Is shown. The housing 52 slides on the closure mechanism 12 with respect to the top 27 of the reclosable package 10 to open and close the entrance 26.

The housing 52 is provided with the closure mechanism 12.
A multi-sided containe configured to be secured thereto or configured to reside thereon.
r) is preferred. In the particular embodiment shown in FIGS. 3 and 4, the housing 52 includes a top wall 5.
4 is provided. The term “top” refers to the direction of the slider device 50 shown in FIG. 3, meaning that the wall 54 is oriented above the rest of the housing 52. Of course, it should be understood that if the housing 52 is moved from the direction shown in FIG. 3, the top wall 54 will not be turned up. Top wall 54 also defines an opening 58. The opening 58 connects the top wall 54 to the first part 60.
And the second part 61. The first part 60 generally comprises
It has a uniform plane extending from the periphery of the opening 58 to the end defined by the first end 58. Similarly, the second portion 61 generally has a uniform flat surface extending from the periphery of the opening 58 to the end defined by the second end 56. By each of the first and second parts 60, 61,
Grooves 63, 64 are each defined. Opening 58 and groove 6
The structure 3 and 64 makes it possible to perform injection molding more easily.

The housing 52 includes first and second side walls 3.
A separation structure capable of separating 0 and 40 is provided. That is, when the closure mechanism 34 is closed and the closure mechanism 12 is in the closed state, the separation
(wedge) and the closure members 34, 44
Are applied to pull them apart. In the illustrated embodiment, the housing 52 has a plow or spreader that operates as a separate structure. In the illustrated preferred embodiment, the spreader 66 extends or hangs from the top wall 54.
Spreader 66 includes wedges 68 having first and second angles separated therebetween by gaps 70 (FIG. 5).
Preferably, 69 is provided.

In FIG. 5, the first and second wedges 68,
69 form a wedge 6 from the first end 55 of the slider device 50 to form a triangular spreader 66 as a whole.
It can be seen that they face the opposite ends of 8,69 at an angle to one another. The gap 70 between the first wedge 68 and the second wedge 69 facilitates the production technique of the housing 52 such as injection molding. Preferably, the spreader 66 only partially projects into the closure mechanism 12. The spreader 66 extends only between the open flanges 39, 49, and the closure member 34,
More preferably, it does not penetrate 44. Thereby, it is possible to secure the closure mechanism 12 having a leak prevention function. In the illustrated preferred embodiment, the spreader 66 is about 0.12 from the first portion 60 of the top wall 54.
Preferably, it protrudes 5 inches.

Referring again to FIGS. 3 and 4, the illustrated preferred housing 52 includes first and second side walls 7.
2, 74 are also provided. First side wall 72 and second side wall 7
4 cantilevered from the top wall 54 to form a slide channel 77 therebetween.
Is preferred. In a preferred embodiment,
The first and second side walls 72, 74 are formed by injection molding, together with other parts of the housing 52. That is, the housing 52 is preferably a unitary, unitary, one-piece component without any additional components that are welded, secured, and screwed. As can be seen in FIGS. 3 and 4, the sidewalls 72, 74 have surface treatments, such as ribs 75, to improve user grip and handling.
(texturization) is also possible. In FIG. 5, it is noted that the side walls 72, 74 are spaced apart from each other at the first end 55 of the first part 60; and that they form a protrusion at the center thereof; the same is true of the second part 61. I want to. These features also enhance the user's grip and ease of handling.

The housing 52 preferably includes a system that permits sliding movement of the housing 52 along the closure mechanism 12 without disengaging engagement with the reclosable package 10. In the illustrated embodiment,
The system of the slider housing 52 engages or couples with a particular configuration of the closure mechanism 12. In particular,
The housing 52 includes first and second engagement leg structures 7.
6, 78. The first engagement leg structure 76 includes a first side wall 72 on a portion of the housing 52,
It preferably extends from below the opening 58. FIG.
7 to 7, the leg structure is preferably a hook structure 76, 78.

Referring now to FIG. 6, the first hook structure 76 preferably includes a flange 80 extending laterally from the first side wall 72. A tip 82 oriented toward the top wall 54 extends or projects from the flange 80. That is, the front end 82 is combined with the flange 80 to form the shoulder 48 of the second side wall 40.
And a hook or a clasp for sliding engagement with.

