Problems to be solved by the invention

[0005] Certainly, the above-mentioned extruded container is a sanitary and has the advantage of reducing the trouble of cleaning and sterilizing the inside of a refrigerator or the like. Even after the outer film 4 and the outer film 4 are welded, there is still a possibility that bacteria or the like may be mixed in the step of attaching the extrusion hole 8 with the stopper film 9 or the like, and it is not easy to completely prevent the mixing of the bacteria or the like. Was.

[0006] The present invention has been made in view of the above problems, and in an extrudable container made of a substance having fluidity such as ice cream, the step of attaching a plug film to an extruding hole is eliminated to prevent contamination of bacteria and the like. The task is to prevent it as much as possible and to make it sanitary.

Means for solving the problem

[0007] In order to solve the above-mentioned problems, the invention according to claim 1 comprises a sealing member in which a semi-solid or a substance having fluidity is sealed, and the sealing member has flexible side and top surfaces. An extruding container for extruding the substance to the outside by compressing the sealed body with an extruder, wherein the hollow nozzle body with a closed end is provided on the bottom surface of the sealed body. An extruded hole is formed so as to protrude integrally with the bottom surface and extrude the substance when the nozzle body is cut.

[0008] The invention according to claim 2 comprises a sealed body in which a semi-solid or fluid substance is sealed, and a container main body that houses the sealed body, and the sealed body has a flexible side surface. And a top surface, wherein the closed body is extruded by extruding the substance by compressing the closed body with an extruder, and a hollow nozzle body having a closed end at the bottom of the sealed body is provided. A nozzle cover for covering the nozzle body is protruded integrally with the bottom surface of the container body, and the nozzle cover is formed integrally with the bottom surface of the container body. When the nozzle body is cut, an extrusion hole for extruding the substance is formed.

The invention's effect

[0009] According to the invention of claim 1, the sealed body completely seals the substance to be sealed and simultaneously completes the sealing. Since it is completely sealed, the chance of contamination by bacteria and the like in the sealed body is further reduced, so that it is conservative. In addition, the nozzle body protruding from the bottom surface of the sealing body can reinforce it to the extent that it will not bend without the need to make the bottom surface particularly thick. The used container body becomes unnecessary. For this reason, the number of plastic parts is reduced, plastic waste can be reduced, and production costs can be reduced. In addition, since the container body is not required, the step of bonding the inner film to the conventional container body is not required, and the nozzle body whose tip is closed at the time of forming the sealed body is also formed at the same time. The step of closing the extrusion hole with a plug film is not required, thereby significantly reducing the production time and further reducing the production cost.

[0010] According to the invention of claim 2, the sealed body is completely sealed at the same time as the substance to be sealed is sealed, so that the chance of bacteria and the like being mixed in the sealed body is further reduced, thereby contributing to sanitation. It is. In addition, since the sealed body is housed in the container body, the strength of the whole container is increased, and the risk of breakage or deformation when enclosing or transporting the substance to be sealed is reduced, making it easier to handle .

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a longitudinal sectional view of an extrusion-type container according to a first embodiment of the present invention. FIG. 2 is a cross-sectional view of the push-out container cut along a cutting line 26 in FIG. FIG. 3 is a perspective view of the extruded container.

[0013] As shown in Fig. 1, this extrudable container is composed of a thin plastic film seal 10 filled with ice cream A. The sealing body 10 has a bottom surface 12 having no flexibility and a side surface 14 having flexibility, and has a container-like portion 18 having an opening 16 above, and a lid portion closing the opening 16 of the container-like portion 18. It consists of 20 upper surfaces. A flange 22 for welding the lid 20 is provided on the periphery of the opening 16 of the container 18. The side surface 14 and the lid portion 20 of the sealing body 10 have such flexibility that the ice cream A is easily folded and deformed when the ice cream A is extruded from the inside of the sealing body 10, and at the same time, it does not break at this time. The thickness with the strength is selected. As a plastic film material, its strength and strength in a wide temperature range, especially at low temperatures An appropriate material such as polypropylene (PP), linear low-density polyethylene (LLDPE), polyethylene terephthalate (PET), and polystyrene (PS) is selected from the viewpoint of compatibility with flexibility. This material may be made by blending rubber with several suitable plastic materials. The thickness of the plastic film depends on the material or the size, but is usually about 0.1 to 0.6 mm.

