Description

Coated product

Technical Field

The present invention relates to a coated product for coating a coated article such as an instant adhesive.

Background

Conventionally, as such a coated product, the following coated products are known: the tube container housed in the outer container is pressed by pressing the operation receiving portion, whereby the coating material in the tube container can be extruded to the outside through the nozzle (see, for example, patent document 1). This application product has an exterior container body formed of a pair of halves (japanese character: halves) having openings, and a tongue piece serving also as an operation receiving portion is disposed in the opening of each of the halves. These tongues are provided continuously at the rear edge of the opening portion in a posture capable of sandwiching the tube container body from both sides, and are arranged at the opening portion of the outer container body so as to be capable of being pressed from the outside. Namely, the tongue piece has: a clamping portion that fixes a rear end portion of the tube container formed in a planar shape so as to clamp the rear end portion from both sides; and a pressing plate portion that forms an operation receiving portion that is provided so as to face each other so as to expand from a rear end portion side of the tube container toward the opening portion side, wherein the tongue piece faces the opening portion of the outer container main body in a state where the pressing plate portion can be pressed from outside.

In such a configuration, since the pressing plate portion is set along the entire tube container body, even if the pressing plate portion is slightly pressed, the entire tube container body is simultaneously crushed, and there is a problem that the content may continue to flow out excessively.

Detailed Description

An embodiment of the present invention will be described below with reference to fig. 1 to 21.

This embodiment is an embodiment in the case where the present invention is applied to a coated product 1 for coating an instant adhesive a. As shown in fig. 6 to 12, the coated product 1 includes a core 2 for coating an instant adhesive a as a coating material on the core 2, and an outer container 3 for accommodating the core 2.

As shown in fig. 6, 7, and 9 to 12, the core portion 2 includes a tube container 4 containing the instant adhesive a and a nozzle 5 attached to a mouth portion 13 of the tube container 4.

As shown in fig. 9 to 12, the tube container 4 includes a tube container body 11 in which the temporary bonding agent a is contained, and a mouth portion 13 for guiding the temporary bonding agent a in the tube container body 11 to the outside, and a male screw is formed on the outer periphery of the mouth portion 13. Since this tube container 4 has a known structure, further description thereof will be omitted. The instant adhesive a is a cyanoacrylate-based adhesive to which a diarylvinyl photochromic compound that develops color upon irradiation with ultraviolet light of a specific wavelength and that decolors upon irradiation with visible light is added. Specifically, the instant adhesive a in the tube container body 11 develops, for example, a red color, and after being discharged from the nozzle 5 and applied to the target object, the red color fades and changes to colorless and transparent. For example, an instant adhesive is disclosed in Japanese patent application laid-open No. 2013-010052.

As shown in fig. 9 to 12, the nozzle 5 includes a nozzle body 15 and a base end member 17 formed separately from the nozzle body 15, and the nozzle body 15 has a hollow body shape having a coating material flow passage therein and has translucency. The reason why the nozzle body 15 is made to be a translucent member is that the adhesive a is applied through the nozzle 5 at the instant when the red color is visually recognized from the outside.

As shown in fig. 10 to 12, the nozzle body 15 has a tip cut portion 19 at the tip end for performing an appropriate coating operation, a base end cut portion 21 at the base end which is press-fitted into the mouth portion 13 of the tube container 4, and a base end flange portion 23 formed on the outer periphery of the vicinity of the base end of the nozzle body 15.

As shown in fig. 10 to 12, the base end member 17 is a cylindrical member externally fitted to the base end side of the nozzle main body 15, and has substantially the same outer diameter as the base end flange portion 23 of the nozzle main body 15. A large-diameter flange portion 25 is formed on the outer periphery of the base end member 17, and an internal thread 27 to which the mouth portion 13 of the tube container 4 is screwed is formed on the inner periphery of the base end side.

