The piston part (2A) smoothly moves the piston within the housing part (1A) without using a packing made of soft materials such as silicone, rubber, and resin, and the liquid material filled in the housing part (1A) leaks out. In order to prevent this, it may be preferable that the elongation of the housing portion 1A is greater than the elongation of the piston portion 2A.

From another viewpoint, it may be desirable that the strength of the piston portion 2A is greater than that of the housing portion 1A.

Each part of the syringe-type filling container 10A described above will be described in more detail below with reference to the accompanying drawings.

4 to 7 are views for explaining the housing unit. Hereinafter, descriptions of the parts described above may be omitted.

4 and 5, the housing part 1A may include a first body part 10, an edge part 11, a first head part 12 and an outlet 13.

The first body portion 10 may have a cylindrical shape with both sides open. The inner space of the cylindrical first body 10 may be used as a storage space for storing a liquid material.

The rim 11 may be disposed on the rim of one end of the first body 10. This rim portion 11 may be used to fix the syringe-type filling container 10A to a predetermined jig (Zig, not shown).

As shown in FIG. 5, the first head 12 may include a portion disposed on the other side of the first body 10 and gradually decreasing in diameter.

Here, it may be preferable that the first body portion 10, the rim portion 11 and the first head portion 12 are integrally formed.

The outlet 13 may be formed at the end of the first head 12. This outlet 13 may be a passage through which the liquid material stored in the syringe-type filling container 10A is discharged.

Looking at a cross-section of the edge portion 11 cut along the line A1-A2, as in the case of FIG. 6, the edge portion 11 may include a horizontal peripheral portion 110 and a vertical peripheral portion 111.

The horizontal circumferential portion 110 extends in a horizontal direction (first direction DR1 or second direction DR2) from the edge of one end of the first body portion 10 toward the outside of the first body portion 10. It can have a concentric circle shape.

The vertical periphery 111 extends in a vertical direction (third direction DR3) from the end of the horizontal periphery 110 toward the first head 12 and may have a concentric circle shape. In other words, the vertical peripheral portion 111 may protrude/extend from the front surface (FS) of the horizontal peripheral portion 110 toward the first head portion 12.

Referring to FIG. 7, it can be seen that the horizontal peripheral portion 110 and the vertical peripheral portion 111 have a concentric circle shape.

This rim portion 11 may be used to fix the syringe-type filling container 1A to a jig (not shown). This will be described in more detail below.

8 to 13 are views for explaining the piston part. Hereinafter, descriptions of the parts described above may be omitted.

Referring to FIGS. 8 and 9, the piston part 2A may include a second body part 20, a locking part 21, and a second head part 22.

The second body part 20 may have a cylindrical shape in which both sides are open.

A second opening 23 may be formed at one side of the second body part 20.

The locking part 21 is disposed at one end of the second body part 20, and the diameter R4 may be larger than the diameter R1 of the second body part 20. Accordingly, the locking portion 21 may be caught on one end of the second body portion 20.

The second head portion 22 is disposed on the other side of the second body portion 20 and the end may be blocked.

As shown in FIG. 9, the second head 22 is a connecting part 220, at least one hole 221, an increase part 222, a first reduction part 223, and a second It may include a reduction portion 224.

The connecting portion 220 has a cylindrical shape and may extend from the other end of the second body portion 20. In addition, the diameter R2 of the connection portion 220 may be smaller than the diameter R1 of the second body portion 20.

At least one hole 221 may be formed in a side wall of the connection part 220.

The at least one hole 221 may be connected to the second opening 23.

During the piston movement of the piston part 2A, air in the space between the piston part 2A and the housing part 1A may be discharged to the outside through the at least one hole 221 and the second opening 23. Accordingly, the piston movement of the piston part 2A may be smooth.

The increase portion 222 extends from the end of the connection portion 220 and may include a portion whose diameter gradually increases.

An oblique depression 225 may be formed in the increased portion 222.

The oblique depressed portion 225 is formed on the sidewall of the increase portion 222, is depressed toward the center of the increase portion 222 and may include a portion extending in the oblique direction.

This diagonal depression 225 may enable smooth piston movement of the piston part 2A.

The first reduction portion 223 extends from the end of the increase portion 222 and may include a portion whose diameter decreases by a first ratio.

