Description

Technical Field

[0001] The present invention relates to an actuator for an aerosol with a razor attached thereto, which is attached to an aerosol can filled with a foamy shaving agent, and an aerosol product with a razor attached thereto.

Background Art

[0002] Conventionally, manual safety razors such as T-shaped razors have been widely used as tools for shaving body hair such as beards. When using such a manual safety razor, for the purpose of moistening and softening body hair to facilitate shaving or for the purpose of alleviating the irritation after shaving, soap, shaving foam, shaving gel, etc. are applied beforehand. And, as a certain type of shaving foam, there is an aerosol product configured to include an aerosol container filled with a composition containing a shaving agent and an aerosol agent, and a valve mechanism capable of operating the valve of this aerosol container to discharge a foamy shaving agent. On the other hand, since beard shaving is often done every day, for example, when a user goes on an overnight trip, he has to carry both an aerosol product containing shaving foam and a razor. Also, if he forgets to bring either one, it takes time and effort such as purchasing at the destination, and the overall complexity increases.

[0003] In order to solve such problems, for example, a product in which a razor is pre-mounted on a container containing a shaving agent has been proposed (see Patent Document 1 etc.). However, as disclosed in Patent Document 1, a razor is simply mounted on a container containing a shaving agent. Although it has an excellent effect of preventing forgetting, its usability is still not good, and it is difficult to say that sufficiently high convenience has been obtained. This is the actual situation.

[0005] The present invention solves the above problems and aims to provide an actuator for a razor-equipped aerosol and a razor-equipped aerosol product equipped therewith, which has excellent portability and can easily dispense shaving agent onto the razor blade with a simple configuration, thereby providing high convenience. [Means for solving the problem]

[0006] The razor-equipped aerosol actuator of the present invention is a razor-equipped aerosol actuator that is mounted around a stem provided at the top of an aerosol container, The aerosol container has a cap that surrounds and is attached to the stem, and has a push button connected to the stem that can press down on the stem, and a razor member that is integrally continuous with the cap via a neck portion having a flow path through which the contents of the aerosol container sprayed from the stem can flow, The neck portion has a discharge port formed in close proximity to the razor member. death, Between the discharge port of the neck portion and the razor member, there is a connecting joint that engages with the tip of the neck portion and forms a content accumulation space for accumulating the contents of the aerosol container discharged from the discharge port before they reach the razor member. The aforementioned joint has an outlet that allows the contents to flow out from the contents reservoir space so as to spread the contents onto the back surface of the razor member. The above problem is solved by having the outlet of the joint consist of a plurality of slits that become wider as they move away from the discharge port of the neck portion. Furthermore, the razor-equipped aerosol actuator of the present invention is an aerosol actuator equipped with a razor that is mounted around a stem provided at the top of the aerosol container, The aerosol container has a cap that surrounds and is attached to the stem, and has a push button connected to the stem that can press down on the stem, and a razor member that is integrally continuous with the cap via a neck portion having a flow path through which the contents of the aerosol container sprayed from the stem can flow, The neck portion has a discharge port formed in close proximity to the razor member, The cap has a push button cover that is detachably attached to the cap and covers the outer circumference of the push button in a way that prevents it from being pressed. This will solve the above-mentioned problems.

[0007] The aerosol product with a razor blade of the present invention is characterized by comprising an aerosol container and the above-mentioned actuator for aerosol with a razor blade, which is mounted around a stem provided at the top of the aerosol container. [Effects of the Invention]

[0008] According to the actuator for aerosols with a razor blade and the aerosol product with a razor blade of the present invention, the razor blade can be integrally and continuously mounted to the aerosol container via the neck portion, so by attaching it to the top of the aerosol container in advance, excellent portability is achieved. Furthermore, since the contents of the aerosol container flow along the internal flow path of the neck portion and are discharged from a discharge port formed close to the razor blade, a simple configuration is achieved, and shaving cream can be easily dispensed onto the razor blade with one hand, resulting in high convenience.

[0009] According to the present invention, an aerosol actuator with a razor blade having a connecting joint between the discharge port of the neck portion and the razor blade member, when the valve is activated, the pressure of the spray of contents from inside the aerosol container pushes the contents out from the outlet of the connecting joint onto the back surface of the razor blade, allowing it to be automatically spread. This ensures that shaving agent is reliably and easily dispensed onto the razor blade, providing extremely high convenience. In particular, the outlet of the connecting joint is composed of multiple slits that become wider as they move away from the discharge port of the neck. As a result, the slits become narrower closer to the discharge port of the neck, i.e., where a strong force is acting to push the contents out, so that a portion of the contents flows out towards the razor blade, while the rest is reliably pushed to a position farther from the discharge port and flows out towards the razor blade from the distant slits. This allows the contents to be spread uniformly over the entire surface of the razor blade, making it even easier and more reliable to dispense shaving cream onto the razor blade, resulting in extremely high convenience.

