Description

  The present invention relates to a cosmetic container for applying a cosmetic to an application portion.

  Conventionally, in a cosmetic container in which liquid cosmetics such as liquid cosmetics in a container are sent to an application part through a flow path for application, a part of the cosmetic has poor fluidity When the coating material is used, the flow channel (including the discharge port) may be clogged by the poorly fluid cosmetic material, which may hinder the application.

  Therefore, in Patent Document 1 below, for example, in a liquid ejector that injects liquid such as liquid cosmetics, there is a technique for preventing clogging due to solidification of the residual liquid by sucking back the liquid remaining in the nozzle. It is disclosed.

Japanese Patent No. 4236748

  However, in the above-mentioned Patent Document 1, when the liquid is solidified, it cannot be sucked back and clogging occurs.

  Therefore, an object of the present invention is to provide a cosmetic container that can prevent clogging due to cosmetics with poor fluidity and enables good application with cosmetics with good fluidity.

A cosmetic container according to the present invention includes a container body including a storage chamber capable of storing a fluid cosmetic, an application unit for applying the fluid cosmetic, and a fluid cosmetic of the storage chamber. A guide cylinder for guiding the liquid to the application section , the guide cylinder having a flat surface on the application section side, an opening communicating with the storage chamber, and a fluid makeup flowing from the opening fee, a flow path to flow towards the axially applied portion side of the guide tube, located in the center of the application portion of the guide tube, blocked the flow to close the application unit side of the flow path, the inner surface coating portion It has a damming portion configured in a concave shape on the side, and a guide port that is opened at a position closer to the opening portion than the damming portion of the flow path and is connected to a region communicating with the application portion.

  According to such a cosmetic container, the cosmetic material having fluidity in the storage chamber flows into the guide tube through the opening of the guide tube and flows through the flow path in the guide tube. Cosmetics with poor fluidity are dammed up and stored by a damming part that closes the application part side of the flow path of the guide tube. On the other hand, the cosmetics with good fluidity are separated from the cosmetics with poor fluidity stored in the damming part, and flow into the guide port opened to the position on the opening side from the damming part of the flow path, It flows to the area | region connected to an application part, and is sent to an application part. Thus, it is possible to prevent cosmetics with poor fluidity from being sent to the application part, prevent clogging with cosmetics with poor fluidity, and send cosmetics with good fluidity to the application part. Good application with a cosmetic material having good fluidity can be performed.

Here, since the damming portion is configured to have a concave shape on the application portion side, cosmetics with poor fluidity are suitably stored in the damming portion.

  In addition, if the size of the guide port is smaller than the opening of the concave damming portion, the cosmetic with poor fluidity is selectively dammed according to the difference in the size of the opening of the guide port and the concave damming portion. The cosmetics that are blocked by the part and have good fluidity selectively flow into the guide port.

  Further, among the damming portion and the flow channel sandwiching the induction port therebetween, the inner surface position on the induction port side of the damming portion is located on the radially outer side from the inner surface position on the induction port side of the flow channel, Cosmetics with poor fluidity are unlikely to flow into the induction port, and are more preferably blocked by the damming unit, and cosmetics with good fluidity flow into the induction port more suitably, thus Separation between bad cosmetics and good cosmetics is further improved.

  Here, when air accumulates inside the damming portion, it is prevented that cosmetics having poor fluidity are accumulated in the damming portion. Therefore, it is preferable that the damming portion has an air hole that connects the inner side thereof and a region located on the outer side and communicating with the application portion. When such a structure is adopted, the air that is about to accumulate inside the damming part is released through the air holes to the area that is located outside the damming part and communicates with the application part, and has poor fluidity. Can be suitably stored in the damming portion.

  As described above, according to the present invention, it is possible to prevent clogging due to cosmetics having poor fluidity, and it is possible to perform good application using cosmetics having good fluidity.

FIG. 13 shows a fifth embodiment of the present invention, FIGS. 14 to 16 show a sixth embodiment of the present invention, and FIGS. 17 and 18 show a seventh embodiment of the present invention. It is shown.

