Inward-curled-edge cylinder container

Abstract

Disclosed is an inward-curled-edge cylinder container. The top of a body is provided with a top reinforcing rib inwards extending and bending. The outer diameter of the body is gradually contracted from top to bottom. The outer diameter dimension of the bottom position of the body is between the outer diameter dimension of the top position of the body and the inner diameter dimension of the top reinforcing rib at the top position of the body. An outer superposition edge at the superposition bonding seam position of the body presses an inner superposition edge, and the bottom section of the inner superposition edge is partially provided with a notch. The outer superposition edge comprises an outer-layer outer side piece and an outer-layer inward curled piece. The inner superposition edge comprises an inner-layer outer side piece and an inner-layer inward curled piece. The bottom section of the inner superposition edge is partially provided with the notch, so that the inner-layer inwardcurled piece is also provided with a notch. A partial structure formed through superposition bonding of the outer-layer outer side piece, the inner-layer outer side piece, a vertical folded piece andthe outer-layer inward curled piece from outside to inside in sequence is formed on the section of the superposition bonding seam position at the bottom of the container.

Description

technical field [0001] The invention relates to an inner crimping cylinder container. Background technique [0002] Most of the popular food cylinder containers on the market today, such as "potato chips" tubes, are mostly hard paper tubes processed by winding thin paper tapes, which consume a lot of raw paper materials and the outer surface of the hard paper tubes needs to be artificially pasted. Patterned facial paper costs raw materials and labor; another conical food cylinder container, such as "instant noodle cup" or "instant noodle tube", is a piece of printed paper that is rolled into a one-time roll with a self- A cylindrical container with a top-to-bottom adhesive seam, but the side shrinkage angle of the cylinder is generally large, resulting in an unsightly appearance and because the side shrinkage angle of the cylindrical container is small and the bottom area is small, it is unstable to place on the table. The large side contraction angle also leads to the resu...

Problems solved by technology

[0005] The beneficial effects provided by the present invention are: the inner crimping cylinder well overcomes the defects of existing conical food containers such as "instant noodle cup" or "instant noodle cylinder" with obvious large and small heads: the center of gravity is relatively high, the base Small, unstable, and unsightly, and due to image 3 The obvious conical structure of the large and small heads in the prior art shown in the prior art will make the upper side of the expanded prototype plate of the container have a convex arc shape and a lower side concave arc shape. The slope of the left and right sides of the cylinder container is relatively large, which will inevitably cause more material waste of leftover materials when the expanded prototype plate of the cylindrical container in the prior art is cut. Obviously, the problem of this material waste can be solved in the patent of the present invention. A very reasonable and effective solution is obtained; at the same time, the patent of the present invention also overcomes the hard straight cylinder containers that are commonly processed by winding thin paper tapes in the existing market, such as "potato chips" and "wine hard cylinders". Defects of "box": extremely slow production efficiency, very expensive base paper, and manual pasting of the outer surface paper, which consumes both materials and labor, and the efficiency is low. The manual pasting is not smooth and unsightly. Not easy to put in car cup holder
