Description

[Technical field]

[0001] The present invention relates to a dispenser for dispensing a paste. [Background technology]

[0002] Paste products such as toothpaste, face wash, and cosmetic creams filled in tube containers have traditionally been extruded by squeezing the container with the user's hands, and the user has had to open and close the lid of the container each time they were used. In order to eliminate the inconvenience of squeezing the container and opening and closing the lid, toothpaste extrusion devices such as those shown in Patent Documents 1 and 2 have been developed. In the above-mentioned Patent Documents 1 and 2, a paste is dispensed onto a toothbrush by pressing a toothbrush mounting portion or button with the toothbrush, but there are concerns about hygiene and health when used by multiple people. Furthermore, when used in a bathroom or washroom, for example, the bottom can come into contact with the sink and cause limescale to form, or moisture can remain on the toothbrush holder, making it easy for bacteria to grow, so there is a demand for toothbrushes that are easier to use.

[0003] [Patent Document 1] JP 2004-49620 A [Patent Document 2] JP 2004-196305 A Summary of the Invention [Problem to be solved by the invention]

[0004] An object of the present invention is to provide a paste dispenser which is excellent in terms of hygiene, ease of use, etc. [Means for solving the problem]

[0005] The paste dispenser of the present invention is a paste dispenser that dispenses a paste filled in a container, and is characterized in that it comprises a case body to which the container can be attached at the upper side and whose back side is fixed to a wall surface, a pump body that is held inside the case body and connected to the container and has a discharge outlet at its lower end side, and an operating member that is held on the front side of the case body so as to be slidable in an approximately horizontal direction, and the pump body is squeezed by horizontally sliding the operating member.

[0006] For example, the rear side of the case body is fixed to the wall of a bathroom or washroom, and a tube container or the like attached to the upper side of the case body is connected to the pump body inside the case body. The operating member is held on the front side of the case body so as to be slidable in a substantially horizontal direction. By sliding this operating member, the pump body is squeezed and the paste is discharged from the discharge port. For example, by manually pushing the operating member in the sliding direction, the paste falls onto a toothbrush held out below the discharge port, so there is no need to bring the toothbrush into contact with the dispenser or container. This allows multiple users to use the same toothpaste tube hygienically, making it possible to use resources without waste.

[0007] In the present invention, a linking member may further be provided that is rotatably held inside the case body and rotates in conjunction with the horizontal sliding of the operating member to press the pump body. For example, by pushing the operating member in the sliding direction, the interlocking member rotates in conjunction with the horizontal sliding of the operating member and presses the pump body, causing the paste to be discharged from the discharge port. When the operating member is released, the interlocking member and the operating member move in opposite directions due to the reaction to the pressure.

[0008] In the present invention, the interlocking member may have a horizontally pressed portion that abuts against the operating member and is pressed horizontally, a shaft portion that is rotatably held inside the case body, and a rotating pressing portion that abuts against the pump body and rotates and presses it. For example, the pump body may include a valve into which the head of the container is inserted, a stem through which the paste passes and which has a discharge outlet at its lower end, and a stem mounting portion for compressing the stem, the stem mounting portion being mounted on the bottom step of the stem which is a stepped annular shape, and the interlocking member may include the horizontally pressed portion below the shaft portion, and the rotating pressing portion which abuts against the stem mounting portion behind the horizontally pressed portion. For example, when a rotating member (interlocking member) is directly rotated to push the pump body (stem mounting part) in the rotational direction, if the distance between the point of action (rotational pressure part) and the fulcrum (shaft part) is constant, the further the force point (the position where the rotating member is pushed) is from the fulcrum, i.e., the lower the force point is, the less force is required to push it up. However, the operation position of the dispenser, which is the point of force, becomes close to the discharge port, and the dispenser ends up having an overall vertically long structure. In the present invention, the operating member is slid toward the back side supported by the wall surface, and the interlocking member is indirectly rotated. This means that the pump body can be rotated without requiring a particularly large force to slide the operating member, and the operating position of the dispenser (operating member) and the discharge outlet are not close to each other, making it easy to achieve a compact structure, especially in terms of vertical width.

