Abstract

A chip stop mechanism capable of suppressing the sagging, outer draw, and solidification of residual contents at and around a contents discharge port. When an operation button (2) in a stationary mode is depressed, a passage member (5) is moved leftward as viewed from the front of the figure by the action of the tapered surface (2c) of the operation button and the contents discharge port (5a) is separated from a seal member (4) to communicate with an external space. In the stationary mode, the discharge port (5a) is not directly closed by the seal member (4) but the seal acting surface (4a) of the seal member is brought into contact with the flange parts (5c) and (24c) of the passage member disposed on the external space side of the discharge port. The operation button is so formed that, when it is returned to that contact state, the portion thereof (the large diameter inner peripheral surface (4b) of the seal member (4)) facing the large diameter outer peripheral surface portion (5b) of the passage member around the discharge port (5a)(to which the residual contents are liable to adhere) is not brought into contact with the large diameter outer peripheral surface portion. A space area for back suction is set between the rear end part of the seal member (4) and the skirt-like part (6b) of a tail plug part (6).

Description

 Specification

 Tip-stop mechanism, pump-type product with tip-stop mechanism, and aerosol-type product with tip-stop mechanism

 Technical field

 [0001] According to the present invention, the discharge port is closed at the end of the discharge operation of the contents of the container body so that the contents remaining in the passage area near the discharge port do not leak to the outside space of the discharge loca. The present invention relates to a tip stop mechanism that prevents sagging in a pump-type container and an outer draw in an aerosol-type container, and a pump-type product and an aerosol-type product having the tip-stop mechanism.

 [0002] In this specification, the side of the outlet of the container contents is referred to as “front”, and the opposite side is referred to as “rear”. That is, the left direction in FIG. 1 is “front” and the right direction is “rear”.

 [0003] Further, the "static mode" and the "operation mode" in this specification are operating states as a pump type product or an aerosol type product. The tip stop mechanism itself sets the contents outlet to the closed state (= shut off from the external space) when in the stationary mode and to the open state when in the operating mode.

 [0004] Similarly, the "pump type" is a type in which the volume of the contents storage space is reduced by the user pressing, for example, an operation part or a part of the container (such as a peripheral surface part). This is a concept that includes the so-called extrusion type and tube type.

 [0005] The contents to be applied include, for example, liquid or cream soaps, shampoos, rinses, cosmetics, emulsions, foaming shaving foams, hair styling foams, as described below. is there.

 Background art

 [0006] As a tip stop mechanism that actively prevents content sagging and measures against outer draw, for example, the following patent document discloses one.

[0007] This tip stop mechanism is roughly

• Control elements (11) • A head (12) that is equipped with the operation member and has a discharge port for contents and a passage area leading to it.

 When operating mode, move to the external space side to open the discharge port, and when returning to the stationary mode, enter the discharge port from the external space side to close the release port ( 13e), an opening and closing member (13)

 • An elastic member that biases the opening and closing member so that the discharge port is closed (15) • A suction space whose volume changes with the transition of the elastic member (17)

 It consists of such.

 [0008] Then, the opening / closing member (13) resists the urging force of the elastic member (15) as the contents are released, and the forward direction (= the direction in which the seal action portion (13e) also moves away the head passage area force. ) To release the opening (operation mode), and at the end of the discharge operation, the opening / closing member (13) returns to the discharge opening closed state by the urging force of the elastic member (15) and the head passage In addition to preventing solidification of the residual contents in the area, the internal volume of the suction space area is expanded, and residual contents such as the discharge port and the head passage area nearby are sucked into the space area. Patent Document 1: JP 2004-329985 A

 Disclosure of the invention

 Problems to be solved by the invention

 As described above, the conventional tip stop mechanism has a responsiveness at the start of discharge of contents and at the end of discharge, and prevents dripping of residual contents such as a discharge port and a head passage area nearby at the end of discharge. Use in terms of solidification prevention, selfish! Become a mechanism!

 [0010] However, when the discharge port is returned from the open state (container operation end mode) to the closed state (container stationary mode), the sealing portion (13e) of the opening / closing member (13) is moved to the discharge port of the head (12). In other words, the outer edge of the discharge port and the outer part in the vicinity (the surface part of the drooping part (12d)) remain exposed to the external space, so that the exposed part The contents adhering to the water may solidify in contact with the outside air and become so-called icicles as the number of uses increases.

