Description

  The present invention relates to a cap that covers and protects the periphery of an ejection head of an aerosol container and a cap that covers and protects the periphery of a stem of a small gas container. Specifically, the present invention relates to a residue discharge (hereinafter referred to as “gas venting”) function. The present invention relates to an aerosol container cap and a gas container cap.

  For aerosol containers filled with useful substances such as cosmetics and pesticides with specific gases, it is necessary to dispose of them in a state where the useful substances and gas (hereinafter referred to as contents) are used up, that is, degassed. It has been. For this reason, various types of caps that have a degassing function on a cap that is detachably attached to the upper part of the aerosol container so as to cover the periphery of the ejection head of the aerosol container have been proposed.

  In a conventional cap having a gas venting function (for example, Patent Document 1), gas venting is performed by pulling out the ejection head of the aerosol container from the stem and attaching the cap to the aerosol container upside down. Since it is necessary, there was a problem that the degassing operation was not easy. Accordingly, the present applicant has proposed an aerosol container cap that can be easily vented (Patent Document 2).

  In the cap described in Patent Document 2, as shown in FIG. 22, the pressing portion 501 and the plurality of connecting portions 502 are formed adjacent to each other on the upper surface portion of the resin cap 500 by slit-like small gaps C. In addition, the other part of the upper surface part and the pressing part 501 are connected by the elongated connecting part 502. Further, in the cap 500, a plurality of guide protrusions 503 protruding downward are formed in other portions adjacent to the pressing portion 501 on the upper surface portion. In this cap 500, the pressing portion 501 is pushed downward while elastically deforming the connecting portion 502, and the jet head 101 of the aerosol container 100 is pushed down to the maximum lowered position by the pressing portion 501, thereby the residue in the aerosol container 100. Is released into the cap 500 to release gas. In this case, the pressing portion 501 is pushed down while elastically deforming the lower end side between the guide projection portions 503 outward, and when this is pushed down to the lower end of the guide projection portion 503, the guide projection whose upper surface is returned to the original position. Since the lower end of the portion 503 is abutted and positioned, the ejection head 101 can be continuously pressurized.

  With this cap 500 attached to the aerosol container 100, even if the ejection head 101 is not pulled out from the stem 102, depressing the pressing portion 501 downward and positioning it can continuously degas. it can.

Japanese Patent Laid-Open No. 10-264958 JP 2004-75161 A

  However, in the cap 500, some force acts on the pressing portion 501 of the cap 500 for a short time during transportation or storage of the new aerosol container 100 filled with the contents, and the pressing portion 501 is the lower end of the guide projection 503. When pushed down to the bottom, there was a problem that all the contents in the aerosol container 100 were released to the outside. For this reason, when the contents of the cap 500 are flammable, there is a risk of causing an explosion or a fire in the aerosol container 100 during transportation or storage, which is problematic in terms of safety.

Further, in the cap 500, since the descending amount of the pressing portion 501 is constant, for example, due to a difference in design specifications by the manufacturer with respect to the aerosol container 100 having the same diameter or an error in manufacturing the aerosol container 100, the ejection head When a slight difference occurs in the maximum lowering position, the ejecting head 101 cannot be pushed down to the maximum lowering position by the pressing portion 501, and the contents in the aerosol container 100 cannot be completely discharged even if degassing. There was a problem.

  On the other hand, portable gas stoves that are used outdoors or placed on an indoor table are disposable, filled with tens to hundreds of grams of gas fuel (for example, liquefied petroleum gas such as liquefied butane gas). Many types of small gas cylinders are used. The small gas cylinder is provided with a gas ejection stem similar to the stem 102 of the aerosol container 100 at the upper part. When the stem is pushed down by a predetermined amount while resisting the elastic force, an internal gas is discharged from the stem. Release. In addition, a cap that covers and protects the periphery of the upper stem is attached to the small gas cylinder before use in a state where it can be easily attached and detached.

  In such a small gas container as well as the aerosol container, it is possible to form a pressing portion, a connecting portion, and a guide projection for pushing down the stem on the cap, and to degas using the cap for disposal. is there. However, this small gas container cap has the same problems as the cap 500 of the aerosol container 100.

  Note that the same problem as in the case of the small gas cylinder occurs also in an aerosol container having an ejection head that can be easily attached to and detached from the stem and having a cap covering the periphery of the stem without the ejection head.

  In view of the above points, the present invention is capable of easily degassing an aerosol container or a small gas container by forming a pressing part, a connecting part, and a guide projection part. An aerosol that does not cause safety problems in the aerosol container or small gas container, and can reliably discharge the residue even if there is a slight difference due to design specifications or manufacturing errors in the aerosol container or small gas container An object is to provide a container cap and a gas container cap.

  According to the first aspect of the present invention, the resin material is formed in a concave shape so as to have a side surface portion around the upper surface portion, and the lower side of the side surface portion is fitted to the upper side of the aerosol container via the uneven portion. A cap for an aerosol container that is attached to the aerosol container so as to cover the ejection head that injects the contents by lowering against the elastic force caused by the pressurization, and has an elongated gap or easy breakage in the upper surface portion. Formed by providing an elongate gap having a portion and an elongate gap having an elongate gap or an easily breakable portion on the upper surface portion, one end side is connected to the pressing portion, and the other end side is the Connected to the remaining portion of the upper surface portion, the pressing portion is connected to the remaining portion, and elastically deformed to move the pressing portion downward. And when the pressing part is moved downward, the lowering part is guided downward, and the pressing part protrudes inward. A plurality of guides for positioning the pressing portion by engaging the upper surface of the pressing portion with the locking end when the pressing portion passes through the locking end of the protruding portion. When the aerosol container cap is attached to the aerosol container with the protrusion and the pressing part positioned at the position of the locking end of the guide protrusion, the upper surface of the jet head is below the uppermost position. An elastic deformation portion that elastically deforms the pressure end of the pressing portion for pressurizing the ejection head located at the upper end position of the ejection head at the maximum lowered position. is there.

