Abstract
The utility model relates to a structure design of a utensil capable of conducting the vacuum preservation for pre-stored food or articles, which comprises a high-strength plastic film bag, a one-way air guiding valve and a miniature vacuum pump, wherein, the one-way air guiding valve is hermetically connected with the plastic film bag and has communicated air paths, and the miniature vacuum pump is matched with the air valve. The utility model has the advantages of simple structure, small size, convenient use and carrying and low cost, can be independently used to conduct the vacuum preservation and the quality guarantee for articles, can also be matched with the existing article storing utensil, and meanwhile, has the functions of freshness preservation and thermal insulation.
Description
The utility model belongs to the Family Day staple, particularly a kind ofly can store the utensil structure design that food or article carry out vacuum freshness retaining to desire.
In Modern Family's life, all be unable to do without the vessel of storing food, drink or other article when the work of going out, tourism.These vessel are various in style, and the material that it adopts, face shaping are multifarious, and be dazzling, but similar with regard to its function.Mainly act as and contain article, wherein some vessel can closed dust, and vessel that also have some to store food, drink in addition can keep the temperature of certain hour, thermos cup for example, incubation canteen etc.But above-mentioned vessel all can not play fresh-keeping, the effect of guaranteeing the quality to the article of storing.
A kind of vacuum freshness retaining plastic bag occurring on the market recently, is to treat that fresh-keeping article are put in this plastic bag, with a vacuum air pump bag is bled and seals.Though this mode can play preservation to food, does not have heat insulation effect, but also need special, a volume vacuum air pump big, that price is more expensive to carry out air extracting seal.This mode can not satisfy the demand to food heat-insulation, and goes out outside when work is traveled to want that article are carried out air extracting seal at any time also to be difficult to carry out.
The purpose of this utility model is to overcoming the weak point of prior art, design a kind of home-use vacuum plastic housing, this cover structure is simple, volume is little, use easy to carry, cost is low, can use separately article are carried out vacuum freshness retaining, guarantee the quality, also can cooperate existing storer ware to use together, play effect fresh-keeping, insulation simultaneously.
The utility model proposes a kind of home-use plastic sheeting vacuum freshness retaining cover, it is characterized in that it comprises highstrenghtpiston's bag film, unidirectional guide valve that communicates with this plastic film bag sealing-in and gas circuit and the minipump that matches with this air valve.
Using method of the present utility model is, treating that article fresh-keeping, that guarantee the quality put into plastic bag, sack sealed earlier again, and sealing can be adopted variety of way, for example heat-sealing, high-frequency heat sealing or mechanical seal etc.At last minipump is aimed at unidirectional guide valve and bled, its vacuum state that acquires a certain degree is got final product.
The utility model also can with the supporting use of general storer ware, its method is to treat that earlier article fresh-keeping, that guarantee the quality contain in the general vessel, again these vessel is put into plastic film bag of the present utility model, seals as stated above, bleeding gets final product.If the vessel of putting into the utility model plastic bag are insulating utensils, then can play insulation, fresh-keeping, the effect of guaranteeing the quality simultaneously.
Plastic sheeting of the present utility model should have low permeation, infiltration, high-intensity performance, also should be nonpoisonous and tasteless if store food.
The said vacuum pump of the utility model is a kind of of manual suction pump, water fluidic pump or mechanical pump, and said unidirectional guide valve adopts ball-type or film-type structure, and main sealing member (ball or diaphragm) adopts high flexibility natural rubber or plastic, rubber to make.
The utility model is simple in structure, volume is small and exquisite, and is easy to use, with low cost, have sealing, fresh-keeping, guarantee the quality, multiple function such as insulation.Can use separately, also can cooperate the storage vessel of various anti-certain intensity to use together, be that the indispensability of life at home, field work, out on tours makes things convenient for apparatus.
Brief Description Of Drawings:
Fig. 1 is a kind of example structure of the present utility model and running condition figure.
The utility model is designed a kind of plastic sheeting vacuum freshness retaining embodiment, and its structure and running condition are described with reference to the accompanying drawings as follows as shown in Figure 1:
Present embodiment is by high strength non-toxic plastic bag 1, goes up unidirectional guide valve 2 that sealing-in and gas circuit be communicated with and miniature manual suction pump 3 compositions that match with this guide valve with this plastic bag bottom.Its running condition as shown in Figure 1, put into a thermos cup 4 that fills food in the plastic bag earlier, thermal cup cover 41 leaves a slit earlier, again plastics sack 11 is carried out heat sealing, then manual suction pump 3 is aimed at unidirectional guide valve 2 usefulness on hand, lower pumping 20～30 times, the food of thermos cup can increase temperature retention time like this vacuum freshness retaining again, prevents food spoilage.