As described above, the conventional tip stop mechanism described above is “return from the open state of the discharge port to the closed state. When returning home, the adhering zone, such as the outer edge of the discharge port and the outer portion in the vicinity of it, becomes an external space area, and the contents adhering to it inevitably come into contact with the outside air and solidify. '' Leave room for improvement.

 [0012] It should be noted that this improvement object also includes a tip stop mechanism of a pump container or an aerosol container that does not have a space area for sucking in residual contents, that is, has a knock suction function.

 [0013] In the present invention, when the discharge port is opened (container operation end mode), when the force is returned to the closed state (container stationary mode), the outer peripheral portion of the discharge port (rather than the sealing action inside the discharge port) is applied. The purpose is to prevent not only the discharge port but also the above-mentioned adhesion zone in the vicinity of the discharge port from the external space by the sealing action to prevent the remaining contents of the adhesion zone from solidifying and preventing dripping into the external space. And

 [0014] In addition, when returning the opened release rod to the closed state (= shut-off state with the external space), the discharge port sealing member (for example, sealing action surfaces 4a and 23c described later and the front end side) As a tip stop structure in which the large-diameter inner peripheral surface 4b, 23b) does not come into contact with the adhesion zone, the remaining contents in the adhesion zone are sealed by the sealing member (for example, a bowl-shaped portion 5c, which will be described later) when returning. 24c) and other areas adjacent to the outside (external space) to prevent the residual contents from dripping into the external space, preventing outer draw, and solidifying the sealed part and the outside adjacent area. The purpose is to ensure prevention.

 [0015] In addition, the space area for backsuction is set so that the passage partial force on the downstream side of the content discharge port is continuous in the same direction, so that the efficiency of the knocking action itself is improved. Objective.

 When in the stationary mode, the sheath-like member is held in the contact state with at least the discharge port being housed in the tubular member,

 The contact state is released based on a sliding operation between the sheath-like member and the tubular member accompanying the transition from the stationary mode to the operation mode.

 (2) In (1) above,

 The cylindrical member has an inner peripheral surface (for example, a range from a front end portion (for example, sealing action surfaces 4a, 23c described later) that contacts the sealed portion in the stationary mode to at least a portion facing the discharge port. The large-diameter inner peripheral surfaces 4b and 23b) to be described later are not in contact with the discharge port when returning to the stationary mode after the content discharge operation.

 (3) In (1) or (2) above,

 The cylindrical member (for example, a seal member 4 to be described later) is integrally formed with a head portion (for example, a head 3 to be described later) having a space area for backsuction,

 The sheath-like member (for example, a passage member 5, 5 ′ described later) is integrated with a sliding member (for example, a tail plug portion 6 described later) that moves in the same direction to define a back-success space. And an opening portion (for example, a rear notch portion 5f described later) that is an inflow region of contents from the upstream side of the head portion. To.

 Example 1

 [0023] As described above, the tip stop mechanism of the present invention is applied to both the pump-type container and the air-zone container. In the following embodiments using Figs. For convenience of explanation, a pump type container is assumed.

 Here, FIG. 1 shows an operation mode in which the upper valve is opened while the vertically moving piston is moving downward by the pressing operation of the operation button, and FIGS. 2 (a) to 4 (a). ) Shows the operation end mode when the vertical movement piston has been moved to the lowest position, and FIGS. 2 (b) to 4 (b) show the stationary mode when the vertical movement piston has returned from the operation end mode upward. Each is shown.

 Note that the head 23 in FIG. 4 includes a cylindrical portion in the front-rear direction corresponding to the seal member 4 in FIGS.

 (It is part of the L-shaped passage part 23a).

 Here, for example, the operation member 1, 21, the seal member 4, the passage member 5, 5 ′, the tail plug portion 6, the output passage member 24, etc. are made of polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate, or the like. It is made of plastic, and the coil spring 7 and plate panel 25 are made of metal.

[0027] It should be noted that the elasticity of the coil spring 7 that urges the tail plug portion 6 (passage member 5, 5 ') in the backward direction and the plate panel 25 that urges the arm portion 24g (output passage member 24) in the backward direction. Force up piston 8 Small enough than that of spring 12 biasing in the direction! /.

