Description

Purification container consisting of a single plastic case {CANISTER COMPLETED PLASTIC CASE OF SINGLENESS}

The present invention relates to a gas tank of the gas mask is installed on the gas mask to purify the polluted air from the outside to supply to the inside of the gas mask, the case surrounding the gas mask made of a single body.

In general, the purification tank used to be mounted on the gas mask is formed in the shape of a can, and a filter material such as paper or cloth and a purification material such as carbon are embedded therein to filter and purify the polluted air from the outside to supply the inside of the gas mask.

Therefore, the wearer can inhale the purge air supplied from the septic tank even if the outside air is contaminated, so that the wearer can operate without restriction in the contaminated area.

Referring to the accompanying drawings, with reference to the accompanying drawings, Figure 1 is shown, Figure 1 is a side cross-sectional view of the conventional purification vessel, as shown, the conventional purification vessel, the aluminum or aluminum alloy bonded to each other It consists of a metal hollow case 1 and the cover 2, the hollow case 1 has a mounting portion (1a) is mounted on the gas mask not shown on one side.

At this time, the cylindrical hollow case 1 is integrally coupled to each other as the portion facing the plate-like cover 2 is seamed (S) as shown.

Inside the hollow case 1 and the cover 2, the inner side vent board 12, the inner side nonwoven filter 14, the activated carbon 15, the outer side nonwoven filter 16, the intermediate vent board 18, the filter paper filter ( The filter paper filter case 20 having the 22 is sequentially installed.

Therefore, the outside polluted air flowing in from the cover 2 is purified via the filter paper filter 22, the inner and outer nonwoven filter 16, and the activated carbon 15, and is supplied to the inside of the gas mask through the mounting portion 1a. .

Here, reference numeral H denotes a through hole formed in the inner and intermediate vent plates 12 and 18 and the filter paper filter case 20.

On the other hand, the filter paper filter case 20 is fixed by the inward beading portion 30 formed on the outer circumferential surface of the hollow case 1, the inward beading portion 30 presses the hollow case (1) having a unique characteristic of the metal material It is formed by pressing with.

Therefore, the filter paper filter 22 is firmly fixed to the inside of the hollow case 1 together with the filter paper filter case 20.

However, in the prior art, the purification vessel configured as described above has to carry out a drawing process for making the hollow case 1 of the metal material concave in order to manufacture the finished product, and when the drawing process is completed, an antirust treatment and a painting process for preventing corrosion After the rust and painting is completed, after the rust prevention and painting is completed, the interior of the hollow case (1) and the inward beading unit 30 on the outer circumferential surface of the hollow case (1) Since the beading process to form a) to be carried out in succession, there is a disadvantage that the manufacturing time of the purification tank is considerably delayed.

Of course, the metal cover 2 also needs to be subjected to a drawing process to form the shape.

In addition, since the hollow case 1 and the cover 2 are coupled to each other by the seaming (S), if the purifying container is used for a long time, the bonding force of the seaming (S) is degraded and airtight air cannot be maintained while maintaining the airtight state. There is a disadvantage in that it is introduced immediately or the cover 2 is separated from the hollow case 1.

In addition, despite the heavy weight of the filter medium embedded in the hollow case 1, both the hollow case 1 and the cover 2 are made of a metal material, thereby increasing the weight of the trash can, resulting in inconvenience due to the weight of the gas mask when worn. There is also a disadvantage that the box is generated.

In addition, as the hollow case 1 and the cover 2 are made of aluminum or an aluminum alloy, not only expensive aluminum should be purchased, but also the unit price of the purification tank is increased due to the price of aluminum. Disadvantage is that the supply of aluminum is not easy, and in the case of emergency supply of aluminum can not be produced in a timely purifier can.

The reason why the supply and demand of aluminum is difficult is that most of expensive aluminum is used to produce beverage cans.