  In this invention, when the cap for the aerosol container is removed from the aerosol container and the pressing portion formed by the elongated gap of this cap is pushed downward with, for example, a finger or a stick of the hand, the pressing portion is similarly narrow. It moves downward together with the one end side of the connecting part formed in. In this case, since the other end side of the connecting portion is connected to the remaining portion of the upper surface portion and elastically deforms, the pressing portion receives an elastic force that is pulled upward by the connecting portion. In addition, the pressing portion presses the protruding portion outward while being guided by the guide projection portion when moving downward, so that the free end side of the guide projection portion is bent outward. Then, when the upper surface of the pressing portion passes through the locking end of the protruding portion, the guide projection portion returns so that the locking end of the protruding portion is positioned on the upper surface of the pressing portion. Positioning is performed while being pressed against the locking end.

  Next, a cap whose pressing portion is positioned at the locking end of the guide projection is attached to the aerosol container. Even if a downward force is applied to the cap and the ejection head is pushed down to the maximum lowered position by the pressure end of the pressing portion, the cap cannot be sufficiently attached to the aerosol container. However, if a further downward force is applied to the cap, the elastic deformation portion is elastically deformed by the reaction force from the ejection head, and the cap is lowered by shifting the position of the pressing end of the pressing portion upward. Can be attached to an aerosol container. In this case, since the pressure end of the pressing part pushes the spray head of the aerosol container down to the maximum lowered position, all the residue in the aerosol container is ejected into the cap through the spray head, and then the pressing part. It is discharged out of the cap through the gap of the cap formed by the lowering of the cap.

  On the other hand, even if the cap pressing part is pushed downward with the cap attached to the aerosol container, and the ejection head is pushed down to the maximum lowered position at the pressing end of the pressing part, the upper surface of the pressing part is locked to the guide protrusion. Since it does not reach the position of the end, it cannot be positioned at the position of the locking end of the guide projection. Accordingly, when the force that pushes the pressing portion downward is eliminated, the pressing portion returns to the original position by the elastic force of the connecting portion, and the ejection head is not pushed down by the pressing portion. That is, even if the pressing portion is pushed downward with the cap attached to the aerosol container, the residue in the aerosol container cannot be continuously discharged to the outside.

  Here, since the pressing portion is connected to the remaining portion of the upper surface portion at a plurality of locations via a connecting portion having a certain rigidity, the pressing portion does not move downward (droop) due to its own weight or the like. In addition, by providing an easily breakable portion in the elongated gap and breaking it, when the pressing portion is pushed down, the pushing force is slightly increased, but the downward movement due to the weight of the pushing portion etc. is further prevented. be able to. The long and narrow gap may be a thin-film breakable portion on the bottom side of the narrow groove.

  According to a second aspect of the present invention, in the case of the first aspect of the present invention, the guide projection is positioned at the position of the locking end below the locking end of the protruding portion. An anti-sway part for preventing lateral movement of the pressing part is formed.

  In this invention, when pressurizing the upper surface of the ejection head with the pressing end of the pressing portion, it is possible to prevent the pressing portion from moving laterally along the upper surface and changing the position of the pressing end. For example, if the upper surface of the ejection head is inclined obliquely, the pressing part moves laterally along this surface, and the position of the pressure end (especially the vertical position) is likely to change, but an anti-sway part is provided. Thus, the lateral movement of the pressing portion is prevented and the position of the pressure end is prevented from changing.

  According to a third aspect of the present invention, in the case of the second aspect of the present invention, the lower end surface of the steadying portion is placed at the position of the locking end with the pressing portion riding on the steadying portion when lowered. That is, it is cut obliquely so as to return.

  In this invention, even when the pressing portion is pushed down too much, the end portion rides on the lower end surface of the steadying portion, and the pressing portion is in an oblique state, the pressing unit is the oblique lower end surface of the steadying portion And is moved to the position of the locking end by the elastic force of the connecting portion and positioned at the position of the locking end.

  According to a fourth aspect of the present invention, in the case of the invention according to any one of the first to third aspects, the connecting portion opens up and down while twisting with respect to the downward movement of the pressing portion. That is, a bent portion that is elastically deformed into such a shape is provided.

  In the present invention, the connecting portion stretches itself by twisting the bent portion and moving the bent portion up and down (disengaging) in response to the downward movement of the pressing portion. Since the acting force can be suppressed, it can be easily elastically deformed. For this reason, a press part can be moved below with comparatively small force.

  According to a fifth aspect of the present invention, in the case of the invention according to any one of the first to fourth aspects, the upper surface portion has a hollow portion bent downward, and the bottom portion of the hollow portion has the A pressing portion and the connecting portion are formed, and the guide protrusion is formed downward at the position of the remaining portion adjacent to the pressing portion on the lower surface of the hollow portion.

  In this invention, since the pressing part and the connecting part are provided at the bottom of the hollow part formed on the upper surface part of the cap, the user touches the pressing part or the like during normal use or storage, No object is applied to the pressing part or the like, and no gas is accidentally vented from the aerosol container.

  According to a sixth aspect of the present invention, the resin material is formed in a concave shape so as to have a side surface portion around the upper surface portion, and the lower side of the side surface portion is placed on the upper side of the small gas container via the uneven portion. A cap for a gas container that is attached to the small gas container so as to cover a pipe-shaped stem that ejects contents by descending against the elastic force due to pressurization by being fitted, and is elongated on the upper surface portion. A pressing portion formed by providing an elongated gap having a gap or an easily breakable portion and an upper surface portion formed by providing an elongated gap having an elongated gap or an easily breakable portion, one end side being connected to the pressing portion, The other end side is connected to the remaining portion of the upper surface portion, connects the pressing portion to the remaining portion, and elastically deforms to move the pressing portion downward. When the pressing portion is moved downward, the lower portion is formed at the position of the remaining portion surrounding the pressing portion on the lower surface of the upper surface portion. When the pressing portion is elastically deformed by pressurization and passes through the locking end of the protruding portion, a plurality of guide projections for positioning the pressing portion by engaging the upper surface of the pressing portion with the locking end And when the gas container cap in which the pressing portion is positioned at the position of the locking end of the guide projection is attached to the small gas container, the position is below the upper end of the stem at the maximum lowered position. And an elastically deforming portion that elastically deforms the pressing end of the pressing portion for pressing the stem and moves it to the position of the upper end of the stem that is at the maximum lowered position.

