Description

  The present invention relates to a container, and in particular, to a paper container used for storing a liquid or a food material.

  Paper containers such as small plates, platters, paper cups, or food trays are widely used because they are convenient to use and can suppress an increase in plastic materials that cannot be decomposed.

  Looking at folding plates, which are conventional products, paper trays are currently sold in the market, but this is a folding plate that takes a long time to produce a mold for folding.

  Therefore, since processing is difficult and it sticks between the bent parts, there are problems such that the sticking part is easily peeled off and sticking is difficult.

  The paper dish and bowl of the Chinese Patent Registration No. M240929 are formed by cutting and cutting the paper dish together, and then form a separable outer ring piece and an inner bottom plate at the edge and the central part, respectively.

  A wall having an inclination and an outer folding edge are extended in an order toward the outside through a central hole of the outer ring piece.

  The wall having an inclination and the outer folding edge are cut into appropriate portions to form a cut-out opening, and a bundle-shaped annular piece is attached to both sides of the cut-out opening. Form.

  Further, the bottom surface of the wall having an inclination is combined with an adhesive portion formed on the edge portion of the inner bottom plate.

  However, in the above-described structure, the outer ring piece and the inner bottom plate must always be connected by sticking the wall having the inclination and the sticking portion to each other.

  Therefore, when mass-producing the above-mentioned product, it can be reliably adhered only by an artificial adhesion method.

  When produced on a machine, the product must not only be formed in the same way as the original design, but also because the strength of the upper edge of the dish is insufficient.

  As disclosed in FIG. 1, a paper plate 91 and a film 92 are formed in combination.

  The paper plate 91 is provided with a connecting portion in which a portion for storing food is extended outward.

  A corner portion 93 of a plastic material is provided at a portion where the angle is changed by connecting to the connection portion formed on each side, and a complete outer edge portion is formed outside the paper plate 91.

  If the film 92 is melted with a cup-sealing machine and connected to the outer edge of the paper box, the ingredients inside the paper plate can be protected, and the soup can be prevented from leaking outside. it can.

  However, since the corner portion 93 is provided at the corner portion between the two adjacent connection portions, the corner portion 93 is formed by any technique from the plane of the two connection portions adjacent to each other. Are also formed high or low (see partially enlarged view).

  Therefore, even if a film is provided, the foodstuff inside the paper dish cannot be reliably sealed.

  Moreover, a general film achieves the objective of sticking on the outer peripheral edge part of a paper plate, covering, and sealing in the state heated and pressurized.

  However, when the paper plate is rectangular, the strength is limited, and in the process of providing a film on the paper plate, when the connection part receives pressure, it sinks downward, and a part of the side in the longitudinal direction on both sides is stuck, The situation where it is not sticking occurs, resulting in a state where the sealing property and certainty of the film are insufficient.

  An object of the present invention is to provide a container that can be easily and quickly manufactured and has a preferable strength.

Therefore, as a result of intensive research in view of the drawbacks found in the prior art, the present inventor comprises a paper body and an adhesive thin film formed on the body,
The main body focuses on the point that the problem can be solved by the structure of the container in which an adhesive layer made of biodegradable plastic is provided on the outer peripheral edge such as the bottom or upper edge, and the present invention is completed based on such knowledge.

Connect correspondingly.

  In the container according to claim 3, the main body according to claim 1 folds some edge portions in order, and at the corner between the edge portion adjacent to the upper edge portion of the edge portion. An adhesive layer is formed integrally.

  In the container according to claim 4, the pressure-sensitive adhesive layer according to claim 3 is integrally formed and extended to the outer edge of the end edge to form a reinforcing part, and the end of the reinforcing part extends downward. Thus, the hook portion is formed beyond the end edge.

  In the container according to claim 5, the adhesive layer in claim 3 is integrally formed by extending to the bottom surface of the end edge portion, covers the end edge portion, and the end of the end edge portion of the adhesive layer is downward. And a hook portion is formed beyond the edge of the edge portion.

  The container according to claim 6 is such that the main body according to claim 1 is connected to a hollow cylindrical shape so as to surround the corresponding side, and an adhesive layer is formed on each of the upper and lower end edge surfaces to form a cup. Can do.

  Since the container according to the present invention has a simple structure, it has the effect that it can be automatically produced in large quantities and the cost can be reduced.
