Description

[Technical Field]

[0001] The present invention relates to a paper container with a discharge pump, and particularly to a container for use on a washstand, in a bathroom, etc. [Background technology]

[0002] A known example of this type of paper container with a discharge pump is one that has a nozzle head push-down type discharger attached to the neck opening that rises from the center of the top plate of a square cylindrical container body made of paper (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2019-99266 Summary of the Invention [Problem to be solved by the invention]

[0004] In the container of Patent Document 1, when the nozzle head is pressed down, stress is concentrated near the neck, causing the top plate to deform, which can make the dispenser unstable or cause the inner periphery of the top plate to bend and cave in. Furthermore, if the top plate caves in, water can accumulate there, and the moisture can weaken the paper material.

[0005] The first object of the present invention is to provide a paper container with a discharge pump that can suppress deformation near the top plate of the container body, and the second object of the present invention is to prevent the top of the container body from being weakened by moisture. [Means for solving the problem]

[0006] First, the basic configuration of the present invention will be described. The basic configuration is: A container body 2 formed as a paper container, having a substantially flat top plate 6 attached to an upper end 5 of a body peripheral wall 4 and a neck portion 8 erected therefrom; a pump-type dispenser 40 provided with a mounting tube 47 around a cylinder 42 mounted on the upper side of the mouth and neck portion 8 for mounting the cylinder to the mouth and neck portion 8 side so that the cylinder cannot be removed upward, and a head portion 56 having a discharge port 58 communicating with the inside of the cylinder 42, the dispenser 40 being actuated by pressing down the head portion 56; At least a part of the cylinder 42 is embraced by an outer peripheral wall 18, and a joint member 10 having a lower joint part 12 connected to the mouth and neck part 8 on the lower side of the outer peripheral wall 18 and an upper joint part A connected to the mounting tube 47 on the upper side of the outer peripheral wall 18. Equipped with The joint member 10 has a support means 22 that projects from the outer peripheral wall 18 toward the upper surface 7 of the top plate 6 and is supported by the upper end 5 of the body peripheral wall 4.

[0007] The basic configuration As shown in Figures 2 and 4, the container comprises a container body 2 which is a paper container with a mouth and neck portion 8 standing upright from a top plate 6, a pump-type dispenser 40 which is provided with an attachment tube 47 around a cylinder 42 mounted on the upper side of the mouth and neck portion 8 for attaching (connecting) to the mouth and neck portion 8 side, and a joint member 10 which connects to the mouth and neck portion 8 at the lower side of an outer peripheral wall 18 which embraces the cylinder 42 and to the attachment tube 47 at the upper side of the outer peripheral wall 18. The joint member 10 has a support means 22 that projects from the outer peripheral wall 18 toward the upper surface 7 of the top plate 6 and is supported by the upper end 5 of the body peripheral wall 4 of the container body 2. According to this structure, the load from the dispenser 40 is distributed to the body circumferential wall 4, so that deformation of the top plate 6 of the container body 2 (particularly depression on the inner circumferential side) can be suppressed. This allows the dispenser 40 to be stably supported, and also reduces the possibility of water collecting in the recess on the inner periphery of the top plate 6 and weakening the top plate 6 due to moisture.

[0008] No. 1 The means of The basic configurationThe support means 22 has a peripheral abutment surface T that surrounds the mouth and neck portion 8, and is installed on the top plate 6 via this peripheral abutment surface T, and the peripheral abutment surface T is placed on the upper end 5 of the barrel peripheral wall 4 at multiple support points A in the circumferential direction of the barrel peripheral wall 4.

[0009] In this means, as shown in Figures 2 and 4, the support means 22 is installed on the top plate 6 via a circumferential abutment surface T that surrounds the mouth and neck portion 8, and the circumferential abutment surface T is placed on the upper end 5 of the barrel peripheral wall 4 at multiple support points A in the circumferential direction of the barrel peripheral wall 4. According to this structure, the load from the dispenser 40 is distributed to the top plate 6 and the body peripheral wall 4 via the circumferential abutment surface T, and stress does not concentrate on the inner peripheral portion of the top plate adjacent to the neck portion as in the prior art, thereby further reducing deformation of the top plate 6.

