Description

  The present invention relates to a small article case and an eraser, and more particularly to a small article storage case structure for storing and holding an article main body and projecting it by a predetermined amount during use in a hand-held small article.

  For example, an erasure that erases typographical errors or typographical errors with a pencil or other writing instrument is a rubber, plastic or thermoplastic elastomer erasure body, a paper or plastic cover member or storage case (hereinafter referred to as a storage case). It is provided with a basic structure covered by

  The above storage case prevents the eraser body from becoming dirty, prevents the eraser body from being folded or chipped during use, and is also added to plastic erasers that contain vinyl chloride resin as the main component. The main purpose is to prevent the plasticizer, which is a product, from moving to the surface of the eraser body and melting and fouling other plastic products. Project outside from the case.

  When the tip of the eraser body is worn away by use, pull the eraser body out of the storage case with your fingers, or cut off the tip side of the storage case to expose the tip of the eraser body. It was.

  However, in this method of pulling out the eraser body from the storage case with fingers, the eraser body is directly gripped by fingers, so sweat or oil on the finger surface adheres to the eraser body, and the eraser itself is erased. There is a problem that the character performance deteriorates or gets dirty, and the method of cutting out the storage case requires a cutting tool such as scissors, or when it is torn off with a finger, it cannot be cut cleanly and only the appearance shape is damaged. In addition, as the erasing main body becomes smaller with time, it has become difficult to hold with fingers, which has hindered erasing work, and it has become difficult to lose.

  In this regard, various small article cases have been developed that accommodate small articles such as lipsticks so that they can be fed out (see, for example, Patent Documents 1 to 3).

  Although all of these small article cases have different specific structures, the stored items such as lipstick stored in the storage container body are fed out from the opening at the front end of the storage container body by the rotating operation of the feeding section. At the same time, the storage container is again stored in the storage container main body by the storage rotation operation in the reverse direction.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Throughout the drawings, the same reference numeral indicates the same component or element.

Embodiment 1
The erasure according to the present invention is shown in FIG. 1 and FIG. 2, and this erasure 1 is specifically a typographical error or typographical error such as a letter of a sentence or a line of a figure written with a writing instrument such as a pencil or a mechanical pencil. A plastic eraser for erasing, so-called plastic eraser or plastic eraser.

  The eraser 1 is configured such that the eraser body 2 is housed and held in an eraser case (small article case) 3 as a storage case, and the eraser case 3 feeds the eraser body 2 forward. Means) 4 is provided.

  The eraser body 2 has a plastic rectangular parallelepiped shape, and is an elastic article formed by adding a plasticizer or a pigment to a plastic material such as vinyl chloride, as is conventionally known.

  The eraser case 3 is for storing and holding the eraser body 2 that is a hand-held article body so that the eraser body 3 can be fed forward. Specifically, the case body 5 and the feeding portion 4 are integrally formed. This is a plastic injection molded product.

  The case main body 5 is configured to slidably hold the outer peripheral surface of the eraser main body 2. Specifically, the case main body 5 is a front-rear open cylindrical body that slidably surrounds the outer peripheral surface of the eraser main body 2. It is said that.

  In the illustrated embodiment, the eraser main body 2 has a rectangular parallelepiped shape, and its outer peripheral surface, that is, the front surface 2a, the rear surface 2b, and the four side surfaces 2c, 2d, 2e, 2f, four side surfaces 2c, 2d, 2e and 2f are configured to be slidably held by the case body 5.

  The shape dimension of the case main body 5, especially the shape dimension of the inner peripheral surface, is set in relation to the shape dimension of the outer peripheral surface (four side surfaces 2 c, 2 d, 2 e, 2 f) of the eraser main body 2. The eraser body 2 is set so as to hold the eraser body 2 with an appropriate holding force and to allow the eraser body 2 to be fed forward from the case body 5 by a forward pushing action of a feeding portion 4 described later.

  Here, the “appropriate holding force” means that the eraser body 2 is stably held without moving to a fixed position in the case body 5 in the normal state, while the pushing-out action or the like of the feeding portion 4 is pushed. This means a holding force to such an extent that the eraser body 2 moves from the fixed position by the pressure, and in any case, it is determined in consideration of handling at the actual use site.

