Description

[Detailed description of the invention] The present invention relates to a refill container for sharpening pencils, etc. whose lead inlet/outlet is opened and closed by a slide lid, and the dimensional accuracy of each component making up the container and the slide lid is strictly controlled. It is possible to absorb variations in the dimensional accuracy without having to form a refill, and it is possible to control the sliding of the slide lid and the engagement state of the container body and the slide lid to a constant level, and it is far superior to conventional cases with refills. The purpose of this invention is to obtain a case containing refills that provides high productivity.

Conventionally, refill cases equipped with this type of sliding lid have to be manufactured with strict dimensional accuracy between the container body and the sliding lid attached to it in order to allow the sliding lid to slide smoothly with a moderate operating force. For example, if the slide lid is too large, the frictional resistance between the container body and the slide lid will be large and the slide lid will not slide smoothly, and if the slide lid is too small, the slide lid will not be able to withstand even the slightest impact. As a result, when the container is not in use, the sliding lid moves in the direction of opening the core inlet/outlet, causing phenomena such as the core inside the container being ejected to the outside. In order to prevent the above-mentioned phenomenon, strict dimensional accuracy of each component is required, so the productivity of refill cases is extremely poor.

The present invention provides a refill case for sharpening pencils, etc., which eliminates the above-mentioned drawbacks by having the configuration described in the claims of the utility model registration.

The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

As shown in FIGS. 1 to 5, the container body 1 of the present invention has a rectangular upper body 2 having a cross-sectional shape and an open top surface, and a lower body having a cross-sectional shape and a bottom portion 3. 4, and is a box-shaped container with a core storage chamber formed inside by engaging the respective side walls 2a and 4a and 2a and 4b. In addition, inside the container body 1 formed by the upper body 2 and the lower body 4,
Upper surface portion 7d that shields the upper surface opening 6 of the upper main body 2
An inner member 7 having a cross-sectional shape having a width that can be closely fitted inside the container body 1 and a length slightly shorter than the length of the container body 1 in the longitudinal direction is inserted. A wall portion 8 having a cutout hole 8a is formed at a corner of the tip of the inner member 7, and the gap between the cutout portion 8a and the bottom surface 4c of the lower body 4 constituting the container body 1 is centered. It is formed with an entrance/exit 9. The inner member 7 is configured so as not to be separated from the upper opening 6 of the upper body 2 by a flange 7b formed on its periphery and a flange 10 formed on the periphery of the upper body 2 and protruding inward. has been done.

As shown in FIG. 2, projecting edges 11 are formed on the lower surfaces of the left and right flanges 10 in the longitudinal direction of the upper main body 2, except for the vicinity of the tip where the slide lid is disposed, and the lower main body 2 Recessed grooves 12 that can fit into the projecting edge 11 are similarly formed on the left and right side walls 4a and 4b, and by pressing and fitting them together, the upper main body 2 and the lower main body 4 can be integrated. They are engaged to form a box-shaped container.

The fryer main body 1 formed by the upper main body 2 and the lower main body 4 has an opening 19 at its tip, and the core taken out from the core inlet/outlet 9 is taken out through the opening 19. .

A slide lid 13 is disposed between the tip of the container body 1 and the wall 8, which is the tip of the inner member 7, so as to be slidable in the width direction of the container body 1.
The slide lid 13 has a side wall portion 14 having a side wall shoulder portion 14a capable of shielding the core inlet/outlet 9, and a side wall portion 14b having a side wall shoulder portion 14c facing the tip opening 19 of the container body 1. is formed in a shape having a grip portion 20 protruding from the upper opening 6 of the upper main body 2.

The sliding lid 13 has both side wall shoulders 14a and 14c arranged below the flange 16 protruding from the upper surface of the tip of the inner member 7 and the tip flange 15 of the upper main body 2, so that the sliding lid 13 is It is configured so that it will not come off from the upper opening 6 of the container body 1.

Further, the height h of both side walls 14a and 14b of the slide lid 13 is formed to be slightly longer than the distance H between the flanges 15 and 16 and the bottom surface 4c of the lower body 4, and the slide lid 13 is formed so that the upper body 2 and the bottom It is disposed in a state where it is clamped to the unfixed contact end of the side body 4. Due to the above structure, the slide lid 13 is always pressed down by the pressure between the upper main body 2 and the lower main body 4, thereby absorbing variations in the dimensional accuracy even if the dimensional accuracy of the container main body 1 and the slide lid 13 is not precise. be able to.

In this embodiment, in order to hold the slide lid in a desired arbitrary position, for example, a position that reliably closes the lead inlet/outlet 9, a bottom surface 4c of the lower main body 4 is provided near the lead inlet/outlet 9, as shown in FIG. A projection 17 is provided at the bottom of the sliding lid 13, and a projecting wall 18 is formed at the bottom of the sliding lid 13.When the sliding lid 13 is slid toward the core opening 9, the projection wall 18 is formed by the operating force. 18 gets over the protrusion 17, so that the slide lid 13 is securely locked at the position of the core opening 9. The tip of the frying device body 1 where the slide lid 13 is disposed is connected to the upper body 2 and the lower body 4.
and are not fixed and have the elasticity to expand and deform, so even when the projecting wall 18 climbs over the protrusion 17, no more operating force than necessary is required, and the protrusion is scraped off by wear. Not at all.

In this embodiment, the container body 1 is formed by engaging an upper body and a lower body with an undercut, but they may be fixedly formed by means such as adhesive. Further, although an inner member for forming a core storage chamber is provided within the container body, there is no problem in providing a structure in which a partition wall having a core inlet/outlet is simply provided within the container body.

As described above, the present invention provides a core inlet/outlet in the container body, which is formed by fixing an upper body and a lower body made of an elastic material such as synthetic resin at their peripheral edges except for the vicinity of the front end. A core storage chamber is formed, and a slide lid is fitted inside the container body near the unfixed front end so as to open and close the core opening, and when the slide lid slides near the front end of the container body, Since it is elastically expanded and deformed, it is possible to absorb variations in the dimensional accuracy of the upper and lower bodies and the slide lid in the vicinity of the tip of the container body without having to form them with strict dimensional accuracy. The sliding of the slide lid and the engagement state of the container body and the slide lid can be controlled to a constant level, and it is easy to manufacture, resulting in far superior productivity compared to conventional refill cases. In addition, by adjusting the materials and dimensions of the container body and slide lid, or the length of the unfixed tip of the container body, the pushing force required for sliding the slide lid can be easily set. It is particularly effective as a case containing refills for pencils, etc.