  This invention is the same as the invention for the aerosol container cap according to claim 1 except that the gas container cap is attached to the small gas container so as to cover the periphery of the stem of the small gas container. Therefore, the operation of the present invention is the same as that of the invention of the aerosol container cap according to claim 1 except that the pressing portion pushes down the stem of the small gas container to degas the small gas container. It is.

  According to a seventh aspect of the present invention, in the case of the sixth aspect of the present invention, the small gas container is an aerosol container having an injection head that is easily attached to and detached from the stem.

  In the present invention, when the gas container cap is attached to the aerosol container which is a small gas container, the ejection head needs to be removed from the stem. In this case, if the mounting portion for the ejection head is provided in the gas container cap, the ejection head can be prevented from being lost and the ejection head can be easily used.

According to the first aspect of the present invention, even if the pressing portion is pushed down with the cap attached to the aerosol container, the pressing portion is not positioned at the position of the locking end of the guide projection. For this reason, in this invention, even if some force acts on the cap for a short time during transportation or storage of the aerosol container, the ejection head is not continuously pressurized by the pressing portion. It is possible to avoid the safety problem that all the contents are discharged to the outside. Further, in the present invention, the ejection head can be pushed down to the maximum lowered position with a margin for the elastic deformation of the elastic deformation portion. Therefore, in the present invention, even if there is a change in the maximum descending position of the ejection head due to a difference in design specifications or a manufacturing error, the ejection head is changed by changing the elastic deformation amount of the elastic deformation portion by the change amount. Can be pushed down to the maximum lowered position. Therefore, according to the present invention, for example, even if a common cap is used for aerosol containers from different manufacturers , the internal gas can be completely vented, and the production cost of the cap can be reduced by sharing a mold or the like. Etc. can be achieved.

  Furthermore, according to the present invention, the aerosol container can be easily vented without pulling out the ejection head from the stem, and the pressing portion, the connecting portion, and the guide projection portion that are required when venting are provided. Since the resin can be integrally formed with the part, the cap can be easily manufactured.

  According to the second aspect of the present invention, the lateral movement of the pressing portion engaged with the engaging end of the guide projection portion can be prevented, and the change of the position of the pressing end of the pressing portion can be prevented.

  According to invention of Claim 3 of this invention, even if it pushes down a press part too much, this press part can be easily positioned in the position of the latching end of a guide projection part.

  According to invention of Claim 4 of this invention, a press part can be moved below with comparatively little force by changing the bending part of a connection part.

  According to invention of Claim 5 of this invention, a press part is not accidentally pushed unnecessarily and the safety | security of a cap can be improved.

  According to the sixth aspect of the present invention, even when the cap is attached to the small gas container so as to cover the periphery of the stem of the small gas container, the same effect as in the case of the first aspect of the invention can be obtained. Obtainable. Here, when the small gas container is, for example, a small gas cylinder used for a portable gas stove, the gas container cap is not necessary during the use of the cylinder, so store it until the disposal of the cylinder, or When discarding a used cylinder, a new cylinder may be used.

  According to the seventh aspect of the present invention, the same effect as in the case of a small gas container such as a small gas cylinder can be obtained for an aerosol container in which the ejection head is removed from the stem after use. Examples of the case where the injection head is removed to cap after use include, for example, a case where an elongated injection pipe is fixedly attached to the injection head of the aerosol container in order to facilitate injection to a narrow place. is there.

Next, embodiments of the present invention will be described with reference to the drawings.
Embodiment 1. FIG.
FIG. 1 shows an aerosol container cap according to an embodiment of the present invention. As shown in FIG. 1, the cap 1 has a concave shape in which a substantially cylindrical side surface portion 3 is formed downward from the outer peripheral end of the circular upper surface portion 2. For example, the cap 1 is easily elastically deformed, such as polyethylene or polypropylene. For example, the resin material is integrally formed by injection molding so as to have a thickness of 1.2 mm. The cap 1 has an upper portion of the aerosol container 100 so that the convex portion 3a formed on the inner surface side of the lower portion of the side surface portion 3 is fitted into the concave portion E below the outer winding portion 103a of the upper plate 103 of the aerosol container 100. Easy to attach and detach. The cap 1 covers the periphery of the ejection head 101 inserted into the pipe-shaped stem 102 inside the inner winding portion 103b of the upper plate 103 so that the ejection head 101 is not contaminated by dust or the like. The ejection head 101 is protected so that a hand or the like does not touch the ejection head 101 unnecessarily.

  The aerosol container 100 pushes the upper surface 101a of the ejection head 101 downward while resisting the elastic force, and pushes the stem 102 downward, so that the contents W ejected from the stem 102 are fogged from the ejection unit 101b of the ejection head 101. Inject into a shape. In this case, in order to eject all the contents W in the aerosol container 100, the ejection head 101 is lowered by the distance L from the initial position X1 indicated by the solid line in FIG. It is necessary to hold at the lowered position X2. The aerosol container 100 is a medium-sized container having a container diameter D of, for example, 50 mm, and the upper surface 101a of the ejection head 101 has an inclined curved surface so that pressurization with a finger is easy. It has become. The container diameter D may be 35 mm or 66 mm, for example.

