Description

[Detailed description of the invention] This invention relates to an insulated bottomed container for storing frozen confectionery, and more specifically, to an insulated cup-shaped container that allows attachment of a foam insulation member and an outer cylinder label to the outer periphery of the container. It is something.

Cone-shaped containers and cup-shaped containers for ice cream are generally made of waterproof paper, and in this case, when they are in the form of paper sheets, they can be pre-sealed and the outer surface can be printed.

However, such paper containers require high raw material costs and require many processing steps, making them expensive. Therefore, thinner containers made of synthetic resin such as polyethylene, which have lower material costs and are easier to process than processed paper, are used. container is used.

However, even with curved surface printing technology, it is impossible or difficult to print multicolors on the front side of such thin-walled cup-shaped containers made of synthetic resin, so it is difficult to print multiple colors on the front side. It is often processed into a conical shape and attached to the outside of the container.

In this case, if the purchaser inadvertently tilts his or her hand a little when they are mated, the side of the container containing the contents will fall out, so it is necessary to attach the outer sleeve paper to the container. In addition to the disadvantage of poor workability, it also had the disadvantage of not having a heat insulating effect.

The purpose of this invention is to eliminate the above-mentioned drawbacks.The main feature of this invention is that a foamed heat insulating member is placed outside the outer diameter of the thin-walled bottomed synthetic resin container near the bottom of the container. A protrusion is provided to prevent the label from slipping off, and the protrusion locks the heat insulating member and the outer cylinder label. To provide a bottomed container made of synthetic resin for holding frozen confectionery which prevents the container from coming out.

An embodiment of this invention shown in the drawings will be described in detail below.

As shown in Fig. 1a, the bottomed container of this invention is made of a thin cone-shaped container body 1 with a castable synthetic resin such as polyethylene placed slightly outside the bottom 2 of the container body 1 on the opening 3 side. A plurality of protrusions 4 for preventing slipping of the outer cylinder paper, which protrude outward from the main body and are inclined toward the opening side, are formed at the same time when the main body is cast.

Figure 1 shows a foamed heat insulating member A to be fitted on the outside of the bottomed container described above, which has a truncated conical shape, with an upper end a1 close to the outer edge rib 5 of the container 1 and a lower end a2 to prevent the outer cylinder label from slipping off. The outer cylinder label is attached to the outside of the foam heat insulating member as described below.

FIG. 1C shows an outer cylinder (label) 6 to be attached to a container having the above-mentioned protrusions 4a or ridges 4b formed on the outside, and an edge 7a of a fan-shaped thin sheet of paper (or synthetic resin film).
, 7b are laminated with a suitable adhesive and processed into a truncated conical shape, and the product name and the like are printed in multiple colors on the surface before the processing.

As shown in FIG. 2, this outer cylindrical body 6 and the foamed heat insulating member A have an outer diameter dimension from the bulge of the outer edge rib 5 formed at the opening of the container body 1 to the bulge of the protrusion 4. Since they are approximately the same size, they are fitted from the bottom 2 side of the container body 1.

In this case, the protrusion 4 is formed thinner than the container body 1,
Furthermore, due to the elasticity of the materials of the container body, outer cylinder 6, and foam insulation member A, they easily pass through the protrusion 4a, and when the large diameter end 8 and al reach the vicinity of the outer edge rib 5, the small diameter end 9
and a2 pass over the protrusion and are locked to this protrusion.

Fig. 3 shows a modification of this invention, in which the protrusion 4a is forcibly expanded outward by extrusion after forming the bottomed container body by casting. This figure shows a case in which continuous annular protrusions 4b are bulged along the entire circumference by extrusion processing at the same time as casting or after casting.

Note that instead of fitting the outer cylinder 6 to the container body 1 via the foamed heat insulating member A after pasting its edges 7 a and 7 b as described above, the outer cylinder 6 is attached to the protrusion 4 of the container body 1 and the outer edge rib 5 . Alternatively, the edges 7 a and 7 b may be bonded simultaneously with the winding.

Moreover, what is shown in FIG. 5 is a cross-sectional view of a modified example, and shows an example implemented in a container shallower than the bottomed container described above, and parts with the same symbols as those in the example described above indicate similar members. be.

As mentioned above, this invention provides a protrusion near the bottom of a thin-walled synthetic resin container with a bottom outside the outer circumference of the portion to prevent the foamed heat insulating member and outer cylinder label from slipping off. A thin paper label for external decoration can be easily attached to the outside of the container, and it will not slip off.The label has beautiful multicolor printing, and has good insulation properties to keep the contents of the container warm and cool. It has the effect of not causing burns.
