Abstract
The invention provides hollow plastic chopstick of disposable anti-slip and preparation method thereof.Chopsticks comprise shell, die cavity and sealed end, and described shell is totally-enclosed, and described sealed end is arranged on the end position of shell, also comprise the gripping end that anti-slip section is arranged on chopsticks shell, are filled with compressed air in the described die cavity of shell parcel.The preparation method of chopsticks comprises the following steps: 1) in blank mould, complete preformed member; 2) sealed end is extruded in preformed member one end; 3) be filled with compressed air at preformed member in chopsticks mould, complete the chopsticks shell closed one end; 4) sealed end is extruded, by compressed air sealing in die cavity at the chopsticks shell other end.Technical scheme provided by the invention avoids wooden bamboo matter chopsticks to be needed through bleaching, and be detrimental to health and raw material use the environmental disruption caused, recovery and the recycling of raw material can be realized, hollowly be filled with compressed air, plastics light weight and materials are few, preparation method is simple and with low cost, is suitable for single use, has the excellent market competitiveness.
Description
Technical field
The present invention relates to hollow plastic chopstick of disposable anti-slip and preparation method thereof.
Background technology
Asians uses chopsticks to be mainly take food instrument, and in general simple and easy fast food or take-away sun drink industry, the disposable disposable chopsticks just abandoned are widely used to lower wage cost.The disposable chopsticks major part that current market uses is all bamboo chopstick or wood chopsticks, but because the manufacturing process of bamboo wood chopsticks widely uses bleaching drug and anticorrisive agent, makes it be absorbed by the body and health risk taking food in process.And on the other hand the bamboo hair of bamboo chopstick and bamboo thorn, probably make it stab oral cavity taking food in process.And make bamboo wood chopsticks and need cut down a large amount of forest, destroy nature and consume the energy.Meanwhile, current bamboo wood chopsticks surface is easily hidden after bacterium cannot be reclaimed and is made raw material recycling or purged and packed recycling, is unfavorable for the universal use of this tableware of chopsticks.
A kind of air inflation hollow chopsticks is disclosed in Chinese patent ZL200920051868.9, its profile is identical with the profile of common chopsticks, chopsticks are hollow Pneumatic chopsticks, hollow Pneumatic chopsticks establishes Packed hollow die cavity, be filled with compressed air by special technique in the hollow die cavity of sealing, hollow Pneumatic chopsticks is manufactured by nontoxic silica gel material.Provide in the embodiment of this patent in Pneumatic chopsticks and be provided with sticking plaster enhancing and do not provide preparation method, be difficult to realize and assessment.
Summary of the invention
The object of this invention is to provide hollow plastic chopstick of disposable anti-slip and preparation method thereof, in order to solve defect and the deficiency of the existence of above-mentioned prior art.
For achieving the above object, the hollow plastic chopstick of disposable anti-slip of the present invention, it comprises shell, die cavity and sealed end, and described shell is totally-enclosed, and described sealed end is arranged on the end position of shell, is filled with compressed air in the described die cavity of shell parcel;
Further, described sealed end comprises two that are arranged on shell two ends;
Further, also comprise anti-slip section, described anti-slip section is arranged on the gripping end of chopsticks shell;
Further, the material of described shell and sealed end is thermoplastic, is selected from the plastics of food security permission to use as polypropylene or polyethylene; , described material source is extensive, with low cost and can recycle and reuse;
Further, the compressed air in described die cavity is 140 kPas-300 kPas, and this compressed air strengthens the working strength of chopsticks, the not easily flexural deformation when clamping food simultaneously, and the gripping process coordinating the anti-slip tank of gripping end to make is more effective, more firmly;
Further, the cross section of described anti-slip section is progressive to reduce and gripping top is minimum;
Further, the cross section of described shell can be circle, triangle, square or other polygons, and the material because of described shell is convenient to shaping, therefore can manufacture and design and have more attractive in appearance and outward appearance that is individual character;
The preparation method of the hollow plastic chopstick of disposable anti-slip of the present invention, it comprises the following steps:
1) preformed: heating raw materials completes both ends open tubule shape hollow preforms through injection moulding in blank mould;
2) position, one end sealing: step 1) preformed member position, one end extrude sealed end;
3) blow molding: step 2) complete one end sealing preformed member be filled with compressed air blow molding complete in chopsticks mould one end close chopsticks shell;
4) other end position sealing: step 3) chopsticks shell another position, openend extrude sealed end, by compressed air sealing in the die cavity of chopsticks shell, complete the hollow plastic chopstick of disposable anti-slip;
Further, step 1) described preformed member not yet cooling die plasticity time carry out step 2) and step 3);
Further, step 3) the chopsticks shell of described one end sealing carry out step 4 when not yet cooling and losing plasticity);
Further, step 3) described chopsticks mould comprises anti-slip section structure;
Further, step 3) operating pressure be 140 kPas-300 kPas;
Further, step 3) compressed air be equal to step 4) compressed air.
The advantage of the hollow plastic chopstick of disposable anti-slip of the present invention is:
1) lightweight, reduce cost of transportation;
2) make after can reclaiming raw material recycling or purged and packed reuse;
3) do not need through bleaching, and be detrimental to health;
4) surface smoothing not easily hides bacterium;
5) the anti-skidding design of front end is beneficial to clamping food;
6) also there is appropriate elasticity while strengthening chopsticks hardness by compressed air, saved the consumption of raw material, alleviate the quality of chopsticks, and gripping has been more firm;
7) selection due to plastics is extensive, can prepare the chopsticks of many performances according to the requirement of purposes;
8) preparation method is simple and with low cost, is suitable for single use, has the excellent market competitiveness.