  As shown in FIG. 2 and FIG. 5 (a), a circular recess 10 is formed in the center of the upper surface 2 of the cap 1 so as to face downward. A pressing portion 11 and four connecting portions 12 serving as a gas venting unit are formed on a substantially flat bottom portion 10a having a size of 20 mm, and a part of the bottom portion 10a is formed on the lower end side of the oblique side portion 10b of the recess portion 10. Four guide projections 13 that are also degassing means are formed in a state of protruding to the side.

  As shown in FIG. 3, the pressing portion 11 and the four connecting portions 12 are elongate, for example, 0.05 to 0.4 mm wide (preferably 0.05 to 0.25 mm wide) that penetrate the bottom portion 10 a. The slits C are formed so as to be adjacent to each other over substantially the entire bottom portion 10a. In this case, the connecting portion 12 has a side portion 10b of the portion excluding the pressing portion 11 and the connecting portion 12 from the upper surface portion 2 (hereinafter referred to as the remaining portion 2a of the upper surface portion 2), that is, the outer peripheral end of the bottom portion 10a. And connected by a connecting portion Q1. The connecting portion 12 is formed along the outer peripheral edge of the bottom portion 10a by a predetermined distance from the connecting portion Q1, and then is bent by 180 degrees to change its direction and pressed by the connecting portion Q2 at a position advanced by the predetermined distance. It is connected to the part 11. In this case, each connection part 12 is formed so as to be symmetric with respect to symmetry lines H1 and H2 perpendicular to each other passing through the center point S1 of the bottom part 10a.

  As shown in FIGS. 2 and 3, the pressing portion 11 is formed with a pressing protrusion 11a that presses the upper surface 101a of the ejection head 101 downward in the center on the lower surface side. Reinforcing ribs 11b are formed at positions along H2. The pressure protrusion 11a is determined in length so that the pressure end P at the lower end is at a predetermined position. The pressure protrusion 11a is formed in a cylindrical shape, and shortens the cooling time during molding. The reinforcing rib 11b is formed so as to surround the guide protrusion 13 on the end side of the pressing portion 11. The pressing portion 11 is formed with a pressing upper protrusion 11c at the center on the upper surface 11d side.

  For example, the connecting portion 12 is formed in an elongated band shape with a width of 1 mm so as to be easily elastically deformed, and as shown in FIG. 5B, the bent portion 12 a with respect to the downward movement of the pressing portion 11. It is formed into a shape that can be opened and removed up and down while twisting, for example, a shape bent 180 degrees. Therefore, the connecting portion 12 hardly deforms so as to be stretched with respect to the downward movement of the pressing portion 11, and moves the pressing portion 11 downward by a necessary amount with a relatively small force. be able to.

  As shown in FIG. 2 and FIG. 3, the guide protrusions 13 have four equal pitches so as to surround the pressing part 11 at the position of the remaining part 2 a in contact with the pressing part 11 on the lower surface side of the upper surface part 2. It is provided downward. The guide protrusion 13 is formed in a vertically long bar shape, and a protruding portion 13a that interferes with the pressing portion 11 that is descending is formed on the inner pressing portion 11 side. The protruding portion 13a is formed in an oblique shape so as to gradually protrude downward toward the pressing portion 11, and then the lower end of the protruding portion 13a becomes the locking end B for positioning the pressing portion 11 and the pressing portion 11 It is cut almost horizontally to a position where it does not interfere. Further, the guide protrusion 13 is formed with an anti-swaying portion 13b extending below the protruding portion 13a.

  Therefore, when the pressing portion 11 moves downward, the guide projection portion 13 guides the protruding portion 13a to the pressing portion 11 and elastically deforms outward, while guiding the pressing portion 11 downward. Passes through the locking end B of the protruding portion 13a, it returns to its original state, and the upper surface 11d of the pressing portion 11 is engaged with the locking end B of the protruding portion 13a by the elastic force of the connecting portion 12, The pressing part 11 is positioned. When the pressing portion 11 is at a position where the upper surface 11d is abutted against the locking end B of the protruding portion 13a (hereinafter referred to as an engagement position X3), the pressing portion 11 is prevented from lateral movement by the steadying portion 13b.

  By the way, in the same type and the same diameter aerosol container 100 in which the same cap 1 is used, the maximum of the ejection head 101 is caused by a difference in design specifications or an error in manufacturing (for example, an error in the protruding length of the stem 102). The lowered position varies in various ways. In order to cope with such a change in the maximum lowering position X2 of the ejection head 101, the cap 1 shown in FIG. 2 when the pressing portion 11 positioned at the engagement position X3 is attached to the aerosol container 100 is shown in FIG. As shown, the pressing end P1 of the pressing portion 11 is positioned so as to be positioned, for example, below the upper surface 101a of the ejection head 101 that has moved to the maximum lowered position X2 by a distance a. As a result, even if the upper surface 101a of the ejection head 101 is displaced downward by a distance a, the pressing head 11 can pressurize the ejection head 101 to the maximum lowered position X2.

  On the other hand, in the above state, the cap 1 cannot be attached to the aerosol container 100. For this reason, in the cap 1, the upper surface 11d side of the pressing portion 11 is dealt with as an elastic deformation portion K that is easily deformed by a predetermined amount by a reaction force from below. That is, the elastic deformation portion K is elastically deformed by applying a small pressure to the cap 1 on the aerosol container 100 where the pressing portion 11 is in the engagement position X3, and the position of the pressure end P of the pressure protrusion 11a. Is moved upward by the distance a while maintaining a constant pressure. In this embodiment, as the elastic deformation portion K, the upper surface 11d side of the pressing portion 11 is deformed into a convex shape, but this elastic deformation portion K deforms the pressing protrusion 11a of the pressing portion 11 so as to be shortened. Alternatively, the guide protrusion 13 may be elastically deformed obliquely to raise the position of the locking end B of the protruding portion 13a.

