body consists of a shaft and a group of ribs extending radially from the shaft or axis, and the inner surface of the container comes into contact with the edge of an adjacent rib to form a suction flow path between both ribs Therefore, when the food filled in the container is sucked through the suction port, the inner surface of the container is prevented from sticking around the axis of the rod-shaped body, thereby preventing the container body from contracting and deforming. A suction channel can be formed between the outer surface of the rod-shaped body and the inner surface of the container, that is, between the inner surface of the container and the two ribs that are in close contact with both ends of the adjacent ribs. If the rib is provided with at least one branch rib that branches off from its edges and / or sides, the shape of the container or the inside of the container can be cooperated with the container body. It is possible to form an intentional suction channel according to the remaining amount of food.

The rod-shaped body is fixed at one end with the suction port as a base. When forming a holding means for holding the shape of the suction port when gripping the container, when the container body is gripped. The rod extending from the suction port into the container became the core of the container and assisted in keeping the shape of the container.At this time, the rod fixed in the palm through the container was fixed to the tip end. The posture of the suction port can be guided in the suction direction. If the stick has a base formed with an opening large enough to allow the food enclosed in the container to flow into the suction port when the container is tilted, the remaining food in the container will be sucked when the container is tilted. Can be delivered to the mouth.

With the invention of the present application, it is easy to remove various fluid foods and it remains It is possible to provide a food container that can be taken out of the container without leaving the food to be formed and has high molding efficiency.

Here, as shown in FIGS. 1 to 4, a juice body and a jelly-like food (200 g each) are filled in a container body 1 in which a rod 3 is connected below a mouth 22, respectively. Each of the 10 specimens was prepared, and 10 adults tasted each specimen. The result was that all 10 people were able to aspirate beverages and foods in the container body 1 with little to be left. In addition, the food suction channel was not blocked during suction. The rod 3 had a length of 80 mm, a diameter of 10 mm, an average thickness of the rib 31 of 2 mm, and a radial width of the rib 31 of 4 mm.