  First, a first embodiment shown in FIGS. 1 to 9 will be described. 1 and 2 are external views of the cosmetic container according to the first embodiment, FIGS. 3 and 4 are cross-sectional views of FIGS. 1 and 2, and FIG. 5 is a longitudinal section showing a leading tube and a guide tube. FIG. 6 to FIG. 9 are each a diagram showing a guide tube, and the cosmetic container of this embodiment is used when applying a cosmetic material having fluidity to an application portion. Examples of fluid cosmetics include liquid cosmetics such as cosmetic liquids, cleaning liquids, mascara, anti-aging, nail care solutions, hair cosmetics, and fluids such as gels and kneads. Can be used.

  As shown in FIGS. 1 to 4, the cosmetic container 100 is rotatably connected to a main body cylinder (container main body) 1 including a storage chamber 1 a for storing cosmetics having fluidity and a rear portion of the main body cylinder 1. The outer cylinder includes an operation cylinder 2, a guide cylinder 3 connected to the distal end portion of the main body cylinder 1, and a front cylinder 4 connected to the distal end side of the guide cylinder 3 and having an application portion 4a at the distal end. When the user rotates the operation cylinder 2 in one direction (feeding direction) with respect to the main body cylinder 1, the screwing mechanism 5 and the anti-rotation mechanism 6 as an extrusion mechanism configured in the container and rotation in one direction are allowed. According to the ratchet mechanism 7, the piston 8 disposed in the storage chamber 1 a is sequentially drawn out toward the distal end side (applying portion 4 a side) of the main body cylinder 1, and cosmetics having fluidity in the storage chamber 1 a are supplied to the main body cylinder 1. It is set as the structure extruded sequentially toward the front end side. Note that the push-out mechanism may be configured such that the piston 8 can move forward / backward without the ratchet mechanism. Further, a cap that is detachably attached to the distal end portion of the main body cylinder 1 and covers the application portion 4a is omitted here.

  Next, the guide tube 3 and the front tube 4 that are the features of the present embodiment connected to the tip of the main body tube 1 will be described.

  The guide tube 3 is for guiding the cosmetic material having fluidity in the storage chamber 1a to the application part 4a of the front tube 4, and is formed of, for example, polyethylene, polypropylene, or other plastic materials. The guide tube 3 is attached to the main body tube 1 and the holder portion 3a to which the leading tube 4 is attached, and as shown in FIGS. 6 to 9, the guide portion is connected to the holder portion 3a and extends toward the distal end side. 3b.

  The holder portion 3a has a substantially bottomed cylindrical shape and includes a flange portion 3c at the rear end. The flange 3c is provided with an annular recess 3d for engaging with the annular projection 1d at the tip of the main body cylinder 1 in the axial direction. In addition, on the outer peripheral surface above the flange portion 3c of the holder portion 3a, two protrusions 3e and 3e are provided on the half circumference side of the cylinder so as to enter and engage with the concave portion of the front tube 4. The two protrusions 3e and 3e are also provided on the opposite side across the axis. The bottom portion 3f of the holder portion 3a serves as a lid of the storage chamber 1a of the main body cylinder 1, and has a shape that is recessed in a generally bowl shape toward the distal end side so that the rear end side becomes wider. An opening 3g communicating with the storage chamber 1a is opened in the substantially bowl-shaped bottom 3f. The opening portion 3g is a long hole extending in one direction so as to exhibit a cross-sectional shape passing through the axis of the holder portion 3a (see FIG. 7), and guides cosmetics having fluidity in the storage chamber 1a. It is for leading to 3b.

  The guide portion 3b is erected at a position around the opening 3g on the front end side surface of the holder portion 3a. The guiding portion 3b has a shape obtained by rounding the end portion on the long diameter side of a flat, substantially rectangular tube shape (hereinafter referred to as a flat tube shape), and its top portion is closed. And the guidance | induction part 3b is provided so that the flat cylindrical hole may overlap and communicate with the long hole-shaped opening part 3g of the holder part 3a in an axial direction. While the outer peripheral surface of the guide portion 3b and the inner peripheral surface of the holder portion 3a are connected and integrated with each other at the long diameter portion of the guide portion 3b (see FIGS. 3 and 6), A space S1 is formed between the outer peripheral surface of the guide portion 3b and the inner peripheral surface of the holder portion 3a (see FIGS. 4 and 6).

