As described above, the projecting wall portion 360 is supported above the area between the index finger and the thumb. Therefore, the smaller the length H1 in the vertical direction from the lower end of the trigger lever 24 to the projecting wall portion 360 is, the lower the position of the user's hand becomes. That is, how the user's finger is caught on the trigger lever 24 changes depending on the length H1. For example, if the length H1 is too small, only one user's finger will be caught on the trigger lever 24, and if the length H1 is too large, the user's finger will only hit near the base of the trigger lever 24.

From this point of view, it is desirable that the length H1 is 20 mm or more. According to this configuration, the user can hook two or more fingers on the trigger lever 24, so it is possible to reduce the load on each finger when pulling the trigger lever.

Further, the length H1 is desirably 55 mm or less, particularly preferably 40 mm or less. According to this configuration, the lowermost finger of the plurality of fingers of the user that hits the trigger lever 24 can hit the lower end of the trigger lever 24 . That is, the point of force may be located farthest from the fulcrum S on the trigger lever 24. In this case, according to the principle of leverage, the user can pull the trigger lever 24 with less force.

As described above, the exterior body 30 is gripped so that the part between the index finger and the thumb touches the upright wall part 350. Therefore, the ease with which the trigger lever 24 is pulled changes depending on the length L1 in the front-rear direction from the front end of the trigger lever 24 to the upright wall portion 350. For example, if the length L1 is too large, only the tip of the user's finger will be caught on the trigger lever 24, making it difficult to apply force when pulling the trigger lever 24, and if the length L1 is too small, it will be difficult to pull the trigger lever 24. It becomes difficult.

From this point of view, it is desirable that the length L1 is 60 mm or more and 80 mm or less. According to this configuration, the user can easily apply force when pulling the trigger lever 24, and can easily pull the trigger lever 24 completely.

(Length L2)
As described above, the projecting wall portion 360 is supported above the area between the index finger and the thumb. Therefore, the stability when the user grips the container 1 changes depending on the length L2 from the rear end of the projecting wall portion 360 to the flat region 352. For example, if the length L2 is too short, the contact area between the upper part of the index finger and the thumb and the overhanging wall part 360 will be insufficient, resulting in low grip stability.

From this point of view, it is desirable that the length L2 is 20 mm or more. According to this configuration, a sufficient contact area between the upper part of the interdigital part of the index finger and the thumb and the protruding wall part 360 is ensured, so it is possible to realize stable gripping.

<Modified example>
Next, the configuration of the exterior body 40 according to a modified example will be explained.

FIG. 5 is an explanatory diagram showing a side view of the trigger type discharge device 20 and the exterior body 40 according to a modified example. As shown in FIG. 5, the exterior body 40 includes an upper wall 410, a pair of side walls 420, a rear wall 430, an upright wall portion 450, and an overhanging wall portion 460.

The main difference between the exterior body 40 according to the modification and the exterior body 30 described above is that the length of the rear wall 430 and the length of the rising wall portion 450 in the vertical direction of the exterior body 40 according to the modification are different from the exterior body 30 described above. The length of the rear wall 330 and the length of the upright wall portion 350 in the vertical direction of 30 are different from each other. Specifically, the length of the rear wall 430 in the vertical direction of the exterior body 40 according to the modified example is smaller than the length of the rear wall 330 of the exterior body 30, and the length of the upright wall portion 450 in the vertical direction of the exterior body 40 according to the modified example The length is greater than the length of the rising wall portion 350 of the exterior body 30.

That is, the length H2 from the lower end of the cap 22 to the overhanging wall portion 460 in the exterior body 40 according to the modified example is greater than the length from the lower end of the cap 22 to the overhanging wall portion 360 in the exterior body 30. A length H2 from the lower end of the cap 22 to the overhanging wall portion 460 in the exterior body 40 is longer than the length of the overhanging wall portion 460. It is desirable that this length H2 is 35 mm or more.

According to this configuration, even when the trigger-type discharger 20 and the exterior body 40 are attached to the container body 14 as shown in FIG. 6, for example, the user can firmly grasp the trigger-type discharger 20 and the exterior body 40. Is possible. Specifically, the container main body 14 has a neck part 12, a body part 16 consisting of a cylindrical part 16a, a bottom part 16b, and a shoulder part 16c. It protrudes along a direction closer to the radial direction perpendicular to the up-down direction than the up-down direction, which is the axial direction. Here, in the exterior body 40 according to the modified example, since the length H2 from the lower end of the cap 22 to the overhanging wall portion 460 is sufficiently secured, the user can It is possible to grasp the container by inserting a hand between them. That is, according to the modified example, the advantage is obtained that the user can easily grip the container regardless of the shape of the container body to which the trigger type discharger 20 and the exterior body 40 are attached.

Moreover, in the exterior body 40 according to the modified example, the surface of the trigger lever 24 that is operated by the user's finger has a curved shape that is convex toward the user's finger. According to this configuration, when the user pulls the trigger lever 24, each finger of the user is easily separated, so that it is easy to maintain a state in which a wide range of the trigger lever 24 is gripped.
