A packaging bag is disclosed.

Japanese Patent No. 4856412 JP-A-2004-269010

  However, in the conventional packaging bag, the fingers are tightened or the hands are hurt at the time of carrying, depending on the weight and bulk of the packaged object stored in the packaging bag, the way of holding the packaging bag in which the packaged object is stored, and the like. May be. Also, when carrying the packaging bag, the handle may be stretched or broken. For this reason, the packaging bag may be difficult to hold while the packaged object is stored, and the packaging bag may be damaged when being carried.

  An object of the present invention is to provide a packaging bag which is easy to hold and is not easily damaged.

  According to a first aspect of the present invention, there is provided a main body for accommodating an object to be packaged, a handle provided on an upper portion of the main body, and a finger hook formed at a longitudinal central portion of the handle. And a cushioning member containing a gel-like substance is formed at least above the finger hook.

  In this specification, a gel-like substance is a solid substance in which a viscous colloid solution has lost fluidity in a stationary state. The form of the gel-like substance is not particularly limited, and the substance whose fluidity does not change (does not generate fluidity) due to physical stimulus (pressurization, temperature change, etc.) and the substance whose fluidity changes due to physical stimulus (fluidity) ), Which include any of the following: Examples of the gel-like substance whose fluidity changes due to physical stimulus include those having heat solubility and those having thixotropic properties described later.

  In addition, the cushioning member is applied to a finger or the like when a finger or a palm (hereinafter, referred to as a finger or the like) is inserted into a finger hook and the handle is grasped (or grasped) in a state provided in the packaging bag. It is a member that relieves (or relieves) pressure (or load). The form of the cushioning member containing the gel-like substance is not particularly limited. For example, the form in which the gel-like substance contained in the cushioning member is formed in a sheet shape, and a film sheet attached to the surface of the handle portion may be used. Examples thereof include those interposed therebetween, and those in which a gel material is filled in a film bag.

  Further, that the buffer member is formed at least above the finger hook is not limited to the case where the buffer member is formed only above the finger hook, but the entire handle including the above the finger hook is Alternatively, it indicates that a buffer member may be formed partially.

  In the first aspect, since such a cushioning member is formed at least above the finger hook, the buffer member is provided above the finger hook when a finger or the like is inserted and the handle is grasped (or grasped). The buffer member can be grasped. Further, since the buffer member contains a gel-like substance, the pressure applied to a finger or the like when grasping the handle portion is distributed to the buffer member.

  Further, the shape of the buffer member containing the gel-like substance changes in accordance with the state of the finger or the like holding the handle. In other words, the cushioning member containing the gel-like substance hits (fits) a finger or the like that has grasped (or grasped) the handle. Therefore, the handle portion provided with at least the buffer member including the gel-like substance can be grasped (or grasped) in a stable state.

  With such a configuration, in the first mode, the load applied to the finger or the like when the handle is gripped can be reduced (or reduced). Therefore, it is possible to prevent the finger or the like from being tightened by the handle portion or the finger or the like from being hurt. Thereby, in the first aspect, the handle portion is easily grasped, and the carrying of the packaging bag is facilitated.

  Further, in the first aspect, the pressure applied to the finger or the like is dispersed by the buffer member containing the gel-like substance as described above, and the handle portion can be gripped in a stable state. Elongation and breakage can be suppressed. Therefore, when carrying the packaging bag in a state where the packaged object is stored, the packaging bag is less likely to be damaged.

  A second aspect according to the present invention provides a packaging bag, wherein the gel-like substance has thixotropic properties. In the present specification, the thixotropic property indicates a property in which the viscosity (or viscosity) decreases when a certain force is applied, and returns to the original viscosity when the force is not applied (stand still) (hereinafter, referred to as thixotropic property). In some cases).

  In the second aspect, since the gel substance contained in the buffer member has thixotropic properties, the buffer member containing the gel substance can absorb the pressure applied to the finger or the like while dispersing it. Further, in the case of the cushioning member containing a gel-like substance having thixotropic properties, the shape is more likely to change in accordance with the finger or the like holding the handle. Therefore, the hand can be touched (or fitted) with a finger or the like grasping the handle, so that the handle can be gripped in a more stable state.

  A third aspect according to the present invention provides a packaging bag, wherein the buffer member is a film bag body filled with the gel-like substance. In the third aspect, by using such a film bag filled with a gel substance as the buffer member containing the gel substance, the configuration of the buffer member containing the gel substance can be simplified. .

