Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a food packaging container with a squeezing opening, and more specifically, it is a food packaging container with a squeezing spout, and more specifically, it is a food packaging container that allows stored foods such as ice cream to be squeezed out and served directly for consumption. The invention relates to food packaging containers.

[Prior Art] Conventionally, food packaging containers with a squeeze spout generally use a container body that is integrally formed by injection molding of synthetic resin. Specifically, packaging containers for mayonnaise, ketchup, and the like are commonly made of a container body integrally formed by injection molding and a screw lid that is screwed onto the container body.

Furthermore, as a food packaging container with a squeezing opening that allows the stored food to be squeezed out and eaten directly, a container body that is also integrally formed by injection molding and filled with jelly has been proposed. .

``Problems to be solved by the invention'' However, although this type of injection molded container is suitable for mass production and can be manufactured at low cost, it is difficult to print designs etc. on the outside, and it is difficult to store it outdoors. In order to make the container suitable for use in which the food is squeezed out and served directly for consumption, the injection molded container body must be covered with a separate packaging material.
This has the disadvantage that it ends up being an expensive packaging material.

In order to solve the above drawbacks, the container body can be formed by laminating sheet materials that can be freely and easily made into designs such as pattern printing, but such laminated containers do not allow the food to be squeezed out. In such cases, it is difficult to implement as it is inevitable that damage will occur in areas where internal pressure is concentrated.

Therefore, this invention was made in view of the above,
The object of the present invention is to provide a food packaging container with a squeezing spout whose main body can be formed using a sheet material and which has sufficient durability against large internal pressure.

"Means for Solving the Problems" In line with the above-mentioned object, the structure of the present invention having the gist of the above-mentioned claims is surrounded by oblique sides 11a, 11b and an arcuate upper side 11c in order to solve the above-mentioned problems. A container main body forming sheet 10 having a shape in which a substantially rectangular adhesive portion 12 whose lower end protrudes below the apex 11d of the conical developing surface portion 11 is connected to one oblique side 11a of the conical expanding surface portion 11 is waterproofed on the back side. layer 10a
is formed of laminated sheets 10', and one oblique side 11a of this container body constituent sheet 10 is connected to the other oblique side 1.
1b to form an inverted conical shape, the lower end of the adhesive portion 12 is wrapped around the conical apex component, and then the adhesive portion 12 is fixed to the overlapping surface portion of the container body forming sheet 10 to form the container body B. Into the opening B1 of the container body B, a squeeze spout body A having a squeeze spout hole 21 at the center and a flange portion 22 rising diagonally outward on the periphery is fitted. Opening B of main body B
1 is folded back toward the inner surface of the flange 22 at the fold line 11e and fixed to the inner surface of the flange 22, and furthermore, a sheet lid 23 is provided on the upper surface of the diaphragm body A to close the diaphragm hole 21. This is a technical measure that allows the label to be affixed.

``Function'' Therefore, the food packaging container with a squeeze spout of the present invention has the following features:
If a seal lid 23 is attached after a food M such as ice cream is stored in the container body B, the food M can be hermetically packaged.

When a consumer wants to eat this food M, he or she first peels off the seal lid 23. Then, when the container body B is grasped with the spout body A facing upward, the food M is squeezed out from the squeeze spout hole 21 of the squeeze spout body A. You can eat it without touching it.

Note that when the container body B is strongly gripped, the internal pressure of the container body B increases, and a force is applied to the container body B to push it open. This force becomes larger at the bottom of the container body B, which has a smaller cross-sectional area, so the bottom surface of the container body B is the most likely to be damaged. It is reinforced to prevent damage.
In addition, the container body B has an inverted conical shape with a larger diameter at the top, and the squeeze opening hole 21 is located in this larger diameter portion, so that when the container body B is grasped, the stored food M
receives a force in the direction of sliding up the slope of the container body B, and the force toward the bottom of the container body B is attenuated, allowing the food M to be squeezed out without fear of damaging the container body B. .

``Example'' Next, an example of the present invention will be described below with reference to FIGS. 1 to 7.

In the figure, B is the container body. This container body B has a substantially rectangular glue portion whose lower end protrudes below the apex 11d of the conical developing surface portion 11 on one oblique side 11a of the conical developing surface portion 11 surrounded by hypotenuses 11a, 11b and an arcuate upper side 11c. A container body forming sheet 10 having a shape in which 12 are arranged in a row is formed from paper 10' with a waterproof layer 10a laminated on the back side, and one oblique side 11a of this container main body forming sheet 10 is connected to the other oblique side 11b.
The lower end of the adhesive portion 12 is wrapped around the apex portion of the cone, and then the adhesive portion 12 is
is fixed to the overlapping surface portion of the container body forming sheet 10.

