Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.

FIG. 1 is a schematic diagram of a structural configuration of a barreled water dispenser barrel according to an embodiment of the present invention; fig. 2 is an exploded sectional schematic view of the hard outer tub of fig. 1; FIG. 3 is an exploded cross-sectional schematic view of the soft liner of FIG. 1; fig. 4 is a schematic perspective view of the bottom cover of fig. 2. The dotted line in fig. 1 represents a water dispenser 100 and a water conduit 101 of the water dispenser 100; referring to fig. 1-4, the present invention provides a barreled water dispenser barrel for a water dispenser 100, which includes a hard outer barrel 1 and a soft inner container 2, wherein the hard outer barrel 1 includes a barrel mouth portion 11, a barrel body 12 and a bottom plate 13, the barrel mouth portion 11 is connected with a top cover 110, the top cover 110 is provided with a first water inlet 111 for inserting the water conduit 101, the bottom plate 13 is provided with a mounting hole 130 at the center, a mounting portion 131 is arranged around the mounting hole 130, the mounting portion 131 is detachably connected with a bottom cover 14, the mounting portion 131 is provided with an annular boss 132 protruding inwards, the bottom cover 14 is provided with a plurality of vent holes 141, the soft inner container 2 includes a container body 21 made of a whole soft material, an inner container head 22 formed by clamping the container body 21 by an inner sleeve ring 221 and an outer sleeve ring 222, an inner container tail 23 formed by clamping the container body 21 by a sealing device 231, the inner sleeve ring 221 and the outer sleeve ring 222 are respectively provided with a second water inlet 223 and a third water inlet 224 for inserting the water conduit 101, the liner head 22 is inserted into the bung 11, and the liner tail 23 is connected with the annular boss 132.

Referring to fig. 1 and 2, the bottom plate 13 may be made thinner except for the mounting portion 131, so that material consumption may be reduced and manufacturing cost may be reduced, and in this case, in order to ensure that the hard outer tub 1 can be stably placed, the tub 12 may be provided with an extension portion 121 on one side of the bottom plate 13, and the height of the extension portion 121 is greater than or equal to the height of the mounting portion 131 after being connected to the bottom cover 14. Thus, the hard outer barrel 1 can be stably placed.

The manufacturing method of the barreled water dispenser barrel provided by the invention comprises the following steps,

step 1, calculating the surface area S1 of the inner cavity of the hard outer barrel 1, and preparing a round soft material, wherein the area S2 of the round soft material is at least 20% larger than the surface area S1 of the inner cavity of the hard outer barrel 1, so that enough soft material for clamping, binding and the like can be ensured outside the sealing device 231 in the process of preparing the soft inner container 2.

Step 2, after the top cover 110 is installed, vertically inverting the hard outer tub 1, that is, as shown in fig. 1, so that the tub opening 11 faces downward, placing the inner collar 221 and the outer collar 222 on two sides of the center of the circular soft material in step 1, respectively, and then using the inner collar 221 and the outer collar 222 to clamp the center of the circular soft material in a sleeved manner to form the inner tub head 22, folding the circular soft material along the inner tub head 22, passing the inner tub head 22 through the installation hole 130, and inserting the inner tub head 22 into the tub opening 11;

the outer diameter (outer circumferential diameter) of the outer collar 222 may be slightly smaller than the inner diameter (inner circumferential diameter) of the barrel portion 11, for example, the outer diameter of the outer collar 222 may be 1-3mm smaller than the inner diameter of the barrel portion 11, so that the inner container head 22 can be easily inserted into the barrel portion 11 by using the gravity of the inner container head 22.

The smallest diameter of the mounting hole 130 (i.e., the inner diameter of the annular boss 132) is larger than the inner diameter of the barrel opening 11, so that the liner head 22 can pass through the mounting hole 130.

Referring to fig. 1 and 3, the inner sleeve 221 mainly serves to isolate the water conduit 101 from the liner body 21, so as to avoid the problem of blockage of the water inlet pipe of the water dispenser due to the fact that negative pressure is generated at the water inlet to adsorb the soft liner body 21. The outer collar 222 is designed to form a sealing opening with the inner collar 221 for clamping the liner body 21, so that the length of the outer collar 222 may be much longer than that of the inner collar 221, that is, the length of the outer collar 222 may be greater than the height of the water conduit 101, and the length of the inner collar 221 is only required to ensure the tight connection between the outer collar 222 and the inner collar 221.