The core 2 described above is housed in the outer container 3. As shown in fig. 1 to 12, the outer container 3 includes an outer container body 6 and a lid 7, the outer container body 6 is a container body that houses a main portion of the core 2, the lid 7 covers an exposed end portion of the core 2, and a base portion 7b of the lid 7 is screwed to a distal end portion 6a of the outer container body 6.

As shown in fig. 6 to 12, the outer container body 6 includes a trunk 29, a front end member 31, a bottom wall member 33, and an operating mechanism 35, the trunk 29 surrounding a main part of the core 2, the front end member 31 being attached to a front end side of the trunk 29, the bottom wall member 33 being attached to a rear end side of the trunk 29, and the operating mechanism 35 being provided in the trunk 29.

As shown in fig. 6 to 12, the trunk 29 is a cylindrical member having a circular cross section, and is formed in a gentle truncated cone shape such that the cross section gradually increases from the front end toward the rear end. A front end boss 37 for housing the base end member 17 of the nozzle 5 is provided on the front end side of the trunk 29, and a bottom wall member attachment portion 39 is provided on the rear end side of the trunk 29. A spiral groove 37a for screwing the front end member 31 is formed in the outer periphery of the front end boss 37. A pair of windows 41 are formed in the middle of the trunk 29. Further, a pair of guide cylinder portions 43 that are open inward are provided adjacent to each other on the rear side of the window 41 in the inner periphery of the trunk 29, and the bottom wall member mounting portion 39 for mounting the bottom wall member 33 is provided on the rear side of each of the guide cylinder portions 43. The trunk 29 in this embodiment is divided into a pair of split trunk elements 45, and the spiral groove 37a, the bottom wall member attachment portion 39, the window 41, and the guide tube portion 43 are provided one by one in each of the split trunk elements 45.

As shown in fig. 6 to 12, the front end member 31 is screwed to the outer periphery of the front end boss 37 of the trunk 29, a pair of screw engagement projections, not shown, which are screwed to the screw groove 37a are provided on the inner periphery of the front end member 31, a screw groove 31a for cap screw engagement is formed on the outer periphery of the front end member 31, and a through hole 31b for passing the nozzle 5 is formed in the center of the front end member 31. That is, the distal end member 31 constitutes the distal end portion 6a of the outer container body 6, and the base portion 7b of the lid 7 is screwed to the outer periphery of the distal end member 31. The nozzle 5 is positioned and fixed to the outer container body 6 by the distal end member 31, and the separation of the distal end side of the half trunk element 45 constituting the trunk 29 is restricted.

As shown in fig. 6, 7, and 9 to 12, the bottom wall member 33 is a disk-shaped member that closes the vicinity of the rear end of the trunk 29 with a fitting margin (japanese patent application) 29a left, and the bottom wall member 33 is provided with a pair of elastic claws 49 on the inner surface thereof, and the fitting margin 29a is used to fit the top 7a of the lid 7 described later to the rear end 6b of the outer container body 6, that is, the rear end of the trunk 29. The elastic claws 49 are elastically engaged with the bottom wall member attachment portions 39 provided on the trunk 29, whereby the bottom wall member 33 is prevented from being detached from the trunk 29, and the separation of the rear end side of the split trunk element 45 constituting the trunk 29 is restricted by the bottom wall member 33.

The operation mechanism 35 presses the tube container body 11 with an operation force applied to the operation receiving portion 51 to discharge the coating material in the tube container body 11. More specifically, as shown in fig. 7 and 10 to 12, the operating mechanism 35 includes: a first pressing portion 53 for transmitting the operation force preferentially to a specific region of the tube container body 11, specifically, a region 11a on the distal end side; a second pressing portion 55 for transmitting the operating force to another region of the tube container body 11, specifically, a region 11b on the rear end side; and an operation force distribution means 57 for pressing the second pressing portion 55 against the other region, i.e., the rear end side region 11b, from a stage at which the pressing operation of the first pressing portion 53 has progressed halfway.

