Lidded dixie cup

Technical field

The present invention relates to Lidded dixie cup, particularly relate to following dixie cup: the inventor is the improvement invention of patent application 2000-82701 formerly, the dixie cup of a large amount of band vinyl covers that use in fast food restaurant and recreating facility etc., do not use the vinyl cover of system in addition, be integrally formed in lid made of paper on glass cylindrical shell body and dixie cup to be opened/closed.

Background technology

Be 184.3g as automatic vending machine and other coffee with the low capacity dixie cup that cup uses at present, do not use lid, and in the fast food restaurant or mainly to use the drinking water dixie cup be jumbo dixie cup more than the 255.1g in the leisure place, normally provide with the state that covers vinyl cover behind the content of packing into again.

Along with environmental protection reveals as social concern, plastic containers are subjected to the restriction of law, can ban use of synthetic resin article in food from now on, therefore press for the problem of improving vinyl cover at present.

On the viewpoint of health, holding under the situation that cup moves, lid also is necessary, therefore be used to improve the scheme of lid and research from before just attempt always.

Dui Ying example of the prior art therewith, as shown in Figure 6 and Figure 7, make in the following manner: although when severing is used to make the body paper of cup so that cover 22 mode severings to the top of cylindrical shell 21 side, but lid is highly slightly more outstanding than the center of circular plate type, make the lower side of eccentric plectane form fold line 23 by force in the folding obliquely mode of cylindrical shell, the lower side that makes plectane is by beginning folding and the upper inner that outstanding upper side is folded to cup being covered from cup cylindrical shell downside, and make the remainder of the cap that removes cup cylindrical shell upper end periphery load onto plastic edge 24, adhesion is got up, inboard at the edge forms engagement protrusion 25, when folding thrust cap 22, lid can not be thrown off by engagement protrusion 25.

Although this is formerly invented and has the advantage that does not need other lid,, on paper, use the effort of plastic material not thorough and make to want to eliminate because utilize plastic edge 24.And during the cup after reclaiming use, must separate plastic material separately, very trouble.And when burying, be not easy to rot, when burning, can produce poison gas, cause problem of environment pollution caused.

After the applicant considers these problems in " dixie cup with cover itself " of the korean patent application of first to file 2000-82701 number, as shown in Figure 4 and Figure 5, the dixie cup general with the past is identical, though by making glass cylindrical shell 11 upper ends curl into crimped edge 14 laterally, but only make just over remove to form cover 12 part remaining half curl into crimped edge 14, along by making the remainder that not have to curl become circular plate type and to the outstanding lid 12 that forms the folding glass of body paper of fold line 13 formation of glass cylindrical shell itself in top.And, for behind the lid 12 that closes closed-cup, form two outstanding edge 15 owing to can make lid be fixed on the upper inner of glass cylindrical shell 11 in that cylindrical shell is inboard, both sides at lid form along the folding shank 16 of fold line by outstanding, so can make and cover 12 and open, can make again and cover the jail and be entrenched in regularly between two beads 15, in order under the state of closing cap 12, also to utilize suction pipe to drink easily, and form " ten " notched cut portion in the top of lid one side.

Though yet this is formerly invented and is not had above-mentioned problem in the use, but when making the structure loam cake closed, to have to form two raised lines in order coupling together securely, because of increasing the machining operation machinery to be complicated, thereby cause the problem that cost increases in the inboard of cylindrical shell.

Summary of the invention

The present invention is except in view of above-mentioned the problems of the prior art point, also the problem in view of invention formerly proposes, though on the periphery of cup cylindrical shell upper end, make the upper end curl into the edge, but only make exceed slightly the part that remove to form lid and remaining half inwardly curl into the edge, borrow than when folding pressing cover, the function of auxiliary section is finished at the edge that curls, the following rear flank that is embedded in this edge mate portion in the circumferential edges that makes lid is folded up, for covering under the closed state, utilize suction pipe to drink easily, and form the cross cut in the upper side of lid.

The specific embodiment

Describe the present invention in detail with reference to the accompanying drawings and according to preferred embodiment.

At first in order to help to understand the present invention, and the manufacture process of diagrammatic illustration dixie cup.Applying thin ethylene resin layer in order to prevent to leak on the body paper outside of reel state handles, on the cup cylinder expanded view outside with behind proper alignment photogravure (connecting hectographic printing under the language font situation on a small quantity) the formation pattern, utilize the cup body paper of the die-cut cup of perforating press cylinder deployed condition, cause cup with the dixie cup forming mechanism again.At this moment in the dixie cup forming machine, carry out as mentioned above like that the cup body paper of severing supply with the heating of columnar cylindrical shell forming process of bonding one-tenth and bottom one by one automatically after laminated and adhere to operation, adhere in the operation in described heating, twist in coating on the banded reel the body paper of vinyl be contained in top, dixie cup forming machine side and launch to supply with the limit continuously and cut with perforating press and form the bottom, curl the simultaneously circumferential edges of above-mentioned bottom, be embedded in then be shaped in the cup tube that moves by an above-mentioned tubular operation after again heating adhere to.

Adhere in the operation in the bottom heating, carrying out described step up and down simultaneously, carry out a preheating by heater, making the upper end of cup (be the inboard in the present invention) laterally by secondary coil (curling) operation slightly curls, curled to the inside with thick warpage degree in the bottom, under the state that surrounds the part of warpage below the bottom of having loaded onto, curl.

At this moment, because the heater of dress self-heating on the template lower inside that lower side is curled to the inside, the limit is inwardly curled glass cylindrical shell bottom, and the limit makes the vinyl coating become the state that partly dissolves by heating, adheres to operation by the pressurization of following and adheres to sleekly.

Lower rim by the heating roll-in of carrying out rotation and revolution under the state of inlaying below bottom the cup cylinder of lower side curling abundant preheating to the inside promptly is equipped with in the outside, cup cylinder bottom by pressurization adhesion operation like this and finish the dixie cup manufacturing.

In the above-mentioned cup manufacture process, make by above-mentioned a series of manufacturing process, under the deployed condition of the cup of the cup body paper that is shaped during the severing punching and shaping, though make central upper end protrude circular plate type, but make outstanding height be projected into 3/5 height of whole plectane, lower side is so that the mode that lower side 2/5 becomes cup tube 1 itself forms fold line 3 by force and makes along plectane covers 2 and fold up, in the dixie cup of making like this, because the remainder of the lid 2 by making the upper end periphery that removes above-mentioned cup cylindrical shell 1 inwardly curls into crimped edge 4, so decapacitation has outside the internal action that contacts with the lip softness, can also work as the gomphosis part of not throwing off connection in flype 2 backs, and, just can drink easily by puncture opening 5 with suction pipe and make under the lid closure state because form the cut 5 of " ten " font in the upper side of above-mentioned lid.

Like this present invention of Gou Chenging in rest facility on fast food restaurant and high way road etc. when client provides beverage, pack into after the beverage, owing to only push the lid 2 of vertically-arranged simply, and one edge fold line 3 folding, be entrenched in bottom on one side by the crimped edge 4 that in cup cylindrical shell 1 upper side circumferential edges, curls into, make lid closed, so can remove the inconvenience of opening the lid that alternate manner forms or closing lid that alternate manner forms etc.
