Description

[Detailed description of the invention] This invention relates to an insulated bottomed container for storing sweets, and more specifically, it is possible to attach a cover paper to the outer periphery of the container, such as an insulated bowl, a cup, a cone type, etc. It concerns containers.

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, the outer surface can be printed in advance for decoration.

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 polystyrene, 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. 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. It had the disadvantage of poor workability.

The purpose of this invention is to eliminate the above-mentioned drawbacks, and its features include forming a large number of protrusions on the outer periphery of a thin-walled synthetic resin container with a bottom, and forming a peripheral portion near the bottom of the container. The present invention provides an insulating bottomed container characterized in that a protrusion for preventing the outer cylinder paper from slipping is provided outside the outer circumferential diameter of the portion.

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

As shown in FIG. 1a, the insulated bottomed container of this invention has a large number of protrusions 1A formed on the outer periphery of a thin cone-shaped container body 1 using a synthetic resin for casting such as polystyrene, and A plurality of protrusions 4 for preventing slipping of the outer cylindrical paper, which protrudes outward from the diameter of the part and slopes toward the opening, are formed at the outside of the bottom part 2 slightly on the side of the opening 3 at the same time when the main body is cast. This is what I did.

FIG. 1 shows an outer cylindrical body (label) 6 to be attached to a container having the above-described protrusion 4 on the outside, and an end edge 7a of a fan-shaped thin paper sheet (or synthetic resin film).

7b is 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 FIGS. 2A and 2S, the outer diameter of the outer cylinder 6 is approximately smaller than the outer diameter 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 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 material of the container body and the outer cylinder body 6, it passes through the protrusion 4a without any problem, and when the large diameter end 8 reaches the vicinity of the outer edge rib 5, the small diameter end 9 passes over the protrusion and is locked to this protrusion. do.

In addition, in this installed state, the outer cylinder body 6 due to the groove g of the container 1
Due to the space between the containers, the container 1 exhibits a heat insulating effect, and can effectively keep the contents warm and cold.

Fig. 3 is an enlarged cross-sectional view of a partially cutout in which a protrusion 1A is provided on the outer periphery of the container, and Figs. In any case where the protrusion 4a is partially bulged outward by extrusion, a continuous annular protrusion 4b is formed along the entire circumference by extrusion at the same time or after the container body is cast. This shows the case where it is bulged.

Note that instead of fitting the outer cylinder 6 into the container body 1 after pasting its edges 7a and 7b together as described above, the outer cylinder 6 is attached to the protrusion 4 of the container body 1.
and the outer edge rib 5, and simultaneously wrap the end edge 7a.
, 7b may also be bonded.

5a to 7 are perspective views and cross-sectional views of modified examples, which are implemented in a container shallower than the above-mentioned heat-insulating bottomed container, and are designated by the same reference numerals as those of the above-mentioned embodiment. Parts indicate similar parts.

A heat-insulating cone container as a modification of this invention is shown in Figure 8a.
As shown in FIG. 9a, a large number of protrusions 11A are formed on the outer periphery of a thin cone-shaped container body 11 using a casting synthetic resin such as polystyrene, and an opening 13 is formed slightly from the tip 12 of the container. A plurality of protrusions 14 for preventing slipping of the outer sleeve paper, which protrude outward from the diameter of the portion and slope toward the opening side, are formed at the same time when the main body is cast.

Figure 8 shows an outer cylinder (label) 16 to be attached to a container with the above-mentioned protrusion 14 formed, and edges 17a and 17b of a fan-shaped thin paper sheet (or synthetic resin film) are pasted with a suitable adhesive. It is processed into a truncated conical shape, and the product name etc. are printed in multiple colors on the surface before the processing.

As shown in FIGS. 9A and 9S, this outer cylinder 16 has an outer diameter dimension from the point where the outer edge rib 15 formed at the opening of the container body 11 bulges to the point where the protrusion 14 bulges out. Since they are the same size, they are fitted from the tip 12 side of the container body 11.

In this case, the protrusion 14 is formed thinner than the container body 11, and due to the elasticity of the materials of the container body and the outer cylinder 16, it easily passes through the protrusion 14, and the large diameter end 18 reaches near the outer edge rib 15. At this time, the small diameter end 19 passes over the protrusion 14 and locks onto this protrusion.

In addition, in this installed state, the outer cylinder 1 due to the groove g of the container 11
The container 11 exhibits a heat insulating effect due to the six spaces, and can effectively keep the contents warm and cold.

FIG. 10 shows another modification of this invention, in which the cone-shaped container body is formed by casting and then the protrusion 14 is forcibly bulged outward by extrusion. A continuous annular protrusion 14 may be bulged out over the entire circumference at the same time as casting or by casting extrusion.

As mentioned above, this invention forms a large number of protrusions on the outer periphery of a thin-walled synthetic resin container with a bottom, and also forms a ridge on the peripheral part near the bottom of the container to prevent the outer cylinder paper from slipping outside the outer diameter of the part. The protrusion makes it easy to attach a thin paper label for external decoration to the outside of a bottomed container, and it will not slip off.The label can be beautifully printed in multiple colors, and it can be attached to the outer tube label and heat insulation. The blank space formed by the groove g of the container keeps the contents of the container well warm and cold, and has the effect of preventing frostbite burns on hands and fingers.