On the bottom surface 12 of the container 18, a nozzle body 24 that is not flexible and protrudes integrally with the bottom surface. The nozzle body 24 has a hollow cylindrical shape with a star-shaped cross section (see Fig. 2) and has a tapered shape, and its tip is closed by a flat bottom 24a integrally formed with the nozzle body 24. The bottom surface 12 of the sealing body 10 is reinforced by the nozzle body 24 having a star-shaped cross-section, and is strengthened by the thickness increase due to the roundness of the corner between the bottom surface 12 and the nozzle body 24. The thickness is selected to be about 0.1 -0.6 mm if it does not bend or break when extruded from the sealing body 10. The cross-sectional shape of the nozzle body 24 may be an appropriate shape such as a circle, a triangle, and a square, in addition to the star shape.

When extruding the ice cream A with the push-out container force, the nozzle body 24 is cut along the cut surface 26 to form the extrusion hole 27. In order to cut the cutting surface 26, the nozzle body 24 may be cut with scissors or a knife, but in this embodiment, for safety, the nozzle body 24 is cut so as not to use scissors or a blade. A notch 28 is provided on the entire circumference of the body 24 along the cutting surface 26 so that the nozzle body 24 can be easily cut by pressing with a finger.

[0016] The position of the cut surface 26 may be an arbitrary position up to the vicinity of the root of the nozzle body 24, and the vicinity thereof. The reason for this is that if the cut surface 26 is located near the root of the nozzle body 24, the nozzle body 24 can be easily cut by the force of a finger, but the effect of reinforcing the bottom surface 12 by the nozzle body 24 is lost, and the ice cream A This is because there is a possibility that the bottom surface 12 may be broken during extrusion. In addition, when the cut surface 26 is near the tip of the nozzle body 24, there is also a force that makes it difficult to cut the nozzle body 24 with the force of a finger.

As shown in FIG. 3 (a), the shape of the extrusion type container may be an appropriate shape such as an inverted truncated cone like an ordinary ice cream container, but FIG. 3 (b) or (c). ), The plane shape may be a square or a triangular truncated pyramid. With such a truncated pyramid shape, they can be arranged without any gaps, making transportation and storage convenient. Moreover, if the shape is such a truncated pyramid, In the case of a volume, the side area increases compared to a truncated cone, and heat is easily transmitted to the ice cream A. When the ice cream A is removed from the refrigerator, it melts quickly and has fluidity, so that the ice Cream A can be extruded from seal 10.

[0018] Of course, the shape of the extruded container is not limited to the one shown in FIG. 3, and an appropriate shape such as an elongated shape or a flat bag shape can be selected. If the shape is elongated or flat, the ice cream A that has been frozen can be bent or twisted and crushed, so that the ice cream A can be pushed out of the sealing body 10 in a shorter time.

In the production of this extruded container, the nozzle body 24 can be formed at the same time in the step of molding the container-like portion 18. After this step, the ice-cream A is filled in the container-like portion 18, After the step of welding the periphery of the lid portion 20 to the flange portion 22 of the shaped portion 20 is completed, it can be shipped immediately from the factory. To extrude the ice cream A from the extrusion type container, press the nozzle body 24 with a finger to cut it, and then insert the same extrudable container as the conventional one shown in FIG. 6 into the container holder B of the extruder D. Set it and compress the sealed body 10 with plunger C.