[0009] In the present invention, the case body has a rear case fixed to a wall surface, an upper wall on which the container can be attached, a pair of side walls hanging down from both sides of the upper wall, a pair of groove rails on the lower side of each of the pair of side walls for slidingly holding the operating member, and the pump body inside the pair of side walls, and the operating member may have a pair of sliding portions that slide along each of the pair of groove rails and a horizontal pressing portion, and the groove rail may have a locking portion on the front side for locking the sliding portion and a cutout portion on the rear side from which the sliding portion can be removed. For example, when the operating member is slid horizontally to the front side, the sliding portion engages with the engaging portion. By releasing the engagement between the groove rail and the sliding portion via the notch, the operating member can be removed from the rear case, making it easy to clean the inside of the case body, etc. Effect of the Invention

[0010] The paste dispenser of the present invention has a tube container or the like attached to its upper side, and can dispense the paste from the outlet on the lower side by horizontally sliding the operating member on the front side. Therefore, for example, there is no need to contact a toothbrush or the like with the dispenser, making it hygienic and easy to use. [Brief description of the drawings]

[0012] The paste dispenser according to the present invention will now be described with reference to the drawings. An example of the structure of a paste dispenser 10 is shown in an exploded perspective view in FIG. FIG. 2 is an explanatory diagram for explaining assembly, FIG. 3 is a front view, FIG. 4 is a cross-sectional view, FIG. 5 is a right side view, and FIGS. 6(a) and (b) are bottom views. Dispenser 10 is intended to be fixed to the wall of a bathroom, washroom, etc., and has a container 1 filled with a paste (also called a paste-like semi-liquid material) such as toothpaste, facial cleanser, or cosmetic cream attached to the upper side. When fixing it to the wall, the user can choose a location that is easy for them to use, a place that is less likely to get wet, or a height that children cannot accidentally touch. The container 1 may be, for example, a tube container 1 as shown in FIG. Such a tube container may be a commercially available product that is sold in a state filled with the paste. The container 1 has a body 3 which is closed at one end and connected to a head 2 at the other end, and the paste is filled in the body 3. The paste can be poured out by removing a lid (not shown) which closes the tip opening of the head 2.

[0013] The dispenser 10 includes a rear case 20, a pump body 30 (a valve 31, a valve holder 32, a stem 33, a joint 34, and a stem mounting portion 35), an interlocking member 40, an operating member 50, and a front case 60, as shown in FIG. In this embodiment, the exterior of the dispenser is mainly formed by a rear case 20 fixed to a wall surface, a front case 60 joined to the upper front side of the rear case, and an operating member 50 slidably attached to the rear case below the front case. The pump body 30 is held inside the rear case and front case which are the case body, and its lower end side is located below the case body. The interlocking member 40 is rotatably held inside the case body, and rotates in conjunction with the sliding of the operating member 50 to press the pump body 30. A detailed explanation will be given below, but unless otherwise specified, the shape (for example, annular, approximately U-shaped, etc.) basically refers to the shape in a plan view.

[0014] The pump body 30 includes a valve 31, a valve holder 32, a stem 33, a joint 34, and a stem mounting portion 35. For example, FIG. 2(a) shows these assembled together. The assembled pump body 30 is compact, and the components are excellent in adhesion to each other.

[0015] As shown in FIG. 4(a), the bulb 31 has a substantially spherical bottom portion 312 at the lower end side of an annular base portion 311, and a slit 313 is formed in this bottom portion. The valve is formed of an elastic material such as silicone rubber, and the shape of the slit may be, for example, a straight line shape, a Y shape, a cross shape, or the like. The head 2 of the container 1 is inserted into the insertion hole 314 in the base 311 .

[0016] The valve holder 32 is made of a thermoplastic resin such as ABS resin, and holds the valve 31 . This embodiment has an annular large diameter portion 321 that contacts the outer peripheral surface of the valve base 311, and an annular small diameter portion 322 that extends inward from the lower side of the large diameter portion, with the valve slit 313 located inside the small diameter portion. The large diameter portion 321 has an outer rib 323 that protrudes outward from the lower side of its outer circumferential surface, and a lower rib 324 protrudes downward from the lower surface of the small diameter portion 322 (and / or the large diameter portion 321).