However, the biggest drawback of the above is the inner side vent board 12, the inner side nonwoven filter 14, the activated carbon 15, the outer side nonwoven filter 16, the middle ventilating plate 18, and the filter paper inside the hollow case 1. The filter paper filter case 20 having the 22 and the outer vent board 24 are all built in, and only after the cover 2 is combined, the manufacture of the purifier can be completed. 1) After filling the above-described contents inside, after the cover (2) to combine again seaming (S) and inward beading section 30 to work, the manufacturing time is significantly longer.

Thus, while the manufacturing time of the trash can is considerably longer, the gas mask on which the trash can is mounted has a characteristic that it should be supplied in a very limited time in a similar manner, and thus it is impossible to supply the trash can within the limited time with this manufacturing method.

However, if the purification tank is manufactured and loaded in advance, not only the performance of the activated carbon 15 of the purification tank decreases, but also the activated carbon 15 naturally loses its purification function after a certain period of time. impossible.

In addition, when the seaming container made of metal material is crushed, the airtight state is released and the purification ability is lowered. Also, when the crushed part is opened, the activated carbon 15 inside is leaked to the outside. have.

The present invention was created in order to solve the above-mentioned drawbacks, and by injection molding the hollow case and the cover with a plastic material that can be easily supplied, the manufacturing time can be shortened by forming the hollow case and the cover at once. In addition, the object of the present invention is to provide a purifying container made of a lightweight single-piece plastic case due to the characteristics of the plastic material.

As the hollow case and the cover are made of plastic, the joining part can be fused to permanently bond the hollow case and the cover, and the single case of the plastic case can keep the hollow case and the cover completely airtight by fusion. Another object is to provide a cleaning container consisting of.

In addition, such a filter can be prepared in advance by attaching a filter paper filter case with a built-in filter paper to the cover. To provide is another purpose.

In addition, it is possible to prevent the distortion by the self-elasticity to ensure the airtight, there is no fear of corrosion and to provide a trash can that can eliminate the rust and painting operations.

Purification container made of a single-piece plastic case according to the present invention for achieving the above object, the mounting portion (1a) is formed integrally on one side mounted on the gas mask, the hollow case (1) coupled to the cover (2) on the other side The filter paper filter case 20 having an inner ventilating plate 12, an inner side nonwoven filter 14, activated carbon 15, an outer side nonwoven filter 16, an intermediate venting plate 18, and a filter paper filter 22 in the interior thereof. In the purifying container of the gas mask in which the outer side vent board 24 which is selectively employed when necessary is sequentially installed, the hollow case 1 and the cover 2 are formed of a cylindrical lightweight plastic material, but the hollow case 1 On the upper surface of the upper surface and the lower surface of the cover 2, protruding coupling protrusions 101 and coupling grooves 102 into which the coupling protrusions 101 are inserted are formed in the circumferential direction, respectively. The filter paper filter so that the air circulation space is formed in the lower side of the filter paper filter case 20 therein Insert the tooth 20 is spaced apart from the intermediate vent board 18 and fixed with an adhesive, and then ultrasonically fused the coupling portion in the state in which the coupling protrusion 101 and the coupling groove 102 is combined, the hollow case Characterized in that (1) and the cover (2) is configured to form a unitary body.

Hereinafter, with reference to the accompanying drawings illustrating a purifying container made of a unitary plastic case according to the present invention as follows, in the description will be described with the same reference numerals for the components having the same technical idea as the prior art.

Attached Figure 2 is an exploded perspective view of a purifier made of a single-piece plastic case according to the present invention, Figure 3 is a side cross-sectional view of the purifier made of a single-piece plastic case according to the present invention, Figure 4 is a single piece of plastic according to the present invention A perspective view of a purifier made of a case.

As shown, the purifying container made of a single-piece plastic case according to the present invention, the mounting portion (1a) is formed integrally on one side mounted on the gas mask, the hollow case (1) and the cover (2) is integrally coupled to the other side; The inner ventilating plate 12, the inner nonwoven filter 14, the activated carbon 15, the outer nonwoven filter 16, and the intermediate venting plate 18 are sequentially embedded in the hollow case 1 and the cover 2. ), A filter paper filter case 20 having a folded circular filter paper filter 22, and an outer side vent board 24.