  The flat cylindrical hole of the guide portion 3b constitutes a flow path 3h that allows the flowable cosmetic material flowing in from the opening 3g to flow toward the application portion 4a side, which is the distal end side in the axial direction of the guide tube 3. The inner surface of the guiding portion 3b constituting the flow path 3h is an inclined surface whose long diameter side gradually tapers (the facing inner surfaces approach each other) as it goes from the middle in the axial direction toward the tip side, and its tip The application part 4a side which is the side is closed by the top part. And the front end side of the flow path 3h containing this top part presents the concave shape dented to the application part 4a side, and this concave shape becomes the damming part 3i which dams the flow of the cosmetics which have fluidity ( Details will be described later).

  In the flow path 3h, at the position on the opening 3g side of the damming portion 3i and spaced apart in the major axis direction, the guide ports 3j and 3j opened in the direction orthogonal to the axial direction of the guide portion 3b are opposed. It is provided as follows. The guide port 3j is provided over the entire width (the entire short axis direction) of the flow path 3h (see FIG. 9). The guide port 3j communicates with a guide path 3k toward the tip side, and the guide path 3k is an inclined port in which the opening on the long diameter side gradually widens toward the tip side. The guide path 3k passes through the top of the guide portion 3b and communicates with the inside of the front tube 4.

  Here, as shown in FIG. 8, the size of the guide port 3j is made smaller than the opening of the concave damming portion 3i. Here, the inner surface position P on the guide port 3j side of the flow path 3h is the inner surface position on the guide port 3j side of the flow path 3h among the dam part 3i and the flow path 3h sandwiching the guide port 3j therebetween. It is located radially inward from Q. This is because, at the time of injection molding of the guide cylinder 3, a die having a portion corresponding to the guide path 3k on the tip side mold and an inner portion (on the opening 3g side) of the damming portion 3i on the back end side die. This is to prevent the mold from being overwhelmed when the mold having the portion corresponding to the part 3) and the part corresponding to the flow path 3h is released in the direction away from each other. And the induction | guidance | derivation opening 3j shape | molded by such a mating surface (contact surface) of both metal mold | dies will be opened toward the direction orthogonal to the axial direction of the guidance | induction part 3b.

  The front tube 4 is made of, for example, a soft elastic material such as elastomer or silicon rubber, and has an outer tube portion 4b and an inner tube portion 4c as shown in FIG. The outer cylinder portion 4b has a rear portion, specifically, an insertion portion 4d inserted into the distal end portion of the main body cylinder 1, and is configured in a cylindrical shape. As shown in FIG. 2, more specifically, the front tube 4 has a shape that is long in one direction (vertical direction in FIG. 2) and short in a direction orthogonal to the one direction (vertical direction in FIG. 1). The tip of each of the two is gradually narrowed so as to have a shape obtained by rounding the end portion on the long diameter side of a substantially rectangular shape. On the inner peripheral surface of the insertion portion 4d, a recess is provided for the protrusion 3e of the holder portion 3a of the guide tube 3 to enter and engage (in FIG. 3 and FIG. 4, it is hidden from the cross section and cannot be seen). .

  As shown in FIGS. 3 and 4, the inner cylinder portion 4 c has a flat cylindrical shape for inserting the flat cylindrical guide portion 3 b and extends to the distal end side. As shown in FIG. 3, the inner cylinder portion 4 c and the outer cylinder portion 4 b are connected and integrated at the long diameter portion of the guide portion 3 b, while the portions other than the long diameter portion are shown in FIG. 4. In addition, a space S2 communicating with the space S1 of the guide tube 3 is provided. The space S2 extends to the distal end side and is closed at the distal end where the outer cylindrical portion 4b and the inner cylindrical portion 4c merge. This space S2 is intended to prevent the occurrence of sink marks (including voids) during injection molding by making the thickness of the front tube 4 uniform.

  As shown in FIG. 3, the flat cylindrical hole of the inner cylinder portion 4 c is coated with a cosmetic material having fluidity flowing out through the flow path 3 h, the guide port 3 j, and the guide path 3 k of the guide cylinder 3 in the axial direction. The flow path 4e for flowing toward the part 4a side and leading to the application part 4a is configured. That is, the flow path 4e constitutes a region communicating with the application part 4a, and the guide port 3j of the guide tube 3 is connected to this region.

  A flat discharge port 4f having the same shape as that of the flow path 4e communicates with the flow path 4e so as to overlap the flow path 4e at the distal end portion of the front cylinder 4 where the outer cylinder portion 4b and the inner cylinder portion 4c merge. Opened. Around the flat discharge port 4f, a projection group 4h is provided integrally with the front tube 4, and the discharge port 4f and the projection group 4h constitute an application portion 4a.

