Description

  The present invention relates to a cap remover used when removing a cap attached to an opening of a container such as a bottle.

  When the used container is discarded, in order to reuse the collected container material, it is necessary to remove the cap made of a different kind of material fitted in the mouth of the container.

  Conventionally, a cap remover 100 shown in FIG. 12 is known as a cap remover used for this kind of cap removing operation (for example, Patent Document 1).

  FIG. 12A is a side view of the cap remover 100. The cap remover 100 includes a remover main body 101 formed by pressing a flat metal piece having a thickness of about 1 mm and a handle portion 102 made of synthetic resin. A notch recess 103 is formed in the abdomen (lower side of the drawing) of the removal tool main body 101. A locking portion 107 is formed at the lower end portion of the base-side hypotenuse 105 of the notch recess 103 so as to project from the base-side hypotenuse 105 toward the distal end of the removal tool body 101 in a generally bowl shape.

  FIG. 12B illustrates a cap removal operation using the cap remover 100. First, the cap remover 100 is put on the mouth portion of the bottle B in which the cap C is fitted from above, the tip side oblique side 104 of the notch recess 103 is brought into contact with the upper end edge of the cap C, and the locking portion 107 is locked to the lower edge of the cap C.

  Then, the cap 102 is pushed up to cause the handle 102 of the cap remover 100 to be raised upward while keeping in contact with the cap C at two positions of the oblique side 104 on the front end side and the locking portion 107. That is, the handle 102 is pushed up so that the cap remover 100 and the cap C rotate about the contact portion between the tip side oblique side 104 and the upper edge of the cap C.

  If it does so, the latching | locking part 107 will dig deeply with respect to the lower end edge of the cap C, and the lower end outer peripheral part of the cap C will be lifted. And the crimping | compression-bonding with the cap C and the bottle B is cancelled | released, and the cap C is removed.

  Moreover, as an example of another prior art, a cap remover 200 shown in FIG. 13 is known (for example, Patent Document 2).

  FIG. 13A is a side view of the cap remover 200. The cap remover 200 includes a cap removal portion 202 having a sharp cross-sectional shape and a sharp shape at the tip of the metal rod 201. A sharp cutting edge 203 is formed at each triangular apex of the cap removing portion 202. That is, a sharp cutting edge 203a is formed at the upper apex of the triangle, and a sharp cutting edge 203b is formed at the apexes on both sides of the lower part.

  Further, the cap remover 200 includes a handle portion 204 in a form as seen by a known driver or the like at the base end portion of the metal bar 201.

  FIG. 13B illustrates a cap removal operation using the cap remover 200. In order to remove the cap C fitted into the bottle B, the blade edge 203 of the cap remover 200 is inserted into the gap between the cap C and the bottle B at the lower end edge of the cap C (right side of the cap C in the drawing). Push and push up above bottle B (left side of paper).

  Thereby, the cap C can be cut and removed by the blade edge 203 of the cap remover 200. Further, even when the cap C cannot be completely cut, the cutting edge 203 can be cut into the inner peripheral surface of the cap C and the peripheral edge of the cap C can be pushed and widened. Can be peeled off.

Japanese Patent Laying-Open No. 2003-237892 (page 3-4, FIGS. 1 and 4) JP 2003-54693 A (page 3-4, FIGS. 2, 11)

  However, as in the prior art shown in FIG. 12 and FIG. 13, in the cap remover that lifts the outer lower edge of the cap and removes the cap, it is hard and sharp to securely hook the lower edge of the cap. It was necessary to provide a protrusion. That is, in the cap remover 100 shown in FIG. 12A, a locking portion 107 protruding in a substantially bowl shape is formed, and in the cap remover 200 shown in FIG. 13A, a sharp cutting edge 203 is formed. Has been.

  Therefore, with the cap remover of the prior art, there is a safety problem that sharply protruding protrusions (for example, the locking portion 107 and the blade edge 203) may come into contact with an operator or a nearby person and be injured. There was a point.

  In particular, since a force is required for removing the cap, for example, immediately after the cap is removed, the cap remover may be shaken greatly, which is very dangerous. Moreover, since the surface of the bottle is slippery and the lower end edge of the cap is thin, there is a risk that the sharp protrusion described above may come off the cap edge.

  In addition, since the cap remover of the prior art is provided with a hard and sharp protrusion as described above, if a force is applied too much, the glass bottle breaks, and as a result, the operator may be injured. There is also.

  Furthermore, in the cap remover 100 shown in FIG. 12, when removing the cap C, there is a risk that the finger holding the bottle B is pinched between the tip side oblique side 104 of the cap remover 100 and the bottle B. .

  This invention is made | formed in view of said situation, The place made into the objective provides the cap removal tool which can remove the cap fitted to the opening part of containers, such as a bottle, safely and easily. There is.

