Description

  The present invention relates to a pump container in which a container body including a pump device is accommodated in an outer case.

  As this type of pump container, conventionally, an outer container that contains a container for filling contents and a lid that seals the outer container are fixedly held via a base cap, and the contents filled in the container are sucked. In a container having a pump discharger that pressurizes and discharges from the tip nozzle of the nozzle head, the nozzle head is provided with a cover having an opening opened toward the lid, and the lid is opened toward the cover. A shoulder cover that has an opening and cooperates with the cover to form an internal space that surrounds the base cap is provided, and the shoulder cover is formed with a drain hole for discharging moisture that inevitably entered the internal space. Proposed.

  In the above pump container, the outer container has a structure that just houses the inner container, and the shoulder cover is separately configured so that the discharge head extending from the inner container can be moved relative to the outer container in the axial direction. However, a structure having a sliding portion between the shoulder cover and the upper end of the outer container is required, but it is complicated to configure such a shoulder cover that is integrally formed with the discharge head portion, Production costs also increase.

  In addition, these conventional pump containers can replace the inner container, and the outer container is configured for the purpose of completely closing the inner container and hiding its presence. Therefore, basically, a complicated structure for preventing the ingress of water into the inside is necessary, and no special consideration is given to the design.

Japanese Patent Laid-Open No. 2003-175988 JP 2003-192067 A

  Therefore, in view of the above situation, the present invention intends to solve the problem that the pump container in which the inner container (container body) is housed in the outer container (exterior case) increases the cost without requiring a complicated structure. It is the point which provides the pump container which can improve design property and functionality, suppressing it.

  In order to solve the above-mentioned problems, the present invention is a pump container comprising a container body that is accommodated in an exterior case and a pump device that discharges the contents in the container body. A sheet material having flexibility is formed into a cylindrical shape, and a plurality of slits extending in the longitudinal direction are formed in the peripheral wall of the outer case, and one end side of the outer case is protruded from the mouth of the container body. Connected to the discharge head of the pump device, the other end of the outer case is connected to the bottom of the container body, and responds to relative movement along the axial direction of the discharge head when operating the pump device. Each of the divided wall surfaces divided by the slits in the outer peripheral wall of the outer case is curved and deformed outward, whereby the outer case is stretched and deformed along the longitudinal direction. .

  Here, the slit is preferably formed by being twisted so as to be displaced in the circumferential direction along the longitudinal direction of the exterior case.

  Moreover, it is preferable that the slits are formed at equal intervals and the same length, and the divided wall surfaces divided by the slits have the same shape.

  Moreover, it is preferable that the upper and lower regions excluding the divided wall surfaces in the outer peripheral wall have a quadrangular shape, a polygonal shape, a circular shape, or an elliptical shape in sectional view.

  Further, it is preferable that the upper and lower regions excluding the divided wall surface in the outer case peripheral wall are configured to have a quadrangular or polygonal shape in cross section, and the plurality of slits are formed so as to tie the two-sided joint sides in the upper and lower regions vertically. .

  In particular, the container body preferably has a transparent or translucent peripheral wall.

  A connecting member for connecting the cylindrical case main body to the bottom of the container main body is provided at the end of the outer case.

  The outer case is preferably made of a resin-coated paper material.

  In the pump container according to the present invention as described above, each divided wall surface divided by the slit in the outer peripheral wall of the discharge case is curved and deformed outward in accordance with relative movement along the axial direction of the discharge head. Since the case is stretchable and deformed along the longitudinal direction, the internal container body can be seen from the outside when used through multiple slits while having a simple structure. In particular, the functionality of checking the remaining amount of contents can be improved.

  In addition, even if there is no transparent or semi-transparent part of the inner container body, by adopting a color and pattern different from the outer case, it can express excellent design with wide flexibility, depending on the size of the gap of the slit Since the amount that can be seen is determined, the extent to which the ejection head is pushed can be easily grasped by the way the container body is seen.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a longitudinal sectional view showing the overall configuration of a pump container 1 according to the present invention. FIGS. 1 to 4 are a first embodiment, FIG. 5 is a second embodiment, FIG. 6 is a third embodiment, and FIG. Shows the fourth embodiment, and FIG. 8 shows the fifth embodiment.

  As shown in FIGS. 1 and 2, the pump container 1 according to the present invention is provided with a pump device 4 that houses a container body 2 in an outer case 3 and discharges contents in the container body 2. The outer case 3 is formed in a cylindrical shape from a flexible sheet material, and a plurality of slits 31 extending in the longitudinal direction are formed in the peripheral wall 30. One end side 3 a of the outer case 3 is connected to the discharge head 41 of the pump device 4 protruding from the mouth portion 20 of the container body 2, and the other end side 3 b is connected to the bottom portion 21 of the container body 2. .

