Description

The present invention relates to a plastic sheet molded food container for containing food such as yogurt.

In a plastic sheet-molded food container for containing food such as yogurt, it is desired to increase the height of the container in order to pursue the appearance at the time of store display.

However, when the height of the container is increased, there is a problem that the liquid level of the content is lowered and the willingness to purchase is reduced.

Therefore, in the prior art, various structures have been proposed in which the cross-sectional area of the container body shape is reduced or the container shape is substantially triangular (Patent Document 1).

Problems that the device tries to solve

However, in the food manufacturing and filling process such as yogurt (that is, yogurt loading), the caliber shape of the jig to which the container is mounted at the time of filling is determined, and if the container shape is changed and the caliber shape of the existing jig is changed, a large remodeling cost is required. Cost.

Moreover, when the cross-sectional area of the container main body is reduced, when printing is performed on the container main body for decoration, the printability is impaired, and it is difficult to take out the contents.

For this reason, the container body is made to be approximately elliptical as a method for efficiently reducing the internal volume while maintaining the printability without losing the printability while using the diameter of the existing jig. It is desirable to do.

However, it is necessary to make the lower part of the flange into a substantially rectangular shape due to the existing jigs, and a step due to the difference in shape occurs at the step that becomes a joint with the container body that is substantially elliptical, and the contents (yogurt) There was a problem that was difficult to scratch.

In order to solve the above problem, it is conceivable to provide a slope at the corner of the step, but as shown in FIG. 5, when the container body is stacked (that is, when the containers overlap), the upper container body is In some cases, the container body enters too much and interferes with a food filling process such as yogurt (that is, yogurt loading).

Therefore, the purpose of the present invention is to adapt to the caliber of the jig in the food manufacturing and filling process such as yogurt, and the contents (yogurt) are easy to scoop out, and it is ensured that the containers enter when the containers are stacked (that is, when the containers overlap). It is to provide a structure that can be suppressed.

Means for solving the problem

The first aspect of the present invention is characterized in that slope portions are formed at four corners of the standing wall portion following the lower portion of the container flange. The slope portion reduces the level difference caused by the difference in shape between the substantially oval container body and the lower portion of the substantially rectangular flange, and easily scrapes the contents (yogurt).

Since the slope portions are formed at the four corners, the standing wall portion through the step portion projecting outward when the container is stacked (that is, when the containers are overlapped) can easily enter, so that the flange portion projects above the standing wall portion. The difference between the opposed inner dimension A and the opposed outer dimension B of the step portion is 1 mm to 4 mm.

As a result, it is possible to reliably prevent the standing wall portions through the stepped portions protruding outward when the containers are stacked (that is, when the containers are overlapped) from each other, and to supply the containers in the food production and filling process (ie, yogurt loading) such as yogurt It becomes possible to reliably supply the container.

The perspective view which shows a mode that the content (yoghurt) is scraped with a spoon from the slope part of a corner in the structure of 1st Embodiment.

Sectional drawing which shows defective embodiment at the time of container stacking (that is, container overlapping)

An embodiment of a plastic sheet-molded food container body according to the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view showing a configuration of a first embodiment of a plastic sheet-molded food container body according to the present invention, and FIG. 2 is a configuration of the first embodiment, and contents (yogurt) are put into a spoon from a slope portion of a corner. FIG. 3 is a perspective view showing a preferred embodiment when the containers are stacked (that is, when the containers overlap), FIG. 4 is a cross-sectional view of FIG. 3, and FIG. 5 is when the containers are stacked (that is, when the containers overlap) FIG.

The plastic sheet-molded food container body shown in FIG. 1 is made of polystyrene (PS), polypropylene (PP), and polyethylene (PE), and the sheet thickness before manufacturing the container is preferably in the range of 1 mm to 2 mm. Then, the sheet manufacturing efficiency is lowered, and the cost is increased due to a large amount of materials. On the other hand, if it is less than 1 mm, the strength of the flange portion and the main body tends to be insufficient.

In the plastic sheet-molded food container shown in FIG. 1, a standing wall portion 2 is provided on the upper end of a container body 5 whose food container body has a substantially elliptical horizontal cross section through a stepped portion 3 projecting outward, A flange portion 1 protruding outward is provided at an upper end of the standing wall portion, and slope portions 4 are formed at four corners of the standing wall portion.

As shown in FIG. 4, the standing wall 2 is preferably provided with a slightly reverse taper.

The thickness of the flange portion 1 is desirably 0.6 mm to 1.5 mm. When the thickness is less than this, when the flange portion 1 and a sealing film such as aluminum are sealed and sealed by heat fusion or the like, the flange portion 1 is properly In some cases, sealing cannot be performed, or the flange portion 1 is greatly deformed during internal expansion and contraction in the manufacturing process of the contents (yogurt) after sealing the lid, and the sealing film may be peeled off.

Further, the thickness of the container body 5 is preferably 0.2 mm to 0.5 mm, and if it is thinner than this, there is a problem that the contents (yogurt) cannot be held due to the impact strength during transportation.

FIG. 2 shows how the contents (yogurt) are scraped off by removing the lid and the seal film. Since there is a slope portion 4, scraping is performed smoothly.

FIG. 3 shows a state when the containers are stacked (that is, when the containers are overlapped). As shown in FIG. 4, the step portion 3 is placed on the lower flange portion 1 so that it does not enter too much. In FIG. 4, the difference between the opposing inner dimension A of the flange portion and the opposing outer dimension B of the stepped portion is suitably 1 mm to 4 mm.
