Description

  The present invention relates to a pet drinking container for providing a beverage to a dog or the like that can be attached to a container such as a commercially available PET bottle.

For example, many dogs, which are a kind of pet, generally need to take a walk outdoors one or more times a day. In particular, in the season when the outside air temperature is high such as summer, a dog that takes a walk may drink puddle water or relatively dirty water such as a drain.
The owner appears to be uncomfortable with family-like dogs drinking such dirty water. However, it is extremely rare for a walk companion to carry water for the dog to drink so that this is not the case.
The reason for this is that there is no appropriate drinking container for dogs that can be easily carried for a walk, in addition to not being able to carry drinking water.

By the way, in recent years, sports drinks, teas, juices, and the like that are sold by being filled in 500 ml PET (polyethylene terephthalate) resin containers are frequently used when going out. As described above, various accessories for making the use more convenient are provided by a third party in a PET resin container that is sold in large quantities and used for convenience.
Some of the accessories prepared by the third party can be attached to a PET resin container as disclosed in, for example, Patent Document 1 and Patent Document 2, and drinks in a PET resin container by a plurality of people. There are cups for sanitary consumption.

FIG.
The pet drinking container 1 includes a main body 2 and a water sprinkling unit 3.
The main body 2 includes a flange part 11, an extension part 12, and a coupling part 13.
The collar portion 11 is continuous with a spherical shell portion 21 formed in a substantially hemispherical shell shape and a circular end edge of the spherical shell portion 21 (because this “end edge” does not actually exist, hereinafter referred to as “virtual end edge”). It is formed by a short cylindrical cylindrical portion 22.

The spherical shell 21 has an inner diameter 23 which is commercially available with tea or sports drinks filled therein, and the outer diameter of a 500 ml container (hereinafter referred to as “PET bottle PB”) having a circular cross section made of PET resin, and The PET bottle having a polygonal cross section has a spherical shape having a radius of curvature larger than any of the distance between the center of the cross section and the outer surface of the apex angle.
The cylindrical portion 22 has a cylindrical inner surface 24a, one of which is substantially divided into two by a virtual plane IP (see FIG. 6) extending in the axial direction, and the inner diameter slightly decreases as the other moves away from the virtual end surface. This is a circumferential inner surface 24b of the truncated cone. The boundary portion between the one inner surface 24a and the other inner surface 24b gradually changes from one shape to the other shape.

  The expanded portion 12 is a part of a cylinder having a truncated cone shape in which the outer peripheral surface 24b of the truncated cone shape in the cylindrical portion 22 is expanded outward as it is, and the axial center side of the cylindrical portion 22 is concave. It is formed as a shape like More specifically, the shape of a part of this truncated cone-shaped cylinder is more specifically a plane RP (FIG. 1) in which the outermost edge 25 of the cylinder is orthogonal to the axis of the truncated cone-shaped cylinder. , 2), and the edge from the both ends of the outermost edge 25 to the cylindrical portion 22 becomes closer to the cylindrical portion 22 and the inclination angle with the plane RP increases. Shape. Therefore, the end edge of the extended portion 12 is similar to a shape obtained by dividing the ellipse into four equal parts in the front view (FIG. 3).

The cap portion 31 is provided with a cap support portion 31 at a position farthest from the extended portion 12 at the virtual edge. The cap support part 31 is formed by a support part 32 and a retaining part 33. The support portion 32 is a short quadrangular prism-like portion that protrudes outward from the expansion portion 12. The retaining portion 33 has a rectangular plate shape larger than the cross-sectional shape of the support portion 32, and is a portion that protrudes around the protruding end of the support portion 32. The cap support part 31 is for supporting the cap member 4 that closes the water spray holes 43,... 43 provided in the water spray part 3.
On the virtual end edge, handle support portions 34 and 34 for supporting the handle are provided at two positions orthogonal to the cap support portion 31 by 90 degrees.