  Here, FIG. 4 shows a change in the position of the pressure end P of the pressing portion 11 when the position of the upper surface 101a of the ejection head 101 at the maximum lowered position X2 changes variously due to a difference in design specifications or a manufacturing error. Is shown. The ejection head 101A is positioned at the lowest possible maximum lowered position X2 with respect to the container main body, and the ejection head 101B is assumed at the highest highest lowered position X2 with respect to the container main body. Is positioned. Then, after the pressure end P of the pressing portion 11 pressurizes the upper surface 101a of the ejection head 101A at the maximum lowered position X2, this pressure is applied to pressurize the upper surface 101a of the ejection head 101B at the maximum lowered position X2. The pressure end P needs to be at a position that is raised by an assumed maximum vertical position error amount M that is a difference between the vertical positions of the two.

  That is, in this cap 1, after the pressure end P of the pressing portion 11 at the engagement position X3 presses the ejection head 101A to its maximum lowered position X2, the elastic deformation portion K is elastically deformed from this position. The ejection head 101B can be pressurized to the maximum lowered position X2 by moving by the assumed maximum vertical position error amount M. In this case, the pressure end P of the pressing portion 11 at the engagement position X3 before the movement due to elastic deformation is at the same position as the position of the upper surface 101a of the ejection head 101A positioned at the maximum lowered position X2. The elastic deformation amount of the elastic deformation portion K is determined when the elastic deformation portion K is elastically deformed by a certain amount (hereinafter referred to as a pressurization deformation amount N) simply by lowering the ejection head 101 to the maximum lowered position X2. Is obtained by adding the pressure deformation amount N to the assumed maximum vertical position error amount M.

  The value of the assumed maximum vertical position error amount M should be determined by investigating the actual situation of the aerosol container 100. For example, about 0.3 to 1 mm is considered necessary.

Next, the function and effect of the cap 1 will be described.
In order to degas the aerosol container 100, the cap 1 is first removed from the aerosol container 100. Subsequently, a finger of a hand, for example, a thumb, a forefinger, or a stick is inserted into the recessed portion 10 of the cap 1 and the upper protrusion 11c of the pressing portion 11 is pushed downward. As a result, the pressing portion 11 moves downward while being guided by the guide projection 13 that is elastically deformed outward while being pulled by the connecting portion 12. When the pressing portion 11 passes through the locking end B of the protruding portion 13a, as shown in FIG. 6 (a), the guide protrusion 13 returns to the original position and the elasticity of the connecting portion 12 is reached. The force is positioned at the engagement position X3 of the locking end B of the protruding portion 13a.

  Next, the cap 1 in which the pressing portion 11 is positioned at the engagement position X <b> 3 is attached to the upper portion of the aerosol container 100. Initially, even if the pressure protrusion 11a of the pressing portion 11 pushes down the ejection head 101 of the aerosol container 100 to the maximum lowered position X2, as shown in FIG. The protrusion 3 a of 1 does not completely enter the recess E of the aerosol container 100, and the cap 1 is not sufficiently attached to the aerosol container 100. Subsequently, when the cap 1 is pushed toward the aerosol container 100 with a larger force, the protrusion 3 a is fitted into the recess E as shown in FIG. 7A, and the cap 1 is attached to the aerosol container 100. In this case, the elastically deforming portion K (the upper surface side of the pressing portion 11) is curved and elastically deformed, and the pressing end P of the pressing portion 11 is in a state where the ejection head 101 is pressed to the maximum lowered position X2. , Increase by distance a. Further, the pressing portion 11 receives a force that causes the pressure end P to move laterally along the oblique upper surface 101a of the ejection head 101, but this lateral movement is prevented by the steadying portion 13b.

  When the ejection head 101 moves to the maximum lowered position X2, the content W (residue) in the aerosol container 100 is continuously ejected from the ejection unit 101b of the ejection head 101, and the residue in the aerosol container 100 is discarded when discarded. Are exhausted in a short time. In this case, after the contents W discharged from the ejection head 101 hit the side surface portion 3 of the cap 1, the content W is discharged out of the cap 1 through the hole R generated by the lowering of the pressing portion 11.

  On the other hand, when the pressing portion 11 is moved downward with the cap 1 attached to the aerosol container 100, the upper surface 11d of the pressing portion 11 protrudes from the protruding portion 13a of the guide projection 13 as shown in FIG. Before reaching the locking end B, the pressure end P of the pressure protrusion 11a pushes the ejection head 101 down to the maximum lowered position X2. For this reason, the pressing portion 11 is not positioned at the engagement position X3, and when the force is released from the pressing portion 11, the pressing portion 11 returns to the initial position by the action of the connecting portion 12, and the residue cannot be discharged from the aerosol container 100. .

  As described above, in the cap 1, even when the pressing portion 11 is pushed down with the cap 1 being attached to the aerosol container 100, the pressing portion 11 is positioned at the locking end B of the protruding portion 13 a of the guide protrusion 13. There is no. For this reason, even if some force acts on the cap 1 for a short time during transportation or storage of the aerosol container 100, the ejection head 101 is not continuously pressurized by the pressing portion 11, and the aerosol container 100 All contents are not released to the outside. Therefore, due to the cap 1, a large amount of combustible gas is released from the aerosol container 100, thereby causing an explosion or a fire, and there is no safety problem that threatens human life.

Further, in this cap 1, since the ejection head 101 can be pushed down to the maximum lowered position X2 with a margin corresponding to the amount of elastic deformation of the elastic deformation portion K, the maximum of the ejection head 101 is caused by a difference in design specifications and manufacturing errors. Even if there is a change in the lowered position X2, the ejection head 101 is pushed down to the maximum lowered position X2 by changing the elastic deformation amount of the elastic deformation portion K (on the upper surface 11d side of the pressing portion 11) by the change amount. Can do. Therefore, in this cap 1, the same (common) thing can be used also for the aerosol container 100 from which manufacture makers differ, for example, reduction of the manufacturing cost of the cap 1 by metal mold | die share etc. can be achieved.