  The application portion 4a is not limited to the projection group, and may be, for example, a brush or the like. Furthermore, the application unit 4a may be a simple application surface having only the discharge port without the projection group and the brush. good.

  Then, as shown in FIG. 5, the front tube 4 is extrapolated to the guide tube 3, and the rear end surface of the insertion portion 4 d hits the front end surface of the flange portion 3 c of the guide tube 3 and is guided to the recess of the front tube 4. When the protrusion 3e (see FIGS. 6 and 7) of the holder portion 3a of the tube 3 enters and engages, the guide tube 3 is mounted so as not to rotate and to move in the axial direction, and is integrated.

  As shown in FIGS. 3 and 4, the front tube 4 and the guide tube 3 integrated as described above are inserted into the main body tube 1, and the step portion 4 g of the front tube 4 is placed on the front end surface of the main body tube 1. The concave portion 3d of the guide tube 3 is engaged with the convex portion 1d of the main body tube 1 in the axial direction so that the main body tube 1 is mounted so as not to move in the axial direction.

  According to the cosmetic container 100 configured in this way, the piston 8 moves forward in accordance with the rotation operation of the main body cylinder 1 and the operation cylinder 2 by the user, and the cosmetic having fluidity is pushed out from the storage chamber 1a. The charge flows into the guide tube 3 through the opening 3g of the guide tube 3 and flows through the flow path 3h.

  Here, when a part of cosmetics having fluidity becomes cosmetics with poor fluidity, they are dammed up and stored by a damming part 3i located on the application part 4a side from the guide port 3j. On the other hand, cosmetics with good fluidity are separated from cosmetics with poor fluidity stored in the damming portion 3i, flow into the guide port 3j, flow through the guide path 3k, and flow into the front tube 4. The flowable cosmetic material that has flowed out flows through the flow path 4e of the front tube 4, discharges from the discharge port 4f, and is applied to the protrusion group 4h.

  As described above, in the present embodiment, the blocking unit 3i can prevent the poorly fluid cosmetic from being sent to the application unit 4a, can prevent clogging by the poorly fluid cosmetic, and can prevent fluidity. Good cosmetics can be sent to the application part 4a, and the good application | coating with the said fluid good cosmetics can be performed.

  Moreover, in this embodiment, since the damming part 3i is comprised by the application part 4a side and is dented, it can accumulate | store the cosmetics with bad fluidity | liquidity in the said damming part 3i suitably.

  Further, since the size of the guide port 3j is smaller than the opening of the concave damming portion 3i, a cosmetic with poor fluidity is selected according to the difference in the size of the opening of the guide port 3j and the concave damming portion 3i. Thus, the damming portion 3i can be dammed, and the cosmetic material having good fluidity can be selectively introduced into the guide port 3j.

  FIG. 10 is a longitudinal sectional view showing a leading tube and a guide tube of a cosmetic container according to the second embodiment of the present invention. In the following embodiments including the second embodiment, the same elements or the same functions as those of the other embodiments are denoted by the same reference numerals, and redundant description is omitted.

  The second embodiment is different from the first embodiment in that instead of the guide tube 3, the flow path 3 h of the guide portion 3 b is extended to the tip side, and the damming portion 3 i protrudes into the flow path 4 e of the front tube 4. This is a point using the guide tube 13.

  In the guide tube 13, the guide port 3 j is opened at a portion protruding into the flow path 4 e of the front tube 4. In this manner, the guide port 3j is opened at a portion protruding into the flow path 4e of the front tube 4, and thus is configured to be directly connected to the flow path 4e of the front tube 4.

  Such a second embodiment also has the advantage that the guiding path 3k of the first embodiment can be dispensed with in addition to obtaining substantially the same effect as the first embodiment. In addition, the guide cylinder 13 is a die having a portion corresponding to an outer portion of the damming portion 3i (a portion on the application portion 4a side) on the tip side, and a damming portion 3i on the rear end side die. The guide port 3j is molded by separately using a pin-shaped mold that extends in a direction perpendicular to the axial direction.

  FIG. 11 is a longitudinal sectional view showing a leading tube and a guide tube of a cosmetic container according to the third embodiment of the present invention.