The coupling portion 13 has a substantially cylindrical shape (therefore, the inner surface is substantially columnar). The coupling part 13 protrudes inward from the deepest part inside the collar part 11 in the main body 2 so that the extension line of the axis passes through the spherical center of the spherical shell part 21. On the inner surface of the coupling portion 13, a female screw capable of screwing the male screw of the drinking mouth 71 in the PET bottle PB is provided.
The water sprinkling part 3 is a hollow truncated cone whose shape has only the upper bottom. Here, the “upper base” refers to the smaller one of the two bottom surfaces of the truncated cone, and the upper base in the following description is also synonymous. In addition, the upper base mentioned above about the sprinkling part 3 is not the upper base in the truncated cone as a three-dimensional figure, but is located inward slightly from the upper bottom side end, and closes the opening part. Hereinafter, what closes the opening is referred to as an upper bottom 41. In the water sprinkling part 3, a recess in which the upper bottom part 41 forms the bottom (there) is formed at the end part on the upper bottom part 41 side. The shape of the recess is a truncated cone with the top and bottom inverted, and the inner diameter at the bottom is the smallest.

The water sprinkling part 3 is integrated with the main body 2 so that its axial center coincides with the axial center of the coupling part 13 and protrudes outward from the main body 2. An annular locking ring 42 that protrudes outward is provided on a portion of the outer surface of the sprinkler 3 close to the main body 2 (see FIGS. 3 to 6).
The upper bottom 41 is provided with a plurality of water spray holes 43 having a large opening diameter on the inside and a small opening diameter on the outside.
The inside of the pet drinking container 1 communicates with the outside through watering holes 43. The pet drinking container 1 is made of a synthetic resin such as polyethylene, polypropylene, melamine resin, or phenol resin.

A cap member 4 is attached to the pet drinking container 1 to prevent unintended leakage of the PET bottle PB contents from the water sprinkling unit 3.
7 is a plan view of the cap member 4, and FIG. 8 is a cross-sectional view taken along the line AA in FIG.
The cap member 4 includes a cap portion 15 and a belt portion 16.
The cap portion 15 has a hollow truncated cone shape in which a portion corresponding to the upper base is closed. A frustoconical water-stopping portion 51 that is substantially equal to the shape of the dent in the water sprinkling portion 3 protrudes inward at a portion that closes the upper bottom. The water stop part 51 can be fitted into the recess on the upper bottom side of the water spray part 3 in the pet drinking container 1.

An annular decorative ring 52 is provided on the upper bottom of the cap member 4 so as to surround the opening of the water stop portion 51.
The cap member 4 is designed to have a shape in which, when the water stop portion 51 is fitted in the recess of the water sprinkling portion 3, the other inner surface is substantially in close contact with and covers the outer surface of the water sprinkling portion 3. On the inner surface of the cap member 4 in the vicinity of the lower bottom, two belt-like engagement bands 53, 53 that extend in a predetermined range in the circumferential direction and protrude moderately are provided at positions opposed to each other by 180 degrees.
The belt portion 16 includes a belt portion 54 having an elongated belt shape and an attachment portion 55. One end of the band portion 54 is continuous with the vicinity of the lower bottom of the cap member 4. The other end of the band portion 54 is continuous with an attachment portion 55 for attachment to the main body 2. The attachment portion 55 is wider than the belt portion 54 and is provided with an attachment hole 56 penetrating the front and back. The attachment hole 56 has a length (lateral dimension in FIG. 7) that is substantially equal to a longitudinal length of the retaining portion 33 in the pet drinking container 1, and a width that is greater than the width of the support portion 32 (lateral dimension in FIG. 4). Is also smaller than the width of the retaining portion 33 (lateral dimension in FIG. 4).

The cap member 4 is provided with a handle 57 at a portion 180 degrees away from a portion continuous with the belt portion 16 in the cap portion 15.
The cap member 4 is made of a resin such as polyethylene or polypropylene having moderate flexibility.
The cap member 4 is attached to the pet drinking container 1 by passing the retaining portion 33 of the pet drinking container 1 through the attachment hole 56 (see FIG. 1). The cap portion 15 is configured so that the water stop portion 51 closes the outward opening portion of the water spray holes 43,..., 43 and prevents the unintended leakage of the PET bottle PB contents from the water spray portion 3. Be put on. The cap part 15 covered with the water spray part 3 has the engagement bands 53 and 53 locked by the lock ring 42, thereby preventing unintentional dropping from the water spray part 3.