Mode for Carrying Out the Invention

[0011] Hereinafter, the present invention will be described in detail. 〔Aerosol Product with Razor〕 The aerosol product 100 with a razor of the present invention can be used like a manual so-called T-shaped razor. As shown in FIG. 1, it is composed of an aerosol container 101 that also functions as a handle, and an actuator 110 for aerosol with a razor, which is attached so as to surround the stem 102 (see FIG. 2) of the valve mechanism protruding from the aerosol container 101, and a razor member 180 is provided at the tip. The aerosol container 101 can be, for example, one with a diameter of about 15 mm to 30 mm, taking into consideration portability and ease of handling, but is not limited to this. If the aerosol container 101 has a diameter of about 15 mm, it can be filled with, for example, enough shaving agent for three uses. The aerosol container 101 is filled with a shaving agent composition containing, for example, a shaving agent and a propellant, and the shaving agent can take the form of, for example, foam, gel, or cream when sprayed from the stem 102. If the contents have a suitable fluidity, such as foam, gel, or cream, the contents can be reliably and uniformly spread over the entire surface of the razor member 180 via the neck portion 160 and the connecting joint 170, as will be described later. Furthermore, the shaving agent may be dispensed in gel or cream form and then gradually foam, in what is known as a post-foaming gel or post-foaming cream.

[0012] [Aerosol Actuator with Razor Blade] An aerosol actuator 110 with a razor blade according to one embodiment of the present invention is attached to the top of an aerosol container 101, as shown in Figure 2. Specifically, it consists of a cap 120 having a push button 130 that can press the stem 102 of the aerosol container 101, a razor blade member 180 integrally connected via a neck portion 160 having a flow path 161 through which the contents sprayed from the stem 102 can flow, and a push button cover 150 that covers the outer circumference of the push button 130 and is attached to the cap 120 so as to be openable and closable, and the body 121 of the cap 120 is fitted and fixed to the mounting cup 103 on the top of the aerosol container 101 so as to surround the stem 102 provided in its center.

[0013] Inside the body 121 of the cap 120, a nozzle 140 capable of spraying the contents upward is housed, connected to the stem 102 of the aerosol container 101. As shown in Figures 2 and 3, the nozzle 140 is a roughly cylindrical shape extending upward (in the direction of spraying the contents), with a hollow passage 141 inside. It has a small diameter section 142 and a larger diameter section 143 formed below the small diameter section 142 via a step 144. An engagement recess 146 is formed at the upper end of the small diameter section 142 for engaging and supporting the neck section 160, which will be described later. The lower part of the hollow passage 141 has an inner diameter that matches the outer diameter of the stem 102, and the stem 102 is fitted into the hollow passage 141 of the lower part (large diameter section 143) of the nozzle 140, thereby fixing them together. In this specification, "up" and "down" refer to directions generally recognized by the user, and "vertical direction" refers to the direction with the stem side of the aerosol container facing "up". Furthermore, "circumferential direction" refers to the direction of rotation around the axis of the "vertical direction", and "radial direction" refers to the direction toward the axis in a plane perpendicular to the axis of the "vertical direction".

[0014] The body 121 of the cap 120 has a support hole 122 at its top, into which the small-diameter portion 142 of the nozzle 140 is slidably inserted in the vertical direction. In addition, a push button 130 is slidably positioned radially in a push button hole 123 provided on the side of the body 121, which presses the nozzle 140 from a radial direction intersecting the spray direction of the contents.

[0015] As shown in Figure 4, the push button 130 has a protruding portion 131 exposed on its circumferential surface for the user to press, and a base plate 132 that extends radially and is continuous with the protruding portion 131, and is positioned along an axis perpendicular to the vertical direction. The base plate 132 is provided with an elongated hole 133 that is long in the sliding direction (radial direction) of the push button 130. The base plate 132 is positioned within the body 121 of the cap 120 such that the small-diameter portion 142 of the nozzle 140 is inserted into the elongated hole 133. Furthermore, the lower end of the base plate 132 is provided with a side wall 135 that has a tapered surface 134 at its lower end, which is the apex at the sliding end and slopes downward towards the protruding portion 131, and is compatible with the step 144 of the nozzle 140. The mechanism for spraying the contents by pressing the push button 130 is as follows: When the push button 130 is pressed in a direction intersecting the spraying direction of the contents, i.e., radially inward, the tapered surface 134 at the lower end of the side wall 135 slides radially, and the nozzle 140 is pressed in a direction intersecting the sliding direction (downward) via the step 144 of the nozzle 140 which is slidably engaged with the tapered surface 134. This pressing causes the nozzle 140 to descend and push down the stem 102, so that the contents can be sprayed upward through the nozzle tip opening 145, which is the tip of the hollow passage 141 of the nozzle 140.