  The third embodiment differs from the first embodiment in that instead of the guide tube 3, a guide tube 14 having another guide path 14k and having no guide path 3k of the first embodiment is used.

  The guide path 14k includes a first guide path 14m and a second guide path 14n.

  The first guide path 14m communicates with the guide port 3j and extends in a direction orthogonal to the axial direction and is opened on the outer peripheral surface of the guide portion 3b.

  The second guide path 14n is recessed in the outer peripheral surface of the guide portion 3b and extends in the axial direction. One end of the second guide path 14n communicates with the first guide path 14m, and the other end has a groove 14p opened in the flow path 4e. By providing, it forms between the said groove | channel 14p and the internal peripheral surface of the front cylinder 4 which faces this groove | channel 14p. Here, the groove 14p is a groove having a cross-sectional shape such as a rectangular cross section or a substantially semicircular cross section.

  Also in the third embodiment, cosmetics with poor fluidity are blocked by the blocking unit 3i, and cosmetics with good fluidity flow into the flow path 4e through the guide port 3j and the guide path 14k. Thus, it can be sent to the application unit 4a, and the same effect as in the first embodiment can be obtained. The guide cylinder 14 has a die having a portion corresponding to the groove 14p on the front end side mold, and a portion corresponding to the inner portion of the damming portion 3i and the flow path 3h on the rear end side die. The guide port 3j and the first guide path 14m are formed by separately using a pin-shaped mold that extends long in a direction orthogonal to the axial direction.

  FIG. 12 is a longitudinal sectional view showing a leading tube and a guide tube of a cosmetic container according to the fourth embodiment of the present invention.

  The fourth embodiment is different from the third embodiment in that a guide tube 15 having no groove 14p is used instead of the guide tube 14, and the groove 14p is moved from the guide tube 14 instead of the front tube 4. The point is that the front tube 24 is used.

  Here, the groove 14p of the front tube 24 is configured such that one end thereof communicates with the first guide path 14m and the other end is opened to the flow path 4e, and the guide tube 15 facing the groove 14p and the groove 14p. A second guide path 24n is formed between the guide section 3b and the outer peripheral surface of the guide section 3b. The first guide path 14m and the second guide path 24n constitute a guide path 24k.

  Also in the fourth embodiment, cosmetics with poor fluidity are blocked by the blocking unit 3i, and cosmetics with good fluidity flow into the flow path 4e through the guide port 3j and the guide path 24k. Thus, it can be sent to the application part 4a, and the same effect as in the third embodiment can be obtained. The guide cylinder 15 is formed by using a die having a tip side die and a die having a rear end side die and an inner portion of the damming portion 3i and a portion corresponding to the flow path 3h. The first guide path 14m is formed by separately using a pin-shaped mold extending long in a direction orthogonal to the axial direction.

  FIG. 13 is a longitudinal sectional view showing a leading tube and a guide tube of a cosmetic container according to a fifth embodiment of the present invention.

  The fifth embodiment is different from the first embodiment in that a guide cylinder 16 further having a damming portion 16i is used instead of the guide cylinder 3.

  In this guide cylinder 16, the inner surface of the guide portion 3b constituting the flow path 3h (more precisely, the inner surface on the opening portion 3g side of the guide port 3j) is bent toward the tip side, so that the position outside the guide path 3k. That is, concave damming portions 16i, 16i are provided on both sides of the damming portion 3i.

  In the fifth embodiment as well, in addition to being able to obtain substantially the same effect as in the first embodiment, it is possible to dam up and store cosmetics having poor fluidity in the damming portions 16i and 16i. Therefore, it is possible to further prevent clogging due to cosmetics with poor fluidity and to perform better application with cosmetics with good fluidity. The guide cylinder 16 has a die having a portion corresponding to the guide path 3k in the tip side mold, and a portion corresponding to the inner portion of the damming portion 3i and the flow path 3h in the rear end side die. Molding can be performed by using a mold and releasing both molds in directions away from each other.

  Here, in the first and fifth embodiments, as described above, only the front end side and rear end side molds are used during molding so as not to be forcibly removed. As a specific configuration, the inner surface position P on the guide port 3j side of the damming portion 3i of the damming portion 3i and the flow channel 3h sandwiching the guide port 3j therebetween is set on the guide port 3j side of the flow channel 3h. In the sixth embodiment, the inner surface position P on the guide port 3j side of the damming portion 3i is flowed without forcibly removing the mold in the sixth embodiment. The path 3h is positioned radially outward from the inner surface position Q on the guide port 3j side.