 That is, the magnitude relationship between these elastic forces is such that when the operation buttons 2 and 22 in the stationary mode (see FIGS. 2 to 4 (b)) are pushed down, the tail plug portion 6 (passage members 5 and 5 ') And the arm 24g (output passage member 24) move forward, and the piston 8 is set so as not to move downward.

 [0029] The basic features of each of the illustrated chip stop mechanisms are outlined:

 (21) In the stationary mode, the contents discharge ports 5a and 24a themselves are not blocked, but the flanges 5c and 24c arranged on the outer space side of the discharge ports are connected to the seal members 4 and the head 23. The contact surfaces 4a and 23c are in contact with each other.

 (22) When returning from the operation end mode to this contact state (stationary mode), this is applied to the outer part around the discharge ports 5a, 24a (= the large-diameter outer peripheral surface parts 5b, 24b where residual contents are likely to adhere). The parts that face each other (the seal member 4 and the large-diameter inner peripheral surfaces 4b and 23b of the head 23) are not contacted.

 (23) In the case of the tip stop mechanism of FIGS. 1 to 3, it is formed between the rear end portion of the seal member 4 and the squirt portion 6b of the tail plug portion 6 (more than the passage portion of the seal member 4). The space area for the backsuction inside the large-diameter head has a mode in which the content passage area force of the passage members 5 and 5 'continues in the same longitudinal direction.

 This has the above-mentioned effects.

[0030] When the user presses down the operation button 2 in the stationary mode as shown in Fig. 2 (b), the operation for shifting to the operating mode in Fig. 1 is as follows.

 (31) First, only the operation button 2 moves its stationary mode position force downward with respect to the head 3, and the tail plug portion 6 and the passage member 5 are moved by the so-called conversion action between the tapered surface 2c and the driven surface 6a. Pushing forward (at this time, the skirt 6b of the tail plug 6 is guided to the inner peripheral surface of the head 3, and the annular protrusion 5e of the passage member 5 is guided to the small-diameter inner peripheral surface 4c of the seal member 4),

(32) The operation button 2 is moved down until the inner ceiling surface and the upper surface of the head 3 are in contact with each other, and the discharge port 5a is set to the final open state (the upper valve 10 remains closed at this time). ,

(33) After the contact, the head 3 further moves down, and the piston 8 integrated therewith is pushed down to increase the pressure of the contents in the storage space area A, thereby setting the upper valve 10 in the open state, and Set the lower valve 11 to the closed state. [0031] By the valve action of the upper valve 10 and the lower valve 11, the contents in the storage space area A flow out from the discharge port 5a of the passage member 5 to the external space along the path indicated by the solid line in the figure.

 [0032] When the user stops pressing the operation button 2, the piston 8 is moved upward by the elastic force of the coil spring 12, and the passage member 5 and the tail plug portion 6 are moved backward by the elastic force of the coil spring 7. To return to stationary mode.

 At this time, the upper valve 10 that moves together with the piston 8 is received by the lower end portion 13 b of the bush-like member 13 and is set in a state in which the hole 8 a for passing the contents is closed.

 [0034] As the volume of the storage space area A increases and its internal pressure decreases with the return to the stationary mode, the lower valve 11 is moved upward by the pressure of the contents of the container body 14 and opened. And the contents flow into the storage space area.

 [0035] With the inflow of the contents, the internal pressure of the storage space area A increases from the above decrease, and the lower valve 11 moves toward the inlet 9c due to this increase in pressure and its own weight. The inlet is closed. In other words, it will be in the stationary mode as shown in Fig. 2 (b).

 [0036] Although the internal pressure of the container is reduced by the amount of the contents of the container main body 14 flowing into the storage space area A, the piston 8 completely returns to the stationary mode as shown in Fig. 2 (b) and the upper valve 10 Until the upper annular end portion 10a contacts the lower end portion 13b of the bush-like member 13, the illustrated dotted arrow path through the decompression prevention hole portion 9b is secured, so that the outside air corresponding to the reduced amount can be obtained. It flows into the upper space of the container body 14 and the internal pressure of the container returns to an appropriate state.

 [0037] As shown in the drawings, each chip stop mechanism in FIGS.