[0016] The push button cover 150 covers the outer circumference of the push button 130 in a way that prevents it from being pressed, and as shown in Figure 5, it is attached to the body 121 of the cap 120 so as to be openable and closable. The push-button cover 150 has a substantially cylindrical portion 151 that covers the outer circumference of the cap 120 for, for example, about 180°, and an opening 152 is formed in this cylindrical portion 151 that is not connected. Having this opening 152 allows the cylindrical portion 151 to bend slightly, and by fitting the cylindrical portion 151 along the outer circumference of the cap 120 through this opening 152, the push-button cover 150 can be closed. The cylindrical portion 151 of the push button cover 150 has a covering recess 153 that protrudes outward from the center of its inner surface, covering the protruding portion 131 of the push button 130, and the inner circumferential surface other than this covering recess 153 abuts against the outer circumferential surface of the cap 120 to form a contact portion 154. Furthermore, in order to enhance the effect of preventing the push button cover 150 from falling off or shifting position, the push button cover 150 is attached to the cap 120 so as to be rotatable in the circumferential direction with the protrusion 155 as a pivot point, by engaging the downward-projecting protrusion 155, which is provided on one circumferential edge of the cylindrical portion 151, with the recess 125 provided in the recess 124 of the body 121 of the cap 120 shown in Figure 6. On the other end of the cylindrical portion 151, opposite to the circumferential protrusion 155, there is a veneer 156 that protrudes radially outward and extends vertically. By applying force to this veneer 156 with your fingers in the circumferential direction, the push button cover 150 can be opened. In the razor-equipped aerosol product 100, the presence of a push-button cover 150 prevents the push-button 130 from being pressed unless the push-button cover 150 is opened, thus reliably preventing accidental operation of the push-button 130 that controls the spraying of the contents. Furthermore, even when the razor-equipped aerosol product 100 is stored or transported, and is subjected to impacts such as falls or collisions when the contents should not be sprayed, accidental operation of the push-button 130 can be reliably prevented.

[0017] As shown in Figures 7 to 9, the neck portion 160 has a bent fitting neck portion 162 having an internal flow path 161 through which the contents ejected from the stem 102 can flow, and a roughly rectangular box-shaped space-forming portion 163 that is continuous with the tip of the fitting neck portion 162. The discharge port 164, which is the tip opening of the fitting neck portion 162, is connected to the center of the bottom surface of the space-forming portion 163, and the top surface of the space-forming portion 163 is open, with its peripheral opening 165 shaped to match the shape of the outer frame 181 of the razor member 180. The space-forming portion 163 has a flattened shape with its bottom and top surfaces close together, so that the discharge port 164 of the neck portion 160 is positioned close to the razor member 180. The lower part of the flow path 161 has an inner diameter that matches the outer diameter of the engagement recess 146 of the nozzle 140, and the engagement recess 146 of the nozzle 140 is fitted into the flow path 161 at the lower part of the fitting neck 162, thereby fixing them together. In this embodiment, the fitting neck portion 162 of the neck portion 160 is bent in a V-shape, but the presence or absence of this bend, the angle, and the overall length should be designed so that the razor member 180 is positioned in a similar positional and distance relationship to that of a typical T-shaped razor when the aerosol container 101 is held in the hand as the gripping part. Furthermore, the neck portion 160 may be configured to include a pivoting head mechanism. Specifically, the fitting neck portion 162 of the neck portion 160 may be made of a flexible material, and the shaving pressure of the razor blade that comes into contact with the skin may be adjusted by the elastic force of the material.