  14 is a perspective view of the guide tube of the cosmetic container according to the sixth embodiment of the present invention as seen obliquely from above, FIG. 15 is a longitudinal sectional view of the guide tube shown in FIG. 14, and FIG. It is a longitudinal cross-sectional view of the orthogonal direction.

  The sixth embodiment is different from the first embodiment in that the guide tube 3 is replaced with a two-part guide tube 17.

  The guide tube 17 includes a lid portion 17a having a ceiling-like flat tube shape in which the guide portion 3b includes a top portion including a damming portion 3i, and a portion closer to the opening 3g, specifically, a flow path 3h. The flat cylindrical portion 17b including the guide port 3j, the guide path 3k, and the like is divided, and the flat cylindrical portion 17b covers the lid portion 17a.

  The lid portion 17a has an outlet port 17k that communicates with the guide path 3k of the flat cylindrical portion 17b so as to overlap in the axial direction.

  In the flat cylindrical portion 17b, the portion on the guide port 3j side of the flow path 3h is a protruding portion 3r that protrudes from the guide port 3j toward the axis of the flat cylindrical portion 17b. The protrusion 3r is bent so that the tip is further toward the tip. Thus, in the sixth embodiment, the inner surface position P on the guide port 3j side of the damming portion 3i is located on the radially outer side from the inner surface position Q on the guide port 3j side of the flow path 3h. Then, by covering the flat cylindrical portion 17b with the lid portion 17a, the guide port 3j is formed between the end portion of the damming portion 3i of the lid portion 17a and the protruding portion 3r of the flat cylindrical portion 17b.

  In the sixth embodiment as well, in addition to being able to obtain substantially the same effect as the first embodiment, the inner surface position P on the guide port 3j side of the damming portion 3i is the guide port of the flow path 3h. Since it is located radially outward from the inner surface position Q on the 3j side, cosmetics with poor fluidity are unlikely to flow into the guide port 3j, and can be more suitably dammed by the damming portion 3i, and also have fluidity. The cosmetics with good quality can be flowed into the guide port 3j more suitably, and as a result, the separability between the cosmetics with poor fluidity and the good cosmetics can be further enhanced. In addition, in this embodiment, since the tip of the protruding portion 3r is bent toward the tip side, the cosmetic material with poor fluidity is less likely to flow into the guide port 3j, and the cosmetic material with poor fluidity is used. And the separation of good cosmetics can be further enhanced.

  Even in the positional relationship of P and Q, the guide part 3b of the guide cylinder 17 is divided into two parts, a lid part 17a and a flat cylindrical part 17b. It is designed not to skip.

  FIG. 17 is a perspective view of the guide tube of the cosmetic container according to the seventh embodiment of the present invention as viewed obliquely from above, and FIG. 18 is a longitudinal sectional view of the guide tube shown in FIG.

  The seventh embodiment is different from the first embodiment in that the damming portion 3i is located on the inner side (opening portion 3g side) and on the outer side (application portion 4a side) and communicates with the application portion 4a. This is the point that an air hole 3t that connects a certain flow path 4e is provided.

  Here, the air hole 3t is a small-diameter air hole, and is set to a size that prevents cosmetics having poor fluidity from passing through the air hole 3t.

  In the seventh embodiment as well, in addition to being able to obtain substantially the same effect as in the first embodiment, air trying to accumulate inside the damming portion 3i passes through the air hole 3t and flows into the flow path 4e. Therefore, cosmetics that are released and are poorly fluid can be suitably stored in the damming portion 3i.

  In addition, this air hole 3t is applicable also to the blocking part 3i of 2nd-6th embodiment.

  As described above, the present invention has been specifically described based on the embodiment. However, the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, a cosmetic having poor fluidity is particularly dammed up. Although the damming portion 3i is configured to be concave as it can be stored, it may have a shape close to a flat plate.

  In the above embodiment, two guide ports 3j and two guide passages communicating with the guide ports 3j are provided as being particularly suitable. However, one or more guide channels may be used.

  Moreover, in the said embodiment, although the guide path 3k is comprised so that it may extend in the axial direction of a guide cylinder, the inclined path inclined with respect to the axial direction may be sufficient.