[0017] The stem 33 is made of an elastic material such as silicone rubber so as to be elastically deformed when subjected to pressure. The stem is stepped and annular, with a large-diameter chamber portion 332, a small-diameter bottom step portion 333 at the lower end of the chamber portion, and a nozzle portion 334 extending downward from the bottom step portion. The chamber portion 332 has an annular flange 331 extending outward from its upper end, and a step 336 on its outer circumferential surface that is connected to the bottom step portion 333 . The paste poured out from the container 1 passes through the inside of the chamber, the bottom stage and the nozzle, and is discharged from the discharge port 335 on the lower end side of the nozzle. For example, the lower end of nozzle portion 334 may be roughly V-shaped when viewed from the side or the front, and an elongated outlet 335 extending in the diameter direction of the nozzle portion may be formed at its tip, and outlet 335 is normally (when the operating member is not operated) elastically closed. The stem is assembled into a pump body and comes into contact with the valve holder 32 . In this embodiment, the inner peripheral surface of chamber portion 332 contacts lower rib 324 of the bubble holder, and further, outside lower rib 324, the lower surface of the bubble holder (for example, large diameter portion 321 and outer rib 323) contacts the upper surface of flange 331.

[0018] A joint 34 connecting the valve holder 32 and the stem 33 is made of a thermoplastic resin such as ABS resin. The joint 34 has an annular side portion 341 and an upper inner rib 342 and a lower inner rib 343 which protrude inwardly from the upper and lower ends thereof, respectively. A pair of inner ribs 342, 343 sandwich the outer rib 323 of the valve holder and the flange 331 of the stem, but for example the inner ribs or outer ribs may be formed with locking projections or locking grooves so as to lock with each other.

[0019] The stem mounting portion 35 is fitted and attached to the bottom step portion 333 of the stem, and the chamber portion 332 is compressed by pushing up this bottom step portion. For example, it may be made of a thermoplastic resin such as ABS resin. This embodiment has an annular outer peripheral portion 351 and an annular lower portion 352 extending inward from its lower side, and when attached to the stem, the outer peripheral portion 351 and the lower portion 352 contact the outer peripheral surface and the lower surface of the bottom step portion 333 of the stem, respectively. The upper end of the outer periphery 351 may be located approximately at the step 336 of the stem. As shown in FIG. 6(a), the lower portion 352 of the stem mounting portion has a pair of lower projections 353 that project downward. The pair of lower protrusions 353 are located on both the left and right sides of the nozzle portion 334 of the stem fitted inside the lower portion 352, and serve as rotationally pressed portions that come into contact with a rotationally pressed portion of the interlocking member 40 described later.

[0020] The front case 60 is joined to the upper front side of the rear case 20, and an operating member 50 is attached to the lower front side so as to be slidable in a substantially horizontal (front-rear) direction. In this embodiment, as shown in Figures 3 and 5(a), for example, the upper two-thirds to three-quarters of the front side of the rear case 20 is covered by the front case 60, and the lower one-third to one-quarter is covered by the operating member 50, and the main exterior of the dispenser formed by these is an example of an approximately cubic shape with each side being approximately 60 to 80 mm. Although details will be described later, by arranging the operating member 50, the interlocking member 40 and the pump body 30 in the front-rear direction, a dispenser that is particularly compact in vertical (up-down) width can be obtained, as in this embodiment. The rear case, the front case and the operating members are formed from a thermoplastic resin such as polypropylene.

[0021] The front case 60 may be, for example, substantially U-shaped as shown in FIG. It is preferable that the front case and the rear case have joining protrusions or joining grooves on their abutting edges so that they can engage or fit together, and in this embodiment, joining protrusions 63 are formed on the upper edge of the front wall 61 and the side edges of the front side wall 62.

[0022] The operating member 50 is generally U-shaped with a pair of side frames 52 connected to both sides of a front frame 51, and has horizontal pressing portions 53 on the inside of the pair of side frames 52. The horizontal pressing parts may protrude inwardly to the left or right from the side frames as long as they can press the interlocking member 40 that they come into contact with in the front-rear direction, and there are no particular limitations on the number or shape of the horizontal pressing parts. In this embodiment, a pair of left and right horizontal pressing portions 53 protrude rearward from the rear surface of the front frame 51 . The pair of side frames 52 each have a sliding portion which fits into a groove rail of the rear case, which will be described later, and slides. The sliding portion in this embodiment has a first sliding portion 521 extending from the upper side of the side frame 52 to the inside on the left and right, and a second sliding portion 54 extending from the lower side to the inside on the left and right, and is an example in which the second sliding portion serves as an engaging portion to prevent the operating member from detaching from the rear case. The second sliding portion 54 is an example of a roughly L-shape when viewed from the front, extending from the side frame 52 to the left and right inward and with its tip protruding upward, and has a groove portion between the protruding piece and the side frame 52 into which a part of the rear case (the left and right outer groove walls 222a) fits.

