Abstract

The invention provides a folding type antimicrobial plastic lunch-box which is manufactured by carrying out injection moulding on folding resistant antimicrobial resins. An unequal thickness design is adopted for an injection moulding mould of the folding type antimicrobial plastic lunch-box; 12 folding seams are designed on the mould; and after the folding type antimicrobial plastic lunch-box subjected to injection moulding is demoulded, the hot folding seams are folded for 2-3 times repeatedly at once while the folding type antimicrobial plastic lunch-box is hot, and the folding angle is 80-90 degrees. The folding type antimicrobial plastic lunch-box can decrease the occupied space when the lunch-box is empty, thus being convenient to store and carry the empty lunch-box. In addition, the folding type antimicrobial plastic lunch-box has the characteristics of acid and alkali resistance, corrosion resistance, antibiosis and mouldiness resistance, and is applied to business trips and marching wars.

Description

The folded antibacterial plastic lunch box

Technical field

The invention belongs to the plastic products production technical field, relate to a kind of folded antibacterial plastic lunch box.

Background technology

At present, the plastic lunch box that uses on the market generally is a kind of rectangular structure, and lunch box can not fold, can not be antibiotic, and empty lunch box takes up room bigger, carries very inconvenient and plastic lunch box also grows mould easily.

Summary of the invention

In order to overcome the deficiency of existing plastic lunch box, the invention provides a kind of folded antibacterial plastic lunch box.This lunch box folding convenient, antibacterial and mouldproof has the effect that protects the health.After the folded antibacterial lunch box is folding, takes up room and dwindle several times, the storage and the transportation that provide travel row and march field operations and empty lunch box bring great convenience.

The specific embodiment:

Injection molding method is produced the folded antibacterial plastic lunch box

(1) opens system folded antibacterial plastic lunch box injection forming mold (opening the system injection forming mold) according to structure shown in Figure 1, the characteristics of this mould are to have adopted not uniform thickness design, and 12 road folded seam have been designed on the lunch box mould, the thickness of lunch box is 0.5～4mm, the thickness of each folded seam is 0.3～1.5mm, and width is 2～8mm.

(2) (for example: a kind of folding-resisting antibacterial resin, the patent No. is: 200910246741.7) as the use in injection molding raw material to select folding-resisting antibacterial resin for use.

(3) folding-resisting antibacterial resin is added in the loading hopper of injection machine, open injection machine, the forming temperature of control injection machine is: one section, 220～225 ℃, two sections, 225～230 ℃, three sections, 230～235 ℃, four sections, 235～240 ℃, the control injection pressure is 30～45Mpa, with folded antibacterial plastic lunch box injection forming mold, folding-resisting antibacterial resin is processed into the folded antibacterial plastic lunch box, from mould, takes out the folded antibacterial plastic lunch box, immediately while hot with the folded seam of lunch box folding 2～3 times back and forth, folding angle is 80～90 degree, and lunch box is finished product after pruning.

The testing result of lunch box is as shown in table 1

Table 1, folded antibacterial plastic lunch box bacteriostatic test and folding tester be list as a result

Sequence number	Test item	Testing result
				1	Anti-staphylococcus aureus performance test	Bacteriostasis rate 〉=98%
2	Anti-pneumococcus performance test	Bacteriostasis rate 〉=98%
			3	Anti-gram-Negative bacillus performance test	Bacteriostasis rate 〉=98%
4	Resisting gram-positive bacillus performance test	Bacteriostasis rate 〉=98%
			5	Chinese People's Anti-Japanese Military and Political College's enterobacteria performance test	Bacteriostasis rate 〉=98%
6	The anti-salmonella performance test	Bacteriostasis rate 〉=98%
			7	The anti-candida albicans performance test	Bacteriostasis rate 〉=98%
8	The test of antifungi performance	0 grade
			9	Folding resistance can be tested	〉=2 ten thousand times

Remarks: above bacteriostatic test carries out with reference to QB/T2591-2003 antibiotic plastic anti-microbial property test method and Ministry of Public Health's " disinfection technology standard " third edition first fascicle (test requirement specification), and sample is taken from the antibiotic plastic lunch box.

The production method of above-mentioned folded antibacterial plastic lunch box not only is confined to the production of antibiotic plastic lunch box, uses this method can also produce all folded antibacterial plastic products such as various folded antibacterial plastic tub, folded antibacterial plastic stool and folded antibacterial plastic bath tub; Also folding-resisting antibacterial resin can be changed into plain polypropylene resin or polyvinyl resin, produce various common folding plastic goods.

The invention has the beneficial effects as follows that the folded antibacterial plastic lunch box can reduce taking up room of empty lunch box, bring great convenience for the storage and the transportation of empty lunch box.In addition, the folded antibacterial plastic lunch box also has acid and alkali-resistance, corrosion-resistant, and the characteristics of antibacterial and mouldproof are highly suitable for out of town trip and the march use of fighting.