According to the present embodiment, the step of bonding the inner film 3 to the inside of the container body 2 necessary for manufacturing the conventional extrusion-type container as shown in FIG. This eliminates the need for a step of closing, which reduces manufacturing time and cost, and provides an inexpensive extrusion container. In addition, since the step of closing the extrusion hole 8 with the plug film 9 as in the related art is eliminated, the opportunity for bacteria or the like to be mixed into the ice cream A is further reduced, which is sanitary. Furthermore, unlike the conventional case, the container body 2 for reinforcing the sealing body 10 is not required, so that the number of plastic parts is reduced, plastic waste is not generated as much as possible, and a more inexpensive extruded container can be obtained. Further, the thickness of the bottom surface 12 due to the radially extending portion of the nozzle body 24 having a star-shaped cross-section and the thickness of the bottom surface 12 due to the roundness of the corner between the bottom surface 12 of the sealing body 10 and the nozzle body 24 are increased by the entire bottom surface 12. In particular, since the bottom 12 is reinforced near the extrusion hole 27, even when the bottom 12 is thinned, when the ice cream A is pushed out of the sealing body 10, the bottom 12 can be prevented from bending or breaking. Thereby, the generation of plastic waste can be further reduced.

FIG. 4 shows an extrusion-type container according to a second embodiment of the present invention. The extrusion-type container of this embodiment also comprises a plastic film seal 10 filled with ice cream A, as in the first embodiment. However, the nozzle body 24 has a cone shape with a sharp tip, and a flat bottom at the tip. The tip to be provided is closed. Of course, the tip of the nozzle body 24 is strictly rounded to such a degree that it is safe to touch it by mistake. Other than this, the present embodiment is the same as the first embodiment. Therefore, in FIG. 4, the same parts as those in the first embodiment shown in FIG. 1 are denoted by the same reference numerals, and further description is omitted. The extruded container according to the present embodiment can reduce the amount of plastic used for the nozzle body 24 and further reduce plastic waste as compared with the case of the first embodiment.

FIG. 7 shows an extrusion-type container according to a third embodiment of the present invention. The extruded container of the present embodiment has a sealed body 10 formed of a container-shaped portion 18 and a lid portion 20 that closes an opening 16 of the container-shaped portion 18, and has a nozzle body on a bottom surface 12 of the container-shaped portion 18. The point where 24 is formed is the same as the embodiment shown in FIG.

However, in the present embodiment, the sealing body 10 is housed in a non-flexible container body 30 like the conventional extrusion-type container shown in FIG. The side surface 14 and the flange portion 22 are adhered to the bottom surface 32, the side surface 35, and the flange portion 36 of the container body 30. The bottom surface 32 of the container body 30 is also provided with a nozzle cover 34 for covering the nozzle body 24 provided on the bottom surface 12 of the container 18. PET-G is suitable for the material of the container body 30. Other than this, the present embodiment is the same as the first embodiment, and further description will be omitted.

When extruding the ice cream A from the extrudable container, the nozzle cover 34 and the nozzle body 24 are cut along the cut surface 26 to form an extrusion hole 27. To cut the cut surface 26, the nozzle cover 34 and the nozzle body 24 are cut with scissors or a knife. In this embodiment, a notch 38 is provided along the cut surface 26 on the entire circumference of the nozzle cover 34 in order to facilitate cutting with scissors or a blade. Of course, a notch may also be provided in the nozzle body 24 in accordance with the notch 38 in the nozzle cover 34 so that the nozzle cover 34 and the nozzle body 24 can be easily cut by pressing with a finger.

[0025] According to the present embodiment, the step of closing the extrusion hole 8 with the plug film 9 as in the related art is eliminated, so that the chance of bacteria and the like being mixed into the ice cream A is further reduced, and sanitation is achieved. Further, since the sealing body 10 is accommodated in the container body 30, the strength of the entire extrudable container is increased, and the extrudable container is damaged or deformed when the ice cream A is sealed or transported. Less fear and easier handling.

By the way, the present invention is not limited to the above embodiments, and various modifications are possible. For example, the substance sealed in the sealed body 10 is not limited to ice cream and other frozen desserts, but may be a semi-solid or fluid food or the like which must prevent the contamination of bacteria and the like. Further, in the third embodiment shown in FIG. 7, the nozzle bodies 24 and 34 are not provided with flat bottoms, and as in the embodiment shown in FIG. Form it into 34.