[0023] The interlocking member 40 is formed from a thermoplastic resin such as ABS resin. This embodiment is an example of a roughly U-shaped structure having a pair of horizontally pressed portions 43 that come into contact with the horizontal pressing portion 53 of the operating member and are pressed horizontally, an axis portion 44 that is rotatably held on the inner wall of the rear case 20 described later, and a pair of rotating pressing portions 45 that come into contact with the lower protrusion 353 of the stem mounting portion and rotate to press it, and a pair of side pieces 42 connected to both sides of the front piece 41. The horizontally pressed portion 43 is disposed below the shaft portion 44 protruding outward to the left and right from the side piece 42, and the rotating pressing portion 45 protruding inward to the left and right of the side piece 42 is disposed rearward of the horizontally pressed portion 43. However, as long as the rotating pressing portion can abut against the pump body (stem mounting portion) and be rotated and pressed up, it may protrude rearward from the back surface of the front piece, for example.

[0024] The rear case 20 has a pair of side walls 22 extending vertically from both sides of an upper wall 21 and connected to a rear wall 23 , and an inner wall 24 connected to the inside of the pair of side walls 22 . In this embodiment, the front edges of the upper wall 21 and the side walls 22 that come into contact with the front case 60 have joining protrusions (for example, joining protrusions 225) and joining grooves. An attachment hole 211 that is open upward is formed in the upper wall 21, and the attachment hole has, for example, a substantially elliptical shape and has a through hole 212 at approximately the center of the bottom thereof. The inner wall 24 includes a vertical wall 241 roughly parallel to the side wall 22, a connecting wall 242 connecting the vertical wall to the side wall 22 and the rear wall 23, and an upper clamping wall 243 and a lower clamping wall 244 extending inward from the vertical wall 241 and the rear wall 23 and clamping the fitting 34 which constitutes the pump body. A shaft hole 245 penetrating in the left-right direction is formed on the lower front side of the vertical wall 241.

[0025] The side wall 22 of the rear case holds the operating member 50 so that it can slide in a substantially horizontal direction. A groove rail is formed on the lower side of each of the pair of side walls 22. In this embodiment, each of the pair of side walls 22 has a first groove rail 221 on the lower side of the side surface and a second groove rail 222 on the bottom surface side. The first groove rail 221 has a groove that opens to the left and right outer sides and extends in the front-rear direction. For example, as shown in FIG. 4(b), a first sliding portion 521 of the operating member fits and slides between upper and lower groove walls 221a, 221b of a first groove rail whose front end is open. The second groove rail 222 is an example in which a groove that opens downward extends in the front-to-rear direction and has a front groove wall 223 that closes the front end, and as shown in Figure 6(a), for example, the second sliding portion 54 of the operating member fits and slides between the left and right groove walls 222a, 222b. In this embodiment, the second sliding portion 54 (projecting piece) engages with a front groove wall 223 located at the front end of the second groove rail 222, and the front groove wall 223 acts as an engaging portion. For example, as shown in FIG. 5(a), when the locked portion (sliding portion) and the locking portion (front groove wall) are engaged with each other, the front surfaces of the front case 60 and the operating member 50 may be approximately flush with each other. In addition, the first groove rail may have a locking portion on the front side thereof, which engages with the first sliding portion. Also, a cutout portion that allows the slider to be removed may be formed on the back side of the groove rail. In this embodiment, one of the pair of second groove rails (for example, the second groove rail 222 on the right side in FIG. 6(a)) has a notch 224 formed by partially cutting out the rear side of the groove wall 222a on the left and right outer sides. This allows the second sliding portion 54 to be removed from the cutout portion 224, for example, during cleaning, while the sliding portion is held in the groove rail by each groove wall during use (when sliding). The pair of second rails may both have the notches, or the notches may be formed in the first rail.

[0026] A rear wall 23 of the rear case is located on the rear side of the case body and is fixed to the wall surface. The fixing structure may be, for example, double-sided tape, a magnet, a screw fastener, a hook-and-loop fastener, a suction cup, or the like. As shown in FIG. 2(c), a fixing member 11 having an engaging protrusion 12 and an adhesive portion 13 may be used, in which the engaging protrusion 12 of the fixing member 11 is engaged with an engaging groove 231 formed on the back surface of the rear wall 23, and the adhesive portion 13 is attached to the wall surface. With this structure, the rear case can be easily removed from the wall surface by disengaging the fitting grooves 231 from the fitting protrusions 12 of the fixing member. In this embodiment, the rear wall 23 has a rear rib 232 on the lower rear side thereof to facilitate contact with the wall surface. By making the rear rib protrude toward the wall surface in this manner, the rear rib is more likely to be supported in contact with the wall surface, making it easier to slide the operating member located on the front side of the rear rib in the forward and backward directions.