Step 3, injecting water into the circular soft material collected in the step 2 above the mounting hole 130, wherein the circular soft material is gradually filled and attached to the inner wall of the hard outer barrel 1 in the water injection process, when the circular soft material of the hard outer barrel 1 is filled and the water surface exceeds the mounting hole 130, stopping injecting water, attaching the sealing device 231 to the annular boss 132 to clamp and seal the circular soft material to form the liner tail 23, extruding excess water outside the sealing device 231, cutting excess soft material, retaining 10-15mm of soft material outside the sealing device 231, and performing hot plastic package to form a tail part 232, so as to finish the preparation of the soft inner container 2;

the sealing device 231 may be a commercially available plastic bag sealing clip, as long as it can provide enough strength to be clamped on the annular boss 132, so as to ensure that there is enough space around the sealing device 231 to enter the inner cavity of the hard outer tub 1 through the vent hole 141 of the bottom cover 14. The tail material part 232 formed by thermal sealing can further ensure the tightness of the liner tail 23.

Step 4, sealing the tailing part 232 in the mounting hole 130 by using the bottom cover 14, and then adding a plastic cover (not shown) to the first water inlet 111 of the top cover 110, thereby completing the manufacture of the barreled water dispenser barrel.

The plastic closure can keep the inner container head 22 sanitary during transportation and storage, and is applied only at the end because the inner container head 22 is gradually closely attached to the top cap 110 under the pressure of water during the filling process of step 3, and thus if the plastic closure is applied in step 2 (i.e., before filling), residual air exists between the inner container head 22 and the bung 11 due to the sealing of the plastic closure.

When the water dispenser is used, the plastic cover of the first water inlet 111 is taken out, then the hard outer barrel 1 is inverted as shown in fig. 1, a water barrel is arranged on the existing water dispenser 100 sold in the market, the water guide pipe 101 sequentially penetrates through the first water inlet 111, the third water inlet 224 and the second water inlet 223 to enter the inner cavity of the soft inner container 2 for water taking, and the water guide pipe 101 can break the inner container body 21 between the third water inlet 224 and the second water inlet 223 by using the self gravity of the water barrel in the process of penetrating through the second water inlet 223 so as to enter the inner cavity of the soft inner container 2.

According to the size (namely, the water storage capacity) of the hard outer barrel 1, the liner body 21 can be made of PE (polyethylene) material with the thickness of 0.3-2mm (namely, 0.3, 0.5, 0.8, 1, 1.2, 1.5, 1.8 and 2mm), so that the cost is saved, and the water conduit 101 can be guaranteed to burst the liner body 21.

In the process of taking water, the external air can enter the inner cavity of the hard outer barrel 1 through the air holes 141 of the bottom cover 14 and the space around the sealing device 231, so as to press the soft inner container 2 to deform, thereby preventing the external air from entering the inner cavity of the soft inner container 2 through the water conduit 101 to cause water body pollution. In addition, since the liner tail 23 is kept at the position of the annular boss 132, after the water is used up, the soft liner 2 can be taken out by unscrewing the bottom cover 14, and if the liner head 22 is tightly combined with the barrel opening 11, the top cover 110 can be unscrewed to push the liner head 22 to assist in taking out the soft liner 2.

Since the sealing of the unused soft inner container 2 is performed by the inner container body 21 between the third water inlet 224 and the second water inlet 223, the inner container body 21 between the third water inlet 224 and the second water inlet 223 of the used soft inner container 2 is damaged, and if a person refills the used soft inner container 2 repeatedly, water flows out once the plastic cover of the first water inlet 111 is removed because the passage between the third water inlet 224 and the second water inlet 223 cannot be effectively closed. Thus, it is easy to determine whether the soft inner container 2 is reused.

The biggest difference between the barreled water dispenser barrel and the prior art is that the soft inner container prepared by the method is a disposable product, and the inner container body of the soft inner container cannot be reused. And effectively avoids the problem that the water inlet pipe of the water dispenser is blocked due to the adsorption of the soft inner barrel because the water inlet can generate negative pressure in the prior art.