[0010] No. 2 The means of The basic configuration The support means 22 has a support cylindrical portion 26 suspended from the outer surface of the outer peripheral wall 18, and a ring-shaped outward flange 28 extending from the lower end of the support cylindrical portion 26 along the upper surface 7 of the top plate 6, and the outward flange 28 reaches the upper end 5 of the cylindrical wall 4 at a plurality of support points A in the circumferential direction of the cylindrical wall 4.

[0011] In this means, as shown in Figure 2, the support means 22 has a support cylindrical portion 26 hanging down from the outer surface of the outer peripheral wall 18, and a ring-shaped outward flange 28 extending from the lower end of this support cylindrical portion 26 along the upper surface 7 of the top plate 6, and the outward flange 28 reaches the upper end 5 of the cylindrical peripheral wall 4 at multiple support points A around the circumferential direction of the cylindrical peripheral wall 4. According to this structure, the inner periphery of the top plate 6 is covered by the outward flange 28, which reduces the possibility that the inner periphery will come into contact with water and be weakened.

[0012] No. 3 The means of The basic configurationThe support means 22 is a skirt-shaped portion 30 that extends tapered from the outer surface of the outer peripheral wall 18 to the upper surface 7 of the top plate 6, and the skirt-shaped portion 30 reaches the upper end 5 of the cylindrical peripheral wall 4 at a plurality of support points A in the circumferential direction of the cylindrical peripheral wall 4.

[0013] In this means, as shown in Figure 4, the support means 22 is a skirt-shaped portion 30 that extends tapered from the outer surface of the outer peripheral wall 18 to the upper surface 7 of the top plate 6, and the skirt-shaped portion 30 reaches the upper end 5 of the cylindrical peripheral wall 4 at multiple support points A circumferentially of the cylindrical peripheral wall 4. According to this structure, the load from the dispenser 40 can be dispersed more accurately via the skirt-shaped portion 30 than in the conventional structure in which the load is concentrated on the mouth / neck portion 8.

[0014] No. 4 The means are 3 and the skirt-shaped portion 30 is formed with a lightening hole 34, When the tip end 32 of the skirt-shaped portion 30 is in contact with the upper end 5 of the body circumferential wall 4, the lower joint portion 12 pulls up the mouth / neck portion 8, causing the top plate 6 to rise in a tapered shape, In addition, a drain hole 36 is formed at the tip 32 of the skirt-shaped portion 30, opening from the inside to the outside of the skirt-shaped portion 30.

[0015] In this means, as shown in FIG. 4, the skirt-shaped portion 30 is formed with a lightening hole 34 . According to this structure, the weight of the support means 22 can be reduced. In addition, in this method, when the tip 32 of the skirt-shaped portion 30 is in contact with the upper end 5 of the body peripheral wall 4, the lower joint portion 12 pulls up the mouth and neck portion 8, causing the top plate 6 to rise in a tapered shape, and a drain hole 36 is formed in the tip 32 of the skirt-shaped portion 30, opening from the inside to the outside of the skirt-shaped portion 30. This construction prevents water from pooling on the top plate 6, reducing the possibility of the top plate 6 being weakened by moisture. [Effects of the Invention]

[0016] According to the present invention, deformation near the top plate 6 of the container body 2 in a paper container with a discharge pump can be suppressed. Also, weakening of the top plate 6 of the container body due to moisture can be prevented. [Brief explanation of the drawings]

[0017] [Figure 1] 1 is a plan view of a paper container with a discharge pump according to a first embodiment of the present invention. [Figure 2] 2. FIG. 2 is a cross-sectional view of a main part of the paper container with a discharge pump shown in FIG. [Figure 3] FIG. 10 is a plan view of a paper container with a discharge pump according to a second embodiment of the present invention. [Figure 4] 4 is a cross-sectional view of the main part of the paper container with a discharge pump shown in FIG. 3, viewed in the direction IV-IV. BEST MODE FOR CARRYING OUT THE INVENTION

[0018] 1 and 2 show a paper container with a discharge pump according to a first embodiment of the present invention. As shown in Fig. 2, this paper container with a discharge pump is formed of a container body 2, a joint member 10, and a dispenser 40. The term "paper container" means that the base material is paper, but it may contain materials other than paper (for example, a plastic film covering the surface of the paper). The paper content must be high enough that the container can be disposed of as combustible waste. The same goes for the word "paper."

