Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plastic bottle composite, and more particularly to a plastic bottle composite including a base cup and a cover cup.

Plastic bottles have recently come to be used as containers for storing food such as beer, carbonated drinks, alcohol, and juice.

If the food to be stored is light-resistant, such as beer, plastics to which colorants such as pigments and dyes are added are usually used as bottle materials.

The use of such colorants is undesirable from the viewpoint of food hygiene or the reuse of bottle raw materials.

The present invention was developed in view of the problems of the conventional technology as described above, and the main purpose of the present invention is to improve hygiene, light-shielding properties,
Another object of the present invention is to provide a plastic bottle composite with excellent reusability of bottle raw materials.

In order to achieve the above object, the present invention is a plastic bottle with a pace cup attached to the bottom of the uncolored plastic bottle, a cover cup attached to the shoulder and lower part of the neck, and a label covered all over the body. A bottle composite, wherein the pace cup, the cover cup, and the label are all made of a light-shielding material, and the lower end of the label covers the outer surface of the upper end of the base cup, and the label The plastic bottle composite is characterized in that the upper end is inside the lower end of the cover cup.

The present invention will be described below with reference to the drawings which are examples.

1 and 2, a plastic bottle composite 1 includes a plastic bottle 2 (hereinafter referred to as bottle), a base cup 3 attached to the bottom 2a of the bottle 2, a shoulder 2b and a neck 2C of the bottle 2. The bottle 2 includes a cover cup 4 attached to the lower part 2C1, a metal cap 5 screwed onto the threaded part 2C2 of the neck 2c, and a label 6 attached to the entire outer surface of the body 2d of the bottle 2. Inside,
For example, a light-resistant content 7 such as beer is stored.

The bottle 2 is, for example, a biaxially stretched and blown polyethylene terephthalate bottle formed from a plastic parison without the addition of a coloring agent, and is colorless and transparent. In order to ensure internal pressure resistance, the bottom 2a is hemispherical and shaped. The shoulder portion 2b is formed into a truncated hemispherical shape.

Since the bottom portion 2a is hemispherical, the bottle 2 itself is not self-supporting.

Therefore, the base cup 3 having the annular peripheral protrusion 3a forming a ground surface is fitted onto the bottom portion 2a, thereby ensuring the stability of the bottle 2 in its upright position.

Note that the annular inner protrusion portion 3b and the bottom portion 2a are joined with an adhesive (not shown).

As clearly shown in FIGS. 3 and 4, a plurality of (four in the figure) vertical grooves 9 are formed at equal intervals in the circumferential direction on the upper outer surface of the bottom portion 2a of the bottle 2.

The vertical groove 9 has the function of ensuring air release at the final stage of fitting the base cup 3 to the bottom portion 2a and realizing reliable fitting (preventing washing water etc. from entering the base cup 3). Therefore, no air vent hole is provided.

). In addition, as shown in FIGS. 7 and 8, instead of providing the vertical groove 9 in the bottom 2'a of the bottle 2, the same result can be obtained by using a base cup 3' having a similar vertical groove 9' in the upper part of the inner surface. It can be effective.

Of course, vertical grooves may be provided on both the upper outer surface of the bottom of the φ' torque and the upper inner surface of the base cup.

A stepped portion 10 is formed at the boundary between the lower end of the body 2d and the upper end of the bottom 2a of the bottle 2 (see FIGS. 3 and 5), and is fitted onto the outer surface 2dt of the lower end of the body 2d. The outer surface 3c of the upper end of the rear base cup forms a common cylindrical surface.

Therefore, defects such as wrinkles or breaks are prevented from occurring in the lower end 6a of the label 6 that is adhered onto the outer surface 3C of the upper end.

The base cup 3 is made of light-shielding plastic (for example, polyethylene) to which pigments, dyes, etc. are added.

The cover cup 4 is also made of light-shielding plastic (for example, polyethylene) to which pigments, dyes, etc. are added.

The cover cup 4 has an annular peripheral protrusion 4a extending to the level of the upper surface of the metal cap 5 and, in cooperation with the base cup 3, gives the plastic bottle composite 1 a beer barrel-like appearance. .

The naori bar cup 4 has an upper end 4 of a central short cylindrical portion 4b.
At b1, the neck ring 8 of the bottle 2 is fitted.

The label 6 may be made of a light-shielding film such as aluminum foil, opaque waterproof paper, colored plastic film, or a laminate thereof, and may be attached to the body 2d, or may be printed on the entire surface or printed on the entire surface. The body portion 2d may be shrink-coated with a metal vapor-deposited or colored heat-shrinkable plastic film.

The label 6 has its lower end 6a as clearly shown in FIG.
extends on the upper outer surface 3c of the base cup 3.

Therefore, during cleaning work or water cooling, the stepped portion 10 of the bolt
Water is prevented from entering the base cup 3 through the gap between the base cup 3 and the upper end 3d of the base cup 3.

The raised portion 3e of the base cup 3 located below the label 6 has the effect of preventing external peeling force from acting on the lower end 6a of the label 6 from below, thereby preventing the label 6 from peeling off.

Further, as clearly shown in FIG. 6, the upper end 6b of the label 6
is located between the body 2d of the bottle and the lower end 4c of the cover cup 4, so that the label 6 is prevented from peeling off from the upper end 6b.

Note that 11 is a printing section in which trademarks, products, etc. are printed on the surface of the label 6.

The present invention is not limited to the above embodiments,
For example, the base cup 3 and cover cup 4 may have other suitable shapes.

Moreover, a light-shielding plastic cap may be used instead of the metal cap 5.

The plastic bottle composite of the present invention is hygienic because the plastic bottle that comes into direct contact with the contents is uncolored, and the bolt raw material is highly reusable, and the entire outside of the bottle is made of a light-blocking material. Since it is covered with the base cup, cover cup, and label, it has a light-blocking property and has the effect that there is no risk of the contents being deteriorated by light.

Furthermore, the lower edge of the label covers the outer surface of the upper edge of the base cup, so water does not enter the base cup during washing or cooling, and the upper edge of the label covers the inside of the lower edge of the cover cup. This has the advantage that the label will not peel off from the top end.
