DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION Field of the Invention The present invention relates to an improvement of a cap fitted around a paper carton mainly called a so-called gable top container used as a container for milk, fruit juice, sake and the like. About.

Conventional technology As a cap for a gable-top container,
Although what is shown in 6506 publication has already been proposed,
In addition to the problem that the middle bottom plate separate from the box body must be glued to the box body by means of gluing, binding, tape pasting, etc., in addition to the problem of increased cost due to an increase in the number of manufacturing processes, the gable-top containers are stacked. Sometimes, it is difficult to stabilize the posture because the top surface of the box body is a continuation of the sine curve shape,
Not only may there be a risk of falling due to slight lateral movement, but also when a large number of gable top containers are fully aligned and accommodated in the packaging case, the lid box shown in the above publication is fitted, There is a problem that it is extremely difficult to pull it upward from inside the first single packaging case.

Problems to be Solved by the Invention In view of the above-mentioned problems of the conventional gable-top container lid box, the present invention relates to a small part for holding accessories such as small prizes and foods stored in the cap. It is possible to integrally mold with the cap, without increasing the number of manufacturing processes, and the degree of stability of the posture when stacking the gable top containers with the cap fitted outside is high, and the cap is fitted outside. A gable-top container cap that allows the first single gable-top container to be easily pulled out of the packaging case together with the cap even when a number of gable-top containers are fully aligned in the packaging case. The challenge is to do.

Means for Solving the Problems In order to solve the above problems, the present invention relates to a base tube portion of a cap fitted around the upper end of a container main body of a gable top container, a peripheral wall portion, and a top wall portion. The top wall portion is formed with two concave grooves parallel to each other at intervals, and a single convex portion is formed at the center of the top wall portion.
The upper surface of the top wall portion excluding the groove is a flat surface, and the upper portion of a pair of the peripheral wall portions, which are parallel to the ridge portion, is provided with a finger-recessed recess reaching the upper surface of the top wall portion. A portion is formed, and at least one lower end edge of the base cylinder portion lower end edge parallel to the protruding ridge portion is integrally provided with a folded piece, and the folded piece is folded inward. In this case, the free edge has an extension length in contact with the inner surface of the ridge portion, and a plurality of protrusions projecting inward are formed on the cylinder wall of the base cylinder portion. The configuration is adopted.

In the present invention, since the folded piece is integrally provided at the lower end edge of the base cylinder portion, the molded piece can be integrally formed as a shape extended to the outside of the base cylinder portion at the time of molding with a synthetic resin. After the mold, a large number of caps can be stacked with the same shape.

When storing prizes, put the prizes into the cap with the cap open upward, turn the folded piece back, and make its free end abut the inner surface of the convex part of the top wall, Is restoring elasticity and abuts on the inner surface of the ridge, so that the prizes do not fall off even if the cap is erected.

When the base cylinder portion of the cap is externally fitted to the upper end of the container main body of the gable top container, a plurality of projections projecting toward the inner package are formed on the cylinder wall of the base cylinder portion. Can be fitted with strong pressure.

Of the peripheral wall portions of the cap, a pair of peripheral wall portions parallel to the ridges formed on the top wall portion are formed with finger-recessed recesses reaching the upper surface of the top wall portion. Can be lifted upwards with the thumb and thumb or middle finger, so even if the gable-top container with the cap fitted inside the packing case is fully aligned and stored, the first one It is easy to take out the cap, and at this time, since the base cylinder portion of the cap and the upper end of the container main body are fitted with high pressure, the cap is less likely to come off from the container main body.

In addition, since the top surface of the top wall portion is a flat surface, the stacking posture when vertically stacking the gable top containers with the caps fitted thereon is stabilized.

Embodiment The drawings show an embodiment, in which the cap 1 is manufactured as an integral molded product by means of vacuum molding of a transparent thermoplastic synthetic resin.

As shown in FIG. 5, the cap 1 fitted around the upper end 3 of the container main body of the gable-top container 2 includes a base tube portion 4, peripheral wall portions 5, 6, 7, 8 and a top wall portion 9. Are molded as an integral molded product of the synthetic resin.

The top wall 9 has two parallel grooves 10 and 1 spaced apart from each other.

The upper surfaces 13, 14, 15 of the top wall 9 are flat planes located on the same plane.

Out of the peripheral wall portions 5, 6, 7, and 8, concave portions 16, 17 for finger hooking reaching the upper surface of the top wall portion 9 are provided on upper portions of a pair of peripheral wall portions 6, 8 parallel to the ridge portion 12. Are formed. The concave portion 16 in the peripheral wall portion 6 is communicated with the concave groove 10 by a concave groove 18 formed in the top wall portion 9, and the upper surface 14, 15 is divided by the concave groove 18.

Of the lower edges of the base cylinder 4, one of the lower edges 19, 20 parallel to the ridge 12 has a folded piece 21
Are formed integrally and extend outward.

As shown in FIG. 2, the folded piece 21 has a folded edge 22 inward of the cap 1 as shown by an arrow A and a folded edge 23 in the direction of arrow B located outside thereof. ing.

Although the above-mentioned folded edges 22, 23 are concave grooves having an arc-shaped cross section, they may be folded edges such as perforations.

The above-mentioned folded piece 21 has such an extended length that its free end 24 can abut on the inner surface of the ridge portion 12 of the top wall portion 9 when it is folded inside the cap.

Further, the cylinder walls 25, 26, 27, 28 of the base cylinder portion 4, and in the illustrated example, the cylinder walls 25,