  In addition, since the buffer member in which the gel material is filled in such a film bag body is given shape retention, when the handle portion is gripped, the portion of the handle portion where the buffer member is provided is reduced. , It becomes easier to hit the finger or the like in a planar manner. In other words, the portion of the cushioning member provided on the handle portion is unlikely to hit the finger or the like in a linear manner.

  With such a configuration, when a finger or the like is applied to the finger hook and the handle is grasped, the pressure applied to the finger or the like is further dispersed to the cushioning member provided in the handle, and the hand is grasped. In this case, the load on the fingers and the like can be further reduced. Therefore, it is possible to further suppress the finger or the like being tightened by the holding portion or the pain of the finger or the like. Thereby, in the third aspect, the handle portion is further easily grasped, and the carrying of the packaging bag is facilitated.

  A fourth aspect according to the present invention provides a packaging bag in which the film bag is attached in a thickness direction of the handle. In the fourth aspect, the buffer member containing the gel-like substance can be provided on the handle simply by sticking the film bag filled with the gel-like substance in the thickness direction of the handle. Therefore, in the fourth aspect, a buffer member containing a gel-like substance can be easily provided on the handle.

  In a fifth aspect according to the present invention, the finger hook is formed by a slit extending along the longitudinal direction, and a central portion of the finger hook is curved downward in a height direction of the handle. Provide packaging bags.

  In this specification, extending along the longitudinal direction includes both cases where the slit is parallel to the longitudinal direction of the handle portion and cases where the slit is not parallel. The shape of the slit is not particularly limited, and may be any of a straight line, a curved line, a wavy line, and the like. In addition, “curved downward in the height direction of the handle” indicates that the center of the finger hook is bent in a convex shape toward the lower end of the handle.

  In the fifth aspect, by forming the finger hook portion with such a curved slit, the finger hook portion can be configured according to the shape of a finger or the like to be put into the finger hook portion. Therefore, it is possible to easily put a finger or the like on the handle by simply putting the finger or the like in the thickness direction of the handle through the slit.

  In a sixth aspect according to the present invention, the finger hook has an inflection point between a center portion of the finger hook and both ends of the finger hook, and each tip of the both ends is Provided is a packaging bag wherein the both ends are curved so as to be located below each of the inflection points.

  In this specification, the inflection point is located between the center of the finger hook formed by the slit and the two ends, and indicates a point at which the bending direction of the finger hook changes (bending point). Further, when both ends of the finger hook are curved so that the respective ends of the both ends of the finger hook are located below the respective inflection points, it means that each end of the finger hook is in the longitudinal direction of the handle. It is shown that it extends from each inflection point to each tip from the inflection point continuously to the center of the finger hook portion, while bending convexly from the central portion toward each end of the handle portion.

  In the sixth aspect, both ends of the finger hook are curved so that the tips of both ends of the finger hook are located below each inflection point of the finger hook, so that the finger or the like can be used as the finger hook. When the handle portion is inserted and grasped (gripped), a part of the handle portion (bent portion) that bends while being connected to the handle portion can be bent below the finger hook portion. That is, it is possible to prevent a part (bent portion) of the handle portion from rolling up above the finger hook portion.

  With such a configuration, when a finger or the like is put into the finger hook and the handle is grasped, a part (bent portion) of the handle is sandwiched between the finger or the like and the cushioning member of the handle. Can be prevented. Thereby, in the sixth aspect, even when the center of the finger hook formed by the slit curves downward in the height direction of the handle, when the handle is gripped, The finger hook portion can be configured so that the cushioning member of the handle portion surely hits it.

  In addition, a part of the handle part (bent part) bent downward in a state of being connected to the handle part, when a finger or the like is put into the finger hook part and the hand part is grasped (or grasped), It is easy to hit a finger or the like in a plane (it is hard to hit a line). In the sixth aspect, from such a viewpoint, it is possible to suppress the pain of the fingers and the like.

  According to a seventh aspect of the present invention, there is provided a packaging bag, wherein the cushioning member is arranged at a center of the handle in a height direction. In this specification, the central portion in the height direction of the handle portion indicates a region including the center in the height direction of the handle portion and the vicinity or periphery of the center.

