Abstract

The utility model relates to a structure for an automatic opening mouth of a bag, wherein, one or a plurality of spring steel sheets are utilized as a primary element to automatically open the mouth of a bag body after the bag is opened. The spring steel sheet is especially arranged between a bag body of the utility model and a main body. When the bag body is closed, the spring steel sheet can be bent (and must bend inward) and hidden in the interior because the spring steel sheet has the elasticity and an arc-shaped design on the surface. When the bag body is opened, the spring steel sheet arranged in the bag can thereby, stretch and provide a stretched opening of the bag body for users to take, fetch or load goods.

Description

Automatically spring open sack formula structure

The utility model belongs to the daily living article field, particularly a kind of sack formula that automatically springs open framing member of bag.

Knapsack on the market is multifarious at present, have and only possess a sack, two several sacks ... so the sack of a plurality of sacks possessed, its sack except can doing to fasten with fastener, also can be with slide fastener as sealing, but no matter be to seal as fastening or slide fastener conduct with fastener, all to hand sack be opened passively, just to take out article at every turn, all need again sack to be strutted to seek article, in the time of so will taking the article in the bag at every turn, will repeat to do an action---with hand sack is strutted and seek article or directly grope article, therefore, the design people justs think, if can omit with hand sack is strutted this action repeatedly, can economize the next action that at every turn all will repeat, also can save and a bit take the article time and/or grope the article trouble, the very fast target item that finds; The design people is engaged in the bag manufacture for many years, constantly asks innovation, asks progressive, can enjoy life style more easily in order to make the customer, has this creation to automatically spring open the birth of sack formula structure finally.

The purpose of this utility model is to propose a kind of structure of being made up of pkt. flap, bag, body and spring steel plate that automatically springs open the sack formula, and it has easy to use, time saving characteristics, thus solved the existing in prior technology problem.

The technical scheme that the utility model adopted is, it is provided with one or several openable bags on the body of structure, it is characterized in that:

Between the pkt. flap of this bag and structure body, be provided with spring steel plate, and the section of this spring steel plate is the curved arc shape, make that bag can be with this spring steel plate bending when closure state, and when opening bag, then the elastic force by this spring steel plate flicks pkt. flap.

The utility model is easy to use, and saves time, and has avoided repeating loaded down with trivial details action at every turn.

Fig. 1 automatically springs open the embodiment block diagram of sack formula structure for the utility model.

Fig. 2 closes the drawing in side sectional elevation that spring steel plate when closing state is the U font for the utility model as sack.

Fig. 3 opens the straight drawing in side sectional elevation of sack rear spring steel disc support for the utility model.

Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now, the utility model is a kind of sack formula structure that automatically springs open, it can allow pkt. flap automatically spring open when opening bag, making things convenient for user's bag interior article of taking, or article is put into bag.

Having the back type structure of a plurality of bags, and be that embodiment illustrates in the embodiment of the present utility model explanation with the zip mode sack.

As shown in Figure 1, structure of the present utility model can be travelling aviation case, document envelope, knapsack, school bag, shopping bag, travelling bag ... wait object; Its body 6 sides at structure are provided with bag 8, and box body of these bag 8 likeness in form comprises a pkt. flap 10 and the slide fastener 4 that is located at the sack edge, and the lateral surface of this bag 8 is linked to body 6; The preferred embodiment of pkt. flap 10 is to make with the hard material moulding, and make its lateral surface towards body 6 the place aheads, opening 12 edges of bag 8 are with the drawing instrument of slide fastener 4 as the sealing sack, and all be sewed with a soft catch 14 at the dual-side of pkt. flap 10 and body 6, be linked between pkt. flap 10 and the body 6 by this catch 14, make pkt. flap 10 after being opened into the limit, be able to be held and can not enlarge the width of its unlatching again by catch 14, thereby opening 12 sizes that restriction pkt. flap 10 can be opened have the disappearance that prevents that bag 8 from causing article to drop out when opening simultaneously.Aforesaid catch 14 is the design of interlayer, they can be at two side-lens 14 or wherein in the interlayer of a catch 14 spring steel plate 2 are set, this spring steel plate 2 can be to be strip or in the form of sheets, and it is shaped to section is the curved arc shape, one end of spring steel plate 2 is located at pkt. flap 10 side inboards, and the other end then is linked to bag 8 inboards of bag 8 openings 12 opposite ends.

As shown in Figure 2, when bag 8 is when closing shape, be located at in-to-in spring steel plate 2 owing to have the design that splendid flexible and surface is curved arc shape, can make its recessed direction bending, and then make spring steel plate 2 be forced to be stressed and be U font body and store elastic force toward curved arc shape; And in case when opening sack, then spring steel plate 2 suffered pressure are removed, its stored elastic force will discharge and return back to the former long status that stretches.As shown in Figure 3, the elastic force of spring steel plate 2 can drive the pkt. flap 10 that is linked to spring steel plate 2 one ends and eject, and bag 8 also just is and struts shape, and the user is just directly picked up the article in the bag, or article are put into bag.

But above-described only is a possible embodiments of the present utility model, and the equivalent structure that utilizes the utility model specification sheets or claims scope to be done such as changes, and ought to be included in claims protection category of the present utility model.