  A cap remover according to the present invention is a cap remover for removing a cap attached to an opening of a container to form a spout of the container from the container, and is inserted into the container from the spout. And a convex portion provided on the main body of the removal tool, and the cap is removed from the container by pushing up a part of the cap from the inside of the container by the convex portion. To do.

  According to the cap remover of the present invention, the remover body has a remover body and a convex portion provided on the remover body, and the remover body is inserted into the container from the spout formed on the cap. Since the cap is removed by applying the convex portion to the inside of the cap and pushing up the cap from the inside of the container, the cap can be removed from the container safely and easily.

  That is, the convex part is formed so as to contact a part on the inner surface side of the lid-shaped part formed so as to close the opening of the container and transmit a force in a direction facing the surface, that is, a direction of removing the cap. Has been. Therefore, the cap remover of the present invention does not have a hard and sharp protrusion as seen in the prior art cap remover, and can solve problems such as injury caused by the protrusion.

  Further, the cap remover of the present invention is formed so that the cross-sectional area of the convex portion is larger than the cross-sectional area of other portions of the remover main body. Can be brought closer to the periphery of the cap. As a result, it is possible to prevent the escape of force due to the deformation of the cap itself and the removal of the cap remover, efficiently transmit the force from the convex portion to the cap, and remove the cap by effectively using the force. it can. Here, the cross-sectional area is an area of a cross section that is substantially perpendicular to the extending direction of the cap remover, that is, the longitudinal direction.

  Further, according to the cap remover of the present invention, at least a part of the remover main body comes into contact with the cap from the outside of the container, and the convex part pushes up the cap from the inside of the container with the corresponding contact point as a fulcrum. By applying this principle, the cap can be easily removed with a small force.

  In addition, the cap remover according to the present invention is formed in a rod shape, and the remover main body is formed at least at one end of the rod-shaped body, so that it is easy to manufacture and is easy to handle and store during use. The cap can be easily removed with a small force.

  Hereinafter, a cap remover according to an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a front view showing a schematic structure of a cap remover 1 according to the first embodiment of the present invention. 2 to 5 are explanatory views showing a cap removing operation using the cap removing tool 1.

  As shown in FIG. 1, the cap remover 1 according to this embodiment includes an remover main body 2, a convex portion 3 provided on the remover main body 2, and a handle portion 4. The overall shape of the cap remover 1 is a substantially rod shape, and the remover main body 2 is formed at one end of the rod-shaped body, and the handle 4 is formed at the other end.

  The remover main body 2 has a rod-like shape with a circular cross section, and is a portion inserted into the inside of a container (for example, the bottle B shown in FIGS. 2 to 5) as will be described later. In addition, as a cross-sectional shape of the removal tool main body 2, arbitrary shapes, such as a polygon and an ellipse, can be employ | adopted, for example. The circular cross section is excellent in that it can be easily inserted into a container, exhibits sufficient strength in an arbitrary bending direction, and is easy to process.

  The convex part 3 is a bulging part provided in the vicinity of the distal end of the removal tool main body 2 and, as will be described later, abuts against the inner surface of a cap (for example, the cap C shown in FIGS. 2 to 5) and pushes up the cap. Part. The convex portion 3 according to the present embodiment has a substantially cylindrical shape, is formed coaxially with the removal tool main body 2, and has a larger cross-sectional circle diameter than the removal tool main body 2. That is, the convex portion 3 is formed so that the cross-sectional area of the portion is larger than the cross-sectional area of the removal tool body 2. In addition, the edge part of the convex part 3 is moderately rounded and chamfered.

  The handle portion 4 is a portion that holds the cap remover 1 when the cap is removed. As the handle 4, for example, an arbitrary shape such as the same shape as a known tool handle can be adopted. The handle portion 4 according to the present embodiment employs a cylindrical shape that is easy to process and handle and is excellent in strength.

  Here, the cap removal tool 1 according to the present embodiment is formed by integrally processing the whole using a single material. Specifically, synthetic resin is adopted as the material of the cap remover 1. Synthetic resins are easy to process and light in weight, so they are easy to handle. Further, the risk of damaging the glass bottle is reduced, which is advantageous in terms of safety.

  In this way, the synthetic resin material can be used because the cap remover 1 of the present invention employs a completely different removal method from the conventional one, as will be described later. This is because it does not require a hard and sharp protrusion as seen.

  In addition, it replaces with the integral shaping | molding method by the above-mentioned single material, processes the removal tool main body 2, the convex part 3, and the handle | pattern part 4 as separate parts, respectively, and joins them, The cap removal tool 1 is attached. You may assemble. Of course, different materials such as metal and resin can be used.

  Next, with reference to FIG. 2 thru | or FIG. 5, the usage method of the cap removal tool 1 which concerns on this embodiment is demonstrated. The drawings are shown in the order of work steps, and the work proceeds in order from FIG. 2 to FIG.