  In the seventh aspect, the buffer portion is arranged at the center in the height direction of such a handle portion, so that the finger hook portion is formed near the lower end of the handle portion. In addition, the handle portion tends to be easily cut toward the upper portion of the finger portion, but in the seventh mode, the finger portion is formed near the lower end of the handle portion, so that the margin of the handle portion is reduced. Since (the portion where the handle portion is not formed) exists sufficiently (or in a wide range) above the finger hook portion, it is difficult for the handle portion to break from the finger hook portion toward the upper end of the handle portion. You can stop it.

  An eighth aspect according to the present invention provides a packaging bag, wherein the finger hook and the cushioning member are surrounded by a seal formed on the handle. The seal portion can be a reinforcing portion for reinforcing the handle portion in the packaging bag. Therefore, the finger hook portion formed on the handle portion is surrounded by the seal portion (reinforcement portion) with the cushioning member provided above. In the eighth aspect, by surrounding the finger hook portion with such a seal portion, it is possible to further prevent the handle portion from being broken starting from the finger hook portion.

Thus, the finger hook 30 and the cushioning member 40 are surrounded by a part of the side end seals 53 and 54 and the intermediate seal 55.

  7 to 9 are views showing a usage mode of the packaging bag 100 according to the present embodiment. Here, the effects of the present embodiment will be described with reference to FIGS. In the present embodiment, first, a finger P or the like can be put into a finger hook 30 formed in the central portion 25 of the handle portion 20 in the longitudinal direction (X direction) (see FIGS. 7 and 8).

  In the present embodiment, the buffer member 40 including the gel-like substance 42 is formed above the finger hook 30 as described above. Therefore, when a finger P or the like is inserted into the finger hook 30 and the grip 20 is gripped (or gripped), the buffer member 40 provided above the finger hook 30 can be gripped. In addition, since the buffer member 40 includes the gel-like substance 42, the pressure applied to the finger P or the like when the gripper 20 is grasped is dispersed to the buffer member 40.

  In addition, the shape of the buffer member 40 including the gel-like substance 42 can be changed according to the state of the finger P or the like holding the handle 20. In other words, the cushioning member 40 including the gel-like substance 42 can be applied in a form adapted to a finger P or the like gripping (or gripping) the handle portion 20. (Fit). Therefore, the handle portion 20 provided with the buffer member 40 including the gel-like substance 42 provided above can be grasped (or grasped) in a stable state.

  With such a configuration, in the present embodiment, the load applied to the finger P or the like when the handle portion 20 is grasped can be reduced (or reduced). For this reason, it is possible to prevent the finger P or the like from being tightened by the handle portion 20 or to hurt the finger P or the like. Thus, in the present embodiment, the handle portion 20 is easily grasped, and the carrying of the packaging bag 100 is facilitated.

  Further, in this embodiment, the pressure applied to the finger or the like P is dispersed by the buffer member 40 including the gel-like substance 42 as described above, and the holding portion 20 can be gripped in a stable state, thereby The extension and breakage of the hand portion 20 can be suppressed. Therefore, when carrying the packaging bag 100 in a state where the packaged object T is accommodated, the packaging bag 100 is less likely to be damaged.

  Further, in the present embodiment, since the gel-like substance 42 contained in the cushioning member 40 has the thixotropic property as described above, the buffering member 40 containing the gel-like substance 42 disperses the pressure applied to the finger P or the like. Can be absorbed. Further, in the cushioning member 40 including the gel-like substance 42 having thixotropic properties, the shape is more likely to change in accordance with the finger or the like P gripping the handle portion 20, and the buffer member 40 fits in with the finger or the like P gripping the handle portion 20. (Or fit), the handle 20 can be gripped in a more stable state.

  In addition, in the present embodiment, since the cellulose fibers are included in the buffer member 40 as the gel-like substance 42 having thixotropic properties, the buffer member 40 including the gel-like substance 42 disperses the pressure applied to the finger P or the like. It can be further absorbed. Further, in the cushioning member 40 including the cellulose fiber, the shape is further easily changed in accordance with the finger P or the like holding the handle portion 20. Accordingly, the cushioning member 40 is further adapted (or fitted) to the finger or the like P gripping the handle portion 20, so that the handle portion 20 can be gripped in a more stable state.