The second reduction portion 224 may include a portion extending from the end of the first reduction portion 223 and having a diameter decreasing by a second ratio greater than the first ratio. In other words, the slope of the second reduction portion 224 may be greater than the slope of the first reduction portion 223.

The maximum diameter R3 of the second head portion 22, that is, the diameter R3 at the boundary portion between the increase portion 222 and the first decrease portion 223, is the maximum diameter of the second body portion 20 ( May be greater than R1).

Referring to FIG. 10, the second head part 22 may further include a holding part 226 positioned between the first reduction part 223 and the second reduction part 224.

In the holding part 226, the diameter of the second head 22 may be maintained.

The first reduction portion 223 may include a 1-1 reduction portion 223a, a 1-2 reduction portion 223b, and a 1-3th reduction portion 223c.

The ratio at which the diameter of the 1-1 reduction portion 223a decreases is smaller than the ratio at which the diameter of the 1-2 reduction portion 223b decreases, and the ratio at which the diameter of the 1-2 reduction portion 223b decreases May be greater than a rate at which the diameter of the 1-3th reduction portions 223b decreases.

In addition, the width X2 of the 1-2th reduction portion 223b in the vertical direction (the third direction DR3) is the width X1 of the 1-1th reduction portion 223a and the 1-3th reduction portion ( It may be larger than the width X3 of 223c).

In this case, at the boundary between the 1-1 reduction portion 223a and the increase portion 222 and the boundary between the 1-3 reduction portion 223c and the 2-1 reduction portion 224a, the second head ( While the change in the diameter of 22) is relatively gentle, the reduction ratio of the diameter of the first reduction portion 223 can be relatively increased.

The second reduction portion 224 may include a 2-1 reduction portion 224a and a 2-2 reduction portion 224b.

Here, the rate at which the diameter of the 2-1 reduction portion 224a decreases may be smaller than the decrease rate of the diameter of the 2-2 decrease portion 224b.

In addition, the width X5 of the 2-2nd reduction portion 224b in the vertical direction (the third direction DR3) may be larger than the width X4 of the 2-1th reduction portion 224a.

In this case, while relatively gentle change in the diameter of the second head 22 at the boundary between the 1-3th reduction portion 223c and the 2-1th reduction portion 224a, the second reduction portion 224 ), the reduction ratio of the diameter can be made larger.

Referring to FIG. 11, the maximum diameter R3 of the second head portion 22 of the piston portion 2A of (B) is the diameter of the first body portion 10 of the housing portion 1A of (A) (maximum Diameter) (R5).

From another viewpoint, the diameter R3 at the boundary between the increase portion 222 and the first decrease portion 223 may be larger than the diameter R5 of the first body portion 10.

In addition, the maximum diameter R3 of the second head portion 22 may be larger than the inner diameter R5a of the first body portion 10.

In addition, the wall thickness of the first body portion 10 may be sufficiently thin. Preferably, as shown in FIG. 12, the wall thickness t1 of the first body portion 10 may be thinner than the wall thickness t2 of the second body portion 20.

In this way, when the wall thickness t1 of the first body portion 10 is sufficiently thin and the elongation of the housing portion 1A is relatively large, the second head portion 22 of the piston portion 2A becomes the housing portion ( The piston movement may be performed in a state in close contact with the first body portion 10 within the first body portion 10 of 1A).

For example, as shown in FIG. 13, when the piston part 2A is inserted into the first body part 10 of the housing part 1A, the second head part 22 of the piston part 2A becomes the first body part. By pushing up the side wall of (10), a part of the first body portion 10 may rise convexly.

Thereafter, when the piston part 2A is separated from the first body part 10 or moves to a different position within the first body part 10, the raised part may be restored again.

In this way, when the second head portion 22 is in close contact with the first body portion 10, the gap between the first body portion 10 and the second head portion 22 without using a packing made of a soft material such as silicon It can prevent leakage of liquid materials.

In addition, the second head 22 may effectively push up the liquid material stored in the first body 10 and discharge it through the discharge port 13.

14 to 17 are views for explaining the closure portion. Hereinafter, descriptions of the parts described above may be omitted.

Referring to FIGS. 14 and 15, the stopper 3A may include a third body part 30 and a supporting plate 31.