[0019] The container body 2 is a box-shaped paper container, and in the illustrated example, the portions other than a mouth and neck portion 8 described below are made of paper. The container body 2 has a body wall 4 standing upright from the peripheral edge of the bottom (not shown), and a top plate 6 attached to the upper end 5 of the body wall 4, from which a mouth and neck portion 8 stands upright. The body peripheral wall 4 is rectangular cylindrical (rectangular cylindrical in the illustrated example) and is formed of four flat, vertical side wall portions w as shown in FIG. 1, but the shape can be changed as appropriate. In this embodiment, the top plate 6 is a substantially flat plate having an insertion hole h in the center, and in the illustrated example, is formed in a rectangular plate shape. Here, "substantially flat plate-like" means that it is acceptable for the shape to be slightly deformed from a flat plate when an external force is applied, as shown in FIG. 4 described later. The neck portion 8 is a portion for connecting a cylinder 42 (described later) to the inside of the container body 2, and in the illustrated example, is formed by a vertical cylindrical portion 8a having an outward flange plate portion 8b integrally protruding from the lower end thereof. The vertical cylindrical portion 8a is passed through the insertion hole h from below, and the flange plate portion 8b is adhered (welded) to the top plate 6 around the insertion hole h. A first male thread portion 9 is formed on the outer surface of the vertical cylinder portion 8a. However, these structures can be modified as appropriate.

[0020] The joint member 10 is a member that supports the dispenser 40 and connects it to the mouth / neck portion 8 so that it cannot come off. As shown in FIG. 2, the joint member 10 of this embodiment comprises a body 11 and a support means 22.

[0021] The body 11 has an upper joint portion 20 that connects to the dispenser 40 and a lower joint portion 12 that connects to the container body 2 on both the upper and lower sides of an outer wall 18 that covers the periphery of at least a portion of the cylinder 42 (in the illustrated example, the large-diameter cylinder portion 42a described below). In this embodiment, the body 11 of this embodiment has a leg tube portion 12 that hangs down from the underside of the annular base plate 14 as a lower joint portion, and is detachably fitted to the outer surface of the mouth and neck portion 8, and the upper part of the outer peripheral wall 18 that rises from the outer edge of the annular base plate 14 is used as an upper joint portion 20 for the mounting tube 47 described below. However, these structures can be modified as appropriate. In the illustrated example, a first female thread portion 13 that engages with the first male thread portion 9 is formed on the inner surface of the leg tube portion 12, and a second male thread portion 21 for screwing onto the mounting tube 47 is formed on the upper outer surface of the outer wall 18. The annular base plate 14 is placed on the upper end surface of the mouth / neck portion 8 via a first packing P1. The outer peripheral wall 18 is a portion that holds the large-diameter cylinder portion 42a. In the illustrated example, as shown in Fig. 2, the large-diameter cylinder portion 42a is inserted inside the outer peripheral wall 18 with a first gap g1 formed therebetween by engaging a locking end portion 44 (described later) with the upper end surface of the outer peripheral wall 18 via a second packing P2. In this specification, the term "hold" refers to supporting in a state of encircling, and the outer surface of the large-diameter cylinder portion 42a does not have to be fitted to the inner surface of the outer peripheral wall 18. An inner peripheral wall 16 extends vertically from the inner peripheral end of the annular base plate 14 and is inserted into the mouth / neck portion 8. In the illustrated example, a small-diameter cylinder portion 42b of a cylinder 42 (described later) extends vertically within the inner peripheral wall 16, with a second gap g2 remaining therebetween.