  Further, in the present embodiment, the buffer member 40 is formed by filling the gel-like substance 42 into the film bag 41 as described above, and the buffer member 40 thus configured is provided with shape retention. . Therefore, when the handle portion 20 is grasped, the portion of the handle portion 20 where the cushioning member 40 is provided can easily hit the finger P or the like in a planar manner. In other words, the portion of the cushioning member 40 provided on the handle portion 20 is unlikely to linearly hit the finger P or the like.

  With such a configuration, in the present embodiment, when the finger or the like P is applied to the finger hook 30 and the handle 20 is grasped, the pressure applied to the finger or the like P is further increased by the cushioning member provided on the handle 20. The load applied to fingers P when gripping the handle portion 20 can be further reduced. For this reason, it is possible to further suppress the finger or the like P being tightened by the handle part 20 or the finger or the like P becoming painful. Thus, in the present embodiment, the handle portion 20 is further easily grasped, and the carrying of the packaging bag 100 is further facilitated.

  In the case where the cushioning member 40 is provided with shape retention, it is not limited to the case where the cushioning member 40 is formed by filling the film bag 41 with the gel-like substance 42. For example, the gel-like substance 42 may be formed in a sheet shape or a film sheet (such as the above-described reinforcing film) attached to the surface (one surface 20A and / or the other surface 20B) of the handle 20. Even when a gel-like substance 42 is interposed between the fingers or the like, it is possible to impart shape retention to the cushioning member 40 (the portion of the handle 20 where the cushioning member 40 is provided is planar with respect to the finger P or the like). Easier to hit).

  In the present embodiment, the cushioning member 40 in which the gel-like substance 42 is filled in the film bag 41 as described above is attached only in the thickness direction (Z-direction) of the handle 20, and the gel-like substance 42 is formed. Can be provided on the handle portion 20. Therefore, in the present embodiment, the buffer member 40 including the gel-like substance 42 can be easily provided on the handle portion 20.

  In addition, although the handle part 20 tends to be cut easily above the finger part 30, in the present embodiment, the finger part 30 is formed near the lower end 21 of the handle part 20 as described above. Since the margin of the handle portion 20 (the portion where the handle portion 20 is not formed) is sufficiently (or in a wide range) above the finger hook portion 30 by the presence of the Breaking of the handle 20 toward the upper end 22 of the handle 20 can be prevented.

  In the present embodiment, as described above, the finger hook 30 and the cushioning member 40 are surrounded by the seal portion 50 (a part of the upper end seal 51, a part of the lower end seal 52, and the side end seals 53 and 54). ing. An intermediate seal 55 is formed above the cushioning member 40, and is provided between the upper end 22 (or the upper end seal 51) of the handle 20 and the cushioning member 40. Thus, the finger hook 30 and the cushioning member 40 are surrounded by a part of the side end seals 53 and 54 and the intermediate seal 55.

  Since such a seal portion 50 can be a reinforcing portion for reinforcing the handle portion, the finger hook portion 30 formed on the handle portion 20 has such a seal in a state where the cushioning member 40 is provided above. The configuration is surrounded by the portion 50 (reinforcement portion). Thus, in the present embodiment, it is possible to reliably prevent the handle portion 20 from being broken starting from the finger hook portion 30 in the central portion 25 in the longitudinal direction (X direction) of the handle portion 20.

  FIG. 10 shows the handle 20 of the packaging bag 100 according to the present embodiment (second embodiment).

The lower part 30 can be bent. That is, it is possible to prevent a part (bent portion) of the handle portion 20 from being turned up above the finger hook portion 30.

  With such a configuration, when the finger or the like P is put into the finger hook 30 and the handle 20 is grasped, a part (bent portion) of the handle 20 is buffered between the finger or the like P and the handle 20. It can be prevented from being caught between the member 40. Thereby, in the present embodiment, even when the central portion 31 of the finger hook portion 30 formed by the slit S curves downward in the height direction (Y direction) of the handle portion 20, the handle portion 20 is grasped. At this time, the finger hook portion 30 can be configured so that the buffer member 40 of the handle portion 20 reliably hits the finger P or the like.

  In addition, a part (bent portion) of the handle portion 20 that is bent downward in a state of being connected to the handle portion 20 grasps (or grips) the handle portion 20 by inserting a finger P or the like into the finger hook portion 30. At the same time), it is easy to hit the finger P or the like in a planar manner (it is hard to hit the finger). In the present embodiment, from such a viewpoint, it is possible to suppress the pain of the fingers and the like.
