Description

[Detailed Description of the Invention] The present invention relates to a synthetic resin container for gel-like confectionery such as pudding and water yokan.

In recent years, when manufacturing synthetic resin containers or eaves for storing gel foods such as puddings, ice cream confections, and tofu,
It has become popular to pour the sol-like liquid, which is the raw material for these gel-like foods, into a synthetic resin container, and then gel it into a desired food product, which is then sold together with the container.

As a method of transferring the gel-like food from such a container to a plate without losing its shape, as shown in FIG. After peeling off the food, place the container containing the food on a plate etc.
The rod-shaped projection 21 is pushed down and removed to create an air hole in the projection base 22.

Air is introduced into the container through the bottom air hole in a displacement manner.

Because the gel-like food is in one piece and can be easily transferred onto a plate,
Gel-like foods can now be taken out without damaging their appearance.

However, in the case of the conventional rod-shaped air holder 21, the air hole that opens when the protrusion 21 is collapsed is approximately circular with a small diameter, so the inflow of air cannot necessarily be said to be quick. If there is moisture, the food may not easily come out in an integral shape while keeping its shape depending on its concentration, etc., There is a drawback that it is not easy to remove the short and small rod-like protrusions with fingertips, and there are also disadvantages such as the broken rod-like protrusions scattering and creating dust, or falling into the container.

The present invention eliminates the above-mentioned drawbacks of the prior art, and facilitates opening and manufacturing as described below.

As shown in FIGS. 2 and 3, the synthetic resin container according to the present invention has a thick plate-shaped protrusion 25 extending from the back surface 16 of the bottom 11 of the container 10, and the height h2 of the plate-shaped protrusion 25 is The height is lower than the height hl of the container foot 12, and the flat plate-like protrusion 2
A thin groove 13 is provided on the back surface 16 of the container bottom 11 along the periphery of the base of the container 5.

Furthermore, as shown in FIG. 4, the thick inner portion 28 as a discontinuous portion of the thin wall portion 13 connects the bottom portion 11 and the base of the flat projection 250, and the thick portion 28 is connected to the base of the flat projection 25 at approximately the center of the base of the flat projection 25.
A claw portion 26 with an acute angle at the tip is provided on the opposite surface.

In this way, in the present invention, since the protrusion 25 is made into a flat plate that stands upright with respect to the bottom part 11, the part to which force is applied is a point or a line in the conventional bar-shaped protrusion 21.
Since the protrusion 25 of the present invention has a flat plate shape, it is possible to apply pressure to the flat plate surface, so a strong pressing force can be applied when pushing down the flat protrusion 25 and open the air hole. The force pushes down the protrusion 25 from the claw side to the opposite side, and the claw tip is strongly pulled up.Even if the opening breakage part is wide in the shape of a T, the breaking force is concentrated on the claw tip 21 without being dispersed. This causes initial breakage at the tip 21 of the claw portion, making it easier to break the opening at the base of the protrusion 25.

The height of this protrusion is generally 10% or less in conventional containers for gel-like foods such as pudding, and its diameter is as small as 2 to 3%, so it cannot be pushed down with the tip of the thumb. However, the disadvantage was that I felt strong tenderness in my fingertips.

However, in the present invention, the protrusion is made into a flat plate and force is applied to the surface, so compared to the conventional method of applying force to a rod-shaped protrusion, it is ergonomically effective and can generate a stronger force than expected without feeling any tenderness. Even if the breaking point is wide, the opening can be easily broken without dispersing the pressing force due to the claw portion 26.

Furthermore, as shown in FIG. 4, by providing a discontinuous portion in the thin wall portion 13 of the circular side of the protrusion 25, the flat protrusion 25
The thickness of the bottom 11 (see FIG. 5) is connected to the side surface of the container with the thickness of the bottom 11 (see FIG. 5).
Therefore, in order to break the connection thick part 28, a force greater than that required to break the thin part 13 is required.

Therefore, when the protrusion 25 is pushed down onto the thick connection part 28, only the thin part 13 is usually broken, and the thick connection part 28 is not broken.

Therefore, the flat plate-like protrusions 25 do not separate from the container bottom 11, so they do not scatter and create dust, and there is no risk of them falling into the container, which is sanitary.

In the present invention, since the protrusion 25 is flat, the air hole opened by pushing down the protrusion 25 and breaking the thin part 13 has a linear shape with a required width. Compared to the minute circular holes, the opening area is much wider, allowing a sufficient amount of air to quickly flow into the container and be replaced.

Therefore, by inverting the container 10 and pushing down the protrusion 25, the contents of the gel-like tableware can be extremely easily lowered onto the saucer without being distorted.

Further, the present invention has the same thickness as the container bottom 11 by simply forming the thick wall portion 28 as a discontinuous portion of the thin wall portion 13, that is, forming a discontinuous portion in the thin wall portion 13 surrounding the flat protrusion 25. Since the inner part 28 is molded to a thickness of 28, it is easy to manufacture a container with this structure.

As mentioned above, the present invention has a height h of the foot 12 of the container on the back surface 16 of the bottom 11 at an appropriate position in the axial direction of the container and downward.
A flat plate-like protrusion 25 with a height +2 shorter than l is extended, a thin groove portion 13 is provided so as to surround the base of the protrusion 250, and
A discontinuous portion is provided in the thin portion 13 to form a thick interior 28, and the thick portion 28 connects the base of the flat projection 25 to the bottom portion 11.

Furthermore, a synthetic resin container characterized by a structure in which a claw portion 26 having an acute tip at the base of the flat projection 25 is provided on the opposite side of the thick portion 28 so as to intersect with the flat surface of the projection 25. 10, when opening the air hole, force can be applied to the flat surface to push down the flat plate-like projection 25, so force can be easily applied to the base of the projection 25, and the suppressing force can be dispersed. Instead, the breaking force is concentrated on the claw portion 26, which not only facilitates the opening but also causes the opening pieces to scatter.
The tube has various advantages: it is sanitary without dropping the opening piece into the container, and since the opening is linear, a sufficient opening area can be obtained.

In the above-described embodiment, the plate-shaped protrusion 25 is in the form of →, but the plate-shaped protrusion 25 is not limited to one but may be plural.

For example, in an embodiment in which two protrusions 25 are provided, the two protrusions 25 are made to face each other as shown in FIG. When providing the claw portion 26 to the opening 25, if the claw portion 26 is provided outside the two flat plate-like projections 25, the peripheral projection 25 can be easily opened by pinching the peripheral projection 25 between the thumb and forefinger.

Further, the thin groove portion 13 provided around the flat plate-shaped projection 25 is not limited to the outside of the back surface of the container bottom 11, but the linear groove portion 14 is formed on the inner surface 15 of the bottom portion corresponding to the portion of the protrusion provided on the back surface of the bottom portion 11. By providing this, a thin groove portion 13 having a discontinuous portion may be formed.

Furthermore, the legs 12 of the container are not limited to continuous shapes as shown in Figures 12 and 3, but may also be discontinuous.

In short, it is sufficient that the legs 12 are higher than the plate-like protrusions 25 so that they can protect the plate-like protrusions 25 and stably support the container 10.