As shown in fig. 7 and 10 to 12, the operating mechanism 35 includes holding bodies 61, the holding bodies 61 being disposed on both sides of the tube container body 11 in pairs, and having the operation receiving portion 51, the first pressing portion 53, the second pressing portion 55, and the guide projection 59, respectively, and the operation receiving portion 51, the first pressing portion 53, the second pressing portion 55, and the guide projection 59 being integrally formed.

As shown in fig. 10 to 12, the holder 61 includes the first pressing portion 53 at a portion corresponding to the front end region 11a of the tube container body 11, and includes the second pressing portion 55 at a portion corresponding to the rear end region 11b of the tube container body 11. Each of the holding members 61 is formed by surfaces that are continuous between the inner surface of the first pressing portion 53 and the inner surface of the second pressing portion 55, and these surfaces face the tube container body 11.

As shown in fig. 1 to 3, 7, and 10 to 12, the operation receiving portion 51 is exposed to the outside through the window 41 of the outer container 3 and can be pressed inward by a finger from the outside.

The operation force distribution means 57 is provided with the operation receiving portions 51 at positions corresponding to the middle of the first and second

pressing portions

53 and 55 on the outer surface of each of the gripping bodies 61, and connects the rear ends 61a of the two gripping bodies 61 to each other in a contactable and separable state by the elastic urging body 63. In this embodiment, the guide projections 59 provided at the base end portions of the respective clamping bodies 61 are inserted into the corresponding guide tube portions 43 in a state in which they can protrude into and retract from each other and allow a slight tilting movement.

The elastic force applying body 63 is elastically deformable until the inner surfaces of the second pressing portions 55 of the two clamping bodies 61 abut against each other, and is formed in a partial ring shape having a notch at a portion thereof. In addition, the elastic force applying body 63 is integrally formed with the two clamping bodies 61. More specifically, both ends of the elastic force applying body 63 facing the notch are integrated with the rear ends 61a of the two holding bodies 61, respectively.

Here, the operation of the operating mechanism 35 described above will be described with reference to fig. 10 to 12.

First, in the initial state shown in fig. 10, the tube container 4 is filled with the instant adhesive a, the first pressing portion 53 of the clamping body 61 is brought into contact with or close to the tube container 4, and the second pressing portion 55 is in a state of being separated from the tube container 4. That is, the two clamping bodies 61 are biased in the direction of opening each other by the biasing force of the elastic biasing bodies 63 that connect the base ends of the two clamping bodies 61 to each other, and are also biased in the direction of separating the base ends of the two clamping bodies 61 from each other, and the guide projections 59 provided at the base end portions of the clamping bodies 61 are each inserted into the corresponding guide tube portion 43 of the trunk 29 to the maximum extent and the second pressing portion 55 is held in the state of being separated from the tube container 4. When the two operation receiving portions 51 are pressed from this initial state, since the two holding members 61 are in a cantilever state, the distal ends of the two holding members 61 preferentially rotate toward the tube container 4, the first pressing portion 53 is pressed against the region 11a on the distal end side of the tube container 4, and the adhesive a in the tube container 4 is instantaneously discharged from the nozzle 5 to the outside. Fig. 11 shows an intermediate state after such an operation is performed to some extent, but when the two operation receiving portions 51 are further pressed from the intermediate state, the squashed state of the region 11a on the tip end side of the tube container 4 becomes large, and the reaction force acting on the first pressing portion 53 of the clamping body 61 from the tube container 4 side gradually increases. When the operation is further continued in this state, the movement of the first pressing part 53 side having a large load is suppressed, and the proximal end side of the clamping body 61 starts to approach against the urging force of the elastic urging body 63. As a result, not only the first pressing portion 53 but also the second pressing portion 55 is pressed against the region 11b on the base end side of the tube container 4, and finally, as shown in fig. 12, the operation can be continued until the tube container body 11 is substantially flattened, and the amount of the adhesive a remaining in the tube container 4 at the moment can be made smaller than that in the conventional case, and the adhesive a can be efficiently pushed out to the outside. Further, the guide projection 59 provided at the base end portion of the clamping body 61 can slightly tilt in the guide cylinder portion 43 and allow the rotation of the two clamping bodies 61 at the stage of shifting from the initial state to the intermediate state. When the intermediate state reaches the final stage, the guide projection 59 slides in a direction of being pulled out from the guide cylinder portion 43.