In this embodiment, the paper 10' is made by laminating a waterproof layer 10a made of polyethylene or the like on the surface of a paper sheet 10b with an aluminum foil 10c on the surface thereof (or by laminating sheet-like materials), as shown in FIG. Although a synthetic resin material (which may be directly laminated) is used, other conventionally known laminated sheets may be used as long as the waterproof layer 10a is laminated on the back surface. As shown in FIG. 2, this waterproof layer 10a has a lower end protruding downward from the apex 11d of the conical expanded surface portion 11 on one oblique side 11a of the conical expanded surface portion 11 surrounded by oblique sides 11a, 11b and an arcuate upper side 11c. It is cut or die-cut into a shape in which approximately rectangular glue allowance portions 12 are continuously provided. In addition, this glue portion 1
2 is desirably formed to have a width larger than that of a normal adhesive so that its lower end can be sufficiently wrapped around the conical apex of the container body B, as will be described later. This container body configuration sheet 10 is
One oblique side 11a is joined to the other oblique side 11b to form an inverted conical shape. Then, as shown in Figure 3,
The glue margin 12 overlaps the edge along the other oblique side 11b, but the lower end of the glue margin 12 protrudes below the inverted cone. So this glue section 1
The lower end of the container body B is wound around the apex portion of the cone as shown in FIG. 5 after passing through the state shown in FIG. In order to fix this adhesive portion 12, in this embodiment, a thermoplastic synthetic resin is used for the waterproof layer 10a, and the waterproof layer 10a is bonded under heat, but a hot melt type adhesive material may be used. 10d (see FIG. 7) or the like may be used to secure it.

In the opening B1 of the container body B, a squeeze spout body A is fitted, which has a squeeze spout hole 21 in the center and a flange portion 22 that rises diagonally outward at the periphery. This squeeze spout body A is formed by molding a synthetic resin material, and when the squeeze spout hole 21 projects upward from the flange 22, it is easy to eat the food M. Therefore, in this embodiment, the cup portion 2 has a trapezoidal cross section that gradually widens in the hem direction.
The squeeze opening hole 21 is arranged in the center of the upper surface of 0a,
A horizontal flange 20b is provided at the lower end of the hem of this cup 20a.
are arranged in series with a predetermined width, and furthermore, this horizontal flange 20b
The flange portion 22 is connected to the outer peripheral portion of the flange portion.

The edge of the opening B1 of the container body B is folded back toward the inner surface of the flange 22 at the fold line 11e and fixed to the inner surface of the flange 22. The edge folded back at the fold line 11e is the glue margin 12 mentioned above.
Similarly, it can be welded by heat pressure welding or glued with a glue material.

Further, a throttle hole 2 is provided on the upper surface of the throttle body A.
A seal lid 23 is attached to cover the cover 1. Although not clearly shown in the figure, this seal lid 23 is made by laminating a waterproof layer 10a on the back surface similarly to the container body constituent sheet 10, and when pasted, the peripheral edge is welded by heat pressure welding or glued with glue. wear. If the sealing lid 23 is provided with a protruding knob tongue portion 23a as shown by the chain line in FIG.
can be easily peeled off. In addition, although this seal lid 23 is normally attached at the final stage of packaging after the food M is filled and stored in the container body B, the seal lid 23 is attached to the aperture body A in advance, and this aperture The body A may be fitted into and fixed to the container body B filled with the food M. If this is done, even if the squeeze opening hole 21 is small, the food M
A large-diameter nozzle can be used for automatic filling.
A certain amount of food M is injected and filled into the container body B which does not have a thick injection nozzle, and then, after attaching the squeeze spout body A, the food M ( This may be a different food than the one injected last time).
Finally, attaching the seal lid 23 was the most efficient way to fill the food M using an automatic filling machine.

In this example, ice cream was stored in the container body B as the food M. This ice cream does not freeze very hard even under extremely low temperatures, and when it is squeezed out through the star-shaped squeeze opening 21 shown in FIG. It has enough hardness to self-retain. In addition, the food packaging container of the present invention is suitable for packaging soft frozen desserts, pasted foods such as cheese, pasted sweets such as yokan, and the like.

"Effects of the Invention" The food packaging container with a squeeze spout of the present invention as described above uses the container body constituent sheet 10 for the container body B, so the container body constituent sheet 10 itself can be selected from among many types of materials. can,
Design expressions can be freely and easily made on the outer surface by printing means, etc., and a food packaging container with a spout with good appearance can be provided at a low cost.

In addition, the food packaging container with a squeeze spout of the present invention includes:
Since the container body B is shaped like an inverted cone, it is easy to hold with one hand, and since the squeeze spout body A is provided on the large diameter side, the diameter of the squeeze spout hole 21 can be made to a desired size. Alternatively, when the container body B is grasped, the food M slides up the slope of the container body B, so that the food M can be squeezed out with a small force.

Furthermore, in the food packaging container with a squeeze spout of the present invention, since the lower end of the adhesive portion 12 is wrapped around the apex portion of the cone and is fixed to the overlapping surface portion of the sheet 10 constituting the container body, the container body can be removed without removing the seal lid 23. B
It is possible to provide a food packaging container with a squeezing spout that is resistant to damage and has excellent durability even when internal pressure is concentrated at the conical apex at the bottom of the container body B when a force such as strongly crushing is applied. .