  As shown in FIG. 2, a cap C made of synthetic resin is fitted into the opening B1 of the bottle B (container). The bottle B is a container for containing, for example, soy sauce, dressing, yakiniku sauce, fruit juice and the like. And the cap C is for adjusting the taking-out flow rate of the contents appropriately, and there are some which are integrally provided with a lid for sealing the container.

  The cap C is formed with a substantially planar lid-like portion C2 so as to close the opening B1 of the bottle B. The lid portion C2 is formed with a spout C1 for taking out the contents such as soy sauce out of the bottle B. Although there are various shapes of the spout C1, the size of the spout C1 is sufficiently smaller than the opening B1 of the bottle B.

  In order to remove the cap C from the bottle B, first, the remover main body 2 provided with the projection 3 at the tip is inserted into the bottle B from the spout C1. In this operation, although not shown, the handle 4 of the cap remover 1 is held with one hand and the bottle B is held with the other hand.

  Next, as shown in FIG. 3, the handle 4 is moved downward (in the direction of arrow E) so that the entire cap remover 1 is rotated in the clockwise direction on the paper surface, and a part of the convex 3 is covered with the cap C. It is made to contact | abut to the inner side, ie, the lower surface, of the shaped part C2 (point L). At the same time, a part of the remover main body 2 is brought into contact with the upper edge of the cap C (point F).

  The cap remover 1 according to the present embodiment includes a convex portion 3 having a larger cross-sectional area than the remover main body 2 and bulging in the radial direction in the vicinity of the tip of the remover main body 2. The contact portion (point L) can be brought close to the outer periphery of the cap C. Therefore, the point of application of the force by the cap remover 1 (point L) can be brought close to the locking portion between the cap C and the bottle B. Thereby, a deformation | transformation of the cap C can be suppressed and force can be transmitted efficiently. Moreover, the danger that the cap removal tool 1 will remove | deviate during work can also be reduced.

  Here, as described above, since the convex portion 3 has a cylindrical shape formed coaxially with the removal tool main body 2, the contact position (L) between the convex portion 3 and the cap C is the axis described above. It does not depend on the rotation angle around Therefore, if the cap remover 1 according to the present embodiment is used, without worrying about the direction of the convex portion 3 (the rotation angle of the shaft center), that is, which side of the outer periphery of the convex portion 3 should be up. Work can be done efficiently.

  Next, as shown in FIG. 4, the protrusion 3 and the inner side of the cap C are brought into contact with each other at a point L, and the removal tool body 2 and the upper end edge of the cap C are brought into contact with each other at a point F. As shown by arrow E, the handle 4 is further pushed downward. That is, the cap remover 1 is moved so as to rotate clockwise with respect to the point F as a fulcrum. Thereby, the cap C is pushed up from the inner side of the bottle B by the convex portion 3, and the lock between the cap C and the bottle B is released.

  At this time, according to the cap remover 1 according to the present embodiment, the cap C is pushed up from the inside by the lever principle with the point F as a fulcrum and the point L as an action point, so that the cap C can be easily removed with a small force. be able to.

  Further, at point L, a force acts in a direction opposite to the inner surface of the cap-like portion C2 of the cap C from the convex portion 3, so that the cap remover 1 according to this embodiment is hard and sharp like the prior art. A force can be efficiently transmitted to the cap C without requiring a hooking portion.

  Further, since the force at which the convex portion 3 pushes the inner surface of the cap C at the point L is substantially upward, that is, the same direction as the direction in which the cap C is removed, the cap C can be removed using the force efficiently. .

  Then, the cap C can be removed from the bottle B as shown in FIG. Here, since the convex part 3 is formed so that the cross-sectional area is larger than the cross-sectional area of the removal tool body 2, it is possible to prevent the removed cap C from falling off the removal tool body 2. As described above, according to the cap remover 1 according to the present embodiment, the removed cap C remains in the remover main body 2, so that the efficiency of the removal work can be improved.

  As described above, the cap remover 1 according to the present embodiment removes the cap C from the bottle B safely and easily with a small force using the lever principle without having a hard and sharp protrusion or the like. be able to.

  Moreover, since the cap removal tool 1 which concerns on this embodiment does not require a hard and sharp protrusion, it can employ | adopt the resin material which is light and easy to handle. Moreover, since the whole is comprised with the single material, it is excellent also in the point that the decomposition | disassembly at the time of disposal is unnecessary.

  Next, as a modification of the embodiment of the present invention, cap removers 20, 30, 40, 50, 60, and 70 according to the second to seventh embodiments will be described in detail with reference to FIGS. . 6 to FIG. 11, the constituent elements having the same or similar functions and effects as the cap remover 1 according to the first embodiment described above are designated by the same numeral as the last digit of the reference numeral.