Here, the hollow case (1) and the cover (2) is injection molded from a lightweight plastic material, and during injection molding protrudes along the circumferential direction on the upper surface of the hollow case (1) and the lower surface of the cover (2) The coupling protrusion 101 and the coupling groove 102 into which the coupling protrusion 101 is inserted are respectively formed.

And, the inner end of the coupling groove 102 is to be molded in the melt receiving space (102a), so that the melt of the coupling projection 101 that is melted during the ultrasonic oscillation will be described later.

At this time, the melt containing space 102a is a trace amount of the melt of the coupling protrusion 101, for example, it is preferable to have a triangular cross-section as shown, if formed in this triangle, the melt is cured while flowing along the slope.

Of course, since the melt flows along the inclined surface to harden, the attachment area is naturally widened. Accordingly, the adhesive force is strengthened so that the cover 2 and the hollow case 1 are firmly coupled to each other.

As such, since the hollow case 1 and the cover 2 are formed by injection molding, their shape is determined according to the mold shape at the time of molding. As a result, the hollow case 1 and the cover 2 are formed in one container. The drawing process for processing can be excluded.

The hollow case 1 and the cover 2 are coupled to each other by ultrasonic fusion by an ultrasonic oscillator such as a piezo (not shown). When the coupling is described in more detail, first, the cover 2 is disposed on the hollow case 1. Combine the but combine the coupling projection 101 is inserted into the coupling groove (102).

At this time, the coupling protrusion 101 is preferably inserted to the edge of the melt receiving space 102a of the coupling groove 102 as shown in FIG.

And, as shown in FIG. 3, when the coupling protrusion 101 is inserted into the coupling groove 102 and the hollow case 1 and the cover 2 are coupled, the hollow case 1 is turned upside down to ultrasonic waves. Oscillates at the coupling portion of the coupling protrusion 101 and the coupling groove 102.

Then, the surface of the coupling protrusion 101 is melted and fused to each other with the coupling groove 102, and when the ultrasonic wave is stopped, the hollow case 1 and the cover 2 form a unit as shown in FIG. do.

That is, the coupling protrusion 101 acts as a welding base material and melts, and the melt of the coupling protrusion 101 accumulates in the melt receiving space 102a at the inner end of the coupling groove 102 while the coupling groove 102 is melted. It hardens in an attached state inside.

At this time, the melt is cured while spreading evenly to the inner end of the coupling groove 102 along the inclined surface of the triangle-shaped melt receiving space (102a).

Accordingly, the hollow case 1 and the cover 2 are permanently bonded, and the coupling part is maintained in a perfect airtight state due to the melt of the coupling protrusion 101.

Meanwhile, before the hollow case 1 and the cover 2 are unified, the filter paper filter case 20 is inserted into and fixed to the inside of the cover 2.

At this time, the filter paper filter case 20 is attached and fixed to be spaced apart from the intermediate vent board 18 as shown in Figure 3, the lower side of the filter paper filter case 20 before the air introduced from the outside into the activated carbon 15 That is, the air is circulated in the space between the intermediate passage 18 and the filter paper filter case 20 to wait.

Of course, the filter paper filter case 20 attached and fixed to the cover 2 is attached and fixed in a state in which the filter paper filter 22 is accommodated, whereby the outer vent plate 24 between the filter paper filter 22 and the cover 2 is fixed. ) Maintains the state supported by the filter paper filter 22.

However, since the outer side ventilation plate 24 inserted to protect the filter paper filter 22 from the external impact does not influence the performance of the septic tank, it can be configured to exclude the case in the manufacture of the septic tank, the prior art described above In the case of the purifying container by this, this outer side ventilation board 24 is abbreviate | omitted.

The filter paper filter case 20 is fixed to the cover 2 by an adhesive applied to the outer circumferential surface, the adhesive is preferably a silicone or hot melt that generates adhesive strength while curing from a liquid phase to a solid phase.

