Definitions
- the present invention relates to an in-mold label type plastic container. Background art
- the in-mold label type container has no step between the label and the container, it can exhibit excellent design properties as a whole container, and can also be used as a plastic container for food and beverages such as coffee, jordart, etc. It is widely used. Disclosure of the invention
- This problem can be solved by eliminating the variation in the dimensions of the in-mold label and fixing it inside the female mold by some means. It is almost impossible to eliminate the error due to the size of the label, and if a means for fixing the label is provided inside the female mold, the mounting of the label itself becomes complicated, which leads to a decrease in yield, which is not preferable.
- the plastic container with the in-mold label method is beautiful (specifically, the entire container can be covered with a label, and there is no step between the label and the resin, gravure, offset, etc.). It has the characteristic that the reproducibility of the design is good because the label can be printed by printing). In particular, it is often used for beverage cups, and general consumers may eat and drink the contents by attaching a direct opening to the opening of the in-mold label plastic container.
- the opening of the plastic container with the in-mold label method is required to have a feeling of mouthfeel and safety.
- the present invention has been made in view of such a situation, and even when the in-mold label has a slight dimensional error, it is manufactured without impairing the designability and without lowering the yield.
- the main problem is to provide an in-mold label type plastic container that can perform the in-mold label type plastic container, and to provide a safe in-mold label type plastic container even when eating and drinking the contents by directly opening the opening of the container.
- the present invention uses a female mold and a male mold as described in claim 1, and forms an inner portion of a gap formed by combining the female mold and the male mold.
- An in-mold label type plastic container manufactured by an in-mold label type manufacturing method in which a mold label is attached, and then the molten resin is injected into the gap to perform labeling simultaneously with molding of the container.
- a flange portion is formed at the upper end of the side wall portion of the container. The dimensions of the flange portion are that the flange width is 2 mm or more and the flange thickness is 0.5 mm or more.
- the flange width of the flange portion is 2 mm or more, the sealing strength at the time of sealing the lid material attached to the opening at the upper part of the container can be made sufficient, and it can be directly applied to the mouth. You won't feel uncomfortable when you touch it. Also, since the flange thickness is 0.5 mm or more, it can withstand the damage to the flange part when attaching the lid material.
- the present invention uses a female mold and a male mold as described in claim 2, and the inside of a gap formed by combining the female mold and the male mold.
- An in-mold label-type plastic container manufactured by an in-mold label-type manufacturing method in which an in-mold label is attached to the container, and then, the molten resin is injected into the gap to perform labeling simultaneously with molding of the container.
- a thread portion is formed below the container, and has a dimension of 0.3 mm or more and 20 mm or less. The same labeling as that of the container side portion is applied to the thread portion.
- the present invention provides an in-mold label type plastic container characterized in that: -According to the present invention, a thread portion having a size of 0.3 mm or more and 2 O mm or less is formed below the container, and the same labeling as that of the side portion of the container is formed at the thread portion. Is melted from the bottom part of the container When resin is injected, the molten resin flowing from the bottom part to the side part flows not only to the side part but also to the threaded part, so that the label is turned over or the label side (female side) (Between the inner surface of the mold and the label) can be prevented.
- the container of the present invention has a threaded portion, so that the threaded portion plays the role of a shampoo that adjusts the dimensional error. As a result, the design of the container is not impaired.
- an in-mold label type plastic container manufactured by an in-mold label type manufacturing method in which a molten resin is injected into a cavity to perform labeling simultaneously with molding of the container.
- a flange is provided at an upper end of a side portion of the container.

- the thickness of the label is 150 ⁇ or less.
- the part with and without the label The width of the gap through which the injected molten resin flows will differ greatly, and of course, the flow rate of the molten resin will also differ depending on the presence or absence of the label. If there is a large difference in the flow velocity of the molten resin in this way, there will be a difference in the arrival time of the resin at each part of the container, and the resin that first arrives at a certain part and the resin that arrives after that will be combined In other words, a so-called eld is generated at the flange, which may be a fatal defect that the flange breaks when the lid is sealed.
- the thickness of the label is 150 ⁇ m or less, there is no large difference in the flow velocity of the molten resin between the portion having the label and the portion not having the label. As a result, the occurrence of a so-called weld can be prevented.