  As for the actual shape and size of the case body 5, an experiment in which the eraser body 2 to be stored and held is actually mounted and stored in the case body 5 is repeatedly performed, and an optimum value satisfying the above conditions is determined through this experiment. The

  The feeding portion (feeding means) 4 feeds the eraser main body 2 by a forward pushing action by a finger pressing operation, and is provided integrally with a part of the case main body 5.

  Specifically, the feeding portion 4 includes a pushing lever 6 provided corresponding to the outer peripheral surface (four side surfaces 2c, 2d, 2e, and 2f) of the eraser main body 2.

  Corresponding to the fact that the eraser body 2 has a rectangular parallelepiped shape, the pushing lever 6 is provided corresponding to at least the side surface of the outer periphery 1 of the eraser body 2. A pair of push-out levers 6 and 6 are provided to face each other on the two opposing side surfaces of the eraser body 2, that is, the upper and lower side surfaces 2c and 2d.

  As described above, the push lever 6 is integrated with the case body 5 formed of the same plastic material as the case body 5.

  The pushing lever 6 has a base end portion 6a integrally connected to the case body 5 and a distal end portion 6b that can be locked to the outer peripheral surface of the eraser body 2, that is, the upper side surface 2c or the lower side surface 2d. It is said that.

  The specific shape and configuration of the extrusion lever 6 is a plate-like body having a side surface shape that is bent into a chevron V shape, and the front and rear end portions thereof are respectively connected to the base end portion 6a and the extrusion engaging portion 6b. While forming, the peak-shaped peak part 6c in the middle of these front-and-rear end parts 6a and 6b is a pressing part that is pressed by fingers.

  The base end portion 6 a, the push engagement portion 6 b, and the pressing portion 6 c of the push lever 6 have a planar shape that continuously extends linearly in the axial direction of the eraser body 2.

  The push-out engaging portion 6b of the push-out lever 6 has a lower surface 7 as an engagement surface that comes into surface contact with the upper side surface 2c or the lower side surface 2d of the eraser body 2. The engaging surface 7 is provided with a concavo-convex portion 7a for promoting the engaging action with respect to the outer peripheral surface (the upper side surface 2c or the lower side surface 2d) of the eraser main body 2.

  Further, in the illustrated embodiment, the front end edge of the push-out engagement portion 6b has a linear contour shape orthogonal to the front-rear direction of the eraser body 2, but is indicated by a two-dot chain line in FIG. As described above, the contour shape may be a circular curve curved forward.

  Such a contour structure formed by a circular curve has an advantage that the push-out engagement portion 6b can easily bite into an elastic article such as the eraser body 2 of the illustrated embodiment without slippage at the initial stage of engagement. There is.

  The pushing lever 6 is configured such that the pushing engagement portion 6b of the pushing lever 6 is engaged with the upper side surface 2c of the eraser body 2 by elastic deformation of at least the integral connecting portion 8 between the base end portion 6a and the case body 5. The eraser body 2 is pushed forward.

  For this purpose, the base end portion 6a of the pushing lever 6, more specifically, the portion including the integral connecting portion 8 from the base end portion 6a has a thicker cross-sectional shape than other portions. Yes. With such a structure, sufficient elasticity and strength of this portion made of plastic are ensured.

  The push-out lever 6 of the illustrated embodiment has a push-out engaging portion of the push-out lever 6 by elastic deformation of the push-out lever 6 itself in addition to elastic deformation of the integral connection portion 8 between the base end portion 6a and the case body 5. 6b engages with the upper side surface 2c or the lower side surface 2d of the eraser body 2 to push the eraser body 2 forward.

  Further, since the eraser main body 2 is an elastic article, the engagement action of the engagement surface 7 of the push-out engagement portion 6b of the push-out lever 6 with respect to the outer peripheral surface (upper side surface 2c or lower side surface 2d) of the eraser main body 2 is The structure is such that the elasticity of the eraser body 2 is utilized.

  In relation to this, as described above, the front end edge of the push-out engagement portion 6b of the push-out lever 6 may have a contour shape formed of a circular curve curved forward (see a two-dot chain line in FIG. 2).

  The pushing lever 6 is formed in the vicinity of the front open end of the case body 5, and the pushing action space of the pushing lever 6, that is, the operation space, is opened facing the front open end of the case body 5.

