Abstract

The utility model relates to a collapsible water bag, particularly a kettle used for carrying water. The utility model comprises a skin layer whose front and back surfaces are flexible, the upper part of the skin layer is molten jointed an opening which is provided with an eye-shaped shoulder, the bottom of the skin layer is molten jointed a flexible bag bottom which is a half-moon involution and is molten stuck with waterproof membrane in advance, and the both vertical sides of the skin layer is sealed by the hot melting. When the water is injected, the utility model is in a standing bottle shape. When the water quantity is decreased, the skin layer clamps tabularly, and can be folded because of the flexibility. The main purposes of easy carrying and space saving are achieved.

Description

Collapsible water bag

Water is one of human body three big key elements, and health can not lack of water, and especially when outing mountain-climbing out, the traveller need wear kettle in order to replenishing moisture content, and now is all hollow, shell shaping type with kettle, is ghost though finish off behind the water, still need take onesize space.

The purpose of this utility model is provides a kind of saving space, the travelling kettle that is convenient for carrying.

Now in conjunction with the accompanying drawings in detail, the structure of the utility model water bag is described in detail, in the accompanying drawing:

Fig. 1 is the three-dimensional exploded view of the utility model water bag;

Fig. 2 is the cortex top view of the utility model water bag;

Mouth cylindrical part and bag underneath side elevation view that Fig. 3 fits up and down for the cortex of the utility model water bag;

Fig. 4 is the stereogram of cortex after molten subsides all around of the utility model water bag;

Fig. 5 is the side view of cortex after molten subsides all around of the utility model water bag;

Fig. 6 is the bag end perspective view of the embodiment of the utility model water bag;

Fig. 7 is the front view of the embodiment of the utility model water bag.

Each mark is represented in the accompanying drawing:

1A, 1B cortex 2. mouth cylindrical parts

3. bag end J. kettle body

21. shoulder 31.31A 31B arc lip

B. belt 22. floors

32. broken line BA, BB buckle ear

3A, 3B split lobe H. button hole

P. platform L1, L2 sideline

Two sides cortex 1A before and after the structure of the utility model nestable water bag comprises, 1B, top welding between this two sides has a bottleneck 2, the bottom is molten pastes at the bottom of the semilune bag 3 this cortex 1A wherein, 1B is a pliability, and the molten in advance inboard waterproof membrane (not showing on the figure) of one deck that pastes, for cooperating the set eye shape shoulder 21 of mouth cylindrical part 2, its area can be wide trapezoidal (as shown in Figure 2), the cortex 1A 1B of two sides correspondence is comprised mouth cylindrical part 2(as shown in Figure 1) after the vertical side of set eye shape shoulder 21, carry out the molten subsides of hot pressing, middle minute line position at two sides, front and back shoulder strengthened radial crushing strength and made the mechanicalness back-pressure better every establishing one deck floor 22, really it is closely overlayed fusion, 3 arc lip 31 at the bottom of each molten subsides one semilune of lower inside is split the shape bag, and this arc lip 31 is a downwardly facing opening, two cortex 1A, 3 broken line 32(is split at the bottom of the lobe bag as shown in Figure 1 as Fig. 3 side diagrammatic sketch finding semilune in 3 backs at the bottom of each molten out pocket of 1B bottom) two cortex 1A further, 1B, and splitting lobe 3A arc lip 31A forward is molten being attached on the preceding cortex 1A, split the molten medial surface that is affixed on back cortex 1B of arc lip 31B of lobe 3B backwards, then again with two cortex 1A, 1B both sides vertical edge line L1, L2 is with the from top to bottom molten subsides of straight line of identical welding width, as shown in Figure 4, and its molten back (as shown in Figure 5) of pasting makes two cortex 1A, 1B is superimposed as flat.

The kettle body J(that finishes through above-mentioned operation as shown in Figure 6), when opening bottle cap 23, after the beverages such as injection water, borrow a diffusion such as liquid fluidity, open and press at the cortex 1A 1B and the bag end 3, two cortex 1A then, 1B is subjected to interior pressure and outwards heaves, simultaneously because of two cortex 1A, each moltenly touch 1B bottom inner face at the bottom of the semilune bag 3 downwardly facing opening arc lip 31A and 3 is shown laid flat in boat-shaped face (as shown in Figure 7) at the bottom of spurring bag, and centre fold 32 is with underliing (as shown in Figure 6) at the bag ends 3, this moment two cortex 1A, though being opened drum pressure, the 1B surface rises, but edge is only for planar expanded keeps positive apparent direction level under it, thereby forms a plane eye shape underframe and can halt on plane P.

In addition kettle body J upper side shoulder is respectively established button hole H(as shown in Figure 4), can be for a belt B(as shown in Figure 6) the set buckle ear BA in two ends, BB clip connect, making belt B is an arch carrying handle, so that guide and support.

Claims (3)

1, a kind of can superimposed water bag, it is characterized in that, it comprises the front and back two mutually folded cortexes of corresponding and tool watertight composition, the intermarginal molten symmetrically shoulder that pastes the inclusion mouth cylindrical part on it, lower edge each molten semilune of being made of two downward opening arc lips posted in both sides is to being combined at the bag end of a shape before and after the described cortex, and described two mutually folded cortex sides paste driving fit through molten point-blank from top to bottom.

2, as claimed in claim 1 can superimposed water bag, it is characterized in that described two watertight compositions, for being laminated with the aluminium foil gummed paper.