  Further, the cap 1 is provided with a bent portion 12a that changes the direction by 180 degrees in the connecting portion 12, and elastically opens (releases) up and down while twisting the bent portion 12a with respect to the downward movement of the pressing portion 11. Since it is deformed, even if the connecting portion 12 is inclined in the vertical direction, it is hardly deformed so as to be stretched, and the pressing portion 11 can be moved downward with a relatively small force.

  Moreover, in this cap 1, since the press part 11, the connection part 12, and the guide projection part 13 which are gas venting means can be integrally formed with the other part of the cap 1, the cap 1 is also easy and Can be manufactured at low cost. In particular, the pressing part 11 and the connecting part 12 can be formed simply by providing a long and narrow gap C on the upper surface part 2 of the cap 1, so that the manufacture is easy.

  Furthermore, in this cap 1, since the press part 11 and the connection part 12 are formed in the bottom part 10a of the hollow part 10 of the upper surface part 2, the user of the aerosol container 100 pushes the press part 11 unnecessarily, Is unlikely to hit the pressing portion 11, and it is possible to prevent the gas from being accidentally vented other than when the aerosol container 100 is discarded.

  In addition, the cap 1 has a gap C, but since the width is small, dust hardly enters the cap 1 from the gap C, and the cap 1 covers the periphery of the ejection head 101. Can fully perform the function.

  Further, in this cap 1, the pressing portion 11 is connected to the remaining portion 2a of the upper surface portion 2 only through the connecting portion Q1 of the connecting portion 12. However, since the connecting portion 12 has a certain rigidity, the pressing portion 11 is pressed. The part 11 and the connecting part 12 do not hang downward due to their own weight.

  The connecting portion 12 is formed in an elongated shape so as to be easily elastically deformed, and is bent and bent so that when the pressing portion 11 moves downward, the bent portion 12a is opened up and down so that a tensile force is not easily generated. Or any shape as long as it is curved and bent. For example, the connecting portion 12 may have a bending angle of the bent portion 12a, for example, 120 degrees or 90 degrees, a plurality of bent portions 12a, or a long meandering shape.

  Also, the number of connecting portions 12 may be two or three, or may be five or more. When an even number of connecting portions 12 are provided, the connecting portions Q1 of the pair of connecting portions 12 are pointed with respect to the center point S1 of the pressing portions 11 so that the pressing portions 11 can be evenly lowered. Desirably, the connecting portions Q1 of the connecting portions 12 are equiangular with respect to the center point S1 of the pressing portion 11 when the connecting portions 12 are provided in an odd number. It is desirable to be provided at a tensioning position. In this case, it is desirable that the length of each connecting portion 12 is the same.

  Furthermore, you may provide the press part 11 and the connection part 12 in a part instead of providing in the bottom part 10a of the hollow part 10 whole.

  Further, the number of the guide protrusions 13 may be two, three, or five or more. For example, in the case of two, the amount of elastic deformation on the upper surface 11d side (elastically deforming portion K) of the pressing portion 11 when the ejection head 101 is pressurized by the pressing portion 11 can be increased. The protruding portion 13a of the guide protrusion 13 may be formed with any slope or curved surface on the pressing portion 11 side, or may be formed with a partly vertical surface, and the upper and lower lengths may also be The length may be changed variously. As shown in FIG. 8, the shape of the lower end (locking end B) of the protruding portion 13a is also inclined downward toward the inside, and the pressing portion 11 is unlikely to come off the protruding portion 13a when the ejection head 101 is pressurized. May be. In this case, since the deformation on the locking end B side is easy, it is possible to increase the amount of elastic deformation when the ejection head 101 is pressurized by the pressing portion 11. Alternatively, the guide protrusion 13 may not be provided with the steady stop 13b, and the lower end of the guide protrusion 13 may be aligned with the locking end B of the protrusion 13a.

  Furthermore, as shown in FIG. 9, the lower end surface A of the steady rest 13b provided on the lower side of the guide projection 13 may be inclined downward toward the outside. As a result, even if a part of the pressing part 11 descends excessively and a part of the upper surface rides on the steadying part 13b and the pressing part 11 is inclined as shown by the chain line, the pressing part 11 is connected. The elastic force of the portion 12 moves to the locking end B side along the inclined lower end surface A of the steady rest portion 13b and can be easily positioned at the engaging position X3.

  Further, as shown in FIG. 10, the gap C is formed by providing, for example, a necessary number of easy-to-break portions T having a width of about 0.1 to 1 mm, for example, connecting the pressing portion 11 and the remaining portion 2a. Also good.

  Furthermore, the gap C may be formed by a groove portion having a width of 0.2 to 1 mm, for example, in which the bottom portion on the upper surface side is a thin film-like breakable portion (for example, thickness 0.1 mm).

  Further, a circular sheet that can be easily peeled off may be attached to the upper surface portion 2 of the cap 1. Thus, dust and the like can be prevented from entering the cap 1 through the gap C, and the degassing procedure can be easily described on the circular sheet.

  Furthermore, as shown in FIG. 11, in the case of the aerosol container 100 in which the elongated injection pipe 104 is fixed to the injection portion 101b of the injection head 101 so that the contents W can be injected into a narrow place or the like, the cap An elongated long hole 3b extending in the vertical direction may be formed in 1 and the cap 1 may be attached to and detached from the aerosol container 100 using the long hole 3b. In the aerosol container 100, the injection pipe 104 is obstructed during transportation and storage. At this time, the injection head 101 and the like are removed from the stem 102, and these are attached to the main body of the aerosol container 100 via a tape or the like. As shown in FIG. 21, a cap 20A (see FIG. 21) is formed, and a support portion for the injection head 101 and the injection pipe 104 is formed on the cap 1 and supported by the support portion.

  As shown in FIG. 12, a relatively small pressing portion 11 is formed around the upper protrusion 11 c, a guide protrusion 13 is formed at a position adjacent to the pressing portion 11, and the bottom portion 10 a of the recess portion 10. A relatively large remaining portion 2a may be formed on the side. In this case, the bottom portion 10a side of the remaining portion 2a functions as the elastic deformation portion K.