  FIG. 2 shows a state in which the discharge head 41 has extended with respect to the container body 2, and FIG. 3 shows a state in which the discharge head 41 has been pushed in. In the pump container 1, each of the divided wall surfaces 32 divided by the slits 31 in the outer peripheral wall 30 of the outer casing 30 in accordance with the relative movement along the axial direction of the discharge head 41 when the pump device 4 is operated is outward. As a result, the outer case is expanded and contracted along the longitudinal direction.

  First, based on FIGS. 1-4, 1st Embodiment of this invention is described.

  The outer case 3 that accommodates the container body 2 is configured by assembling a paper material with a resin coat (resin film layer) into a cylindrical shape, and is not easily broken even if moisture or the like adheres while having flexibility. It has durability. In addition to paper materials, other materials such as sheet-like synthetic resin materials can also be used, but by using paper materials, artificial images are wiped out and images of natural softness and warmth are created. Making it possible.

  Each slit 31 that enables the outer case 3 to be stretchable and deformed in the longitudinal direction is formed by being twisted so as to be displaced in the circumferential direction. Specifically, slits 31 (through slits) extending obliquely with respect to the axial direction are formed in the mount 36 before assembly shown in FIG. 4, and this is assembled into a cylindrical shape, which is shown in FIGS. Such twisted slits 31 are formed. In this example, the slit 31 is formed by forming the cut through the slit. However, the slit 31 may be formed by forming a wider through groove.

  These slits 31 are formed in the middle in the longitudinal direction of the peripheral wall 30 of the outer case 3, and more specifically, the upper and lower regions of the outer case where the slits 31 do not exist are configured as squares in cross section, and the slits 31 are in between. Divided wall surfaces 32,... Of the same shape are formed at equal intervals in the circumferential direction and divided by the slits 31.

  In addition, it is also preferable not to provide the slit 31 only in the middle part in the longitudinal direction but to extend to one end or both ends in the longitudinal direction. However, when the slit is extended to the end as described above, a connecting member for bundling the divided wall surfaces divided by the slit is necessary.

  It is also possible to form the slits 31 at different intervals to form divided wall surfaces having different sizes and shapes. However, in this case, it is preferable that at least the difference in the size and shape of each divided wall surface is regularly repeated in the circumferential direction so that the expansion and contraction of the outer case is along the axial direction. Furthermore, the length of the slit 31 may be different. Also in this case, for the same reason, it is preferable that the difference in length of each slit 31 has regular repetition in the outer casing circumferential direction.

  In this example, as shown in FIGS. 2 to 4, the upper and lower regions of the outer peripheral wall of the outer case are configured in a square shape in cross section, and the plurality of slits 31 are formed so as to connect the two-sided joint sides 33 and 34 in the upper and lower regions vertically. By being formed, each of the divided divided wall surfaces 32 can be smoothly deformed outward. In addition, the cross-sectional shape of the upper and lower regions excluding the divided wall surface 32 can be configured in a long direction, a parallelogram, a polygon, a circle, an ellipse, and other appropriate shapes other than a square. Of course, a combination of different shapes such as one having a circular shape and the other having a polygonal shape is possible.

  The container main body 2 accommodated in the exterior case 3 is configured such that the peripheral wall portion 22 is transparent or translucent and the remaining amount of contents can be seen from the outside through the peripheral wall portion 22. As shown in FIG. 3, the peripheral wall portion 22 pushes the discharge head 41, shrinks the outer case 3 in the axial direction, and the divided wall surfaces 32 between the slits 31 are curved and deformed outward. It can be seen from the outside through the gap of ..., and the user can easily check the remaining amount of the contents while using it.

  In addition, the whole peripheral wall part 22 of this container main body 2 does not need to be transparent or semi-transparent, and may be a part. Moreover, even if there is no transparent or semi-transparent part, by adopting a different color and pattern from the exterior case, it is possible to express excellent design, as well as the amount that can be seen depending on the size of the gap of the slit 31 Therefore, the extent to which the ejection head is pushed can be easily grasped by the appearance of the peripheral wall portion 22. In this example, the peripheral wall portion 22 is circular and transparent in cross section, but the shape is not particularly limited.