[0022] The support means 22 is a part that protrudes from the outer peripheral wall 18 toward the upper surface 7 of the top plate 6 and is supported on the upper end 5 of the body peripheral wall 4, and has the function of supporting the load from the dispenser 40. In this specification, the "load from the dispenser 40" includes the downward force on the head portion 56 in addition to the load of the dispenser itself. As shown in FIG. 2, the support means 22 of this embodiment is formed by a flange portion 24, a support cylinder portion 26, and an outward flange 28. The flange portion 24 protrudes outward from a suitable position on the outer peripheral wall 18 (in the illustrated example, a portion near the upper joint portion 20). The support cylinder portion 26 is suspended from the outer end of the flange portion 24 . The outward flange 28 extends outward from the lower end of the support tube portion 26 along the upper surface 7 of the top plate 6, and is formed so as to reach the upper end 5 of the circumferential wall 4 in a vertical cross section passing through imaginary line X and a vertical cross section passing through imaginary line Y shown in Figure 1 (see Figure 2). The upper end 5 in the illustrated example is a ridge (corner) between the side wall portion w and the top plate 6, and has a rigidity suitable for supporting the load from the dispenser 40. 1, a corner 27 between the support cylinder portion 26 and the outward flange 28 is rounded (R). The lower surface of the outward flange 28 outside this corner 27 is formed into a flat circumferential abutment surface T that contacts the top plate 6. In the illustrated example, this circumferential abutment surface T is the annular portion between the inner edge line t1 represented by the dotted line and the outer edge line t2 represented by the solid line in Figure 1, and by abutting against the upper surface 7 of the top plate 6, it supports the dispenser 40 so that it does not wobble. The circumferential contact surface T is placed on the upper end 5 of the circumferential body wall 4 at the point where the rectangular outline of the container body 2 intersects with the imaginary line X or the imaginary line Y in Figure 1. Hereinafter, this point will be referred to as the "support point" and will be denoted by the symbol A. In the illustrated example, the support points A are located at the midpoints of each of the four sides of the square outline of the container body 2, so that when the head portion 56 is pressed down, the pressing force is evenly distributed to the four side wall portions w of the body peripheral wall 4.

[0023] Dispenser 40 includes a cylinder 42 , a mounting member 46 , and an actuating member 50 . The dispenser 40 in the illustrated example is configured as a foam pump (foam dispenser), but this structure can be modified as appropriate, and for example, it may be a spray-type dispenser or the like.

[0024] The cylinder 42 is mounted on the upper side of the mouth / neck portion 8. According to this configuration, compared to a structure in which the cylinder 42 is built into the container body 2, the volume that can be used to store liquid is larger. In this specification, "mounted" means that the majority of the cylinder 42 is assembled to the upper side of the mouth / neck portion 8, and it is acceptable for a part of the cylinder 42 (small diameter cylinder portion 42b) to hang down into the mouth / neck portion 8. The illustrated cylinder 42 has a large-diameter cylinder portion 42a and a small-diameter cylinder portion 42b suspended from it. The upper end of the large-diameter cylinder portion 42a serves as a large-diameter locking end portion 44, which is placed on the upper end of the outer peripheral wall 18, and the small-diameter cylinder portion 42b passes through the inner peripheral wall 16 and hangs down into the container body 2. An air hole i is opened in the large diameter cylinder portion 42a, and this air hole i communicates with the inside of the container body 2 via the first gap g1 and the second gap g2.

[0025] The mounting member 46 serves to prevent the cylinder 42 and an operating member 50 (described later) from being pulled out upward. The mounting member 46 has an inward flange 49 protruding inward from the upper end of a mounting tube 47 connected to the upper joint portion 20, preventing the cylinder 42 from slipping out from within the neck portion 8 and the operating member 50 from slipping out from within the cylinder 42. A second female thread portion 48 that engages with the second male thread portion 21 is formed on the inner surface of the mounting tube 47.

[0026] The actuating member 50 has a conventionally known structure, and so to briefly explain it, a head portion 56 with a discharge port 58 is attached to the upper end of a stem 54 that rises from within the cylinder 42, and the actuating member 50 is biased upward as a whole. The actuating member 50 is configured to suck up the liquid in the container body 2 into the cylinder 42 by moving up and down relative to the cylinder 42, and to discharge the contents in the cylinder 42 from the discharge port 58 to the outside. The actuating member 50 in the illustrated example has a small-diameter piston 52B fitted in the small-diameter cylinder portion 42b and a large-diameter piston 52A fitted in the large-diameter cylinder portion 42a, and is configured to mix the liquid in the small-diameter cylinder portion 42b with the air in the large-diameter cylinder portion 42a to form bubbles and discharge them from the discharge port 58.

[0027] In the above configuration, as shown in FIG. 2, the joint member 10 supports the load from the dispenser 40 on the body peripheral wall 4 of the container body 2 via a support means 22 protruding from the outer peripheral wall 18 that embraces the cylinder 42 of the dispenser 40. In addition, the joint member 10 is connected to the neck portion 8 and the mounting tube 47 of the dispenser 40 on both sides of the outer wall 18, thereby preventing the dispenser 40 from slipping out upward from the neck portion 8. As a result, when the head portion 56 is pressed down, the pressing force is evenly distributed to the four side wall portions w of the circumferential barrel wall 4 .