 (41) When returning from the operation end mode to the stationary mode, the large-diameter outer peripheral surface portion 5b, 24b near the discharge port where residual contents are likely to adhere to the large-diameter inner periphery on the front end side of the seal member 4 or the head 23 Surfaces 4b and 23b never touch

 (42) After returning to the stationary mode, the sealing action surfaces 4a and 23c at the front ends of the seal member 4 and the head 23 come into contact with the flanges 5c and 24c which are the outer space areas of the content discharge ports 5a and 24a. , Blocking the discharge port from the external space,

 It has become an aspect.

[0038] Therefore, when returning from the operation end mode to the stationary mode, the remaining contents near the discharge ports 5a, 24a and the outside of the discharge member 5a and the front end portion of the head 23 (related to the sealing operation) The surface part) will not be pushed towards the outside space.

 [0039] In this manner, the dripping prevention action 'outer draw prevention action and solidification prevention caused by removing the factors that the residual contents in the vicinity of the discharge ports 5a, 24a and the outside thereof are positively pushed to the outside space side. Needless to say, the action is effective even for a tip stop mechanism without knock function! ^.

 Note that the tip stop mechanism (No. 1, No. 2) of FIGS. 2 and 3 sets a back suction space on the extension line in the longitudinal direction of the passage members 5 and 5 ′.

 [0041] Therefore, the residual contents of the passage members 5, 5 'including the discharge port 5a when returning to the operation end mode force stationary mode are efficiently sucked into the space region for backsuction.

 [0042] The main points of the tip stop mechanism (part 3) in FIG. 4 differing from those in FIG. 2 and FIG.

 (51) A content passage downstream of the piston 8 is formed by an L-shaped passage portion 23a of the head 23 and an output passage member 24 covering the front side of the passage portion,

 (52) The output passage member 24 is urged rearward by a plate panel 25 fixed to the bowl-shaped base 23f of the head 23,

 (53) A well-known back-sacking action part (for example, Japanese Utility Model Laid-Open No. 5-81052) set in the upstream part on the piston 8 side is used without forming a back-succession space area inside the head. ,

 That is true.

 [0043] It should be noted that as the operation button 22 is pressed, the output passage member 24 is pushed forward by the action of the tapered surface 22c and the panel connecting portion 24h, and the discharge port 24a is set in the open state. When the piston 8 moves downward, a series of operations from the stationary mode to the operating mode is the same as the above (31) to (33).

 [0044] Further, as described above, the operation modes such as the large-diameter inner peripheral surface 23b and the sealing action surface 23c of the head 23 with respect to the discharge port 24a are the same as those of the tip stop mechanism of FIGS. It is.

FIG. 5 shows, for example, the total area of the large-diameter outer peripheral surface portion 5b near the discharge port where residual contents are likely to adhere when returning from the operation end mode of FIG. 2 (a) to the stationary mode of (b). To make it smaller This shows a case where the concave portion is formed on the outer peripheral surface portion.

 [0046] Substantial reduction of the large-diameter outer peripheral surface portion 5b suppresses the degree of adhesion of residual contents when returning to the stationary mode. Of course, the method of forming the concave portion on the outer peripheral surface portion of the large diameter can be applied to the passage member 5 ′ in FIG. 3 and the output passage member 24 in FIG.

 [0047] In the tip stop mechanism described above, the passage members 5, 5 'may be fixed, and the seal member 4 may be moved in the front-rear direction. The direction of the discharge ports 4a and 24a may be other than the downward direction.

 [0048] Further, on the inner peripheral surface of the seal member 4, the outer peripheral surface of the passage members 5 and 5 ', the inner peripheral surface of the front cylindrical portion of the head 23, and the outer peripheral surface of the inner cylindrical portion of the output passage member 24, It is not necessary to form a large diameter part and a small diameter part.

 [0049] It should be noted that when the above chip stop mechanism is applied to an aerosol-type container,

(61) The operating members 1 and 21 are not changed.

 (62) Use a so-called `` stem '' that has almost the same function as piston 8.

 (63) A so-called “stem gasket (corresponding to the upper valve 10)” having an annular outer edge portion fixed to the container side as an opening / closing member of the hole 8a for passing the contents,

 (64) The decompression prevention hole 9b and the lower valve 11 are omitted.

 Become a shape.
