Description

[Detailed description of the invention] Γ Industrial application field This invention is an invention related to a double-sealed container, which is an improved container that can be used to hold soft drinks such as youth and carbonated drinks, and alcoholic beverages such as alcoholic beverages. This relates to double-closed containers.

Γ Prior Art In the prior art, composite cans, synthetic resin containers, and aluminum cans are known as simple beverage containers. The conventional container is used as a container by tightly wrapping metal lids around the upper and lower openings, respectively. When opening the container, etc., a drinking spout is made in a part of the top opening using an opening tool attached to the metal lid, or the entire top lid is peeled off and the drinking spout is opened for drinking. ing.

Γ Problems to be Solved by the Present Invention Among the conventional techniques, the present invention is characterized by the fact that when the lid is tightly wrapped around the top opening of the container, the entire lid is peeled off and opened as a drinking spout. The sharp opening edge of the lid remains around the side wall of the container, and this opening edge often injures fingertips and the like when opening the container.

The present invention was made to prevent and eliminate injuries to fingertips, etc., which could not be solved using conventional techniques.

Γ Means for Solving the Problem The present invention consists of a paper container 10, a thermoplastic synthetic resin container 30, and a metal lid 40.
Insert the inverted truncated cone-shaped synthetic resin container 30 into the paper container 10 and adhere the upper ends 13 and 32 of the side wall 12 of the paper container 10 and the side wall 31 of the synthetic resin container 30 with adhesive 20, Furthermore, in a double sealed container formed by wrapping the flange portion 41 of the lid body 40 around the flange portion 33 of the synthetic resin container 30,
The synthetic resin container 3 is placed directly under the lid body 40.
A rib 36 that extends around the side wall 31 and protrudes in a convex shape is provided on the upper end 32 of the side wall 31 of 0, and the inner diameter r of the rib 36 is configured to be smaller than the inner diameter R of the opening edge 44 of the lid body 40. This invention relates to a double-sealed container, which prevents and solves injuries to fingertips, etc., which could not be solved with previous techniques.

Γ Effect When opening a double-sealed container, when the opening tool is pulled upward, the central part of the lid is torn from the tear groove, peeled off, and opened. A portion remains and remains as a sharp opening edge. Since the edges of the opening are metal and sharp, the drinker's fingertips often come in contact with the drinker's fingertips and get injured when opening the drinker.

In the present invention, the opening edge 44 has an inner diameter R, which is larger than the inner diameter r of the rib 36. In other words, the rib 36 is formed to protrude inwardly from the opening edge 44, and the opening edge 44 extends beyond the rib 3.
It is closer to the side wall 12 of the paper container 10 than 6, and even if the fingertip approaches the opening edge 44 when opening the opening edge 44, it is safe because it will touch the rib 36 first and will not directly touch the sharp opening edge. .

Γ Example The example of the present invention will be explained according to the drawings.1
0 is a paper tip with an almost inverted truncated cone shape, paper tip 1
0 has a bottom paper 14 on a tip main body 11, which is constructed by winding up a fan-shaped paper obtained by punching cardboard into a substantially fan shape.
That is, the bottom paper 14 is inserted into the lower end of the top main body 11 by folding its circumferential edge 15 as shown in FIG. By fixing the paper tips 15, the paper tip 10 is formed.

Vinyl acetate adhesive 20 is applied to the inner surface of the upper end 13 of the paper tip 10 at two or more locations. The adhesive 20 may be wound around the inner surface of the upper end 13 of the paper tip 10 in a band shape.

The container 30 made of polyethylene terephthalate (PET) is formed into a substantially inverted truncated conical shape whose diameter increases from its lower end toward its upper end. A PET container 30 is inserted inside the paper cup 10, and a flange portion 33 is extended from the upper end 32 of the side wall 31. The height of this flange portion 33 is paper tip 1
It is desirable that the height is higher than the height of 0,
Its outer diameter is approximately equal to the inner diameter of the paper tip 10, and the side wall 31 has a large number of thin folds 35. Upper end portion 32 of side wall 31 and flange portion 3
3 and the bottom portion 34 are formed thicker than the thickness of the fold portion 35. The aluminum lid 40 may be made of other metal or synthetic resin with the same effectiveness. This aluminum lid body 40 is PET
A rib 36 that extends around the side wall 31 of the PET container 30 and protrudes inwardly is located directly below the lid 40 at a position inserted into the opening 60 of the container 30.
is formed, and this circumferential rib 36 has an inner diameter r. The shape of the rib 36 may be a convex rib, or may be semicircular, square, chevron-shaped, etc., and any shape can be selected as long as it is not a sharp protrusion. Flange portion 41 of aluminum lid body 40
The peripheral edge portion 42 seams the upper ends 13 and 32 of the PET container 30 and the paper tip 10, respectively, and integrally double seams to form the seamed portion 50. The center portion 43 of the aluminum lid 40 fits into the opening 60 of the paper cup 10. Further, on the outer periphery of the central portion 43 of the aluminum cover 40 that has entered the opening 60 of the paper tip 10, there is a tear groove 45 that extends around the middle of the thickness of the cover 40 and extends around the cover 40. When opening the provided paper tip 10, when the opening tool 46 is lifted upward, the center portion 43 of the lid 45 is torn off from the tear groove 45, and the portion other than the center portion 43 of the lid 40 is sharp. It remains as an opening edge 44.

Since this opening edge 44 is plate-shaped and sharp, it often touches the tip of a drinker's finger when opening the drinker, causing injury.

The opening edge 44 of the present invention has an inner diameter R, which is larger than the inner diameter r of the rib 36. That is, the rib 36 forms a state in which it projects more inward than the opening edge 44, and the opening edge 44 is closer to the side wall 12 of the paper tip 10 than the rib 36 is. Even when the aluminum lid body 40 is opened and the fingertip approaches the vicinity of the opening edge 44, it is safe because the fingertip first touches the rib 36 and does not directly touch the sharp plate-shaped opening edge 44.

To obtain the present invention configured as described above, the PET container 30 is inserted into the paper tip 10, the bottom surface 34 is cut off or brought close to the paper tip 10, and then the PET container 30 is inserted into the paper tip 10. Paper tips 10
After the side walls 12 and 31 of the PET container 30 are filled with liquor 61, etc., the flange portion 41 of the aluminum lid body 40 is attached to the flange portion 33 of the PET container 30. Sealing part 5 by integrally double-sealing the seaming part 5.
0 can be formed to obtain a double sealed container.

Γ Effect In the present invention, a circumferential rib is provided on the side wall of the synthetic resin container directly below the lid, that is, directly below the opening edge formed when the container is opened, and the inner diameter of the rib is larger than the inner diameter of the opening edge. Since it is small, the fingertips etc. come into contact with the ribs without directly coming into contact with the sharp opening edge, thereby preventing injury to the fingertips and providing a safe container. Since this invention is a double-sealed container, the paper container acts as a protective wall for the synthetic resin container containing the beverage, preventing the beverage from immediately spilling out even if the paper container is damaged during transportation or handling. In addition, since the bottom of the synthetic resin container is cut into the paper container, it has an anti-vibration effect against vertical and lateral vibrations.
It also helps protect the beverage inside.