  Further, the elastic deformation portion K for moving the pressure end P may be provided only in the pressing portion 11 (for example, a convex deformation on the upper surface 11d side or a vertical deformation of the pressure protrusion 11a), or the guide protrusion 13. It may be provided only on the outer side (for example, an inclined deformation outward or inward on the free side), or may be provided on the pressing portion 11 and the guide projection portion 13.

  13 to 15 show a cap 1A according to a modified embodiment. In this cap 1 </ b> A, as shown in FIG. 14, the pressing portion 11 is formed in a disk shape on the center side of the bottom portion 10 a, and the connecting portion 12 is, for example, three identical on the outer peripheral end side of the pressing portion 11. The length thing is formed at equal intervals so that the press part 11 may be enclosed, and three things are formed in the position which the guide projection part 13 contact | connects the press part 11 between the connection parts 12. FIG. In this case, the connecting portion 12 has one end side beside the guide projection portion 13 connected to the remaining portion 2a of the upper surface portion 2 via the connection portion Q1, and the other end side beside the other adjacent guide projection portion 13 is connected to the connection portion Q2. The press part 11 is connected to the remaining part 2a. Further, the guide protrusion 13 is formed downward so as to surround the pressing portion 11, and the inner surface 13a on the pressing portion 11 side is inclined so as to gradually protrude downward toward the pressing portion 11 side. Is formed.

  When depressurizing the aerosol container 100 while pushing the pressing portion 11 downward while guiding the pressing portion 11 to the guide projection portion 13, the connecting portion 12 moves downward on the connecting portion Q2 side and is inclined obliquely up and down as shown in FIG. However, since the same force acts on the three connecting parts 12, the pressing part 11 rotates in the direction of the arrow by a predetermined angle corresponding to the descending amount. The tensile force acting on 12 is reduced. Therefore, the pressing portion 11 is pushed downward by a relatively small force, and when the upper surface 11d of the pressing portion 11 passes the lower end or the locking end of the guiding projection portion 13, the elastic force of the connecting portion 12 causes the guiding projection portion 13 to The lower end or the locking end engages with the upper surface 11d of the pressing portion 11, and the pressing portion 11 is positioned at the engagement position. The subsequent operation of the cap 1A is the same as that of the cap 1. In the cap 1A, the upper surface portion side of the pressing portion 11 functions as the elastic deformation portion K.

  Thus, in the cap 1A in which the connecting portion 12 is formed around the pressing portion 11, the force acting to stretch the connecting portion 12 is suppressed as much as possible by rotating the pressing portion 11 in a horizontal state. The pressing portion 11 can be greatly lowered with a small force for the length of the connecting portion 12.

Embodiment 2. FIG.
Next, another embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol as the thing of Embodiment 1 is attached | subjected to the same thing as what was demonstrated in Embodiment 1, or this, and the description is abbreviate | omitted.

  As shown in FIG. 16, the cap 20 is used to cover and protect around the stem 201 of a cassette cylinder (small gas container) 200 used for supplying gas fuel to a portable gas stove. Is. The cap 20 includes a stem 201 that protrudes upward from the concave portion Y by inserting the enlarged diameter portion 22 a formed at the lower portion of the side surface portion 22 into the concave portion Y in the inner winding portion 202 a of the upper plate 202 of the cassette cylinder 200. It is attached to the cassette cylinder 200 so as to cover the periphery. Note that the cap 20 is also integrally formed by resin molding using a mold, like the cap 1.

  Here, the cassette cylinder 200 is, for example, a disposable type filled with, for example, 50 g of liquefied butane gas, which is an odorous liquefied petroleum gas. In this cassette cylinder 200, as shown in FIG. 17, the pipe-like stem 201 is pushed down from the initial position X1 by a predetermined amount to the maximum lowered position X2 while resisting the elastic force, so that the gas is discharged from the stem 201. (Vaporized butane gas) is ejected. The cassette cylinder 200 can be used by placing the cap 20 removed in a portable gas stove, and then pressurizing the bottom and pressurizing and positioning the stem 201 side to the fuel supply unit side. Become. The groove-shaped flange portion 203 formed around the inner winding portion 202a is for positioning the cassette cylinder 200, and is formed with a locking notch portion 203a for preventing rotation. ing. The container diameter D of the cassette cylinder 200 is about 52 mm. For example, when the container diameter D is 65.7 mm, various dimensions are defined by JIS (Japan Industrial Standard) (JIS S 2148). ).

  As shown in FIGS. 17, 18, and 19, the cap 20 has a recess 30 formed downward in the center of the upper surface 21, and the recess 30 is substantially flat, for example, having a diameter of 16 mm. A pressing part 31, four connecting parts 32, and four guide protrusions 33 are formed on the bottom part 30a using the gap C as gas venting means. In addition, the press part 31, the connection part 32, and the guide protrusion part 33 are respectively corresponded to the press part 11, the connection part 12, and the guide protrusion part 13 of the cap 1, and have the same shape and function as these. Is. Accordingly, only the outline of the pressing portion 31, the connecting portion 32, and the guide projection portion 33 will be described, and detailed description thereof will be omitted.

  In the pressing portion 31, an upper protrusion 31c is formed upward in the center on the upper surface side, and a pressing protrusion 31a is formed downward in the center on the lower surface side. A positioning recess U and a gas vent groove Z of the stem 201 are formed at the pressurizing end P at the lower end of the pressurizing protrusion 31a. The upper end of the pressurizing protrusion 31a is close to the surface of the upper protrusion 31c. A ring-shaped V groove V is formed. In addition, four reinforcing ribs 31b are formed in the pressing portion 31 at positions of symmetrical lines H1 and H2 that pass through the center S1 and are orthogonal to each other.