  In other words, the distal end portion of the pushing lever 6, that is, the pushing engaging portion 6b is provided facing the front of the case main body 5 and protrudes forward of the case main body 5 during a feeding operation described later (FIG. 4). (See (b) and (c)).

  Thus, in the eraser 1 configured as described above, when the user uses the eraser 1, the user holds the eraser case 3 with his / her fingers as shown in FIG. 3 (a) or (b). While holding, the pressing operation is performed so that the pressing portions 6c and 6c of the pair of upper and lower push-out levers 6 and 6 of the feeding portion 4 are sandwiched simultaneously from the upper and lower sides with the thumb and the index finger. As a result, the push-out action is caused by the elastic deformation of the push-out levers 6 and 6 (elastic deformation of the integral connection portion 8 between the base end portion 6a of the push-out levers 6 and 6 and the case body 5 + elastic deformation of the push-out levers 6 and 6 itself) The eraser body 2 housed in the eraser case 3 is extended forward, and the eraser can be used.

  Further, in the eraser 1, after the eraser body 2 is consumed due to use, a new eraser body 2 is replaced with the used case eraser body 2 instead of the used eraser body 2 which has been consumed and reduced. It is possible to continue using the eraser case 3 by inserting it into the rear end opening side.

  In this case, the eraser case 3 of the present embodiment is not limited to the dedicated eraser body 2 described above, but can be used alone as a storage case for erasers of the same standard on the general market. .

  The feeding operation mechanism of the eraser body 2 by the feeding unit 4 will be specifically described below (see FIG. 4).

(1) The pair of pushing levers 6 and 6 of the feeding portion 4 is normally in the state shown in FIG. 4A, and the engaging surfaces 7b and 6b of the pushing levers 6 and 6 are engaged with each other. 7 is in a disengaged state separated from the upper and lower side surfaces 2c, 2d of the eraser body 2.

(2) For example, in the illustrated embodiment, as described above, the pressing P 6c and 6c of the pair of push-out levers 6 and 6 is pressed simultaneously from both sides (upper and lower sides in FIG. 4) with the thumb and forefinger. As a result, the push-out levers 6 and 6 have the distal end portions of the engagement surfaces 7 and 7 of the push-out engagement portions 6b and 6b mainly due to elastic deformation of the integral connection portion 8 between the base end portion 6a and the case body 5 as shown in FIG. As shown in (b), it engages with the upper and lower side surfaces 2c and 2d of the eraser body 2, respectively.

(3) Further, when the pressing portions 6c and 6c of the two extrusion levers 6 and 6 are pressed P from both sides, the two extrusion levers 6 and 6 are not only elastically deformed by the integral connecting portion 8 but also the extrusion lever 6 While itself is elastically deformed, the engaging surfaces 7 and 7 of the push-out engaging portions 6b and 6b are more strongly engaged with the upper and lower side surfaces 2c and 2d of the eraser main body 2, thereby causing the eraser main body 2 to reach a predetermined amount. Push forward by α.

  In this case, since the eraser main body 2 is an elastic article, the engaging action of the extrusion engaging portions 6b and 6b on the upper and lower side surfaces 2c and 2d of the eraser main body 2 is as follows. By utilizing the elasticity of No. 2, it is possible to obtain a strong engagement state in which the concave and convex portions 7a and 7a of the engagement surfaces 7 and 7 bite into the upper and lower side surfaces 2c and 2d. As a result, there is no relative slip between the pushing engagement portions 6b, 6b of the pushing lever 6 and the upper and lower side surfaces 2c, 2d of the erasing body 2, and the erasing body 2 is reliably moved by a predetermined amount α. Can be pushed forward.

(4) When the pressing force P against the pressing portions 6c and 6c of the pair of pushing levers 6 and 6 is released, both pushing levers 6 and 6 have the elastic restoring force of the pushing lever 6 itself and the base end portion 6a and the case main body. The engagement surfaces 7 and 7 of the push-out engagement portions 6b and 6b are separated from the upper and lower side surfaces 2c and 2d of the eraser main body 2 by returning to the normal state by the elastic return force of the integral connection portion 8 with the member 5. It becomes a joint state.