The cap 7 is detachably screwed to the distal end side of the outer container body 6 described above.

The cap 7 is capable of covering the nozzle 5, which is an exposed end portion of the core 2, and is formed in a shape in which a cross-sectional area gradually increases from a top portion 7a of the cap 7 toward a rear end portion of the outer container 3 as shown in fig. 1 to 4 in a state of being screwed to a front end side of the outer container body 6.

On the other hand, in a state where the lid 7 is not screwed to the outer container body 6, as shown in fig. 13 to 15, the top portion 7a of the lid 7 can be coupled to the rear end portion 6b of the outer container body 6 in an engaging manner. That is, the lid 7 can be fitted with the inner periphery of the fitting margin 29a set at the rear end portion 6b of the outer container body 6, in other words, the rear end portion of the trunk 29, at the top portion 7a thereof.

The top portion 7a of the lid 7 has a polygonal cross section inscribed in the rear end portion 6b of the outer container body 6. More specifically, as shown in fig. 1, 4, 9 and 15, the top 7a of the lid 7 is a polygonal cross-section with rounded corners, and these corners are inscribed on the inner periphery of the rear end of the trunk 29. The curvature radius of the corners of the top portion 7a of the lid 7 is set to be smaller than the radius of the inner peripheral surface of the rear end portion 6b of the outer container body 6, and the corners of the lid 7 are in line contact with the inner peripheral surface of the trunk 29.

As shown in fig. 6 to 8 and 16 to 21, the lid 7 has a double structure including an outer lid 65 and an inner lid 67, the outer lid 65 having a polygonal cross-sectional shape in which both inner and outer peripheral surfaces change from polygonal cross-sectional shape to circular cross-sectional shape from the top portion 7a toward the base portion 7b, and the inner lid 67 being attached to the inside of the outer lid 65.

As shown in fig. 6 to 8 and 16 to 21, the outer lid 65 has a shape in which the inner and outer peripheral surfaces thereof are gradually and continuously changed from a polygonal cross section to a circular cross section from the top portion 7a toward the base portion 7 b. More specifically, the top 7a side of the outer lid 65 has a quadrangular cross section having flat portions 65b gently curved outward between the rounded corners 65 a. The pair of flat portions 65b facing each other of the outer lid 65 are provided with key grooves 69. The key groove 69 is formed between parallel paired ribs 71 provided upright on the flat portion 65 b. Further, engaging portions 73 formed in a stepped shape are provided on the inner surfaces of the other pair of flat portions 65b facing each other of the outer cover 65, that is, the flat portions 65b not provided with the key grooves 69. The outer cover 65 is white or a color close to white.

The inner lid 67 covers the nozzle 5, which is the exposed end of the core 2, to prevent the tip of the nozzle 5 from coming into contact with air and to block the instant adhesive a from visible light reaching the inside of the nozzle 5 having translucency. The inner lid 67 is darker in color than the outer lid 65, more specifically, black. As shown in fig. 6 to 8 and 16 to 21, the inner lid 67 includes: a cylindrical top end capping (japanese: capping) portion 75, the top end capping portion 75 being blocked by a top portion of the top end of the cap connected to the nozzle 5; a large-diameter screw-engaging portion 77 that is located on the proximal end side, that is fitted to the inner periphery of the base portion of the outer lid 65, and that is screw-engaged with the outer container body 6; and an intermediate tapered portion 79, the intermediate tapered portion 79 making the tip end cap portion 75 and the screw joint portion 77 integrally continuous. Further, the outer periphery of the intermediate tapered portion 79 is provided with: a key 81 as a rotation transmitting portion, which is located at a position closer to the top side than the screw engagement portion 77, that is, the top end cap portion 75 side, and which transmits a rotational operation force applied to the outer lid body 65 to the inner lid body 67; and an elastic claw 83, the elastic claw 83 elastically engaging with the engaging portion of the outer cover 65 to prevent the inner cover 67 from being pulled out from the outer cover 65. The key 81 and the elastic claw 83 are formed integrally with the outer periphery of the intermediate tapered portion 79.