  The connecting portion 32 is a belt-shaped member having a width of about 1 mm and a bent portion 32a of 180 degrees, and is formed so as to be symmetric with respect to the symmetry lines H1 and H2. The connecting portion 32 is connected to the remaining portion 21a excluding the pressing portion 31 and the connecting portion 32 from the upper surface portion 21 by the connecting portion Q1 on one end side, and is connected to the pressing portion 31 by the connecting portion Q2 on the other end side. Yes.

  The guide protrusion 33 is elongated in the downward direction on the remaining portion 21a side of the bottom 30a adjacent to the pressing portion 31 on the symmetry lines H1 and H2. The guide protrusion 33 is formed with a protrusion 33a that protrudes gradually toward the pressing portion 31 toward the inner pressing portion 31 and has a lower end serving as a locking end B. The protrusion 33a is formed below the protrusion 33a. A steady rest 33b is formed. The lower end surface A of the steady rest 33b is an inclined surface that is inclined downward toward the outside.

  The elastic deformation portion K is composed of an upper surface portion K1 around the upper protrusion 31c of the pressing portion 31 and a V-groove outer portion K2 (side surface portion of the upper protrusion 31c) of the pressing portion 31.

Next, the function and effect of the cap 20 will be described.
When degassing from the cassette cylinder 200, the pressing portion 31 of the cap 20 is pressed downward, the upper surface 31 d is pressed against the locking end B, and the pressing portion 31 is moved to the locking end B of the guide projection 33. Position to the position (engagement position X3). Subsequently, the cap 20 is inserted into the recess Y of the cassette cylinder 200. In this case, the pressurizing end P of the pressing portion 31 positions the upper end of the stem 201 in the recess U and lowers the stem 201 to the maximum lowered position X2, but when the cap 20 is further pressurized, it is shown in FIG. As shown in the figure, the upper surface portion K1 of the pressing portion 31 is elastically deformed so as to protrude upward, and the V-groove outer portion K2 of the pressing portion 31 is elastically deformed so as to eliminate the V-groove V. The position of the pressure end P is pushed upward by a predetermined distance a. For this reason, the cap 20 is attached to the cassette cylinder 200 with the enlarged diameter portion 22 a sufficiently inserted into the recess Y. In this state, the gas in the cassette cylinder 200 is discharged from the stem 201 through the gas vent groove Z of the pressing portion 31 into the cap 20 and released into the atmosphere from the hole R generated by the lowering of the pressing portion 31. .

  Further, when the pressing portion 31 is moved downward with the cap 20 attached to the cassette cylinder 200, the pressing end P reaches the stem 201 before the upper surface of the pressing portion 31 reaches the position of the locking end B. Push down to the lowered position X2. For this reason, the pressing portion 31 is not positioned at the engaging position X3, and when the force is released from the pressing portion 31, the pressing portion 31 returns almost to the initial position by the elastic force of the connecting portion 32, and the gas cannot be discharged from the cassette cylinder 200. .

  Thus, with this cap 20, even when some force acts on the cap 20 for a short time during transportation or storage of the cassette cylinder 200, the stem 201 is continuously pressed by the pressing portion 31. Absent. Therefore, the cap 20 does not cause a safety problem because a large amount of combustible gas in the cassette cylinder 200 is released during transportation or storage.

Further, in this cap 20, the stem 201 can be pushed down to the maximum lowered position X2 with a margin corresponding to the elastic deformation of the upper surface portion K1 of the pressing portion 31 and the V-groove outer portion K2. Even if there is a slight change in the position X2, the stem 201 is sufficiently moved to the maximum lowered position X2 by changing the deformation amount of the upper surface portion K1 of the pressing portion 31 and the V-groove outer portion K2 by the change amount. Can be pushed down. Therefore, for example, even if the same cap 20 is used for different cassette cylinders 200 manufactured by different manufacturers , the inside of the cap 20 can be completely degassed. Cost reduction can be achieved.

  Furthermore, with this cap 20, the same effects as those of the cap 1 described in the first embodiment can be achieved with respect to the shape of the connecting portion 32, the manufacture of the cap 20, and the like.

By the way, when the cassette cylinder 200 is used in a portable gas stove, the cap 20 is not necessary during the use of the cylinder 200, so that the cap 20 is stored until the cylinder 200 is discarded, or the used cylinder 200 is discarded. In this case, it is necessary to use a newly used cylinder 200.

  The diameter of the side surface portion 22 of the cap 20 may be increased, and the cap may be attached around the outer winding portion 202 b of the upper plate 202 of the cassette cylinder 200 as the cap 1.

Further, as shown in FIG. 21A, in the case of the aerosol container 100 attached so that the injection pipe 104 is fixed to the injection head 101, the cap is removed from the injection head 101 and the stem 102 is You may make it attach to the aerosol container 100 which became bare. A cap 20A having a gas venting function similar to that of the cap 20 is attached to the aerosol container 100 so as to cover the stem 102 . Similar to the cap 1, the cap 20A is attached around the outer winding portion 103b of the upper plate 103 of the aerosol container 100. A concave portion 34 for supporting the ejection head 101 is formed on the upper portion of the cap 20A. A guide 35 that guides the jet pipe 104 extending from the jet head 101 downward is formed in the lower part of the cap 20 </ b> A following 34.

Therefore, when this aerosol container 100 is used, the ejection head 101 with the ejection pipe 104 is pulled up and removed from the cap 20A, and then the ejection head 101 with the ejection pipe 104 is attached to the stem 102 . Further, when the aerosol container 100 is not used, as shown in FIG. 21B, after the injection head 101 with the injection pipe 104 is pulled out from the stem 102 , the injection pipe 104 is inserted into the guide 35, and The ejection head 101 is fitted into the recess 34 of the cap 20A, and these are attached to the cap 20A. Subsequently, the cap 20A to which the ejection head 101 or the like is attached is attached to the aerosol container 100, and the periphery of the stem 102 is protected by the cap 20A. When degassing the aerosol container 100, the cap 20A having the pressing portion 31 positioned at the engagement position X3 may be attached to the aerosol container 100.
