405 results about "Cardboard box" patented technology

Cardboard boxes are industrially prefabricated boxes, primarily used for packaging goods and materials and can also be recycled. Specialists in industry seldom use the term cardboard because it does not denote a specific material.

Insulated food crate

An insulated food crate comprises a generally rectangular, typically cardboard box having separable top and bottom portions with double walls providing insulative properties and also insulating inserts fitted into the top and bottom portions. The box may also have ventilation holes or slots and / or compartments for serving utensils and may be disposable. In alternate embodiments, the insulated food crate may be made from a heat-resistant composite material, such as a reinforced plastic or stainless steel, as a more permanent, durable, and reusable solution. This inexpensive, accessible catering box keeps hot foods hot and cold foods cold while allowing quick and easy access to the foods inside.

Flexible preprinting cardboard box, production method and production equipment thereof

The invention discloses a flexibly pre-printed paper box, a manufacture method and a manufacture equipment thereof; the paper box has a box body consisting of a printed sheet, corrugated paper, inner paper and in some cases core paper; color patterns on the printed sheet are flexibly printed on the printed sheet before the paper box is manufactured. The manufacture method consists of a manufacture method of flexibly printed paper sheet and a manufacture method of the paper box; firstly the color patterns are manufactured on the printed sheet with a rotary flexographic press; then bright oil is applied, and then the printed sheet, the corrugated paper and the inner paper are made into the paper box by adopting a corrugated paper manufacture device; some paper box also comprises the core paper. The manufacture device consists of the rotary flexoographic press, the corrugated paper manufacture equipment and a die-cutting machine. Adopting the method and the equipment of the invention, the manufactured paper box is green and environmental protective, nice in printed patterns, high in compressive strength, convenient in lifting and low in reject rate; compared with paper boxes which are printed with offset printing and directly with flexible plate of the same quality requirement, the paper box of the invention has lower cost.

Heat shrinkable polyester film

A heat shrinkable polyester film of the present invention has a transverse tear defect percentage of about 20% or less as determined in the following vibration test: the film is rolled into a tubular shape, two of its opposite edges bonded together, and then the tubular film is placed around a vertical stack (total weight: 660 g) of three food container cans each having a diameter of 72 mm and a height of 55 mm; the can stack with the tubular film placed therearound is passed through a shrink tunnel to shrink the tubular film onto the can stack; a total of 18 packs of such can stacks are placed into a cardboard box having a length of 455 mm, a width of 230 mm and a height of 165 mm (6 packs in the length direction by 3 packs in the width direction), and the cardboard box is sealed; the cardboard box is vibrated along the width direction for 30 min by a stroke of 50 mm and at a vibration rate of 180 reciprocations / min, after which the transverse tearage of the tubular film is visually observed; and the transverse tear defect percentage (%) is determined based on the number of defective packs per 18 packs, wherein the defective pack is any pack having a tear flaw of 30 mm or longer along a can periphery. The heat shrinkable polyester film of the present invention has a good shock resistance during shipping especially under low temperatures, with a good finish after shrinkage and a sufficient solvent adhesiveness. Thus, the heat shrinkable polyester film of the present invention is suitable for use in a multi-packaging label for packaging, inter alia, a stack of cans.

Method and device for making box of corrugated cardboard sheet

Disclosed is a method for producing a cardboard box by performing a box-making process of a corrugated cardboard sheet which is formed to have dimensions of a plurality of cardboard boxes wherein the yield of the cardboard sheet and the production efficiency are enhanced and a countermeasure can be taken against paper powder. A method for making a box of a corrugated cardboard sheet by performinga box-making process of a cardboard sheet (S) which is formed to have dimensions of a plurality of cardboard boxes and then cutting the cardboard sheet (S) into dimensions of one cardboard box comprises a step (I) for cutting the cardboard sheet (S) into dimensions of one cardboard box by a cut line (k) in the direction intersecting the conveyance direction (a) along a box making line (PL) after a ruling and grooving step (C) and before a pasting and folding step (E), and a speed increase step (J) for spacing the cardboard sheets (S1) and (S2) thus cut by a set dimension following to the cutting step (I) by increasing the speed of the cardboard sheets (S1) and (S2) while conveying toward a subsequent step.

Folded cushioning material for packaging

A cushioning material for packaging is provided, which is used when an article having a rectangular cross section or a cubic shape is packaged in an outer case, such as a corrugated cardboard box. The cushioning material is suitable for packaging the article therewith in an outer case while an end portion, which has a pair of corner sections, of the article is inserted into and supported by the cushioning. The cushioning material is provided with a grooved retainer (1) and a pair of end support members (2,2) disposed so as to close the ends of both end portions of the grooved retainer (1). The grooved retainer has a raised bottom (10) and two side walls (11,11) and is adapted to receive one inserted end portion of the article having a rectangular cross section or a cubic shape. The end support members each have a plurality of hollow portions (20), which are arranged in parallel in a predetermined direction, and a rectangular cross-section orthogonal to the longitudinal direction of the hollow portions (20). The grooved retainer (1) and end support members (2,2) are formed by folding a single sheet a of a predetermined planar shape along valley-forming folding lines (a1) and ridge-forming folding lines (a2) formed on the sheet. This enables to provide a cushioning material for packaging which has a simple structure and a low bulk specific gravity, and is not likely to deform.