In addition, when stronger and faster adhesion is required, UV-based adhesives that are cured at high speed by ultraviolet rays are preferable, and 3062-based adhesives that cure most strongly and quickly among UV-based adhesives are preferable.

In the drawings, reference numeral H denotes a through hole formed through the inner, outer and intermediate vent plates 12, 24, and 18, and the filter paper filter cover 20.

Purification container made of a single-piece plastic case of the present invention as described above, when the plastic hollow case 1 and the cover 2 is injection molded, the interior of the hollow case 1 is filled with the filter paper filter case 20 After adhering to the cover (2). When the hollow case 1 and the cover 2 are bonded to each other by fusion with ultrasonic waves, the manufacturing is completed, and thus, there is an advantage in that a large amount of purifier can be manufactured in a short time.

However, the biggest advantage of the present invention is that it is possible to prepare a large amount of the cover (2) to which the filter paper filter case 20 is attached in advance, in this case by preparing a large number of cover (2) in the case of urgent need for a trash can After filling the interior material in (1), the purification case can be manufactured quickly by combining this hollow case 1 with the cover 2 prepared previously.

That is, the hollow case 1 filled with the interior material cannot be prepared in advance due to a problem of deterioration of the activated carbon 15, but the cover 2 having the filter paper filter case 20 can be prepared in advance in large quantities. When filling the interior case in the hollow case (1), only the prepared cover (2) can be combined very quickly to produce a purification container.

Of course, unlike the activated carbon 15, the filter paper filter 22 in the filter paper filter case 20 does not cause a problem in its filtration performance if the humidity is well maintained even after a long time.

Therefore, even when a large order comes in, it is possible to meet the order quantity immediately so that the delivery date can be observed, and the orderer can use the purifying container in a timely manner.

On the other hand, according to the present invention, since the hollow case 1 and the cover 2 are formed of a plastic material having self-elasticity, the cleaner can absorb the shock itself unless it is an extreme shock, thereby preventing the cleaner from being crushed. Can be.

And since there is no fear of corrosion in the characteristic of a material, since the rust prevention work and coating work like a conventional thing can be excluded, manufacturing time can be further shortened.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and the scope of application of the present invention is not limited thereto, and may be appropriately changed within the scope of the same idea.

Therefore, each component and shape, structure, etc. shown in the embodiments of the present invention can be modified and carried out, and such modifications are naturally belonging to the utility model registration claims of the present invention attached.

Purification container made of a single-piece plastic case according to the present invention, since the hollow case and the cover is made of plastic material, the material cost is low, and the supply and demand of materials is easy, so that the desired amount of purifier can be easily produced at any time if necessary. There is.

In addition, as the material cost is low, the unit price of the trash can can be lowered, and ultimately, a gas mask can be produced at a low price, thereby inducing a consumer to purchase a gas mask, thereby increasing the spread of the gas mask.

In addition, since the shape of the hollow case and the cover is molded at a time during the injection molding using the plastic material, the manufacturing time for manufacturing the hollow case and the cover can be shortened, thereby improving the productivity of the septic box according to the reduction of the manufacturing time.

In addition, since the hollow case and the cover of the plastic material are fused and bonded by the ultrasonic wave, the hollow case and the cover are not only permanently bonded, but also the melt solidified as the joining portion of the hollow case and the cover is fused. It also has the effect of sealing the seams between the case and cover perfectly.

In addition, since the filter paper filter case is fixed to the inside of the cover, the filter paper filter can be prevented from flowing and generating noise, and since the air introduced into the circumference of the filtration tank is circulated between the filter paper filter and the intermediate vent, this air There is also an effect to be quickly and easily supplied when the gas mask wearer air inhalation.

Lastly, if the bulk order comes in advance of the preparation of the cover is possible, after filling the hollow case with the interior material, it can be combined with the prepared cover immediately to manufacture the purifier can also supply the purifier in a timely manner.