A handle (belt) that is convenient for carrying during a walk or the like can be attached to the two handle support portions 34, 34 of the pet drinking container 1.
The pet drinking container 1 is attached to the PET bottle PB by removing the cap attached to the PET bottle PB at the time of marketing and screwing the male screw of the drinking mouth 71 into the female screw of the coupling portion 13.
FIG. 9 is a cross-sectional view of the pet drinking container 1 containing water Wa.
As shown in FIG. 9, when the pet drinking container 1 does not have the expansion part 12, the pet drinking container 1 has the expansion part 12, for example, even when the dog is tilted so as to easily drink the water Wa. Compared to this, an extremely large amount of water Wa can be added.

Moreover, when the pet drinking container does not have the extended part 12, the area of the opening part is small, and the nose which the dog protruded hits the opening part, and it is difficult to drink water Wa. On the other hand, the pet drinking container 1 having the expanded portion 12 has a large area of the opening, and the dog can easily drink the water Wa without disturbing the nose.
FIG. 10 is a cross-sectional view of the pet drinking container 1 for watering.
The pet drinking container 1 can be used for washing away pee that the dog has used as a gate pillar of another person's house during a walk or the like. When the pee is washed away, the cap member 4 that covers the watering part 3 of the pet drinking container 1 is removed, and as shown in FIG. 10, the watering part 3 is directed to the target part, and then the PET bottle PB is pressed by hand. In the compressed PET bottle PB, the internal pressure increases, and the filled water Wa is pushed out from the sprinkling holes 43,..., 43, and the pee is washed away by the water Wa ejected. Sprinkling from the water sprinkling unit 3 is also effective for washing roads and the like after removing feces during a walk.

Thus, the pet drinking container 1 can cope with various situations that occur when the dog walks by combining with the PET bottle PB after consuming the contents.
FIG. 11 is a diagram showing an outline of the expansion portion 12 in the pet drinking container 1.
As described above, the extended portion 12 has an effect of increasing the opening area of the edge of the pet drinking container 1 so that the dog can easily drink when drinking a liquid such as water. The extended portion 12 having such an effect is preferably formed as defined below.
That is, referring to FIG. 11, the extended portion 12 has a concave shape on the one side divided by a virtual plane HJ including the axis of the substantially cylindrical coupling portion 13 on the one side. Thus, it expands outward (from the main body 2) in the axial direction of the coupling portion 13 (in a direction far away from the coupling portion 13, downward in FIG. 11).

Further, the extended portion 12 is inclined by 45 degrees with respect to the virtual plane HJ, and a virtual plane SD that contacts the circular end edge 35 at the protruding end of the coupling portion 13 at one point F, and the virtual plane HJ. Is formed in a portion that extends outward in the axial direction of the coupling portion 13 rather than the position C where the crossing points.
The expansion part 12 in the pet drinking container 1 is a part that continues to (a part of) the collar part 11 on a virtual plane B-L orthogonal to the axis of the coupling part 13 and extends away from the coupling part.
The right side of the virtual plane HJ shown in FIG. 11 and the lower side of the virtual plane SD in the buttock 11 is that the owner's hand gets wet by the water that jumps when the dog drinks water with the tongue. Work to prevent.

The sizes of the drinking mouth 71 of the commercially available PET bottle PB and the female screw provided in the drinking mouth 71 are substantially the same regardless of the manufacturer of the drinking water commercially available. The size of the coupling portion 13 for matching is also limited by the size of the drinking mouth 71 and the female screw. Therefore, the expansion part 12 can be defined by the size of the coupling part 13.
FIG. 12 is a front view of the pet drinking container 1B in which the expanded portion 12B is provided in the range defined as described above. In the pet drinking container 1B, the collar portion 11B has a shape in which one of the four equal parts is removed from the hemispherical shell. The extended portion 12B has a continuous edge in a straight line when viewed from the front (FIG. 12) with an edge inclined at 45 degrees with respect to the imaginary plane H-J of the flange portion 11B. It spreads towards.