  A known inverted pump device can be used as the pump device 4 that discharges the contents in the container body 2. In this example, as shown in FIG. 1, a cylinder 43 in which a piston 42 for sucking and discharging contents is inserted, a discharge head 41 having a discharge port 40 connected to the piston 42, and a cylinder 43 are provided. A ball valve 44, a flexible suction pipe 45 with a weight connected to the suction portion of the cylinder 43, and a mounting cap 46 for mounting these devices on the mouth portion 20 of the container body 2. Yes.

  In this example, the discharge head 41 has a dish shape, and the contents are discharged into the discharge head 41 from the discharge port 40 in the center. However, other discharge modes can of course be employed. A discharge nozzle that extends laterally by penetrating the peripheral wall 30 of the case may be provided. In this case, the pump container 1 may be used by placing it on the floor with the container body mouth portion 20 provided with the pump device 4 as the upper side and the connecting member 35 as the lower side.

  As the contents filled in the container body 2, various liquids such as shampoos, rinses, body soaps, hair treatments, cosmetics, hair styling agents, drugs, detergents, etc. can be adopted depending on the use of the pump container. The pump device 4 can also constitute a pump device that mixes gas with the liquid of the contents and discharges it in the form of bubbles, or a pump device that discharges liquid as it is, depending on the application.

  A connecting member 35 that fixes the bottom 21 of the container body 2 and connects it to the exterior case 3 is attached to the inner peripheral surface of the other end side 3b of the exterior case. For example, in a state where the pump container 1 is stood with the discharge head 41 facing down on one palm, the container body 2 moves downward together with the connection member 3 by pressing the outer surface of the connection member 35 from above. 41 is relatively pushed into the pump container, and the contents are discharged onto the palm.

  In the present embodiment, the slit 31 is twisted so as to be displaced in the circumferential direction, so that both end portions of the outer case rotate relative to each other during expansion and contraction. In the case of FIG. 2, the divided wall surfaces 32 are curved outward by pressing the connecting member 35 while rotating it slightly clockwise in plan view, and the exterior case can be shrunk without any sense of resistance. However, the connecting member 35 may constitute a pressing portion that is rotatable about the axis.

  The discharge head 41 may be provided with a cap that is attached when not in use. In addition, when the pump is not in use, the discharge head 41 needs to be pushed into the container body 2 so that the pump device 4 does not move. However, in the present invention, since the divided wall surface 32 divided by the slit 31 is configured to be stretchable by protruding to the outside, a restricting member for preventing the protruding to the outside, such as a film, is provided. It may be provided around the slit 31 to restrict the deformation of the divided wall surface 32, and the film or the like may be peeled off during use.

  Hereinafter, based on FIGS. 5-8, 2nd-5th embodiment is described as a modification of the form of an exterior case or the form of a slit. In addition, in each embodiment, the same code | symbol is attached | subjected about the structure similar to 1st Embodiment, and the description is abbreviate | omitted. Further, the deformation pattern of each part is basically the same as that of the first embodiment, and the description thereof is omitted.

  FIG. 5 shows a second embodiment in which the exterior case has a polygonal shape in plan view. Even in this polygonal shape, the slit 31 on the outer peripheral wall is formed so as to tie the two-sided joint sides 33 and 34 in the upper and lower regions vertically as in the first embodiment. In this way, the number of slits 31 is greater than that of the square in plan view of the first embodiment, and the width of the divided wall surface 32 formed therebetween is narrowed. The bending deformation to the direction becomes easy. That is, a softer operational feeling can be obtained by providing many divided wall surfaces 32 that are relatively easily deformed. Further, since the number of slits 31 is increased, there is also an advantage that when the discharge head 41 is pushed in, it is easy to visually recognize the inner container body 2 through each slit 31.

  FIG. 6 shows a third embodiment in which the slits 31 are not twisted so as to be displaced in the circumferential direction, but are formed straight without being displaced. If such a slit 31 is adopted, when the discharge head is pushed in, the entire end case does not rotate (without twisting) with respect to the other end side, so that the straightforward operation can be performed. Is possible.

  FIG. 7 shows a fourth embodiment in which the outer case is circular in plan view. If such a circle or ellipse is adopted, there are no two-sided joint sides in the upper and lower regions of the outer case, and the design can be freely performed without obstructing the expansion / contraction operation no matter where the slit 31 is formed. The degree is improved.

  FIG. 8 shows a fifth embodiment in which both ends of the exterior case have different sizes. Even if the sizes are different in this way, the expansion and contraction by the slits 31 is not hindered, and a product having excellent stability and design at the time of use can be obtained.

  As mentioned above, although each embodiment of this invention was described, this invention is not limited to such an Example at all, Of course, it can implement with a various form in the range which does not deviate from the summary of this invention.