The third body part 30 may have a cylindrical shape with one side open. In other words, a third opening 32 may be provided at one side of the third body part 30.

At least a portion of the end of the housing 1A, that is, the first head 12 may be inserted into the third opening 32.

The support plate 31 may block the other end of the third body part 30. This support plate 31 may have a substantially circular plate shape.

15 and 16, the support plate 31 may include a depression 33 and a protrusion 34. 16 is a cross-sectional view of the support plate 31 cut along the line A3-A4.

The recessed portion 33 is formed on the outer surface (OS) of the support plate 31 and may be recessed toward the third body portion 30. Here, the outer surface (OS) of the support plate 31 means a surface facing the outside from the support plate 31, and the inner surface (IS) is a surface facing the third body part 30 from the support plate 31 Can mean

The depression 33 may include a portion having a parabolic cross section.

The protrusion 34 is formed on the inner surface (IS) of the support plate 31 and may protrude toward the third body part 30.

These protrusions 34 may be located inside the third body 30 and correspond to the outlet 13 of the housing 1A. For example, in a state in which the housing portion 1A and the cap portion 3A are coupled, the protrusion 34 may be fitted into the outlet 13 to close the outlet 13.

Here, the width (or diameter) R7 of the support plate 31 in the horizontal direction (the first direction DR1 or the second direction DR2) may be larger than the diameter R6 of the third body part 30. have.

In this way, when the support plate 31 has a sufficiently large width and a large area and includes the depression 33, the syringe-type filling container 10A can be easily erected.

For example, as shown in Fig. 17A, a syringe-type filling container 10A can be erected with the stopper 3A as a support. Here, by the support plate 31, the syringe-type filling container 10A can maintain a stable posture.

If the support plate 31 does not include the depression 33, as shown in Fig. 17B, if a foreign material is located under the support plate 31 or the bottom is uneven, syringe-type filling Container 10A may be difficult to balance.

The material of the syringe-type filling container 10A described above will be described below.

As described above, the maximum diameter R3 of the second head portion 22 is larger than the maximum diameter R5 of the first body portion 10, and the second head portion 22 is the first body portion 10 In order to make the piston motion in close contact with ), the housing 1A needs to have sufficient elasticity.

As such, the housing part 1A may include a low-density polyethylene (LDPE) material to have sufficient elasticity.

Such low-density polyethylene (LDPE) is a synthetic resin made of ethylene and may have water resistance, chemical resistance, and electrical insulation.

In addition, in order to allow the second head 22 to smoothly perform the piston movement within the first body 10, the housing 1A may include a slip agent.

In this case, by reducing the coefficient of friction between the first body portion 10 and the second head portion 22, the sliding of the surface may be sufficiently implemented.

In other words, the slip agent may serve as a lubricant between the first body portion 10 and the second head portion 22.

Examples of slip agents that can be used for the housing 1A include K-5060N, ARMOSLIP series, Oleamide, and Erucamide.

If the content of the slip agent in the housing portion 1A is excessively low or not, the piston movement may not be smooth due to friction occurring between the first body portion 10 and the second head portion 22.

On the other hand, when the content of the slip agent in the housing part 1A is excessively large, the coefficient of friction between the first body part 10 and the second head part 22 can be sufficiently reduced, but the housing part 1A The manufacturing cost can rise excessively.

In consideration of this, it may be preferable that the content of the low-density polyethylene (LDPE) in the housing 1A is 99 to 99.98 parts by weight, and the content of the slip agent is 1 to 0.02 parts by weight.

In addition, it may be more preferable that the housing unit 1A includes 99.5 to 99.96 parts by weight of low-density polyethylene and 0.5 to 0.04 parts by weight of the slip agent.

On the other hand, the piston part 2A prevents the liquid material from leaking through the gap between the first body part 10 and the second head part 22 while performing a piston movement within the housing part 1A, and the housing part ( It may be desirable to have a relatively high strength in order to effectively discharge the liquid material stored inside 1A).

To this end, the piston part 2A may include a polypropylene (PP) material. Polypropylene is one of thermoplastic general purpose resins and can have heat resistance and chemical resistance.

