Description

Plastic bottle for air mattress {Plastic bottle for air mattress}

The present invention relates to a plastic mat for air mattresses using blow molding, and more particularly, to a plastic mat for air mattresses which can minimize the volume by compressing its internal space when storing or transporting the plastic bottle.

Air mattresses that are used for various purposes are usually composed of a single chamber, and the problem of air mattresses is rocking and sagging, so that the mattress lacks stability, pain caused by sagging and comfortable. I can't sleep. This is due to the fluidity of the air trapped in a single air chamber, which uses several independent air chambers to block the flow of air or to control the flow of air between several air chambers, The emergence of multi-cells and multi-chambers (hereinafter referred to collectively as multi-tubes) has been solved.

As the multitube has a plurality of independent air chambers, there is no communication between the air chambers, so not only the slack or sagging of the air is solved, but the remaining air chambers do not burst at the same time even when a specific air chamber is blown, thus serving as an air mattress. Can be performed continuously. As such, the multi-tube controlling the flow of air is unique because it restricts the air exchange between the air chambers, thereby significantly reducing the transition of shaking, thereby eliminating slack and sagging when used as a bed mattress.

However, despite these advantages, it has been pointed out that in the case of an air mattress having a plurality of air chambers, air must be added and removed for each air chamber, and accordingly, a lot of time is required for air injection and air discharge.

Accordingly, the present applicant has developed an air injection device and an air mattress using the device that can simultaneously fill the air in a plurality of air chambers to solve this problem.

Patent Registration No. 0377326 (multi-cell tube and its manufacturing method), Patent Registration No. 0449994 (multi air mat), Utility Model Registration No. 0305992 (mattress using latex and air tube), patent Registration No. 0510006 (mattress) and Patent Registration No. 0626841 (multi-chamber) relate to an air mattress for simultaneously filling air into a plurality of air chambers as described above. By connecting the above-described air injectors to the inlets in a plurality of arrangement state, it is possible to simultaneously inject and discharge air to the plurality of air chambers through the air injector.

1 is a perspective view showing an air chamber 1 of a representative type embedded in such an air mattress, which is divided into a chamber body 2 and an inlet 3. The chamber body 2 is formed by cutting a film or sheet-like material and heat-sealing several times. The chamber body 2 is simply a double-layered film or sheet in the air chamber 1 and is easily folded. The volume can be reduced.

 Injection port 3 of Figure 1 is made of a hard material. If the material of the injection hole is a soft material with elasticity, such as the chamber body (2), it is not easy to couple the injection hole to the nipple. First, open the end of the soft injection hole with a separate tool and insert the end of the nipple into it. The joining operation becomes very complicated because the tool must be removed from the inlet and the inlet and nipple are combined.

On the contrary, when the injection hole 3 is semi-rigid as shown in FIG. 1, it is possible to make the coupling of the injection hole and the nipple relatively easy since the coupling is made by opposing the hard nipple end and then pushing them. 1, the chamber body 2 is a flexible soft film or sheet, while the injection hole 3 is made of a semi-rigid material.

However, the conventional air chamber 1 has a plurality of fusion portions 2c formed on the side surface 2a, the plane 2b, and the bottom surface (not shown) of the chamber body 2, and thus the chamber body 2 is hermetically sealed. Since the manufacturing process of the chamber body (2) fusion was increased and several parts were heat-sealed. Such a welded portion causes problems such as bursting of the welded portion and its surroundings, air leakage and the like when the conventional air chamber 1 is used for a long time.

In addition, in order to fix the hard injection hole 3 to the soft chamber body 2, the fixed end portion 3a of the injection hole 3 should be fixed by heat-sealing the chamber body 2 so that the work process is added and As a result, there is a problem of an increase in the cost of the product, and in particular, the fusion site of the chamber body 2 and the inlet 3 is a main site where air leakage occurs. .

In order to solve this problem, the present applicant has developed an air chamber for air mattress using blow molding so that the chamber body and the inlet can be integrally formed without fusion.

The air chamber is blow-molded to have a closed space as shown in FIG. 2 and the chamber body 5 in which the entire outer circumferential surface is not fused and blow-molded integrally with the chamber body 5 and the chamber body 5 It consists of an inlet (6) for connecting the space of the outside and is arranged in a plurality of horizontally and connected to the air supply pipe is embedded in the air mattress.

Therefore, the chamber body 5 and the injection port 6 are integrally molded at once without the fusion part by blow molding, so that the air leakage problem of the fusion part is solved, and the manufacturing process is very simple, thereby reducing the product cost. In addition, it is possible to mass-produce with high quality stability, thereby providing excellent products to many people at low cost.

On the other hand, when the air chamber 4 formed by the blow mold is applied to the air chamber 4 in a state in which air is filled after molding, the appearance is deformed to some extent, and when the pressure is removed, the appearance can be restored again. Any material that can be used. As the material of the air chamber 4 that satisfies these conditions, the air chamber 4 may be made of polyethylene (PE) -based material which is mainly used for manufacturing a bucket.

Since the conventional air chamber 4 is made of an inelastic material such as a bucket, it cannot be stored or transported by transforming it into a flat state in a folded form, and must be stored or transported in the same three-dimensional form as it is installed. In addition, since one mattress has several air chambers 4 embedded therein, a relatively large loading space is required for storing or transporting a three-dimensional air mattress as installed.

The problem of the conventional blow-molded air chamber 4, which occupies a large space in storage and transportation, has caused difficulty in distributing the manufactured air chambers 4 to the various parts of the country quickly at low storage and freight costs. It was a factor to increase. Particularly, the problem of the conventional air chamber (4) has become more significant when it comes to overseas exports, which require a lot of storage and freight costs. As a result, they have been a factor in reducing export competitiveness.

This space compression means is composed of a bellows portion 13 formed in the bottle body 11 so that the two corresponding surfaces facing each of the surfaces of the bottle body 11 are folded or unfolded.

The bellows portion 13 is formed around the side of the bottle body 11 so that when the vertical load acts on the installed bottle body 11, it contracts and restores along the vertically pressurized direction.

Plastic bottle using the present blow molding of the present invention is manufactured as follows.

First, in order to manufacture a plastic bottle 10 comprising a bottle body 11 in which a blow molded to have a closed space and the entire outer circumferential surface thereof is unfused, and an injection hole 12 integrally blow molded with the bottle body 11, A blow mold (not shown) including a first mold and a second mold having a shape of a plastic bottle 10 is prepared therein. When the blow mold is prepared, the plastic bottle 10 is formed to prepare a bottle forming tube (not shown) made of inelastic material, and the bottle forming tube is placed between the first mold and the second mold. The ends of the blow pins (not shown) are positioned inside the bottle forming tube. Then, the first mold and the second mold are combined and blown with compressed air into the blow pin to form the plastic bottle 30. In this way, the plastic bottle 10 in which the bottle body 11, the injection hole 12, and the bellows portion 13 are integrally molded is molded.

The plastic bottle 10 manufactured as described above is arranged at regular intervals as shown in FIG. 7 before being embedded in the air mattress, connects the nipples 15, and connects the nipples 15 to the air supply pipe 14.