As shown in fig. 8 and 16 to 21, the screw joint portion 77 includes an opening hole externally fitted to the distal end member 31 of the outer container body 6, and a pair of screw joint protrusions 85 screwed with the spiral groove of the distal end member 31 are provided on the inner periphery of the opening hole in a protruding manner.

As shown in fig. 8, 16 to 18, and 20, the key 81 is a rib-shaped member that protrudes integrally with the outer periphery of the intermediate tapered portion 79 of the inner lid 67. The key 81 engages with the key groove 69 and acts to transmit the rotational operation force applied to the outer cover 65 to the inner cover 67.

As shown in fig. 8, 16 to 18, and 20, the elastic claw 83 includes: an arm 87 projecting integrally with the outer periphery of the intermediate tapered portion 79 of the inner lid 67 and extending toward the top 7a side; and a claw body 89, the claw body 89 being disposed at a distal end of the arm 87 and engaging with an engaging portion of the outer cover 65.

Fig. 1 showing the above-described embodiment is a perspective view of the state in which the lid 7 is attached to the outer container body 6. Fig. 2 is a front view thereof, fig. 3 is a plan view thereof, fig. 4 is a left side view thereof, and fig. 5 is a right side view thereof. Fig. 6 is a sectional view taken along line a-a in fig. 2. In this embodiment, as shown in fig. 2, the trunk 29 of the outer container body 6 is divided into two parts by a dividing line, and therefore the original hatching does not enter the trunk 29 in fig. 6, but hatching is applied to the trunk 29 in order to make the distinction between the other parts and the trunk 29 clear. Fig. 7 is a sectional view taken along line B-B in fig. 3. Fig. 8 is a perspective view showing a state where the lid 7 is removed from the outer container body 6, and the outer lid 65 of the lid 7 is partially cut away to show the inside. Fig. 9 is an exploded perspective view. Fig. 10 to 12 are explanatory views for explaining the operation, and show cross sections corresponding to fig. 7. Fig. 13 is a perspective view showing a state immediately before the top portion 7a of the lid 7 is engaged with the rear end portion 6b of the outer container body 6. Fig. 14 is a plan view showing a state where the top portion 7a of the lid 7 is engaged with the rear end portion 6b of the outer container body 6. Fig. 15 is a sectional view taken along line C-C in fig. 14. Fig. 16 is an exploded perspective view showing the lid 7, with the outer lid 65 partially cut away to show the inside. Fig. 17 is an exploded perspective view corresponding to fig. 16 with the view angle changed, and the outer cover 65 is cut away to show the inside in a single half. Fig. 18 is a plan view of the cover 7 with the outer cover body 65 cut away to show the interior in a single half of the anterior side. Fig. 19 is a view from direction D in fig. 18. Fig. 20 is a sectional view taken along line E-E in fig. 18, and fig. 21 is a sectional view taken along line F-F in fig. 18. Fig. 19 to 21 show the entire outer cover 65 without cutting it open.