[0018] As shown in Figure 8, the connecting joint 170 has a plate-shaped portion 172 having an outlet 171 that allows the contents to flow out toward the back surface of the razor member 180, and a roughly rectangular frame-shaped fitting portion 173 that is continuous with the plate-shaped portion 172 and protrudes from the plate-shaped portion 172 toward the neck portion 160. In the plate-shaped portion 172, the outlet 171 is formed as an overhanging portion 175 that is formed to protrude toward the razor member 180 according to the shape of the recess on the back surface of the razor member 180. Furthermore, an engagement hole 174 is formed in the center of the plate-shaped portion 172 of the joint 170, into which the rib 182 of the razor member 180 (described later) is fitted. As shown in Figure 9, the fitting portion 173 is inserted into the space-forming portion 163 of the neck portion 160 and fitted together so that the plate-shaped portion 172 is sandwiched between the peripheral opening 165 of the neck portion 160 and the outer frame 181 of the razor member 180, and the rib 182 of the razor member 180 is fitted into the engagement hole 174, thereby fixing them together as a single unit. By fixing the connecting joint 170 to the neck portion 160, a content accumulation space S is formed, surrounded by the neck portion 160 and the connecting joint 170, where the contents discharged from the discharge port 164 of the neck portion 160 are collected before reaching the razor member 180. The outlet 171 consists of multiple slits that become wider as they move away from the discharge port 164 of the neck portion 160. Specifically, three slits are arranged at approximately equal intervals on each side from the discharge port 164 of the neck portion 160, and each consists of a narrow slit 171a formed at the closest position, a slit of medium width 171b formed at an intermediate position, and a wide slit 171c formed at a distant position. Because the outlet 171 is composed of slits 171a, 171b, and 171c of different widths, the force pushing out the contents from the aerosol container 101 is stronger the closer it is to the discharge port 164 of the neck portion 160 in the contents accumulation space S. At slit 171a, which is close to the discharge port 164, some of the contents flow out towards the razor member 180, but the rest is prevented from flowing out of slit 171a and is pushed out of the contents accumulation space S towards the slit 171c at a more distant position. It then flows out towards the razor member 180 from the intermediate slit 171b and the slit 171c at a more distant position. As a result, the contents can be uniformly spread over the entire surface through the gaps in the razor blade 183 of the razor member 180 from the contents accumulation space S.

[0019] As shown in Figures 10(a) and 10(b), the razor member 180 has a rectangular outer frame 181, a plurality of razor blades 183 mounted on the outer frame 181 so that the direction in which the blades extend is parallel, and a rib 182 provided so as to traverse the central part of the outer frame 181, and is mounted to the fitting neck portion 162 of the neck portion 160 or the aerosol container 101 in an overall T-shape. The plurality of razor blades 183 are offset from each other in the shaving direction perpendicular to the direction in which the blades extend, and are mounted so as to form gaps between the razor blades 183 that communicate with the contents accumulation space S via the outlet 171 of the connecting joint 170. The razor member 180 also has a razor cover 185 to ensure safety by preventing the razor blades 183 from being exposed to the outside when not in use. The razor member 180 may be configured to use various conventionally known replacement blades for safety razors, etc. The razor blade component 180 may be configured to be replaceable by itself, or the entire neck portion, which includes the razor blade component 180, the connecting joint 170, and the neck portion 160, may be configured to be detachable. With this configuration, the razor blade component 180 can be replaced when the contents (shaving agent) remain and the sharpness of the razor blade component 180 decreases.

[0020] In the above-described aerosol product 100 with a razor blade, when the push button 130 is pressed radially inward, the contents are discharged from the stem 102 through the nozzle 140 and neck portion 160 to the discharge port 164 into the contents reservoir space S. While accumulating in the contents reservoir space S, the contents are spread across the entire surface of the razor member 180 through the slits 171a to 171c that constitute the outlet 171 of the connecting joint 170, passing from the back surface of the razor member 180 through the gap between the razor blades 183. On the other hand, when the pressure on the push button 130 is released, the stem 102 returns to its upward position, and the push button 130 is automatically pushed radially outward, stopping the spraying of the contents.

[0021] Although the actuator 110 for a razor-equipped aerosol and the aerosol product 100 for a razor-equipped aerosol according to one embodiment of the present invention have been specifically described above, the embodiments of the actuator 110 for a razor-equipped aerosol and the aerosol product 100 for a razor-equipped aerosol are not limited to the examples described above, and various modifications can be made. For example, the razor member may be configured to be rotatable relative to the neck portion. Specifically, as shown in Figures 11 and 12, the neck portion 260 has a fitted neck portion 262 that is bent in a V-shape and has a flow channel (not shown) inside, and a roughly rectangular box-shaped space-forming portion 263 that is continuous with the tip of the fitted neck portion 262, and these are made as independent members, and the space-forming portion 263 is configured to be rotatably supported relative to the fitted neck portion 262. In Figures 11 and 12, components having the same configuration as the aerosol product 100 with a razor according to the embodiment shown in Figures 1 to 10 are indicated by the same reference numerals. Having such a neck portion 260 allows the member of the neck portion 260 that is closer to the tip than the fitting neck portion 262, namely the space-forming portion 263, and the connecting joint 170 and razor member 180 fixed thereto, to rotate integrally with respect to the fitting neck portion 262. Furthermore, with such a razor-equipped aerosol product 200, since the fitting neck portion 262 is bent in a V-shape, the razor member 180 and the integral member therewith (the space-forming portion 263 of the neck portion 260 and the connecting joint 170) can be rotated together by about 90 degrees, allowing them to be stored along the axis of the aerosol container 101, thereby saving space when not in use and improving portability.