  In the feeding operation of the series of the eraser body 2, the case body 5 holds the eraser body 2 with an appropriate holding force and pushes the feeding part 4 (6, 6) forward as described above. The eraser body 2 is allowed to extend forward from the case body 5 by the action.

  In other words, the eraser body 2 is stably held at the current position in the case body 5 except when the eraser body 2 is fed out by the feeding unit 4 (6, 6).

  Although not specifically shown, after the eraser 1 becomes usable by the feeding operation of (3) above, for example, in this state, that is, with both the thumb and forefinger, both push-out levers 6, 6 In the state where the pressing portions 6c, 6c are pressed in a sandwiched manner, the outer peripheral surface of the eraser 1 is gripped, and the leading end portion of the erased main body 2 is moved to the character on the paper to be erased. The above characters and the like are frictionally erased by being reciprocated by being pressed against the surface. By taking such an erasing posture, the erasing main body 2 can stably secure a fixed position with respect to the case main body 5, and efficient erasing can be used.

  As described in detail above, according to the eraser case 3 of the present embodiment, the handheld size eraser body 2 is stored and held so as to be able to be fed forward, and the outer peripheral surface 2c of the eraser body 2 is retained. A case main body 5 that slidably holds 2f, and a feeding portion 4 that is provided on a part of the case main body 5 and that feeds out the eraser main body 2 forward by a pushing operation with a finger. Therefore, the following specific effects are exhibited.

(A) It is provided in a part of the case main body 5 that slidably holds the outer peripheral surfaces 2c to 2f of the eraser main body 2, and is fed out by pushing out the eraser main body 2 forward by a finger pressing operation. By providing the portion 4 (6, 6), the eraser body 2 can be exposed from the case body 5 without directly touching the eraser body 2 with fingers, and sweat and oil on the finger surface are erased. Therefore, the original characteristics of the eraser main body 2 are not damaged or soiled.

(B) The feeding section 4 (6, 6) is provided with the pushing lever 6 provided corresponding to the outer peripheral surface of the eraser main body 2 so that the pushing lever 6 is pressed with a finger. The feeding operation can be performed by a simple operation, the structure is small and simple, and the manufacturing cost and the product cost can be kept low.

(C) Since the feeding portion 4 (6, 6) has a simple structure in which the eraser body 2 is fed forward by a pushing operation with a finger, the shape of the case body 5 is restricted. It can be set as the arbitrary shape corresponding to the external shape of the eraser main body 2 accommodated without it.

  In other words, the eraser case 3 of the present embodiment is not restricted by the outer shape of the eraser body 2 to which the shape of the case body 5 is applied, and is, for example, a rectangular parallelepiped eraser body as shown in the figure. In addition to 2, it can be applied to an eraser body (not shown) having another outer shape such as a columnar shape as in Embodiment 5 described later, and is highly versatile.

  In addition, since the shape of the case body 5 can be made to be a shape that faithfully follows the outer shape of the eraser main body 2 that the case body 5 accommodates, the outer shape of the case body 5 can be the same as the shape of the eraser body 2. Almost the same shape and dimension can be realized, and an increase in the shape and dimension of the eraser 1 that is a small article can be minimized, and it is not bulky.

(D) The eraser 1 of the present embodiment is configured such that the eraser body 2 as a hand-held small article is housed and held in the eraser case 3 so that it can be fed forward. The effect of can be demonstrated effectively.

  That is, the eraser 1 has a low product cost and is a mass-produced product. As described above, the eraser case 3 of the present embodiment having a low manufacturing cost and a low product cost is optimal as a storage case for the eraser 1. is there.

  Further, the feeding portion 4 of the eraser case 3 has a structure in which the eraser body 2 housed by a finger pressing operation is fed out by a forward pushing action, so that it is like a conventional eraser case (storage case). In addition, there is no need to grip the eraser body 2 directly with fingers, that is, there is no need to touch it directly, and sweat or oil on the finger surface adheres to the eraser body 2 and the original erasure performance of the eraser deteriorates or is damaged. There is nothing.

Embodiment 2
This embodiment is shown in FIG. 5 and FIG. 6, and the specific structure of the eraser case 3 is modified.

  That is, in the eraser case 3 of the present embodiment, the pushing lever 6 is formed in the vicinity of the front open end of the case body 5, and the pushing action space of the pushing lever 6, that is, the operation space is the front of the case body 5.