With such a configuration, when the operation receiving portion 51 is pressed as described above, the first pressing portion 53 is first pressed against the tube container body 11 and then the pressing of the second pressing portion 55 is also started, instead of pressing the tube container 4 at a time, so that the discharge amount of the adhesive a as the coating material extruded from the tube container body 11 can be easily and appropriately adjusted. Therefore, the problem that the adhesive a flows out unnecessarily at the moment of the initial operation can be suppressed or prevented. In addition, at the final stage when the instantaneous adhesive a in the tube container 4 is mostly dispensed, the tube container body 11 can be pressed tightly by both the first pressing portion 53 and the second pressing portion 55, and therefore the amount of the instantaneous adhesive a remaining in the tube container 4 can be minimized.

Further, according to the present embodiment, the top portion 7a of the lid 7 removed from the front end portion 6a of the outer container body 6 can be coupled to the rear end portion 6b of the outer container body 6 in an engaged manner, and therefore, the lid 7 does not need to be placed at another place during the coating operation. Therefore, the cap 7 removed from the outer container body 6 can be prevented or prevented from being lost or dropped from the placement position and damaged.

Further, according to the present embodiment, the threaded portion 77 and the portion of the outer lid 65 externally fitted to the threaded portion 77 are formed in a circular cross section, and the threaded portion 77 is not provided with an element for transmitting rotation, so that these portions can be made as thin as possible. Since the key 81 as the rotation transmission portion is provided on the top portion 7a side of the screw engagement portion 77, the key 81 can be disposed at a position close to the center of the cover 7. Further, since the key groove 69 into which the key 81 is engaged is provided on the inner surface of the flat portion 65b of the outer lid 65, the protruding dimension of the key 81 can be reduced, and the entire lid 7 can be smoothly formed into a slender member. Further, since the key 81 as the rotation transmission portion is disposed at a position different from the screw engagement portion 77, the shape of the screw engagement portion 77 and the shape of the rotation transmission portion can be appropriately designed to be an optimum shape. As a result, the degree of freedom in design is improved, a cap with good operability can be realized, and further thinning of each portion can be realized to promote weight reduction of the entire cap 7.

Further, the present invention is not limited to the above-described embodiments.

That is, it is needless to say that the application material is not limited to the above-described instant adhesive which is decolored by irradiation with visible light, and any material such as a general instant adhesive, an adhesive for woodwork, a food and/or a cosmetic having fluidity, or the like may be used as long as it can be extruded from a tube container and applied to the object through a nozzle.

The operation receiving portion is not limited to the above-described member that is provided integrally with the first and second pressing portions on the outer surface of the clamping body and that receives the pressing operation to transmit the pressing operation force for collapsing the tube container via the pressing portion, and may be, for example, a member that indirectly operates the first and second pressing portions.

Of course, the operation mechanism is not limited to the above-described member including the clamp bodies which are arranged on both sides of the tube container body in a pair with the tube container body therebetween and which have the operation receiving portion, the first pressing portion, and the second pressing portion, respectively, and may be, for example, a member in which the first pressing portion and the second pressing portion press the tube container body from only one side toward the fixed wall.

The operation force distribution means may have any configuration as long as it is a member that presses the first pressing part and the second pressing part against the tube container differentially or with a time difference by the operation force, but if it is a member that includes a clamping body having the first and second pressing parts and the operation receiving part and an elastic urging body that elastically urges the clamping body as in the above-described embodiment, the number of parts can be reduced and the structure can be simplified. In particular, if the elastic urging body is a partially annular member that connects the proximal end portions of the gripping bodies as described above, the tilting operation of the gripping bodies in the operation front half region and the contact/separation operation of the proximal end regions of the gripping bodies in the operation rear half region can be realized by a single component. Further, if the elastic force applying body constituting the operation force distributing means is a member that can be elastically deformed until the inner surfaces of the second pressing portions of the two pinching bodies come into contact with each other, the rear end side of the tube container can be efficiently pressed, and the amount of the coating material remaining in the tube container can be reduced as much as possible.

In addition, various modifications can be made within the scope not departing from the gist of the present invention.