Similarly, the second engagement leg structure 78 extends from the second side wall 74 in a part of the housing 52 and is also a part of the housing 52 and the second side wall 7.
It preferably has a flange 84 below the opening 58 extending from the fourth. Tip 86 extends or projects from flange 84 in the direction of top wall 54. That is, the flange 84 and the tip 86 cooperate to form a hook or clasp for sliding engagement with the shoulder 38 of the first side wall 30. As seen in FIG. 6, the first hook structure 76 is located closer to the top wall 54 than the second hook structure 78. This is because, in the illustrated embodiment, the second side wall 74 is longer than the first side wall 72.

Attention is again directed to FIGS. The first and second hook structures 76, 78 have circular partial cavities 87, 88, respectively, formed therein. These holes 87 and 88 contribute to facilitation of production techniques such as injection molding.

The slider device 50 guides the slider device 50 between the side ends 20 and 22 (FIG. 1) and prevents the slider device 50 from sliding off the end of the package 10 (FIG. 1). Preferably, it is provided. In the illustrated embodiment, the system includes a guide structure 90 (FIG. 4). Guide structure 90
Is preferably designed to project beyond the first and second ends 55, 56 of the top wall 54. This allows the guide structure 90 to detect the side edges 20, 22 before any other structure on the housing 52 engages the side edges 20, 22 of the package 10. The guide structure 90 is preferably suspended from the top wall 54,
In other embodiments, it may be suspended from other portions of the housing 52.

Although other structures can be considered,
In the particular embodiment shown, the guide structure 90 comprises:
First and second bumpers or extending fingers 92, 9
4 is provided. First bumper or finger 92
Is at least about 0.1 mm from the first end 55 of the first part 60.
It preferably protrudes a distance of 0.6 inches (1.5 mm) and is molded as part of the housing 52. The second bumper or finger 94 is similarly
From the second end 56 of the second part 61, at least about 0.06
It preferably protrudes a distance of inches (1.5 mm) and is molded as part of the housing 52.

In operation, the first finger 92 contacts or engages the side end 20 to prevent the housing 52 from sliding off the end of the reclosing package 10. Similarly, the second finger 94 contacts or engages the side end 22 to prevent the housing 52 from sliding off the end of the package 10. Thereby, the guide structure 90 holds the housing 52 within the boundary or the periphery defined by the side edges 20,22.

Referring again to FIG. 4 and FIG. In a preferred embodiment, the housing 52 includes a drag reduction system. That is, the housing 52 is designed to minimize surface contact between the housing 52 and the closure mechanism 12. In the illustrated embodiment, the system includes first and second drag reducing insulators.
andoffs) 96, 97. The first insulator 96
Preferably, it protrudes or extends from the first side wall 72 as a protrusion, pin or rod. Similarly, the second insulator 9
7 protrudes or extends from the second side wall 74. In the illustrated preferred embodiment, the first and second drag reduction insulators 96, 97 project at least about 0.0085 inches (0.22 mm) from their respective side walls. The first insulator 96 preferably extends entirely between the bottom of the first side wall 72 and the top wall 54. Similarly, the preferred second insulator 97 preferably extends entirely between the bottom of the second side wall 74 and the top wall 54.

In operation, the insulators 96 and 97 slide to move the first and second closure sides 30,
And 40 respectively. The protrusion and extension of the insulators 96, 97 relative to the rest of the housing 52 reduces the amount of contact or friction between the surface portion between the housing 52 and the closure mechanism 12. This facilitates the operation of the slider device 50 by the user.

To perform the operation, the slider device 50 is slid with respect to the reclosing closure mechanism 12 in a first direction or a second direction opposite thereto. When the housing 52 is moved from the closed position to the open position, the spreader 66 causes the closure members 34, 44 to move away from each other. The spreader 66 increases the distance between the upper flanges 39 and 49 of the side members 30 and 40, and the slider housing 52 moves along the reclosing package 10 to
When the triangle 6 moves in the "points" direction, the doorway 26 of the package 10 is opened. The opening is performed by the triangle of the spreader 66 functioning as a cam pulling the side members 30, 40 apart, thereby releasing the engagement of the connecting members 34, 44. To close the closure mechanism 12, the slider housing 12 is moved in the opposite direction with respect to the closure mechanism 12. Such closure results in the slide passage 77 between the side walls 72, 74 narrowing at the end 56 (the end remote from the spreader 66) and the end 55 (the spreader 66).
(Near end).
The spreader 66 is not located very far down in the closure mechanism 12 and does not pass between the coupling members 34,44 in any way. Thus, when the slider device 50 is at the closed position, the leakage of the closure mechanism 12 can be prevented. The slider device housing 52 includes the first finger 9.
2 will move until it contacts the end of the notch 28.
To open the package 10, the slider housing 52
Is moved in the direction opposite to the open position. It should be noted that no tools are required for operation.