[0028] According to the above-mentioned configuration and action, a support means 22 supported on the upper end 5 of the trunk peripheral wall 4 of the container body 2 is protruded from the outer wall 18 of the joint member 10 that connects the mouth and neck portion of the container body 2 and the mounting tube 47 of the dispenser 40, so that deformation of the top plate 6 of the container body 2 can be suppressed. Furthermore, since the load from the dispenser 40 is dispersed over a wide range via the circumferential contact surface T that surrounds the mouth and neck portion 8, deformation of the top plate 6 can be further reduced. A ring-shaped outward flange 28 extends along the upper surface 7 of the top plate 6 from the lower end of the support tube portion 26 suspended from the outer surface of the outer wall 18, reducing the possibility that the inner periphery of the top plate 6 will come into contact with water and become weakened.

[0029] Other embodiments of the present invention will be described below, and in these descriptions, explanations of structures that are the same as those in the first embodiment will be omitted.

[0030] 3 and 4 show a paper container with a discharge pump according to a second embodiment of the present invention. In this embodiment, the structure of the support means 22 in the first embodiment is modified. That is, the support means 22 in this embodiment is a skirt-like portion 30 that expands from an appropriate position on the outer peripheral wall 18 (near the lower end of the outer peripheral wall 18 in the illustrated example) to the upper surface of the top plate 6 . This skirt-shaped portion 30 is frusto-conical (meaning a shape with the top of a cone cut off) and is formed so as to extend from the outer peripheral wall 18 to the upper end 5 of the body peripheral wall 4 when viewed in a vertical cross section passing through imaginary line X and a vertical cross section passing through imaginary line Y in Figure 3 (see Figures 3 and 4). The tip end 32 of the skirt portion 30 is formed as a ring plate having a constant width in the cylindrical diameter direction of the outer peripheral wall 18, and the lower surface of the ring plate serves as a circumferential abutment surface T.

[0031] In this embodiment, the skirt portion 30 has a lightening hole 34 formed therein. In the illustrated example, as shown in FIG. 3, a first bridge b1 in the radial direction and a second bridge b2 in the circumferential direction are left, and arc-shaped lightening holes 34 are drilled when viewed from above. This reduces the weight of the support means 22. In this embodiment, a plurality of narrow groove-shaped drain holes 36 that open radially are drilled in the underside of the tip portion 32, as shown in the right half of Figure 4. This is to prevent water that has entered through the drain holes 34 from accumulating on the top plate 6, since the container of the present invention is intended to be used in wet areas such as washbasins and bathrooms. In the illustrated example, as shown in the left half of FIG. 4, the drain holes 36 are arranged at equal intervals in the circumferential direction. Furthermore, in this embodiment, the lower joint portion 12 is designed to lift up the mouth / neck portion 8 while the tip portion 32 of the support means 22 is pressed against the upper end of the body circumferential wall 4 . By doing so, as shown in FIG. 4, the top plate 6 is raised in a tapered shape, and the inner periphery of the top plate is raised by a distance d. This allows water to fall from the lightening holes 34 onto the top plate 6, then flow outward (radially outward from the top plate 6) over the inclined top plate 6 and be drained through the drainage holes 36. However, these structures can be modified as appropriate.

[0032] According to the above configuration, the support means 22 is provided with a skirt-shaped portion 30 that extends tapered from the outer surface of the outer peripheral wall 18 to the upper surface 7 of the top plate 6 and reaches the upper end 5 of the body peripheral wall 4, so that the load from the dispenser 40 can be accurately distributed. Furthermore, since the skirt-shaped portion 30 is formed with the lightening holes 34, the weight of the support means 22 can be reduced. Furthermore, when the tip 32 of the skirt-shaped portion 30 is in contact with the upper end 5 of the body wall 4, the lower joint portion 12 pulls up the mouth and neck portion 8, causing the top plate 6 to rise in a tapered shape, and a drain hole 36 is formed in the tip 32 of the skirt-shaped portion 30, opening from the inside to the outside of the skirt-shaped portion 30, thereby preventing water from accumulating on the top plate 6 and reducing the risk of the top plate 6 being weakened by moisture.