It may be preferable that the piston part 2A further includes a glass material in order to improve strength and improve resistance to chemicals such as acid.

When the piston part 2A includes a glass material together with a polypropylene (PP) material, the second head of the piston part 2A is made of a liquid material that is filled in the storage space inside the housing part 1A. 22) can prevent damage.

In addition, in order for the second head 22 to smoothly perform the piston movement within the first body 10, the piston 2A may also include a slip agent like the housing 1A. .

Examples of slip agents that can be used for the piston part 2A include K-5060N, ARMOSLIP series, Oleamide, and Erucamide.

If the content of the slip agent in the piston part 2A is excessively small or not, the piston movement may not be smooth due to friction occurring between the first body part 10 and the second head part 22.

On the other hand, when the content of the slip agent in the piston part 2A is excessively large, the manufacturing cost of the piston part 2A may be excessively increased.

In addition, if the content of the glass material in the piston portion 2A is excessively small or if the content of the glass material is excessively small, the resistance of the piston portion 2A to chemicals may be excessively weakened, and the strength of the piston portion 2A may be excessively weakened.

On the other hand, when the content of the glass material in the piston part 2A is excessively large, the formability may be deteriorated and the manufacturing cost may be excessively increased.

Considering the above, the content of polypropylene (PP) in the piston 2A is 94 to 95 parts by weight, the content of the slip agent is 1 to 0.02 parts by weight, and the content of the glass material is 4 to 5.92 parts by weight. It may be desirable.

More preferably, the piston part 2A may include 94.5 to 94.98 parts by weight of polypropylene (PP), 0.5 to 0.04 parts by weight of a slip agent, and 4.52 to 5.46 parts by weight of a glass material.

If the housing portion 1A and the piston portion 2A are manufactured in the composition ratio as described above, it may be easier to increase the elongation rate of the housing portion 1A than that of the piston portion 2A.

In addition, when the wall thickness t1 of the first body portion 10 of the housing portion 1A is thinner than the wall thickness t2 of the second body portion 20 of the piston portion 2A, the first body portion (10) The second head part 22 can perform the piston movement more effectively within.

An embodiment of the syringe-type filling container 10A described above will be described below.

[First Example]

It can be seen that.

The reason why the evaluation of the piston motion in Comparative Example 1 and Comparative Example 2 is poor is that the content of the slip agent is excessively low, and the friction coefficient between the first body portion 10 and the second head portion 22 is excessively high. I can.

In the housing portion 1A of the syringe-type filling container 10A according to Comparative Example 3 containing 90 parts by weight of low-density polyethylene (LDPE) and 10 parts by weight of a slip agent, the evaluation of the elongation and the evaluation of the piston motion were good, It can be seen that the evaluation on the aspect of manufacturing cost is poor.

This may be a problem caused by an excessive increase in the total cost of the syringe-type filling container 10A.

In addition, although not shown in Table 1, when the content of the slip agent is excessive, properties such as elongation of the housing 1A may be deteriorated due to the properties of the slip agent.

The reason why the evaluation of the elongation rate in Comparative Examples 4 and 5 is poor or normal may be that the strength of the piston part 2A is not sufficiently strong because the content of the glass material in the piston part 2A is excessively small or absent. .

In addition, the reason why the evaluation of resistance in Comparative Examples 4 and 5 is poor or normal is that the surface of the piston 2A is a weakly acidic chemical solution because the content of the glass material in the piston 2A is excessively small or absent. This may be due to damage such as being corroded by.

The reason for the poor evaluation of the formability in Comparative Example 7 may be because the content of the glass material is excessively large in the piston part 2A, so that an excessively long time is required to melt the powder material, and the time required for melting is excessively long have.

In addition, the reason for the poor evaluation of the manufacturing cost in Comparative Example 7 is that the content of the glass material in the piston part 2A was excessive, and the total manufacturing cost of the piston part 2A was increased due to the relatively expensive glass material. It could be because.

On the other hand, in the piston part 2A of the syringe-type filling container 10A according to Comparative Example 7 containing 94.95 parts by weight of polypropylene (PP), 0.05 parts by weight of a slip agent, and 5 parts by weight of a glass material, evaluation of elongation, It can be seen that the evaluation of resistance, piston motion, formability, and manufacturing cost were all good.