[0027] The assembly of the components of the dispenser 10 will be described with reference to FIG. The pump body 30 is held by the inner wall 24 of the rear case as shown in FIG. 2(b). Specifically, the joint 34 is sandwiched between a pair of sandwiching walls 243 , 244 located on the upper side of the inner wall, and a valve insertion hole 314 is provided so as to correspond to the through hole 212 in the upper wall 21 . As shown in FIG. 3, the head 2 of the container 1 is inserted into the insertion hole 314 via the through hole 212 , and the other end side of the body 3 is positioned within the mounting hole 211 . This allows the container 1 to be attached to the upper side of the rear case. The interlocking member 40 has a pair of shaft portions 44 rotatably held in a pair of shaft holes 245 located on the lower side of the inner wall 24 of the rear case, and the rotation pressing portion 45 faces the lower protrusion 353 of the stem mounting portion. The operating member 50 has first and second sliding portions fitted into the first and second groove rails of the rear case, respectively, and the horizontal pressing portion 53 faces the horizontally pressed portion 43 of the interlocking member. For example, the second sliding portion can be fitted into the second groove rail via the notch 224 . By joining the front case 60 to the rear case 20, the pump body and the interlocking member are positioned inside the case body. The assembled dispenser 10 can be disassembled to facilitate cleaning and the like.

[0028] The method of using the dispenser 10 will now be described with reference to FIGS. With the container 1 (not shown) attached to the top of the dispenser, the operating member 50 is slid horizontally from the front side to the rear side, for example, as shown in FIGS. 5(a) and 5(b). At this time, as shown in Figures 6(a) to (b), the interlocking member (horizontally pressed portion 43) that the operating member (horizontally pressing portion 53) abuts is pressed horizontally toward the rear side, and the stem mounting portion (rotatably pressed portion 353) that the interlocking member (rotating pressing portion 45) abuts is rotated and pressed in the upward direction with the shaft portion 44 as a fulcrum. As a result, as shown in FIGS. 6(c) and 6(d), the bottom portion to which the stem mounting portion 35 is attached is pushed up, and the chamber portion 322 is compressed. When the paste is filled in the stem, the valve slit 313 and the discharge port 335 are closed, but when the chamber section 322 is compressed, the pressure inside the stem increases, so that with the valve slit closed, the discharge port 335 opens and a predetermined amount of paste is discharged. When the operating member 50 is released, the stem returns to its original state due to its elastic force, causing the pressure inside the stem to decrease below that inside the valve. As a result, the discharge port 335 is closed to prevent the paste from leaking out, while the slit 313 of the valve is opened to inject a predetermined amount of the paste from the container 1 into the chamber portion 332 . As the stem returns to its original state, the stem mounting portion 35 descends. The interlocking member (rotating pressing portion 45) against which this stem mounting portion (rotating pressing portion 353) abuts is rotated in the downward direction, and the operating member (horizontal pressing portion 53) against which the interlocking member (horizontally pressed portion 43) abuts is slid horizontally toward the front. The operating member 50 has its sliding portion 54 engaged with the engaging portion 223 of the rear case, stopping its horizontal sliding and returning to the position in the non-operated state.

[0029] 7 and 8 show the second embodiment. Example 2 is an example in which the head portion 2 (insertion hole 314) and chamber portion 332 of the container have larger diameters than Example 1, and is particularly different in that chamber portion 332 has an intermediate expanded diameter portion 332a. As shown in FIG. 8(d), when the stem mounting portion 35 is raised by the biasing forces of the operating member 50 and the interlocking member 40, the chamber portion below the intermediate expanded diameter portion 332a is also pushed up. This makes it possible to increase the amount of compression of the chamber portion. In this embodiment, the nozzle portion 334 is shorter than that in the first embodiment, but there is no particular limit to the length of the nozzle portion. By exposing the lower end side of the nozzle portion below the case body, it is possible for a user to easily grasp the position of the discharge port and to visually confirm the color of the paste passing through the nozzle portion.