Such a pet drinking container 1B having the edge of the main body 2B on the virtual plane SD is more open than a pet drinking container having an edge on the virtual plane PL perpendicular to the axis of the coupling portion 13. For example, dogs with a large area and a relatively short nose are easy to drink water.
Since the pet drinking container 1B has few gripping points when screwing the PET bottle PB to the collar part 11B, the collar part 11B may have a hemispherical shell shape like the collar part 11 in the pet drinking container 1. .
The degree of expansion (length in the axial direction) of the expansion portions 12 and 12B of the pet drinking containers 1 and 1B outward in the axial direction of the coupling portion 13 is not limited. First, the shape is determined in consideration of aesthetics when integrated with the PET bottle PB.

The coupling portion 13C is substantially cylindrical. The coupling portion 13 </ b> C has an axial extension extending through the spherical center of the spherical shell portion 21, one end opening to the deepest inner portion of the flange portion 11, and protruding outward from the flange portion 11 as a whole. 13 C of coupling parts are provided in the inner surface with the internal thread which can screw the external thread of the drinking mouth 71 in PET bottle PB. The other end from which the coupling portion 13C protrudes is closed, and a plurality of water spray holes 43 penetrating the inside and outside of the coupling portion 13C are provided in the closed portion. The coupling portion 13C in the pet drinking container 1C is usually covered with a cap portion of a dedicated cap member, and the outer openings of the water spray holes 43, 43, 43 are closed. 13 C of coupling | bond parts also have a function of the water sprinkling part 3 in the pet drinking container 1. FIG.

The expansion part 12 of the pet drinking container 1C is preferably formed as defined below.
Referring to FIG. 13, the extended portion 12 is connected to the side of the coupling portion 13 </ b> C from the edge of the flange portion 11 on one side divided by a virtual plane HJ including the axis of the substantially cylindrical coupling portion 13. It spreads in a direction far away from the coupling portion 13C in the axial direction.
Further, the extended portion 12 is inclined 45 degrees with respect to the virtual plane H-J, and the inner surface (circular cylindrical shape) of the coupling portion 13C is inward of the flange portion 11 by the same length t as its height t. Portion extending outward in the axial direction of the coupling portion 13C rather than the position C where the virtual plane SD that contacts the circular end edge 35C at one point F and the virtual plane HJ intersect Formed.

In the above-described embodiment, the spherical shell portion 21 in the pet drinking containers 1, 1B, 1C may have another shape such as a regular polygonal frustum, a cylinder, or a regular polygonal column, instead of a substantially hemispherical appearance. The shape of the spherical shell portion 21 is not limited as long as it does not hinder the integration of the PET bottle PB with the coupling portion 13.
The flange portion 11 may have a shape in which the extended portion 12 is not directly connected to the spherical shell portion 21 without the cylindrical portion 22. Further, as shown in FIG. 12, the flange portion 11 </ b> B can have a three-dimensional shape with no end edge in the plane.

The shape and size of the extended portion 12 are not limited as long as they do not prevent the PET bottle PB from being integrated with the coupling portions 13 and 13C.
The coupling parts 13 and 13C are not provided with a female screw that can be screwed into the drinking mouth 71 of the PET bottle PB on the inner surface, and a cap is fitted into the drinking mouth 71 with a cap at the time of marketing attached. It is good also as a structure integrated with PB.
The pet drinking containers 1, 1 </ b> B can be formed as having no sprinkler 3. In that case, the pet drinking container has the shape of a truncated cone in FIGS. 1 to 5 and does not have a portion projecting upward, and the upper end of the coupling portion 13 is closed so that the PET bottle PB can be mounted. Outflow of the contents in is prevented. In addition, the pet drinking container 1C may be configured such that the sprinkling holes 43, 43, 43 are not provided in the coupling portion 13C. In that case, the cap member for closing the watering hole 43 is unnecessary.
